Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.

Correlation between the status of the p53 gene and survival in patients with stage I non-small cell lung carcinoma. (1/18612)

The association of p53 abnormalities with the prognosis of patients with non-small cell lung carcinoma (NSCLC) has been extensively investigated to date, however, this association is still controversial. Therefore, we investigated the prognostic significance of p53 mutations through exons 2 to 11 and p53 protein expression in 103 cases of stage I NSCLC. p53 mutations were detected in 49 of 103 (48%) tumors. Two separate mutations were detected in four tumors giving a total of 53 unique mutations in 49 tumors. Ten (19%) of mutations occurred outside exons 5-8. Positive immunohistochemical staining of p53 protein was detected in 41 of 103 (40%) tumors. The concordance rate between mutations and protein overexpression was only 69%. p53 mutations, but not expression, were significantly associated with a shortened survival of patients (P<0.001). Furthermore, we investigated the correlation between the types of p53 mutations and prognosis. p53 missense mutations rather than null mutations were associated with poor prognosis (P < 0.001 in missense mutations and P=0.243 in null mutations). These results indicated that p53 mutations, in particular missense mutations, rather than p53 expression could be a useful molecular marker for the prognosis of patients with surgically resected stage I NSCLC.  (+info)

Comparative efficacy of positron emission tomography with FDG and computed tomographic scanning in preoperative staging of non-small cell lung cancer. (2/18612)

OBJECTIVE: To determine the sensitivity, specificity, and accuracy of positron emission tomography with 2-fluorine-18-fluorodeoxyglucose (PET-FDG) in the preoperative staging (N and M staging) of patients with lung cancer. The authors wanted to compare the efficacy of PET scanning with currently used computed tomography (CT) scanning. MATERIALS AND METHODS: Results of whole-body PET-FDG imaging and CT scans were compared with histologic findings for the presence or absence of lymph node disease or metastatic sites. Sampling of mediastinal lymph nodes was performed using mediastinoscopy or thoracotomy. RESULTS: PET-FDG imaging was significantly more sensitive, specific, and accurate for detecting N disease than CT. PET changed N staging in 35% and M staging in 11% of patients. CT scans helped in accurate anatomic localization of 6/57 PET lymph node abnormalities. CONCLUSION: PET-FDG is a reliable method for preoperative staging of patients with lung cancer and would help to optimize management of these patients. Accurate lymph node staging of lung cancer may be ideally performed by simultaneous review of PET and CT scans.  (+info)

A blind comparison of the effectiveness of endoscopic ultrasonography and endoscopy in staging early gastric cancer. (3/18612)

BACKGROUND/AIMS: Endoscopic ultrasonography is expected to be useful for invasion depth staging of early gastric cancer. A prospective blind study of the staging characteristics of endoscopy and endoscopic ultrasonography for early gastric cancer was performed. METHODS: Findings of endoscopy and endoscopic ultrasonography using a 20 MHz thin ultrasound probe were independently reviewed and the results of 52 early gastric cancer lesions analysed. RESULTS: The overall accuracy rates in invasion depth staging of early gastric cancer were 63% for endoscopy and 71% for endoscopic ultrasonography. No statistically significant differences were observed in overall accuracy. Endoscopic ultrasonography tended to overstage, and lesions that were classified as mucosal cancer by endoscopic ultrasonography were very likely (95%) to be limited to the mucosa on histological examination. All 16 lesions staged as mucosal cancer independently but coincidentally by both methods were histologically limited to the mucosa. CONCLUSIONS: Endoscopic ultrasonography is expected to compensate for the understaging of lesions with submucosal invasion that are endoscopically staged as mucosal cancer.  (+info)

Evidence of improving survival of patients with rectal cancer in france: a population based study. (4/18612)

BACKGROUND: Over the past 20 years there have been many changes in the management of rectal cancer. Their impact on the overall population is not well known. AIMS: To determine trends in management and prognosis of rectal cancer in two French regions. SUBJECTS: 1978 patients with a rectal carcinoma diagnosed between 1978 and 1993. METHODS: Time trends in treatment, stage at diagnosis, operative mortality, and survival were studied on a four year basis. A non-conditional logistic regression was performed to obtain an odds ratio for each period adjusted for the other variables. To estimate the independent effect of the period a multivariate relative survival analysis was performed. RESULTS: Over the 16 year period resection rates increased from 66.0% to 80.1%; the increase was particularly noticeable for sphincter saving procedures (+30.6% per four years, p=0.03). The percentage of patients receiving adjuvant radiotherapy increased from 24.0% to 40.0% (p=0.02). The proportion of patients with Dukes' type A cancer increased from 17. 7% to 30.6% with a corresponding decrease in those with more advanced disease. Operative mortality decreased by 31.1% per four years (p=0.03). All these improvements have resulted in a dramatic increase in relative survival (from 35.4% for the 1978-1981 period to 57.0% for the 1985-1989 period). CONCLUSIONS: Substantial advances in the management of rectal cancer have been achieved, but there is evidence that further improvements can be made in order to increase survival.  (+info)

