Abstract

Management of recurrent cervical cancer by reirradiation after radiation treatment remains controversial. In Indonesia, there is currently no data about reirradiation tumor response and side effects. This study aims to assess the tumor response to and side effects of reirradiation, the effect of time interval between first radiation treatment and cancer recurrence on the tumor response and side effects, and the effect of tumor size on tumor response. A cohort retrospective study with no comparison was done with the Radiotherapy Department at Cipto Mangunkusumo General Hospital, Jakarta. Participants were recurrent cervical cancer patients undergoing reirradiation. Data was collected from patients' medical records and follow-up phone calls. Twenty-two patients participated in this study. Nine patients (40.9%) had complete responses, 10 patients (45.5%) had partial responses, 1 patient (4.5%) had a stable response, and 2 patients (9.1%) had tumor progressions. In general, 15 patients (68.2%) had no to light side effects (grade 0-2 RTOG) and 7 patients (31.8%) had severe side effects (grade 3-4 RTOG). Four patients (18.1%) had severe gastrointestinal acute side effects, 6 patients (27.3%) had severe gastrointestinal late side effects, 2 patients (9.1%) had severe urogenital side effects, and there were no patients had severe urogenital late side effects. There was no significant difference in tumor response between patients with time interval between first radiation treatment and recurrence of <12 months vs. ≥12 months. There was no significant difference in tumor response between patients with tumor size ≤4 cm vs. >4 cm. Reirradiation can be considered as a modality in recurrent cervical cancer management since good tumor response was achieved and the majority of patients had no to light side effects (grade 0-2 RTOG). This study found no correlation between tumor response, side effects, and time gap between first radiation treatment and recurrence of <12 months vs. ≥12 months. There was also no correlation between tumor response and tumor size of ≤4 cm vs. > 4 cm.
