predictive factors of radiation-induced lung toxicity in lung cancer patients: a retrospective study
background: radiation-induced lung toxicity is an important dose-limiting toxicity in lung cancer radiotherapy, for which there are no generally accepted predictive factors. this study seeks to identify risk factors associated with the development of severe radiation-induced lung toxicity using clinical and dosimetric parameters. methods: we reviewed the medical records of 54 patients with hist...
Background: Epithelioid sarcoma is a malignant soft tissue tumor of uncertain histogenesis, categorized as a morphologically distinct neoplasm that characteristically affects the distal parts of the extremities in young adults. In fact, epithelioid sarcoma is the most common soft tissue sarcoma in the hand and wrist. Case report: This 32 year-old male presented with an inguinal swelling, for w...
Uterine sarcomas are rare female genital tract malignancies. Mullerian adenosarcoma is a biphasic malignant mesenchymal tumor comprising of benign glandular and (usually low grade) stromal component, both which integral neoplastic constituents the tumor.[1] This represents less than 8% uterine sarcomas. About 200 cases have been reported in literature so far [2] 22 case were from India. Adenosa...
giant cell glioblastoma is an extremely rare variant of glioblastoma (who grade iv) which is characterized by a predominance of bizarre, multinucleated giant cells. these tumors comprise of 0.8% of brain tumors and up to 5% of glioblastomas. in pediatric age group, these tumors are still uncommon with only around 53 published cases since 1952. here, we report a case of a 12-year old female pati...
Abstract Introduction: Breast cancer is the most common cancer among women. Even though mastectomy is known as a highly effective method to treat breast cancer, the percentage of patients with local recurrence is still high. Objective: To determine the incidence of local recurrence after mastectomy and breast preservation surgery. Materials and Methods: Patients with breast cancer that under...
Ovarian cancer, the most lethal gynecological cancer, related closely to tumor stage. High-grade ovarian cancer always results in a late diagnose and high recurrence, which reduce survival within five years. Until recently, curable therapy is still under research and anti-angiogenesis proves a promising way. Tumor-derived exosomes are essential in tumor migration and metastases such as angiogen...
breast cancer is the most common cause of cancer-related death in female, after lung cancer. angiogenesis is essential for tumor growth and metastasis; therefore, antiangiogenesis strategies for treatment of cancer are currently an issue of interest. the role of vascular endothelial growth factor that assumed to be most potent angiogenesis factor is ambiguous in breast cancer. this study descri...
Objective(s): Similar characteristics of molecular pathways between cellular reprogramming events and tumorigenesis have been accentuated in recent years. Reprogramming-related transcription factors, also known as Yamanaka factors (OCT4, SOX2, KLF4, and c-MYC), are also well-known oncogenes promoting cancer initiation, progression, and cellular transformation into cancer stem cells. Long non-co...
