Description

Summary

This partially randomized phase II/III trial studies how well cisplatin and combination chemotherapy works in treating children and young adults with hepatoblastoma or liver cancer after surgery. Drugs used in chemotherapy, such as cisplatin, doxorubicin, fluorouracil, vincristine sulfate, carboplatin, etoposide, irinotecan, sorafenib, gemcitabine and oxaliplatin, 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. Giving combination chemotherapy after surgery may kill more tumor cells.

Pediatric Hepatic Malignancy International Therapeutic Trial (PHITT)

Details

PRIMARY OBJECTIVES:

  1. To reduce therapy associated toxicity for patients with non-metastatic hepatoblastoma (HB) and hepatocellular carcinoma (HCC) without adversely affecting long term outcomes.

II. To determine the event-free survival (EFS) in patients with HB whose tumor is completely resected at diagnosis and either receive no adjuvant chemotherapy (completely resected well differentiated fetal histology HB) or 2 cycles of standard dose cisplatin monotherapy (completely resected non-well differentiated fetal histology HB ? 100 mg/m2/cycle given 3 weeks apart). (Group A) III. To demonstrate that 4 to 6 cycles of interval compressed lower dose cisplatin monotherapy (80 mg/m2/cycle; 320 480 mg/m2 total) is adequate for low risk HB. (Group B) IV. In patients who are resected after 2 cycles of cisplatin monotherapy, to compare EFS following a randomized comparison of 2 versus 4 post-operative cycles of cisplatin monotherapy. (Group B) V. In patients whose tumors are deemed unresectable after 2 cycles of cisplatin monotherapy, to determine the proportion of tumors rendered completely resectable by an additional 2 or 4 cycles of chemotherapy. (Group B) VI. To compare in a randomized fashion, EFS in patients with intermediate risk HB treated with 6 cycles of cisplatin/5-fluorouracil/vincristine/doxorubicin (C5VD) chemotherapy versus 6 cycles of interval compressed cisplatin monotherapy (100 mg/m2/dose). (Group C) VII. To determine the EFS in patients with HCC whose tumor is completely resected at diagnosis who receive no adjuvant chemotherapy (completely resected HCC arising in the context of underlying liver disease) or 4 cycles of cisplatin/doxorubicin (PLADO) (completely resected de novo HCC). (Group E) VIII. To improve the EFS of patients with high risk HB by treating them with interval compressed cisplatin and doxorubicin based induction regimen followed by response-adapted consolidation therapy. (Group D) IX. In patients whose metastatic disease resolves with the administration of Societe Internationale d?Oncologie Pediatrique (SIOPEL) 4 Induction therapy, to determine if the promising pilot results observed in SIOPEL 4 can be validated in a large international study. (Group D1) X. In patients whose metastatic disease does not resolve with the administration of SIOPEL 4 Induction therapy, to determine in a randomized comparison which post induction treatment (irinotecan and vincristine sulfate [vincristine] alternating with carboplatin and doxorubicin or carboplatin and etoposide alternating with carboplatin and doxorubicin) results in superior outcomes. (Group D Arm CE & Arm VI) XI. In patients with unresectable/metastatic HCC at diagnosis, to determine whether the addition of gemcitabine and oxaliplatin (GEMOX + sorafenib) to a cisplatin, doxorubicin and sorafenib backbone improves chemotherapy response, resectability and survival. (Group F)

SECONDARY OBJECTIVES:

  1. Molecular characterization of HB tumors to validate newly identified molecular and immunohistochemical biomarkers correlating with known clinical prognostic factors and outcome. (Group A-D) II. To determine whether the molecular profile of pediatric HCC overlaps with HB or adult-type HCC while correlating biologic features with treatment response and survival. (Group E and F) III. To define the prognostic relevance in HB of a ?small cell undifferentiated? tumor component and percentage of tumor necrosis in post chemotherapy specimens.

IV. To determine the concordance of Pretreatment Extent of Disease (PRETEXT) and Post-treatment Extent of disease (POSTTEXT) based surgical guidelines and the surgical intervention performed.

  1. To determine which system (Children's Oncology Group [COG] PRETEXT, SIOPEL PRETEXT, or a new hybrid definition of PRETEXT) of the annotation factors for V, P, E, F and R provides the best prognostic information for determining response to chemotherapy, guiding risk based therapy, predicting surgical resectability, and EFS.

VI. To determine the concordance between institutional and expert panel review assessment of PRETEXT and POSTTEXT stage in an international cooperative group setting.

VII. To assess clinical characteristics, basic chemotherapy and surgical treatment details, biological characteristics at baseline and recurrence (when available) and outcome of patients with refractory or relapsed hepatoblastoma after initial treatment.

VIII. To identify novel biomarkers of renal toxicity (urine NGAL, cystatin C and Kim1) from cisplatin therapy when given according to the regimens used on this study, and to correlate such biomarkers with pharmacogenomics, other associated toxicities, and outcomes.

TERTIARY OBJECTIVES:

  1. To determine if the Childhood Hepatic tumor International Consortium (CHIC) hepatoblastoma risk stratification analysis of very low risk (Group A), low risk (Group B), intermediate risk (Group C) and high risk (Group D) groups stratifies patients allowing appropriate utilization of varying intensity chemotherapy regimens and surgical resection strategies.

II. To define the prognostic relevance of a positive microscopic margin in Group A-D resected HB specimens.

III. To define the frequency of histologically detectable multifocal lesions in liver explants and resected specimens in which multifocal disease was detected at diagnosis and disappeared on cross sectional imaging following treatment with chemotherapy.

IV. To determine the prognostic impact on EFS and overall survival (OS) of biopsy technique in liver tumors unresectable at diagnosis.

  1. To determine the frequency of intraoperative complications from surgery for local control (conventional resection or liver transplantation) and its impact on EFS.

VI. To determine the 3-year EFS and OS of HB patients who undergo liver transplantation versus (vs) extreme resection in Group C and D patients.

VII. To determine the 3-year EFS and OS of Group D patients who undergo pulmonary metastatectomy.

VIII. To determine the 3-year EFS and OS of patients who undergo liver transplantation for HCC.

IX. To determine the frequency of relapse in non-metastatic HCC in children treated by liver transplantation versus conventional resection.

  1. To assess the pharmacogenomics (PG) related to cisplatin therapy in pediatric and adolescent liver tumor patients and correlate PG with Boston Grading Scale for ototoxicity.
