Background: This study aimed to determine the utility and a cut-off level of serum squamous cell carcinoma antigen (SCC-Ag) to predict lymph node metastasis in locally advanced cervical cancer cases. We also investigated the correlation between SCC-Ag level and lymph node status. Materials and Methods: From June 2009 to June 2014, 232 patients with cervical cancer stage IB2-IVA, who were treated at Ramathibodi Hospital, were recruited. Receiver operating characteristic (ROC) curves were used to identify the best cut-off point of SCC-Ag level to predict lymph node metastasis. Quantile regression was performed to evaluate the correlation between SCC-Ag levels and pelvic lymph node metastasis, paraaortic lymph node metastasis, and parametrial involvement as well as tumor size. Results: Pelvic lymph node metastasis and paraaortic lymph node metastasis were diagnosed in 46.6% and 20.1% of the patients, respectively. The median SCC-Ag level was 6 ng/mL (range, 0.5 to 464.6 ng/mL). The areas under ROC curves between SCC-Ag level and pelvic lymph node metastasis, paraaotic lymph node metastasis, parametrial involvements were low. SCC-Ag level was significantly correlated with paraaortic lymph node status (p=0.045) but not with pelvic lymph node status and parametrial involvement. SCC-Ag level was also related to the tumor diameter (p<0.05). Conclusions: SCC-Ag level is not a good predictor for pelvic and paraaortic lymph node metastasis. However, it is still beneficial to assess the tumor burden of squamous cell carcinoma of the cervix.

Introduction: Lymphoepithelioma-like carcinoma of the skin (LELCS) is a rare cutaneous tumor of low grade malignancy and microscopically resembles lymphoepitheliomatous malignancies in the nasopharynx, palatine tonsils, salivary glands and uterine cervix. LELCS presents as scarlet-colored firm nodules or plaques on the face, scalp, or shoulder of middle-aged to elderly individuals. Material and Methods: A 72 year-old female had complained a papule like lesion with intermittent pruritis on the left temple for 2 years. But the lesion was changed to scarlet-colored firm nodule with ulceration. The mass was diagnosed as LELCS on the biopsy. And to confirm that the mass is not metastatic lymphoepithelioma-like carcinoma from other sites or direct tumor extension from the nasopharynx, selective radiographic and laboratory tests were done carefully. Results: Wide excision was performed with general endotracheal anesthesia. The tumor is composed of island of large epithelial cells surrounded by as dense infiltrate of lymphocytes. Immunohistochemical staining with cytokeratin and epithelial membrane antigen(EMA), the tumor cells were positive reaction for stain. And Epstein-Barr virus genome was not detected by in situ hybridization. So, the tumor was confirmed as LELCS. Conclusion: LELCS was described by Swanson at 1988, but has not been reported in the field of plastic surgery of Korea. We report a case of primary LELCS that occurred in the left temple with clinical characteristics, histologic features and references.

Background: To study the clinical presentation of cervical carcinoma correlating with histopathological findings in a tertiary hospital situated in the southern part of India catering to rural and semi-urban populations Materials and Methods: 199 cases histopathologically diagnosed as cervical cancer over a period of one year were considered for the study. Clinical details of the patients were noted with the help of semi-structured proforma. The data was analysed by descriptive analysis using SPSS software. Results: Out of 199 patients, 109 had moderately differentiated squamous cell carcinoma, 51 poorly differentiated and 35 well differentiated. Adenocarcinomas numbered only four. 121 cases were in the age group of 40-59 years, 59 in 60-80 years and 19 in 20-39 years. All four cases of adenocarcinoma were seen between 40-59 years. 95 (47.7%) cases were in women who had 4 or more children, 120 presented with white discharge, 89 with bleeding per vagina and 68 had constitutional symptoms. Most of the patients with adenocarcinoma presented with bleeding per vagina. 151 was in stage IIIB, 29 in stage IIB, 14 in stage IVA and 5 in stage IB. Conclusions: Screening of cervical cancer should be emphasised in women with white discharge especially in rural areas for early detection of dysplastic cells and reduce mortality and morbidity in productive age. In addition health education has to be given to women regarding the awareness of hygiene, risk factors and symptoms of cervical cancer.

