[A case of inoperable advanced gallbladder cancer that has maintained stable disease status for a long period with gemcitabine and cisplatin therapy].

We report a case of inoperable advanced gallbladder cancer that responded to treatment with gemcitabine (GEM) and cisplatin (CDDP) therapy. A 54-year-old woman was diagnosed in a nearby hospital with inoperable advanced gallbladder cancer (T4, N1, H0, P1, M(-): Stage IV b) with direct invasion to the liver. Therefore, chemotherapy was performed by TS-1. Two months later, however, the disease was found to have progressed, and she was referred to our hospital for further therapy. Combined chemotherapy with GEM 1,000 mg/m2 on days 1, 8 and 15 and CDDP 50 mg/m2 on day 1 was performed starting in June 2002. No side effects were observed after the first administration during hospitalization, so the treatment was continued on an outpatient basis. Her serum CEA and CA19-9 levels thereafter gradually decreased, and the disease stabilized for over a year. She has been able to maintain good quality of life without any severe adverse effects.

Fatality caused by self-bloodletting in a patient with factitious anemia.

Death by bloodletting among patients with factitious anemia has never been reported to our knowledge. We report the first known case. A 25-year-old woman with severe iron deficiency anemia confessed her habit of bloodletting at her first visit to our hospital, in March 1998. We prescribed oral iron and referred her to a psychiatrist. The diagnosis was borderline personality disorder. The psychiatrist began counseling the patient and prescribed a major tranquilizer. The patient's method of bloodletting was to insert an 18-gauge needle without syringe into her vein after inducing congestion in her arm. This method was considered to involve risk of death, because once the patient fell into a faint caused by blood loss, the bloodletting could not be stopped. Although we attempted to persuade the patient to stop bloodletting by this method, she died after self-bloodletting in September 1999. It is not known whether the death was intentional suicide or an accident.

[Chemotherapy with ubenimex corresponding to patient age and organ disorder for 18 cases of acute myelogeneous leukemia in elderly patients--effects, complications and long-term survival].

Ubenimex was concurrently administered to 18 elderly patients with acute myelocytic leukemia (AML), and a chemotherapy protocol was prepared corresponding to patient age and organ disorders. The dose-reduced protocol of the Japan Adult Leukemia Study Group (JALSG) '95 or aclarubicin 14 mg/m2 day 1-4, cytosine arabinoside 15 mg/m2 day 1-14, granulocyte colony stimulating factor (G-CSF) 150 micrograms/body day 1-14 (CAG therapy) were administered. In addition, ubenimex 30 mg/day was administered orally after induction of remission. As per the JALSG protocol for dose reduction when organ disorder is absent, 85% and 70% of the dose were administered to the patients aged 65-69 years and 70-74 years, respectively. For patients aged 75 years or more and patients with mild disorders of the heart, kidney, and liver, CAG therapy was administered. As a result, the complete remission (CR) rate was 67%, and the three-year survival rate was 32%. This protocol may be useful for elderly AML.

[Successful induction and long-term molecular remission with imatinib mesylate and chemotherapy in a case of Ph-positive acute lymphoblastic leukemia].

The patient was a 68-year-old woman who was diagnosed as having Ph-positive acute lymphoblastic leukemia (ALL). Complete remission (CR) was not obtained with the induction therapy of the Japan Adult Leukemia Study Group Protocol. We then considered administration of imatinib (ST1571). The institutional review board of our hospital approved this therapy, and we initiated the administration of imatinib 400 mg/day after obtaining written informed consent from the patient. At day 10 of the regimen, CR was achieved, treatment had to be discontinued RT-PCR showed no induction of detectable minor bcr-abl mRNA after three courses of consolidation chemotherapy combined with imatinib. We changed the administration protocol of Imatinib to two weeks out of every in four, weeks, and conducted 9 courses of consolidation chemotherapy. The negative result of RT-PCR has been maintained 10 months after diagnosis. The adverse effects were body weight gain and retaining pleural effusion, and these were controlled by the diuretics. The negative result of RT-PCR in Ph positive ALL after chemotherapy has rarely been reported, so the combination of imatinib and chemotherapy may be considered to be effective for Ph positive ALL.

[Management of cancer treatment-related diarrhea and constipation].

Digestive complications are frequent dose-limiting side-effect of chemotherapy. Diarrhea and constipation can affect quality of life and alter optimum treatment efficacy. The incidence and the severity of these toxicities have to be systematically evaluated in order to provide specific curative and preventive treatments. This review shows the recommended guidelines for the treatment of chemotherapy-induced diarrhea and the recent therapeutic approaches. The management of gastrointestinal graft-versus-host disease and neutropenic enterocolitis is also described. Prevention and early recognition is critical to avoid sever life-threatening complications and improve quality of life.

