Abstract
PURPOSE Perform an evidence-based review to determine the utility of indocyanine green fluorescence (ICG) to detect sentinel lymph nodes (SLN) in patients with head and neck melanoma compared to blue dye or radiocolloid injection (RI). MATERIALS AND METHODS A systematic review of the literature was performed to identify patients with head and neck melanoma managed with ICG fluorescence. PubMed, Embase, and Cochrane Library databases were searched. Included studies were assessed for level of evidence. Patient demographics and data on SLN identification were determined. RESULTS Twenty-two studies encompassing 399 patients (75% male, 25% female, average age 57.1 years) met inclusion criteria. Publications comprised of two case reports, four retrospective case series, twelve cohort studies, and four clinical trials. Most common site of melanoma was scalp/temple/forehead (35%), cheek/midface (22%), and ear (17%) with an average Breslow thickness of 3.32 mm. SLN was identified in 80.7% (n = 201/249) of patients using ICG-RI, 85.2% (n = 75/88) using RI alone, and 63.4% (n = 52/82) using blue dye-RI. CONCLUSIONS ICG-99mTc-nanocolloid hybrid tracer may be a superior alternative to blue dye + adiocolloid and has theoretical advantages compared to RI alone. Additional prospective randomized controlled trials are needed to further compare these methods and obtain data on false negative rates, operating room time, and cost effectiveness to fully elucidate the utility of ICG-99mTc-nanocolloid over current methods used for SLN identification in this patient population.

Abstract
BACKGROUND Lymph node involvement is a major independent prognostic factor for survival in patients with malignant melanoma. Sentinel lymph node biopsy (SLNB) detection of microscopic nodal melanoma has been shown to improve both 5-year survival and 5-year disease-free survival. OBJECTIVE To determine the rate of metastatic melanoma in SLNB-negative patients at long-term follow-up. METHODS Study subjects include all 152 patients who had a negative SLNB and were followed at the Ottawa Regional Cancer Centre (ORCC) between 1999 and 2004. Patients with a follow-up period less than 6 months, more than 1 primary melanoma, and metastatic melanoma at diagnosis were excluded. Age at diagnosis, sex, Breslow thickness, ulceration, mitoses, regression, Clark level, anatomical location, development of metastatic melanoma, time to detection of metastatic disease, and time to death from melanoma were studied. RESULTS In this retrospective study at the ORCC, 40 of 140 (28.6%) patients with a single primary melanoma developed metastatic melanoma following negative SLNB at a mean follow-up of 63 months. CONCLUSION The rate of metastatic melanoma following negative SLNB at long-term follow-up at the ORCC is higher than the upper limit of rates reported in the literature (6%-24%). The reason for this is multifactorial, and the long follow-up period of 5 years allowed for detection of metastatic disease at a mean of 3.9 years. Long-term prognosis may be guarded in node-negative patients with a primary cutaneous melanoma, and surveillance by a multidisciplinary team is crucial.

Abstract
Complete surgical excision at an early stage remains the only curative treatment for cutaneous melanoma with few available adjuvant therapy options. Nevertheless, melanoma is a relatively immunogenic tumor type and particularly amenable to immunotherapeutic approaches. A dense network of cutaneous dendritic cells (DC) may account for the reported efficacy of vaccination through the skin and provide an attractive target for the immunotherapy of melanoma. Several phenotypically distinct DC subsets are discernable in the skin, among others, epidermal Langerhans cells and dermal DC. Upon appropriate activation both subsets can efficiently migrate to melanoma-draining lymph nodes (LN) to prime T cell-mediated responses. Unfortunately, from an early stage, melanoma development is characterized by strong immune suppression, facilitating unchecked tumor growth and spread. Particularly the primary tumor site and the first-line tumor-draining LN, the so-called sentinel LN, bear the brunt of this melanoma-induced immune suppression-and these are exactly the sites where anti-melanoma effector T cell responses should be primed by DC in order to prevent early metastasis. Through local immunopotentiation or through DC-targeted vaccination, the dermis may be utilized as a portal to activate DC and kick-start or boost effective T cell-mediated anti-melanoma immunity, even in the face of this immune suppression.

Abstract
The aim of this study was to develop and evaluate 111In- and 99mTc-labeled derivatives of albumin nanocolloid (NC) for dual-label lymphoscintigraphy to allow simultaneous comparison of lymphatic flow from different tissue planes draining a tumour bed for accurate identification of sentinel lymph nodes (SLN). Using the chelator, p-isothiocyanatobenzyl-1,4,7, 10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA), 111In-DOTA-NC and 99mTc-DOTA-NC were compared in vitro with respect to stability of labeling, colloidal status and particle size, then in vivo by measuring their clearance rates from a subcutaneous injection depot. 111In-DOTA-NC and 99mTc-DOTA-NC were indistinguishable on the basis of in vitro criteria. Their in vivo clearance rates, however, were disparate (0.0015 to 0.075 min(-1) for 111In and 0.0072 to 0.067 min(-1) for 99mTc), 111In being faster in three studies and markedly slower in three. This demonstrates that even when dual-labeled radiotracers behave identically in vitro, they will not necessarily do so in vivo. Further work is needed to develop dual-labeled NC.

Abstract
BACKGROUND Despite the lack of an established survival benefit of sentinel lymph node (SLN) biopsy, this technique has been increasingly applied in the staging of thin ( METHODS MEDLINE, EMBASE, and Cochrane databases were searched for rates of SLN positivity in patients with thin melanoma. The methodologic quality of included studies was assessed using the Methodological Index for Non-Randomized Studies criteria. Heterogeneity was assessed using the Cochran Q statistic, and publication bias was examined through funnel plot and the Begg and Mazumdar method. Overall SLN positivity in thin melanoma patients was estimated using the DerSimonial-Laird random effect method. RESULTS Thirty-four studies comprising 3651 patients met inclusion criteria. The pooled SLN positivity rate was 5.6%. Significant heterogeneity among studies was detected (P = .005). There was no statistical evidence of publication bias (P = .21). Eighteen studies reported select clinical and histopathologic data limited to SLN-positive patients (n = 113). Among the tumors from these patients, 6.1% were ulcerated, 31.5% demonstrated regression, and 47.5% were Clark level IV/V. Only 4 melanoma-related deaths were reported. CONCLUSIONS Relatively few patients with thin melanoma have a positive SLN. To the authors' knowledge, there are no clinical or histopathologic criteria that can reliably identify thin melanoma patients who might benefit from this intervention. Given the increasing diagnosis of thin melanoma, in addition to the cost and potential morbidity of this procedure, alternative strategies to identify patients at risk for lymph node disease are needed.

