Three new aromatase inhibitors have recently completed phase III evaluation as treatment of metastatic breast cancer in post-menopausal women whose disease has progressed despite tamoxifen therapy: anastrozole (ARIMIDEX, Zeneca), letrozole (FEMARA, Novartis) and vorozole (RIVIZOR, Janssen). All belong to the third generation of non-steroidal aromatase inhibitors, and each is superior to previous generations in terms of potency and selectivity. The trials that have been performed compare each agent to megestrol acetate, and letrozole and vorozole to aminoglutethimide. ⋯ In 1999, tamoxifen remains the first choice in the hormonal therapy of breast cancer. Following tamoxifen failure, the optimal second-line hormonal therapy remains undefined, but aminoglutethimide and megestrol acetate are no longer optimal therapy in this setting. The third-generation non-steroidal aromatase inhibitors must now be compared to each other, to the steroidal aromatase inhibitors, to the pure anti-oestrogens, and to tamoxifen.

Lung cancer represents the leading cause of cancer mortality. Non-small cell lung cancer (NSCLC) accounts for about 75% to 80% of lung cancer cases and carries a 5-year survival of about 10% to 15% for all stages. Approximately one third of NSCLC patients present with stage III disease, which is defined as locally advanced tumour confined to the chest without distant metastasis. ⋯ These recent reports of randomised clinical trials of combined modality therapy for stage III NSCLC form the basis for this report. Several new agents, like the taxanes, CPT-II and gemcitabine show promising activity in NSCLC treatment. Ongoing studies are evaluating the potential role of these new agents in combined modality treatment but since the phase III trials have not been reported yet these studies will not be discussed.

Quality of life is receiving increasing attention as a criterion for the assessment of treatment, not least for surgery, in pancreatic cancer. In exocrine pancreatic cancer there are three main symptoms that must be dealt with: pain, loss of weight and jaundice. All of them seriously impair quality of life, but most often pain is the most feared by the patients. ⋯ With this approach the sympathetic fibers lead by the symphathetic chain and further by the nervus splanchnicus major, minor and minors are divided. The denervation is easily done and can be performed bilateraly in one seance. This method will probably be used more often as the technique is now well described.

Anecdotes are powerful tools that humans use to make decisions. Despite their power and influence, they are sometimes misused, and sometimes undervalued. ⋯ Anecdotal information should not be considered as a replacement for, but as a complement to formal research evidence. If evidence-based health care is to meet its potential, the important role of anecdotes must be acknowledged, studied and utilized.
