- Further clarification of the “rare cancer cell line project” announced on a previous E-Bulletin.The cancer cell line project is a collaborative effort of the Broad Institute of MIT/Harvard and the Rare Cancer Research Foundation, a non-for profit foundation. This project was created because both parties felt that there were not enough “living” cancer cell lines of rare cancer in existence and the lack of sufficient cell line was hindering the advancement of research on these rare tumors. The Project does receive some funding from the NIHA little more background information would be helpful. The Broad Institute of MIT and Harvard was launched in 2004 to improve human health by using genomics to advance our understanding of the biology and treatment of human disease, and to help lay the groundwork for a new generation of therapies. If you wish you can learn more about the Broad Institute of MIT and Harvard on their official website https://www.broadinstitute.org. More information about the Rare Cancer Research Foundation can be obtained on their website.The Cancer Cell line Project is not a new project. However, inclusion of Leiomyosarcoma into the small group (8 previous rare cancers in the project) is NEW. The Cancer Cell line Project was looking to add a few more rare cancers to those already in the project. The NLMSF working with the RCRF was able to get LMS accepted as one of the new rare cancers in the project. Our application had to be accepted by both the RCRF and the Broad Institute.The Cancer Cell Line Project is under the purview of the Institutional Review Board (IRB) of the Broad institute. In accordance with FDA regulations, and IRB which is an independent entity, had the authority to approve, require modifications in (to secure approval) or disapprove research. This group review serves an important role in the protection of the rights and welfare of human research subjects. The IRB provides ongoing oversight of the research to ensure compliance.The Cancer Cell Line Project is not in the in a strict definition a specific research project. Its goal to develop “living” rare cancer lines (tissue cell cultures) that they can then genomically characterize and then share with other researchers throughout the world for use in their research endeavors. Those researchers if they have the means to do so can also continue to “grow” the tumor cell lines in their labs for future research. A created tumor cell line is truly remarkable thing. The gift to patients that keeps on giving.As most of you probably already know, there is an LMS Tissue Bank at Dr. Matt Van de Rijn’s lab at Stanford. This is one of if not the largest collections of LMS patient tumor samples in the world. It is a tremendous resource for LMS researchers. The NLMSF strongly supports this tissue bank and encourages all LMS patients to have paraffin block samples of their tumors sent to this tissue bank for use in current and future research projects. Our foundation has helped to fund research in Dr. van de Rijn’s lab for many years and he recently graciously accept to become a member of the Medical Advisory Committee of our Foundation.The Broad Institute Cell Line Project does not conflict or compete with the LMS Tissue Bank at Stanford. These are complementary projects that in different ways will help to advance LMS research. The Cancer Cell Lines developed at the Broad Institute require fresh tumor tissue samples for their creation. Living cancer cell lines cannot be created from tissue stored in paraffin block. That is why tumor cell line creation is not only difficult and costly, but also requires coordination at many levels. That is why so few tumor cell lines exist.The beauty of the collaborative project of the RCRF and the Broad Institute is that do to funding that they have been able to attain they have made the acquisition of a sample fresh of a patient’s tumor tissue obtained at the time of surgery or biopsy at any hospital in the United States as easy as possible.
Other than giving consent to donate a small portion of their tumor tissue sample, a portion not needed for their treatment, the process proceeds without any involvement or effort by the patient. The patient’s tumor tissue sample is de-identified before it is sent to the Broad Institute. The researchers creating the tumor cell line will know no personal information about the patient who donated the tissue. The patient will not receive any information back about their tumor or any future research done on their tumor.The choice to donate a sample of their tumor tissue to the Cancer Cell Line Project is solely and completely up to the patient. It is an on-line process. The NLMSF’s involvement is only to inform you that the project exists. We will have no knowledge of who chooses to participate. The NLMSF will receive no financial gain or other compensation from the RCRF or the Broad institute.

