Objective To compare effect of Nutrition Risk Screening Scale 2002(NRS-2002) and Controlling Nutritional Status (CONUT) score in evaluating prognosis of high-grade T1 stage bladder cancer.
Methods A total of 96 cases of high-grade T1 stage bladder cancer treated by transurethral rescetion of bladder tumor (TURBT) were collected. All patients were evaluated by NRS-2002 score. Serum albumin, peripheral lymphocyte count and total cholesterol were measured and CONUT score was calculated. These patients were divided into low NRS group (n=60) and high NRS group (n=36), low CONUT group (n=53) and high CONUT group (n=43) according to conditions of NRS-2002 and CONUT scores. The recovery and survival status of patients in different groups were compared.
Results Bed-off ambulance time and hospital stay in the high CONUT group and the high NRS group were significantly longer than those in the low CONUT group and low NRS group (P < 0.05). Survival analysis showed that there was no difference in progression-free survival (PFS) between the high NRS group and low NRS group(P>0.05), but the overall survival (OS) of the low NRS group was significantly better than that of the high NRS group (P < 0.05). PFS and OS in the low CONUT group were significantly higher than those in high CONUT group (P < 0.05). NRS was a related factor but not an independent factor of OS, while CONUT score was an independent factor of both PFS and OS.
Conclusion The preoperative NRS and CONUT scores of bladder cancer patients were both correlated with prognosis, but the prognostic value of CONUT score is better than that of NRS score.
