Survival outcomes of younger men (< 55 years) undergoing radical prostatectomy

Background: The aim of the paper is to investigate the outcomes of patients younger than 55 years in Victoria, Australia undergoing radical prostatectomy (RP) for prostate cancer. Materials and methods: Data on all men undergoing RP in Victoria between January 1, 2004 and December 31, 2014 were obtained from the Victorian Cancer Registry. Tumor characteristics including Gleason grade, stage of disease (based on final pathology specimen), and cause of death were also obtained. Statistical analysis was performed using Chi-square test, Cox proportional hazards method, and Kaplan-Meier analysis. Results: A total of 14,686 men underwent RP during the defined period. Of these men 109 were aged 35–44 years and 1,998 were aged 45–54 years. Men aged 35–44 years and 45–54 years were compared against men aged 55–74 years. The majority of men between the ages of 35 years and 44 years, and 45 years and 54 years had higher rates of Gleason ≤ 7 disease compared with men aged between 55 years and 74 years (92.7% vs. 86.8% vs. 79.3%; P < 0.01) and ≤ T2 disease (82.6% vs. 75.6% vs. 49.9%; P < 0.01) but similar median prostate-specific antigen values. On a multivariate analysis adjusting for Gleason score, T stage, and prostate-specific antigen, men aged 45–54 years and 55–64 years had 67% and 46% increase in overall survival, respectively, compared to men aged 65–74 years; but these differences were not seen in the 35–44 year age group. There were no differences in prostate cancer specific deaths between the groups. The 5- and 10-year overall survival outcomes were both higher for men aged 45–54 years compared to mean aged 55–74 years (97.9% vs. 95.9% and 94.9% vs. 85.3). Conclusion: Men aged 45–54 years undergoing RP had better overall survival compared to men aged 55–74 years, but these effects were not seen in men aged 35–44 years. There were no differences in prostate cancer specific survival in these groups

Patients with newly diagnosed invasive urothelial carcinomas of bladder (UCB) upper tract (UTUC) may experience delays to definitive radical cystectomy (RC) or radical nephro-ureterectomy (RNU) respectively. We evaluate the impact of delaying definitive surgery on survival outcomes for invasive UCB and UTUC. Methods: We searched for all studies investigating delayed urologic cancer surgery in Medline and Embase up to June 2020. A systematic review and meta-analysis was performed. Results: We identified a total of 30 studies with 32,591 patients. Across 13 studies (n = 12,201), a delay from diagnosis of bladder cancer/TURBT to RC was associated with poorer overall survival (HR 1.25, 95% CI: 1.09–1.45, p = 0.002). For patients who underwent neoadjuvant chemotherapy before RC, across the 5 studies (n = 4,316 patients), a delay between neoadjuvant chemotherapy and radical cystectomy was not found to be significantly associated with overall survival (pooled HR 1.37, 95% CI: 0.96–1.94, p = 0.08). For UTUC, 6 studies (n = 4,629) found that delay between diagnosis of UTUC to RNU was associated with poorer overall survival (pooled HR 1.55, 95% CI: 1.19–2.02, p = 0.001) and cancer-specific survival (pooled HR of 2.56, 95% CI: 1.50–4.37, p = 0.001). Limitations included between-study heterogeneity, particularly in the definitions of delay cut-off periods between diagnosis to surgery. Conclusions: A delay from diagnosis of UCB or UTUC to definitive RC or RNU was associated with poorer survival outcomes. This was not the case for patients who received neoadjuvant chemotherapy.Peer reviewe

The IDENTIFY study: the investigation and detection of urological neoplasia in patients referred with suspected urinary tract cancer - a multicentre observational study

Objective To evaluate the contemporary prevalence of urinary tract cancer (bladder cancer, upper tract urothelial cancer [UTUC] and renal cancer) in patients referred to secondary care with haematuria, adjusted for established patient risk markers and geographical variation. Patients and Methods This was an international multicentre prospective observational study. We included patients aged ≥16 years, referred to secondary care with suspected urinary tract cancer. Patients with a known or previous urological malignancy were excluded. We estimated the prevalence of bladder cancer, UTUC, renal cancer and prostate cancer; stratified by age, type of haematuria, sex, and smoking. We used a multivariable mixed-effects logistic regression to adjust cancer prevalence for age, type of haematuria, sex, smoking, hospitals, and countries. Results Of the 11 059 patients assessed for eligibility, 10 896 were included from 110 hospitals across 26 countries. The overall adjusted cancer prevalence (n = 2257) was 28.2% (95% confidence interval [CI] 22.3–34.1), bladder cancer (n = 1951) 24.7% (95% CI 19.1–30.2), UTUC (n = 128) 1.14% (95% CI 0.77–1.52), renal cancer (n = 107) 1.05% (95% CI 0.80–1.29), and prostate cancer (n = 124) 1.75% (95% CI 1.32–2.18). The odds ratios for patient risk markers in the model for all cancers were: age 1.04 (95% CI 1.03–1.05; P < 0.001), visible haematuria 3.47 (95% CI 2.90–4.15; P < 0.001), male sex 1.30 (95% CI 1.14–1.50; P < 0.001), and smoking 2.70 (95% CI 2.30–3.18; P < 0.001). Conclusions A better understanding of cancer prevalence across an international population is required to inform clinical guidelines. We are the first to report urinary tract cancer prevalence across an international population in patients referred to secondary care, adjusted for patient risk markers and geographical variation. Bladder cancer was the most prevalent disease. Visible haematuria was the strongest predictor for urinary tract cancer

