Cancer Therapies

8.1K
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...

Spongy Bone01:09

Spongy Bone

12.8K
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...

Rous Sarcoma Virus (RSV) and Cancer

5.2K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Bone Disorders

7.9K
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

3.8K
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...

Summary

Osteosarcoma is a type of bone cancer primarily affecting long bones, with a bimodal age distribution. This overview covers its clinical presentation, diagnosis, and treatment options for this rare cancer.

Area of Science:

  • Oncology
  • Orthopedic Oncology

Background:

  • Osteosarcoma is a primary malignant bone tumor.
  • It predominantly affects adolescents and young adults, with a secondary peak in older adults.
  • This condition typically arises in the long bones, such as the femur and tibia.

Purpose of the Study:

  • To provide a comprehensive overview of osteosarcoma.
  • To detail the clinical manifestations and diagnostic approaches.
  • To outline current treatment strategies for osteosarcoma.

Main Methods:

  • Literature review of osteosarcoma cases.
  • Analysis of clinical presentation and diagnostic imaging.
  • Summary of treatment modalities including surgery, chemotherapy, and radiation therapy.

Main Results:

  • Osteosarcoma presents with bone pain, swelling, and sometimes pathological fractures.
  • Diagnosis relies on imaging (X-ray, MRI, CT) and biopsy.
  • Treatment is multimodal, aiming for limb salvage and oncologic control.

Conclusions:

  • Early diagnosis and prompt, multidisciplinary treatment are crucial for improving outcomes in osteosarcoma.
  • Understanding the bimodal age distribution aids in clinical suspicion.
  • Ongoing research focuses on targeted therapies and improving survival rates.
