Feasibility and delivery of patient-reported outcomes in clinical practice among racially diverse bladder and prostate cancer patients

ObjectiveTo assess the feasibility of enrollment and collecting patient-reported outcome (PRO) data as part of routine clinical urologic care for bladder and prostate cancer patients and examine overall patterns and racial variations in PRO use and symptom reports over time.Subjects/Patients and MethodsWe recruited 76 patients (n = 29 Black and n = 47 White) with prostate or bladder cancer at a single, comprehensive cancer center. The majority of prostate cancer patients had intermediate risk (57%) disease and underwent either radiation or prostatectomy. Over half (58%) of bladder cancer patients had muscle invasive disease and underwent cystectomy.Patients were asked to complete PRO symptom surveys using their preferred mode [web- or phone-based interactive voice response (IVR)]. Symptom summary reports were shared with providers during visits. Surveys were completed at 3 time points and assessed urinary, sexual, gastrointestinal, anxiety/depression, and sleep symptoms. Feasibility of enrollment and survey completion were calculated, and linear mixed effects models estimated differences in outcomes by race and time.ResultsSixty three percent of study participants completed all PRO measures at all 3 time points. Black patients were more likely to select IVR as their survey mode (40% vs. 13%, P < 0.05), and less likely to complete all surveys (55% vs. 74%, P = 0.13). Patients using IVR were also less likely to complete all surveys (41% vs. 69%, P = 0.046).ConclusionsReported preferences for survey mode and completion rates differ by race, which may influence survey completion rates and highlight potential obstacles for equitable implementation of PROs into clinical care.     

A national cross-sectional survey of financial toxicity among bladder cancer patients

ObjectiveFinancial toxicity (FT) has been defined as the patient-level impact of the costs of cancer care. Our objective was to better characterize FT among bladder cancer patients as well as oncologic, demographic and insurance characteristics related to FT.MethodsWe conducted a cross-sectional survey of the Bladder Cancer Advocacy Network Patient Survey Network using the validated COST (COmprehensive Score for financial Toxicity) questionnaire. Our primary outcome was relative degree of FT, with lower COST scores corresponding to worse FT. Wilcoxon rank sum tests and multiple regression were used to evaluate differences in demographic, diagnostic and treatment characteristics as they related to degree of FT.ResultsAmong 226 patients, median age was 68 years with 64% male, 83% married, and 49% with Medicare with supplemental insurance. Respondents reported an average of 65 months since diagnosis, with 62% reporting noninvasive disease. Mean COST was 28.4 (range 0–44). On multivariable analysis, patients who were younger, with a household annual income less than $50,000, not retired, or with insurance that was neither Medicare nor employer paid were significantly more likely to have worse FT. A majority of respondents (63.5%) agreed or strongly agreed that they would be interested in discussing cost in the context of their treatment preferences, independent of COST score (P = 0.24).ConclusionsA national cross-sectional survey demonstrated high prevalence of FT which was worse among younger patients with lower incomes, not retired, and without employer-paid or Medicare insurance. Most patients preferred to discuss treatment costs with their bladder cancer provider.     

Visceral and subcutaneous adipose tissue,which one induced thyroid dysfunction in patients with morbid obesity

BackgroundThyroid dysfunction in patients with morbid obesity usually resolves after bariatric surgery. However, the role of diverse types of adipose tissue in the process remains unknown.ObjectivesWe aim to investigate the effects of visceral and subcutaneous fat on thyroid function in a Chinese population with morbid obesity who underwent sleeve gastrectomy (SG).SettingUniversity hospital, Shanghai, ChinaMethodsRepeated measurement data of thyroid hormone and body fat were collected at 0, 3, 6, 12, 24, and 36 months after sleeve gastrectomy. Dual-energy X-ray absorptiometer and quantitative computerized tomography (CT) were used to compute visceral fat and subcutaneous fat. Repeated measures correlation (rmmcorr) package was employed for correlation analysis with generalized additive mixed model (GAMM) determining the independent factors.ResultsThyroid stimulating-hormone (TSH) showed notable decrease at 36 months after surgery, coupled with reduction of BMI (38.08 kg/cm² versus 24.28 kg/cm²), C-reactive protein (CRP), visceral adipose tissue (786.74 cm² versus 367.44 cm²), body fat rate, and waistline (118.13 cm versus 100.87 cm). Only visceral fat, diabetes, and CRP proved to be independent variables for TSH decline, without correlation with subcutaneous fat.ConclusionThe present study is first to report the effects of different types of body fat on thyroid function in a Chinese population with morbid obesity, revealing that loss of visceral fat is the key to improving endocrine and metabolic activity after bariatric surgery.     

