Introduction To measure the radiation exposure to the surgeon during axillary sentinel lymph node biopsy using the radioactive isotope technetium-99m. Method A prospective analysis of 36 patients undergoing axillary sentinel lymph node biopsy using technetium-99m, between 15th January 2013 to the 20th February 2013.. Results The exposure to the surgeon during axillary sentinel lymph node dissection was measured in 36 patients by placing a thermoluminescent dosimeter (TLD) on the surgeons finger. The TLDs recorded the total radiation exposure to the surgeon. The recommended occupational dose limit for non radiation workers extremity exposure is less than 500 μSv. The analysed and extrapolated data showed an average exposure dose to the surgeon per patient of 2.7 μSv. Conclusion One surgeon would need to perform more than 85 such procedures per year in order to exceed the advised annual extremity dose limit. The data also suggests that regular measurements of radiation exposure and radiation ...
The purpose of this study was to investigate potential risk factors for failed sentinel lymph node identification in breast cancer surgery. Patient characteristics, tumour characteristics, surgeon experience and detection success/failure were registered at 748 sentinel lymph node biopsy procedures at our inpatient clinic. Data were analysed with backward stepwise multiple logistic regression with a cut-off point of p,0.05. We found that increased age, increased BMI, medial tumour location and less surgeon experience independently were associated with a lower sentinel lymph node detection rate. Tumour size, palpability and biopsy method were not significantly associated with the sentinel lymph node detection rate. In conclusion, it is possible to identify patients with a higher risk of sentinel lymph node identification failure and we recommend that these patients are operated by experienced surgeons in order to avoid accumulation of independent risk factors in individual cases. ...

A sentinel lymph node biopsy is the removal and testing of specific lymph node tissue. A sentinel lymph node biopsy is often done during cancer-removal surgery or prior to surgery. The sentinal nodes are the lymph nodes to which cancer would spread first. Sentinel node biopsy is part of the staging process. Staging is an attempt to determine how much the cancer has spread away from the original tumor.

ISSN 2078-5151. http://dx.doi.org/10.7196/SAJS.1357.. OBJECTIVES/HYPOTHESIS: The objective of the study was to determine whether sentinel lymph node biopsy (SLNB) can be used to reduce clinical overstaging of cervical nodes in head and neck squamous cell carcinoma (SCC) in a developing world setting. STUDY DESIGN: Sentinel and echelon lymph nodes were identified by means of a combination of lymphoscintigraphy, gamma probe and blue dye staining. They were analysed histologically and their pathological status was compared with the rest of the neck dissection specimen to determine diagnostic accuracy in patients with T1-4 N0-3 SCC of the oral cavity or oropharynx undergoing primary surgical resection and neck dissection. RESULTS: Thirty-three patients were included in the study, 13 in the node-negative (N0) and ...
Considering the high diagnostic accuracy and less vulnerable staging and therapy procedures, SLNB has rapidly become the state of the art diagnostic for axillary staging in early breast cancer.. Prior surgery, the so called sentinel lymph nodes are detected, harvested and histopathologically examined. The histopathologic status of the sentinel node thereby accurately reflects the status of the remaining axillary nodes. The sentinel lymph node biopsy allows minimizing risks and burdens for patients who very likely have no metastasis in the axillary lymph nodes sparing the ALND and reducing the risk of surgery and postoperative lymph oedema for instance. Contrarily to former procedure where an axillary lymph node dissection (ALND) was done each time, an ALND now only follows if the detected sentinel lymph node is metastatic.. Routinely sentinel lymph nodes are mapped using radiocolloid tracers such as technetium, sometimes combined with a blue dye.. However the infrastructure for a radioactive ...

Objective:. The role of axillary staging and natural history in microinvasive breast cancer (MIC) is not well known. This study assesses outcome in patients with ductal carcinoma in situ (DCIS) with microinvasion who did not undergo sentinel lymph node biopsy (SNB).. Methods:. A retrospective analysis of DCIS with microinvasion (DCISM) patients surgically treated at the Asan Medical Center from March, 2003 to December, 2009 was conducted. Bilateral breast cancer patients and patients who underwent node dissection were excluded from the study. SNB was performed in most of DCIS patients after surgery when microinvasion was found, but in some patients with clinically negative axillary lymph node metastasis, SNB was omitted.. Results:. A total of 185 consecutive patients with DCISM were identified. Thirty-three patients did not undergo SNB [SNB(-) group], while 152 patients did [SNB(+) group]. No recurrence occurred in the SNB(-) group during a median follow-up period of 63.5 months, while one ...

