Abstract:

Objective

To analyze the short-term clinical efficacy and safety of 630 nm laser combined with hematoporphyrin derivatives in the treatment of advanced bronchial lung cancer.

Methods

A total of 43 patients with pathologically diagnosed bronchial lung cancer who underwent interventional tumor reduction combined with treatment with 630 nm laser and hematoporphyrin derivatives, chemotherapy, and immunotherapy were selected at the Affiliated Hospital of Qingdao University from March 2019 to September 2023. The basic clinical features and adverse reactions after treatment were recorded, and chest CT and bronchoscopy were reviewed 1 month after treatment.

Results

Chest CT showed that the tumor volume in the trachea or bronchus was significantly reduced after treatment, and ventilation was improved. Bronchoscopy showed that the tumor volume decreased or even disappeared after treatment. After 1 month of treatment, 31 patients (72.09%) were re-examined by chest CT and bronchoscopy, and the total effective rate was 70.97%. None of the 43 patients had serious complications, but 3 patients had common complications.

Conclusion

630 nm laser combined with hematoporphyrin derivatives has obvious clinical efficacy in the treatment of advanced bronchial lung cancer, and it can improve airway stenosis and relieve dyspnea, cough, and other symptoms with a favorable safety profile.
