The accuracy of predicting lymph nodes metastases in malignant melanoma by clinical examination and microstaging

Abstract

Since 1971, a prospective treatment regimen for primary cutaneous malignant melanoma performed by a single clinician has revealed the following early observations: 1) A significantly higher number of females with level II disease; 2) No recurrences or metastases to date in 29 patients with level II lesions treated by appropriate surgery; 3) The apparent clinical predictability of lymph node metastases in the group microstaged at level III. 4) An inability to predict lymph node metastases (or their delayed development) in patients with level IV disease; 5) A correlation between lymph node metastases and the development of disseminated disease.
