Comparative Study of Perioperative and Oncological Outcomes Between Elderly Patients and Younger Patients Who Received Radical Cystectomy and Pelvic Lymph Node Dissection: A Single-Center Retrospective Study.

PURPOSE

To compare the perioperative and survival outcomes of patients over 75 years and younger patients who received radical cystectomy.

PATIENTS AND METHODS

A total of 119 patients aged ≥75 years and 488 patients aged <75 years were enrolled. All patients underwent radical cystectomy with pelvic lymph node dissection. Clinical characteristics and perioperative outcomes were compared between the two groups. Overall survival and progression-free survival were analyzed by using the Kaplan-Meier method. Cox regression analysis and logistic regression analysis were used to identify the risk factors affecting the outcomes observed.

RESULTS

There was no significant difference in perioperative complications between the elderly patient group and the younger patient group ( = 0.349). The 5-year overall survival of elderly patients was lower than that of young patients (p < 0.001). Age ≥75 years was a risk factor for overall survival (HR = 1.69 [95% CI: 1.22-2.35]; p = 0.002) and progression-free survival (HR = 1.69 [95% CI: 1.14-2.50]; p = 0.008) for patients who received radical cystectomy but was not a poor risk factor for major complications (HR = 1.25 [95% CI: 0.47-3.31]; p = 0.658) after radical cystectomy. In addition, preoperative renal insufficiency was associated with a higher risk of major complications.

CONCLUSION

In our cohort, compared with younger patients, elderly patients aged ≥75 years had worse survival outcomes, but age ≥75 years was not a risk factor for major complications after radical cystectomy with pelvic lymph node dissection. Radical surgery should be encouraged for elderly patients who can tolerate aggressive treatments.
