Abstract

Insights

Global research on immunotherapy for epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) shows rapid growth. Key research gaps include optimal sequencing, biomarkers, and resistance mechanisms, guiding future therapeutic strategies.

Area of Science:

  • Oncology
  • Immunotherapy
  • Molecular Biology

Background:

  • Immunotherapy for EGFR-mutant NSCLC is a promising strategy.
  • Global research trends in this field are largely uncharacterized.
  • This study provides a bibliometric analysis of the field's evolution.

Purpose of the Study:

  • To conduct a comprehensive bibliometric analysis of EGFR-mutant NSCLC immunotherapy.
  • To characterize the evolution and current state of global research in this area.
  • To identify key research trends, collaborations, and influential entities.

Main Methods:

  • Bibliometric analysis of publications from 1995-2024.
  • Utilized Web of Science Core Collection, VOSviewer, CiteSpace, and R 'bibliometrix'.
  • Analyzed publication trends, citations, collaborations, and keywords.

Main Results:

  • 1,537 publications from 352 sources involving 12,131 authors were analyzed.
  • China led in publications; USA had the highest citation impact and collaboration.
  • Journal of Clinical Oncology was most influential; keyword analysis showed a shift towards immunotherapy and targeted therapies.

Conclusions:

  • EGFR-mutant NSCLC immunotherapy research is rapidly expanding.
  • Identified critical research gaps: optimal immunotherapy-EGFR-TKI sequencing, predictive biomarkers, and resistance mechanisms.
  • Findings guide future research to enhance therapeutic strategies in this evolving field.

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...

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...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

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...
