Purpose:
Adenosquamous pancreatic cancer represents 0.9-4.4% of exocrine pancreatic neoplasms and is generally thought to be associated with a worse prognosis than the more common ductal adenocarcinoma. The aim of the current study is to describe the outcome of patients with adenosquamous pancreatic cancer in our institution who were managed in a multidisciplinary environment.
Methods:
In a retrospective analysis between February 1990 and February 2010, we identified from our database of 890 pancreatic lesions resected for malignancy six cases (0.67%) of adenosquamous cancer. We assessed the demographics, clinical and radiological features, surgical approach, histological details and follow-up data.
Results:
All patients underwent pylorus-preserving pancreatoduodenectomy. Two patients, one male and one female, died in the preoperative period due to sepsis and myocardial infarction, respectively. The remaining four patients received adjuvant chemotherapy. One male patient died with local recurrence after 13 months; however, one female and two male patients are still alive with Karnofsky status of 80-90% at 15, 14 and 39 months after the operation, respectively.
Conclusions:
The prognosis of adenosquamous pancreatic cancer remains very poor, apparently worse than ductal pancreatic cancer. Nevertheless, our report and the review of literature seem to show that "curative" surgical resection associated with adjuvant treatment may offer the best results with a similar survival rate than ductal pancreatic cancer.
