Description
Pancreatic Ductal Carcinoma (PDAC): A Highly Aggressive Form of Pancreatic Cancer
Pancreatic ductal carcinoma, also known as pancreatic ductal adenocarcinoma (PDAC), is a type of cancer that begins in the cells of the pancreas's ducts. It is the most common form of pancreatic cancer, accounting for more than 80% of cases [3]. The disease starts in the cells lining small tubes in the pancreas called ducts [7], and it is characterized by the presence of extensive desmoplastic stroma, which can constitute up to 90% of the tumor volume [4].
Causes and Risk Factors
Pancreatic cancer, including PDAC, is a highly aggressive form of cancer that is often diagnosed in advanced stages. The exact causes of pancreatic cancer are not well understood, but several risk factors have been identified, including smoking, obesity, and long-standing type 2 diabetes [13]. These conditions can increase the risk of developing pancreatic cancer.
Symptoms and Diagnosis
Pancreatic ductal carcinoma typically does not cause symptoms in its early stages. However, as the disease progresses, patients may experience weight loss, abdominal pain, jaundice, and other symptoms. The diagnosis of PDAC is often made through imaging tests such as CT scans or MRI, which can help identify tumors in the pancreas [11].
Treatment Options
Unfortunately, pancreatic cancer, including PDAC, has a poor prognosis, with an overall 5-year survival rate of only 6% [11]. Surgical resection is the only current option for a cure, but it is only possible in about 20% of cases. Other treatment options include chemotherapy and radiation therapy, which can help manage symptoms and improve quality of life.

Signs and Symptoms
Common Signs and Symptoms of Pancreatic Ductal Carcinoma
Pancreatic ductal carcinoma, a type of pancreatic cancer, can cause a range of symptoms, which may vary in severity and duration. The following are some common signs and symptoms associated with this condition:
- Jaundice: A yellowing of the eyes and skin due to bile buildup in the body [5][7]
- Dark urine or light-colored stools: Changes in urine and stool color can indicate a blockage in the bile ducts [6][7]
- Abdomen or back pain: Pain in the upper abdomen or back can be a symptom of pancreatic cancer, especially if it radiates to other areas [9][13]
- Weight loss: Unintentional weight loss is a common symptom of pancreatic cancer, often accompanied by decreased appetite and fatigue [14][15]
- Nausea and vomiting: Some people may experience nausea and vomiting due to the tumor's location and pressure on surrounding organs [6][14]
Other Possible Symptoms
In addition to these common symptoms, some individuals with pancreatic ductal carcinoma may also experience:
- Bloating: Feeling bloated or uncomfortable in the abdominal area
- Fatigue: Feeling extremely tired or weak
- Itchy skin: Itching sensations on the skin, often accompanied by jaundice
Important Note
It's essential to note that these symptoms can be caused by other conditions as well. If you're experiencing any of these

Diagnostic Tests
Imaging Tests for Pancreatic Ductal Carcinoma (PDAC)
Pancreatic ductal carcinoma, also known as pancreatic cancer, is a type of cancer that affects the pancreas. Diagnosing PDAC can be challenging, but various imaging tests can help identify the disease.
- Computed Tomography (CT) Scan: A CT scan uses X-rays and computer technology to create detailed images of the pancreas and surrounding tissues. It can help detect tumors, determine their size, and assess whether they have spread to other areas [7][9].
- Positron Emission Tomography (PET) Scan: A PET scan is a type of imaging test that uses small amounts of radioactive material to create images of the pancreas and surrounding tissues. It can help identify cancer cells and determine their extent [11].
- Magnetic Resonance Imaging (MRI): An MRI uses magnetic fields and radio waves to create detailed images of the pancreas and surrounding tissues. It can help detect tumors, assess their size, and evaluate whether they have spread to other areas [9][11].
- Endoscopic Ultrasound (EUS) and Fine Needle Biopsy: EUS is a test that uses an endoscope with an ultrasound probe to create images of the pancreas and surrounding tissues. It can help detect tumors and obtain tissue samples for biopsy, which can confirm the diagnosis of PDAC [5][10].
Other Diagnostic Tests
In addition to imaging tests, other diagnostic tests may be used to diagnose PDAC, including:
- Blood Tests: Blood tests can help identify tumor markers linked to pancreatic cancer. They can also guide decisions on the management of PDAC [3].
- Liver Function Tests: Liver function tests can help assess liver health and detect any abnormalities that may indicate pancreatic cancer [1].

