however, grade 3 acute toxicity was noted in 8.1% of the patients. After completion of palliative radiotherapy, 70.6% had a subjective response and 34.2% went on to have further cancer-directed treatment. The median survival after radiotherapy is 6 months and ranged from 1 month to 6 years. Upon analysis of the prognostic factors, the absence of distant metastases (p=0.019) and receipt of further lines of treatment (p=0.045) were found to have a positive influence on the survival after radiotherapy. Qualitative variables like performance status, comorbidities (ACE- 27) and quantitative variables like EQD2 of the radiotherapy schedule, number of metastases or visceral metastases did not significantly associate with survival post palliative radiotherapy.

Conclusion Palliative radiotherapy to the pelvis in advanced FGTC is well tolerated with a majority having a subjective response. Patients with distant metastases who could not receive further lines of oncologic treatment fared significantly poorly. With limited life expectancy in these patients, choice of radiotherapy schedule is key when balancing symptoms and pelvic disease control.
