Purpose: We aim to investigate the potential association of the nutrition status, and comorbidity such as Diabetes mellitus with the prognosis of upper urinary tract urothelial carcinoma.
Materials and Methods: In this retrospective cohort study, we analyzed data from patients who came to Kaohsiung Chang Gung Memorial Hospital between January 1, 2005, to December 21, 2020, under the diagnosis of upper tract urothelial carcinoma and received surgical intervention. Patient characteristics including age, sex, tumor staging, comorbidities, glucose variability with visit-to-visit HbA1c coefficient variation, nutritional status were collected. The prognostic factors were overall survival, cancer-specific survival, recurrence-free survival, and metastasis-free survival.
Results: Total 1245 patients were diagnosed with upper tract urothelial carcinoma and received nephroureterectomy during our observation period. Define the albumin cutoff level at 3.5g/dL, the group with better nutrition status had better overall survival, but no significant difference for recurrence-free survival and metastasis-free survival. Patients with well control of diabetes mellitus would have better outcomes.
Conclusions: The pre-operative albumin, which may represent peri-operative nutrition status, was associated with the prognosis of upper urinary tract urothelial carcinoma in our 15-year follow up. Patient with better nutritional status before the operation may have better overall survival.
