The therapeutic value of sentinel lymph node biopsy (SLNB) in thin melanoma remains controversial. The aim of this study is to determine the role of SLNB in the survival of thin melanomas (≤1 mm). A multicenter retrospective observational study was designed.

Background: There is little evidence that smoking is associated with metastasis in patients with cutaneous melanoma.

Objective: Using a propensity score matching analysis, we assessed whether smoking was associated with a higher rate of sentinel lymph node (SLN) metastasis and worse survival in these patients.

Methods: Retrospective cohort study at a referral hospital for melanoma.

Mitotic rate is no longer considered a staging criterion for thin melanoma in the 8th edition of the American Joint Committee on Cancer Staging Manual. The aim of this observational study was to identify prognostic factors for thin melanoma and predictors and prognostic significance of sentinel lymph node (SLN) involvement in a large multicenter cohort of patients with melanoma from nine tertiary care hospitals. A total of 4249 consecutive patients with thin melanoma diagnosed from January 1, 1998 to December 31, 2016 were included.

The clinical value of sentinel lymph node (SLN) biopsy in thick melanoma patients (Breslow >4 mm) has not been sufficiently studied. The aim of the study is to evaluate whether SLN biopsy increases survival in patients with thick cutaneous melanoma, and, as a secondary objective, to investigate correlations between survival and lymph node status. We included 1,211 consecutive patients with thick melanomas (>4 mm) registered in the participating hospitals' melanoma databases between 1997 and 2015.

Background: Time between primary melanoma excision and sentinel lymph node biopsy (SLNB) has not been sufficiently studied as an independent predictor of survival in cutaneous melanoma.

Objectives: We used propensity score matching to evaluate whether early SLNB (performed ≤40 days from excisional biopsy) is associated with higher mortality in patients with cutaneous melanoma.

Materials & Methods: A retrospective cohort study at a tertiary melanoma referral centre.

Background And Objectives: Locoregional lymph node ultrasound is not typically included in guidelines as part of the staging process prior to sentinel lymph node biopsy (SLNB). The objective of the present study was to make a clinical and economic analysis of lymph node ultrasound prior to SLNB.

Materials And Methods: We performed a retrospective study of 384 patients with clinical stage I-II primary melanoma who underwent locorregional lymph node ultrasound (with or without ultrasound-guided biopsy) prior to SLNB between 2004 and 2015.

Background: The role of sentinel lymph node biopsy and the benefit of immunotherapy with interferon in thick (>4 mm) melanomas remain uncertain.

Objectives: Our aim was to assess the value of both sentinel lymph node (SLN) biopsy and immunotherapy in the prognosis of thick melanomas.

Methods: A retrospective study based on a computerized patient database in which patients have been prospectively collected since 2005 was performed.

Introduction: In patients with primary cutaneous melanoma, there is generally a delay between excisional biopsy of the primary tumour and sentinel-node biopsy. The objective of this study is to analyse the prognostic implications of this delay.

Patients And Method: This was an observational, retrospective, cohort study in four tertiary referral hospitals.
