Until the 1970s, the survival rate of osteosarcoma patients was less than 20%. By the 1990s, this had improved to 60% to 70%, and limb-sparing procedures have replaced amputation in many patients thanks to effective combination therapy. Neoadjuvant chemotherapy has become an accepted practice in the majority of institutions using protocols which include
MTX
, ADR, BCD and CDDP as the most active agents against this disease. Newer agents, particularly IFM and ETP, are increasingly incorporated into complex regimens. While several studies have reported multivariate analyses to identify prognostic factors, the histologic response to preoperative chemotherapy remains the most important prognostic factor. Pulmonary metastases are the primary cause of death in patients with osteosarcoma. Although current treatment regimens allow effective salvage therapy for the patients with pulmonary
metastases
, the actuarial survival rate is 30%. A more effective systemic treatment for those patients is needed. The current management of osteosarcoma is critically reviewed and a treatment strategy is proposed for discussion.

There have been few effective chemotherapeutic regimens for advanced gastric cancer with liver and intra-abdominal lymph node metastasis. A 78-year-old male patient was admitted to our hospital because of anorexia and abdominal discomfort. Gastroendoscopy showed a type 4 advanced gastric cancer in the antrum of the stomach. Histological study of biopsy specimens from the tumor revealed poorly differentiated adenocarcinoma. Examination by computed tomography and ultrasonography showed swollen paraaortic lymph nodes and liver metastasis. He was diagnosed as having advanced gastric cancer with liver and lymph node metastasis. This patient was treated weekly with an intraarterial 5-FU (500 mg) and
MTX
(100 mg) including AT-II by subcutaneously implanted port system placed into the celiac artery. Furthermore, he was administered tegafur/uracil (400 mg/day) 5 days weekly as pharmacokinetic modulating chemotherapy (PMC). After ten courses of treatment with PMC, the liver and lymph node
metastases
were reduced in size. This therapy was considered to be an effective treatment for advanced gastric cancer with liver and lymph node metastasis. The theoretical purpose of hypertensive chemotherapy used together with injection of angiotensin-II is to increase the delivery of anticancer drug to the target tumor tissue by increasing the blood flow in the tumor. We conclude that this chemotherapy is effective in cases of advanced gastric cancer with liver and lymph node metastasis from the viewpoints of toxicities, antitumor effect and QOL of the patient.

We report a case of advanced gastric cancer that responded to docetaxel with low-dose 5-FU and cisplatin combination chemotherapy after becoming chemoresistant to M-FLP. A 52-year-old male was diagnosed with type 3 gastric cancer of angulus (poorly differentiated adenocarcinoma) with left neck, Virchow, mediastinal and abdominal lymph nodes
metastases
. The patient was treated with 5 courses of M-FLP (
MTX
+ 5-FU + LV + CDDP), and the effect of this therapy was PR, but the tumor was chemoresistant to the sixth course of this therapy. After 7 courses of M-FLP, docetaxel (TXT) with low-dose FP (5-FU + CDDP) was administered to the patient as second-line chemotherapy. After 2 courses of TXT with low-dose FP, the gastric cancer and metastatic lymph nodes were remarkably reduced and the effect of this therapy was PR. The toxic events were anemia (grade 2) and leukopenia (grade 3), which were treated with G-CSF. CDDP and 5-FU based regimens are considered as the first-line chemotherapy for metastatic advanced gastric cancer in Japan; however, a second-line chemotherapy has not been established. As in this case, a TXT based regimen is effective and well tolerated therapy as a second-line chemotherapy for metastatic gastric cancer after prior exposure to CDDP and 5-FU.

