ABSTRAK Pendahuluan Penggunaan megaprostesis sebagai pilihan dalam manajemen LSSmemberikan harapan baru bagi pasien tumor tulang di Indonesia. Namun, sampaisaat ini belum ada data hasil luaran dari tata laksana ini.Metode Penelitian ini merupakan prospektif observational pada 34 pasien tumortulang di RS Cipto Mangunkusumo pada tahun 2011-2015. Diagnosis ditegakkanmelalui Clinical Pathological Conference. Evaluasi pascaoperasi dilakukan padabulan ke-3, 6, 9, 12, 24, 36, dan 48 dengan menggunakan skoring dari MSTS.Luaran onkologi dievaluasi dengan adanya rekurensi dan metastasis jauh.Komplikasi berupa infeksi, dislokasi, cedera saraf dan pembuluh darah, sertagangguan mekanisme ekstensor juga dievaluasi. Hasil Dua orang ahli bedah muskuloskeletal onkologi melakukan operasi LSS danrekonstruksi dengan megaprostesis. Dua pasien dieksklusi karena keputusanintraoperatif untuk memakai non modular endoprostesis. Kehilangan darahintraoperatif memiliki median (RAK) 890,0 (700,0?1200,0) ml. Skor MSTSsebagian besar pasien menunjukkan kategori baik dan sangat baik, yaitu 67.9%baik pada MSTS 6 bulan, 79,2% baik pada MSTS 9 bulan, 63.4% sangat baikpada 12 bulan, 90% sangat baik pada 24 bulan dan 100% sangat baik pada MSTS36 bulan. Terdapat hubungan bermakna antara karakteristik pasien yaitu jenistumor (p=0,001), usia (p=0,039), jenis kelamin (p=0,049), dan hasil laboratoriumALP (p=0,031) dengan luaran fungsional MSTS 3 bulan. Terdapat hubunganbermakna antara karakteristik pasien yaitu perdarahan intraoperatif (p=0,013) danALP (p=0,009) dengan mortalitas; dan juga antara tumor tulang yang menjalanirekonstruksi jaringan lunak ekstensif dengan komplikasi (p=0,019) namun antaralokasi tumor dan komplikasi tidak terdapat hubungan bermakna. Kesimpulan Luaran fungsional pada pasien yang dilakukan rekonstruksimegaprostesis adalah baik dan sangat baik sehingga dapat menjadi tatalaksanapilihan bagi pasien tumor tulang yang akan menjalani LSS. Luaran onkologi padapasien yang dilakukan prosedur LSS baik dengan rendahnya rekurensi lokal, metastasi, dan komplikasi. ABSTRACT Introduction Advancement in bone tumor management has elaborated surgeon?schoice of treatment not merely sentenced the patients into a limb ablation.Likewise, patients with bone tumors, regardless its malignant nature and limitedsurvival time, had an equal privileges to opt for LSS to experience a better qualityof life. In this study, we manage to evaluate the functional and oncologic outcomeof lower extremity bone tumors following a LSS using megaprosthesis. Methods Thirty-four patients with lower extremity bone tumors wereprospectively reviewed between 2011 and 2015 in a tertiary referral generalhospital. All patients were managed through a Clinical Pathology Conference.Functional outcome was evaluated using MSTS score and follow up was recordedat 3, 6, 12 months; and 2, 3, 4 years.Results Two orthopedic musculoskeletal oncologic surgeons were performing thesurgeries. Two patients were excluded because the final instruments used werenot a modular type. The final result of functional score was good to excellent with67.9% good at 6 months, 79,2% good at 9 months, 63.4% excellent at 12 months,90% excellent at 24 months and 100% excellent at 36 months. Complicationsoccurred and varied. A statistical significant result was found between age(p=0,001), age (p=0,039), gender (p=0,049), SAP (p=0,031) and 3 monthsfunctional outcome; between intraoperative blood loss (p=0,013) and mortality,as well as SAP with mortality (p=0,009); between tumor that underwent extensivesoft tissue reconstruction procedure and complication (p=0,019).Conclusion Megaprosthesis reconstruction in bone tumors gives a good andexcellent result, which provides orthopaedic oncologic surgeons a rationalizationto make a selective decision-making in tumor cases regardless its survival andtumor type. Oncologic outcome as well gave out good result with low incidence of far metastasis and local recurrence.;Introduction Advancement in bone tumor management has elaborated surgeon?schoice of treatment not merely sentenced the patients into a limb ablation.Likewise, patients with bone tumors, regardless its malignant nature and limitedsurvival time, had an equal privileges to opt for LSS to experience a better qualityof life.
