Cancer Therapies

7.9K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Bone Formation by Endochondral Ossification01:24

Bone Formation by Endochondral Ossification

5.0K
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...

Bone Disorders

3.8K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

3.1K
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...

Bone Cells and Tissue01:30

Bone Cells and Tissue

5.1K
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...

Spongy Bone01:09

Spongy Bone

4.9K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

Summary

Survivors of pediatric cancers face a risk of secondary osteosarcoma (SOS). This study details SOS patient characteristics and outcomes, showing survival rates are lower than primary osteosarcoma but warrant specialized care.

Area of Science:

  • Oncology
  • Pediatric Oncology
  • Sarcoma Research

Background:

  • Secondary osteosarcoma (SOS) is a known risk for pediatric cancer survivors.
  • Understanding SOS clinical characteristics and outcomes is crucial for improving patient care.

Purpose of the Study:

  • To examine the clinical characteristics of patients who developed secondary osteosarcoma (SOS).
  • To evaluate the outcomes and survival rates for patients diagnosed with SOS after primary cancer treatment.

Main Methods:

  • Retrospective analysis of 26 pediatric cancer survivors diagnosed with SOS.
  • Review of treatments for primary neoplasms (PN), including chemotherapy and radiotherapy.
  • Analysis of SOS diagnosis timing, sites, treatment modifications, and survival data.

Main Results:

  • Median time to SOS diagnosis was 7.3 years post-primary neoplasm (PN).
  • High incidence of SOS at unfavorable sites (hip, skull).
  • 5- and 10-year overall survival rates were 50% and 38.9%, respectively.

Conclusions:

  • Survival rates for SOS are lower than primary osteosarcoma but significant.
  • Multidisciplinary referral center management is essential for optimizing cure and quality of life for SOS patients.