[A case responding to weekly paclitaxel (TXL) therapy as third line chemotherapy for scirrhous type gastric cancer].

A 67-year-old female was admitted to our hospital in May, 2001 for examination. She was diagnosed with advanced gastric cancer that was inoperable due to peritoneal dissemination. Seventeen courses of sequential MTX and 5-FU therapy, and 2 courses of TS-1 plus CDDP were carried out. A partial response (PR) and prolonged NC were obtained after these chemotherapies. However, pleural effusion and ascites appeared again, and we diagnosed progressive disease. As a third line chemotherapy for this patient, paclitaxel (TXL) was administered. Treatment consisted of two 3-week courses of paclitaxel 70 mg per m2 on day 1 of each week, with a 1-week break between the courses. Two weeks after the start of this therapy, pleural effusion and ascites had completely disappeared. Paclitaxel is considered to be promising for advanced gastric cancers, as second or third line chemotherapy with paclitaxel for patients with inoperable gastric cancer seems to be effective in improving QOL.

[A case of irinotecan-resistant colon cancer responding to chronotherapy with oxaliplatin, 5-FU, l-LV].

We report a case of irinotecan-resistant colon cancer responding to chronotherapy with oxaliplatin (L-OHP), 5-FU, l-LV (l-Leucovorin). A 72-year-old man was examined at a certain hospital because of constipation and appetite loss. Chest computed tomography (CT) revealed lung metastases, and abdominal CT revealed liver metastases. He was then referred to our hospital. A colonoscopy revealed type 2 tumor in the colon, at the hepatic flexure. We diagnosed adenocarcinoma of the colon with metastases to the liver and lung. Resection of the primary lesion was performed, and chemotherapy consisting of systemic administration of CPT-11, 5-FU and l-LV was performed. After 2 courses of combined treatment with CPT-11/5-FU/l-LV, CT revealed considerable reduction of the metastatic tumors. However, after 3 courses of combined treatment, progressive disease was observed and new brain and bone metastases were detected. We imported and used a non-approved/pending drug, oxaliplatin from the Remedy and Health Corporation, with informed consent from the patient and his family and our clinical ethics committee. Chronotherapeutic schedules have been performed, from which the safety and activity of oxaliplatin against advanced colorectal cancer was reported. Our patient received a 5-day course of chronomodulated 5-FU and l-LV (750 and 300 mg/body/day, respectively; peak delivery rate at AM 4:00 hours) with L-OHP on the first day of each course (100 mg/body, as a 6-hour infusion). Each course was again repeated every 21 days. A partial response was observed in the liver and lung metastases. These results indicate that chronomodulated 5-FU and LV with L-OHP therapy could be an effective regimen for cases of irinotecan-resistant colon cancer.

[Successful treatment after acute promyelocytic leukemia (APL) syndrome of relapsed API with arsenic trioxide].

A 52-year-old female was diagnosed with relapsed APL in 2000. After obtaining informed consent, we administered 10 mg/day of arsenic trioxide intravenously. The complications were vomiting, increased transaminase and ATRA syndrome which included high fever, retention of body fluid, pleural effusion, pericardial effusion and respiratory failure from day 16. Administration of steroid and low dose chemotherapy (DNR 60 mg x day 1-2, BH-AC 250 mg x day 1-2) with arsenic was effective for APL syndrome, and complete remission (CR) was obtained at day 35 and PML-RAR mRNA became negative. After obtaining CR, consolidation chemotherapy was conducted and the patient was maintained the CR for more than 18 months. Although arsenic trioxide may be effective for relapsed APL, sufficient caution is needed because of the possibility of various complications.

[A case of undifferentiated bladder carcinoma with axilla lymph node metastasis successfully treated with gemcitabine and cisplatin].

A 68-year-old man diagnosed with undifferentiated bladder carcinoma underwent radical cystectomy in another hospital. His clinical staging was T3bN2M0. Four months after the operation, he had right axilla lymph node swelling and pain. He was referred to our hospital, and diagnosed with axilla lymph node metastasis of bladder carcinoma based on test results. Four cycles of GEM and CDDP chemotherapy were performed. After the chemotherapy, the metastatic focus disappeared completely from the CT scan, and the case was considered to be CR. It is suggested that this combination therapy may be useful for bladder carcinoma in advanced or metastatic stages.
