1.2.1. To categorize, by using the patient rated multiple symptom assessment tool MD Anderson Symptom Inventory (MDASI), the longitudinal course of the multiple symptoms experienced by pancreatic cancer patients with metastatic disease.
1.2.2. To explore the relationships between cancer symptoms and polymorphisms of genes relating to inflammation, chemotherapeutic drug and opiate metabolism.1.2.3. To explore the association of inflammatory cytokines, such as IL-6 and TNF-alpha, with disease-driven symptom development and its predictive value for survival in pancreatic cancer patients.
1.2.4. To evaluate the association between objective measures of physical function (via daily step count), component scores of patient reported physical symptom severity, and physician reported performance status (ECOG PS). |
