- Registration Number
- NCT05857631
- Lead Sponsor
- Tata Memorial Centre
- Brief Summary
The primary aim of the trial is to investigate the late effects of hypofractionated external radiation (39 Gy in 13 fractions) in patients requiring post-operative radiation for early-stage cervical and endometrial cancers.
- Detailed Description
This is a phase II prospective study that will be accruing patients with post operative cervical or endometrial cancer requiring adjuvant pelvic radiation.
External beam radiotherapy (Intensity modulated radiotherapy/arc technique) will be delivered to pelvis to a dose of 39 Gray (Gy) in 13 fractions at 3 Gy per fraction, delivered once daily over 2.5 - 3 weeks. Treatment will be delivered with Intensity Modulated Radiotherapy (IMRT) under image guidance. Patients for whom concurrent chemotherapy is indicated (as per adverse risk features) will receive concurrent weekly cisplatin (40mg/m2) based on standard institutional protocol. All patients with post-operative cervical cancer will receive vaginal brachytherapy after the completion of external beam radiation. Patients with endometrial cancer with certain pre defined risk factors will also receive vaginal brachytherapy. The dose of vaginal brachytherapy will be 6 Gy high dose rate brachytherapy delivered as two different fractions, one week apart. Patients will be evaluated by the concerned investigators on a weekly basis during radiation therapy and all the toxicities will be documented according to the CTCAE V 5.0.
Patients will be followed up 3 monthly for the first 2 years, then 6 monthly from years 2 - 5, and annually thereafter. CTCAE version 5 will be used for toxicity grading at each follow-up. Quality of life assessment will be performed at baseline prior to the start of radiation and on follow-up at pre-specified times using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (QLQ-C30) and Cervix - 24 (CX24) for cervical cancer patients and Endometrium 24 (EN24) for endometrial cancer patients.

- Primary Outcome Measures
Name Time Method 3-year cumulative incidence of grade ≥2 gastrointestinal or genitourinary toxicity Median follow up of 3 years To evaluate the 3-year cumulative incidence of late grade ≥2 gastrointestinal or genitourinary toxicity using CTCAE version 5 scoring receiving radiation with hypo fractionation.
- Secondary Outcome Measures
Name Time Method Pelvic Control Rate at 3 years Median follow up of 3 years To report 3 year pelvic control rate (local and pelvic nodal) in patients receiving hypofractionated radiotherapy.
Assessment of Quality of Life for cervical cancer patients Median follow up of 3 years To assess quality of life in using EORTC QLQ-C30 and CX24. Quality of life will be measured using the EORTC QLQ C-30. For cervical cancer, EORTC QLQ CX24 module will be used. QOL scoring will be done as per standard recommendations outlined in EORTC QLQ C30 scoring manual. All patients will undergo QOL evaluation at baseline, after treatment and at subsequent follow-up.Scale- Not at all-1 , A little Bit-2, Quite a bit-3, very much-4.
1 will be considered as better outcome \& 4 will be considered as worst outcome.C-MOSES scoring Median follow up of 3 years To report cumulative toxicity score as assessed by C-MOSES scoring. Month and Severity Score (MOSES) will be calculated for each symptom (13 gastrointestinal and 6 genitourinary) with time weighted CTCAE toxicity, by using duration of time spent in each toxicity. Cumulative-MOSES score will be assessed for organ system (gastrointestinal and genitourinary), by summating MOSES of individual adverse event items respectively.
Disease Free Survival at 3 years Median follow up of 3 years To report 3 year disease free survival in patients receiving hypo fractionated radiotherapy.
Overall Survival at 3 years Median follow up of 3 years To report 3 year overall survival in patients receiving hypo fractionated radiotherapy.
Acute Toxicities Evaluation 3 months Acute toxicity will be reported using CTCAE V. 5.0
Assessment of Quality of Life for endometrial cancer patients Median follow up of 3 years To assess quality of life in using EORTC QLQ-C30 and EN24. Quality of life will be measured using the EORTC QLQ C-30. For endometrial tumours, EORTC QLQ EN24 will be used. QOL scoring will be done as per standard recommendations outlined in EORTC QLQ C30 scoring manual. All patients will undergo QOL evaluation at baseline, after treatment and at subsequent follow-up.Scale- Not at all-1 , A little Bit-2, Quite a bit-3, very much-4.
1 will be considered as better outcome \& 4 will be considered as worst outcome.