Abstract
SUMMARY BACKGROUND DATA The more intensive sentinel node (SN) pathologic workup, the higher the SN-positivity rate. This is characterized by an increased detection of cases with minimal tumor burden (SUB-micrometastasis <0.1 mm), which represents different biology. METHODS The slides of positive SN from 3 major centers within the European Organization of Research and Treatment of Cancer (EORTC) Melanoma Group were reviewed and classified according to the Rotterdam Classification of SN Tumor Burden (<0.1 mm; 0.1-1 mm; >1 mm) maximum diameter of the largest metastasis. The predictive value for additional nodal metastases in the completion lymph node dissection (CLND) and disease outcome as disease-free survival (DFS) and overall survival (OS) was calculated. RESULTS In 388 SN positive patients, with primary melanoma, median Breslow thickness was 4.00 mm; ulceration was present in 56%. Forty patients (10%) had metastases <0.1 mm. Additional nodal positivity was found in only 1 of 40 patients (3%). At a mean follow-up of 41 months, estimated OS at 5 years was 91% for metastasis <0.1 mm, 61% for 0.1 to 1.0 mm, and 51% for >1.0 mm (P < 0.001). SN tumor burden increased significantly with tumor thickness. When the cut-off value for SUB-micrometastases was taken at <0.2 mm (such as in breast cancer), the survival was 89%, and 10% had additional non-SN nodal positivity. CONCLUSION This large multicenter dataset establishes that patients with SUB-micrometastases <0.1 mm have the same prognosis as SN negative patients and can be spared a CLND. A <0.2 mm cut-off for SUB-micrometastases does not seem correct for melanoma, as 10% additional nodal positivity is found.

Abstract
PURPOSE Impaired immune effector functions in the melanoma sentinel lymph node (SLN) may allow for early metastatic events. Local administration of PF-3512676 (formerly known as CpG 7909) has shown immunostimulatory effects of both dendritic cell and T-cell subsets in the melanoma SLN. Here, we set out to ascertain whether these PF-3512676-induced immunostimulatory effects translate into higher frequencies of melanoma-specific CD8(+) T cells. EXPERIMENTAL DESIGN Twenty-four stage I to III melanoma patients were randomized to preoperative local administration of either PF-3512676 or saline. CD8(+) T cells from SLN and peripheral blood were tested for reactivity by IFN-gamma ELISPOT assay against several HLA-A1/A2/A3-restricted epitopes derived from various melanoma-associated antigens (MAA) in 21 of 24 enrolled patients. Frequencies of natural killer (NK) cells and frequencies and maturation state of dendritic cell subsets in the SLN were determined by flow cytometry. RESULTS Melanoma-specific CD8(+) T-cell response rates against >1 MAA epitope in the SLN were 0 of 11 for the saline group versus 5 of 10 for the PF-3512676-administered group (P = 0.012). Of these 5 responding patients, 4 also had a measurable response to >1 MAA epitope in the blood. Increased frequencies in the SLN of both MAA-specific CD8(+) T cells and NK cells correlated to CpG-induced plasmacytoid dendritic cell maturation. CONCLUSIONS These data show an increase in melanoma-specific CD8(+) T-cell frequencies as well as an increased effector NK cell rate after a single dose of PF-3512676 and thus support the utility of local PF-3512676 administration as adjuvant treatment in early-stage melanoma to try and halt metastatic spread.

Abstract
Sentinel lymph node (SLN) biopsy affords an accurate, minimally invasive means of staging and determining prognosis in patients with melanoma and for identifying those patients who may benefit from complete regional lymph node dissection. Careful and accurate histopathologic assessment of SLNs is critical to achieving optimal reliability of the technique. Micromorphometric parameters of melanoma deposits in SLNs have been shown to be predictive of regional non-SLN involvement and of clinical outcomes. Several non-histopathologic methods of SLN evaluation have been investigated, and while some of them show promise for the future, excision and histopathologic examination currently remains the gold standard for the evaluation of SLNs.

Abstract
BACKGROUND Sentinel lymph node (SLN) biopsy has become the most widely used procedure to determine the regional lymph node status of patients with cutaneous malignant melanoma, and its application has spread rapidly to other malignancies such as squamous cell carcinoma of the skin, breast cancer and gastric cancer. OBJECTIVE SLN detection was performed in skin cancer patients using a newly developed real-time fluorescence navigation system with indocyanine green (ICG). METHODS SLN biopsy was performed by this method in 10 skin cancer patients (seven with melanoma and three with squamous cell carcinoma). After ICG was injected intradermally around the tumours, the lymphatic drainage was detected and the SLNs were identified by real-time fluorescence imaging. RESULTS The SLNs and their associated subcutaneous lymphatics were successfully identified in all patients. Fluorescence from SLNs was detected by this system for at least 3 hours after the injection of ICG. CONCLUSION SLN biopsy using ICG fluorescence achieves a high identification rate and allows effective observation for several hours. This method may become a useful option for the detection of SLNs in patients with skin cancer.