Immunocytochemically detected free peritoneal tumour cells (FPTC) are a strong prognostic factor in gastric carcinoma. (5/18612)

We prospectively investigated the prognostic significance of free peritoneal tumour cells (FPTC) in a series of 118 patients with completely resected gastric carcinoma. Immunocytochemistry with the monoclonal antibody Ber-Ep4 was performed on cytospins from intraoperative peritoneal lavage specimens. Twenty-three patients (20%) had FPTC which was significantly correlated with pT and pN categories, stage, tumour size, lymphatic invasion, Lauren and WHO classifications and perigastric adipose tissue metastases. The median survival time for all FPTC positive compared with negative patients was significantly shorter (11 compared with >72 months), with estimated 5-year survival rates of 8% vs. 60%. None of the patients with FPTC had an early gastric cancer. In advanced tumour subgroups without and with serosal invasion (n = 59 and 35), there were 19% and 34% with FPTC. Multivariate survival analysis showed nodal status, FPTC, mesenteric lymphangiosis, and lymph node metastasis to the compartment III to be independent prognostic factors with relative risks of 6.6, 4.5, 2.9 and 2.2 respectively. Recurrent disease occurred in 91% of FPTC-positive and in 38% of FPTC-negative patients. FPTC had a positive predictive value of 91% and a specificity of 97% for tumour recurrence. FPTC is a strong negative, independent prognostic indicator for survival in gastric carcinoma.  (+info)

Elevated serum thymidine kinase levels identify a subgroup at high risk of disease progression in early, nonsmoldering chronic lymphocytic leukemia. (6/18612)

Chronic lymphocytic leukemia (CLL) shows a remarkably heterogeneous clinical outcome; survival ranges from several months in advanced stages to more than 10 years in early stages. The Binet and Rai staging systems distinguish three major prognostic subgroups, but do not accurately predict the individual risk of disease progression in early CLL (Binet stage A or Rai stage 0 to II). Because most newly diagnosed CLL patients present with early disease, it seems desirable to search for additional prognostic factors to identify early CLL patients at high risk of rapid progression. It has been shown that elevated serum thymidine kinase (s-TK) levels predict disease progression in CLL. Therefore, this study aimed to assess the prognostic value of s-TK in 122 previously untreated patients with Binet stage A CLL (mean age +/- SD, 58.7 +/- 8.5 years). In univariate analyses, 18 of the 22 parameters investigated predicted progression-free survival (PFS). In a stepwise multiple regression analysis, only three parameters provided independent prognostic information on PFS: s-TK greater than 7.1 U/L; presence of lymphadenopathy; and white blood cell (WBC) count greater than 75, 000/microL. When added to the classification of smoldering versus nonsmoldering CLL, s-TK levels separated two groups within the group of nonsmoldering stage A patients: patients with s-TK values greater than 7.1 U/L had a median PFS of 8 months, whereas patients with s-TK values +info)

Detection of occult lymph node metastases in esophageal cancer by minimally invasive staging combined with molecular diagnostic techniques. (7/18612)

BACKGROUND AND OBJECTIVES: Lymph node metastases are the most important prognostic factor in patients with esophageal cancer. Histologic examination misses micrometastases in up to 20% of lymph nodes evaluated. In addition, non-invasive imaging modalities are not sensitive enough to detect small lymph nodes metastases. The objective of this study was to investigate the use of reverse transcriptase-polymerase chain reaction (RT-PCR) of messenger RNA (mRNA) for carcinoembryonic antigen (CEA) to increase the detection of micrometastases in lymph nodes from patients with esophageal cancer. METHODS: RT-PCR of CEA mRNA was performed in lymph nodes from patients with malignant and benign esophageal disease. Each specimen was examined histopathologically and by RT-PCR and the results were compared. RESULTS: Metastases were present in 29 of 60 (48%) lymph nodes sample by minimally invasive staging from 13 patients with esophageal cancer when examined histopathologically. RT-PCR identified nodal metastases in 46 of these 60 (77%) samples. RT-PCR detected CEA mRNA in all 29 histologically positive samples and in 17 histologically negative lymph nodes. All lymph nodes from patients with benign disease (n = 15) were negative both histopathologically and by RT-PCR. The stage of two patients was reclassified based on the RT-PCR results, which identified lymph node spread undetected histopathologically. Both of these patients developed recurrent disease after resection of the primary tumor. CONCLUSIONS: RT-PCR is more sensitive than histologic examination in the detection of lymph node metastases in esophageal cancer and can lead to diagnosis of a more advanced stage in some patients. The combination of minimally invasive surgical techniques in combination with new molecular diagnostic techniques may improve our ability to stage cancer patients.  (+info)

