To integrate the patient perspective into adverse event reporting, the National Cancer Institute developed a patient-reported outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE).To assess the construct validity, test-retest reliability, and responsiveness of PRO-CTCAE items.A total of 975 adults with cancer undergoing outpatient chemotherapy and/or radiation therapy enrolled in this questionnaire-based study between January 2011 and February 2012. Eligible participants could read English and had no clinically significant cognitive impairment. They completed PRO-CTCAE items on tablet computers in clinic waiting rooms at 9 US cancer centers and community oncology practices at 2 visits 1 to 6 weeks apart. A subset completed PRO-CTCAE items during an additional visit 1 business day after the first visit.Primary comparators were clinician-reported Eastern Cooperative Oncology Group Performance Status (ECOG PS) and the European Organisation for Research and Treatment of Cancer Core Quality of Life Questionnaire (QLQ-C30).A total of 940 of 975 (96.4%) and 852 of 940 (90.6%) participants completed PRO-CTCAE items at visits 1 and 2, respectively. At least 1 symptom was reported by 938 of 940 (99.8%) participants. Participants median age was 59 years; 57.3% were female, 32.4% had a high school education or less, and 17.1% had an ECOG PS of 2 to 4. All PRO-CTCAE items had at least 1 correlation in the expected direction with a QLQ-C30 scale (111 of 124, P<.05 for all). Stronger correlations were seen between PRO-CTCAE items and conceptually related QLQ-C30 domains. Scores for 94 of 124 PRO-CTCAE items were higher in the ECOG PS 2 to 4 vs 0 to 1 group (58 of 124, P<.05 for all). Overall, 119 of 124 items met at least 1 construct validity criterion. Test-retest reliability was 0.7 or greater for 36 of 49 prespecified items (median [range] intraclass correlation coefficient, 0.76 [0.53-.96]). Correlations between PRO-CTCAE item changes and corresponding QLQ-C30 scale changes were statistically significant for 27 prespecified items (median [range] r=0.43 [0.10-.56]; all P.006).Evidence demonstrates favorable validity, reliability, and responsiveness of PRO-CTCAE in a large, heterogeneous US sample of patients undergoing cancer treatment. Studies evaluating other measurement properties of PRO-CTCAE are under way to inform further development of PRO-CTCAE and its inclusion in cancer trials.

Recruitment of monocytic myeloid-derived suppressor cells (MDSCs) and differentiation of tumor-associated macrophages (TAMs) are the major factors contributing to tumor progression and metastasis. We demonstrated that differentiation of TAMs in tumor site from monocytic precursors was controlled by downregulation of the activity of the transcription factor STAT3. Decreased STAT3 activity was caused by hypoxia and affected all myeloid cells but was not observed in tumor cells. Upregulation of CD45 tyrosine phosphatase activity in MDSCs exposed to hypoxia in tumor site was responsible for downregulation of STAT3. This effect was mediated by the disruption of CD45 protein dimerization regulated by sialic acid. Thus, STAT3 has a unique function in the tumor environment in controlling the differentiation of MDSC into TAM, and its regulatory pathway could be a potential target for therapy. © 2016 Elsevier Inc.

Cancer testis antigens (CTAs) are widely expressed in tumor tissues, circulating tumor cells (CTCs) and in cancer derived exosomes that are frequently engulfed by lymphoid cells. To determine whether tumor derived CTA mRNAs could be detected in RNA from purified peripheral blood mononuclear cells (PBMC) of non-small cell lung cancer (NSCLC) patients, we assayed for the expression of 116 CTAs in PBMC RNA in a discovery set and identified AKAP4 as a potential NSCLC biomarker. We validated AKAP4 as a highly accurate biomarker in a cohort of 264 NSCLCs and 135 controls from 2 different sites including a subset of controls with high risk lung nodules. When all (264) lung cancers were compared with all (135) controls the area under the ROC curve (AUC) was 0.9714. When 136 stage I NSCLC lung cancers are compared with all controls the AUC is 0.9795 and when all lung cancer patients were compared to 27 controls with histologically confirmed benign lung nodules, a comparison of significant clinical importance, the AUC was 0.9825. AKAP4 expression increases significantly with tumor stage, but independent of age, gender, smoking history or cancer subtype. Follow-up studies in a small number of resected NSCLC patients revealed a decrease of AKAP4 expression post-surgical resection that remained low in patients in remission and increased with tumor recurrence. AKAP4 is a highly accurate biomarker for the detection of early stage lung cancer.

There has been little attention paid to the role of therapeutic processes in group therapy outcomes for cancer patients participating in group. The goal was to evaluate the contribution of 3 group processes-group climate (conflict, engagement, and avoidance) working alliance and therapeutic realizations-to the outcomes of 2 couple-focused approaches to group treatment.Three hundred and two women with early stage breast cancer and their partners were randomized to one of 2 conditions: an 8-session enhanced couple-focused group (ECG) intervention or a couples support group participated. Couples completed measures of depressive symptoms and well-being before and 6months after group. Group process measures were completed after sessions 4 and 8.Support group participants (both patients and partners) perceived higher engagement and less avoidance than ECG participants. Conflict, working alliance, and therapeutic realizations did not differ. Group engagement, working alliance, and therapeutic realizations increased, and group conflict decreased over the course of both treatments. Greater conflict was associated with more posttreatment anxiety and lower well-being, and engagement was associated with higher posttreatment well-being. Patients whose partners reported higher conflict reported greater posttreatment anxiety. Working alliance was associated with posttreatment anxiety for ECG patients and with well-being among participants whose partners reported higher working alliance.Fostering a positive group environment bolsters treatment efficacy for women with early stage breast cancer and their partners attending couple-focused groups. Facilitating the leader-member alliance bolsters treatment efficacy. Improving engagement with one member of a couple impacts the other member.

