Kuantitas dan kualitas asupan protein belum sepenuhnya diketahui perannya terhadap kualitas hidup. Prognostic Nutritional Index (PNI) juga belum diketahui dapat mencerminkan kualitas hidup dan apakah bisa ditingkatkan dengan asupan protein. Penelitian dengan desain potong lintang ini bertujuan untuk mengetahui korelasi antara asupan protein dengan PNI dan kualitas hidup serta korelasi PNI dengan kualitas hidup pada pasien kanker kepala leher dengan radioterapi di Departemen Radioterapi Rumah Sakit dr. Cipto Mangunkusumo, Jakarta. Sebanyak 61 subjek didapatkan dari consecutive sampling. Rerata usia subjek adalah 46,3 ± 12,4 dan 65,6% subjek berada pada kanker stadium IV dan mendapatkan terapi kemoradiasi. Sebanyak 32,8% subjek yang memiliki status gizi kurang. Median asupan protein adalah 1,42 (0,26-4,11) g/kg/hari. Nilai PNI pada subjek penelitian memiliki median 45,9 (29,4-54,2). Hasil penelitian menunjukkan adanya korelasi bermakna antara kuantitas asupan protein berdasarkan Food Frequency Questionnaire (FFQ) semikuantitatif dan beberapa aspek gejala pada kualitas hidup yaitu pada aspek pain (head and neck) (r=-0,32; p=0,01), swallowing (r=-0,37;p=0,004), social eating (r=-0,29; p=0,02), dry mouth (r=-0,41; p=0,001), sticky saliva (r=-0,32; p=0,01), fatigue (r=-0,28; p=0,03), nausea and vomiting (r=-0,26; p=0,04) dan appetite loss (r=-0,3; p=0,01). Kualitas asupan protein tidak berkorelasi bermakna dengan kualitas hidup. PNI berkorelasi bermakna terhadap 1 aspek fungsional yaitu physical function (r=0,378; p=0,003) dan 2 aspek gejala yaitu opening mouth (r=-0,325; p=0,01) dan dyspnea (r=-0,257; p=0,045). Meskipun tidak signifikan secara statistik, namun PNI memiliki arah korelasi yang positif terhadap aspek fungsional lainnya dan memiliki arah korelasi negatif terhadap aspek gejala lainnya yang berarti semakin tinggi PNI maka aspek fungsional semakin baik dan gejala semakin ringan. Studi ini tidak menemukan adanya korelasi bermakna antara asupan protein, baik kualitas maupun kuantitasnya, terhadap PNI. Hasil ini diduga berkaitan dengan penemuan bahwa sebagian besar penderita masih memiliki pola asupan yang mampu mencukupi kebutuhan kalori dan protein harian. Diperlukan studi prospektif yang menelusuri aspek prognostik kanker kepala leher dari segi kualitas hidup untuk mengetahui apakah PNI dapat memprediksi aspek kualitas hidup dengan lebih rinci. ......Quality and quantity of protein intake has not been well understood that it can affect quality of life. Moreover, Prognostic Nutritional Index (PNI) also has not been well studied upon its usage to reflect quality of life of head and neck cancer patients undergoing radiotherapy. This cross sectional study was aimed to determine the correlation between protein intake and PNI and also the correlation between PNI and quality of life in head and neck cancer patients undergoing radiotherapy at Radiotherapy Department, dr. Cipto Mangunkusumo General Hospital, Jakarta. Total of 61 subjects were recruited with consecutive sampling method with mean age of 46,3 ± 12,4 years old and 65,6% subjects were on stage IV cancer and were getting a combination of chemo and radiotherapy. Only 32,8% subjects were on low nutritional status. Median of total protein intake was 1,42 (0,26-4,11) g/kg/day. Median of PNI was 45,9 (29,4-54,2) among subjects. The result of the study showed a significant correlations between quanitity of protein intake based on semiquantitative Food Frequency Questionnaire (FFQ) with several aspects of quality of life, that were pain (head and neck) (r=-0,32; p=0,01), swallowing (r=-0,37; p=0,004), social eating (r=-0,29; p=0,02), dry mouth (r=-0,41; p=0,001), sticky saliva (r=-0,32; p=0,01), fatigue (r=-0,28; p=0,03), nausea and vomiting (r=-0,26; p=0,04) dan appetite loss (r=-0,3; p=0,01). This aspects were all symptomatics. PNI was significantly correlated with 1 functional aspect, which was Physical function (r=0.378; p=0,003) and 2 symptomp aspects, which were opening mouth (r=-0,325; p=0,01) dan dyspnea (r=-0,257; p=0,045). Although not statistically significant, but there were positive direction of correlation with other functional aspects and negative direction of correlation with other symptomps aspects. This implicates that the higher the PNI, the lower the symptoms and the better the functional status of head and neck cancer patients undergoing radiotherapy. This study did not show a significant correlation between quality and quantity of protein intake with PNI. An adequate intake of calorie and protein in most subjects were found in this study which might explain the result. More studies, preferably prospective one, may be needed to show the usage of PNI to reflect quality of life, especially involving quality of life progresivity.

