Tumor Immunotherapy01:27

Tumor Immunotherapy

860
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

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...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

7.4K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

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

624
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
  • Dermatology

Background:

  • Merkel cell carcinoma (MCC) is an aggressive skin cancer.
  • MCC exhibits chemosensitivity but high rates of relapse and chemoresistance.
  • The introduction of checkpoint inhibitors has significantly altered advanced MCC management.

Purpose of the Study:

  • To review the impact of immunotherapy in unresectable and metastatic MCC.
  • To discuss ongoing research in adjuvant and neoadjuvant settings for MCC.
  • To explore future immune-based strategies for MCC treatment.

Main Methods:

  • Literature review of immunotherapy in Merkel cell carcinoma.
  • Analysis of clinical trial data for checkpoint inhibitors in advanced MCC.
  • Synthesis of current research and future directions in MCC immunotherapy.

Main Results:

  • Checkpoint inhibitors have shown significant efficacy in advanced MCC.
  • Immunotherapy represents a paradigm shift in managing unresectable and metastatic MCC.
  • Research is expanding to neoadjuvant and adjuvant immunotherapy for earlier stages.

Conclusions:

  • Immunotherapy, especially checkpoint inhibitors, is a cornerstone in advanced MCC treatment.
  • Further research is crucial for optimizing immune-based strategies across all stages of MCC.
  • Future directions involve refining and expanding immunotherapy applications for this challenging cancer.
