Abstract

Radioterapi berperan penting dalam pengobatan keganasan leher rahim, baik untuk stadium dini maupun lokal lanjut.Secara anatomi beberapa organ tubuh akan berada dalam lapangan radiasi daerah pelvis. Organ-organ tersebut adalah buli-buli,usus halus, kolon, ovarium dan uterus.Usus halus adalah salah satu organ yang harus sekecil mungkin masuk lapangan radiasi. Pemberian total dosis radiasi 46 - 50 Gy dapat meningkatkan kejadian efek samping pada usus halus yang berupa malabsorbsi dengan gejala yang timbul berupa diare, kram perut, meteorismus sampai obstruksi.Teknik radiasi eksterna daerah pelvis dengan menggunakan bantal baji yang diletakkan dibawah perut pasien (posisi pasien prone diatas meja tindakan) dapat mengurangi luas usus halus yang berada aalam lapangan radiasi dibandingkan dengan teknik radiasi eksterna pelvis yang konvensional (posisi pasien supine diatas meja tindakan).Dari penelitian terhadap 10 pasien kanker leher rahim di Instalasi Radioterapi RS.Kanker Dharmais Jakarta antara bulan Oktober 2007 sampai dengan Pebruari 2008 didapatkan perbedaan rata-rata luas usus halus yang berada dalam lapangan radiasi antara kedua teknik diatas cukup signifikan, yaitu 13,75 %. Rata-rata luas usus halus yang berada dalam lapangan radiasi pada teknik konvensional adalah 24,43 %, sedangkan dengan teknik menggunakan bantal baji 10,68 %.Bantal baji yang dipakai terbuat dari busa polyurethane dengan dua tipe, tipe A dengan kemiringan bantal 30°, dipakai untuk pasien dengan separasi < 15 cm dan tipe B dengan kemiringan bantal 45° yang dipakai untuk pasien dengan separasi s 15 cm.Kata kunci: posisi prone, radioterapi, kanker leher rahim

Abstract

Lumbosacral lateral projection radiography, particularly of the fifth lumbar vertebra (L5) and Sacrum, often experiences a decrease in contrast due to exposure factors and object thickness. This study aims to analyze the variation in the Virtual Grid ratio of 8:1, 10:1, and 12:1 in lateral projection sacrum examinations using the Pixel Value indicator. This descriptive quantitative study was conducted in May–June 2025 at the Radiography and Physics Laboratory, Department of Radiodiagnostic and Radiotherapy Technology, Jakarta II Polytechnic. The sample consisted of lateral sacrum images with three grid ratio variations. Analysis was performed on the average Pixel Value, followed by statistical testing using SPSS 27 with the One-Way ANOVA method. The results showed the average Pixel Value: 8:1 ratio at 150.94; 10:1 ratio at 150.46; and 12:1 ratio at 152.75 with P>0.05, indicating no significant difference between the grid ratio variations.

Abstract

The set-up aims to find out the value of the shift that occurs while the patient is undergoing the irradiation process on the X-axis (right-left), Y-axis (caudal-cranial), and Z-axis (anterior-posterior). The procedure for collecting research data is by making direct observations and being involved in measuring set-up shifts. The data used amounted to 20 nasopharyngeal cancer patients. Set-up shift measurement data were taken sequentially from fractions 1-33 for each patient using 4 and 9 points locks masks. Analysis of statistical test data using SPSS version 25, to determine the effect of using 4 and 9 points locks masks on shifts in nasopharyngeal cancer irradiation set-up patients with fraction group: Group 1 (fraction 1), Group 2 (Fraction 2 – 15), Group 3 (16-33)  using the Wilcoxon test because the normality test results were not fulfilled. If the p-value ≤ 0.05, there is an effect of using 4 and 9 points locks mask on shifts, while for p-value ≥ 0.05, there is no effect of using 4 and 9 points locks mask on set-up shifts in nasopharyngeal cancer irradiation set-up. The results of the shift in the set-up of 4 and 9 points lock irradiation vertically in the lateral, longitudinal, and vertical directions tend to be positive (left, caudal, posterior). There was no effect of all fraction groups using 4 and 9 points locks on the shift in nasopharyngeal cancer irradiation set-up p-value> 0.05.
