Purpose : Hysterectomy without lymph node dissection was considered an inadequate treatment method for invasive uterine cervix cancer. Usually the procedure was performed inadvertently on patients who were thought to have benign or premalignant conditions preoperatively. We analysed radiotherapy results of such patients to evaluate survival rates, failure patterns and prognostic factors according to various conditions. Materials and Methods : Sixty one patients undergoing hysterectomy in the presence of invasive cervical carcinoma were reviewed retrospectively. Preoperative diagnosis were carcinoma in situ (38 cases), severe dysplasia (2), myoma (6), uterine bleeding (4), uterine prolapse (2). and early invasive cervix cancer (10) (One patient had myoma and carcinoma in situ coincidently). Patients received postoperative megavoltage radiotherapy from August 1985 to December 1993, and minimum follow-up period was 24 months. Eight patients received ICR only, 6 patients ICR and external radiation, and 47 patients received external radiation therapy only. Results : Overall 5-year survival rate and relapse-free survival rate werer $83.8\%$, $86.9\%$ respectively. For patients with retrospective stage IA, IB, IIB (gross residual after surgery), and vaginal cuff recurrence were $90.9\%$, $88.8\%$, $38.4\%$, and $100\%$ respectively There were 8 cases of treatment failure, most of them (5/8) were in patients with gross residual disease, other patients were full thickness involvement of cervix wall (2/8) except one. Patients with early vaginal cuff recurrence and microinvasive cervical cancer (stage IA) had no treatment related failure Prognostic factors affecting survival by univariate analysis were status of residual disease, tumor histology and retrospective stage. Conclusion : Adjuvant radiotherapy appeared to be effective treatment method for patients with presumed stage IA, IB and early local recurrent disease after inadvertent hysterectomy Survivals for patients with gross disease remained after inappropriate hysterectomy was poor, So, early cancer detection and Proper management with precise pretreatment s1aging is necessary to avoid inadherent hysterectomy especially in the cases of gross residual disease.

Purpose: The relationship between treatment outcomes, alteration of the expression of biological markers, and tumor volume response during radiotherapy (RT) in patients with uterine cervical cancer was analyzed. Materials and Methods: Twenty patients with cervical squamous cell carcinoma received definitive RT with (n = 17) or without (n = 3) concurrent chemotherapy. Tumor volumes were measured by three serial magnetic resonance imaging scans at pre-, mid-, and post-RT. Two serial punch biopsies were performed at pre- and mid-RT, and immunohistochemical staining for cyclooxygenase (COX)-2 and epidermal growth factor receptor was performed. The median follow-up duration was 60 months. Results: The median tumor volume response at mid-RT (V2R) was 0.396 (range, 0.136 to 0.983). At mid-RT, an interval increase in the distribution of immunoreactivity for COX-2 was observed in 8 patients, and 6 of them showed poor mid-RT tumor volume response ($V2R{\geq}0.4$). Four (20%) patients experienced disease progression after 10 to 12 months (median, 11 months). All 4 patients had poor mid-RT tumor volume response (p = 0.0867) and 3 of them had an interval increase in COX-2 expression. Overall survival (OS) and progression-free survival (PFS) decreased in patients with $V2R{\geq}0.4$ (p = 0.0291 for both). An interval increase in COX-2 expression at mid-RT was also associated with a decreased survival (p = 0.1878 and 0.1845 for OS and PFS, respectively). Conclusion: Poor tumor volume response and an interval increase in COX-2 expression at mid-RT decreased survival outcomes in patients with uterine cervical cancer.

Background: This study aimed to develop a prognostic model in patients with early-stage cervical squamous cell carcinoma based on clinicopathological features, including invasive margin characteristics. Materials and Methods: Clinicopathological features and outcomes of 190 patients with FIGO stage IB-IIA cervical squamous cell carcinoma treated by surgery were collected and analyzed for factors associated with tumor recurrence. In addition to well-recognized pathological risk factors, the pathological characteristics of invasive margin (type of invasive pattern and degree of stromal desmoplasia and peritumoral inflammatory reaction) were also included in the analysis. Multiple scoring models were made by matching different clinicopathological variables and/or different weighting of the score for each variable. The model with the best performance in the prediction of recurrence and decreased survival was selected. Results: The model with the best performance was composed of a combined score of invasive pattern, lymphovascular space invasion (LVSI), and degree of inflammatory reaction and stromal desmoplasia (total score =10). Compared to those with score ${\leq}8$, the patients with score 9-10 had a significantly higher recurrence rate in the overall group (p<0.001) and the subgroup without adjuvant therapy (p<0.001), while the significance was marginal in the subgroup with adjuvant therapy (p=0.069). In addition, the patients with score 9-10 had a higher rate of tumor recurrence at distant sites (p=0.007). The disease-free survival was significantly lower in the patients with score 9-10 than those with score ${\leq}8$ among the overall patients (p<0.001), in the subgroup without adjuvant therapy (p<0.001), and the subgroup with adjuvant therapy (p=0.047). Conclusions: In this study, a prognostic model based on a combination of pathological characteristics of invasive margin and LVSI proved to be predictive of tumor recurrence and decreased disease-free survival in patients with early-stage cervical squamous cell carcinoma.

