Background: The conventional method of drug development in oncology typically progresses through phase I, phase II and randomized phase III trials. Nevertheless, some recent drug approvals for head and neck cancer (HNC) relied on findings from single-arm phase II trials. This underscores the significance of disease-specific phase I trials as a crucial step in exploring new drugs for HNC patients.

This study investigated TIL distribution, its prognostic value, and PD-L1 expression in metastatic and matched primary tumors (PTs). Specimens from 550 pan-cancer patients of the SHIVA01 trial (NCT01771458) with available metastatic biopsy and 111 matched PTs were evaluated for TILs and PD-L1.

Introduction: Poorly differentiated primary sarcomatoid parotid malignancies are extremely rare. These tumors have not been consistently studied by morphology, immunohistochemistry, or molecular techniques.
Case Presentation: We report three unusual cases of parotid gland poorly-differentiated sarcomatoid malignancy investigated by fine-needle aspiration and studied histologically, by immunohistochemistry and molecular investigations.
Purpose: To evaluate tipapkinogene sovacivec (TG4001), a viral immunotherapeutic vaccine expressing human papillomavirus (HPV)16 E6/E7 non-oncogenic proteins and IL-2, in combination with avelumab in HPV16+ cancer patients.
Patients And Methods: In this open-label, phase Ib/II, multicenter study, HPV16+ advanced cancer patients received subcutaneous TG4001 at two dose levels (DL) in phase Ib and at the recommended phase II dose (RP2D) in phase II weekly for 6 weeks, then every 2 weeks (q2Wk) until 6 months, thereafter every 12 weeks, in combination with avelumab q2Wk starting from day 8. Exploratory end-points included immunomonitoring from sequential tumour and blood samples.
Concurrent chemoradiotherapy (CRT) with blockade of the PD-1 pathway may enhance immune-mediated tumor control through increased phagocytosis, cell death, and antigen presentation. The NiCOL phase 1 trial (NCT03298893) is designed to determine the safety/tolerance profile and the recommended phase-II dose of nivolumab with and following concurrent CRT in 16 women with locally advanced cervical cancer. Secondary endpoints include objective response rate (ORR), progression free survival (PFS), disease free survival, and immune correlates of response.

Recent Findings: Limited treatment options exist in HNSCC. Cetuximab, an mAb targeting epidermal growth factor receptor, and the PD-1 inhibitors nivolumab and pembrolizumab, are the only drugs that improved overall survival in the recurrent and/or metastatic setting.
Background: Data on the role of the microbiota in cancer have accumulated in recent years, with particular interest in intratumoral bacteria. Previous results have shown that the composition of intratumoral microbiome is different depending on the type of primary tumour and that bacteria from the primary tumour could migrate to metastatic sites.
Methods: Seventy-nine patients with breast, lung, or colorectal cancer and available biopsy samples from lymph node, lung, or liver site, treated in the SHIVA01 trial were analysed.
Immunotherapy has made a breakthrough in medical oncology with the approval of several immune checkpoint inhibitors in clinical routine, improving overall survival of advanced cancer patients with refractory disease. However only a minority of patients experience a durable response with these agents, which has led to the development of combination strategies and novel immunotherapy drugs to further counteract tumor immune escape. Epigenetic regulations can be altered in oncogenesis, favoring tumor progression.

We aimed to rank the level of evidence of recurrent actionable molecular alterations in head and neck squamous cell carcinoma (HNSCC) on the basis of the European Society for Medical Oncology (ESMO) Scale for Clinical Actionability of Molecular Targets (ESCAT) to help the clinicians prioritize treatment. We identified actionable alterations in 33 genes.

Objective We investigated the dose-limiting toxicities (DLTs), maximum tolerated dose, pharmacokinetics, and preliminary efficacy of the combination of copanlisib, an intravenous, pan-class I PI3K inhibitor, with the anti-EGFR monoclonal antibody cetuximab in recurrent and/or metastatic HNSCC patients in a phase I dose-escalation trial. Patients and methods Copanlisib was given intravenously on days 1, 8, and 15 of 28-day cycles at the dose of 45 mg and 30 mg, in combination with standard doses of weekly cetuximab (400 mg/m loading dose followed by 250 mg/m on days 8, 15, and 22, and weekly thereafter).

Nivolumab as single agent is approved regardless of PD-L1 expression for recurrent and/or metastatic patients following progression within 6 months of platinum therapy administered either in the first line recurrent setting, or concomitantly with radiotherapy.
View Article and Find Full Text PDFCetuximab, a monoclonal antibody targeting the epidermal growth factor receptor (EGFR) in combination with platinum-based chemotherapy has been for the decade standard of care for the treatment of head and neck squamous cell carcinomas (HNSCC) patients in the first-line recurrent and/or metastatic setting. The KEYNOTE-048 trial published last year established a new paradigm in this setting with the demonstration that immunotherapy should be given either alone or in combination with chemotherapy. Indeed, pembrolizumab, an antiprogrammed cell death 1 (PD-1) immune checkpoint inhibitor, improved overall survival as compared to the EXTREME regimen in patients expressing PD-L1 in the tumor microenvironment, which represents a large majority of the patient population.

Recently, benefit in overall survival was reported in metastatic castration-sensitive prostate cancer also, and an extension of indication has been granted. Abiraterone is seldom associated with liver toxicity.

Most of cervical cancers are associated with the human papillomavirus (HPV) infection that leads to viral antigens production, supporting the development of immunotherapy in cervical cancer. : Here we report the pharmacologic properties, clinical efficacy, and safety profile of pembrolizumab, an IgG4-kappa humanized monoclonal antibody against the programmed cell death protein 1 (PD-1) receptor, for the treatment of cervical cancer.

Methods: Retrospective nonrandomized analysis of an inception cohort of 191 patients. Platinum salt and 5-fluorouracil were used in all patients.
Background: Anti-programmed cell death 1 (PD-1) and anti-programmed cell death ligand 1 (PD-L1) antibodies are novel immunotherapies for cancer that can induce immune-related adverse events (irAEs). These adverse events can involve all organs, including the haemopoietic system. Thus far, haematological irAEs (haem-irAEs) have not been extensively characterised.

Cholangiocarcinoma is a rare malignancy carrying a poor prognosis. Most patients are diagnosed with advanced-stage disease and are then ineligible for surgical resection, which is the only potentially curative therapeutic modality. The aim of this article is to provide an up-to-date review of medical management of patients with cholangiocarcinoma.
