Abstract

Introduction: The most important parameters affecting patient prognosis in gastric cancer are the T stage and regional lymph node invasion. Although it is known that lymph node positive patients have poor long-term survival and recurrence and metastasis rates are higher than patients with lymph node negative, recurrence and metastasis may also develop in lymph node negative patients. Studies have found that the most likely causes of this situation are mictometastases which cannot be detected in routine pathological examination and the inability to remove a sufficient number of lymph nodes. There is no clear consensus regarding the number of lymph nodes to be removed and there are very few studies in the literature on this subject.
