Prediction of radiobiological response is a major challenge in radiotherapy. Of several radiobiological models, the linear-quadratic (LQ) model has been best validated by experimental and clinical data. Clinically, the LQ model is mainly used to estimate equivalent radiotherapy schedules (e.g. calculate the equivalent dose in 2 Gy fractions, EQD2), but increasingly also to predict tumour control probability (TCP) and normal tissue complication probability (NTCP) using logistic models. The selection of accurate LQ parameters α, β and α/β is pivotal for a reliable estimate of radiation response. The aim of this review is to provide an overview of published values for the LQ parameters of human tumours as a guideline for radiation oncologists and radiation researchers to select appropriate radiobiological parameter values for LQ modelling in clinical radiotherapy. We performed a systematic literature search and found sixty-four clinical studies reporting α, β and α/β for tumours. Tumour site,
A study to evaluate the efficacy of Intensity Modulated Radiation Therapy (IMRT) as compared to Standard Conventional Radiotherapy Alone in the treatment of carcinoma cervix. Concomitant Weekly Cisplatin chemotherapy will be given as a routine, which is a standard of care today for early stage cervical cancers including stage IIB. The benefits of using IMRT in reducing radiation-induced toxicity are well known. Since this treatment modality has not yet been validated and studied in a randomized trial setting, the present study is being undertaken. The study arm of IMRT has the potential to reduce the toxicities by 15-20%, but is associated with labor intense procedure requiring many hospital visits before actual start of treatment ...

Dr. Grigsby has done a masterful job of summarizing current information on the use of radiation in the management of patients with endometrial carcinoma. In the summary, he offers clear recommendations as to the appropriate management of various subsets of patients-recommendations that are based, at least to some extent, on the data reviewed. Such decision-making based on often incomplete information is necessary in the absence of appropriately designed randomized trials addressing the specific clinical situation. It is important, however, to understand clearly what we actually know and what we deduce from bits and pieces of data. 1
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

Purpose of this work is to study clinical and dosimetric parameters impacting on late GI toxicity after prostate external beam radiotherapy (RT) and to establish multivariate normal tissue complication probability (NTCP) model for radiation-induced GI complications.Methods: A total of 57 men who had undergone definitive RT for prostate cancer were evaluated ...
Dosimetric comparison of non-coplanar three-dimensional conformal radiation therapy (nc3DCRT) planning and radio biologically optimized partial arc volumetric modulated arc therapy (VMAT) planning of unilateral brain tumours - A retrospective study
In the current study, we assessed the conventional BRT plan based on ICRU reference points and the CT-based BRT plan in patients with cervical cancer. We clearly demonstrated that tumor volume coverage was inadequate in the conventional plan compared to the CT-plan, and was inversely related with the volume of the target and the extension of tumor. With the conventional plan, the ICRU rectum and bladder point doses underestimated the actual rectum and bladder doses obtained from the CT-plan. Additionally, we demonstrated that more precise analysis of the dose received by certain volume of OARs can be accomplished by utilizing the DVHs on CT-plans, which may be of critical importance in regard to normal tissue tolerance limits.. After publication of ICRU 38 report, ICRU reference points for tumors, and reference dose points for bladder and rectum were used for defining the doses in conventional plans. But calculation of doses with these fixed reference points relative to applicators has certain ...

Doctors can use brachytherapy alone or in addition to external-beam radiation therapy to provide a "boost" of radiation to a tumor while sparing surrounding normal tissue. Brachytherapy may be able to deliver higher doses of radiation to some cancers than external-beam radiation therapy while causing less damage to normal tissue.. Several brachytherapy techniques are used in cancer treatment, based on locations of cancer, dose and period of treatment. Interstitial brachytherapy uses a radiation source placed within tumor tissue, such as within a prostate tumor. Intracavitary brachytherapy uses a source placed within a surgical cavity or a body cavity, such as the chest cavity, near a tumor. Episcleral brachytherapy, which is used to treat melanoma inside the eye, uses a source that is attached to the eye.. In interstitial brachytherapy, radioactive isotopes are sealed in tiny pellets, the size of a grain of rice. These seeds are placed in the body using delivery devices, such as needles, ...
The Radiation Therapy Oncology Group (RTOG) has successfully performed two multi-institutional prospective phase II trials. In RTOG 9610 trial [19], 86 patients were recruited and radiotherapy was delivered with 1.5 Gy/fraction twice per day, concurrently with hydroxyurea/5-fluorouracil (5FU) separated by 1 week of rest for 4 cycles. The late grade 3/4 toxicities were observed in 19.4% of patients. The OS was 15.2% at 2 years. There were 6 (7.6%) treatment-related deaths. The following RTOG 9911 study [20] was conducted from 2000 to 2003. It enrolled 105 patients who were treated with the identical radiation scheme (IMRT was included) but with a different concurrent chemotherapy agents (cisplatin/paclitaxel). The incidence of grade 3/4 late toxicities was high reported up to 33.8%. Eight patients (8%) of treatment-related deaths occurred. At 2 years, PFS and OS were 15.8% and 25.9%, respectively. These were relatively superior treatment outcomes (2-year OS 25.9% in RTOG 9911 vs. 15.2% in RTOG ...

