introduction: colorectal cancer is the most common cancer of the alimentary system. in women, it is the second leading cause of mortality after breast cancer while in men, it is the third leading cause of death after lung and prostate carcinoma. prevalence is more in population older than 50 years and increases in older people. therefore, best treatment and prognosis is early diagnosis of disea...

oral cancer has emerged as a significant cause of global public health concern in both developing and developed nations. multiple socio-demographic and habit-related risk factors have been attributed to causing oral cancer. a diverse array of challenges exists in the global campaign to address the burden of oral cancer. such challenges have served as barriers to the early diagnosis and treatmen...

back ground and objective:oral cancer is primarily a disease of epithelial origin. the tongue is the most common site of oral cancer. the aim of this study was to determine the frequency of tongue cancer and signs, symptoms, clinical features, and site of lesions in addition to factors affected this cancer.  materials methods and:twenty eight medical records of patients who admitted for tongue...

background: ultrasound propagation velocity was measured experimentally in normal, fibroadenoma and ductal carcinoma breast tissues, in order to distinguish normal breast tissue from tumors. materials and methods: in quantitative measurements of ultrasound velocity, 403 breast tissue images were selected, comprising 130 normal breast tissue, 130 fibroadenoma, and 143 ductal carcinoma tumors. th...

introduction breast cancer is the second cause of mortality among women. early detection of it can enhance the chance of survival. screening systems such as mammography cannot perfectly differentiate between patients and healthy individuals. computer-aided diagnosis can help physicians make a more accurate diagnosis. materials and methods regarding the importance of separating normal and abnorm...

rhabdomyosarcomas are the most common soft tissue sarcoma in adult and children that accompany with skeletal muscle differentiation. skin metastasis of rhabdomyosarcomas is unusual and has only been sporadically reported in literature. in this paper we present a case of skin metastasis of rhabdomyosarcoma in an 8-year-old girl that has treated with chemotherapy.

results thirty-four patients were hyperglycemic and 127 non diabetic. sensitivity, specificity, positive predictive value and negative predictive value of fdg-pet/ct were 90%, 88%, 87% and 91% in non diabetic and 82%, 92%, 95% and 73% in hyperglycemic patients, respectively. overall, the accuracy was higher in non diabetic than hyperglycemic patients (89% vs. 85%). conclusions accuracy of fdg-p...

receptors and proteins are overexpressed in many human cancer cell membranes rather than normal tissues and are considered as the main molecular targets. specific tumor- targeting molecules which have high affinity for these receptors can be valuable tools as carrier molecules for targeted cancer therapy and imaging. pharmacokinetics and bioavailability of diagnostic and therapeutic agents are ...

background: to determine a cut-off point of tpsa and psad to prevent unnecessary invasive cancer-diagnosing tests in the community. methods: this study was performed on 688 consecutive patients referred to our center due to prostatism, suspicious lesions on digital rectal examination and/or elevated serum psa levels. all patients underwent transrectal ultrasound guided biopsies and obtained psa...
