Abstract:
objective To investigate the clinicopathological features of mini-cancer of the stomach. Method In this study,out of 296 early gastric cancer cases there were 34 cases of early gastric cancer in which tumor diameter was≤10 mm,among those there were 5 cases with tumor size≤2 mm and 29 cases of the size 2~10 mm. Result Mini-cancer accunted for 2% of all early gastric cancers in this series:All these mini-cancers were of intramucosal cancer(100%),while that took up to 45%in control group in which tumors were between≥2 mm and≤10 mm:Tumors were high or moderately differentiated pathologically in 100%of mini-cancers and 55%in control group.None of mini-cancer patients had lymph node metastasis,however,1 of 29 patients in control group had lymph node metastasis.Both groups had no blood vessel and lymphatic vessel invasion:The differentiation concordance rate between superficial lesions and invasive fronts in mini-cancer was 100%,higher than 86%in control group. Conclusion Gastric mini-cancer is usually of high differentiation,low tumor invasion and low rate of lympy node metastasis than control group.Endoscopic therapy is applicable for most gastric mini-cancers.
