The findings of evaluation of complex organ-sparing therapy of 153 patients with invasive bladder cancer are discussed. Transurethral resection of the exophytic end of tumor was followed by two courses of polychemotherapy plus combined treatment. Radiotherapy was carried out by conventional fractionation (group I), hyperfractionation (group II) and accelerated hyperfractionation (group III) (total focal dose--up to 60-66 Gy). Overall and corrected 5-year survival rates were: 47.3 +/- 7.5% and 51.7 +/- 7.5% (group I), 65.6 +/- 1% and 70.4 +/- 8.4% (group II), 53.9% +/- 6.8% and 61.9% +/- 6.8% (group III), respectively. Our tentative results suggest that further efforts be made to improve the efficiency of radiotherapy by introduction of novel techniques.

Radical surgery for rectal cancer with bulky lateral pelvic lymph node (LPLN) metastasis involving the sciatic nerve presents both technical and oncological challenges. Preoperative multidisciplinary treatments have recently been anticipated to control the disease as well as to preserve organ function. A 51-year-old man, presenting with right buttock pain and impairment of walking, was diagnosed with sciatic nerve impairment due to right LPLN metastasis from rectal cancer.

Aim: The aim of this study was to introduce the Esophagus-Sparing Anastomotic Narrowing Revision (ESANR) technique for the intraoperative management of anastomotic narrowing and to conduct a literature review to provide an algorithm for the management of narrowing and strictures that may develop secondary to esophagojejunostomy.
Methods: Three patients with anastomotic narrowing during esophagojejunostomy were analyzed between September 2019 and June 2024. The anastomotic narrowing was detected by intraoperative gastroscopy after reconstruction.

Background: Despite constant improvements, incontinence is one of the most relevant and quality-of-life-reducing side effects of radical prostatectomy (RP) and, in addition to patient-specific factors such as age, the experience of the surgeon/center and the surgical technique used play an important role.
Aims: To present current real-world data on short-term incontinence after RP from one of the largest German rehabilitation centers in 2022 and to compare it to the results from the same institution in 2016.
Methods And Results: Retrospective, unicentric, univariate analysis of data from 1394 men after RP in 2022 on admission and discharge from the rehabilitation clinic.

Purpose: Automated treatment plan generation is essential for magnetic resonance imaging (MRI)-guided adaptive radiotherapy (MRIgART) to ensure standardized treatment-plan quality. We proposed a novel cross-technique transfer learning (CTTL)-based strategy for online MRIgART autoplanning.
Method: We retrospectively analyzed the data from 210 rectal cancer patients.