Molecular detection of tumor cells in bronchoalveolar lavage fluid from patients with early stage lung cancer. (8/18612)

BACKGROUND: Conventional cytologic analysis of sputum is an insensitive test for the diagnosis of non-small-cell lung cancer (NSCLC). We have recently demonstrated that polymerase chain reaction (PCR)-based molecular methods are more sensitive than cytologic analysis in diagnosing bladder cancer. In this study, we examined whether molecular assays could identify cancer cells in bronchoalveolar lavage (BAL) fluid. METHODS: Tumor-specific oncogene mutations, CpG-island methylation status, and microsatellite alterations in the DNA of cells in BAL fluid from 50 consecutive patients with resectable (stages I through IIIa) NSCLC were assessed by use of four PCR-based techniques. RESULTS: Of 50 tumors, 28 contained a p53 mutation, and the identical mutation was detected with a plaque hybridization assay in the BAL fluid of 39% (11 of 28) of the corresponding patients. Eight of 19 adenocarcinomas contained a K-ras mutation, and the identical mutation was detected with a mutation ligation assay in the BAL fluid of 50% (four of eight) of the corresponding patients. The p16 gene was methylated in 19 of 50 tumors, and methylated p16 alleles were detected in the BAL fluid of 63% (12 of 19) of the corresponding patients. Microsatellite instability in at least one marker was detected with a panel of 15 markers frequently altered in NSCLC in 23 of 50 tumors; the identical alteration was detected in the BAL fluid of 14% (three of 22) of the corresponding patients. When all four techniques were used, mutations or microsatellite instability was detected in the paired BAL fluid of 23 (53%) of the 43 patients with tumors carrying a genetic alteration. CONCLUSION: Although still limited by sensitivity, molecular diagnostic strategies can detect the presence of neoplastic cells in the proximal airway of patients with surgically resectable NSCLC.  (+info)

INTRODUCTION & OBJECTIVES: The 2010 TNM staging system provided several changes in pT classification: pT2 stage is splitted in pT2a (,= 10 cm) and pT2b (,10 cm); patients with tumor thrombus invading the renal vein are classified as pT3a; infiltration of the wall of the vena cava as pT3c; direct invasion of the adrenal gland is inserted in pT4 stage. Moreover all nodal involvement is classified as pN1. We aimed to analyze wether the new TNM staging system is more accurate than the 2002 TNM classification in predicting the risk of cancer-specific mortality (CSM). MATERIAL & METHODS: We retrospectively analyzed data of 14040 consecutive patients who underwent radical nephrectomy or nephron-sparing surgery for RCC, between 1987 and 2008. The Kaplan-Meier method and univariable and multivariable Cox regression analyses were used to determine the effect of the 2002 TNM and of the new TNM staging system on CSM. Finally, we compared the accuracy of the 2002 TNM and of the 2010 TNM staging system ...
Patients with potentially resectable gastric cancer should undergo multidisciplinary evaluation. The new staging system and treatment guidelines will improve outcomes for patients with esophageal carcinoma. The 7th edition of the AJCC Cancer Staging Manual improves the T designations for T1 and T4 tumors, improves the prognostic stratification of the N status by incorporating nodal involvement quantitatively, and has added clearer definitions for M1 disease to optimize treatment options.. Despite the improvements made in the most recent classification, several controversial issues still impact treatment guidelines. The most significant one relates to GEJ tumors.. GEJ Issues: Another important change in the recently adopted 7th AJCC/Union Internationale Contre le Cancer (UICC) staging system for esophageal and gastric cancer is a clearer definition of GEJ tumors. This presents a frequent controversy for surgical and medical oncologists, and similar patients with involvement just above or below ...

