Recommended: Effect of radiation

Radiation therapy uses high-energy ionizing radiation to kill the tumor cells and this procedure generally reduces the risk of cancer recurrence by approximately 70%. However, it often induces adverse side effects on normal tissues adjacent to the radiation site. For both of the above therapies the tumor should be within clinical detection range and accessible to therapeutic procedures. Chemotherapy is a major post-surgical treatment used to reduce the risk of cancer recurrence. Chemotherapy decreases the tumor size by affecting rapidly dividing and highly metabolizing cells, which are the main characteristics of malignant cells. A large number of chemotherapeutics are clinically available like Gemcitabine, doxorubicin, paclitaxel etc. In many

    The current standard of therapy is resection of the tumor plus radiotherapy and TMZ (E5). Multiple studies performed between 1976 and 1991 have led postoperative radiotherapy to be accepted as standard treatment (L12). The universal dosing schedule for radiotherapy in GBM is fractionated irradiation over 6-7 weeks for a total of 60 gray (Gy) (G7,M13). TMZ is an oral alkylating agent that can be used concomitant with radiotherapy and as an adjuvant. The European Organization for Research and Treatment of Cancer (EORTC) and the National Cancer Institute of Canada (NCIC) organized a study showing that adding TMZ to standard radiotherapy is beneficial to overall survival. This study enrolled 573 patients from 85 institutions and randomly assigned eligible patients to receive either standard radiotherapy alone or radiotherapy plus concomitant and adjuvant TMZ. There was a 37% decrease in relative risk of death and a median increase in survival of 2.5 months in patients treated with TMZ and radiotherapy when compared to radiotherapy alone (P<0.001). There are adverse effects with both RT and chemotherapy, but hematologic toxicities are more likely to occur in patients treated with both TMZ and RT (M13). This study maintained its validity after accounting for recursive partitioning analysis classifications (L12). The current standard dose of TMZ is 75 mg per square meter of body surface area daily during radiotherapy and then a dose of 150-200 mg per square meter of body surface area for 5 days of each 28-day cycle following RT (G7,M13).

  • Overview of Stereotactic Radiotherapy

    1469 Words  | 3 Pages

    There are essentially three main types of cancer treatments; surgery, chemotherapy, and radiation. Surgery allows doctors to effectively remove tumors from a clear plane. Chemotherapy uses drugs to treat the tumor; but often the drugs affect other healthy cells in the process. Using radiation as a treatment can be either precise or vague. Many health stigmas can come from the vague forms of radiation or conventional radiation therapy. Conventional radiation treats both the unhealthy and healthy cells, therefore exposing healthy cells to harmful radiation (Radiation Oncology, 2011, p.6). When healthy cells are exposed to gamma radiation they are also exposed to ionizing radiation. The ionization can cause “breakage of chemical bonds or oxidization (addition of oxygen atoms)” in a cell; the main impact of this is on a cell’s DNA, if two strands of DNA break it can result in “mutations, chromosome aberrations, ...

    ...rapy and surgery, its used only if the cancer comes back. Surgery is the treatment of injuries of the body by incision with instruments. Depending on what stage the cancer is in, the patient may need multiple surgeries to completely treat the cancer. For the later stages in the cancer, surgery is the most common treatment. The option to have surgery depends on the size and the location of the cancer. With all this being said, if the cancer is found early enough, there is a better chance of it getting cured. Some patients decide to use either chemotherapy or radiotherapy along with surgery, just to be safe. “For many patients, surgery will be combined with other cancer treatments, such as chemotherapy, radiation therapy or hormone therapy” (Cancer Treatment Centers Of America parag.3). By combining these treatments, there is a better chance of the cancer being cured.

    *** Once the patient is done with their treatments they may go into remission and be cancer free. They will then have three months check ups to do scans to see if the cancer is still terminated or if some cancer spots have appeared. A possibility that could happen after the treatments are done is that the cancer could come back and when this happens it is called recurrent. When the cancer shows up again it can be a local recurrence, distant recurrence, or regional recurrence. A local recurrence can be if the cancer reappears in the same spot as before or near that location. A distant recurrence is when the cancer reappears in some organs, usually the lungs, or the bones. It is very rare for a regional recurrence to happen because it is not

    The specific treatment required depends on the form of cancer, the health issues one might have in reaction to the treatment, and the progression of the illness. In a recent article, a doctor, and a registered nurse explain lung cancer and the types of treatments involved. The authors claim that, “There are four types of treatments used in the treatment of lung cancer, which include: chemotherapy, radiation therapy, targeted therapy and surgery” (Slatore and Lareau 2). Chemotherapy involves the use of medications to fight the disease, whereas radiation therapy is the use of radiation or rays that are used to diminish the size of tumors. Targeted therapy is also a contemporary treatment which involves medication that targets tumor growth, where surgery is used to remove tumors completely. Although all of these treatments are effective, the type of therapy depends on what kind of cancer the patient

    Because of this matter, it has been proven that there still might be a possible concern that the cancer will show once again. The chance of the cancer being gone, depends on the cancer the person has because others may be easier to cure. Cancer can be easily cured if it hasn’t spread entirely, that is if the cancer has been found early, which it can be a higher chance of curing it. The chances of curing cancer and treating it can also depend on the patient’s age and his/her state of health. For instance, it’s been said that “surgery may be more risky if you are elderly or in a poor health”.
