Pendahuluan: GCT tulang merupakan lesi jinak tetapi secara lokal dapat bersifat agresif pada daerah epifisis. Angka rekurensi yang tinggi, dilaporkan mencapai 75%. Tumor dapat bermetastasis ke paru (2-9%) dan tercatat 0-37% angka mortalitas akibat metastasis. Beberapa penelitian menghasilkan variasi berbeda penanganan tumor ini terhadap luaran onkologi dan fungsional serta angka kematian paska pembedahan. Penelitian ini bertujuan melaporkan pengalaman dalam penatalaksanaan pembedahan tumor ini dan untuk melihat adanya hubungan antara tatalaksana pembedahan dengan dampak klinis. Metode: Penelitian ini merupakan kohort retrospektif, sebanyak 99 pasien GCT tulang menjalani tindakan kuretase ataupun wide resection di Rumah Sakit Cipto Mangunkusumo pada 1995 - 2014. Luaran onkologi berdasarkan angka rekurensi lokal, metastasis tumor serta mortalitas dan luaran fungsional berdasarkan sistem penilaian Musculoskeletal Tumor Society (MSTS). Hasil: Lokasi tumor terutama di distal femur (25,2%). Rekurensi lokal terjadi pada 4 pasien, terutama di distal femur (50%). Rekurensi lokal terjadi seimbang pada wide resection dan kuretase dan secara statistik tidak bermakna (p 0.578, uji eksak Fischer). Tidak dijumpai kejadian rekurensi lokal pada seluruh pasien yang mengalami metastasis. Metastasis terjadi pada kelompok wide resection. Kematian terjadi pada 4 pasien yang mengalami metastasis. Sebagian besar pasien (51,1%) menunjukkan luaran fungsional kategori sangat baik (skor MSTS di atas 75%). Analisis kesintasan bebas rekurensi lokal secara statistik tidak bermakna (p 0.564). Analisis multivariat (regresi Cox) hanya faktor metastasis yang berpengaruh pada mortalitas (p. 0.001) Kesimpulan: Terdapat hubungan yang bermakna antara stadium tumor dengan metastasis dan jenis tindakan operasi. Tidak terdapat perbedaan bermakna antara kejadian rekurensi lokal dan metastasis serta luaran fungsional dengan jenis tindakan operasi.

ABSTRACT
Introduction: Giant cell tumor of bone is benign lesion with ability to be locally aggressive in epiphysis. Its recurrence rate was reported as high as 75%. Tumor can metastasize to lungs (2-9%) and up to 37% mortality rate due to metastasis. Several studies have reported different rates of local recurrence, lung metastasis, mortality rate, and functional outcome. This study aims to report our experience and analyze the correlation between surgery and clinical findings. Methods: In this retrospective cohort, 99 patients GCT of bone undergone curettage or wide resection in Cipto Mangunkusumo Hospital during 1995-2014. Oncological outcome were analyzed according to local recurrence rate, metastasis, and mortality rate, while functional outcome were measured according to Musculoskeletal Tumor Society Score (MSTS). Results: Tumor location were predominantly in distal femur (25.2%). Local recurrence were observed in 4 patient and mainly in distal femur (50%). Local recurrence were evenly balanced between surgical curettage and wide resection (50% each) and thus not statistically significant (Exact Fischer, p=0.578). Metastasis were observed in patients who undergone wide resection, however, no significant correlation were found between metastasis incidence and types of surgical intervention (Exact Fischer, p=0.318). Four have died related to metastasis. No local recurrence were observed in patients suffering from metastasis. In more than half of patients (51.5%), the functional status were very good (MSTS >75. Recurrence-free survival analysis not significant statistically (p 0.564).Multivariate analysis (Cox regression) showed that only metastasis was found to be significantly correlated to mortality (p. 0.001). Conclusion: Tumor stage was correlated to metastasis, and type of surgical intervention. No significant correlation were found between local recurrence, metastasis, and functional outcome to types of surgical intervention., Introduction: Giant cell tumor of bone is benign lesion with ability to be locally aggressive in epiphysis.

