Background & objective: Cervical adenosquamous carcinoma is a special histological type of cervical carcinoma. Its clinic-pathologic characteristics and prognostic factors have seldom been reported. This study was to explore the clinic-pathologic characteristics and prognostic factors of cervical adenosquamous carcinoma.
Methods: Clinical data of 83 pathologically confirmed adenosquamous cervical carcinoma patients in Sun Yat-sen University Cancer Center from Nov. 1982 to May 2006 were analyzed.
Results: The median overall survival (OS) of 83 patients was 47 months and the median disease-free survival was 43 months. The 5-year survival rate was 74.0%, and the recurrence rate (DFS) was 30.1% (25/83). The median OS and DFS were 58 months and 54 months versus 37 months and 21 months in patients with or without lymph node metastasis (P=0.005, P<0.001). The median DFS was 47 months and 16 months for patients with the tumor diameter >4 or < or =4 cm (P=0.015), respectively. Lymph node metastasis was correlated to FIGO stage, tumor diameter and invasion depth. The recurrence rate of patients with ovarian preservation was 33.3% (3/9).
Conclusions: Lymph node metastasis is an independent risk factor for prognosis in cervical adenosquamous carcinoma. Adjunctive postoperative irradiation would improve the OS and DFS. Tumor diameter greater than 4cm is an independent prognostic risk of DFS. The impact of ovarian preservation on prognosis is unclear.
