The Clinical and Surgical Characteristics of Parotid Tumors with Parapharyngeal Space Involvement-A Multicenter Experience of the Polish Salivary Network.

Parotid gland tumors (PGTs) with parapharyngeal space (PPS) involvement have a specific clinical course and they can be a great challenge for surgeons, especially due to more difficult approaches and the risk of serious complications. The aim of this study is to present the characteristics of PGTs with PPS involvement. : Retrospective, multicenter analysis of 1954 primary PGTs from 5 years (2017-2021) was performed.

Rationale for Increasing Oncological Vigilance in Relation to Clinical Findings in Accessory Parotid Gland-Observations Based on 2192 Cases of the Polish Salivary Network Database.

This gives rise to the hypothesis, mirrored in clinical observations, that the representation of tumours is different than in the rest of the gland. The aim of the study was to analyse the epidemiological and histological differences of parotid tumours located in regions I-V, with particular emphasis on the distinctiveness of region V.

Altered Expression of miRNAs Is Related to Larynx Cancer TNM Stage and Patients' Smoking Status.

It has been reported that microRNAs (miRNAs) are responsible for acquiring all the hallmarks of cancer cells, as well as have a significant impact on the clinical management of cancers at every stage, including prognosis, remission, relapse, and metastasis. In this study, we investigated the association of miR-29a-3p, miR-202-3p, miR-3713, miR-4768-3p, and miR-548aa expression with clinicopathologic features in patients suffering from laryngeal cancer (LC) and determined the potential role of studied miRNAs in the progression of LC. The study group consisted of 48 patients with untreated primary tumors of head and neck cancer localized in the larynx.

Evaluation of polymorphisms in microRNA biosynthesis genes and risk of laryngeal cancer in the Polish population.

MicroRNAs are the largest group of short regulatory RNAs. They regulate genes participating in many physiological and pathological processes. The role of micro RNAs in cancer development is also considerable.

Association of Polymorphic Variants of miRNA Processing Genes with Larynx Cancer Risk in a Polish Population.

Laryngeal cancer (LC) is one of the most prevalent types of head and neck cancer. An increasing interest has been focused on the role of microRNA (miRNAs) in LC development. The study group consisted of 135 larynx cancer patients and 170 cancer-free individuals.

Non-epithelial neoplasms of the larynx and hypopharynx - 12 - years of experience.

Objective: The non-epithelial neoplasms of larynx and hypopharynx are of rare incidence but may originate from various histological tissues. These effect in the difficulty of final diagnosis and often delay the proper treatment.
