High-grade Gastroenteropancreatic Neuroendocrine neoplasms (H-NENs) comprehend well-differentiated tumors (NET G3) and poorly differentiated carcinomas (NEC) with proliferative activity indexes as mitotic count (MC) >20 mitoses/10 HPF and Ki-67 >20%. At present, no specific therapy for H-NENs exists and the several evidences of microenvironment involvement in their pathogenesis pave the way for tailored therapies. Forty-five consecutive cases, with available information about T-cell, immune, and non-immune markers, from surgical pathology and clinical databases of 2 Italian institutions were immunostained for Arginase, CD33, CD163 and CD66 myeloid markers.

- The study investigated the effects of a sudden shift to digital pathology during the COVID-19 pandemic on diagnostic accuracy and pathologist perceptions.
- It involved 17 participants who analyzed archived test cases and completed a survey, with results compared to traditional microscopy methods.
- The findings showed a 9% overall error rate, suggesting that while transition duration may not impact performance, senior pathologists faced challenges adapting to digital methods, potentially leading to discrepancies in diagnoses.*
The antidiabetic drug metformin displays anticancer properties in several neoplasms. In pituitary NETs, aryl hydrocarbon receptor-interacting protein (AIP) is up-regulated by the somatostatin analog octreotide. Metformin inhibited QGP-1 cell proliferation in a dose- and time-dependent manner, at concentrations similar to those achievable in treated patients (-31 ± 12%, p < 0.

No studies have yet compared the efficacy and safety of the MBM devices commercially available: Duette™ (CookMedical) and Captivator™ (BostonScientific). Our aim is to compare the two devices.

Primary cancers responsible for penile metastases usually occur in prostate and rectum and are often associated with disseminated malignancy and poor prognosis.
Case Description: A 66-year-old man was diagnosed with adenocarcinoma of the tail of the pancreas after the onset of thrombosis of the dorsal vein of the penis; pubis ultrasound and total body computed tomography scan were negative for metastases at other sites.
