Paclitaxel was the first identified member of a new class of anticancer drugs known as the taxanes. This compound has significant single-agent activity against a number of solid tumors including nonsmall cell lung cancer (NSCLC). In the first-line setting, single-agent paclitaxel has been studied on a number of different schedules and dose levels. ⋯ The consistent finding of a 35%-40% one-year survival rate is notable. The major toxicities include neutropenia, neuropathy, and myalgia/arthralgia syndrome. Given the overall activity and impact on survival along with an acceptable toxicity profile, single-agent paclitaxel warrants comparison to other active agents and combination regimens in advanced, metastatic NSCLC.

Although the combination of platinum and paclitaxel offers effective chemotherapy for advanced ovarian cancer, the majority of women will eventually relapse with development of drug-resistant disease. Topotecan is the most extensively studied agent currently available for management of recurrent ovarian cancer and has been approved by the FDA for that particular indication. Early use of topotecan offers an effective and tolerable strategy that can prolong the platinum-free interval and optimize subsequent retreatment with platinum.

The National Cancer Institute (NCI) has recently decided to embark on an international partnership with the developing cancer programs on the Island of Ireland (Northern Ireland and the Republic of Ireland) in an attempt to further improve the quality and range of cancer services available for patients. This Transatlantic Partnership called the All Ireland-NCI Cancer Consortium offers exciting opportunities in cancer treatment, education and research as the cancer-caring communities from both the Republic of Ireland and Northern Ireland prepare to join with the U. S. ⋯ Finally, it is hoped that the Conference will be a marker of a very special interaction on the Island of Ireland focused on the overall development of cancer services for patients. It will also signal the start of an important partnership between the NCI and those involved in cancer care and research in Ireland. This tripartite cooperative agreement is a most exciting venture and it will hopefully be an example of how an effort focused on a human problem common to all societies can generate a spirit of cooperation and help to eliminate strife.

The factors contributing to blood transfusions in patients with anemia of chronic disease are not well documented in the literature. We analyzed all blood transfusion events within a single oncology practice to determine if certain chemotherapy drugs, cancer types, or other factors necessitated more frequent transfusions. ⋯ The results of this study identify transfusion needs associated with certain groups of cancer patients and with certain types of chemotherapy drugs.

Neoadjuvant chemotherapy improves survival in patients with locally advanced breast cancer (LABC). Usually three to four cycles of conventional-dose neoadjuvant chemotherapy are administered prior to local therapy, and another three cycles thereafter. In an attempt to improve results, we increased the dosages and applied GM-CSF, which, besides being a hematopoietic growth factor, has become increasingly known for its immunostimulatory effects, which might enhance the antitumor effect. ⋯ The results of the present study with neoadjuvant dose-intensive AC chemotherapy and GM-CSF compare favorably with previous studies in patients with LABC. This is most apparent in patients who received six cycles of neoadjuvant chemotherapy. We hypothesize that these encouraging results are probably related to the prolonged presence of the primary tumor, and to the long-term administration of GM-CSF with the primary tumor and axillary lymph nodes in situ. Therefore, a randomized study is warranted. We already initiated an international randomized trial in patients with LABC in order to answer two questions. First, does prolonged neoadjuvant chemotherapy result in an improved DFS and OS in comparison with the conventional approach, and secondly, what is the effect of GM-CSF in this approach in comparison with G-CSF?
