Abstract
BACKGROUND Current guidelines suggest that wide local excision of thick melanomas be delayed until sentinel lymph node biopsies can be performed. OBJECTIVE To examine the literature and determine if there is a scientific basis for delaying wide local excision of thick melanomas. MATERIALS AND METHODS A narrative review of the literature was undertaken to examine all available studies on the subject. RESULTS There is no evidence that prior excision compromises sentinel lymph node identification. There are multiple unsubstantiated suggestions that large rotation flaps may lead to false negatives. CONCLUSION There is no basis for delaying wide local excision of thick melanomas until a sentinel lymph node biopsy can be performed.

Abstract
BACKGROUND Sentinel lymph node biopsy (SLNB) has not been studied for invasive melanomas treated with Mohs micrographic surgery using frozen-section MART-1 immunohistochemical stains (MMS-IHC). The primary objective of this study was to assess the accuracy and compliance with National Comprehensive Cancer Network (NCCN) guidelines for SLNB in a cohort of patients who had invasive melanoma treated with MMS-IHC. METHODS This retrospective cohort study included all patients who had primary, invasive, cutaneous melanomas treated with MMS-IHC at a single academic center between March 2006 and April 2018. The primary outcomes were the rates of documenting discussion and performing SLNB in patients who were eligible based on NCCN guidelines. Secondary outcomes were the rate of identifying the sentinel lymph node and the percentage of positive lymph nodes. RESULTS In total, 667 primary, invasive, cutaneous melanomas (American Joint Committee on Cancer T1a-T4b) were treated with MMS-IHC. The median patient age was 69 years (range, 25-101 years). Ninety-two percent of tumors were located on specialty sites (head and/or neck, hands and/or feet, pretibial leg). Discussion of SLNB was documented for 162 of 176 (92%) SLNB-eligible patients, including 127 of 127 (100%) who had melanomas with a Breslow depth >1 mm. SLNB was performed in 109 of 176 (62%) SLNB-eligible patients, including 102 of 158 melanomas (65%) that met NCCN criteria to discuss and offer SLNB and 7 of 18 melanomas (39%) that met criteria to discuss and consider SLNB. The sentinel lymph node was successfully identified in 98 of 109 patients (90%) and was positive in 6 of those 98 patients (6%). CONCLUSIONS Combining SLNB and MMS-IHC allows full pathologic staging and confirmation of clear microscopic margins before reconstruction of specialty site invasive melanomas. SLNB can be performed accurately and in compliance with consensus guidelines in patients with melanoma using MMS-IHC.

Abstract
The publication of recent randomized trials has prompted a significant shift in both our understanding and the management of patients with melanoma. Here, the current management of the regional lymph nodes in patients with melanoma is discussed. This review focuses on selection for sentinel lymph node biopsy, management of the positive sentinel node, management of the clinically positive node, and the controversy over the therapeutic value of early nodal intervention.

Abstract
Aims and background Sentinel node (SN) biopsy has been introduced to solve the controversy concerning the effectiveness of prophylactic lymphadenectomy in intermediate thickness melanoma. The aim of this study was to evaluate the rate of metastases, the technical details of the procedure, and the main reasons of failure. Methods 235 patients affected by intermediate thickness melanoma (tumor thickness >0.75 mm and <4 mm) without clinical signs of systemic spread (N0M0) were submitted to sentinel node biopsy between 1996 and 2000. Preoperative lymphoscintigraphy was routinely performed in the last 184 patients. Intraoperative mapping with gamma probe was combined with the use of vital dye for identification of sentinel nodes in the last 113 patients. Results The SN detection rate was 95.6%, with significant differences depending on the site of dissection and the use of a gamma probe. The overall rate of micrometastases was 14.7%, but relevant differences were recorded between different subgroups of patients (T2, 5.1%; T3a, 19.6%; T3b, 29%). Conclusions Sentinel node biopsy requires a multidisciplinary approach (surgery, pathology and nuclear medicine) for reliable results. The association of vital dye and intraoperative gamma probe for sentinel node harvesting has made the procedure more effective, less time-consuming and less invasive. Failures may be due not only to surgical mistakes, but also to improper nuclear medicine procedures or inaccurate histological evaluation of SNs. Methods for histological examination of the SN are still debated and not standardized but promising results have recently been obtained with molecular oncology techniques (RT-PCR).

