Split-course palliative radiotherapy for advanced non-small cell lung cancer

Area of Science:

• Oncology
• Radiation Oncology
• Palliative Care

Background:

• Palliative chest radiotherapy (RT) is crucial for managing severe symptoms in lung malignancies, such as bleeding or airway compression.
• Optimal palliative RT regimens lack consensus, necessitating research into effective treatment schemas.

Purpose of the Study:

• To evaluate the outcomes of a split-course palliative chest radiotherapy regimen.
• To assess symptom relief, toxicity, and survival impact in patients receiving this treatment.

Main Methods:

• Retrospective review of 140 patients treated between 1995 and 2006.
• Split-course RT: initial 25 Gy in 10 fractions, followed by a 2-week break, then an additional 10 Gy to 50-62.5 Gy.
• Assessment of symptom relief, toxicity, and survival using clinical notes and patient-reported outcomes.

Main Results:

• Symptomatic relief achieved in 52-84% of patients, with 58% experiencing durable palliation.
• No grade 3-5 toxicities observed; grades 1-2 esophagitis (34%) and pneumonitis (8%) were reported.
• Median survival was 5 months, with no adverse impact on survival from the treatment.

Conclusions:

• Split-course palliative RT provides significant symptomatic improvement for lung cancer patients.
• The treatment break facilitates patient selection for higher doses and balances benefits with toxicity.
• This regimen is a viable alternative for patients unable to tolerate continuous treatment.
