Non-AIDS-related Kaposi's sarcoma: A single-institution experience

Area of Science:

• Oncology
• Dermatology
• Virology

Background:

• Kaposi's sarcoma (KS) is a complex malignancy.
• Non-AIDS-related KS presents distinct clinical characteristics.
• Understanding prognostic factors is crucial for patient management.

Purpose of the Study:

• To assess treatment outcomes for non-AIDS-related Kaposi's sarcoma.
• To identify prognostic indicators influencing patient survival.

Main Methods:

• Retrospective analysis of 32 patients with non-AIDS-related KS.
• Systemic chemotherapy regimens included vinca alkaloids, taxanes, and pegylated liposomal doxorubicin.
• Multivariable analysis identified prognostic factors, including lesion type.

Main Results:

• Overall response rate to chemotherapy was 43.9% (complete or partial).
• Median progression-free survival (PFS) was 11.7 months; median overall survival was 28.5 months.
• Nodular lesions were significantly associated with shorter PFS (HR: 3.09, P=0.0133).

Conclusions:

• Non-AIDS-related KS is primarily cutaneous and responds well to systemic therapy.
• Nodular lesion presentation is a negative prognostic factor for PFS in patients receiving chemotherapy.
