Renato Santos de Oliveira Filho, Daniel Arcuschin de Oliveira, Murilo Costa Souza, Mariane da Silva, Mireille Darc Cavalcanti Brandão

DOI: 10.1590/S1679-45082015AO3436

ABSTRACTObjective To analyze the distribution of larger diameter in the pathological report of cutaneous melanoma patients.Methods Data were obtained from patients seen from 1994 to 2015. Date, sex, age, maximum diameter, histological subtype, primary site, microscopic thickness, mitoses, ulceration, vertical growth phase, and regression were the variables studied. This study was approved by the National Ethics Committee – Brazil Platform. Patients were grouped into smaller diameter (≤6mm) and larger diameter (>6mm). The statistical analysis used the χ2test (p6mm). Out of […]

ObjectiveTo compare the level of vitamin D3 in cutaneous melanoma patients, with or without disease activity, with reference values and with patients from a general hospital.MethodsThe serum levels of vitamin D3 were measured in cutaneous melanoma patients, aged 20 to 88 years, both genders, from January 2010 to December 2013. The samples from the general group were processed at Hospital Israelita Albert Einstein (control group).

Fernanda Braga Silva, Renato Santos de Oliveira Filho, Wagner Iared, Álvaro Nagib Atallah, Ivan Dunchee de Abranches Oliveira Santos, Lydia Masako Ferreira

DOI: 10.1590/s1679-45082010rw1424

ABSTRACTObjective:To assess data on survival, recurrence and histological factors in positive and negative sentinel lymph nodes in thin melanoma cases.Methods:A systematic review was conducted on observational studies in four databases (Cochrane Library, Medline, Embase and Lilacs). Positive and negative micrometastases in sentinel lymph node biopsy were compared regarding the clinical outcomes – death and recurrence – and six histological factors – vertical growth phase, Breslow thickness, Clark level, ulceration, regression and mitosis rate.Results:Positive sentinel lymph node is statistically associated with […]
