目的 了解小胰癌的病理学特点。方法 回顾性分析自 1980年 4月至 2 0 0 2年 5月经手术治疗的有完整病理资料的小胰癌 (直径 <2cm) 2 0例。结果 2 0例 (10 0 % )均有周围组织浸润 ;15例 (75 % )有周围淋巴结转移 ,5例 (2 5 % )无淋巴结转移 ;按照肿瘤的国际标准分期Ⅰ期 5例 ,Ⅲ期 15例。结论 即使是肿瘤直径 <2cm的小胰癌 ,绝大多数已经发生转移 ,病理分期为Ⅲ期 ,已经不属于早期胰腺癌。因此 ,只有进一步加强对早期胰腺癌的警惕和对高危人群的监测 ,才有可能发现较多的早期胰腺癌 ,改善病人的预后。
Objective To understand the pathological features of small pancreatic cancer. Methods A retrospective analysis of 20 patients with small pancreatic cancer (diameter <2cm) with complete pathological data surgically treated from April 1980 to May 2002 was performed. Results Tissue infiltration was found in 20 cases (100%). There were 15 cases (75%) with lymph node metastasis and 5 cases (25%) without lymph node metastasis. According to the international standard of staging, 5 cases were stage Ⅰ, 15 cases. Conclusions Even the small pancreatic cancer with the diameter of <2 cm has the most metastasis, the stage of the disease is stage Ⅲ, and it is no longer an early pancreatic cancer. Therefore, only further vigilance on early pancreatic cancer and monitoring of high-risk groups will it be possible to find more early-stage pancreatic cancer and improve the patient’s prognosis.
