Retrospective analysis of the efficacy of Gemcitabine for previously treated AIDS-Associated Kaposi’s Sarcoma in Western Kenya

Abstract

Objectives: Evaluation of outcomes in the use of single- agent gemcitabine for the treatment of AIDS-associated Kaposi’s sarcoma (KS) in a western Kenyan cancer treat- ment program. Methods: Retrospective chart review of all patients with KS treated with single agent gemcitabine fol- lowing failure of first-line Adriamycin, bleomycin, and vin- cristine (ABV). Baseline demographics were collected, and clinicians’ assessments of response were utilized to fill out objective criteria for both response as well as symptom ben- efit assessment. Results: Twenty-three patients with KS who had previously failed first-line therapy with ABV were evalu- ated. Following treatment, 22 of the 23 patients responded positively to treatment with stable disease or better. Of the 18 patients who had completed therapy, with a median fol- low-up of 5 months, 12 patients had no documented progression. Conclusions: Treatment options in the resource- constrained setting are limited, both by financial constraints as well as the need to avoid myelotoxicity, which is associ- ated with high morbidity in this treatment setting. This work shows that gemcitabine has promising activity in KS, with both objective responses and clinical benefit observed in this care setting. Gemcitabine as a single merits fur- ther investigation for AIDS-associated KS.
