    Abstract: e21008 Background: Mucosal melanomas (MM) have a significantly worse survival outcome than cutaneous melanoma. The current staging rules for cutaneous melanoma do not apply to mucosal melanoma. Our previous studies have demonstrated mucosal melanomas arising from different anatomic sites can be staged and treated as a single disease entity. We are recommending a new evidence-based staging system for mucosal melanoma. Methods: The mucosal melanoma staging recommendations were made on the basis of a multivariate analysis of 543 patients with stages I, II, and III melanoma and 547 patients with stage IV melanoma to clarify TNM classifications and stage grouping criteria. Results: New staging definitions include the following: (1) in patients with localized melanoma, the depth of tumor invasion of the primary melanomas is the most dominant prognostic factor: T1 for tumor invading mucosa or submucosa; T2 for tumor invading the muscularis propria; T3 for tumor invading adventitia; T4 for tumor invading adjacent structures; (2) The dominant prognostic factor for regional nodal metastases is the number of metastatic nodes: N1 for 1 regional metastatic node; N2 for 2 or more regional metastatic nodes; (3) On the basis of a multivariate analysis of patients with distant metastases, the dominant component in defining the M category is the site of distant metastases (M1:lung only vs. M2:liver only vs. M3:brain only vs. M4:all other visceral metastatic sites). An elevated serum lactate dehydrogenase level would be designated in parenthesis. The staging grouping of mucosal melanoma can be defined as follow: (1) stage I: T1N0M0; (2) Stage II:T2-4N0M0; (3) Stage IIIA: T1-4N1M0, Stage IIIB: T1-4N2M0; (4) Stage IV: anyTanyNM1-4. Conclusions: Using an evidence-based approach, the proposed staging system of mucosal melanoma is the first to be established that reflects our improved understanding of this disease.

    Multivariate analysis of prognostic factors among 706 mucosal melanoma patients.
    American Society of Clinical Oncology (ASCO) ; 2017

    Abstract: 9569 Background: Mucosal melanoma is rare and associated with extremely poor prognosis. Little is known about its outcome and prognostic analysis. In this study, we evaluated prognostic factors among mucosal melanomas. Methods: The survival rates, Relapse Free Survival (RFS), Overall Survival (OS) and prognostic factors were compared for 706 mucosal melanomas at different anatomical sites. Results: Mucosal melanoma from nasal pharyngeal and oral (268 pts), upper and lower gastrointestinal (GI) (221 pts), gynecological and urological (196 pts) had a similar survival with a 1-y survival rate (88%, 83%, 86%), 2-y survival rate (66%, 57%, 61%), 5-y survival rate (27%, 16%, 20%), respectively. Multivariate analysis revealed that Depth of Invasion (p 〈 0.001), Lymph node metastases (p 〈 0.001), Distant metastases (p 〈 0.001) were three independent prognostic factors for OS among 706 pts. Anatomical site (p = 0.031), Depth of Invasion (p 〈 0.001), Lymph node metastases (p 〈 0.001) were three independent prognostic factors for RFS among 543 pts. KPS status, Depth of Invasion, Lymph node metastases, Distant metastases were independent factors for OS among nasal pharyngeal and oral pts. Depth of Invasion, Lymph node metastases, CKIT Mutation were independent factors for RFS among nasal pharyngeal and oral pts. Gender, Lymph node metastases, Distant metastases were independent factors for OS among GI pts. Gender, Depth of Invasion, Lymph node metastases were independent factors for RFS among GI pts. Lymph node metastases, Distant metastases were independent factors for OS among Gynecological and Urological pts. Depth of Invasion, Lymph node metastases were independent factors for RFS among Gynecological and Urological pts. Conclusions: This is the first prognostic analysis for mucosal melanoma with the largest sample size for the first time. with few exceptions, It revealed that Depth of Invasion, Lymph node metastases, Distant metastases were independent prognostic factors for OS, Depth of Invasion and Lymph node metastases were independent prognostic factors for RFS. These results should be incorporated into the establishment of stage system and design of future clinical trials involving patients with mucosal melanoma.
