今回我々はロボット支援腹腔鏡下腎尿管全摘除術(RNU)の初期経験を得た.対象は2019年7月から2020年7月にda Vinci Si(4例)またはXi(2例)サージカルシステムでRNUを受けた6症例.全例男性で患側は左4例,右2例,cT3の3例を含む4例で術前化学療法を施行した.完全側臥位,軽度ジャックナイフ体位,6または7ポート,経腹膜アプローチで手術を施行した.術中,体位変換やペイシェントカートの移動は行わなかった.手術時間の中央値は308分,推定出血量の中央値は63mLで輸血や開腹手術移行は無かった.pT3の左尿管癌症例1例で摘出標本断端が陽性であった.周術期合併症はClavien-dindo分類でGrade IIの乳糜腹水,下痢を1例ずつ認めた.RNUは手術手技の標準化とより多くの症例を対象とした長期追跡調査が必要であるが,UTUC症例に対する新たな治療選択肢となり得る.(著者抄録)

Missense polymorphism in HSD3B1, encoding 3β-hydroxysteroid dehydrogenase-1, was associated with outcome after abiraterone treatment. Other androgen-metabolizing enzymes may be involved in therapeutic effect in abiraterone. In this study, we investigated the significance of polymorphisms in genes involved in androgen and abiraterone metabolisms in prostate cancer patients treated with abiraterone. A total of 99 Japanese male castration-resistant prostate cancer patients treated with abiraterone between 2014 and 2018 were included. Genomic DNA was obtained from whole blood samples, and genotyping on SRD5A2 (rs523349), CYP17A1 (rs743572), CYP17A1 (rs2486758), and AKR1C3 (rs12529) was performed by PCR-based technique. Among the 99 patients, 32 (32.3%), 49 (49.5%), and 18 patients (18.2%) carried GG, GC, and CC alleles in SRD5A2, respectively. CC allele was associated with lower risk of treatment failure (hazard ratio, 0.43; 95% confidence interval, 0.20-0.87; P = 0.017) on multivariate analyses, compared with GG/GC alleles. In the combination model using HSD3B1 and SRD5A2 polymorphisms, compared with the combination of AA in HSD3B1 and GG/GC in SRD5A2, other combinations were associated with lower risk of treatment failure (hazard ratio, 0.34; 95% confidence interval, 0.17-0.62; P = 0.0003) on multivariate analyses. This study showed that SRD5A2 genetic variation was associated with the risk of treatment failure in abiraterone. Combinational use of genetic variation in HSD3B1 with SRD5A2 genetic variation augmented the ability of prognostic stratification.

A 73-year-old woman with no history of disease was referred to our hospital with fatigue and joint pain. Screening blood test showed that her cancer antigen 15-3 (CA 15-3) serum level was elevated to 36.6 U/mL, and a contrast-enhanced computed tomography scan revealed a bladder tumor without metastasis. Cystoscopy showed a papillary and a small kissing tumor, and the histopathological analysis of the bladder tumor obtained by transurethral resection (TUR) showed invasive urothelial carcinoma (UC) with micropapillary variant (pT1). At 4 weeks after TUR, the CA 15-3 serum level was markedly increased to 180.6 U/mL, and radiographic examinations revealed multiple regional and nonregional lymph node metastases. The patient received systemic therapy with gemcitabine and cisplatin. After 3 cycles of chemotherapy, the size of all lymph node metastases reduced by 80% in diameter, and the CA 15-3 serum level decreased from 238.2 to 11.4 U/mL. Immunohistological analysis showed that the bladder tumor was positive for mucin 1, of which CA 15-3 is an epitope. In our patient, changes in the CA 15-3 serum levels were in congruence with the clinical course of advanced micropapillary UC (MPUC). Therefore, the CA 15-3 serum level may be a potentially valuable biomarker for MPUC.

A 35-year-old male patient with end-stage renal disease due to vesicoureteral reflux preemptively received a renal graft from his father. The patient had a history of allergy to contrast-enhancing media. He received oral tacrolimus (TAC) and mycophenolate mofetil without any problems for 2 days before kidney transplantation. During the induction period of the surgery, his systolic blood pressure (sBP) decreased to 60 mmHg approximately 1 hour after initiating intravenous tacrolimus (TAC-IV) and intravenous piperacillin (PIPC), and the anesthesiologist suspected drug-induced anaphylaxis and stopped administration of the medications. Because TAC had been administered preoperatively without any adverse events, PIPC was suspected as the causative agent of the anaphylaxis. After the patient's hemodynamics returned to baseline, TAC-IV was restarted. However, his sBP rapidly decreased to 40 mmHg and the patient developed wheezing. He was diagnosed with drug-induced anaphylaxis due to castor oil derivatives in the TAC-IV formulation. The patient's sBP was restored with the administration of some vasopressors, and kidney transplantation was then performed without difficulty. Two days after kidney transplantation, oral TAC was administered without anaphylaxis. Clinicians should consider that not only the drug itself but also its additives or metabolites could induce anaphylaxis.

BACKGROUND: Recent studies have indicated that a high-fat diet (HFD) and/or HFD-induced obesity may influence prostate cancer (PCa) progression, but the role of HFD in PCa microenvironment is unclear. This study aimed to delineate the molecular mechanisms of PCa progression under HFD milieus and define the stromal microenvironment focusing on macrophage inhibitory cytokine-1 (MIC-1) activation. METHODS: We investigated the effects of HFD on PCa stromal microenvironment and MIC-1 signaling activation using PC-3M-luc-C6 PCa model mice fed with HFD or control diet. Further, we explored the effect of periprostatic adipocytes derived from primary PCa patients on activation and cytokine secretion of prostate stromal fibroblasts. Expression patterns and roles of MIC-1 signaling on human PCa stroma activation and progression were also investigated. RESULTS: HFD stimulated PCa cell growth and invasion as a result of upregulated MIC-1 signaling and subsequently increased the secretion of interleukin (IL)-8 and IL-6 from prostate stromal fibroblasts in PC-3M-luc-C6 PCa mouse model. In addition, periprostatic adipocytes directly stimulated MIC-1 production from PC-3 cells and IL-8 secretion in prostate stromal fibroblasts through the upregulation of adipose lipolysis and free fatty acid release. The increased serum MIC-1 was significantly correlated with human PCa stroma activation, high serum IL-8, IL-6, and lipase activity, advanced PCa progression, and high body mass index of the patients. Glial-derived neurotrophic factor receptor α-like (GFRAL), a specific receptor of MIC-1, was highly expressed in both cytoplasm and membrane of PCa cells and surrounding stromal fibroblasts, and the expression level was decreased by androgen deprivation therapy and chemotherapy. CONCLUSION: HFD-mediated activation of the PCa stromal microenvironment through metabolically upregulated MIC-1 signaling by increased available free fatty acids may be a critical mechanism of HFD and/or obesity-induced PCa progression.
