The Study of Morphological Distributions of Lymphatic Vessels in Peripheral Areas of Uterine Cervix Cancer and Metastasis / 医学研究杂志

ABSTRACT

Objective To investigate the metastasis mechanism by observing morphological distributions of lymphic vessels in peripheral areas of the different development of uterine cervix cancer. Methods Cancer tissues from the center, peripheral and normal areas of uterine cervix cancer respectively were collected. The paraffin sections and semithin sections which were stained with HE were applied to those tissues for exploring the configurations and distributions of lymphic vessels of the cancer under a microscope. And the ultrathin sections were applied to those tissues for exploring under a electronic microscope. Results Under the microscope, the basement membrane had been destroyed by cancer cell, which continued to infiltrate interstitial tissue. Lymphic vessels were increased and dilated in peripheral areas of uterine cervix cancer than those in normal areas. Moreover, the walls of lymphic vessels were hazy and broken. Conclusion The increase and morphologic changes of lymphic vessels in peripheral areas of uterine cervix cancer will play an important role in lymphatic metastasis.