Abstract
Background The sentinel lymph node (SLN) biopsy technique is a reliable means of determining the tumor-harboring status of regional lymph nodes in melanoma patients. When technetium 99 m-labeled antimony trisulfide colloid (99 mTc-Sb2S3) particles are used to perform preoperative lymphoscintigraphy for SLN identification, they are retained in the SLN but are absent or present in only tiny amounts in non-SLNs. The present study investigated the potential for a novel means of assessing the accuracy of surgical identification of SLNs. This involved the use of inductively coupled plasma–mass spectrometry (ICP-MS) to analyze antimony concentrations in fine-needle biopsy (FNB) samples from surgically procured lymph nodes. Methods A total of 47 FNB samples from surgically excised lymph nodes (32 SLNs and 15 non-SLNs) were collected. The SLNs were localized by preoperative lymphoscintigraphy that used 99 mTc-Sb2S3, blue dye, and gamma probe techniques. The concentrations of antimony were measured in the FNB samples by ICP-MS. Results The mean and median antimony concentrations (in parts per billion) were .898 and .451 in the SLNs, and .015 and .068 in the non-SLNs, the differences being highly statistically significant (P < .00005). Conclusions Our results show that ICP-MS analysis of antimony concentrations in FNB specimens from lymph nodes can accurately confirm the identity of SLNs. Used in conjunction with techniques such as proton magnetic resonance spectroscopy for the nonsurgical evaluation of SLNs, ICP-MS analysis of antimony concentrations in FNB samples could potentially serve as a minimally invasive alternative to surgery and histopathologic evaluation to objectively classify a given node as sentinel or nonsentinel and determine its tumor-harboring status.

Abstract
Abstract
Background
Sentinel node (SN) status is the most important prognostic factor for overall survival in stage I or II melanoma. Yet SN-positive tumours with submicroscopic involvement of the SN (clusters of cells smaller than 0·1 mm) have shown a distant recurrence rate of only 9 per cent at 5 years, as good as that in SN-negative patients. This study compared the outcome after completion lymph node dissection (CLND) in SN-positive tumours with elective total lymph node dissection (TLND) in patients with palpable nodes.
Methods
A total of 188 patients were identified; 124 had TLND and 64 had CLND. Median follow-up was 56 and 37 months respectively. There were no significant differences between the groups regarding tumour Breslow thickness, ulceration and site of the primary tumour. Survival rates were calculated from date of primary excision. All patients with primary melanomas on extremities or trunk were included.
Results
On univariable analysis, the site of the primary tumour (extremity versus trunk) (P < 0·001), Breslow thickness (P = 0·005) and ulceration (P < 0·001) were prognostic for overall survival. There was a non-significant 13 per cent difference in overall survival at 5 years between CLND and TLND (P = 0·115). Excluding 15 patients who had SN disease with submicrometastases reduced the difference to 6 per cent (P = 0·415).
Conclusion
This study showed no significant survival benefit for SN-positive CLND compared with TLND, especially when patients with nodes containing submicrometastases were excluded.

Abstract
BACKGROUND In fair-skinned Caucasian populations both the incidence and mortality rates of cutaneous melanoma have been increasing over the past decades. With adjuvant therapies still being under investigation, early detection is the only way to improve melanoma patient survival. The influence of incisional biopsies on melanoma patient survival has been discussed for many years. This study investigates both the influence of diagnostic biopsy type and the presence of residual tumor cells in the re-excision specimen on disease free and overall survival. METHODS After (partial) removal of a pigmented skin lesion 471 patients were diagnosed with stage I/II melanoma and underwent re-excision and a sentinel node biopsy. All patients were followed prospectively, mean follow up >5 years. Patients were divided according to their diagnostic biopsy type (wide excision biopsy, narrow excision biopsy, excision biopsy with positive margins and incisional biopsy) and the presence of residual tumor cells in their re-excision specimen. Survival analysis was done using Cox's proportional hazard model adjusted for eight important confounders of melanoma patient survival. RESULTS The diagnostic biopsy was wide in 279 patients, narrow in 109 patients, 52 patients underwent an excision biopsy with positive margins and 31 patients an incisional biopsy. In 41 patients residual tumor cells were present in the re-excision specimen. Both the diagnostic biopsy type and the presence of tumor cells in the re-excision specimen did not influence disease free and overall survival of melanoma patients. CONCLUSIONS Non-radical diagnostic biopsies do not negatively influence melanoma patient survival.

Abstract
BACKGROUND We analyzed the outcomes and factors associated with false-negative (FN) results of sentinel lymph node (SLN) biopsy findings in patients with cutaneous melanoma. SLN biopsy failure rate was defined as nodal recurrence in the biopsied regional basin without previous local or in-transit recurrence. METHODS Between April 1997 and December 2004, a total of 1207 patients with cutaneous melanoma with a median Breslow thickness of 2.4 mm underwent SLN biopsy by preoperative and intraoperative lymphoscintigraphy combined with dye injection. In 228 cases, we found positive SLNs; of these, 220 underwent completion lymph node dissection (CLND). Median follow-up was 3 years. RESULTS The SLN biopsy failure rate was 5.8% (57 of 979 SLN negative). Median time to occurrence of FN relapse after SLN biopsy was 16 months (range, 3-74 months). The FN SLN biopsy results correlated with primary tumor thickness >4 mm (P = .0012), primary tumor ulceration (P = .0002), primary tumor level of invasion Clark stage IV/V (P = .0005), and nodular melanoma histological type (P = .0375). Five-year overall survival, calculated from the date of primary tumor excision, in the FN group was 53.7%, which was not statistically significantly worse than the CLND group (56.8%; P = .9). The FN group was characterized by a higher ratio of two or more metastatic nodes and extracapsular involvement of lymph nodes after LND compared with the CLND group (P < .0001 and P < .0001, respectively). Additional detailed pathological review of FN SLN revealed metastatic disease in 14 patients, which decreased the SLN biopsy failure rate to 4.4% (43 of 979). CONCLUSIONS Survival of patients with FN results of SLN biopsy does not differ statistically significantly from that of patients undergoing CLND, although it is slightly lower. The SLN biopsy failure rate is approximately 5.0% in long-term follow-up and is associated mainly with the same factors that indicate a poor prognosis in primary melanoma.

