Background No standard treatment exists for patients with recurrent cervical cancer. This study aimed to determine the role of surgery, followed by concurrent radiochemotherapy, as a treatment for recurrent pelvic cervical cancer without previous radiotherapy. Methods The current study identified patients diagnosed with vaginal and/or pelvic sidewall recurrent cervical cancer after primary surgery without radiotherapy in Zhejiang Cancer Hospital from May 2012 to November 2016. These enrolled patients underwent surgery, followed by concurrent radiochemotherapy and data were analyzed. Results This study enrolled 27 patients, including 11 with central (vaginal) and 16 with noncentral (pelvic sidewall with or without vaginal) recurrences. The median follow-up time after recurrence was 64 months (range, 5–110 months). All patients underwent surgery to resect the tumor as completely as possible and pelvic external beam radiotherapy (EBRT) with a median equivalent dose in 2 Gy fractions (EQD2) of 45.1 Gy (range, 44.3–47.8 Gy) with concurrent weekly cisplatin chemotherapy. The median EQD2 dose for the tumor bed/residual tumor was 51 Gy (range, 44.3–73.4 Gy), including 18 patients with a boost dose by EBRT or vaginal brachytherapy (VBT). The 5-year overall survival (OS) rates were 77.1% (central) and 65.7% (noncentral) without a statistically significant difference (P=0.246). Progression-free survival (PFS) rates were 81.8% (central) and 34.4% (noncentral), respectively, with a statistically significant difference (P=0.047). Three patients with noncentral recurrence experienced grade ≥3 complications associated with surgery. Conclusions Surgery followed by concurrent radiochemotherapy was a feasible and effective treatment with acceptable complications for locally recurrent cervical cancer, which markedly improved the survival of pelvic sidewall recurrence.
