Understanding the impact of lymphovascular invasion on overall survival in RCC patients is crucial for surgical decision-making and postoperative care.

From November 15, 2015, to March 9, 2021, scientists conducted an open-label, phase 3 randomized clinical trial at 17 Spanish centers to assess the efficacy and safety of intraoperative HIPEC in patients with locally advanced colon cancer. The primary outcome was the 3-year locoregional control (LC) rate, which was defined as the proportion of patients who did not have peritoneal disease recurrence after adjusting for intention to treat. Patients included ranged in age from 18 to 75 years old and had been diagnosed with locally advanced primary colon cancer prior to surgery. They discovered that combining HIPEC with complete surgical resection for locally advanced colon cancer enhanced the 3-year LC rate compared to surgery alone, and they recommend that this strategy be evaluated for patients with locally advanced colorectal cancer.

Data on patients with mismatch repair deficiency (MMRD) CRC, the majority of whom could not undergo surgery due to various health conditions unrelated to cancer, were presented at the 2023 American Society of Clinical Oncology Gastrointestinal Cancers Symposium (ASCO GI). Instead of radiation therapy or chemotherapy, the patients received immunotherapy with checkpoint inhibitors. It should be noted that the patients were treated outside of clinical trials. The overall response rate in this patient group was 74%, with 57% of those who responded experiencing complete tumor regression. Some of the patients have been in complete remission for a year or more after their diagnoses. The data indicate that immunotherapy is an effective treatment for patients who are unable to undergo surgery for a variety of reasons, including advanced age or a variety of health issues.

The purpose of this study was to assess the relationship between the RTOG clinical target volumes (CTVs) and PSMA PET-defined recurrence topography, as well as to analyze the patterns of prostate bed (PB) recurrence in prostate cancer patients who had PSA persistence (BCP) or biochemical recurrence (BCR) following radical prostatectomy.

In this multi-institutional study, AT significantly increased progression-free and overall survival in 430 patients with node-negative (N0) disease after NAT for localized pancreatic cancer (4.1 vs 2.1 and 5.3 vs 3.5 years, respectively). Patients who received neoadjuvant radiation had their overall survival benefit scaled back, while patients with perineural invasion saw an increase.

In this randomized trial from Poland, Norway, Sweden, and the Netherlands, the study population of approximately 85,000 individuals were randomly assigned to colonoscopy screening or usual care. The risk of colorectal cancer at 10 years was 18% lower in the screening cohort.
