Histologic Variations and Immunohistochemical Features of Metastatic Clear Cell Renal Cell Carcinoma
BACKGROUND Due to advancements in treatment of metastatic and advanced renal cell carcinoma (RCC), it has become increasingly important to diagnose metastatic RCC and the specific subtype. In this study, we investigated the diverse histologic features of metastatic clear cell renal cell carcinoma (CCRCC) cases in comparison with corresponding primary lesions. METHODS We identified 119 metasta...
Evaluation of Receptor Conversion and HER2 Discordance between Primary Metastatic Breast Cancer Predictive factors
Observation of the clinical outcomes in Temozolomide and radiotherapy Combination against metastatic brain tumors
objective(s): we performed a phase iia clinical trial of trans-1-amino-3-18ffluoro-cyclobutane carboxylic acid (anti-18f-facbc), a synthetic amino acid analog for pet, in patients with metastatic prostate cancer. methods: the study subjects consisted of 10 untreated prostate cancer patients having lymph node and/or bone metastasis. five patients underwent whole-body pet 5 and 30 min after intra...
introduction:most metastatic lymph nodes from head and neck malignancy are solid. cystic nodes are found in 33% - 61% of carcinomas arise from waldeyer’s ring, of which only 1.8% - 8% originate are from the nasopharynx. some cystic cervical metastases were initially presumed to be branchial cleft cyst. this case report aims to highlight the unusual presentation of cystic cervical metastasis sec...
Following v-Ha-ras transfection of nonmetastatic dimethylbenz(( a ))anthracene-induced rat mammary cancer (RMC1) cells, occasional transfectants were isolated that acquired high metastatic ability. High metastatic ability is not a simple process regulated by v-Ha-ras p21 levels alone in these v-Ha-ras transfectants but involves the development of cytogenetic changes. If such cytogenetic changes...
OBJECTIVES Population-based data on metastatic sites and survival in site-specific metastases are lacking for lung cancer and for any cancer because most cancer registries do not record metastases. This study uses a novel population-based approach to identify metastases from both death certificates and national inpatient data to describe metastatic pathways in lung cancer patients. MATERIALS ...
Radiation and cisplatin-based chemotherapy are major treatments for nasopharyngeal carcinoma (NPC). However, a major impediment for further improving the cure rate is the development of treatment resistance with an undetermined molecular mechanism in metastatic NPC cells. Our established, highly metastatic NPC cells have been reported to be more resistant to cisplatin chemotherapy. In the prese...
The failure to treat metastatic cancer with multidrug resistance is a major problem for successful cancer therapy, and the molecular basis for the association of metastatic phenotype with resistance to therapy is still unclear. In this study, we revealed that various metastatic cancer cells showed consistently higher levels of antiapoptotic proteins, including Bcl-2, nuclear factor-kappaB, MDM2...
The centrosome plays a key role in cancer invasion and metastasis. However, it is unclear how abnormal centrosome numbers are regulated when prostate cancer (PCa) cells become metastatic. CP110 was previously described for its contribution of centrosome amplification (CA) and early development of aggressive cell behaviour. However its regulation in metastatic cells remains unclear. Here we iden...
