Gastric Lavage Malignant Cells (yGL) and Hypohemoglobinemia (yAnemia) as New Systems of Tumor Regression Grading and Prognostic Prediction for Gastric Cancer After Neoadjuvant Treatment

Background/Aim: Although reckoned necessary for survival benefit, neoadjuvant chemotherapy (NAC) of gastric cancer (GC) patients has so far provided questionable results. Consequently, searching for new and clearer systems of response to NAC, post-NAC re-evaluation and prognostic prediction appears essential. The purpose of this study was to examine endogastric cytopathology and hemoglobin level count as new features, potentially useful for GC...
