Cannabis and Cancer: What do we really know?

By Dr. Peter Brett, MD – Medical Oncologist

As an oncologist for more than a quarter century, I see several hundred patients with cancer every month. Care involves treating, counseling, supporting and listening to them. More than a third of those diagnosed with cancer will unfortunately die from it, and no one escapes its effects on health. Nearly everyone diagnosed with cancer will ask these questions: How can I make this cancer go away and stay away? How can I get relief from symptoms, such as nausea, pain, and poor appetite? What can I do to improve my sense of well-being? Now that cannabis will be legally available in the CNMI, many of my patients and their family members will want to know whether cannabis can help or hurt, and how it’s used medicinally.

Parts of the cannabis sativa plant can be turned into many products these days, and you can get them into your body in a variety of ways. Cannabis can be smoked, vaped, eaten, and “dabbed” (which involves the flash vaporization of cannabis concentrates applied to a hot surface and inhaled). The plant has more than 100 “cannabinoids,” related compounds that bind to cannabinoid receptors in the nervous system. The main two—tetrahydrocannabinol (THC) and cannabidiol (CBD)— are often put into cannabis products in different ratios. THC is the only cannabinoid that’s “psychoactive,” causing the euphoria of a marijuana high. THC is also formulated as a Food and Drug Administration (FDA) approved drug—dronabinol—which has been around for 30 years. Is cannabis an effective treatment? After a massive review of the current scientific literature published recently by the National Academies of Sciences, Engineering, and Medicine, here’s the truth as I know it, and how I respond to my patients’ questions.

1. Do cannabis products make a cancer go away and stay away? Though there are anecdotal cases of cancers receding with cannabis, there are no major, well-done studies in people that show a general benefit. It’s too bad these studies haven’t been done, and maybe they will be done some day, but in the meantime, we have many proven and effective treatments for cancer that should be considered first. Nevertheless, at some point in their treatment, some patients will opt to try cannabis products with different ratios of THC and CBD, and I think that’s okay, there’s little harm in trying.

2. Are cannabis products effective in minimizing cancer symptoms such as nausea, pain, and poor appetite? Absolutely. However, the effect is only mild to moderate. For severe nausea or pain, we have better treatments, but cannabis products often have few side effects, which can be an advantage. It’s likely that THC helps best with nausea, but both THC and CBD may help relieve pain and improve appetite.

3. Do cannabis products help improve a sense of well-being? Studies show that patients with advanced cancer can have an improved sense of well-being if they use cannabis that contains THC. However, some people don’t like the “high” feeling that THC causes. Here are two real examples, of patients who used cannabis as a medical treatment, which resulted in different outcomes. (Their social and clinical histories have been changed to maintain confidentiality.)

Case One: Patient LS is a 50-year-old woman, a tennis player, with prior sun exposure. She developed a serious skin cancer called melanoma, in the skin of her left arm, three years ago. This was surgically removed, but unfortunately the cancer spread extensively to her lungs a year later. We recommended treatment with immunotherapy (which stimulates immune cells to attack the cancer) which has been approved by the FDA, but the patient opted to try cannabis oil that contained both THC and CBD. Though LS felt a little “spacey” and “forgetful” from the oil, remarkably, the melanoma in her lungs has gradually gone away. Now, two years later, CAT scans show no sign of melanoma, and she’s probably cured. It’s possible the cancer might have spontaneously improved on its own, but cannabis certainly could have played a role.

Case Two: Patient RL is a 60-year-old man, a retired business executive, always in good health. A year ago he was losing weight and experiencing pain. Exam, blood tests, and scans showed he had prostate cancer, and it had spread to nearly all his bones. Chemotherapy and hormonal treatments helped for a time, but the cancer then quickly got worse. RL didn’t try another type of chemotherapy that we recommended, and instead took only cannabis oil with THC and CBD. Although he felt a little better for a few weeks, the cancer continued to grow rapidly, and he recently died.

Bottom Line: Though there are anecdotal cases of cancers receding with cannabis, there are no major, well-done studies in people that show a general benefit.

Hand, Foot, and Mouth Disease: Symptoms and Advice

By Dr. Elizabeth Triche, MD, MPH – CHCC Pediatrician

We have been having a lot of “Hand, foot and mouth” disease, caused by Coxsackie virus, in clinic in the past 2 weeks. It can cause high fevers and blisters or red spots in those areas, as well as cough, runny nose, and loose stools. Kids younger than two can get the rash all over their body, in addition to their hands and feet and mouth. Patients may just have the fever or the rash with no other symptoms.

If your child has this, the virus itself generally isn’t a big deal and their body should get rid of it in a week or so. There is nothing your doctor can do to speed this up (generally no clinic visit is necessary). The big thing is that the mouth lesions can be super painful, so keeping them hydrated and getting them to drink enough can be extremely challenging. IF THEY DO GET DEHYDRATED, TAKE THEM TO THE DOCTOR. Dehydration is very serious, and can be life-threatening. If they are urinating less than usual and it has been more than 6 hours since their last urine, they are already getting too dry. Later signs of dehydration are when they stop crying with tears or the soft spot on a baby’s head starts to appear sunken and they no longer have energy to wake up.

Tips for caring for a child with Coxsackie virus:

  • It’s okay if they don’t eat for a few days if they’re otherwise healthy kids, but they need to be drinking.
  • If they aren’t eating anything, they’ll need to take some drinks with salts in them (such as Gatorade, Pedialyte, or soup broth) to keep the salt levels in their blood from getting low.
  • Ibuprofen/Advil/Motrin is a much better pain reliever for this kind of inflammatory pain than Tylenol/Acetaminophen/MPAP.
  • Don’t give them any acidic foods or drinks (such as orange juice or pineapple) as this burns the open wounds in their mouth. Milk, water, popsicles, and jello are all soothing sources of hydration.
  • If your kid is having trouble drinking because of the pain, you can try “magic mouthwash” a mix of equal parts maalox, benadryl and lidocaine that can be painted on the lesions with a q-tip so they are soothed long enough to drink.
  • Please also note that they are VERY CONTAGIOUS. Be sure to wash your hands meticulously after touching their saliva or stools as they are contagious and shedding virus in these fluids

While this virus is generally self-limited and requires no medication or care from a doctor, we are always happy to see you at CHCC if you have concerns. If you believe someone’s health or life is in immediate danger, please call 911 or bring them to the CHCC Emergency Room.