To our knowledge, there are no studies to systematically compare the detailed clinical significance between curatively resected pancreatic head (ph) and body-tail (pbt) ductal adenocarcinoma based on the new 8th edition of AJCC staging system (8th AJCC stage) that was just applied in clinical practice in 2018. Three hundred fifty-one patients with curatively resected pancreatic adenocarcinoma (PC) from three center hospitals were entered into this multicenter cohort study. Increasing tumor size (P | 0.001), T stage (T1 + T2 vs T3 + T4, P = 0.003), frequent postoperative liver metastasis (PLM) (P = 0.002) and 8th AJCC stage (IA to VI, P | 0.001; I + II vs III + IV, P = 0.002) were closely associated with the progression of pbt cancers compared with that in ph cancer patients. Moreover, tumor size≥3 cm (P = 0.012), 8th AJCC stage (III + IV) (P = 0.025) and PLM (P = 0.010) were identified as independent risk factors in pbt cancers in logistic analysis. Patients with pbt cancers had a significantly worse

To determine the stage of a tumor, a healthcare provider may order lab tests, X-rays, or other procedures depending on each individual case.. Cancer staging can be categorized into clinical stage and pathologic stages. The clinical staging is performed before the tumor is removed. The healthcare professional may use a variety of tools, such as blood test, imaging studies (such as Ultrasound scans, Computed Tomography or CT scans, Magnetic Resonance Imaging or MRI scans, Positron Emission Tomography or PET scans, and Bone scans) and physical examination. The pathologic staging is performed when the pathologist examines the tumor tissue after the surgery.. In general, the pathologic stage is more accurate than clinical stage. However, since the two staging systems use different methods, they may differ frequently. In many cases, the information derived from the two staging methods complement each other. Sometimes, treatments such as radiation therapy or chemotherapy are initiated before surgery. ...
Accurate diagnosis and staging is crucial to ensure uniform allocation to the optimal treatment modalities for non-small cell lung cancer (NSCLC), but may differ between multidisciplinary tumor boards (MDT). Discordance between clinical and pathological TNM-stage is particularly important for patients with locally advanced NSCLC (stage IIIA) because it may influence their chance of allocation to curative intent treatment. We therefore aimed to study agreement on staging and treatment to gain insight in MDT decision making.What is the level of agreement on clinical staging and treatment recommendations between MDTs in stage IIIA NSCLC patients?Eleven MDTs each evaluated the same 10 pathological stage IIIA NSCLC patients in their weekly meeting (n=110). Cases were purposively selected for their challenging nature. All MDTs received exactly the same clinical information and images per patient. We tested agreement in cT-stage, cN-stage, cM-stage (TNM 8th edition) and treatment proposal between ...
Prognostication of newly diagnosed colorectal cancer (CRC) predominantly relies on stage as defined by the UICC-TNM and American Joint Committee on Cancer classifications. Tumour extent, lymph node status, tumour grade and the assessment of lymphatic and venous invasion are still the most important morphological prognostic factors. Evidence suggests that tumour budding and tumour border configuration are important, additional histological parameters but are not regarded as essential in prognosis. Although several molecular features, such as LOH18q and TP53 mutation analysis, have shown promising results in terms of their prognostic value, the American Society of Clinical Oncology Tumor Markers Expert Panel does not currently recommend their use in routine practice. cDNA-microarray, PCR and fluorescence in situ hybridisation are now frequently used to identity potential prognostic indicators in CRC, but the applicability of these methods in routine use is likely to have limited impact. Reliable ...
For preoperative rectal cancer T (tumor) staging, ERUS is more accurate than CT; ERUS is less likely than CT to incorrectly stage (odds ratio [OR] = 0.36; 95% confidence interval [CI], 0.24 to 0.54), less likely to understage (OR = 0.63; 95% CI, 0.44 to 0.89), and less likely to overstage (OR = 0.47; 95% CI, 0.28 to 0.80), supported by evidence of low strength. For preoperative rectal cancer T staging, MRI and ERUS were similar in accuracy, supported by evidence of low strength. There was no statistical difference in accuracy between MRI and CT, but there were few patients in the available studies. For preoperative rectal cancer N (lymph node) staging, CT, MRI, and ERUS were similar in overall accuracy, but all three modalities had limited sensitivity. MRI was less likely to overstage preoperative rectal cancer N stage than CT (OR = 0.498; 95% CI, 0.308 to 0.806), supported by evidence of low strength. We identified only one study of preoperative T and N staging of colorectal cancer using CT ...
Gastric carcinoma (GC) is one of the most common causes of cancer-related death worldwide. Surgical resection is the only cure available and is dependent on the GC stage at presentation, which incorporates depth of tumor invasion, extent of lymph node and distant metastases. Accurate preoperative staging is therefore essential for optimal surgical management with consideration of preoperative and/or postoperative chemotherapy. Multidetector computed tomography (MDCT) with its ability to assess tumor depth, nodal disease and metastases is the preferred technique for staging GC. Endoscopic ultrasonography is more accurate for assessing the depth of wall invasion in early cancer, but is limited in the assessment of advanced local or stenotic cancer and detection of distant metastases. Magnetic resonance imaging (MRI), although useful for staging, is not proven to be effective. Positron emission tomography (PET) is most useful for detecting and characterizing distant metastases. Both MDCT and PET ...
BACKGROUND The American Joint Committee on Cancers (AJCC) 7th edition cancer staging manual reflects recent changes in cancer care practices. This report assesses changes from the AJCC 6th to the AJCC 7th edition stage distributions and the quality of site-specific factors (SSFs). METHODS Incidence data for renal parenchyma and pelvis and ureter cancers from 18 Surveillance, Epidemiology, and End Results (SEER) registries were examined, including staging trends during 2004-2010, stage distribution changes between the AJCC 6th and 7th editions, and SSF completeness for cases diagnosed in 2010. RESULTS From 2004 to 2010, the percentage of stage I renal parenchyma cancers increased from 50% to 58%, whereas stage IV and unknown stage cases decreased (18% to 15%, and 10% to 6%, respectively). During this period, the percentage of stage 0a renal pelvis and ureter cancers increased from 21% to 25%, and stage IV and unknown stage tumors decreased (20% to 18%, and 7% to 5%, respectively). Stage ...
From a clinical perspective, although T2 stage cancer is not an indication for CCRT in the National Comprehensive Cancer Networkguidelines [2-6], some patients with T2 stage cancers undergo CCRT. CCRT was associated with a high pCR rate in some studies, including in our study. Therefore, CCRT may be suitable for selected patients who require analsparing procedures. A major factor in selecting CCRT for T2 stage cancer is precise T staging using appropriate imaging modalities, and this attempts to predict pCR. A long interval between finishing CCRT and surgery was a significant predictive factor in the multivariate analysis in our study. Thus, the timing of surgery is important. Some studies reported the interval between CCRT and surgery [25,26], in which the interval ranged from 4 to 8 weeks. Based on the findings of these studies, all patients could undergo complete resection without an increased rate of postoperative complications. According to these results, an interval of 4-8 weeks from ...

