Use this handout to measure your hunger level on a scale of 1 to It performs well compared to other tools and is therefore used to validate the other screening methods The PG-SGA closely correlates with patient weight loss in the previous 6 months, length of hospital stay, and quality of life 45 , Its sensitivity regarding nutritional risk, however, is poor 40 , It functions more for assessment than screening and requires time and training.

The content validity of the MUST is also ensured as it was developed by a multidisciplinary working group. Predictive validity in the community setting was established based on studies investigating the effect of semi starvation on mental and physical function in healthy volunteers.

This has also been extended to other care settings, where it has shown fair-to-good validity. The MUST has been specifically validated in cancer patients showing low sensitivity and specificity 1 , 4 , 54 , 59 , It demonstrates good predictive validity for clinical outcome length of hospital stay and mortality , for rate of hospital admissions, and for the number of visits to general practitioners The Nutriscore is a recent score and proven to be rapid, simple and effective in the outpatient setting.

It does not perform better than the MUST in the inpatient setting 47 , It shows fair-to-good validity in this setting 31 , which has been confirmed by various studies 31 , 55 , The MST is a poor predictor for clinical outcome.

It is however not predictive for the hospital length of stay in those populations The predictive validity of the NRS was demonstrated by retrospectively analyzing randomized controlled trials on nutritional support, where patients at risk according to the NRS showed a higher likelihood of positive clinical outcome Increasing number of prospective randomized controlled trials investigating the effect of nutritional support in mixed populations including cancer patients using the NRS show improved clinical outcome reduced length of stay, complications, and mortality 64 , NRS demonstrates a fair-to-good validity in mixed hospital populations 20 , The MNA was developed for the elderly population and was originally validated by dietician assessment.

The short form is accepted to be as valid as the full version. The MNA has been studied in all care settings and has a good validity in the elderly in the community, while its validity in hospital settings is poor-to-fair 36 — 39 , There is currently no evidence for the predictive validity of clinical outcome length of hospital stay, complications, and mortality in the elderly population.

The MNA lacks specificity for cancer patients due to the inclusion of some criteria, e. One study performed in lung cancer patients demonstrated a better predictive and prognostic value of MNA compared to weight loss alone in the initial evaluation of the impaired nutritional state Future studies should focus on the validation of nutritional screening tools specifically for oncologic patients - especially as oncologic outpatient numbers are growing.

There is a need to further investigate the challenges and differences between identifying risk in oncology outpatients majority vs. Bozzetti et al. Furthermore, none of the centers had a systematic screening procedure in place and only very few had dieticians available There is an urgent need for action to fill these gaps. The nutritional care process must become an integral part of oncologic outpatient treatment.

Even more recent - oncology tailored- plus other ongoing efforts still do not seem to provide us with the solutions, so needed to tackle these prevalent issues in this still under served critical population. Future efforts should concentrate on the predictive and prognostic value of each criteria of the screening tools, as it can be expected that all of them will have different weights across such diverse presentations, as it is with oncology- i. Establishing predictive and prognostic criteria is of the utmost importance in a field like oncology.

Screening tools are the first step in the nutritional care process. All screening tools presented in this review substantially or moderately agree with each other. Some may help detect nutritional risk, others may predict clinical outcome, others do both in defined populations.

There is currently no general screening tool which can predict clinical outcome in every patient group, in all care settings - especially not for the oncologic population mainly due to the heterogeneity of the disease within patient groups and treatment settings.

Additionally, the cancer care journey of each patient is unique — the disease itself is very different within each individual patient. The quick and easy screening tools mostly lack sensitivity. High sensitivity may be preferred to higher specificity for screening tools. Patients identified as being at high nutritional risk should undergo further assessment by a dietician and receive an individualized care plan.

Health care professionals must be aware of these limitations and implications while screening patients, and must carefully select the appropriate nutritional screening tool depending on the target population, care setting, etc. The validation of screening tools in the oncologic population is inadequate, however, screening is still the most important goal.

Consistent integration across the board of the oncology care pathways should be achieved. As malnutrition remains a distressingly undertreated issue, early screening and consecutive rapid initiation with adequate nutritional support should be an integral part of the multimodal oncologic regime — always with the intention of maintaining and improving patients' clinical outcome and quality of life.

Recommended Tools for Nutritional Screening Several screening tools are available; each with its own individual characteristics. Table 1 Criteria used for the nutritional screening in different tools, modified according to 2 , Open in a separate window.

Mini Nutrition Assessment MNA The MNA was developed to assess the nutritional status in older people who may be frail, living in long-care facilities, or hospitalized Nutriscore The Nutriscore was recently developed for oncology outpatients as an expert consensus from different dietetic and nutrition units from the Catalan Institute of Oncology on the basis of the MST Validation of Screening Tools in the Oncology Population Validation of screening tools is important as it shows whether the tool is able to detect what it is intended to or not.

The PDQ summaries are based on an independent review of the medical literature. This PDQ cancer information summary has current information about nutrition before, during, and after cancer treatment.

It is meant to inform and help patients, families, and caregivers. It does not give formal guidelines or recommendations for making decisions about health care. Editorial Boards write the PDQ cancer information summaries and keep them up to date. These Boards are made up of experts in cancer treatment and other specialties related to cancer.

The summaries are reviewed regularly and changes are made when there is new information. The date on each summary "Updated" is the date of the most recent change. The information in this patient summary was taken from the health professional version, which is reviewed regularly and updated as needed, by the PDQ Supportive and Palliative Care Editorial Board. A clinical trial is a study to answer a scientific question, such as whether one treatment is better than another.

Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients. During treatment clinical trials, information is collected about the effects of a new treatment and how well it works. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard. Some clinical trials are open only to patients who have not started treatment.
