A Cutting-Edge Fertility Technique For Pediatric Cancer Patients

CHICAGO (AP) -- Barely 2 years old, Talia Pisano is getting tough treatment for kidney cancer that spread to her brain. She's also getting a chance at having babies of her own someday.  To battle infertility sometimes caused by cancer treatment, some children's hospitals are trying a futuristic approach: removing and freezing immature ovary and testes tissue, with hopes of being able to put it back when patients reach adulthood and want to start families. No one knows yet if it will work. It has in adults - more than 30 babies have been born to women who had ovarian tissue removed in adulthood, frozen, and put back after treatment for cancer or other serious conditions. In lab animals, it's worked with frozen and thawed testes tissue. But the procedures are still experimental in children who haven't reached puberty, and too new to have been attempted. There are challenges to making immature eggs and sperm from removed tissue suitable for conception. Still, fertility researchers hope to refine the science while the first generation of children whose tissue has been put on ice grows up. Families like Talia's are clinging to that optimism. The dark-eyed toddler who loves princesses and play dough had an ovary removed and frozen in April. She was treated for kidney cancer last year but when it spread, doctors started harsher treatment including brain radiation. "It seemed very new and pretty amazing that we can do something like this and help her in a bigger way," ...

PerskyAbstractClassical Mantle cell lymphoma (cMCL) is a B-cell neoplasm characterized immunohistochemically by their CD5+, CD19+, CD20+, CD23- and cyclinD1+ nature and confirmed genetically by the presence of t(11;14), resulting in the over-expression of Cyclin D1. Classical MCL generally presents with adenopathy, spleen, bone marrow involvement and extra-nodal sites most commonly the GI tract...

The peripheral blood mononuclear cells (PBMCs) from a patient with PM were successfully reprogrammed to induced pluripotent stem cells (iPSCs) using integration-free method, Sendai viral (SeV) vectors expressing OCT4, SOX2, KLF4 and C-MYC. This line may provide a useful resource for exploring the pathogenesis of PM.

Authors: Bondeelle L, Bergeron A Abstract INTRODUCTION: Progress in allogeneic hematopoietic stem cell transplantation (HSCT) procedures have been associated with improved survival in HSCT recipients. However, they have also brought to light organ-specific complications, especially pulmonary complications. In this setting, pulmonary complications are consistently associated with poor outcomes, and improved management of these complications is required. Areas covered: We review the multiple infectious and noninfectious lung complications that occur both early and late after allogeneic HSCT. This includes the descrip...

In the present study, we found that overexpression of M-CSFR was present in adult T-cell leukemia/lymphoma (ATLL) cases. M-CSFR signaling was associated with lymphoma cell proliferation, and M-CSFR inhibition induced apoptosis in lymphoma cells. ...

Oncol Rep. 2018 Oct 31;: Authors: Peng JX, Liang SY, Li L Abstract Secreted frizzled‑related protein 1 (sFRP1) is an inhibitor of canonical Wnt signaling; however, previous studies have determined a tumor‑promoting function of sFRP1 in a number of different cancer types. A previous study demonstrated that sFRP1 overexpression was associated with an aggressive phenotype and the activation of transforming growth factor β (TGFβ) signaling. sFRP1 overexpression and...