CDC has created software in the form of a dynamic link library (DLL) to help cancer registries collect data on stage of disease for cancers according to the TNM system of the American Joint Committee on Cancer (AJCC).
Prognostication in UM usually entails the incorporation of clinical, histomorphological, and genetic parameters.3,4 The latter information may not be available in all ocular centers and hence prognostication for patients with UM is based predominantly on the American Joint Committee on Cancer (AJCC)/ tumor size, lymph nodes affected, and metastases (TNM) staging system (i.e. on clinical, anatomic, and morphologic parameters),31 However, direct manual analysis of digital histopathological images has proven feasible and efficient to predict and detect the related gene status of tumor cells, as a potential surrogate to both IHC and genetic testing.14 This, however, requires a large number of hours of repetitive work by pathologists, annotating slides to determine the ground truth.32,33 In recent years, there has been an appetite to apply AI-related techniques, especially DL, for the automated analysis of digital histopathology images. Data-driven approaches have resulted in an improvement in DL ...
Staging enables your doctor to develop the best treatment plan for your diagnosis. Along with considering the results of your physical exam, imaging studies and laboratory tests, your doctor will classify and stage the breast cancer according to the tumor, node and metastasis (TNM) system developed by the American Joint Committee on Cancer (AJCC).. In this system, the tumor (T) is categorized according to its size and location; the node (N) category describes whether cancer cells are found in lymph nodes; and the metastasis (M) category indicates whether the cancer has metastasized, or spread, to other parts of the body, such as the bones, brain, liver or lungs (see Table 1). The stage is described by Roman numerals from 0 to IV and the letters A, B or C, if applicable (see Table 2).. Breast cancer is also classified into subtypes based on molecular or genetic changes. Identifying the subtype is important because treatments and monitoring milestones, such as the length of time without ...

In staging cancer, your doctor determines the extent of the cancer based on the size of the tumor and whether the cancer has spread and, if so, how far.. Endometrial cancer is often staged based on the surgical removal of the tumor. To establish whether the cancer cells have spread, the surgeon may also remove nearby lymph nodes, tissues and fluid within the pelvic and/or abdominal cavity. A pathologists examination of these samples and information from imaging tests help the doctor determine an accurate and exact stage, which is the most important factor in choosing an appropriate treatment option.. Like many other cancer types, endometrial cancer is classified according to the tumor, node, metastasis (TNM) system developed by the American Joint Committee on Cancer (AJCC). The tumor (T) is analyzed and categorized based on its size and location, whether cancer ...

