Alternative methods for local ablation-interventional pulmonology: a narrative review.

Area of Science:

• Pulmonology
• Oncology
• Interventional Radiology

Background:

• Oligometastatic lung cancer presents unique treatment challenges compared to high tumor burden disease.
• Percutaneous ablation techniques carry risks like pneumothorax, especially for peripheral or perivascular lesions.
• Bronchoscopic ablation is emerging as a safer alternative to transthoracic procedures.

Purpose of the Study:

• To review the background and recent advancements in bronchoscopic ablative therapies for lung cancer.
• To focus on the application of these techniques for focal parenchymal lung lesions.
• To evaluate bronchoscopic ablation as a lung-sparing alternative.

Main Methods:

• A narrative literature review was conducted.
• The review summarized historical approaches, technical details, and biological rationale.
• Current evidence and future applications of various bronchoscopic modalities were assessed.

Main Results:

• Historically challenging peripheral tumor targeting has improved with advanced imaging and navigation.
• Combined imaging guidance and adapted ablative technologies enhance treatment efficacy.
• Bronchoscopic therapies offer potential for reduced complications compared to percutaneous methods.

Conclusions:

• Bronchoscopic ablative therapies are becoming realistic alternatives for lung cancer treatment.
• Further research and development will establish these as viable lung-sparing options.
• These techniques hold promise for both primary and oligometastatic lung diseases.
