Abstract

Background/aims: This study was conducted to analyze the factors related to lymph node metastasis in undifferentiated early gastric cancer and to investigate whether endoscopic resection can be performed. Methods: Three hundred sixty-two early gastric cancer patients who were diagnosed with undifferentiated early gastric cancer and underwent surgery were divided into groups depending on their age, sex, location of tumor, macroscopic findings, presence of an ulcer, histological type, tumor size, depth of invasion, and lymphatic involvement, and the correlations between clinicopathological characteristics and lymph node metastasis were analyzed. Results: Lymph node metastasis was detected in 31 (8.5%) of the 362 patients. Univariate analysis revealed correlations between lymph node metastasis and various factors ranging from patient age, location of tumor, presence of an ulcer, and depth of invasion to lymphatic involvement. However, in multivariate analysis, presence of an ulcer and lymphatic involvement were found to be independent risk factors. After selecting and analyzing only patients with intramucosal early gastric cancer, we found that lymphatic involvement was the only independent risk factor. Conclusions: Though presence of an ulcer is an independent predictive factor for lymph node metastasis before operation in patients with undifferentiated early gastric cancer, caution is required in the interpretation. In addition, clinicopathological characteristics such as histological type and tumor size did not have a significant effect on lymph node metastasis. Therefore, we found that the evidence was insufficient to select endoscopic resection even when there is a small lesion, and we believe that the decision on the use of endoscopic resection for patients with undifferentiated early gastric cancer should be made more carefully when there is an ulcer.

Özet

Amaç: Bu çalışmada erken gastrik kanserde lenf nodu metastazı ile ilişkili faktörlerin araştırılması ve endoskopik rezeksiyona uygunluğun araştırılması amaçlanmıştır. Yöntem: Erken kötü differansiye gastrik kanseri olan ve cerrahi uygulanmış 362 hasta çalışmaya dahil edilmiş ve hastalar yaş, cinsiyet, tümör lokalizasyonu, makroskopik bulgular, ülser varlığı, histolojik tip, tümör boyutu, invazyon derinliği ve lenf nodu tutulumuna göre incelenmiş, klinikopatolojik bulgular ile lenf nodu metastazı arasındaki korelasyonlar araştırılmıştır. Bulgular: Hastaların 31’inde (%8,5) lenf nodu metastazı tespit edildi. Tek değişkenli analizde lenf nodu metastazı ile hasta yaşı, tümör lokalizasyonu, ülser varlığı, invazyon derinliği ve lenfatik tutulum arasında ilişki saptandı. Ancak çok değişkenli analizde ülser varlığı ve lenfatik tutulum varlığı, lenf nodu metastazı ile ilişkili bağımsız risk faktörleri olarak bulundu. İntramukozal erken gastrik kanser olan vakalar seçildiğinde ise lenfatik tutulumun tek önemli risk faktörü olduğu görüldü. Sonuç: Ülser varlığı kötü differansiye erken gastrik kanserli vakalarda lenf nodu metastazını öngörmekte prediktif olmasına rağmen, bu verinin değerlendirilmesinde dikkatli olunmalıdır. Ek olarak, tümörün histolojik tipi ve boyutu gibi klinikopatolojik karakteristiklerin lenf nodu metastazı üzerinde anlamlı etkisi olmadığı görülmüştür. Buna göre, küçük lezyonlarda dahi endoskopik rezeksiyonu tercih etmek için yeterli kanıt mevcut değildir. İnanıyoruz ki, ülserli kötü differansiye erken mide kanserli vakalarda endoskopik rezeksiyonu tercih ederken daha dikkatli olunmalıdır.