Abstract
Cutaneous melanoma is the most aggressive type of skin cancer. Paradoxically, melanoma is also the most immunogenic tumour identified to date: tumour-reactive T cells are detectable both in the blood and in tumour-draining lymph nodes (TDLN) of melanoma patients and their frequency can be increased by specific vaccination. However, early melanoma development is accompanied by impaired immune effector functions in the initial TDLN, the sentinel lymph node (SLN). Most notably, a reduced frequency and activation state of dendritic cells (DC) interferes with the uptake and presentation of tumour-associated antigens (TAA) to specific anti-tumour cytotoxic T-lymphocytes (CTL) and T helper cells (Th). These impaired immune effector functions may contribute to the early metastatic events that are associated with this tumour type. Since complete surgical excision at an early stage remains the only curative treatment option (adjuvant therapy options are limited and show no survival benefits), immunopotentiation of the SLN to jump-start or boost tumour specific immunity in early stage melanoma may be a valuable adjuvant treatment option that can be generally applied with minimal discomfort to the patient. Early clinical studies indicate that local Granulocyte/Macrophage-Colony Stimulating Factor (GM-CSF) or Cytosine-phosphate-Guanine (CpG) administration leads to activation of different DC subsets and conditions the SLN microenvironment to be more conducive to the generation of T-cell-mediated anti-tumour immunity.

Abstract
PURPOSE Impaired immune functions in the sentinel lymph node (SLN) may facilitate early metastatic events during melanoma development. Local potentiation of tumor-specific T cell reactivity may be a valuable adjuvant treatment option. EXPERIMENTAL DESIGN We examined the effect of locally administered granulocyte/macrophage-colony stimulating factor (GM-CSF) on the frequency of tumor-specific CD8+ T cells in the SLN and blood of patients with stage I melanoma. Twelve patients were randomly assigned to preoperative local administration of either recombinant human GM-CSF or NaCl 0.9%. CD8+ T cells from SLN and peripheral blood were tested for reactivity in an IFNgamma ELISPOT assay against the full-length MART-1 antigen and a number of HLA-A1, HLA-A2, and HLA-A3-restricted epitopes derived from a range of melanoma-associated antigens. RESULTS Melanoma-specific CD8+ T cell response rates in the SLN were one of six for the control group and four of six for the GM-CSF-administered group. Only one patient had detectable tumor-specific CD8+ T cells in the blood, but at lower frequencies than in the SLN. All patients with detectable tumor-specific CD8+ T cells had a percentage of CD1a+ SLN-dendritic cells (DC) above the median (i.e., 0.33%). This association between above median CD1a+ SLN-DC frequencies and tumor antigen-specific CD8+ T cell reactivity was significant in a two-sided Fisher's exact test (P = 0.015). CONCLUSIONS Locally primed antitumor T cell responses in the SLN are detectable as early as stage I of melanoma development and may be enhanced by GM-CSF-induced increases in SLN-DC frequencies.

Abstract
Significant advances have been made in all aspects of care relating to colorectal cancer. Although surgery will likely remain the mainstay of definitive treatment for the majority of colorectal malignancies, a better understanding of tumor progression and biology will help guide the choice of surgical therapy to best achieve a curative resection. Additionally, advances in the use of neoadjuvant and adjuvant therapies should continue to increase disease-free and overall survival when combined with appropriate operative resection. Although TNM staging remains our strongest tool at this point for establishing prognosis and directing therapy, expansion of our knowledge of the molecular events underlying colorectal tumorigenesis undoubtedly will lead to the refinement of our current staging and prognostic systems.

Abstract
BACKGROUND A significant proportion of newly diagnosed melanomas are thin lesions (< or = 1.00 mm). Because tumor thickness correlates with the risk for nodal metastases, sentinel lymph node (SLN) biopsy in this subset is controversial. Incorporating other prognostic factors (Clark level and ulceration), we evaluated the 6th edition American Joint Committee on Cancer (AJCC) clinical stage as a simple and widely applicable guideline for offering SLN biopsy for thin melanoma. METHODS This study was a review of a prospective melanoma SLN database from 1993 to 2003 with emphasis on SLN positivity rates based on the 6th edition AJCC primary tumor thickness intervals and clinical stage. RESULTS Three hundred five patients underwent SLN biopsy, with an overall positivity rate of 17.7%. By the 6th edition AJCC, lesions < or = 1.00 mm had an SLN positivity rate of 6.6%. By 6th edition clinical stage, SLN positivity rates were 4.9% for stage IA and 10.4% for stage IB. By using stage IA as the criterion for not offering SLN biopsy, this procedure would have been avoided in 46% (39 of 85) of < or = 1.00-mm melanoma patients with a negative SLN. CONCLUSIONS Sixth edition AJCC clinical stage IB as a selection criterion for performing SLN biopsy in thin melanoma identifies most patients with a positive SLN while also avoiding a negative SLN biopsy in many patients. Until additional widely accepted and validated selection criteria are available, SLN biopsy for clinical stage IB, but not stage IA, thin melanomas is a reasonable approach.

Abstract
Methods to work-up sentinel nodes (SN) vary considerably between institutes. This single institution study evaluated the positive SN-identification rate of the EORTC Melanoma Group (MG) protocol and investigated the prognostic value of the SN status regarding disease-free survival (DFS) and overall survival (OS) and evaluated the locoregional control after the SN procedure. Multivariate and univariate analyses using Cox's proportional hazard regression model was employed to assess the prognostic value of covariates regarding DFS and OS. The positive SN-identification rate was 29% at a median Breslow thickness of 2.00 mm and the false-negative rate was 9.4%. Breslow thickness and ulceration of the primary correlated with SN status. SN status, ulceration and site of the primary tumour correlated with DFS. SN status and ulceration of the primary correlated with OS. The in-transit metastasis rate correlated with SN-positivity, Breslow thickness and ulceration. Projected 3-year OS was 95% in SN-negative and 74% in SN-positive patients. Transhilar bivalving of the SN with step sections from the central planes is simple and had a high SN-positive detection rate of about 30%. The SN status is the most important predictive value for DFS and OS. In-transit metastasis rates correlated with SN-positivity, Breslow thickness and ulceration of the primary.

