Background: Cervical human papillomavirus (HPV) infection among young women (20-25 years of age) is common and normally transient. There are growing concerns that referral to a colposcopy clinic may lead to unnecessary treatment with an increased risk of obstetric complications. Therefore, the purpose of this study was to determine the level of intervention for cervical abnormalities in this age group of the Northern Ireland population. Materials and Methods: A review of all serial new patients under 25 years of age, who were referred to colposcopy clinics in Northern Ireland between January 1, 2009 to June 30, 2009 formed the basis of this study. Results: During the study period, a total of 4,767 women under 25 years of age were screened. Two-hundred-and-thirty-four (4.9%) cases were referred to the colposcopy clinics. The cervical cytology results were: high-grade abnormality in 35%, and low-grade abnormality in 31% of these cases. One-hundred-and-seventy-eight (76%) of the referred women received at least one treatment. One-hundred-and-twenty-one of 234 (51.5%) women underwent an excisional treatment with histology showing the presence of high-grade abnormalities (CIN2-3) in 52%, CIN1 in 28%, and Koilocytosis or normal tissue in 20% of this sub-group of cases. Conclusions: Screening women under the age of 25 years cause unnecessary referral for colposcopy. This may also result in considerable anxiety and psychosexual morbidity. It leads to an over-treatment with a potential of negative impact on the future pregnancy outcomes (including pre-term delivery, low birth weight, and pre-term premature rupture of membranes).

Interleukin-6 (IL-6), a central proinflammatory cytokine, maintains immune homeostasis and also plays important roles in cervical cancer. Therefore, we aimed to evaluate any associations of IL-6 gene polymorphisms at positions -174 and -572 with predisposition to cervical cancer in a Chinese population. The present hospital-based case-control study comprised 518 patients with cervical cancer and 518 healthy controls. Polymorphisms of the IL-6 gene were genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Patients with cervical cancer had a significantly higher frequency of the IL-6 -174 CC genotype [odds ratio (OR) =1.52, 95% confidence interval (CI) = 1.06-2.19; p=0.02], IL-6 -572 CC genotype (OR =1.91, 95% CI = 1.16-3.13; p=0.01) and IL-6 -174 C allele (OR =1.21, 95% CI = 1.02-1.44; p=0.03) compared to healthy controls. When stratifying by the FIGO stage, patients with III-IV cervical cancer had a significantly higher frequency of IL-6 -174 CC genotype (OR =1.64, 95% CI =1.04-2.61; p=0.04). The CC genotypes of the IL-6 gene polymorphisms at positions -174 and -572 may confer a high risk of cervical cancer. Additional studies with detailed human papillomavirus (HPV) infection data are warranted to validate our findings.

Purpose: We evaluated the prognostic factors and clinical outcomes of 56 patients with vulvar cancer treated with curative radiotherapy (RT) or concurrent chemoradiotherapy. Materials and Methods: Overall survival (OS) and disease-free survival (DFS) were assessed retrospectively. Prognostic factors evaluated included age, International Federation of Gynecology and Obstetrics (FIGO) stage, TNM classification, tumor size, treatment modality, RT duration, and RT field. The association between the tumor human papillomavirus (HPV) status and survival was analyzed in 35 patients. Results: During the median follow-up of 2.8 years (range, 0.3 to 18.9 years), 21 patients (37.5%) experienced treatment failure. Fifteen patients (27%) had local failure: nine (16%) local failure only, three (5%) locoregional failure, two (4%) local and distant failure, and one (2%) locoregional and distant failure. Of 56 patients, seven (13%) had persistent disease at the first follow-up at 2 months and all but one died within a year after completing RT. The 5-year OS and DFS were 51.6% and 44.0%, respectively. In multivariate analysis, clinical size ${\geq}3$ cm predicted a poor prognostic factor for DFS (p = 0.040) and age (${\geq}70years$) was poor prognostic for DFS (p = 0.032) and OS (p = 0.048). Patients with HPV-positive tumors tended to have better 5-year OS and DFS, but the differences were not significant statistically. Conclusion: Clinical size ${\geq}3$ cm was a significant prognostic factor for DFS. However, age was the most important prognostic factor for DFS and OS in patients treated with curative RT. Further studies are needed to determine which treatment should be considered for old age ${\geq}70years$.

현재 성병은 성매개 질환(sexually transmitted disease, STD)은 무증상 감염도 포함하는 의미에서 "성매개 감염"(sexually transmitted infections, STI)이라고 표현하고 있다. STI는 다양한 상호 관계를 가지고 있다. 본 연구는 보건복지부 장관이 고시하는 STI로 매독, 임질, 클라미디아 감염증, 연성하감, 성기단순포진, 첨규콘딜로마, 사람유두종바이러스 감염증과 비임균성요도염(non-gonococcal urethritis, NGU)을 대상으로 하였다. 따라서 다발성 및 동시성 STI를 확인하여 요인을 특성화하는 것을 목적으로 하였다. 본 연구는 2014년부터 2019년까지 서울에 위치한 일개 수탁검사기관의 검사실정보시스템(laboratory information system)의 자료를 활용하였다. 본 연구에서 다발성 STI로 두 가지 감염균의 중복 STI는 10 종류, 세 가지 감염균의 다중 STI는 6 종류로 나타났다. 이러한 16 종류의 다발성 STI 중 가장 많은 비중을 차지하는 균은 U. urealyticum (9가지), HSV-2 (8가지), C. trachomatis (7가지), HPV 6, 11 (7가지), N. gonorrhoeae (6가지), T. pallidum (1가지)에 포함되었다. 따라서 본 연구 결과에서 다발성 STI에 가장 비중이 높은 STI 등 상호 관계연구의 추가연구가 필요할 것으로 사료된다.

