Résumé

OBJECTIVE: This study was performed to evaluate the overall survival and the change in treatment modalities in patients with uterine endometrial cancer in Korea. METHODS: From January 1990 to March 2005, medical records of 740 patients with endometrial cancer in nine hospitals were reviewed. The overall survival was determined supported by the death statistics of Korea National Statistical Office. RESULTS: The mean age of patients was 51.5 years (range: 21-82 years). The mean gravidity and parity were 3.3 and 2.1 (range: 0-18, 0-9), respectively. The most common stage, grade and histological type at diagnosis were FIGO stage I, grade 1 and endometrioid adenocarcinoma (76.5%, 56.4% and 87.2%), respectively. The main treatment modalities was surgery on stage I (59.8%), surgery-adjuvant radiotherapy on stage II (55.1%), surgery-adjuvant radiotherapy or surgery-adjuvant chemoradiation on stage III (38.3%) and surgery-adjuvant chemotherapy on stage IV (55.6%). The preferred treatment modality was surgery only on grade 1 (69.0%) and surgery-adjuvant radiotherapy on grade 2-3 (43.4% and 53.2%). Surgery had been the most common method of therapy before 1998 but its prevalence gradually decreased. As a result, surgery-adjuvant radiotherapy and surgery-adjuvant chemotherapy were most widely performed in 2004-2005 and surgery-adjuvant chemoradiation also increased more than a twofold. The overall 5 years survival rate (5YSR) for all 740 patients was 81.3%. The overall 5YSR of stage I was 89.0%. The overall 5YSR of grade 1, grade 2, grade 3 were 96.0%, 92.0%, 80.0%. Before 1998, the survival rate was 77.0%. Since then it increased to 83-88% and in 2000-2001 it increased to 88.0%, and it was the highest survival rate. CONCLUSION: The survival rate of endometrial cancer has been improving for the past 15 years and the method of treatment is also being changed currently. In order to improve the survival rate of endometrial cancer, a close investigation including genetic and environmental factors of the pathophysiology of endometrial cancer along with the epidemiology of risk factors, should be carried out.

Résumé

The gene encoding E7 oncoprotein of human papillomavirus type 16 was cloned and expressed in Escherichia coli, and the monoclonal antibodies (Mabs) against this expressed protein were generated. For the efficient immunization, two kind of recombinant E7 protein in fusion form were produced. One was maltose binding protein (MBP) fusion type (MBP-E7) and the other was T7 phage gene 10 product fusioa type (gene 10-E7). Immunization with these two fusion protein to mice, finally two Mabs (VD6 and IB10) were obtained. VD6 and IB10 showed reactivities with E7 protein in CaSki cell but not in HeLa by Western blot analysis. In addition, the Mab, VD6, reacted with COS-7 cell transfected with E7 gene majorly in cytoplasm by immunofluorescence test. Also VD6 could detect E7 protein in cytoplasm and nucleus of CaSki ceU by immunogold electron microscopy. Based on these results, the Mab VD6 was could be used for various E7 detection system such as Western blot analysis and immunohistochemical methods.
