Could a common chemo drug boost the benefits of palliative radiation for advanced cancer?

This phase 3 trial tests whether adding the chemotherapy drug carboplatin to standard palliative radiotherapy helps control tumor growth and reduce pain better than radiotherapy alone. The study includes adults with advanced lung or head and neck cancer who need palliative radiation. Participants receive either radiotherapy plus carboplatin or radiotherapy plus a placebo, and researchers track how long the treated tumors stay under control, pain levels, and quality of life.
