RESUMO
BACKGROUND: Survival after high-dose chemotherapy (HDCT) as second-salvage treatment (SST) in multiple relapsed germ-cell tumors (GCTs). PATIENTS AND METHODS: Existing databases in Berlin and Marburg of HDCT trials from 1989 to 2008 were retrospectively screened. Among 534 patients, 71 of 534 (13%) patients were scheduled for HDCT having failed previous conventional-dose first-line and first-salvage chemotherapy regimens; those 49 patients who had received at least cisplatin plus etoposide first-line as well as conventional-dose cisplatin-based first-salvage regimens and were diagnosed after 1 January 1990 were further analyzed. RESULTS: Median age at SST was 32 years (range 19-52 years). Median follow-up for surviving patients was 4 years (range 1.7-8.5 years). Three of 49 (6%) patients either progressed or died before scheduled HDCT; the remaining 46 of 49 (94%) received either single or sequential HDCT. The rate of favorable responses to HDCT was 27 of 49 (55%). Nine patients remain alive and free of progression. One additional patient was lost to follow without progression at 4 years. The projected overall survival rate at 5 years was 17% (95% confidence intervals 7% to 30%). CONCLUSION: HDCT can induce remissions in patients with multiple relapsed GCTs with a long-term survival rate of approximately 17%.

PURPOSE: Intraorbital metastases of solid tumors are a rarely diagnosed clinical condition, even though pathological reports suggest an incidence of up to 30% in cancer patients. We report two cases of intraorbital, extraocular metastases in breast cancer. The first patient was a 45-year-old man who presented with diplopia, upward divergence of the left bulb, and local pain. METHODS: In the standard cerebral magnetic resonance imaging (MRI) no cerebral or ocular tumor was detectable. A subsequent T1-weighted, contrast-enhanced orbital MRI with fat suppression revealed an infrabulbar mass of 18 x 13 mm in size. The second patient, a 59-year-old woman, complained of slight diplopia when looking to the left. Cerebral MRI with fat suppression showed a retrobulbar mass with 17x13 mm. In both patients metastatic breast cancer was known for several years, and both had been in a stable disease situation. Both patients were treated with stereotactic radiation, applying a cumulative dose of 35 and 45 Gy, respectively, which resulted in marked improvement of local symptoms. Most eye metastases of breast cancer are located in the choroidea, while an extrabulbar localization within the orbit is rare, with only 3-10% of all ocular metastases. Autopsy reports reveal that an estimated 10-30% of breast cancer patients develop this form of metastasis. This is in strong contrast to rare clinical case reports, suggesting frequently absent to mild clinical signs and difficult diagnosis. CONCLUSION: If breast cancer patients complain of ophthalmological symptoms such as local pain, impaired vision, or diplopia, it is important to consider ocular or orbital metastatic disease.

BACKGROUND: Combinations of anthracyclines, taxanes and gemcitabine have shown high activity in breast cancer. This trial was designed to evaluate a modified combination regimen as primary chemotherapy. Non-pegylated liposomal doxorubicin (NPLD) was used instead of conventional doxorubicin to improve cardiac safety. Gemcitabine was given 72 h after NPLD and docetaxel as a prolonged infusion over 4 h in order to optimize synergistic effects and accumulation of active metabolites. PATIENTS AND METHODS: Forty-four patients with histologically confirmed stage II or III breast cancer were treated with NPLD (60 mg/m(2)) and docetaxel (75 mg/m(2)) on day 1 and gemcitabine as 4-h infusion (350 mg/m(2)) on day 4. Treatment was repeated every 3 weeks for a maximum of six cycles. All patients received prophylactically recombinant granulocyte colony-stimulating factor. Patients with axillary lymph node involvement after primary chemotherapy received adjuvant treatment with cyclophosphamide, methotrexate and fluorouracil. RESULTS: The clinical response rate was 80%, and complete remissions of the primary tumor occurred in 10 patients (25%). Breast conservation surgery was performed in 19 out of 20 patients (95%) with an initial tumor size of less than 3 cm and in 14 patients (70%) with a tumor size Assuntos

RESUMO
BACKGROUND: For monitoring of arterial blood pressure (ABP) during whole body hyperthermia (WBH) different methods have been recommended. This investigation was performed to evaluate the agreement of invasive measurements at various sites, and to compare invasive and non-invasive methods of ABP monitoring under conditions of a heat-induced extreme vasodilation. METHODS: In 19 patients, 48 treatments with WBH were performed. Measurements of ABP in the radial and femoral artery by oscillometry and by sphygmomanometry were taken at four temperature levels during WBH (37, 40, 41.8 and 39 degrees C). RESULTS: Significant differences were observed between invasive and non-invasive methods for systolic ABP, with higher values for non-invasive measurements. When compared with both invasive measurements for diastolic blood pressures, sphygmomanometry gave higher values and oscillometry gave lower values. Sphygmomanometry also showed higher values for mean ABP compared with all other techniques, while measurements in radial and femoral artery and by oscillometry only differed by approximately 5 mmHg. CONCLUSION: The mean arterial pressure and not the systolic and/or diastolic pressure should guide hemodynamic management during WBH. The sphygmomanometric technique is not recommended for use during hyperthermia.
