Survival and metastasis in muscle-invasive bladder cancer patients who present with indeterminate pulmonary nodules before treatment.

Abstract：

BACKGROUND:Indeterminate pulmonary nodules (IPNs) are common during initial evaluation of bladder cancer patients. Their significance is still unknown. OBJECTIVE:Determine the significance of indeterminate pulmonary nodules, including their size and number, in muscle-invasive bladder cancer patients before definitive local therapy by surgery or chemo-radiotherapy. DESIGN:Retrospective review, single-center descriptive study. SETTINGS:A tertiary cancer center. PATIENTS AND METHODS:We performed a retrospective review of patients who underwent definitive local therapy of bladder cancer by either radical cystectomy and lymph node dissection or with chemo-radiotherapy between January 1997 and December 2015. We identified patients with baseline CT scans done during staging work-up prior to definitive treatment. Patients with proven clinical metastasis at pre.sentation were excluded, while patients who had IPNs without features suggesting metastasis were included. MAIN OUTCOME MEASURES:Disease-free survival and overall survival. SAMPLE SIZE:168 patients. RESULTS:The median age of patients at diagnosis was 66 years; 92% were males and 56% were smokers. IPNs (3 cm or less) were present in 74 patients (44.0%). Median follow-up was 24 months. IPNs were associated with decreased disease-free survival while IPNs did not affect the overall survival (HR=1.9; 95% CI: 1.1-3.4); P=.01 and HR=1.5; 95% CI: 1.0-2.5); P=.07, respectively. In addition, nodules greater than 1 cm had reduced disease-free survival (HR=2.5; 95% CI: 1.1-5.9); P=.04. In the surgery group (n=126), the median number of lymph nodes excised was 14, with no association between lymph nodes status and the presence of IPNs (P=.08). CONCLUSION:The presence of IPNs, especially nodules greater than 1 cm had a negative effect on disease-free survival. Tailored postoperative follow-up of these patients may impact disease outcomes. LIMITATIONS:The retrospective nature, the lack of standardized preoperative imaging protocols, the lack of a central radiology review and the small number of patients. CONFLICT OF INTEREST:None.
