Metastasis02:30

Metastasis

5.8K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Tumor Progression02:07

Tumor Progression

6.6K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Cancer02:18

Cancer

50.7K
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

3.4K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

The Tumor Microenvironment02:17

The Tumor Microenvironment

7.0K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Bone Cells and Tissue01:30

Bone Cells and Tissue

6.4K
Bones contain a relatively small number of cells entrenched in a matrix of organic and inorganic components. Although bone cells compose only a small amount of the bone volume, they are crucial to its function. Four types of cells are found within the bone tissue— osteoblasts, osteocytes, osteogenic cells, and osteoclasts.
Osteoblasts and Osteocytes
The osteoblast is the bone cell responsible for forming new bone tissue. It is found in the growing portions of bone, including the...

Summary
This summary is machine-generated.

Bone metastases are common in older adults, primarily from breast, lung, and prostate cancers. Early detection of bone pain is crucial, as many patients present with fractures.

Area of Science:

  • Oncology
  • Orthopedics
  • Radiology

Background:

  • Metastasis is the spread of cancer cells from the primary tumor to distant organs.
  • Bone metastases commonly arise from breast, prostate, and lung cancers, typically in individuals over 50.
  • The axial skeleton is the most frequent site for bone metastasis.

Purpose of the Study:

  • To determine the incidence of various tumors causing bone metastases within a specific healthcare institution.

Main Methods:

  • An observational, cross-sectional, and descriptive study design was employed.
  • Retrospective analysis of patient cases diagnosed with bone metastases was conducted.

Main Results:

  • The study included 193 patients (121 women, 72 men) aged 42-84.
  • Breast, lung, and prostate cancers were the most frequent primary tumors. Other contributing cancers included cervical and renal.
  • The axial skeleton (lumbar and dorsal spine) and appendicular skeleton (femur, humerus) were most affected.
  • Timely detection strategies remain challenging; bone pain warrants a tumor suspicion protocol.

Conclusions:

  • Over 80% of patients presented with fractures, indicating delayed diagnosis.
  • All patients experienced prolonged pain (over 12 months) without a preceding diagnostic protocol for tumor suspicion.