목적: 국소적으로 진행된 자궁경부암의 치료는 방사선 단독요법이 주 치료였으나 근래에는 좀 더 완치율을 높이기위해 약물치료와 병행하여 방사선치료가 시행되고 있다. 저자들은 45명의 방사선 단독요법과 77명의 항암화학과 방사선의 병용요법의 치료성적을 후향적으로 분석하였다. 방법: 1985년 1월부터 1991년 12원까지 한양대학병원 치료방사선과에서 외부방사선 및 강내방사선치료를 받은 환자 122명을 대상으로 후향적으로 분석하였다. 34명은 ICR 1회, 77명은 ICR 2회, 11명은 고선량 강내근접 방사선치료를 받았다. 연령분포는 29세부터 81세였고, 중앙연령은 58세였다. 추적기간은 5개월에서 117개월(5명이 34개원 미만)로 중앙값은 60개월이었다. 조직병리상 111명이 squamous cell ca, 5명이 large cell ca, 4명이 adenoca, 2명이 adenosquamous cell ca였다. FIGO 병기로 IB $6명(4.9\%),$ IIA 11명$(9.0\%),$ IIB 37명$(30.3\%),$ IIIA 3명$(2.5\%),$ IIIB 63명$(51.6\%),$ IVA 2명$(1.6\%)$이었다. 항암화학요법을 병용한 환자 77명중 36명은 VBP, 39명은 cispiatin 과 5-FU, 2명은 5-FU 제제로 치료받았다. 결과: 외부방사선조사량 3900 cGy에서 5500 cGy를 받은환자에서 61명$(50\%)$이 육안적으로 완전관해를보였다. 5년 및 9년 생존율은 전체환자에서 각각 $57.8\%,\;53.9\%$였고 방사선 단독요법의 5년 생존율이 $63.1\%,$ 방사선과 항암화학복합요법의 5년 생존율은 $55.9\%$였다. 항암제 VBP(vinblastin, bleomycin, cisplatinum)로 치료받은 환자에서 5년 생존율이 $63\%$이고 cisplatin으로 치료받은 환자는 $50\%$이나 통계적인 유의성은 없었다. ICR 회수에따른 5년 생존율은 1회 ICR에서 $36.5\%,$ 2회 ICR에서 $67\%$였다. 방사선단독요법으로 치료받은 환자중 A point에 8000 cGy이상 받은 환자에서 5년 생존율이 $91.4\%$이었고 8000 cGy 미만 환자는 $27.2\%$로 통계적으로 유의한 생존율의 향상을 보였다(p<0.01). 항암화학요법으로 치료받은 환자는 A point의 dose에 따른 생존율의 차이를 보dl지 않았으며(<8000 cGy $55.6\%\;vs\;<=8000\;cGy\;55.7\%)$ 1회의 ICR 과 2회의 ICR의 5년 생존율에도 큰 차이가 없었다$(50\%\;vs\;56.8\%).$ 병변크기가 3cm 이상인 환자에서 방사선 단독치료법과 항암화학치료법과의 5년 생존율의 차이가 없었다$(48.9\%\;vs\;48.7\%).$ 초기 병변에서 항암화학치료를 받지않은 군과 받은 관의 5년 생존율은 $60\%$와 $78\%$이나 숫자가 매우적어 의미가 없었고 진행된병기에서 5년 생존율은 방사선 단독군이 조금 좋았으나 통계적 유의성은 없었다$(62.6\%\;vs\;53.6\%)$ (p>0.05). 결론: 본 연구결과 방사선치료에 항암화학 병용은 생존율향상을 시키지 못하였다. 방사선단 독요법이 국소적으로 진행된 환자에 치료방법이며 A point에 8000 cGy이상 받은환자에서 생존율이 높았고 항암화학 병용요법 치료에서는 A point의 방사선양이 생존율에 영향을 미치지 않았다.

