Active Surveillance, Bleomycin, Carboplatin, Etoposide, or Cisplatin in Treating Pediatric and Adult Patients With Germ Cell Tumors

• Status: Recruiting
• Trial end date: 2027-06-30
• Target enrollment: 0
• Participant gender: All

Summary

This phase III trial studies how well active surveillance, bleomycin, carboplatin, etoposide, or cisplatin work in treating pediatric and adult patients with germ cell tumors. Active surveillance may help doctors to monitor subjects with low risk germ cell tumors after their tumor is removed. Drugs used in chemotherapy, such as bleomycin, carboplatin, etoposide, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.

• Phase: Phase 3

• Low risk stage I immature teratoma (IT); site: ovarian; stage: Children's Oncology Group (COG) stage I, Federation of Gynecology and Obstetrics (FIGO) stage IA and IB; grade: 2 or 3; histology: pure immature teratoma (may contain microscopic foci of yolk sac tumor), mixed immature and mature teratoma, (no pathological evidence of MGCT); tumor markers: alpha-FP =< 1,000 ng/mL, beta-HCG institutional normal; all ages

• Standard risk 2 (SR2)

• Site: ovarian; stage: COG stage II and III, FIGO stage IC, II and III; histology:

must contain at least one of the following: yolk sac tumor, embryonal carcinoma, or choriocarcinoma; age (years) >= 11 and < 25

• Site: testicular; stage: COG stage II-IV, AJCC stage II, III, IGCCC good risk; histology: must contain at least one of the following: yolk sac tumor, embryonal carcinoma, or choriocarcinoma; tumor markers: must be IGCCC good risk; post op: alpha-FP < 1,000 ng/mL, beta-HCG < 5,000 IU/mL and lactate dehydrogenase (LDH) < 3.0 x normal; age (years) >= 11 and < 25

• Site: extragonadal; stage: COG stage II; histology: must contain at least one of the following: yolk sac tumor, embryonal carcinoma, or choriocarcinoma; age (years) >= 11 and < 25

• Notes:

• IGCCC criteria only apply to SR2 patients with a testicular primary tumor

• Use post-op tumor marker levels to determine IGCCC risk group

• Stage 1 seminoma patients are not eligible for the standard risk arms of the study

• For the low risk stage I non-seminoma MGCT and the standard risk arms, components of yolk sac tumor, embryonal carcinoma, or choriocarcinoma can be mixed with other forms of GCT, such as seminoma or mature or immature teratoma; if yolk sac tumor is the only malignant component present, then it must be deemed by the pathologist to be greater than a "microscopic component" of yolk sac tumor

• Patients must have a performance status corresponding to Eastern Cooperative Oncology Group (ECOG) scores of 0, 1, 2 or 3; use Karnofsky for patients > 16 years of age and Lansky for patients =< 16 years of age

• Organ function requirements apply ONLY to patients who will receive chemotherapy (SR1 and SR2 patients)

• Creatinine clearance or radioisotope glomerular filtration rate (GFR) >= 70 mL/min/1.73 m^2

• A serum creatinine based on age/gender as follows: (mg/dL)

• Eligibility criteria to participate in the pilot study of the AYA-Hears instrument (patient reported outcomes [PROs] of ototoxicity) Note: participants in group 1 will not receive AGCT1531 protocol-directed therapy; all other AYA-HEARS patients must be enrolled on the AGCT1531 SR2 arm in order to participate
