Brief Summary

This trial is a prospective single arm intervention study, conducting clinical research on marketed drugs. Adverse drug reactions are controllable and the risk is low, with an estimated total of 40 cases. The main objective is to evaluate the safety and efficacy of teniposide combined with cisplatin in the treatment of newly diagnosed central malignant germ cell tumors, and to conduct drug monitoring on subjects to explore potential biomarkers for predicting therapeutic efficacy. It is expected to ultimately achieve the goal of prolonging the overall survival of patients, while providing more guidance for the screening of the best treatment population and biological predictive markers.

Conditions

GCT; Germ Cell Tumor; Central Malignant Germ Cell Tumor

Keywords

Central malignant germ cell tumor; GCT; teniposide; Cisplatin

Outcome Measures

Primary Outcomes (1)

• Objective response rate(ORR)

  The proportion of patients who achieved complete response (CR) or partial response (PR) ( i.e. CR PR) from the first use of the investigational drug to the period of withdrawal from the trial, compared to the total number of evaluable cases.

  3 weeks.

Study Arms (1)

Teniposide plus cisplatin

EXPERIMENTAL

Our study set up only one experimental group without a control group, and all subjects received the same intervention, namely the combination of Teniposide injection and Cisplatin for the treatment of newly diagnosed central malignant germ cell tumor patients. The effectiveness was assessed by observing the results and comparing them with historical data.

Drug: Teniposide Injection

Interventions

Teniposide Injection DRUG

teniposide 300mg/m2 for 5 days, cisplatin 75mg/m2 for 5 days

Also known as: cisplatin

Teniposide plus cisplatin
