What Is Pancreatic Cancer (Pancreatic Adenocarcinoma)?
Pancreatic Cancer (Pancreatic Adenocarcinoma) is a formidable disease characterized by the malignant transformation of cells in the pancreas, commonly arising from the ducts that transport digestive enzymes. The pancreas plays an essential role in digestion and blood sugar regulation, and its dysfunction can have significant systemic consequences. This cancer type is notoriously aggressive and often diagnosed at an advanced stage, making treatment more challenging.
At a cellular level, understanding Pancreatic Cancer (Pancreatic Adenocarcinoma) involves recognizing the Warburg effect, where cancer cells consume glucose at rates significantly higher than normal cells — nearly 200 times greater. This metabolic reprogramming supports the rapid growth and proliferation of cancer cells, posing unique therapeutic challenges and opportunities. Rising research focuses on targeting these metabolic vulnerabilities for more effective treatments.
Pancreatic Cancer (Pancreatic Adenocarcinoma) affects over 495,000 individuals worldwide annually, with recent data from the World Health Organization indicating an upward trend. In Hong Kong and across Asia, its prevalence aligns closely with global trends, albeit with specific regional differences. Notably, factors such as genetic predispositions, lifestyle, and dietary habits prevalent in Asian populations affect incidence rates.
A diagnosis of Pancreatic Cancer (Pancreatic Adenocarcinoma) impacts patients both physically and emotionally. Symptoms often include persistent fatigue, abdominal pain, jaundice, and significant and unexplained weight loss. Psychologically, the burden can be immense, encompassing anxiety, depression, and stress due to uncertain prognoses and intensive treatment regimens.
- Common symptoms: Jaundice, abdominal pain, and unexplained weight loss.
- Affected demographics: Predominantly individuals over 60 years, with a slight male predominance.

Empirical research and ongoing collaborations with international cancer treatment centers, such as those at MD Anderson and Shenzhen Qianhai Taikang, aim to refine diagnostic and therapeutic approaches, offering hope through innovative science and compassionate care.
Causes and Risk Factors of Pancreatic Cancer (Pancreatic Adenocarcinoma)
Identifying the causes and risk factors of Pancreatic Cancer (Pancreatic Adenocarcinoma) is crucial for both prevention and early treatment. Genetic predispositions play a significant role, with mutations in BRCA1 and BRCA2 genes known to increase risk. These genetic factors emphasize the importance of family histories and potential hereditary screenings.
Environmental exposures significantly contribute to risk, especially smoking, which doubles the risk of developing Pancreatic Cancer (Pancreatic Adenocarcinoma). Furthermore, occupational exposures to certain industrial chemicals may elevate risk. Lifestyle choices, particularly obesity and high alcohol consumption, also pose significant threats, often tied to chronic pancreatitis and diabetes, which are common precursors.
A noteworthy metabolic vulnerability of Pancreatic Cancer (Pancreatic Adenocarcinoma) is its reliance on glutamine. Approximately 50% of cancer cells in this category depend on glutamine for nucleotide synthesis, highlighting another avenue for potential therapeutic intervention. Targeting these metabolic dependencies is a promising strategy currently explored by leading researchers, including collaborations involving Nobel laureates such as Dr. Li Guohua and Prof. Liu Guolong.
In Hong Kong and wider Asia, unique regional factors include dietary habits and the prevalent hepatitis B infection rate, which has a nuanced but significant impact on pancreatic cancer incidence. The linkage between liver diseases and pancreatic health highlights the interconnectedness of metabolic health risks prevalent in these populations.
- Genetic risks: BRCA1/2 mutations.
- Lifestyle contributions: Smoking, obesity, and alcohol consumption.
- Metabolic dependencies: Warburg effect and glutamine reliance.
Proactive measures, including lifestyle modifications and early screening, are vital in managing these risks. Encouraging regular health checks and lifestyle evaluation could lead to earlier diagnosis and more favorable outcomes. Educational initiatives supported by health institutions, such as the WHO and the National Cancer Institute, are essential in raising awareness of these risk factors across Asia and beyond.

- Abdominal pain: Persistent, often dull pain in the upper abdominal region or back that worsens after meals or when lying down.
- Unintended weight loss: Rapid and unexplained weight loss resulting from impaired digestion and absorption of nutrients.
- Nausea and vomiting: Often arising due to obstruction or pressure on the stomach and duodenum.
- Loss of appetite: Tumor-related biochemical changes interfering with hunger cues and appetite regulation.
- Pale, greasy stools: Indicative of blocked pancreatic enzymes required for fat digestion, leading to steatorrhea.
- Fatigue: Profound physical and mental tiredness often due to changes in metabolism and systemic inflammatory response.
- Blood clots: Deep vein thrombosis (DVT) or pulmonary embolism (PE) may occur from the hypercoagulable state induced by pancreatic cancer.
- New-onset diabetes: Sudden and unexplained onset diabetes mellitus can be an early warning sign due to the compromised endocrine function of the pancreas.
Symptoms Based on Tumor Stage
Clinically, pancreatic cancer symptoms can vary depending on tumor stage:
- Stage 1: Minimal symptoms, often asymptomatic or mild and easily overlooked symptoms like mild digestive discomfort.
- Stage 2: Increased abdominal pain, onset of weight loss, occasional mild jaundice if tumor growth starts obstructing the bile duct.
- Stage 3: More pronounced symptoms including consistent jaundice, moderate to severe abdominal discomfort, obvious weight loss, marked fatigue, and often new-onset diabetes mellitus.
- Stage 4: Severe symptoms like persistent and debilitating pain, significant weight loss, extensive jaundice, severe fatigue, and development of liver or lung symptoms from metastatic spread.
