About

The purpose of this study is to evaluate the efficacy of vitamin C plus herbal medicine in improving the quality of life for metastatic pancreatic cancer patients who are resistant to chemotherapy.

Full description

Pancreatic cancer is a highly lethal malignancy with a 5-year survival less than 10%. Approximately 80% of patients with pancreatic cancer are diagnosed at an advanced stage. Chemotherapy is one of the major treatments for advanced pancreatic cancer. In 2011, the PRODIGE trial has shown that oxaliplatin, irinotecan, fluorouracil, and leucovorin (FOLFIRINOX) was associated with a survival advantage but had increased toxicity. In 2013, the MPACT trial has confirmed the efficacy of gemcitabine combined with nab-paclitaxel as the first-line treatment to metastatic pancreatic cancer. However, the side-effects related to chemotherapy including anemia, hand/foot numbness, fatigue, nausea, and malnutrition have impaired the quality of life for patients.

Vitamin C, also called ascorbate, is an essential nutrient for the human body. It modulates metabolism, immune reaction, collagen synthesis, and iron absorption. Some studies have shown that high-dose intravenous Vitamin C may be effective against various types of cancer. Meanwhile, medium or low dose of Vitamin C may increase iron absorption, improve anemia, alleviate pain and hand/foot numbness, and thus improve the quality of life for patients with terminal stage pancreatic cancer. In addition, numerous evidence has proved the efficacy of Reishi and Cordyceps in alleviating the side effects related to chemotherapy.

The purpose of this study is to evaluate the efficacy of vitamin C plus herbal medicine on improving the quality of life for metastatic pancreatic cancer patients who are resistant to two lines of systemic chemotherapy, including gemcitabine based, fluorouracil based, or other regimen. Fifty patients who have tumor progression after receiving two lines of chemotherapy will be recruited. These patients will receive Vitamin C plus herbal medicine. Quality of life, rate of hand/foot numbness, severity of pain, rate of anemia, and overall survival are measured.
