[Long-term outcomes of 125I brachytherapy combined with maximal androgen blockade for metastatic prostate cancer].

OBJECTIVE: To investigate the long-term clinical value of prostate 125I brachytherapy (BT) combined with maximal androgen blockade (MAB) in the treatment of metastatic prostate cancer (mPCa). METHODS: We retrospectively analyzed the clinical data on 173 cases of mPCa treated by MAB (n = 126) or BT+MAB (n = 47) from December 2011 to December 2016 and followed up for 6－76 (44.17 ± 19.73) months. We compared the PSA level, prostate volume, IPSS, progression-free survival, and the rates of 3- and 5-year overall survival between the two groups. RESULTS: After treatment, the minimum PSA level was significantly lower in the BT+MAB than in the MAB group ï¼»3.77 ± 4.14ï¼½ vs ï¼»5.96 ± 7.01ï¼½ ng/ml, P = 0.046) and the time to reach the minimum level was shorter in the former than in the latter (ï¼»5.19 ± 2.83ï¼½ vs ï¼»6.52 ± 3.34ï¼½ mo, P = 0.016). The prostate volume was markedly reduced in both of the groups at 1, 3 and 5 years after treatment as compared with the baseline, even more significantly in the BT+MAB than in the MAB group (P < 0.01), though with no statistically significant difference between the two groups before treatment (P = 0.307). The IPSS was remarkably decreased in both of the groups at 1 and 3 years (P < 0.01) but showed no significant difference at 5 years after treatment as compared with the baseline (P > 0.05) or between the two groups before and after treatment (P > 0.05). The progression-free survival was obviously longer in the BT+MAB than in the MAB group (ï¼»37.29 ± 15.73ï¼½ vs ï¼»29.41 ± 14.37ï¼½ mo, P = 0.011), and the rates of 3- and 5-year overall survival were higher in the former than in the latter (74.60% and 60.70% vs 62.60% and 51.50%, P = 0.227 and P = 0.356). Kaplan-Meier survival curves showed no statistically significant difference in the overall survival between the two groups (P = 0.105). CONCLUSIONS: Both MAB and BT+MAB are effective therapies for mPCa, but the latter can achieve a longer progression-free survival.

A comprehensive review and meta-analysis comparing robot-assisted and laparoscopic adrenalectomy in individuals with obesity.

This meta-analysis aimed to compare the efficacy of robot-assisted vs. laparoscopic adrenalectomy in individuals with obesity. We performed an extensive review of the PubMed, Embase, and Cochrane Library databases for research on adrenalectomy in individuals with obesity up to August 2024. Only studies comparing robot-assisted surgery with laparoscopic surgery were included. Only articles written in English were included. We utilized established criteria for inclusion and exclusion, concentrating on randomized controlled trials and cohort studies. The ROBINS-I instrument was employed to assess the bias risk in non-randomized control studies. Review Manager 5.4.1 was utilized to conduct the meta-analysis. The final analysis incorporated four retrospective cohort studies with a total of 492 individuals with obesity (261 receiving RA and 231 undergoing LA). The results showed that RA was linked to a shorter duration of hospitalization and less estimated blood loss in comparison to LA. Nonetheless, there were no notable distinctions between the two surgical methods in terms of OT, laparotomy conversion rates, overall postoperative complications, or death rates after surgery. In conclusion, RA is a reliable and safe choice for individuals with obesity. It offers notable advantages over LA in terms of LOHS and EBL.

Comprehensive analysis of anoikis-related long non-coding RNA immune infiltration in patients with bladder cancer and immunotherapy.

