Radiation therapy is one of the most important methods for the treatment of malignant tumors. However, in radiotherapy for thoracic tumors such as breast cancer, lung cancer, esophageal cancer, and mediastinal lymphoma, the heart, located in the mediastinum, is inevitably affected by the irradiation, leading to pericardial disease, myocardial fibrosis, coronary artery disease, valvular lesions, and cardiac conduction system injury, which are considered radiation-induced heart diseases. Delayed cardiac injury especially myocardial fibrosis is more prominent, and its incidence is as high as 20–80%...

Cancer survivors after radiotherapy may suffer a variety of bone‑related adverse side effects, including radioactive osteoporosis and fractures. Localized irradiation is a common treatment modality for malignancies. Recently, a series of reactions and injuries called indirect effects (remote changes in bone when other parts of the body are irradiated) have been reported on the indirect irradiated area of bone tissue after radiotherapy. To address this issue, we developed a rat localized irradiation model...

Sarcomas are malignant tumors that are characterized by a wide diversity of subtypes with various cytogenetic profiles. Despite major treatment breakthroughs, standard treatment modalities combining chemotherapy, radiotherapy, and surgery failed to improve overall survival. Therefore, high expectations are foreseen with immunotherapy upon its maturation and better understanding of its mechanism of action. This paper presents a targeted review of the published data and ongoing clinical trials in immunotherapies of sarcomas, mainly adoptive cell therapies, cancer vaccines and immune checkpoint inhibitors...

BACKGROUND: Extranodal follicular dendritic cell sarcoma (FDCS) is a very rare malignancy with a variable clinical course. It is often not considered and has the potential to result in a misdiagnosis of other common sarcomas or sarcomatoid carcinomas. This is particularly true with the preoperative biopsy specimen, in which the tissue sample is often small. CASE PRESENTATION: A case of FDCS in a 63-year-old woman, arising in the urinary bladder, a previously unreported site, is described...

Breast cancers are the most common cancers in women. However, breast cancer occurring in a pectoralis major myocutaneous flap is extremely rare. This article describes a case of breast cancer occurring in such a flap used for reconstruction of the tongue in a 72-year-old woman. Follow-up computed tomogram depicted a slowly growing mass in the flap. Thirty-nine months postoperatively, a fine-needle aspiration biopsy specimen taken from the lesion suggested glandular carcinoma. The patient was diagnosed with breast cancer in the neck area of the flap and tumor excision was performed...

Treatment of cancer patients involves a multidisciplinary approach including surgery, radiotherapy, and chemotherapy. Traditionally, patients with metastatic disease are treated with combination chemotherapies or targeted agents. These cytotoxic agents have good response rates and achieve palliation; however, complete responses are rarely seen. The field of cancer immunology has made rapid advances in the past 20 years. Recently, a number of agents and vaccines, which modulate the immune system to allow it to detect and target cancer cells, are being developed...

Chronic glomerular and tubular nephrotoxicity is reported in 20-50% and 20-25%, respectively, of children and adolescents treated with ifosfamide and 60-80% and 10-30%, respectively, of those given cisplatin. Up to 20% of children display evidence of chronic glomerular damage after unilateral nephrectomy for a renal tumour. Overall, childhood cancer survivors have a ninefold higher risk of developing renal failure compared with their siblings. Such chronic nephrotoxicity may have multiple causes, including chemotherapy, radiotherapy exposure to kidneys, renal surgery, supportive care drugs and tumour-related factors...

OBJECTIVES: Kallikreins are serine proteases over expressed in many malignancies. In this study, we measure changes in serum kallikrein (KLKs) levels during intensity-modulated radiotherapy (IMRT) in prostate cancer patients, and find potential correlations between serum kallikrein level and normal tissues toxicity during radiation. METHODS: Forty-nine patients with prostate cancer were recruited as follows: group 1, definitive standard fractionation IMRT (78Gy in 39 fractions, n=15); group 2, definitive hypofractionated IMRT (60Gy in 20 fractions, n=15); and group 3, IMRT postprostatectomy (66Gy in 33 fractions, n=19)...

Male breast cancer (MaBC) is a rare disease, accounting for less than 1% of malignancies in men. For this reason, literature data on its clinicopathological characteristics are very heterogeneous and treatment strategies have mostly been extrapolated from the female counterpart. However, immunohistochemical peculiarities of MaBC have recently emerged, defining it as a distinct entity from female breast cancer (FBC), thus requiring a tailored clinical approach. MaBC appears to be more often hormone receptor positive than FBC, while data on HER2 status still remain inconclusive, indicating a possible higher incidence of HER2 alterations...

Oesophageal cancer is a relatively uncommon malignancy, but with poor prognosis. Despite several treatment options that are available, the 5-year survival rates rarely exceed 40%. This review discusses the main challenges of oesophageal cancer, the available treatment options, and the most effective treatment in terms of overall survival. The outcomes of clinical trials show that neo-adjuvant chemo-radiotherapy using cisplatin and 5-fluorouracil followed by oesophagectomy results in the greatest survival. However, the optimal chemotherapy and radiotherapy schedule remains unclear...

Genital bleeding is the most common and serious complication in gynecologic malignancy. Different techniques are available for the control of severe bleeding, but standard treatment strategies have not been determined. Herein we report on the successful use of the balloon technique in two cases of genital bleeding in uterine neoplasm. The first case was of advanced cervical cancer with massive genital bleeding during radiotherapy. A metreurynter (mini-metro) was inserted into the vagina and hemostasis was indirectly achieved in the vaginal hematoma...

BACKGROUND: Astrocytoma, a common and highly malignant type of brain tumor, is associated with poor overall survival despite advances in surgical treatment, radiotherapy, and chemotherapy. The nuclear transcription factor Fli-1 has been shown to increase cellular proliferation and tumorigenesis in many types of cancer; however, previous reports have not described a correlation between clinical outcomes and Fli-1 in astrocytoma patients. The present study aimed to elucidate the clinical role of Fli-1 in astrocytoma...

Non-small cell lung cancer (NSCLC) remains a major health problem that patients suffer from around the world. The epithelial to mesenchymal transition (EMT) has attractive roles in increasing malignant potential and reducing sensitivity to conventional therapeutics in NSCLC cells. Meanwhile, it is now evident that non-coding RNAs (ncRNAs), primarily microRNAs and long non-coding RNAs contribute to tumorigenesis partially via regulating EMT. This article briefly summarizes current researches about EMT-related ncRNAs in NSCLC and discusses their crucial roles in the complex regulatory network...

Conventional anticancer therapies such as radiotherapy and chemotherapies are associated with oxidative stress generating reactive oxygen species (ROS) and reactive aldehydes like 4-hydroxynonenal in cancer cells that govern them to die. The main mechanism activated due to exposure of the cell to these reactive species is the Nrf2-Keap1 pathway. Although Nrf2 was firstly perceived as a tumor suppressor that inhibits tumor initiation and cancer metastasis, more recent data reveal its role also as a pro-oncogenic factor...

Esophageal squamous cancer is one of the most fatal malignancies and often suffer recurrence after radiotherapy. Downregulation of miRNA-200c is associated with radiotolerance. We aim to investigate the role of miRNA-200c in radiosensitivity and develop a systemic treatment strategy for esophageal squamous cancer. Overexpression of miRNA-200c by transfection was determined by RT-PCR. Radiosensitizing effect of miRNA-200c on esophageal squamous cancer cells was determined by clonogenic assay and xenograft model...
