Herbal supplement usage among cancer patients

Abstract

Background: Herbal supplements (HS) are one of the most commonly used complementary and alternative medicines in cancer. Reduced therapeutic efficacy of prescription anticancer agents through unwarranted herb–drug interactions is a major efficacy/safety concern. In view of the rising cancer prevalence in India along with a high degree of reliance and cultural acceptability in favor of traditional medicine drugs, prevalence data exclusively of HS usage during cancer treatment are of considerable epidemiological significance. Methodology: This questionnaire-based prospective observational study aimed at estimating the prevalence of HS among cancer patients during treatment at our tertiary care medical center. Taken on a population of 220 patients within a period of 9 months, data were generated by a customized validated questionnaire and the same processed by IBM SPSS Statistics for Windows, version XXIV, Armonk, NY: IBM Corp. Differences between HS use and nonuse with respect to demographic, disease, and treatment characteristics were assessed by Chi-square test. For examining the latter variables as possible predictors of HS usage, they were entered into bivariate logistic regression with odds ratio and confidence intervals calculated for each. Results: Out of 220 patients, 57 (26%) were HS users and 163 (74%) were nonusers. Majority of the users (42.1%) were on self-prepared folklore herbal medicine postdiagnosis of cancer (57.9%), the most common reason cited being symptom palliation (35.1%) on the advice of friends and family (64.9%). Fear of disapproval was the most common reason cited (68.4%) for not disclosing HS usage to the physician. Conclusion: Chemotherapy and unemployment are predictors of HS usage, and there is a significant association between occupation status and HS usage. This first study on HS prevalence among South Indian population proposes the need for a more robust evidence base for understanding all aspects of HS use in cancer.

Self-Medication during and after Cancer: A French Nation-Wide Cross-Sectional Study

“…For example, in the specific context of cancer, several interactions between anticancer drugs and herbal medicines are well documented, such as enzymatic induction related to Saint John’s Wort or enzymatic inhibition related to grapefruit juice [ 36 ]. Herbal medicines are frequently used by cancer patients, ranging in prevalence from 19.7% to 69% [ 37 , 38 , 39 , 40 ], and patients taking herbal medicines have lower overall survival at 3 and 5 years than patients not taking herbal medicines [ 37 ], which underlines the unknown safety of these behaviors and self-medication practices. Moreover, self-medication practices can delay cancer diagnosis (e.g., gastrointestinal cancer [ 41 , 42 ], hematological malignancies [ 43 ]).…”

“…The prevalence of herbal drug use in cancer patients is about 50%, with variations depending on socio-demographics and country. Reasons for consuming natural compounds are manifold and include symptom palliation, boosting the immune system, and/or improving conventional treatment [ 3 , 4 ]. Nevertheless, the high popularity of herbal “natural therapy” is not always supported by knowledge of the mode of action.…”

Facebook counselling in the field of complementary and alternative medicine (CAM) among Polish breast cancer patients: a narrative review

“…Herbal products contain many natural chemicals that share metabolic pathways with some anti-cancer drugs, potentially leading to under-or over-exposure to these drugs and consequently to treatment failure or increased toxicity. Therefore, CAM-drug interactions are a significant concern when treating cancer patients [11,13,14]. The potential interactions between CAM and anticancer drugs are estimated to be around 55-85% in patients taking both types of treatment [15].…”
