[A case of interstitial pneumonia induced by CPT-11 for local recurrence of rectal cancer].

A 60-year-old man underwent total pelvic exenteration for rectal cancer and urinary bladder invasion.He received adjuvant chemotherapy with S-1 and PSK.Because of local recurrence in the 4th postoperative month, he underwent FOLFIRI therapy followed by mFOLFOX6 therapy.

[A long-term survival case of local recurrence of breast cancer treated with combined modality therapy].

The case was a 70-year-old woman. In 1997, the patient underwent pectoral muscle-preserving mastectomy and axillary/subclavicular lymph node dissection for the treatment of right breast cancer. Histological diagnosis was invasive ductal carcinoma (T2, N2, M0, Stage IIIA).

[A case of unresectable multiple hepatic metastases from colorectal cancer successfully treated with IRIS (S-1, CPT-11) therapy].

In a patient with multiple liver metastases of colorectal cancer whose tumor response had been achieved by 5-FU hepatic arterial infusion, a catheter for arterial infusion chemotherapy was occluded resulting in re-elevation of tumor marker levels. For this reason, a second-line IRIS therapy using S-1 and CPT-11 was started. IRIS therapy reduced tumor marker levels to a degree greater than that of previously achieved with 5-FU hepatic arterial infusion, and a diagnostic imaging allowed a judgment of partial response.

[A case of unresectable and multiple advanced primary cancers of the stomach and rectosigmoid colon with hepatic metastases successfully treated with FOLFIRI for local control of a gastric lesion].

The patient was a 59-year-old man who was hospitalized at our department for intestinal obstruction. Contrast enhanced abdominal CT showed a rectosigmoid tumor invading the left pelvic wall and multiple metastatic hepatic tumors. Colonoscopy showed a type-2 cancer in the rectosigmoid region.

[A case of stage IV breast cancer responding to S-1 therapy after FEC and PTX therapies].

In November 2005, a 34-year-old female presented to our department with a bleeding tumor on her right breast. She noticed the tumor approximately two years ago but she left it untreated. An exposed tumor was observed with a diameter of approximately 8 cm located in the right breast.
