Although our findings show no association between blood group and five-year survival, these results are inconclusive, and warrant further study of the association between blood type and laryngeal (and other) head and neck cancers.

In a population based cohort, two-thirds of men diagnosed with prostate cancer qualify for active surveillance. Less restricted criteria for surveillance may be appropriate based on similar rates of upgrading/up staging at radical prostatectomy.

Background:Renal cancer may invade the inferior vena cava (IVC) creating more complex surgical intervention. We investigate radiologic findings that may predict vascular reconstruction prior to surgery and future renal cancer-specific mortality.Materials and Methods:Radiologic findings included Mayo Clinic risk factors for vascular reconstruction: Right-sided tumor, anteroposterior diameter of the IVC at the ostium of the renal vein ≥24.0 mm, and radiologic identification of complete occlusion of the IVC. Additional factors included thrombus in the lumen of the hepatic veins and metastasis. Along with other demographic factors, analysis included Chi-squared analysis for vascular reconstruction and logistic regression for mortality. A Kaplan–Meier curve was created for the most significant radiologic factor.Results:Thirty-seven patients underwent IVC tumor thrombectomy at two institutions from April 2007 to February 2015. We found that Mayo risk factors of 0, 1, 2, and 3 and the proportions of vascular reconstruction of 0%, 0%, 12.5%, and 13.6%, respectively (P = 0.788). Hepatic vein involvement was the most significant determinate of renal cell carcinoma-specific mortality in multivariable analysis, controlling for the size of IVC at the hepatic veins, pulmonary metastasis, and Fuhrman grade (P = 0.02, Log-rank P = 0.002).Conclusion:Mayo risk factors did not predict vascular reconstruction in our small cohort of Level II–Level IV IVC thrombus undergoing IVC thrombectomy. Tumor thrombus traveling into the lumen of the hepatic veins was a significant risk factor for accelerated mortality.
