Dose Intensification Study in Refractory Germ Cell Tumors With Relapse and Bad Prognosis (TICE)

This is an interventional treatment trial for Germ Cell Tumors focused on measuring refractory, germ cell tumors, relapse, bad prognosis, Refractory germ cell tumors with relapse and bad prognosis Read More

Inclusion Criteria:

1. Germ cell tumors whatever histology (TGNS or séminoma : TGS ) whose origin is gonadic, extra-gonadic, retro-peritoneal or primitive mediastinal
2. Age >= 18 years old
3. Histologically confirmed germ cell tumor (TGS) or biomarkers rate allowing to diagnose germ cell tumor without histology (TGNS)

4. Relapse or progression with bad prognosis in 1st treatment line : One of these criteria valid point 4 :

   progression after incomplete clinical response (Stable disease) to a Cisplatin basis chemotherapy; biomarker progression 4 weeks following the last chemotherapy cycle administration; progression during the first treatment line without obtention of at least stable disease; primitive mediastinal origin in first relapse.

5. TGNS or TGS in relapse after 2 treatment lines

6. Disease progression ( previous points 4 or 5) documented by :

   tumors biomarkers increase (AFP and/or HCG) if no, a biopsy is needed to confirm presence of tumors active cells

7. ECOG Performance status 0-2

8. Biological Function :

   Neutrophils >= 1500/mm3, Platelets >= 150.000/mm3 ; normal creatinine (or clearance >= 50 ml/mn) ; SGOT, SGPT <= 2,5N (or 5N if hepatic metastases), Bilirubin < 1,5N

9. Cardiac Functions (FEV >= 50%), Respiratory Functions , neurological Functions compatibles with high dose chemotherapy administration
10. Absence of previous intensification
11. Patient Information and Informed consent signature
12. HIV and B and C hepatitis negative serologies
13. Negative pregnancy test for women with reproductive potential and adequate contraception before study entry
14. Patient affiliated to social security system

Exclusion Criteria:

1. Patients whose diagnosis of relapse was not confirmed by an anatomopathological examination or by an increase of tumors markers
2. Primitive encephalic germ cell tumors
3. Germ cell tumors in relapse with favorable factors of treatment response to conventional chemotherapy (RC sustainable after Cisplatin): prior cRC or incomplete clinical response but with normalization of markers and testicular origin
4. Growing Teratoma lesions
5. Patients with HIV infection, hepatitis B and C
6. Patients with symptomatic brain metastases despite appropriate corticosteroid treatment
7. Associated pathology may prevent the patient to receive treatment, creatinine clearance ≤ 50 mL / min (calculated by Cockcroft-Gault)
8. FEV <50%