Abstract
The prognostic significance of spontaneous regression of primary melanoma is a controversial issue. Studies on sentinel lymph node status and circulating tumour cells may represent a step towards a better understanding. The clinical details of 269 melanoma patients who underwent sentinel lymph node biopsy were analysed. Correlation was sought between the parameters of the primary tumour, particularly tumours showing a partial intermediate level of regression, and sentinel lymph node status. The presence of circulating tumour cells was studied by reverse transcription-polymerase chain reaction for tyrosinase messenger RNA preoperatively in 94 patients. Of the examined tumours, 27.8% showed histological features of a partial intermediate level of regression. Regressive tumours were localized predominantly on the trunk (P=0.006), were significantly thinner (P<0.0000) and were less frequently ulcerated (P=0.003) than tumours without regression. Moreover, the majority of regressive melanomas were of the superficial spreading type (P<0.0000) and their sentinel node status was more favourable (P=0.026). We demonstrated the presence of circulating tumour cells in five of 26 (19.2%) regressive and 19 of 68 (29.4%) non-regressive tumours. The difference was not significant (P=0.32). By multivariate analysis, however, the Breslow thickness and ulceration of the primary tumour were predictors of the sentinel lymph node status, in agreement with literature data. A partial intermediate level of regression of the primary tumour did not affect unfavourably the sentinel lymph node status in our study. We failed to demonstrate a significant relationship between the presence of circulating tumour cells and either primary tumour regression or the sentinel lymph node status.

Abstract
BACKGROUND Even though 60% to 80% of melanoma patients with a positive sentinel lymph node (SLN) have no positive additional lymph nodes (ALNs), all these patients are subjected to an ALN dissection (ALND) with its associated morbidity. The aim of this study was to predict the absence of ALN metastases in patients with a positive SLN by using features of the primary melanoma and SLN tumor load. METHODS Of 71 SLN-positive patients, 52 had metastasis limited to the SLN (group 1), and 19 had > or =1 positive ALN after ALND (group 2). The tumor load of the SLN was assessed by measuring the total surface area by computerized morphometry. Breslow thickness, ulceration and lymphatic invasion of the primary tumor, and total SLN metastatic area were tested as covariates predicting the absence of positive ALNs. RESULTS The mean SLN metastatic area was 1.18 mm(2) (group 1) and 3.39 mm(2) (group 2) (P = .003) and was the only significant and independent factor after multivariate analysis (P = .02). None of the patients with both a Breslow thickness <2.5 mm and an SLN metastatic area <.3 mm(2) had a positive ALN. CONCLUSIONS SLN metastatic area can be used to predict the absence of positive ALNs in melanoma patients. In this study, patients with a Breslow thickness <2.5 mm and an SLN tumor load <.3 mm(2 )seemed to have no positive ALN and had excellent survival. We hypothesize that this subgroup might not benefit from ALND. Prospective larger trials, using this model and randomizing between ALND and no ALND, should confirm this hypothesis.

Abstract
The initial tumor-draining lymph node, the sentinel lymph node, not only constitutes the first expected site of micrometastasis but also the first point of contact between tumor-associated antigens and the adaptive immune system. A tumor-induced decrease in the frequency and activation state of sentinel lymph node dendritic cells will impair the generation of effective antitumor T-cell responses and increase the likelihood of metastatic spread. Here, we demonstrate that intradermal administration of granulocyte macrophage-colony stimulating factor around the excision site of stage I primary melanoma tumors increases the number and activation state of dendritic cells in the paracortical areas of the sentinel lymph node and enhances their binding to T cells. We conclude that local treatment of melanoma patients with granulocyte macrophage-colony stimulating factor, before surgery, conditions the sentinel lymph node microenvironment to enhance mature dendritic cell recruitment and hypothesize that this may be more conducive to the generation of T-cell-mediated antitumor immunity.

Abstract
Malignant melanoma (MM) early lymph node (LN) metastasis usually appears first in the sentinel LN (SLN). Breslow thickness is the main factor considered in the selection of patients to be submitted to SLN biopsy. The present study aimed to describe other independent prognostic factors useful in SLN candidate selection. During one year, 94 MM patients (90 primary cutaneous MM with Breslow thickness > or = 0.76 mm, and four cutaneous relapses), were submitted to SLN biopsy in the Melanoma Unit at the Hospital Clinic, Barcelona, Spain. The prognostic factors studied were: Breslow thickness, Clark's level of invasion, mitotic rate, cellular type (small, epithelioid, fusocellular, sarcomatoid), vertical growth phase, regression > 50%, severe vascularization, infiltrate (lymphocytic, plasmocytic), ulceration, neurotropism, intravascular/intraneural invasion, protein p16 expression and recurrence. Nineteen SLN (20.2%) were positive and 75 (79.8%) negative. No positive SLN occurred in MM with Breslow thickness < or = 1.0 mm. Breslow thickness > or = 2 mm (P = 0.005), severe vascularization (P = 0.005), small cell (P = 0.000) and ulceration (P = 0.005) were significant prognostic factors by univariate analysis. Small cell (P = 0.008) and ulceration (P = 0.05) were also significant prognostic factors in a multivariate analysis. The probability of finding a positive SLN for small cell was 56.9% [95% confidence interval (CI), 26.8-82.6%]. The probability of positive SLN for ulceration was 35.5% (95% CI, 14.2-64.7%). For small cell and ulceration together the probability increased to 86.3% (95% CI, 54.3-97.1%). The results of this study corroborated ulceration as a prognostic factor for SLN candidate selection and for the first time we have described small cell melanoma morphology as a significant factor associated with positive SLN.

