[SEM study of invasive characteristics of colorectal cancer].
This paper reports the results of a study on the invasive characteristics of 22 colorectal cancer by scanning electron microscopy (SEM). The results showed that adenocarcinoma cells stretching polymorphic pseudopodia penetrated into peripheral tissue and adhered to or invaded the vessels, but most of the mucoid carcinoma cells migrated separately into the tissue clefts and invaded the vessels. The invasive mode had dominant differentiation in two typical cancer. The author believes that colorectal cancer possesses two invasive factors: ameboid movement and destroying tissues by lysozyme.
