Pediatric Germ Cell Tumor

A Non-Therapeutic Study that aims to establish a cohort of GCT survivors to understand short term and long-term adverse effects of treatment and to conduct molecular analyses to improve risk stratification.

Germ cell tumor has generally good prognosis, but high risk germ cell tumor has still very poor prognosis. There remains the need of further improvement with other chemotherapy strategy. Especially more than 11 years old, mediastinal germ cell tumor, stage 3 or 4 extragonodal germ cell tumor or the remained tumor after the primary treatment are the group with the poorest prognosis. Paclitaxel is widely used chemotherapeutic agent in adults and the experience of the agent has also been accumulated in children. The paclitaxel, ifosfamide, cisplatin (TIP) regimen has been used 2nd-line treatment for germ cell tumor and there is some promising result of the role of TIP in first line germ cell tumor treatment. In high risk pediatric germ cell tumor patients, TIP regimen will be able to reduce lung toxicity from the bleomycin as the standard regimen and to improve the survival. In this trial, the efficacy and safety of TIP as the first line treatment for germ cell tumor will be elucidated.
