Burnout is an important occupational problem for health care workers. We aimed to assess the burnout levels among oncology employees and to evaluate the sociodemographic and occupational factors contributing to burnout levels. The Maslach Burnout Inventory, which is designed to measure the three stages of burnout-emotional exhaustion (EE), depersonalization (DP), and personal accomplishment (PA), was used. ⋯ Furthermore, employees who are not pleased with working in oncology field, who would like to change their specialty if they have an opportunity, and whose family and social lives have been negatively affected by their work experienced higher levels of burnout. Burnout syndrome may influence physical and mental health of the employee and affects the quality of health care as well. Therefore, several individual or organizational efforts should be considered for dealing with burnout.

Comparative Study
c-erbB-2 and the "triple-state" in early breast carcinomas.
Although c-erbB-2 expression is, in general terms, an ominous prognostic indicator in breast carcinomas, there are suggestions that lack of this oncogene, when combined with analogous lack of estrogen (ER negative) and progesterone receptors (PgR negative)-"triple-negative phenotype", is linked with an equally poor prognosis. We investigated this hypothesis in a series of early ductal breast carcinomas. A total of 116 specimens with early breast cancer, defined as tumors of < or =2 cm in size and clinically negative axilla, were studied immunohistochemically for ER, PgR, and c-erbB-2 expression. ⋯ Triple-negative breast carcinomas had a poor prognosis, while triple-positive tumors had a favorable outcome. However, if triple-positive and triple-negative cases were excluded from the original sample, the remaining c-erbB-2 positive cases were connected with poor prognosis, relative to the remaining c-erbB-2 negative tumors. c-erbB-2 oncogene has a complex biological role in early breast carcinomas for its expression characterizes subgroups of patients with both favorable (triple-positive phenotype) and unfavorable prognosis (c-erb-B2 positive cases after excluding triple-positive and triple-negative tumors)-a phenomenon presumably due to activation of different biological pathways. Elucidation of these pathways may determine subgroups of patients with tumors requiring different targeted agents.

Case Reports
Multiple organ metastases of Pulmonary Epithelioid Haemangioendothelioma and a review of the literature.
This report describes a case of pulmonary epithelioid haemangioendothelioma presented as multi-organ metastases including lung, liver and bone in a 56-year-old woman with an initial diagnosis made with thoracoscopic wedge biopsy. The diagnosis is confirmed through immunohistochemistry. ⋯ The rarity of this condition, the lack of clear standards for treatment, and the partial-to-complete spontaneous regression of EHE seen in some patients up to 15 years from initial detection makes it difficult to decide on the most appropriate treatment. This report may contribute to the data on clinical findings and natural history of this rare tumor.

To investigate the possible correlation between expression of HER2 and vascular endothelial growth factor (VEGF), and to determine the predictive value of these factors in patients receiving adjuvant endocrine therapy including the group with a breast cancer (BC) positive for both oestrogen receptor (ER) and progesterone receptor (PgR). ⋯ The results from this retrospective analysis suggest that overexpression of HER2 and higher VEGF expression may add information on patient's outcome after adjuvant endocrine therapy in ER and PgR positive BC.

Bevacizumab, a monoclonal antibody against vascular endothelial growth factor, has shown clinical activity in metastatic colorectal cancer patients when used as either a first-line or second-line treatment. Here, we evaluated the efficacy and safety of bevacizumab plus FOLFIRI (irinotecan, 5-fluorouracil, and leucovorin) or FOLFOX (oxaliplatin, 5-fluorouracil, and leucovorin) in metastatic colorectal cancer cases after failure to FOLFIRI and FOLFOX. Between October 2004 and February 2007, the data on 42 patients with metastatic colorectal cancer after failure of FOLFIRI and FOLFOX were reviewed retrospectively. ⋯ The frequencies of adverse events related BV, such as bleeding, thrombosis, and gastrointestinal perforation, were within the ranges of previous reports. However, there were no treatment-related deaths. The combination of bevacizumab plus FOLFIRI or FOLFOX showed modest activity and was relatively tolerable in patients with metastatic colorectal cancer refractory to both FOLFIRI and FOLFOX.
