Background: Neoadjuvant chemoradiotherapy (nCRT) decreases the risk of local recurrence after surgery in patients with locally advanced rectal cancer (LARC) and metformin is constantly gaining scientific interest due to its potentially radiosensitizing effect., Objective: This review article aims to better clarify the role of metformin as a radiosensitizer in patients with LARC undergoing neoadjuvant concurrent chemoradiotherapy., Methods: We used the PubMed database to retrieve journal articles and the inclusion criteria were all human studies that illustrated the effective role of metformin in the neoadjuvant setting of locally advanced rectal cancer., Results: Our search resulted in 17 citations, of which 10 eventually fulfilled the inclusion criteria of our study. Promising results (improved tumor and nodal regression as well as higher pathologic complete response rate) have been occasionally documented with metformin use in some of the included studies. However, regarding survival and all-cause mortality, no significant difference has been found., Conclusion: Metformin might constitute a highly promising radiosensitizer in neoadjuvant LARC treatment attracting much scientific interest. Due to the lack of studies with high evidence, further advanced research is required to enhance the existing knowledge about its potential value in this field., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Introduction: Women undergoing mastectomy choose to pursue breast reconstruction (BR) in order to reduce their body image distress.Adjuvant chest wall irradiation is associated with a negative cosmetic outcome. The aim of our review was to identify the optimal timing of BR relating to radiotherapy delivery., Materials and Methods: Using Cochrane Library, Embase, PubMed, Springer, Wanfang and CNKI, we performed a non-systematic review of articles published up to August 2021., Results: There is no hard evidence in favor of immediate, delayed or 2-stage BR when post-mastectomy radiation is indicated. Immediate and 2-stage BR seem to be valid alternatives to delayed BR., Conclusions: Further research is essential in order to assess clinician and patient reported aesthetic outcomes and determine the optimal timing of BR in view of post-mastectomy radiotherapy, in breast cancer survivors., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Background: Covid-19 vaccination has started in the majority of the countries at the global level. Cancer patients are at high risk for infection, serious illness, and death from COVID-19 and need vaccination guidance and support. Guidance availability in the English language only is a major limit for recommendations' delivery and their application in the world's population and generates information inequalities across the different populations., Methods: Most of the available COVID-19 vaccination guidance for cancer patients was screened and scrutinized by the European Cancer Patients Coalition (ECPC) and an international oncology panel of 52 physicians from 33 countries., Results: A summary guidance was developed and provided in 28 languages in order to reach more than 70 percent of the global population., Conclusion: Language barrier and e-guidance availability in the native language are the most important barriers when communicating with patients. E-guidance availability in various native languages should be considered a major priority by international medical and health organizations that are communicating with patients at the global level., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Backround: Radiation-induced oral mucositis consists of a series of relatively frequent side effects after head and neck cancer radiotherapy and has an adverse impact on both regular treatment process and the quality of life of patients., Objective: The purpose of the present review is to optimize the current management of radiation-induced oral mucositis in head and neck cancer patients., Methods: PubMed database research was performed on articles published since 2015 that demonstrated efficacy in the management of radiation-induced oral mucositis in head and neck cancer patients. The study selection included observational, prospective, comparative, randomized, double- blind, placebo-controlled or uncontrolled, and retrospective studies, as well as systematic reviews and metanalyses., Results: From the 931 citations obtained from the search, only 94 articles met the inclusion criteria, including mucosal protectants, anti-inflammatory agents, growth factors, and various miscellaneous and natural agents. Several methods, including both pharmacological and natural agents, have been proposed for the management of oral mucositis. In addition to the already known interventions with strong evidence, according to the Multinational Association of Supportive Care in Cancer and he International Society of Oral Oncology guidelines, further agents have been used. However, a great number of them lack clear evidence, which surely requires the design of more controlled clinical trials for a better assessment of the ideal methods., Conclusion: The management of oral mucositis constitutes an active area of research. In light of these results, it is aimed to illustrate those treatment strategies that are most effective regarding the treatment approach of oral mucositis., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Background: Radiation therapy is stressful for both the patient and family. After a child's cancer diagnosis, parents face the burden of dealing with fear, their children's needs and the unfamiliarity of radiotherapy procedure., Introduction: This paper aims to present methods to alleviate the total psychological stress those children and parents feel during the radiation course., Methods: A literature search was performed until January 2020., Result: Previous publications suggest a multidisciplinary proactive approach involving health professionals, patient, family, and extended family to lessen the stress associated with radiation therapy. A well-trained, specialist, healthcare radiotherapy-pediatric staff can help, educate and communicate effectively with the family. Maintaining the same health staff during radiotherapy creates intimacy and reduces anxiety. All necessary age-appropriate information as well as a list available with the most important things about the care-giving should be clearly written and easily accessible. An information exchange system among all the health specialists involved must be developed. Friendly and playful specialists are crucial in familiarizing the child with the computed tomography (CT) machines and radiotherapy process. A tablet with an educating application or machine models installed in the waiting area can be useful. Creative arts therapy may be a positive intervention. Maintaining a normal routine is vital for the psychological well-being of parents and children. A social worker