First Of All What Is The Radiation Therapy? (Introduction) The radiation therapy or the radiotherapy is using ionizing radiation is part of cancer treatment to kill the malignant cells, and is using the high energy to shrink the tumors such as : x-ray, gamma ray, and charged particles this is for cancer treatment. Radiation therapy is a commonly applied to the cancers tumor because is for its abele to be cell growth. Ionizing radiation working by damaging the DNA of cancerous tissue leading to
increasing. In order to evaluate the feasibility of utilizing radiotherapy on Hepatoblastoma (HB), here we conducted a vitro experiment to detect the radiosensitivity of a HB cell line Huh-6. Materials and methods: Cell proliferation, morphology change, cell apoptosis and cell cycle of Huh-6 cells received gradient X-ray irradiation (0 Gy, 1 Gy, 2 Gy, 4 Gy and 8 Gy) were systemically studied with CCK-8 assay, microscopy, Annexin V/7-ADD and PI single staining respectively. Results: The inhibition of proliferation
cancer research uk). Almost two-thirds of all cancer patients receive some form of radiation therapy during the course of treatment predominantly with external-beam photon therapy (ref 40). Proton beam therapy (PBT) is a novel form of external beam radiotherapy technique that utilises positively charged particles in cancer management (ref required). However, the idea of using charged particles for cancer treatment is not new. Robert R. Wilson was a famous American phycist who proposed that, heavy particles
IMRT patients but remained within the dose TD 5/5 and Quantec constraints6. For the contralateral parotid, the mean dose for the IMRT was 1707 cGy compared to the wedged pair dose of 294cGy. The Quantec mean dose for unilateral parotid is 2000cGy and the TD 5/5 is 3200 cGy. Both are within limits to prevent xerostomia. The submandibular is another area that can cause dry mouth if the dose is over the TD 5/5 of 3900 cGy. For the IMRT the mean dose for the contralateral submandibular was 1788 cGy
rhabdomyosarcoma (RMS) (65–70% event-free survival rate) [2, 3]. Though EWS and RMS are considered radiosensitive, the proportion of patients whose primary tumors are treated with external-beam radiotherapy (EBRT) alone has steadily declined over the past 30 years [4]. Increased awareness of the late effects of radiotherapy (particularly second malignancies and growth disturbances) and advances in imaging and orthopedic surgery has increased the use of surgical management for these tumors [5]. Due to the fact
quite sever. This paper will discuss the process of metastasis, the aetiology and pathophysiology of bone metastases, and the changes that occur within bone due to metastatic spread. It will outline bone metastases signs and symptoms, and discuss radiotherapy treatment options based on patient assessments, focussing
of tumor metastasis and recurrence. Radiotherapy is an important treatment for malignant tumors, but the development of resistance to radiation often leads to treatment failure. Recent studies have shown that cancer stem cell is a class of radiation resistant cell group, and radiation resistance might be attributable to the presence of cancer stem cells. As a result, the function and meaning of cancer stem cells have received tremendous attention in radiotherapy. The special DNA damage repair ability
for, in addition, which disorders have been attempted to be treated with this technique already, and have there been any successes with this treatment technique. Finally, have any ill effects, short or long term, been observed in patients treated with this gene therapy technique? If so, what are they, are these effects irreversible, and have there been any studies into the
Introduction Treating locally advanced rectal cancer includes radiotherapy (RT), chemotherapy (CT), chemoradiotherapy (CRT), surgery, and subsequent incorporation of molecularly targeted agents. With multimodality treatment, local recurrence rates became less than 10% with the predominant mode of failure is the development of distant metastases (30–35%). Therefore, the addition of induction CT is not aimed to improve local efficacy, but to better control distant disease [1, 2]. The neoadjuvant RT/CRT
There are three different treatments for Hodgkin and most patients respond well, chemotherapy, radiotherapy and stem cell transplant ("Leukaemia & Lymphoma Research"). Chemotherapy is the main combination of anti-cancer drugs. To have the best result these drugs need to be taken in a sequence. Due to specific diagnosis and stages of their disease patients will be given different protocols. Radiotherapy for some patients could be used along with chemotherapy. This uses high energy rays to kill cancer
