Cancer has become one of the leading cause of deaths. The conventional treatment modalities in treat-ing cancer includes Surgery, Chemotherapy, Radiation and Immuno therapy. Amongst this, radiation therapy is one of the frequently used treatment modality. 95 % of cancer patients receiving radiation therapy will develop some form of radiodermatitis, including erythema, dry& moist desquamation, ul-cerations, necrosis etc. This kind of reactions may lead to delay in the treatment, affects the quality of life, diminishes the cosmesis and causes functional deficits. Despite the prevalence of radiation derma-titis, there is no gold standard in the prevention and management of this condition. Ayurvedic treatment modalities has the potential in reducing the dermatological effects. Local treatment modalities like Lepa, Pichu, Parishek, Rasayanas, lifestyle management may help in ameliorating the dermatological effects. This article includes radiation induced dermatitis its stages its clinical manifestation and role of Ayurve-da in managing it.

Abstract Continued improvements in cancer therapies have increased the number of long-term cancer survivors. Radiation therapy remains one of the primary treatment modalities with about 60% of newly diagnosed cancer patients receiving radiation during the course of their disease. While radiation therapy has dramatically improved patient survival in a number of cancer types, the late effects remain a significant factor affecting the quality of life particularly in pediatric patients. Radiation-induced brain injury can result in cognitive dysfunction, including hippocampal-related learning and memory dysfunction that can escalate to dementia. In this article, we review the current understanding of the mechanisms behind radiation-induced brain injury focusing on the role of neuroinflammation and reduced hippocampal neurogenesis. Approaches to prevent or ameliorate treatment-induced side effects are also discussed along with remaining challenges in the field.

Information concerning radiation-induced malignancies comes from the A-bomb survivors and from medically exposed individuals, including second malignancies in radiation therapy patients. The A-bomb survivors show an excess incidence of carcinomas in tissues such as the gastrointestinal tract, breast, thyroid, and bladder, which is linear with dose up to about 2.5 Sv. There is great uncertainty concerning the dose-response relationship for radiationinduced carcinogenesis at higher doses. Some animal and human data suggest a decrease at higher doses, usually attributed to cell killing; other data suggest a plateau in dose. Modern treatment modalities such as passive proton therapy and intensity modulated radiation therapy (IMRT) produce large amounts of scatter, leakage and neutron radiation, which has been found to be directly proportional to the risk of second malignancy incidence. Organs closer to the target typically receive higher and less homogeneous doses of cell killing and repopulation effects play an increasing role. The most common type of cancer caused by radiation is sarcoma, which is typically a cancer of muscle, bone, or blood vessel origin. We reviewed the literature with key words "Radiation induced second malignancies, second primary tumour, second cancer" to find relevant articles describing risk, diagnosis and treatments of radiation induced second malignancies.Faridpur Med.

OBJECTIVEStenoocclusive cerebral vasculopathy is an infrequent delayed complication of ionizing radiation. It has been well described with photon-based radiation therapy but less so following proton-beam radiotherapy. The authors report their recent institutional experience in evaluating and treating children with radiation-induced cerebral vasculopathy.METHODSEligible patients were age 21 years or younger who had a history of cranial radiation and subsequently developed vascular narrowing detected by MR arteriography that was significant enough to warrant cerebral angiography, with or without ischemic symptoms. The study period was January 2011 to March 2019.RESULTSThirty-one patients met the study inclusion criteria. Their median age was 12 years, and 18 (58%) were male. Proton-beam radiation therapy was used in 20 patients (64.5%) and photon-based radiation therapy was used in 11 patients (35.5%). Patients were most commonly referred for workup as a result of incidental findings on surveillance tumor imaging (n = 23; 74.2%). Proton-beam patients had a shorter median time from radiotherapy to catheter angiography (24.1 months [IQR 16.8–35.4 months]) than patients who underwent photon-based radiation therapy (48.2 months [IQR 26.6–61.1 months]; p = 0.04). Eighteen hemispheres were revascularized in 15 patients. One surgical patient suffered a contralateral hemispheric infarct 2 weeks after revascularization; no child treated medically (aspirin) has had a stroke to date. The median follow-up duration was 29.2 months (IQR 21.8–54.0 months) from the date of the first catheter angiogram to last clinic visit.CONCLUSIONSAll children who receive cranial radiation therapy from any source, particularly if the parasellar region was involved and the child was young at the time of treatment, require close surveillance for the development of vasculopathy. A structured and detailed evaluation is necessary to determine optimal treatment.

