Acute Gastrointestinal Toxicity, as Measured by Change in Expanded Prostate Cancer Index Composite (EPIC) Bowel Domain Score at 5 Weeks From the Start of Pelvic Radiation [ Time Frame: Baseline and week 5 of RT ]
The primary endpoint is change in acute GI toxicity, as measured by the EPIC bowel domain, from baseline to 5 weeks after the first fraction of radiation is delivered. The EPIC has four domains (bowel, urinary, sexual, and hormonal) that have been validated separately, which allows use of only the domains of interest. The EPIC bowel domain consists of 14 items and has a function subscale (7 items) and bother subscale (7 items). For each domain, responses form a Likert scale and multi-item scale scores are transformed linearly to a 0-100 scale, where higher scores correspond to better quality of life. At least 80% of the items in a domain or subscale of the domain must be completed in order to compute the score. Change was calculated as follow-up score - baseline score so a negative change score indicates a decline in function.

  • Validation of EPIC Bowel and Urinary Domains [ Time Frame: Before study start, Week 3 of RT, Week 5 of RT, 4-6 Weeks after RT, 1 year from start of RT and 3 years from start of RT ]
    Since the EPIC has not been validated in this patient population, a secondary endpoint is to validate the bowel and urinary domains of EPIC in women undergoing either IMRT pelvic radiation treatment or four field pelvic radiation treatments for endometrial or cervical cancer. The bowel and urinary domains of the EPIC can be administered individually since they are separate and distinct modules of the robust and comprehensive EPIC tool.
  • Percentage of Patients With Acute Grade 2+ GI Toxicity at 5 Weeks From the Start of Treatment [ Time Frame: Baseline to Week 5 of RT ]
    Adverse events are graded using CTCAE v4.0. Grade refers to the severity of the AE. The Common Terminology Criteria for Adverse Events (CTCAE) v4.0 assigns Grades 1 through 5 with unique clinical descriptions of severity for each AE based on this general guideline: Grade 1 Mild AE, Grade 2 Moderate AE, Grade 3 Severe AE, Grade 4 Life-threatening or disabling AE, Grade 5 Death related to AE.
  • Urinary Toxicity, as Measured by Change in EPIC Urinary Domain [ Time Frame: Baseline, week 3 and 5 of RT, and 4-6 weeks after RT ]
    The primary endpoint is change in acute GI toxicity, as measured by the EPIC urinary domain, from baseline to 5 weeks after the first fraction of radiation is delivered. The EPIC has four domains (bowel, urinary, sexual, and hormonal) that have been validated separately, which allows use of only the domains of interest. The EPIC urinary domain consists of 12 items and has a function subscale (5 items) and bother subscale (7 items). For each domain, responses form a Likert scale and multi-item scale scores are transformed linearly to a 0-100 scale, where higher scores correspond to better quality of life. At least 80% of the items in a domain or subscale of the domain must be completed in order to compute the score. Change was calculated as follow-up score - baseline score so a negative change score indicates a decline in function.
  • Quality of Life, as Measured by Change From Baseline in Functional Assessment of Cancer Therapy-General (FACT-G) and FACT-Cx (Cervix) Subscale [ Time Frame: Before study start, Week 5 of RT, 4-6 Weeks after RT, 1 year from start of RT and 3 years from start of RT ]
    The FACT-G is a validated, 27-item measure where a higher score represents higher QOL. In addition to a total QOL score, subscale scores for physical, functional, social and emotional well-being are produced. There are 5 responses options, with 0=Not a lot and 4=Very much. All items in a subscale are added together to obtain subscale totals. Scores range from 0-108 for the FACT-G total score, 0-28 for physical, social, functional, and 0-24 for emotional subscale. Certain items must be reversed before it is added by subtracting the response from 4. Subscale totals are summed to form the FACT-G total score. The FACT-Cx is 5-items, with score ranging 0-60, but is not included in total FACT-G. Each subscale requires >= 50% of items completed and overall response rate must be greater than 80%. If items are missing, the subscale scores can be prorated. Change calculated as follow-up score - baseline score so that a negative change score indicates a decline in function.
  • Health Utilities, as Measured by Change From Baseline in EQ-5D [ Time Frame: Baseline, week 5 of RT, 4-6 weeks after RT ]
    The EQ-5D is a 2-part self-assessment questionnaire. First part is 5 items (mobility, self care, usual activities, pain/discomfort, anxiety/depression) each with 3 problem levels (1-none, 2-moderate, 3-extreme). Health states are defined by the combination of the leveled responses to the 5 dimensions, generating 243 health states to which unconsciousness and death are added. The 2nd part is a visual analogue scale (VAS) valuing current health state, measured on a 20-cm 10-point interval scale. Worst imaginable health state is scored as 0 at the bottom of the scale, and best imaginable health state is scored as 100 at the top. Both the 5-item index score and the VAS score are transformed into a utility score between 0 (worst health state) and 1 (best health state). Change from baseline is calculated as score at the timepoint of interested - baseline score.
  • Local-regional Control [ Time Frame: From randomization to 3 years. (Patients are followed until death or study termination, whichever occurs first.) ]
    Local recurrence is defined as a disease in the radiation treatment field. This can include a local vaginal recurrence or nodal disease within the field. Para-aortic recurrence is defined as new lymphadenopathy in the para-aortic distribution. Local-regional control time is defined as time from randomization to the date of local recurrence, last known follow-up (censored), or death (competing risk). Local-regional control rates are estimated using the cumulative incidence method.
  • Disease-free Survival [ Time Frame: From randomization to 3 years. (Patients are followed until death or study termination, whichever occurs first.) ]
    Disease (progression) is defined as local recurrence, para-aortic recurrence, or distant metastasis. Local recurrence is defined as a disease in the radiation treatment field. This can include a local vaginal recurrence or nodal disease within the field. Para-aortic recurrence is defined as new lymphadenopathy in the para-aortic distribution. Distant metastasis is defined as involvement of another organ or peritoneal disease. Evidence of distant metastases or new lymphadenopathy on surveillance imaging should be biopsied if possible to document disease recurrence. Disease-free survival time is defined as time from randomization to the date of progression, death, or last known follow-up (censored). Disease-free survival rates are estimated using the Kaplan-Meier method.
  • Overall Survival [ Time Frame: From randomization until 3 years. (Patients are followed until death or study termination, whichever occurs first.) ]
    Overall survival time is defined as time from randomization to the date of death from any cause and is estimated by the Kaplan-Meier method. Patients last known to be alive are censored at the date of last contact.
  • Identification of Molecular Predictors of Radiation Toxicity and Novel Circulating Cancer Biomarkers [ Time Frame: Tissue samples will be obtained at the time of diagnosis and during the third week of radiation ]