- The National Leiomyosarcoma Foundation announces an exciting new collaborative partnership with the Rare Cancer Research Foundation (RCRF), which will allow Leiomyosarcoma (LMS) patients to DIRECTLY DONATE their FRESH TUMOR TISSUE to be used for the creation of new LMS TUMOR CELL LINES, which can be used for future LMS research by researchers throughout the world.The RCRF has created a program with the Broad Institute of MIT and Harvard dedicated to the creation of new tumor cell lines of rare cancers called The Cancer Cell Line Project”. Only a limited number of rare cancers are and will be included in this project. Cell Lines mean: tumor tissue in vitro (Petri dish) for analysis and testing to continue to grow more tumor tissue/cells for further research study initiatives.

- Community Healthcare Systems Seeking To Incorporate Genetic Testing Into Cancer Care They Offer:
The Wall Street Journal (3/6, Kincaid, Subscription Publication, 6.37M) reports community healthcare systems are seeking to incorporate genetic testing into the cancer care they provide. Richard Schilsky, chief medical officer of the American Society of Clinical Oncology, points out that most patients with cancer receive care in a community setting, though testing tumors for multiple genetic mutations has been more prevalent in academic settings where oncologists have the resources to interpret complicated results.CHECK WITH YOUR OWN ONCOLOGIST IF YOU ARE INTERESTED IN PURSUING THIS.

- OncLive Insights Videos from three research oncologists
- Seth M. Pollack, assistant professor, Division of Oncology, University of Washington, and attending physician, Seattle Cancer Care Alliance, discusses the role of radiomics in the treatment landscape of sarcoma. Radiomics, which is a fairly new field of study, quantifies complex aspects of tumor images related to tumor biology. Prior research has validated its use in predicting patient outcomes in lung and head and neck cancers. According to Pollack, sarcoma may be an ideal treatment landscape in which to study radiomics because so many patients with this disease already undergo MRIs as part of their overall treatment. This essentially provided the rationale for examining radiomics in this particular patient population. In his research, Pollack found that, after patients’ tumor images were analyzed through a list of radiomic features, the model that was made to predict outcomes was extremely accurate. In fact, it was found to be more accurately predictive than other standard factors, such as those based on tumor grade, tumor size, and other clinical features. – See more at: http://www.onclive.com/onclive-tv/dr-pollack-on-the-role-of-radiomics-in-sarcoma#sthash.XFZMhYEU.dpuf

- 2016 CTOS Annual Meeting in Libson, Portugal: The National Leiomyosarcoma Foundation represented the LMS Community at the 2016 Connective Tissue Oncology Conference in Lisbon, Portugal. Dr. Achee and I traveled to Portugal on our own to represent LMS patients and their families, as is the case for all conferences as well as patient programs hosted in cities across the United States and abroad by the Foundation. The landmark $1 million dollar Collaborative International LMS Research Project, initiated by the Liddy Shriver Initiative, was discussed at a special session hosted by the Liddy Shriver Initiative, who brought together the esteemed researchers for such a large scale research project, which launched in August. This session was to brief other researchers at the conference who also have an interest in LMS research efforts and perhaps already involved in research projects of their own. This is truly a “gift of hope” on a global scale for the LMS community. We are so thankful for the opportunity, and grateful to Bruce and Beverly Shriver – the Liddy Shriver Initiative – for bringing us all together for such a promising research breakthrough potential and ultimately to make a difference for hopeful acceleration of treatment advancements for the future. We salute all who could come together to support the vision and mission of this particular Liddy Shriver initiative. The Shriver family has for so many years, contributed so much to the Sarcoma Community in tribute to their daughter who was lost to Ewings Sarcoma. Their tireless work promoting research ideas and endeavors, and bringing together key researchers for each project for various sarcoma subtypes has been truly the definition of “proactive passion.” It goes without saying that they are highly respected by the medical research community. The National Leiomyosarcoma Foundation will receive updates on the inroads made from this recently co-funded LMS research project as well as other continuous updates on medical research efforts, clinical trials, and related youtube presentations through www.nlmsf.org. Additionally, your contribution to the website through your voice – adds hope for patients and families everywhere – your voice matters! We thank you all for you continued interest, support, and contribution to the efforts being made by foundations that honor you, represent you, and work tirelessly on behalf of the LMS Community.The link below is a briefing of the LMS research project – a brief summary of the initial ACOR announcement of this project in August and Sept. powerpoint Lisbon Portugal Briefing on the LMS Collaborative International LMS Research Project: updated-maximizing-therapeutic-response-in-leiomyosarcoma