may assist in regaining a good mental state., Conclusion: With ongoing age-appropriate information and psychological support throughout the whole radiation period, both parents and children will be more optimistic, strong and encouraged to fight for the child's and family's well-being., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Background: Radiation Therapy (RT) is an established treatment option for benign intracranial lesions. The aim of this study is to display an update on the role of RT concerning the most frequent benign brain lesions and tumors., Methods: Published articles about RT and meningiomas, Vestibular Schwannomas (VSs), Pituitary Adenomas (PAs), Arteriovenous Malformations (AVMs) and craniopharyngiomas were reviewed and extracted data were used., Results: In meningiomas RT is applied as an adjuvant therapy, in case of patientrefusing surgery or in unresectable tumors. The available techniques are External Beam RT (EBRT) and stereotactic ones such as Stereotactic Radiosurgery (SRS), Fractionated Stereotactic RT (FSRT), Intensity Modulated RT (IMRT) and proton-beam therapy. The same indications are considered in PAs, in which SRS and FSRT achieve excellent tumor control rate (92-100%), acceptable hormone remission rates (>50%) and decreased Adverse Radiation Effects (AREs). Upon tumor growth or neurological deterioration, RT emerges as alone or adjuvant treatment against VSs, with SRS, FSRT, EBRT or protonbeam therapy presenting excellent tumor control growth (>90%), facial nerve (84-100%), trigeminal nerve (74-99%) and hearing (>50%) preservation. SRS poses an effective treatment modality of certain AVMs, demonstrating a 3-year obliteration rate of 80%. Lastly, a combination of microsurgery and RT presents equal local control and 5-year survival rate (>90%) but improved toxicity profile compared to total resection in case of craniopharyngiomas., Conclusion: RT comprises an effective treatment modality of benign brain and intracranial lesions. By minimizing its AREs with optimal use, RT projects as a potent tool against such diseases., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Backround: Oral mucositis (OM) consists of a major side effect of radiotherapy (RT) in head and neck (H-N) cancer patients and natural honey is gaining more and more scientific interest due to its beneficial effects in tissue repair., Objective: The aim of this review is to better clarify the preventive/therapeutic role of honey in the management of OM in patients with H-N cancer undergoing RT with or without chemotherapy (CT)., Methods: We used the PubMed database to retrieve journal articles and the inclusion criteria were only reviews and meta-analyses that illustrated the effective use of honey for either the prevention or treatment of OM in H-N cancer patients receiving either RT alone or in combination with CT., Results: Our search resulted in 92 citations, of which 12 eventually fulfilled the inclusion criteria of our study. Decreased incidence and severity of OM, extended time of occurrence of mucositis, less weight loss and less treatment interruptions were occasionally documented with conventional honey use in the included reviews and meta-analyses. In contrast to conventional honey, manuka honey proved to be weak in improving OM management in the small number of included reviews in our search., Conclusion: Conventional honey might constitute a highly promising natural product against OM attracting much scientific interest due to its easy accessibility and low financial cost. Hence, the lack of studies with high evidence requires further advanced research to enhance the existing knowledge about the potential value of honey in radiation-induced OM in H-N cancer patients., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Background/aim: The evaluation of radiotherapy toxicity in oncologic IBD patients. Defining the optimal patient and treatment factors that would be able to reduce the risk to organs., Materials and Methods: A review of all published radiotherapy trials was performed to identify the clinical and treatment factors of inflammatory bowel disease's patients treated for different solid tumors., Results: Overall, acute (Grade ≥ 3) gastrointestinal complications attributable to RT ranged between 20-21% of the treated patients. A late Grade ≥ 3 gastrointestinal toxicity was developed in a range between 8-29%., Conclusion: A special attention should be given to the description of IBD location, activity status, concurrent chemotherapy, irradiation dose and technique, in order to minimize post-irradiation morbidity. It is not easy to distinguish late morbidity attributable to radiotherapy due to the IBD itself.

Hypofractionated irradiation has an established role in the palliative treatment of patients with advanced medically inoperable non - small cell lung cancer (NSCLC ) and poor performance status. Also hypofractionated radiotherapy merits careful consideration in the curative treatment of patients with Stage I and II disease using contemporary technology. The biological effect of radiation on tumours is increased as the overall treatment time is shortened. Hypofractionated field radiotherapy offers acceptable palliation with minimal toxicity. The rates of palliation for hemoptysis , chest pain , cough and dyspnea reported from studies with very short regimen ( 8,5 Gy x 2 ), are comparable to those of other trials that used more protracted palliative treatment . The observed toxicity is minimal, and no cases of oesophagitis, pneumonitis, or radiation myelopathy developed. The minimal toxicity is a reflection of both the low biologic total dose and the tight RT design. Therefore the radiation side effects appear to be related to the technique of RT delivered rather than the patient's PS. Hence, widely believed dogmas concerning the tolerance of critical structures to conventionally fractionated doses, such as the dose-volume effect, total dose, and time (latency) dependency, has to be re-evaluated for hypofractionated radiation therapy. As well there is data suggesting that the small stages I - II NSCLC are likely to benefit from hypofractionated regimens too. Hypofractionated stereotactic radiotherapy is a new technically complex approach to the treatment of early-stage nonsmall cell lung cancer. It is capable to deliver much higher doses to the cancer than is possible with standard techniques, and as a result, rates of tumour control are high and similar to what can be achieved by surgical resection. Refinements of technique and dose as well as randomized data are required before stereotactic radiotherapy can be endorsed as a standard of care for patients with inoperable peripherally located T1 non small cell lung cancer. A clear advantage of the very short hypofractionated palliative regimen is that it allows patients with a short expected survival time to spend more of their remaining time away from the hospital.