Standard Versus Intensity-Modulated Pelvic Radiation Therapy in Treating Patients With Endometrial or Cervical Cancer
A Randomized Phase III Study of Standard vs. IMRT Pelvic Radiation for Post-Operative Treatment of Endometrial and Cervical Cancer (TIME-C)

RATIONALE: Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue.

PURPOSE: This randomized phase III trial is studying two different methods of radiation and their side effects and comparing how well they work in treating endometrial and cervical cancer after surgery.

OBJECTIVES:

Primary

  • To determine if pelvic intensity-modulated radiation therapy (IMRT) reduces acute gastrointestinal toxicity in the 5th week (after 23-25 fractions) of pelvic radiation as measured with the expanded prostate cancer index composite (EPIC) instrument.

Secondary

  • To determine if grade 2+ gastrointestinal toxicity (Common Terminology Criteria for Adverse Events version 4.0 [CTCAE v. 4.0]) is reduced with IMRT compared to conventional whole-pelvis radiation therapy (WPRT).
  • To determine if grade 2+ hematologic toxicity (CTCAE v. 4.0) is reduced with IMRT compared to conventional WPRT.
  • To determine if urinary toxicity is reduced with IMRT using the EPIC urinary domain.
  • To validate EPIC bowel and urinary domains in women undergoing either IMRT pelvic radiation treatment or four-field pelvic radiation treatment for endometrial or cervical cancer.
  • To assess the impact of pelvic IMRT on quality of life using the Functional Assessment of Cancer Therapy-General (FACT-G) with cervix subscale.
  • To determine if there is any difference in local-regional control, disease-free survival, and overall survival between patients treated with IMRT as compared to conventional WPRT.
  • To perform a health-utilities analysis to measure the financial impact of pelvic IMRT via the EQ-5D instrument.
  • To identify molecular predictors of radiation toxicity and novel circulating cancer biomarkers.

OUTLINE: This is a multicenter study. Patients are stratified according to type of cancer (endometrial vs cervical), chemotherapy (none vs 5 courses of weekly cisplatin at 40 mg/m²), and radiation dose (45 Gy vs 50.4 Gy). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients undergo standard (3-dimensional) radiation therapy 5 days a week for up to 5-6 weeks.
  • Arm II: Patients undergo intensity-modulated radiation therapy (IMRT) 5 days a week for up to 5-6 weeks.

Some patients receive cisplatin IV over 1 hour on day 1. Treatment continues weekly for 5 weeks, concurrently with radiation therapy, in the absence of unacceptable toxicity or disease progression.

Tissue and blood samples may be collected for biomarker and correlative analysis.

Quality of life may be assessed by questionnaires (including the Expanded Prostate Cancer Index Composite [EPIC], the Functional Assessment of Cancer Therapy-General [FACT-G, Version 4], the EQ-5D, and the Common Toxicity Criteria Adverse Events - Patient-Reported Outcome [PRO-CTCAE]) instruments at baseline and periodically during and after study therapy.

After completion of study therapy, patients are followed every 6 months for the first 2 years and then annually for 5 years.
