Summary
This summary is machine-generated.Individuals with opioid use-related disorders face higher cancer incidence and mortality risks. Survival rates are notably lower for specific cancers like liver, pancreas, and colon cancer in this population.
Area Of Science
- Oncology
- Public Health
- Epidemiology
Background
- Limited research exists on cancer incidence and mortality among individuals with opioid use-related disorders.
- Opioid use disorder is a growing public health concern with potential long-term health implications.
Purpose Of The Study
- To investigate cancer-specific incidence, mortality, and survival rates in individuals diagnosed with opioid use-related disorders in Norway.
- To compare cancer risks and outcomes in this cohort against the general Norwegian population.
Main Methods
- A cohort study was conducted in Norway from 2010 to 2018.
- Data linkage of national health and population registers was used, including specialized healthcare records, the Cancer Registry of Norway, and the Cause of Death Registry.
- Cancer incidence and mortality were compared using standardized incidence (SIR) and mortality (SMR) ratios, with one-year survival rates computed.
Main Results
- Individuals with opioid use-related disorders exhibited increased overall cancer incidence (SIR=1.2) and more than double the cancer mortality rate (SMR=2.3) compared to the general population.
- Significant excess risks were observed for liver, larynx, lung, and pancreas cancers, while reduced risks were noted for melanoma, breast, and prostate cancers.
- One-year survival rates after cancer diagnosis were notably lower (10-15% less than general population) for liver, pancreas, and colon cancers.
Conclusions
- Cancer incidence and cancer-related mortality are elevated among individuals with opioid use-related disorders in Norway.
- These findings highlight a critical need for targeted cancer screening and prevention strategies for this vulnerable population.
- Further research is warranted to understand the underlying mechanisms and to develop effective interventions.

Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...
Opioids are a class of drugs that mimic endogenous opioid peptides and act on opioid receptors, and help in pain relief. These compounds are classified as natural, synthetic, or semi-synthetic. Natural opioids, like morphine, codeine, and thebaine, are derived from the opium poppy plant (Papaver somniferum or Papaver album) and are termed opiates. Synthetic opioids are artificial, while semi-synthetic opioids combine natural and synthetic compounds. Morphine, a prototypical opioid, possesses a...
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2,...
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...
