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 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 ...
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 ...

Radiological examination should never be omitted, but it must be recognized that a carcinoma can occur in one of the larger bronchi without any radiological change in the lung, provided there is insufficient obstruction to interfere with the free inflow and outflow of air to and from the lung beyond. In the majority of cases, however, a shadow will be evident on the film… Enlarged glands are almost invariably present, and it is by no means always easy to determine whether the enlargement is due to infection, secondary growth, or a combination of both. 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.

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:
Whether to perform primary tumor resection in patients with asymptomatic Stage IV colorectal cancer remains controversial; however, the more aggressively we perform radical resection and metastasectomy to selected patients, the more survival benefits the patients obtain.
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

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 ...
Staging is how physicians determine the extent of your cancer, where it is located, and whether it has metastasized to nearby organs or tissue or to other parts of your body.. The TNM staging system, developed by the American Joint Committee on Cancer (AJCC), is typically used to stage head and neck cancers. This system classifies the cancer by tumor (T), node (N) and metastasis (M). The T category describes the size and location of the primary tumor. The N category describes lymph node involvement, indicating whether the lymph nodes show evidence of cancer cells. The location of these lymph nodes is important because it shows how far the disease has spread. The pathologic N category (sometimes denoted as pN) describes how many lymph nodes are involved and the amount of tumor cells found in the nodes. The M category describes distant metastasis (spread of cancer to another part of the body), if any. Staging for the M category is mainly clinical; however, a new M subcategory may be given based on ...
