A 71-year-old woman presented with an abdominal mass and ascites and was
subsequently admitted to our hospital in June 1995. Further examination
revealed that the mass was malignant and, as a result, surgery was
indicated. However, the mass demonstrated widespread peritoneal
dissemination, which therefore could not be resected, and pathological
findings suggested a malignant peritoneal mesothelioma. The patient showed
a remarkable response to combined chemotherapy with an accompanying
intraperitoneal injection of cisplatin and etoposide and an intravenous
injection of caffeine. However, owing to side effects, this regimen was
discontinued. The patient was administered a combination drug of uracil and
tegafur (UFT) in addition to intraperitoneal injection of cisplatin as an
outpatient. By the 223rd day after surgery, the tumor mass and ascites had
completely disappeared according to the CT. Hence chemotherapy was judged
to have resulted in complete remission. Such a marked response to
chemotherapy is rare in an advanced malignant peritoneal mesothelioma such
as the present case. Eight months later, the tumor recurred in the pleura.
Another regimen of chemotherapy with cisplatin and CPT-11 was performed.
However, this treatment proved ineffective. The patient subsequently died
of respiratory failure in January 1997 due to the mesothelioma. This is a
case report of complete remission of malignant peritoneal mesothelioma by
combined chemotherapy.
