The Impact of an Educational Intervention on Disease Acceptance, Quality of Life, Pain Levels, and Postoperative Clinical and Biometric Outcomes Among Patients Undergoing Surgery for Lung Cancer.

This is a two-arm parallel-group interventional study evaluating the impact of a structured educational intervention in patients undergoing surgery for lung cancer. The study is conducted at a referral center, where all interviews, educational sessions, follow-up assessments, and data collection procedures take place.

Before enrollment, all eligible patients receive written information about the study and provide written informed consent. By signing the consent form, participants give permission for the researcher to collect study-related data through personal interviews and from their medical records.

Baseline preoperative data are collected from all participants before the delivery of the educational intervention. These data are collected using specially designed questionnaires administered through personal interviews with the patient and include demographic characteristics, hospital admission information, biometric measurements, lifestyle-related factors such as smoking, physical activity, dietary habits and alcohol consumption, as well as personal and family medical history.

Participants are allocated to either an intervention group or a control group. Allocation is performed using a predefined alternating sequence according to the order of surgery. On the first surgical day of the study, the research team determines the initial group assignment for the first eligible participant undergoing the first scheduled surgery. Subsequently, eligible participants are allocated alternately to the intervention and control groups according to the order of surgery. On the next surgical day, the allocation sequence starts with the opposite group, and this alternating pattern continues throughout enrollment.

The intervention group receives usual care plus a structured educational intervention supported by printed educational material. Participation of a caregiver is required during the educational session together with the patient. The printed material includes the date of the educational intervention, the researcher-educator's contact details, and the scheduled follow-up appointment.
