Dr. Osborne’s research has spanned 40 years both in the laboratory and clinically in the United Kingdom and the United States of America.
During his years in the United Kingdom at Charing Cross Hospital and Medical School, and the Royal Marsden Hospital / Institute for Cancer Research in the 1970s, he studied the spread of breast cancer to the lymph nodes describing, in 1978, the uptake of a radioactive tracer by the primary regional lymph node(s), now called the sentinel lymph node(s). He correlated the lymph nodes with their histopathology to determine whether the breast cancer had spread to the lymph nodes in patients with operable breast cancer. His thesis and publications led to a Master of Surgery degree (PhD equivalent) from the University of London.
During his tenure as Lecturer in Surgery at the Royal Marsden and Institute for Cancer Research Dr. Osborne also studied breast conserving surgery and radiation therapy for breast cancer, which was published in the premier journal Cancer Dr. Osborne became convinced that this type of treatment would come to replace mastectomy for the majority of women with early stage breast cancer.
In the Unites States in the 1980s at Memorial Sloan Kettering Cancer Center Dr. Osborne offered patients with early stage breast cancer breast conserving surgery with radiation therapy. He believed that better surgical technique and modern radiation therapy would yield significantly better results than those obtained between the 1950s to the 1970s.
As Head of the Breast Cancer Research Laboratory, Dr. Osborne conducted both laboratory and clinical studies relating to the detection of the spread of breast cancer in the body (bone marrow).
At Memorial Sloan Kettering Cancer Center Dr. Osborne initiated a Special Surveillance Program for women at increased risk of breast cancer. His interest in the causes of breast cancer led to his joining the Biochemical Endocrinology Laboratory at the Rockefeller University where he studied the relationship between hormones and breast cancer initiation and promotion in order to develop novel strategies for prevention.
Subsequently as Chief of the Breast Service at the New York Hospital and Professor of Surgery at Cornell University Medical College in the 1990s Dr. Osborne continued his clinical research into bone marrow micrometastases in women with early stage breast cancer.
At the Strang Cancer Research Laboratory at Rockefeller University his research continued into the hormonal initiation / promotion of breast cancer and the development of novel strategies for prevention.
Since 2000 Dr. Osborne has devoted his time to Strang developing guidelines for early detection through cancer screening and best practices for prevention.
Dr. Osborne has been fortunate to work over the years with remarkable scientists and physicians, in collaborative teams, without whom this work could not have been accomplished and who are acknowledged at the end.
The Spread of Breast Cancer to the Lymph Nodes
Dr. Osborne conducted laboratory experimental studies at Charing Cross Hospital / Medical School to optimize the uptake of a ratio-active tracer (99m Tc) encapsulated in liposomes. This work was translated to women with breast cancer, both at Charing Cross Hospital / Medical School and the Royal Marsden Hospital / Institute for Cancer Research. This resulted in mapping the primary regional lymph node and correlating them with the spread of breast cancer. The development of hand held probes to detect radioactivity in lymph nodes lead to the current technique of identifying the sentinel node(s) during surgery.

Breast Conserving Surgery and Radiation Therapy for Early Stage Breast Cancer as an Alternative to Mastectomy
In 1983, while at Memorial Sloan Kettering Cancer Center, Dr. Osborne presented the largest and longest follow up series of patients with breast cancer treated at the Royal Marsden Hospital, between the 1950s to the 1970s, by breast conserving surgery and radiation therapy to the 36th Annual Meeting of the Society of Surgical Oncology in a paper entitled Early breast cancer: 20-year follow-up of breast conservation. These data were published in the journal Cancer in 1984.
In his book The Breast Cancer Wars Baron Lerner MD, a Professor at the Mailman School of Public Health at Columbia University, described the obstacles surrounding Dr. Osborne’s introduction of breast conserving surgery as an alternative to Memorial Sloan Kettering Cancer Center’s policy of mastectomy for patients with early stage breast cancer.
The Breast Cancer Wars. Hope, Fear, and the Pursuit of a Cure in Twentieth-Century America Baron L. Oxford University Press 2001; pp. 254-255
Breast conserving surgery is now the standard of care for the majority of women with breast cancer. Following the slow acceptance of breast conserving surgery Dr. Osborne continued to be active in research to refine the technique and the surgery required in the event of recurrence. Today about 5% of patients experience a recurrence and for a highly selected group a second chance for conservation may be considered; further research is ongoing to determine whether this is a safe option.

