Abdominoperineal resection provides better local control but equivalent overall survival to local excision of anorectal malignant melanoma: a systematic review

TLDR
It is suggested that APR has no survival benefit; however, APR confers better local control than LE, given that local failures after LE could be managed by salvage surgery, minimizing morbidity and maximizing quality of life should be the focus in surgical treatment of ARMM.
Abstract
Objective:To determine whether the extent of surgery is associated with survival in anorectal malignant melanoma (ARMM).Background:ARMM is a rare and highly malignant neoplasm with unfavorable prognosis. The optimal surgical management, abdominoperineal resection (APR) or local excision (LE), has be

Extensive surgery and lymphadenectomy do not improve survival in primary melanoma of the anorectum: results from analysis of a large database (SEER)

TL;DR: Analysis of data obtained from a national representative database finds the prognostic value of positive loco‐regional lymph nodes and the impact of lymphadenectomy on overall survival are unclear.

Clinical Characteristics of Malignant Melanoma in Southwest China: A Single-Center Series of 82 Consecutive Cases and a Meta-Analysis of 958 Reported Cases.

TL;DR: The clinical characteristics of melanoma in Chinese were different from those in Caucasians, and ulcer, tumor margins, and lymph node metastasis were significantly associated with prognosis.

Abdominal perineal resection or wilde local excision in primary anorectal malignant melanoma. Case report and review.

TL;DR: The higher serum levels of LDH and YKL-40 are suggestive for Anorectal Melanoma diagnosis and the decrease of these findings may be associated with good prognosis.

Bias in meta-analysis detected by a simple, graphical test

TL;DR: Funnel plots, plots of the trials' effect estimates against sample size, are skewed and asymmetrical in the presence of publication bias and other biases Funnel plot asymmetry, measured by regression analysis, predicts discordance of results when meta-analyses are compared with single large trials.
