Reconstruction

• Allograft and/or Prosthetic reconstruction for skeletal defects in bone sarcomas

1990 – Present1990 – Present

What progress has been made

in the last 15 years when compared to 1975-1990?

• Surgery – skeletal reconstruction on allograft vs.

prosthetic replacement for bone sarcomas

• Radiation Therapy for Soft Tissue Sarcomas– pre-op vs. post operative RT

• Medical Oncology for Bone Sarcomas– dose intensity– combination changes

Mission:Mission: ……to advance the care of patients with connective

tissue tumors and to increase knowledge of all aspects of the biology of these tumors, including basic and clinical research. .

CTOS & MSTS: Similar Missions

Founded 1993-1994 Multidisciplinary membership400 members from 30 countries

CTOS & MSTS: Similar Missions

Mission:

…to advance the science of orthopaedic oncology and to promote high standards of patient care. It does this through excellence in education and research and through advocacy on behalf of patients and orthopaedic oncologists.

MSTS & CTOS Should Consider: • Collaborating• Uniting• Merging

If both patients and members are our constituency than….

MSTS Presidential Address

1992-1993 (M.A. Simon)

• Society too small

• Not multidisciplinary

CTOS Formed 1993-1994

• MSTS remained primarily an orthopaedic surgery society

•1993-1994 Suit forms CTOS

• Interesting confluence

Barriers to CTOS / MSTS Barriers to CTOS / MSTS CollaborationCollaboration

• Leadership (Executives and Committees)

• Leadership changes & personal dynamics within organization

• Members • Differences in resources

• Name/Identity

Accomplish Vision & Mission of CTOS / MSTS

• Constant meeting of leadership

• Have adjacent meetings

CTOS / MSTS collaboration is best for CTOS / MSTS collaboration is best for our patients our patients andand members members

One day the vision of Dr. Suit and patients will be realized…
