  • To determine the correlation between mast cells(MCs) and neoangiogenesis in the growth and progression of cervical cancer, we investigated mast cell density(MCD), microvessel density(MVD) and the expression of vascular epithelial growth factor(VEGF) in cervical intraepithelial neoplasia and invasive suqamous cell carcinoma of the uterine cervix. Forty-five cervical intraepithelial neoplasia(CIN I, II and III), 15 microinvasive carcinomas, 15 invasive squamous cell carcinomas and 20 normal cervical epithelia were included in this study. MCs were stained with anti-c-Kit antibody and alcian blue, microvessels with anti-factor VIII antibody and VEGF with anti-VEGF antibody. The adjacent fields of both normal and neoplastic epithelium were used for counting MCs and microvessels. Computerized image analysis was used to evaluate MCD and MVD. MCD and MVD were the mean numbers per $1mm^2$ counted in 5-10 high and low power fields respectively. In both c-Kit and alcian blue stained sections, MCD progressively increased along the continuum from CIN I to invasive squamous cell carcinoma(p<0.001). MVD increased significantly with cervical neoplasia progression, from CIN to invasive squamous cell carcinoma (p<0.001). In double c-Kit and Factor VIII-stained sections, MCs were mainly present in the areas adjacent to newly formed blood vessels. However, there were no significant differences in MCD and MVD between normal epithelum and CIN I. A strong correlation was also observed between MCD and MVD. In double VEGF and alcian blue-stained sections, VEGF was expressed in only MCs. Strong VEGF-positive MCs were particularly abundant around the tumorous region. Our results suggest that MCs may upregulate neoangiogenesis by VGEF secretion in the development and progression of cervical neoplasia.

  • The prevalence of Epstein-Barr virus(EBV) in the uterine cervix was investigated to define the possible etiologic role in cervical carcinogenesis. The viral genotyping and LMP-1 30bp deletion were also stooled. The materials included 169 uterine cervical swabs(152 within normal limits, 12 atypical squamous cells of uncertain significance, 3 low grade intraepithelial lesions, and 2 high grade squamous intraepithelial lesion) and 104 uterine cervical tissues obtained from hysterectomy specimens(32 carcinoma in situ, 9 microinvasive squamous cell carcinomas, 37 invasive squamous cell carcinomas, 7 adenocarcinomas, 7 adenosquamous carcinomas, and 12 cervicitis). EBV detected by PCR for EBNA-1 was positive in 52(56.5%) of 92 invasive and noninvasive cervical carcinomas, and 80(48.8%) of 164 inflammatory or normal cervices. The viruses detected in carcinomas were all type A, and LMP-1 30bp deletion form was more frequent in premalignant and malignant cervical lesions than in nonneoplastic cervices. From the above results, it may be concluded that EBV is one of common viruses detected in uterine cervix of Korean women, and type A virus and LMP-1 30bp deletion form may have a role in cervical carcinogenesis.

  • This is a retrospective cohort analysis of 58 patients who treated with postoperative radiation therapy following radical hysterectomy and bilateral pelvic adenectomy for early stage carcinoma of uterine cervix between January 1988 and December 1990 at department of radiation oncology, Keimyoung University Hospital. Sixteen percent of patients (9/58) had chemotherapy. Most patients were FIGO I b (47 patients), and FIGO I a and II a were one and ten patients, respectively. The median follow-up periods were 48.5 months. The indications for radiation therapy included pelvic lymph node metastasis, large tumor size, deep stromal invasion, lymphovascular invasion, positive surgical margin, endometrial invasion and parametrial invasion. Eighty five percent of the patients had more than one risk factor. The actuarial overall five year survival rate (5 YSR) and five year disease free survival rate (5 YDFSR) were $89.5\%,\;and\;87.8\%,$ respectively. Their overall recurrence rate was $12.1\%,$(758). Distant metastasis was the most common cause of treatment failure $(71.4\%:5/7).$ The univariate analysis of prognostic factors affecting to five year survival rate disclosed pelvic lymph node status (negative: $95.5\%,\;positive:69.2\%,$ p=0.006) and hemoglobin level $(\le11 :75\%,>11g/dl:93.3\%,p=0.05)$ as significant factor. The age status was marginally significant $(\le40:96.0\%,\;>\;40:84.3\%p=0.15).$ Multivariate analysis clarified three independent prognostic factors: pelvic lymph node metastasis (p=p.006), hemoglobin level (p=0.015) and age (p=0.035). Multivariate analysis of prognostic factor affecting to five year disease free survival rate disclosed pelvic lymph node status (p=0.0078) and status of surgical margin (p=0.008). Complications relating to radiotherapy were $10.3\%,(6/58).$ There were no severe major complication requiring surgical intervention or a long hospital stay. It is our opinion that the benefit of postoperative pelvic radiotherapy may be gained in such a high risk patient population with acceptible morbidity.