Prognostic factors in urological malignancies

© 2014 Dr. Shomik SenguptaBACKGROUND: The management of urologic cancers relies heavily on the implicit or explicit application of prognostic models. This may range from the appropriate selection of diagnostic tests based upon the pre-test probability of a positive finding, to an informed decision on choice of treatment modality or enrolment in suitable clinical trials. While some prognostic factors such as stage and grade are time-tested, others such as molecular and immunohistochemical markers or surgical approach are new and evolving. Furthermore, the literature abounds with nomograms, models, risk tables or groups which utilize varying combinations of predictor variables to prognosticate on myriad outcomes of interest. The aim of this body of work was to enhance our understanding of prognostication in urologic malignancies, particularly prostate cancer, renal cancer and urothelial cancer of the bladder, in various clinical settings. METHODS: Details of methodology vary – specifics are outlined in the relevant chapters. In general terms, an appropriate study population was defined based upon the hypothesis. Variables of interest were extracted from suitable database and / or clinical records, or assessed in the laboratory. Associations between predictors and outcomes were analysed using univariate and (where suitable) multivariate regression techniques. PRINCIPAL RESULTS: • PSA kinetics provide important prognostic information in various clinical settings, including prior to surgical treatment and after hormonal therapy • A persistently detectable PSA following radical prostatectomy is associated with a greater risk of progression and death, but with a long natural history • Younger patients with prostate cancer have less aggressive features, but a proportionately greater risk of progression and death despite curative surgical treatment • Obese patients with prostate cancer have more adverse pathologic features, but similar oncological outcomes compared to those of normal weight • A positive family history is associated with an increased risk of developing prostate cancer, but similar oncologic outcomes following surgical treatment • Gleason scoring has evolved over time, with consequent changes in the prognostic implications thereof • So-called “insignificant” prostate cancer has similar oncological outcomes to low-risk cancers overall, following surgical treatment • Patient suitability for brachytherapy as a single modality can be judged based on the clinically assessed risk of lymph node or seminal vesicle involvement • Clinical factors can predict the risk of nodal metastasis, thus allowing the rational selection of patients for pelvic lymphadenectomy at the time of radical prostatectomy • RALRP is associated with a lower rate of +SM compared to ORP, even after adjusting for known clinical and pathological risk factors • Renal cancers in solitary kidneys associated with vena caval extension may be treated by nephron-sparing surgery where technically suitable, although a high risk of disease progression and death remains • The pre-operative erythrocyte sedimentation rate provides independent prognostic information in patients with renal cancer • Renal lesions with low nephrometry score as measured using the R.E.N.A.L. have a greater likelihood of having benign or indolent histology • Histologic coagulative tumour necrosis within renal cancers is associated with poorer oncological outcomes after surgical treatment • Expression of the oncogene c-kit is rare within high-grade or sarcomatoid renal cancers • Muscle invasive urothelial cancers of the bladder are often infiltrated by profuse numbers of lymphocytes with a variety of phenotypes, although they appear not to impact on the risk of progression or death after surgical treatment • Peri-operative chemotherapy has been increasing in its use over recent years, and appears to reduce the risk of recurrence after surgical treatment of urothelial cancer of the bladder CONCLUSIONS: Many of the findings summarized above have had important implications for practice. For instance: • PSA kinetics are now in widespread use at various stages of prostate cancer management • Gleason scores from patients treated some time ago are often re-interpreted according to revised criteri

Malakoplakia of the Gallbladder

Malakoplakia, a rare inflammatory condition usually occurring in the urinary tract, may occasionally be seen in other viscera, including the gall bladder. We describe one of the few cases of malakoplakia in the gall bladder, wherein, due to diagnostic confusion with carcinoma as well as operative difficulty, open cholecystectomy was necessitated. Malakoplakia of the gall bladder may be seen rarely, and then only incidentally, but needs to be kept in mind as a potential differential diagnosis for carcinoma and granulomatous cholecystitis

“Mirror” ureteric colic caused by proximal ureteric calculus in massively hydronephrotic kidney

Patients with ureteric calculi usually present with ipsilateral “loin to groin” pain. Rarely ureteric colic may present with contralateral pain, which is referred to as “mirror pain”. We report the case notes of a rare presentation of contralateral ureteric colic or “mirror pain” secondary to a ureteric calculus. A comprehensive literature review was also conducted.“Mirror pain” or contralateral ureteric colic is rare. Urologists should be aware of this unusual clinical presentation and appreciate that upper urinary tract calculi can cause pain on the contralateral side
