Cancer Therapies

9.8K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

665
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
Two synthetic agonists of THC,...

Opioid Analgesics: Synthetic and Semisynthetic Opioids

906
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...

Opioid Analgesics: Morphine and Other Natural Cogeners

841
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...

Treatment Resistant Cancers

3.7K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Drugs Affecting GI Tract Motility: Opioids as Antidiarrheal Agents

607
Diarrhea, a condition marked by frequent loose or watery bowel movements, can be triggered by multiple factors such as viral or bacterial infections, food intolerances, anxiety, medications, and digestive disorders. Symptoms may include abdominal pain, bloating, nausea, and cramping. Severe or prolonged diarrhea can lead to complications like electrolyte imbalances, malnutrition, and dehydration if left untreated.
Opioids, widely used antidiarrheal agents, mitigate diarrhea by slowing down...

Summary

Hypofractionation radiotherapy for laryngeal cancer increases pain and opioid use compared to standard treatment. Corticosteroids may help manage weight loss during hypofractionation.

Area of Science:

  • Oncology
  • Radiation Oncology
  • Laryngeal Cancer Treatment

Background:

  • Hypofractionation radiotherapy shortens treatment duration for laryngeal cancer, potentially reducing accelerated tumor repopulation.
  • While improving survival, radiotherapy for laryngeal squamous cell carcinoma (SCC) can cause toxic effects like dysphagia, mucositis, and pain.
  • Standard fractionation involves 2 Gy per fraction to a total of 70 Gy for advanced disease, while hypofractionation uses 2.25 Gy per fraction to 63 Gy for early glottic cancer.

Purpose of the Study:

  • To compare early toxicity and opioid consumption between hypofractionation and standard fractionated radiotherapy for laryngeal cancer.
  • To assess the impact of hypofractionation on pain and swallowing discomfort in laryngeal SCC patients.
  • To evaluate the role of corticosteroids in mitigating treatment-related toxicities.

Main Methods:

  • Retrospective analysis of 127 laryngeal SCC patients.
  • Comparison of hypofractionation (n=64) versus standard fractionation (n=63) radiotherapy regimens.
  • Data collection on opioid usage, pain levels, weight changes, and overall toxicity.

Main Results:

  • Hypofractionation group required significantly higher opioid dosages due to increased pain and swallowing difficulties (P < 0.05).
  • Dexamethasone boluses in the hypofractionation group led to significantly less weight loss, with some patients gaining weight (P < 0.005).
  • Chemoradiotherapy for advanced-stage cancer resulted in greater toxicity compared to radiotherapy alone.

Conclusions:

  • Hypofractionation for laryngeal cancer necessitates higher opioid doses than standard fractionation.
  • Effective pain management strategies are crucial for patients undergoing hypofractionation.
  • Incorporating corticosteroids into hypofractionation protocols may alleviate weight loss and other toxicities.