Background: In Morocco, the epidemiological profile of cervical cancer is not well established. The focus of the present study was both epidemiological and pathological characteristics. Methods: For all cases of cervical cancer treated between 2003 and 2007 in the National Institute of Oncology and the Oncology Department of the IbnRochd hospital (Casablanca), 900 cases were randomly selected. Results: The mean age was $52.1{\pm}11.8$ years. The most (90.5%) represented histological type was squamous cell carcinoma. For more than 57.0% cases the mean distance between patient's origin and center of treatment was greater than 100km. According to the FIGO classification, only 17.2% of patients were identified as being in early stages (0 and I). For 72.2% patients the follow-up did not exceed 2 years. At 1 year of following-up 55.8% of patients were alive and 43.4% were lost to following-up. Conclusion: Our study addressed the issue of the burden of cervical cancer in Morocco. The result provides a basis for decision-makers for the development of strategic measures to implement the fight against cervical cancer in Morocco.

Euonymus alatus(Thunb.) Sieb has been used for cancer theraphy such as Liver cancer, esophagus cancer, stomach cancer, and uterine cancer in folk. Eupolyphaga simemsis(ES) extracted from Euonymus alatus(Thunb.) Sieb increases HDL-C/TC ratio and LCAT activity. TGF-${\beta}$ and Insulin has been Knoen as factors to induce the supression of proliferation of Hep3B, Human hepatoblastoma cell. Plasma HDL3-C involved in carbohydrate methabolism in the liver was maintained in low level by Euonymus alatus(Thunb.) Sieb. The low level of plasma HDL3-C suppresses the transition from normal liver to Fat liver. Finally, this resuly in suppression of cancer in liver. In this study, Euonymus alatus(Thunb.) Sieb showed higher cell toxicity in hepatoblastoma cell(Hep3B) compared to the uterine cancer cell(HeLa). This means Euonymus alatus(Thunb.) Sieb seems not to affect in the all kinds of cancer. In future, we will study whether Euonymus alatus(Thunb.) Sleb have an effect on the liver cancer induced by virus and hepatocellular carcinoma. Also, the mechanims of suppression of cell proliferation in HCC need to investigated.

Background: To investigate the expression of CD44v3 and vascular endothelial growth factor-C (VEGF-C) and their relationship with lymph node metastasis in squamous cell carcinomas (SCC) of the uterine cervix. Materials and Methods: Expression of CD44v3 and VEGF-C was analyzed in 109 cases of cervical SCC by immunohistochemistry (IHC). The relationship was analyzed between expression and the patient age, histological differentiation, formation of tumor emboli in lymphoid vessels, lymph node metastasis, FIGO staging, and TNM classification. Results: Expression rates for both CD44v3 and VEGF-C were 43.1% in cervical SCC. The cells with positive immunohistochemical staining of CD44v3 were distributed mainly around the keratin pearls in well differentiated carcinomas, but distributed diffusely in the moderately and poorly differentiated lesions. VEGF-C was found stained positively in most of the tumor cells. There were differences in expression between normal epithelium and atypical hyperplasia as well as carcinoma. Both CD44v3 and VEGF-C were found to be associated positively with lymph node metastasis and TNM classification (both p=0.000). Neither CD44v3 nor VEGF-C was found to be associated with patient age, histological differentiation, formation of tumor emboli in lymphoid vessels and FIGO staging. CD44v3 was found to be associated with VEGF-C positively (p=0.000). Conclusions: Abnormal expression of CD44v3 and VEGF-C is associated closely with the lymph node metastasis in cervical SCC, and these agents may cooperate in carcinogenesis and development of metastatic lesions.

We have investigated the cervicovaginal smears in order to define the cytologic features of uterine adenocarcinomas. Total 22 cases were reviewed(12 cases from the Sanggye Paik hospital, Inje university and 10 cases from the Korea Cancer Center Hospital) from January 1992 to December 1997. Five cases were endometrial adenocarcinomas and the remaining 17 cases were cervical adenocarcinomas. Seventeen cases of cervical adenocarcinomas were divided into endometrioid(6 cases), endocervical(7 cases), mixed endometrioid and endocervical(1 case), papillary (2 cases), and adenosquamous(1 case) carcinomas. The background of endocervical adenocarcinoma was hemorrhagic or inflammatory. The tumor diathesis was less prominent than that of the squamous cell carcinoma. The prominent features of the endocervical type adenocarcinomas were large and loose clusters, large intracytoplasmic vacuoles, and prominent overlapping and peripheral palisading of nuclei. In contrast, the endometrioid adenocarcinomas showed small and compact clusters, and small intracytoplasmic vacuoles. The detection rate of endometrial adenocarcinoma was lower than that of the endocervical adenocarcinoma.

