Abt NB, et al. - Using Surveillance, Epidemiology, and End Results database from 1973 to 2012, the epidemiology and survival of primary conjunctival malignant neoplasms were investigated. Among 1661 cases, squamous cell carcinoma (SCC; at 54.8%) and melanoma (at 38.8%) were identified to be the most common neoplasms. Only age was identified to be the predictor of survival for SCC. Age, male sex, T4 tumors and N1 status are all survival predictors for melanoma. Researchers noted worse median survival time for blacks (52 months) compared to whites (118 months) and Asians/Native Americans/Pacific Islanders (145 months). No significant differences were evident between SCC and melanoma with respect to overall survival.
