简要总结
This research aims to study the effect of postoperative adjuvant therapy with a MiniPDX drug sensitivity test for biliary tract cancer.
详细描述
Biliary tract cancer (BTC) is the most common primary malignancy of the biliary tract. Currently, surgery provides the only ray of hope for the management of BTC, however, the disease is progressing rapidly, lacking of obvious symptoms in its early stages, with metastases to lymph nodes. Only 20-30% of patients are eligible for surgical resection with curative intent. In addition, the treatment remains difficult because of the lack of effective chemotherapeutic agents and the combined regimens for reference.
In this study, fresh tumor samples generated directly from patients will be used for a MiniPDX test and inoculated in mice subcutaneously. The candidate drugs or regimens can be tested in mice to determine the best treatment for that specific patient after surgery.
The study aims to evaluate the efficacy and accuracy of MiniPDX assays for antitumor chemotherapeutics.