자궁경부암은 전 세계적으로 네번째를 차지하는 여성암이다. 자궁경부암의 대부분 원인은 인유두종 바이러스의 감염이다. 인유두종 바이러스를 검출하기 위해 다양한 분자진단학적 방법들이 고안되었다. 분자진단학적 방법 중의 real-time PCR은 목표 DNA 또는 RNA의 정량과 민감도 향상을 목표로 도입되었다. 특히, real-time PCR 과정은 수행 전에 RNA 추출 및 상보적인 DNA 합성 과정이 필요하다. 따라서 본 연구에서는 민감하고 적합한 상보적인 DNA 합성 키트를 알아보기 위해서 상보적인 DNA 합성에 이용되는 두 개의 상용화된 키트를 평가하였다. 자궁경부암 세포주에서 두개의 상보적인 DNA 합성 키트의 $R^2$과 효율성을 비교한 결과 차이가 없었다. 그러나 Invitrogen 키트보다 Takara 키트가 $10^2$ 및 $10^3$ SiHa 세포주에서 P<0.001를 나타내었고 $10^1$ 및 $10^2$ HeLa 세포주에서도 P<0.001를 나타내었다. 이를 통해 Takara 키트가 Invitrogen키트보다 민감도가 높음을 알 수 있었다. 또한 40개의 탈락세포검체의 8, 4, 2, 1 mL을 이용하여 상보적인 DNA 합성 키트를 비교한 결과 Invitrogen 키트보다 Takara 키트가 8, 4, 1 mL에서 P<0.01 및 0.5 mL에서 P<0.05을 나타내어 임상 검체를 이용하였을 때에도 Takara 키트가 Invitrogen 키트보다 민감도가 높음을 알 수 있었다. 본 연구는 적합한 상보적인 DNA 합성 키트를 확인하기 위해 수행되었으며, 상보적인 DNA 합성 키트가 real-time PCR 결과 다양성에 영향을 미친다는 것을 시사하였다.

Objective: Interferon-${\gamma}$ (IFN-${\gamma}$) and signal transducers and activators of transcription (STATs) each play an important role in carcinogenesis associated with viral infection. Cervical cancer is almost invariably associated with infection by human papillomavirus (HPV), and previous studies suggested that dysregulation of the signal pathway involved in IFN-${\gamma}$ and STATs is associated. Our objective was to evaluate the association of SNPs in STAT2, STAT3, and IFN-${\gamma}$ with cervical cancer susceptibility in Chinese Han women in Hunan province. Materials and Methods: Genomic DNA was extracted from peripheral blood samples of 234 cervical cancer patients and 216 healthy female controls. STAT2 and STAT3 genotyping was performed using polymerase chain reaction-restriction enzyme (PCR-RE) analysis. IFN-${\gamma}$ genotyping was detected by PCR-amplification of specific allele (PASA). Results: For STAT2 rs2066807 polymorphisms, there was no significant difference of genotype distribution (P=0.827) and allele frequencies (P=0.830, OR=1.09, 95% CI: 0.51-2.31) between cases and controls. For STAT3 rs957970 polymorphisms, there was no significant difference of genotype distribution (P=0.455) and allele frequencies (P=0.560, OR=0.92, 95% CI: 0.71-1.20) between cases and controls. For IFN-${\gamma}$ +874A/T polymorphisms, there was no significant difference of genotype distribution (P=0.652) and allele frequencies (P=0.527, OR=1.12, 95% CI: 0.79-1.59) between cases and controls. Conclusion: These results suggest that polymorphisms in STAT2, STAT3 and IFN-${\gamma}$ genes are not likely to be strong predictors of cervical cancer in Han women in southern China.

Objective: The objective of this study was to establish a program model for use in wide-spread cervical cancer screening. :Methods: Cervical cancer screening was conducted in Zhongshan city in Guangdong province, China through a coordinated network of multiple institutes and hospitals. A total of 43,567 women, 35 to 59 years of age, were screened during regular gynecological examinations using the liquid-based ThinPrep cytology test (TCT). Patients who tested positive were recalled for further treatment. Results: The TCT-positive rate was 3.17%, and 63.4% of these patients returned for follow-up. Pathology results were positive for 30.5% of the recalled women. Women who were younger than 50 years of age, urban dwelling, low-income, had a history of cervical disease, began having sex before 20 years of age, or had sex during menstruation, were at elevated risk for a positive TCT test. The recall rate was lower in women older than 50 years of age, urban dwelling, poorly educated, and who began having sex early. Ahigher recall rate was found in women 35 years of age and younger, urban dwelling, women who first had sex after 24 years of age, and women who had sex during menstruation. The positive pathology rate was higher in urban women 50 years of age and younger and women who tested positive for human papillomavirus. Conclusion: An effective model for large-scale cervical cancer screening was successfully established. These results suggest that improvements are needed in basic education regarding cervical cancer screening for young and poorly educated women. Improved outreach for follow-up is also necessary to effectively control cervical cancer.
