Combination chemotherapy with gemcitabine and nab-paclitaxel for a metastatic pancreatic ductal adenocarcinoma patient undergoing hemodialysis

In cancer patients, impairment of kidney function is not uncommon. Recently, the efficacy of the combination of gemcitabine and nab-paclitaxel for pancreatic ductal adenocarcinoma (PDAC) patients has been reported, however, there is no recommendation for dose and administration to patients undergoing hemodialysis (HD). A 66-year-old man began receiving HD for chronic renal failure 4 years previously. He suffered from diarrhea, back pain, and loss of appetite, and his weight gradually decreased. Abdominal dynamic computed tomography showed a 45-mm hypodense mass in the pancreatic body and a 30-mm hypodense mass in the liver. The patient was diagnosed with metastatic PDAC. He started combination chemotherapy of gemcitabine and nab-paclitaxel without dose modification. He developed pneumonia and neutropenia in the first and second courses, so we modified to a 60% dose of gemcitabine and nab-paclitaxel on day 1 every 2 weeks. After dose modification, he continued combination chemotherapy for over 7 months without severe adverse events or tumor progression. Combination chemotherapy using gemcitabine and nab-paclitaxel was effective in a PDAC patient undergoing HD. While it is possible to originally administer these drugs with no dose modification, early dose modification was needed for our patient because of severe adverse events.