Bone Marrow Micrometastases in Early Stage Breast Cancer
During his time as head of the Breast Cancer Research Laboratory at Memorial Sloan Kettering Cancer Center, Dr. Osborne studied the spread of breast cancer outside of the breast and lymph nodes to the bone marrow. Before surgery began, after the patient was anesthetized, samples of the bone marrow were taken and tested for cancer cells using, for the first time, monoclonal antibodies against components in cancer cells which are not found on bone marrow cells.

Women at Risk for Breast Cancer
In the early 1980s Dr. Osborne started a Special Breast Surveillance Program at Memorial Sloan Kettering Cancer Center specializing in the care of women at increased risk for breast cancer. The women in this program had never had breast cancer and the majority had a strong family history of breast cancer; some women had breast biopsies that showed a tissue change indicating an increased risk in the future. In 2004 the BRCA1 gene was discovered and Dr. Osborne and his co-investigators contributed DNA from the largest group of women at risk due to a family history consistent with the Breast Ovarian Cancer Syndrome and were co-authors of the first BRCA1 clinical paper published. Dr. Osborne joined the Hereditary Breast Cancer Clinical Study Group in the late 1990s. He has maintained a clinical and research interest in women at enhanced risk for breast cancer over the past 30 years.

Hormones and Breast Cancer
Dr. Osborne’s interest in hormones and breast cancer was fostered by his joining the Biochemical Endocrinology Laboratory at the Rockefeller University soon after joining the staff of Memorial Sloan Kettering Cancer Center in the early 1980s. The research focuses on the cellular and molecular biological changes in the process of cancer development. The Rockefeller University group hypothesized that a specific metabolite of estrogen was a potential initiator and promoter of breast cancer. Dr. Osborne and his colleagues showed that production of this specific metabolite was increase 500 fold in the breast tissue of women with breast cancer compared to women without breast cancer. This work prompted the author of a book entitled Breakthrough: The Race to Find the Breast Cancer Gene by Kevin Davies PhD, Editor of a leading journal in the field - Nature Genetics, to describe Dr. Osborne’s work.

The role of this specific estrogen metabolite remains controversial but there has been a growing body of evidence supporting this hypothesis. This work led Dr. Osborne’s research group to develop strategies for prevention.

Prevention of Breast Cancer
Dr. Osborne has maintained an interest in breast cancer prevention studying the effects of various pharmaceutical, nutriceutical and botanical agents’ ability to inhibit or reverse pre-cancer or cancer development. He was Principal Investigator at Strang as a collaborator in studies by the National Surgical Adjuvant Breast and Bowel Project (NSABP) on the risk reducing effects of tamoxifen and raloxifene which showed the risk of breast cancer can be reduced by half in women at increased risk.

Cancer Screening and Prevention
Dr. Osborne has developed, with cancer specialists, comprehensive guidelines for cancer screening and best practices for prevention which are available at www.strang.org. The guidelines are directed towards Primary Care, Family Practice, Gynecology, Internal Medicine and other Health Care Providers.
The guidelines also provide comprehensive answers to the most frequently asked questions (FAQs) by patients who have been recommended breast, cervical, colon, lung and prostate cancer screening. Dr. Osborne is planning for Strang to partner with major health care systems to provide them with a unified and comprehensive program for their physicians and allied health care professionals.
Dr. Osborne is also collaborating in a study of Primary Care Physicians cancer screening recommendations and their patients understanding of the recommendations in order to develop easier and more effective methods for cancer screening recommendations.
Dr. Osborne acknowledges and thanks all those with whom he has had collaborations which have largely made this work possible.
Some of Dr. Osborne’s collaborators have worked with him for over 30 years such as Nitin Telang PhD, Leon Bradlow PhD, George Wong PhD, and Charles Potter MA.
