What is the first line chemotherapy?
In general, chemotherapy concerns drugs that have an anti -cancer effect. There are a number of different chemotherapeutic drugs, but each falls into specific categories of use. The first -line chemotherapeutic drugs are the treatments that are likely to be the most effective, and these are medicines that the doctor usually gives first. If the first line does not work, the patient may turn into a second line medicine. Of these drugs, some benefits have more people than other drugs. Usually, when the patient finds that he has cancer, the doctor recommends treatment that contains first -line chemotherapy. The first choice drug may vary from cancer to cancer.
The chances of first -line chemotherapy that have a beneficial effect are generally higher than alternative drugs, and therefore this medicine is the first choice. Other names for the first -line medicinal regime are standard therapy, primary therapy and induction treatment. Sometimes the patient receives treatment that focuses on reducing the tumor, unlike the eradication of the tumor, and this can also be called PR therapythe line.
If the treatment of first -line chemotherapy is effective in reducing the tumor, the patient may also receive additional treatment, such as multiple drugs, radiation therapy or hormones. If initial chemotherapy does not work as the patient and physician hoped, the patient may start taking what is called the second line chemotherapy. This type of treatment also uses medicines that are toxic to cancer cells, but these drugs have slightly different properties than initial chemotherapy.
Usually it has been shown that the second line drugs have beneficial effects on cancer, which specifically not responding to the first choice. Cancer cells tend to become resistant to drugs over time, as new cells are constantly growing, which may have slightly different properties that may cause the drug to be unlimited in some cells. If there is a resistance with the first medicine, then the second medicine that may have different mechanisms of killing BUnhot to the first medicine, has a better chance of effective.
doctors may switch chemotherapy regulations if drugs do not have any beneficial effect and the patient may also be able to choose other forms of treatment such as surgery or radiation. New chemotherapeutic drugs enter the market over time due to research and development by scientists and pharmaceutical companies, and scientists conduct clinical studies and collect data on their effectiveness. If the new drug is more beneficial than the old medicine, it replaces its place as a first -line treatment.
