We assessed the outcomes of high-risk prostate cancer patients who received radical prostatectomy (RP), external beamradiation therapy (EBRT) or androgen deprivation therapy (ADT). Two hundred nineteen patients who were diagnosed with pathologically confirmed high-risk prostate cancer as defined by D'Amico between 2005 and 2011 were included in this study. Of them, 74 patients underwent RP. The 5-year cancer-specific survival (5yCSS) and 5-year PSA recurrence-free survival (5yPRFS) rates were 100 and 67.2%, respectively. A positive surgical margin and Gleason score≧8 were risk factors for PSA recurrence. The 5yPRFSs were 100, 74.4% and 'unmeasurable' for patients with 0, 1 and 2 risk factors, respectively. Ninety patients underwent EBRT. The 5yCSS and 5yPRFS rates were 95.2 and 74.2%, respectively. Fifty-five patients underwent ADT alone. Their 5yCSS and 5yPRFS rates were 93. 3 and 64. 3%, respectively. There was no significant difference in 5yCSS and 5yPRFS rates among the treatment groups. These results show that RP can be a treatment option for high-risk prostate cancer patients.

Individuals with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) have a high risk of developing other malignancies (OMs). The development of OMs may be associated with the advanced age of CLL/SLL patients, presence of a tumor-promoting microenvironment, immune alterations inherent to CLL/SLL, or chemotherapy. Importantly, the occurrence of OMs following frontline fludarabine, cyclophosphamide and rituximab (FCR) treatment is associated with a reduction in the overall survival (OS).

Background: To determine outcomes of MRI-assisted radiosurgery (MARS) for salvage brachytherapy using the radioisotope Pd after various upfront treatments including surgery, external beam radiotherapy, and brachytherapy.
Methods: We retrospectively reviewed data for patients who underwent salvage MARS for intraprostatic lesions or prostate bed recurrences from 2016 to 2022. Biochemical recurrence, prostate cancer-specific, and overall survival, and the cumulative incidences of toxicities, were determined by Kaplan-Meier estimates.
Pelvic regional control with 25Gy in 5 fractions in SBRT for high risk prostate cancer: Pooled prospective outcomes from the SHARP consortium.

Aim: To evaluate the efficacy of 25Gy/5# prophylactic pelvic nodal irradiation for regional control during stereotactic radiotherapy (SBRT) for high risk prostate cancer.
Methods: The multinational XXXX consortium database of patients treated with curative-intent prostate SBRT for high risk prostate cancer was queried for prophylactic radiotherapy 25Gy/5# to the pelvic lymph nodes. Details of Phoenix-defined biochemical failure, and location of recurrence (local, regional, or distant) were extracted.
Randomized controlled trials (RCTs) evaluating anti-cancer agents often lack generalizability to real-world oncology patients. Although restrictive eligibility criteria contribute to this issue, the role of selection bias related to prognostic risk remains unclear. In this study, we developed TrialTranslator, a framework designed to systematically evaluate the generalizability of RCTs for oncology therapies.

Rationale And Objectives: To develop an automatic deep-radiomics framework that diagnoses and stratifies prostate cancer in patients with prostate-specific antigen (PSA) levels between 4 and 10 ng/mL.
Materials And Methods: A total of 1124 patients with histological results and PSA levels between 4 and 10 ng/mL were enrolled from one public dataset and two local institutions. An nnUNet was trained for prostate masks, and a feature extraction module identified suspicious lesion masks.
