Aim:
To demonstrate how workshop and mentoring across a network of radiotherapy centers helped in transitioning from point A to volume-based image guided brachytherapy in carcinoma cervix.
Materials And Methods:
Based on discussion with different centers across the network, the lapses in cervical cancer treatment were identified and a workshop was designed to change the practice pattern. The main focus of the workshop was to streamline EBRT dose prescription protocols and implement volume based image guided brachytherapy through mentoring and hands on training. Patient data was analyzed 1 year post workshop to assess the impact in changing practice pattern.
Results:
A total of 246 cervical cancer patients treated with radical chemo radiotherapy and image guided brachytherapy were analyzed. 207 patients received CT based intracavitary brachytherapy whereas 39 patients received MR based hybrid brachytherapy. In patients who received EBRT and brachytherapy at the same center, the EBRT prescription dose was 45Gy in 25 fractions in 95% patients. The mean dose received by 90% of the HRCTV was 80.8Gy EQD2 in CT based intracavitary brachytherapy and 89.48Gy EQD2 in MR based hybrid brachytherapy. The mean bladder, rectum, sigmoid and small bowel D2cc doses were 63.87Gy, 62.18Gy, 61.2Gy and 55.1Gy EQD2 respectively.
Conclusion:
This report demonstrates successful implementation and change of carcinoma cervix treatment practice pattern through workshop and mentoring across a network of radiotherapy centers in India.
