Cimetidine and gastric cancer
Lancet (London, England)
|May 12, 1979
Summary
Three patients on cimetidine for dyspeptic symptoms developed gastric carcinoma. The study questions if the drug masked cancer or if the association is coincidental, stressing the need for ongoing patient monitoring.
Area of Science:
- Gastroenterology
- Oncology
- Pharmacology
Background:
- Dyspeptic symptoms are common and often treated with H2-receptor antagonists like cimetidine.
- Gastric carcinoma is a significant malignancy requiring early detection.
- The potential influence of long-term medication on cancer development warrants investigation.
Purpose of the Study:
- To report three cases of gastric carcinoma in patients treated with cimetidine.
- To explore the potential association between cimetidine use and the development or masking of gastric cancer.
- To emphasize the importance of vigilant monitoring in patients receiving long-term H2-receptor blockade.
Main Methods:
- Case series reporting clinical observations.
- Review of patient histories and diagnostic evaluations.
- Endoscopic and histopathological assessment of gastric lesions.
Main Results:
- Three patients receiving cimetidine for dyspepsia were diagnosed with gastric carcinoma.
- The causal relationship between cimetidine and gastric cancer in these cases remains undetermined.
- Possible explanations include coincidence, drug-induced masking of symptoms, or other unelucidated mechanisms.
Conclusions:
- Long-term use of cimetidine in patients with dyspeptic symptoms may be associated with delayed diagnosis of gastric carcinoma.
- Regular clinical and endoscopic surveillance is crucial for patients on prolonged cimetidine therapy.
- Further research is needed to clarify the relationship between H2-receptor blockers and gastric neoplasia.

01:15Drugs that Stabilize Microtubules
Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...
02:34Inhibition of Cdk Activity
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...
02:38Mitogens and the Cell Cycle
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
01:10Drugs that Destabilize Microtubules
Microtubules are dynamic structures and can be regulated by microtubule targeting agents (MTAs). Microtubule destabilizing drugs are a class of MTAs that destabilize and prevent microtubules' polymerization. Both natural and synthetic chemicals can be found under this class of drugs. Vincristine and vinblastine, two vinca alkaloids, and colchicine were among the first to be discovered. These drugs can affect cells in various ways, either by inducing a change in cell morphology, preventing...
01:28Acid Suppressive Drugs for Peptic Ulcer Disease: Histamine H2-Receptor Antagonists
Histamine H2 receptors, which are intricately located on the basolateral membrane of parietal cells, play a crucial role in modulating gastric acid secretion. When released from enterochromaffin-like cells, histamine engages H2 receptors, initiating the cyclic AMP (cAMP) pathway. In this pathway, adenylyl cyclase converts ATP into cAMP, elevating intracellular cAMP levels. The activation of protein kinase A follows, stimulating the proton pump. This stimulation prompts the secretion of hydrogen...
01:26Gastritis II: Pathophysiology
The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...
