The authors report on a case of concurrent herpes simplex encephalitis (HSE) and malignant glioma. The co-occurrence of HSE and malignant glioma is very rare, but it can occur during glioma treatment. Both radiotherapy and chemoradiation with temozolomide can induce viral reactivation, leading to HSE relapse. Careful observation for HSE is necessary when administering chemoradiation to patients...
Background: Chemo-radiotherapy-induced oral mucositis represents a therapeutic challenge frequently encountered in cancer patients. This side effect causes significant morbidity and may delay or interruption of treatment plan, cyclo-oxygenase 2 (COX2) is an inducible enzyme primarily expressed in inflamed and tumoral tissues. COX-2 inhibitors have shown promise to reduce chemoradiation induce t...
Background: Esophageal carcinoma is among the first ten common malignancies worldwide, with a high prevalence in Iran. Previously, surgery or radiotherapy were the only modalities of therapy however, due to unsatisfactory outcomes, other therapeutic approaches such as chemoradiation are now under assessment as the first line treatment. Preliminary results have shown reduced local recurrence and...
Telomerase, an enzyme associated with cellular immortality, is expressed by most malignant cells and is inactive in most normal somatic cells, with the exception of proliferative stem cells, germ cells and activated lymphocytes. Measuring telomerase activity clinically may provide useful diagnostic and prognostic information of cancer. The purpose of this study was to investigate the change in ...
BACKGROUND AND PURPOSE The aim was to verify whether preoperative conventionally fractionated chemoradiation offers an advantage in sphincter preservation in comparison with preoperative short-term irradiation. PATIENTS AND METHODS Patients with resectable T3-4 rectal carcinoma without sphincters' infiltration and with a lesion accessible to digital rectal examination were randomised into: pr...
Pancreatic cancer, the fourth most common cause of cancer deaths, has a five-year survival rate of 5% or less. Surgical removal of the tumor may improve survival, but survival remains poor even in optimally resected patients. The best adjuvant therapy for patients with resected pancreatic cancer is not clear. Surgical resection followed by chemoradiation and maintenance chemotherapy has been co...
BACKGROUND Patients with stage III non-small-cell lung cancer (NSCLC) and limited disease small-cell lung cancer are excluded from concurrent chemoradiation mostly on the basis of comorbidity and age. The purpose of this prospective study was to get insight in what proportion of patients with locally advanced lung cancer would be suitable for concurrent chemoradiation. PATIENTS AND METHODS Fr...
BACKGROUND The implementation of preoperative chemoradiation combined with total mesorectal excision has reduced local recurrence rates in rectal cancer. However, the use of both types of treatment in upper rectal cancer is controversial. OBJECTIVE The purpose of this work was to assess oncological results after radical resection of upper rectal cancers compared with sigmoid, middle, and lowe...
BACKGROUND Standard treatment of advanced squamous cell carcinoma of the head and neck (SCCHN) is concurrent chemoradiation. Erlotinib is an oral tyrosine kinase inhibitor of epidermal growth factor receptor, which has shown activity in SCCHN. Phase I study aims to determine the maximum tolerated dose and dose-limiting toxicity (DLT) of adding erlotinib to chemoradiation therapy in patients wit...
