Abstract
AIM: To describe the patterns of disease and clinical outcomes of MSK-KS in people living with HIV in the era of (combination anti-retroviral therapy cART).
PATIENTS AND METHODS: We reviewed our prospectively collected dataset of patients with HIV with biopsy-proven KS; 17 out of 1,489 seropositive patients were identified with subsequent evidence of MSK involvement by KS. We collected data with regards to clinicopathological parameters and radiological patterns of disease.
RESULTS: Fourteen patients (82.4%) had AIDS Clinical Trials Group T1 stage disease at presentation including four (23.5%) with non-nodal visceral disease. At the time of MSK-KS diagnosis, more than 80% of 14 patients had excellent HIV control. The median interval between initial KS to MSK-KS diagnosis was 3.3 years. Five-year overall survival rate from initial KS diagnosis was 76%, and 60% from MSK-KS diagnosis. The majority of patients were asymptomatic and MSK-KS involvement was demonstrated during imaging prompted by progression of their mucocutaneous KS. The majority of lesions were lytic with cortical involvement on cross-sectional imaging, whereas a soft-tissue component was commonly associated with long-bone involvement.
CONCLUSION: MSK-KS continues to be a rare entity in the modern era of cART, however patients appear to experience significantly improved survival.
