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...
Recently, mutations of the transforming growth factor-b receptor type I gene have been reported to occur at high frequency in breast cancer metastases, with all mutations being an identical C to A transversion at nucleotide 1160 of the gene (T. Chen et al., Cancer Res., 58: 4805–4810, 1998). This mutation would result in a serine to tyrosine substitution at codon 387 (S387Y) and would reportedl...

Primary rectal adenocarcinoma metastatic to the breast is an exceedingly rare event. Its management differs from that of primary breast cancer, as illustrated by this case. A 63-year-old woman presented with a breast lump 30 months after abdominoperineal resection for rectal adenocarcinoma, stage T₃N₁M₀ (stage III), followed by standard postoperative radiochemotherapy. The patient underwent a m...
Neurotensin receptor 1 (NTS1) is overexpressed on a variety of cancer entities; for example, prostate cancer, ductal pancreatic adenocarcinoma, and breast cancer. Therefore, it represents an interesting target for the diagnosis of these cancers types by positron emission tomography (PET) [...].
Metastasis to breast from nonmammary malignancy is only about 1.3-2.7%. A few cases of squamous cell carcinoma of esophagus and adenocarcinoma of stomach metastasizing to breast have been reported, but this is probably the first report of breast metastasis from esophagogastric junction (EGJ) cancer in the English literature. Herein we report a case of a 32-year-old patient diagnosed as adenocar...
Design, synthesis, and conjugation of mesoporous silica nanoparticles (MSNs) with biomolecules is a matter of growing interest to enhance selective uptake of contrast agents like gadolinium (Gd3+) by cancer cells. Here, by targeting xc-cystine/glutamate antiporter system in breast cancer cells, conjugation of MSN-Gd3+ with cysteine is used to enhance cancer cellular uptake of Gd3+. Reactions de...
We report a case of adenocarcinoma affecting the chin of a 48-year-old man. The tumor showed signs of apocrine differentiation and had infiltrated the muscle. The patient had no history or clinical evidence of breast cancer. We made a diagnosis of cutaneous apocrine adenocarcinoma. Apocrine adenocarcinoma rarely arises in areas with scarce apocrine glands. We reviewed the literature on apocrine...
Epidemiological studies have provided convincing evidence that obesity increases the risk for cancers of the oesophagus (adenocarcinoma), colon, pancreas, breast (post-menopausal), endometrium and kidney. The magnitude of the increase in risk varies between cancer sites. For an increase in BMI of 10 kg/m2 relative risks are approximately 2.3 for adenocarcinoma of the oesophagus, 1.5 for colon c...
background: exposure to endogenous hormones such as estrogen is known as a lifetime breast cancer (bc) risk factor. polymorphisms in genes that are involved in the steroidogenic process, such as cytochrome p450c17alpha ( cyp17) , affect individuals’ susceptibility to bc. in iran, the highest incident of bc is among young women. this study aimed to find prevalence of single nucleotide polymorphi...
