Selected Vegetables/Sun's Soup (PDQ®): Complementary and alternative medicine - Health Professional Information [NCI] - Summary of the Evidence for Selected Vegetables / Sun's Soup
Existing data supporting the effectiveness of Selected Vegetables/Sun's Soup as a treatment for cancer are limited and weak. To date, only two clinical studies have been reported in the peer-reviewed scientific literature.[1,2] These studies tested the ability of Selected Vegetables/Sun's Soup to prolong the survival of patients with advanced non-small cell lung cancer. Although ingestion of Selected Vegetables/Sun's Soup was associated with improved survival in both studies, the results may not be reliable because of the small numbers of patients included in the studies (i.e., a total of 18 evaluable patients) and because of other major weaknesses in the designs of the studies. Different formulations of Selected Vegetables/Sun's Soup were used in the two studies, making a comparison of the results difficult. Information about the effectiveness of Selected Vegetables/Sun's Soup as a treatment for other types of cancer is found only in anecdotal reports, and no information is available about the safety or the efficacy of this treatment approach in pediatric patients. Additional larger, well-designed clinical studies that test identical formulations of vegetables and herbs are necessary to determine more clearly whether Selected Vegetables/Sun's Soup can be useful in the treatment of non-small cell lung and other types of cancer.
Separate levels of evidence scores are assigned to qualifying human studies on the basis of statistical strength of the study design and scientific strength of the treatment outcomes (i.e., endpoints) measured. The resulting two scores are then combined to produce an overall score. For additional information about levels of evidence analysis, refer to Levels of Evidence for Human Studies of Cancer Complementary and Alternative Medicine.
Purpose of This Summary
This PDQ cancer information summary for health professionals provides comprehensive, peer-reviewed, evidence-based information about the formal ranking system used by the PDQ Editorial Boards to assess evidence supporting the use of specific interventions or approaches. It is intended as a resource to inform and assist clinicians who care for cancer patients. It does not provide formal guidelines or recommendations for making health care decisions.
