Abstract:
A 50-year-old man who presented with a fever and epigastralgia was diagnosed to have esophageal carcinoma which was identified as poorly differentiated adenocarcinoma producing alpha-fetoprotein (AFP) with Barrett's esophagus. Computed tomography revealed multiple liver metastases and lymph node metastases surrounding the stomach. We first performed chemotherapy for the systemic lesions and proton beam therapy for the local control of lesions without complete remission and we were able to successfully control the frequently recurring lesions by proton beam therapy, cryotherapy and chemotherapy. A complete response has been maintained for 16 months and the overall survival time is 4 years and 2 months. Proton beam therapy for primary esophageal cancer and metastatic lesions was thus found to be an effective therapeutic option for such cases.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
