Introduction

Bronchoscopy PDT to some patients who couldn't have surgery because they had other problems. With a size of around 100 nm, they developed multimodal "porphyrin" nanoparticle-porphyrin-lipid conjugates. Porphyrins, which preferentially accumulate in numerous solid tumors and have a high permeability and retention effect. Additionally, porphyrin is capable of successfully converting light energy into heat energy. As a result, Porphyrin-mediated PTT tumor effectively eliminates subcutaneous tumors in mice without causing recurrence. The majority of surgical patients choose full resection because it has the potential to treat cancer optimally. New surgical instruments have opened up a world of possibilities for complete resection; Patients' survival rates have increased as surgical tumor plans become increasingly precise. Vascular replacement, carinal reconstruction, and so on. The recent proposal of "tubeless surgery" and the continued integration of new technologies into existing thoracoscopic techniques, such as electromagnetic navigation, 3D reconstruction, application of nanotechnology, etc., will continue to have a significant impact on future developments in pulmonary surgery. to accomplish complete resection at a level beyond the visual [1].

Description

Most treatments for solid tumors assume that complete surgical resection can cure the majority of cases, which is impossible in real-world clinical situations. Postoperative recurrence or metastasis is primarily caused by the fact that surgery cannot completely remove all tumors. Most of the time, adjuvant therapy is used before or after surgery to get rid of MRD and make the surgery go better. The macroscopic surgical resection and the microscopic ablation with the aid of photodynamic therapy (PDT) and photothermal therapy (PTT) are the tumor two main components of the tumor surgical procedure. PDT relies on oxygen, light, and a photosensitizer as its three main ingredients. The laser produces cytotoxic reactive oxygen species (ROS) when photosensitizer accumulates in the tumor site. The photothermal effect (PTA) is the basis for mediated tumor killing with PTT. The photothermal transfer agent turns the absorbed light energy into heat when it builds up in tumor the tumor. This causes a tiny rise in temperature that kills the cells in the tumor. As a result, new ablation treatments can work together after surgery. Photothermal materials and photosensitizers can also produce optical signals. The creation of imaging-guided multifunctional nano-platforms for combination therapy has received increasing attention in recent years [2].

The development of optical imaging technology based on IGS has received a lot of attention, especially in the fields of nanomedicine and tumor surgery, where optical imaging technology is inseparable from our lives. However, optical imaging technology faces a number of obstacles in clinical practice, including 1) how to increase deep tissue infiltration without reducing high-intensity contrast; 2) how to increase the tumor ratio of SBR or T/NT to accurately identify the tumor; 3) whether or not they are able to last long enough for the surgeon to be satisfied that they can finish all surgical procedures; 4) how to quickly and safely remove the substance from the body. The nanoplatform-based optical imaging, on the other hand, makes us happy because it enables us to overcome the drawback of effective optical imaging methods in clinical applications and thus increases the likelihood of IGS moving from the laboratory to the clinic [4].

However, the doctor cannot alone determine the tumor boundary or the tiny residual lesions, so a complete resection is a good wish. We have to admit that using only existing technologies and equipment that cannot even remotely provide real-time surgical imaging makes it difficult to achieve a 100% complete resection. In clinical settings, molecular imaging can reveal as many surgical targets as possible; however, optical imaging contrast tumor agents cannot penetrate thick subcutaneous fat or body cavity septa. However, advances in nanotechnology and materials science have resulted in new surgical treatment options, such as surgery-based synergistic anti-cancer strategies and real-time intraoperative growth surveillance (IGS), which can offer patients a comprehensive array of accurate pre-, intra-, and post-operative tests. For surgical imaging, we can create novel contrast agents that improve tissue penetration. In addition, the nano-sized carrier, which is capable of flexibly modifying specific targeting ligands, can accumulate in large quantities at the injection site and penetrate to the edge of the tumor tissue to reveal hidden areas [5].

Conclusion

Potential solutions for precise surgery and relatively complete tumor elimination can be found when molecular imaging with high resolution, specificity, and sensitivity is combined with nanotechnology. Despite the fact that most novel nanomaterials based on IGS or synergistic surgery have failed to reach clinical translation tumor due to potential safety concerns for tissue, such as off-target effects, we should be concerned about Nano systems in actual use. However, preclinical research indicates that it has a significant therapeutic effect and significant potential. In order for tumor nanotechnology to benefit a greater number of patients, it is hoped that researchers will soon be able to overcome the challenges posed by its application in clinical settings.
