Summary
Online information about pancreatic cancer is often misleading. This study found significant misinformation and commercialized content in user questions and news articles, potentially leading to poor health decisions.
Area of Science:
- Oncology
- Health Communication
- Digital Health
Background:
- Inaccurate online health information can lead to detrimental patient decisions.
- Pancreatic cancer information requires careful dissemination due to its severity and rarity.
Purpose of the Study:
- To analyze online information exchange trends and content accuracy regarding pancreatic cancer.
- To identify prevalent topics and potential misinformation in user-generated content and news.
Main Methods:
- Collected 35,596 questions and 83,888 answers from Naver (Jan 2003-May 2020).
- Analyzed 8,495 related news articles from the same period.
- Employed structural topic modeling, keyword frequency analysis, and qualitative coding by medical professionals.
Main Results:
- Both user questions and news articles on pancreatic cancer increased over time.
- Topics on symptoms, diagnostic tests, and new technologies became more prominent.
- Misinformation, including focus on non-early symptoms like back pain and overemphasis on blood biomarker tests, was prevalent.
Conclusions:
- Online platforms like Naver contain significant misinformation and commercialized content about pancreatic cancer.
- The quality of information regarding symptoms and diagnostic tests is concerning.
- There is a critical need for accurate, evidence-based pancreatic cancer information online.

01:21Cancer Survival Analysis
442
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

3.9K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