Background: Anoikis is a form of programmed cell death or programmed cell death(PCD) for short. Studies suggest that anoikis involves in the decisive steps of tumor progression and cancer cell metastasis and spread, but what part it plays in bladder cancer remains unclear. We sought to screen for anoikis-correlated long non-coding RNA (lncRNA) so that we can build a risk model to understand its ability to predict bladder cancer prognosis and the immune landscape. Methods: We screened seven anoikis-related lncRNAs (arlncRNAs) from The Cancer Genome Atlas (TCGA) and designed a risk model. It was validated through ROC curves and clinicopathological correlation analysis, and demonstrated to be an independent factor of prognosis prediction by uni- and multi-COX regression. In the meantime, Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis, immune infiltration, and half-maximal inhibitory concentration prediction (IC50) were implemented with the model. Moreover, we divided bladder cancer patients into three subtypes by consensus clustering analysis to further study the differences in prognosis, immune infiltration level, immune checkpoints, and drug susceptibility. Result: We designed a risk model of seven arlncRNAs, and proved its accuracy using ROC curves. COX regression indicated that the model might be an independent prediction factor of bladder cancer prognosis. KEGG enrichment analysis showed it was enriched in tumors and immune-related pathways among the people at high risk. Immune correlation analysis and drug susceptibility results indicated that it had higher immune infiltration and might have a better immunotherapy efficacy for high-risk groups. Of the three subtypes classified by consensus clustering analysis, cluster 3 revealed a positive prognosis, and cluster 2 showed the highest level of immune infiltration and was sensitive to most chemistries. This is helpful for us to discover more precise immunotherapy for bladder cancer patients. Conclusion: In a nutshell, we found seven arlncRNAs and built a risk model that can identify different bladder cancer subtypes and predict the prognosis of bladder cancer patients. Immune-related and drug sensitivity researches demonstrate it can provide individual therapeutic schedule with greater precision for bladder cancer patients.

[Laparoscopic excision of seminal vesicle cyst].

OBJECTIVE: To investigate the method and clinical efficacy of laparoscopic excision of seminal vesicle cyst. METHODS: Laparoscopic excision of seminal vesicle cyst was performed under general anaesthesia in two patients with symptomatic seminal vesicle cyst confirmed by ultrasonography and CT scanning preoperatively. The sizes of the seminal vesicle cysts were 3.3 cm x 3.7 cm x 2.5 cm and 4.1 cm x 4.3 cm x 5.3 cm, respectively. RESULTS: The operations were performed successfully in both the patients, with the operation time of 140 min and 100 min, blood loss of 50 ml and 20 ml, and postoperative stay of 6 days. The patients were followed up for 6 and 7 months, respectively. All the preoperative symptoms disappeared, and no complications and recurrence were found. CONCLUSION: Laparoscopic excision of seminal vesicle cyst, with a good visual field, refined procedure, minimal invasiveness and rapid recovery, is a safe and effective surgical option for patients with seminal vesicle cyst.

Treatment of urinary lithiasis following kidney transplantation with extracorporeal shock-wave lithotripsy.

BACKGROUND: The incidence of urinary lithiasis following kidney transplantation is very low, and decision-supporting data are not available. The aim of this study was to review the diagnosis and treatment of urinary lithiasis following kidney transplantation, which is of realistic significance to reduce urinary lithiasis following kidney transplantation, prolong the survival of renal allografts. METHODS: The incidence, diagnosis and treatment of urinary lithiasis in ten patients following kidney transplantation were analyzed retrospectively. Seven out of these patients had stones sized approximately 0.4 - 1.1 cm, and they were treated with low-voltage, low-frequency extracorporeal shock-wave lithotripsy (ESWL). Two patients had stones sized < 0.3 cm and they underwent cystoscopy and ureteroscopy. The ureteral catheter endoscopes were inserted in a retrograde manner to mobilize stones repeatedly. After elimination of obstruction, a ureteral double J stent was indwelt. One patient had a pelvic stone (1.2 cm), which was removed surgically. RESULTS: The major clinical manifestations were hematuria, oliguria or anuria. Some patients were asymptomatic and they were diagnosed through laboratory tests and imaging examinations, e.g., ultrasonography. After elimination of obstruction, subjective symptoms disappeared in all patients, and the function of renal allografts recovered. A six-month follow-up indicated no remnant stones or lithiasis relapse. CONCLUSIONS: The diagnosis and treatment of renal allograft lithiasis are challenging. After prompt and appropriate treatment, the prognosis was satisfactory, and permanent renal functional impairment did not occur in most patients.
