Main stages and surgical options (primary and interval)
In modern oncology, two main surgical options are used.
| Criteria | Primary cytoreductive surgery | Interval cytoreductive surgery |
|---|---|---|
| When used | Before drug therapy | After several courses Chemotherapy |
| What it evaluates and records | Initial extent of the disease | Tumor response to therapy |
| Advantages | Rapid removal of the main tumor mass | Less interventional scope |
| Limitations | Higher technical complexity | Requires strict adherence to treatment schedules |
| When it is chosen | When complete cytoreduction can be achieved | When the disease has spread significantly |
The choice of method depends on the prevalence of the disease, the patient's overall condition, and the prognosis.
What are cytoreductive surgeries in oncology?
This is a surgical procedure aimed at removing as much of the tumor mass and visible foci of disease spread as possible. This approach is used in situations where classic radical removal is impossible due to the extent of the disease.
What is the essence of tumor mass reduction?
The main goal of the procedure is to achieve maximum tumor volume reduction and reduce the number of active tumor cells in the body.
The less tumor tissue remains, the greater the sensitivity of the disease to drug treatment. This is why cytoreductive surgery often becomes the basis of combination therapy.
In some cases, the procedure helps eliminate complications associated with tumor growth: intestinal obstruction, severe pain, disruption of internal organs, and tumor intoxication.
How is cytoreduction different from radical tumor removal?
During radical surgery, the doctor aims to completely remove the tumor within the healthy tissue.
Cytoreduction is used in more complex situations, when the disease has already spread beyond the primary tumor. The surgeon removes as much diseased tissue and metastases as possible.
This tactic helps improve the effectiveness of subsequent systemic therapy and increases the chances of prolonging survival in cancer patients.
