Immunotherapy in synchronous MSI-H rectal adenocarcinoma and upper tract urothelial carcinoma: a case report.

Background: A growing body of evidence suggests that conventional chemotherapy may not be effective in mismatch repair deficiency (dMMR)/microsatellite instability-high (MSI-H) locally advanced rectal cancer (LARC). Alternative strategies, such as immunotherapy, are currently being investigated both in the neoadjuvant and adjuvant setting. Furthermore, immunotherapy is an attractive alternative to the use of combination chemotherapy regimens when treating synchronous primary cancers such as in the setting of inherited cancer syndromes.

Bone Mineral Density at the Time of Initiating Aromatase Inhibitor Therapy Is Associated With Decreased Fractures in Women With Breast Cancer.

Women with estrogen receptor-positive breast cancer who receive an aromatase inhibitor (AI) are at risk for fractures. We aim to determine if dual-energy X-ray absorptiometry (DXA) scans made at the time of AI initiation are associated with decreased fractures. We retrospectively identified 25,158 women with local or regional breast cancer diagnosed between 2005 and 2013 who received AI therapy between 2007 and 2013 from the Medicare-linked Surveillance, Epidemiology, and End Results Program and Texas Cancer Registry databases.

A Case of Chemotherapy-Refractory "THRLBCL like Transformation of NLPHL" Successfully Treated with Lenalidomide.

Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is a subtype of nonclassical Hodgkin lymphoma (HL). It resembles non-Hodgkin lymphoma (NHL), by expressing classic B cell markers such as CD20 and CD79a however lacks definitive HL markers (such as CD15 and CD30). T cell histiocyte-rich large B cell lymphoma (THRLBCL), on the other hand, is a distinct entity classified under NHL and considered a variant of diffuse large B cell lymphoma (DLBCL).

Thymic carcinoma presenting as disseminated intravascular coagulation.

Thymomas and thymic carcinomas are rare tumors, which originate from the epithelial cells of the thymus. We present a case of thymic carcinoma, which presented with DIC as an initial manifestation. DIC improved with corticosteroid treatment and thymic carcinoma was amendable to chemoradiation.
