— What is surgical oncology capable of nowadays?
— Surgical oncology is currently at its height. Thanks to advancements in diagnostics, we are now detecting localized tumors more frequently and have mastered the art of delicately removing small tumors. Hence, there is a significant trend in oncology towards using organ-preserving treatment methods that maintain the functions of the organ. This includes tumors in the kidneys, stomach, lungs, bones, and even remarkable surgeries on the spine that preserve spinal functions. Patients who were previously unable to move their legs can rise post-surgery, like Lazarus, with restored functions of their lower limbs and pelvic organs. This trend has a profound impact on improving patients' quality of life.
— Have robots ever assisted you during surgeries?
— Yes, for instance, during prostatectomies for patients with prostate cancer or during kidney resections in patients with kidney cancer. Nowadays, many patients insist on being operated on by a robot, believing that robots are the future of surgery. However, the reality is that the surgeon still performs the operation, and only a specifically trained surgical oncologist surgeon can properly remove a tumor.
— How does a surgeon collaborate with a robot during surgery?
— Whether you eat porridge with your hands, a spoon, or chopsticks, these are just different methods of getting food into your mouth. The same principle applies to surgical methods. We have the option to make a large cut, hold the tool in our hands, and look down in the wound. This is referred to as open surgery. Alternatively, we can create small punctures in the body, insert a camera and tool into the cavity, and perform the operation endoscopically while looking at a monitor.
Or, we can operate from a robot control console, where the robot will hold the camera and surgical tools. The surgeon's hands are limited in terms of angle, but the robot's “arms” can rotate the instruments at any angle, providing us with great maneuverability and the ability to perform complex manipulations. Another significant detail is that this method allows us to see nerves and vessels that we would otherwise have to bypass blindly during open surgery. It's simply revolutionary!
— What other techniques are available to modern oncology?
— Oncology originated from surgery. Because the simplest possible action is to mechanically remove the malignant tumor. However, a tumor can only be completely removed when it is operable and when we talk about one piece, one tumor. At most, there can be two of them. In other cases, attempts at radical surgical treatment can be likened to torture. It is as difficult as trying to rid a dog of fleas by catching each one individually.
What is necessary is a systemic approach that suppresses all tumor cells. This concept guided the development of drug therapy in oncology, also known as chemotherapy. The goal is to find drugs that only target rapidly growing cells. Chemotherapy continues to be widely used and beneficial to the patients, but it affects too broad a spectrum by destroying not only tumor cells but also bone marrow cells, hair follicle cells, and so on.
Therefore, alternative methods of systemic tumor targeting were sought. It was discovered that some tumors are influenced by the patient's hormone profile. The most notable examples are breast cancer and prostate cancer, for which hormone therapy was developed. Then a new discovery appeared. Scientists learned that if certain proteins produced on the surface of tumor cells are "switched off", the tumor cells will cease to grow and multiply. This led to the development of targeted therapy.
