About

The purpose is to evaluate the effectiveness and safety of albumin-bound paclitaxel (nab-PTX), ifosfamide and cisplatin in the treatment of children patients with advanced, recurrent or refractory extracranial germ cell tumor.

Full description

Children patients with advanced, recurrent or refractory extracranial germ cell tumor were treated with albumin-bound paclitaxel (nab-PTX), ifosfamide and cisplatin . This is a multi-center and single arm phase II clinical study.

Enrollment: 43 estimated patients