The widespread use of the TNM staging system has helped standardize the classification of cancers. Despite its excellence in describing a tumors size and extent of anatomic spread, the TNM system does not account for the clinical biology of the cancer.
Stage is a key predictor of cancer survival. Complete cancer staging is vital for understanding outcomes at population level and monitoring the efficacy of early diagnosis initiatives. Cancer registries usually collect details of the disease extent but staging information may be missing because a stage was never assigned to a patient or because it was not included in cancer registration records. Missing stage information introduce methodological difficulties for analysis and interpretation of results. We describe the associations between missing stage and socio-demographic and clinical characteristics of patients diagnosed with colon, lung or breast cancer in England in 2013. We assess how these associations change when completeness is high, and administrative issues are assumed to be minimal. We estimate the amount of avoidable missing stage data if high levels of completeness reached by some Clinical Commissioning Groups (CCGs), were achieved nationally. Individual cancer records were retrieved from

When the glands are enlarged by secondary growth, as is sometimes obvious, the ultimate prognosis is adversely affected, even when all visible glands are removed.1. Perhaps the most important advances in the evaluation of patients with lung cancer have come from better ability to stage patients accurately. The staging classification is extremely important because the correct stage provides both prognostic information and a framework for ...

Once your doctor has diagnosed cancer, it important to find out how big the cancer is and where it started to grow. They need to see if the cancer has spread to the lymph nodes in the neck (nodal metastases) or other parts of the body such as the lungs, liver or bone (distant metastases). The term used to describe where the cancer has started to grow is called primary and if it spreads to other parts of the body, it is called a secondary or metastases. This is called staging. Staging a cancer is important because it helps your doctor to choose the best treatment for you.. ...

Full Text - Purpose: This study aimed to validate the newly proposed American Joint Committee on Cancer (AJCC) pathological prognostic staging system for young breast cancer patients (aged ≤40 years).Results: We included 12811 women in this study. Overall, 52.8% of patients in the 7th AJCC stages were restaged to the 8th AJCC pathological staging system, including 10.7% upstaged and 42.1% downstaged. The receiver operating characteristics analysis showed that the new staging system had a better role in predicting breast cancer-specific survival (BCSS) compared with 7th edition staging (P<0.001). The results of the multivariate prognostic analysis showed that the hazard ratio of BCSS increased with the 8th AJCC stages, while the 7th anatomic stages had no significant difference in BCSS.Conclusions: The novel pathological staging system could provide more accurate prognostic stratification for young women with breast cancer because of the high proportion of stage migration.Patients and Methods:

BACKGROUND: Identification of high-risk stage II colorectal cancer (CRC) patients, potential candidates for adjuvant chemotherapy, is challenging. Current clinical guidelines rely mainly on histopathological markers with relatively weak prognostic value. This motivates further search for prognostic markers.. METHODS: This explorative study aimed to identify potential candidate gene mutations to facilitate differentiation between subgroups of patients with CRC stage II. Panel-based massive parallel sequencing was used to genetically characterize tumor tissues from 85 patients radically operated for CRC stage II, of which 12 developed recurrent cancer during follow-up. Genetic data was compared between patients with or without cancer recurrence, between tumors located in colon and in rectum, and for association with tumor differentiation grade.. RESULTS: Genetic variation in ATM, C11ORF65 was associated with recurrence-free survival. Previous reports regarding the association between BRAF mutation ...
After integrating MPV and PDW/PCT into the multivariable Cox model, we developed a new prognostic model and a novel staging system. The OS of patients belonging to different stages were significantly different, either limited to specific types of BTC or the entire BTC cohort. Meanwhile, the AJCC 7th TNM staging system presented modest prognostic power in patients with ECC (Fig. 3H), and has been shown to have poor prognostic performance in several subsets of patients with BTC [25]. The C-index of our novel prognostic model was 0.703 in the training cohort and 0.728 in the validation cohort. Compared to the AJCC TNM stage, with a C-index of 0.561 and 0.618, our prognostic model has superior discrimination to the AJCC TNM stage. DCA also implied increased clinical benefits with the utility of our new staging system. Based on these results, we can conclude that our new prognostic model outperformed the AJCC TNM staging system in many aspects. An obvious advantage of our new prognostic model is the ...
Neoadjuvant chemoradiation decreases the risk of local recurrence in locally advanced rectal cancer and is therefore indicated by guidelines in patients with positive nodal status (cN+) or cT3/4 tumors. On the other hand is neoadjuvant chemoradiation associated with relevant side effects and long term complications such as loss of sexual activity and fecal incontinence. However, accuracy of routine pretherapeutic lymph node staging (cN) in rectal cancer with MR imaging is still limited which can lead to overstaging and overtreatment. Few studies have shown a distinct improvement of the diagnostic accuracy of nodal staging (cN) by applying morphologic criteria (altered border contour and inhomogeneous signal intensity) instead of the established size criterion. The aim of the study was to determine and compare accuracy, sensitivity and specificity of the size criterion and morphological criteria in nodal staging. LN in preoperative MRI of 60 patients with rectal cancer and primary surgery that ...
INTRODUCTION] An accurate preoperative rectal cancer staging is crucial to the correct management of the disease. Despite great controversy around this issue, pelvic magnetic resonance (RM) is said to be the imagiologic standard modality. This work aimed to evaluate magnetic resonance accuracy in preoperative rectal cancer staging comparing with the anatomopathological results. METHODS We calculated sensibility, specificity, positive (VP positive) and negative (VP negative) predictive values for each T and N. We evaluated the concordance between both methods of staging using the Cohen weighted K (Kw), and through ROC curves, we evaluated magnetic resonance accuracy in rectal cancer staging. RESULTS 41 patients met the inclusion criteria. We achieved an efficacy of 43.9% for T and 61% for N staging. The respective sensibility, specificity, positive and negative predictive values are 33.3%, 94.7%, 33.3% and 94.7% for T1; 62.5%, 32%, 37.0% and 57.1% for T2; 31.8%, 79%, 63.6% and 50% for T3 and ...

