Pancreatic cancer, specifically pancreatic ductal adenocarcinoma (PDAC), is one of the deadliest cancers with a five-year survival rate of <10%. Because of its high grade and lack of known effective standard therapies, recent clinical trials have utilized novel approaches, including immunotherapy-based treatments, targeted agents and combinations.
Immunotherapy: Although modestly successful at best, the first immune checkpoint inhibitors and CAR-T cell therapies are currently under clinical testing in combination with other anti-neoplastic modalities due to the inherently immunounsupprotive microenvironment of PDAC. For example pembrolizumab (Keytruda) is being tested for use in patients with tumor-high microsatellite instability (MSI), whole trials are looking at how to combine immunotherapy with chemotherapy or stromal-targeting drugs to increase immune cell infiltration.
Targeted Therapy: This category includes therapies which are designed to target specific mutations in PDAC, including the all too famous KRAS G12D mutation found in more than 90% of cases. One approach that is being tested in trials for drugs like MRTX1133 is to interfere with this mutation's part in driving cancer growth. Further, PARP inhibitors like olaparib (Lynparza) have given a glimmer of hope for BRCA mutation positive patients.
Combination Therapies: Viable strategies combine chemotherapies like FOLFIRINOX with new agents like immune checkpoint inhibitors or stroma-modifying drugs. These combination strategies are designed to improve drug effectiveness and bypass the dense, fibrotic tumor microenvironment that is partly responsible for the high failure rate of therapies in pancreatic cancer.

Pancreatic cancer is the most lethal of all forms of cancer, mainly due to the high aggressiveness of pancreatic ductal adenocarcinoma (PDAC), which accounts for more than 90% of all cases. Pancreatic cancer kills over 500,000 people globally each year and is only expected to get more common due to lifestyle changes and an ageing world population.
The disease presents in a late-stage diagnosis, with as many as 80% of patients already having advanced or metastatic disease at the time of their original identification.
Geographic distribution and demographic characteristics
The incidence of pancreatic cancer also varies by region. The highest incidences of OCNA in the population were reported for Asia, and specifically Japan (age-standardised rate 0·407) and China (0·382), and they presented slightly higher age-standardised ratesbut low numbers in Europe and North America. Lifestyle changes, more screening for a recommendation and populations aging contribute to these total.
In the US, it is projected that by 2024 about 64,000 new cases will be identified each year.
Pancreatic cancer also arises in other parts of South America and Australia at region-specific minimum levels nearing several advances annually.
Many risk factors are related to an increased risk of pancreatic cancer. Most cases are among people 65 or older, and age is a chief risk factor. Diagnosis most commonly occurs in those aged over 70, with the median age at diagnosis being 70 years.
Men are slightly more at risk than women, and certain racial and ethnic groups such as African Americans show higher incidence rates.
Diabetes and chronic pancreatitis.
Smoking: Both past and current smokers have a dramatically increased risk.
Obesity There is a higher risk of pancreatic cancer in men with BMI over 30.
Genetic predisposition including inherited mutations, such as BRCA1/2, PALB2 and Lynch Syndromes (up to 10% of cases)
Pancreatic cancer (PC) is a highly lethal form of malignancy, and its 5-year survival rate worldwide fluctuates between 2% and 10% [3]
This poor survival is explained by the fact that disease often presents late (stage IV),we only have limited effective forms of screening and because tumor rapidly metastasize early in their natural history. Patients with early stage diagnosis and resectable cancers enjoy a better prognosis, but recurrence is common despite surgery.
Given the global ageing population, overall pancreatic cancer incidence is projected to rise. Rate of pancreatic cancer death increase for men, doctor discovery could be step toward ending itExperts say by 2030 pancreatic cancer will be second most common cause of cancer deaths worldwide.
This trend underscores an increasing demand for innovations in diagnosis, treatment options, and personalized approaches to therapy that will drive improved outcomes to patients.
In the future, personalized medicine strategies will be further refined, especially for KRAS and BRCA mutations to determine treatment of greatest benefit. The incorporation of immunotherapies as well as combination treatment programs are anticipated to enhance person results, and the identification of biomarkers will certainly influence individualized therapy biuss. Accessibility is still a robust obstacle, treatment costs are high, and regulatory constraints inhibit immediate assistance especially in more disadvantaged sectors.