Abstract
BACKGROUND In patients with head and neck squamous cell carcinoma (HNSCC), the presence of lymph node metastases is the most important prognosticator. Sentinel node (SN) biopsy has been shown to be an accurate staging technique for patients with breast cancer and melanoma and might also be suited for patients with HNSCC. This study was undertaken to determine whether the SN concept holds true for HNSCC and could be exploited for SN biopsy. METHODS In 22 patients with T2 to T4 N0 oral or oropharyngeal squamous cell carcinoma (SCC) who were scheduled to undergo combined primary tumor excision and elective unilateral (n = 17) or bilateral (n = 5) neck dissection, SN identification was performed the day before surgery by use of lymphoscintigraphy after peritumoral injections of 99mTc-labeled colloidal albumin. After the neck dissection specimens were removed, all SNs, all other radioactive lymph nodes, and all nonradioactive lymph nodes were retrieved for histopathologic analysis, including serial sectioning at 250-microm intervals and immunohistochemical analysis (IHC). RESULTS Overall, in 21 (78%) of 27 neck sides, an SN was identified by scintigraphy. Of the six neck sides in which SNs were not identified by scintigraphy, four were from three patients who underwent bilateral neck dissection. In another patient treated by bilateral neck dissection, the SN identified by scintigraphy could not be found in the specimen. In the remaining 20 neck dissection specimens, 23 SNs and 30 additional radioactive lymph nodes could be found. At histologic examination of the 20 neck specimens in which the SN was found, at least one SN was tumor positive in eight cases. In one neck specimen, a metastasis was detected in a nonradioactive lymph node, whereas the SN was tumor free, also at serial sectioning and IHC. In the remaining 11 neck sides in which the SN was tumor negative, none of the other radioactive (n = 13) and none of the nonradioactive (n = 279) lymph nodes contained tumor at histopathologic analysis, including serial sectioning and IHC. The sensitivity of the SN procedure for predicting lymph node metastases, therefore, was 89% (eight of nine neck specimens) when an SN was identified by scintigraphy and found in the specimen. The overall accuracy of the SN procedure for predicting the presence or absence of lymph node metastases in the neck was 95% (19 of 20 neck specimens). CONCLUSIONS Our study seems to validate the SN hypothesis for oral and oropharyngeal cancer. The role of SN biopsy in the management of the N0 neck in such patients has yet to be established through prospective trials. SN identification (and thus biopsy) does not seem to be reliable in patients with tumors located in or close to the midline.

Abstract
For patients with cancer it is essential to reach a definite diagnosis, obtain accurate staging and provide appropriate initial treatment if a successful outcome is to be achieved. These fundamental first steps in multidisciplinary care require close cooperation between surgical oncologists and pathologists. The most important aspect of this cooperation is clear and free exchange of information between them. The surgeon should provide the pathologist not only with an adequate tissue sample for examination, but also with clinical details that will assist in establishing a diagnosis. The location and orientation of specimens, and areas of particular concern, should always be indicated. Operative digital photographs may assist this process. The pathologist, in return, should provide the surgeon with a report containing sufficient information to allow an evidence-based management plan to be made for the patient, and to permit an accurate indication of prognosis to be determined. Use of a disease-specific synoptic report format will ensure that potentially important information is not overlooked. When there is diagnostic uncertainty, the pathologist should make this clear, but provide a preferred diagnosis. Further opinions may be helpful. If doubt exists, medico-legal considerations should not encourage a pathologist to issue a report with a diagnosis of malignancy. The pathologist should refrain from making management recommendations, because there may be valid reasons for the surgeon not providing this management. By cooperating fully and communicating freely with each other, surgical oncologists and pathologists can ensure high standards of initial and subsequent care for cancer patients.

Abstract
The sentinel node biopsy procedure is a highly accurate method of staging patients with cutaneous melanoma and the tumor-harboring status of sentinel nodes is the most important prognostic factor. For the procedure to provide accurate prognostic information, however, it is essential that 'true' sentinel nodes are removed and examined thoroughly. A technique to confirm sentinel node identity may reduce the false-negative rate of the procedure. We have found that antimony (originating from the antimony sulfide colloid used for preoperative lymphoscintigraphy in our institution) can be measured in tissue sections of sentinel nodes using inductively coupled plasma mass spectrometry. The aims of this study were to determine whether antimony concentrations can be used to confirm that removed sentinel nodes are 'true' sentinel nodes and to differentiate sentinel nodes from nonsentinel nodes. In all, 24 patients who had both a tumor-positive sentinel node and a tumor-negative nonsentinel node removed from one regional node field during the same operation, were identified. Tissue sections (50 microm) thick were cut from archival paraffin blocks of each of the sentinel nodes and nonsentinel nodes. Antimony concentrations in the tissue sections were measured using inductively coupled plasma mass spectrometry. The median and mean concentrations of antimony in parts per billion were 0.526 and 1.198, respectively (range 0.020-7.596) in the sentinel nodes, and 0.043 and 0.123 (range 0-0.800) in the nonsentinel nodes (P = 0.004). In four of the 24 pairs, both the presumed sentinel nodes and the nonsentinel nodes had very low antimony levels (less than 0.18 parts per billion), suggesting that nodes designated as sentinel nodes may not have been 'true' sentinel nodes. It is concluded that determination of antimony concentrations within sentinel nodes using the highly sensitive method of inductively coupled plasma mass spectrometry can confirm the identity of sentinel nodes and validate the sentinel node technique.

Abstract
AIMS To evaluate in detail the extent to which step sectioning and immunohistochemical examination of sentinel lymph nodes (SLNs) in patients with melanoma reveal additional node positive patients, to arrive at a sensitive yet workable protocol for histopathological SLN examination. METHODS The study comprised 29 patients with one or more positive SLN after a successful SLN procedure for clinical stage I/II melanoma. SLNs were lamellated into pieces of approximately 0.5 cm in size. One initial haematoxylin and eosin (H&E) stained central cross section was made for each block. When negative, four step ribbons were cut at intervals of 250 microm. One section from each ribbon was stained with H&E, and one was used for immunohistochemistry (IHC). RESULTS When taking the cumulative total of detected metastases at level 5 as 100%, the percentage of SLN positive patients increased from 79%, 83%, 83%, 90% to 93% in the H&E sections through levels 1-5, and with IHC these values were 83%, 86%, 90%, 97%, and 100%, respectively. One of six patients in whom metastases were detected at levels 2-5 only had metastases in the subsequent additional lymph node dissection. CONCLUSIONS Multiple level sectioning of SLNs (five levels at 250 microm intervals) and the use of IHC detects additional metastases up to the last level in melanoma SLNs. Although more levels of sectioning might increase the yield even further, this protocol ensures a reasonable workload for the pathologist with an acceptable sensitivity when compared with the published literature.

