How is localized endometrial cancer staged? Four stages

Endometrial cancer is clinically divided into four stages according to the scope of cancer cell invasion. Stage I is the early stage of the disease, with the lesion confined to the uterus; Stage II is when cancer cells invade the cervix and endocervical canal; Stage III is when cancer cells invade the adnexa, fallopian tubes, ovaries, vaginal wall and other parts; Stage IV is the late stage, with frequent distant metastasis.

Clinically, endometrial cancer is divided into many different types, such as diffuse, localized, and polypoid. Among them, localized endometrial cancer has a smaller range of canceration on the surface and often invades deeper into the uterine wall, causing uterine wall ulcers and perforations, which requires active treatment. However, the treatment methods are different for different stages of the disease, so how is localized endometrial cancer staged?
1. Stage I endometrial cancer <br/>Clinically, endometrial cancer is staged mainly based on the extent of cancer cell invasion. If the lesion is confined to the uterus and has not infiltrated or metastasized to surrounding tissues or distal ends, it is stage I. This is the early stage of the disease. If the lesion can be surgically removed as soon as possible, the five-year survival rate can reach 85%~90%, and the clinical cure rate is very high.
2. Stage II endometrial cancer <br/>When endometrial cancer develops to stage II, the condition is more serious than stage I. Cancer cells or lesions may invade the cervix and affect the cervix and endocervical canal. At this time, surgical treatment is also chosen, and the prognosis is also good. The 5-year survival rate can reach about 70%. It should be noted that it is best to perform lymph node dissection after surgery to remove as many cancer cells as possible and reduce the recurrence rate.
3. Stage III endometrial cancer <br/>When cancer cells invade locally or invade the uterine serosa, appendages, fallopian tubes, ovaries, vaginal walls and other parts, it is stage III endometrial cancer. At this time, the condition is more serious and surgical treatment can be chosen, but postoperative adjuvant radiotherapy and chemotherapy are still needed to kill cancer cells in order to better prolong survival. After the disease develops to stage III, active treatment is required, and the 5-year survival rate is about 50%.
4. Stage IV endometrial cancer <br/>This is the late stage of endometrial cancer. Cancer cells not only invade the bladder and rectum, but also metastasize to distant parts of the body. Metastatic lesions may appear in the lungs, liver, head and other parts. Patients will have obvious discomfort symptoms such as progressive emaciation, weight loss, anemia, etc. The prognosis at this time is relatively poor. If surgical treatment is possible, the five-year survival rate is only 15%; some patients have poor physical constitution and cannot undergo surgical treatment. They can only take radiotherapy, chemotherapy or take Chinese medicine to prolong their survival.
