Tumor 2014;34(10):952-956
Objective: To evaluate the diagnosis, treatment and prognosis of patients with synchronous primary endometrial and fallopian tube cancers. Methods: The clinical records of four cases of synchronous primary endometrial and fallopian tube cancers from Jiangxi Maternal and Child Health Hospital between October 2008 and October 2013 were reviewed. The follow-up was performed in all patients. The date of last contact was June 30, 2014. Results: The preoperative diagnosis for four cases was endometrial cancer. Two of them underwent extensive abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic lymphadenectomy and para-aortic lymph node biopsy, and the other two cases underwent extrafascial abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic lymphadenectomy and para-aortic lymph node biopsy. The postoperative diagnosis for four cases was stage IA endometrioid adenocarcinoma and stage IA/IB fallopian tube adenocarcinoma. Three patients received 1-3 cycles of chemotherapy of docetaxel plus platinum, and one patient didn't receive any chemotherapy. The follow-up time was 38-71 months. All patinets remained tumor-free survival by June 30, 2014. Conclusion: The patients with synchronous primary stage I endometrial cancer and stage I fallopian tube cancer has a good prognosis, and the extensive/extrafascial abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic lymphadenectomy and para-aortic lymph node biopsy are appropriate surgical procedures for these patients. The necessity of postoperative chemotherapy should be further explored.

Case teaching method has been widely used in clinical medicine teaching.Because of the complicated diseases in elderly patients and the individual differences,it is difficult to achieve the goal of teaching only through several cases.Typical cases of different level are selected according to students' different learning stages and difficulty degree in longitudinal stepped case teaching.The students can gradually understand and master the theoretical knowledge through this method.In addition,their clinical thinking and the ability of solving practical problems can also be trained continuously.Preliminary practice shows that this teaching method is more suitable for the development of modern medical education and the needs of teaching.

Purpose To investigate the clinicopathological and immunohistochemical features of primary renal lymphomas ( PRL) , and to discuss the diagnosis, differential diagnosis, treatment and prognosis of the tumors. Methods Clinical data of 19 patients with PRL from January 2005 to October 2014 were retrospectively analyzed. Result The 19 patients in this study, there were 11 males and 8 females and the age ranged from 37 to 85 years old (averaged 55). Patients were mainly presented with unilateral renal masses, with lumbodynia as the main symptom. 13 patients underwent nephrectomy, 6 patients underwent renal biopsy and 17 patients received CHOP or R-CHOP chemotherapy. All of them were diagnosed as non-Hodgkin’ s lymphoma, with 14 cases of diffuse large B cell lym-phoma (DLBCL) (73. 684%, 14/19), 4 cases of B cell small cell lymphoma (21. 053%, 4/19), and 1 cases of T cell lymphoma (5. 263%, 1/19). Follow-up information was available in 15 patients. 12 were still alive and survived for 1~78 months, while the other 3 were dead with 1 case who died of cerebral infarction, and survived for 3~38 months ( averaged 23 months) . Conclusion PRL is an extranodal lymphoma which is rare in kidney and is often misdiagnosed as renal carcinomas due to its nonspecific clinical manifestations. The diagnosis of PRL can be confirmed by histopathological examination, immunohistochemistry and molecular analy-sis. The majority of the lymphomas are B cell lymphomas and most of them are DLBCL. The recommended treatment is surgery com-bined with chemotherapy and the prognosis is associated with the age, clinicopathological characteristics, tumor types and treatment.

Objective To analyze the clinical efficacy of laparoscopic totally extraperitoneal hernia repair(TEP) and traditional hernia repair in the treatment of inguinal hernia. Methods 94 inguinal hernia patients admitted in our hospital from January 2014 to August 2017 were randomly divided into two groups. 45 patients in the control group received conventional hernia repair and 49 patients in the study group received laparoscopic totally extraperitoneal hernia repair. The clinical treatment effects between the two groups were compared. Results The overall incidence of complications in the study group was 4. 08%, which was lower than 17. 78% in the control group(P<0. 05). The hospitalization cost of the study group was higher than that of the control group. The hospitalization time, postoperative pain time and operation time in the study group was lower than that in the control group (P<0. 05). The recurrence rate (0%) in the study group was lower than 6. 67% in the control group(P<0. 05). There was no significant difference in SDSand SASscores between the two groups before treatment(P>0. 05). After treatment, the scores in the study group were lower than those in the control group(P<0. 05). Conclusion It is recommended to use TEPfor clinical treatment of inguinal hernia. Although this method is more expensive than conventional hernia repair, it can reduce the incidence of complications and make the disease recover quickly. It has great application value.
