The main factor contributing to the development of cachexia is the ongoing inflammatory process. The gene associated with the development of the inflammatory response is ITGAM. Therefore, the aim of the study was to assess the relationship between a single nucleotide polymorphism (SNP)-323G&gt;A of the ITGAM gene and the occurrence of nutritional disorders in patients undergoing radiotherapy (RT) due to head and neck cancers (HNC). Methods: The study involved 71 patients with HNC treated with intensity-modulated radiotherapy (IMRT). SNP analysis of the ITGAM gene (-323G&gt;A) was performed using commercial molecular probes and Real-Time PCR. Results: The presence of the A allele of the ITGAM gene significantly (over 14-fold) reduced the risk of severe disturbances in nutritional status assessed according to the subjective global assessment (SGA) scale (odds ratio (OR) = 0.07; p = 0.0213). The GG genotype of this gene was associated with an over three-fold higher risk of shortened overall survival (OR = 3.01; p = 0.0376). Conclusions: Determination of the SNP (-323G&gt;A) of the ITGAM gene may prove to be a useful marker in the assessment of the risk of nutritional disorders in patients with HNC undergoing RT.<\/jats:p>","DOI":"10.3390\/jcm9124041","type":"journal-article","created":{"date-parts":[[2020,12,14]],"date-time":"2020-12-14T22:30:52Z","timestamp":1607985052000},"page":"4041","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Polymorphism of The Regulatory Region of the ITGAM Gene (-323G&gt;A) as a Novel Predictor of a Poor Nutritional Status in Head and Neck Cancer Patients Subjected to Intensity-Modulated Radiation Therapy"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4040-0450","authenticated-orcid":false,"given":"Marcin","family":"Mazurek","sequence":"first","affiliation":[{"name":"Department of Human Physiology, Medical University of Lublin, 20-059 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7399-8340","authenticated-orcid":false,"given":"Rados\u0142aw","family":"Mlak","sequence":"additional","affiliation":[{"name":"Department of Human Physiology, Medical University of Lublin, 20-059 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iwona","family":"Homa-Mlak","sequence":"additional","affiliation":[{"name":"Department of Human Physiology, Medical University of Lublin, 20-059 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomasz","family":"Powr\u00f3zek","sequence":"additional","affiliation":[{"name":"Department of Human Physiology, Medical University of Lublin, 20-059 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Brzozowska","sequence":"additional","affiliation":[{"name":"II Department of Radiotherapy, Center of Oncology of the Lublin Region St. John of Dukla, 20-059 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pawe\u0142","family":"Go\u0142\u0119biowski","sequence":"additional","affiliation":[{"name":"II Department of Radiotherapy, Center of Oncology of the Lublin Region St. John of Dukla, 20-059 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teresa","family":"Ma\u0142ecka-Massalska","sequence":"additional","affiliation":[{"name":"Department of Human Physiology, Medical University of Lublin, 20-059 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"123","DOI":"10.1016\/j.coms.2014.01.001","article-title":"Epidemiologic trends in head and neck cancer and aids in diagnosis","volume":"26","author":"Vigneswaran","year":"2014","journal-title":"Oral Maxillofac.