The recently proposed Bethesda system for cervical/vaginal cytology has made a standardization related to "atypia". In cellular change due to inflammation or repair, the word "benign cellular change" has been suggested as a substitute for atypia. Terminology related to atypia cells may become standardized, but the cytologic criteria has not been well defined yet Among 8113 cases screened, we evaluated 182 cases as atypia squamous cells undetermined significance (ASCUS) by the Bethesda system (TBS): 52 cases of ASCUS were cytologically diagnosed and 33 cases were histologically verified. ASCUS was diagnosed based on nuclear enlargement and nonclassical signs of condyloma. The results are as follows; Six cases (16.6%) turned out to have benign cellular change. Twenty five cases (69.1%) demonstrated squamous intraepthelial lesion, condyloma was 2 cases (6.0%) and mild dysplasia was not revealed. Moderate and severe dysplasia were 1 case (3.0%) and 16 cases (48.4%), squamous cell carcinoma and adenocarcinoma were 4 (12.1%) and 1 cases (3.0%), respectively. Our data suggested that patients with ASCUS are highly recommended to be examined colposcopic biosy to cornfim.

Purpose : To assess the efficacy of high dose rate - intracavitary radio-therapy (HDR-ICR) in the radiotherapy of FIGO stage IB squamous cell carcinoma of uterine cervix and to determine the optimum dose combination scheme of external radiotherapy and ICR to achieve acceptable local control without severe complication. Materials and Methods : One hundred and sixty two patients with FIGO stage Ib squamous cell carcinoma of uterine cervix who received definitive radiotherapy between May 1979 and December 1990 were retrospectively analyzed. All the patients received external radiotherapy combined with HDR-ICR. External dose of 40-46 Gy in 4.5-5 weeks was given to whole pelvis(median 45 Gy) and ICR dose of 30-39 Gy in 10-13 times was given to the point A. Midline shielding was done after 20-45 Gy of external radiotherapy(median 40 Gy) Summation of external dose Plus ICR dose to the point A range were 64.20-95.00 Gy. and mean was 83.94 Gy. We analyzed the local control rate, survival rate, and late complication rate. Rusults : Initial complete response rate was $99.4\%$ for all patients. Overall 5-year survival rate was $91.1\%$ and 5-year disease free survival rate was $90.9\%$. Local failure rate was $4.9\%$ and distant failure rate was $4.3\%$. Tumor size was the only significant prognostic factor. When tumor size greater than 3cm, 5-rear survival rate was $92.6\%$ and less than 3cm, that was $79.6\%$. Late complication rate was $23.5\%$ with $18.5\%$ of rectal complication and $4.9\%$ of bladder complication. Mean rectal dose summation of external midline dose plus ICR rectal point dose was lower in the patients without rectal complication(74.88 Gr) than those with rectal complication (78.87 Gy). Complication rate was increased with low rate of improvement of survival rate when summation of external midline dose plus point A or point R dose by ICR was greater than 70-75 Gy. Conclusion : The definitive radiation therapy using high dose rate ICR in FIGO stage IB uterine cervical cancer is effective treatment modality with good local control and survival rate without severe complication.

Purpose : The authors conducted a retrospective analysis of patients with the carcinoma of uterine cervix treated with curative radiation therapy to evaluate the prognostic factors that would affect the results of the therapy and to get the critical ideas in determining more aggressive treatment schedule. Methods and Materials : From January 1987 to December 1988. Four hundreds and sixty patients with uterine cervical carcinomas treated with radiotherapy at KCCH were registered to this retrospective study. One hundred and three patients were treated with external radiation therapy alone, and 357 patients were treated with external radiation followed by low dose rate intracavitary radiation therapy. The follow-up rate was 88% and median follow-up duration was 48 months. Results : The overall 5 year survival rate of the patients was 67.7%, and when classified by FIGO stages, 5 year survival rates were 81.2%, 76.3%, 73.1%, 50%. 52.3%, 11.5% for stages Ib, IIa, IIb, IIIa, IVa respectively. Tumor size(p=0.0002), endocervical growth pattern(p=0.003), lymph node invasion(p=0.0001), mean hemoglobin level(p=0.0001), and pathologic cell type(p=0.0001) were significant prognostic factors and decrease in survival for young age patient group was marginally important (p=0.03). Conclusion : Significant prognostic factors in the radiation therapy of the uterine cervical carcinoma were tumor size, growth pattern of tumor, lymph node invasion, pathologic cell type, hemoglobin level of patients during treatment and lower survival rate in young age group was obvious, too. Patients with large size tumor(${\geq)$4cm), especially combined with endocervical growth patterns or advanced stages(III or more) need more aggressive treatment to improve the outcome of treatment. And positive feature of lymph node invasion affected the result of therapy, so improvement in the diagnostic and therapeutic trial is essential.
