ABSTRAK Pendahuluan: Biopsi jarum inti dianggap memiliki hasil akurasi yang sama
dengan biopsi terbuka dan telah menjadi prosedur rutin untuk menegakkan
diagnosis lesi muskuloskeletal. Namun demikian uji diagnostik biopsi jarum inti
di Rumah Sakit Umum Pusat Nasional Cipto Mangunkusumo (RSUPN CM)
belum dilaporkan. Tujuan dari analisis retrospektif ini adalah untuk mendapatkan
nilai ketepatan diagnosis biopsi jarum inti pada lesi muskuloskeletal.
Metode: Dari Januari 2011 hingga Agustus 2015, semua pasien dengan lesi
muskuloskeletal di RSUPN CM yang menjalani biopsi jarum inti dan eksisi tumor
diidentifikasi dan diambil datanya. Ketepatan diagnosis dianalisis baik untuk
kesimpulan histopatologi maupun kesimpulan clinical pathology conference
(CPC).
Hasil: Sebanyak 86 sampel dikumpulkan dalam penelitian ini. Ketepatan
diagnosis biopsi jarum inti dibandingkan dengan spesimen pasca eksisi adalah
74,4%. Setelah dilakukan CPC, nilai ketepatan menjadi 83,7% dengan sensitivitas
98%, spesifisitas 59%, NDP 87%, NDN 93% (p = 0.00). Ketepatan biopsi jarum
inti setelah pulasan imunohistokimia naik menjadi 84,9% (p = 0,438). Ketepatan
untuk membedakan lesi jinak dan ganas adalah 97,1% (jinak) dan 82,7% (ganas)
(p = 0.00). Ketepatan untuk membedakan lesi primer dan metastasis adalah 97,2%
(primer) dan 85,7% (metastasis) (p = 0.00).
Diskusi: Kami mendapatkan nilai ketepatan biopsi jarum inti yang sedikit lebih
rendah karena dalam penelitian ini dituntut untuk membuat diagnosis sampai
tingkat morfologi (ICD O dan ICD X). Namun demikian, dengan modalitas lain
seperti imunohistokimia dan kesimpulan CPC, ketepatan menjadi meningkat.
Ketepatan diagnosis untuk membedakan lesi jinak-ganas dan primer-metastasis tinggi. Biopsi jarum inti direkomendasikan untuk penegakkan diagnosis lesi muskuloskeletal.
ABSTRACT Introduction: Core needle biopsy is considered to have similar results with open
biopsy in accuracy and already become a routine procedure to establish the
diagnosis of musculoskeletal lesion. However, diagnostic test of core needle
biopsy application in Cipto Mangunkusumo Hospital has not been reported.
Therefore, the aim of this retrospective analysis was to attain the accuracy of
musculoskeletal lesion diagnosis using core needle biopsy.
Methods: From January 2011 to August 2015, all patients with musculoskeletal
lesion in Cipto Mangunkusumo Hospital underwent core needle biopsy and
subsequent tumour excision were indentified and enrolled. Diagnostic accuracy
were calculated for both histopathology and clinical pathology conference (CPC)
conclusion.
Results: A total of 86 samples were indentified and enrolled in this study. The
accuracy of core needle biopsy compared to subsequent excision is 74.4%. With
CPC conclusion, the accuracy is 83.7% with sensitivity 98%, specificity 59%,
PPV 87%, NPV 93% (p=0.00). The accuracy with immunohistochemistry is
84.9% (p=0.438). The accuracy to distinguish benign and malignant lesion is
97.1% (benign) and 82.7% (malignant) (p= 0.00). The accuracy to distinguish
primary and metastatic lesion is 97,2% (primary) and 85,7% (metastatic) (p=
0.00).
Discussion: We found slightly inferior results for core needle biopsy accuracy
compared to literature due to high specificity diagnosis obligatory (ICD O and
ICD X morphology) in our study. However, with other modalities such as
immunohistochemistry and CPC, the accuracy is increased. The accuracy to
distinguish between benign vs malignant and primary vs metastatic lesion is high.
Core needle biopsy is recommended to establish diagnosis for selected musculoskeletal lesions.
