Utility of ultrasonography in preoperative assessment of tumor thrombi in kidney cancer.

INTRODUCTION: This study examined the clinical accuracy of ultrasonography compared to magnetic resonance imaging (MRI) and intraoperative findings for evaluation of tumor thrombi level in patients with renal cell carcinoma. MATERIALS AND METHODS: We retrospectively identified 38 patients at our institution who underwent both ultrasonography and MRI before undergoing open radical nephrectomy with tumor thrombectomy between 2010 and 2019. We compared tumor thrombus level findings of both ultrasonography and MRI, as well as the diagnostic accuracy of each to intraoperative findings. Agreement between ultrasonography, MRI, and surgery was tested with kappa. Logistic regression models identified factors that predict a mismatched thrombus level between an imaging modality and surgical findings. RESULTS AND CONCLUSIONS: Tumor thrombus levels determined by ultrasonography matched with MRI in 26 (68.4%) cases. Compared to operative findings, ultrasonography accurately identified the cephalad extent of thrombi in 30 (79.0%) cases, under-staged five (13.2%) cases, and over-staged three (7.9%). Magnetic resonance imaging agreed with operative findings in 30 (79.0%) cases, under-staged five (13.2%) and over-staged three (7.9%) cases. On univariable regression assessment, M1 stage was predictive of a mismatched result between MRI and surgery (OR: 6.0, 95% CI: 1.02-35.3, p = 0.047), but this association did not hold-up in a multivariable model. Ultrasonography and magnetic resonance imaging identified the preoperative tumor thrombus level at a rate of 79%. Ultrasonography is an effective preoperative imaging modality for evaluating tumor thrombi associated with kidney cancer, notably as an adjunct to magnetic resonance imaging.

Longitudinal impact of bladder cancer diagnosis on common psychiatric disorders.

BACKGROUND: The presence of psychiatric disorders in patients with cancer is associated with increased morbidity and poorer outcomes. We sought to determine the impact of a new bladder cancer diagnosis on the incidence of depression and anxiety. METHODS: We used a database of billing claims (MarketScan®) to identify patients newly diagnosed with bladder cancer between 2009 and 2018. Patients with preexisting psychiatric disorders or use of anxiolytics/antidepressants were excluded. We matched cases to patients without a bladder cancer or psychiatric diagnosis. Our primary outcome was a new diagnosis of depression, anxiety, or use of anxiolytics/antidepressants. Other exposures of interest included gender and treatment received. We used multivariable regression to estimate odds ratios for these exposures. RESULTS: We identified 65,846 cases with a new diagnosis of bladder cancer (31,367 privately insured; 34,479 Medicare-eligible). Compared to controls, bladder cancer patients were more likely to develop new-onset depression/anxiety at 6 months (privately insured: 6.9% vs. 3.4%, p < 0.001; Medicare-eligible: 5.7% vs. 3.4%, p < 0.001) and 36 months (privately insured: 19.2% vs. 13.5%, p < 0.001; Medicare-eligible: 19.3% vs. 16.0%, p < 0.001). Women (vs. men, privately insured: OR 1.65, 95%CI 1.53-1.78; Medicare-eligible: OR 1.63, 95%CI 1.50-1.76) and those receiving cystectomy and chemotherapy (vs. no treatment, privately insured: OR 4.94, 95%CI 4.13-5.90; Medicare-eligible: OR 2.35, 95%CI 1.88-2.94) were more likely to develop significant depression/anxiety. CONCLUSION: A new diagnosis of bladder cancer was associated with increased burden of significant depression/anxiety compared with matched controls. Women and patients receiving more radical treatments had higher rates of depression and anxiety.