Abstract
Sentinel lymph node biopsy (SLNB) is a critical component of melanoma management. Extensive prior surgery at the site of a primary melanoma is considered a relative contraindication for SLNB. While evidence suggests that SLNB may be performed accurately even in those patients who have undergone prior wide local excision, it is less clear whether patients who have undergone more extensive surgical procedures, particularly flap reconstructions, can benefit from this procedure. We report a case of a patient who had undergone surgical removal of a primary melanoma and subsequent reconstruction with a rotational flap in whom a SLNB was performed successfully, which revealed nodal metastasis, suggesting that SLNB may remain an appropriate option in carefully selected patients who have previously undergone extensive surgery at site of primary disease.

Abstract
The aim of this study was to determine whether excision biopsy and primary closure of primary cutaneous melanoma modifies lymphatic drainage and accuracy of sentinel node biopsy. Thirty patients with 31 cutaneous melanomas were prospectively enrolled to undergo lymphoscintigraphy (LS) before and after excision biopsy. Tc-human serum albumin nanocolloid was first injected intradermally around the primary tumor and subsequently, after excision biopsy, adjacent to the scar. Sentinel nodes were identified by preoperative LS and the gamma-probe. Patent Blue V dye was injected intraoperatively before sentinel node biopsy. Intraoperative sentinel node identification was 100%. In 23 of 31 cases, both LSs were concordant in terms of nodal basins visualized. Two patients had a basin downstaged and six patients had a basin upstaged by the second LS. Only 50% of LS hot nodes stained blue (42 of 84). In 24 of 31 cases, the sentinel node was negative for metastases. Seven patients underwent complete lymph node dissection because of sentinel node positivity. Only one patient had metastases also to a non-sentinel node. After a median follow-up of 30 months lymph node metastases have not been observed in the eight discordant cases. This study shows that sentinel node identification and biopsy after lymphatic mapping is accurate after excision biopsy of primary cutaneous melanoma. Excision biopsy may, however, modify lymphatic drainage and a narrow excision margin should be performed if melanoma is suspected.

Abstract
BACKGROUND Melanoma is a commonly occurring cancer in Canada, with an estimated age-standardized incidence of 10 to 13 per 100,000. An estimated 4,300 new cases were diagnosed, and there were 800 reported deaths in 2005. OBJECTIVE AND CONCLUSION The Canadian Expert Panel on Malignant Melanoma has developed best practices to improve the management of malignant melanoma. Sections include recommendations on primary diagnosis, dermatopathologic assessment, and reporting; use of preoperative lymphoscintigraphy and an intraoperative gamma probe to map and biopsy the sentinel lymph node; indications for surgical resection, sentinel node biopsy, and surgery for advance disease; use of interferon-alpha adjuvant therapy and treatment options for stage IV disease; and management of central nervous system metastases.

Abstract
BACKGROUND We analyzed the variability and accuracy of sentinel lymph node (SLN) identification by lymphoscintigraphy performed preoperatively and repeated on the day of operation in patients with melanoma or Merkel cell cancer. METHODS Twenty-five prospectively studied patients had lymphoscintigraphy prior to and on the day of operation. Discordance between lymphoscintograms was defined as change in location of SLN or failure to identify a SLN by one of the studies. RESULTS In 22 of 24 assessable cases (92%), SLNs were excised. Preoperative lymphoscintigraphy was correct in 19 of 22 (86%) cases. Day of operation lymphoscintigraphy was correct in 20 of 22 (91%) cases. SLN location was as classically described in 24 of 25 (96%) cases. Discordance between lymphoscintigraphy studies was 32% (8/25 patients). Half with discordant migration (8%) yielded metastases in basins not identified by day of operation lymphoscintigraphy but demonstrated by preoperative lymphoscintigraphy. CONCLUSIONS Head and neck lymphatic drainage patterns not only vary between patients but also can vary with time for a single patient.

