conclusions pet/ct can provide diagnosis and more accurate staging, location of tumor with its capability in providing the anatomical and physiological information synchronizes. therefore pet/ct plays an important role in oncology. objectives in this paper, we evaluate application of pet/ct for improve oncologic imaging. methods the papers were searched in pubmed and scopus databases with the r...

cancer of the stomach carries poor prognosis. surgery is the best treatment for gastric cancer. prediction of survival depends on the stage at the time of presentation. fluoroscopy, sonography, and computerized tomography are used for advanced gastric cancers staging, but they are not accurate enough to grade advanced gastric cancers. laparoscopic findings of lesions under direct vision, are ma...

ovarian cancer is the most lethal gynecological cancer and about 70% of the patients are advanced stagein the time of diagnosis. decision about management (surgical debulking versus neoadjuant chemotherapy) in ovarian cancer patients is dependent on initial staging by abdominopelvic mdct or mri, so, radiologist expertise on ovarian cancer staging is very important. involvement of mesenteric roo...

background: today the use of laparoscopy before laparotomy is an effective method for decision-making in patients with gastric adenocarcinoma. the reliance on ct scans for decision-making purposes is not only unhelpful, yet also misleading . nonetheless, indications for laparoscopy and its application are changing daily. the low quality of diagnostic tools and epidemiological situation in our c...

background: differentiation between the muscularis mucosae (mm) and muscularispropria (mp) of the bladder remains challenging. objective: to identify mm- and mp-specific antigens that could be of potential value for staging of urothelialcarcinomain a pilot study. method: the expression of 12 protein antigens in 11 human bladder specimens was examined. there were 5 post radical cystectomy specim...

breast cancer (bc) accounts for one of the major health problems around the world. since the diagnosis process can have great effect on therapy outcomes, we studied the biomarkers specific to breast tumors stage i based on examining different iranian patients. cases from different stages were examined to discover their highly expressed proteins. in addition, pathologic evaluations were performe...

rectal cancer is the second most common cancer in large intestine. the prevalence and the number of young patients diagnosed with rectal cancer have made it as one of the major health problems in the world. with regard to the improved access to and use of modern screening tools, a number of new cases are diagnosed each year. considering the location of the rectum and its adjacent organs, manage...

background beta catenin plays a key role in cancer tumorigenesis. however, its prognostic significance in patients with colorectal cancer (crc) remains controversial. it has been demonstrated that 90% of all tumors have a mutation in individual components of multiple oncogenes in wnt/β-catenin pathway. accumulation of nuclear β-catenin in cytoplasm leads to uncontrolled cell proliferation. thus...
