introductio: hematopoietic stem cell transplants (hsct) are considered as treatment options for patients with solid tumors. transplant numbers have changed significantly over the last decade. we have done autologous and allogeneic hsct for treatment of solid tumor patients in our center. methods: in order to show the transplant effect on solid tumor treatment, we collected data from 71 patients...

introduction bnct is an effective method to destroy brain tumoral cells while sparing the healthy tissues. the recommended flux for epithermal neutrons is 109 n/cm2s, which has the most effectiveness on deep-seated tumors. in this paper, it is indicated that using d-t neutron source and optimizing of beam shaping assembly (bsa) leads to treating brain tumors in a reasonable time where all iaea ...

introduction: during radiotherapy, high accuracy in the dose delivery is required because there is a strong  relationship between the absorbed dose, local tumor control and particularly the normal tissue damage. in  many institutions, in vivo dosimetry using diodes is performed to check the actual dose delivered. in general,  the uncertainty in the dose delivered should fall within  ± 5% of the...

a seven year-old boy with several painless masses on the ribs and shoulder was referred to our hospital. the masses were so prominent that they prevented the child’s sleep. since the patient had been ridiculed by his friends due to the rib prominences, he had refused to attend school. after clinical and radiological evaluations, the masses were diagnosed as hereditary multiple exostoses of the ...

malignant mixed germ cell tumors,though rare overall, are the most common type of malignant ovarian neoplasms in young and adolescent girls. these tumors are rapidly growing and can metastasize. we report a case of 13-yr-old girl who presented at shkm gmc, nalhar, mewat, haryana, india in december 2013 with huge abdominal lump of a malignant mixed germ cell tumor comprising both immature terato...

introduction: gastrointestinal stromal tumors (gists) are the most common mesenchymal neoplasms of the gastrointestinal tract. gist has been shown to over-express c-kit (cd117), the receptor tyrosine kinase. imatinib (sti571 or glivec) is a new type of tyrosine kinase inhibitor that selectively inhibits various tyrosine kinases and has been successfully used to treat gist. in this study we have...

the term calcifying odontogenic cyst (coc) was first introduced by gorlin in 1962. coc occurs mainly as an intra-osseous lesion in mandible or maxilla but the peripheral variation of coc has also been reported. the confusion about coc nature as cyst or tumor has not been resolved and a vast diversity has been shown in clinicopathologic aspects of coc. the purpose of this study was the review an...

background: esophageal squamous cell carcinoma (escc) is one of the lethal cancers with a high incidence rate in asia. many genes including cyclin d1 and p16 play important role in its carcinogenesis. we aimed to analyze the expressions of cyclin d1 and p16 with the various clinicopathological characteristics of escc.   method: we examined 30 biopsy samples of escc for cyclin d1 and p16 protein...

background: salivary gland tumors are relatively uncommon and they consist of 3-10% of head and neck neoplasms. most of studies have shown geographic variation in the incidence and histopathologic types of salivary gland neoplasms. the aim of this study was to evaluate the salivary gland tumors in isfahan for 10 years duration. materials and methods: in this epidemiological study, 229 medical r...

Background: Some studies have reported a correlation between adnexal tumors and human papilloma virus (HPV) infection. We performed this study to determine the incidence of HPV infection in adnexal tumor samples to further clarify any potential link between HPV and the pathogenesis of adnexal tumors.Methods: A total of 65 formalin-fixed, paraff...
