Abstract
Background
The neoadjuvant chemotherapy using CDDP and 5-FU(CF) is the standard treatment for advanced esophageal cancer, defined as clinical stage II/III in Japan. However, more powerful chemotherapy has been required for the treatment of cases of cStageIII cases. In 2011, the combination treatment of CF and Docetaxel (DCF) was introduced for the treatment of those cases in our institute. DCF therapy increased chemotherapy remarkable cases. But, adverse events occur at high rates, including high myelosuppression. Therefore, it is necessary to ensure support by early intervention of supportive therapy so as not to exacerbate adverse events. We report about treatment outcome in preoperative DCF therapy cases.
Methods
We treated 128 esophageal cancer patients who underwent surgery following preoperative DCF therapy between 2011 and July 2017, and preoperative DCF was administered to 128 patients 2 course completely. The neoadjuvant chemotherapy regimen using DCF is Docetaxel:70mg/m2 (day1) + CDDP:70mg/m2 (day1) + 5-FU:700mg/m2 (day1–5).
Results
In the preoperative DCF group, overall response rate (over PR) was 51.5%. There were 37 cases in 128 cases of pathological tissue effect judgment for Grade 2 and 3. 14 cases of them (14cases/37cases:37.8%) had lymph node metastasis. Therefore it is necessary to control lymph node metastasis by surgery even in a remarkable group. Almost all patients experienced grade 4 adverse events, particularly neutropenia is a high frequency. From the start of chemotherapy, pretreatment of intraoral infection lesion and prevention and treatment of oral mucositis are performed. Considering the degree of myelosuppression during initial chemotherapy, in the second course, we actively administer G-CSF preparation.
Conclusion
A good prognosis can be expected if preoperative DCF therapy is effective. It is necessary to perform intensive and safe preoperative chemotherapy with appropriate supportive therapy intervention.
