Assessing Nutritional Status in Acute Lymphoblastic Leukemia Patients: A Comparative Study of Middle Arm Muscle Area and Upper Arm Circumference

Introduction

Acute lymphoblastic leukemia (ALL) is a type of cancer that affects the blood and bone marrow, and it is one of the most common forms of malignancy in children. The nutritional status of ALL patients is crucial in determining their overall health and treatment outcomes. In this study, we aim to evaluate the sensitivity of the middle arm muscle area (MAMA) and upper arm circumference (UAC) in assessing the nutritional status of ALL patients undergoing the induction phase of chemotherapy.

Background

Leukemia is a complex and multifaceted disease that requires a comprehensive approach to treatment. Nutritional status plays a critical role in supporting the immune system and promoting healing. However, assessing nutritional status in leukemia patients can be challenging, especially in situations where there are organomegali, mass, or ascites. In such cases, more effective methods of assessment are needed.

The Importance of Nutritional Status in Leukemia Patients

Nutritional status is a critical factor in determining the treatment outcomes of leukemia patients. Good nutrition plays a crucial role in supporting a weak immune system due to disease and treatment. Accurate measurement methods are essential in determining the right nutritional intervention. The middle arm muscle area (MAMA) and upper arm circumference (UAC) are two commonly used methods of assessing nutritional status in leukemia patients.

Research Purpose

This study aims to evaluate the sensitivity of the middle arm muscle area (MAMA) and upper arm circumference (UAC) in determining the nutritional status of ALL patients undergoing the induction phase of chemotherapy. We hypothesize that the upper arm circumference (UAC) will be more sensitive than the middle arm muscle area (MAMA) in detecting malnutrition status.

Research Methods

This study uses a cross-sectional design involving 35 ALL patients who receive induction phase chemotherapy. The sampling technique used is a consecutive sampling, where the area of the middle arm muscles and the upper arm muscles is measured. Analysis of Receiver Operating Characteristic (ROC) is applied to determine the cut-off value, and statistical analysis using the chi-square test is used to compare the sensitivity and specificity of the two methods.

Research Results

Of the 35 patients who met the inclusion and exclusion criteria, as many as 20 patients were identified with malnutritional status based on the measurement of the middle arm muscle area, while 15 patients were based on the measurement of the upper arm circumference. The results of the ROC analysis show that the Under Curve (AUC) area value for the middle arm muscle area is 70% with a cut-off value of 1033.07 mm². Meanwhile, AUC for the upper arm circumference reached 87.8% with a cut-off value of 152.5 mm.

Conclusion

From the results of this study, the sensitivity value for the measurement of the middle arm muscle area is 47%, while for the upper arm circumference it reaches 80%. The specificity for the middle arm muscle area is 70% and 85% for the upper arm circumference. Thus, it can be concluded that the measurement of the middle arm muscle area is no more sensitive than the upper arm circumference in assessing the nutritional status of ALL patients in the induction phase of chemotherapy.

Additional Analysis

The importance of assessing nutritional status in leukemia patients cannot be underestimated. Good nutrition plays a crucial role in supporting a weak immune system due to disease and treatment. Accurate measurement methods are very important to determine the right nutritional intervention. The results of this study indicate that the upper arm circumference is more effective in detecting malnutrition status, providing valuable information for medical personnel in planning better care. Therefore, it is recommended to consider the use of upper arm circumference as a standard method in assessing nutritional status in acute lymphoblastic leukemia patients. Thus, nutritional management can be optimized to support the patient's healing process.

Implications for Practice

The results of this study have significant implications for practice. The use of upper arm circumference as a standard method in assessing nutritional status in ALL patients can help medical personnel to plan better care and optimize nutritional management. This can lead to improved treatment outcomes and reduced morbidity and mortality rates. Furthermore, the use of upper arm circumference can help to identify patients who are at risk of malnutrition, allowing for early intervention and prevention of malnutrition-related complications.

Limitations of the Study

This study has several limitations. The sample size is relatively small, and the study was conducted in a single institution. Therefore, the results may not be generalizable to other populations. Additionally, the study only assessed the sensitivity and specificity of the middle arm muscle area and upper arm circumference in detecting malnutrition status, and did not investigate other aspects of nutritional status, such as protein-energy malnutrition.

Future Directions

Future studies should aim to investigate the sensitivity and specificity of other methods of assessing nutritional status in ALL patients, such as bioelectrical impedance analysis and dual-energy X-ray absorptiometry. Additionally, studies should aim to investigate the relationship between nutritional status and treatment outcomes in ALL patients. This can help to identify the most effective methods of nutritional assessment and intervention, and optimize treatment outcomes.

Conclusion

In conclusion, this study demonstrates that the upper arm circumference is more sensitive than the middle arm muscle area in detecting malnutrition status in ALL patients undergoing the induction phase of chemotherapy. The results of this study have significant implications for practice, and highlight the importance of accurate measurement methods in determining the right nutritional intervention. Therefore, it is recommended to consider the use of upper arm circumference as a standard method in assessing nutritional status in acute lymphoblastic leukemia patients.