Abstrak :
Stroke yang disebabkan karena gangguan perfusi otak merupakan penyebab utama disabilitas dan kematian di seluruh dunia. Komplikasi stroke dengan angka mortalitas tinggi yaitu edema luas akibat infark arteri serebri media/middle cerebral artery (MCA) maligna yang kemudian diikuti deteriorasi neurologis cepat dan berujung pada luaran yang buruk dengan angka kematian sebesar 80%. Kraniektomi dekompresi sebagai tatalaksana infark MCA maligna diketahui dapat meningkatkan probabilitas keselamatan hingga lebih dari 80%. Penelitian ini bertujuan untuk mengetahui angka kesintasan dan kualitas hidup pasien infark MCA maligna 1, 3, 6, dan 12 bulan pasca-operasi kraniektomi dekompresi di Indonesia, hubungan luaran dengan terapi reperfusi pendahulu, dan menganalisis faktor-faktor yang telah diketahui dapat mempengaruhi luaran, yaitu usia, waktu pembedahan, dan diameter anteroposterior kraniektomi. Penelitian ini bersifat kohort retrospektif melalui pengambilan data rekam medis pasien infark MCA maligna yang dilakukan tindakan kraniektomi dekompresi di Rumah Sakit Umum Pusat dr. Cipto Mangunkusumo (RSCM), Rumah Sakit Umum Pusat (RSUP) Fatmawati, dan Rumah Sakit Pusat Otak Nasional Prof. Dr. dr. Mahar Mardjono Jakarta (RS PON) pada tahun 2017-2022. Sebanyak 39 subjek masuk dalam kriteria inklusi. Dari seluruh subjek, sebanyak 51,3% subjek berusia <60 tahun, 48,7% dioperasi dalam waktu pembedahan <48 jam, 76,6% memiliki diameter kraniektomi 12-14 cm, dan 38,5% subjek mendapatkan terapi reperfusi pendahulu sebelum operasi. Dari hasil penelitian didapatkan 12 penyintas yang hidup pada akhir follow-up. Angka kesintasan pada bulan pertama sebesar 55% yang kemudian turun menjadi 36% pada 12 bulan follow-up (Kaplan-Meier). Dari 27 subjek yang meninggal, 17 subjek meninggal dalam bulan pertama perawatan pasca-operasi di rumah sakit (rentang 1-20 hari), sedangkan sisanya meninggal di luar perawatan rumah sakit. Penyebab tertinggi kematian yang diketahui yaitu infeksi. Dari 12 penyintas, 58% memiliki luaran fungsional yang buruk (modified Rankin scale 4-5) pada akhir follow-up. Tidak didapatkan adanya perbedaan signifikan angka kesintasan (p 0,779, log rank test) maupun luaran fungsional (p 0,929, Mann- Whitney test) pada kelompok yang mendapatkan terapi reperfusi maupun tidak. Dari analisis bivariat diketahui bahwa faktor usia, waktu pembedahan, dan diameter kraniektomi tidak berhubungan signifikan dengan kesintasan maupun luaran fungsional. Dari analisis multivariat dengan melibatkan faktor-faktor tambahan di luar faktor tersebut, diketahui jenis kelamin berhubungan signifikan terhadap luaran fungsional (p 0,032) sedangkan skor National Institutes of Health Stroke Scale (NIHSS) pra-operasi berhubungan secara signifikan dengan kesintasan (p 0,028) dan luaran fungsional (p 0,004). Dari penelitian ini diketahui bahwa angka kesintasan 12 bulan pasien infark MCA Universitas Indonesia viii maligna yang dilakukan kraniektomi dekompresi yaitu sebesar 36% dan mayoritas penyintas memiliki luaran fungsional buruk. Perlu dilakukan penelitian lebih lanjut dengan menyertakan kelompok kontrol pasien infark MCA maligna yang tidak dilakukan kraniektomi dekompresi namun mendapatkan terapi konservatif maksimal agar dapat diketahui manfaat operasi melalui perbandingan luaran kedua kelompok tersebut. ...... Stroke caused by impaired brain perfusion is a major cause of disability and death worldwide. Stroke complication with high mortality rate is extensive edema due to malignant middle cerebral artery (MCA) infarction which is followed by rapid neurological deterioration and leads to poor outcomes with a mortality rate of 80%. Decompressive hemicraniectomy as a treatment for malignant MCA infarction has been known to increase the probability of survival by more than 80%. This study aims to determine the survival rate and functional outcome of patients with malignant MCA infarction in 1, 3, 6, and 12 months after decompressive hemicraniectomy in Indonesia, analyse impacts of prior reperfusion therapy to outcomes, and also analyse factors that are already known to affect outcome from literatures, which are age, timing of surgery, and anteroposterior craniectomy diameter. This study was a retrospective cohort by collecting medical record data of malignant MCA infarction patients who underwent decompressive hemicraniectomy at Cipto Mangunkusumo National General Hospital, Fatmawati General Hospital, and Mahar Mardjono Jakarta National Brain Center Hospital from 2017-2022. A total of 39 subjects were included, 51.3% of them were aged <60 years, 48.7% were operated within <48 hours of onset, 76.6% had a craniectomy diameter of 12-14 cm, and 38.5% received reperfusion therapy prior to surgery. Results of the study, 12 subjects survived at the end of follow-up. The survival rate at the first month was 55% which then decreased to 36% at 12 months follow-up (Kaplan-Meier). Of the 27 subjects who died, 17 subjects died within the first month of post-operative care in the hospital (interval 1-20 days), with infection as the leading cause of death, while the rest died outside of hospital care. Of the 12 survivors, 58% had poor functional outcomes (modified Rankin scale 4-5). There was no significant difference in survival rate (p 0.779, log rank test) and functional outcome (p 0.929, Mann-Whitney test) in the group receiving reperfusion therapy or not. From the bivariate analysis, it was found that age, timing of surgery, and craniectomy diameter were not significantly related to survival or functional outcome. From the multivariate analysis including other additional factors, it was found that sex was significantly related to functional outcome (p 0.032) while the pre-operative National Institutes of Health Stroke Scale (NIHSS) score was significantly related to survival (p 0.028) and functional outcome (p 0.004). From this study, it is known that the 12-month survival rate of malignant MCA infarction patients who underwent decompressive hemicraniectomy was 36% and the majority of survivors had poor functional outcomes. Further research is needed by including a control group of patients with malignant MCA infarction who did not undergo decompressive hemicraniectomy Universitas Indonesia x but received maximum conservative therapy in order to know the benefits of surgery by comparing the outcomes of the two groups.
