Abstract :

We fi rst established our methodology using SPF1/GP6+ PCR followed by hybridization with a genechip (Easychip� HPV Blot, King Car, Taiwan) for paraffi n-embedded tissue. Consecutive patients treated for cervical carcinoma of International Federation of Gynecology and Obstetrics stage I?IV between 1993 and 2000 were included. A total of 2,118 patients were eligible for analysis. HPV DNA sequences were detected in 96?6% of the specimens, among which 82% harbored single-type and 18% contained multiple-type HPV sequences. Th e leading 5 were: HPV16 (50?0%), HPV18 (17?8%), HPV58 (16?3%), HPV33 (8?7%), and HPV52 (6?8%). Th e relation of HPV genotype to prognosis of invasive cervical cancer has been controversial. Our study off ered a conclusion on (n=1067) this issue. By multivariate analysis, FIGO stage, lymph node metastasis, depth of cervical stromal invasion, grade of diff erentiation, and HPV 18-positivity were signifi cantly related to cancer relapse. FIGO stage II, deep stromal invasion, parametrial extension, HPV 18-positivity, and age older than 45 were signifi cant predictors for death. Using the seven selected variables from either recurrence-free or overall survival analysis, death and relapse predicting models classifying three risk groups (low-risk, intermediate-risk, and high-risk) were constructed and endorsed by internal validation. Th e prognostic models could be useful in counseling patients and stratifying subjects in future clinical trials. Among the 992 patients treated with primary radiotherapy, the high-risk group consisted of the patients without HPV infection or the ones infected with the alpha-7 species only in addition to stage, lymph node metastasis, histologic type and squamous cell carcinoma antigen.