Abstract Objectives To evaluate objective treatment success and subjective patient-reported outcomes in patients with radiation-induced urethral strictures undergoing single-stage urethroplasty. Patients and methods Monocentric study of patients who underwent single-stage ventral onlay buccal mucosal graft urethroplasty for a radiation-induced stricture between January 2009 and December 2016. Patients were characterized by descriptive analyses. Kaplan–Meier estimates were employed to plot recurrence-free survival. Recurrence was defined as any subsequent urethral instrumentation (dilation, urethrotomy, urethroplasty). Patient-reported functional outcomes were evaluated using the validated German extension of the Urethral Stricture Surgery Patient-Reported Outcome Measure (USS PROM). Results Overall, 47 patients were available for final analyses. Median age was 70 (IQR 65–74). Except for two, all patients had undergone pelvic radiation therapy for prostate cancer. Predominant modality was external beam radiation therapy in 70% of patients. Stricture recurrence rate was 33% at a median follow-up of 44 months (IQR 28–68). In 37 patients with available USS PROM data, mean six-item LUTS score was 7.2 (SD 4.3). Mean ICIQ sum score was 9.8 (SD 5.4). Overall, 53% of patients reported daily leaking and of all, 26% patients underwent subsequent artificial urinary sphincter implantation. Mean IIEF-EF score was 4.4 (SD 7.1), indicating severe erectile dysfunction. In 38 patients with data regarding the generic health status and treatment satisfaction, mean EQ-5D index score and EQ VAS score was 0.91 (SD 0.15) and 65 (SD 21), respectively. Overall, 71% of patients were satisfied with the outcome. Conclusion The success rate and functional outcome after BMGU for radiation-induced strictures were reasonable. However, compared to existing long-term data on non-irradiated patients, the outcome is impaired and patients should be counseled accordingly.

We commonly see patients presenting with either portal hypertensive gastropathy (PHG) or radiation gastritis. Radiation-induced hemorrhagic gastritis is an unusual lethal complication postradiation. Patients with preexisting PHG have very friable mucosa that can easily bleed after radiation for cancer treatment. There is an increased risk of bleeding with both entities present together. Our aim is to focus on treatment and possible prevention of gastrointestinal bleeding in patients with preexisting PHG undergoing radiation therapy for newly diagnosed cancer. Several therapies like prednisolone, argon plasma coagulation, laser coagulation have been proposed. There are no set guidelines for treatment. In these patients, if radiation therapy is indicated either for hepatic or gastrointestinal malignancy, it is suggested to premedicate with proton pump inhibitors or sucralfate. We describe a case of 73-year-old female who presented with upper gastrointestinal bleeding. She had liver cirrhosis secondary to nonalcoholic fatty liver disease and diagnosed with pancreatic cancer, for which she received chemoradiation. She was found to have both radiation gastritis and PHG with diffuse erythematous, edematous, congested mucosa with diffuse oozing blood in the antrum making it very challenging to treat.

