The incidence of thyroid cancer in patients treated operatively for thyroid disease has been historically low (<5%). Previous series have not specifically addressed cancer rates in both euthyroid and hyperthyroid patients. This study examined cancer frequency in patients referred for removal of benign thyroid disease in a multi-institutional series. ⋯ These data confirm higher than expected incidental thyroid cancer rates (15.6%) in the largest multi-institutional surgical series to date. Nodular thyroids, males, and young patients were more likely to harbor incidental carcinoma. These data support consideration of initial total thyroidectomy as the preferred approach for patients referred to the surgeon with bilateral nodular disease.

The hypercoagulable state associated with cancer imparts considerable risk for venous thromboembolism. Surgical resection of malignancies should theoretically reverse tumor-induced hypercoagulability. However, coagulation changes in cancer patients postresection have not been described thoroughly. Conventional coagulation tests are unable to detect hypercoagulable states. In contrast, rotational thromboelastography (ROTEM) can detect hypo- or hypercoagulable conditions. We hypothesized that the cancer-induced hypercoagulable state would improve after surgical resection. ⋯ Rotational thromboelastography identifies baseline hypercoagulability in more than one third of patients with intra-abdominal malignancies. This is among the first studies to demonstrate progressive hypercoagulability that persists for at least 1 month after resection. These data support postdischarge thromboprophylaxis regimens in high-risk cancer patients.

Stakeholders derive many benefits from cancer clinical trials, including guidance for future oncologic treatment decisions. However, whether enrollment in cancer trials also improves patient survival independently of trial outcomes remains underinvestigated. We hypothesized that cancer trial enrollment is not associated with patient survival outcomes. ⋯ In this first population-based study examining trial effect in solid organ cancers, enrollment into cancer trials predicted lower overall and cancer-specific mortality among common cancer sites. Although these findings may demonstrate a survival benefit due to trial enrollment, they likely also reflect the favorable attributes of trial enrollees. Once corroborated, stakeholders must consider broader cancer trial designs representative of the cancer burden treated in the real world.

Current guidelines recommend minimally invasive breast biopsy (MIBB) as the gold standard for the diagnosis of breast lesions. The purpose of this study was to describe geographic patterns and time trends in the use of MIBB in Texas. ⋯ Despite an increase in the use of MIBB over time, MIBB use was consistently lower than recommended. We must identify specific barriers in rural areas to effectively change practice and achieve the statewide goal of 90% MIBB.

Initiatives to increase arteriovenous fistula (AVF) use are based on studies that show that AVFs require fewer interventions and have better patency than arteriovenous grafts (AVGs). Because patients who receive AVFs typically have more favorable vascular anatomy and are referred earlier for access placement than those who receive AVGs, the advantages of AVF might be overestimated. We compared outcomes for AVFs and AVGs in patients with equivalent vascular anatomy who were on dialysis via catheter at the time of vascular access placement. ⋯ For patients who are receiving dialysis via catheter at the time of access placement, the maturation time, risk of nonmaturation, and interventions required to achieve a functional AVF can negate its benefits over AVG. A fistula first approach might not always apply to patients who are already on dialysis when referred for chronic access placement.
