研究概览
简要总结
The two goals of this study are to establish a standardized method of assessing the pelvic floor for patients undergoing pelvic radiation and to determine the feasibility of inverse-RT planning using MRI to identify dosimetric constraints of the pelvic floor musculature for use in radiation planning. The investigators hypothesize that an exam-based diagnostic tool will provide more information about the areas of injury related to pelvic radiation than patient-reported outcomes, and could be used in future studies of preventive strategies. An exam-based tool will also allow measurement of the pain dose-response to radiation treatment of specific areas, which could be excluded from radiation fields during treatment planning.

研究组 & 干预措施
Single-digit pelvic exam
- Patients will have a pelvic floor muscle exam performed by their gynecologic radiation oncologist prior to treatment, at treatment mid-point (after 3 weeks of treatment), at the end of treatment (after 6 weeks of treatment), and at a follow-up visit 6 months after the end of treatment. Patients will also complete the Pelvic Floor Impact Questionnaire 7 (PFIQ-7), Pelvic Floor Disability Index (PFDI-20), and the EORTC QLQ-CX24 at these time points.
- The patient will also undergo a standard of care MRI prior to starting treatment.

结局指标
主要结局
Comparison of patient-reported symptoms as measured by EORTC QLQ-CX2 compared to findings of single digit pelvic exam
时间窗: Prior to starting treatment, at treatment mid-point (3 weeks after treatment), at end of treatment (after 6 weeks of treatment), and at 6 month follow-up visit after end of treatment
An exam will be considered positive for PFMD if pain at any examined site is reported as greater than or equal to four (\>4) out of 10. The EORTC QLQ-CX2 contains 24 items scored 1-4 by frequency with which the patient experiences each. The minimum possible score is 24, and maximum 96, with higher scores indicating worse quality of life. The questionnaire will be considered positive if any vaginal, sexual, or genitourinary module question is rated 4 and otherwise will be analyzed as a continuous variable.
Comparison of patient-reported symptoms as measured by PFIQ-7 compared to findings of single digit pelvic exam
时间窗: Prior to starting treatment, at treatment mid-point (3 weeks after treatment), at end of treatment (after 6 weeks of treatment), and at 6 month follow-up visit after end of treatment
An exam will be considered positive for PFMD if pain at any examined site is reported as \>4 out of 10. The PFIQ-7 includes 7 items each repeated across three domains and provides a scaled score and total score indicating how much a patient is bothered by pelvic floor-related issues. The questionnaire does not have an established severity scale, and therefore will be analyzed as a simple continuous variable.
Comparison of patient-reported symptoms as measured by PFDI-20 compared to findings of single digit pelvic exam
时间窗: Prior to starting treatment, at treatment mid-point (3 weeks after treatment), at end of treatment (after 6 weeks of treatment), and at 6 month follow-up visit after end of treatment
An exam will be considered positive for PFMD if pain at any examined site is reported as \>4 out of 10. The PFDI-20 includes 20 items in three domains and provides a scaled score of 0-100 indicating how much a patient is bothered by pelvic floor-related issues. The questionnaire will be considered positive if the scaled score is greater than or equal to 16, indicating at least "moderate distress" and otherwise will be analyzed as a continuous variable.
