Abstract
Background Testing for high-risk human papillomavirus DNA (HPV test) has gained increasing acceptance as an alternative method to cytology in cervical cancer screening. Compared to cytology, HPV test has a higher sensitivity for the detection of histologic high-grade squamous intraepithelial lesion or worse (HSIL+), but this could lead to a large colposcopy burden. Genotyping for HPV16/18 has been recommended in triaging HPV-positive women. This study was aimed to evaluate the screening performance of HPV testing and the role of genotyping triage in Northern Thailand. Methods A population-based cervical screening program was performed in Chiang Mai (Northern Thailand) using cytology (conventional Pap test) and HPV test (Hybrid Capture 2). Women who had abnormal cytology or were HPV-positive were referred for colposcopy. Cervical samples from these women were genotyped using the Linear Array assay. Results Of 5,456 women, 2.0% had abnormal Pap test results and 6.5% tested positive with Hybrid Capture 2. Of 5,433 women eligible for analysis, 355 with any positive test had histologic confirmation and 57 of these had histologic HSIL+. The sensitivity for histologic HSIL+ detection was 64.9% for Pap test and 100% for Hybrid Capture 2, but the ratio of colposcopy per detection of each HSIL+ was more than two-fold higher with Hybrid Capture 2 than Pap test (5.9 versus 2.8). Genotyping results were available in 316 samples. HPV52, HPV16, and HPV58 were the three most common genotypes among women with histologic HSIL+. Performance of genotyping triage using HPV16/18/52/58 was superior to that of HPV16/18, with a higher sensitivity (85.7% versus 28.6%) and negative predictive value (94.2% versus 83.9%). Conclusions In Northern Thailand, HPV testing with genotyping triage shows better screening performance than cervical cytology alone. In this region, the addition of genotyping for HPV52/58 to HPV16/18 is deemed necessary in triaging women with positive HPV test.

Abstract
Persistent human papillomavirus (HPV) infection may promote carcinogenesis by hyperactivation of the immune system. We, therefore, explored the associations between HPV infection and risk of Hodgkin and non-Hodgkin lymphoma in a nationwide cohort study using conization as a surrogate marker. We identified all Danish women who underwent conization between 1978 and 2011. We computed standardized incidence ratios and 95% confidence intervals for Hodgkin and non-Hodgkin lymphoma based on national cancer incidence rates. Among 87 435 women who underwent conization, we noted an increased incidence of Hodgkin (standardized incidence ratio 1.48, 95% confidence interval 1.05-2.02) but only a slight increase for non-Hodgkin lymphoma (standardized incidence ratio 1.10, 95% confidence interval 0.97-1.25). As measured by conization, HPV infection is associated with an increased risk of lymphoma. This association may be attributable to a chronic immune activation induced by persistent HPV infection and/or failure of the immune system both to clear HPV infection and to control lymphoma development.

Abstract
Human papillomavirus (HPV) infection is an important cause of cervical cancer. Screening with cytology or combined cytology and HPV testing helps to detect early cervical cancers and precancerous lesions (high-grade squamous intraepithelial lesion or worse [HSIL+]). Minor cytological abnormalities (atypical squamous cells of undetermined significance and low-grade squamous intraepithelial lesion) account for the majority of abnormal cervical cytology results, but only 10-20% of women with minor cytological abnormalities have histologic HSIL+. Triage tests are useful to identify the high-risk patients and reduce the colposcopy burden. This study was aimed to evaluate the triage performance of combined HPV DNA testing and genotyping. Cervical samples from women with minor cytological abnormalities, who underwent colposcopy at Chiang Mai University Hospital in northern Thailand between October 2010 and February 2014, were tested for HPV DNA using Hybrid Capture 2 (HC2). Genotyping was performed using Linear Array assay. Of 223 women with cervical histology confirmation, histologic HSIL+ was detected in 25 women (11.2%). The sensitivity, specificity, positive predictive value, and negative predictive value of 3 triage methods for histologic HSIL+ were; 100%, 47.5%, 19.4%, and 100% by HC2 only; 40.0%, 88.4%, 30.3%, and 92.1% by combined HC2 and genotypes HPV16/18; and 96.0%, 75.8%, 33.3%, and 99.3% by combined HC2 and genotypes HPV16/18/52/58. Triage using combined HC2 and genotypes HPV16/18/52/58 showed significantly greater area under the receiver operating curve than the other 2 methods (P < 0.001). Combined HPV DNA testing and genotyping for HPV16/18/52/58 is useful for triaging women with minor cervical cytological abnormalities in northern Thailand.

