Some common questions for oncology pharmacists are about concurrent use of complementary and alternative medicine supplements and natural products.

Some of the most common questions oncology pharmacists address with patients who are receiving cancer therapies relate to their concurrent use of complementary and alternative medicine (CAM) supplements and natural products. Although herbal remedies, vitamins, and antioxidants are among the most popular options, patients are increasingly turning to cannabis, probiotics, and psilocybin for their potential anticancer effects as well as to alleviate treatment-associated adverse effects (AEs).

Recently, a patient on oral targeted therapy at my practice shared the treatment plan her naturopathic oncologist had prescribed, which included a couple of the products we had specifically recommended she avoid, at least as we initiated the targeted agent. Our advice was based on the potential for overlapping AEs and drug-drug interactions that might impede our ability to optimize her anticancer treatment. There were no absolutes, as there rarely are, and we continue to work with this patient as we do with others who pursue concurrent treatments. Yet I wonder if and how we might better meet patients’ needs in this area.

Pharmacy Times: Call for Papers

Pharmacy Times Oncology EditionTM and Pharmacy Times Health-System EditionTM are seeking to expand our current coverage offerings to include peer reviewed research on clinical topics and treatment of different disease states.

The publications are seeking to focus on a wide range of therapeutic categories in the oncology and health-system pharmacy space to educate readers and translate innovative clinical discoveries into improved health outcomes for patients. This new focus on clinical research seeks to accelerate adaptation of new therapeutics, techniques, and technologies from the publication’s pages to the clinical setting.

The clinical manuscripts sought will examine different treatments for and management of the different disease states and pharmacologic interventions. Of particular interest are papers that highlight the role of the pharmacist within the overall health care team and provide insight into the impact pharmacists have on patient outcomes. These submissions will be peer-reviewed and published in upcoming editions of Pharmacy Times Oncology Edition and Pharmacy Times Health-System Edition.

Some clinical topics of interest include:

  • Transitions of Care
  • Immuno-oncology
  • Hematology
  • Breast Cancer
  • Lung Cancer
  • Leukemia/Lymphoma
  • Ovarian Cancer
  • Melanoma
  • Head and Neck Cancer
  • Antimicrobial Stewardship
  • Cardiovascular Disease
  • Renal Disease
  • Metabolic Disease
  • 340B
  • Biosimilar Adoption
  • Immunizations
  • HIV and Pre-exposure Prophylaxis

To send in research paper submissions or if you have any questions, please email Davy James (djames@pharmacytimes.com) or Alana Hippensteele (ahippensteele@mjhlifesciences.com).

For several decades, survey findings have indicated that 30% to 60% of patients with cancer—and even 80% in some reports—choose supplements and nontraditional therapies in conjunction with conventional cancer treatment, and about half of them don’t inform their oncologists because of fear that they would be discouraged or that the oncologist lacks the knowledge to offer accurate advice. Most often, patients take complementary therapies with conventional treatments to manage treatment- or cancerrelated AEs but sometimes to augment treatment efficacy. The patient mentioned had been advised by her naturopathic oncologist that the recommended supplement inhibited the same signaling pathway targeted by the cancer treatment. Although acupuncture, massage, meditation, tai chi, yoga, prayer, spiritual practices, biofeedback, and art and music therapy have been studied and can help patients feel better during treatment, alternative therapies that are promoted as treatments or cures in lieu of conventional modalities are a different story.

According to the American Society of Clinical Oncology National Cancer Opinion Survey published in 2018, 40% of Americans believe that cancer can be cured solely with alternative remedies. In 2020, the same survey found that 35% of respondents agreed with that statement and 73% of Americans thought that alternative therapies are a good supplement to standard cancer treatments. Many of these therapies have been studied and remain unproven, but published evidence shows higher mortality rates for individuals who use them instead of conventional treatment.

Clearly, many of our patients are seeking more than we’re providing. The importance of complementary therapeutic approaches cannot be overstated, and the increasing number of centers that incorporate integrative oncology within their cancer prog rams reflects increased interest in this area. Oncology care providers, and particularly oncology pharmacists, are very familiar with potential drug-drug interplay between anticancer agents and supplements, be they prescribed or selfadministered, and would therefore benefit from having discussions with patients on these interactions as a part of cancer care and treatment.

In addition, concomitant use of antioxidants, vitamins, and supplements with anticancer treatments is paradoxical, given that their protective effects often target the same reactive oxygen species generated by cancer drugs and radiotherapy as mediators of anticancer activity. Most of the research to date, however, does not suggest detrimental anticancer effects, and some patients report a reduction in AEs.

Because patients choose complementary therapies for a variety of reasons, our support promotes patient autonomy and helps them cope with treatment and achieve better quality of life. To this end, proactive discussions about CAM supplements and natural products when reviewing medication histories and sensitivities may be helpful. Furthermore, eliciting information about why a patient is taking a specific supplement may help us understand trends at our centers and topics being discussed in patient forums and social media.

Although it can be quite challenging to navigate through the dozens of dietary supplements and herbal remedies some patients take, if we think about these conversations as opportunities, we can all become more knowledgeable about caring for patients today and in the future.