Abstract
BACKGROUND Although the utility of the sentinel lymph node biopsy (SLNB) in the staging of melanoma is well established, its usefulness in high-risk nonmelanoma skin cancer (NMSC) is yet to be determined. OBJECTIVE The objective was to report our experience with patients who underwent SLNB for the staging of a high-risk NMSC. MATERIALS AND METHODS We identified 13 patients with a high-risk NMSC who underwent SLNB between 1998 and 2006 and conducted a retrospective review of their medical records and tumor pathology. Their status as regards tumor recurrence and survival was obtained when possible. RESULTS Of 13 patients, 9 had squamous cell carcinoma (SCC), 2 had sebaceous gland carcinoma, 1 had porocarcinoma, and 1 had atypical fibroxanthoma. All SLNB were negative for metastatic disease, but 1 appeared to be a false-negative finding. CONCLUSION Compared to melanoma, SCC of the skin are much less predictable as regards their tendency to metastasize to the regional lymph nodes. Although the SLNB appears to be a reliable staging procedure for NMSC (especially SCC), the yield may be too low to justify its routine use in this patient population. More data are needed to determine when a SLNB is justified in the management of NMSC.

Abstract
BACKGROUND Since the advent of sentinel lymph node (SLN) biopsy, patients with cutaneous melanoma have been referred to surgeons for consideration for SLN biopsy, sometimes even after the wide local excision (WLE) of the primary melanoma has been performed. This has raised the question of the reliability and validity of a lymphoscintigram performed for lymphatic mapping of the SLN after there has been anatomic rearrangement of the skin following the WLE of this primary melanoma. METHODS We conducted a prospective study of 20 consecutive patients with cutaneous melanomas with thickness less than 1.00 mm, who volunteered to undergo preoperative and postoperative lymphatic mapping to determine if there were any changes in the lymph nodes that were identified following the WLE of the primary melanoma. Each of the patients had a resection with a minimum of 1.0 cm margin, and closure of their wounds with either transposition flap or double advancement flaps. RESULTS Lymphatic mapping was clearly identified in all 20 patients. One patient declined to undergo postoperative lymphatic mapping. Postoperative lymphatic mapping performed in the remaining 19 patients 2-4 weeks following WLE was identical to the preoperative mapping in 13 patients (68%), showed additional lymph nodes in 4-5 patients (21-26%), and showed fewer lymph nodes in 1-2 patients (5-10%). CONCLUSIONS Lymphatic mapping performed after a WLE of a primary cutaneous melanoma should be as reliable in identifying the SLN as a preoperative lymphatic mapping in 90% of the patients.

Abstract
Critical to the clinical management of a patient with malignant melanoma is an understanding of its natural history. As with most malignant disorders, prognosis is highly dependent on the clinical stage (extent of tumor burden) at the time of diagnosis. The patient's clinical stage at diagnosis dictates selection of therapy. We review the state of the art in melanoma staging, prognosis, and therapy. Substantial progress has been made in this regard during the past 2 decades. This progress is primarily reflected in the development of sentinel lymph node biopsies as a means of reducing the morbidity associated with regional lymph node dissection, increased understanding of the role of neoangiogenesis in the natural history of melanoma and its potential as a treatment target, and emergence of innovative multimodal therapeutic strategies, resulting in significant objective response rates in a disease commonly believed to be drug resistant. Although much work remains to be done to improve the survival of patients with melanoma, clinically meaningful results seem within reach.

Abstract
Wound defects resulting from wide local excision for cutaneous melanoma, can require the use of skin graft for closure. Harvesting the skin graft can result in an additional morbidity. The increasing use of sentinel lymph node biopsy in cutaneous melanoma allows us the development of an alternative technique for obtaining donor skin. This method utilizes the skin overlying the sentinel lymph node as the skin graft donor site. Sixteen patients with cutaneous melanoma over than 1 mm of Breslow index, underwent wide local excision with sentinel lymph node biopsy and full thickness skin graft harvested from the node biopsy site. After a median follow-up of 18 months, there were no graft failure, one case of lymph swelling was relieved in the donor site. There were no melanoma recurrence and no metastasis. One case of in transit metastasis was treated by local excision and suture. In cases were primary closure is not feasible or cosmetically unfavourable, the use of the sentinel lymph node site as a skin graft donor, provides an alternative technique sparing the patient an additional skin graft donor site defect.