We describe our experience with a patient who had undifferentiated gastric carcinoma with extensive lymph node metastasis, including para-aortic lymph-node metastasis, and had a complete response to induction therapy with methotrexate plus 5-fluorouracil (sequential therapy with
MTX
, 5-FU, and Leucovorin) and secondary treatment with oral TS-1. The patient was a 71-year-old woman with a massive gastric tumor (signet ring cell carcinoma), occupying most of the stomach. A computed tomographic (CT) scan revealed para-aortic, celiac, and common hepatic lymph-node
metastases
. Stage IV disease was diagnosed. Palliative total gastrectomy was performed to control bleeding and to improve oral intake of food. Two courses of induction therapy with
MTX
, 5-FU, and Leucovorin were started 3 weeks after surgery. A CT scan revealed residual lymph node metastasis. The response was assessed to be no change, but the levels of carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 19-9 improved from 7,028 ng/ml and 726 U/ml 3 weeks after surgery to 2,832 ng/ml and 281 U/ml, respectively. Secondary treatment with oral TS-1 was begun, and a CT scan showed distinct shrinkage of lymph-node
metastases
. There was no serious toxicity. The levels of CEA and CA19-9 decreased markedly to 2.9 ng/ml and 16 U/ml, respectively, about 6 months after surgery and remained at 3.7 ng/ml and 16 U/ml, respectively, about 1 year after surgery.

Curative resection is considered to be a standard therapy for gastric cancer with localized peritoneal
metastases
. For tumors with diffuse dissemination, chemotherapy may play a major role, however, the benefits of reduction surgery and standard chemotherapy have not yet been clarified. Median survival time after reduction surgery was reported to be 4-13 months for patients diagnosed by surgery and/or CT and 5-6 months for chemotherapy for those diagnosed by CT alone. Reduction surgery has a high risk, with a morbidity of 12-44% and a mortality of 3-14%. Palliative surgery should be indicated for stenosis or bleeding due to primary tumors. 5-FU,
MTX
-5-FU, TS-1, paclitaxel, and their combination are candidates for practice and clinical trials. It is important to evaluate the severity of peritoneal dissemination by diagnostic laparoscopy or laparotomy for decision making.

We examined safety and efficacy of hypotonic CDDP intraperitoneal administration followed by systemic chemotherapy using
MTX
/5-FU and UFT. Between 1998 and 2004, seven patients who had histologically proven gastric adenocarcinoma with peritoneal
metastases
underwent palliative gastrectomy at Niigata University Medical Hospital. For residual peritoneal tumors, 100 mg/body of CDDP diluted with distilled water was intraperitoneally administered to the patients before closure of abdominal wall and was drained 30 to 60 minutes after administration. During the postoperative period, a patient suffered from intraperitoneal abscess and another patient had a renal dysfunction with an increasing level of serum Cr (2.1 mg/dl). As adverse effects of the following systemic chemotherapy, three patients had grade 3 anemia and one had grade 3 leukopenia. The median time to progression was 109 days and the median survival time was 248 days. Although intraperitoneal CDDP administration is safe to be carried out intraoperatively, the effect on survival is not better than new anticancer drugs, such as TS-1 and paclitaxel.

We describe two patients, who suffered from Stage IV gastric poorly differentiated adenocarcinoma and underwent palliative total gastrectomy, were treated by sequential chemotherapy and achieved long term-survival. The first patient was a 55-year-old male with peritoneal dissemination. After total gastrectomy, he was treated with methotrexate-5-fluorouracil (
MTX
/5-FU) sequential therapy for 5 months, S-1 single-agent therapy for 4 years and weekly paclitaxel (PTX) therapy for 9 months. He is being treated with irinotecan (CPT-11) therapy as an outpatient now, and has achieved 5 year 8-month survival. The second patient was a 60-year-old female. We observed unresectable
metastases
around the pancreas, aorta, and transverse mesocolon. She was treated with S-1 single-agent therapy for 1 year 10 months,
MTX
/5-FU sequential therapy for 9 months. She is now receiving weekly PTX therapy for 3 months as an outpatient and has achieved 2 year 11-month survival.

