Assessment of oral disease burden among head and neck cancer patients in the Merseyside region.

Introduction Head and neck cancer (HANC) significantly impacts the oral cavity and dental health issues may complicate cancer treatment and post-treatment quality of life. Pre-treatment dental evaluation is critical for identifying and managing existing oral health problems. However, limited literature exists on the dental health status of patients at the time of HANC diagnosis.

Sequential Analysis of cfDNA Reveals Clonal Evolution in Patients with Neuroblastoma Receiving ALK-Targeted Therapy.

Purpose: The study of cell-free DNA (cfDNA) enables sequential analysis of tumor cell-specific genetic alterations in patients with neuroblastoma.

Experimental Design: Eighteen patients with relapsing neuroblastoma having received lorlatinib, a third-generation ALK inhibitor, were identified (SACHA national registry and/or in the institution). cfDNA was analyzed at relapse for nine patients and sequentially for five patients (blood/bone marrow plasma) by performing whole-genome sequencing library construction followed by ALK-targeted ddPCR of the hotspot mutations [F1174L, R1275Q, and I1170N; variant allele fraction (VAF) detection limit 0.

Extracellular matrix educates an immunoregulatory tumor macrophage phenotype found in ovarian cancer metastasis.

Recent studies have shown that the tumor extracellular matrix (ECM) associates with immunosuppression, and that targeting the ECM can improve immune infiltration and responsiveness to immunotherapy. A question that remains unresolved is whether the ECM directly educates the immune phenotypes seen in tumors. Here, we identify a tumor-associated macrophage (TAM) population associated with poor prognosis, interruption of the cancer immunity cycle, and tumor ECM composition.

The prosthodontic management of the maxillectomy patient.

Ablative defects of the maxilla caused by malignant tumours create a multitude of difficulties for patients and the clinical teams looking after them. Tumours of the maxilla, while relatively uncommon, require significant multi-disciplinary involvement due to their effects on the aesthetic, functional and psychological aspects of the patients involved. Patients with these tumours have worse survival than other head and neck sites, with a propensity to local and regional recurrence.