Abstract
BACKGROUND Sentinel lymph node (SLN) status is the most important prognostic factor with respect to the survival of patients with primary cutaneous melanoma. However, lymphatic mapping and SLN biopsies (LM/SLNBs) performed in patients who have had a wide local excision (WLE) may not accurately reflect the pathologic status of the draining lymph node basins. The purpose of this study was to assess the feasibility and accuracy of LM/SLNB in patients who have had a previous WLE. METHODS A single-institution database was examined to identify patients who had a WLE before LM/SLNB and patients who had a concomitant LM/SLNB. Primary clinicopathologic features (age, tumor thickness, and ulceration), SLN identification rate, SLN pathologic status, and the incidence and sites of recurrences were compared between patients with and without prior WLE. RESULTS Of the 1395 patients identified, 104 had WLE before LM/SLNB. The mean preoperative WLE radial margin was 1.4 cm (median, 1.0 cm). LM/SLNB was successful in 103 of 104 (99%) patients. Age, tumor thickness, incidence of ulceration, and incidence of SLN positivity in the group with prior WLE were similar to those of the cohort of patients who had concomitant LM/SLNB and WLE (n = 1291). In 97 (93%) of the 104 prior-WLE patients, the surgical defects were closed by either primary closure or skin graft; 7 patients (7%) had rotational flaps. The median follow-up of these 104 patients was 51 months. Among the prior-WLE group, 19 patients (18%) had a positive SLNB; of these 19 patients, 4 (21%) had recurrences (3 distant failures and 1 local and distant failure). There were no lymph node recurrences-in a mapped or unmapped basin-in these 104 patients with a negative or positive SLNB. CONCLUSIONS SLNs can be successfully identified and accurately reflect the status of the regional lymph node basin in carefully selected melanoma patients with a previous WLE. Prior WLE does not appear to adversely impact the ability to detect lymphatic metastases, although the utility of LM/SLNB in patients who have undergone extensive reconstruction of the primary excision site remains to be defined. Because more extensive surgery may be required to accomplish accurate lymph node staging in patients who have undergone prior WLE-including the possible removal of SLNs from additional lymph node basins and an additional surgical procedure-to minimize morbidity and cost, concomitant WLE and LM/SLNB is strongly preferred whenever possible.

Abstract
BACKGROUND The staging of patients with primary melanoma is dependent on adequate sampling of the tumor thickness. Initial biopsies with a positive deep margin suggest inadequate sampling, potentially limiting accurate staging and affecting treatment decisions. METHODS To determine the efficacy of shave biopsy to adequately sample the tumor, we retrospectively reviewed our pathology database for original pathology reports of primary melanomas accessioned between 01/01/04 and 6/30/05. The biopsies were evaluated by technique, the presence of tumor at the margins of the specimen, and specimen thickness. RESULTS We identified 240 cases of primary melanoma; 223/240 were analyzable. The specimens were divided by biopsy technique (excisional, n = 51; punch, n = 44; and shave, n = 128). Shave and punch specimens had a significantly higher percentage of positive margins than excisional specimens (50, 68, and 16%, respectively; P < 0.0001). Shave specimens had a significantly higher percentage of positive deep margins than punch or excisional specimens (22, 7, and 2%, respectively; P = 0.0009). For melanomas <or=1 mm, shave specimens had a significantly higher percentage of positive deep margins than punch or excisional specimens (17, 0, and 0%, respectively; P = 0.0014). There was a significant difference in specimen thickness (P = 0.0005), with shave specimens being the thinnest. CONCLUSIONS The presence of tumor at the lateral margin of punch biopsies is an expected result, since this method is often used to diagnose lesions with a large diameter. The presence of positive deep margins in 22% of shave biopsy specimens compromises the ability of this technique to properly stage patients.