Abstract Introduction Little has been published about the choroidal vascular changes that occur years after radiation exposure. The aim of this study was to review the histological changes observed in the choroidal vasculature following radiotherapy for uveal melanoma. Methods Records from a single institution were retrospectively reviewed from June 7, 2007 to June 7, 2017; 101 patients with a diagnosis of uveal melanoma that underwent enucleation had their records reviewed. Out of these, a total of 26 eyes had undergone plaque brachytherapy prior to enucleation, which had been performed at a mean time of 7.2 years (range from 0 years to 30 years) after the initial plaque placement. A histopathologic analysis was conducted on all 26 eyes with special emphasis on the choroidal changes. Of these 26 eyes, 18 demonstrated evidence of radiation-induced vasculopathy. Results Of the 18 eyes, 10/18 (55%) had radiation retinopathy and 16/18 (89%) had radiation choroidal vasculopathy. One patient had a phthisical eye, and the choroid could not be evaluated because the characteristics of the vasculature could not be determined. Nine cases had vitreous hemorrhage (50%), all cases had radiation retinopathy, and 8/9 (89%) had radiation choroidopathy. Of the 16 cases with radiation choroidal vasculopathy, 3/16 (19%) had only intratumoral radiation choroidal vasculopathy, 3/16 (19%) had only extratumoral radiation choroidal vasculopathy, and, thus, 10/16 (32%) had both intratumoral and extratumoral radiation choroidal vasculopathy. In patients with radiation choroidal vasculopathy, 2/16 (13%) had hyalinization of the choroidal vessels. Another 3/16 (19%) cases with radiation choroidal vasculopathy had ectatic vessels. The other 11/16 (68%) had evidence of both hyalinization of the choroidal vessels as well as ectatic vessels in the choroid. Histological evidence of radiation retinopathy and choroidopathy were seen in 69% of eyes enucleated after receiving radiation therapy, which, in some cases, also had vitreous hemorrhage. Polypoidal choroidal vasculopathy, choroidal neovascularization, and retinal choroidal anastomoses (RAP-type lesions) were seen in 12 of the 16 eyes (75%). Discussion/Conclusion Irradiation of malignant tumors of the eye causes not only radiation retinopathy but also radiation choroidopathy. The role of radiation choroidopathy in the subsequent visual loss following radiotherapy and the role of anti-VEGF therapy needs to be recognized and distinguished from radiation retinopathy. Our data adds to the prior limited knowledge that radiation affects the choroid and can induce specific phenotypes similar to the clinical spectrum of CNV, PCV, and RAP.

Abstract BACKGROUND As the outcome of pediatric brain tumors improves, late recurrence and radiation-induced tumor cases are more likely to occur, and the number of cases requiring re-irradiation is expected to increase. Here we report two cases performed intracranial re-irradiation after radiotherapy for pediatric brain tumors. CASE 1: 21-year-old male. He was diagnosed with craniopharyngioma at eight years old and underwent a tumor resection. At 10 years old, the local recurrence of suprasellar region was treated with 50.4 Gy/28 fr of stereotactic radiotherapy (SRT). After that, other recurrent lesions appeared in the left cerebellopontine angle, and he received surgery three times. The tumor was gross totally resected and re-irradiation with 40 Gy/20 fr of SRT was performed. We have found no recurrence or late effects during the one year follow-up. CASE 2: 15-year-old female. At three years old, she received 18 Gy/10 fr of craniospinal irradiation and 36 Gy/20 fr of boost to the posterior fossa as postoperative irradiation for anaplastic ependymoma and cured. However, a anaplastic meningioma appeared on the left side of the skull base at the age of 15, and 50 Gy/25 fr of postoperative intensity-modulated radiation therapy was performed. Two years later, another meningioma developed in the right cerebellar tent, and 54 Gy/27 fr of SRT was performed. Thirty-three months after re-irradiation, MRI showed a slight increase of the lesion, but no late toxicities are observed. CONCLUSION The follow-up periods are short, however intracranial re-irradiation after radiotherapy for pediatric brain tumors were feasible and effective.

Radiations dissipated are high energy waves used mostly as treatment intervention in controlling the unwanted multiplication of cell. About 60%–65% of cancer treatment requires radiation therapy and 40%–80% of radiation therapy causes RINV which are true troublemakers. Radiation therapy (RT) is targeted therapy mostly used to treat early stages of tumour and prevent their reoccurrence. They mainly destroy the genetic material (DNA) of cancerous cells to avoid their unwanted growth and division. The RINV affects the management and quality of life of patients which further reduces the patient outcome. RINV depends on RT related factors (dose, fractionation, irradiation volume, RT techniques) and patient related factors like (gender, health conditions, age, concurrent chemotherapy, psychological state, and tumour stage). RT is an active area of research and there is only limited progress in tackling the RINV crisis. Advanced technological methods are adopted that led to better understanding of total lethal doses. Radiation therapy also affects the immunity system that leads to radiation induced immune responses and inflammation. Radio sensitizers are used to sensitize the tumour cells to radiations that further prevent the normal cell damage from radiation exposure. There is a need for future studies and researches to re-evaluate the data available from previous trials in RINV to make better effective antiemetic regimen. The article focuses on radiation therapy induced nausea and vomiting along with their mechanism of action and treatment strategies in order to have a remarkable patient care.

