Quality of life and functional outcomes in patients with locally advanced rectal cancer receiving total neoadjuvant therapy versus concurrent chemoradiotherapy: An analysis of the XXX trial.

Objective: To explore differences in the effects of total neoadjuvant therapy (TNT) and preoperative concurrent chemoradiotherapy (CRT) on quality of life and functional outcomes in patients with locally advanced rectal cancer.

Methods: In the study, 591 patients with distal or middle-third, clinical primary tumor stage cT3-4 and/or regional lymph node-positive rectal cancer were randomly assigned (1:1) to receive short-term radiotherapy (25 Gy in five fractions) followed by 4 cycles of CAPOX (TNT group, n=297) or standard concurrent chemoradiotherapy (50 Gy in 25 fractions concurrently with oral capecitabine) (CRT group, n=294) before surgery. After a 6-year follow-up, the surviving patients were sent surveys, including the EORTC QLQ-C30, EORTC QLQ-CR29, and Wexner incontinence score questionnaires.

ZNF37A downregulation promotes TNFRSF6B expression and leads to therapeutic resistance to concurrent chemoradiotherapy in rectal cancer patients.

The identification a signature comprising a group of genes as markers of cancer response to chemoradiotherapy would be more appropriate and effective for predicting chemoradiotherapy efficacy. This study investigated the differentially expressed genes (DEGs) related to chemoradiotherapy resistance and established a multigene expression model for predicting the sensitivity of rectal cancer to chemoradiotherapy in rectal cancer patients, elucidated the mechanism of resistance to synchronized chemoradiotherapy. The genome-wide expression profiling microarray were performed in the tissues of 81 rectal cancer patients before neoadjuvant therapy to analyze and discover DEGs related to chemoradiotherapy resistance, and the results were verified in 45 rectal cancer patients, and finally a 20-gene signature was proposed to be a predictor of chemoradiotherapy response.

Tumor biopsies at baseline were stained for CD8+ and CD3+ T-cell densities.

Optimizing the combination of chemotherapeutic drugs along with radiotherapy for extranodal NK/T-cell lymphoma.

Background: Extranodal natural killer/T-cell lymphoma (ENKTCL) has a unique treatment principle. However, the optimal combination of drugs along with radiotherapy (RT) is unknown.

Design: Retrospective cohort study.

Estimating the long-term survival of unresectable stage III non-small cell lung cancer based on cure model analysis.

Background: The predictors of long-term survival and appropriate surrogate endpoints in unresectable stage III non-small cell lung cancer (NSCLC) treated with radiotherapy remain unclear, especially in the immune therapy era.

Methods: This study retrospectively analyzed a prospective cohort of 822 patients treated at the Chinese National Cancer Center from 2013 to 2022. Cure fractions, surrogates for long-term survival, and associated factors were assessed using a mixture cure model, with validation against a matched Surveillance, Epidemiology, and End Results (SEER) dataset.

Preoperative chemoradiotherapy in older patients with rectal cancer guided by comprehensive geriatric assessment within a multidisciplinary team-a multicenter phase II trial.

Background: The purpose of this study was to evaluate the safety and efficacy of preoperative concurrent chemoradiotherapy (preCRT) for locally advanced rectal cancer in older people who were classified as "fit" by comprehensive geriatric assessment (CGA).

Methods: A single-arm, multicenter, phase II trial was designed. Patients were eligible for this study if they were aged 70 years or above and met the standards of "fit" (SIOG1) as evaluated by CGA and of the locally advanced risk category.

Regulation of AMPK activation by extracellular matrix stiffness in pancreatic cancer.

The adenosine monophosphate (AMP)-activated protein kinase (AMPK) sits at a central node in the regulation of energy metabolism and tumor progression. AMPK is best known to sense high cellular ADP or AMP levels, which indicate the depletion of energy stores. Previous studies have shown that the low expression of phosphorylated AMPK is associated with a poor prognosis of pancreatic cancer.

Prediction of 5-year overall survival of diffuse large B-cell lymphoma on the pola-R-CHP regimen based on 2-year event-free survival and progression-free survival.

This study aimed to predict the 5-year overall survival (OS) benefit of pola-R-CHP versus R-CHOP in the POLARIX trial based on the 2-year event-free survival (EFS) and progression-free survival (PFS) rates in diffuse large B-cell lymphoma (DLBCL). We identified randomized controlled trials (RCT) published before 31 May 2023. The correlation between the logarithmic (log) hazard ratio (HR) for EFS (HR) or PFS (HR) and the HR for OS (HR) was estimated at the trial-level.

Multicenter phase II study of moderate low-dose radiotherapy in indolent non-Hodgkin lymphoma: CLCG-iNHL-01 protocol.

Radiotherapy is an effective treatment for indolent non-Hodgkin lymphoma (iNHL); however, the optimal radiotherapy dose remains to be determined. We hypothesize that a suitable dose may exist between 4 and 24 Gy. This prospective multicenter phase II trial intends to recruit 73 sites of iNHL patients, who will receive involved-site radiotherapy of 12 Gy in four fractions.
