Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective non-randomized clinical trial to evaluate the feasibility of 3 fraction versus a standard 4 fraction high dose rate brachytherapy regimen in patients with locally advanced cervical cancer.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

3-Fraction Brachytherapy Arm

Patients who meet dosimetric criteria at the first brachytherapy session (HR CTV D90 \> 85 Gy and acceptable OAR constraints) will receive an investigational 3-fraction HDR brachytherapy regimen (24 Gy total).

Group Type EXPERIMENTAL

3-Fraction HDR Brachytherapy

Intervention Type RADIATION

8 Gy per fraction for 3 fractions (total 24 Gy) for patients with locally advanced cervical cancer, based on individualized planning.

Investigational Treatment

Patients who do not meet dosimetric criteria for the investigational regimen will receive the institutional standard-of-care regimen of 4 fractions (28 Gy total).

Group Type ACTIVE_COMPARATOR

4-Fraction HDR Brachytherapy

Intervention Type RADIATION

7 Gy per fraction for 4 fractions (total 28 Gy) as the standard-of-care brachytherapy regimen.
