INTRODUCTION: Neuroendocrine carcinoma of the cervix (NECC) is an aggressive disease with high rates of nodal disease spread even in seemingly cervix-confined disease. Many providers routinely prescribe postoperative radiation therapy in an effort to reduce recurrences despite a lack of supporting studies. The objective of this study was to determine recurrence and mortality in patients with early-stage NECC who had pelvic radiation after radical hysterectomy compared to those who did not receive radiation.
METHODS: We performed a meta-analysis of 13 unique studies that reported recurrence and/or mortality for patients with early-stage NECC who underwent radical hysterectomy with or without adjuvant radiation therapy.
RESULTS: In 5 studies that reported overall recurrence rates, 63 (52.5%) of 120 patients who received postoperative radiation recurred compared to 70 (37.8%) of 185 patients who did not (RR 1.21, 95% CI: 0.85-1.70, p = 0.29). In 5 studies that reported pelvic recurrence rates, there were 15 pelvic recurrences (12.5%) in the 120 patients who received postoperative radiation compared to 45 pelvic recurrences (24.3%) in the 185 patients who did not (RR 0.60, 95% CI: 0.34-1.08, p = 0.09). In 13 studies that reported mortality rate, there were 138 deaths (34.8%) in 396 patients who received postoperative radiation therapy compared to 223 (35.2%) in 632 patients who did not (RR 1.08, 95% CI: 0.75-1.56, p = 0.66).
CONCLUSIONS: The addition of routine postoperative radiation therapy in all patients with early-stage NECC after radical hysterectomy may reduce pelvic recurrences but does not appear to decrease overall recurrence or death. However, there may still be a role for postoperative radiation therapy in patients with additional high-risk pathologic factors.
