Because most of the information derived from clinical trials on cannabinoids in cancer is derived from studies of those licensed pharmaceuticals, the present review discusses findings from studies of those agents as well as from studies of cannabis itself.
To date, two types of cannabinoid receptors seven-transmembrane domain G protein—coupled receptors have been identified in humans and other animal species 9. The cb1 receptor, initially identified in the brain, is found in high concentrations in areas involved in the processing of noxious stimuli. The cb2 receptor is predominantly located in cells of the immune system and likely has a role in the control of inflammation and cell proliferation. The cb receptors are not present to react with the phytocannabinoids from cannabis alone.
It has been suggested that the entire function of the system of cannabinoid receptors and endocannabinoids might be to assist in modulation of the response to pain. With that in mind, it is not surprising that an increasing body of knowledge is being developed about the effects on pain of cannabinoid medicines. A recently published systematic review 10 considered 28 studies involving a total of participants and preparations including inhaled cannabis, dronabinol, nabilone, and nabiximols, among others.
Twelve of the studies investigated neuropathic pain, and three looked at patients with cancer pain. The studies generally showed improvement in pain measures, with an overall odds ratio of 1. An earlier systematic review of eighteen randomized controlled trials of cannabinoids in participants with chronic non-cancer pain found that fifteen of the studies reported a significant analgesic effect for the cannabinoids compared with placebo, and a number of the studies also noted improvements in sleep Another review that included six of those eighteen studies in patients with cancer-related pain also favoured cannabinoids Neuropathic pain is certainly problematic in cancer patients A systematic review of six randomized, double-blind, placebo-controlled trials of cannabinoids five specifically addressing neuropathic pain found evidence for the use of low-dose medical cannabis in refractory neuropathic pain in conjunction with traditional analgesics Another analysis reviewed five trials of inhaled cannabis in patients with hiv -related peripheral neuropathy and again found a positive effect for cannabis compared with placebo A recent small study 16 showed a dose—response effect for vaporized cannabis in the relief of pain from diabetic peripheral neuropathy, a huge clinical problem estimated to affect million people worldwide.
With all of those impressive data suggesting that cannabinoids could be effective in peripheral neuropathy, where are the studies in patients with chemotherapy-induced peripheral neuropathy? Preclinical studies in rodent models have suggested that cannabinoids might actually be able to prevent peripheral neuropathy. Activation of the cb1 and cb2 receptors suppresses the development of vincristine-induced peripheral neuropathy in rats In mice receiving daily cisplatin, administration of anandamide an endocannabinoid together with an inhibitor of the fatty-acid amide hydrolase that metabolizes anandamide attenuated chemotherapy-induced peripheral neuropathy Cannabidiol pretreatment stops paclitaxel-induced neuropathy in mice To date, the only human study of a cannabis-based medicine in chemotherapy-induced peripheral neuropathy is a crossover placebo-controlled trial of nabiximols Overall, reported pain scores were not different with nabiximols and with placebo.
However, on a 0—10 scale, 5 responders reported a greater than 2-point decline in neuropathic pain. That observation suggests that 5 patients have to be treated with the sublingual preparation for 1 to experience clinical benefit an acceptable number-needed-to-treat for a neuropathic condition , suggesting that further investigation of cannabis medicines in chemotherapy-induced peripheral neuropathy is warranted. Even more exciting would be a study demonstrating the potential for cannabis to actually lower the risk for neuropathy or to prevent it from developing in the first place, as the animal models suggest.
In animal models, cannabinoids and opioids have been demonstrated to have synergistic analgesic effects Analgesic effects of cannabinoids are not blocked by opioid antagonists, suggesting that the two types of agents work through different receptors and pathways.
An early study found that thc was ineffective as an analgesic on its own, but that it slightly increased the effect of morphine on 2 of 3 measures A randomized controlled trial of nabiximols in cancer patients with poorly controlled pain despite a stable opioid regimen found that the sublingual preparation 4, 10, or 16 sprays daily for 5 weeks reduced both pain and sleep disruption A pharmacokinetic interaction study of vaporized cannabis in 21 patients with chronic—mostly non-cancer—pain taking sustained-release morphine or sustained-release oxycodone showed no significant effect on plasma levels of the opiates, but a suggestion of enhanced analgesia However, that small study was not powered for a pain endpoint, suggesting that a larger follow-on trial is warranted Clinically, I have observed that many cancer patients benefit from adding cannabis to their pain regimen.
Although the effect on chemotherapy-induced peripheral neuropathy has not been glaringly obvious, other sorts of cancer-related pain appear to respond. Patients who have been put on high doses of opiates at the end of life by their well-meaning oncologist or palliative care team frequently feel totally unable to communicate with their loved ones in their precious remaining time because of altered cognition.
