Prognostic value of age and histologic type in neoadjuvant chemotherapy plus radical surgery for bulky (≥4 cm) stage IB and IIA cervical carcinoma

The purpose of this study was to investigate pretreatment variables related to prognosis and to evaluate long-term outcome in patients with bulky early-stage cervical carcinoma who were enrolled into a protocol treatment of neoadjuvant chemotherapy (NAC) followed by radical surgery. Between 1988 and 1999, 162 women with previously untreated bulky (≥4 cm) stage IB or IIA carcinoma of the uterine cervix registered to receive cisplatin, vincristine, and bleomycin for three cycles followed by radical hysterectomy and pelvic lymphadenectomy, were enrolled into this study. The 5-year relapse-free (RFS) and overall survival (OS) rates of the whole series were 65% and 69%, respectively. In multivariate analyses, age (< 35 vs. ≥ 35-year-old: relative risk [RR], 2.06; 95% confidence interval [CI], 1.02–4.14; P = 0.043) and histologic type (adeno-adenosquamous vs. squamous carcinoma: RR, 2.60; 95% CI, 1.26–5.39; P = 0.010) were independent variables associated with RFS, and age (< 35 vs. ≥ 35-year-old: RR, 2.53; 95% CI, 1.24–5.14; P = 0.010) and pre-NAC tumor size (> 5 vs. = 5 cm: RR, 2.06; 95% CI, 1.09–3.90; P = 0.027) were significantly related to OS. Narrowing down patient selection to squamous carcinoma and age older than 35 years with stratification of tumor size (break point of 5 cm) is recommended in future trials involving cisplatin-based NAC plus radical surgery.
