objective(s): the present study was conducted to examine whether the standardized uptake value (suv) may be affected by the spatial position of a lesion in the radial direction on positron emission tomography (pet) images, obtained via two methods based on time-of-flight (tof) reconstruction and point spread function (psf). methods: a cylinder phantom with the sphere (30mm diameter), located in...
conclusions prognosis of this type of tumor, apart from its size and differentiation level, depends on infiltration in tumor-surrounding tissue, perineural and perivascular spread. therefore, it is always necessary to analyze the removed skin especially on margins. introduction squamous cell carcinoma is the most common type of lip and oral cavity cancers. in majority of cases it follows quite ...
Background: Despite the long-term survival in papillary thyroid cancer (PTC), cervical lymph node metastasis is the most important factor in regional recurrence of the disease. The aim of the present study was to find clinical risk factors for microscopic metastasis to the lymph nodes, without involvement of the neck lymph nodes. Methods: medical records of 115 PTC patients who underwent tot...
the relationship between imp3 expression in colorectal adenocarcinoma and clinicopathologic findings
conclusions imp3 immunoreactivity was associated with poor differentiation of tumor yet not associated with tumor size depth of invasion or lymph node involvement. results immunoreactivity pattern of imp3 was cytoplasmic in different clinicopathologic findings. among different clinicopathologic findings, we found a statistical relationship between tumor differentiation and imp3 (p = 0.047); so ...
Background and purpose: Gastric carcinoma is one of the most common malignancies and its early diagnosis can be effective in the treatment method and the rate of the patients’ survival. Ïn the past recent years, many genes have been identified which may have relationship with the prognosis of this disease and the patient’s survival.
