A 65-year-old woman was admitted to our hospital with the diagnosis of gallbladder tumor. Right extended hepatic lobectomy plus lymph node dissection of the hepatoduodenal ligament and left hepaticojejunostomy with Roux-en-Y reconstruction was performed in July, 1993. The gallbladder tumor was histologically proven to be squamous cell carcinoma. Seventeen months later, the patient experienced dyspnea and pitting edema of the lower legs and was admitted, in December 1994, with a diagnosis of heart failure. Despite intensive cardiac support, she died 12 days after the second admission. Autopsy revealed multiple cardiac tumors in the left and right ventricles, left atrium, left coronary artery, and left diaphragm. Histologically, these tumors were shown to be squamous cell carcinoma, considered to have metastasized from the primary gallbladder carcinoma. As neither local recurrence of the gallbladder carcinoma nor any lymph node metastasis was found, the cardiac metastasis of the gallbladder carcinoma may have occurred via the hematogenous route. Although rare, this route of cardiac metastasis of gallbladder carcinoma may be an important aspect of distant metastasis, which should be monitored for during follow-up after resection of the primary tumor.

We report a case of cardiac synovial sarcoma, a very rare primary tumor of the heart. The patient was a 29-year-old man with chief complaint of dyspnea. On echocardiography, a tumor 42 mm in diameter occupying the most space of the left atrium was found. The tumor was obstructed the opening of the mitral valve. He was diagnosed with heart failure due to disturbance of the pulmonary venous return and hemodynamic mitral valve stenosis, and underwent surgery. The tumor was a 5-cm sphere originating in the left atrial posterior wall, and was covered with a sheath and solid. The atrial posterior wall was covered with a peel that appeared to be tumor tissue, and this tissue expanded toward the openings of the pulmonary veins bilaterally and the posterior cusp of the mitral valve. The tumor was resected together with the posterior wall. On pathologic examination, the tumor was diagnosed as a synovial sarcoma. Since no other primary focus was found, this tumor was judged to be a primary sarcoma of the heart. The patient was discharged with elimination of symptoms. The sarcoma recurred after 4 months, and the patient underwent a second operation. The recurrent tumor began from the site of resection of the previous operation and expanded up to the inferior pulmonary veins bilaterally. A wide area of the left atrial wall including the tumor was resected, and he was discharged again. The sarcoma recurred again, and he died of progression of heart failure and aggravation of general conditions after 8 months from the first operation.

This report describes an extremely rare combination of mediastinal germ cell tumor and visceral hemangiomatosis in a 17-year-old boy who initially presented with chest pain and dyspnea. He was treated with chemotherapy consisting of cisplatin, cyclophosphamide, bleomycin, vinblastine, and dactinomycin followed by surgery. Multiple low-density nodules developed in the spleen three weeks later, suggesting metastases from the primary tumor, but the resected specimen showed cavernous hemangiomas within the splenic parenchyma. The patient died of recurrence of germ cell tumor 19 months after the initial treatment. Postmortem examination disclosed multiple hemangiomas in the lung and liver similar to those in the spleen.

A 81-year-old man presented with massive hemoptysis and dyspnea. Results of chest radiography and computer tomography were highly suspicious for a large right-sided tumor of the bronchus with impression of the right main bronchus. Because of clinical worsening the patient was transferred to our department of pulmonology. The patient died of unappeasable hemoptysis the next day. At autopsy we found a 2-cm-diameter tumor of the proximal trachea as the source of massive bleeding and blood aspiration. Histological examination confirmed the tumor to be an epithelioid angiosarcoma of the trachea, which was a primary as no other tumor manifestation was detected. The entity of epithelioid angiosarcoma as a primary tumor of the trachea, to our knowledge, has not yet been reported.

Metastatic involvement of the laryngeal is very rare, with around 150 cases reported to the literature. In eight of these cases, the primary tumor was a colon adenocarcinoma. We report the case of a 80 year-old woman treated of a colloid adenocarcinoma of 7 years earlier, referred to us for chronic and progressive dyspnea. Endoscopic examination showed a subglottic spherical mass, which caused an important compromise of the respiratory airway. Tomographic studies revealed also a thyroid mass. The patient was treated with a tracheostomy, resection of the subglottic mass (with intraoperative diagnosis of "mucin producing tumor"), and total thyroidectomy. The final pathologic diagnosis of the subglottic mass was a metastasis of colloid adenocarcinoma of the colon. In the literature reviewed there are no previous reports of metastatic involvement of the larynx with this type of colon adenocarcinoma. We discuss the clinical and radiological findings, and therapeutic options for metastasis to the larynx, as well as pathological differential diagnosis.

JM216 is an orally administered platinum analogue. We undertook this study to determine the maximally tolerated dose (MTD) of JM216 when administered with concomitant radiotherapy to the chest (200 cGy daily, 5 x/week) in patients with locoregionally advanced non-small cell lung (NSCLC) or esophageal cancer. Patients were excluded for inadequate bone marrow reserve, prior radiotherapy to the primary tumor or previous treatment with platinum drugs. A dose-limiting toxicity (DLT) was defined using the National Cancer Institute (NCI) Common Toxicity Criteria (CTC) and consisted of grade > or = 2 renal, hepatic, cardiac, or pulmonary toxicity or grade > or = 3 hematologic, neurological, or gastrointestinal toxicity. A total of 23 patients were registered; two never received treatment and are excluded from analyses. Six patients were treated at a dose of 30 mg/m2/day for 5 days with two grade 2 DLT's: cough (1 pt) and elevated trans-aminases (1 pt). Seven evaluable patients were treated at 60 mg/m2/day and seven experienced grade 3 or 4 toxicity, five related to myelosuppression. The dose was then reduced to 45 mg/m2/d. Eight patients were evaluable for toxicity, of which 5 experienced DLT: myelosuppression (3 pts), esophagitis (2 pts), dyspnea (1 pt), and elevated creatinine (1 pt). Fourteen patients were evaluable for efficacy, of which 6 had an objective response, including one complete response. The recommended phase II dose of JM216 with concurrent radiation therapy is 30 mg/m2/d for 5 days. The major DLT is myelosuppression with only limited increased toxicity within the field of radiation. This conceivably may limit the use of JM216 as a radiation sensitizer.

