Summary: The study demonstrated that lincRNA-p21 expression levels are associated with response to neoadjuvant CRT in rectal cancer patients, serving as a predictive biomarker. It is also correlated with tumor stage, tumor regression grade, and other indicators.

Summary: A gene-expression based classifier was developed to identify over 1/3 of rectal cancer patients with a pathological complete response (pCR), while ensuring no non-complete-responders were misclassified. The classifier's performance was validated in three independent datasets, suggesting it could help select patients for a watch and wait strategy.

Summary: This study reveals the influence of intratumoral microbiota on the response to neoadjuvant chemoradiotherapy (nCRT) in locally advanced rectal cancer (LARC). The microbial profiles in the tumor microenvironment were found to be different between patients with a pathological complete response (pCR) and those without. The interaction between intratumoral microbes and cancer-associated fibroblasts (CAFs) plays a crucial role in mediating the response to nCRT.

Summary: This study analyzed the predictive factors, recurrence patterns, oncologic outcomes, and prognostic factors of patients with pathologic complete response (pCR) in rectal cancer who underwent radical surgery after neoadjuvant chemoradiotherapy (nCRT). The study found that clinical node negativity, tumor size < 4 cm, and well differentiation were significant independent clinical predictors for achieving pCR. Patients with pCR had better long-term outcomes compared to those without pCR.

Summary: The study aimed to identify patients' response to preoperative chemoradiotherapy (PCRT) in locally advanced rectal cancer (LARC) through miRNA expression profiling in plasma. The miRNA panel accurately predicted response to PCRT and outperformed conventional clinical factors.

Summary: This study evaluated the efficacy and toxicity of hypofractionated preoperative chemoradiotherapy (HPCRT) combined with oral capecitabine in patients with rectal cancer. The results showed that a significant number of patients achieved pathological complete response and sphincter preservation. Tumor and nodal downstaging were also observed, and the survival rates were promising. The fractionation scheme showed similar results to long-course fractionation with less toxicity, making it beneficial for certain patients.

Summary: The multiparametric MRI scoring system showed some predictive value in assessing treatment response for patients with LARC, despite the low agreement with pathological results. Combining complete response and near complete response categories improved sensitivity and positive predictive value for the readers.

Summary: This study investigated the role of T2 relaxation time in predicting pathological response to chemoradiotherapy (CRT) in locally advanced rectal cancer (LARC) patients. The results showed that T2 relaxation time could help predict treatment response to CRT for LARC earlier, alleviating the physical burden for patients with no good response.

Summary: The standard treatment approach for stage II/III rectal cancer is neoadjuvant chemoradiation therapy followed by surgery. However, better tools are still needed to personalize therapy for the individual patient. In this study, the researchers analyzed colon-derived cell-free DNA using a tissue-specific DNA methylation signature and found that it can predict treatment outcomes and help guide patient selection strategies.

Summary: Despite advancements in screening and vaccination programs, uterine cervical cancer remains a leading cause of cancer-related mortality in women worldwide. New therapeutic approaches have not significantly improved treatment response and prognosis, highlighting the urgent need for robust molecular markers to predict therapy response and clinical outcome.

Summary: This study assessed the use of CT-based fractal dimension and texture analysis in predicting the therapeutic response to nCRT in patients with locally advanced rectal cancer. The research found that fractal dimension was a significant parameter for predicting the efficacy of nCRT.
