Comparing with the world level, the bibliometric indicators of Chinese medical journals in oncology field are rather lower, but our medical journals have big development space. In the world journals with high impact index, the papers published by Chinese authors are fewer; in the papers number, the superiority of Chinese authors is in tumor clinical therapy field. Most papers are written by researchers from large institutions with plenty of medical resources.

Objective To summarize the clinical experience of retroperitoneal and transperitoneal laparoscopic adrenalectomy for adrenal tumors.Methods Laparoscopic adrenalectomy was carried out in 56 cases of adrenal tumors via transperitoneal(10 cases) or retroperitoneal(46 cases) approaches.For transperitoneal laparoscopic adrenalectomy,the operation was performed through 3 abdominal trocars.After the peritoneum and the Gerota's fascia were opened,the adrenal gland or tumor were disconnected near the upper polar of the kidney.Then the tumor was removed by using the LigaSure system and a harmonic scalpel.For retroperitoneal laparoscopic adrenalectomy,a self-made balloon was used to dilate the retroperitoneal space.Then the Gerota's fascia was opened and the tumor was removed by using the LigaSure system and a harmonic scalpel. Results Of the 10 cases of transperitoneal adrenalectomy,conversions to open surgery were required in 3 cases because of extensive abdominal adhesion;of the 46 cases of retroperitoneal adrenalectomy,a conversion to open surgery was needed in 1 case because of massive hemorrhage of the inferior vena cava.Of the remaining 52 cases,the intraoperative blood loss was 20~200 ml(mean,70 ml) and no blood transfusion was needed.The operation time was 40~200 min(mean,110 min).The postoperative hospital stay was 3~8 d (mean,5.4 d).Follow-up for(6~36) months(mean,8 months) in 52 cases showed no tumor recurrence and metastasis.Conclusions Laparoscopic adrenalectomy has advantages of reliable effects,minimal invasion,rapid recovery,and short hospital stay.This procedure can be used as the first choice for the treatment of adrenal tumors.

Mutations of BRCA1 and BRCA2 are closely related to developing of breast cancer andovarian cancer. There are a great diversity of founder mutations of BRCA1 and BRCA2. Their types and fre quency are greatly different in populations from different geographic regions and ethnicities. In particular ethnicgroups, founder mutations show a high frequency due to a founder effect. Compared with the expensive wholegenomic scan, screening of founder mutations which could provide information for the prevention and treatmentof related cancer is more convenient and easy to popularize with low cost.
