A woman with multiple bone metastases three years after radical mastectomy for right breast carcinoma was admitted to the Department of Radiology, National Hakodate Hospital. She underwent radiotherapy for the metastasis of the seventh cervical vertebra, and her back pain decreased. Six courses of combination chemotherapy were undertaken using MTX, CPM, 5-FU, VCR and predonine, but her multiple bone metastases progressed. Then, she was treated with chemo-endocrine therapy which consisted of tamoxifen 30 mg daily and CPM 100 mg daily given orally. Two months later, UFT 400 mg daily was administered instead of CPM. This therapy has been effective for 8 years, and she has remained alive and well. On bone scintigram, the abnormal radioisotope uptake almost disappeared. Also, X-ray film showed no osteolytic change and no destruction of bone. These results suggest that it is important to select a suitable combination of drugs for each patient with advanced breast carcinoma.

Radical surgery in malignant bone tumors can either be limited by anatomical structures or seems inadequate in the palliative stabilization of bone metastases. Incomplete removal of the tumor and stabilization by compound osteosynthesis or endoprosthesis contains two problems: 1) the wide spread of malignant cells by manipulation in the tumor bearing area; 2) progressive destruction of bone due to remaining tumor. To overcome these problems we developed methotrexate bone cement (MTX-Palacos) with the aim to obtain high local concentrations of methotrexate in order to destroy remaining tumor cells and avoid systemic side effects. In vitro studies showed that methotrexate is released continuously from this cement without relevant changes of its biomechanical properties. Animal studies with transplanted osteosarcomas and mamma carcinomas in mice showed a considerable decrease of tumor growth when a plug of MTX-Palacos was inserted in the center of the tumor. Histological findings showed that in the surroundings of the plug the tumor was destroyed considerably contrary to normal bone cement which had no effect on the tumor at all. The results are discussed with regard to clinical application of MTX-Palacos.

An advanced gastric cancer patient with multiple retroperitoneal lymph node metastases and bone metastases was treated with sequential MTX and 5-FU. Complete response was obtained against both gastric primary lesion and retroperitoneal lymph nodes observed endoscopically and by computed tomography. Partial response was obtained against bone metastases observed by bone scintigraphy. Side effects of the chemotherapy were not observed.

We report a 47-year-old female patient who was suffering from severe DIC due to multiple bone metastases. This patient was treated weekly with an intraarterial 5-FU (500 mg) and MTX (100 mg) including AT-II by a subcutaneously implanted port system placed into her abdominal aorta. Furthermore, she was administered tegafur/uracil (400 mg/day) 5 days weekly for pharmacokinetic modulating chemotherapy (PMC). After three courses of PMC treatment, DIC was resolved and the tumor marker was reduced. However, after 22 courses of this regimen, DIC suddenly recurred. As second line chemotherapy, we then administered paclitaxel (80 mg) in place of CDDP. After five courses of this second line chemotherapy, DIC recovered and the tumor marker was again decreased. We concluded that this chemotherapy is effective for advanced gastric cancer complicated with bone metastasis and DIC from the standpoint of toxicities, antitumor effect and QOL of the patient.

A 63-year-old woman presented with an abnormal serum alkaline phosphatase (ALP) level. Computed tomography (CT) scan of the abdomen and pelvis and radioisotope (RI) examination led to a strong suspicion of systemic bone metastatic tumors, although the origin was not known. Biopsies from bone metastatic lesions in the left ilium were performed under CT scan, and signet-ring cell carcinoma cells were detected pathologically. Also, a 0-IIc-like lesion was observed endoscopically in the stomach, and signet-ring cell carcinoma cells were also detected histologically. The patient's platelet (Plt) levels were reduced and slight bleeding from the gingiva was detected when she brushed her teeth. Both the stomach and the bone metastatic lesions exhibited a gastric phenotype (G type) phenotypically. From these findings, we diagnosed the patient as having advanced (inoperable) stomach cancer with multiple bone metastases; she also exhibited disseminated intravascular coagulation (DIC). We treated her with sequential methotrexate and 5-fluorouracil (sequential MTX/5-FU) therapy after obtaining her informed consent. After six cycles of the chemotherapy, the abnormal ALP and Plt levels were alleviated. At present, she is receiving weekly sequential MTX/5-FU therapy at the outpatient oncology unit; she has been receiving the therapy for about 7 months since the detection of the bone metastases and has had a total of 17 cycles. In conclusion, sequential MTX/5-FU therapy was effective for a patient with G-type signet-ring cell carcinoma of the stomach with bone metastases, suggesting that the phenotypic classification may be one of the useful markers for prediction of the effectiveness of chemotherapy in patients with inoperable advanced stomach cancer.
