Predictive Factors for Functional and Quality of Life Decline in Patients >65 Years With a Gastrointestinal Tract Cancer Diagnosis Taken to Curative Resectable Surgery

Population characterization

To describe demographical, clinical, paraclinical, presurgical functional and of quality of life, and surgical outcomes in patients ≥65 years of age with a gastrointestinal tract cancer diagnosis taken to surgery with a curative intent

Time frame: 5 years

Surgical and functional outcomes

To describe postoperative surgical (mortality and complicactions) and functional and of quality of life outcomes at 1, 6, and 12 months followup in patients ≥65 years of age with a gastrointestinal tract cancer diagnosis taken to surgery with a curative intent

Time frame: 1 year

Oncological outcomes

To describe oncological outcomes (overall survival, disease-free period, disease-specific survival) in patients ≥65 years of age with a gastrointestinal tract cancer diagnosis taken to surgery with a curative intent at 1, 3 and 5 years follow-up

Time frame: 5 years

Comparison

To compare demographical, clinical, surgical, functional and of quality of life, and surgical outcomes in patients ≥65 years of age with a gastrointestinal tract cancer diagnosis taken to surgery with a curative intent that had functional and quality of life decline versus those that did not at 1, 6 and 12 months follow-up

Time frame: 1 year

Qualitative evaluation

To evaluate predictive demographical, clinical, paraclinical factorsfor functional and of quality of life, and surgical for in patients ≥65 years of age with a gastrointestinal tract cancer diagnosis taken to surgery with a curative intent at 1, 6 and 12 months follow-up

Time frame: 1 year

Oncological evaluation

To evaluate predictive demographical, clinical, paraclinical, presurgical, functional and of quality of life, and surgical factors for overall survival, disease-free period and disease-free survival in patients ≥65 years of age with a gastrointestinal tract cancer diagnosis taken to surgery with a curative intent at 1, 3 and 5 years follow-up

Time frame: 5 years

Subgroup analysis

To explore functional and quality of life decline at 1, 6 and 12 months follow-up by subgroups according to decade groups.

Time frame: 1 year

Internal validation

To perform an internal validation of a predictive model for functional and quality of life decline at 12 months follow-up in patients ≥65 years of age with a gastrointestinal tract cancer diagnosis taken to surgery with a curative intent

Time frame: 1 year
