  • Objective: To examine the association between tumor grade and survival for women with squamous cervical cancer. Methods: This retrospective observational study utilized the Surveillance, Epidemiology, and End Result program data between 1983 and 2013 to examine women with squamous cervical cancer with known tumor differentiation grade. Multivariable analyses were performed to assess independent associations between tumor differentiation grade and survival. Results: A total of 31,536 women were identified including 15,175 (48.1%) with grade 3 tumors, 14,084 (44.7%) with grade 2 neoplasms and 2,277 (7.2%) with grade 1 tumors. Higher tumor grade was significantly associated with older age, higher stage disease, larger tumor size, and lymph node metastasis (all, p<0.001). In a multivariable analysis, grade 2 tumors (adjusted-hazard ratio [HR]=1.21; p<0.001) and grade 3 tumors (adjusted-HR=1.45; p<0.001) were independently associated with decreased cause-specific survival (CSS) compared to grade 1 tumors. Among the 7,429 women with stage II-III disease who received radiotherapy without surgical treatment, grade 3 tumors were independently associated with decreased CSS compared to grade 2 tumors (adjusted-HR=1.16; p<0.001). Among 4,045 women with node-negative stage I disease and tumor size ${\leq}4cm$ who underwent surgical treatment without radiotherapy, grade 2 tumors (adjusted-HR=2.54; p=0.028) and grade 3 tumors (adjusted-HR=4.48; p<0.001) were independently associated with decreased CSS compared to grade 1 tumors. Conclusion: Our study suggests that tumor differentiation grade may be a prognostic factor in women with squamous cervical cancer, particularly in early-stage disease. Higher tumor grade was associated with poorer survival.

  • 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.

  • 귀전우(Euonymus alatus Sieb.)가 간암, 식도암, 위암, 자궁암등의 각종 암을 치료하는 방법으로 민방에서 많이 사용하고 있다. 실제 Euonymus alatus(Thumb.) Sieb의 추출물중 Eupolyphaga simensis(ES)는 HDL-C/TC ratio와 LCATactivity를 증진시킨다. Human hepatoblastoma 세포인 Hep3B 세포의 성장억제를 유도하는 factor로는 TGF-${\beta}$, Insulin 등으로 알려져 있다. 따라서 귀전우는 간에 있어 당 대사에 관여하는 plasma HDL3-C level은 낮게 유지함으로써 간에서 지방간 이행을 억제 하여 간에서의 암 발생을 억제하는 효과를 보인다. 실험에서 귀전우가 자궁암세포보다도 간암세포에 보다 높은 세포독성을 보임으로써 여러종류의 암에 모두 적용하기는 어렵다고 보여진다. 또한 귀전우가 바이러스에 의해 유도되는 간암과 hepatocellular Carcinoma 세포에서 효과가 있는지와 HCC에서 세포의 증식억제효과를 어떤 경로를 통해 이루어지는지 계속적으로 연구가 수행되어져야 될 것이다.

  • 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.
