Abstract Objective To examine the effect of carcinoma cell type on tumor characteristics, tumor spread, tumor recurrence, and survival of patients with early‐stage cervical cancer who had radical hysterectomy and pelvic lymphadenectomy. Method Data from 499 patients with stage IA to IIA cervical carcinoma who received primary surgical treatment from 2003 to 2005 at Chiang Mai University were retrospectively reviewed with regard to 3 histologic types; squamous cell carcinoma (SCC), adenocarcinoma (AC), and adenosquamous carcinoma (AS). Results Among the 499 patients, 71.1% had SCC, 23.4% had AC, and 5.4% had AS. There was no significant difference in stage, tumor size, tumor characteristics, or rate of loco‐regional spread. A higher proportion of women with SCC needed adjuvant radiation ( P = 0.001). Five‐year recurrence‐free survival (RFS) and overall survival (OS) were comparable among the groups. Among patients with pelvic node metastasis, 5‐year RFS and OS were significantly lower in those with AC than in those with SCC (RFS, 66.1% versus 86.4%, P = 0.02; OS, 68.2% versus 88.2%, P = 0.05). Conclusion There was no difference among SCC, AC, and AS in most tumor characteristics, spread, recurrence, and survival in patients with early‐stage cervical cancer. Among patients with pelvic lymph node metastasis, AC was associated with less favorable outcomes than SCC.
