GRECCAR 8: Primary Tumor Resection in Rectal Cancer With Unresectable Metastasis

Phase 3
Completed
Conditions
Rectal Adenocarcinoma
Interventions
Procedure: Primary tumor resection + chemotherapy
Drug: Oxaliplatin/irinotecan + capecitabine, 5-FUI ± bevacizumab
Registration Number
NCT02314182
Lead Sponsor
Hospices Civils de Lyon
Brief Summary

A prospective, open, multicenter, randomized III trial with two arms:

* Arm A: Primary tumor resection , followed by chemotherapy

* Arm B: Chemotherapy alone. Compare overall 2-year survival rates in patients treated for resectable rectal adenocarcinoma with unresectable metastasis, treated either with the primary tumor resection with chemotherapy +/- target therapy, or with chemotherapy (+/- target therapy) alone.

Primary Outcome Measures
NameTimeMethod
Overall survivalup to 2 years

Overall survival, defined as the time interval between the date of randomization and the date of death, with a 24 months' follow-up, in both treatment arms.

Secondary Outcome Measures
NameTimeMethod
Progression free survivalup to 2 years

Progression free survival will be assessed every 3 months during follow-up and will be estimated at 24 months.

Quality of lifeUp to 2 years

Quality of life will be assessed at the time of randomization and then every 3 months in both treatment arms. The EORTC QLQ-C30, QLQ-CR29 questionnaires will be used.

Toxicity of chemotherapy (Common Toxicity Criteria for Adverse Events (NCI-CTC-AE V4.0)Up to 2 years

Chemotherapy toxicity will be graded according to the National Cancer Institute Common Toxicity Criteria for Adverse Events (NCI-CTC-AE V4.0) in both treatment arms

Response of the metastatic disease to systemic chemotherapy (RECIST 1.1 criteria)up to2 years

The response rate of the metastatic disease will be evaluated in both treatment arms by CT scan and analyzed using the RECIST 1.1 criteria

Time to disease progressionup to 2 years

Time to disease progression is defined as the lapse of time between the date of randomization and the first date of progression (clinical or imaging) of the metastatic disease in both treatment arms, or of the primary rectal tumor in the chemotherapy arm (Arm B)

Post-operative morbiditywithin 30 days after surgical intervention

The evaluation of post-operative morbidity and mortality will be assessed in the primary tumor resection arm (Arm A) and in the chemotherapy arm (Arm B) for patients who require emergency surgery. The post-operative complications will be evaluated according to the Clavien-Dindo Classification of Surgical Complication and graded 0 to V.