Breast cancer stage 3 describes the breast cancer has extend to the underarm lymph nodes and muscles but not spread to more distant sites in the body. This stage is divided into three groups, breast cancer stage 3A, 3B and 3C.
Surgery and radiotherapy may not be suitable for most breast cancer stage 4 patients. Here are the suggested treatment options for patients with breast cancer stage 4.
Stage III breast cancer requires local therapy such as surgery and/or radiation and systemic therapy such as chemotherapy, hormonal or biological therapy.
Colorectal cancer (CRC) is the third most frequently diagnosed cancer, and second leading cause of cancer-related deaths in the United States (1). Current prognosis for patients with CRC predominantly relies on pathologic Unio Internationale Contra Cancrum/American Joint Committee on Cancer (UICC/AJCC) tumor-node-metastasis (TNM) staging classification (2). Although TNM staging successfully stratifies high-risk patients, there is significant variability in the rate of disease progression within each stage. Particular concern exists for early-stage disease (stage I and II) where patients can progress more rapidly than expected. It is well known that approximately 30% of patients with stage II CRC die of recurrent and metastatic disease. Identification of patients at risk of recurrence/progression could inform clinicians on adjuvant chemotherapeutic treatment decisions. Biomarkers can assist in identifying those patients who require more aggressive intervention or patients at risk of relapse after ...
Individualized approaches to prognosis are crucial to effective management of cancer patients. We developed a methodology to assign individualized 5-year disease-specific death probabilities to 1,222 patients with melanoma and to 1,225 patients with breast cancer. For each cancer, three risk subgroups were identified by stratifying patients according to initial stage, and prediction probabilities were generated based on the factors most closely related to 5-year disease-specific death. Separate subgroup probabilities were merged to form a single composite index, and its predictive efficacy was assessed by several measures, including the area (AUC) under its receiver operating characteristic (ROC) curve. The patient-centered methodology achieved an AUC of 0.867 in the prediction of 5-year disease-specific death, compared with 0.787 using the AJCC staging classification alone. When applied to breast cancer patients, it achieved an AUC of 0.907, compared with 0.802 using the AJCC staging classification
We compared the prognostic value of the American Joint Committee on Cancer (AJCC) TNM nodal staging system with that of lymph node (LN) density in patients with

The most common staging system is the TNM (for tumors/nodes/metastases) system, from the American Joint Committee on Cancer (AJCC). The TNM system assigns a number based on three categories. T denotes the degree of invasion of the intestinal wall, N the degree of lymphatic node involvement, and M the degree of metastasis. Possibly, the The overall AJCC stage is a shorter format of the TNM stage, and is usually quoted as a number I, II, III, IV derived from the TNM value grouped by prognosis; a higher number indicates a more advanced cancer and likely a worse outcome. Following is the eighth edition from 2017: ...
Background Staging investigations for metastatic disease are not recommended for asymptomatic patients with early breast cancer. However, it is relatively common practice to perform staging in patients who are heavily node positive (4 or more nodes involved). This study explored the benefit of routine investigations in this patient group.. Methodology All patients operated in Castle Hill Hospital, Hull, UK between January 2005 and December 2011 for early breast cancer and found to have 4 or more nodes involved on pathological assessment were identified. Staging investigations, consisting of CT chest, abdomen and pelvis and isotope bone scan, were reviewed. The need for additional investigations was recorded.. Results A total of 231 patients were identified. 59 patients were excluded as no staging investigations were performed. In the remaining 172 patients staging investigations were positive in 12% (21/172). An additional 17% (29/172) required further investigations for equivocal scans and were ...
A recent study published in the journal Cancer last month compared the survival of 8,988 kidney cancer patients from the American National Cancer Data Base to assess the impact of cancer spread to the lymph nodes in patients with stage III renal cell carcinoma (RCC).. The researchers found that the 5-year survival rate of patients with cancer spread to their lymph nodes (lymph node-positive stage III disease) was 23% and was more like that of patients with stage IV disease (16%) than patients with lymph node-negative stage III disease (62%).. This study may help to explain the lack of survival benefit with adjuvant therapy in patients with stage III RCC and positive lymph nodes, particularly adjuvant therapy with TKIs (e.g. the ASSURE trial). Also, it may help to explain outcomes in stage III patients who have surgical removal of their positive lymph nodes and survival similar to that of patients with stage IV disease.. In conclusion, the results from this study support the finding that patients ...

