This study analyzed 24 metastatic bone tumor cases over 6 years. Most occurred in middle-aged adults, primarily affecting the axial skeleton, with lung, breast, and colon cancers being common origins.

Area of Science:

  • Oncology
  • Skeletal Metastasis Research

Background:

  • Metastatic bone tumors represent a significant clinical challenge.
  • Understanding the demographics and primary origins of bone metastases is crucial for patient management.

Purpose of the Study:

  • To characterize the epidemiological features of metastatic bone tumors.
  • To identify common primary sites and skeletal locations of metastases.
  • To determine the frequency of bone metastasis as an initial presentation of malignancy.

Main Methods:

  • Retrospective analysis of 24 cases of metastatic bone tumors over a 6-year period.
  • Data collection included patient demographics, skeletal site of metastasis, and primary tumor origin.
  • Review of diagnostic investigations to determine initial disease manifestation and primary tumor detection.

Main Results:

  • The majority of cases (70.8%) occurred between the 4th and 6th decades of life, with a slight male predominance.
  • The axial skeleton was involved in 62.5% of cases, most commonly the spine.
  • Adenocarcinomas constituted a large proportion (62.5%), with lung, breast, and large intestine as the most frequent primary sites.
  • Bone metastasis was the initial manifestation in 41.7% of patients.
  • The primary tumor remained undetected in 20.8% of cases despite thorough investigation.

Conclusions:

  • Metastatic bone tumors predominantly affect middle-aged adults and frequently involve the axial skeleton, particularly the spine.
  • Lung, breast, and colorectal cancers are the leading causes of bone metastasis.
  • Bone metastasis can be the first sign of an unknown malignancy, highlighting the importance of skeletal surveys in diagnosis.
