Insights

Tumor progression and treatment response depend on the host immune system and therapeutic antibodies. Understanding these immunological parameters is key for improving cancer therapies and clinical outcomes.

Area of Science:

  • Oncology
  • Immunology
  • Pharmacology

Background:

  • Malignant tumor progression is influenced by host immunological parameters.
  • Lymphocytic infiltration in tumors correlates with improved clinical outcomes.
  • Therapeutic antibodies modulate immune responses, impacting cancer treatment efficacy.

Purpose of the Study:

  • To review clinical data on the interaction between cancer therapies and the immune system.
  • To explore the role of immunological parameters in chemotherapy and targeted therapy response.
  • To provide an overview of immune system modulation by targeted therapies.

Main Methods:

  • Review of existing clinical data.
  • Analysis of studies on chemotherapy and targeted therapy response.
  • Examination of immunological pathways affected by therapeutic antibodies.

Main Results:

  • Lymphocytic infiltrate is a positive prognostic factor in various cancers.
  • Pre-therapeutic lymphocytic infiltrate enhances response to neoadjuvant chemotherapy.
  • Targeted therapies like trastuzumab, rituximab, and alemtuzumab interact with immune pathways, crucial for outcomes.

Conclusions:

  • Immune system modulation is critical for the efficacy of both classical chemotherapy and targeted therapies.
  • Understanding host immune parameters can optimize cancer treatment strategies.
  • Targeted therapies can modulate the immune system, influencing treatment effectiveness and toxicity.

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.
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...

Cytotoxic T Cells-mediated Immune Response01:27

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...
