The Third International Inflammatory Breast Cancer Conference., Kenneth L Van Golen, Massimo Cristofanilli

Department of Medical Oncology Faculty Papers

Inflammatory breast cancer (IBC) is the most aggressive and deadly form of breast cancer. Disease-specific research and conferences have been organized since 2008 with the intent to bring together experts in various disciplines. This report focus on the Third International IBC Conference held in Philadelphia on December 2012.

Recommendations For High-Priority Research On Cancer-Related Fatigue In Children And Adults., Andrea M. Barsevick, Michael R. Irwin, Pamela Hinds, Andrew Miller, Ann Berger, Paul Jacobsen, Sonia Ancoli-Israel, Bryce B Reeve, Karen Mustian, Ann O'Mara, Jin-Shei Lai, Michael Fisch, David Cella

Over the past decades, some scientific progress has been made in understanding and treating cancer-related fatigue (CRF). However, three major problems have limited further progress: lack of agreement about measurement, inadequate understanding of the underlying biology, and problems in the conduct of clinical trials for CRF. This commentary reports the recommendations of a National Cancer Institute Clinical Trials Planning Meeting and an ongoing National Cancer Institute working group to address these problems so that high-priority research and clinical trials can be conducted to advance the science of CRF and its treatment. Recommendations to address measurement issues included revising the current …

A 2-Step Approach To Myeloablative Haploidentical Stem Cell Transplantation With Optimized T-Cell Dosing: Early Immune Reconstitution Leads To Better Outcomes, Sameh Gaballa, Onder Alpdogan, Matthew Carabasi, Joanne Filicko, Margaret Kasner, Ubaldo E. Martinez-Outshoorn, Md, John L Wagner, Mark Weiss, Neal Flomenberg, Delores Grosso

We developed a 2-step approach to myeloablative haploidentical HSCT in which patients receive a large fixed dose of cyclophosphamide (CY)-tolerized T cells separately frm the HSC infusion in the hopes of accelerating post HSCT immune reconstitution (IR). The uniformity of the T cell dosing facilitates comparison of patients without (low risk) and with (high risk) active malignancy at HSCT to ascertain the impact of disease status at HSCT on IR with fewer confounding effects from conditioning or T cell dosing.

Gender Differences In Attitudes Impeding Colorectal Cancer Screening., Paul Ritvo, Ronald E. Myers, Lawrence Paszat, Mardie Serenity, Daniel F Perez, Linda Rabeneck

Department of Medical Oncology Faculty Papers

BACKGROUND: Colorectal cancer screening (CRCS) is the only type of cancer screening where both genders reduce risks by similar proportions with identical procedures. It is an important context for examining gender differences in disease-prevention, as CRCS significantly reduces mortality via early detection and prevention. In efforts to increase screening adherence, there is increasing acknowledgment that obstructive attitudes prevent CRCS uptake. Precise identification of the gender differences in obstructive attitudes is necessary to improve uptake promotion. This study randomly sampled unscreened, screening - eligible individuals in Ontario, employing semi-structured interviews to elicit key differences in attitudinal obstructions towards colorectal cancer screening …

Presence Of Anaplastic Lymphoma Kinase In Inflammatory Breast Cancer., Fredika M Robertson, Emanuel F Petricoin Iii, Steven J Van Laere, Francois Bertucci, Khoi Chu, Sandra V Fernandez, Zhaomei Mu, Katherine Alpaugh, Jianming Pei, Rita Circo, Julia Wulfkuhle, Zaiming Ye, Kimberly M Boley, Hui Liu, Ricardo Moraes, Xuejun Zhang, Ruggero Demaria, Sanford H Barsky, Guoxian Sun, Massimo Cristofanilli

Although Inflammatory Breast Cancer (IBC) is recognized as the most metastatic variant of locally advanced breast cancer, the molecular basis for the distinct clinical presentation and accelerated program of metastasis of IBC is unknown. Reverse phase protein arrays revealed activation of the receptor tyrosine kinase, anaplastic lymphoma kinase (ALK) and biochemically-linked downstream signaling molecules including JAK1/STAT3, AKT, mTor, PDK1, and AMPKβ in pre-clinical models of IBC. To evaluate the clinical relevance of ALK in IBC, analysis of 25 IBC patient tumors using the FDA approved diagnostic test for ALK genetic abnormalities was performed. These studies revealed that 20/25 (80%) had …

Dysregulated Methylation At Imprinted Genes In Prostate Tumor Tissue Detected By Methylation Microarray., Daniel I Jacobs, Yingying Mao, Alan Fu, William Kevin Kelly, Yong Zhu

Department of Medical Oncology Faculty Papers

BACKGROUND: Imprinting is an important epigenetic regulator of gene expression that is often disrupted in cancer. While loss of imprinting (LOI) has been reported for two genes in prostate cancer (IGF2 and TFPI2), disease-related changes in methylation across all imprinted gene regions has not been investigated.

METHODS: Using an Illumina Infinium Methylation Assay, we analyzed methylation of 396 CpG sites in the promoter regions of 56 genes in a pooled sample of 12 pairs of prostate tumor and adjacent normal tissue. Selected LOI identified from the array was validated using the Sequenom EpiTYPER assay for individual samples and further confirmed …

Ezh2 Knockdown Suppresses The Growth And Invasion Of Human Inflammatory Breast Cancer Cells., Zhaomei Mu, Hua Li, Sandra V Fernandez, Katherine R Alpaugh, Rugang Zhang, Massimo Cristofanilli

Department of Medical Oncology Faculty Papers

INTRODUCTION: Inflammatory breast cancer (IBC) is the most metastatic variant of breast cancer with the poorest survival in all types of breast cancer patients and presently therapeutic targets for IBC are very limited. Enhancer of zeste homolog 2 (EZH2) is frequently expressed in human IBC and its expression positively correlates with worse clinical outcome. However, the molecular basis for EZH2 promoting IBC has not been explored. Here, we investigated the functional role of EZH2 in IBC cells by examining the effects of its knockdown on the formation of tumor spheroids and invasion of these cells in vitro and in vivo …