  • Background : Cervicovaginal cytology is a screening test of uterine cervical cancer. The sensitivity of cervicovaginal cytology is less than 50%, but studies of cytologic/histologic correlation are limited. We analyzed the diagnostic accuracy of cervicovaginal cytology in the detection of the squamous epithelial lesions of the uterine cervix and investigate the cause of diagnostic discordance. Materials and Methods : We collected a total of 481 sets of cervicovaginal cytology and biopsies over 5 years. The cytologic diagnoses were categorized based on The Bethesda System and the histologic diagnoses were classified as negative, flat condyloma, cervical intraepithelial neoplasia (CIN) I, CIN II, CIN III, or squamous cell carcinoma. Cytohistologic discrepancies were reviewed. Results: The concordance rate between the cytological and the histological diagnosis was 79.0%. The sensitivity and specificity of cervicovaginal cytology were 80.6% and 92.6%, respectively. Its positive predictive value and negative predictive value were 93.7% and 77.7%, respectively. The false negative rate was 19.4%. Among 54 false negative cytology cases, they were confirmed by histology as 50 flat condylomas, 2 CIN I, 1 CIN III, and 1 squamous cell carcinoma. The causes of false negative cytology were sampling errors in 75.6% and interpretation errors in 24.4%. The false positive rate was 7.4%. Among 15 false positive cytology cases, they were confirmed by histology as 12 atypical squamous cells of undetermined significance (ASCUS) and 3 low grade squamous intraepithelial lesions (LSIL). The cause of error was interpretation error in all cases. The overall diagnostic accuracy of cervicovaginal cytology was 85.7%. Conclusions : Cervicovaginal cytology shows high overall diagnostic accuracy and is a useful primary screen of uterine cervical cancer.

  • 목적 : 자궁경부암의 치료후의 재발이나 병소의 지속을 발견하기 위한 종양표지자로서의 squamous cell carcinoma antigen(SCC) 와 carcinoembryonic antigen(CEA) 의 의의를 확인하고 향후의 치료시에 참고하고자 한다. 대상 및 방법 : 1995년 10월부터 1998년 8월까지 단국대학병원 치료방사선과에서 원발성 자궁경부암으로 근치적 방사선치료를 시행 받은 환자 중 22례를 대상으로 하였고 방사선치료전에 MRI 나 초음파를 시행하여 종양의 체적을 구하였으며 방사선치료 전에 SCC 와 CEA를 측정하였고 치료 후에도 주기적으로 SCC 와 CEA를 측정 하여 분석 하였다 결과 : 방사선 치료전에 측정한 SCC 치는 전체 22례 중 68.2$\%$ 에서 상승되어 있었으며, CEA 치는 측정이 이루어진 21례 중 19.0$\%$에서 상승되어 있었다. 종괴의 부피와 치료전의 SCC 치의 관련성은 극단적으로 벗어난 1례를 제외하면 상관계수가 0.59382 로 상당히 컸다. 종괴의 부피증가에 따른 CEA 치의 증가경향은 없었다. 치료후의 SCC 치는 9.1$\%$ 에서 CEA 치는 측정이 이루어진 21례 중 4.8$\%$ 에서 상승되어 있었다. 방사선치료 전에SCC 치가 상승되어 있었던 15례 중 14례에서 완전관해의 소견을 보였으며 그 14례 중 SCC 치가 정상 범위로 낮아진 경우가 13례(92.9$\%$) 였다. SCC 치가 치료 전에 상승되어 있다가 치료 후에 정상화 된 13례 중 5례에서 SCC 치의 정상 범위 이상의 재상승이 나타났는데 그 중 4례는 국소실패(3례) 혹은 국소 및 주변 림프절 실패(1례) 였고 나머지 1례는 임상적으로 무병상태(NED) 이다. 따라서 재발과 관련된 SCC 치 상승의 민감도는 100$\%$, 특이도는 93.8$\%$, 양성예측도는 85.7$\%$ 였다. SCC 의 재상승이 있은 후 임상적 재발을 발견할 때까지의 시간차이(lead time) 는 평균 1.2개월이었다. CEA 는 치료전 높았던 4례 모두에서 치료 후 완전 관해시에 정상화 되었고 이들 중 재발한 경우는 없었다. 결론 : 본 연구에서 SCC 와 CEA 는 치료전의 값이 상승되어 있었던 경우는 치료에 대한 반응과 재발을monitor 하는데 좋은 종양표지자로 나타났다. 그러나 치료전 SCC 치가 민감도가 높은데 비해 CEA 치는 민감도가 낮으며 CEA 와 SCC 를 모두 측정한 경우가 SCC 만 측정한 경우에 비해 예후의 관찰에 유리한 점이 없었다.

