PURPOSE Due to the increased prevalence of thyroid cancer, it has been frequently detected in breast cancer patients recently. The aim of this study was to evaluate the clinicopathologic characteristics of thyroid cancer in breast cancer patients with respect to prognosis and treatment. METHODS From August 1998 to September 2012, 101 breast cancer patients were diagnosed with thyroid cancer (...

Background: The induction of cancer appears to be the most important effect of low-dose ionizing radiation to occur in an exposed population. In developing countries 94% of human radiation is from natural sources. In Iran some high altitude regions such as, Chaharmahal & Bakhtiari has high levels of the natural background radiation (higher than the worldwide average). Therefore, investigation o...

background: interleukin-19, a member of the interleukin-10 family of cytokines, contributes to breast cancer pathogenesis. high interleukin-19 expression in breast tumor tissues is associated with poor clinical outcome. this study aimed to assess the changes in serum level of interleukin-19 in breast cancer patients in comparison with normal women and its association with the clinicopathologica...

BACKGROUND Although many reports indicated an association between thyroid diseases and breast cancer, such an association still remains controversial. The present study was aimed to clarify the association of thyroid diseases with the breast cancer incidence. In the patients with benign and malignant thyroid tumor or tumor-like disorders, the incidence of other malignancies was surveyed, and th...

OBJECTIVE To assess thyroid dysfunction in head and neck cancer patients who have received external beam radiotherapy according to radiotherapy fields and dose, tumor site and other local or systemic treatments retrospectively and prospectively and propose a follow-up schedule. MATERIAL AND METHODS A total of 378 patients was classified into two groups. Group I (n = 345) consisted of surgical...

BACKGROUND There are no consistent agreements on whether radiotherapy after breast-conserving surgery (BCS) could provide local control and survival benefit for older patients with early breast cancer or breast ductal carcinoma in situ (DCIS). The present study aimed to evaluate the efficacy of radiotherapy after BCS in older patients with early breast cancer or DCIS. RESULTS Radiotherapy cou...

BACKGROUND Multiple studies have examined the incidence of secondary primary malignancies (SPMs) in gastric cancer patients in Europe and Asia. This retrospective review was conducted to analyze risk of SPM in patients with gastric cancer diagnosed in the United States. METHODS We included adult patients diagnosed with gastric cancer from the surveillance, epidemiology, and end result (SEER) ...
