Abstract:
Objective:To study the clinical characteristics of mucosal melanoma in the head and neck, including the risk factors affecting distant metastasis, recurrence and survival rate, and to provide the basis for the individualized treatment of mucosal melanoma in the head and neck.
Methods:The clinical data of 117 cases of mucosal melanoma in the head and neck treated from January 2004 to June 2016 in Beijing Tongren Hospital were analyzed retrospectively, and the risk factors affecting the prognosis, distant metastasis and local recurrence were analyzed.Kaplan-Meier analysis was used for survival analysis, and Log-Rank test was used for comparison between groups.
Results:The follow-up time was 5-139 months, with a median of 32 months, and the median survival time was 34 months.The 3 and 5 year cumulative survival rates were 47.0% and 25.0%, respectively.Local recurrence occurred in 27 patients (23.1%), and distant metastasis in 37 cases (31.6%). After the operation, 50 patients received radiotherapy.Multiple factor Cox regression analysis showed that distant metastasis, AJCC staging, and two operations were risk factors affecting survival (P<0.05), and immunologic/targeted therapy was a protective factor affecting survival prognosis(P=0.008). Postoperative radiotherapy and distant metastasis were important factors affecting recurrence (P<0.05). AJCC staging, pigmentation, and postoperative recurrence were risk factors for distant metastasis (P<0.05).
Conclusion:The 3 and 5 year survival rates of primary mucosal melanoma in head and neck are low, and the incidence of local recurrence and distant metastasis are high. Surgery is the first choice and the integrity of the initial operation has an important impact on the prognosis of the patients. Postoperative adjuvant radiotherapy is recommended to improve the local control rate, and immunotherapy and targeted therapy should be applied in time to improve survival.