Objectives: To evaluate the clinicopathologic correlation and prognostic value of HPV18 DNA viral load in patients with early-stage cervical neuroendocrine carcinoma (NECA). Methods: Formalin-fixed, paraffin-embedded tissue of cervical NECA patients with known HPV18 infection and clinicopathologic data including follow-up results were collected. The HPV18 DNA load was assessed with quantitative PCR targeting the HPV18 E6E7 region. Results: Twenty-one patients with early-stage (IB-IIA) cervical NECA were identified. HPV18 DNA viral load ranged from 0.83 to 55,174 copies/cell (median 5.90). Disease progression, observed in 10 cases (48%), was not significantly associated with any clinicopathologic variables. However, the group of patients with progressive disease tended to have a higher rate of pelvic lymph node metastasis (50% versus 9%, p=0.063) and a lower median value of HPV18 DNA viral load (4.37 versus 8.17 copies/cell, p=0.198) compared to the non-recurrent group. When stratified by a cut-off viral load value of 5.00 copies/cell, the group of patients with viral load ${\leq}5.00$ copies/cell had a significantly shorter disease-free survival than the group with viral load >5.00 copies/cell (p=0.028). The group with a lower viral load also tended to have a higher rate of disease progression (75% versus 31%, p=0.080). No significant difference in the other clinicopathologic variables between the lower and higher viral load groups was identified. Conclusion: HPV18 DNA viral load may have a prognostic value in patients with early-stage NECA of the cervix. A low viral load may be predictive of shortened disease-free survival in these patients.

It was reported that the main cause of intraepithelial neoplasm and squamous cell carcinoma of the uterine cervix is human papilloma virus infection, and that the expression of p16 is increased in cells infected by human papilloma virus. We performed an immunocytochemical staining for protein p16 in 17 cases of cervocovaginal smears initially diagnosed as atypical squamous cells of undetermined significance, to know whether the staining could help the differentiation of neoplastic cells from reactive atypical cells. Of 17 smears, 6 were diagnosed finally as high grade intraepithelial neoplasm or invasive squamous cell carcinoma by follow-up biopsy and smear, and 5 of the 6 were positive for p16. Three were diagnosed as koilocytosis, and one of them was weakly positive for p16. Eight were diagnosed as reactive atypical cells, and all of them were negative for p16. We thought that immunocytochemical staining of p16 in cervocovaginal smears could help the differentiation of neoplastic cells from reactive atypical cells.

목적 : 방사선치료 중에 혈중 Squamous Cell Carcinoma Antigen (SCC) 값의 변화를 관찰하여 치료에 대한 반응을 감시할 수 있는 가능성을 알아보고 특히 치료중 원격전이 등으로 인한 치료실패가 발생할 경우에 조기에 발견할 수 있는지 알아보기 위해서 본 연구를 시행하였다. 대상 및 방법 : 1998년 12월부터 1999년 8월까지 단국대학병원 치료방사선과에서 원발성 자궁경부암으로 근치적 방사선치료를 시행 받은 환자 중 13례를 대상으로 하였고 치료전 및 외부조사 방사선치료 중 매주 1회씩, 그리고 치료 후에 혈중 SCC 치를 측정, 분석하였다. 결과 : 13례 중 9례에서는 외부조사 방사선치료 종료 후에 시행한 검사상 원격전이의 소견이 없어서 자궁강내 근접방사선치료를 시행할 수 있었다. 이들 9례 중 7례는 방사선치료 전에 혈중 SCC 치가 상승되어 있었다. 이 7례중 6례에서 치료 후 완전 관해의 소견을 보였는데 그중 5례에서는 혈중 SCC 치가 정상화되었다. 부분관해를 보인 1례에서는 혈중 SCC 치가 치료전보다 낮아졌으나 정상범위보다는 높았다. 13례 중 나머지 4례에서는 외부조사 방사선치료 종료시점에 원격전이가 확인되어서 자궁강내 근접방사선치료를 시행하지 못하였다. 이 중 3레는 방사선치료 전에 혈중 SCC 치가 상승되어 있었는데 외부조사 방사선치료 종료 직후 시행한 흉부단순촬영 사진상 원격전이의 소견이 나타났음에도 불구하고 이 때의 혈중 SCC 치는 감소하였다. 치료 전에 혈중 SCC가 상승되어 있었던 10례 중 7례에서 9 Gy 치료 후에 혈중 SCC 값이 더욱 증가하였으며 통계적으로 유의한 증가였다. 18 Gy 시행한 후의 값은 9 Gy 시행한 경우에 비해서는 3례에서 증가하였고 7예에서 감소하였으며 치료 전에 비해서는 4례에서 증가하였고 6례에서 감소하였다. 18 Gy 이후에는 방사선량의 증가에 따라서 계속적으로 혈중 SCC 치가 감소하여 종양이 완전 관해에 이르면 정상범위에 도달하였다. 결론 : 방사선치료 중에 혈중 SCC 치는 9 Gy까지는 치료 전에 비해서 일시적으로 증가하고 18 Gy에서는 치료전의 값과 비슷해지며 그 후에는 빠르게 감소해서 종양이 완전 관해에 이르면 정상치에 도달하였다. 외부조사 방사선치료 종료 후 흉부단순촬영 사진상 폐 전이의 소견을 보인 경우들도 혈중 SCC 치는 주로 자궁경부의 주종양의 관해도에 따라 감소하여 주종양의 완전관해시 정상화되었고 폐 전이의 발현에도 불구하고 증가하지 않았다.

