Association of Adiponectin and Vitamin D With Tumor Infiltrating Lymphocytes and Survival in Stage III Colon Cancer.

Background: Adipocyte-derived adiponectin may play a role in the host inflammatory response to cancer. We examined the association of plasma adiponectin with the density of tumor-infiltrating lymphocytes (TILs) in colon cancers and with vitamin D, clinicopathological features, and patient survival.

Methods: Plasma adiponectin and 25-hydroxyvitamin D [25(OH)D] were analyzed by radioimmunoassay in 600 patients with stage III colon cancer who received FOLFOX-based adjuvant chemotherapy (NCCTG N0147 [Alliance]).

Two Malignancies With Differential Responses to Immune Checkpoint Inhibitors: A Case Report.

Background: Immune checkpoint inhibitors (ICI) have changed the management of cancer dramatically. However, not all patients respond to ICI and their use places patients at a significant risk of immune-related adverse reactions. A few biomarkers including programmed death-1 receptor/programmed death-ligand 1 (PD-1/PD-L1), micro-satellite instability (MSI) status, and tumor mutational burden (TMB) have gained popularity as surrogates to predict responsiveness to ICI.

Randomized controlled trial of individualized treatment summary and survivorship care plans for hematopoietic cell transplantation survivors.

Survivorship Care Plans (SCPs) may facilitate long-term care for cancer survivors, but their effectiveness has not been established in hematopoietic cell transplantation recipients. We evaluated the impact of individualized SCPs on patient-reported outcomes among transplant survivors. Adult (≥18 years at transplant) survivors who were 1-5 years post transplantation, proficient in English, and without relapse or secondary cancers were eligible for this multicenter randomized trial.

Tailoring a Survivorship Care Plan: Patient and Provider Preferences for Recipients of Hematopoietic Cell Transplantation.

This study aimed to develop a survivorship care plan (SCP) that can be individualized to facilitate long-term follow-up care of hematopoietic cell transplantation (HCT) survivors. A sample SCP was developed that included 2 documents: a treatment summary and preventive care recommendations that combined data on treatment exposures routinely submitted by HCT centers to the Center for International Blood and Marrow Transplant Research (CIBMTR) with long-term follow-up guidelines. Focus groups were conducted by phone to characterize the critical patient-centered elements of the SCP.

Physical Activity and Outcomes in Patients with Stage III Colon Cancer: A Correlative Analysis of Phase III Trial NCCTG N0147 (Alliance).

Prior studies have supported an inverse association between physical activity and colon cancer risk and suggest that higher physical activity may also improve cancer survival. Among participants in a phase III adjuvant trial for stage III colon cancer, we assessed the association of physical activity around the time of cancer diagnosis with subsequent outcomes. Before treatment arm randomization (FOLFOX or FOLFOX + cetuximab), study participants completed a questionnaire including items regarding usual daily activity level and frequency of participation in recreational physical activity ( = 1,992).

Nivolumab with or without ipilimumab treatment for metastatic sarcoma (Alliance A091401): two open-label, non-comparative, randomised, phase 2 trials.

Background: Patients with metastatic sarcoma have limited treatment options. Nivolumab and ipilimumab are monoclonal antibodies targeting PD-1 and CTLA-4, respectively. We investigated the activity and safety of nivolumab alone or in combination with ipilimumab in patients with locally advanced, unresectable, or metastatic sarcoma.

Family history of colorectal cancer and its impact on survival in patients with resected stage III colon cancer: results from NCCTG Trial N0147 (Alliance).

Background: Family history of colon cancer often portends increased risk of disease development; however, the prognostic significance of family history related to disease and survival outcomes is unclear.

Methods: To investigate the relationship between family history of colorectal cancer and survival outcomes in stage III colon cancer patients, a prospective cohort of 1,935 patients with resected stage III colon cancer enrolled in a randomized controlled trial (N0147), comparing the standard of care FOLFOX to FOLFOX with cetuximab, was studied. Patients completed a baseline questionnaire on family history and were followed every 6 months until death or 5 years after randomization.

E1308: Phase II Trial of Induction Chemotherapy Followed by Reduced-Dose Radiation and Weekly Cetuximab in Patients With HPV-Associated Resectable Squamous Cell Carcinoma of the Oropharynx- ECOG-ACRIN Cancer Research Group.

Purpose Human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) is treatment-responsive. Definitive chemoradiation results in high cure rates but causes long-term toxicity and may represent overtreatment of some patients. This phase II trial evaluated whether complete clinical response (cCR) to induction chemotherapy (IC) could select patients with HPV-associated OPSCC for reduced radiation dose as a means of sparing late sequelae.

Quantification of pain in sickle mice using facial expressions and body measurements.

Pain is a hallmark feature of sickle cell disease (SCD). Subjects typically quantify pain by themselves, which can be biased by other factors leading to overtreatment or under-treatment. Reliable and accurate quantification of pain, in real time, might enable to provide appropriate levels of analgesic treatment.

Day 14 bone marrow biopsy in predicting complete remission and survival in acute myeloid leukemia.

We retrospectively analyzed 194 previously untreated acute myeloid leukemia (AML) patients to evaluate the role of Day 14 bone marrow (BM) biopsy in predicting complete remission (CR). Sixty-seven percent received induction therapy. Achieving Day 14 BM < or =5% blasts was strongly predictive of Day 28 CR with 90% sensitivity and 79% positive predictive value; but weak 43% specificity and 29% negative predictive value.

Multipotent adult progenitor cell and stem cell plasticity.

Stem cells are defined by their biological function. A stem cell is an undifferentiated cell that self-renews to maintain the stem cell pool and at the single-cell level differentiates into more than one mature, functional cell. In addition, when transplanted, a stem cell should be capable of replacing a damaged organ or tissue for the lifetime of the recipient.

Pluripotency of mesenchymal stem cells derived from adult marrow.

We report here that cells co-purifying with mesenchymal stem cells--termed here multipotent adult progenitor cells or MAPCs--differentiate, at the single cell level, not only into mesenchymal cells, but also cells with visceral mesoderm, neuroectoderm and endoderm characteristics in vitro. When injected into an early blastocyst, single MAPCs contribute to most, if not all, somatic cell types. On transplantation into a non-irradiated host, MAPCs engraft and differentiate to the haematopoietic lineage, in addition to the epithelium of liver, lung and gut.

Emerging fungal pathogens in patients with hematologic malignancies and marrow/stem-cell transplant recipients.

Fungal infections are a major cause of morbidity and mortality among patients with hematologic malignancies and recipients of bone-marrow/hematopoietic stem-cell transplants. Although Candida and Aspergillus species remain the most common fungal pathogens, multiple unusual fungal pathogens are being increasingly recognized as a cause of infection in these patients. Many of these rare fungal infections have a characteristic clinical disease spectrum.

Origin of endothelial progenitors in human postnatal bone marrow.

This study demonstrates that a CD34(-), vascular endothelial cadherin(-) (VE-cadherin(-)), AC133(+), and fetal liver kinase(+) (Flk1(+)) multipotent adult progenitor cell (MAPC) that copurifies with mesenchymal stem cells from postnatal human bone marrow (BM) is a progenitor for angioblasts. In vitro, MAPCs cultured with VEGF differentiate into CD34(+), VE-cadherin(+), Flk1(+) cells - a phenotype that would be expected for angioblasts. They subsequently differentiate into cells that express endothelial markers, function in vitro as mature endothelial cells, and contribute to neoangiogenesis in vivo during tumor angiogenesis and wound healing.
