Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Testicular tumors account for 1% of all cancers in males and germ cell tumors comprise 95% of all testicular cancers. Seminomas consist of around 50% of cases. However,adequate information is not there as 60- 80% residual disease is seen even after with the standard management of chemotherapy.

With the advent of functional imaging there was hope that it could aid in more accurately targeting these tumors to systematically evaluate the role of PET-CT imaging in identifying patients diagnosed with stage IIB-IIIC seminomatous germ cell tumor, with residual visible tumor post chemotherapy who would benefit with loco regional radiotherapy.

The therapeutic research in Seminomashas been relatively slow and such structured studies can allow analysis of large number of patients to report on acute and late effect of treatment outcomes using CTCAE and QOL (EORTC QLQ C-30) in these cancers. We hope that we will get help in identifying thrust areas for future research through this study.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Radiotherapy

Patients randomized to the test arm will undergo radiotherapy to the residual mass. Patients will be stratified by the size of the residual mass in shortest dimension being \<3 cm or \> 3 cm.A dose of 30-36 Gy in conventional fractionation of 1.8-2.0 Gy per fraction using 3-dimensional conformal technique. Radiotherapy will be delivered five days a week.

Group Type EXPERIMENTAL

Radiotherapy

Intervention Type RADIATION

A dose of 30-36 Gy in conventional fractionation of 1.8-2.0 Gy per fraction using 3-dimensional conformal technique. Radiotherapy will be delivered five days a week.

Observation

Patients randomized to the standard arm will be observed and the status of residual mass monitored with an FDG PETCT scan done at three to six monthly intervals.

Group Type NO_INTERVENTION

No interventions assigned to this group
