QUESTION from Los Angeles, USA

As for the National Cancer Center Hospital in Tokyo, they always try surgery if it is possible.

Only stage 4 patients have case-by-case treatment. But even in stage 4 cases, Japaneses perform a laparoscopic peritoneal lavage to check peritoneal dissemination. If it is negative, the patient could be prepare for surgery. Anyway, they will receive chemotherapy.
I don’t know about treatment in Peru, but probably follows the American guidelines.

I hope this could answer your question.
