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 ...

Radiotherapy 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

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 ...
A Canadian research team announced that it has found the reason for the appearance of pulmonary fibrosis in a number of lung cancer patients who underwent thoracic radiotherapy. They found a connection between genes on a certain chromosome and the development of lung injuries triggered by radiation. The researchers were investigating chromosome 6, one of the 23 pairs of DNA molecules found […]
Being told that one has Cancer is not much fun, and when I was diagnosed nearly 18 months ago it was inevitably a shock. This was compounded by the certainty of an operation (double mastectomy), possibility of chemotherapy and almost certainty of Radiotherapy.. The Chemo I escaped, the operation went well, but it was the anticipation of the Radiotherapy which, for me, presented the worst fears. It was not a fear of nuclear medicine, it was the side-effects: I was almost promised these...blistering, weeping skin, bright red and extremely itchy patches around the treated areas. The fact that these things would blow up AFTER the treatment was ended made it seem worse, treatment that in itself was fairly grim - having to lie unnaturally still for what seemed like ages: having ones body heaved around to position it and not being allowed to help - incredibly undignified.. It was just before I started Radiotherapy, however, that I was introduced to someone who had travelled an identical path to ...

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.. ...

Radiation therapy, or radiotherapy, is the medical use of radioactive particles to kill and/or control the growth of malignant (cancerous) cells.
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

The present study presents a case of peritoneal malignant mesothelioma (PMM) following radiation therapy for cervical cancer. A 34‑year‑old Japanese woman, without asbestos exposure, was referred to the Department of Gynecologic Oncology, Saitama Medical University International Medical Center due to a cervical mass, and was diagnosed with cervical squamous cell carcinoma (SCC). The serum levels of tumor markers, including SCC antigen and cancer antigen 125 (CA125) were 229.0 ng/ml and 54.4 U/ml, respectively. The patient underwent concurrent chemoradiotherapy (CCRT), and a complete response was achieved. After 54 months, ascites was found at the rectouterine pouch, but peritoneal cytology suggested reactive mesothelial cell. After 62 months of CCRT, magnetic resonance imaging revealed masses in both the salpinges. The serum levels of SCC and CA125 were 0.9 ng/ml and 506.1 U/ml, respectively. Following this, left salpingectomy and peritoneal biopsy were performed laparoscopically. Histologic ...

Over the course of its 100-year history, the centre for radiation oncology and tumour research has become one of the worlds largest and most modern facilities for radiooncology and radiotherapy. Radiation oncology is one of the three main pillars of cancer treatment together with surgery and chemotherapy.. More than 3,500 people are treated at the centre every year by specialist doctors and nurses, on both an inpatient and outpatient basis. All modern radiotherapy procedures for the treatment of tumours are offered at Heidelberg University Hospital. The department currently has eight radiotherapy systems including two tomotherapy units (which surround the patient like a CT scan), plus a facility for intraoperative radiotherapy in the departments of surgery and gynaecology. In addition, we offer the complete spectrum of brachytherapy, in which a localised radiation source is positioned near the tumour.. The Heidelberg Ion Therapy Centre (HIT), the only centre of its kind in Europe, represents a ...
Cardiovascular diseases following radiotherapy are major secondary late effects raising questions among the scientific community, especially regarding the dose-effect relationship and confounding risk factors (chemotherapy, cholesterolemia, age at treatment, blood pressure,…). Post-radiation coronary diseases are one of the main causes of cardiac morbidity. Some approximations are made when coronary doses due to radiotherapy are estimated, especially regarding the morphology. For retrospective studies with old medical records, only radiographs are usually available with sometimes some contours made with a simulator. For recent medical records, CT scans displaying the anatomy in 3D are used for radiotherapy simulation but do not allow the coronary artery visualization due to low resolution and contrast. Currently, coronary doses are barely assessed in clinical practice, and when it is done, anatomical prior knowledge is generally used. This thesis proposes an original approach based on hybrid ...
Purpose: Radiotherapy has reduced local recurrence of rectal cancers, but the result is not satisfactory. Further biologic factors are needed to identify patients for more effective radiotherapy. Our aims were to investigate the relationship of cyclooxygenase-2 (Cox-2) expression to radiotherapy, and clinicopathologic/biologic variables in rectal cancers with or without radiotherapy. Methods and Materials: Cox-2 expression was immunohistochemically examined in distal normal mucosa (n = 28), in adjacent normal mucosa (n = 107), in primary cancer (n = 138), lymph node metastasis (n = 30), and biopsy (n = 85). The patients participated in a rectal cancer trial of preoperative radiotherapy. Results: Cox-2 expression was increased in primary tumor compared with normal mucosa (p < 0.0001), but there was no significant change between primary tumor and metastasis. Cox-2 positivity was or tended to be related to more p53 and Ki-67 expression, and less apoptosis (p ≤ 0.05). In Cox-2-negative cases of ...
January 31, 2011 - An oncology systems provider has launched The Year of Radiotherapy, an initiative to raise awareness of radiotherapy as a cost-effective, cutting-edge treatment that can help cure cancer. Oncology Systems Limited (OSL) launched the program in response to data from Cancer Research UK.. According to figures published by Cancer Research UK, only one in 10 people know that radiotherapy helps cure 40 percent of cancer patients. A report from the national charity estimates that only 38 percent of cancer patients in England are getting radiotherapy, although research shows that up to 50 percent might benefit. We need to dispel the myths about radiotherapy and associated side effects and make people more aware of the benefits of the latest treatments, said Julie Mead, clinical director of OSL. But we also need to make sure that these treatments are available across the country. The U.K. lags behind America and Europe in introducing the new, more targeted radiotherapy technology ...

