nosed hematologic malignancies and its association to

functional activity.

Methods:

The study included 108 patients aged

65 during

the period 2013-2015 year with newly diagnosed hematologic

malignancies.Patientswere classified aswithoutmalnutrition,

malnourished or at risk for malnutrition according to MNA

score (0-7, 8-11, 12-14, respectively). Functional activity was

assessed using scores for activities of daily living (ADL), and

instrumental activities of daily living (IADL).

Results:

There were 50 (46%) patients diagnosed with

chronic lymphoproliferative disease, 14 (12%) with chronic

myeloproliferative disease, 16 (14.8%) with multiple myeloma,

16 (14.8%) with myelodysplastic syndrome and 8 (7.4%) with

acute leucaemia. Normal nutritional status was present in 61

(56.5%), at the risk of malnutrition were 33 (30.6%) patients

and malnourished were 14 (13%) patients. MNE correlated to

ECOG (ro 4.44, p<0.001),ADL (ro 4.38, p<0,001) and IADL (ro 6.05,

p<0.001). IADL shown predictive for malnutrition (p=0.003).

Conclusion:

Nutritional status is poorer in patients with

worse general condition. Functional dependence estimated

with IADL is predictive for nutrition status using short-form

MNA in older patients with newly diagnosed hematologic

malignancy.

Introduction:

Traditional performance status (PS) assess-

ments such as those delineated by the Eastern Cooperative

Oncology Group (ECOG) are commonly used in oncology

practices to decide on candidacy for treatment as well

as to monitor tolerance to therapy. Previous research has

demonstrated that ECOG PS can be augmented by additional

assessment of performance in older individuals. Mobile

health technology is rapidly evolving and the use of wearable

sensors is an innovative approach to assessing functional and

physical performance.

Objectives:

This initial cohort study aims to compare

traditional ECOG PS assessments by oncology physicians

to patient activity data collected remotely using a wearable

mobile health device.

Methods:

Patients seen in our comprehensive oncology

center are offered to participate in a one week study to collect

remote activity data. Target enrollment is 100 individuals,

who are age 60 or older with an oncologic diagnosis.

Physician-assessed ECOG PS was extracted from pre-

treatment consultation. Patients were asked to wear a mobile

health device for a continuous 7-day period. Commercial

smartwatches were used with a specially designed

application using data analytics modeled specifically for

older individuals. The smartwatches monitored cumulative

steps taken in addition to positional data. Step count data

was used to stratify patient activity into minimally active

(less than 10000 steps), very active (greater than 35000 steps),

and intermediate groups. Positional data was grouped into

sitting/laying or standing/walking as a percentage of time

that the individual wore the smartwatch. Patients were also

asked to complete a post-watch survey to determine level of

adherence, barriers to use, and overall impression of remote

health monitoring.

Results:

Preliminary interim analysis was performed on 31

patients with an oncologic diagnosis who provided informed

consent for this study. Mean age of participants was 71.9

(range 60-91). Mean steps taken by subjects over the 7-day

study period was 35804 (range 2401-111040). Total step count

was found to be closely representative of physician-assessed

ECOG PS by chi-square analysis (p = 0.016). Positional data

showed a trend towards significance when correlated to

physician-assessed ECOG PS by chi-square analysis (p = 0.068).

Post-watch survey responses revealed that most participants

felt the smartwatch was easy to use. 83% of respondents

indicated they would be willing to wear a mobile health

monitoring device again. The most commonly cited barrier to

adherence was limitations on device battery life.

Conclusion:

Activity data from wearable sensors correlated

with ECOG PS, but also showed variance amongst each ECOG

PS level. This suggests the potential that remote activity

monitoring can be used to better augment and enhance

geriatric assessment screening models. The limitation of this

approach is the variability between individuals and the extent

each individual wears their smartwatch. Patient perspectives

reflected the ease of using a smartwatch and overall positive

experience. Future studies will aim to further correlate mobile

health datawith alternate pre-treatment baseline assessments,

interactive smartwatch questionnaires, and patient outcomes.

Introduction:

Aging is a major risk factor for cancer. Living

longer is a valuable achievement, but the magnitude of this

achievement depends largely on how we live this period.

Health-related Quality of life is an important aspect to be

studied in the elderly population with cancer, not as only the
