With medical cannabis emerging as a novel component of supportive care, this study investigated the impact of medical cannabis use on oncological outcomes in patients with ovarian cancer undergoing PARPi therapy. Methods The study included patients from a single institution database treated for ovarian cancer between January 2014 and January 2020 who received PARPi maintenance therapy in a first-line or recurrent disease setting after a confirmed response to platinum-based treatment. The study categorized patients as cannabis users and cannabis-naïve. Univariate and...

We aimed to describe the patterns and perceptions of medical cannabis use among young adults with cancer. Methods This cross-sectional survey was conducted from March to May 2021 and included patients aged 18–45 from the Department of Oncology at Sheba Medical Center, as well as participants from the Stop-Cancer social platform. Participants completed an anonymous questionnaire assessing demographics, disease status, cannabis permit status, use patterns and perceptions. Results Of the 605 participants who completed the survey, 250 held an active cannabis permit. Median age was 38 (IQR...

Findings  In this cohort study of 116 076 individuals, people with cannabis use disorder had an increased risk of any HNC, as well as oral, oropharyngeal, nasopharyngeal, salivary gland, and laryngeal cancer, compared with a group of matched individuals. Meaning  The results of this study suggest that patients with cannabis-related disorder may be at an increased risk for HNC, and further studies are required to further explore the strength and potential mechanisms of this association. Abstract Importance  Cannabis is the most commonly used illicit substance...

This study aims to map the therapeutic benefits and adverse effects associated with the use of cannabis-based drugs in these outcomes. Methods Following Joanna Briggs Institute guidelines a scoping review was conducted. The study protocol was available in the Open Science Framework public repository. An extensive search strategy involving databases like Cochrane Library, Embase, CINAHL, Medline/PubMed, Lilacs, Google Scholar, and Open Gray for gray literature analysis was executed by a skilled librarian. The inclusion criteria were primary studies (observational...

Simple Summary Cancer is a major disease and a leading cause of death worldwide. Improving treatment and management strategies for cancer is critical. This article explores cannabis and its pharmacological properties as a promising tool in cancer care, especially in easing symptoms like appetite loss, pain, nausea, vomiting, and insomnia. Moreover, it examines the anti-tumor properties of cannabis, highlighting that, although some evidence suggests benefits, more research is necessary to confirm these effects. The article addresses the evidence concerning the clinical challenges of using cannabis, such as its psychoactive effects, and potential side effects. The article aims to clarify the current understanding of cannabis...

Abstract Medical cannabis with cancer as a qualifying condition has become legalized in more states, but currently there are no standardized measures of perceived benefits and harms of cannabis use in cancer. This study surveyed a population-based sample of cancer survivors (n = 1539) with various types of cancer including breast (25%), prostate (17%), and gastrointestinal (11%) cancers. Item response theory analyses were used to evaluate the items for measuring perceived benefits and harms. Item response theory evaluates survey items by estimating the accuracy (analogous to reliability) and severity reflected by each item. Item response theory analyses showed all the items were accurate (reliable) measures of...

Abstract Background: Breast cancer therapy has been facing remarkable changes. Classic treatments are now combined with other therapies to improve efficacy and surpass resistance. Indeed, the emergence of resistance demands the development of novel therapeutic approaches. Due to key estrogen signaling, estrogen receptor-positive (ER+) breast cancer treatment has always been focused on aromatase inhibition and ER modulation. Lately, the effects of phytocannabinoids, mainly Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD), have been evaluated in different cancers, including breast. However, Cannabis sativa contains more than 120 phytocannabinoids less researched and understood. Methods: Here, we evaluated, both in silico and in vitro, the ability of 129 phytocannabinoids to modulate important molecular...

Abstract Background Patients with cancer report increasing rates of cannabis use, often to manage symptoms and toxicities. The efficacy and safety of cannabis, however, for some use cases remains unclear. To better understand characteristics of patients with cancer who report using cannabis, we examined data from a cannabis use survey of among patients with cancer seen at a National Cancer Institute–Designated Cancer Center. Methods In late 2021, patients with cancer (N = 1608) treated between July 2017 and December 2019 provided cannabis use data. Additional data were obtained from medical records data and routine patient-reported outcomes collected for clinical purposes. Univariable analyses and multivariable regression analyses...

Abstract Cancer comes in second place on the list of causes of death worldwide. In 2018, the 5-year prevalence of breast cancer (BC), prostate cancer (PC), and colorectal cancer (CRC) were 30%, 12.3%, and 10.9%, respectively. Cannabinoids are chemicals derived from the Cannabis sativa plant; the most investigated cannabinoids are cannabinol, delta 9-tetrahydrocannabinol (Δ9-THC), and cannabidiol. In humans, the endogenous endocannabinoid system consists of endocannabinoids, cannabinoids receptors (CBs), and enzymes that degrade the endocannabinoids. In this review, we will review the most recent literature for evidence that discusses the role of cannabis in the treatment of the three types of neoplasms mentioned. Studies have proved that...

Simple Summary Symptom management is a key goal of palliative cancer care. There is growing interest in the use of cannabis-based medicines or products for the management of physical and psychosocial symptoms associated with cancer or cancer treatment, including pain, nausea and vomiting, insomnia, and mood disorders. However, research on medical uses of cannabis has been limited because of legal restrictions and stigma. The goal of this review is to explore the potential role of cannabis and cannabinoids in the management of cancer-related symptoms. Limited evidence suggests that cannabis may improve cancer-related pain, chemotherapy-induced nausea and vomiting, appetite and chemosensory changes, insomnia, and mood...
