Abstract:
Objective To provide the theoretic basis for the clearance of the metastatic lymph nodes in radical operation of colorectal carcinoma(CRC) by means of exploring the relationship between mass size of both tumor and lymph nodes and the rate of lymph node metastasis. Methods A total of 702 lymph nodes from 57 cases of CRC radical operations were divided into 5 groups and each of the lymph nodes was examined. The size of lymph nodes, Dukes' phases, the pathological types of CRC and their metastasis rate were analyzed. Results ① High metastasis rate was found at Dukes' C and D phases of CRC, being 29.93% and 48.12%, respectively. ② The metastasis rates of mucous adenocarcinoma and signet ring cell carcinoma were the highest of all pathological types, being 59 52% and 59.26%, respectively. ③ Metastasis rate of lymph nodes was not correlated with the mass size of tumor, but correlated with Dukes' phase. Conclusion ① Metastasis rate of lymph nodes increases with the growth and infiltration of tumor. ② Metastasis rates of mucous adenocarcinoma and signet ring cell carcinoma are higher than those of well and mid differentiated carcinomas. ③ Metastasis may be suggested for lymph node of CRC more than 5 mm in diameter during operation. However, clearance of lymph node of CRC less than 5 mm in diameter needs further study.