While x-rays can be teratogenic in humans, the consequences of in utero exposure to radiotherapy are unclear in terms of dose and duration. Many of the data on the effects of exposure to ionizing radiation during pregnancy have arisen from studies on survivors of the atomic bombs used in World War II. Exposure to high doses of ionizing radiation has been associated with an increased risk of fetal malformations, mental retardation, growth retardation, and, in particular, small head circumference.1 4 However, only a few cases have been reported of pregnant mothers treated for cancer with radiotherapy applied to the upper body. Although some of these cases have reported normal outcomes, the offspring follow-up was too short to draw ultimate conclusions.. To highlight the complexities involved, we will present the case of the woman introduced in the Question. She received radiation for 4 weeks during the first trimester of pregnancy and decided to continue the pregnancy to term, as no fetal ...

Over the course of its 100-year history, the centre for radiation oncology and tumour research has become one of the worlds largest and most modern facilities for radiooncology and radiotherapy. Radiation oncology is one of the three main pillars of cancer treatment together with surgery and chemotherapy.. More than 3,500 people are treated at the centre every year by specialist doctors and nurses, on both an inpatient and outpatient basis. All modern radiotherapy procedures for the treatment of tumours are offered at Heidelberg University Hospital. The department currently has eight radiotherapy systems including two tomotherapy units (which surround the patient like a CT scan), plus a facility for intraoperative radiotherapy in the departments of surgery and gynaecology. In addition, we offer the complete spectrum of brachytherapy, in which a localised radiation source is positioned near the tumour.. The Heidelberg Ion Therapy Centre (HIT), the only centre of its kind in Europe, represents a ...

A pragmatic, randomised controlled trial of external beam radiotherapy plus SEMS versus SEMS alone in 396 patients with oesophageal cancer. Radiotherapy will be given as an outpatient either as five treatments over one week, or ten treatments over two weeks. Questionnaires assessing quality of life and cost effectiveness will be completed at weeks two, four, eight and twelve and then monthly for up to one year. Semi-structured interviews will be held with: i) trial participants to explore their experiences while on the trial; ii) patients who decide not to take part in the trial to explore reasons for non-consent.. ...
r.lost cancer patients may need external beam radiotherapy at certain times. Sufficient exposure of malignant cells and better avoidance of surrounding healthy tissues are necessary in order to minimise damage to non-cancerous regions. .Therefore, accurate patient positioning and proper radiation directions as well as dose distributions are crucial. A vital part of external beam radiotherapy is the geometric verification of treatment delivery. This thesis extensively studied three-dimensional (3D) to two-dimensional (2D) image registration methods. The author has proposed two novel methods to register computerised tomography (CT) based volume image data acquired for treatment planning with orthogonal planar images acquired at treatment simulation, which are able to recover the transformation errors in full six degrees of freedom (three translations and three rotations). The first proposed method is a novel feature-based method. It is based on automatic or semi-automatic extraction of object ...
Radiotherapy can be used to cure or control cancer in the pelvic area. This type of treatment is called pelvic radiotherapy and it is used to treat a number of different cancers.
Radiotherapy is the use of radiation to treat conditions such as cancer. The most common technique exposes tumors to high energy photons (x-rays) and/or electrons while sparing normal tissues. Other uses are to prepare a patient for organ transplantation by suppressing immune response and to calm muscle twitches. The therapy can be delivered from the outside (external beam radiotherapy), by radioactive implants placed in the body (brachytherapy), or during surgery (interoperative). Other types of radiotherapy such as proton therapy and neutron therapy -- available at very limited centers -- have their own distinct advantages and disadvantages.
A combination of a Virtalis ActiveWall and Virtual Environment Radiotherapy Training (VERT) software is enabling radiotherapy treatments to be taught using VR technology, completely eliminating both time pressure and danger to patients.. Already in use at leading teaching hospitals across the world, most especially in the UK, the latest institution to take delivery of a VERT system is The University of Applied Sciences, Vienna.. The life-like stereoscopic VR software immerses the student into a typical treatment room at a 1:1 scale, featuring a virtual patient on a treatment table with the linear accelerator above. The student controls VERT using the same controller that is used for real linear accelerators, with the controller both able to move the both the virtual table and the linear accelerator in order to achieve the correct positioning of the patient. The radiotherapy beam is visible as a virtual light beam. CT-sectional images, organs and dose distribution in the body caused by the ...
From an etiology standpoint, the question in each case is whether the presentation is due to cardiotoxicity from cancer treatment or coronary artery disease (CAD) unrelated to prior cancer therapy. In the first case, the patient has a history of lung cancer with last chemotherapy and radiation 1.5 years ago. Although the exact regimen was not specified, conventional chemotherapy used in lung cancer treatment is unlikely related to angina based on the mechanisms and timing of last exposure.1 If the radiation therapy was left-sided, there is certainly concern for cardiotoxicity from radiation. The mean heart dose was not specified, however, delayed onset CAD related to radiation therapy might have played a role in plaque rupture. Although the incidence of ischemic events increases significantly much later, as most cases present at 5 years or later post-radiation exposure,2 it is plausible that exposure to therapeutic radiation might have increased the risk for a coronary event. Common risk factors ...

