Anaplastic Sarcoma of the Kidney: A Rare Unique Renal Neoplasm

Anaplastic sarcoma of the kidney (ASK) is an extremely rare tumor, which usually presents as a large renal mass. Microscopically, the tumor is composed of pleomorphic mesenchymal spindle cells with marked atypia, associated with chondroid differentiation and focal round primitive mesenchymal cells. Herein, we present a case of anaplastic sarcoma of the kidney in a 3-year-old female, who presented with a large abdominal mass. To the best of our knowledge, less than 25 cases are reported in the literature. In addition, this is the first case reported from the Middle East.

ConclusionsThe onset of hepatic metastasis indicates a poor prognosis. However, hepatic metastasis from retroperitoneal sarcoma and leiomyosarcoma may be the first distant metastasis in some cases. For retroperitoneal sarcoma and leiomyosarcoma, additional screening for hepatic metastasis such as contrast CT should be considered during staging and follow ‐up after treatment.

We developed a method of reproducing malignant process in the lungs of rats with stimulation by chronic neurogenic pain. In white outbred male rats, chronic neurogenic pain was modeled by bilateral ligation of the sciatic nerves and in 45 days, a suspension of M1 sarcoma cells (106 cells/liter in 0.3 ml physiological saline) was injected into the subclavian vein. In almost all rats receiving transplantation of tumor cells against the background of chronic neurogenic pain, tumor foci in the lungs were detected in 1.5-2.0 months and led to the death of the animals.

This study aimed to establish a novel alveolar soft-part sarcoma cell line. Using surgically-resected tumor tissue of alveolar soft-part sarcoma, we successfully established a cell line and named it NCC-ASPS1-C1. The NCC-ASPS1-C1 cells harbored anASPSCR1-TFE3 fusion gene and exhibited slow growth, and spheroid formation. On the other hand, NCC-ASPS1-C1 did not show the capability of invasion. We screened the antiproliferative effects of 195 anticancer agents, including Food and Drug Administration-approved anticancer drugs. We found that the MET inhibitor tivantinib and multi-kinase inhibitor orantinib inhibited the prolif...

Authors: Angelico G, Santoro A, Inzani F, Martini M, D'Alessandris N, Spadola S, Valente M, Arciuolo D, Sfregola S, Mule' A, Scambia G, Zannoni GF Abstract Secondary malignancies arising within mature teratomas are a rare event, originating from malignant transformation of the tissues derived from one of the three germ cell layers. Osteogenic melanoma is exceedingly rare histologic variant of malignant melanoma, in which the melanoma is associated to an osteogenic sarcoma component. To the best of our knowledge, first case of osteogenic melanoma arising within mature ovarian teratoma in a 30-year-old woman without ...

This study involved a retrospective analysis of 22 patients with BM from sarcomas who underwent resection at six institutes in Japan. Prognostic factors were analyzed to develop a graded prognostic assessment (GPA) using the log-rank test and Cox regression analysis. For validation of this GPA, we collected data on 100 surgical cases from 48 published reports.ResultsPostoperative Karnofsky Performance Status (KPS) improved in 50% of our patients. Median overall survival (OS) was 21  months. Multivariate analysis showed age and alveolar soft part sarcoma (ASPS) were significant preoperative prognostic factors (P
