The application of gemcitabine and pirarubicin in patients with non-muscle invasive bladder cancer

Abstract

Objective: To investigate the value of gemcitabine and pirarubicin in patients with non-muscle-invasive bladder cancer (NMIBC).

Methods: 405 patients with non-muscle invasive bladder cancer admitted to our hospital from January 2012 to December 2020 who underwent transurethral bladder tumor electronic resection were studied. 177 patients were treated with gemcitabine (Gemcitabine group) and 228 patients were treated with pirarubicin (Pirarubicin group) after surgery. The efficacy and adverse effects of the two groups were observed and the patients were followed up.

Results: No differences were found when comparing age, gender, smoking, bladder mass, number of masses, hypertension, diabetes, coronary artery disease, hematuria and tumor diameter between the 2 groups (P > 0.05). In the Gemcitabine group, bladder irritation signs, meatus hematuria, fever, nausea and vomiting were lower than those in the Pirarubicin group (P < 0.05). The recurrence rates were 6.21% and 12.28% at 1 year, 11.86% and 23.68% at 2 years, 15.82% and 25.88% at 3 years in the Gemcitabine and Pirarubicin groups respectively, with the Gemcitabine group having a significantly lower recurrence rate than the Pirarubicin group (P < 0.05). The tumor recurrence-free survival rate for 5 years of gemcitabine was significantly higher than that of the Pirarubicin group (P < 0.05).

Conclusion: Gemcitabine and pirarubicin are both effective in treating patients with non-muscle invasive bladder cancer, with gemcitabine having a lower incidence of adverse reactions, a higher safety rating, a lower recurrence rate and an improved survival outcome.
