CHONDROSARCOMA- WITH MULTIMODAL THERAPY

ALTERNATE NAMES

Chondrosarcoma Grade III; Dedifferentiated Chondrosarcoma; Mesenchymal Chondrosarcoma

DESCRIPTION

Chondrosarcoma is the second most common form of bone cancer that primarily affects individuals over 40 years old, although it sometimes affects younger adults, adolescents, and children. It usually originates in the legs, arms, shoulder blades, ribs, pelvis, or pelvic bones, but may be found in any bone and sometimes outside of the bones (e.g., adjacent muscles). Chondrosarcoma with multimodal therapy indicates that the response to treatment has been poor and requires a combination of chemotherapy, surgery, and radiation therapy before or after surgery.

DIAGNOSTIC TESTING, PHYSICAL FINDINGS, AND ICD-9-CM/ICD-10-CM CODING

Diagnostic testing: Diagnostic testing for chondrosarcoma includes x-rays, computed tomography (CT) or magnetic resonance imaging (MRI) imaging to identify the tumor. A biopsy confirms the diagnosis.

Physical findings: Physical findings of chondrosarcoma vary, depending on the location and size of the tumor. Individuals may experience:

• •

  Pain; Swelling or a lump at the tumor site;

• •

  Unexplained weight loss;

• •

  Fatigue;

• •

  Difficulties breathing;

• •

  Fatigue; and

• •

  Fever or night sweats.

ICD-9: 170

ICD-10: C79.51

PROGRESSION

Chondrosarcoma usually begins as a single tumor. Spread (metastases) to other parts of the body is common if the disease progresses to grade III, dedifferentiated, or mesenchymal chondrosarcoma. Inoperable, unresectable, and metastatic chondrosarcomas have poor prognoses, with less than a third of individuals surviving five years.

TREATMENT

Surgery is the main treatment. Doctors may also use adjuvant chemotherapy if the cancer has spread. Recurrent chondrosarcoma may require surgery and radiation, and perhaps ablation treatments (e.g., liquid nitrogen or heating probes) to remove residual tumor.

SUGGESTED PROGRAMMATIC ASSESSMENT*

Suggested MER for Evaluation:

• •

  Report that specifies the type, extent, and site of the primary, recurrent, or metastatic lesion;

• •

  Biopsy or needle aspiration information found in operative notes, pathology reports, summaries of hospitalization or other medical reports that include details of the surgical and pathological findings;

• •

  Clinical history and examination that describes the diagnostic features of the impairment;

• •

  Imaging tests; and

• •

  Treatment records including surgical procedures, and up-to-date progress notes.
