Primary malignant melanoma of the cervix: A comprehensive analysis of case reports in the Chinese population

PURPOSE: Malignant melanoma is a tumor generated from the basal melanocytes of human epidermis. Primary malignant melanoma of the cervix (PMMC) is derived from cervical melanocytes. It is an uncommon disease, mostly occurring in perimenopausal women. PMMC has a bad prognosis and lacks a defined protocol or treatment standards. The aim of this study was to analyze the impact of different surgical procedures and different adjuvant treatment modalities on their prognosis and to find risk factors for their prognosis by integrating published case report data based on the Chinese population. METHODS AND RESULTS: This study included 165 patients with PMMC in the Chinese population. We used the Kaplan‐Meier method to build the survival curve, and the log‐rank test to examine the variations among the subgroups. Prognostic factors were examined utilizing the Cox proportional hazards regression model. We found that patients who underwent radical hysterectomy‐based surgery, those who underwent lymphadenectomy, and those who underwent other treatments in addition to surgery had significantly better survival rates. The overall analysis, showed that age, and FIGO Stage II, III, and IV, increased the risk of death. Moreover, radical hysterectomy (RH), total hysterectomy (TAH), lymphadenectomy, and adjuvant therapy were correlated with a decreased mortality risk. CONCLUSION: After summarizing the current data, we recommend radical hysterectomy, and lymphadenectomy treatment for patients with PMMC. For patients who had already undergone surgery, other treatment options had a positive effect on prognosis. For patients who had already undergone surgery, other treatment options had a positive effect on prognosis; therefore patient‐specific treatment options need to be further discussed.
