is a widely used nucleoside analog approved for treatment of several types of cancers. Gem administration is known to induce glomerular thrombotic microangiopathy, resulting in the emergence of proteinuria and/or kidney dysfunction. This study was undertaken to ascertain both incidence of proteinuria and an association between incident proteinuria and mortality in Gem recipients. Methods: A prospective cohort study was conducted in 67 non-proteinuric patients with pancreatic or biliary cancer (35 men, mean age, 68 years), PI3K inhibitor who received the first mono-therapy of Gem and who lived more than 6 months. Incident proteinuria was defined as dipstick test ≥1 +, persistent in at least two consecutive examinations within 6 months following Gem administration. Cumulative mortality was analyzed by the Kaplan-Meier method,

stratified by presence and absence of incident proteinuria. Multivariable Cox proportional hazards regression analysis was used to calculate hazard ratio (HR) with its 95% confidence interval (CI) for all-cause mortality, adjusted for age, gender, stages of the disease, and estimated glomerular filtration rate (eGFR). Results: Incidence of proteinuria was 25.3% in the first 6 months, and mortality rate was 65.7% in the follow-up period (median, 393; range, 184–1004

days). Cumulative mortality was significantly greater in patients who developed proteinuria (65.2%) than those who did not (36.6%) at the time of 393 days following the Gem administration. [figure]. The HR (95% CI) of proteinuria incidence for mortality was 2.60 (1.24–5.24; P = 0.0126), as compared with the opponent. [table]. Conclusion: Incidence of proteinuria may be a harbinger of near-term death in Gem recipients.

Methods: This cross sectional study population was divided into two groups group with group 1 or the early CKD group population comprising of CKD patients with GFR ranging from 30–89 ml/min and group 2 or the late CKD group population comprising if patients with GFR ranging from 15–29 ml/min.
