    Area of Science:

    • Pulmonology
    • Oncology
    • Interventional Pulmonology

    Background:

    • Endobronchial tumors pose treatment challenges, especially for patients unsuitable for conventional therapies.
    • Bronchoscopic cryotherapy presents an alternative therapeutic modality for localized airway malignancies.

    Purpose of the Study:

    • To evaluate the efficacy and safety of bronchoscopic cryotherapy for localized endobronchial tumors.
    • To assess outcomes including local tumor control, bleeding reduction, and airway patency.

    Main Methods:

    • Twenty-eight patients with localized endobronchial tumors underwent 60 treatment sessions.
    • A closed liquid nitrogen system with a specialized probe was utilized via an open ventilating bronchoscope.

    Main Results:

    Related Experiment Videos

    • Fifty-four percent (15/28) of patients experienced clinical improvement, evidenced by tumor control, reduced bleeding, or enhanced airway patency.
    • A low rate of fatal complications (3%, 2/60 treatments) was observed.
    • Complete long-term tumor control was achieved in two patients with squamous cell carcinoma.

    Conclusions:

    • Bronchoscopic cryotherapy is an effective and relatively safe treatment option for selected patients with localized endobronchial tumors.
    • The procedure can lead to significant improvements in patient condition and durable cancer control.
