Increased expression of musashi 1 on breast cancer cells has implication to understand dormancy and survival in bone marrow.

Breast cancer (BC) stem cells (CSCs) resist treatment and can exist as dormant cells in tissues such as the bone marrow (BM). Years before clinical diagnosis, BC cells (BCCs) could migrate from the primary site where the BM niche cells facilitate dedifferentiation into CSCs. Additionally, dedifferentiation could occur by cell autonomous methods.

Harnessing antitumor immunity: Employment of tumor recall antigens to optimize the inflammatory response to cancer.

The advent of immunotherapy for cancer has contributed to the era of personalized medicine for cancer. The various immunotherapy-based treatments that have been explored thus far include monoclonal antibody therapy, tumor vaccines, immune checkpoint blockade and adoptive T cell transfer, among others. The groundwork for all these immunotherapeutic modalities rests within the tumor microenvironment, specifically the immune factors that influence the tumor-drug interface.

Progressive Multifocal Leukoencephalopathy with Negative JC Virus PCR following Treatment of Follicular Lymphoma: Implications for Biologics in the Era of Targeted Cancer Therapy.

Anticancer therapy predisposes patients to infections by the immunosuppression that results from treatment. Although 85% of patients with progressive multifocal leukoencephalopathy (PML) have concurrent HIV/AIDS, PML can also develop in patients after they receive chemotherapy for cancer. The case herein describes a 69-year-old man with history of follicular lymphoma who presented with progressive dysarthria and right-sided paralysis.