Abstract
Ten years after the introduction of the sentinel lymph node biopsy technique in the management of malignant melanoma, it is time to take stock. The complex method has proved itself sufficiently sensitive, although a certain percentage of false-negative histological results have to be taken into account. Presently, it is still a point at issue whether sentinel lymph node biopsy should be regarded as the standard of care in high-risk patients. Three prospective multicentre trials have failed to demonstrate a survival benefit resulting from elective lymph node dissection. In contrast, a retrospective multicentre study has recently shown that patients with node metastases diagnosed by the sentinel procedure benefit from early excision of their nodal disease in terms of overall survival, as compared to patients with delayed dissection of palpable nodes. Studies worldwide have established the pathologic status of the sentinel lymph node biopsy as the most important prognostic factor for recurrence and survival after the excision of primary melanoma. As with any invasive staging procedure, sentinel lymph node biopsy should have demonstrated therapeutic consequences. Unfortunately, an unequivocally acknowledged adjuvant therapy is lacking. Moreover, the impact of complete lymph node dissection after positive sentinel biopsy on survival or local disease control has not yet been clarified.

Abstract
Cutaneous melanoma remains an ongoing public health threat, and the cornerstone of management continues to be early diagnosis and treatment. Unfortunately, primary melanomas may have atypical presentations, making early diagnosis difficult and causing significant treatment delays. In this report, an unusual case is presented in which a patient experienced the synchronous development of a melanoma in situ within a skin graft donor site and an invasive melanoma within the recipient skin graft site. This exceptional presentation of cutaneous melanoma is discussed to highlight key principles of skin grafting in relation to the management of malignant melanoma.

Abstract
Sentinel node navigation surgery (SNNS) has received considerable attention for its role in deciding whether to perform neck dissection in patients with early oral cancer. However, diagnostic accuracy and its intraoperative availability of results remain important concerns. First, we shortened the examination time required for genetic diagnosis. Second, we assessed the quality of the extracted mRNA. Third, 10 patients with early N0 oral cancer underwent SNNS, using our new technique for genetic diagnosis to determine whether neck dissection was required. The examination time of our one-step reverse-transcriptase polymerase chain reaction method using a minicolumn and LightCycler was successfully shortened to 2 h, permitting intraoperative genetic diagnosis. The extracted mRNA was of high quality. Six sentinel nodes in four patients were diagnosed to be metastatic on genetic diagnosis; these patients underwent neck dissection. The other six patients avoided unnecessary surgery. We conclude that intraoperative genetic diagnosis of micrometastasis holds promise of being a sensitive method that can be used to support SNNS.

Abstract
Although sentinel lymph-node biopsy is accepted as a reliable method of staging of melanoma, it is not without problems to the pathologist. It has been re-emphasised that aggregates of benign naevus cells are not uncommon. Usually these are easily identified by a combination of their benign cytology and location in the fibrous skeleton of lymph nodes. This case represents a combination of an unusual pseudo-malignant pattern in the primary lesion with unusual morphology of the sentinel lymph node. The latter prompted reassessment of the cutaneous lesion as a benign naevus. Confirmation of the diagnosis as cutaneous melanoma by a positive sentinel-node biopsy was averted only by a careful comparison of unusual features of the putative primary and the sentinel lymph node. This case illustrates the need for a rigorous protocol for pathological assessment of sentinel lymph nodes for melanomas to assure detection of all metastases but also to avoid misdiagnosis and over-treatment. It also supports "benign metastases" as the mechanism underlying at least some melanocytes in regional lymph nodes.

Abstract
Sentinel node biopsy is an evolving staging tool in the management of patients with squamous-cell carcinoma of the head and neck. This tool provides a more detailed understanding of the lymphatic pathways within the head and neck and the role of these pathways regarding tumor spreading. By targeting nodes that are most likely to harbor disease, a more detailed pathological evaluation of sentinel nodes is possible-thus improving staging by the identification of micrometastases. The rationale behind the use of sentinel node biopsy to stage the N0 neck are discussed within this paper.

Abstract
The introduction of sentinel lymph node biopsy (SLNB) has been an important development in the management of malignant melanoma. Lymph nodes have long been known to play a key role in melanoma metastasis. The importance of nodal staging accounted for the previous surgical practice of elective lymph node dissection (ELND) even with its controversial impact on final outcomes and associated morbidity. Although this morbidity has been reduced with the ability to identify the SLN, numerous questions have subsequently surfaced with respect to this procedure's utility and therapeutic efficacy. This chapter will focus on the indications for SLNB, as well as the current controversies surrounding this procedure.

