In vivo and ex vivo confocal microscopy for the evaluation of surgical margins of melanoma.

We report the first series of melanomas (MMs) where the surgical margins were evaluated both by ex vivo confocal microscopy (EVCM) and in vivo reflectance confocal microscopy (RCM). We evaluated the surgical margins of 42 cutaneous MMs of lentigo maligna/lentigo maligna melanoma type and 2 mucosal MMs with EVCM. Cutaneous MMs also underwent RCM mapping.

Supporting clinical decision making in advanced melanoma by preclinical testing in personalized immune-humanized xenograft mouse models.

Background: The mouse strains usually used to generate patient-derived xenografts (PDXs) are immunocompromised, rendering them unsuitable for immunotherapy studies. Here we assessed the value of immune-PDX mouse models for predicting responses to anti-PD-1 checkpoint inhibitor therapy in patients.

Patients And Methods: Melanoma biopsies contained in a retrospective biobank were transplanted into NOG mice or NOG mice expressing interleukin 2 (hIL2-NOG mice).

Short-term outcome of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy used as treatment of colo-rectal carcinomatosis: a multicentric study.

The aim of this study is to assess the morbidity and mortality related to cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with colo-rectal carcinomatosis. A retrospective multi-institutional study from seven Italian Centers was performed. One hundred and seventy-two patients, submitted to cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) to treat carcinomatosis of colorectal origin, were recorded.

Mitochondrial protein enriched extracellular vesicles discovered in human melanoma tissues can be detected in patient plasma.

Extracellular vesicles (EVs), including exosomes and microvesicles, are secreted from all cells, and convey messages between cells in health and disease. However, the diversity of EV subpopulations is only beginning to be explored. Since EVs have been implicated in tumour microenvironmental communication, we started to determine the diversity of EVs specifically in this tissue.
