Subjects will perferm 30-minute net aerobic exercise sessions at moderate intensity (3-5 METS, 60%-70% of maximum heart rate) three times per week. Participants may choose from walking, cycling, or swimming, with the option to alternate activities to enhance adherence to the program. Each session will include 10 minutes of warm-up (gradual increase in intensity); 30 minutes of aerobic exercise and 10 minutes of cool-down (gradual reduction of intensity and optional stretching). Total weekly exercise duration will be 150 minutes.

Identify changes in the quality-of-life score from the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 (v3). The EORTC QLQ-C30 (v3) evaluates health status through nine multi-item scales: Five functional scales (physical, role, cognitive, emotional, social); three symptom scales (fatigue, pain, nausea/vomiting); one global health status scale. Additionally, six single-item scales assess symptoms commonly associated with neoplastic disease and its treatment (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties).

Assess possible changes in physical symptomps with the pancreas-specific PAN26 questionnaire. The PAN26 questionnaire consists of 26 four-level items, producing seven multi-item scale scores (each composed of two to four items) and nine single-item scores.
