Targeted Cancer Therapies02:57

Targeted Cancer Therapies

9.0K
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...

Tumor Progression

7.7K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Area of Science:

  • Hepatology and Oncology
  • Gastroenterology
  • Cancer Research

Background:

  • Cholangiocarcinoma (CCA) is the second most common primary liver cancer, with rising incidence in Western countries.
  • Prognosis remains poor due to late diagnosis and limited curative options, primarily surgery.
  • Recent advances have improved understanding of CCA's molecular biology, diagnostics, and therapeutics.

Purpose of the Study:

  • To review current epidemiologic trends and novel etiologic risk factors for CCA.
  • To discuss the molecular pathogenesis, including the impact of etiology and location on the mutational landscape.
  • To provide an overview of diagnostic strategies, staging systems, and emerging therapeutic options for CCA.

Main Methods:

  • Comprehensive literature review of recent studies on cholangiocarcinoma.
  • Analysis of epidemiological data, molecular profiling, and clinical trial outcomes.
  • Critical evaluation of diagnostic techniques and therapeutic advancements.

Main Results:

  • CCA incidence is increasing globally, with evolving risk factors.
  • Distinct molecular profiles are associated with different etiologies and biliary locations.
  • Advances in diagnostics and targeted therapies are emerging, offering new hope.

Conclusions:

  • Understanding CCA's epidemiology and molecular basis is crucial for improved patient outcomes.
  • Multidisciplinary approaches integrating diagnostics and novel therapies are essential.
  • Future research should focus on personalized treatment strategies and early detection.
