Chemotherapy drugs are usually given in schedules. Chemotherapy schedules are designed to damage as many cancer cells as possible. Some of the drugs included in the regimen minimize the damage done to any healthy cell alongside. Doctors often ensure to administer a full dose of chemotherapy drug to make the best use of it. However, keeping a regular check on the side effects caused by chemotherapy becomes imperative. Doctors thus devise a regimen that manages these irregularities by giving the patient some rest periods to regain normalcy.

Chemotherapy ideally consists of few cycles separated by certain rest period that allows the patient to gain some strength intermittently. A cycle is typically given every 1, 2, 3, or 4 weeks, which lasts over a period of few weeks to months. Angiosarcoma is a critical type of cancer and once developed it takes years to treat. For such cancers, it is very essential to prepare special chemotherapy schedules. Angiosarcoma chemotherapy is Prescribed to the patients suffering from angiosarcoma, and its regimen is a bit different than the regular chemotherapy regimen schedules.

Chemotherapy is usually administered through an IV route. Doctors in such an instance might suggest implanting Vascular Access Device (VAD) that is grafted by a catheter in a large vein at the chest. Some doctors also prescribe induction chemotherapy for the patients, in whom the drugs are given in the form of injection.

The schedule of chemotherapy dose is proportionate to the type of cancer. Some cancer requires more time to heal. While others like seminoma could be treated readily. The regimen of chemotherapy is hence formulated keeping in mind the type of cancer that is inflicted.

All the cancer cells in a single tumor are not identical. Some cancer cells are receptive to one medicine while resistant to the other. Doctors thereby use a combination of drugs to diffuse the tumor. A set of chemotherapy drugs that are to be administered require a predefined regimen. Every drug has its own method of application. Duration of the dose or chemotherapy treatment schedule thereby varies with different combination of drugs being given.

Doctors usually formulate a full dose, on-schedule (FDOS) to garner the maximum efficacy of the treatment. Even a single unintended delay in a dose might reduce the impact of the chemotherapy. FDOS is intended to kill maximum number of cancer cells. If these doses are repeated over a short period of time interval it leaves very rare chances for the residual cancer cells to grow further. The tumor in such deprivation is likely to be destroyed by the natural immune system of the body.

Researchers are striving to find ways to shorten the interval between simultaneous doses of chemotherapy. Even increasing the intensity of the drug could help in treating cancer more readily. The side effects undoubtedly are to be minimized. Such chemotherapy schedules would increase the survival rate among cancer patients.
