Background:
Classic Kaposi's sarcoma is a rare tumor with an indolent behavior. Local therapy is not applicable in disseminated cutaneous disease. Patients with advanced disease are usually treated with systemic chemotherapy.
Objectives:
To assess the effectiveness and toxicity of single-agent vinblastine in the treatment of disseminated and recurrent Kaposi's sarcoma.
Methods:
Ten patients with wide cutaneous spread of classic Kaposi's sarcoma were treated with single-agent vinblastine, 6 mg/m2 intravenously once every 2 weeks. Vinblastine was continued for 2 months after achieving a maximal response.
Results:
The male:female ratio was 2.3:1, and median age 64 years (range 50-79 years). The median number of involved nodules in the skin was 34. The overall response rate was 90%, 5 with complete response (50%) and 4 with partial response (40%). Complete responders had a longer duration of response than partial responders: 41.2 vs. 14.8 months. The median survival of all patients was 33 months. Side effects were minimal and tolerable.
Conclusions:
Vinblastine is very effective in the treatment of extensive classic 'Kaposi's sarcoma, and results in a high response rate, long survival and disease-free survival with tolerable toxicity.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
