Neutropenia is the primary dose-limiting toxicity in patients treated with myelosuppressive chemotherapy, leading in some cases to substantial morbidity and early mortality, and disrupting treatment with potentially curative regimens. The use of granulocyte colony-stimulating factors (G-CSFs) such as filgrastim (Neupogen) and pegfilgrastim (Neulasta), as primary prophylaxis starting in the first cycle of chemotherapy, has been shown to reduce the rates of febrile neutropenia (FN) and of FN-related hospitalization, as well as the use of intravenous anti-infectives. A recent meta-analysis has shown significantly lower infection-related mortality with the first-cycle use of G-CSFs. Both filgrastim and pegfilgrastim were originally approved on the basis of their effectiveness in patients treated with chemotherapy regimens that are associated with a 40% or greater risk of FN. Pegfilgrastim, which is given once per cycle, has been shown to reduce the risk of FN by 94% in breast cancer patients treated with docetaxel (Taxotere). In addition, a recent cost-minimization analysis has shown that first-cycle use of pegfilgrastim may be cost-neutral in patients in whom the predicted risk of FN is less than 20%. These findings have important implications for clinical guidelines for preventing chemotherapy-induced neutropenia and FN.

After 2 decades of minimal progress, there have been important advances in the treatment of brain tumors with chemotherapy. A trial conducted by the European Organization for Research and Treatment of Cancer (EORTC) and the National Cancer Institute of Canada (NCIC) recently demonstrated the benefit of radiation therapy with concomitant and adjuvant temozolomide (Temodar) chemotherapy for glioblastomas. There is also increasing evidence that chemotherapy may be beneficial for anaplastic and low-grade gliomas, as well as a variety of less common tumors.

President Bush's request for fiscal year (FY) 2007 contained some unpleasant news for the cancer community, including a small but symbolically significant cut in funding for the National Cancer Institute (NCI).

Officials of the National Cancer Institute have welcomed two new guidance documents issued by the US Food and Drug Administration (FDA). The two aim at making it easier for clinical researchers to conduct small-scale human studies of exploratory drugs prior to phase I trials.

Most thyroid cancers are slow-growing, easily treatable tumors with an excellent prognosis after surgical resection and targeted medical therapy. Unfortunately, 10% to 15% of thyroid cancers exhibit aggressive behavior and do not follow an indolent course. Approximately one-third of patients with differentiated thyroid cancers will have tumor recurrences. Distant metastases are present in about 20% of patients with recurrent cancer.

Men with prostate cancer generally make treatment decisions based on differences in the information they receive rather than their own preferences, according to a new review.

Researchers have found that mammography coupled with magnetic resonance imaging (MRI) is extremely sensitive in the detection of ductal carcinoma in situ (DCIS).

ImClone Systems Incorporated and Bristol-Myers Squibb Company recently announced that the US Food and Drug Administration (FDA) has approved cetuximab (Erbitux), an immunoglobulin (Ig)G1 monoclonal antibody, for use in the treatment of squamous cell carcinoma of the head and neck.

In today's regulatory review environment, how do we keep the patient at center stage?

Socioeconomic factors predominantly explain racial and ethnic disparities in prostate cancer outcomes, according to a new study.

The American Journal of Nursing (AJN) recently released a consensus report based on the outcome of the invitational symposium, "The State of the Science on Nursing Approaches to Managing Late and Long-Term Sequelae of Cancer and Cancer Treatment," which took place in Philadelphia in July 2005. The report, which accompanied the March issue of AJN, offers action strategies and recommendations, from a nursing perspective, for addressing the health needs of the more than 10 million long-term cancer survivors alive today.

A 46-year-old multiparous (gravida 3, para 3) woman presented to her primary care provider with a palpable vulvar polypoidal mass, measuring 7 cm in greatest dimension. The mass was painless and had been growing in size over the past 2 years. Her medical history was remarkable for obesity, hypothyroidism, and an appendectomy at age 17. Her family history was significant for a sister with breast cancer, diagnosed at age 34. A core biopsy was performed.

Over the past 2 decades, we have seen major progress in the management of women with ovarian cancer, with improvements in both overall survival and quality of life. To truly appreciate this progress, it is important to understand the state of affairs regarding the treatment of ovarian cancer in the early 1980s. This paper will discuss that historical background, describe the increasingly favorable impact of evolving treatment paradigms in ovarian cancer, and note future directions for clinical research in this complex disease process.

Elderly patients with stage I-III non-small-cell lung cancer (NSCLC) constitute a peculiar patient population and need specific therapeutic approaches. Limited resections are an attractive alternative for elderly patients with resectable NSCLC because of the potential reduction in postoperative complications. Curative radiation therapy is an acceptable alternative for elderly patients who are unfit for or refuse surgery. Hypofractionated stereotactic body radiation therapy is of particular interest for this population because of its favorable tolerance.

In part 2, we address risk assessment and staging, findings that suggest the presence of aggressive tumors, recurrent/metastatic disease, and treatment with chemotherapy and external-beam radiotherapy. Experimental treatments utilizing molecular targets, redifferentiation agents, and gene therapy are covered briefly as well.