Hasil penelitian menunjukkan bahwa sebagian besar subyek 71,2 memiliki kadar CRP serum normal, mengalami penurunan berat badan ge;5 dalam waktu sebulan 76,9 dengan rerata penurunan berat badan -9,42 7,76 , dan juga mengalami mukositis oral 65,4 dengan persentase terbanyak yaitu derajat 1 59,6 . Tidak terdapat mukositis oral derajat 3 dan 4. Tidak terdapat korelasi antara kadar CRP serum dengan penurunan berat r=0,166; p=0,239 , dan mukositis oral r=0,137; p=0,331 . Kesimpulan adalah kadar CRP serum saat radioterapi tidak memengaruhi penurunan berat badan dan mukositis oral. Sebagian besar subyek tetap mengalami penurunan berat badan selama menjalani radioterapi sehingga pemasangan NGT yang lebih awal yaitu sebelum terapi radiasi dimulai NGT profilaksis perlu dilakukan, namun hal ini membutuhkan penelitian lebih lanjut. ......Serum CRP levels can be used as a predictor of weight loss and prognostic indicator of inflammation. This study was conducted to determine the correlation of serum CRP levels with weight loss and oral mucositis in patients with head and neck cancer undergoing radiotherapy. This study was an observational study in the head and neck cancer patients who have undergone radiation therapy at least 25 times at the Department of Radiotherapy RSUPNCM Jakarta with aged ge 18 ndash 65 years old. Our study results showed that most of the subjects 71,2 had normal serum CRP levels, weight loss of ge 5 in one month 76,9 , and also experienced oral mucositis 65,4 . Mostly had grade 1 oral mucositis 59,6 . There were no grade 3 and 4 oral mucositis.There were no correlation between serum CRP levels with weight loss r 0,166 p 0,239 , and oral mucositis r 0,137 p 0.331 . In conclusion, serum CRP levels did not influence weight loss and oral mucositis in patients with head and neck cancer undergoing radiotherapy. Most of the subjects still experienced weight loss during radiotherapy. Therefore, NGT prophylaxis is needed, but this requires further study.

Latar Belakang: Pengobatan Kanker kepala leher (KKL) melalui terapi radiasi maupun kemoradiasi sering menimbulkan efek samping. Efek samping terapi radiasi pasien KKL menyebabkan gangguan asupan yang meningkatkan kejadian malnutrisi. Ketersediaan jalur nutrisi enteral merupakan salah satu tata laksana nutrisi yang dapat diberikan untuk mencegah penurunan asupan dan status gizi pasien KKL. Penelitian ini bertujuan melihat korelasi antara ketersediaan jalur nutrisi enteral dengan pemenuhan nutrisi dan status gizi. Metode: Studi potong lintang dilakukan pada subjek dewasa dengan KKL pasca terapi radiasi di poliklinik radioterapi RSCM. Pemenuhan nutrisi dinilai dengan FFQ semi kuantitatif sedangkan status gizi diukur dengan menghitung indeks massa tubuh (IMT). Ketersediaan jalur nutrisi enteral didapatkan melalui wawancara dan rekam medis pasien. Hasil: Sebanyak 41 subjek penelitian dengan rerata usia 51 tahun ikut serta dalam penelitian. Sebagian besar subjek adalah laki-laki, diagnosis kanker nasofaring, stadium IV, dan jalur nutrisi oral. Rerata IMT subjek 20,5 ± 3,6 kg/m2 dan rerata asupan subjek 1336,7 ± 405,5 kkal/hari. Rerata IMT subjek dengan jalur nutrisi enteral lebih rendah dibandingkan dengan jalur nutrisi oral yaitu 18,2 ± 2,6 kg/m2 dibanding 21,2 ± 3,5 kg/m2. Rerata total asupan energi subjek dengan jalur nutrisi enteral lebih tinggi dibandingkan dengan jalur nutrisi oral yaitu 1498,1 ± 430,6 kkal/hari dibanding 1291,4 ± 393,3 kkal/hari. Terdapat korelasi nagatif sedang antara ketersediaan jalur nutrisi enteral dengan status gizi (r=-0,346, p=0,027) dan korelasi positif lemah dengan pemenuhan nutrisi (r=0,216, p=0,174). Meskipun demikian pada penelitian ini ditemukan bahwa proporsi subjek yang mendapat