Outcome analysis of geriatric patients undergoing major abdominal cancer surgeries using G8 scoring: a prospective observational study in a tertiary cancer centre in eastern India

The study analyses the association between G8 geriatric scoring with post operative complications. Study participants will be recruited at pre-anesthesia check up clinic being aged 70 years and above, scheduled to undergo major abdominal cancer surgeries. Patients will be classified according to G8 scoring into low, intermediate and high score group. Patients’  ASA  grading, functional status of the patient, tumor type and staging will be assessed. Baseline characteristics of three groups will be compared according to age, gender, type of intervention and cancer grading. Post operative outcomes as occurrence of major and minor complications, length of hospital stay, 30 day readmission and occurrence of post operative delirium will be compared among the groups. As primary outcome, post operative complications are defined and determined using Clavien- Dindo classification. The aim of this study will be to clarify whether G8 scoring, a geriatric screening tool, has independent prognostic value for elderly cancer patients undergoing major abdominal onco surgeries and what is the optimum cut-off  value for predicting complications.
