Postoperative adjuvant therapy in early invasive cervical cancer patients with histopathologic high-risk factors.
The purpose of this study is to evaluate the efficacy of postoperative adjuvant therapy in preventing treatment failure after primary treatment with surgery in early invasive cervical cancer patients associated with the following histopathologic high-risk factors: lymph node metastasis (either macroscopic or microscopic), parametrial extension, lymphovascular permeation and depth of invasion > or =10 mm. Postoperative adjuvant concurrent chemoradiotherapy (PCCRT), postoperative adjuvant chemotherapy (PCT), or postoperative adjuvant radiotherapy (PRT) alone was administered to the 80 early invasive cervical cancers with at least one of the high-risk factors. Each of 61 patients received three to six cycles of chemotherapy at intervals of approximately 3 weeks. Twenty three patients were treated with PCCRT, 38 patients were treated with PCT alone, and 19 patients received PRT. The 5-year survival rates of patients with macroscopic lymph node metastasis were 66.7% and 35.7% in PCCRT and PRT, respectively. With microscopic lymph node metastasis, the 5-year survival rates were 83.3%, 60.0%, and 70.1% in PCCRT, PCT, and PRT, respectively. With parametrial extension, the 5-year survival rate was 58.1% in PCCRT. The 5-year survival rates of patients with lymphovascular permeation were 100%, 90.9%, and 66.7% in PCCRT, PCT, and PRT, respectively. With depth of invasion > or =10 mm, the 5-year survival rates were 100% and 91.3%, in PCCRT and PCT, respectively. PCCRT appears to be superior to PRT or PCT alone in early invasive cervical cancer patients with histopathologic high-risk factors.
