Introduction • Concept of limb salvage surgery 25 years • 1970s adriamicyn & MTX • Ralp Marcove, Kenneth Francis & Hugh Watts limb salvage surgery technique
Introduction Today 90-95 % patient with extremity sarcoma who are treated at major centers specializing in musculoskeletal oncology can undergo limb-sparing surgery procedures
Introduction This dramatic alteration : 1. Improved understanding of tumor biology; 2. Effective induction chemotherapy; 3. Technical advances in surgical techniques; 4. Better characterization of the biomechanics of the human skeleton; 5. Advanced material engineering and manufacturing techniques; 6. The development of a reliable, stable modular prosthesis for reconstruction of the hip, shoulder, and knee.
Early Management & Referral • A successful limb salvage depends on : • A well - coordinated and timely series the first physician to see the patient • History and general examination • The basic work-up should include high quality plain radiographs for bone lesions.
Early Management & Referral Biopsy is not a part of the initial management of these lesions and is usually the last step in the work-up. The biopsy should be performed by the surgeon who will be doing the definitive surgery.
Work-up • Multidisciplinary team : • Orthopedic oncologist • Medical oncologist • Radiation oncologists • Musculoskeletal radiologist • Pathologist • Clinical psychologist • Social worker CLINICO PATHOLOGICAL CONFRENCE
Staging • The basic staging work : • High quality plain radiographs • Magnetic resonance imaging study of the entire tumor and nearby anatomic structures • Computed tomography scan of the chest • Whole body technetium bone scan • Biopsy of the tumor
Work-up The biopsy site must be carefully planned and located along so-called “limb—salvage lines”
Patient Education The patient and the patient’s family should be given the opportunity to participate in the decision
Indication • Every patient with a malignant tumor of the extremity should be considered for limb salvage. • The patient’s prognosis has a limited impact on the decision to perform limb salvage surgery. • In selected cases, limb salvage can be combined withmetastasectomy.
Indication • Minimum morbidity and rapid return to function. • Patients can enjoy relief from pain, improved quality of life, and intact body image that limb salvage can offer, even if they may not survive long-term.
Barriers Barriers to limb salvage include • Poorly placed biopsy incisions, • Major vascular involvement, • Incasement of a major motor nerve, • Pathological fracture of the involved bone, and others. • These adverse factors should not be viewed as absolute contraindications.
STAGES OF LIMB-SPARING SURGERY Limb-sparing procedure can be divided into five stages : • Neoadjuvant chemtherapy • Tumor resection must spare significant structures. • Stable, painless skeletal reconstruction • The surrounding and supporting soft tissue • Adjuvant chemotherapy
Surgical Resections and Reconstructions • The cornerstone of a limb salvage procedure is a complete resection of the tumor with an adequate margin. • Margins can be defined as intralesional, marginal, wide, and radical
Surgical Resections and Reconstructions • After completion of the tumor resection, the surgeon must reconstruct the resulting surgical defect. • The excised segment of bone must be replaced • Large internal prosthesis, • Segment of allograft bone, • Composite of an allograft and a prosthesis • Other methods.
Survival : 5 yaers survival rate 40 -70 %, • local recurrence : 5 -10 % • Immidiatete and Delayed Morbidity : increase revision • Function : better than amputation • Psycosocial Benefits : gooad early psycosocial adjustment
