Chinese researchers evaluated the effect of Chinese medicine (CM) on survival time and quality of life (QoL) in patients with small-cell lung cancer (SCLC). They conducted an exploratory and prospective clinical observation. Patients diagnosed with SCLC receiving CM treatment as an add-on to conventional cancer therapies were included and followed up every 3 months. The primary outcome was overall survival (OS), and the secondary outcomes were progression-free survival (PFS) and QoL.
A total of 136 patients including 65 limited-stage SCLC (LS-SCLC) patients and 71 extensive-stage SCLC (ES-SCLC) patients were analyzed. The median OS of ES-SCLC patients was 17.27 months, and the median OS of LS-SCLC was 40.07 months. The survival time was 16.27 months for SCLC patients with brain metastasis, 9.83 months for liver metastasis, 13.43 months for bone metastasis, and 18.13 months for lung metastasis. Advanced age, pleural fluid, liver, and brain metastasis were risk factors, while longer CM treatment duration was a protective factor. QoL assessment indicated that after 6 months of CM treatment, scores increased in function domains and decreased in symptom domains.
The authors concluded that CM treatment might help prolong OS of SCLC patients. Moreover, CM treatment brought the trend of symptom amelioration and QoL improvement. These results provide preliminary evidence for applying CM in SCLC multi-disciplinary treatment.
Sorry, but these results provide NO evidence for applying CM in SCLC multi-disciplinary treatment! Even if the findings were a bit better than those reported for SCLC in the literature – and I am not sure they are – it is simply not possible to say with any degree of certainty what effect the CM had. For that, we would obviously need a proper control group.
The study was supported by the National Natural Science Foundation of China (No. 81673797), and Beijing Municipal Natural Science Foundation (No. 7182142). In my view, this paper is an example for showing how the relentless promotion of dubious Traditional Chinese Medicine by Chinese officials might cost lives.
I feel that it is time to do something about it.
But what precisely?
Any ideas anyone?