jalur nutrisi enteral dan mengalami penurunan IMT lebih sedikit dibandingkan dengan proporsi subjek yang menggunakan jalur oral, yaitu 22,2% dengan 43,8%. Kesimpulan: Terdapat korelasi negatif sedang yang signifikan antara ketersediaan jalur nutrisi enteral dengan status gizi dan korelasi positif lemah dengan pemenuhan nutrisi yang masih dipengaruhi oleh faktor perancu penelitian. ......Background: Treatment of head and neck cancer (HNC) through radiation therapy or chemoradiation often lead to side effects. The side effect of radiation therapy in HNC patients might deteriorate food intake that increase the incidence of malnutrition. The availability of enteral nutrition is one of nutritional interventions that can be provided to prevent detrimental of food intake and nutritional status in HNC patients. This study aims to evaluate the correlation between the availability of enteral nutrition with nutritional fulfillment and nutritional status. Method: A cross sectional study was conducted on adult HNC patients after radiation therapy at Radiotherapy Outpatient Clinic of Dr. Cipto Mangunkusumo Hospital. Nutritional fulfillment was assessed by semi-quantitative food frequency questionnaire (FFQ) while nutritional status was measured by calculating body mass index (BMI). The availability of enteral route was obtained through interviews and patients medical records. Results: A total of 41 subjects with a mean age of 51 years participated in the study. Most of the subjects were male, with stage IV nasopharyngeal cancer and oral nutrition route. The mean of BMI was 20,5 ± 3,6 kg/m2 and the mean food intake was 1336,7 ± 405,5 kcal/day. The mean BMI of subjects with enteral nutrition was lower than those on oral nutrition, which was 18,2 ± 2,6 kg/m2 compared to 21,2 ± 3,5 kg/m2. The mean total energy intake of subjects with enteral nutrition route was higher than oral nutrition route, which was 1498,1 ± 430,6 kcal/day compared to 1291,4 ± 393,3 kcal/day. There was a moderate negative correlation between the availability of enteral nutrition and nutritional status (r=-0,346, p=0,027), meanwhile there was a weak positive correlation with nutritional fulfillment (r=0,216, p=0,174). However, in this study we found that the proportion of subjects with enteral nutrition who experienced a decrease of BMI was less than the proportion of subjects on the oral route, which was 22,2% compared to 43,8%, respectively. Conclusion: There is a moderate negative correlation between the availability of enteral nutrition which was statistically significant with nutritional status and a weak correlation with nutritional fulfillment which was still influenced by confounding factors.

Abstrak :
Latar belakang: Pasien kanker kepala leher (KKL) yang mendapatkan kemoradiasi berisiko mengalami malnutrisi dan meningkat hingga 88 % saat akhir kemoradiasi. Efek samping kemoradiasi berupa xerostomia, mukositis, mual atau muntah menambah penurunan status nutrisi dan kapasitas fungsional. Monitoring status nutrisi melalui penilaian berat badan (BB) dan kekuatan genggam tangan (KGT) sebagai cara sederhana dan minimal invasif dibandingkan alat pemeriksaan lain seperti pengukur komposisi tubuh dan Dual Energy X-Ray Absorptiometry (DEXA). Belum diketahui frekuensi kunjungan optimal ke poli gizi selama menjalani kemoradiasi. Metode: Penelitian ini menggunakan metode potong lintang, dilakukan di Radioterapi RSCM (IPTOR RSUPNCM).Penelitian ini bertujuan melihat korelasi frekuensi kunjungan pasien KKL yang menjalani kemoradiasi terhadap BB dan KGT, dengan kriteria inklusi adalah pasien KKL dewasa, usia 19 hingga 59 tahun, yang menjalani kemoradiasi pada 10 fraksi terakhir, dan bersedia masuk dalam penelitian.

