- چکیده:
- چکیده انگلیسی: The standard therapy for thyroid cancer is total or near total thyroidectomy, followed by the administration of radioactive iodine for remnant ablation or residual disease. Patients with radioiodine therapy are predisposed to second malignant neoplasms in organs such as central nervous system (CNS), breast, prostate, kidney, bone marrow, salivary gland, and digestive tract. Exposure to carcinogen including occupational and therapy related hazard, aging and genetic susceptibility are other causes of second primary cancers. The second primary malignancies are not uncommon and, nowadays, the prevalence of it is mildly increasing due to the increasing survival of cancer patients and advances in early diagnosis and therapeutic modalities. Here, we present a fifty-one-year-old man with papillary thyroid carcinoma (PTC), who developed chronic lymphocytic leukemia (CLL), renal cell carcinoma (RCC), and basal cell carcinoma (BCC) in 15-20 years after radioactive iodine therapy. Second primary tumors are increasing and environmental, genetic susceptibility and increase in survival of cancer patients are the major risk factors.

- چکیده:
- چکیده انگلیسی: Background: Prostate specific antigen (PSA) has been used as a screening test for the early detection of prostate cancer (PC) for many years. Although the introduction of PSA test led to a considerable increase in reported prostate cancer cases, there is still some controversy over the sensitivity and specificity of this marker in distinguishing PC patients from those with benign prostate hyperplasia (BPH), the most common benign prostate condition.
Objective: An attempt is made to elucidate if the plasma level of Interleukin 8 (IL-8) could be used effectively as a marker for the detection of prostate cancer.
Methods: Plasma levels of IL-8 and PSA were measured in two groups of 40 BPH and PC patients using enzyme-linked immunosorbent (ELISA) and radioimmunoassay (RIA) techniques, respectively. In addition IL-8 levels in PC3 and DU145 cell line supernatants were measured by ELISA technique.
Results: The concentration of IL-8 in the plasma of PC patients was not significantly higher than the BPH subjects. Although, a correlation between plasma IL-8 concentration and the Gleason score of PC patients was found, no indicated correlation was detected between the concentration of IL-8 or PSA and age of the patients in both groups. DU145 and PC3 cell lines produced and secreted IL-8 in the media.
Conclusion: Data of this investigation collectively conclude no correlation between IL-8 concentration in PC and BPH patients.- انتشار مقاله: 16-05-1395

- چکیده:
- چکیده انگلیسی: Background: Triple-negative breast cancer (TNBC) is an aggressive type of breast cancer (BC), and its diagnosis is associated with negative expression of hormone receptors and HER2/neu. It consists of 10-20% of all BCs diagnosed. Methods and materials: This study focuses on three groups with different pathology: group one showed complete triple-negative HER2 expression with IHC of BC; groups two and three included patients with ER-, PR-, and HER21+, and ER-, PR-, and HER22+ with a negative FISH test. These three groups were compared from the point of prognosis, which consisted of tumor size, patients’ age, lymphatic, vascular and perineural invasion, organ metastasis, number of lymph nodes involvement, and the survival rate. Results: A total of 459 TNBC patients were enrolled, of which 268 were placed in the HER20 group, 146 in the HER21+ group, and 45 in the HER22+ group. Distant metastasis and recurrence rate were more common in HER20 patients, but bone metastasis was more common in patients with low HER2 expression. All patients with HER20 had a smaller tumor size at the time of BC diagnosis in comparison to patients in the low HER2 expression group. Patients with HER22+ had less lymphatic and vascular invasion as well as axillary lymph nodes involvement, but larger tumor size at presentation, resulting in a lower rate of recurrence and higher overall survival. Conclusion: The findings revealed that patients with HER22+ had better outcome in comparison to the patients with HER20 and HER21+. Furthermore, the results showed that many patients with HER22+ expression were not basal-like and had good prognosis amongst TNBC patients.

- چکیده:
- چکیده انگلیسی: Background: ACEI (Angiotensin Converting Enzyme Inhibitors) inhibits tumor growth and development. Different mechanisms have been proposed for this matter, including the inhibition of enzymes that are involved in extracellular matrix degradation, matrix metalloproteinase (MMP) and etc. The present study was designed with the aim to investigate the effects of low dose ACEI on the Quality of Life (QoL) of non-hospitalized gastric cancer patients with cachexia.Materials and Methods: This study was a single-blinded randomized controlled clinical trial conducted in clinics affiliated with Shiraz University of Medical Sciences (SUMS). All participants were patients with gastric cancer in cancer cachexia step aged 40-80 years old who had referred to our clinics from October 2013 to April 2014. In the intervention group, patients were assigned to receive ACEI (Captopril) and the placebo group served as control and received placebo during the same time course. They were asked questions in order to fill out QLQ-C30 (Persian Version) questionnaire 3 times; baseline, 1 and 2 months after their first visit. Results: The mean age of patients was 60.55 ± 12.07 (range 31-80) years and the mean BMI of the patients was 17.21 ± 2.31. In the ACEI group, physical functioning and fatigue score changes were significant 1 and 2 months after treatment. The mean of fatigue score decreased significantly in the placebo group. Overall, global health status scores significantly increased in both groups, but other items of QoL did not change significantly. Conclusion: Overall, our results showed that Captopril does not have a significant positive effect on QoL of patients with cancer cachexia.
