Malnutrition is common among cancer patients and can lead to decreased quality of life. Therefore, early identification of patients at risk of malnutrition should be performed in all cancer patients, but until now, there is no gold standard of nutrition screening tool that should be used in outpatient radiotherapy setting. This study was a cross-sectional study conducted to compare Malnutrition Screening Tool (MST) and Abridged Patient-Generated Subjective Global Assessment (abPG-SGA) as nutrition screening tools in 144 radiotherapy outpatients against Patient-Generated Subjective Global Assessment (PG-SGA) as the gold standard. Forty-one percent of patients were at risk of malnutrition (PG- SGA). The MST was a simple and quick tool with an average of 21 seconds. It had 84.75% sensitivity, 77.65% specificity, positive predictive value (PPV)=0.73, negative predictive value (NPV)=0.88, and area under the ROC curve (AUC)=0.812. The abPG-SGA yielded 98.31% sensitivity, 92.94% specificity, PPV=0.91, NPV=0.99, AUC=0.956, and it took an average of 2 minutes 24 seconds. In conclusion, the abPG-SGA is a better and more accurate screening tool in outpatient radiotherapy setting."

"Tujuan penelitian ini adalah untuk mengetahui korelasi antara penilaian risiko malnutrisi menggunakan skor PG-SGA dengan kadar CRP serum sehingga dapat digunakan untuk memprediksi tingkat inflamasi pada pasien kanker kepala dan leher stadium I_IV guna mencegah terjadinya kaheksia. Malnutrisi hingga kaheksia pada kanker terjadi karena interaksi faktor tumor, faktor pejamu dan faktor-faktor lainnya. Faktor tumor berupa sitokin pro-inflamasi akan memicu respons pejamu untuk memproduksi protein fase akut seperti CRP. Protein fase akut memerlukan sejumlah substrat yaitu asam amino yang berasal dari otot rangka. Otot rangka akan mengalami degradasi sehingga menyebabkan wasting otot rangka. Oleh karena itu, CRP selain dapat digunakan sebagai marker inflamasi sistemik juga dapat digunakan sebagai salah satu indikator faktor risiko yang berperan dalam terjadinya malnutrisi dan kaheksia. Efek wasting otot rangka yang ditimbulkan secara tidak langsung oleh CRP dapat dinilai dengan terdapatnya penurunan BB maupun berkurangnya massa otot yang juga merupakan komponen dalam penilaian PG-SGA. Penelitian ini merupakan studi potong lintang dengan menggunakan consecutive sampling yang melibatkan 51 subjek kanker kepala dan leher stadium I_IV yang belum mendapatkan terapi. Hasil penelitian didapatkan rerata usia 46,6 13,9 tahun, sebanyak 76,5 berjenis kelamin laki-laki. Kanker nasofaring merupakan kanker terbanyak 80,4 , dan stadium terbanyak yaitu stadium IVA. Rerata indeks massa tubuh IMT yaitu 20,6 4,0 kg/m2, dan sebanyak 37,3 subjek berada pada IMT normal. Berdasarkan skor PG-SGA sebanyak 64,7 subjek berisiko tinggi malnutrisi dengan rerata skor PG-SGA 11,7 6,2. Nilai median CRP yaitu 6,4 0,4_170,4 . Penelitian ini memperoleh korelasi positif yang signifikan antara skor PG-SGA dengan kadar CRP serum dengan kekuatan korelasi lemah r = 0,372; p = 0,007.

The purpose of this study was to determine the correlation between the malnutrition risk assessment using PG SGA score with serum CRP levels so that it can be used to predict the levels of inflammation in head and neck cancer patients stage I IV to prevent cachexia. Malnutrition and cancer cachexia occurs due to the interaction of tumor factors, host factors and other factors. Tumor factors such as pro inflammatory cytokines will trigger a response of the host to produce acute phase proteins such as CRP. Acute phase protein which require a number of amino acids derived from skeletal muscle. Skeletal muscles will be degraded, causing skeletal muscle wasting. Therefore, CRP can be used as a marker of systemic inflammation and can be used as one indicator of the risk factors also that contribute to malnutrition and cachexia. Effect of skeletal muscle wasting which caused indirectly by the CRP can be assessed by the weight loss and reduced muscle mass which is a component in the assessment of PG SGA also. This study is a cross sectional study using consecutive sampling, 51 subjects head and neck cancer stage I IV who had not received treatment participated in this study. Data showed the mean age of subjects was 46.6 13,9 years, and 76 were male. Most cancer sites were as nasopharyngeal 80,4, and mostly in stage IVA. The mean body mass index BMI is 20,6 40 kg m2, with most of the BMI is normal 37,3. Based on PG SGA score 64,7 of the subjects at high risk of malnutrition, and the PG SGA mean score is 11,7 6,2. The median value of CRP is 6,4 0,4 170,4. The result of this study showed a significant positive correlation between PG SGA score with serum CRP levels with the strength of correlation is weak r 0,372 p 0,007. "