Abstrak :
Pasien kanker kepala-leher berisiko tinggi mengalami malnutrisi disebabkan oleh perubahan metabolisme, lokasi tumor, serta gejala toksisitas akut akibat kemoradiasi. Terapi medik gizi secara dini sejak pasien terdiagnosis kanker untuk mencapai asupan energi dan protein yang adekuat, didukung asupan branched-chain amino acid (BCAA) dan eicosapentaenoic acid (EPA) sesuai target, serta aktivitas fisik dapat menjaga massa otot dan status gizi pasien. Acute kidney injury (AKI) merupakan efek toksisitas obat kemoterapi berbasis platinum yang sering dialami pasien. Kondisi tersebut dapat menghambat optimalisasi pemberian nutrisi khususnya protein pada pasien kanker. Tiga dari empat pasien serial kasus sudah mengalami penurunan berat badan drastis, juga pre-kaheksia atau kaheksia sebelum mendapat terapi medik gizi. Selama menjalani kemoradiasi, asupan keempat pasien mengalami penurunan akibat gejala toksisitas akut yang semakin memberat mulai minggu ke-2 radiasi, sehingga tiga dari empat pasien tidak dapat mencapai target asupan energi dan protein pada sebagian besar pemantauan, dengan kisaran antara 6–41 kkal/kgBB/hari dan 0,3–1,6 g/kgBB/hari. Pemberian oral nutrition supplements (ONS) dan nutrisi enteral melalui nasogastric tube (NGT) membantu pemenuhan makronutrien, mikronutrien, serta nutrien spesifik. Berbagai studi menyatakan bahwa pasien yang mendapat terapi medik gizi disertai konseling nutrisi rutin mengalami penurunan berat badan lebih sedikit selama menjalani kemoradiasi. Keempat pasien serial kasus ini mengalami penurunan berat badan >10% selama menjalani kemoradiasi, terutama dari penurunan massa otot. Pasien juga mengalami penurunan kapasitas fungsional dan kualitas hidup. Dua orang pasien yang mendapat terapi medik gizi sejak sebelum kemoradiasi disertai asupan nutrien spesifik sesuai target, dengan rentang asupan BCAA 3,5–16,2 g/hari dan EPA 1–1,38 g/hari, mengalami penurunan berat badan dan kualitas hidup relatif lebih sedikit dibanding dua pasien lainnya. Dibutuhkan asupan energi ≥30 kkal/hari dan asupan protein ≥1,2 g/hari disertai peningkatan aktivitas fisik untuk mempertahankan atau meningkatkan massa otot. Penurunan asupan masih dapat terjadi hingga beberapa minggu pascakemoradiasi, sehingga pemberian terapi medik gizi juga harus dilanjutkan setelah terapi kanker selesai. ......Patients with head and neck cancer are at risk of malnutrition as a result of the metabolic alteration, site of their cancer, also acute toxicity following chemoradiation therapy. Early nutrition intervention consisted of adequate energy, protein, BCAA, and EPA intake, including physical activity initiated immediately after diagnosis was made, may maintain skeletal muscle mass and nutritional status. Platinum-based chemotherapy drug-induced nephrotoxicity can hinder the optimization of protein intake in cancer patients. Three out of four patients in this case series had experienced severe weight loss, also pre-cachexia and cachexia before initiation of nutrition intervention. Energy and protein intake of three patients remained insufficient until the end of chemoradiation therapy, ranged from 6–41 kcal/kg/day and 0,3–1,6 g/kg/day. These inadequacies were mainly caused by acute radiation toxicities that worsen as radiation went on. Oral nutrition supplements and enteral tube feeding may help to achieve adequate macronutrient, micronutrient, and specific nutrient intake. A number of studies demonstrated that regular dietary counseling during chemoradiation was associated with less weight loss. All patients in this case series suffered from weight loss >10%, mainly from skeletal muscle loss. Functional status and quality of life during chemoradiation therapy were also reduced. Better quality of life and less weight loss were seen in two patients who received early nutrition intervention and reached the daily intake target of specific nutrient, ranged from 3,5–16,2 g/day for BCAA and 1–1,38 g/day for EPA. Energy intake ≥30 kcal/day and protein intake ≥1,2 g/day combined with increased physical activity are needed to maintain or increase muscle mass. Side effects of radiation can last for months after treatment; therefore, nutrition intervention should be continued to maintain good nutrition after radiation therapy.
