Thyroid nodules are common, and of those biopsied by fine-needle aspiration (FNA), the majority will be benign colloid nodules (BCN). Current guidelines suggest these BCN should be followed by ultrasonographic examination (US) every 3 years, with no endpoint specified. This study evaluated if long-term follow-up of benign thyroid nodules was associated with change in treatment or improvement in diagnosing a missed malignancy compared with short-term follow-up. ⋯ Long-term follow-up of patients with BCN is associated with increased repeat FNA and US without improvement in the malignancy detection rate. After 3 years of follow-up, consideration should be given to ceasing long-term routine follow-up of biopsy-proven BCN.

Multicenter Study Comparative Study
Incidence of sentinel lymph node involvement in a modern, large series of desmoplastic melanoma.
Recent studies have suggested that sentinel lymph node (SLN) biopsy is of limited value in desmoplastic melanoma. This study was performed to compare the rate of positive SLN biopsy in the Surveillance, Epidemiology, and End Results (SEER) database with that of a multi-institutional clinical trial and to investigate relevant prognostic factors in desmoplastic melanoma. ⋯ The rate of positive SLN in desmoplastic melanoma may be higher than that reported in the SEER database. Sentinel lymph node biopsy may be considered as part of the comprehensive staging of desmoplastic melanoma ≥1.0 mm Breslow thickness.

The primary reported indication for the associating liver partition with portal vein ligation for staged hepatectomy (ALPPS) technique is in patients with very low future liver remnant volumes. Given the elevated incidence of major morbidity (40%) and liver-related mortality (12%) with ALPPS, we sought to determine the safety and efficacy of percutaneous portal vein embolization (PVE) in a similar patient population. ⋯ Based on its ability to select oncologically resectable patients and superior safety and efficacy profiles, percutaneous right + segment IV PVE and interval surgery remains the standard of care for patients with very low future liver remnant volumes.

The American College of Surgeons Oncology Group Z0011 trial results provided convincing evidence that completion axillary lymph node dissection (CALND) was unnecessary in selected patients with 1 to 2 positive sentinel lymph nodes (SLNs). We hypothesized that preoperative axillary ultrasound (AUS) with fine-needle aspiration is sufficiently sensitive to detect worrisome macrometastasis to preclude the need for frozen-section pathology of SLNs. ⋯ The addition of preoperative AUS with or without fine-needle aspiration to management of patients who meet American College of Surgeons Oncology Group Z0011 trial eligibility criteria reduced the risk of macrometastasis measuring ≥6 mm to only 2%; very few of these patients would be premenopausal, have estrogen receptor-negative tumors, or ≥3 positive SLNs. With the addition of AUS with or without fine-needle aspiration, we endorse the conclusions of the American College of Surgeons Oncology Group Z0011 trial to avoid CALND, and see marginal gain in frozen-section analysis of SLNs.

Trauma care is often delivered to unstable patients with incomplete medical histories, under time pressure, and with a need for multidisciplinary collaboration. Trauma patient flow through radiology is particularly prone to deviations from optimal care. A better understanding of this process could reduce errors and improve quality, flow, and patient outcomes. ⋯ Although flow disruptions cannot be eliminated completely, specific targeted interventions are available to address the issues identified.
