The clinical recurrence-free survival rates were compared to the combined clinical and biochemical recurrence-free survival rates in 285 patients with stages A2 (T1b), B (T2) and C (T3) prostate cancer treated with radiation therapy. For stages A2 (T1b) and B (T2) disease the 10-year clinical recurrence-free survival rate was 48% and the corresponding 10-year clinical and biochemical recurrence-free survival rate was 33%. For stage C (T3) disease these rates were 33% and 22%, respectively. These results demonstrate that approximately a third of the patients who are considered recurrence-free by standard clinical criteria at 10 years after radiation therapy have elevated prostate specific antigen values and are at significant risk for later clinical failure.

Objectives: This study was conducted to investigate whether preoperative or postoperative carcinoembryonic antigen (CEA) with a new cut-off value is more optimal for predicting long-term outcomes in patients with Stage II/III rectal cancer, and to investigate the effectiveness of postoperative adjuvant chemotherapy (POAC) based on the CEA values.
Methods: Serum CEA levels were measured preoperatively (pre-CEA) and postoperatively (post-CEA). The area under the receiver operating curve (AUROC) was used to determine a cut-off for CEA.

Introduction: Colorectal cancer (CRC) is a leading cause of cancer-related mortality globally. Although tumor immunotherapy is widely recognized for treating unresectable CRC, challenges such as ineffective immunotherapy and drug resistance remain prevalent. While intratumor microbiome-derived butyrate has been implicated in promoting lung cancer metastasis, its role in CRC chemoresistance is not well understood.

The present study aimed to compare the long-term survival outcomes of hepatic resection (HR) and radiofrequency ablation (RFA) in patients with single small (≤2 cm) hepatocellular carcinoma (HCC). This retrospective study enrolled patients with a single small HCC measuring 2 cm or smaller underwent HR or RFA as their initial treatment. Overall survival (OS) was significantly higher in the HR group than in the RFA group, while no significant difference was observed in recurrence free survival (RFS) between the two groups.

Breast cancer, with its high incidence and mortality globally, necessitates early prediction of local and distant recurrence to improve treatment outcomes. This study develops and validates predictive models for breast cancer recurrence and metastasis using Recurrence-Free Survival Analysis and machine learning techniques. We merged datasets from the Molecular Taxonomy of Breast Cancer International Consortium, Memorial Sloan Kettering Cancer Center, Duke University, and the SEER program, creating a comprehensive dataset of 272, 252 rows and 23 columns.

It is unknown whether this applies to patients with low-risk disease following simple hysterectomy.
Methods: Among patients who underwent simple hysterectomy in the Simple Hysterectomy And PElvic node assessment trial, univariate and multivariate Cox models were used to assess the association of minimally invasive versus open surgery with clinical outcomes, including pelvic and extra-pelvic recurrence-free survival, overall recurrence-free survival, and overall survival.
