Retrospective analysis of 91 kaposi's sarcoma cases: A single-center experience and review of the literature

Abstract

Background: Kaposi's sarcoma (KS) is a multifocal angiopro-liferative tumor involving primarily the skin. Objective: The aim of this study was to describe the clinical, demographic, histopathological characteristics, treatment modalities, and outcome of 91 KS patients, and compare them with other contemporary research. Methods: Medical records of 91 KS patients followed between January 2005 and September 2017 were evaluated retrospectively. Results: Most of our patients were male (male-to-female ratio was 4.05). The median age at diagnosis was 69 years (range, 6-93 years). The duration of the lesions varied between 3 and 25 years. The lower extremities were the most commonly involved area (51.6%). Of the 91 patients, classic type KS was seen in 75 patients. Radiotherapy was used successfully in approximately half of our patients. Recurrence was observed in approximately one third of the patients. All KS patients in this study except 1 were classic KS. Conclusion: The clinical and demographic characteristics of our patients were compatible with the previous literature suggesting that KS is a tumor that tends to be limited to the skin. Close follow-up of patients is important to monitor for recurrence. This is the largest report from Turkey to date.