Abstract
OBJECTIVES/HYPOTHESIS The goals of the research study were to develop an easily mastered, accurate, minimally invasive technique of sentinel node radiolocalization with biopsy (SNRLB) in the feline model; to compare it with blue-dye mapping techniques; and to test the applicability of sentinel node radiolocalization biopsy in three head and neck tumor types: N0 malignant melanoma, N0 Merkel cell carcinoma, and N0 squamous cell carcinoma. STUDY DESIGN Prospective consecutive series studies were performed in the feline model and in three head and neck tumor types: N0 malignant melanoma (43 patients), N0 Merkel cell carcinoma (8 patients), and N0 squamous cell carcinoma (20 patients). METHODS The technique of sentinel node radiolocalization with biopsy was analyzed in eight felines and compared with blue-dye mapping. Patterns of sentinel node gamma emissions were recorded. Localization success rates were determined for blue dye and sentinel node with radiolocalization biopsy. In the human studies, all patients had sentinel node radiolocalization biopsy performed in a similar manner. On the morning of surgery, each patient had sentinel node radiolocalization biopsy of the sentinel lymph node performed using an intradermal or peritumoral injection of technetium Tc 99m sulfur colloid. Sentinel nodes were localized on the skin surface using a handheld gamma detector. Gamma count measurements were obtained for the following: 1) the "hot" spot/node in vivo before incision, 2) the hot spot/node in vivo during dissection, 3) the hot spot/node ex vivo, 4) the lymphatic bed after hot spot/node removal, and 5) the background in the operating room. The first draining lymph node(s) was identified, and biopsy of the node was performed. The radioactive sentinel lymph node(s) was submitted separately for routine histopathological evaluation. Preoperative lymphoscintigrams were performed in patients with melanoma and patients with Merkel cell carcinoma. In patients with head and neck squamous cell carcinoma, the relationship between the sentinel node and the remaining lymphatic basin was studied and all patients received complete neck dissections. The accuracy of sentinel node radiolocalization with biopsy, the micrometastatic rate, the false-negative rate, and long-term recurrence rates were reported for each of the head and neck tumor types. In the melanoma study, the success of sentinel node localization was compared for sentinel node radiolocalization biopsy, blue-dye mapping, and lymphoscintigraphy. In the Merkel cell carcinoma study, localization rates were evaluated for sentinel node radiolocalization biopsy and lymphoscintigraphy. In the head and neck squamous cell carcinoma study, the localization rate of sentinel node radiolocalization biopsy and the predictive value of the sentinel node relative to the remaining lymphatic bed were determined. All results were analyzed statistically. RESULTS Across the different head and neck tumor types studied, sentinel node radiolocalization biopsy had a success rate approaching 95%. Sentinel node radiolocalization biopsy was more successful than blue-dye mapping or lymphoscintigraphy at identifying the sentinel node, although all three techniques were complementary. There was no instance of a sentinel node-negative patient developing regional lymphatic recurrence. In the head and neck squamous cell carcinoma study, there was no instance in which the sentinel node was negative and the remaining lymphadenectomy specimen was positive. CONCLUSION In head and neck tumors that spread via the lymphatics, it appears that sentinel node radiolocalization biopsy can be performed with a high success rate. This technique has a low false-negative rate and can be performed through a small incision. In head and neck squamous cell carcinoma, the histological appearance of the sentinel node does appear to reflect the regional nodal status of the patient.