Objectives: The purposes of this study were to determine the prevalence and predictive value to detect significant neoplasia and invasive lesions, and to evaluate the correlation between clinical and histopathology of women with squamous cell carcinoma (SCCA) on Siriraj liquid-based cervical cytology (Siriraj-LBC). Methods: The computerized database of women who underwent Siriraj-LBC at Siriraj Hospital, Mahidol University from January 2007 to December 2010 were retrieved. The hospital records of women with SCCA cytology were reviewed. Results: The prevalence of SCCA cytology was 0.07%. A total of 86 women, mean age was 58.1 years. Sixty-one women (70.9%) were post-menopausal. Overall significant pathology and invasive gynecologic cancer were detected in 84 women (97.7%) and 71 women (82.5%), respectively. The positive predictive values for detection of significant neoplasia and invasive lesion were 97.7% and 82.6%, respectively. The cervical cancer was diagnosed in 69 women and among these 58 women were SCCA. Thirteen women (15.1%) had cervical intraepithelial neoplasia (CIN) 3 and two women (2.3%) had cervicitis. The sensitivity and specificity of colposcopy for cervical cancer detection in SCCA cytology were 83.3% and 75%, respectively. Median follow up period was 17.6 months and 64 patients were alive without cytologic abnormality. Conclusions: The final histopathology of SCCA cytology in our populations demonstrated a wide variety, from cervicitis to invasive cancer and the most common diagnosis was invasive cervical cancer. Colposcopy with biopsy and/or endocervical curettage and loop electrosurgical excision procedure should be undertaken to achieve histologic diagnosis.

Paclitaxel is one of the best anticancer agents that has been isolated from plants, but its major disadvantage is its dose-limiting toxicity. In this study, we obtained evidence that the active mutant IPP5 ($8-60hIPP5^m$), the latest member of the inhibitory molecules for protein phosphatase 1, sensitizes human cervix carcinoma cells HeLa more efficiently to the therapeutic effects of paclitaxel. The combination of $8-60hIPP5^m$ with paclitaxel augmented anticancer effects as compared to paclitaxel alone as evidenced by reduced DNA synthesis and increased cytotoxicity in HeLa cells. Furthermore, our results revealed that $8-60hIPP5^m$ enhances paclitaxel-induced G2/M arrest and apoptosis, and augments paclitaxel-induced activation of caspases and release of cytochrome C. Evaluation of signaling pathways indicated that this synergism was in part related to downregulation of NF-${\kappa}B$ activation and serine/threonine kinase Akt pathways. We noted that $8-60hIPP5^m$ downregulated the paclitaxel-induced NF-${\kappa}B$ activation, $I{\kappa}B{\alpha}$ degradation, PI3-K activity and phosphorylation of the serine/threonine kinase Akt, a survival signal which in many instances is regulated by NF-${\kappa}B$. Together, our observations indicate that paclitaxel in combination with $8-60hIPP5^m$ may provide a therapeutic advantage for the treatment of human cervical carcinoma.
