Stage IIA rectal cancer belongs to intermediate stage cancer, which is easier to recur and metastasize than early stage cancer.
Stage IIA rectal cancer means that the lesion has broken through the mucous membrane layer and submucous membrane layer, and can penetrate into the intrinsic muscular layer, subplasma membrane, or invade the pararectal tissues without peritoneal coverage, and at this time, most of the time there are no lymph nodes or metastasis to other organs.
In stage IIA rectal cancer, lymph node metastasis occurs most frequently, and upper rectal cancer can metastasize to the lymph nodes around the inferior mesenteric artery, superior rectal artery, and abdominal aorta, and the 5-year survival period of such patients after surgery is generally around 70%, and the recurrence degree is more likely to recur compared with early stage cancer, while the chance of recurrence is lower compared with advanced stage cancer.
When rectal cancer occurs, patients should actively consult the doctor and follow the doctor’s instructions for reasonable treatment.
