Actor-Partner Effects of Personality Traits and Psychological Flexibility on Psychological Distress Among Couples Coping with Cancer.

In this study, we applied the actor-partner interdependence model (APIM) to explore the associations between personality traits (Big Five) and psychological flexibility, on the one hand, and depression and anxiety, on the other hand, among patients with cancer and their spouses. Method: Forty-six patient-spouse dyads (N = 92) completed the anxiety and depression scales from the Patient-Reported Outcomes Measurement Information System (PROMIS), the ten-item personality inventory (TIPI), and the psychological flexibility scale (AAQ-2). Multilevel APIM models, adjusted for multiple testing, showed that neuroticism and psychological flexibility had actor effects on patients' depression and anxiety.

Duration of immunotherapy in dMMR/MSI-H metastatic colorectal cancer patients.

Background: Immune checkpoint blockade (ICB) has revolutionized treatment of mismatch repair-deficient (dMMR)/microsatellite instability-high (MSI-H) metastatic colorectal cancer (mCRC). However, there is no evidence on the optimal treatment duration. We aimed to compare outcomes of different immunotherapy durations.

Assessment of the Addition of Oxaliplatin to Fluoropyrimidine-Based Adjuvant Chemotherapy in Patients With High-Risk Stage II Colon Cancer: An ACCENT Pooled Analysis.

Purpose: The adjuvant treatment for stage III colon cancer (CC) is chemotherapy combining fluoropyrimidine (FP) and oxaliplatin (OX). FP regimen plus OX (FPOX) may benefit in high-risk stage II CC. We performed a pooled analysis of pivotal MOSAIC and C-07 studies evaluating FPOX for the treatment of high-risk stage II CC according to prognostic factors, number of high-risk factors, and current clinicopathologic risk classification on the basis of T stage, tumor perforation, and number of lymph nodes examined.

Immune checkpoint inhibitors for POLE or POLD1 proofreading-deficient metastatic colorectal cancer.

Background: POLE and POLD1 proofreading deficiency (POLE/D1pd) define a rare subtype of ultramutated metastatic colorectal cancer (mCRC; over 100 mut/Mb). Disease-specific data about the activity and efficacy of immune checkpoint inhibitors (ICIs) in POLE/D1pd mCRC are lacking and it is unknown whether outcomes may be different from mismatch repair-deficient (dMMR)/microsatellite instability-high (MSI-H) mCRCs treated with ICIs.

Patients And Methods: In this global study, we collected 27 patients with mCRC harboring POLE/D1 mutations leading to proofreading deficiency and treated with anti-programmed cell death-ligand 1 alone +/- anti-cytotoxic T-lymphocyte antigen-4 agents.

Immunotherapy in mismatch repair-deficient metastatic colorectal cancer - Outcome and novel predictive markers.

Background: This study aims to assess predictive markers for response to immunotherapy in dMMR/MSI-H metastatic colorectal cancer (mCRC) patients.

Materials And Methods: A study using two prospective cohorts from MD Anderson Cancer Center and Sheba Medical Center of consecutive patients with dMMR/MSI-H mCRC that were treated with immunotherapy between 2014-2022. Primary outcome was progression-free survival (PFS) and secondary outcome was overall response rate (ORR).
