Abstract Aim: To compare the clinical efficacy focused on post‐treatment morbidity between adjuvant chemotherapy (CT) and pelvic radiotherapy (RT) after radical hysterectomy for patients with cervical cancer. Methods: A total of 125 patients with cervical squamous cell carcinoma who underwent radical hysterectomy and pelvic lymphadenectomy at Hokkaido University Hospital between 1991 and 2002 were enrolled in the study for retrospective analysis. Seventy patients with recurrent risk factors, including deep stromal invasion, lymph vascular space invasion, parametrial invasion, lymph node metastasis (LNM), and bulky tumor (≥4 cm), received adjuvant therapy; 42 were treated with RT, and 28 were treated with CT. Almost all patients with multiple LNM received RT. Analyses were also performed on a subgroup of 50 patients without multiple LNM (23 RT, 27 CT). Clinical efficacy of post‐treatment morbidity and survival was evaluated. Results: Because there were more patients with multiple LNM in the RT group, we analyzed disease‐free survival in 50 patients without multiple LNM. The 3‐year disease‐free survival rate was 82.6% with RT and 96.3% with CT ( P = 0.16). Postoperative bowel obstruction was significantly more frequent in the RT group versus the CT ( P = 0.007) and no‐therapy ( P = 0.0026) groups. Urinary disturbance was also more frequent in the RT group than in the CT ( P = 0.0016) and no‐therapy ( P = 0.089) groups. Conclusion: CT has the equivalent therapeutic effect as RT with fewer postoperative complications for patients with intermediate risks. A prospective randomized trial is needed to compare CT combined with radical hysterectomy and pelvic lymphadenectomy to RT or chemoradiotherapy.
