Factors associated with HPV persistence after conization in patients with negative margins
남계헌,정수호,김정식,전섭,배동한 대한부인종양학회 2009 Journal of Gynecologic Oncology Vol.20 No.2
Objective: The clearance rate of human papillomavirus (HPV) after conization is generally high, although some HPV infections persist. We investigated the factors that affect the clearance of HPV after conization in patients with negative margins. Methods: We retrospectively analyzed 77 patients (mean age 39.9 years, range 25 to 51 years) with CIN 2/3 who underwent loop electrosurgical excision procedure (LEEP) conization with negative margins. All patients had a Pap smear and high-risk (HR) HPV testing using Hybrid Capture II system and HPV DNA chip before conization. We used≥1 relative light units (RLUs) as the cutoff for persistence of HPV after conization. Results: High-risk HPV was detected in 73 of 77 (94.8%) patients before conization. At the 6-months follow-up, the high-risk HPV was eliminated in 60 of 73 (82.2%) patients. The HPV persistence rate after conization was 17.8% (13/73). Univariate analysis showed that persistent HPV infection after conization with negative margins was more likely to occur when the pretreatment viral load was high (RLU/positive control >100 (p=0.027) and the HPV was type 16 (p=0.021). Logistic regression analysis showed that preoperative HPV type 16 infection was the only significant independent factor (p=0.021) for HPV persistence out of age, cytology, punch biopsy histology, HPV viral load, and conization histology. Conclusion: Conization effectively removes HR-HPV infection. HPV type 16 infection before conization was significantly related to HR-HPV persistence after conization with negative margins. Therefore, patients with HPV 16 infection before conization need to be followed closely.

Early human papillomavirus testing predicts residual/recurrent disease after LEEP
류애리,남계헌,곽정자,김정식,전섭 대한부인종양학회 2012 Journal of Gynecologic Oncology Vol.23 No.4
Objective: The purpose of this study was to determine the predictive factors for residual/recurrent disease and to analyze the timing for Pap smears and human papillomavirus (HPV) testing during follow-up after loop electrosurgical excision procedure (LEEP) for cervical intraepithelial neoplasia (CIN) 2 or worse. Methods: We retrospectively analyzed 183 patients (mean age, 39.3 years) with CIN 2/3 who were treated with LEEP. Post-LEEP follow-up was performed by Pap smear and HPV hybrid capture2 (HC2) testing. The definition of persistent/recurrent disease was biopsy-proven CIN 2 or worse. Results: Among 183 patients, punch biopsies were CIN 2 in 31 (16.9%) and CIN 3 in 152 (83.1%). HPV HC2 tests before LEEP were positive in 170 (95.5%) of 178 patients. During follow-up, 12 patients (6.6%) had residual/recurrent CIN 2+. LEEP margin status was a significant predictive factor for persistent/recurrent disease. Other factors such as age, HPV HC2 viral load (≥100 relative light units), and HPV typing (type 16/18 vs. other types) did not predict recurrence. Early HPV HC2 testing at 3 months after LEEP detected all cases of residual/recurrent disease. The sensitivity and negative predictive value of the HPV HC2 test for residual/recurrent disease were both 100% at 3 and 6 months. Conclusion: Margin involvement in conization specimens was a significant factor predicting residual/recurrent disease after LEEP. HPV test results at 3 and 6 months after treatment were comparable. Early 3-month follow-up testing after LEEP can offer timely information about residual/recurrent disease and alleviate patient anxiety early about treatment failure.

Multiple primary or secondary malignancies after anticancer therapy were recently reported to be increasing in frequency. The authors describe a case of metachronous metastatic pulmonary basaloid carcinoma to the central nervous system that was discovered after chemotherapy and radiation therapy for cervical uterine carcinoma. Two different types of cancer developed within some interval. There’s the possibility that a secondary pulmonary neoplasm developed after the chemotherapy and radiotherapy conducted as cervical cancer treatment.

Minimal Deviation Endometrioid Adenocarcinoma of the Uterine Cervix - A Case Report -
권계원,진수지,김희경,고은석,김규래,남계헌 대한병리학회 2008 Journal of Pathology and Translational Medicine Vol.42 No.4
We describe here a case of minimal deviation endometrioid adenocarcinoma (MDEA) of the uterine cervix that was initially suspected according to the abnormal cytologic findings in a 39-year-old woman. The Papanicolaou (pap) smear showed many neoplastic glandular cells in monolayered sheets, rosettes, and clusters with palisading and feathering borders. The tumor cells had oval, hyperchromatic nuclei, with chromatin clumping and small nucleoli. Histologic examination disclosed endometrial-type glands with a bland, isolated, mainly rounded appearance and these glands were widely scattered deep into the cervical stroma with only scant stromal reaction. An association of MDEA with tubo-endometrioid metaplasia or cervical endometriosis has been suggested by identifying the tubo-endometrioid glands in the vicinity of the MDEA.