腹腔镜食管胃吻合肌瓣成形术对于直径>5 cm食管胃结合部肿瘤近端胃切除术后消化道重建安全可行

目的探讨腹腔镜辅助食管胃吻合肌瓣成形术(Kamikawa吻合)在治疗肿瘤最大径>5 cm的食管胃结合部(EGJ)平滑肌瘤或胃肠间质瘤近端胃切除术后消化道重建的安全性及可行性。方法采用描述性病例系列研究方法,回顾性分析广东省中医院胃肠外科2017年9月至2019年3月期间,收治并施行腹腔镜辅助近端胃切除术和Kamikawa吻合的EGJ平滑肌瘤和胃肠间质瘤病例资料。肿瘤均侵犯贲门齿状线,且最大径>5 cm;排除需急诊手术和合并有严重心肺疾病患者后,共4例患者纳入本研究,男性3例,女性1例,年龄29-49岁。患者接受腹腔镜辅助近端胃切除术后,把残胃提出腹腔外,距残胃前壁近端3-4 cm处亚甲蓝标记"H"形,并沿"H"形切开胃壁浆肌层,沿纵行切开线向两侧分离黏膜下层和肌层之间的间隙,制作浆肌瓣;将残胃放回腹腔,腹腔镜下将"H"形上边与食管后壁距断端4-5 cm处间断缝合4针;切开食管残端,在"H"形的下边切开黏膜下层和黏膜层,进入胃腔;腹腔镜下将食管断端后壁与残胃黏膜层和黏膜下层连续缝合,食管断端前壁与残胃全层连续缝合,将胃前壁浆肌瓣缝合包埋食管,完成消化道重建。观察患者术中并发症和术后反流性食管炎和吻合口相关并发症的发生率。结果 4例患者均顺利完成手术,无中转开腹。手术中位时间为239(192-261)min,Kamikawa吻合中位时间为149(102-163)min,术中中位出血量为35(20-200)ml。4例患者均术后第1天拔除腹腔引流管和胃管,并恢复流质饮食,术后住院中位时间为6(6-8)d。术后病理提示,3例平滑肌瘤,1例胃肠间质瘤。术后无吻合口漏及狭窄等并发症,未观察到反流症状。术后中位随访时间22(11-29)个月,4例患者复查胃镜均未见反流性食管炎。结论对于>5 cm的EGJ平滑肌瘤或胃肠间质瘤,近端胃切除术后应用腹腔镜辅助Kamikawa吻合进行消化道重建,安全可行。     

Does the type of cryoprobe affect oncological and functional outcomes in men with clinically localized prostate cancer treated with primary whole gland prostate cryoablation?

Background:This study aimed to compare the oncological and functional outcomes of primary whole gland cryoablation of the prostate using the variable ice cryoprobe (V-Probe^®) and the conventional fixed-size ice probe.Materials and methods:We reviewed the Cryo On-Line Data Registry for men who were treated with primary whole gland prostate cryoablation from 2000 through 2017. A multivariate Cox proportional hazards model was used to compare timing to biochemical recurrence between the V-Probe^® and fixed-size ice probe after adjusting for preoperative prostate-specific antigen (PSA), neoadjuvant androgen deprivation therapy, preoperative Gleason score, and preoperative T stage.Results:A total of 1124 men were included. Median age, Gleason score, and pretreatment PSA were 70 years (interquartile range [IQR]: 65–74 years), 7 (IQR: 6–7) and 5.9 ng/mL (IQR: 4.6–8.1 ng/mL), respectively. The median follow-up time was 25.0 months (IQR: 11.2–48.6 months). V-Probes^® were used in 269 (23.9%) cases and fixed-size ice probes in 858 (76.1%) cases. After adjusting for clinical T stage, PSA, neoadjuvant androgen deprivation therapy and preoperative Gleason score, on the multivariate Cox regression model, we found that there was no significant difference between the type of probe and timing to biochemical recurrence (p = 0.35). On multivariate logistic regression, using the V-Probe^® was associated with a 91% increase in postoperative urinary retention compared to the fixed-size ice probe (p = 0.003).Conclusions:The use of the V-Probe^® versus conventional fixed-size ice probe was not associated with a difference in biochemical recurrence in patients undergoing primary cryoablation of the prostate.