Treatment
Current First-Line Treatments for Pancreatic Ductal Adenocarcinoma (PDAC)
According to recent studies, the current first-line treatments for PDAC are FOLFIRINOX or gemcitabine plus nab-paclitaxel [6][9]. These treatment options have shown significant improvement in overall survival and progression-free survival rates compared to other chemotherapy regimens.
FOLFIRINOX
FOLFIRINOX is a combination of 5-fluorouracil (5-FU), leucovorin, oxaliplatin, and irinotecan. This regimen has been shown to be highly effective in treating PDAC, with a median overall survival rate of approximately 11 months [9]. FOLFIRINOX is typically administered as an infusion over several hours.
Gemcitabine plus Nab-Paclitaxel
The combination of gemcitabine and nab-paclitaxel has also been shown to be highly effective in treating PDAC, with a median overall survival rate of approximately 8.5 months [6]. This regimen is typically administered as an infusion over several hours.
Other Treatment Options
Apart from FOLFIRINOX and gemcitabine plus nab-paclitaxel, other treatment options for PDAC include:
- Gemcitabine alone: This has been a standard treatment option for PDAC in the past, but its efficacy is lower compared to the above-mentioned regimens [7].
- Nalirifox: This is a combination of liposomal irinotecan, 5-FU/leucovorin, and oxaliplatin. It has been approved for use in patients with metastatic PDAC who have not had any other treatment [9].
Treatment Goals
The primary goal of pancreatic cancer treatment is to get rid of the cancer when possible. When that's not possible, the focus may be on improving quality of life and keeping the cancer from growing or causing more harm [12]. Treatment options for PDAC may include surgery, radiation, chemotherapy, chemoradiation, and supportive care.

Differential Diagnosis
Differential Diagnosis of Pancreatic Ductal Carcinoma
Pancreatic ductal carcinoma (PDC) is a type of cancer that arises from the pancreatic ductal epithelium. The differential diagnosis of PDC involves distinguishing it from other conditions that may present with similar symptoms or imaging features.
Key Differential Diagnoses:
- Acute Pancreatitis: This condition can mimic PDC in terms of abdominal pain and elevated pancreatic enzymes, but it is typically characterized by a more rapid onset and resolution.
- Chronic Pancreatitis: This condition involves chronic inflammation of the pancreas and can lead to fibrosis and calcification. It may present with similar symptoms to PDC, but imaging studies often show evidence of chronic pancreatitis.
- Lymphoma: Lymphoma can involve the pancreas and may present with similar symptoms to PDC. Imaging studies may show lymphadenopathy or a mass in the pancreas.
- Fatty Infiltration of the Pancreatic Head: This condition involves the accumulation of fat in the pancreatic head and can mimic PDC on imaging studies.
Other Differential Diagnoses:
- Distal Cholangiocarcinoma (dCCA): dCCA is a type of cancer that arises from the bile ducts and may present with similar symptoms to PDC.
- Undifferentiated Carcinoma: This is a rare type of cancer that can involve the pancreas and may present with similar symptoms to PDC.
Key Imaging Features:
- Pancreatic Ductal Dilatation: This feature is often seen in PDC, but it can also be seen in other conditions such as chronic pancreatitis or dCCA.
- Tumor Thrombus: A tumor thrombus may be seen in PDC, particularly if the cancer has spread to the bile ducts.
Clinical Implications:
- Preoperative Histological Diagnosis: The differential diagnosis of PDC can be challenging preoperatively, and a definitive diagnosis often requires histological examination of tissue.
- Different Treatments: The treatment of PDC may differ from that of other conditions such as chronic pancreatitis or dCCA.

Approximately 75% of all pancreatic carcinomas occur within the head or neck of the pancreas, 15-20% occur in the body of the pancreas, and 5-10% occur in the tail.
- [2] The differential diagnosis between primary adenocarcinoma of the pancreas head and distal cholangiocarcinoma remains a clinical challenge. Recent studies have shown important differences in terms of survival between these tumors. Therefore, different treatments should be considered, but the preoperative histological diagnosis is still difficult.
