    Abstract:
    BACKGROUND: Targeted therapy (TT), chemotherapy, and traditional Chinese medicine herbal treatment (TCM) can improve the prognosis of advanced pulmonary adenocarcinoma patients. Their independent prognostic value is unknown. OBJECTIVE: To study whether TCM improves survival in stage IV pulmonary adenocarcinoma patients with platinum-based chemotherapy (PBT), or combined PBT and second-line TT. METHODS: Retrospective analysis of 133 fully ambulant clinical outpatients treated with PBT alone or PBT with/without second-line TT, with/without TCM. Univariate (Kaplan-Meier) and multivariable (Cox model) survival analysis were performed, using disease-specific mortality as an endpoint. RESULTS: Gender (P = .002), TT (P < .0001), and TCM (P < .0001) had univariate prognostic value but not age, radiotherapy, or TCM syndrome differentiation (P > .10). TCM herbal treatment (P < .0001) and TT (P = .03) had multivariable independent prognostic value. TCM-treated patients (n = 103, PBT+TT+TCM+ = 62; PBT+TT-TCM+ =41) had 88% 1-year overall survival rate with median survival time (MST) of 27 months, contrasting 27% 1-year overall survival and MST of 5.0 months for non-TCM-treated (n = 30) patients. Patients with chemotherapy/TT/TCM (PBT+TT+TCM+, n = 62), TCM without TT (PBT+TT-TCM+, n = 41), or chemotherapy only (PBT+TT-TCM-, n = 30), had 1-year survival rates of 94%, 78%, and 27% respectively; for these 3 groups, respectively, MST was not reached (MST of 30.9 months), 22.6, and 5.0 months (P < .0001). CONCLUSIONS: TCM herbal treatment may improve survival of stage IV pulmonary adenocarcinoma patients treated with chemotherapy without or with second-line TT. This warrants formal phase 1 and 2 trials and ultimately properly designed prospective clinical validation trials with adequate methodology developed for data collection.