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:. ...
The purpose of the study is to evaluate the effect of simvastatin in combination with radiotherapy on the clinical outcomes of patients with brain metastases.
In addition to improving overall five-year survival of average-risk patients to 85 percent, this group had an 83 percent rate of event-free survival and a rate of five-year, event-free survival of 70 percent for high-risk patients. Event-free survival means that a child did not have medical complications or relapse that required further treatment. Moreover, the improved treatment achieved a survival rate of 66 percent as compared to 30-40 percent among children whose cancer had spread.. The results of the current clinical trial, SJMB96, are especially significant because they represent a dramatic change from the 45 percent survival rate achieved two decades ago using just surgery and irradiation, according to Gajjar. The subsequent addition of chemotherapy before or after radiotherapy improved that survival rate to 65 percent for children aged 3 years or older who had medulloblastoma.. "We attribute our very promising results to the early use of high-dose radiotherapy after surgery - rather than ...
Patients treated with EBRT followed by SBRT boost received an initial course of EBRT to a total dose of 45 Gy in 25 fractions of 1.8 Gy with 15-MV photons, administered on consecutive work days. A 3D-conformal four-field box plan was utilized to include the prostate and pelvic nodes. Image-guided SBRT boost was planned using MultiPlan® (Accuray, Inc., Sunnyvale, CA) inverse planning, and delivered using the CyberKnife (Accuray, Inc.) with motion tracking of internal fiducial seeds. A detailed description of the CyberKnife system can be found elsewhere [23]. Patients underwent transperineal implantation of four fiducial seeds during EBRT, with two seeds placed at the prostate apex and two at the base. Treatment planning images were obtained one week after fiducial implantation to account for possible seed migration. Treatment was planned on CT images (1.5-mm cuts) with MRI fusion to soft tissue anatomy in the vast majority of patients. The prostate and proximal seminal vesicles were delineated ...
Patients with advanced cancer and short expected survival time may benefit from both symptom-relief and prevention by radiation therapy. In some cases, radiation treatment may also extend survival. Normal tissue has a greater ability to repair itself between fractionations compared to tumor tissue. Radiation therapy is therefore given with one or few fractions with good effect and little side effects. In this way, a high total dose is given to the tumor tissue but injury to healthy tissue is still limited. It is very important that acute side effects are minor and of short duration.. Palliative radiation therapy is used both for primary tumors, local recurrence, and metastases. ...
I had some hormone tablets to shrink the tumor, along with a hormone shot of Luprin. I felt like I had been kicked in the groin for a day, and then began to get hot flashes. They are big, but managable--now I can relate to the ladies far better! Then 6 weeks of radiation. I went religiously, five days per week. The side effects were minimal, with a slight bit of hair loss in the groin area, and no other external results. I needed to alter my diet to foods that firmed up my stool. It was tricky to get the right balance of foods to loosen vs. foods to firm up, but after a week or so I was in a good routine. After radiation was done, I needed to slowly transfer to a more normal and then a loosening diet. After 3 weeks of being off radiation, I now have normal food, including all the hotsause I want, but I have to take 4 prunes and about 2 ounces of bran spaced throughout the day. This keeps me loose. I had some internal anal hemroids which were pretty painful, which necessitated the loose stool. I ...

ed area around the radiation sources. Exposure to radiation of healthy tissues further away from the sources is therefore reduced. In addition, if the patient moves or if there is any movement of the tumour within the body during treatment, the radiation sources retain their correct position in relation to the tumour. These characteristics of brachytherapy provide advantages over EBRT - the tumour can be treated with very high doses of localised radiation, whilst reducing the probability of unnecessary damage to surrounding healthy tissues.[1]:Ch. 1[2] A course of brachytherapy can be completed in less time than other radiotherapy techniques. This can help reduce the chance of surviving cancer cells dividing and growing in the intervals between each radiotherapy dose.[2] Patients typically have to make fewer visits to the radiotherapy clinic compared with EBRT, and the treatment is often performed on an outpatient basis. This makes treatment accessible and convenient for many patients.[3][4] ...

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 ...
xHypoxia and repopulation of tumour clonogens are two important determinants of treatment outcome in radiotherapy. In general clinical evidence indicates that loco-regional control may be reduced with long overall treatment times and for tumours with low pre-treatment levels of oxygen. Experimental studies with normobaric carbogen and oxygen showed a two-fold enhancement of the efficacy of radiation in a mouse tumour model when combining oxygen with treatment acceleration. It was then demonstrated that substituting carbogen for oxygen and adding high-dose nicotinamide (NAM) further increased the effect. These findings became the basis for a multi-factorial approach designed to overcome the radioprotective effect of tumour repopulation and that of perfusion-limited and diffusion-limited hypoxia. The strategy, named ARCON, combines Accelerated Radiotherapy with CarbOgen and Nicotinamide.. Experimental evaluation of ARCON. The therapeutic potential of carbogen combined with NAM (CON) focusing on ...
When the testes contain some leukaemia cells, radiation treatment (radiotherapy) to the testes is recommended. The total radiation dose has to be spread out over quite a long time to make the individual treatments safe. We usually give 12 treatments, one every day (usually excluding weekends and bank holidays). At each session, the patient spends about ten minutes in the treatment room but most of this time is spent getting him/her into exactly the right position.. Radiotherapy does not hurt; it is rather like having an ordinary X-ray. So that we can treat both testes the patient must lie very still on their back. Lying still can be very difficult for some children, especially very young ones. Occasionally we have to use a general anaesthetic.. ...
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 ...
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 ...

Radiation therapy, or radiotherapy, is the medical use of radioactive particles to kill and/or control the growth of malignant (cancerous) cells.
To prepare for your treatment, you will have a session called a simulation. During this session, your radiation therapist decides which position youll need to be in during treatments. The radiation needs to be pointed at the exact same spot on your body each time. This is called your treatment field or port. After you lie in a comfortable position, the therapist will see where the radiation needs to go. Then he or she marks your body with ink that wont wash off easily in the shower. Lights from the machine will line up with these marks to be sure radiation is getting to the right part of your body.. ...
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
