Abstract

Aim: Preoperative magnetic resonance imaging (MRI) is one of the most common diagnostic methods in current rectal surgery. In this study, we planned to investigate the concordance between preoperative MRI findings and postoperative histopathological stage in patients with rectal cancer.Method: Fifty-six patients who underwent rectal cancer surgery between September 2014-November 2016 in Adnan Menderes University Faculty of Medicine, Department of Surgery were included in the study. Preoperative and histopathological T and N stages were compared.Results: Fifty-six patients were included in the study. Mean age was 66.05 years. Tumor location was classified as lower rectum in 29.8%, mid-rectum in 32.3%, and upper rectum in 37.9% of the patients. While positive lymph nodes were found on MRI in 21 cases, only 15 were confirmed by histopathology. Of the 35 cases reported to be lymph node negative on MRI, 19 were confirmed. The sensitivity was 71.4% for positive lymph nodes and 54.3% for negative lymph nodes. As for T stages, there was a statistically significant association between MRI and pathological staging (p=0.049).Conclusion: Although high-resolution MRI is currently one of the first imaging methods used in rectum cancers, additional imaging modalities should be also used there is any doubt about the diagnosis.

Özet

Amaç: Günümüzde rektum cerrahisinde preoperatif dönemde manyetik rezonans görüntüleme (MRG) en çok kullanılan tanı yöntemlerinden birisidir. Çalışmamızda rektum kanserli hastalarda, MRG'nin preoperatif evrelemesi ile histopatolojik evrelemenin uyumunu araştırmayı planladık.Yöntem: Adnan Menderes Üniversitesi Tıp Fakültesi, Genel Cerrahi Anabilim Dalı'nda Eylül 2014-Kasım 2016 tarihleri arasında rektum kanseri nedeniyle ameliyat edilmiş 56 hasta çalışmaya dahil edildi. T ve N değerleri preoperatif ve histopatolojik olarak karşılaştırıldı.Bulgular: Çalışmaya 56 hasta alındı. Ortalama yaşı 66,05 idi. Tümörlerin yerleşim yerine bakıldığında %29,8'i alt rektum, %32,3'ü orta rektum, %37,9'u ise üst rektum olarak gözlendi. MRG'de N(+) 21 olgu saptanırken bunlardan sadece 15'i patolojik olarak da N(+) olarak saptandı. MR'de 35 olgu N(-) saptanırken bunlardan 19'u patolojik olarak N(-) saptandı. N(+)'de duyarlılığı %71,4 iken, N(-)'lerde bu oran %54,3 olarak gözlendi. T değerlerine bakıldığında ise MR ile histopatolojik evreleme arasında istatistiksel bir anlamlılık olduğu gözlendi (p=0,049).Sonuç: Günümüz rektum kanserlerinde preoperatif görüntüleme yöntemlerinden ilk başvurulacaklardan birisi yüksek çözünürlüklü MRG olmakla birlikte, tanıda kuşku duyulması halinde ek görüntüleme yöntemleri de mutlaka kullanılmalıdır.
