International Sentinel Node Society 

The purpose of the International Sentinel Node Society (ISNS) is to serve and coordinate the needs of the diverse community of physicians and scientists who study the sentinel node. The Society is a non-profit corporation. Active Membership in the Society is limited to surgeons, pathologists, nuclear medicine physicians, dermatologists, oncologists, radiotherapists, and scientists who have shown evidence of continuing commitment to sentinel node surgery as demonstrated by such activities as:

  1. Oncologic teaching or research
  2. Involvement in activities of a National or International Oncology Research Society

The International Sentinel Node Society is encouraging the collaboration and cooperation of oncologists, surgeons, pathologists, and nuclear medicine physicians from all over the world in researching the effects of sentinel node surgery and lymphatic mapping techniques.

Sentinel Node Oncology Foundation 

The Sentinel Node Oncology Foundation (SNOF) is a non-profit foundation that recruits medical institutions to participate in the Sentinel Lymph Node Working Group (SLNWG); the SNOF Statistics Center (SNOFSC) collects and manages cancer clinical data from SLNWG members.

The mission of the SNOF is to advance the care and treatment of patients with solid cancers and to help develop new preventative strategies, diagnostics, and treatments.

With advancements in cancer care and treatment, cancer survivors today live longer and enjoy a vastly improved quality of life than thought imaginable. Recent discovery has found that the sentinel lymph node in the body is the gateway for cancer to spread. Therefore, the SNOF was created in 2003 on the premise that the next level of cancer research and treatment is to understand more about this important gateway. It is now known that the same type of cancer is different from one person to the other. The genetic signature of cancer of each patient may be determined so that treatment can be tailored to each cancer patient more precisely and efficiently. The SNOF is building a robust sentinel lymph node databank so that the natural history of patients with solid cancer can be accurately defined by their genetic profiles. The SNOF has unified cancer specialists working together through the SLNWG to reach its goals through research and clinical trials. The SNOF has more than 50 members and has collected research data from more than 5,000 patients to date, making our database one of the largest multicenter databases in the sentinel lymph node era.

The SNOF is currently in the process of analyzing numerous data points that might lead to information that can aid in determining the chances of survival for different patients diagnosed with cancer. This would lead to more precise treatment recommendations and the avoidance of severe toxic effects from over-treatment.

Tree of Medicine

Sentinel node surgery has changed the landscape of surgical oncology. A phenomenal amount of data has been reported with more than 4000 (!!) articles published on breast cancer sentinel nodes alone. To manage this huge and growing body of literature, a team at The Tree of Medicine has developed a web application that supports analysis, communication and dissemination of this published data.

Through support of the Tree of Medicine and in cooperation with the Joint International Oncology (Sentinel Node and Cancer Metastasis) Congress, attendees of the Congress will receive a free one year subscription to the Tree of Medicine’s Sentinel Nodes and Breast Cancer database. Subscribers will gain access to the “Tree”, which contains organized descriptions of more than 4000 citations related specifically to sentinel nodes and breast cancer. Each month, subscribers will stay up to date with a feed of all new articles in the field. A short list of expert summaries have been completed, and subscribers are invited to request additional summaries on timely topics of their interest. Subscribers may readily store all of their full text PDFs for sharing with their group.

With Sentinel Nodes and Breast Cancer as the premiere module, this system was designed to change how we manage the massive amounts of literature on important medical topics. We invite your participation and that of your fellows, residents and students. The Tree is an outstanding starting point for the preparation of new publications and sharing of information.

A table will be available at the meeting for instruction and signups, or you can sign up now at

We look forward to seeing you there!