  • Background: The aim of this study was to evaluate the prognosis of patients with stage IA-IIB cervical carcinoma and to investigate a possible correlation of histology with prognosis. Materials and Methods: Two hundred fifty one patients with adenocarcinoma and squamous cell carcinoma (SCC) histology for FIGO (International Federation of Gynecology and Obstetrics) stage IA-IIB uterine cervical carcinomas at the Radiation Oncology Clinic of GH Okmeydan Training and Research Hospital between January 1996 and December 2006 were selected, analyzed retrospectively and evaluated in terms of general characteristics and survival. Disease-free survival (DFS) and overall survival (OS) was calculated using the Kaplan-Meier method and differences were compared with the log-rank test. Multivariate analysis using a Cox-proportional hazards model was used to adjust for prognostic factors and to estimate hazard ratio (HR) with 95% confidence interval (CI). Results: There was no differences between the two tumour types in age, stage, pelvic nodal metastasis, parametrial invasion, surgical margin status, DSI, LVSI, maximal tumor diameter, grade, and treatment modalities. 5-year OS and DFS were 73% and 77%, versus 64% and 69%, for SCC and adenocarcinoma, respectively (p> 0.05). Multivariate analysis revealed independent prognostic factors including pelvic nodal metastasis and resection margin status for OS (p=0.008, p=0.002, respectively). Conclusions: Prognosis of FIGO stage IA-IIB cervical cancer patients was found to be the same for those with adenocarcinoma and SCC.

  • 47 out of 56 cases of intact uterine cervix cancer treated by radiation at the Hanyang University Hospital were followed 18 months or more after treatment. (7 patients died before 18 months, 2 cases lost to follow-up). Age distribution reveal 5 cases in 30's, 18 cases in 40's, 17 cases in 50's, 7 cases in 60's. Histologically, all cases were squamous cell type except one case of adenocarcinoma. 1. 45 cases were treated by combined external Co-60 irradiation and intracavitary irradiation by Cs-137 small sources. 1 case was treated by external irradiation only, and 1 case by intracavitary only. 2. Rectal injuries were observed in 13 cased (27.6%), 4 cases in Grade 1, 8 cased in Grade 2 and 1 cases in Grade 3 which needed surgical management. 3. Average intervals of rectal injury following treatment was 9.2 months varying from 5 to 15 months. 4. Relation between rectal injury and point A dose reveal 6 cases between 7000-7999 rad and 6 cases between 8000-8999 rad and 1 case above 9000 rad. Even though there is no direct relation between point A dose and rectal injury, it is expected that rectal injury increases as point A dose increase. 5. In the normal condition, rectal injury can't be attributed to one major cause. Radiation dose, small source distribution, general condition of patients, local anatomy of the individual patient, history of PID and previous surgery, all play complex roles.
