The tumor microenvironment is critical for metastasis to occur. Subcutaneous xenografts of tumors in immunodeficient mice are usually encapsulated and rarely metastasize as opposed to orthotopic tumors which metastasize if the original tumor was metastatic. In the present report, we were able to reconstitute a metastatic tumor microenvironment by subcutaneously co-transplanting a human cervical...
PURPOSE We investigate the unknown tumor-killing activity of cytokine-induced killer (CIK) cells against autologous metastatic melanoma and the elusive subset of putative cancer stem cells (mCSC). EXPERIMENTAL DESIGN We developed a preclinical autologous model using same patient-generated CIK cells and tumor targets to consider the unique biology of each patient/tumor pairing. In primary tumo...
The matricellular protein osteopontin (OPN, Spp-1) is widely associated with cancer aggressiveness when produced by tumor cells, but its impact is uncertain when produced by leukocytes in the context of the tumor stroma. In a broad study using Spp1(-/-) mice along with gene silencing in tumor cells, we obtained evidence of distinct and common activities of OPN when produced by tumor or host cel...
A 65 years old male presented with abdominal pain (R.U.Q) and constipation, associated with weight loss and anorexia since 40 days prior to admission. Serum biochemical tests were normal. Colonoscopy showed hemorrhagic polypoid lesion in the cecum. Barium enema revealed filling defect in the cecum. Sonography revealed a target-shaped lesion (3cm×2.5cm) in upper segment of the right hepati...
For many cancer patients, removal of primary tumor is curative; however, if metastatic lesions exist and are not responsive to treatment, survival is limited. Although immunotherapy is actively being tested in animal models against primary tumors and experimental métastases(i.v. induced), very few studies have examined immunotherapy of spontaneous, established metastatic disease. The shortage ...
Tumors systemically initiate metastatic niches in distant target metastatic organs. These niches, composed of bone marrow–derived hematopoietic cells, provide permissive conditions for future metastases. However, the mechanisms by which these cells mediate outgrowth of metastatic tumor cells are not completely known. Using mouse models of spontaneous breast cancer, we show enhanced recruitment ...

Malignancy is observed in 5-10% of MN in adults , with the risk being highest in patients over the age of 60. A Solid tumor (such as carcinoma of the lung or colon) is most often involved. It is presumed that tumor antigens are deposited in the glomeruli : this is followed by antibody deposition and complement activation , leading to epithelial cell and basement membran...
Cancer of unknown primary (CUP) is metastatic cancer without a clinically detectable defined tumor site after an adequate diagnostic evaluation. It well recognized that CUP incidence occupies 1-5% all malignant epithelial tumors. Herein, we report case peritoneal carcinoma diagnosed as revealed by laparoscopic surgery.
Despite significant improvement in surgical techniques and chemotherapies, none of the current medical technologies "cure" metastatic disease, and the patients who have acquired metastatic cancer inevitably die from disseminated disease. Thus, there is a need for developing novel therapeutic approaches which can directly target metastatic tumor cells. However, advances in understanding the mole...
