Официальное название
A Prospective Multicentre Phase III Randomised Open Clinical Study of Early Stage Endometrial Cancer Based on Molecular Classification and Traditional Risk Stratification to Guide Adjuvant Radiotherapy Decisions
Обзор
The purpose of this study is to compare the efficacy and toxicity of early stage endometrial cancer based on molecular classification and conventional risk stratification adjuvant therapy decision-making, and to provide high-quality evidence-based medical evidence for individualized adjuvant therapy selection under the guidance of fine stratification system of endometrial cancer.
Подробное описание
This is an investigator-initiated prospective, national multicentre, phase III, randomised, open, non-inferiority clinical study. The study hypothesis is that adjuvant radiotherapy decision for early-stage endometrial cancer which is based on molecular classification can achieve de-escalation of adjuvant treatment without reducing local tumour control and survival, thereby potentially further reducing radiotherapy-related toxicity and improving quality of life, compared to using conventional risk stratification. The primary endpoint of this study is the 3-year local recurrence rate.
Вмешательства
- Лучевая терапия Vaginal brachytherapy
High-dose rate vaginal brachytherapy (VBT) was delivered with a vaginal cylinder.For VBT administered alone, the dose is recommended: 3 fractions of 7 Gy or 5 fractions of 6 Gy or 6 fractions of 5 Gy. For VBT administered after completion of EBRT: 2-3 fractions of 4-6 Gy. - Лучевая терапия Pelvic external beam radiotherapy
EBRT was delivered to the pelvic area using a total dose of 45-50.4Gy in 25-28 fractions over 5-6 weeks with the intensity-modulated radiotherapy (IMRT) technique, three-dimensional conformal radiotherapy (3D-CRT) modality - Другое Observation
No radiotherapy is administrated, but active follow-up and quality of life questionnaires is needed after surgery. - Препарат Chemotherapy
Intravenous concurrent or sequential adjuvant chemotherapy consists of carboplatin/paclitaxel, cisplatin/doxorubicin or cisplatin/doxorubicin/paclitaxel, etc.
