Comparative Study[Clinical study of intensity modulated radiotherapy and three-dimensional conformal radiotherapy with three-dimensional brachytherapy and concurrent chemotherapy for patients with advanced cervical cancer].
Objective: To compare the dose, clinical efficacy and acute adverse reactions of intensity modulated radiotherapy (IMRT) and three-dimensional conformal radiotherapy (3D-CRT) combined with three-dimensional brachytherapy (3D-BT) in the treatment of concurrent radiotherapy and chemotherapy for advanced stage cervical cancer patients. Methods: Data collection was performed from January 2011 to November 2015 in Chinese PLA General Hospital and Inner Mongolia Cancer Hospital. All 89 patients with advanced stage (Ⅱ b-Ⅲ b) cervical cancer were treated by pelvic radiotherapy and concurrent chemotherapy, 46 cases of them received IMRT and 3D-BT (IMRT group) , 43 cases received 3D-CRT and 3D-BT (3D-CRT group) , along with cisplatin chemotherapy. ⋯ There were no significant differences in overall survival rate and progression-free survival rate between two groups (P>0.05). Conclusions: Compared with 3D-CRT, IMRT combined with 3D-BT has dosimetry advantages based on dose accumulation algorithms by deformable image registration. IMRT could ensure clinical efficacy and significantly reduce the incidence rate of acute toxicities.

[Significance and expression of PAX8, PAX2, p53 and RAS in ovary and fallopian tubes to origin of ovarian high grade serous carcinoma].
Objective: To explore the origin of ovarian high grade serous carcinoma (HGSC) through analysing the expression and significance of PAX8, PAX2, p53 and RAS in the ovary and fallopian tube of different types and grades of serous carcinoma. Methods: A total of 44 cases tissue samples of ovarian tumor including 34 malignant ovarian tumor and 10 normal normal tissue (as control group) were collected from the admitted patients in Affiliated Tumor Hospital of Guangxi Medical University from January 2015 to January 2016. Fallopian tube tissues were segmented in accordance with the fimbria, ampulla, isthmus and the corresponding ovarian tissues were by the side. ⋯ Conclusions: PAX8, PAX2, p53, RAS are of great significance for the study of origin of HGSC. HGSC may be derived from fallopian tube, but further investigation would be necessary to confirm this. PAX8, PAX2, p53, RAS could be expected to be used as predictors of survival prognosis in patients with ovarian serous cancer.
