Tumor Immunotherapy01:27

Tumor Immunotherapy

880
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Cancer Therapies02:49

Cancer Therapies

9.1K
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...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

8.1K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

3.5K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

5.6K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Cancer Vaccines01:30

Cancer Vaccines

630
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Area of Science:

  • Oncology
  • Immunology
  • Pediatric Oncology

Background:

  • Osteosarcoma (OS) is the most common primary malignant bone tumor, frequently affecting children and adolescents.
  • Current chemotherapy regimens (methotrexate, cisplatin, doxorubicin, ifosfamide) have improved limb salvage rates but have not advanced OS treatment in decades.
  • Prognosis remains poor for patients with metastatic or recurrent osteosarcoma, highlighting the urgent need for novel therapeutic strategies.

Purpose of the Study:

  • To review the current landscape of immunotherapies for osteosarcoma.
  • To identify and discuss the existing limitations hindering the efficacy of immunotherapy in OS treatment.
  • To explore the potential of immunotherapy as a future treatment modality for osteosarcoma.

Main Methods:

  • Literature review of recent advancements in cancer immunotherapy.
  • Analysis of the application and efficacy of immunotherapeutic approaches in osteosarcoma models and clinical studies.
  • Discussion of challenges and future directions for immunotherapy in OS.

Main Results:

  • Immunotherapy has demonstrated significant success in various cancers, with expanding clinical applications.
  • The efficacy of immunotherapy specifically for osteosarcoma has not yet been definitively established.
  • Significant limitations and challenges impede the widespread use of immunotherapy in OS treatment.

Conclusions:

  • While immunotherapy holds potential for osteosarcoma treatment, its clinical effectiveness is currently unproven.
  • Further research is crucial to overcome current limitations and establish immunotherapy as a viable treatment option for OS.
  • Developing new treatment methods, including immunotherapy, is essential to improve outcomes for patients with osteosarcoma, especially those with advanced disease.
