Minimally invasive interventional techniques are the epitome of high-tech tumor treatment in recent years, and local ablation, vascular embolization and particle implantation are its most outstanding representatives. Local ablation technology mainly includes radiofrequency, microwave, laser, argon helium knife freezing, ultrasonic focused knife, etc. It is to puncture the tumor percutaneously under the guidance of ultrasound, CT and other images, or to puncture the tumor with the assistance of laparoscopy, open abdomen and other surgical means, to cause coagulative necrosis of the tumor through high temperature or low temperature, and then achieve the goal of complete elimination of the tumor. Minimally invasive oncology department of Shandong Qianfo Mountain Hospital Zhao Wenhua Currently, it has been widely used in the treatment of benign and malignant tumors of liver, lung, kidney, bone, thyroid, breast, lymph nodes and other solid organs, and is another emerging treatment means with tumor cure potential after surgical resection. Compared with traditional surgical resection, local ablation not only has the thoroughness of surgical resection, but also has less damage, faster treatment, simpler operation, faster recovery, higher quality of life, almost no long-term sequelae and can be applied for many times. Particle implantation, on the other hand, is to implant radioactive particles evenly in the tumor by percutaneous puncture under image guidance, and kill the tumor cells by the radiation emitted by the particles themselves. Compared with conventional radiotherapy (external irradiation), it is a simpler operation, shorter treatment time (basically one-time), less side effects and faster recovery, and is the best alternative or supplement to conventional radiotherapy. Undoubtedly, minimally invasive interventional techniques pay more attention to the protection of healthy tissues, respect the quality of life and aesthetic value, strongly expand the indications for solid tumor cure, significantly improve the safety of treatment, and are perhaps one of the minimally invasive treatments in the true sense. (a) Traditional surgical resection is no longer the only means to obtain a cure for tumors. Due to the birth and popularity of many minimally invasive interventional techniques and systemic treatments, losing the chance of surgery is no longer the end of the world, and minimally invasive interventional treatments such as local ablation and particle implantation can also achieve the expected therapeutic effect. Surgical resection (including minimally invasive surgery) and minimally invasive interventional treatment are not competitive or even hostile to each other, but should build on their strengths and avoid their weaknesses, and be mutually inclusive and joint. For example, for liver cancer in high-risk sites, laparoscopic-assisted radiofrequency ablation can ensure the effectiveness of treatment as well as maximize the safety of treatment. For example, if laparoscopic resection of gastrointestinal tumor with liver metastasis is combined with radiofrequency ablation to resolve intrahepatic metastases, patients will get the most benefit from the combined application of the two minimally invasive technologies. (2) There are many tumor treatment methods, there is no which one is the best, only the most reasonable. The treatment must be individualized and integrated according to the specific conditions of patients and tumors; the selected treatment modality must follow the principles of exact efficacy, simple operation, quick treatment process, mild trauma, high quality of life and economic frugality. Surgeons may love surgical resection, while non-surgeons may prefer minimally invasive intervention, chemotherapy or radiotherapy, but with a high degree of responsibility to patients, we must break the boundaries of the profession and technical barriers. As the division of labor in modern medicine becomes more and more detailed, each doctor must not only be proficient in his or her own specialty, but also keep abreast of the latest advances in related treatments. Doctors who are stagnant, old-fashioned and exclusive often become the biggest killers of tumor patients. (3) The division between “early” and “late” stage of tumor is outdated and must be revised. The traditional view is that once the tumor metastasizes to other parts, it can be diagnosed as “advanced stage”, at this time it is not appropriate to take radical treatment such as surgical resection, but can only choose palliative treatment such as endless radiotherapy and chemotherapy, and everything is “left to fate”. With the birth and perfection of minimally invasive interventional technology, patients with “advanced” stage tumors and no chance of surgery have regained hope for cure. For example, a liver tumor with lung metastasis, regardless of the degree of metastasis, was previously referred to as “advanced” and the option of liver resection was largely ruled out. But now we will have more options, such as eliminating the metastases in the lung by ablation or particle implantation, and resolving the intrahepatic tumor by surgical resection or ablation, and patients will still have a chance of long-term survival, because after all, it is not the limited metastases in the lung but the intrahepatic tumor that threatens the length of life of patients. Therefore, for tumor metastasis one must distinguish the degree of metastasis and whether it involves vital organs such as liver, skull and brain or non-vital organs such as lymph nodes and bones. If the patient is predicted to have more than six months of survival, it is necessary to choose the interventional treatment such as local ablation and particle implantation, which are effective and less invasive, so that the patient can have a chance to obtain long-term survival with high quality of life. (4) To uphold the “constructive treatment model” and new concept of “destruction” and “protection” of tumor. Since minimally invasive image-guided treatment can achieve good outcome and prognosis compared with traditional treatment, and has higher safety, simplicity, speed, repeatability and quality of life, is it still necessary for us to indiscriminately adopt highly invasive treatment methods? The concept of “constructive treatment model” was first proposed by Professor Wu Peihong of the Cancer Hospital of Sun Yat-sen University in Guangzhou 10 years ago, which believes that while effectively treating tumors, patients’ physiological functions should be protected to the greatest extent, immune functions should be protected and improved, and quality of life should be protected and improved to the greatest extent. The focus is on minimally invasive, humanized and individualized tumor treatment. Putting it in today’s perspective, this rather forward-looking new concept of tumor treatment has reasons to be the future purpose of tumor treatment. In conclusion, the continuous introduction of new minimally invasive interventional techniques and high-efficiency and low-toxicity drugs is the solid foundation for the revolutionary change of tumor treatment concept. It is expected that medical workers in the field of tumor treatment will be brave to carry out new technologies and embrace new concepts, so that more tumor patients can welcome their own brilliant tomorrow with dignity.
