Pancreatic cancer arises from the pancreatic ductal epithelium or acinar epithelium, with geographic variation in incidence. It is highly invasive and prone to early metastasis. Clinical manifestations include abdominal pain, jaundice, weight loss, and gastrointestinal symptoms.
1. Pancreatic ductal adenocarcinoma
The most common subtype, accounting for >95% of cases, arising from ductal epithelium. It is highly malignant, progresses rapidly, and carries a very poor prognosis.
2. Other pancreatic cancer types
Including acinar cell carcinoma and pancreatoblastoma. These are relatively rare, have distinct biological behavior, and require different treatment strategies.
3. Cystic neoplasms
Including IPMN and mucinous cystic neoplasms, which have malignant potential and are considered precancerous lesions requiring active surveillance.
4. Neuroendocrine tumors
Arise from neuroendocrine cells and account for 1%–2%. They generally grow more slowly and have a better prognosis than ductal adenocarcinoma.
1. Hereditary susceptibility and genetic alterations
Approximately 10% of patients have hereditary susceptibility. KRAS mutations are common; other implicated genes include BRCA1/2.
Long-term smoking approximately doubles risk. High-fat diet, obesity, and excessive alcohol intake may also increase risk.
Chronic pancreatitis and diabetes are risk factors. New-onset diabetes or worsening glycemic control may be an early signal.
Age is an important risk factor, with most cases occurring in individuals older than 65 years. Incidence is slightly higher in men than in women.
1. Avoid risk factors
Smoking cessation is the most effective preventive measure. Maintain a healthy body weight and limit alcohol intake.
2. Healthy dietary habits
Increase fruit and vegetable intake, reduce red and processed meat, and control total caloric intake to prevent obesity.
3. Regular examinations and screening
High-risk individuals should undergo periodic abdominal imaging surveillance. Prompt evaluation is recommended when suspicious symptoms occur.
4. Chronic disease management
Actively manage chronic pancreatitis and diabetes. New-onset or worsening diabetes warrants attention to potential pancreatic pathology.
5. Genetic counseling and testing
Individuals with a family history may consider genetic counseling to assess individual risk and develop personalized strategies.
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that pancreatic cancer is insidious and aggressive, posing a serious threat to health. Early diagnosis and standardized treatment are pivotal to improving cure rates. MDT-based multimodal management, incorporating minimally invasive surgery and emerging therapies such as targeted and immunotherapy, continues to improve outcomes. The public should remain vigilant for symptoms, undergo regular health examinations, maintain healthy lifestyle practices, avoid risk factors, and respond scientifically to this challenge.
