Objective To evaluate the value of postoperative prophylactic radiotherapy for N0 e-sophageal squamous carcinoma. Methods From January 1993 to December 2006,859 patients with patho-logically staged N0 and M0 esophageal squamous cell carcinoma were included in this study. Among them, 760 received surgery alone, and 99 received surgery followed by postoperative radiotherapy. Radiotherapy started within 3 to 4 weeks after surgery. The median total dose was 50 Gy(2 Gy/F,5 F/w). Results In surgery alone group and postoperative radiotherapy group,the 5-yeur overall survival rotes were 72.2% vs 77.4% (X2 =0. 13,P >0.05) for all patients,34.6% vs67.1% (X2 =7.72,P <0.05) forpT4 disease,and 70.2% vs 81.3% (X2 =4.01 ,P <0.05) for tumor length >5 cm. Postoperative radiotherapy could lower the recurrence rate for pT4 patients. Conclusions For patients with NO esophageal squamous carcinoma, postoperative radiotherapy can significantly improve the survival for pT4 and tumor length > 5 cm,and also re-duce the recurrence for pT4 patients.

Objective To analyze the relationship between the number as well as distributions of positive lymph nodes, and the clinical outcomes of postoperative radiotherapy for thoracic esophageal squamous cell carcinoma (TESCC) , And to evaluate the efficacy of postoperative radiotherapy . Methods From January 1993 to March 2007,945 patients with TESCC treated with three-field lymphadenectomy were involved in this study. All patients were with lymphoid metastasis but without distant metastasis. Among them, 590 patients received surgery alone and the other 355 received surgery plus postoperative radiotherapy. The radiotherapy were begun in the third or fourth week after operation and the median total radiation dose was 50 Gy in 25 fractions of 2 Gy, 5 fractions per week. Results The follow-up rate was 94.5%. 189 patients finished minimal follow-up of five years. The 5-year survival rates in the surgery alone group and in the postoperative radiotherapy group were 29.6% and 38.0%, respectively (χ~2 = 10.44 ,P = 0.001). In stratification analysis, compared with the surgery alone, postoperative radiotherapy could increase the 5-year survival rate of the patients with 3 to 5 (30.5% : 23.1%, χ~2 = 4.11, P = 0.043) or > 5 positive nodes (16.7% : 8.9%, χ~2= 6.87, P= 0.009) , or metastastatic node in the region of supraclavicular or upper mediastinum (45.5% : 34.9%, χ~2= 5.37, P = 0.020). In patients with positive nodes number less than 3, or with medium mediastinum or lower mediastinum lymph nodes metastasis, postoperative radiotherapy could not increase the 5-year survival rates (50.7% : 41.2%, χ~2 = 3.30, P = 0.069 ; 32.0% : 27.7% , χ~2= 2.22 , P = 0. 137) , Though could decrease lymph nodes metastasis in supraclavicular and medium-upper mediastinum (15 : 76, χ~2 = 18.10, P = 0.000; 18 : 97, χ~2= 26.81, P = 0.000). Conclusions In TESCC patients with positive lymph nodes number ≥3 or nodes in the region of supraclavicular and upper mediastinum, postoperative radiotherapy can improve the survival after three field lymphadenectomy. And the rate of metastastatic lymph nodes in the supraclavicular region or upper-medium mediastinum can also be decreased.

Objective To investigate the effect of occupational therapy on motor function of upper limbs and activities of daily living(ADL)of patients with hemiplegia.Methods 51 patients with hemiplegia were randomly divided into the treatment group(n=26)and control group(n=25).Both two groups were received routine training,and besides,patients in the treatment group were added with occupational therapy.The motor function of upper limbs was evaluated by Fugl-Meyer scale before and after treatment,and ADL and hand function were also evaluated at same time.Results After treatment,the scores of Fugl-Meyer scale,ADL and hand function of all patients in two groups improved(P<0.05),but the therapeutic effect of the treatment group was superior to the control group(P<0.05).Conclusion The occupational therapy can strengthen the upper limbs and hands function,and effectively improve fine motors.

Objective To compare the accuracy of CT with other methods to measure the length of thoracic esophageal carcinoma. Methods 598 patients with thoracic esophageal squamous carcinoma were enrolled in this study.All the patients received three-field(cervical,thoracic:and abdominal)radical surgery without pre-operative radiotherapy or chemotherapy.The length of each Iesion was recorded and compared by measuring intraoperative specimen,formalin-fixed specimen,X-ray barium meal examination and CT,respectivelv. Results By the measurement of intraoperative specimen,formalin-fixed specimen,Xray barium meal examination and CT,the mean lengths of lesion were(5.22±1.94),(4.28±1.71),(5.12±1.92)and(6.71±2.52) cm,respectively.The measured length was significantly different between intraoperative specimen and formalin-fixed specimen or CT(t=16.01,P＜0.01;t=-15.54,P＜0.01),but not between intraoperative specimen and X-ray barium meal examination(t=1.62,P＞0.05).The measured lengths gradually decreased in the order of CT,intraoperative specimen,X-ray bailam meal examination and formalin-fixed specimen.For different pathological type(except intracavitary type)and different T staging,there was significant difference in lesion length between intraoperative specimen and CT(P＜0.05),but not between intraoperative specimen and X-ray barium meal examination(P＞0.05). Conclusions The length of esophageal carcinoma measured by intraoperative specimen is shorter than by CT,but longer than by X-ray barium meal examination.Specimen could shrink after foriBalin fixation.X-ray barium meal and other examinations should be referred when using CT to delineate tumor target volume of esophageal carcinoma for radiotherapy.

Objective To assess the effects of the risk factors of grafts from donors after cardiac death (DCD) on the prognosis of liver transplantation (LT).Methods In this retrospectively study,215 cases of LT using DCD donor grafts were performed at our institution from September 2013 to January 2017.Due to the loss to follow-up in 4 cases,211 cases were enrolled in the study.The following DCD donor data were collected:gender,age,primary disease,ABO blood type,body mass index (BMI),medical history (fatty liver,hypertension),ICU hospitalization time,mechanical ventilation time,warm ischemia time,cold ischemia time,and indexes of routine laboratory test before donation.Statistical analyses using the Kaplan-Meier method,log-rank test,multivariate step-wise Cox regression were performed.Results Of the 211 donors,univariate analysis showed that the overall 6-month,1-,and 3-year survival rate after DCD LT was 88％,84％,and 82％,respectively.Univariate analysis showed that donor serum sodium level ＜136 mmol/L (P =0.018) and cold ischemia time ＞9 h (P =0.013) were all significant risk factors affecting overall survival after DCD LT.Additionally,donor BMI ＞30 kg/m2 (P =0.011) and donor age ＞60 years (P =0.025) were significantly associated with postoperative complications.Multivariate analysis showed that donor serum sodium level (P=0.025) was an independent risk factor of survival after DCD LT.Conclusion To select suitable DCD liver allografts and control risk factors of donor can help to improve outcomes of recipients.
