Chemotherapy Side Effects

The main questions it aims to answer are: 1. Does completing a standard assessment increase the detection of chemotherapy induced taste changes compared with usual care (no assessment)? What TA are experienced? Are there any patterns in TA symptom occurrence based on age, sex, race/ethnicity, cancer type, chemotherapy agent, etc. 2. Do patients take action to deal with the TA? What strategies are used? Do patients in the intervention group use the assessments to select interventions? 3. Do the interventions lessen TA symptoms and maintain food intake? Is the treatment (in-depth assessment and education) more effective in lessening the intensity of TA than usual care? Which level of assessment is needed to support symptom management to reduce symptom severity? Participants will: Complete baseline assessment before starting their initial chemotherapy infusion (all patients) Participate in baseline patient education based on assigned intervention (usual care vs. treatment) Engage in TA management between chemotherapy infusion clinic visits based on education Visit the clinic for chemotherapy infusions as scheduled; Complete TA assessments and reporting based on intervention; Work with nurse coaches to answer questions and help with the intervention. Complete study data collection on the 4th chemotherapy cycle (but continue intervention) Complete final data collection at 6 months

This study hypothesizes that approximately 50% of rectal cancer patients can preserve their rectum using a watch-and-wait strategy if they achieve a complete or near-complete clinical response to total neoadjuvant therapy (TNT). The objective is to determine whether the complications, quality of life, and survival rates of rectal cancer patients who have achieved a complete or near-complete clinical response to TNT, followed by a watch-and-wait approach, are comparable to those of patients who undergo surgery first. Additionally, the study aims to identify potential prognostic and predictive markers for rectal cancer and examine survival rates and factors influencing responses to chemoradiotherapy (CRT) or TNT. The study is divided into two parts: \*\*Part One:\*\* Participants with cT1N1, T2-T3 N0-1 rectal cancer, MRF-, and EMVI-, with surgery as one of the possible first-line treatment options, will be randomized into two groups. The experimental group will consist of participants receiving TNT, including CRT and consolidation chemotherapy (Ch). If these participants achieve a complete or near-complete clinical response, they will be observed using a watch-and-wait strategy, which is a non-operative approach. The control group will consist of participants who undergo surgical treatment initially. \*\*Part Two:\*\* All participants with rectal cancer who have received CRT or TNT will be included. Additionally, participants diagnosed with rectal cancer who are scheduled for CRT or TNT but declined to participate in Part One or do not meet the inclusion criteria will also be included.

The growing U.S. cancer survivor population is projected to hit 26M by 2040. Chemotherapy represents an effective cancer treatment but can diminish cancer survivors' quality of life-particularly cognitive function-through select pathophysiological processes. Research on chemotherapy-induced cognitive impairment (hereafter, 'chemo-brain') is therefore critical. Chemotherapy disrupts immune system function and antioxidant regulation, causing inflammatory molecule release and damaging the brain's blood vessels. The brain's vascular function and, possibly, its neurons, are subsequently impaired-likely contributing to chemo-brain. Type 2 diabetes (T2D), a common cancer survivor comorbidity, shares underlying pathophysiology with chemo-brain. T2D-related insulin resistance can precipitate repeated high blood sugar episodes which increase inflammatory molecule release. In individuals with T2D without cancer, negative relationships are observed between inflammatory molecule concentrations and the brain's vascular and/or cognitive function. Cancer survivors with T2D might thus have higher chemo-brain risk than those without T2D. Yet, more research must compare how the brain's vascular function, as well as cognitive, inflammatory, and cardiometabolic indices, differ between these groups. Physical activity (PA) counteracts chemo-brain's and T2D's pathophysiology, with higher PA/fitness resulting in better vascular function of the brain, lower inflammatory molecule concentrations, and improved insulin sensitivity. We are therefore conducting a 30-participant quasi-experimental pilot study in cancer survivors with (cases) and without (controls) T2D. We will first investigate between-group differences in the brain's vascular function as well as cognitive, inflammatory, cardiometabolic, and epigenetic outcomes. We will then examine between-group changes in these outcomes and select psychosocial metrics during a 12-week technology-based PA program-potentially further elucidating involved mechanisms.

The goal of this clinical trial is to learn if a standardized pharmacists-provided education module by social media can improve patients' knowledge of chemotherapy-related side effects. The main questions it aims to answer is: • Do patients who received a standardized pharmacists-provided education module by social media improve their knowledge of chemotherapy-related side effects? Researchers will compare standardized chemotherapy education +video (experimental group) versus chemotherapy handouts (control group). Participants will: * Received standardized chemotherapy education + video or chemotherapy handouts at the first and second chemotherapy section. * Fill out a questionnaire for outcomes assessment.
