Functional outcomes of bony sarcoma (BS) in Adolescent and Young Adult Oncology (AYAO) patients-a scoping review
1Department of Medical Oncology, National Cancer Centre Singapore, Singapore, Singapore.
Background:
Sarcomas are heterogeneous rare cancers, and while they affect 1% of all adult cancers, they affect 10-20% of adolescents and young adults (AYAs). The 5-year survival rates range between 50-60% but have remained stagnant. While the management of bony sarcomas (BS) usually involves systemic treatment and major morbid surgeries, functional outcomes and quality of life have been largely overlooked.
Methods:
A literature search was conducted on PubMed and ScienceDirect using key search terms of "Adolescent and young adult", "AYAO", "bone sarcoma, osteosarcoma, Ewing sarcoma", "functional outcomes" and "health-related quality of life" from 1st January 2003 to 13 March 2023. A total of 858 results in total were screened by two independent authors, and 18 selected papers were included in the scoping review.
Results:
AYAs have poorer outcomes in all aspects-physical, social and psychological in BS survivorship, as many changes from disease and treatment are usually persistent and irreversible, with significant impact on mobility, function and body image. Current tools to assess health-related quality of life (HRQoL) in AYAs are not standardized or validated in this age group. Subjective tools measuring physical outcomes do not correlate to objective measures of physical function.
Conclusions:
These outcomes have a direct connection to their independence, self-confidence and future job endeavors, yet hardly any specific research has gone into it. They are stricken with a cancer diagnosis during the prime of their lives and it is essential to manage them holistically to preserve and maximize their functional outcomes. More research is required to monitor their outcomes long-term post-treatment and into survivorship.

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

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...
01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.
Cartilage, a semi-rigid connective tissue found in regions such as...
