Today women ask us not only to be cured but also the preservation of their body; this is one of our most important endpoints in modern radiotherapy treatments. The radiotherapy-induced skin toxicity remains a major clinical problem that affects many patients with breast cancer undergoing adjuvant radiotherapy [18]. Anyway there is a growing emphasis on prevention and treatment of side effects induced by radiation therapy; this attention has derived many studies dealing about the treatments and substances that can protect healthy organs from radiation therapy side effects.. Surely the breast volume has a great impact on the incidence and the level of skin toxicity, but also the breast volume receiving dose-points equal or greater than 107% of the one prescribed has an impact in the arising of side effects. Thats because many studies aimed to find appropriate prevention methods for damages are born. These methods seemed to be helpful in 25% of patients with breast cancer who presented a high ...
Radiotherapy is a type of treatment that uses pulses of radiation to destroy cancer cells. There are a number of ways it can be used to treat people with lung cancer.. An intensive course of radiotherapy, known as radical radiotherapy, can be used to try to cure non-small-cell lung cancer if the person isnt healthy enough for surgery. For very small tumours, a special type of radiotherapy called stereotactic radiotherapy may be used instead of surgery.. Radiotherapy can also be used to control the symptoms and slow the spread of cancer when a cure isnt possible (this is known as palliative radiotherapy).. A type of radiotherapy known as prophylactic cranial irradiation (PCI) is also sometimes used during the treatment of small-cell lung cancer. PCI involves treating the whole brain with a low dose of radiation. Its used as a preventative measure because theres a risk that small-cell lung cancer will spread to your brain.. The three main ways that radiotherapy can be given are described ...
Polls show that the public do not recognise radiotherapy as a modern form of cancer therapy, and many would describe it as frightening. Yet radiotherapy is one of the most effective cancer treatments available, and a staggering array of new developments should allow radiotherapy to become increasingly personalised to individual cancer patients.. Major advances, such as Intensity Modulated Radiotherapy (IMRT), proton therapy, Cyberknife technology and research combining radiotherapy with MRI imaging, viral therapy, and chemotherapy, promise to revolutionise radiotherapy in the future.. Leading experts in radiotherapy came to the SMC discuss things such as:. ...
Results Out of the 12 patients in the study, 6 did not receive radiotherapy either because they elected for subsequent radical surgery (3 patients) or were unfit for further treatment and underwent close follow-up (3 patients).. In the radiotherapy group, 2 patients had pre-op Long-Course Chemo-radiotherapy (LCCRT) with a good partial response, 2 were included in the national TEM and Radiotherapy in Early Rectal cancer (TREC) trial and had pre-op Short Course radiotherapy (SCRT) and 2 had adjuvant LCCRT + Papillon contact radiotherapy following TEM.. Median follow-up was 20 months. Patients not undergoing radial surgery had 3 monthly MR and sigmoidoscopy for 1 year and 6 monthly MR and sigmoidoscopy for a further 2 years.. In the no-radiotherapy group, 1 of the 3 patients who underwent subsequent radical surgery had involved mesorectal lymph nodes and 1 of those undergoing close follow-up without radical surgery developed mesorectal nodal recurrence. In radiotherapy group 1 patient, in the TREC ...
Post-operative radiotherapy is internationally accepted as standard practice in the management of high-risk endometrial cancer1. Whilst it has no proven impact on overall survival it significantly increases local control.. Conventional radiotherapy techniques (3-dimensional) utilise a 3 or 4 field beam arrangement to target the pelvis in order to treat those areas at risk of recurrence: the vagina, the parametrium and the pelvic lymph nodes. However, when using such a technique it is not possible to avoid irradiating sensitive normal tissues such as the bowel and bladder.. Toxicity data from international randomised control trials in endometrial cancer report significantly more haematological, gastrointestinal, genitourinary and cutaneous toxicites (all grades) in those who received pelvic irradiation compared to those who did not2,3. These trials delivered radiotherapy using 2 or 3-dimensional techniques.. Intensity Modulated Radiation Therapy (IMRT) is a newer but established radiotherapy ...
Post-radiation fractures after radiotherapy are prevalent in specific anatomic locations, such as the pelvis following urologic or gynecologic cancer treatment,...
Modern radiotherapy machines can now deliver highly targeted radiotherapy treatment. However, the use of high precision radiotherapy techniques is extremely demanding in terms of hours spent, from the physician who defines the tumour target and healthy tissues, to the physicist who has to calculate a plan of optimum beam angles and trajectories for the treatment, and the radiographer, who must ensure that the treatment is delivered accurately to the target every day during a six or seven week course of radiotherapy. Accel-RT is an innovative partnership between oncologists, physicists and computer scientists at the Universities of Cambridge and Oxford. Over the next three years the collaborators will develop software tools and processes that will speed up the process of planning of radiotherapy. Once completed, free software tools will be available to radiotherapy treatment centres. These tools will increase patient access to high precision radiotherapy by reducing the bottle-necks in the ...

