Abstract
BACKGROUND Sentinel lymph node (SLN) biopsy in cutaneous melanoma patients evaluates the regional draining basin for occult micrometastatic disease. Occasionally, nonidentification of SLN impairs the acquisition of this important prognostic factor. OBJECTIVES To investigate the outcomes of melanoma patients with negative lymphoscintigraphic findings and patients who underwent SLN biopsy from 2004 to 2015 ( n = 1200) were retrospectively reviewed for tumor characteristics and clinical outcomes. METHODS Patients with nonvisualized lymph nodes (NV group) who underwent only preoperative lymphoscintigraphy were separated and compared with a cohort drawn from all melanoma patients who completed the surgical procedure within the same period (V group). RESULTS A negative lymphoscintigraphic scan was observed in 38 cases (3.2% of all patients). The NV group showed a significantly older age (median 66.0 vs. 48.3 years; P < 0.0001). Head and neck melanomas were more frequent in the NV group compared to the control group (25.1 vs. 7.8%; P = 0.009). Tumor characteristics such as ulceration and Breslow thickness do not influence the lymphoscintigraphy result. No differences were found in overall survival (OS) and disease-free survival (DFS) between the groups. CONCLUSIONS The nonvisualization of regional lymph nodes by lymphoscintigraphy is more frequent in older patients with head and neck melanomas. From the clinical point of view, no specific recommendation emerged for patients' management because the nonvisualization of the SLN did not show a significant influence on DFS and OS rates. However, lack of knowledge of lymph node status suggests performing a tighter follow-up eventually by ultrasound evaluation of all potential lymph node drainage basins.

The failure of a sentinel node biopsy due to an absence of nodal uptake of nuclear isotope in consecutive melanomas in a single patient – a physiological aberration. JPRAS Open 2022; 32:161-165.

Abstract
Nodal metastasis is an independent prognostic factor in patients with melanoma. Sentinel lymph node biopsy (SNB) is a recommended component of the management of patients with AJCC stage T1b or above. The dermal scar is injected with a Technetium-99 m (99MTc) Nanocolloid, a radiotracer that drains into sentinel nodes to be identified on a preoperative SPECT/CT scan. Intraoperatively the sentinel nodes are located using a gamma probe and patent blue dye. A 79-year-old male was referred to the Plastics Outpatient Department for management of a biopsy proven pT4b melanoma on the right flank and a suspicious lesion on the right shoulder. He was scheduled for a SNB and wide local excision of the flank melanoma and excisional biopsy of the shoulder lesion. He received injections of 99MTc Nanocolloid around the flank biopsy scar, however, preoperative, and intraoperative attempts to locate a node using radiological and surgical techniques were unsuccessful. The biopsy of the shoulder lesion sent for histopathology revealed a pT1b melanoma. A subsequent second SNB on the shoulder melanoma was unsuccessful, as 99MTc Nanocolloid failed to drain into a sentinel node for a second time. The drainage function of lymphatic vessels declines with age however the complete failure of nodal uptake is exceptionally rare. Novel radiotracers such as 99MTc Tilmanocept have shown superior lymph node tracking in recent tracers.

Abstract
BACKGROUND A 31-gene genetic expression profile (31-GEP; Class 1 = low risk, Class 2 = high risk) developed to predict outcome in cutaneous melanoma (CM) has been validated by retrospective, industry-sponsored, or small series. METHODS Tumor features, sentinel node biopsy (SNB) results, and outcomes were extracted from a prospective database of 383 C M patients who underwent SNB and had a 31-GEP run on their primary tumor. Groups were compared by uni- and multi-variable analysis. Relapse-free and distant metastasis-free survival (RFS, DMFS) were estimated by Kaplan-Meier method. RESULTS Breslow thickness, T stage, and SNB positivity were significantly higher in Class 2 patients. Recurrence rates were higher for Class 2 vs Class 1 patients and highest in patients who were Class 2 and SNB positive. GEP class was predictive of RFS and DMFS and independently predicted relapse in AJCC "low risk" (stages IA-IIA) patients. CONCLUSIONS 31-GEP adds prognostic information in CM patents undergoing SNB.

Prognostic Role of Non-Identification of Sentinel Lymph Node in Cutaneous Melanoma Patients: An Observational Retrospective Study. Cancers (Basel) 2020; 12:cancers12113151.

Abstract
Simple Summary Sentinel lymph node status is the most important prognostic factor for patients with cutaneous melanoma, but occasionally it is not possible to identify the sentinel lymph node. Little is known in cutaneous melanoma literature about the phenomenon of non-identification of sentinel lymph node and its prognostic implications. In this study we observed that not identifying the sentinel lymph node involves a worse nodal disease-free survival, but not a worse melanoma-specific survival than a negative sentinel lymph node. Potentially, patients with non-identified SLN should receive a follow-up schedule like that of patients with positive SLN. Abstract Background: Sentinel lymph node (SLN) status is recognized as the most important prognostic factor for patients with cutaneous melanoma. However, sometimes it is not possible to identify SLN. The phenomenon of non-identification of SLN and its prognostic role have not been thoroughly evaluated in melanoma literature. The objective of this study was to identify which patient or tumor variables may be associated to non-identification of SLN and to evaluate the prognostic role of non-identification of SLN. Methods: Observational retrospective study of 834 cutaneous melanoma patients who underwent SLN biopsy at Instituto Valenciano de Oncología. Results: Forty-two patients (5%) presented non-identification of SLN. Patients with age at diagnosis of ≥ 64 years, obesity (BMI ≥ 30), and head and neck localization were at higher risk of non-identification of SLN. Non-identified SLN patients had worse nodal disease-free survival with respect to negative SLN patients, but not worse melanoma-specific survival. Conclusions: Our findings suggest a need to follow-up patients with non-identified SLN in the same way as patients with positive SLN.

