Purpose:To study prognostic factors of younger women's eptihelial ovarian neoplasms.Methods: From Jan. 1980 to Dec. 1992, there were 86 cases of younger women's epithelial ovarian carcinoma in our hospital. We studied serveral prognostic factors retrospectively.Results:In this setting, 2 year survival rate were 79.07%, 5 year survival rate were 54.65%. There were 49 cases with stage Ⅰ and 41 cases with grade Ⅰ. No recurrence was found in 4 patients who preserved ovarian function. Cox model multifactor results showed that grade, residual tumor size and the method of surgery were prognostic factors( P 0 05). The pathological type, FIGO staging, grade, residual tumor size, the method of surgery were important factors according to unifactor analyze ( P

Objective To establish the methods of three-dimensional eonformal(3DCRT) and intensity-modulated radiotherapy(IMRT) for whole pelvic irradiation in post-hysterectomy cervical carcinoma, And to optimize the methods for clinical practice. Methods Between 2004 and 2005,10 patients with cervical carcinoma who underwent hysterectomy with high risk of recurrence were selected for this study. The following observations and measurements were used for the study: Set-up errors with supine or prone position were measured to determine appropriate immobilization position. Influence of full and empty bladder on irradiated normal tissue volume was measured. Treatment errors were detected and CTV/PTV were then delineated. 3DCRT and IMRT planning and comparison were applied. Results The set-up error was within 5 mm of three dimensions in prone position and more than 5 mm in supine position, the difference of which was statistically significant. The percentage of irradiated volume of the bladder and bowel was smaller when the bladder was full comparing with empty bladder. In prone position and with full bladder,portal films showed the movement of isocenter in three directions. The total uncertainty was [7.4±1.6]mm. For 95% confidence interval,the margin from CTV to PTV was 1 cm. CIPTV for 3,4,5,and 6 fields 3DCRT was 0.46,O. 67, O. 68, and O. 68, respectively. When beyond 4 fields, the advantage of adding fields was not significant.Four fields planning was feasible for clinical practice. CI for 5,7,9,11 ,and 13 fidds IMRT was 0.75,0.83, 0.84,0.85 ,and 0.85 ,respectively. When beyond 9 fields,the advantage of adding fields was not significant. Nine fields planning was feasible for clinical practice. Conclusions For whole pelvic radiotherapy for post-hysterectomy cervical carcinoma,prone position was better than supine position for immobilization due to smaller set-up errors. The full bladder is recommended during radiotherapy, planning,For clinical practice,4 fields planning is feasible in 3DCRT while 9 fields planning is feasible in IMRT.

Objective:To investigate the correlation between cardiac polyps and gastroesophageal flap valve (GEFV).Methods:The clinical, endoscopic and pathological data of 349 patients with cardiac polyps (the cardiac polyp group) visiting Affiliated Hospital of Yangzhou University from January 1, 2016 to December 31, 2021 were retrospectively collected, and the same number of non-cardiac polyp patients (the non-cardiac polyp group) were matched in the same period as control according to the propensity score. The clinical, endoscopic and pathological data of the two groups were compared.Results:After matching with propensity score, there were 296 patients in each group, with no significant differences in smoking, acid reflux, heartburn, Helicobacter pylori infection, bile reflux, reflux esophagitis or pancreatitis between the two groups ( P>0.05). Compared with the non-cardiac polyp group, the risk of cardiac polyps increased in GEFV Ⅱ patients ( OR=3.046, 95%CI: 2.100-4.419, P<0.001) and GEFV Ⅲ patients ( OR=4.202, 95%CI: 2.299-7.681, P<0.001). Compared with the non-cardiac polyp group, the risk of cardiac polyps increased in patients with GEFV abnormalities ( OR=2.822, 95%CI: 1.615-4.931, P<0.001). GEFV abnormalities was associated with the cardiac polyp site ( χ2=22.169, P=0.003) and was not significantly associated with cardiac polyp size, number, morphology, intestinal metaplasia of the surrounding mucosa or intraepithelial neoplasia ( P>0.05). Conclusion:The occurrence of cardiac polyps is related to GEFV, and the patients with GEFV abnormalities are more likely to develop cardiac polyps.

Objective:To investigate the safety and risk factors of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) for pancreatic lesions.Methods:Five thousand one hundred and sixty patients who underwent EUS-FNA in the Department of Endoscopy, Fudan University Shanghai Cancer Center from January 2012 to December 2022 were retrospectively reviewed. The incidence of adverse events was calculated, and independent risk factors were analyzed by univariate and logistic regression.Results:The incidences of postoperative pancreatitis, intraoperative bleeding and postoperative bleeding were 1.38% (68/4 930), 0.82% (42/5 143) and 0.78% (40/5 143) respectively. No perforation or death occurred. Age >60 years ( OR=0.581, 95% CI: 0.356-0.946, P=0.029), tumor located in the neck, body and tail ( OR=0.355, 95% CI: 0.194-0.652, P=0.001), lesion diameter of >20-40 mm ( OR=0.450, 95% CI: 0.227-0.893, P=0.023), and lesion diameter >40 mm ( OR=0.382, 95% CI: 0.168-0.869, P=0.022) were independent protective factors for postoperative pancreatitis. Transduodenal puncture ( OR=2.435, 95% CI: 1.319-4.496, P=0.005) was an independent risk factor for postoperative pancreatitis. Puncture for 3-4 pass ( OR=0.439,95% CI: 0.235-0.821, P=0.010), lesion diameter of >20-40 mm ( OR=0.154, 95% CI: 0.069-0.341, P<0.001), and lesion diameter >40 mm ( OR=0.326, 95% CI: 0.143-0.743, P=0.008) were independent protective factors for intraoperative bleeding. Fine-needle biopsy (FNB) needle ( OR=2.314, 95% CI: 1.189-4.502, P=0.014) was an independent risk factor for postoperative bleeding. Conclusion:EUS-FNA is a safe procedure with low incidence of adverse events. The occurrence of postoperative pancreatitis and intraoperative bleeding is mainly related to clinical characteristics of the lesion, while postoperative bleeding is related to the type of puncture needle.
