Endoscopic ultrasound-guided fine-needle aspiration results in upper gastrointestinal system mesenchymal tumors
Öz
Background and Aims: Gastrointestinal mesenchymal tumors have characteristic
endoscopic and endosonographic imaging findings, whereas endoscopic
biopsies are usually not helpful for diagnosis. Endosonography-guided
fine-needle aspiration biopsy might allow the procurement of samples
from the lesion. We report retrospective results and efficiency of endosonography-
guided fine-needle aspiration in upper gastrointestinal mesenchymal
tumors. Materials and Methods: Patients admitted to our endosonography
unit with pre-diagnosis of upper gastrointestinal system mesenchymal
tumors between 2009 and 2010 were evaluated. Patients who underwent
endosonography-guided fine-needle aspiration (n=27) were included in the
study. The cytopathology specimens were evaluated by two blinded pathologists.
The final diagnoses were recorded. Results: Eighteen male and 9 female
patients with a mean age of 52.6±12.1 years (30–84 years) were included
in the study. Lesions were located in the esophagus in 14 patients and in
the stomach in 13 patients. The mean lesion diameter was 29.5±15.6 mm
(7-57 mm). Endosonography-guided fine-needle aspiration procedures were
performed by two gastroenterologists. Cytopathology specimens were evaluated
and the presence of spindle cells was reported in 14 samples (51.8%).
Out of 14 samples, two were reported as malignant gastrointestinal stromal
tumors, whereas 4 specimens were reported as suspicious for mesencymal
tumors. Immunohistochemistry for CD117 was applied to nine specimens
and two samples were positive. Malign gastrointestinal stromal tumor was
reported in two patients. Those two patients also had pathologic lymph node
metastasis and endosonography-guided fine-needle aspiration was applied
to the lymph nodes as well. Repeated endosonography-guided fine-needle
aspiration was applied to three samples and with repeated fine-needle aspiration,
the overall diagnostic efficiency of endosonography-guided fine-needle
aspiration in upper gastrointestinal mesencymal tumors reached 59.25%.
Conclusion: Endosonography-guided fine-needle aspiration supports the
diagnosis of mesencymal tumors in 51.8% of patients. With repeated endosonography-
guided fine-needle aspiration , the diagnostic yield was 59.25%.
Although endosonography is very helpful in the diagnosis of mesencymal
tumors, endosonography-guided fine-needle aspiration adds less to the definite
diagnosis.

Üst gastointestinal sistemde mezenkimal tümör düşünülen olgularda endosonografik ince iğne aspirasyon biyopsi sonuçları
Öz
Giriş ve Amaç: Gastrointestinal mezenkimal tümörler belirgin endoskopik
ve endosonografik özelliklere sahip olmalarına karşın histopatolojik tanıda
endoskopik biyopsinin başarısı düşüktür. Endosonografik ince iğne aspirasyon
biyopsisi lezyonlardan daha derin örnekleme olanağı sağlayan bir yöntemdir.
Bu çalışmada retrospektif olarak üst gastrointestinal sistem mezenkimal
tümörü düşünülen ve endosonografik ince iğne aspirasyon biyopsisi
uygulanan olguların sonuçları irdelenmiştir. Gereç ve Yöntem: Çalışmaya
2009-2010 yıllarında kliniğimize başvuran ve üst gastrointestinal sistem mezenkimal
tümor şüphesi ile endosonografik ince iğne aspirasyon biyopsisi
uygulanan 27 vaka dahil edilmiştir. Olgularda tanımlanan lezyonlardan alınan
endosonografik ince iğne aspirasyon biyopsisi materyalleri sitopatolojik
incelemeye gönderilmiştir. Materyaller iki ayrı patolog tarafından değerlendirilerek
materyalin yeterliliği ve tanı bildirilmiştir. Bulgular: Çalışmaya
yaş ortalaması 52.6±12.1 yıl (30-84 yaş aralığında) olan 18 erkek, 9 kadın
dahil edilmiştir. Lezyonların 14’ü özofagus, 13’ü midede yer almaktadır ve
ortalama çap 29.5±15.6 (7-57 mm) ölçülmüştür. Lezyonlara uygulanan endosonografik
ince iğne aspirasyon biyopsisi sonucu elde edilen materyalin
sitopatolojik incelemesinde 14 adedinde (%51.8) iğsi hücreler görülmüştür.
Bunlardan 2 olguda malign davranışlı gastrointestinal stromal tümör tanısına
ulaşılmış, 4 olguda mezenkimal tümor açısından kuşkulu sitoloji bildirilmiş,
kalan 8 olguda iğsi hücre toplulukları görülmüştür. Dokuz olguda hazırlanan
hücre bloklarına immünohistokimyasal olarak CD117 boyası uygulanmıştır.
Malign gastrointestinal stromal tümör tanısına ulaşılan olgularda
midede mezenkimal kitle ve perigastrik lenf nodu metastazı saptanarak her
iki lezyona endosonografik ince iğne aspirasyon biyopsisi uygulanmıştır. Üç
olguya ikinci kez biyopsi uygulanmış ve iki olguda iğsi hücreler görülmüştür.
Bu olgularla birlikte tanı oranı %59.25’e ulaşmıştır. Sonuç: Gastrointestinal
mezenkimal tümörlerde endosonografik ince iğne aspirasyon biyopsisi,
tanıyı %51.8 olguda destekler bulgular vermiş, iki olguda malign gastrointestinal
stromal tümör tanısına ulaşılmıştır. Tekrarlayan endosonografik ince
iğne aspirasyon biyopsisi ile tanı oranı %59.25’e ulaşmıştır. Sonuç olarak
üst gastrointestinal mezenkimal tümörlerde endosonografik inceleme oldukça
yararlı iken endosonografik ince iğne aspirasyon biyopsisi tanıya yeterli
katkı sağlamamaktadır.
