Sarcopenia , as defined by reduced muscle mass alone , was found to be very prevalent in patients with lung cancer , regardless of body mass index , and where present was associated with poorer functional status and overall survival .
The effect of nutritional supplements and ATP infusions on muscle mass showed conflicting results .
There are very limited data on the correlation between degree of sarcopenia and muscle function , which has a non-linear relationship in older non-cancer population s. CONCLUSIONS Loss of muscle mass is a significant contributor to morbidity in patients with lung cancer .
OBJECTIVES There is growing awareness of the relationship between sarcopenia ( loss of muscle mass and function ) , and outcomes in cancer , making it a potential target for future therapies .
In order to inform future research and practice , we undertook a systematic review of factors associated with loss of muscle mass , and the relationship between muscle function and muscle mass in lung cancer , a common condition associated with poor outcomes .
Objective evaluation of physical function in patients with advanced lung cancer: a preliminary report.
PURPOSE This prospect i ve study was design ed in order to compare the most common subjective measurements of physical function in patients with advanced lung cancer with an objective physical functional test ( Simmonds Functional Assessment Tool [ SFA ] ) . PATIENTS AND METHODS One hundred patients agreed to participate and complete the study before or after their outpatient medical oncology appointment . Patients underwent assessment using the  Karnofsky , the Brief fatigue Inventory , The Functional Assessment of Cancer Therapy-Lung patients ( FACT-L ) and the  Edmonton Symptom Assessment Scale ( ESAS ) . These results were compared to the SFA tool . The SFA consists of six tasks : tying a belt , putting coins in a cup , reaching above head , st and ing up/sitting down , reaching forward and walking 50 feet . RESULTS Ninety-nine patients completed the study over 8 months : median Karnofsky performance status was 85 ( 70 to 100 ) , Edmonton Symptom Assessment Scale ( ESAS ) score ( 0 to 10 ) was generally low ( 0.5 to 2.8 ) . SFA scores were significantly different in patients compared to a control group . The correlation between the subscales of the SFA and the Karnofsky , the Brief Fatigue Inventory , The FACT-L and the ESAS was generally low to moderate ( r values : 0.22 to 0.38 ) . There was generally a moderate correlation between the different subjective scales ( r values : 0.3 to 0.62 ) . CONCLUSION Adherence to the SFA tool was excellent . The low to moderate correlation between the abnormalities found in the objective SFA and the subjective fatigue tests suggest that objective evaluation of the functional capacity provides a potentially useful and independent end-point for clinical trials and therapeutic interventions . These assessment tools should be used complementary to each other to better assess the functional status of patients with advanced lung cancer . Large trials of objective functional assessment are justified
