Neoadjuvant endocrine treatment in which therapy is given while the primary tumour is still in the breast provides a highly useful model system by which to identify mechanisms associated with de novo resistance and signs of early acquired resistance. Most importantly, the model is clinically relevant. It has been confirmed that the absence of tumour oestrogen receptors confers resistance to end...

Systemic therapy for breast cancer is evolving rapidly. The medical treatment of cancer includes chemotherapy, endocrine therapy, and therapy with targeted biologic agents. In the past, a patient’s stage, based on tumor size and nodal involvement, would determine the recommendations for medical therapy, whereas now the biologic features of the tumor direct the treatment plan. As a result of adv...

Neoadjuvant radio(chemo)therapy is increasingly used in rectal cancer and induces a number of morphologic changes that affect prognostication after curative surgery, thereby creating new challenges for surgical pathologists, particularly in evaluating morphologic changes and tumour response to preoperative treatment. Surgical pathologists play an important role in determining the many facets of...

Pancreatic cancer is a devastating disease. It is the fourth leading cause of cancer-related death in Germany. The incidence in 2003/2004 was 16 cases per 100.000 inhabitants. Of all carcinomas, pancreatic cancer has the highest mortality rate, with one- and five-year survival rates of 25% and less than 5%, respectively, regardless of the stage at diagnosis. These low survival rates demonstrate...

PURPOSE Neoadjuvant therapy is associated with considerable toxicity and limited survival benefits in patients with soft tissue sarcoma (STS). We prospectively evaluated whether 2[18F]fluoro-2-deoxy-d-glucose ((18)F-FDG)-PET/computed tomographic (CT) imaging after the initial cycle of neoadjuvant therapy could predict overall survival in these patients. EXPERIMENTAL DESIGN Thirty-nine patient...

In HER2-positive early breast cancer, neoadjuvant treatment with a combination of sequential chemotherapy and HER2-targeted therapy is currently the standard of care. This is followed by breast surgery, radiotherapy (if indicated), completion of 12 months of HER2-directed therapy, and - depending on the tumor biology - endocrine adjuvant therapy, and ultimately follow up. 10-year survival rates...

Primary systemic therapy (PST) or neoadjuvant therapy is used in nonmetastatic breast cancer to treat systemic disease earlier, decrease tumor bulk ideally to a complete pathological response (pCR), and reduce the extent of surgery. The multitude of clinical trials using PST in breast cancer patients has not proven the fundamental hypotheses of improved overall survival and disease-free surviva...

The demonstration of the activity of capecitabine (Xeloda) in advanced breast cancer and of the ability of capecitabine/docetaxel (Taxotere) to improve tumor response, time to disease progression, and survival in this setting has prompted considerable interest in examining uses of capecitabine in adjuvant and neoadjuvant therapy. Trials are planned to compare capecitabine/docetaxel with docetax...

Neoadjuvant therapy is an under-utilized regimen for the treatment of metastatic melanoma. The use of this approach has been increasing in other tumor types. Neoadjuvant therapy may reduce occult circulating tumor cell burden in the face of bulky disease and afford a real time evaluation of treatment effectiveness. Neoadjuvant approach can also provide preoperative histologic and molecular anal...

Background Neoadjuvant chemotherapy is administered to control disease, make surgical resection possible and increase the possibility of breast tissue conservation. A further advantage of neoadjuvant therapy is that it helps to assess chemo-sensitivity to a particular agent. Induction of a pathological complete response (pCR) is one of the primary goals of neoadjuvant therapy in order to achiev...
