Rectal cancer is a tumor of the distal (lower) part of the intestine. It is a more severe disease compared to tumors of other parts of the large intestine. However, the disease is successfully treated abroad with surgery, radiation therapy, and drug therapy. In cases of rectal cancer recurrence or contraindications to standard treatment, chemoembolization may be used. It is a minimally invasive endovascular procedure during which the malignant tumor is deprived of blood supply by closing the lumen of the blood vessels.

How is rectal cancer treated?
Surgery is the best treatment option and the only method that gives a chance for a complete cure of the pathology. For rectal cancer treatment in Germany, doctors may perform endoscopic resection, surgical transanal excision, laparoscopic resection, or Da Vinci treatment (robot-assisted surgery).
Whenever possible, anastomosis is applied immediately after tumor removal to restore bowel continuity with the possibility of independent defecation. However, complications during initial treatment often necessitate the use of a colostomy (an opening in the abdomen for fecal diversion). After a few months, a second operation for colostomy closure is performed.
For advanced cancers that have spread throughout the peritoneum, cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) may be used.
At the same time, up to 20% of cases of rectal cancer are detected at an inoperable stage. Moreover, many patients have cancer recurrence after surgery, radiation therapy, and chemotherapy. Only a few of them are considered candidates for revision surgical treatment. Doctors usually use only palliative procedures (endoscopic dilation in stenosis) and systemic therapy (chemotherapy, personalized targeted therapy, and immunotherapy).
Doctors in developed countries also use embolization and chemoembolization. These are effective methods of local tumor control. These procedures are used in patients for whom surgery and radiation therapy are contraindicated.
What are embolization and chemoembolization?
Embolization is a minimally invasive procedure to close the lumen of the arteries that supply blood to the tumor. It is performed to shrink the size of the tumor and eliminate rectal bleeding. The mechanism of antitumor effects is based on depriving the tumor of blood supply because cancer cells die from lack of oxygen.
Regional chemotherapy may enhance the effect of embolization. In such a variant, this procedure is called chemoembolization.
The treatment is performed using a minimally invasive method. Under local anesthesia, doctors make an incision in the groin, insert a catheter, and guide it to the tumor blood vessels. They use a contrast agent to see which arteries are supplying blood to the tumor. These blood vessels are closed with emboli. The blood flow is then checked again. If all the arteries are closed properly, the procedure is complete. If there is still blood flow, the embolization is repeated with larger particles.
Chemoembolization is performed using different methods. This may involve the separate administration of embolisate and chemotherapy drugs, but drugs may also be contained in drug-saturated microspheres.
Conventional transarterial chemoembolization is abbreviated as TACE. Doctors also use various embolization options involving microspheres, tiny balls saturated with chemotherapy drugs. Some of them subsequently dissolve, while others remain in the blood vessels permanently, causing irreversible embolization. Some microspheres are initially saturated with drugs, while others are saturated at the hospital just before the procedure. Depending on the type of microspheres used and the drugs they contain, the TACE procedure may have different names. For example:
- DSM-TACE (degradable starch microspheres)
- DEBIRI-TACE (irinotecan-saturated microspheres, a common chemotherapy drug for treating bowel cancer)
- DEB-TACE (doxorubicin-saturated microspheres)
Some studies show that the use of microspheres is a more effective treatment method for colorectal cancer than conventional chemoembolization, increasing the objective response and survival rates of patients. In addition, the use of microspheres improves the tolerability of the procedure and the rehabilitation period compared to classical chemoembolization.
When can chemoembolization be used for rectal cancer?
In cases of rectal cancer, embolization can be used for:
- Rectal blood vessels
- Liver blood vessels, where metastases of rectal cancer often occur
Chemoembolization is more often performed as part of metastasis-directed therapy. The procedure to close the branches of the hepatic artery has been used in medicine for ten years. It is very successful due to the peculiarities of the blood supply to the liver, as healthy tissue receives nutrition from the portal vein and metastases from the hepatic artery.
Liver metastases may appear synchronously with the primary tumor and be detected during the primary diagnosis. In such cases, chemoembolization can be combined with surgical treatment when the rectal tumor is removed and liver metastases are controlled through an endovascular procedure.
Liver metastases may also be detected later, as a rectal cancer recurrence, after the removal of a fragment of the rectum. In such cases, chemoembolization can be used as the main or only treatment method, especially in conditions where liver resection is impossible or contraindicated.
Rectal arterial chemoembolization is less common. It is mainly used to stop bleeding. Less commonly, rectal cancer chemoembolization in Germany is performed for tumor control, but it is not yet considered a standard procedure, so it is used as part of clinical trials. Some of these trials show promising results.
One of the studies showed that chemoembolization with microspheres for inoperable patients or patients with recurrent rectal cancer resulted in at least stabilization of the disease and an arrest of tumor growth. In a third of cases, the size of the tumor shrinks to the point where it becomes resectable (can be removed surgically). Although there was no control group in this study, according to the literature, the median survival rate of such severe patients is 6 months. Therefore, the authors considered the treatment results to be outstanding.
In addition to affecting tumor size and survival rate, the chemoembolization also improves quality of life. It alleviates pain, reduces hemorrhage, and decreases the risk of bowel obstruction and defecation disorders. Patients are less likely to suffer from anemia and lose less weight. General symptoms such as weakness, nausea, depression, anxiety, drowsiness, poor appetite, malaise, and shortness of breath are also alleviated.