Endoscopic ultrasonography (EUS) is the single best modality for staging esophageal cancer with respect to depth of tumor infiltration and extent of lymph node involvement using the TNM classification system. The accuracy of EUS for staging patients with esophageal carcinoma who subsequently underwent surgery for confirmation ranged from 59% to 92% (with a mean of 84% in 1154 patients); the accuracy for N staging ranged from 50% to 90% (with a mean of 77% in 1035 patients). Endosonography is superior to CT in the T and N staging of disease. However, EUS is not a sensitive tool for diagnosing tumor involvement of the trachea and bronchial tree, because these structures contain air. Bronchoscopy should be used for the staging of proximal esophageal cancers. If esophageal cancers obstruct the lumen and the EUS endoscope cannot be advanced through, tumor staging is incomplete. EUS employs the technology of endoscopy and internally placed high-frequency ultrasound waves to visualize the ...
In addition, the prognosis of our patients with EUS non-traversable EC may have been further worsened by the limited EUS assessment of EC stage. EUS is a standard locoregional staging modality for EC, demonstrating high T (80% to 90%) and N staging accuracy (70% to 80%) that is clearly superior to CT and magnetic resonance imaging [3,4]. However, the accuracy of EUS decreases significantly when an echoendoscope cannot pass through EC. Staging accuracy of EUS is reportedly 46% in EUS non-traversable EC (vs. 92% in EUS traversable EC) and correct preoperative T stage was obtained using EUS only in 30.8% of patients with high-grade EC stenosis (vs. 81% of patients with less severe EC stenosis) [6,22]. A previous study reported that 9.9% of patients with distant metastatic nodes were found on EUS after EC stenosis dilation [23]. Another study on the effects of EUS after dilation of EC stenosis reported that EUS detected additional cases of advanced diseases in 19% of patients, including celiac node ...

Breast cancer stages help determine your treatment. In general, the earlier the stage of breast cancer, the better the prognosis will be.
Despite undergoing complete surgical removal of the cancer, 25-40% of patients with Stage II colon carcinoma experience recurrence of their cancer.
Although the most important prognostic and predictive marker in colorectal cancer is tumor cells in lymph nodes, ∼30% of patients who are node-negative die from occult metastases. Molecular staging employing specific markers and sensitive detection technologies has emerged as a powerful platform to assess prognosis in node-negative colon cancer. Integrating molecular staging into algorithms that individualize patient management will require validation and the definition of relationships between occult tumor cells, prognosis, and responses to chemotherapy.

Till 2002, the revisions of the TNM classification were based on the analyses of a database that included over 5,000 patients, and that was managed by Clifton Mountain. These patients originated from North America and almost all of them had undergone surgical treatment. To overcome these limitations, the International Association for the Study of Lung Cancer proposed the creation of an international database of lung ...

Introduction Previous studies showed that TNM stages that were clinically determined before surgery were not often concordant with pathological TNM stages. However, no previous studies have examined variations of discordance of the clinical TNM stage with the pathological TNM stage among hospitals. We aimed to examine the discordance of the clinical and pathological stages among Japanese designated cancer hospitals using compiled data from the hospital-based cancer registry submitted from 286 designated cancer care hospitals in Japan.. Methods The registry data had UICC TNM stages before and after surgery for stomach, colorectal, lung and breast cancer patients treated in these hospitals. We excluded patients who received adjuvant chemotherapy or radiotherapy, patients who received care from facilities with less than 10 patients, male breast cancer and patients whose stages were unknown from the analysis. We also calculated discordance of stages that could have theoretically resulted in changes ...
