to determine the addition of value of neoadjuvant, concurrent and adjuvant chemotherapy to radiation in the treatment of nasopharyngeal carcinoma with regard to the overall survival (os) and disease free survival (dfs) within a six year period in tehran cancer institute. files of all patients with nasopharyngeal carcinoma treated by radiotherapy with or without concurrent chemotherapy in a cura...
background : the present study aimed to report the characteristics and treatment outcomes of five patients with nasopharyngeal adenoid cystic carcinoma and a literature review. methods : between 2000 and 2009, five consecutive patients (4 men, 1 woman) were diagnosed with nasopharyngeal adenoid cystic carcinoma and treated at our institution. three patients had stage iva (t4n0m0) and two patien...
Background: Local recurrence in Nasopharyngeal Carcinoma (NPC) presents is a major challenge. Patients experience substantial morbidity as well as poor survival if no further treatment is offered. Residual or recurrent nasopharyngeal carcinoma is usually managed by chemotherapy, stereotactic radiosurgery, external beam radiation therapy (EBRT), interstitial, and intracavitary brachytherapy or s...
Nasopharyngeal cancer is unique among head and neck cancers. Despite definitive treatment, there is a high rate of recurrence, most commonly in the bone, lung or liver. Brain metastases and particularly, leptomeningeal carcinomatosis are extremely rare. We present a case of recurrent nasopharyngeal carcinoma with brain metastases and leptomeningeal carcinomatosis in the absence of local recurre...
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...
Introduction: Nasopharyngeal carcinoma (NPC) is commonly known as a radiosensitive tumor with the initial good response to radiation. Despite the improved outcome in loco regional control by the introduction of combining treatment, modern radiotherapy techniques and enhanced imaging studies, local recurrent after primary treatment with rate ranges from 15-58% in 5 years, stil...
Background: Colorectal cancer is the most common malignant gastrointestinal cancer and the fourth most common cancer throughout the world. Disease staging is performed to select the treatment method. In this interventional study we evaluated the effect of adjuvant chemotherapy on local recurrence, distant metastasis and three-year disease free survival in patients with stage 2 colorectal cancer...
background: this prospective study was conducted to evaluate and compare the efficacies of nasopharyngoscopy and ct scan in the diagnosis of local failure of external beam radiotherapy (ebrt) for nasopharyngeal carcinoma. methods: total 52 patients of histopathologically proven nasopharyngeal carcinoma treated with external beam radiotherapy (ebrt), were included in this study. for every patien...
BACKGROUND Detection of early recurrent nasopharyngeal carcinoma (NPC) is clinically challenging. Narrow-band imaging (NBI) is powerful in detecting early superficial lesions in the head and neck, although the utility of NBI in detecting nasopharyngeal cancer is still unknown. METHODS AND RESULTS We describe a case of a 51-year-old man with early recurrent NPC detected in subclinical stage by...
Nasopharyngeal cancer is a type of malignant tumor with a high rate of incidence. Cancer stem cells are regarded as one of the main causes for the formation and recurrence of nasopharyngeal cancer. CXC chemokine receptor type 4 (CXCR4) has been reported to perform an important role in cancer; however, the association between CXCR4 and nasopharyngeal cancer stem cells remains unclear. The presen...
