Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.5K
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

6.2K
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...

Summary

Liver cancer incidence is shifting globally due to changing risk factors like viral hepatitis and metabolic conditions. Prevention efforts must address these shifts and disparities in disadvantaged populations.

Area of Science:

  • Hepatology and Oncology
  • Public Health and Epidemiology

Background:

  • Liver cancer is a major global health concern, ranking sixth in incidence and third in mortality worldwide.
  • Significant geographical variations exist in liver cancer rates, with recent trends showing declining incidence in some high-risk areas and increases in others.
  • Shifting risk factor landscapes, including viral hepatitis and emerging metabolic conditions, are driving these epidemiological changes.

Purpose of the Study:

  • To analyze the epidemiological trends of liver cancer incidence and mortality.
  • To identify the impact of established and novel risk factors on these trends.
  • To highlight the importance of prevention and equitable research for disadvantaged populations.

Main Methods:

  • Analysis of global liver cancer incidence and mortality data.
  • Evaluation of the contributions of various risk factors, including viral hepatitis and metabolic syndrome.
  • Examination of socioeconomic factors influencing liver cancer prevalence.

Main Results:

  • Global liver cancer incidence and mortality rates exhibit significant geographical disparities.
  • Trends indicate a decline in some high-incidence regions and an increase in others, linked to evolving risk factors.
  • Hepatitis B and C virus (HBV/HCV) control has shown success, but metabolic conditions are increasingly significant drivers of liver cancer.
  • Liver cancer disproportionately affects socioeconomically deprived populations.

Conclusions:

  • Liver cancer epidemiology is dynamic, influenced by both viral and metabolic risk factors.
  • Continued efforts are needed to combat viral hepatitis and address the growing burden of metabolic diseases.
  • Equitable access to research, early diagnosis, and treatment is crucial, particularly for vulnerable and disadvantaged communities.
