Key Takeaway
Note that adding traditional Chinese medicine to chemotherapy may improve progression-free survival in advanced NSCLC.

This systematic review and meta-analysis of individual patient data evaluated the impact of adding traditional Chinese medicine (TCM) to chemotherapy for patients with advanced non-small cell lung cancer. The analysis synthesized results from both randomized controlled trials and observational studies.

Key findings indicate that chemotherapy plus TCM significantly improved progression-free survival (PFS), with an HR of 0.85 and a restricted mean survival time difference of 1.582 months (95% CI 0.77 to 0.93, P < 0.001). In the fixed-regimen TCM subgroup, PFS also showed significant improvement (HR = 0.85; 95% CI 0.77 to 0.94, P < 0.05). However, for the personalized TCM subgroup, the PFS benefit was not statistically significant (HR = 0.85; 95% CI 0.67 to 1.07, P = 0.17).

Regarding overall survival (OS), chemotherapy plus TCM showed significantly better outcomes compared to chemotherapy alone, though this benefit diminished over time with a restricted mean survival time difference of 4.149 months. The authors noted that the proportional hazards assumption was violated for overall survival. Clinical application is limited by the inclusion of observational data and the diminishing OS benefit over time.

How this fits prior evidence

This finding addresses a gap in managing advanced non-small cell lung cancer by evaluating traditional Chinese medicine as an adjunct to chemotherapy. While other reviewed treatments like ivonescimab plus chemotherapy or sacituzumab tirumotecan combinations show significant progression-free survival benefits, this meta-analysis specifically explores the role of TCM. The finding that chemotherapy plus TCM improves progression-free survival (HR = 0.85) provides an additional evidence point for combination strategies in advanced NSCLC.

A review of patient data suggests that combining chemotherapy with traditional Chinese medicine (TCM) can lead to better outcomes for people with advanced non-small cell lung cancer. The study looked at how these treatments affected overall survival and the amount of time patients lived without their cancer progressing.

The results showed that patients receiving both therapies had significantly better progression-free survival compared to those receiving chemotherapy alone. However, while the combination therapy improved overall survival initially, this specific benefit was found to diminish over time. The study also noted that the benefits were most consistent in groups following a fixed TCM regimen rather than personalized plans.

Because this research includes both randomized trials and observational studies, it shows an association rather than a direct cause. Additionally, some statistical limitations were noted regarding how survival was measured over long periods. Patients should talk to their doctors to see if these combined therapies are appropriate for their specific treatment plan.

What this means for you:
Combining traditional Chinese medicine with chemotherapy may improve survival outcomes in advanced lung cancer patients.

Common questions

Does adding traditional Chinese medicine help lung cancer patients live longer?

The study found that combining chemotherapy with traditional Chinese medicine was associated with better overall survival. However, the researchers noted that this specific benefit for overall survival tends to diminish over time.

How does it affect how long the cancer stays from progressing?

Patients receiving both chemotherapy and traditional Chinese medicine showed significantly improved progression-free survival. This was observed in both general groups and those following a fixed-regimen of traditional Chinese medicine.

Is this treatment safe for everyone with advanced lung cancer?

The study did not report specific side effects or safety data. Because the results are based on a mix of trial types and show an association rather than a direct cause, you should consult your doctor to discuss if this combination is right for you.

IntroductionTo evaluate the 3-year efficacy of combining traditional Chinese medicine with chemotherapy in the treatment of advanced non-small cell lung cancer, taking into account time-dependent survival effects.MethodsA systematic review and meta-analysis was conducted following PRISMA guidelines, including randomized controlled trials and observational studies that compared chemotherapy plus traditional Chinese medicine with chemotherapy alone. Individual patient data were reconstructed from Kaplan–Meier curves. For the primary endpoints of overall survival and progression-free survival, one-stage analyses employed frailty Cox models when the proportional hazards assumption held; otherwise, Royston-Parmar models incorporating time-varying effects were used. Restricted mean survival time over 0–36 months was estimated, and a two-stage random-effects model was applied for sensitivity analysis.ResultsEighteen studies (12 RCTs and 6 cohort studies) were included, with individual patient data reconstructed from 15 overall survival and 7 progression-free survival curves. The proportional hazards assumption was violated for overall survival; time-varying modeling revealed significantly better overall survival with chemotherapy plus traditional Chinese medicine therapy, with a 3-year restricted mean survival time difference of 4.149 months. In the personalized treatment subgroup, CT + TCM showed a pronounced early survival benefit, a similar benefit was observed in the fixed-regimen subgroup. For progression-free survival, combination therapy significantly improved it (HR = 0.85, 95% CI 0.77–0.93, P < 0.001), corresponding to a restricted mean survival time difference of 1.582 months. In the fixed-regimen subgroup, CT + TCM significantly improved PFS (HR = 0.85, 95% CI 0.77–0.94, P < 0.05), while in the personalized TCM subgroup the PFS benefit was not statistically significant (HR = 0.85, 95% CI 0.67–1.07, P = 0.17).ConclusionThe addition of traditional Chinese medicine to chemotherapy is associated with improved overall and progression-free survival in advanced non-small cell lung cancer, although the overall survival benefit diminishes over time.Systematic Review Registrationhttps://www.crd.york.ac.uk/prospero/ Identifier CRD420261280359.