A growing body of evidence indicates that microRNA23b (miR23b) is pleiotropic—it plays important roles in regulating physiological functions of cells, in regulating differentiation of cells and in regulating cellular immune responses. Our review of the literature showed that dysregulation of miR23b expression is implicated in the disruption of these cellular mechanisms and development of diseases such as cancer. MiR23b dysregulation appears to do this by modulating the expression level of candidate gene products involved in a network of signaling pathways including TGF-beta and Notch pathways that govern malignant properties of cancer cells such as motility and invasiveness. More recently, miR23b regulation of gene expression has also been associated with cancer stem cells and chemoresistance. Our review covers miR23b’s role in immunity, endothelial function, differentiation, and cancer as well as its potential for translation into future cancer diagnostics and therapeutics. © 2014, Springer-Verlag Berlin Heidelberg.

More than 50% of states have state-mandated density notification for patients with heterogeneously or extremely dense breasts. Increased breast density carries a risk of masking a cancer and delaying diagnosis. Supplemental imaging is optional and often recommended for certain patients. There are no evidence-based consensus guidelines for screening patients with density as their only risk factor. Breast cancer risk assessment and breast cancer prevention strategies should be discussed with women with dense breasts.

The role of the cancer genetic counselor in the management of patients with cancer is discussed in this article. This includes explaining what a genetic counselor is trained to do and how they are credentialed and licensed. In addition, the article explains who to refer for cancer genetic counseling. Once referred, the article describes what actually happens in a pretest and posttest cancer genetic counseling session. Use of a cancer genetic registry and how it can help in practice is discussed. Finally, several mechanisms for identifying a cancer genetic counselor at ones institution or nearby are outlined.

Effective new agents for patients with colorectal cancer (CRC) with disease progression during standard therapy regimens are needed. We hypothesized that poly ADP ribose polymerase (PARP) inhibitor therapy in patients with CRC and inefficient tumor DNA repair mechanisms, such as those with high-level microsatellite instability (MSI-H), would result in synthetic lethality.This was an open-label phase II trial testing olaparib 400 mg p.o. b.i.d. for patients with disseminated, measurable CRC failing standard therapies with centrally confirmed tumor MSI status. The primary endpoint was the tumor response, assessed by RECIST, version 1.0. The secondary endpoints were safety/toxicity, progression-free survival (PFS), and overall survival (OS).Thirty-three patients (20 microsatellite stable [MSS], 13 MSI-H) were enrolled. The median age for all patients was 57 years and for MSS and MSI-H patients was 51 and 61 years, respectively. All patients received at least one 28-day cycle of olaparib. No patient had a complete or partial response. Nausea (48%), fatigue (36%), and vomiting (33%) were the most commonly reported treatment-related adverse events. The median PFS for all patients was 1.84 months. No statistically significant differences were found in the median PFS or OS for the MSS group compared with the MSI-H group.Single-agent olaparib delivered after failure of standard systemic therapy did not demonstrate activity for CRC patients, regardless of microsatellite status. Future trials, testing PARP inhibitors in patients with CRC should focus on the use of DNA-damaging chemotherapy and/or radiation therapy, combined with PARP inhibitors, remembering the toxicity reported in the present study.Microsatellite instability (MSI-H) colorectal tumors exhibit hypermethylation in tumor mismatch repair genes, or have mutations in one or more of these genes resulting from a germ-line defect (Lynch syndrome). PARP inhibitors such as olaparib are most effective in tumors associated with inability to repair DNA damage. However, in this trial, single agent olaparib failed to elicit responses in patients with MSI-H colorectal tumors, and in those with microsatellite-stable tumors. It is possible that by adding olaparib to radiation therapy, or to a systemic DNA damaging agent, tumor lethality could be obtained. However, the price would be increased toxicity.

Over the last 40 years the National Cancer Institute (NCI) has created a vibrant public-private partnership for the implementation of NCI-sponsored cooperative group (Network) clinical trials throughout the United States and Canada. Over these four decades, the cancer clinical trials process has become more complex more precise and more resource intensive. During this same time period, financial resources to support the NCI community research initiative have become more constrained. The newest manifestation of NCI-sponsored community based cancer clinical trial research, known as the National Community Oncology Research Program (NCORP) began initial operation August 1, 2014. We describe several key strategies that community sites may use to not only be successful but to thrive in this new financially austere research environment.

A small population of highly tumorigenic breast cancer cells has recently been identified. These cells, known as breast-cancer stem-like cells (BCSC), express markers similar to mammary stem cells, and are highly resistant to chemotherapy. Currently, study of BCSC is hampered by the inability to propagate these cells in tissue culture without inducing differentiation. Recently, it was reported that proliferation and differentiation can be modified by culturing cells on electrospun nanofibers. Here, we sought to characterize the chemoresistance and stem-like properties of breast cancer cell lines grown on nanofiber scaffolds. Cells cultured on three-dimensional templates of electrospun poly(?-caprolactone)-chitosan nanofibers showed increases in mammary stem cell markers and in sphere-forming ability compared with cells cultured on polystyrene culture dishes. There was no increase in proliferation of stem cell populations, indicating that culture on nanofibers may inhibit differentiation of BCSC. The increase in stemness was accompanied by increases in resistance to docetaxel and doxorubicin. These data indicate that BCSC populations are enriched in cells cultured on electrospun poly(?-caprolactone)-chitosan nanofibers, scaffolds that may provide a useful system to study BCSC and their response to anticancer drug treatment. © 2014 Sims-Mourtada et al.
