Striated duct adenoma: The cytological description of a rare entity.

Introduction: Striated duct adenoma is a benign salivary gland tumour recently recognized by the World Health Organization. To date, no report has described the cytological features of this entity.

Materials And Methods: We report the case of a 60-year-old woman with a tumour in the right parotid gland with a diameter greater than 2.

Durable complete remission with local therapies after neoadjuvant and adjuvant nivolumab in recurrent/metastatic head and neck cancer.

Up to 10-15% of patients with first-line recurrent/metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) present with platinum-refractory disease. The anti-PD1 nivolumab is the first therapeutic option in this setting achieving a 19.2% objective response rate and a 7.

Safety and preliminary activity of pembrolizumab-carboplatin-paclitaxel in heavily pretreated and/or fragile patients with PDL1-positive recurrent/metastatic head and neck cancer.

Novel chemo-immunotherapy (chemo-IO) combinations should be evaluated, which may be suitable for cisplatin-unfit or fluoropyrimide-ineligible patients with recurrent or metastatic squamous cell carcinoma of head and neck (R/M SCCHN) to guarantee higher and deeper responses than IO alone. The aim of the present study was to review our experience using pembrolizumab-carboplatin-paclitaxel (pembro + CP) in patients with R/M SCCHN. This was a retrospective study of patients with R/M SCCHN who received pembro + CP in any-line via a compassionate-use program.

Durable benefit and change in TCR clonality with nivolumab in a Lynch syndrome-associated glioma.

Germline replication-repair deficient (gRRD) gliomas are exceptional events, and only a few of them have been treated with immune checkpoint inhibitors (ICIs). Contrary to sporadic gliomas, where ICIs have failed to show any objective benefit, the very few patients with gRRD gliomas treated with ICIs to date seem to benefit from programmed-death-1 (PD-1) inhibitors, such as nivolumab or pembrolizumab, either in terms of durable responses or in terms of survival. T-cell immunohistochemistry (IHC) and T-cell receptor (TCR) repertoire using high-throughput next-generation sequencing (NGS) with the Oncomine TCR-Beta-SR assay (Thermo Fisher Scientific) were analyzed in pre- and post-nivolumab tumor biopsies obtained from a patient with a Lynch syndrome-associated glioma due to a germline pathogenic mutation.

Major pathological response and durable locoregional control after neoadjuvant pembrolizumab-carboplatin-paclitaxel in head and neck cancer.

Head and neck cancers are increasingly being diagnosed in elderly patients, where standard curative-intent, therapeutic options are often too aggressive for frail, malnourished and heavily comorbid patients. Since the incorporation of immune checkpoint inhibitors (ICIs) a few small studies have reported promising safety and efficacy with ICIs in the neoadjuvant locally-advaced setting. We present the case of an elderly, frail and comorbid patient, with a high-PDL1 expressing and very locally-advanced unresectable oral cavity cancer, that was treated with the combination of pembrolizumab and weekly carboplatin and paclitaxel, achieving a major pathological response, that permitted to de-escalate adjuvant therapy after surgery and is free of locoregional relapse 7 months after surgery.
