Objective To explore the color Doppler ultrasonic characteristics of testicular Leydig cell tumors (LCT) and improve the clinical diagnosis of the disease. METHODS We retrospectively analyzed 4 cases of testicular LCT diagnosed and treated in our hospital and summarized the experience in the ultrasonic diagnosis of LCT with a review of the relevant literature. RESULTS All the 4 testicular LCTs were solitary and quasi-round, 1 in the left and 3 in the right. The smallest mass was 1.8 × 1.5 cm and the largest 3.1 × 2.5 cm, and 2 were complicated by hydrocele of tunica vaginalis. The margins of tumors were distinct in 2 cases and indistinct in 1, and changed from distinct to indistinct in another during the follow-up. Hypoechoes were revealed in all the 4 cases in ultrasonography, 2 with abundant internal blood flow, 1 with abundant peripheral blood flow, and the other with abundant internal blood flow changed from circular blood flow surrounding the mass. CONCLUSIONS A typical sporadic LCT was ultrasonically manifested as an isolated hypoechoic infracentimetric mass with a clear demarcation from the adjacent pulp. It exhibited intrinsic hypervascularization associated with a typical peripheral rim pattern. Larger lesions more often presented a lobulated shape and intense hypervascularization. Although these ultrasonic characteristics do not reveal the nature of LCT with certainty, they can help the surgeon with the decision on testis-sparing surgery or perhaps even on the active monitoring for the smallest lesions in a population with impaired fertility.Objective To study the clinicopathological characteristics of non-Hodgkin lymphoma (NHL) of the prostate. METHODS We collected the clinical data on 6 cases of NHL of the prostate pathologically confirmed between 2001 and 2017. The patients were aged 49－76 (median 62) years old, with the main clinical manifestations of painless swelling of the prostate and lower urinary tract obstruction. We analyzed the clinical features and the results of histological detection, immunohistochemical staining and B-cell gene rearrangement assay, and explored the clinicopathological characteristics and differential diagnosis of the disease based on the relevant literature. RESULTS Histological detection revealed diffuse large B-cell lymphoma (DLBCL) in 4 cases (66.7%), B-lymphoblastic lymphoma (B-LBL) in 1 (16.7%), and Burkitt lymphoma (BL) in another (16.7%). DLBCL was histologically characterized by diffuse oval or round medium-to-large-sized lyphoid cells with an infiltrative growth pattern, B-LBL by monotonous small-to-medium-sized lymphoid cells with prominet mitosis and apoptosis, and BL by diffuse and monotonous medium-sized neoplastic cells with round or oval nuclei, an infiltrative growth pattern, scanty cytoplasm and visible mitosis. One of the DLBCL patients received 5 doses of R-CHOP chemotherapy and has been followed up to the present time, while the other 3 were lost to follow-up; the B-LBL patient died at 1 month after diagnosis; and the BL patient gave up treatment.

METHODS From June 2009 to September 2016, we treated 20 cases of PCa liver metastases by Cyberknife SBRT, at a total dose of 36 (30－50) Gy, on 1－3 liver metastatic lesions, for 3－5 times, with a prescription isodose line of 70－92%. We assessed the therapeutic effect according to the modified Response Evaluation Criteria in Solid Tumors (mRECIST), calculated the survival and disease-control rates using the Kaplan-Meier method, and analyzed the adverse events based on the National Cancer Institute Common Terminology Criteria for Adverse Events－Version 4.0 (CTCAE 4.0). RESULTS Of all the cases treated, complete response (CR) was found in 8 (40.0%), partial response (PR) in 9 (45.0%), stable disease (SD) in 2 (10.0%), and progressive disease (PD) in 1 (5.0%), with a local control rate (CR+PR) of 85.0% and a disease-control rate (CR+PR+SD) of 95.0%. Among the 14 patients with elevated PSA, 10 (71.4%) showed a significant decrease after treatment. The median follow-up time was 17 months, the 1- and 2-year survival rates were 85.0% and 15.0%, respectively, and the median survival time of the 20 patients was 16.5 months (95% CI 12.12－22.88). Cyberknife SBRT was well tolerated in all the patients, with only a few mild adverse events (mainly grades 1 and 2 but no 4 and 5) during the whole course of treatment. CONCLUSIONS Cyberknife SBRT is safe and effective in the treatment of PCa liver metastases, with a high local control rate, and capable of reducing the PSA level and raising the long-term survival rate of the patients.Objective To investigate the attitudes of prostate cancer (PCa) patients towards postoperative penile rehabilitation and their influencing factors. METHODS Seventy-nine PCa patients underwent radical prostatectomy from January through June 2017 and all received a questionnaire investigation before surgery on IIEF-5 and their attitudes towards postoperative penile rehabilitation. We analyzed the reasons for the patients' rejection of postoperative penile rehabilitation. RESULTS Totally 56 (71%) of the patients accepted and the other 23 (29%) refused postoperative penile rehabilitation. The factors influencing their attitudes towards penile rehabilitation mainly included age (P = 0.023), income (P = 0.040), tumor stage (P = 0.044), and preoperative sexual activity (P = 0.004). The patients who accepted penile rehabilitation had significantly higher IIEF-5 scores than those who refused it (14.75 ± 0.88 vs 8.48 ± 1.16, P = 0.000 2). During the follow-up period, only 29 (36.7%) of the patients bought the vacuum erection device but not the other 50 (63.3%). The tumor stage (P = 0.004), income (P less then 0.01) and preoperative androgen-deprivation therapy (P = 0.039) significantly influenced the patients' decision on the purchase of the device. Relevant admission education achieved a 45% decrease in the number of the patients unwilling to accept penile rehabilitation for worrying about its negative effect on cancer treatment, a 25% decrease in those rejecting penile rehabilitation because of age, and a 20% decrease in those refusing it due to the tumor stage. The cost of treatment was an important reason for the patients' rejection of postoperative penile rehabilitation. CONCLUSIONS The tumor stage and income are the main factors influencing PCa patients' decision on postoperative penile rehabilitation. Relevant admission education and reduced cost of rehabilitation are important for popularization of postoperative penile rehabilitation in PCa patients.