BACKGROUND: Sentinel lymph node biopsy in women with operable breast cancer is routinely used in some countries for staging the axilla despite limited data from randomized trials on morbidity and mortality outcomes. We conducted a multicenter randomized trial to compare quality-of-life outcomes between patients with clinically node-negative invasive breast cancer who received sentinel lymph node biopsy and patients who received standard axillary treatment. METHODS: The primary outcome measures were arm and shoulder morbidity and quality of life. From November 1999 to October 2003, 1031 patients were randomly assigned to undergo sentinel lymph node biopsy (n = 515) or standard axillary surgery (n = 516). Patients with sentinel lymph node metastases proceeded to delayed axillary clearance or received axillary radiotherapy (depending on the protocol at the treating institution). Intention-to-treat analyses of data at 1, 3, 6, and 12 months after surgery are presented. All statistical tests were ...
... is performed to assess whether there is any spread of breast cancer into the axilla. The technique is usually performed in conjunction with lumpectomy or mastectomy. Prior to surgery, an injection of dye (a radioactive isotope) is performed in the X-Ray Department. The dye is injected around the tumour and/or under the nipple. This dye is taken up into the lymphatic system and allows mapping of the lymphatic drainage of the breast. This is usually into the lymph nodes under the armpit (axilla) but may occasionally be toward the midline, between the ribs. It may take up to three hours to map which lymph nodes drain from the tumour site. The skin is usually marked over the lymph nodes of interest. During the surgical procedure, blue dye is also injected around the tumour to map out the lymphatic drainage in a similar fashion. At operation, an incision is made over the lymph node, which would most often be in the axilla. A small transverse incision , approximately 3 to 5 ...

Cervical adenopathy in patients with squamous cell carcinoma (SCC) of the upper aerodigestive tract is assumed to represent nodal metastasis and is treated with therapeutic neck dissection.[1] Overstaging of the neck leads to overtreatment by modified neck dissection. In southern Africa and the developing world, the accuracy of clinical staging of cervical adenopathy in head and neck cancer may be confounded by the high prevalence of other causes of lymphadenopathy such as HIV, tuberculosis and untreated upper respiratory and dental infections. De Waal et al. reported a false-positive rate of 32% for the clinically node-positive (N+) neck when comparing clinical staging with pathological analysis in a study done in Cape Town.[2]. Sentinel lymph node biopsy (SLNB) has been employed for the node-negative (N0) neck to avoid unnecessary elective neck dissection (END).[1,3-6] However, no studies have been reported on the use of SLNB to distinguish between inflammatory and metastatic adenopathy in the ...

