"Latar Belakang : Radiasi berperan sebagai salah satu modalitas penatalaksanaan perdarahan pada keganasan. Peranan radiasi sebagai hemostatiks sudah lama digunakan namun masih memerlukan studi lebih lanjut untuk mengevaluasi efektivitasnya, serta ilmu pengetahuan terbaru pada penggunaan parameter biologis dalam penilaiannya. Saat ini di Indonesia masih sedikit publikasi kepustakaan yang memfokuskan tentang radiasi hemostatiks. Penelitian ini bertujuan untuk mengetahui perubahan respon klinis perdarahan berdasarkan skala perdarahan WHO, mengetahui adanya perbedaan rerata kadar von Willebrand Factor (vWF) plasma antara sebelum dan sesudah radiasi, serta mengevaluasi adanya korelasi dari kadar vWF plasma dengan respon penghentian perdarahan menggunakan skala perdarahan WHO pada perdarahan tumor, sebelum dan sesudah diberikan radiasi hemostatiks.Metodologi : Studi ini menggunakan pre-post study design tanpa pembanding, dilakukan di Departemen Radioterapi RSCM pada pasien yang mengalami perdarahan akibat kanker yang mendapat terapi radiasi hemostatiks serta memenuhi kriteria inklusi sejak September 2013 sampai dengan Februari 2014. Pengambilan sampel darah untuk pemeriksaan vWF plasma dan penilaian klinis skala perdarahan WHO dilakukan sebelum dan sesudah radiasi hemostatiks.Hasil : Dari total 23 subyek terpilih, terdapat 2 pasien yang meninggal karena perdarahan. Nilai keberhasilan terapi radiasi hemostatiks yang dilakukan pada subyek adalah sebesar 91,3%. Radiasi hemostatiks mampu menurunkan skala perdarahan WHO dari median 3 menjadi median 1 sesudah radiasi dengan nilai p<0,001. Pemberian radiasi hemostatiks meningkatkan kadar vWF plasma secara bermakna dengan perbedaan rerata 12,38 IU/dL (SD 12,75 IU/dL), nilai p=0,001. Terdapat korelasi yang bermakna antara peningkatan kadar vWF plasma sebelum dan sesudah radiasi dengan penurunan skala perdarahan WHO, p=0,019 (R=-0,533).Kesimpulan : Radiasi hemostatiks terbukti efektif menghentikan perdarahan akibat kanker dan menjadi modalitas pilihan dalam tatalaksana perdarahan akibat kanker. Radiasi mampu menurunkan derajat perdarahan, serta meningkatkan kadar vWF plasma dan terbukti peningkatan vWF plasma berkorelasi bermakna dengan penurunan derajat perdarahan.

Backgorund : Radiation is one of the modality to treat cancer bleeding. Hemostatics irradiation is already known while still need further investigation to evaluate its effectiveness, including its biological parameter. Von Willebrand Factor plasma is already known has major role as initiator of the platelets adhesion in hemostatics. Publication of references in hemostatics irradiation is still infrequent. This study aims to investigate the changes of clinical response based on WHO bleeding scale before and after radiation, also to examine the difference level of vWF plasma before and after radiation, and to search correlation between bleeding scale response to vWF plasma level before and after hemostatics irradiation.

Methods : This study is pre-post study design without control, held in Department of Radiotherapy Cipto Mangunkusumo National General Hospital, Jakarta in cancer bleeding patients who received hemostatics irradiation according to inclusion criteria, since September 2013-February 2014. Blood samples for vWF examination and clinical scoring for WHO bleeding scale data are taken before and after irradiation.

Result : Overall 23 subjects, including 2 patients died because of the bleeding. The effectiveness of hemostatics irradiation is 91,3%. Radiation hemostatics significantly decrease WHO bleeding scale, from median 3 to median 1, p<0,001. The hemostatics irradiation significantly elevate the level of vWF plasma, mean differences 12,38 IU/dL (SD 12,75 IU/dL), p= 0,001. There is also significant correlation between the decrease of WHO bleeding scale and the elevation level of vWF plasma, p=0,019 (R=-0,533).

Conclussion : Hemostatics radiation is proven effectively to stop the cancer bleeding and chosen modality in treating the cancer bleeding in malignancy. Radiation is clinically able to degrade the bleeding scale, and to elevate the level of vWF plasma. Radiation is also proven significant corelation between elevation of vWF plasma and decrement of bleeding scale."

"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."

Introduction: Acute radiation toxicity was a process which caused by irradiation and initiated by normal cell damage. Malondialdehyde (MDA) is the end product of lipid peroxidation, and is usually used as a biomarker to assess oxidative stress. Catalase (CAT) is an enzymatic antioxidant that catalyzes H2O2 into water and oxygen. The purpose of this study was to determine whether the levels of MDA and CAT activity can be used as a predictor of acute radiation toxicity in locally advanced cervical cancer.

