Cisplatin belongs to a class of medications called alkylating agents. It stops cells from replicating and dividing by interfering with their nucleic acid function. This kills cells and inhibits the growth of malignant tumours. Cisplatin is therefore used to treat multiple types of cancers, for example, metastatic ovarian or testicular cancer (a tumour that has spread to other parts of the body) and advanced (late-stage) bladder cancer. It may be used alone or together with other anticancer medications, such as Fluorouracil, to kill cancer cells.
Cisplatin is injected into a vein via a drip as directed by your doctor. This process requires many hours, and you will need to rest in the hospital ward or clinic when you are on the medicine drip. Before you start using Cisplatin, you may be given fluid drips to make you pass more urine. This may continue for another day after the treatment. You may also be given other medicines beforehand to prevent or lessen the side effects of Cisplatin. The dosage of Cisplatin is calculated by your doctor based on your total body surface area. Your doctor will advise you on the dosage and frequency depending on your condition.
Metastatic ovarian cancer
As monotherapy: 100 mg per m2 body surface area per cycle as a single dose, given once every 4 weeks.
For combination therapy with Cyclophosphamide: 75-100 mg per m2 body surface area on day 1 of every 4-week cycle.
Metastatic testicular tumours
20 mg per m2 body surface area daily for 5 days per cycle.
Advanced bladder cancer
50-70 mg per m2 body surface area per cycle once every 3-4 weeks, depending on prior cancer treatment. A lower initial dose may be used in heavily pre-treated patients.
