This is characterized by thicker lesions at diagnosis, which are hallmarked by bleeding, itching, ulceration, and increased vertical growth. In a study of 1,626 cutaneous melanoma patients at the H. Lee Moffitt Cancer Center in Florida, three prognostic factors, tumor thickness, Clark level, and presence of ulceration in the primary tumor, have remained relatively constant over an eight-year period (1987-1994). Despite the lack of change in tumor thickness in the last four years, mortality rate is decreasing, possibly due to more effective treatments. Regardless of these apparent improvements in mortality rates, definite progress must be made in the early detection of malignant melanoma through the initiation of statewide programs of lay public and professional education.

Defined patterns of lymphatic drainage allow intra-operative determination of the first (sentinel) lymph node in the regional basin, and the absence of metastatic disease in the SLN accurately reflects the absence of melanoma in the remaining regional nodes. The use of a radiocolloid and a handheld gamma probe together with a vital blue dye provides optimal results, and allows for the successful identification of the SLN(s) in over 98 percent of the procedures. Close collaboration between surgeons, nuclear radiologists and pathologists is required to ensure optimal results. Surgical excision of the SLN allows for a more thorough and focused pathological examination of one or two nodes. Examination of serially sectioned SLNs by H&E staining, immunohistochemical staining and perhaps RT-PCR should reduce the number of patients with missed microscopic melanoma in the regional lymph nodes. Recently reported survival data from the Intergroup Melanoma Trial suggest that patients may benefit from identification and removal of regional lymph nodes that contain metastatic melanoma. Furthermore, the survival benefit recently reported in patients with melanoma metastatic to regional nodes prospectively randomized to receive high dose Interferon alfa-2b signals that the surgeons should aggressively examine patients for the presence of occult regional melanoma metastases. Intra-operative SLN mapping and SLN biopsy is a cost-effective procedure that allows accurate identification of regional lymph nodes that contain metastatic melanoma.</p>","PeriodicalId":76670,"journal":{"name":"The Journal of the Florida Medical Association","volume":"84 3","pages":"188-93"},"PeriodicalIF":0.0,"publicationDate":"1997-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20090828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Pathologic examination of the sentinel lymph node.","authors":"J L Messina,&nbsp;L F Glass","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>One of the most important prognostic indicators in patients with malignant melanoma is lymph node status. While the five-year survival of stage I and II patients (without clinical adenopathy) is approximately 80 percent, this drops to 36-50 percent in patients with clinical or microscopic lymph node involvement. Other factors within lymph node specimens which affect disease-free and overall survival are the number of positive nodes (1 vs. 1-3 vs. 4 or greater) and the presence of extracapsular extension. Recently, the technique of sentinel lymphadenectomy has been developed to facilitate detection of metastatic disease in regional lymph nodes. Successful completion of this procedure requires a specialized but multidisciplinary approach, utilizing the surgeon, oncologist, nuclear radiologist, and pathologist. The pathologist's role is pivotal in this process, because identification of melanoma metastasis in the sentinel lymph node(s) is not only an important prognostic indicator but also dictates whether the patient will receive further surgery and adjuvant chemotherapy. Therefore, the goal of the pathologist in examining the sentinel lymph node is to maximize identification of nodal metastases of malignant melanoma. This is accomplished by following a standard protocol which fully utilizes all tissue submitted in concert with commonly available immunohistochemical techniques.</p>","PeriodicalId":76670,"journal":{"name":"The Journal of the Florida Medical Association","volume":"84 3","pages":"153-6"},"PeriodicalIF":0.0,"publicationDate":"1997-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20090822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