Background:The treatment of patients presenting with cervicogenic dizziness (CGD) may be challenging. Indeed, there is no consensual treatment approach for CGD, nor is there no gold-standard assessment for diagnosis.Objectives:Our study aimed to assess the management of CGD by rheumatologists versus otorhinolaryngologists.Methods:We conducted a cross-sectional study including Tunisian doctors dealing with CGD. Rheumatologists (RTO) and otorhinolaryngologists (ORL) were invited to answer a questionnaire via google form about CGD daily management. Outcomes of interest were treatment modalities.Results:The study included 30 RTO and 32 ORL. Most of the doctors (RTO, vs ORL) were females (88.3%, vs 56.3%), aged between 35 and 45 (43.3%, vs 62.5%), and worked at a private practice (33.3%, vs 59.4%). The number of patients diagnosed with CGD by RTO was as follows: 1-2 per year (33.3%), 1-2 per month (18.8%), 1-2 per week (20%), less than one patient a year (10%) and none in 3.3% of cases. The number of patients diagnosed with CGD by ORL was as follows: 1-2 per year (50%), 1-2 per month (33.3%), 1-2 per week (6.2%), less than one patient a year (15.7%) and none (9.4%). Most patients presenting with CGD were females in both groups (93.1%, vs 82.8% respectively) with a mean age between 36 and 65 (79.3%, vs 82.1%). Most of the respondents declared treating patients with CGD (93.1%, vs 79.1%). Regarding treatment modalities, physical therapy was the most prescribed in both specialties (81.5% and 48.3%, respectively). Only RTO (18.5%) prescribed manual therapy. Concerning medical treatment, anti-inflammatory were the most prescribed drugs in both groups (92.6, and 34.5%, respectively). Sixty-seven percent of RTO prescribed anti-vertigo medication. Interestingly, it was the least prescribed drug by ORL (6.9%). Only RTO (59.3%) prescribed Muscle relaxants.Conclusion:Despite the disparities in the management of CGD, physical therapy remains the first prescribed treatment by Tunisian doctors. Further studies are needed to establish a consensus to treat CGD.Disclosure of Interests:None declared

Abstract INTRODUCTION Medulloblastoma is one of the most common malignant brain tumors in children. To date, the treatment of average-risk (non-metastatic, completely resected) medulloblastoma includes craniospinal radiation therapy and adjuvant chemotherapy. Modern treatment modalities and now risk stratification of subgroups have extended the survival of these patients, exposing the long-term morbidities associated with radiation therapy. METHODS We performed a single-arm, multi-institution study, seeking to reduce the late effects of treatment in patients with average-risk medulloblastoma prior to advances in molecular subgrouping. To do so, we reduced the dose of craniospinal irradiation by 25% to 18 gray with the goal of maintaining the therapeutic efficacy as described in CCG 9892 with maintenance chemotherapy. RESULTS 28 patients aged 3–30 years were enrolled across three institutions between April 2001 and December 2010. Median age at enrollment was 9 years with a median follow-up time of 11.7 years. The 3-year relapse-free (RFS) and overall survival (OS) were 78.6% (95% CI 58.4% to 89.8%) and 92.9% (95% CI 74.4% to 98.2%), respectively. The 5-year RFS and OS were 71.4% (95% CI 50.1% to 84.6%) and 85.7% (95% CI 66.3% to 94.4%), respectively. Toxicities were similar to those seen in other studies; there were no grade 5 toxicities. CONCLUSIONS Given the known neurocognitive adverse effects associated with cranial radiation therapy, studies to evaluate the feasibility of dose reduction are needed. In this study, we demonstrate that select patients with average-risk medulloblastoma may benefit from reduced craniospinal radiation dose of 18 gray without impacting relapse-free or overall survival.
