Beyond making treatments less effective and more toxic, malnutrition can reduce a patient’s functional abilities and quality of life while increasing the risk of complications. For many decades, however, the surprisingly common and largely unresolved phenomenon of malnutrition in patients with cancer was seen as an inevitability.</p><p>Jann Arends, MD, a gastroenterologist, hematologist, and medical oncologist at the University of Freiburg in Germany, says that weight loss and emaciation were once taken for granted as a standard feature of intractable cancers. “Most cancers would not respond to even aggressive anticancer treatments, and weight loss was seen as a harbinger of death and not as a condition requiring supportive care,” Dr Arends says.</p><p>That mindset further solidified, he says, when clinical trials testing routine artificial nutrition (delivered via feeding tubes or intravenous lines) yielded no discernable benefits for patients but higher complication rates than oral feeding. In response, the American Society for Parenteral and Enteral Nutrition recommended not using artificial nutrition to treat patients with cancer and thus furthered what Dr Arends calls “nutritional nihilism in an age of only rare oncological success.”</p><p>As cancer treatment successes have multiplied during the past 15 years, however, more research has helped to change recommendations, refine the benefits and limitations of nutritional care in patients, and provide better estimates of just how common malnutrition can be.</p><p>One eye-opening 2014 study of approximately 1900 patients with cancer in 154 hospitals throughout France found that 39% were malnourished, including more than 60% of patients diagnosed with pancreatic, esophageal, or stomach cancer.<span><sup>1</sup></span></p><p>Although malnutrition rates tend to be higher in hospitalized patients, the condition also is common even in newly diagnosed patients. In 2017, the Prevalence of Malnutrition in Oncology study in Italy sought to get a better view of the nutritional status of adult patients at their first visit to a medical oncology center after being diagnosed with a solid tumor.<span><sup>2</sup></span> Conducted at 22 centers across the country, the observational study enrolled nearly 2000 patients. Oncologists used several scales, including the Mini Nutritional Assessment, to assess the patients for signs of nutritional impairment.</p><p>Collectively, they found that 51% of the patients had a nutritional impairment, 9% were overtly malnourished, and 43% were at risk for malnutrition. More than 40% had anorexia, or an abnormal loss of appetite, while 64% had lost weight during the previous 6 months.

The risk can be further characterized according to tumor type: A donor’s brain tumor that has metastasized, for example, would pose a considerably bigger danger than a far more treatable thyroid tumor.&lt;/p&gt;&lt;p&gt;The most significant cancer-related risk for organ transplant recipients, however, is associated with the very immunosuppressive medications that are required to prevent rejection of the organs but also can render the immune system less able to identify and kill tumor cells or battle cancer-linked infections. “The patients are so heavily immunosuppressed as part of the transplant protocol that the host versus the virus mechani","PeriodicalId":9410,"journal":{"name":"Cancer Cytopathology","volume":"133 2","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cncy.22932","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143000667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