Methods: This is a prospective cohort study to 30 locally advanced cervical cancer patients who meet the inclusion criteria in the Radiotherapy Department of Cipto Mangunkusumo Hospital from July to September 2013. We measure MDA level and CAT activity before irradiation and on 15th fractions using sphectrophotometry. Degree of acute radiation toxicity assessed every week during external beam radiotherapy using RTOG criteria.

Results: The mean of serum MDA levels is 7.6 + / - 1.2 nmol /mL, and the median of CAT activity is 0.95 (0.80 to 1.36) U /mL. We found elevated of serum MDA level to 9.5 +/ - 1.9 nmol /mL (p <0.001) and CAT activity decreased to 0.82 (0.71 to 0.96) U /mL (p <0.001) on the 15th fraction of external beam irradiation. No statistically significant relationship is found between MDA level and CAT activity pre irradiation and its changes to the incidence of acute radiation toxicity.

Conclusion: This study showed that radiation or chemoradiation shown to cause an increase in MDA levels and decrease of CAT activity in locally advanced cervical cancer patients, but MDA levels and CAT activity cannot be a predictor of acute radiation toxicity."

"Pendahuluan: Stres oksidatif selalu terjadi pada pasien kanker dan ditandai dengan kadar Malondialdehyde (MDA) serum yang tinggi dan rendahnya aktivitas antioksidan enzimatik serum katalase (CAT). Penelitian ini menganalisis kadar MDA dan aktifitas enzimatik CAT, yang mewakili status oksidan dan status antioksidan pada pasien dengan kanker serviks uteri stadium lanjut lokal dan bagaimana hubungannya dengan angiogenesis (VEGF), yang bertujuan untuk mengembangkan strategi terapi baru di berbagai kasus keganasan, terutama dalam kasus kanker serviks uteri di masa depan.Metode penelitian: Penelitian ini merupakan studi cross sectional terhadap 16 pasien kanker serviks uteri stadium lanjut lokal (IIB ? IIIB) pada bulan Juli 2013 sampai dengan September 2013 yang memenuhi kriteria inklusi di departemen Radioterapi RSCM. Kadar MDA dan aktifitas enzimatik CAT diperiksa dengan mengambil sampel dari darah sebelum terapi radiasi diberikan. Pemeriksaan angiogenesis diperiksa dengan mengambil sampel biopsi dari jaringan serviks, dan dilakukan pemeriksaan ELISA untuk mendapatkan ekspresi VEGF.Hasil: Pada studi ini didapatkan rerata kadar MDA serum sebesar 7,6 +/- 1,2 nmol/mL, dan median aktivitas CAT sebesar 0,95 (0,80 ? 1,36) U/mL. Ditemukan korelasi positif kuat antara kadar MDA dan ekspresi VEGF dengan koefisien korelasi r = +0.775, dan p < 0.001. Tetapi didapatkan korelasi negatif lemah antara aktivitas enzimatik katalase serum dengan VEGF dengan koefisien korelasi r = -0.310 dan p = 0,909.Kesimpulan: Hasil penelitian ini menunjukkan bahwa stress oksidatif terjadi pada pasien kanker serviks uteri stadium lanjut lokal yang ditandai dengan peningkatan kadar MDA serum yang tinggi dan aktifitas enzimatik katalase yang rendah. Terdapat korelasi positif kuat antara kadar MDA serum dengan VEGF jaringan tetapi didapatkan korelasi negatif yang lemah dan tidak signifikan antara VEGF dengan aktifitas enzim katalase.

Introduction: Oxidative stress always occurs in cancer patient, which characterized with high level of serum Malondialdehyde (MDA) dan low activity of serum catalase enzymatic antioxidant. This study analyzed the levels of malondialdehyde (MDA) and catalase (CAT), which represents the oxidant and antioxidant status in patients with locally advanced uterine cervical cancer and how it relates to angiogenesis to develop new therapeutic strategies in various malignancies, especially in the case of uterine cervical cancer in the future.

Methods: Sixteen of locally advance cervical cancer stage IIB ? IIIB from July 2013 to September 2013 who had irradiated in Radiotherapy department Cipto Mangunkusumo general hospital and eligible for this cross sectional study. MDA levels serum and catalase enzyme serum activities were examined before radiotherapy. Tissue biopsy is taking before radiotherapy, for VEGF analysis is done by ELISA to asses angiogenesis activity.

Results: In this study, mean MDA level is 7.6 + /- 1.2 nmol / mL and catalase enzyme activity median is 0.95 ( 0.8 to 1.36 ) U / mL . paired t-test shows there is a strong significant positive correlation between MDA and VEGF (r = +0.775, p < 0.001). This suggest that increasing MDA serum levels as free radicals activity in line with increasing VEGF as angiogenesis activity, in the other side there is no correlation between VEGF and catalase enzyme serum activities ( r = -0.310 and p = 0.909).

Conclusion: This study showed that oxidative stress occurs in patients with locally advanced cervical cancer, increasing MDA serum levels as free radicals activity in line with increasing VEGF as angiogenesis activity but at the other side there is no correlation between VEGF and catalase enzyme serum activities."
