What This Study Found

CBD induced apoptosis through PPAR-gamma activation, mitochondrial dysfunction, and oxidative stress. It inhibited epithelial-to-mesenchymal transition (a driver of metastasis) and enhanced CD8+ T cell and NK cell activity. CBD showed synergy with cisplatin and radiotherapy.

Key Numbers

19 studies included. CBD concentrations: 1-10 uM in cell studies, 200-600 mg/day in human cases. 13 in vitro, 4 animal, 2 clinical reports. CBD enhanced CD8+ T cell and NK cell activity in the tumor microenvironment.

How They Did This

Systematic review following PRISMA guidelines, searching PubMed, Scopus, Web of Science, and Google Scholar for studies from 2007-2025. Included 13 in vitro, 4 in vivo, and 2 clinical reports on CBD in lung cancer.

Why This Research Matters

Lung cancer remains the leading cause of cancer death worldwide. CBD's ability to enhance existing therapies while potentially reducing treatment resistance addresses two major challenges in lung cancer treatment.

The Bigger Picture

Cancer immunotherapy has transformed lung cancer treatment but many patients still do not respond. CBD's immune-modulating effects alongside conventional therapy sensitization suggest potential as an adjunct worth testing.

What This Study Doesn't Tell Us

Primarily preclinical data. Only 2 clinical reports, not controlled trials. CBD doses used in cell studies may not translate to achievable human concentrations. Risk of publication bias in preclinical cancer research.

Questions This Raises

  • ?Would CBD improve outcomes in lung cancer immunotherapy combinations?
  • ?What dose and route of administration would be needed for clinical benefit?

Frequently Asked Questions

Could CBD help treat lung cancer?

Preclinical studies show CBD can kill lung cancer cells, prevent spread, and enhance chemotherapy and radiation. However, only 2 clinical case reports exist, and no controlled trials have been completed.

Does CBD enhance chemotherapy for lung cancer?

In laboratory studies, CBD increased the effectiveness of cisplatin by improving drug uptake and helping overcome treatment resistance. Clinical trials are needed to confirm this in patients.
