ABSTRAK
Latar Belakang: Malnutrisi berdampak besar pada pasien kanker sehingga harus

dievaluasi dengan Patient-Generated Subjective Global Assessment (PG-SGA),

namun memakan waktu dan membutuhkan tenaga kesehatan terlatih. Pengukuran

kekuatan genggam tangan (KGT) memiliki keuntungan lebih singkat dan mudah

dibandingkan PG-SGA, tetapi belum ada data titik potong dan akurasi diagnostik

KGT pada pasien kanker di Indonesia.

Tujuan: Mendapatkan titik potong dan akurasi diagnostik KGT sebagai penapis

malnutrisi pasien kanker rawat jalan di RSCM.

Metode: Penelitian potong lintang ini dilakukan pada pasien 18-59 tahun di

poliklinik onkologi RSCM selama 4 Mei-1 Oktober 2015. Titik potong KGT

dianalisis menggunakan kurva ROC. Akurasi diagnostik KGT dinilai dengan

menghitung sensitivitas, spesifisitas, NDP, NDN, RKP, dan RKN.

Hasil: Proporsi pasien dengan status nutrisi baik, malnutrisi sedang, dan

malnutrisi berat adalah17,4%, 64,2%, dan 18,4%. Titik potong optimal KGT

pasien kanker lelaki dan perempuan berturut-turut adalah ≤ 36,5 dan ≤ 21,5 kgf

dengan sensitivitas 92,2% dan 73,9%, spesifisitas 54,6% dan 60,9%, NDP 92,2%

dan 88,3%, NDN 54,6% dan 36,8%, RKP 2 dan 1,9, serta RKN 0,1 dan 0,4.

Simpulan: Titik potong optimal KGT pasien kanker lelaki dan perempuan

berturut-turut adalah ≤ 36,5 dan ≤ 21,5 kgf. Akurasi diagnostik KGT pasien

kanker lelaki dan perempuan sebagai penapis malnutrisi berturut-turut dinilai baik dan sedang.ABSTRACT
Background: Malnutrition has a huge impact on cancer patients and therefore it

has to be evaluated using PG-SGA, but there are limitations such as the timeconsuming

nature and the need of trained health personnels. Measurement of

HGS is faster and easier, but there is no sufficient information regarding its cutoff

point

and diagnostic

accuracy

for cancer

patients

in Indonesia.

Aim:

defining cut-off point and diagnostic accuracy of HGS as a malnutrition

screening modality for outpatient cancer population at RSCM.

Method: A cross-sectional study was conducted at RSCM oncology outpatient

clinic from May 4

-October 1

, 2015. Subjects were 18-59 years old. Cut-off

point and diagnostic accuracy of HGS were analyzed to generate sensitivity,

specificity, PPV, NPV, LR+, and LR- .

Result: The proportion of well nourished, moderately malnourished, and severely

malnourished subjects were 17.4%, 64.2%, and 18.4%, respectively. The optimal

HGS cut-off point in male and female cancer patients were ≤ 36.5 and ≤ 21.5 kgf

respectively with sensitivity 92.2% and 73.9%, specificity 54.6% and 60.9%,, PPV

92.2% and 88.3%, NPV 54.6% and 36.8%, LR+ 2 and 1.9, and LR- 0.1 and 0.4.

Conclusion: The optimal HGS cut-off point in male and female cancer patients

were ≤ 36.5 and ≤ 21.5 kgf, respectively. Diagnostic accuracy of HGS as a

malnutrition screening modality in male and female cancer patients were good and moderately good.