Abstract
The aim of this comprehensive review is to describe and analyze the role of the sentinel node mapping in head and neck cancers. For this purpose, head and neck neoplasms have been categorized in cutaneous malignancies and neoplasms of the upper aerodigestive tract. A concise description of lymphatic drainage will be the "prelude" for each section, as well as the description of the injection techniques, when specific. Concisely, the attention has been focused on detection rate of the sentinel node by lymphoscintigraphy for each cancer, and for those patients in which the sentinel lymph node has been identified, true-positives rates, false-negative rates, and overall accuracy has been pointed out. Overall, in cutaneous neoplasms of the head and neck, the detection rate is higher than 90%, however the false-negative rate is still an issue, in particular in melanoma, inducing the need for newer developments. In fact, new tracers and techniques are already available, while prospective multicenter trials exploring the outcome impact are needed in the near future. For the upper aerodigestive tract and in particular oral cavity and oropharynx, sentinel lymph node identification by lymphoscintigraphy allows avoiding unnecessary neck dissection and/or node irradiation. Even in this case, the main limit remains the risk of false-negative rates. While, for patients affected by laryngeal and hypopharyngeal cancers the data seem very limited and, although the feasibility has been demonstrated, performances of this lymphoscintigraphy still need to be confirmed by multicenter studies.

Abstract
INTRODUCTION Patient age has been intermittently associated with demographics and outcomes in cutaneous melanoma. We looked at the association of age and patient demographics, tumor features, and melanoma-related outcomes in patients undergoing sentinel lymph node (SLN) biopsy for melanoma. METHODS We reviewed demographics (age, gender), tumor features (mean Breslow thickness, ulceration, SLN positivity rates), and outcomes (all-site relapse, progression to stage IV, death from melanoma, complications) from a university-based prospective database of 1633 patients. Patients were grouped by decade of age and the impact of age was examined by univariable and multivariable analyses. RESULTS Increasing age was directly associated with number of patients referred for SLN biopsy, male gender, head and neck (H&N) tumor location, mean Breslow thickness, tumor ulceration, and with all -site relapse, progression to stage IV, death from melanoma and complication rates. Increasing age was indirectly associated with SLN positivity rates. Comparing ages <30 with ages >60, these trends reached statistical significance for male gender, H&N location, SLN positivity, all-site relapse, progression to stage IV (development of metastases) and death from melanoma. CONCLUSIONS Referrals for SLN biopsy increase with increasing patient age, yet increasing age is associated with lower SLN positivity rates. This occurs despite the fact that older patients have thicker, more ulcerated tumors, and higher melanoma-related relapse and death rates.

Reduction of lymphocele rate in patients undergoing sentinel node biopsy for melanoma by intraoperative placement of plant-based hemostatic powder: Results of a prospective trial. Am J Surg 2019; 217:878-881.

Abstract
BACKGROUND Lymphocele is a complication of sentinel node biopsy (SNB) for melanoma. Plant-based hemostatic powder (PBHP) may have a lymphostatic benefit. We studied whether PBHP placed intraoperatively could reduce lymphocele rates. METHODS We performed an open label, prospective, IRB -approved, before- and-after, matched control trial of PBHP placed into the wound in patients undergoing SNB of groin or axillary nodes for melanoma staging. Patient/tumor features and lymphocele rates were compared by standard statistical tests. RESULTS 66 control and 66 treatment (49 axillary and 17 groin in each arm) SNBs were performed in 61 and 55 patients, respectively, for a total 132 SNBs in 116 patients. Patient and tumor features were similar between groups. Nineteen lymphoceles occurred (14.4%); lymphocele rates were 22.2% (14/66) in the control group and 7.6% (5/66) in the treatment group (p = 0.026). The reduction in lymphocele rates between arms was greater for axillary than for groin sites (87.5% vs. 33%); the axillary reduction was statistically significant (p = 0.030). CONCLUSIONS Intra-operative placement of PBHP reduced the rate of lymphoceles in patients undergoing SNB for melanoma.

Abstract
BACKGROUND Lymphoscintigraphy is often performed before sentinel lymph node biopsy, especially in areas likely to have multiple or aberrant drainage patterns. This study aims to determine the incidence and characteristics of melanoma patients with negative lymphoscintigraphic findings and to review the management options and surgical recommendations. METHODS This is a retrospective study of patients with primary cutaneous melanoma who underwent sentinel lymph node biopsy between 2005 and 2016. Patients with nonvisualized lymph nodes on preoperative lymphoscintigraphy were compared in a 1:4 ratio with a randomly selected unmatched cohort drawn from all melanoma patients who underwent preoperative lymphoscintigraphy within the period of the study. Demographic, clinical, and outcome data were compared between these groups. RESULTS A negative lymphoscintigraphic scan was seen in 2.3 percent of all cases (25 of 1073). In both univariate and multivariate analyses, predictive patient- and tumor-specific factors for negative lymphoscintigraphy included older age and head and neck location. Patients with a nonvisualized sentinel lymph node had significantly worse overall survival compared with patients who had a visualized sentinel lymph node, but there was no difference in melanoma-specific survival. In 16 of the 25 cases (64 percent), at least one sentinel lymph node was found intraoperatively despite the negative lymphoscintigraphic findings. CONCLUSIONS Older patients with head and neck melanomas are more likely to experience nodal nonvisualization on lymphoscintigraphy. In patients who have nodal nonvisualization, the surgeon should attempt sentinel lymph node biopsy at the time of excision of the primary lesion because a sentinel lymph node can still be found in a majority of cases, and it offers prognostic information.
