Leukemic mesenchymal stromal cell COX2-PG signaling regulates donor anti-leukemia immunity
Hematopoietic stem cell transplantation (HSCT) is considered the gold standard for treatment of hematologic malignancies, including Fanconi anemia (FA), a cancer-prone disease with extremely high incidence of myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). However, eradication of residual leukemia stem cells (LSCs), which often contributes to relapse, remains the challenge for HSCT. Here we investigate the interaction between leukemic mesenchymal niche and donor hematopoietic stem progenitor cells (HSPCs) by modeling FA HSCT.

TammelaAbstractWe tested whether intervention with atorvastatin affects the prostate beneficially compared with placebo in men with prostate cancer in a randomized clinical trial. A total of 160 statin-naïve prostate cancer patients scheduled for radical prostatectomy were randomized to use 80 mg atorvastatin or placebo daily from recruitment to surgery fo...

ConclusionRectal surgery in inflammatory conditions is technically challenging. Close rectal dissection is an alternate approach available to colorectal surgeons in these cases to minimize pelvic morbidity and optimize postoperative outcomes.
While we often hear that breakfast is the most important meal of the day, now, new research suggests that the time we eat dinner can affect our cancer risk.

Background: Studies of bone marrow cell clonal alterations in patients with Fanconi anemia (FA), a cancer-prone inherited bone marrow failure (BMF) syndrome, have focused on their role in progression from BMF to myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML). The role of such alterations on patient outcomes after hematopoietic cell transplantation (HCT) is unknown.
Authors: Young Son M, Deng CX, Hoeijmarkers JH, Rebel VI, Hasty P Abstract Benzene is a common environmental toxin and its metabolite, 1-4-Benzoquinone (BQ) causes hematopoietic cancers like myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). BQ has not been comprehensively assessed for its impact on genome maintenance, limiting our understanding of the true health risks associated with benzene exposure and our ability to identify people with increased sensitivity to this genotoxin. Here we analyze the impact BQ exposure has on wild type and DNA repair-defective mouse embryonic stem (ES) cells and wild...
Publication date: September–December 2014 Source:Best Practice & Research Clinical Haematology, Volume 27, Issues 3–4 Author(s): Blanche P. Alter Fanconi anemia (FA) is a rare autosomal recessive cancer-prone inherited bone marrow failure syndrome, due to mutations in 16 genes, whose protein products collaborate in a DNA repair pathway. The major complications are aplastic anemia, acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), and specific solid tumors. A severe subset, due to mutations in FANCD1/BRCA2, has a cumulative incidence of cancer of 97% by age 7 years; the cancers are AML, brain ...
CONCLUSION: In this HHMC-referred hematologic malignancy cohort, HCS was confirmed in 12 patients (18%). HCS identification provides insight for improved and individualized treatment, as well as screening/surveillance opportunities for family members. The HHMC has facilitated HCS diagnosis; with increased clinical awareness of hematologic malignancy predisposition syndromes, more patients who may benefit from evaluation can be identified. Mutation panels intended for prognostication may provide increased clinical suspicion for germ-line testing. PMID: 27210295 [PubMed - as supplied by publisher]
