Original Abstract of the Article

Major Research Findings

Cisplatin is an effective chemotherapeutic agent used to treat a wide range of cancers, but it has been reported to cause a number of serious side effects, such as nephrotoxicity, neurotoxicity, hearing loss, muscle wasting, nausea and vomiting, and liver damage. 26 , 18 , 7 , 12 , 5 , 16 , 19 , 9 , 15 , 21 , 20 , 2 These studies suggest that these side effects are caused by increased levels of reactive oxygen species (ROS) in the body and the promotion of cell death (apoptosis). 26 , 18 , 7 , 12 , 5 , 16 , 19 , 9 , 15 , 21 , 20 , 2 .

Reasons for side effects

Cisplatin's side effects are thought to be caused by the following reasons.

  • Increased levels of reactive oxygen species (ROS): Cisplatin, when introduced into the body, generates reactive oxygen species (ROS). ROS can damage cell membranes and DNA, promoting cell death (apoptosis).
  • Promotion of cell death (apoptosis): Cisplatin promotes cell death (apoptosis). Apoptosis is a programmed cell death that plays an important role in the normal death of cells. However, if apoptosis is excessively induced by cisplatin, it can lead to organ dysfunction.
  • Promotion of inflammation: Cisplatin promotes inflammation as a result of cell death. While inflammation is a natural defense mechanism of the body, excessive inflammation can lead to tissue damage and dysfunction.

Common Side Effects

Nephrotoxicity

The most common side effect of cisplatin is nephrotoxicity. 26 , 18 , 7 , 12 , 15 , 21 , 20 , 9 , 19 , 2 Cisplatin damages kidney cells, impairing kidney function. Nephrotoxicity can manifest as elevated blood urea nitrogen (BUN) and creatinine levels, reduced urine output, and edema. In severe cases, dialysis may be required.

Nausea and Vomiting

Cisplatin often causes nausea and vomiting. 23 , 27 , 13 , 25 , 8 Cisplatin affects the nerves in the digestive system, causing nausea and vomiting. Nausea and vomiting can occur immediately after cisplatin administration, but can also occur several days later. Nausea and vomiting can significantly reduce quality of life.

Neurotoxicity

Cisplatin has been reported to exhibit neurotoxicity. 7 , 5 , 11 Cisplatin damages peripheral nerves, causing symptoms such as numbness and pain. Neurotoxicity often appears in the palms and soles of the feet, but can also occur in other areas. Neurotoxicity can occur immediately after cisplatin administration or months later.

Hearing Loss

Cisplatin has been reported to cause hearing loss. 18 Cisplatin damages cells in the inner ear, causing symptoms such as hearing loss and tinnitus. Hearing loss can occur immediately after cisplatin administration or months later.

Liver Toxicity

Cisplatin has been reported to exhibit liver toxicity. 16 , 3 Cisplatin damages liver cells, impairing liver function. Liver toxicity can manifest as symptoms such as jaundice and abdominal pain.

Other Side Effects

In addition to the above side effects, cisplatin can also cause the following.

  • Hair loss
  • Anemia
  • Gastrointestinal disorders
  • Allergic reactions
  • Myelosuppression
  • Lung toxicity
  • Cardiotoxicity

Countermeasures for Side Effects

Nephrotoxicity

To prevent nephrotoxicity, it is important to stay adequately hydrated before cisplatin administration. 22 During cisplatin administration, kidney function should be monitored regularly, and dosage should be adjusted or administration should be discontinued as necessary.

Nausea and Vomiting

Nausea and vomiting can be prevented by administering antiemetics. 23 , 13 , 25 Antiemetics include drugs such as ondansetron and metoclopramide. Nausea and vomiting can also be alleviated through methods such as dietary and exercise therapy.

Neurotoxicity

To prevent neurotoxicity, taking vitamin B complex before cisplatin administration is recommended. 11 If symptoms of neurotoxicity appear, appropriate drug therapy and rehabilitation are needed.

Hearing Loss

To prevent hearing loss, administering steroids before cisplatin administration is recommended. 18 If symptoms of hearing loss appear, appropriate treatment such as hearing aids and cochlear implants is needed.

Liver Toxicity

To prevent liver toxicity, liver function should be tested before cisplatin administration, and dosage should be adjusted or administration should be discontinued as necessary. 16 If symptoms of liver toxicity appear, appropriate drug therapy is needed.

Comparison Between Studies

Commonalities Between Studies

These studies have in common the indication that cisplatin administration can cause side effects such as nephrotoxicity, neurotoxicity, nausea and vomiting, hearing loss, and liver toxicity.

Differences Between Studies

These studies show that the severity, frequency, and mechanism of side effects caused by cisplatin administration vary depending on the study. This is thought to be due to differences in the study animals, dosages, and administration methods.

Important Notes on Application to Daily Life

Cisplatin is an effective drug for the treatment of cancer, but it also carries the risk of side effects. When taking cisplatin, be sure to consult with a doctor and understand the risks and benefits of the drug before taking it. It is also important to have regular checkups and follow your doctor's instructions while taking cisplatin.

Limitations of Current Research

These studies have not yet fully elucidated the mechanisms and preventive measures for the side effects caused by cisplatin administration. Therefore, further research is needed.

Future Directions for Research

New treatments and preventive measures are needed to reduce the side effects of cisplatin administration. In particular, it is important to thoroughly elucidate the mechanisms underlying the side effects.

Conclusion

Cisplatin is an effective drug for treating cancer, but it can cause side effects such as nephrotoxicity, neurotoxicity, and nausea and vomiting. It is important to understand the risks and benefits of cisplatin before taking it. You should also follow your doctor's instructions and have regular checkups while taking cisplatin. These studies provide important information to help you understand cisplatin-related side effects and ensure safe treatment.