The sentinel lymph nodes (SLN) are the first lymph nodes to drain the tumor site and therefore the first lymph nodes to bare metastases. Hence the importance to investigate these lymph nodes to define the best treatment strategy. Currently in a.o. breast cancer and melanoma patients, the sentinel lymph nodes are intraoperatively detected, both visually and by using a gamma probe, following the subsequent injections of radioactive tracer (Tc 99-m) and blue dye (Patent Blue). Histopathological investigation of the resected sentinel lymph nodes should then confirm the presence or absence of metastases. The conventional methods for sentinel lymph node biopsy suffer from disadvantages, such as the use of radioactive materials and the fact that node-positive patients require multiple surgical procedures. At the NeuroImaging (NIM) group of the University of Twente, we investigate a magnetic, radiation-free, procedure for sentinel lymph node detection and evaluation. Several aspects of this procedure ...
Introduction To decipher the interaction between the molecular subtype classification and the probability of a non-sentinel node metastasis in breast cancer patients with a metastatic sentinel lymph-node, we applied two validated predictors (Tenon Score and MSKCC Nomogram) on two large independent datasets. Materials and Methods Our datasets consisted of 656 and 574 early-stage breast cancer patients with a metastatic sentinel lymph-node biopsy treated at first by surgery. We applied both predictors on the whole dataset and on each molecular immune-phenotype subgroups. The performances of the two predictors were analyzed in terms of discrimination and calibration. Probability of non-sentinel lymph node metastasis was detailed for each molecular subtype. Results Similar results were obtained with both predictors. We showed that the performance in terms of discrimination was as expected in ER Positive HER2 negative subgroup in both datasets (MSKCC AUC Dataset 1 = 0.73 [0.69-0.78], MSKCC AUC Dataset 2
A lymph node biopsy occurring more than 30 days after diagnosis is unlikely to have an adverse effect on the patients overall prognosis. Postponing lymph node biopsy more than 30 days after melanoma diagnosis doesnt adversely impact long-term clinical outcomes according to new study findings published in the Journal of the American College of Surgeons website ahead of print publication.. Every year, about 87,000 people are diagnosed with melanoma, according to the American Cancer Society.* This most severe form of skin cancer is almost entirely curable if caught before it spreads to nearby (sentinel) lymph nodes.. Today, management of high-risk melanomas starts with surgical removal of the layers of skin cancer and a lymph node biopsy, a procedure in which a tissue sample is sent to a lab to check for cancerous cells. Patients with a positive sentinel node biopsy may undergo complete lymph node dissection to lower the risk of recurrence.. In theory, postponing biopsy after a melanoma diagnosis ...
ANN ARBOR, MI - A common technique for determining whether melanoma has spread can be used safely and effectively even in tumors from the head and neck area, according to a new study from the University of Michigan Comprehensive Cancer Center.. Sentinel lymph node biopsy involves injecting a special dye to identify the first node where cancer would likely spread. If that node is clean, patients can avoid further debilitating surgery to remove multiple lymph nodes. If that node shows cancer, patients know they need the more extensive surgery or further treatment with radiation, chemotherapy or a clinical trial. Patients with larger melanomas are routinely offered this procedure.. But many surgeons believed that the complex anatomy combined with the critical nerves and blood vessels in the head and neck area made sentinel lymph node biopsy unsafe and inaccurate for melanomas in that region.. In the current study, which appears online in Cancer, researchers looked at 353 head and neck melanoma ...
Sentinel lymph node (SLN) biopsy has been used to assess patients with papillary thyroid carcinoma (PTC). To achieve its full potential the rate of SLN identification must be as close to 100 percent as possible. In the present study we compared the c
Squamous cell carcinoma (SCC) of the oral cavity is an aggressive malignancy with a tendency to spread to lymph nodes (LNs) in the neck. Accurate detection of positive cervical LNs is critical because this regional involvement is associated with a 50% decrease in survival. The overall rate of occult LN metastases in oral SCC is 24.8%, and as such, neck dissection is the gold standard for both staging and treating this disease. Sentinel lymph node biopsy (SLNB) is an alternative to neck dissection to identify occult cervical metastases, and is currently performed using a combination of a handheld gamma probe and nuclear lymphoscintigraphy after interstitial administration of radiotracers around the primary tumour. While this is practiced commonly in the management of breast cancer and melanoma, its adoption for oral cancer has been limited due to poor accuracy of this technique in this anatomical area relating to a lack of spatial resolution and a shine through effect between the floor of the ...

Melanoma is unique among skin cancers in that it can spread anywhere in the body," Dr. Wray says. "Its thickness is a very important prognostic factor and determines whether we need to do a sentinel lymph node biopsy. If the lymph node biopsy is positive, it can significantly affect survival.". In a surgery performed under general anesthesia at Memorial Hermann-Texas Medical Center, Dr. Wray removed the spots with a wide local excision. He sent Jay for a sentinel lymph node biopsy, the removal of one or two lymph nodes from each arm. The pathology report came back negative. Because of the small number of lymph nodes removed, he was not at risk for lymphedema, which can cause swelling and pain, usually in the arms, and require rehabilitative treatment.. "Everything about the process was impressive," Jay says. "My professional career has led me to become an operations expert. My role has always been to make a process better, but I couldnt find any way to improve on my experience. I was really ...
Once the presence of melanoma is confirmed, your doctor may wish to perform other tests especially if you have symptoms. Other tests may also be recommended if your doctor is concerned the melanoma has spread.. Sentinel Node Biopsy. After a diagnosis your doctor will need to determine whether or not the melanoma has spread beyond the primary tumour or local tissues. If so, it may have spread to the lymphatic system. The lymphatic system is a network of vessels that carry lymph through your body and melanoma may be found in the regional draining lymph nodes near the tumour.. The sentinel lymph node is the first lymph node to which cancer is likely to spread from a primary tumor. A sentinel lymph node biopsy is performed to confirm there are no signs of spread. A radioactive tracer dye is injected and followed to the sentinel lymph node, which is generally located in one of the major lymph node basins - inguinal, etc.. If the node does not contain melanoma, then the adjacent nodes are unlikely to ...

