Twenty-six patients, treated surgically between 1961 and 1986 because of lymph node metastasis from melanoma with an unknown primary, were analysed. Six patients had a history of spontaneous regression of a skin lesion. Following node dissection, the overall actuarial disease-free survival rate was 49 per cent, after both 5 and 10 years. When considered as single factors, female (versus male), one lymph node involved (versus more than one node involved) and site of metastasis in the groin or axilla (versus the neck) were found to have significantly favourable effects on prognosis with 5-year survival rates of 82 per cent (25 per cent), 82 per cent (27 per cent) and 80 per cent (11 per cent) respectively. However, at multifactorial analysis only the site of cervical metastases maintained a significant influence on survival (P = 0.005). As survival in this series is comparable with, or even better than, that of adequately treated patients with lymph node metastasis from a known primary melanoma, a radical node dissection is essential also in these patients.

UI MeSH Term Description Entries
D008207 Lymphatic Metastasis Transfer of a neoplasm from its primary site to lymph nodes or to distant parts of the body by way of the lymphatic system. Lymph Node Metastasis,Lymph Node Metastases,Lymphatic Metastases,Metastasis, Lymph Node

D008545 Melanoma A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world.

D012044 Regression Analysis Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
