conclusions most patients are referred for restaging and demonstrate evidence of regional or distant metastasis with significant value for further treatment planning. providing insurance coverage and familiarizing referring physicians about appropriate indications of this relatively new diagnostic modality will be to the best interest of head and neck cancer patients in long term. methods we re...

Background: Invasive ductal carcinoma is the most common type of breast cancer in Iran. Impaired immune responses occur frequently in cancer patients, but the mechanisms of the induced immune defects remain poorly understood. It is believed that infiltrated immune cells, especially macrophages, may provide help for tumor cell growth and metastasis.   Objective: To analyze the status of tumor as...

Herein, we review the current findings of how a variety of accessory cells could participate in shaping the tumor microenvironment and supporting the mechanisms by which cancer cells undertake the epithelial-mesenchymal transition (EMT). EMT, a complex of phenotypic changes, promotes cancer cell invasion and creates resistance to chemotherapies. Among the accessory cells present in the EMT, imm...

background: to explore a possible rela!onship among blood groups and the prognosis of breast cancer, this case- control study was carried out in arak city, arak province, iran. materials and methods: one hundred and thirty four pa!ents with breast cancer were inves!gated. abo blood groups were obtained from medical records. mul!variate analyses were performed, including size of tumor, axillary ...

the aim of this study was assessing the adjuvant therapy of exercise on cytokines balance in mice with breast cancer tumor. twenty female balb/c mice were randomly assigned to experimental and control groups. after orientation in the environment, estrogen-receptor dependent breast cancer cells (mc4-l2) were injected to them and experimental group performed endurance training 5 day in week for 6...

Ovarian cancer is the most lethal gynecologic malignancy. The surface epithelial tumor is the most common type of ovarian cancer. Among these, the mucinous tumors account for 10-15% of ovarian tumors. Mucinous ovarian tumors are among the most difficult ovarian neoplasms for surgical pathologists to interpret. Mucinous tumors sometimes coexist with other surface epithelial tumors. Therefore, ma...

Background: Tumor lysis syndrome caused by widespread tumor cell damage may lead to electrolyte imbalances and express as metabolic disturbance causing clinical abnormalities. Patients and Methods: All patients younger than 16 years with documented malignancy candidate for chemotherapy, in Hamedan province of Iran were enrolled. Results: Out of 69 cancer patients the laboratory form of tumor ...

objective: e-cadherin is widely down-regulated and tightly associated with tumor invasion and metastasis in multiple human cancer types. recent studies have shown that aberrant methylation of the e-cadherin gene promoter contributes to its silencing. however, information regarding epigenetic inactivation of e-cadherin in colorectal cancer is insufficient. herein, we correlate association of the...

Background: Despite recent advances in diagnosis and treatment, breast cancer remains a leading cause of death in women worldwide. Long non-coding RNAs are a new class of RNA molecules that have been shown to participate in tumorigenesis. The aim of this study was to investigate the expression of lncUSMycN in tumor samples and to evaluate its potential role in the breast cancer cell line. Metho...