Many have successfully weaned themselves down or off their opiate dose by adding cannabis to their regimen. Although it would seem that thc -dominant strains of cannabis would be most likely to have analgesic effects, patients often report significant pain reduction from strains that are predominantly cbd -rich. Although cbd does not actually bind to the cb1 receptor, it does block the fatty-acid binding protein that transports the endocannabinoid intracellularly to be hydrolyzed by the fatty-acid amide hydrolase, hence allowing the endogenous cannabinoid complexed with the receptors to persist As an oncologist practicing medicine in San Francisco since the early s, I have often said that I need a clinical trial to demonstrate that cannabis is an effective antiemetic about as much as I need a placebo-controlled trial to demonstrate that penicillin is an antibiotic!
It would appear that, if the single most active constituent of the plant is licensed and approved for treatment of chemotherapy-induced nausea, that the parent botanical should also work. Being aware that the plural of anecdote is not evidence, I would like to share an e-mail message from a year-old gentleman with metastatic colon cancer requesting a renewal of his medical cannabis authorization:.
Although I did not use it until my last 5 sessions of chemo me getting over the stigma of its use , it did what no other drug could do, completely solve the severe nausea I had. It allowed me to play with my children, attend their sports and school functions, and just function very normally in day to day activities.
I am currently on a chemo vacation after a clean scan, and the only time I use medical marijuana now is when I have trouble sleeping. I would like to continue to use it for that purpose instead of relying on pharmaceutical options like zolpidem etc. That message is representative of what many patients have recounted to me over the past plus years of oncology practice in a locale in which patients have never had difficulty accessing cannabis.
However, data from controlled clinical trials of cannabis are less impressive. Only three trials have looked at cannabis in the treatment of chemotherapy-induced nausea and vomiting, and in two of them, cannabis was made available only after dronabinol had already failed.
The first trial noted a significant benefit for cannabis compared with placebo in patients receiving high-dose methotrexate A later study by the same investigators made cannabis available to patients receiving cyclophosphamide or doxorubicin after dronabinol failure, and no beneficial effect was noted The third study investigating cannabis was a randomized crossover trial in 20 patients who received dronabinol and cannabis Overall, 5 of the patients reported a positive antiemetic response.
Of the entire cohort, 4 patients preferred smoked cannabis, 7 preferred dronabinol, and 9 had no preference. A recent phase ii investigation in 16 patients of nabiximols, the sublingually delivered whole-plant extract, found that 4. A quantitative systematic review 32 that included 30 randomized comparisons of oral nabilone, oral dronabinol, or the intramuscular levonantradol preparation no longer available with placebo in patients receiving chemotherapy found that, as antiemetics, cannabinoids were more effective than prochlorperazine, metoclopramide, chlorpromazine, thiethylperazine, haloperidol, domperidone, or alizapride risk ratio: For complete control of nausea, the number needed to treat was 6, and it was 8 for complete control of vomiting.
In crossover trials, the patients preferred cannabinoids for future chemotherapy cycles. A later systematic review 33 of thirty randomized controlled trials involving patients also found that cannabinoids were more effective than placebo or conventional antiemetics in reducing chemotherapy-induced nausea and vomiting, and that patients preferred the cannabinoids.
Adverse effects were noted to be more intense and to occur more frequently in patients using cannabinoids. A more recent systematic review 10 of twenty-eight randomized controlled trials twenty-three using nabilone or dronabinol involving participants reported an overall benefit for cannabis.
A Cochrane review 34 analyzed twenty-three randomized controlled trials of cannabinoids compared with placebo or with other antiemetic drugs. Patients were more likely to report a complete absence of nausea and vomiting with cannabis than with placebo, and there was little discernable difference between the effectiveness of cannabinoids and of prochlorperazine, metoclopramide, domperidone, and chlorpromazine.
Notably, however, none of the trials involved the agents now most widely used—the serotonin 5-HT 3 antagonists. The National Comprehensive Cancer Network guidelines cautiously mention cannabinoids as a breakthrough treatment for chemotherapy-induced nausea and vomiting not responsive to other antiemetics Although cannabis is the only antiemetic that is also orexigenic, no clinical trials investigating the plant as a treatment for cancer-related anorexia—cachexia syndrome have been conducted to date.
A randomized placebo-controlled clinical trial evaluating a cannabis extract and dronabinol in patients with cancer-related anorexia—cachexia syndrome found that neither preparation was superior to placebo with respect to affecting appetite or quality of life A large study of advanced cancer patients randomized participants to receive the progestational agent megestrol acetate or dronabinol, or both Compared with participants in the dronabinol group, those in the megestrol arm experienced a significantly greater increase in both weight and appetite, and combining dronabinol with megestrol offered no additional benefit compared with megestrol alone.
One smaller study of dronabinol in cancer patients demonstrated enhanced chemosensory perception in the treatment group compared with the placebo group In the dronabinol recipients, food tasted better, and appetite and caloric intake increased. Similarly variable and largely unimpressive results for dronabinol with respect to appetite and weight in hiv -associated wasting have also been reported Close Find information, articles and activities relevant to you.
