Impact of marital status in patients undergoing radical cystectomy for bladder cancer

Married (vs. unmarried) individuals have improved health status and longer life expectancies in a variety of benign and malignant disease states, including prostate, breast, head/neck, and lung cancers. We sought to evaluate a cohort of patients undergoing cystectomy for bladder cancer to evaluate the impact of marital status on demographic, peri-operative, and pathological outcomes in order to better understand the factors which may contribute to the survival differences observed.

Two-hundred and two patients underwent radical cystectomy and urinary diversion for bladder cancer. Patients were categorized based on marital status as either married or unmarried (widowed, divorced, never married). Correlations were made to demographic factors (age, race, gender, BMI, tobacco use, alcohol use), perioperative factors (pre-op renal function (creatinine), hematocrit, EBL, hospital stay, choice of diversion), and pathological outcomes (organ-confined status, LN positivity).

Of the 202 patients, 74% were married. Married individuals (vs. unmarried) were more often male (84 vs. 62%) and had a higher BMI (28.1 vs. 25.9). Married persons had a significantly lower pre-op creatinine (1.1 vs. 1.4) and higher hematocrit (39 vs. 34). Hospital stay was shorter in married patients by a mean of 1.6 days. Regarding operative pathology, married patients had a higher rate of organ-confined disease (59 vs. 47%) (P = 0.05, 0.08 on multivariate) and trended towards a lower rate of LN positivity (15 vs. 21%; P = 0.10, 0.12 multivariate).

In patients undergoing cystectomy for bladder cancer, married individuals appear to have improved pre-operative laboratory variables, shorter hospitalization, and improved pathological outcomes versus unmarried patients in our case series. These findings may support the evidence (observed in other tumor types and other disease states) that married persons present earlier than unmarried individuals, and this may help explain the improved survival outcomes that have been observed in married patients with bladder cancer.