Angiosarcomas are rare malignant vascular tumors with a high rate of metastasis involving lungs (most commonly), liver, regional lymph nodes, bone, and other sites. In this study, we have reviewed the clinical presentation and histopathology of 21 cases of extracutaneous angiosarcoma metastatic to the lungs. Tumors with exclusively pleural involvement were excluded. Patients presented with dyspnea, chest pain, and/or hemoptysis lasting a few weeks to months. Radiologically, the most common finding comprised multiple peripheral lung nodules (57%), often accompanied by infiltrates. For 11 cases (52%), the primary tumor was not identified at the time of presentation. Vasoformative areas were identified in 15 cases (71%). Nine cases comprised spindle cells (43%), two contained epithelioid cells (9.5%), and 10 consisted of both spindle and epithelioid cells (48%). Nuclear pleomorphism was at least moderate in all cases. However, five tumors contained regions of minimal nuclear atypia. Hemorrhage, siderophages, and fibrosis were commonly present. Immunohistochemical staining (IHS) was performed on 14 cases. Thirteen tumors showed reactivity for vascular markers. Tumor cells reacted for Von Willebrand factor in 13 of 14 cases, and CD31 and CD34 were each positive in 2/2 cases. Two cases (of nine examined) also expressed cytokeratins. Because the tumor often first presented in the lungs before the primary sarcoma was identified, the clinical impression included both benign and malignant entities. For patients with primary cardiac tumors, symptoms referable to the primary tumor complicated the clinical presentation, and radiologic evaluation supported a clinical diagnostic impression of non-neoplastic pericarditis. Thus, angiosarcoma in the lung may elude diagnosis until histopathologic evaluation of the lung biopsy.

TS-1 is a new, oral anticancer agent composed of two modulators, gimeracil (CDHP) and oteracil potassium (Oxo) are mixed with tegafur in a ratio of 1:0.4:1. We report one case of advanced gastric cancer with lung and lymph node metastases that completely responded to TS-1. A 71-year-old woman was admitted to our hospital because of breathlessness. A diagnosis of advanced gastric cancer with extensive lymph node metastases and multiple pulmonary metastases was made. One hundred mg/body/day of TS-1 was orally administrated for 4 weeks. A partial response (PR) was obtained after the first course with regression of multiple pulmonary metastases. After 1 drug-free week, the second course was administered with 120 mg/body/day of TS-1 for 4 weeks. After two courses, the primary tumor was reduced to an ulcer scar with pathological confirmation of a complete disappearance of the cancer tissue. Moreover, computed tomography (CT) showed a complete regression of the extensive lymph node and diffuse lung metastases, for a complete response (CR). The serum level of CEA was reduced from 172.7 ng/ml to 8.1 ng/ml after TS-1 treatment. As for adverse events, only pigmentation of the skin and Grade 2 oral aphta were observed.

Primary malignant tumors of the small intestine are rare. Malignant gastrointestinal stromal tumors are the third most common neoplasm among primary malignant small bowel tumors. A 56-year-old woman was admitted to our hospital because of appetite loss and dyspnea with movement. On admission, physical examination revealed severe anemia in her conjunctiva and a tumor in her left abdomen. Her hemoglobin level was 6.2 g/dL and other laboratory data were normal. Abdominal ultrasonograms and computed tomograms revealed a 55 x 70-mm heterogeneous mass and multiple low-density masses in the liver. Superior mesenteric arteriograms revealed a hypervascular tumor fed by the jejunal arteries. A malignant gastrointestinal stromal tumor arising from the jejunum with liver metastases was suspected. Partial resection of the affected jejunum and left trisegmentectomy of the liver were performed. The resected primary tumor was 120 x 45 x 65 mm. The tumor was mainly submucosal, but extended outside the jejunum; it was elastically firm and multiloculated. A small ulcer was seen on the mucosal side. The metastatic liver tumors were solid or cystic with diameters of 20 to 40 mm. Histopathological examination revealed that the tumors were characterized by fascicular proliferation of spindle-shaped cells. Immunohistochemical staining was positive for CD34 and c-kit, and negative for S-100 protein and smooth muscle actin. This case was a malignant gastrointestinal stromal tumor originating in the jejunum with liver metastases. The primary tumor and liver metastases were successfully resected simultaneously.

A 38-year-old woman presented to our hospital with the chief complaint of dyspnea. A chest radiograph showed pleural effusion of the right lung and a CT scan revealed liver metastasis. A tumor biopsy done under bronchoscopy revealed large-cell carcinoma of the lungs. She was given 4 courses of a combination therapy consisting of CDDP (80 mg/m2) and vinorelbine (25 mg/m2). The primary tumor in the right lung and liver metastasis were markedly reduced in size and a partial response was obtained. The combination therapy of CDDP and vinorelbine may become a standard chemotherapy for advanced non-small cell lung cancer.
