In light of the recurring global health crises, there is an urgent need to understand the impact of various factors on patient health, especially for the most vulnerable groups such as cancer patients. Since the emergence of the COVID-19 pandemic, approximately 760 million cases of SARS-CoV-2 infection have been reported, resulting in a significant number of deaths and ongoing health challenges. One of those challenges is post-COVID-19 syndrome, which particularly affects patients with weakened immune systems due to illnesses and treatments. Studies suggest that nutritional status significantly impacts the likelihood of contracting and recovering from COVID-19 in these patients. This article reviews a multicenter study aimed at exploring the relationship between the nutritional status of cancer patients and rates of coronavirus infection, in addition to post-COVID-19 syndrome rates. Through a thorough analysis of the methods and results, the article seeks to offer new insights that contribute to improving healthcare strategies and nutritional interventions during epidemics.
The Negative Effects of SARS-CoV-2 Infection on Cancer Patients
Since 2019, approximately 760 million cases of SARS-CoV-2 infection have been reported worldwide, causing numerous deaths and health challenges, especially among vulnerable groups such as cancer patients. These patients are often in a state of immunosuppression due to their illness and the treatments they receive, such as chemotherapy and radiotherapy, which complicates such infections. Studies have shown that cancer patients suffering from malnutrition are at increased risk of contracting the novel coronavirus, which exacerbates the severity of symptoms and the speed of complications. Researching how nutritional status affects infection outcomes post-SARS-CoV-2 infection is vital in the context of prevention and health risk management. For example, a study at a hospital in Brazil found that the malnutrition rate among cancer patients reached about 34.6%, a high rate compared to the general population of Brazil.
These alarming statistics necessitate more effective strategies to address the effects of COVID-19 on cancer patients, as nutritional status is considered a crucial factor in strengthening the immune system and improving recovery capacity. It is also important to note that food safety and quantity play a fundamental role in the health of these patients, especially during the pandemic or in the face of new viral strains. Therefore, it is essential to study nutritional factors and their impact on improving treatment outcomes and reducing health risks resulting from COVID-19 infection.
The Relationship between Nutritional Status and SARS-CoV-2 Infection
Research indicates that nutritional status plays a critical role in how the body responds to infections, including COVID-19. Evidence shows that patients suffering from malnutrition or low body mass index (BMI) may be more susceptible to the virus as well as its complications. In this context, a recent study utilized the Nutritional Risk Screening tool NRS-2002, which has proven effective in assessing the risk of malnutrition among cancer patients. Research indicates that a high risk of malnutrition is associated with increased severity of symptoms and negative outcomes post-SARS-CoV-2 infection, with the rate of patients experiencing post-COVID-19 syndrome in the high-risk group around 32.7% compared to 19.5% in the low-risk group. This statistical difference highlights the impact of nutritional status as a determining factor for infection outcomes among cancer patients.
Studies show that improving nutritional status can enhance the body’s response to infections and improve the overall quality of life for patients. For example, vitamins like vitamin D, which are essential for boosting immunity, have been linked to lower rates of infections and faster recovery. This underscores the importance of designing specific nutritional programs targeting cancer patients, which may reduce the likelihood of exposure to infections and their negative effects.
Strategies
Nutrition for Individuals with Cancer During the COVID-19 Pandemic

Cancer patients are at increased risk of infectious diseases, including COVID-19, due to compromised immune systems. While understanding how nutritional status affects health risks is crucial, a lack of research linking nutritional status to the risk of cancer patients contracting SARS-CoV-2 has been noted. To address this research gap, a study targeting cancer patients was conducted across several centers in China, aiming to examine the impact of nutritional status among cancer patients on the risk of contracting SARS-CoV-2 and post-COVID-19 syndrome.
The study was conducted across four provinces in China, where data was collected from cancer patients at four different hospitals, and the results yielded valuable insights that may help improve targeted prevention and treatment strategies for cancer patients, especially in the future with the potential emergence of multiple variants of COVID-19. This research aims to explore the relationship between nutritional status and patient health, hoping to provide scientific evidence to guide clinical practices and develop nutritional interventions to improve outcomes during and after the COVID-19 pandemic.
Design
Study and Data Collection Method
This study was designed as a cross-sectional multicenter study, conducted from December 2022 to June 2023 in four leading hospitals across different provinces in China. The hospitals were selected based on their size and the quality of services provided. The process included selecting patients willing to participate and then collecting accurate information about their health and nutritional status. The study utilized a convenient sampling method, with a sequential extraction of households and study periods.
