Objective An attempt to develop a patient survey questionnaire on the public benefit nature of medical institutions as seen by patients,along with an evaluation of its reliability and validity.Methods A field survey was conducted among the patients visiting these institutions.The Cronbach's α coefficient was calculated to test the reliability.Factor analysis and spearman correlation analysis were applied to test the validity.The validity was also tested by analyzing the demographic factors and comparing the results between different kinds of medical institutions.Results The Cronbach's α coefficient of the questionnaire was 0.853,meanwhile the Cronbach's α coefficient of the three items was 0.845(quality of care),0.845 (suitability of services) and 0.752 (professional ethics).Three common factors were extracted,which coincided with the three items-quality of care,suitability of services and professional ethics.And the results are hardly affected by common demographic characteristics.Condusion The reliability of the questionnaire was acceptable,and the items were reasonably divided in the questionnaire with good structural validity.The questionnaire can be widely applied to evaluate the public benefit nature of medical institutions.

OBJECTIVETo evaluate the clinical value of prophylactic radiotherapy for esophageal carcinoma after curative operation.

METHODS495 esophageal squamous cell cancer patients who had undergone radical resection were randomized by the envelope method into a surgery alone group (S, 275) and a surgery plus radiotherapy group (S + R, 220). Radiation treatment was started 3 - 4 weeks after operation. The portals encompassed the whole mediastinum and bilateral supraclavicular areas. A mid-plane dose of 50 approximately 60 Gy in 20 approximately 30 fractions over 5 approximately 6 weeks was delivered.

RESULTS1. Survival rate: the overall 5-year survival rate was 39.4%. Those of S alone and S + R groups were 37.1% and 41.3% (P = 0.447 4). The 5-year survival rate for Stage III patients were 13.1% in S alone group and 35.1% in R + S group (P = 0.002 7), 2. Pattern of failure: The incidence of local recurrence intra-thoracic lymph node metastasis, anastomotic recurrence and extra-thoracic lymph node metastasis in S + R group (16.2%, 0.5% and 3.1%) were lower than those (25.9%, 5.8% and 13.2%) (P < 0.05) in S alone group and 3.

COMPLICATIONSthe anastomotic stricture frequencies were similar in the two groups (S 1.8%; S + R 4.1%).

CONCLUSION1. Prophylactic radiotherapy is able to improve the survival rate of stage III patients treated by radical resection, 2. Postoperative radiotherapy is able to reduce the incidence of failure by recurrence in the intra-thoracic lymph nodes and anastomotic recurrence to where radiation therapy had been given, 3. Postoperative radiotherapy does not increase the incidence of anastomotic stricture.

Objective To investigate the safety and efficacy of re-irradiation with stereotactic body radiotherapy(SBRT) for treating locally recurrent advanced pancreatic cancer.Methods From 2014 to 2017,7 patients with stage Ⅲ pancreatic cancer were treated by re-irradiated with SBRT at Shanghai Changhai Hospital.SBRT was delivered via the G4 type cyberknife robotic stereotactic radiosurgery system in all the patients.The median dose of the first SBRT was 35Gy/5-7 fx,and the median dose of re-irradiation with SBRT was 31 Gy/5-8 fx.6 patients had undergone sequential chemotherapy either with gemcitabine or S-1 based therapy except one patient who refused the chemotherapy.Results There were 5 male and 2 female patients.The median overall survival (OS) of 7 patients was 30 months.Patients were re-irradiated with SBRT after a median interval of 10 months after the first SBRT.Median OS and locally relapse-free survival (LFRS) from re-irradiation were 13 months and 11 months,respectively.Three months after re-irradiation,3(42.9％) patients had partial remission and 4 patients had stable disease.Pain disappeared in 4 patients at the end of reirradiation and significant pain was alleviated in 2 patients 1 month after re-irradiation.There were no toxicities of grade 3 or higher grade during two courses of SBRT.Conclusions For patient with locally recurrent advanced pancreatic cancer,SBRT re irradiation regimen was associated with acceptable toxicity,which can effectively alleviate the pain,prolong the survival and improve the life quality.
