Presentation
Symptoms of osteosarcoma are dependent on the location of the tumor [7]. However, some of the most common presentations include limitation of motion of joints, limping, redness, swelling, bone fractures, bone pain following any form of movement or exertions on the extremities.
The pain experienced varies from one patient to the other. Some stop feeling pains when the joint is at rest while for others, the pains continue even when fully at rest leading to sleep deprivation in some cases. When any of these presentations are visible the muscle in the affected limb will feel smaller than those in the opposite limb.
Entire Body System
- Swelling
A 21-year-old man of African descent presented to our center complaining of shortness of breath, awareness of heart beats, easy fatigability, swelling of lower limbs, and left-side chest discomfort for the past 6 months getting worse for the last 3 months [ncbi.nlm.nih.gov]
Often, there is a firm swelling or lump in the area of the pain. This swelling is caused by the tumor growing inside the bone. If the cancer is in a leg bone, the person may limp. [familydoctor.org]
Pain and swelling are the most common presenting symptoms. Although it can occur at any age, it usually affects patients in the second and third decade of life with a peak incidence between 13 and 16 years of age. [bestpractice.bmj.com]
Lameness, swelling and rapid metastasis to the lungs are usual features. [medical-dictionary.thefreedictionary.com]
- Fever
In children without fever and vomiting, antibiotics are not given unless the child’s symptoms have not resolved within 2 days, or unless the child is less than 2 years of age. In children with fever and vomiting, antibiotics are generally given. [healthengine.com.au]
However, you should seek medical treatment if pain persists or you have a fever. There are two types of middle ear infections: acute otitis media (AOM) and otitis media with effusion (OME). [healthline.com]
Major symptoms include pain (intermittent at first, later severe and constant), swelling, limitation of joint motion, a high frequency of fractures, and eventually fever and general debilitation. [britannica.com]
Fluid and mucus become trapped inside the ear, causing the child to have a fever and ear pain. Otitis media with effusion. Fluid (effusion) and mucus continue to accumulate in the middle ear after an initial infection subsides. [hopkinsmedicine.org]
- Weight Loss
Unintended weight loss – some people experience weight loss due to the body’s reaction to the cancer. [limbpreservation.org]
Systemic symptoms, such as fever and weight loss, occur rarely in the absence of very advanced disease. Epidemiology Osteosarcoma has a bimodal age distribution with the first peak in the second decade of life and the second among older adults. [curesarcoma.org]
- Weakness
The low staining (1+) was classified as the p62 weak group (50.6%), the medium staining (2+) and intense staining (3+) were classified as the p62 strong group (44.3%). [ncbi.nlm.nih.gov]
Side effects of radiation therapy include skin burns, rashes, weakness, nausea, loss of hair etc. [news-medical.net]
Strong staining was observed (score 3+) in 34.4%; while 21.9% showed moderate staining (score 2+); and 21.9% displayed weak staining (score 1+), on the other hand, no staining was detected in 7 out of 32 cases (21.9%) (score 0). [researchgate.net]
The tumor may cause weakness in the affected area of the bone. A fracture at the site of the tumor is called a “pathological fracture,” which occurs after what often seems like a routine movement. [hopkinsmedicine.org]
- Localized Pain
We present the case of a 22-year-old girl with increasing local pain in the distal left thigh. The patient was initially diagnosed as bone cancer according to computed tomography (CT) and X-ray imaging. [ncbi.nlm.nih.gov]
Signs and Symptoms of Osteosarcoma Pain – the pain experienced with an osteosarcoma is typically in the area of the tumor, which is often called local pain. Swelling - there may be inflammation in the area of a tumor leading to swelling. [limbpreservation.org]
The pain may be present for several weeks to several months.[1]The majority of patients with osteosarcoma present with localized pain at the primary tumor site.[3] Range of motion may also be limited as the tumor encroaches upon the joint space.[1] The [physio-pedia.com]

Musculoskeletal
- Bone Pain
Herein, we presented a 50-year-old man patient who visited hospital due to local bone pain in the left leg. He was initially diagnosed with osteoblastic osteosarcoma. [ncbi.nlm.nih.gov]
Common signs of this type of cancer include: bone pain (in motion, at rest, or when lifting objects) bone fractures swelling redness limping limitation of motion of joints How bone pain is experienced may vary. [healthline.com]
However, it can occur in any bone. The first symptom is usually bone pain near a joint. This symptom may be overlooked because of other more common causes of joint pain. [nlm.nih.gov]

The median volume was 272 cm3 (range, 5 to 4,212 cm3), calculated using the ellipsoid formula.13 In three patients, we could not calculate the volume because radiologic imaging was not available (withdrawn by the patients). [ascopubs.org]
Workup
There are different medical procedures that aid in the diagnosis of osteosarcoma [8]. Physical examination is needed to establish swelling and redness. Medical history is vital to see previous illnesses and medical treatments that may suggest the presence of an etiologic factor. A blood test may be used to check for the presence of tumors. Other tests that can be carried out include a CT scan, MRI, X-ray, PET scan, biopsy and bone scan. All of these will demonstrate the presence of osteosarcoma.