The main objective of the trial is to prove equivalent local/regional control for patients with proven axillary lymph node metastasis by sentinel node biopsy if treated with axillary radiotherapy instead of axillary lymph node dissection, with reduced morbidity. A second objective is to investigate whether adequate axillary control can be obtained by not subjecting patients with a negative sentinel lymph node to ALND.. As of 1 May, 18 institutes have included 1173 patients. It is assumed that the axillary recurrence-free rate in the ALND treatment group at 5 years equals 98%, and the aim of this study is to show that the axillary recurrence-free rate in the radiotherapy group at 5 years is not less than 96%. Given the ratio of 40 positive patients/60 negative patients, a total of 3485 patients are required to complete this study. The ratio to date of 35/63 (taking into account a 2% nonidentification rate) leads to a slight adjustment of the total number of patients needed. The study will at ...
Background Near-infrared (NIR) fluorescent sentinel lymph node (SLN) mapping in breast cancer requires optimized imaging systems and lymphatic tracers.
The most important prognostic factor in breast cancer is the axillary lymph node status. The sentinel node biopsy (SNB) is reported to stage the axilla with an accuracy , 95 % in early breast cancer. Tumour-related perturbation of T-cell function has been observed in patients with malignancies, including breast cancer. The down-regulation of the important T-cell activation molecules CD3-ζ and CD28 may cause T-cell dysfunction, anergy, tolerance and deletion.. The expression of CD3-ζ and CD28 was evaluated in 25 sentinel node biopsies. The most pronounced down-regulation was seen in the paracortical area, where the best agreement between both parameters was observed. CD28 expression was significantly more suppressed in CD4+ than in CD8+ T-cells.. From the Swedish sentinel node database, 109 patients with breast cancer , 3 cm planned for both SNB and a subsequent axillary dissection were identified. The false negative rate (FNR) was 12.5%. Thirteen cases of tumour multifocality were detected on ...
Sentinel node mapping is a procedure that is carried out pre-surgery, usually on the day of surgery, but sometimes the day before surgery. Standard practice for breast cancer surgery is to remove all of the lymph nodes under the arm to find out if the cancer has spread beyond the breast. However, removing all the…
Background: Sentinel lymph node (SLN) biopsy has replaced axillary lymph node dissection as the routine staging procedure in clinically node-negative breast cancer. False-negative SLN biopsy results in misclassification and may cause undertreatment of the disease. The aim of this study was to investigate whether serial sectioning of SLNs reveals metastases more frequently in patients with false-negative SLNs than in patients with true-negative SLNs. Methods: This was a case-control study. Tissue blocks from patients with false-negative SLNs, defined as tumour-positive lymph nodes excised at completion axillary dissection or a subsequent axillary tumour recurrence, were reassessed by serial sectioning and immunohistochemical staining. For each false-negative node, two true-negative SLN biopsies were analysed. Tumour and node characteristics in patients with false-negative SLNs were compared with those in patients with a positive SLN by univariable and multivariable regression analysis. Results: ...

For breast cancer patients with a sentinel lymph node that appears free of cancer based on standard testing (hematoxylin-eosin staining), detection of very small areas of cancer in the lymph node through additional, more sensitive testing (immunohistochemistry) does not affect breast cancer outcomes. Standard testing of the sentinel node, therefore, appears to be sufficient. These results were published in the Journal of the American Medical Association.. For women with early breast cancer, determining whether the cancer has spread to the axillary (under the arm) lymph nodes is an important part of cancer staging. Many women initially undergo a sentinel lymph node biopsy, in which only a small number of nodes (or even a single node) is removed. If the sentinel nodes show evidence of cancer, many women then undergo additional lymph node removal.. In some cases, cancer in the lymph nodes may be too small to detect through standard procedures, but possible to detect through additional, very ...
