Purpose: Prediction of extracapsular extension (ECE) before radical prostatectomy in clinically localized prostate cancer (PCa) is very important for clinical practice. ECE affects our decision on treatment strategy. The aim of this study is to identify the predictors of ECE, determine cut-off values, and compare them with the accuracy of Partin Table parameters to improve tumor staging in clinical practice.
Materials And Methods: 374 patients with clinically localized PCa who underwent open radical retropubic prostatectomy (RRP) were included in this study. Gleason Score (GS), age, digital rectal examination (DRE), prostate specific antigen (PSA), prostate specific antigen density (PSAD), free PSA, Free/Total PSA, prostate volume (PV), number of cores involved, tumor length, and tumor percentage in maximum involved core in biopsy were investigated.
Results: PSAD, tumor percentage, and tumor length are predictive factors of ECE. The cut-off values of PSA, PSAD, maximum tumor length, and maximum tumor percentages in predicting ECE are: > 8.90 ng/mL, > 0.26 ng/mL2, >5mm, and >50%, respectively. The cut-off values for Partin extraprostatic extension (EPE) and organ confined (OC) disease are >29% and ≤ 64%, respectively.
Conclusion: Partin tables could better predict extracapsular extension in clinically localized PCa if they include PSAD, tumor percentage, and tumor length. The cut-off values of these predictive factors can be beneficial in treatment strategies and in the decisions of lymphadenectomy and nerve-sparing surgery at radical prostatectomy.

Background: Pulmonary sarcomatoid carcinoma (PSC) is a rare lung cancer characterized by early metastasis and invasion. It is predominantly diagnosed at a locally advanced or metastatic stage, hindering the possibility of surgical intervention. However, a standard treatment for advanced PSC remains unestablished.

Background: Endoscopic submucosal dissection (ESD) is a standardized procedure for intramucosal and slightly invasive submucosal colorectal cancers (CRC). However, the role of ESD for T1b (depth of submucosal invasion: ≥1,000 μm) CRC remains unclear. This study aimed to investigate the long-term efficacy and safety of ESD for T1b CRC.

Background: Dermatofibrosarcoma protuberans (DFSP) is a rare, low-grade fibrohistiocytic tumor with malignant potential. It is considered to have a high local recurrence rate due to the characteristic invasion of the finger-like lesion into the soft tissues.
Method: This retrospective study presents details of 20 DFSP patients with a history of surgery and a long follow-up period.
High-Cost Cancer Drug Use in Medicare Advantage and Traditional Medicare.
JAMA Health Forum

Department of Health Systems, Management, and Policy, University of Colorado Cancer Center, Aurora.
Importance: Medicare Advantage (MA) plans are designed to incentivize the use of less expensive drugs through capitated payments, formulary control, and preauthorizations for certain drugs. These conditions may reduce spending on high-cost therapies for conditions such as cancer, a condition that is among the most expensive to treat.
Objective: To determine whether patients insured by MA plans receive less high-cost drugs than those insured by traditional Medicare (TM).
Healthy Lifestyle Care vs Guideline-Based Care for Low Back Pain: A Randomized Clinical Trial.
JAMA Netw Open

University Centre for Rural Health, School of Health Sciences, University of Sydney, Lismore, New South Wales, Australia.
Importance: An unhealthy lifestyle is believed to increase the development and persistence of low back pain, but there is uncertainty about whether integrating support for lifestyle risks in low back pain management improves patients' outcomes.
Objective: To assess the effectiveness of the Healthy Lifestyle Program (HeLP) compared with guideline-based care for low back pain disability.
Design, Setting, And Participants: This superiority, assessor-blinded randomized clinical trial was conducted in Australia from September 8, 2017, to December 30, 2020, among 346 participants who had activity-limiting chronic low back pain and at least 1 lifestyle risk (overweight, poor diet, physical inactivity, and/or smoking), referred from hospital, general practice, and community settings.