Treatment
Generally, osteosarcoma is treated with the aid of a combination of therapies [9]. This can include chemotherapy, radiation therapy and surgery. Before surgery, patients with high grade tumors are subjected to neo-adjuvant therapy.
Surgery involves the removal of tumor with a wide margin. The goal of this is to leave the area free of all disease.
Majority of tumors at the bones and joints can now be removed safely without losing the limb affected. To replace tissues removed during the surgery, a surgeon can use a metal implant, an allograft a combination of both or bone removed healthy areas of the body.
After a successful surgery, a pathologist should examine the necrosis rate of the osteosarcoma [10]. It is the indicator of how well the tumor is responding to chemotherapy. Drugs are chosen for additional chemotherapy treatment based on this necrosis rate. This additional chemotherapy lasts six months on average.
Prognosis
When the disease is localised and metastasis hasn’t ensued, there is a long term survival rate of 70 to 75% [6]. However as soon as metastasis sets in, prognosis is negative and survival rate drops to 30% especially if the metastasis affects the lungs.
Etiology
There have been many studies aimed at the etiologic factor responsible for osteosarcoma. However, it is still unclear, what actually leads to osteosarcoma. An etiologic factor is only seen in around 15% of cases [3].
Some of the etiologic factors that have been identified till date include:
- Radiotherapy: Radiation treatment for cancer can lead to a damage of the DNA in bone cells.
- Underlying bone abnormalities: One good example of a disorder that can lead to the development of osteosarcoma is Paget disease.
- Genetic factors: Genes for osteosarcoma can be inherited from a parent and this increases the possibility of the condition developing.
Epidemiology
Osteosarcoma is among the top 8 forms of childhood cancer. It makes up 2.4% of all malignancies in pediatric patients and around 20% of all cases of primary bone cancers [4]. In the United States, the incidence of the condition in patients aged 20 and below is placed at 5.0 cases per million each year in a general population. However the incidence varies slightly when ethnicity is considered. In blacks, incidence is 6.8/million, in Hispanics it is 6.5/million and in white ethnicities it is 4.6 per million each year.
The condition is seen more in males than in females with incidence placed at 5.4 per million and 4.0 per million respectively.
It originates more frequently in the metaphyseal region of tubular long bones. 42% of cases is seen in the femur, 19% is seen in the tibia and 10% in the humerus. Around 8% of all cases happen in the skull and jaw and another 8% is seen in the pelvis.
Pathophysiology
Osteosarcoma arises when there is a malignant growth of the bone cells that are responsible for the production of the hard boney matrix [5]. This malignant growth is what forces the cell to grow into a cancerous tissue or tumor. The bone cells that are seen in the tumor retain their bone like functions by growth and division. This explains how they are able to spread to other areas of the body.
Prevention
Osteosarcoma cannot be prevented.
Summary
Osteosarcoma is the most common type of bone cancer [1]. It is seen mostly in children and teenagers as it generally involves the long bones near metaphyseal growth plates. It is possible for older adults to develop this condition but the vast majority of patients are aged 6 to 25. Teenagers develop this type of bone cancer the most and males develop it more than females. This phenomenon may be as a result of the fact that bones grow at a very fast rate for boys.
The cancer often develops in the bones of the legs and arms but most cases of it originate around the ends of the long bones which make up the knee [2]. When left untreated, osteosarcoma can spread to virtually any part of the body. The lungs and other bones are the most common metastasis sites for osteosarcoma.
Patient Information
Osteosarcoma is a cancer of the bone. It is mostly seen in the long bone in the legs in people younger than 20 years of age. However, it can arise in just about any bone in any part of the body. The cancer, if left untreated can spread to other organs of the body.
The chances of recovery from this type of cancer are high as long as the condition gets discovered early enough. Treatment is by surgery and use of chemotherapy primarily.
