Abstract

This study was made to determine the
clinical and pathological features and incidences of tumors according to the
results obtained from the samples taken during an appendectomy, to evaluate the
post-diagnosis treatments and the survival time of patients. The data of this
retrospective study had from the files of 4813 patients who were operated with pre-diagnosis
of acute appendicitis at Ankara Atatürk Training and Research Hospital between
2007,-2017. Fifteen (0.31%) of the patients who underwent appendectomy were
detected to have appendix tumors. According to the histopathological
classification of tumors of these patients, it was determined that 8 of them
had a carcinoid tumor, 6 of them had mucinous adenocarcinoma and 1 of them had
adenocarcinoma. The mean age of the patients with carcinoid tumor was 30.29 ±
7.95 and the mean age of the patients with mucinous adenocarcinoma was 65 ±
18.81. It has been determined that women develop two times more appendix tumors
than men. Nine patients with a tumor diameter less than 1 cm had only
appendectomy operation and it was determined that tumors did not recurrence
after the follow-up. Three patients with postoperative mesoappendix involvement
underwent right hemicolectomy in the second operation. Preoperative computed
tomography revealed periappendicular mass in 3 patients. In addition to right
hemicolectomy, omentectomy, peritonectomy and lymph node dissection were
performed in these three patients with suspected malignancy. The five-year
survival of patients was found to be 100.0% in patients with carcinoid tumors
and 67.0% in patients with mucinous adenocarcinomas. In conclusion, the majority
of appendiceal tumors in our study that were found to be more widespread in
women than in men were detected incidentally. The prognosis and survival rates
of patients with carcinoid tumors were better than mucinous adenocarcinomas.
Therefore, to made follow-up and treatment of the patients according to the
report obtained after histopathologic examination of the appendix tumor is
important.

Apendiks Tümörlerinin İnsidansı, Tedavisi ve Sağ Kalım: Retrospektif Bir Çalışma

Abstract

Bu
araştırma, appendektomi sırasında alınan numunelerden elde edilen sonuçlara
göre tümörlerin klinik ve patolojik özelliklerini ve insidanslarını belirlemek,
tanılama sonrasında yapılan tedavileri ve hastaların sağ kalım sürelerini
değerlendirmek amacıyla yapılmıştır. Retrospektif olarak yapılan bu
araştırmanın verileri, 2007-2017 yılları arasında Ankara Atatürk Eğitim ve
Araştırma Hastanesi’nde akut apandisit ön tanısıyla opere edilen 4813 hastanın
dosyasından elde edilmiştir. Appendektomi yapılan hastaların 15 (%0,31)’inde
appendiks tümörü olduğu saptanmıştır. Bu hastaların tümörlerinin histopatolojik
sınıflandırmaya göre 8’inde karsinoid tümör, 6’sında müsinöz adenokarsinom ve
1’inde adenokarsinom olduğu belirlenmiştir. Karsinoid tümörlü hastaların yaş
ortalaması 30.29±7.95, müsinöz adenokarsinomlu hastaların yaş ortalaması 65±18.81
olarak saptandı. Kadınlarda erkeklere göre iki kat daha fazla appendiks
tümörünün geliştiği tespit edilmiştir. Tümör çapı 1 cm’den küçük olan 9 hastaya
sadece appendektomi operasyonu yapılmış ve takipleri sonrasında tümörlerin nüks
etmediği belirlenmiştir. Postoperatif mezoappendiks tutulumu olan 3 hastaya,
ikinci operasyonda sağ hemikolektomi yapılmıştır. Ameliyat öncesi çekilen
bilgisayarlı tomografide, 3 hastada periapendiküler kitle tespit edildi.
Maligniteden şüphelenilen bu üç hastaya sağ hemikolektominin yanı sıra
omentektomi, peritonektomi ve lenf nodu diseksiyonu operasyonu
gerçekleştirilmiştir. Hastaların beş yıllık yaşam süresi kasinoid tümörü
olanlarda %100 iken, müsinöz adeno karsinomlarda %67 olduğu saptanmıştır. Sonuç
olarak, araştırmamızda kadınlarda erkeklere göre daha fazla görüldüğü saptanan
appendiks tümörlerinin çoğunluğu rastlantısal olarak tespit edilmiştir. Karsinoid
tümörlü olan hastaların prognozu ve hayatta kalım oranları, müsinöz adeno
karsinomlulara göre daha iyi olduğu belirlenmiştir. Bu nedenle appendiks
tümörün histopatolojik incelemesi sonrasında elde edilen rapora göre hastaların
takibinin ve tedavisinin yapılması önemlidir.
