Both tumors and patients are complex and models that determine survival and toxicity of radiotherapy or any other treatment ideally must take into account this variability as well as its dynamic state. The genetic features of the tumor and the host, and increasingly also the epi-genetic and proteomic characteristics, are being unraveled. Multiple techniques, including histological examination, blood sampling, measurement of circulating tumor cells (CTCs), and functional and molecular imaging, can be used for this purpose...

With the improvement of external radiotherapy delivery accuracy, such as intensity-modulated and stereotactic body radiation therapy, radiation oncology has recently entered in the era of precision medicine. Despite these precise irradiation modalities, lung cancers remain one of the most aggressive human cancers worldwide, possibly because of diverse genotypic alterations that drive and maintain lung tumorigenesis. It has been long recognized that imaging could aid in the diagnosis, tumor delineation, and monitoring of lung cancer...

Background: Women infected with Human Immune Deficiency Virus (HIV) are assumed to be at higher risk of developing Cervical Cancer (CC). This is due to a rapid progression of pre-invasive to invasive lesions. However, evidences suggest, due to the availability of antiretroviral therapy (ART) and care services; an improved survival and treatment outcome of CC patients (CCPs) with HIV infection is expected. Objective: The aim of this study is to examine the clinical characteristics and survival of of CCPs registered at the radiotherapy center of Tikur Anbessa Specialized Hospital (TASH), Addis Ababa University, Ethiopia...

As the use of breast reconstruction and postmastectomy radiotherapy (PMRT) has increased over the past decade, the typical approach to integrating radiotherapy with breast reconstruction has provoked intense controversy in the management of breast cancer. PMRT can lead to an increased frequency of complications in the reconstructed breast. Conversely, the reconstructed breast can increase the complexity of radiotherapy delivery. How to minimise the frequency of complications without compromising oncological or cosmetic outcomes of the reconstructed breast is an important shared multidisciplinary goal for oncologists and their patients...

Oral mucositis (OM) is an inflammatory response of mucosal epithelium to the cytotoxic effects of chemotherapy and radiotherapy causing severe oral pain and ulceration, which may complicate the management of cancer. The Mucositis Prevention Guideline Development Group has developed an international guideline for the prevention of mucositis in children receiving treatment for cancer or undergoing haematopoietic stem cell transplantation. Evidence-based preventative strategies include cryotherapy, low-level light therapy and keratinocyte growth factor...

Carcinogenesis has a multifactorial etiology, and the underlying molecular pathogenesis is still not entirely understood, especially for eye cancers. Primary malignant intraocular neoplasms are relatively rare, but delayed detection and inappropriate management contribute to poor outcomes. Conventional treatment, such as orbital exenteration, chemotherapy, or radiotherapy, alone results in high mortality for many of these malignancies. Recent sequential multimodal therapy with a combination of high-dose chemotherapy, followed by appropriate surgery, radiotherapy, and additional adjuvant chemotherapy has helped dramatically improve management...
