results there was no statistical difference between the 2 groups with respect to the recurrence rate (p > 0.05). although the recurrence interval was longer for the metformin group, this increase was not statistical significant (p > 0.05). furthermore, tumor recurrence had no correlation with sex or the grade of the tumors. conclusions according to our findings, it seems that metformin has no c...

calcifying epithelial odontogenic tumor (ceot) is an uncommon odontogenic tumor with well-known histopathological features and a challenging treatment plan. although some investigators advocate conservative approach as the treatment of choice, others believe in radical surgical excision to avoid recurrence or malignant transformation. the main objective of this case report is presenting an unus...

background: distinction between radiation necrosis and recurrence of intraparenchymal tumors is necessary to select the appropriate treatment, but it is often difficult based on imaging features alone. we developed an algorithm for analyzing magnetic resonance spectroscopy (mrs) findings and studied its accuracy in differentiation between radiation necrosis and tumor recurrence. m e t hod s :  ...

one of the unusual variant of ovarian tumor is sex cord stromal tumor with annular tubules (sctat). the recurrence in case of malignant ovarian sctat ranges from 3mo to 20yr. this report describes the case of recurrence of sctat in a 35yr old woman after 4yr of hysterectomy with bilateral salphingo-oopherectomy. microscopic examination revealed features of sctat. because of its unusual behavior...

introduction: 99mtc-mibi has been proposed for use as an imaging agent for various tumors, including breast cancer, lung cancer, lymphomas, melanomas and brain neoplastic lesions. brain tumors are very common and radiotherapy being major part of treatment following surgery. after radiotherapy, deteriorating clinical status can be due to either radiation necrosis or recurrent tumor. computed tom...

desmoid tumor of breast is a rare benign, locally aggressive tumor with a high recurrence rate. it has been associated with scar from previous breast surgery or trauma. especially in breast cancer patients with previous operation history, it may simulate recurrent breast cancer clinically and radiologically. we presented multimodality imaging findings (ultrasound, computed tomography, magnetic ...

background : meningiomas are common benign tumors of the central nervous system. patients with meningiomas achieve postoperative optimal functional recovery, but there is a probability of tumor recurrence months or years after surgical resection. this study aims to evaluate the prevalence of recurrent meningioma and the correlation between tumor recurrence and certain factors. materials and met...