Abstract
The object of this study was to examine whether MUC-1 can be detected in the axillary lymphatic drainage of patients who have undergone conservative surgery for breast cancer and to assess the correlations between the presence of MUC-1 and prognostic factors in breast cancer. Sixty-eight women with invasive ductal carcinoma of the breast underwent wide local excision and axillary lymph node dissection. Axillary drains were inserted in all these cases, and the presence of MUC-1 and beta-actin was evaluated by RT-PCR in the lymphatic fluid collected after the operation. Prognostic factors included tumour size and grade, vascular and lymphatic invasion, clearance margins of the resected specimens and status of the axillary lymph nodes. RT-PCR assays for MUC-1 in the axillary fluid were positive in 17 patients (25%). The presence of MUC-1 was associated with increased tumour size and showed a positive correlation with axillary lymph node metastases and incomplete resection of the tumour. RT-PCR can disclose cancer cells in the axillary fluid after conservative surgery for breast cancer. The presence of MUC-1 in the axillary drainage may be associated with poor prognostic features, and its detection may have implications for therapy as it suggests that re-excision should be considered.

Abstract
FUNDAMENTOS: A progressão linfática do melanoma maligno habitualmente se inicia pelo linfonodo sentinela (LNS), cuja análise histopatológica permite predizer o acometimento de toda a cadeia. OBJETIVO: O trabalho tem por objetivo descrever a utilização do 99mTc-Fitato na detecção do LNS em pacientes com melanoma maligno, revisando as indicações e informações fornecidas por sua biópsia. MÉTODO: A pesquisa de LNS foi realizada por meio da linfocintilografia com 99mTc-Fitato em 92 pacientes com melanoma (54,0±14,3 anos). Após 18-24 horas, 88 pacientes foram submetidos à localização intra-operatória com detector portátil, seguida da ressecção e análise histopatológica do LNS. RESULTADOS: A linfocintilografia permitiu a identificação do LNS em todos os estudos, havendo detecção intra-operatória em 98,8% dos casos. O LNS estava acometido em 23 pacientes (26%). O valor preditivo negativo foi de 100% e não se observaram reações adversas pelo uso do 99mTc-Fitato. CONCLUSÃO: A detecção do LNS pode ser realizada com diferentes radiofármacos, incluindo o 99mTc-Fitato, que apresenta vantagens de custo e disponibilidade no Brasil. A pesquisa de LNS resulta em maior acurácia e menor morbidade no estadiamento de pacientes com melanoma maligno

Abstract
We have recently found that antimony (originating from the technetium 99m antimony trisulfide colloid, used for preoperative lymphoscintigraphy) can be measured in tissue sections from archival paraffin blocks of sentinel nodes (SNs) by means of inductively coupled plasma mass spectrometry (ICP-MS) to confirm that removed nodes are true SNs. We performed a retrospective analysis of antimony concentrations in all our false-negative (FN) SNs to determine whether errors in lymphadenectomy (i.e., failure to remove true SNs) may be a cause of FN SN biopsies (SNBs). Among 27 patients with an FN SNB, metastases were found on histopathologic review of the original slides or additional sections in 7 of 23 patients for which they were available; however, antimony concentrations were low in 5 of 20 presumptive SNs. Our results suggest that an FN SNB can occur because of failure to remove the true SN as well as histopathologic misdiagnosis.

Abstract
BACKGROUND In the current study, the authors assessed the efficacy of elective radiotherapy in providing regional (lymph node) control in patients with cutaneous melanoma of the head and neck who were at high risk for lymph node involvement. Toxicity was also assessed. METHODS From 1983 to 1998, 157 patients with Stage I or II cutaneous melanoma of the head and neck received elective regional radiotherapy after wide local excision of the primary lesion. None of the patients had received sentinel lymph node biopsy or dissection of the lymph nodes. Their medical records were reviewed retrospectively and analyzed for outcome. RESULTS The median follow-up for the current review was 68 months (range, 7-185 months). The disease recurred locally in 9 patients, in the neck lymph nodes in 15 patients, and distantly in 57 patients. The actuarial regional control rate was 89% at both 5 years and 10 years. The actuarial disease-specific survival and distant metastasis-free survival rates were 68% and 63%, respectively, at 5 years and 58% and 49%, respectively, at 10 years. Breslow thickness was a significant determinant of disease-specific survival and distant metastasis-free survival rates. At 10 years, 6% of patients had developed a symptomatic treatment-related complication. There were no treatment-related deaths. CONCLUSIONS The results of the current study confirmed the efficacy and safety of elective regional radiotherapy for patients with cutaneous head and neck melanoma predicted to have a high rate of lymph node involvement. Elective irradiation was a viable alternative to elective lymph node dissection. It may also serve as an alternative to sentinel lymph node biopsy, particularly for patients for whom dissection and systemic therapy are not therapeutic options.

