A retrospective study of Kaposi’s sarcoma in Hotan region of Xinjiang, China

Abstract

Kaposi sarcoma (KS) is the most common cancer in patients with human immunodeficiency virus/acquired immunodeficiency syndrome (AIDS). In 1994, Chang and Moore discovered Kaposi sarcoma associated herpesvirus for the first time in KS lesions in AIDS patients. KS is a low-grade mesenchymal neoplasm of blood and lymphatic vessels that primarily affects the skin, although the disease may become disseminated to the lymphatic system, lungs, airways, or abdominal viscera. In this research, clinical characteristics and treatment of patients of Kaposi sarcoma were retrospectively analyzed in Hotan District, Xinjiang China. We look into the clinical traits, prognosis, and therapy of Kaposi sarcoma. From May 2017 to August 2022, 32 patients were treated in the People’s Hospital of Hotan District, Xinjiang Uygur Autonomous Region, China. Twenty-two of these were classic Kaposi sarcomas (cKS), and 10 of these were Kaposi sarcomas linked to AIDS (AIDS-KS). The majority of KS patients were Uyghur. In terms of age at onset, AIDS-KS patients were younger than cKS patients. cKS and AIDS-KS are most frequently manifested in the feet and lower limbs. Ten patients with AIDS-KS have treated with combination antiretroviral therapy (combination antiretroviral therapy) combination chemotherapy, 5 of 10 patients had a complete response, 2 patients achieved partial response, the overall effective rate was 70%, and CD4 + T cells were greater than before. For cKS and AIDS-KS, the median overall survival was 56 and 50.8 months, respectively (P > .05). As a result, antiviral combination chemotherapy can also improve the prognosis of AIDS-KS patients.