Abstract
OBJECTIVE To determine the feasibility of sentinel lymph node mapping in local and in-transit recurrent melanoma. SUMMARY BACKGROUND DATA The accuracy of intraoperative lymphatic mapping and sentinel lymphadenectomy (LM/SL) for identification of occult lymph node metastases is well established in primary melanoma. We hypothesized that LM/SL could be useful to detect regional node metastases in patients with isolated local and in-transit recurrent melanoma (RM). METHODS Review of our prospective melanoma database of 1600 LM/SL patients identified 30 patients who underwent LM/SL for RM. Patients with tumor-positive sentinel nodes (SNs) were considered for completion lymph node dissection. RESULTS Of the 30 patients, 17 were men and 13 were women; their median age was 57 years (range, 29-86 years). Primary lesions were more often on the extremities (40%) than the head and neck (33%) or the trunk (8%). At least 1 SN was identified in each lymph node basin that drained an RM. Of the 14 (47%) patients with tumor-positive SNs, 11 (78%) underwent complete lymph node dissection; 4 had tumor-positive non-SNs. The median disease-free survival after LM/SL was 16 months (range, 1-108 months) when an SN was positive and 36 months (range, 6-132 months) when SNs were negative. At a median follow-up of 20 months (range, 2-48 months), there were no dissected basin recurrences after a tumor-negative SNs. CONCLUSIONS LM/SL can accurately identify SNs draining an RM, and the high rate of SN metastases and associated poor disease-free survival for patients with tumor-positive SN suggests that LM/SL should be routinely considered in the management of patients with isolated RM.

Abstract
Lymphatic mapping and sentinel lymphadenectomy was developed as a minimally invasive technique to provide regional lymph node staging information for patients at high risk for metastatic melanoma, but without clinically palpable disease. Only patients who demonstrate micrometastases undergo complete regional lymphadenectomy, sparing approximately 80% of patients the expense and morbidity of an elective lymph node dissection. This technique has been widely accepted as the preferred method to determine the pathologic status of the regional lymph nodes and the staging information gained is incorporated into the latest version of the American Joint Committee on Cancer staging system for cutaneous melanoma. Still, there is much controversy as to the use of this technique as a staging procedure and its overall therapeutic benefit in the treatment of patients with melanoma. Currently ongoing clinical trials will determine if lymphatic mapping and sentinel lymphadenectomy directly influences overall survival for patients with malignant melanoma. We review the latest technical aspects of this procedure and discuss the controversies surrounding its use.

Abstract
BACKGROUND Patients have traditionally been considered candidates for sentinel node biopsy (SNBx) only at the time of wide local excision (WLE). We hypothesized that patients with prior WLE may also be staged accurately with SNBx. METHODS Seventy-six patients, including 18 patients from the University of Virginia and 58 from a multicenter study of SNBx led by investigators at the University of Vermont, who had previous WLE for clinically localized melanoma underwent lymphoscintigraphy with SNBx. Median follow-up time was 38 months. RESULTS Intraoperative identification of at least 1 sentinel node was accomplished in 75 patients (98.6%). The mean number of sentinel nodes removed per patient was 2.0. Eleven patients (15%) had positive sentinel nodes. Among the 64 patients with negative SNBx, 3 (4%) developed nodal recurrences in a sentinel node-negative basin simultaneous with systemic metastasis, and 1 (1%) developed an isolated first recurrence in a lymph node. CONCLUSIONS This multicenter study more than doubles the published experience with SNBx after WLE and provides much-needed outcome data on recurrence after SNBx in these patients. These outcomes compare favorably with the reported literature for patients with SNBx at the time of WLE, suggesting that accurate staging of the regional lymph node bed is possible in patients after WLE.

Abstract
BACKGROUND AND OBJECTIVES The role of sentinel lymph node biopsy (SLNB) in patients with a previous wide local excision (WLE) was examined with case-control methodology. METHODS A total of 168 consecutive cases of SLNB were performed in patients with truncal and extremity melanoma with tumor thickness of > or = 1 mm between October 1997 and June 2000 and were followed prospectively. For comparison, 65 of the 103 SLNB patients referred to us after their WLE (cases) were matched by tumor thickness to 65 patients who had SLNB with concurrent WLE (controls). Radiocolloid (technetium-99m sulfur colloid) was used in all cases; in addition, vital blue dye (patent blue) was used in the control group. The two groups were followed for a median of 15.4 months. RESULTS SLNs were identified in all patients with an average of 2.1 (cases) and 2.0 (controls) SLNs excised per patient (P = 0.77). Twenty one (32.3%) of those having SLNB after previous WLE (cases) and 23 (35.4%) of those with concurrent WLE and SLNB (controls) were found to have metastatic disease in the SLN. The only false-negative in this group was detected in clinical follow-up in a patient whose truncal WLE was previously closed with a rotation flap (case). There was no significant difference in relapse-free survival (P = 0.209) and overall survival (P = 0.692) between groups. CONCLUSIONS SLNB is feasible in patients with previous WLE for extremity and truncal melanoma. Similar rates of sentinel positivity are found when compared with those in whom their WLE was done concurrently.

