Gene expression levels associated with impaired immune response and increased proliferation could serve as biomarkers for women following cervical cancer screening programmes.

Human papilloma virus (HPV) infections vary in their oncogenic potential, and whether an infection progresses to cervical intraepithelial neoplasia (CIN) also depends on the immune response. Therefore, the aim of the present study was to explore biomarkers related to the immune system and cell proliferation, in combination with HPV classified as having high (HOP) or low oncogenic potential (LOP), that can possibly guide a more accurate identification of women following cervical cancer screening programmes in need for immediate follow-up with a biopsy. A next-generation sequencing transcriptomic immune profile analysis applied to 28 persistent CIN3 lesions and 14 normal biopsies identified four genes, the immune markers and and the tumour markers and , as possible markers for differentiating between CIN3 and normal tissue.

[A case report of organ-preserving surgical treatment for large pleomorphic adenoma of the larynx].

Tumors of the salivary glands account for no more than 5% of all neoplasms of the head and neck. About 70% of all benign neoplasms of the salivary glands are pleomorphic. One of the rare localizations of pleomorphic adenoma is the larynx.

Extracellular vesicles as a potential source of tumor-derived DNA in advanced pancreatic cancer.

Tumor-derived extracellular vesicles (EVs) are reported to contain nucleic acids, including DNA. Several studies have highlighted the potential of EV-derived DNA (evDNA) as a circulating biomarker, even demonstrating that evDNA can outperform cell-free DNA (cfDNA) in terms of sensitivity. Here, we evaluated EVs as a potential source of tumor-derived DNA in patients with advanced pancreatic cancer.

Monitoring of circulating tumour DNA in advanced pancreatic ductal adenocarcinoma predicts clinical outcome and reveals disease progression earlier than radiological imaging.

Pancreatic ductal adenocarcinoma (PDAC) is a lethal disease with a need for better tools to guide treatment selection and follow-up. The aim of this prospective study was to investigate the prognostic value and treatment monitoring potential of longitudinal circulating tumour DNA (ctDNA) measurements in patients with advanced PDAC undergoing palliative chemotherapy. Using KRAS peptide nucleic acid clamp-PCR, we measured ctDNA levels in plasma samples obtained at baseline and every 4 weeks during chemotherapy from 81 patients with locally advanced and metastatic PDAC.

[COVID-19 associated sino-orbital mucormycosis].

Objective: To analyze the dynamics of symptoms in patients with COVID-19 associated sino-orbital mucormycosis.

Material And Methods: We describe a series of 13 patients with COVID-19 associated sino-orbital mucormycosis aged 43 to 80 years diagnosed from August to October 2021. All of the patients had a severe disease and required noninvasive ventilation or intubation and administration of dexamethasone.
