- Background:The delay between onset of macroscopic haematuria and diagnosis of bladder cancer is often long.Methods:We evaluated timely diagnosis and health-care costs for patients with macroscopic haematuria given fast-track access to diagnostics. During a 15-month period, a telephone hotline for fast-track diagnostics was provided in nine Swedish municipalities for patients aged ⩾50 years with macroscopic haematuria. The control group comprised 101 patients diagnosed with bladder cancer in the same catchment area with macroscopic haematuria who underwent regular diagnostic process.Results:In all 275 patients who called ‘the Red Phone’ hotline were investigated, and 47 of them (17%) were diagnosed with cancer and 36 of those had bladder cancer. Median time from patient-reported haematuria to diagnosis was 29 (interquartile range (IQR) 14−104) days and 50 (IQR 27−165) days in the intervention and the control group, respectively (P=0.03). The median health-care costs were lower in the intervention group (655 (IQR 655−655) EUR) than in the control group (767 (IQR 490−1096) EUR) (P=0.002).Conclusions:Direct access to urologic expertise and fast-track diagnostics is motivated for patients with macroscopic haematuria to reduce diagnostic intervals and lower health-care expenditures.British Journal of Cancer advance online publication, 25 August 2016; doi:10.1038/bjc.2016.265 www.bjcancer.com.

- Objective: This study assessed a national healthcare intervention launched in Sweden in 2015 to reduce the time between macroscopic haematuria, diagnosis and treatment of urinary tract cancer. Methods: The outcome of the first 11 months was evaluated in 1697 individuals referred to a standardized care pathway for urinary tract cancer compared with 174 patients with conventionally diagnosed urothelial carcinoma. Results: Among the referred individuals, 317 (19%) were diagnosed with cancer, 1034 (61%) had a benign diagnosis and 345 (20%) had a negative evaluation. Bladder cancer was the most common malignant diagnosis [262/317 (83%)]. Cancers were diagnosed in 23% of males and 13% of females, and showed a strong correlation with age: cancer diagnosis in 2% aged <50 years and in 44% aged ≥90 years. Results were affected by bacteriuria but not by anticoagulant medication, with 12%/22% and 19%/19% cancer detection, respectively. The standardized care pathway shortened the diagnostic delay to a median of 25 days compared to 35 days for regular referral (p =.01). However, median time to treatment was unchanged: 39 days from referral to transurethral resection, 42 days from primary resection to re-resection for stage TaG3/T1 disease and 100 days from referral to curative treatment for muscle-invasive disease. Conclusions: Macroscopic haematuria had a cancer capture rate of 19%, with higher predictive values in men and at older age, whereas anticoagulant therapy did not influence the diagnostic yield. The demonstrated lack of effect on time to treatment underscores the need to consider the entire patient process when initiating healthcare reforms to improve outcome.

- Lynch syndrome confers an increased risk for urothelial carcinoma (UC). Molecular subtypes may be relevant to prognosis and therapeutic possibilities, but have to date not been defined in Lynch syndrome-associated urothelial cancer. We aimed to provide a molecular description of Lynch syndrome-associated UC. Thus, Lynch syndrome-associated UCs of the upper urinary tract and the urinary bladder were identified in the Danish hereditary nonpolyposis colorectal cancer (HNPCC) register and were transcriptionally and immunohistochemically profiled and further related to data from 307 sporadic urothelial carcinomas. Whole-genome mRNA expression profiles of 41 tumors and immunohistochemical stainings against FGFR3, KRT5, CCNB1, RB1, and CDKN2A (p16) of 37 tumors from patients with Lynch syndrome were generated. Pathological data, microsatellite instability, anatomic location, and overall survival data were analyzed and compared with sporadic bladder cancer. The 41 Lynch syndrome-associated UC developed at a mean age of 61 years with 59% women. mRNA expression profiling and immunostaining classified the majority of the Lynch syndrome-associated UC as urothelial-like tumors with only 20% being genomically unstable, basal/SCC-like, or other subtypes. The subtypes were associated with stage, grade, and microsatellite instability. Comparison to larger datasets revealed that Lynch syndrome-associated UC shares molecular similarities with sporadic UC. In conclusion, transcriptomic and immunohistochemical profiling identifies a predominance of the urothelial-like molecular subtype in Lynch syndrome and reveals that the molecular subtypes of sporadic bladder cancer are relevant also within this hereditary, mismatch-repair defective subset.
