The identification of the molecular drivers of cancer by sequencing is the backbone of precision medicine and the basis of personalized therapy; however, biopsies of primary tumors provide only a snapshot of the evolution of the disease and may miss potential therapeutic targets, especially in the metastatic setting. A liquid biopsy, in the form of cell-free DNA (cfDNA) sequencing, has the pote...

A clinically relevant model of spontaneous breast cancer metastasis to multiple sites, including bone, was characterized and used to identify genes involved in metastatic progression. The metastatic potential of several genetically related tumor lines was assayed using a novel real-time quantitative RT-PCR assay of tumor burden. Based on this assay, the tumor lines were categorized as nonmetast...

Tumor is defined as a kind of chronic diseases by the World Health Organization. The integrative traditional Chinese and western medicine works well on treatment tumors, even in advanced patients or with recurring metastatic tumor. However, pathogenic mechanism tumors still unclear. Therefore, based 19th pathogenesis Yellow Emperor's Internal Class that "Diseases producing liquid clear chill al...

Nonfunctional adrenocortical carcinoma is an extremely rare malignant tumor in children. Unlike the functional tumor which is detected early due to its hormonal presentation, nonfunctional tumor is detected at a later stage. Here we report a case of a 10 year old girl who presented with abdominal mass and symptoms of short duration. No hypertension and cushingoid features were seen. Serum alpha...

Melanocortin-1 (MC1) receptor is an attractive melanoma-specific target for the development of α-MSH peptide based imaging and therapeutic agents. In this work a new lactam bridge α-MSH analogue was synthesized and radiolabeled with 99mTc via HYNIC chelator and tricine as co-ligand. Also, stability in human serum, receptor bound internalization and tissue biodistribution in tumor bearing nude m...

A patient with microscopic metastatic renal cell carcinoma within liver focal nodular hyperplasia (FNH) is reported here. The initial CT scan was classic for liver FNH yet the following liver resection showed a microscopic metastatic renal cell carcinoma (0.48 cm) within the liver nodule. FNH in a patient with existing primary tumor probably warrants further investigation as the coexistence of ...

BACKGROUND AND PURPOSE MR image-guided gamma knife radiosurgery is often used to treat intra-axial metastatic neoplasms. Following treatment, it is often difficult to determine whether a progressively enhancing lesion is due to metastatic tumor recurrence or radiation necrosis. The purpose of our study was to determine whether relative cerebral blood volume (rCBV), relative peak height (rPH), a...

Krukenberg tumor is an interesting and rare tumor which usually but not always is metastatic. Ovaries more than any other genital pelvic organs are the site of metastasis. Endometrium, gastrointestinal tract and breast are the most common primary sites. The best method of treatment is surgery. Postoperatively, radiotherapy and chemotherapy must be performed. 3 cases of Krukenberg tumor dia...

The pre-metastatic niche educated by primary tumor-derived elements contributes to cancer metastasis. However, the role of host stromal cells in metastatic niche formation and organ-specific metastatic tropism is not clearly defined. Here, we demonstrate that lung epithelial cells are critical for initiating neutrophil recruitment and lung metastatic niche formation by sensing tumor exosomal RN...
