July 9, 2019 updated by: Universitaire Ziekenhuizen KU Leuven

A Randomized Phase II Study of Bevacizumab, Capecitabine and Radiation Therapy With or Without Oxaliplatin in the Preoperative Treatment of Locally Advanced Rectal Cancer

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pathologic Response at Surgery. Overview of Complete Pathologic Responses, Good and Little Tumour Regression Rates at Surgery.
Time Frame: 4 months
Dworak tumour regression grades (TRG) were used to assess pathologic response: TRG0=no regression. TRG1=dominant tumor mass with obvious fibrosis and/or vasculopathy; TRG2=dominant fibrotic changes with few tumour cells or groups; TRG3=very few (difficult to find microscopically) tumour cells in fibrotic tissue with or without mucus substance. TRG4=no intact viable tumour cells, only fibrotic mass or presence of mucin lakes without associated malignant cells (total tumour regression). Pathologic assessments of tumour response post chemoradiotherapy as provided by investigators (read by local pathologists on operative specimens) were reviewed centrally for all pts for whom surgical materials were available (centrally reviewed set). The diagnosis of independent central reviewers primed. Pathologic complete response rates (TRG4) are reported (%). Good (TRG3 and TRG4 together) and little (TRG 0,1 and 2) tumour regression rates are summarized. For these 2 last rows, % add to 100.
4 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Histopathologic R0 and Negative CRM Resection
Time Frame: 4 months
Histopathologic R0 resection rate was defined as margins histologically negative for tumour involvement after resection. The circumferential resection margin (CRM) is considered to be involved if microscopic tumour is present <1mm from or at the inked circumferential or radial resection margin. Data on quality of mesorectal excision were expected but not collected consistently.
4 months
Number of Participants With Pathologic Complete Response at Surgery. Number of Participants With Good or Little Pathological Tumour Regression at Surgery.
Time Frame: 4 months
Dworak tumour regression grades (TRG) were used to assess pathologic response: TRG0=no regression. TRG1=dominant tumor mass with obvious fibrosis and/or vasculopathy; TRG2=dominant fibrotic changes with few tumour cells or groups; TRG3=very few (difficult to find microscopically) tumour cells in fibrotic tissue with or without mucus substance. TRG4=no intact viable tumour cells, only fibrotic mass or presence of mucin lakes without associated malignant cells (total tumour regression). Pathologic assessments of tumour response post chemoradiotherapy as provided by investigators (read by local pathologists on operative specimens) were reviewed centrally for all pts for whom surgical materials were available (centrally reviewed set). The diagnosis of independent central reviewers primed. Pathologic complete response rates (TRG4) are reported (%). Good (TRG3 and TRG4 together) and little (TRG 0,1 and 2) tumour regression rates are summarized. For these 2 last rows, % add to 100.
4 months
Clinical Response Rate
Time Frame: 3 months

Baseline tumour measurements were performed within 4 weeks prior to treatment start (RECIST). The same methods of assessment (CT and/or MRI) were used for each measurable lesion at baseline and during follow-up.

  • Complete Response (CR) is disappearance of all clinical and radiological evidence of tumour (both target and non-target lesions).
  • Partial Response (PR) is at least a 30% decrease in the sum of LD of target lesions, taking as reference the baseline sum of tumour longest diameters (LD).
  • Stable Disease (SD) is steady state of disease. Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD.
  • Progressive Disease (PD) is at least a 20% increase in the sum of LD of measured lesions taking as references the smallest sum LD recorded since the treatment started. Appearance of new lesions constitutes PD. In exceptional circumstances, unequivocal progression of non-target lesions was considered evidence of PD.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