Abstract
Background The study aimed to determine the prognostic impact of clinical and pathological factors on survival among patients with small cell neuroendocrine carcinoma (SNEC), adenocarcinoma (ADC), and squamous cell carcinoma (SCC). Methods Eligible participants were all patients with histologically confirmed cervical cancer treated at Chiang Mai University Hospital between 1995 and 2011. We included all patients with SNEC and randomly enrolled patients with ADC and SCC. We used competing-risk regression analysis to examine the risk of cancer-related death by histological type. Results We included 130 (6.2%) women with SNEC, 346 (16.4%) with ADC, and 1,632 (77.4%) with SCC. Age >60 years (hazard ratio [HR] 4.9, 95% confidence interval [CI] 2.0–12.0) and lymph node involvement (HR 3.0, 95% CI 1.2–7.4) were prognostic factors among surgically-treated patients with SNEC. Deeper stromal invasion (HR 3.6, 95% CI 1.6–8.3) was a prognostic factor in patients with SCC. In patients with advanced SNEC, age >60 years had a strong prognostic impact (HR 2.6, 95% CI 1.0–6.5) while the International Federation of Gynecology and Obstetrics stages III and IV were prognostic factors for patients with advanced stage ADC (HR 2.9, 95% CI 2.0–4.4 and HR 4.5, 95% CI 2.6–7.9, respectively) and SCC (HR 1.7, 95% CI 1.4–2.0 and HR 3.7, 95% CI 2.8–4.9, respectively) compared with the International Federation of Gynecology and Obstetrics stage IIB. Conclusion Clinical and pathological prognostic factors in cervical cancer differed according to histological type. Taking the important prognostic factors for each histological type into consideration may be beneficial for tailored treatment and follow-up planning.

Abstract
BACKGROUND Clarifying the prognostic impact of histological type is an essential issue that may influence the treatment and follow-up planning of newly diagnosed cervical cancer cases. This study aimed to evaluate the prognostic impact of histological type on survival and mortality in patients with cervical squamous cell carcinoma (SCC), adenocarcinoma (ADC) and small cell neuroendocrine carcinoma (SNEC). MATERIALS AND METHODS All patients with cervical cancer diagnosed and treated at Chiang Mai University Hospital between January 1995 and October 2011 were eligible. We included all patients with SNEC and a random weighted sample of patients with SCC and ADC. We used competing-risks regression analysis to evaluate the association between histological type and cancer-specific survival and mortality. RESULTS Of all 2,108 patients, 1,632 (77.4%) had SCC, 346 (16.4%) had ADC and 130 (6.2%) had SNEC. Overall, five-year cancer-specific survival was 60.0%, 54.7%, and 48.4% in patients with SCC, ADC and SNEC, respectively. After adjusting for other clinical and pathological factors, patients with SNEC and ADC had higher risk of cancer-related death compared with SCC patients (hazard ratio [HR] 2.6; 95% CI, 1.9-3.5 and HR 1.3; 95% CI, 1.1-1.5, respectively). Patients with SNEC were younger and had higher risk of cancer-related death in both early and advanced stages compared with SCC patients (HR 4.9; 95% CI, 2.7-9.1 and HR 2.5; 95% CI, 1.7-3.5, respectively). Those with advanced-stage ADC had a greater risk of cancer-related death (HR 1.4; 95% CI, 1.2-1.7) compared with those with advanced-stage SCC, while no significant difference was observed in patients with early stage lesions. CONCLUSION Histological type is an important prognostic factor among patients with cervical cancer in Thailand. Though patients with SNEC were younger and more often had a diagnosis of early stage compared with ADC and SCC, SNEC was associated with poorest survival. ADC was associated with poorer survival compared with SCC in advanced stages, while no difference was observed at early stages. Further tailored treatment-strategies and follow-up planning among patients with different histological types should be considered.
