From December 2000 until 2010, the researchers at Royan Institute conducted a wide range of investigations on ovarian tissue cryopreservation with the intent to provide fertility preservation to cancer patients that were considered to be candidates for these services. In 2010, Royan Institute established the Royan Human Ovarian Tissue Bank as a subgroup of the Embryology Department. Since its i...

objective(s): prostate cancer is the world’s leading cause of cancer and the second cause of cancer-related death in men after lung cancer. differentiation of prostate adenocarcinoma from benign prostate lesions and hyperplasia sometimes cannot be done on the basis of morphologic findings. considering the fact that in the prostate adenocarcinoma there is no basal cell layer, basal cell markers ...

The long non-coding RNA (lncRNA) metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) has been recently shown to be dysregulated in several cancers. However, the mechanisms underlying the role of MALAT1 in breast cancer remain unclear. Herein, we showed that MALAT1 was aberrantly increased in breast cancer tissues and cells. MALAT1-siRNA inhibited breast cancer cell proliferation and...

Background Breast cancer is the most common cancer in women worldwide. Cancer-secreted exosomes have recently been recognized as important mediators of intercellular communication. The aim of this study was to determine the role of exosomal long noncoding RNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) in breast cancer progression. Materials and methods Breast cancer speci...

Invasive lobular carcinoma of the breast has similar patterns of metastatic disease when compared to invasive ductal carcinoma; however, lobular carcinoma metastasizes to unusual sites more frequently. We present a 65-year-old female with a history of invasive lobular breast carcinoma (T3N3M0) treated with modified radical mastectomy and aromatase-inhibitor therapy who underwent a surveillance ...

Occult breast cancer (OBC) is a type of breast cancer without any symptoms in the breast (no primary cancer lesion is found in either breast on a physical examination or imaging examination such as ultrasound and mammography). The incidence of OBC is rare in females, whereas in males, there are few cases of breast cancer, and the rate of OBC is very low. This is the first time report a case of ...

Although the majority of forequarter amputations are performed for high-grade bone and soft tissue sarcomas or extensive osteomyelitis of the upper extremity, this radical operation may also be indicated for the curative treatment of recurrent breast cancer and for the palliation of locally advanced breast cancer. We report a male patient with metastatic breast adenocarcinoma who underwent simu...

Breast metastasis from extra-mammary malignancy is not common. According to the literature, an incidence of 0.4-1.3% has been reported. We present three cases of metastasis to the breast from two pulmonary adenocarcinoma and one lung squamous carcinoma diagnosed concomitantly or metachronous with the primary tumor. Two pulmonary adenocarcinomas (a 43-year-old female and a 45-year old female) pr...

AIM Breast cancer (BC) is one of the most common forms of cancer amongst females. Early diagnosis, prognosis and therapy plays crucial role in the survival of patients with breast cancer. The study was aimed on identification of potential markers for early BC diagnostics by means of genome-wide comparative analysis of gene expression in cancer and normal tissue of breast. METHODS The analysis...

BACKGROUND DNA methylation is an important mechanism for gene silencing and has already been described for several genes in breast cancer. A previous immunohistochemistry study demonstrated a decrease of K(v)1.3 potassium channel expression in breast adenocarcinoma compared to normal breast tissue. METHODS Methyl-specific PCR (MSP), immunohistochemistry and RNA extraction were performed on br...
