Children undergoing thyroidectomy/parathyroidectomy have higher complication rates than adult patients. Outcomes were optimized when surgeries were performed by high-volume surgeons. There appears to be disparity in access to high-volume surgeons for children from low-income families, Blacks, and Hispanics.

In the National Cancer Database, adjuvant chemotherapy remained efficacious when started 7 to 18 weeks after non-small-cell lung cancer resection. Patients who recover slowly from non-small-cell lung cancer surgery may still benefit from delayed adjuvant chemotherapy started up to 4 months after surgery.

Eosinophils have been identified as a prognostic marker in immunotherapy of melanoma and suggested to contribute to anti-tumor host defense. However, the influence of immune checkpoint inhibitors (ICI) on the eosinophil population is poorly studied. Here, we applied routine laboratory tests, multicolor flow cytometry, RNA microarray analysis, and bio-plex assay to analyze circulating eosinophils and related serum inflammatory factors in 32 patients treated with pembrolizumab or the combination of nivolumab and ipilimumab. We demonstrated that clinical responses to ICI treatment were associated with an eosinophil accumulation in the peripheral blood. Moreover, immunotherapy led to the alteration of the eosinophil genetic and activation profile. Elevated serum concentrations of IL-16 during ICI treatment were found to be associated with increased frequencies of eosinophils in the peripheral blood. Using immunohistochemistry, we observed an enhanced eosinophil degranulation and a positive correlation between eosinophil and CD8 + T cell infiltration of tumor tissues from melanoma patients treated with ICI. Our findings highlight additional mechanisms of ICI effects and suggest the level of eosinophils as a novel predictive marker for melanoma patients who may benefit from this immunotherapy.