Comprehensive medical questionnaires were administered covering demographic aspects, cancer types, and medications used. Tools such as NRS2002 were employed to assess nutritional risks, allowing for the precise identification of patients at specific nutritional risk. This included measurements of weight, height, body mass index, and other relevant factors. A team of specialists was formed to evaluate the nutritional status and COVID-19 infection criteria among patients, ensuring the use of accurate and clinically appropriate standards.
Results and Data Analysis
The results showed that we collected data from 1,210 patients, of which 834 patients met the study criteria. Analyses indicated that approximately 58.8% of cancer patients had contracted SARS-CoV-2 prior to sampling. There were clear differences between patients at risk of malnutrition and those with good nutrition, with a higher infection rate observed among the malnourished group. Additionally, analyses revealed that age, gender, and type of treatment all influenced the likelihood of infection.
This research underscores the urgent need to recognize nutritional status as a fundamental factor in pandemic prevention programs, particularly for vulnerable patients such as cancer patients. Findings indicate, for example, that male and older cancer patients were at a higher risk of contracting COVID-19. Analytical indicators benefited from a multivariable model that allowed for the identification of independent effects of age, gender, and type of cancer on the incidence of infection and post-COVID-19 syndrome.
Future Recommendations and Clinical Considerations
Based on the study results, several important recommendations can be drawn. There is an urgent need to develop programs aimed at improving the nutritional status of cancer patients. These programs should focus on equipping patients with the necessary information and resources to enhance their nutrition, thereby giving them a better chance to resist infections.

Studies indicate that nutritional status plays a crucial role in recovery from illnesses, especially among cancer patients who have suffered from the effects of COVID-19 infection. Data revealed that 12.4% of cancer patients experienced post-COVID-19 syndrome, with research indicating variability in this percentage based on several factors such as gender, education level, and type of cancer. For example, men were more likely to develop post-COVID-19 syndrome compared to women, with a difference of 1.78 in the odds ratio. The study also showed that breast cancer patients were more susceptible to developing the syndrome compared to those with other cancers. For patients who underwent radiation therapy only, there was a lower likelihood of developing the syndrome.
The Nutrition Risk Score (NRS) is an important measure for understanding the nutritional status of patients. According to the study, patients scoring less than 3 on the NRS had a COVID-19 infection rate of 58.5%. In contrast, individuals scoring 3 or more showed slightly higher infection rates. However, there was no significant increase in the risk of infection for those scoring above 3, suggesting that nutritional status may not necessarily be linked to an increased risk of contracting COVID-19.
Common Symptoms of Post-COVID-19 Syndrome and Their Relationship to Nutritional Status
Among 490 cancer patients with COVID-19, the study showed that 21% of them had symptoms associated with post-COVID-19 syndrome. The most common symptoms were fatigue and chronic cough at 44.7% and 43.7%, respectively. Furthermore, 31.1% of patients reported sleep disturbances, and 20.4% suffered from musculoskeletal pain. Changes in the sense of smell or taste, chest pain, and loss of appetite were similarly reported at around 15%.
Inferences from the analyses also indicated that patients with NRS scores below 3 had a post-COVID-19 disease infection rate of 19.5%, while the rate increased to 32.7% among individuals scoring 3 or higher. Previous research supports that malnutrition can hinder the body’s immune response and prolong recovery duration, which explains the prevalence of complex symptoms among cancer patients after infection with COVID-19.
Implications of Study Findings on Clinical Care for Cancer Patients
The study findings reveal the importance of assessing and managing nutritional status in the care of cancer patients, particularly in the context of the ongoing COVID-19 pandemic. Early identification of patients at high nutritional risk is a critical step toward guiding appropriate interventions, such as nutritional supplements and dietary guidelines, which can help reduce the risk of developing post-COVID-19 syndrome. This approach can improve overall outcomes and reduce mortality rates.
The findings also suggest a complex relationship between demographic and clinical factors and COVID-19 outcomes in cancer patients. For instance, patients with higher education levels were found to be more susceptible to COVID-19, reflecting different social behaviors or occupational exposures. Women with breast cancer were more likely to develop the syndrome, necessitating the need for risk stratification and management strategies tailored to individual contexts.
