Temozolomide in Aggressive Pituitary Neuroendocrine Tumors: A Latin American Multicenter Retrospective Cohort (TMZ-LATAM)

Temozolomide is the main chemotherapy drug used for aggressive pituitary tumors and pituitary carcinomas that do not respond to standard treatments like surgery or radiation. Most of what is known about how well this treatment works comes from small studies in Europe and the United States, with very little data from Latin America. Building on a previous multicenter study conducted in Brazil, this study (TEMPLA) expands data collection to additional centers across Latin America to better understand how patients in this region respond to temozolomide, how long the treatment controls the tumor, and whether certain tumor characteristics (such as MGMT status) can help predict which patients are more likely to benefit.
