What was measured

Overall response rate is defined as number of patients with complete response (CR) or partial response (PR) divided by all patients. Responses are evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST) guideline. CR is defined as disappearance of all target and non-target lesions. PR is defined as disappearance of target lesions or at least a 30% decrease in the sum of the diameters of target lesions (taking as reference the baseline sum diameters), and persistence of one or more non-target lesion(s).

Analysis population: All randomized patients

Groups in this outcome

Chemotherapy Arm (Arm A)

ARM A: Patients receive one of the four chemotherapy regimens ARM IA: Patients receive chemotherapy comprising docetaxel intravenously (IV) over 1 hour and cisplatin IV over 1-2 hours on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. ARM IIA: Patients receive docetaxel IV over 1 hour and carboplatin IV over 30 minutes on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. ARM IIIA: Patients receive cisplatin IV over 1-2 hours on day 1 and fluorouracil IV continuously on days 1-4. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. ARM IVA: Patients receive carboplatin IV over 30 minutes on day 1 and fluorouracil IV continuously on days 1-4. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Chemotherapy+Bevacizumab (Arm B)

ARM B: Patients receive bevacizumab in addition to the chemotherapy regimen as in arm A ARM IB: Patients receive bevacizumab IV over 30-90 minutes on day 1 and docetaxel and cisplatin as in Arm IA. ARM IIB: Patients receive bevacizumab as in arm IB and docetaxel and carboplatin as in Arm IIA. Regimen 2: ARM IIIB: Patients receive bevacizumab as in Arm IB and cisplatin and fluorouracil as in Arm IIIA. Regimen 2 carbo: ARM IVB: Patients receive bevacizumab as in Arm IB and carboplatin and fluorouracil as in Arm IVA.
