Insights

Cancer impairs the immune system through various factors, including surgical stress and tumor-produced transforming growth factor beta (TGF-beta). Understanding these mechanisms is key for effective cancer immunotherapy in surgical patients.

Area of Science:

  • Oncology
  • Immunology
  • Surgical Oncology

Background:

  • Cancer can induce immunosuppression through host- or tumor-derived factors.
  • Tumor presence can lead to host debility and immune anergy.
  • Antitumor treatments may negatively impact host antitumor immunity.

Purpose of the Study:

  • To identify key mechanisms of cancer-induced immunosuppression.
  • To highlight the role of surgical stress and TGF-beta in immune impairment.
  • To emphasize the importance of understanding these mechanisms for immunotherapy development in surgical oncology.

Main Methods:

  • Investigated factors contributing to cancer-induced immunosuppression.
  • Focused on surgical stress effects.
  • Examined tumor-mediated production of growth factors, specifically transforming growth factor beta (TGF-beta).

Main Results:

  • Surgical stress is implicated as a significant cause of host immune impairment.
  • Tumor-mediated production of transforming growth factor beta (TGF-beta) contributes to immune impairment.
  • These factors collectively impair the host's antitumor immunity.

Conclusions:

  • Surgical stress and tumor-derived TGF-beta are critical contributors to cancer-induced immunosuppression.
  • Understanding these mechanisms is essential for developing successful immunotherapy strategies.
  • This knowledge is particularly crucial for patients undergoing surgery for cancer.

Cancer Therapies02:49

Cancer Therapies

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

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 specific...

Tumor Immunotherapy01:27

Tumor Immunotherapy

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 Vaccines01:30

Cancer Vaccines

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...
