Diarrhea, Gastrointestinal Complications, Unspecified Adult Solid Tumor, Protocol Specific

About this trial
This is an interventional supportive care trial for Diarrhea focused on measuring diarrhea, gastrointestinal complications, unspecified adult solid tumor, protocol specific
Eligibility Criteria
DISEASE CHARACTERISTICS:
- Diagnosis of cancer that supports the use of radiotherapy to the pelvis
- No current or prior metastases beyond pelvic regional lymph nodes
- Planning to receive a course of continuous definitive or adjuvant external-beam radiotherapy to a minimum dose of 4500 cGy with or without fluorouracil, capecitabine, or oxaliplatin
Planned course of pelvic radiotherapy must fall within the following parameters:
Pelvis must be encompassed by the planned radiotherapy fields
- Superior border may not lie superior to the L4-5 interspace and may not be inferior to the most inferior aspect of the sacroiliac joints
- Portions of the rectum may have special blocking, depending upon disease site
Total planned dose to the central axis midplane (for AP-PA parallel opposed fields) or isocenter (for 3- or 4-field techniques) for the pelvic field must lie between 4500-5300 cGy (inclusive)*
- Subsequent to completion of treatment to the pelvic field, a boost to primary tumor or tumor bed may be planned
Planned treatment is to be given 4-5 times per week on a one-treatment-per-day basis
- Daily dose (specified at central axis midplane or at isocenter for multi-field techniques) must lie between 170-210 cGy (inclusive) per day*
- NOTE: *For institutions that do not use midplane or isocenter as the point for specification of dose, it will be necessary to determine the dose according to the methods specified above in order to determine patient eligibility.
- No perineal irradiation planned (e.g., anal cancer patients, patients who have had an abdominal-perineal resection)
- No brachytherapy planned before the completion of all external-beam radiotherapy
- No planned split-course radiotherapy