In this study, we demonstrate that SABR-induced antitumor immunity is tumor antigen-specific and that combination SABR and anti-PD-1 therapy is not restricted to tumor histology or host genetic factors. We show that PD-1 restrains the immune-mediated abscopal effect induced by local radiotherapy in a preclinical model. PD-1 blockade or deficiency can synergize with radiotherapy to induce tumor-specific CD8+ T-cell immunity and result in a clinical response in the secondary tumors outside of the radiation field.. The demonstration of radiotherapy-induced T-cell priming within the tumor by the sensitization of the tumor stroma (13) or at tumor-draining lymph nodes via activation of antigen-presenting dendritic cells (14), as well as the accumulation of effector CD8+ T cells inside the tumor microenvironment (15), supports the hypothesis that radiotherapy can elicit and enhance both the priming and effector phases of antitumor T-cell response. Consequently, if sufficient effector CD8+ cytotoxic ...

Immune checkpoint inhibitors are considered as a major advance in a variety of cancer diseases with dismal prognosis (1). Despite outstanding progress in melanoma and lung cancers, a majority of patients will nevertheless fail in achieving long-lasting responses. Associating radiotherapy with immunotherapy has shown synergistic effect and is now considered as a promising strategy to stretch both response and survival at bedside (2). However, combining radiotherapy and immunotherapy can be done following a variety of different modalities. Determining the exact scheduling of the radioimmunotherapy association is therefore critical, and standard empirical approaches (trial-and-error) will hardly meet the current requirements of fast-track approvals of novel therapies. In this respect, developing modeling and simulation tools able to describe biological and pharmacodynamics processes should help to better determine an optimal solution among numerous possibilities.. Radiotherapy is widely used in the ...
Objectives The clinical outcomes of patients treated with spatially fractionated GRID radiotherapy (SFGRT) for bulky tumors of the head and neck at a single institution were evaluated retrospectively. Endpoints of interest included tumor response, symptom improvement, treatment tolerance, and adverse events. Methods Institutional review board approval was obtained prior to study initiation. The institutional database was queried for patients with tumors of the head and neck treated with SFGRT between August 2007 and April 2015. Medical records of identified patients were reviewed for treatment details and clinical endpoints of interest. SFGRT was delivered in one fraction of 15 gray (Gy) or 20 Gy; 6 megavolt (MV) or 18 MV photon beams were passed through a multileaf collimator (MLC)-based or brass GRID template. All patients had a planned course of conventionally-fractionated external beam radiotherapy (EBRT) to begin on the day following SFGRT delivery. Results Twenty-one consecutive
S&L begin their 1967 paper with a cleverly formulated hypothetical example of an RCT of two approaches to treating a particular but unspecified cancer: radiotherapy alone versus radiotherapy preceded by 30 days of sensitizing chemotherapy. They argue that if the purpose of the trial is explanatory (purely to test the hypothesis that sensitizing chemotherapy improves the action of radiotherapy) then the radiotherapy in each arm of the trial should be given at the same time. This would mean that in the radiotherapy alone group, it would be delayed until day 31, to make it exactly comparable to the radiotherapy delivered post chemotherapy. This approach renders the two arms comparable in relation to the radiotherapy, the only difference being the presence or absence of chemotherapy. It thus tests directly the hypothesis that chemotherapeutic pre-sensitization increases the effect of follow-on radiotherapy.. If, however, the purpose of the trial is pragmatic, that is, simply to identify which ...

