ReviewEmerging pathways in the development of chondrosarcoma of bone and implications for targeted treatment.
Chondrosarcoma is a malignant cartilage-forming tumour of bone, of which distinct clinicopathological subtypes are known. Conventional chondrosarcoma is notorious for its locally aggressive behaviour as well as for its resistance to chemotherapy and radiotherapy; so far surgery is the only effective therapeutic option. During the past 10 years, substantial new insights have been gained about molecular cell biology, molecular cytogenetics, and immunopathology, leading to better understanding of chondrosarcoma development at the molecular level, which will ultimately lead to better clinical understanding and possibly to the development of targeted treatment.

Review Comparative StudySystematic review of taxane-containing versus non-taxane-containing regimens for adjuvant and neoadjuvant treatment of early breast cancer.
The use of taxanes in early breast cancer is increasing. However, there are few mature studies of taxanes in this setting, and their role is uncertain. Our systematic review of randomised trials of adjuvant or neoadjuvant systemic therapy identified ten reported trials comparing a taxane-containing group with a non-taxane-containing control group in women with early breast cancer. ⋯ Two trials showed a significant improvement in overall survival. These results support the use of adjuvant taxanes in women with early breast cancer and involved lymph nodes. Longer follow-up of these trials and results from continuing trials are needed to clarify the best use of taxanes in early breast cancer.

Review Historical ArticleOestrogen receptor beta: what it means for patients with breast cancer.
Oestrogen receptor (ER) alpha is a well established prognostic marker in breast cancer, and all patients who are ER alpha positive receive tamoxifen as adjuvant endocrine therapy. Although ER alpha predicts a favourable disease outcome, the usefulness of ER beta as a clinical prognostic marker remains to be defined. Here, we outline the history of both ERs and discuss the implications ER beta has to patients with breast cancer.

ReviewRole of imbalance between neutrophil elastase and alpha 1-antitrypsin in cancer development and progression.
Neutrophil elastase and alpha 1-antitrypsin are a pair of protease and protease inhibitor counterparts. The imbalance between the two counterparts is generally thought to cause tissue damage, which could create a favourable tissue environment for carcinogens and tumour progression. ⋯ Several mechanisms of carcinogenesis have been postulated. Excess neutrophil elastase might facilitate cancer development by causing tissue damage and air trapping, which foster longer carcinogen exposure, might promote cancer progression by degrading the intercellular matrix barrier, and might directly lead to cancer development through the tumour-necrosis-factor signalling pathway.

By use of modern immunological and molecular analytical techniques, cells with the characteristics of tumour cells can be detected in the blood of many patients with breast cancer. The ability to detect and characterise such cells routinely could have a profound influence on the early diagnosis of breast cancer, risk stratification in the adjuvant setting, early detection of relapse, and the development of new targeted strategies. In this review we discuss current techniques to detect circulating breast-cancer cells and the limitations of these approaches. We also review the clinical studies in breast cancer and discuss the potential relevance of this research to the future management of the disorder.
