Sentinel lymph node biopsy (SLNB) is currently recommended for patients with intermediate-thickness melanomas (T2-T3). Historically, T4 melanoma patients have not been considered good candidates for SLNB because of the high risk of distant progression. However, some authors suggest that T4 melanoma patients could be considered as a heterogeneous group that could benefit from SLNB. ⋯ We confirmed that thick-melanoma patients are a heterogeneous group with different prognosis. In our experience, SLNB allowed for an appropriate stratification of patients in different survival groups. On the basis of our results, we strongly recommend the routine execution of SLNB in cases of primary melanoma thicker than 4 mm.

Surgical oncologists (SO) and hepatobiliary (HPB) surgeons frequently care for patients with advanced diseases near the end of life, yet little is known about their training, comfort, and readiness in the provision of palliative care. This study sought to assess the quality, adequacy, and extent of palliative care training and the readiness of SO and HPB fellows in delivering palliative care. ⋯ The fellows rated the quality of their palliative care education as poor compared with other aspects of their fellowship training, implying the lack and need of palliative care teaching. Surgical oncology and HPB fellows and ultimately patients may benefit from increased clinical and didactic palliative care training.

The aim of this study was to evaluate the efficacy of using matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9)-cleavable ratiometric activatable cell-penetrating peptides (RACPPs) conjugated to Cy5 and Cy7 fluorophores to accurately label pancreatic cancer for fluorescence-guided surgery (FGS) in an orthotopic mouse model. ⋯ RACPPs can accurately and effectively label pancreatic cancer for effective FGS, resulting in better postresection outcomes than for WLR surgery.
