The most common route of cervical cancer metastasis is

The most common metastasis route of cervical cancer is lymphatic metastasis, followed by direct spread, hematogenous metastasis and implantation metastasis. Cervical cancer metastasis pathways mainly include lymphatic metastasis, direct spread, hematogenous metastasis, implantation metastasis, etc.

1. Lymphatic metastasis

Lymphatic metastasis of cervical cancer is the most common way of metastasis. Cancer cells spread to pelvic lymph nodes through the rich lymphatic network around the cervix. In the early stage, it may metastasize to the obturator lymph nodes and internal iliac lymph nodes, and in the late stage, it may involve the para-aortic lymph nodes. Lymphatic metastasis is related to the depth of tumor invasion and degree of differentiation, and can be assessed by pelvic contrast-enhanced CT or PET-CT. Paclitaxel injection combined with cisplatin injection is commonly used clinically for chemotherapy, and when necessary, combined with radiotherapy to control metastases.

2. Direct spread

Cervical cancer can directly infiltrate and spread to adjacent tissues and organs, involve the uterine body upward, invade the vagina downward, and spread to both sides to the cardinal ligament and uterosacral ligament. It can invade the bladder forward and the rectum backward. Patients with advanced disease may develop vesicovaginal or rectovaginal fistulas. Magnetic resonance imaging can clearly show the extent of local infiltration. Treatment requires radical surgery or simultaneous radiotherapy and chemotherapy based on the stage.

3. Hematogenous transfer

Hematogenous metastasis mostly occurs in advanced cervical cancer, and cancer cells metastasize to distant organs through blood circulation. Common metastasis sites include the lungs, liver, bones, etc., which may cause symptoms such as cough, pain in the liver area, and pathological fractures. Diagnosis relies on chest CT, bone scan and other examinations, and treatment is mainly based on systemic chemotherapy, such as nedaplatin injection combined with gemcitabine injection, combined with targeted drugs such as bevacizumab injection to control the progression of the disease.

4. Planting transfer

The detachment, transplantation and metastasis of cancer cells are more common in advanced cervical cancer. They can be planted in the pelvic peritoneum, omentum and other parts of the body, forming multiple metastatic nodules. Patients may have symptoms such as ascites and intestinal obstruction, and laparoscopy can confirm the diagnosis. Treatment needs to be combined with intraperitoneal infusion chemotherapy, such as carboplatin injection, and intravenous chemotherapy to control intraperitoneal dissemination. The prognosis of implant metastasis is poor and multidisciplinary treatment is required.

Cervical cancer patients should regularly review tumor markers and imaging examinations to monitor metastasis. Maintain a balanced diet, properly supplement high-quality protein such as fish and eggs, and avoid spicy and irritating foods. Carry out moderate aerobic exercise according to your physical condition, such as walking, Tai Chi, etc. Strictly follow the doctor's instructions to complete radiotherapy and chemotherapy, and seek medical attention promptly if symptoms such as abnormal bleeding and pain occur. Psychological counseling can help relieve anxiety, and family members should provide adequate support.
