What Are the Pros and Cons of Photodynamic Therapy for Cancer?

Tumor photodynamic therapy is a new tumor treatment technology that began to form in the late 1970s. It has been officially approved by the relevant national government departments in many countries such as the United States, Britain, France, Germany, and Japan. A conventional method. The full English name of Photodynamic Therapy is Photodynamic Therapy, or PDT for short. This short name has been recognized and widely used in the international academic community.

Effect

Repeatable treatment

Compared with conventional treatment methods such as surgery, chemotherapy, and radiotherapy, photodynamic therapy has the following important advantages:

Minimal trauma With the help of fiber optics, endoscopes, and other interventional techniques, the laser can be guided deep into the body for treatment, avoiding the trauma and pain caused by open chest and laparotomy.

Photodynamic drugs that have low toxicity and enter the tissues only reach a certain level

Repeatable treatment of cancer cells has no resistance to light-sensitive drugs, and patients will not increase toxicity due to multiple photodynamic treatments, so the treatment can be repeated.

Can be palliative for advanced cancer patients, or tumor patients who cannot accept surgery due to advanced age, cardiopulmonary liver and kidney dysfunction, and hemophilia. Photodynamic therapy is a palliative method that can effectively reduce pain, improve quality of life, and extend life treatment approach.

It can be used in conjunction with surgery to improve the efficacy. For some tumors, first surgical removal and then photodynamic therapy can further eliminate residual cancer cells, reduce the chance of recurrence, and improve the thoroughness of surgery. For other tumors, it is possible to do photodynamic therapy first To reduce the size of the tumor before resection, expand the indications for surgery, and improve the success rate of surgery.

It can eliminate some clinical tumors such as transitional cell carcinoma of the bladder. There may be scattered small cancer nests that are not visible to the naked eye outside the main lesion. Conventional treatment can only remove the main lesion. It is powerless for hidden cancer nests, but With photodynamic therapy, the method of surface irradiation after full bladder filling is used to eliminate all possible small lesions, thereby greatly reducing the chance of tumor recurrence.

Protects appearance and important organ functions For facial skin cancer, oral cancer, penile cancer, cervical cancer, retinoblastoma, etc., the application of photodynamic therapy is likely to reduce the incidence of organs as much as possible while effectively killing cancerous tissues. The damage to the epithelial structure and collagen scaffold makes the appearance of wounds less affected and keeps the organs intact and normal physiological functions.
