Abstract:
Objective To study the clinical and pathological characteristics of HPV-negative cervical cancer patients. Methods Retrospective analysis of 785 cervical cancer patients in Guangdong Women and Children Hospital from Jan. 2005 to Oct. 2015. By detecting high-risk HPV infection by flow-through hybridization genechip technique. Results (1) Among 785 cases of cervical cancer, 71 cases were negative for HPV infection tested by genechip technique, accounting for 9.0%(71/785), and the relative light units/cut off (RLU/CO) ratios of these 71 cases were less than 1 by hybird captureⅡ(HC-Ⅱ) methods. The results showed that the positive coincident rate of genechip technique detecting result with HC-Ⅱmethod was 100.0%(71/71). (2) There was no difference between 43 (60.6%) cases from 41-55 years old of 71 cases of HPV-negative patients and 392 (54.9%) cases from 41-55 years old of 714 cases of HPV infection patients (χ2=15.63, P=0.571). Among 71 cases of HPV-negative patients, 32 cases of patients with doing TCT, 6 (18.8%) cases for normal, 10 (31.2%) cases for atypical squamous cells of undetermined significance (ASCUS), 3 (9.4%) cases for atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion (ASC-H), 3(9.4%) cases for low-grade squamous intraepithelial lesions (LSIL), 8 (25.0%) cases for hight-grade squamous intraepithelial lesions (HSIL), 2 (6.2%) cases for squamous cell carcinoma (SCC). And there were 391 cases of patients with doing thin-prep cytologic test (TCT) of 714 HPV infection patients, 60 (15.3%) cases for normal, 61 (15.6%) cases for ASCUS, 28 (7.2%) cases for ASC-H, 29 (7.4%) cases for LSIL, 164 (41.9%) cases for HSIL, 49 (12.5%) cases for SCC. There was no difference of TCT between HPV infection and HPV-negative patients (P>0.05). Among 70 cases from 71 patients with negative for HPV infection, there were 8(11.4%) cases in stage Ⅰa, 26 (37.1%) cases in stage Ⅰb1, 12 (17.1%) cases in stageⅠb2, 11 (15.7%) cases in stageⅡa, 10 (14.3%) cases in stageⅡb, 3 (4.3%) cases in stageⅢ-Ⅳ. There were 118(16.6%) cases in stageⅠa, 261 (36.8%) cases in stageⅠb1, 72 (10.1%) cases in stageⅠb2, 152 (21.4%) cases in stageⅡa, 87 (12.3%) cases in stageⅡb, 20(2.8%) cases in stageⅢ-Ⅳin 710 cases of HPV infection patients, in which there were no difference of clinical stage between HPV infection and HPV-negative patients (P>0.05). Among 69 cases from 71 patients HPV-negative infection, there were 51 (73.9%) cases for squamous carcinoma, 13 (18.8%) cases for adenocarcinoma, 5(7.2%) cases for adenosquamous carcinoma;and 593 (87.2%) cases for squamous carcinoma, 38 (5.6%) cases for adenocarcinoma, 39 (5.7%) cases for adenosquamous carcinoma, 10 (1.5%) case for others were in 680 patients of HPV infection, in which there was significant difference of adenocarcinoma between HPV infection and HPV-negative patients (χ2=11.96, P=0.001). Conclusions Flow-through hybridization genechip technique is the method of high sensitivity to detect high-risk type HPV, as like HC-Ⅱ method. HPV-negative of cervical cancer occurs mainly in 41-55 years old. Adenocarcinoma incidence is significantly higher in HPV-negative cases than those patients with infection of HPV positive.
