Brief Summary

Introduction: With the increasing survival rate in colon cancer, as a result of technological and biomedical advancements, it is essential to thoroughly study the secondary symptoms related to the oncological disease process. One of the most common and underestimated symptoms is cancer-related cognitive impairment (CRCI).

Objective: To evaluate the efficacy of a cognitive training program in controlling CRCI in individuals with colon cancer undergoing active treatment.

Methodology: A randomized controlled clinical trial with two parallel groups: an intervention group (IG) and a control group (CG). The study population will include individuals newly diagnosed with colon cancer. A sample size of 50 participants has been estimated, with 25 in each group, to detect a difference of 2.95 points or more in the MoCA cognitive impairment questionnaire. All participants will receive an educational leaflet based on the new WHO guidelines, which recommend specific measures to reduce the risk of cognitive impairment. In addition to receiving this informational leaflet, the IG will participate in a cognitive training program (CT) focused on everyday cognition (EC) individually. Each participant will receive a dossier with 80 intervention sessions divided into four training periods (P1-P4), each containing 20 activities. Each period will last for one month. Baseline and 4-month post-intervention evaluations will be conducted for both groups, measuring sociodemographic and clinical variables, as well as study-related cognitive impairment variables: Cognitive function (MoCA test), Everyday Cognition (PECC), Anxiety (Hamilton), Functionality (LB), Sleep Quality (PSQI), Quality of Life (ECOG), and Subjective Memory Complaints (FACT-COG).

Impact: The results of this study could lead to the design of specific cognitive interventions and the establishment of protocols for colon cancer patients undergoing active treatment, helping them manage one of the most underestimated symptoms in this patient population-CRCI-whose incidence is increasing due to the improved survival rates in this disease.

Study & Design

• Study Design: PARALLEL

Primary Outcome Measures

Name	Time	Method
Cognitive Function	Baseline; "4 months final";	The Montreal Cognitive Assessment Test (MoCA test) Version 8.3" (17): This test allows the detection of mild cognitive impairment (MCI) by evaluating executive functions, attention, abstraction, memory, calculation, and orientation. The administration time is 10 minutes. The maximum score is 30 points, with scores below 26 indicating MCI.
Subjective Perception of Cognitive Impairment in Oncology Patients	Baseline; "4 months final";	FACT-COG (Version 3)" (24): This 37-item questionnaire is divided into six cognitive domains: memory, concentration, mental acuity, verbal fluency, functional interference, and multitasking ability. Additionally, the tool includes two other subscales: "notability" (comments from others) and "impact of perceived cognitive impairment on quality of life." Respondents indicate the frequency of each occurrence during the 7 days prior to the test on a 5-point Likert scale ranging from 0, "never," to 4, "several times a day." The individual subscale scores are summed to determine the total FACT-Cog score, which ranges from 0 to 148, with higher scores indicating better cognitive functioning.

Secondary Outcome Measures

Name	Time	Method
Everyday Cognition	Baseline; "4 months final";	Test for the Evaluation of Everyday Cognition (PECC)" (18): This test measures individuals' ability to solve 12 real-life situations grouped into the following areas: medication management, administrative management, financial management, meal preparation, transportation, and shopping. It helps assess functional capacity in daily life. The administration time is 35 minutes.
Anxiety	Baseline; "4 months final";	Hamilton Anxiety Rating Scale" (19): A clinical assessment tool used to evaluate the level of anxiety experienced by a person. It consists of 14 items, each with five response options ranging from "not present" to "very severe," with a score assigned to each response. A total score of 17 or less indicates mild anxiety; 18 to 24 indicates moderate anxiety; and 25 to 30 indicates severe anxiety.
Functionality	Baseline; "4 months final";	Lawton and Brody Instrumental Activities of Daily Living Scale" (20): Designed to assess autonomy in instrumental activities in the elderly population. The administration time is 4 minutes, and each item is scored as 0 or 1, with a total score of 8.
Sleep Quality	Baseline; "4 months final";	Pittsburgh Sleep Quality Index (PSQI)" (21): Developed to measure sleep quality in individuals aged 24 to 83 years. The administration time is 5-10 minutes. Nineteen individual items generate seven "component" scores: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleep medication, and daytime dysfunction.
Subjective Memory Failures	Baseline; "4 months final";	Everyday Memory Failures Questionnaire" (23): This questionnaire includes categories of forgetfulness such as "speaking, reading, and writing," "names and faces," "actions," and "learning new things." Responses are given on a Likert scale with nine response options for each question, ranging from "Never in the past 3 months" to "More than once a day." However, due to the difficulty of the nine options, other authors have used fewer response choices.
