RESUMO
Leiomyosarcoma is a rare tumor of mesenchymal origin usually affecting the inferior vena cava. Early diagnosis is essential before surgical resection, which is the only therapeutic modality that prolongs patients' survival. Ultrasonography, computer tomography, and magnetic resonance imaging are the main imaging modalities in this case. Combined with guided biopsies, they form the mainstay of reliable diagnosis. We report a case with retroperitoneal tumor arising from the middle segment of the inferior vena cava. Radiological examination revealed retroperitoneal tumor and helped to choose surgical treatment. Histopathological examination confirmed the diagnosis of leiomyosarcoma of the inferior vena cava.

BACKGROUND: We evaluated efficacy and safety of recombinant granulocyte-colony stimulating factor (rGCSF) used as primary prophylaxis to prevent neutropenia and neutropenia-related complications induced by docetaxel and doxorubicin chemotherapy in patients with metastatic breast cancer. PATIENTS AND METHODS: Three centers in Lithuania enrolled 36 patients who received rGCSF (5 microg/kg/d) on day 2 of each 21-day chemotherapy with docetaxel 75 mg/m(2) and doxorubicin 50 mg/m(2) (AT) starting in the first cycle. Treatment regimen was repeated for up to six cycles. RESULTS: Leukocytosis, bone pain, and headache were the most frequent adverse events, with incidence rates of 22%, 19%, and 8%, respectively. Adverse events were typical for rGCSF in this patient population. Overall incidence rate of febrile neutropenia was 14%. The mean duration of febrile neutropenia episodes across cycles was 2.14 days. Incidence of chemotherapy delay was 2%. There was no reduction in chemotherapy dose due to expected toxicity or side effects. Intravenous antibiotics for the treatment of febrile neutropenia were needed in 19% of cases. Quality-of-life assessment shows a significant improvement in emotional functioning and a significant decrease in pain score. The efficacy profile of rGCSF observed in the present study was comparable with that of other rGCSF products previously described in the published scientific literature. CONCLUSIONS: The primary prophylaxis of neutropenia and its complications by rGCSF was safe and effective for women with metastatic breast cancer who received chemotherapy with docetaxel and doxorubicin.

This case report presents a very aggressive course of amelanotic nodular melanoma during pregnancy resulting in death five months after delivery. A 34 year-old Caucasian woman at 19th week of the second pregnancy was diagnosed having amelanotic nodular melanoma (tumor thickness - 2.5 mm) with metastases to the regional right inguinal lymph node. Amelanotic nodular melanoma represents malignant melanocytic tumor of the skin, which clinically mimics a variety of benign and malignant skin conditions and therefore commonly leads to delayed diagnosis. Though primary tumor was excised immediately, other treatment procedures as radical lymphadenectomy and chemotherapy were delayed, and immunotherapy was not given totally. At the 29th week of pregnancy, the woman via naturalem delivered a healthy female child, and the chemotherapy was started. Since pregnancy limits the prescription of immunotherapy and chemotherapy, the prognosis for melanoma during pregnancy detected later than in the second stage is poor and can be illustrated by our reported case. Such patients seems to be at higher risk to develop metastasis of melanoma in the internal organs and occasionally even in the fetus; therefore, they should be timely informed about that.

The main cause of death in patients with gastric cancer is disease dissemination. It is not clear why gastric cancer metastasizes to different organs. Early detection and destruction of circulating malignant cells before developing metastases may markedly improve survival of these patients. Krukenberg tumors (metastases of non-gynecological origin in the ovaries) usually are circular cell carcinomas of gastric cancer. Bone metastases of gastric cancer are rare, but if they are diagnosed, patients survive only 2-5 months on the average. Disseminated bone marrow metastases from gastric cancer do not always show the sudden course of the disease, but hematological complications are signs of poor prognosis. Hematological paraneoplastic disorders can be miscellaneous: they usually manifest as anemia of various origin, as leucocytosis in half of the patients, as leukemoid reactions in one-third of the patients, and as hemolysis and thrombocytopenia in half of the patients (often with disseminated intravascular coagulation). Currently, chemotherapy is the most effective treatment for outspread gastric cancer. Unfortunately, there is no exclusively effective scheme for treatment. Lymph node metastases are more sensitive to chemotherapy than primary gastric cancer, while in contrary, hepatic metastases are less sensitive than primary gastric cancer. This article includes a literature review and a rare case of gastric cancer.

Sarcoma of the breast is a rare tumor (makes up 0.5 to 1% of all malignant breast tumors). In literature, only isolated cases of primary angiosarcoma of the breast were described. Secondary angiosarcomas are more frequently diagnosed in women and mostly in patients who underwent breast-conserving surgery and were treated by radiotherapy. In this article a very rare case of angiosarcoma of the breast is presented. The tumor in the breast was diagnosed after breast trauma. After surgery the diagnosis of hematoma was made. Nine months after surgery tumor spread was observed in subdermal layer, lymph nodes, and lungs. After review of histopathology slides the likely diagnosis of angiosarcoma of the breast was made. The effect of chemotherapy and radiotherapy was only partial and short. The tumor extended further to the lungs, pleura, and peritoneum. A patient from the time of diagnosis survived for 8 months. The mean survival of patients with angiosarcoma of the breast, described in literature, ranges from 13 to 22 months, and the treatment in this case most likely could not have an effect on survival of the patient.