Abstract
The emphasis of the research on the surgical treatment of melanoma has been on the resection margins, the role of elective lymph node dissection in high risk patients and the value of adjuvant regional treatment with hyperthermic isolated lymph perfusion with melphalan. Parallel to this research, new diagnostic techniques, such as Positron Emission Tomography and the introduction of the sentinel lymph node biopsy with advanced laboratory methods such as immuno-histochemical markers, and reverse transcriptase polymerase chain reaction, have been developed to facilitate early detection of metastatic melanoma. The role of these new techniques on the staging and surgical treatment of melanoma is discussed in this paper.

Abstract
Melanoma is a significant health problem. Despite public education and free cancer screenings, the incidence and mortality of melanoma continues to rise; however, many currently diagnosed melanomas are thin lesions, suggesting that education and awareness is having an impact. In addition, there are still subsets of patients who need increased surveillance in order to increase their survival. Although large congenital nevi may be precursors of melanoma, small and medium congenital nevi have an insignificant risk for melanoma development. Large congenital nevi, which are axial in location, appear to be more likely to develop melanoma and are associated with melanocytosis and melanoma of the CNS, both of which portend a poor prognosis. Recently, the recommended margins of excision have become more conservative so that many of the surgical defects can be closed primarily. Lymphoscintigraphy and sentinel node biopsy have replaced elective node dissections, thus decreasing the morbidity associated with the surgical management of melanoma. Although controversy still exists as to whether or not sentinel lymph node biopsy alters a patient's prognosis, it has been shown to be a powerful prognostic indicator. Although most melanomas are managed by routine surgical excision, other modalities are sometimes employed. For example, cryosurgery or radiation therapy may be indicated in the frail, elderly individual with a large facial lentigo maligna. Mohs surgery is the treatment of choice for head and neck melanomas and those located in areas where maximum preservation of tissue is required and for desmoplastic and acral lentiginous melanomas. Much more work remains in the area of adjuvant therapy, chemotherapy, and immunotherapy. Dacarbazine remains the drug of choice in disseminated melanoma, but remissions are usually short lived. Interleukin and biochemotherapy has yielded good results but the percentage benefiting is small. Although high dose interferon increases disease-free and overall survival in some patients, it remains a controversial drug which is not easily tolerated. In the new staging system for melanoma, ulceration is second only to Breslow's thickness. In transit (satellite) lesions have also been included in this new system. The new system also recognizes that patients with only microscopic metastatic nodal disease fare better than patients with clinically enlarged metastatic nodes and that it is the number of nodes involved with metastases, not their size, that determines the patient's prognosis. Except for lesions <1mm thick, the Clark's level of invasion has been de-emphasized.

Abstract
Sentinel node biopsy (SNB) has emerged as an accurate means of identifying nodal micrometastasis in cutaneous melanoma. In order to assess our learning curve, we compared our first 30 cases with our subsequent 30 cases. A total of 60 patients underwent SNB for cutaneous melanoma, using preoperative lymphoscintigraphy together with the intraoperative use of a Neoprobe and Patent Blue V dye. At least one sentinel node was identified in 93% of patients (90% in our first 30 cases; 97% in our subsequent 30 cases). Sentinel nodes contained tumour in 21% of cases. Of the sentinel nodes that contained tumour in the first 30 cases, 87% were identified by Neoprobe examination and 60% using blue dye. In the second 30 cases, the tumour-containing sentinel nodes were identified in all cases by both the Neoprobe and the blue dye. The sentinel node appeared to be the only involved node in 71% of patients. In the first 30 patients, one patient with a negative sentinel node developed nodal recurrence. These data confirm the feasibility of the sentinel-node technique in cutaneous melanoma. However, there is a learning curve, and the technique should be performed only by limited numbers of people with suitable training.