We recently identified a new tumor (VM-M3), which arose spontaneously in the brain of an inbred VM mouse. When grown outside the brain, the VM-M3 tumor expresses all major biological processes of metastasis to include local invasion, intravasation, immune system survival, extravasation, and
secondary tumor
formation involving lung, liver, kidney, spleen and brain. The VM-M3 tumor also expresses multiple properties of macrophage-like cells similar to those described previously in numerous human metastatic cancers suggesting that the VM-M3 model will be useful for studying most types of
metastatic cancer
, regardless of tissue origin. VM-M3 tumor cells, expressing firefly luciferase (VM-M3/Fluc), were grown subcutaneously in the immunocompetent and syngeneic VM mouse host. The antimetastatic effects of methotrexate (
MTX
; 25 mg/kg) and cisplatin (10-15 mg/kg) were evaluated following i.p. injections administered once/wk for 3 weeks. Bioluminescent imaging was used to measure VM-M3/Fluc growth and metastasis. All (12/12) control mice developed systemic cancer within 21 days of subcutaneous VM-M3/Fluc implantation. Although methotrexate did not inhibit VM-M3/Fluc primary tumor growth, it reduced lung and liver metastasis by 50% and completely inhibited metastasis to kidneys, spleen and brain. Cisplatin significantly reduced primary tumor growth, blocked metastasis to lung, liver, kidneys, spleen and brain, and significantly increased survival in all treated animals. Our findings show that the response of the VM-M3/Fluc tumor to
MTX
and cisplatin is similar to that reported in humans with
metastatic disease
. These findings indicate that the VM-M3/Fluc tumor is a reliable preclinical model for evaluating antimetastatic cancer therapies and underlying control pathways.

We present the first reported case of a child with familial expansile osteolysis syndrome (FEO) who developed osteogenic sarcoma (OS) of the iliac bone. A 17-year-old adolescent presented with pain and a mass on the left pelvis. He was from a family with several members who had been diagnosed with FEO, from which he also suffered. The median life expectancy of affected members of the family was reported as 25 to 30 years, with death ensuing as a result of various respiratory and cardiac complications of severe skeletal deformations, characteristic of increased bone turnover as seen in FEO. Biopsy of the patient's mass revealed chondroblastic OS. He was treated according to the P9754 protocol for patients with newly diagnosed nonmetastatic OS. Chemotherapy consisted of HD-
MTX
, ifosfomide, doxorubicin, and cisplatin. Complete resection of the tumor was carried out, but the patient subsequently developed
metastatic disease
and died (histologic response to neoadjuvant chemotherapy-85%). The patient's alkaline phosphatase level that was highly elevated before the start of chemotherapy, dropped significantly during treatment, with repeated elevation soon after definitive surgery, while he was recuperating and not on treatment. We speculate that chemotherapy affected not only the malignant cells of OS but normal osteoblasts as well, with a decreasing level of alkaline phosphatase even in the absence of any clinical and radiographic signs of OS. We also think that increased bone turnover, characteristic of a condition such as FEO, may facilitate de novo development of OS.

A 44-year-old man visited a nearby hospital because of severe headache. Brain MRI revealed a subdural hematoma, and he was transferred to the Department of Neurosurgery of our hospital. Burr hole surgery was performed on the second day of hospitalization because of an enlargement of the hematoma. Laboratory data on admission showed the presence of a disseminated intravascular coagulation(DIC). Bone marrow aspiration revealed
metastases
of signet ring cell carcinoma, and abdominalCT showed gastric cancer. He was diagnosed as having DIC with bone marrow metastases of advanced gastric cancer. Despite anti-DIC therapy and blood transfusion, his systemic bleeding tendency was not improved. The neurosurgeon therefore consulted with a palliative care team. Since the patient was still young, we considered that he should be treated with anti-cancer drugs. At first, his family did not accept chemotherapy because they were pessimistic about his prognosis. However, after he regained his consciousness, we were able to perform sequential
MTX
and 5-FU therapy with the consent of the patient and his family. The therapy was successful, and he recovered from DIC and was discharged on the 57th hospital day.
