Participants with mRCC who are being treated with bevacizumab at the recommended dose of 10 milligram per kilogram (mg/kg) of body weight once every 2 weeks as an intravenous infusion, in combination with interferon alpha-2a at the recommended starting dose of 9 million international units (MIU) 3 times a week until disease progression will be observed. No diagnostic or therapeutic interventions will be given other than used in normal daily routine.

Bevacizumab will be administered at the recommended dose of 10 mg/kg of body weight once every 2 weeks as an intravenous infusion until disease progression.

Tumor response was assessed as one of the following: Complete response (CR): disappearance of all target lesions and all pathological lymph nodes below 10 millimeter (mm). Partial response (PR): At least a 30 percent (%) decrease in the sum of diameters of target lesions. Stable disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD). PD: At least a 20% increase in the sum of diameters of target lesions, and the sum must also demonstrate an absolute increase of at least 5 mm or persistence of non-target lesions.

Disease control was defined as having achieved CR, PR, and/or SD during the course of the observation. CR: disappearance of all target lesions and all pathological lymph nodes below 10 mm. PR: At least a 30% decrease in the sum of diameters of target lesions. SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. PD: At least a 20% increase in the sum of diameters of target lesions, and the sum must also demonstrate an absolute increase of at least 5 mm or persistence of non-target lesions.

PFS time is defined as time between start of therapy and progression or death. Kaplan-Meier estimate was used for evaluation. PD: At least a 20% increase in the sum of diameters of target lesions, and the sum must also demonstrate an absolute increase of at least 5 mm or persistence of non-target lesions.

OS time is defined as time between start of therapy and date of death. Kaplan-Meier estimate was used for evaluation.

Participants with metastatic renal cell cancer (mRCC) who were treated with bevacizumab at the recommended dose of 10 milligram per kilogram (mg/kg) of body weight once every 2 weeks as an intravenous infusion, in combination with interferon alpha-2a at the recommended starting dose of 9 million international units (MIU) 3 times a week until disease progression were observed.

Full analysis set (FAS) included all participants who received at least one dose of study medication and have at least one post dose efficacy assessment, following the intention-to-treat principle. 'Number of participants analyzed' indicate participants with non-missing tumor response data.
