Objective To investigate the safety of concurrent chemoradiotherapy after Type 3 radical hysterectomy, focusing on non-hematologic toxicity. Methods Between January 2010 and December 2017, 236 patients diagnosed with cervical cancer Stages IB1–II (FIGO2008) and who had undergone Type 3 radical hysterectomy at the Jikei Medical University School-related four hospitals were included. Of these 236 patients, 134 had undergone adjuvant concurrent chemoradiotherapy after Type 3 radical hysterectomy (radical hysterectomy + concurrent chemoradiotherapy group), and 102 received no adjuvant therapy after Type 3 radical hysterectomy (radical hysterectomy group). The frequency of non-hematologic toxicities, especially lymphedema, pelvic infection, renal dysfunction, ileus and diarrhea, was investigated in the radical hysterectomy + concurrent chemoradiotherapy and radical hysterectomy groups using univariate and multivariate analyses. In these analyses, age, extent of lymph node dissection and preoperative clinical stage were included as risk factors for five complications. The risk factors for grade ≤ 2 adverse events were statistically evaluated. Results The frequency of lower extremity lymphedema (22 vs. 10%), renal dysfunction (13 vs. 3%), and diarrhea (13 vs. 0%) was significantly higher in the radical hysterectomy + CRRT group than that in the radical hysterectomy group. Logistic regression analysis revealed that adjuvant concurrent chemoradiotherapy significantly affected the occurrence of grade ≥ 2 lymphedema (P < 0.01) and renal dysfunction (P < 0.01). Conclusions Concurrent chemoradiotherapy after Type 3 radical hysterectomy is associated with a higher incidence of renal dysfunction, lower extremity lymphedema and diarrhea. A more appropriate adjuvant therapy needs to be established. |
