Immunohistochemical characterisation of the immune landscape in primary uveal melanoma and liver metastases.

Background: The immune landscape of uveal melanoma liver metastases (UMLM) has not been sufficiently studied.

Methods: Immune cell infiltrates (ICIs), PD-1 and PD-L1 were characterised in 62 UMLM and 28 primary uveal melanomas (PUM). ICI, PD-1 and PD-L1 were scored as: (1) % tumoral area occupied by tumour-infiltrating lymphocytes or macrophages (TILs, TIMs) and (2) % perTumoral (perT) area.

Dissociated Responses in Patients with Metastatic Solid Tumors Treated with Immunotherapy.

Background: Immune checkpoint inhibitors have been demonstrated to improve overall survival. Atypical patterns of response have been reported, including dissociated response (DR). We evaluated the prevalence of DR.

Efficacy and safety of immune checkpoint inhibitors in elderly patients (≥70 years) with squamous cell carcinoma of the head and neck.

Background: Recent meta-analysis showed that immune checkpoint inhibitors (ICIs) have comparable activity between younger and older patients. However, little is known about efficacy and safety of ICI in elderly patients with relapsed/metastatic squamous cell carcinoma of the head and neck (R/M SCCHN). The aim of this study is to compare the efficacy of ICI for patients aged ≥70 y to that for younger patients, while taking into account potential confounding factors.

Adult parameningial alveolar rhabdomyosarcoma: Case report and literature review.

Alveolar rhabdomyosarcoma (ARMS) represents the most common childhood soft tissue sarcoma, but they are rarely seen among adults. Most of the protocols for adults are adapted from pediatric protocols. Here we report a case of a 53-year-old woman diagnosed with a nasal alveolar rhabdomyosarcoma, stage IV at diagnosis, treated by chemotherapy (a regimen inspired from the pediatric protocole pEpSSG RMS 2005) which led to partial response followed by chemo-radiotherapy.
