Cancer patients may have been more adversely affected during the COVID-19 Pandemic due to their receipt of immunosuppressive treatments, higher burden of comorbidities, and greater nutritional vulnerability compared to the general population. The aim of our study is to identify potential measures by detecting changes in the nutritional statuses of patients with an oncological diagnosis who presented to our hospital during the COVID-19 pandemic, using the globally accepted NRS-2002 questionnaire. Materials and Method: Our study included 324 patients diagnosed with malignancy who applied to the outpatient clinic of Gaziantep University, \u015eahinbey Training and Research Hospital, Gaziantep\/T\u00fcrkiye, between December 2021 and January 2022 or were hospitalized in the service. Patients included in the study were evaluated in terms of clinical\u2013demographic information and COVID-19-related characteristics using a sociodemographic data form we developed, and then the NRS-2002 questionnaire was administered. Results: Our study included 324 patients. Overall, 49.07% (159 patients) of the patients were male, and 50.93% (165 patients) were female. A total of 20.37% of our patients (66 patients) had COVID-19 disease. While those living with their families constituted 96.91% of the patients, at least one of the family members of 36.42% of the patients had COVID-19 disease. While 76.23% (247 patients) of the patients were vaccinated, 23.77% (77 patients) were not vaccinated. When NRS analyses were examined according to the type of malignancy, a statistically significant difference was found between NRS analyses according to the type of diagnosis. When NRS analyses were examined according to the stages of the diseases, it was determined that stage 4 patients were in the risk group in terms of nutrition. When NRS analyses according to age were examined, it was determined that patients over the age of 65 were in the risk group in terms of nutrition. When NRS analyses by gender were examined, it was found that male patients were in the risk group in terms of nutrition. When the NRS analyses were examined according to whether or not radiotherapy was administered, it was determined that the patients who received radiotherapy were in the risk group in terms of nutrition. Contrary to the literature, no statistically significant difference was found according to whether or not chemotherapy was administered. Conclusions: According to NRS analysis, no statistically significant differences were found in terms of nutritional status according to COVID-19 transmission and vaccination status. When NRS analyses were examined according to the delay of treatment during the pandemic period, it was found that patients who postponed treatment were in the risk group in terms of nutrition, while patients who did not postpone treatment were mostly in the follow-up group. In multivariable analyses, however, no independent relationship was identified between this parameter and NRS-2002 risk.<\/jats:p>","DOI":"10.3390\/medicina62081584","type":"journal-article","created":{"date-parts":[[2026,8,18]],"date-time":"2026-08-18T10:22:52Z","timestamp":1787048572000},"page":"1584","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Nutritional Status of Cancer Patients During the COVID-19 Pandemic"],"prefix":"10.3390","volume":"62","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7001-3945","authenticated-orcid":false,"given":"Ayd\u0131n","family":"Aytekin","sequence":"first","affiliation":[{"name":"Division of Medical Oncology, Department of Internal Medicine, Faculty of Medicine, Gaziantep University, 27310 Gaziantep, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00dcmit","family":"Bilge","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Faculty of Medicine, Gaziantep University, 27310 Gaziantep, T\u00fcrkiye"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,18]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (WHO) (2020).
