Identification of Germline Variants in Patients with Hereditary Cancer Syndromes in Northeast Mexico.

Hereditary cancer syndromes (HCS) are genetic diseases with an increased risk of developing cancer. This research describes the implementation of a cancer prevention model, genetic counseling, and germline variants testing in an oncologic center in Mexico. A total of 315 patients received genetic counseling, genetic testing was offered, and 205 individuals were tested for HCS.

Post-traumatic Stress Symptoms, Distress, and Optimism in Mexican Colorectal Cancer Patients.

Background: The diagnosis and treatment of colorectal cancer are considered highly stressful and potentially traumatic events that can generate post-traumatic stress symptoms and distress among patients.

Objective: To evaluate LNR as a prognostic factor for disease-free survival (DFS) in patients with oral squamous cell carcinoma.

Method: Retrospective observational study.

Internet-Delivered Cognitive Behavioral Therapy and Psychoeducation Program for Patients with Gastrointestinal Stromal Tumors.

Gastrointestinal stromal tumors (GIST) account for 0.2-3% of all cancer diagnoses and are thus considered a rare type of cancer. Severe levels of fatigue occur in 33% of patients on imatinib, but besides treatment, fatigue is also associated with psychological distress.
