Selected Vegetables/Sun's Soup (PDQ®): Complementary and alternative medicine - Health Professional Information [NCI] - Human / Clinical Studies
Among these 12 patients, two had no residual tumor after surgery to remove the primary tumor (n = 1) or surgery to remove the primary tumor and a contralateral lymph node metastasis (n = 1). The patient with the lymph node metastasis consumed FSV for more than 32 months and remained tumor free more than 30 months. This patient survived more than 33 months. The other patient ingested FSV for 14 months and survived 20 months. No information was available concerning the tumor-free period for this second patient.
Among the ten remaining eligible patients, two were reported to have had a complete response to therapy. One of the patients had surgery to remove the primary tumor and then chemotherapy, radiation therapy, and FSV therapy to treat pleural effusion. This patient ingested FSV for 5 months and was still alive at the end of the study period (more than 8 months later). The other patient had surgery to remove the primary tumor, and then radiation therapy and FSV therapy to treat brain and bone metastases. This patient consumed FSV for 16 months and survived 22 months. No information was available about the duration of the tumor-free period for the remaining patient.
Among the eight remaining eligible patients, three had a partial response to treatment, and four had stable or progressive disease. Tumor response data were not available for one eligible patient.
Overall, the median survival time for the 12 eligible patients was 33.5 months, which is substantially longer than the median survival times cited by the developer for historical control subjects (range, 4–15 months). Furthermore, the KPS score, which was measured at the start of FSV treatment and again 5 or more months later, improved for all but one of the eligible patients. On average, the second KPS score was 63% higher than the first score.
As in the case of the phase I/II trial, the results of this nonconsecutive case series should be viewed with caution. Once again, a number of major weaknesses in the design of this clinical study could have influenced its outcome. Among these weaknesses are the following:
- The study included only a small number of patients.
- The survival analysis relied on comparisons with historical control subjects rather than an actual control group.
- All of the patients in the study were aware of the reported benefits of Selected Vegetables/Sun's Soup and had actively sought treatment with it.
