Brief summary

This clinical trial studies the feasibility of using hypo-fractionated radiotherapy for the treatment of cervical or endometrial cancer. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects.

Detailed description

PRIMARY OBJECTIVE: I. To establish the trial as feasible and to assess the impact upon acute gastrointestinal toxicity in the third week of pelvic radiotherapy following a hypo-fractionated schedule. SECODARY OBJECTIVES: I. To estimate impact upon acute urinary toxicity. II. To estimate impact upon patient reported gastrointestional toxicity. III. To assess acute quality of life following treatment. IV. To quantify acute financial toxicity following treatment. V. To assess satisfaction with decision-making following treatment. VI. To assess the overall survival throughout 3 years of post-treatment follow-up. OUTLINE: Patients undergo hypo-fractionated radiotherapy over 3 weeks in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 1, 3, and 6 months and then at 1, 2, and 3 years.

Design outcomes

Primary

MeasureTime frameDescription
Change in Toxicity - Bowel Summary Scorefrom baseline to the week 3 timepoint, up to 6 weeks from the baseline visitChange in toxicity will be measured by the change in bowel domain score as assessed on the Expanded Prostate Cancer Index Composite (EPIC) instrument. EPIC is a 26-item, self-assessed questionnaire rated on a 5-point Likert scale. 14 items in this assessment create the Bowel Summary score. Bowel Summary scores are transformed linearly to a 0-100 scale, with higher scores indicating better Health-related Quality of Life (HRQOL) and lower scores indicating worse HRQOL. This outcome measure will report mean change in the Bowel Summary Score. A positive change indicates the scores increased (improved HRQOL) and a negative Change indicates the scores decreased (worse HRQOL). This outcome measure will report mean EPIC Bowel Summary scores at the week 3 timepoint.
Trial Feasibility - Number of Evaluable PatientsBaseline to week 3 (up to 6 weeks from the baseline visit)To assess the feasibility of administering a clinical trial to evaluate hypofractionated radiotherapy. This outcome measure will report the number of evaluable patients and the number of patients who started study treatment but were not deemed evaluable. To be considered evaluable, an eligible patient must have completed 3 weeks of treatment and completed EPIC bowel domain questionnaire at baseline and 3 weeks.

Secondary

MeasureTime frameDescription

EPIC is a 26-item, self-assessed questionnaire rated on a 5-point Likert scale. 10 items in this assessment create the Urine Summary score. Urine Summary scores are transformed linearly to a 0-100 scale, with higher scores indicating better Health-related Quality of Life (HRQOL) and lower scores indicating worse HRQOL. This outcome measure will report mean change in the Urine Summary Score. A positive change indicates the scores increased (improved HRQOL) and a negative Change indicates the scores decreased (worse HRQOL). This outcome measure will report mean EPIC Urine Summary scores at the week 3 and 1 year timepoint.
