    Summary
    This summary is machine-generated.

    Chordoma, a rare bone cancer, occurred at low incidence in Finland between 1953-1971. This study highlights high metastasis rates and poor survival outcomes for chordoma patients.

    Area of Science:

    • Oncology
    • Epidemiology
    • Pathology

    Background:

    • Chordoma is a rare bone tumor arising from notochordal remnants.
    • Understanding its incidence, characteristics, and outcomes is crucial for patient management.

    Purpose of the Study:

    • To analyze the incidence, tumor characteristics, treatment, and survival rates of chordoma in Finland.
    • To compare observed metastasis rates with existing literature.

    Main Methods:

    • Retrospective analysis of 20 chordoma cases reported to the Finnish Cancer Registry from 1953-1971.
    • Data collection on patient demographics, tumor location, treatment, recurrence, metastasis, and survival.

    Main Results:

    • A total of 20 chordoma cases were identified, with a higher incidence in males (0.30/10^6) than females (0.18/10^6).

  • Sacral tumors were most common (15 cases), followed by vertebral (3) and cranial (2).
  • Distant metastases occurred in 60% of cases, exceeding typical literature reports, with 5-year and 10-year relative survival rates of 35% and 18%, respectively.

    • Conclusions:

    • Chordoma incidence in Finland during the study period was low, with a male predominance.
    • The high rate of distant metastases and poor survival underscore the aggressive nature of this tumor.
    • Combined surgery and radiotherapy were the primary treatment modalities, yet survival rates remain suboptimal.
