Neoplastic diseases (ND) and chronic kidney disease (CKD) are strongly related. Side effects of neoplastic treatments can cause CKD and the latter can be a risk factor for ND. Even in early stages of CKD, the risk of developing ND increases, the latter being drastically increased in patients (pts) treated with hemodialysis.Objectives
Compare, within a population of cancer pts with and without CKD, demographic characteristics, length of hospital stay, and prognosis.Methods
Observational prospective study with all consecutively admitted pts in an Internal Medicine department of a CentralHospital between November 2010 and October 2011. Collection of data using a previously normalized questionnaire, completed on admission and date of release, finalized with a posterior telephonic contact. The following characteristics of pts with ND and CKD (GFR CKD < 60 mL/min/1,73m2) - GROUP A (GA) and with ND but without CKD - GROUP B (GB) were compared: demographics, in-hospital evolution, hospital stay and post-release mortalitiesResults
We evaluated 104 pts with ND with an average follow-up of 162 days.GA= 40 pts (38,5%) 78,9 ± 10,6 years, 52,5% women, GFR =39,6 ±12 mL/min/1,73m2, stages III = 77,5%, IV = 22,5% GB= 64 pts (61,5%), 72,92 ± 12,6 years; 46,9% women, GFR = 72,9 ± 14,5mL/min/1,73m2. Hospital stay length: GA 9,2 ± 5 vs GB 9.9 ± 9,3 days. Hospital stay mortality: GA: 27,5% VS GB: 3,125%. CKD correlates with hospital-stay mortality: (?2(2) = 13,371; p = 0,000 N = 104.); Significant differences were found between both groups pertaining to average survival during follow-up: (t(52) = -3,437; p = 0,01). The average length of hospital-stay and the number of readmissions are not related to the existence of CKD: (?2(2) = 0,399; p = 0,53 N = 90)Conclusion
More than 1/3 of ND pts had CKD, the majority within stage III. ND pts with CKD were older. CKD contributed to hospital stay mortality and shorter survival rate on follow-up of pts with ND but did not contribute to an increase of hospital stay length.Disclosure