In this manuscript, we show that treatment with low doses of fractionated radiotherapy leads to upregulation of PD-L1 expression on tumor cells secondary to CD8+ T-cell production of IFNγ. In models of melanoma, colorectal, and breast cancer, we demonstrate that the efficacy of radiotherapy can be enhanced through combination with αPD-L1 mAb, leading to the generation of memory immunity in LTS mice capable of protecting against tumor recurrence. Furthermore, our data reveal that dose scheduling may be critical for outcome with concurrent but not sequential therapy effective at improving local tumor control and survival.. Recent clinical trials have begun to evaluate blockade of the PD-1/PD-L1 axis with encouraging responses observed in multiple disease settings with mAb targeted against both PD-1 and PD-L1 (18-20, 24, 25). Despite this, combination approaches may be required to improve response rates and to generate durable antitumor immunity. We and others have demonstrated the potential to ...
... is used to treat conditions such as cancer, thyroid disorders and some blood disorders. It is used to treat about 40% of people with cancer. The length of each course of radiotherapy depends on the size of the cancer and where it is on the body.. During radiotherapy, controlled doses of high-energy radiation, usually X-rays, destroy cancer cells in the affected area.. Uses of radiotherapy. Radiotherapy is used for a number of different medical purposes including:. ...
A chemotherapy regimen consisting of procarbazine, CCNU, and vincristine administered following radiation therapy improved progression-free survival and overall survival in adults with low-grade gliomas, a form of brain cancer, when compared to radiation therapy alone. The findings were part of the results of a Phase III clinical trial presented today at the 2014 American Society of Clinical Oncology Annual Meeting by the studys primary author Jan Buckner, M.D., deputy director, Cancer Practice, at Mayo Clinic Cancer Center.
Radiotherapy is one of the most common therapeutic methods for treatment of many types of cancer. Despite many decades of development and experience there is much to improve, both in efficacy of treatment and to decrease the incidences of adverse healthy tissue reactions. Around 20 % of the radiotherapy patients show a broad range in the severity of normal tissue reactions to radiotherapy, and dose limits are governed by severe reactions in the most radiosensitive patients (, 5 %). Identification of patients with low, moderate or high clinical radiosensitivity before commencing of radiotherapy would allow individual adaptation of the maximum dose with an overall increase in the cure rate. Characterization of factors that may modify the biological effects of ionizing radiation has been a subject of intense research efforts. Still, there is no assay currently available that can reliably predict the clinical radiosensitivity. The aim of this work has been to investigate the role of oxidative stress ...
Radiotherapy to the breast can sometimes lead to long-term side effects. A few months after radiotherapy some women develop breathlessness (due to the effect of radiotherapy on the lung). This can usually be treated with a short course of steroids. In the longer term there may be some weakness of the ribs in the irradiated area, which makes them more likely to fracture than normal. If you have radiotherapy to your underarm (axilla) there is a very small risk of developing late side effects such as nerve pain, tingling, and weakness or numbness in the arm and hand (peripheral neuropathy ...

The long-term results of the RT01 trial, which looked at whether standard or higher doses of radiotherapy were best for treating localised and locally-advanced prostate cancer, were published in the Lancet Oncology on 26 February 2014.. The trial compared a 7.5 week course of radiotherapy (giving 74 Gy of radiation in total) with a 6.5 week course of radiotherapy (giving 64 Gy of radiation). The results show that, 10 years after treatment, men who had the higher dose of radiotherapy were less likely to have signs of their cancer coming back or getting worse. 55 per cent of men in the higher dose group had no signs of their disease getting worse, compared to 43 per cent who had the standard dose.. Men who received the higher dose were also less likely to need to start treatment with long-term hormone therapy within 10 years.. However, the trial found that there was no difference in how long men treated with the higher or standard doses lived. Men in both groups of the trial lived much longer than ...
This new volume in the Radiotherapy in Practice series provides a comprehensive and evidence-based guide to radiotherapy in the management of children and young people with cancer. It explains the roles of the various modalities of treatment available, including image-guided and intensity modulated radiotherapy, brachytherapy, proton beam therapy, and molecular radiotherapy, and aids selection of the most appropriate technique in different situations.
Back in 2016 I was diagnosed with a rare form of Bowel Cancer, there were only 2 cases of it at the hospital where I was under. My Oncologist explained all the details about the diagnosis but I think I found out more by doing my own research. As a part of my treatment I was offered chemo-radiation, this is a treatment that means I was to have radiotherapy alongside taking chemotherapy tablets.. Radiotherapy is the use of controlled, high - energy radiation. It is offered alongside chemotherapy as it makes the cancerous cells more sensitive to the radiation.. I was told that I would have radiotherapy first to try to shrink the tumour before surgery, as this would make it easier for the surgeon to remove it. My tumor measured at 3 cms and was close to my rectum, sitting on the sphincter muscle - which controlled the movement of the bowel. The tumor was very close to the skin, so close that it could be felt from the outside.. From receiving my diagnosis til the first day of my radiotherapy it took ...
MODEL RELEASED. Radiotherapy. Patient being prepared for radiotherapy. Laser cross-hairs are being aimed onto the site of her brain tumour. Once targeted, a radiotherapy machine will focus radiation at the tumour. The radiation will stop the tumours growth and hopefully destroy it. Brain tumours are abnormal growths in or on the brain that may or may not be cancerous. However, the pressure build-up they cause can be extremely serious and so they must be destroyed using radiotherapy. - Stock Image M705/0141
This will be a multi-center, open-label, single-arm, prospective study, in which up to 18 adult patients requiring radiotherapy for metastatic disease or for an inoperable primary tumor with no definitive curative treatment option,, will undergo a combination treatment of intravenously (IV) delivered PROMITIL and standard of care radiotherapy. The treatment regimen will involve administration of two PROMITIL doses, delivered at a 21-day interval, and a 30 Gy course of EBR delivered in 10 fractions (3 Gy/fraction), initiated 1-3 days after the first PROMITIL dose and completed within a 2-week period. Treatment safety will be assessed on a weekly basis throughout the two 21-day treatment courses (42 days) and throughout the follow-up period (up to Day 127). AEs will only be logged until 6 weeks after the last PROMITIL dose (up until Day 64). Disease status will be reevaluated between days 43-50 of the study, and every 6 weeks thereafter (Days 85 and 127±7 days). In addition, following completion ...

