Comparative StudyPreoperative lymph-node staging of invasive urothelial bladder cancer with 18F-fluorodeoxyglucose positron emission tomography/computed axial tomography and magnetic resonance imaging: correlation with histopathology.
The treatment and prognosis of bladder cancer are based on the depth of primary tumour invasion and the presence of metastases. A highly accurate preoperative tumour, node, metastasis (TNM) staging is critical to proper patient management and treatment. This study retrospectively investigated the value of ¹⁸F-fluorodeoxyglucose (FDG) positron emission tomography/computed axial tomography (¹⁸F-FDG PET/CT) and magnetic resonance imaging (MRI) for preoperative N staging of bladder cancer. ⋯ No significant statistical difference between ¹⁸F-FDG PET/CT and MRI for preoperative N staging of urothelial bladder cancer was found in the study. However, the trend of the data indicates an advantage of ¹⁸F-FDG PET/CT over MRI. Larger prospective studies are needed to elucidate the role of ¹⁸F-FDG PET/CT in N staging of bladder cancer.

Randomized Controlled TrialPosterior and anterior fixation of the urethra during robotic prostatectomy improves early continence rates.
To investigate whether posterior and anterior fixation of the vesicourethral anastomosis during robotic radical prostatectomy (RRP) helps to establish continence earlier. ⋯ The posterior and anterior fixation of the vesicourethral anastomosis during RRP results in an intact sphincteric mechanism, because no stretch is applied to the urethra, resulting in earlier continence.

Validation of a new plasma cystatin C-based formula and the Modification of Diet in Renal Disease creatinine-based formula for determination of glomerular filtration rate.
New proposed definitions of chronic kidney disease necessitate the development and use of simple and accurate methods for estimating glomerular filtration rate (GFR). Plasma cystatin C has been shown to be a more reliable GFR marker than creatinine and formulae for estimating GFR have been reported. The purpose of this study was to validate a cystatin C-based GFR prediction equation in a different population from the derivation set but using the cystatin C assay of a single laboratory, and to compare the results with that of the creatinine-based Modification of Diet in Renal Disease (MDRD) Study equation. ⋯ GFR estimation based on plasma cystatin C performed equally well in the validation as in the derivation set, and was as accurate as the re-expressed MDRD creatinine-based equation.

Comparative StudyHealth-related quality of life 10 years after external beam radiotherapy or watchful waiting in patients with localized prostate cancer.
To evaluate long-term randomized comparisons of patient-reported outcome of symptoms and health-related quality of life (HRQoL) in men with localized prostate cancer 10 years after external beam radiotherapy (RT) or watchful waiting (WW). ⋯ The pattern of urinary and bowel symptoms and sexual function was rather similar, independent of RT or WW. Treatment with RT had minimal influence on HRQoL, in comparison with that of WW, at 10-year follow-up.

Long-term follow-up after triple treatment of prostate cancer stage pT3.
Radical prostatectomy (RP) has become the most common treatment for localized prostate cancer in Sweden. Outcome is extremely good for pT2 stage with Gleason score 6 or less, but more than every fourth operated patient will have a pT3 stage on full amount specimen histology. According to several reports the risk of biochemical recurrence is quite high, especially in stage pT3, on active surveillance after surgery alone. In 1994 the authors recognized this fact at their clinic and decided to apply a new multimodality treatment concept. ⋯ Patients with locally advanced prostate cancer have a high risk of progression after RP as single therapy. Postoperative RT has been shown to improve the outcome. Neoadjuvant/adjuvant hormonal therapy has been shown to improve the outcome after RT. Bringing this knowledge together offering a multimodality therapy with neoadjuvant/adjuvant hormonal therapy, RP followed by postoperative immediate RT seems to offer a high chance of biochemical-free survival.
