New Delhi: Treating this aggressive condition in children and adolescents presents significant challenges due to its rapid progression and often late diagnosis. Traditional approaches, including surgery and chemotherapy, frequently result in severe side effects and a high risk of recurrence. However, recent advances in targeted therapies, immunotherapy, personalized medicine, and surgical techniques offer new hope. These innovations aim to improve survival rates and quality of life for young patients, marking a promising shift in the management of this formidable illness.
In an interaction with News9Live, answered all FAQs about osteosarcoma in children and also listed the challenges and advances in treatment. DR. Shantanu Pendse, MD,DM, Consultant – Medical Oncology, HCG Cancer Centre, Nagpur.
Osteosarcoma is the most common type of bone cancer in children and adolescents, predominantly affecting the long bones in the legs and arms. This aggressive malignancy poses significant challenges in both diagnosis and treatment due to its rapid growth and tendency to metastasize.
Challenges in Treatment
One of the primary challenges in treating osteosarcoma is early diagnosis. Symptoms such as pain and swelling are often mistaken for sports injuries or growing pains, leading to delays in seeking medical attention. By the time osteosarcoma is diagnosed, it is frequently at an advanced stage, complicating treatment efforts.
Osteosarcoma cells can be highly resistant to conventional chemotherapy, and there is a significant risk of recurrence after initial treatment. The development of multi-drug resistance mechanisms within cancer cells often renders standard therapies less effective over time, necessitating more aggressive and varied treatment approaches.
The standard treatment protocol for osteosarcoma includes a combination of surgery and chemotherapy. While this approach can be effective in eradicating the primary tumor, it often comes with severe side effects. Chemotherapy can cause long-term health issues such as cardiotoxicity, nephrotoxicity, and secondary cancers. Surgical interventions, especially limb-salvage surgeries, may result in physical limitations and impact the child’s quality of life.
Advances in Treatment
Targeted Therapies: Recent advances in molecular biology have paved the way for targeted therapies, which aim to attack specific cancer cell pathways without harming normal cells. Drugs like sunitinib and pazopanib, which block enzymes that promote cancer cell growth, are showing promise in clinical trials. These therapies offer the potential for more effective treatment with fewer side effects compared to traditional chemotherapy.
Immunotherapy: Immunotherapy is an emerging field that harnesses the body’s immune system to fight cancer. Immune checkpoint inhibitors, such as nivolumab, enhance the body’s immune response against cancer cells and are being explored in combination with other treatments for osteosarcoma. Early studies indicate that immunotherapy could significantly improve outcomes for children with osteosarcoma by preventing recurrence and targeting metastatic cells.
Personalised Medicine: The advent of personalised medicine allows for treatments tailored to the individual genetic makeup of the patient and their tumour. By analysing the genetic profile of the tumor, oncologists can identify specific mutations and tailor therapies that directly target these aberrations. This approach not only improves the efficacy of treatment but also minimises unnecessary exposure to toxic drugs.
Advanced Surgical Techniques: Improvements in surgical techniques and prosthetic design have significantly enhanced the outcomes of limb-salvage surgeries. Advances in imaging technology and surgical planning allow for more precise tumor removal while preserving as much healthy tissue as possible. Customisable prosthetics and bioengineered grafts are also being developed to improve functionality and cosmetic outcomes for pediatric patients.
Conclusion
The treatment of osteosarcoma in children remains fraught with challenges, including late diagnosis and the severe side effects of traditional therapies. However, recent advancements in medical research and treatment techniques offer new avenues for improving patient outcomes. Innovations in targeted therapies, immunotherapy, personalised medicine, and advanced surgical procedures hold promise for better survival rates and enhanced quality of life for affected children. Continued research and development are essential to fully realize the potential of these advancements and provide hope for young patients and their families.