The Calypso System, with its GPS for the Body technology, utilizes miniature implanted transponders (grain of rice size) to provide precise, continuous information on the location of the tumor during external beam radiation therapy. Any movement by the patient, including internal movement of the tumor, may cause the therapeutic radiation treatment to miss its intended target and hit adjacent healthy tissue. In contrast to ionizing tumor targeting methods which cannot track a target in real-time, the Calypso System provides real-time tumor position information, thereby allowing physicians to deliver radiation directly to the tumor while sparing surrounding healthy organs from radiation exposure. Currently the Calypso System is cleared by the U.S. Food & Drug Administration (FDA) for use in radiation therapy for the prostate and prostatic bed; however, the technology is designed for body-wide applications and studies are underway using it in other locations in the body ...
Purpose: To evaluate the feasibility of delivering experimental radiation therapy to tumors in the mouse pancreas. Imaging and treatment were performed using combined CT (computed tomography)/orthovoltage treatment with a rotating gantry. Methods and Materials: After intraperitoneal administration of radiopaque iodinated contrast, abdominal organ delineation was performed by x-ray CT. With this technique we delineated the pancreas and both orthotopic xenografts and genetically engineered disease. Computed tomographic imaging was validated by comparison with magnetic resonance imaging. Therapeutic radiation was delivered via a 1-cm diameter field. Selective x-ray radiation therapy of the noninvasively defined orthotopic mass was confirmed using γH2AX staining. Mice could tolerate a dose of 15 Gy when the field was centered on the pancreas tail, and treatment was delivered as a continuous 360° arc. This strategy was then used for radiation therapy planning for selective delivery of therapeutic ...

Researchers in this study used state-of-the-art artificial intelligence to highlight which information might predict sensitivity to the side effects of prostate radiotherapy. In particular, specific genetic characteristics - SNPs (single nucleotide polymorphisms) - were predictive of a patient suffering rectal bleeding.. At the moment there is no way to adjust doses of radiotherapy according to how sensitive a patient might be to the side effects. This means that while some men are receiving too much and suffering side effects, some are given too little and this compromises the chances of successful treatment. Side effects include bowel, urinary and sexual dysfunction and can be difficult for patients to tolerate and can persist after treatment.. The researchers suggest that with further validation, this information could be used to create personalised treatment plans for prostate cancer patients. The technique could also be applied to many other types of cancer that are treated with ...

Date: 22 August-27 September 1996 Location: San Jose, Costa Rica Type of event: radiotherapy accident Description:. An error in the calibration of a cobalt-60 radiotherapy unit in Costa Rica resulted in overdosages of about 60%. The equipment change that produced the error occurred on 22 August, with the first treatments administered on 26 August. Of 42 patients that died through 7 July 1997, 3 died probably as a direct result of radiation exposure and 4 more with radiation exposure a contributing cause. Another 22 died probably of their disease and not of radiation exposure. Of the surviving overexposed patients, 4 suffered catastrophic consequences, 16 more severe effects, 26 had lesser effects, and 22 had no effects. Some sources attribute 17 deaths to the misadministrations. Consequences: 7 fatalities, 81 injuries. References: ...
Most cancer treatments damage healthy cells as well as cancer cells; this is the main cause of side effects. Side effects vary depending on the treatment used and everyone reacts differently. Chemotherapy targets rapidly dividing cells, hence the lining of the mouth and digestive tract, the hair, skin and bone marrow are all affected. Radiotherapy damages normal cells in and around the treated area. Biological therapies may also cause side effects. Most side effects disappear within a few weeks of treatment finishing.. Leukaemia treatment often involves having several types of drug at the same time, possibly in combination with radiotherapy, so it can be difficult to know which treatment is causing what side effect. Side effects from high dose chemotherapy or total body irradiation (TBI) given in preparation for a stem cell transplant are more severe than those from standard chemotherapy or radiotherapy regimens.. Tiredness. Chemotherapy and radiotherapy can cause tiredness making people feel ...
