- Abstract: Objective:To analyze clinical manifestations, pathological features and prognosis of patients with stage Ⅰ cutaneous melanoma.Methods:Clinical data were collected from 163 patients with stage Ⅰ cutaneous melanoma in Department of Dermatology, Xijing Hospital from January 2010 to January 2020, and clinical manifestations, pathological features, treatment methods and prognosis were retrospectively analyzed.Results:Among the 163 patients with stage Ⅰ cutaneous melanoma, 56 (34.36%) were males, and 107 (65.64%) were females, with a median age of 53 years at the clinic visit. Primary skin lesions were most frequently located on the extremities in 104 cases (63.80%) , of which 39 presented with lesions on the finger or toe nails and 65 with lesions on the other parts of the extremities; skin lesions were located at sun-exposed sites such as the head and face in 29 (17.79%) cases, and at non-sun-exposed sites such as the trunk and extremities except the hands and feet in 30 (18.40%) . Of the 163 patients, 56 (34.36%) were pathologically diagnosed with stage ⅠA cutaneous melanoma, and 107 (65.64%) with stage ⅠB cutaneous melanoma. According to a pathological staging system, 104 (63.80%) patients suffered from acral lentiginous melanoma, 23 (14.11%) superficial spreading melanoma, 15 (9.20%) nodular melanoma, 14 (8.59%) malignant lentigo-maligna melanoma, and 7 (4.29%) other rare or difficult-to-determine types. All the 163 patients received surgical treatment at least once, of whom 15 underwent finger or toe amputation, 94 extended resections, and 54 unextended resections; 35 received secondary surgeries, of whom 33 underwent extended resections and 2 finger amputation. Seven patients developed postoperative lymph node and/or distant organ metastases, 2 of whom died after distant organ metastases. The 5-year survival rate of the 163 patients was 98.00%.Conclusion:Stage Ⅰ cutaneous melanoma commonly has favorable prognosis, and 7 patients developed postoperative lymph node and/or distant organ metastases in this study, suggesting that long-term follow-up of patients with acral melanoma and early intervention of those with metastatic melanoma should be strengthened.
