Insidensi Tumor Supratentorial berdasarkan Jenis dan Letaknya di RSUP Dr. Hasan Sadikin Tahun 2012–2013
Abstract
Latar Belakang dan Tujuan: Tumor otak adalah kumpulan sel tidak normal pada otak yang bermultiplikasi dan dapat menyebabkan kerusakan pada jaringan sekitarnya dan organ-organ terkait. Tumor supratentorial adalah tumor otak yang terletak superior terhadap tentorium serebeli. Tentorium serebeli adalah lapisan dural yang memisahkan lobus oksipital pada otak besar dengan otak kecil. Tumor supratentorial adalah 33% dari total tumor otak. Penelitian ini bertujuan untuk menggambarkan angka kejadian tumor supratentorial berdasarkan jenis dan letak tumor.
Subjek dan Metode: Objek penelitian adalah rekam medis pasien dengan diagnosis tumor supratentorial yang masuk ke Rumah Sakit Hasan Sadikin Bandung pada Januari 2012 hingga Desember 2013. Penelitian ini merupakan penelitian deskriptif memakai rancangan studi kasus. Data dibagi kedalam kelompok sesuai dengan jenis dan letak tumor kemudian dilihat karakteristiknya.
Hasil: Terdapat 494 pasien tumor supratentorial tapi hanya ada 168 yang memiliki informasi lengkap. Berdasarkan jenisnya, tumor dikelompokkan secara garis besar menjadi glioma (14,88%), tumor kranial dan paraspinal (0,60%), tumor meningen (70,24%), tumor pada region sella (10,12%) dan tumor metastasis (4,17%). Berdasarkan letaknya, secara garis besar tumor terletak di sisi kanan (35,12%), sisi kiri (36,90%), region sellar (13,69%), sisi tengah (4,16%) dan bilateral (10,12%)
Simpulan: Jenis tumor supratentorial terbanyak adalah meningioma dan lokasi tumor supratentorial paling banyak adalah pada sisi kiri otak secara umum, atau pada lobus frontal secara spesifik.
Incidence of Supratentorial Tumor based on Types and Locations of Tumor in Hasan Sadikin Hospital Year 2012–2013
Background and Objective: Brain tumor is a group of abnormal cells in the brain which multiplies and causes damage to the surrounding tissues and related organs. Supratentorial tumor is a brain tumor which is located at superior of tentorium cerebelli. Tentorium cerebelli is the dural layer which separates the occipital lobe of cerebrum with the cerebellum. Thirty three percent of brain tumor is supratentorial tumor. This study was aimed to observe the prevalence of supratentorial tumor based on the type and location of the tumor.
Subject and Method: The objects of the study were the medical records of patients diagnosed with supratentorial tumor whom admitted to Dr. Hasan Sadikin General Hospital Bandung from January 2012 until December 2013. This study was a case- descriptive study and data was divided into groups based on type and location of the tumor and then analyzed based on the characteristics.
Result: There were 494 patients with supra tentarial tumor, but only 168 patients had complete infomation. Based on the type, tumors were categorized generally into glioma (14.88%), cranial and paraspinal tumor (0.60%), meningeal tumor (70.24%), sellar region tumor (10.12%) and metastatic tumor (4.17%). Based on the location in the brain, tumors were located generally in the right side (35.12%), left side (36.90%), sellar region (13.69%), middle (4.16%) and bilateral (10.12%).
Conclusion: The most common type of supratentorial tumor is meningioma and most common location of supratentorial tumor is in the left side of the brain, particularly in the frontal lobe.
