Pancreatic cancer is one of the deadliest cancers commonly diagnosed at an advanced stage. Early diagnosis is crucial for the timely and potentially curative treatment of this highly fatal disease. Although screening tests have improved the survival rate in malignancies such as colon, breast, cervical and prostate cancer, there is currently no effective screening method available for the early detection of pancreatic cancer. As the sensitivity and specificity of existing biomarkers, such as carbohydrate antigen 19-9, for the early detection of pancreatic cancer is low, there is a pressing need for the identification of novel cancer markers. An increase in erythropoietin (EPO) levels has been observed in several cases of pancreatic neoplasms. However, the potential role of EPO as a biomarker of pancreatic cancer or malignant transformation requires further investigation. We herein present a case of increased EPO levels in an adult male patient with stage IV pancreatic cancer.

Tumor genome sequencing is important for increasing our understanding of the development of cancer, which may be affected by different therapies. In the present study, genomic evolution was investigated in a patient with stage IV pancreatic cancer bearing a germline breast cancer 2 (BRCA2) mutation. The patient received cisplatin, a DNA cross-linking agent, which led to a long-lasting complete response. Eventually the patient developed brain metastasis, suggesting the acquisition of resistance to cisplatin. He subsequently underwent brain lesion resection, radiofrequency ablation and chemotherapy, again resulting in long-lasting response. Samples of blood, pancreatic tumor tissue and brain metastases were collected and the extracted DNA was sequenced. The pancreatic and brain lesions, when compared with the blood samples, exhibited mutations in the BRCA1 and checkpoint kinase 2 genes, in addition to the germline BRCA2 mutation. The brain lesion, when compared with the primary tumor, harbored no additional mutations or copy-number variations. These findings suggest that the isolated relapse in the brain was due to pharmacological sanctuary rather than genomic alterations. It may be suggested that the presence of defects in the homologous recombination repair pathways are associated with a good prognosis and clinical sensitivity to agents that damage the DNA in pancreatic cancer.
