Chondrosarcoma Specialist Surgeon Singapore

Surgical Management of Cartilaginous Malignancy and Reconstruction 

We manage chondrosarcoma as a relentless challenge of surgical margins and structural restoration. Under the clinical direction of Dr. Saminathan Suresh Nathan, our approach centers on the reality that these tumors are predominantly chemo-resistant, necessitating radical, wide oncological resections. By utilizing thirty years of surgical discernment—integrating 3D-planned resections, megaprostheses, and custom biological grafts—we focus on achieving clearance while preserving the functional endurance of the human frame. Chondrosarcoma are a common malignant solid tumor of bone especially in Grade I forms. The grade II and II tumors are rare. They typically happen in the fourth and fifth decades of life. Treatment involves the use of surgery with or without cryotherapy. Radiation and chemotherapy is not usually necessary.

Surgical Considerations

• Oncological Margin Verification: Precise execution of wide resections to manage radio-resistant and chemo-resistant cartilaginous matrices.

• Anatomical Reconstruction: Utilization of custom-engineered pelvic and long-bone implants to restore weight-bearing mechanics after radical excision.

• Joint Preservation: Assessment of joint-sparing resections when tumors are localized to the metaphysis, ensuring long-term articular integrity.

Figure 1. Five-year survival rates of chondrosarcoma are generally good at about 80%. This tumor exists in three grades with the poorer grades being responsible for the 30% fatalities seen above. Furthermore, the lower grade tumors can degrade "de-differentiate" into higher grades and it is important to remove them early and totally because of this.

Figure 2. Some of the worse challenges come with the higher grade of chondrosarcoma mainly because they do not respond to chemotherapy or radiation. Therefore the only recourse is to surgery. Occasionally, limb salvage is possible even in the very large tumors but the risk is very high. This patient had a neglected chondrosarcoma of the pelvis which was resected and reconstructed with a cadaveric bone transplant.
