In the uncommon circumstance of a patient not receiving adjuvant systemic therapy, there is no evidence suggesting that margins wider than no ink on tumor are needed. The DSWGs are comprised of experts in the following disease sites: gastrointestinal, melanoma/sarcoma, breast, hepatobiliary, endocrine/head & neck, colorectal and peritoneal surface malignancy. SSO believes that the information in this guideline, which has been endorsed by the American Society of Clinical Oncology (ASCO) and the American Society of Breast Surgeons (ASBS), can be used to decrease unnecessary margin re-excisions while maintaining excellent outcomes in breast conserving surgery and will serve as a definitive resource to the profession. 2010-2020. The Society of Surgical Oncology (SSO) Cancer Symposium 2021 will be held on 18-19 Mar 2021. A multidisciplinary consensus panel considered a meta-analysis of margin width and ipsilateral breast tumor recurrence (IBTR) from a systematic review of 33 studies including 28,162 patients as the primary evidence base for consensus. The use of no ink on tumor as the standard for an adequate margin in invasive cancer in the era of multidisciplinary therapy is associated with low rates of IBTR and has the potential to decrease re-excision rates, improve cosmetic outcomes, and decrease healthcare costs. METHODS The American Society of Clinical Oncology, American Society for Radiation Oncology, and Society of Surgical Oncology convened an Expert Panel to develop recommendations based on a systematic review of the literature and a formal … 2010-2020. To date, approximately one in three women who are treated surgically for DCIS undergo a re-excision, due in part to the lack of consensus on what constitutes an adequate negative margin. Lisboa, Portugal. Since BCT was established, the landscape of DCIS management has evolved with advances in imaging and pathologic evaluation, and the availability of adjuvant endocrine therapy, resulting in a decline in IBTR rates. 2020, Society of Gastrointestinal and Endoscopic Surgeons, Clinical Investigator Award (CIA) Criteria and Application Process, Young Investigator Award Criteria and Application Process.

With funding from the Susan G. Komen, a multidisciplinary panel of experts assembled in July 2013 to examine the evidence on the relationship between the amount of tissue removed surrounding a breast cancer, called a surgical margin, and ITBR. A 2010 survey found that 42 percent of surgeons recommended a two millimeter margin, while 48 percent favored larger margins. This prompted the Society of Surgical Oncology (SSO), in collaboration with the American Society of Radiation Oncology (ASTRO), to undertake an evidence based consensus to provide a clear and comprehensive approach for practitioners. Positive margins (ink on invasive carcinoma or ductal carcinoma in situ) are associated with a two-fold increase in the risk of IBTR compared to negative margins. There is no evidence that increased margin width nullifies the increased risk of IBTR in young patients.

More widely clear margins than no ink on tumor do not significantly decrease the rate of IBTR. These changes have resulted in a decreased rate of ipsilateral breast tumor recurrence (IBTR, also called local recurrence or in breast recurrence). Monica Morrow, MD . Surgical oncology is the branch of surgery applied to oncology; it focuses on the surgical management of tumors, especially cancerous tumors.. As one of several modalities in the management of cancer, the specialty of surgical oncology has evolved in steps similar to medical oncology (pharmacotherapy for cancer), which grew out of hematology, and radiation oncology, which grew out of radiology.