Abstract
OBJECTIVE The purpose of this study was to investigate the feasibility of sentinel node detection through laparoscopy in patients with early cervical cancer. Furthermore, the results of laparoscopic pelvic lymph node dissection were studied, validated by subsequent laparotomy. METHODS Twenty-five patients with early stage cervical cancer who planned to undergo a radical hysterectomy and pelvic lymph node dissection received an intracervical injection of technetium-99m colloidal albumin as well as blue dye. With a laparoscopic gamma probe and with visual detection of blue nodes, the sentinel nodes were identified and separately removed via laparoscopy. If frozen sections of the sentinel nodes were negative, a laparoscopic pelvic lymph node dissection, followed by radical hysterectomy via laparotomy, was performed. If the sentinel nodes showed malignant cells on frozen section, only a laparoscopic lymph node dissection was performed. RESULTS One or more sentinel nodes could be detected via laparoscopy in 25/25 patients (100%). A sentinel node was found bilaterally in 22/25 patients (88%). Histological positive nodes were detected in 10/25 patients (40%). One patient (11%) had two false negative sentinel nodes in the obturator fossa, whereas a positive lymph node was found in the parametrium removed together with the primary tumor. In seven patients (28%), the planned laparotomy and radical hysterectomy were abandoned because of a positive sentinel node. Bulky lymph nodes were removed through laparotomy in one patient, and in six patients only laparoscopic lymph node dissection and transposition of the ovaries were performed. These patients were treated with chemoradiation. In two patients, a micrometastasis in the sentinel node was demonstrated after surgery. Ninety-two percent of all lymph nodes was retrieved via laparoscopy, confirmed by laparotomy. Detection and removal of the sentinel nodes took 55 +/- 17 min. Together with the complete pelvic lymph node dissection, the procedure lasted 200 +/- 53 min. CONCLUSION Laparoscopic removal of sentinel nodes in cervical cancer is a feasible technique. If radical hysterectomy is aborted in the case of positive lymph nodes, sentinel node detection via laparoscopy, followed by laparoscopic lymph node dissection, prevents potentially harmful and unnecessary surgery.

Abstract
The histologic status of the sentinel lymph node is a highly significant prognostic factor for patients with clinically localized cutaneous melanoma. The patterns of initial treatment failure of patients with positive sentinel lymph node biopsy versus those with negative results have not been well described. The purpose of this study was to determine the relative prognostic importance of sentinel lymph node status and to compare patterns of initial treatment failure and prognosis of node-positive versus node-negative cutaneous melanoma patients staged by sentinel lymph node biopsy and selective lymphadenectomy. The authors reviewed the pertinent demographic and surgical data in a consecutive series of patients with cutaneous melanoma who underwent sentinel lymph node staging of nonpalpable regional nodes. Sentinel lymph node biopsy was performed using a combination of blue dye and radiolocalization. Patients with positive biopsy results underwent selective lymphadenectomy, whereas those with negative results were observed. Site(s) and date(s) of initial recurrence and death were determined, and disease-free and overall survival probabilities were compared between positive and negative groups using the log-rank test and multivariable Cox regression analysis. Between February of 1994 and August of 2000, 408 patients with melanoma underwent sentinel lymph node biopsy to stage 518 regional lymph node basins. Mean Breslow tumor thickness was 2.27 mm (range, 0.2 to 14.0 mm). Eighty-five patients (20.8 percent) had at least one histologically positive sentinel lymph node, and selective lymphadenectomy yielded additional positive lymph nodes in 18 of 84 patients (21.4 percent). Recurrences were noted in 70 patients (17 percent) at a median follow-up period of 31.4 months. Recurrences were more frequent in patients with positive biopsy results (36.5 percent) than in those with negative results (12.1 percent, p < 0.0001). Distant sites of initial recurrence were more likely in the positive group than in the negative group (71 percent versus 49 percent of recurrences, respectively; p = 0.06). The false-negative rate for sentinel lymph node staging was 4.5 percent and overall accuracy was 99 percent compared with clinical follow-up. Disease-free and overall survival correlated significantly with tumor thickness, ulceration, sentinel lymph node status, and the number of tumor-positive lymph nodes (two-sided p < 0.0001 for all comparisons). Multivariable analysis revealed that sentinel lymph node status (p = 0.003), tumor thickness (p = 0.016), ulceration (p = 0.006), and age (p = 0.003) were significant independent predictors of survival for the entire group. Tumor thickness and ulceration were significant predictors of recurrence and survival in sentinel node-negative patients but not in sentinel node-positive patients. Sentinel lymph node histology is possibly the most important negative predictor of early recurrence and survival in patients with American Joint Committee on Cancer stage I and II melanoma. The number of positive lymph nodes provides additional prognostic information. Although sentinel node-negative patients are a prognostically favorable group, various combinations of local and regional recurrences comprise the most common pattern of initial relapse after a negative sentinel lymph node biopsy result.

Abstract
BACKGROUND The aim of this study was to evaluate the results of sentinel node biopsy in cutaneous melanoma at our institute. METHODS A total of 250 patients with cutaneous melanoma were studied prospectively. Preoperative lymphoscintigraphy was performed after injection of (99m)Tc-nanocolloid intradermally around the primary tumor or biopsy site (.32 mL, 65.5 MBq [1.8 mCi]). The sentinel node was surgically identified with the aid of patent blue dye and a gamma ray detection probe. The median follow-up was 72 months. RESULTS Lymphoscintigraphic visualization was 100%, and surgical identification was 99.6%. In 60 patients (24%), 1 or more sentinel nodes were tumor positive at initial pathology evaluation. Late complications after sentinel node biopsy of the remaining 190 patients were seen in 35 patients (18%). The false-negative rate was 9%. In-transit metastases were seen in 7% of sentinel node-negative and 23% of sentinel node-positive patients. The estimated 5-year overall survival rates were 89% and 64%, respectively (P <.001). CONCLUSIONS This study confirms that the status of the sentinel node is a strong independent prognostic factor. The false-negative rate and the incidence of in-transit metastases in sentinel node-positive patients are high and have to be weighed against the possible survival benefit of early removal of nodal metastases.

Abstract
This review surveys the staging systems used for the classification of colorectal carcinomas, including the TNM system, and focuses on the assessment of the nodal stage of the disease. It reviews the quantitative requirements for a regional metastatic work up, and some qualitative features of lymph nodes that may help in the selection of positive and negative lymph nodes. Identification of the sentinel lymph nodes (those lymph nodes that have direct drainage from the primary tumour site) is one such qualitative feature that is claimed to allow the upstaging of colorectal carcinomas via an oriented, enhanced pathological work up. Current evidence in favour of a change in the requisite of assessing as may lymph nodes as is possible, and concentrating the efforts on only a selected number of lymph nodes, is weak.
