RTOG-1203 A Randomized Phase III Study of Standard Vs. IMRTt Pelvic Radiation for Post-Operative Treatment of Endometrial and Cervical Cancer (TIME-C)


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.



Inclusion and Exclusion Criteria

  • Pathologically proven diagnosis of endometrial or cervical cancer
  • Patients must have undergone a hysterectomy (total abdominal hysterectomy, vaginal hysterectomy or radical hysterectomy, or total laparoscopic hysterectomy) for carcinoma of the cervix or endometrium within 49 days prior to registration
  • Performance of a bilateral salpingo-oophorectomy will be at the treating surgeon's discretion
  • No positive or close (< 3 mm) resection margins
  • Appropriate stage for protocol entry, including no distant metastases, based upon the following minimum diagnostic workup:
  • History/physical examination within 45 days prior to registration
  • Computed tomography (CT), magnetic resonance imaging (MRI), or positron emission tomography (PET)-CT including the abdomen and pelvis should be performed for initial radiological staging (performed pre
  • or post-surgery within 90 days prior to registration)
  • Imaging performed postoperatively should show no evidence of residual disease
  • Any evidence of malignancy identified on preoperative imaging should have been completely resected surgically prior to protocol treatment
  • Chest x-ray or chest CT must be performed within 90 days prior to registration (unless a PET-CT has been performed)
  • Endometrial cancer:
  • Patients with the following histologic features are eligible for pelvic radiation therapy without weekly cisplatin:
  • Less than 50% myometrial invasion, grade 3 adenocarcinoma without uterine serous carcinoma (USC), or clear cell histology

  • Cervical cancer:
  • Patients with the following pathology findings may be treated with pelvic radiation with or without weekly cisplatin at the treating physician's discretion:
  • Patients with intermediate-risk features including two of the following histologic findings after radical hysterectomy: 1/3 or more stromal invasion, lymph-vascular space invasion or large clinical tumor diameter (> 4 cm)
  • Patients with cervical cancer treated with a simple hysterectomy with negative margins
  • Patients with any of the following criteria following radical hysterectomy are eligible for this study and must receive weekly cisplatin:
  • Positive resected pelvic nodes and para-aortic nodes negative if removed. NOTE: If para-aortic nodes are not removed, CT abdomen or PET CT must demonstrate no evidence of lymphadenopathy.
  • Microscopic parametrial invasion with negative margins
