“…Teknik 3D-CRT merupakan salah satu metode iradiasi yang digunakan dalam pengobatan radioterapi eksternal. Untuk dapat menyesesuaikan dengan bentuk tumor, teknik 3D-CRT mengaplikasikan lapangan radiasi yang konformal sesuai target dan intensitas radiasi yang homogen, berbeda dengan IMRT yang intensitas keluarannya di modulasi pada setiap arah penyinaran (Febrietri et al, 2020).…”

Abstrak: Analisis Dosis Radiasi Paru Pada Pasien Radioterapi Kanker Payudara Dengan Teknik 3D-CRT Berdasarkan Grafik DVH. Kanker payudara merupakan penyebab utama kematian akibat kanker setelah kanker paru. Radiasi dapat menyebabkan kerusakan sel di paru-paru yang berujung pada pneumonitis dan penurunan fungsi paru sehingga pengendalian dosis paru pasien kanker payudara penting dilakukan. Dalam hal itu dosis radiasi PTV dikontrol dalam ketentuan ICRU report 62, dan batas toleransi dosis yang dapat diterima paru dikontrol dalam ketentuan QUANTEC V20 <30% dan Dmean <2700 cGy. Penelitian ini merupakan penelitian analisis kuantitatif dengan pendekatan deskriptif observasional yaitu menganalisis data secara sistematik dan melihat kesesuaian dosis radiasinya berdasarkan ketentuan ICRU report 62 dan QUANTEC. Dari 10 sampel yang diteliti, 70% menerima dosis radiasi PTV sebesar 95%-107%, dan 30% menerima dosis radiasi PTV diatas 107%. Sebanyak 10% sampel, kurang dari 30% volume parunya menerima dosis 2000 cGy. Sisanya 90%, lebih dari 30% volume parunya mendapatkan dosis 2000 cGy. Dan mean dose keseluruhan pasien kurang dari 2700 cGy. 70% sampel mendapat dosis optimal dan memenuhi ketentuan ICRU Report 62, sisanya 30% melebihi batas ketentuan. 10% sampel memenuhi ketentuan QUANTEC V20<30%. Sedangkan sisanya 90% tidak memenuhi V20<30% dan 100% sampel mendapat dosis Dmean kurang dari 2700 cGy.

ABSTRACTLung cancer is a malignant tumor that develops in the lower respiratory system, including cells in the walls of the bronchi and bronchioles. Lung cancer originates from genetic changes in cells in the lungs. Improper treatment of lung cancer can cause the cancer to spread to other nearby tissues around the lungs. By conducting early detection of lung cancer, it will help patients to get appropriate treatment. One of the medical instruments used to detect lung cancer is the CT-Scan. This instrument’s examination can provide information about the location, size, characteristics of the tumor, lymph node spread, and tissue infiltration into the surroundings, thus helping to determine the clinical stage of lung cancer. Organ size determination is one of the analysis of pulmonary image for diagnostic and therapeutic purposes. The purpose of this study was to obtain information on the volume of lung cancer based on the results of CT Scan images using Image J software. Information on the edges of the lungs affected by cancer was carried out by the edge detection method. The results of this study show that Image-J software can provide a clear picture of the edges of the cancer and obtain accurate cancer volume at each image slice. Based on calculations obtained in the 1st patient, it was calculated to have a volume of 128 cm3, in the 2nd patient of 447 cm3 and in the 3rd patient of 335 cm3, respectively.Keywords: Ct Scan image; lung cancer; edge detection; volume analysis; Image JABSTRAKKanker paru merupakan tumor ganas yang berkembang pada sistem pernapasan bagian bawah, termasuk sel-sel di dinding bronkus dan bronkiolus. Kanker paru berawal dari perubahan genetik sel di dalam paru-paru. Penanganan kanker paru yang tidak tepat dapat menyebabkan kanker menyebar ke jaringan lain yang terdekat di sekitar paru-paru. Dengan dilakukan pendeteksian dini kanker paru, maka akan sangat membantu penderita agar mendapatkan penanganan yang cepat dan tepat. Salah satu instrumen medis yang digunakan untuk mendeteksi kanker paru adalah pesawat CT-Scan. Pemeriksaan CT-Scan dapat memberikan informasi tentang lokasi, ukuran, karakteristik tumor, penyebaran kelenjar getah bening, dan infiltrasi jaringan ke sekitarnya sehingga membantu penetapan stadium klinis kanker paru. Penentuan ukuran organ merupakan salah satu analisa terhadap citra paru untuk keperluan diagnosa dan terapi. Tujuan penelitian ini adalah memperoleh informasi volume kanker paru berdasarkan hasil citra CT Scan menggunakan Image J. Informasi gambaran tepi paru yang terkena kanker dilakukan dengan metode deteksi tepi. Hasil dari penelitian ini menunjukan bahwa software Image-J dapat memberikan gambaran tepi kanker yang jelas dan diperoleh volume kanker yang akurat pada setiap irisan citra. Berdasarkan perhitungan didapatkan pada pasien ke-1 terhitung memiliki volume sebesar 128 cm3, pada pasien ke-2 sebesar 447 cm3 dan pada pasien ke-3 sebesar 335 cm3.Kata kunci: CT Scan; Kanker paru; deteksi tepi; analisis volume; Image J

“…IMRT is believed to be able to maximize the success of therapy with computerized methods in terms of the formation of a high-accuracy irradiation field according to the shape of the tumor that is read from the results of the CT-simulator examination and the provision of non-uniform radiation intensity according to the needs of each target part in each direction of the irradiation field Febrietri et al (2020). This is able to optimize the radiation dose that will be received by the Planning Target Volume (PTV) and minimize the radiation received by healthy tissue/OAR so that a Dose Volume Histogram (DVH) graph is obtained with satisfactory results.…”

Motivation/Background: Radiotherapy is the standard therapy that uses ionizing rays for the treatment of malignancies. However, in some cases of nasopharyngeal cancer (NPC), the location of the tumor pushes to the base of the brain until it reaches the optic chiasma. The optic chiasm as part of a healthy organ around the target irradiation becomes a dangerous organ or a risk organ (OAR) so it needs to be considered in the case of radiation therapy for NPC. This study aims to consider dosing in patients to fulfill radiation protection. IMRT technique is believed to maximize the success of therapy in cases of NPC.Method: In this study, secondary data was used by looking at the DVH (Dose Volume Histogram) graph from the results of radiation planning for NPC patients using the IMRT (Intensity Modulated Radiotherapy) technique. Data analysis was carried out on PTV and OAR dose values NPC patients at Ken Saras Hospital on the DVH chart that was adjusted to the wishes used, namely The International Commission on Radiation Units and Measurements (ICRU) Report 62 (1999) for PTV doses and QUANTEC for doses OAR.Results: The results of the analysis showed that of the 15 patient data analyzed, there were 10 patients with a percentage of 66.67% who received radiation doses that were in accordance with the ICRU Report 62 reference (95-107%) while patients who received less than optimal doses (< 95%) there were 5 people with a percentage of 33.33% while the maximum dose received by OAR for the optic chiasm in NPC patients who had complied with QUANTEC rules overall there were 7 patients with a percentage of 46.67% while there were 8 patients who received doses exceeding the QUANTEC limit with a percentage of 53 ,33% risk of receiving radiation side effects by 7-20%..Conclusions: there were patients who received doses exceeding QUANTEC as much as 53.33%
