Patients in the control group received standard treatment and care at the hospital where they were followed up. Initial interviews with patients were conducted in person. After obtaining verbal and written consent from patients who volunteered to participate in the study, the "Edmonton Symptom Assessment Scale" and the "Functional Assessment in Cancer Treatment-Colorectal Cancer Scale" were administered. The same scales were administered again via telephone one month (second follow-up) and three months (final follow-up) after the initial data collection.

Institutional Standard Care: At the institution where the study was conducted, patients receiving chemotherapy were informed by their primary nurse about the medication protocol, drug-related side effects, and possible symptoms. They were also given educational brochures on topics such as pain, nausea, and precautions to take when using port needles. Nurses in the outpatient chemotherapy unit additionally planned the patients' treatm

Experimental Group Patients in the experimental group used the web-based "Meet in Health Support Care Program" for 3 months in addition to routine care.

The initial interview with the patients was conducted face-to-face. Verbal and written consent was obtained from patients who volunteered to participate in the study. During the interview, the goal and content of the study were explained, the website was introduced, and information on its use was provided. In addition, the Edmonton Symptom Assessment Scale and the Functional Assessment in Cancer Treatment-Colorectal Cancer Scale were administered during the first interview. One month (second follow-up) and three months (final follow-up) after the collection of the initial data, the same scales were administered again by telephone interviews with the patients. In the final follow-up (3rd month), the "Website Usability Scale" was administered to the patients to evaluate their satisfaction with the support care program.

This study developed a supportive care program for individuals diagnosed with colorectal cancer who are undergoing cancer treatment, focusing on the symptoms and quality of life experienced by patients during treatment.

The sub-headings and content of the planned program were prepared within the framework of the "Supportive Care Framework," frequently used for cancer patients. This framework, comprising 7 main concepts (physical, emotional, social, psychosocial, spiritual/mental, informational, and practical-daily life changes), aims to provide a holistic approach to patients' needs.

Furthermore, the program content includes the experiences of individuals who have gone through similar experiences and have recovered from cancer. All these approaches constitute the unique values of this study.

The Functional Assessment in Cancer Treatment-Colorectal Cancer Scale (FACT-C) was administered to evaluate the quality of life of patients undergoing chemotherapy. The scale is part of the Functional Assessment in Chronic Disease Treatment (FACIT) measurement system and is used to assess common conditions seen in all cancer patients, as well as specific concerns associated with colorectal cancer.

The Edmonton Symptom Assessment Scale was used to evaluate the symptoms experienced by patients during chemotherapy treatment. The scale assesses 10 symptoms: pain, fatigue, nausea, sadness, anxiety, insomnia, loss of appetite, general malaise, shortness of breath, and other problems.
