A 21-year-old man with an osteosarcoma in the proximal tibia was treated by amputation, radio- and chemotherapy. Besides pulmonary metastases, intramuscular metastases repeatedly developed. Cell culture studies of pulmonary and muscular tumors showed different sensitivity patterns for cytostatic drugs; the therapy may have selected different subpopulations of the primary tumor.

A 21 year old caucasian male, who was admitted to the medicine service for respiratory problems and hematemesis was ultimately diagnosed as having metastatic choriocarcinoma. Plasma samples were analyzed for prothrombin time (PT), activated partial thromboplastin time (APTT), platelets, and clot activation time for fibrinogen (FIB), and coagulation factors II, V, VII, VIII, X and XII. Abnormal clotting parameters included thrombocytopenia, PT, APTT, FIB, factors II, V, VII, and X. The coagulation abnormalities indicate the patient was in a state of consumption coagulopathy possibly induced by hepatic metastasis of the primary tumor.

A 21-year-old man had undergone central bisegmentectomy of the liver due to fibrolamellar carcinoma (FLC). Twice, 24 and 30 months after the first operation, lymph node metastases were removed. We have reported this case previously and this is the second report of the same case. Forty-two months after the second operation to remove lymph node metastases, a recurrence occurred in the rectum and was excised. However, the tumor also recurred in the residual liver. The patient underwent hepatectomy for a palliative purpose but died 16 months after the last operation. Histopathologically, the primary tumor was diagnosed as pure FLC, but the lymph node metastases had foci of the common hepatocellular carcinoma (HCC) mixed with FLC. In contrast, the recurrent tumors in the rectum and the residual liver showed the histopathological features of common HCC. Thus, during repeated recurrences, histopathological features changed from pure FLC to common HCC.

Despite highly efficacious chemotherapy, patients with osteosarcomas still have a poor prognosis if adequate surgical control cannot be obtained. We applied high-activity Sm-153-EDTMP therapy within a multimodal therapy concept to improve local control of an unresectable osteosarcoma with poor response to initial polychemotherapy. A 21-year-old woman with an extended, unresectable pelvic osteosarcoma and multiple pulmonary metastases was treated with high-activity of Sm-153- EDTMP (150 MBq/kg BW, total 8.1 GBq). Afterwards external radiotherapy of the primary tumor site was performed and polychemotherapy was continued, followed by autologous peripheral blood stem cell reinfusion. Within 48 h after Sm-153-EDTMP application the patient had complete pain relief. After three weeks the response was documented by 3-phase Tc-99m-MDP bone scintigraphy (primary tumor and metastases: decreased tracer uptake), whole-body F-18-FDG-PET (primary tumor and metastases: diminution of glucose metabolism) and thoracic CT (metastases: reduction of size). The present case warrants further evaluation of feasibility and efficacy of this multimodal therapy combination of high-activity Sm-153-EDTMP therapy, external radiation, polychemotherapy and stem cell support for unresectable osteosarcomas.

A 21-month-old girl was admitted to our Department of Pediatrics to diagnose febrile states lasting for previous two weeks, anemia and increased erythrocyte sedimentation rate (ESR - erythrocyte sedimentation rate). The physical examination revealed the paleness of skin and oral mucosa, silent systolic murmur and hypotrophic constitution. The laboratory tests confirmed anemia and showed increased ESR and moderately increased C Reactive Protein (CRP - C Reactive Protein). The blood culture, the urine culture, the stool culture, the tests of the stool in direction of parasites and the serologic tests carried out in direction of infection caused by Toxoplasma ghondi, Mycoplasma pneumoniae, HAV, HCV, CMV, EBV and Parvovirus B19 were all negative. The chest X-ray picture and ultrasonographic examination of abdomen showed no abnormality. The consulting hematologist carried the bone marrow biopsy out--the bone marrow was poorly cellular. The urinary level of catecholamines and plasma level of neuron-specific enolase (NSE) were greatly increased. The computer tomography scan of head, neck, thorax and abdomen did not confirmed the presence of the tumor. Nevertheless the bone scintigraphy demonstrated the presence of foci of abnormally increased activity in left femur and the right hip-bone--pathognomonic of metastatic disease. During the hospitalization we did not observe the fever, but only the deepening anemia, weakness, irritability, limping and the presence of spectacle-shaped hematomas. The blood parameters temporarily were normal after blood transfusion. The patient was transmitted to the Department of Children's Oncology and Hematology. The trepanobiopsy of the bone marrow showed the presence of metastases of neuroblastoma. The magnetic resonance imaging (MRI) was made, but it did not revealed the presence of the primary tumor. The patient underwent a course of chemotherapy.