The modern day radiotherapy treatments are almost exclusively based on computed tomography (CT) images. The CT images are acquired using x-rays, and therefore reflect the radiation interaction properties of the material. This information is used to perform accurate dose calculation by the treatment planning system, and the data is also well suited for creating digitally reconstructed radiographs for comparing patient set up at the treatment machine where x-ray images are routinely acquired for this purpose.. The magnetic resonance (MR) scanner has many attractive features for radiotherapy purposes. The soft tissue contrast as compared to CT is far superior, and it is possible to vary the sequences in order to visualize different anatomical and physiological properties of an organ. Both of these properties may contribute to an increase in accuracy of radiotherapy treatment.. Using the MR images by themselves for treatment planning is, however, problematic. MR data reflects the magnetic properties ...
Of 178 eligible patients, 141 (79%) had localized disease and 37 (21%) had metastases at presentation. Their 5-year EFS was 51% (SE 5%) and 23% (SE 7%) respectively. The response rate to induction chemotherapy was 88% (28% complete, 60% partial), but after radiotherapy the response rate increased to 98%. Thirty-seven of the localized patients underwent resection, of whom 16 (43%) required postoperative radiotherapy; the 5-year EFS of these surgical patients was 80% (SE 7%). The remaining 104 localized patients were eligible for randomization or assignment to receive radiotherapy; the 5-year EFS of these patients was 41% (SE 5%), with no significant difference in EFS between those randomized to SF vs. IF. Site of primary tumor correlated with 5-year EFS: distal extremity 65% (SE 8%), central 63% (SE 10%), proximal extremity 46% (SE 8%), and pelvic-sacral 24% (SE 10%) (p=0.004). Initial tumor size did not correlate significantly with EFS. Patterns of failure among the 141 localized patients ...

Radiotherapy has been considered a local modality and outcomes have emphasized local and regional control of tumors. Recent data suggests that radiotherapy may activate the immune system and the combination of radiation therapy and immune therapies may have the potential to improve both local and distant control of tumor deposits. Below we review principals underlying the concepts of combining both modalities.
Radiotherapy, as part of initial first cancer management included external beam, brachytherapy or a combination of both. There was a variation in the use of radiotherapy across various cancer types. In this cohort, 60-80% of testicular (seminomas), brain, anal and laryngeal cancers were treated with radiotherapy, whereas less than 30% of non-small-cell lung and eye & orbit cancers were managed with radiotherapy. Yet, for every cancer type analyzed, the risk of second cancer was significant (Relative Risk, RR,1); the highest risk was for testicular (34%) and cervical(17%) cancers. However, of all the second cancers, only 8% could be attributed to radiotherapy during first cancer management. This is a much smaller percent than expected, and is a very good news for the radiology community. It helps communicate long-term risk of radiotherapy with respect to the potential benefit of tumor control and patient survival. Furthermore, the overall risk also decreases with time and by 15 years after the ...

All radiotherapy is targeted towards the tumour, but by using complex computer models the focus of this targeting can be improved ("stereotactic radiotherapy"). This approach allows a higher dose to be administered in a shorter time with the same side-effects. "Cyberknife" is an example of this form of therapy. While there are potential advantages from shorter treatment courses and perhaps fewer side-effects, there is no evidence as yet that it is more effective than standard treatments.. ...

Head and neck patients who undergo surgery first are more likely to complete radiation therapy, according to Seattle-based researchers. Megan Dann Fesinmeyer, PhD, MPH, and colleagues noted that radiation dose and treatment duration correlated with tumor control and survival, but that breaks in radiotherapy have been associated with inferior tumor control. 1
