First-Cycle CSF Use in Breast Cancer and NHL: Guidelines and RecommendationsGrade 3 and 4 neutropenia as well as febrile neutropenia have been demonstrated to occur in all tumor types and are clearly associated with major morbidity and significant mortality; this is particularly true when myelosuppressive regimens are used with curative intent as is the case in most breast cancer and non-Hodgkin's lymphoma regimens. Myeloid colony-stimulating factors (CSFs) substantially decrease the risk of severe and febrile neutropenia. Although the white cell growth factors might not be cost-effective at lower risks of febrile neutropenia, they clearly benefit other outcomes such as the incidence of severe neutropenia and febrile neutropenia, hospitalization, and mortality. Updated guidelines from the American Society of Clinical Oncology, the National Comprehensive Cancer Network, and the European Organisation for Research and Treatment of Cancer now recommend primary prophylaxis or first-cycle use of white cell growth factors with regimens where the occurrence of febrile neutropenia is approximately 20% (as well as when other risk factors are present). This article briefly describes the rationale for the development of several of the guideline changes as well as highlights some of the ongoing issues related to the use of CSFs.

Commentary (Berenson/Yeh): Osteonecrosis of the Jaw in Cancer Patients Receiving IV BisphosphonatesCases of osteonecrosis of the jaw (ONJ) have been reported with an increasing frequency over the past few years. ONJ is most often identified in patients with cancer who are receiving intravenous bisphosphonate therapy but it has also been diagnosed in patients receiving oral bisphosphonates for nonmalignant conditions. The condition involves exposed bone of the maxilla or mandible. Although it is often associated with a recent dental surgical procedure, spontaneous ONJ can also occur. Patients commonly present with symptoms. Through case reporting and clinical experience, there is a suggestion that the incidence of ONJ in patients with cancer receiving intravenous bisphosphonates ranges between 1% and 10%. Management of ONJ focuses on maximizing oral health, conservative actions with mouth rinses, antibiotics, and avoidance of unnecessary invasive dental procedures. The currently available data on ONJ are reviewed here.

Gemcitabine and Platinum-Based Chemotherapy in Metastatic Breast CancerAlthough anthracyclines and the taxanes comprise the most activefirst-line cytotoxic treatments in patients with hormone-insensitive orlife-threatening metastatic breast cancer, many patients progress andrequire other chemotherapeutic agents. Development of new combinationsand/or agents is thus needed. Gemcitabine (Gemzar) and platinumcompounds have been employed as single agents, and the additionof gemcitabine to the platinums results in significant clinical benefitand response rates. Correlative biologic studies are expected fromseveral already-reported trials and may help elucidate predictive factorsfor both response and toxicity when combining gemcitabine andthe platinums. Trials incorporating these doublets in earlier stages ofbreast cancer or in the neoadjuvant setting may further elucidate theirrole in breast cancer treatment.

Evolving Role of Stem Cell Transplant in the ElderlyHematopoietic stem cell (HSC) transplantation may improve outcomes of patients with hematologic malignancies not curable with conventional therapies. In some clinical settings, transplantation represents the only curative option. The feasibility and efficacy of this approach in older patients are undefined, since this population has been excluded from nearly all clinical trials. Advances in supportive care, HSC harvesting, and safer conditioning regimens have made this therapy available to patients well into their 6th and 7th decades of life. Recent evidence suggests that elderly patients with good performance status and no comorbidities could, in fact, not only survive the transplant with reasonable risk, but also benefit in the same measure as younger patients.

Reassessments of ESAs for Cancer Treatment in the US and EuropeAnemia is a widely prevalent complication among cancer patients. At the time of diagnosis, 30% to 40% of patients with non-Hodgkin lymphoma or Hodgkin lymphoma and up to 70% of patients with multiple myeloma are anemic; rates are higher among persons with myelodysplastic syndromes. Among patients with solid cancers or lymphomas, up to half develop anemia following chemotherapy. For almost 2 decades, erythropoiesis-stimulating agents (ESAs) were the primary treatment for cancer-related anemia. However, reassessments of benefits and risks of ESAs for cancer-associated anemia have occurred internationally. We reviewed guidelines and notifications from regulatory agencies and manufacturers, reimbursement policies, and utilization for ESAs in the cancer and chronic kidney disease settings within the United States, Europe, and Canada. In 2008 the US Food and Drug Administration (FDA) restricted ESAs from cancer patients seeking cure. Reimbursement is limited to hemoglobin levels < 10 g/dL. In the United States, ESA usage increased 340% between 2001 and 2006, and decreased 60% since 2007. The European Medicines Agency (EMEA) recommended that ESA benefits do not outweigh risks. In Europe between 2001 and 2006, ESA use increased 51%; since 2006, use decreased by 10%. In 2009, Canadian manufacturers recommended usage based on patient preferences. In Canada in 2007, approximately 20% of anemic cancer patients received ESAs, a 20% increase since 2004. In contrast to Europe, where ESA use has increased over time, reassessments of ESA-associated safety concerns in the United States have resulted in marked decrements in ESA use among cancer patients.

Anthracycline and Trastuzumab in Breast Cancer TreatmentThis study was designed to evaluate the cardiac safety of the combined treatment of HER2-positive metastaticbreast cancer patients with trastuzumab (Herceptin) plus epirubicin and cyclophosphamide (EC) incomparison with EC alone in HER2-negative metastatic breast cancer patients. Patients included those withmetastatic breast cancer without any prior anti-HER2 treatment, anthracycline therapy, or any other chemotherapyfor metastatic disease. This was a nonrandomized, prospective, dose-escalating, multicenter, openlabel,phase II study in Germany. A control group of 23 patients received EC 90/600 mg/m2 3-weekly for sixcycles (EC90 alone). A total of 26 HER2-positive patients were treated with trastuzumab, or H (2 mg/kg weeklyafter an initial loading dose of 4 mg/kg), and EC 60/600 mg/m2 3-weekly for six cycles (EC60+H); another 25HER2-positive patients received H and EC 90/600 mg/m2 3-weekly for six cycles. Asymptomatic reductions inleft ventricular ejection fraction (LVEF) of more than 10% points were detected in 12 patients (48%) treatedwith EC60 + H and in 14 patients (56%) treated with EC90 + H vs 6 patients (26%) in the EC90 alone cohort.LVEF decreases to < 50% occurred in one patient in the EC60+H cohort and in two patients in the EC90+Hcohort during the H monotherapy. No cardiac event occurred in the cohort with EC90 alone. The overallresponse rates for EC60+H and EC90+H were >60%, vs 26% for EC90 alone. The interim results of this studysuggest the cardiac safety of the combination of H with EC may be greater than that of H with AC (doxorubicin[Adriamycin]/cyclophosphamide); however, studies in larger numbers of patients are warranted. The combinationregimen revealed promising efficacy.

Hormone-Resistant Prostate Cancer: New Therapies NeededHormone-refractory prostate cancer (HRCaP) is both heterogeneous and lethal. Multiple treatment options exist, including secondary hormonal manipulations, chemotherapy, experimental options, and best supportive care. Choosing the appropriate therapy for an individual patient depends on several important clinical factors such as the presence or absence of symptomatic metastatic disease, age and comorbidities, and prostate-specific antigen velocity. While only docetaxel (Taxotere)-based chemotherapy has been proven to improve survival in this setting, a wide range of therapies may be effective for any individual. Palliative maneuvers, such as external-beam radiation, bisphosphonate therapy, radiopharmaceuticals, and pain management are critical for appropriate patient management. Several promising novel therapies are in late-stage testing and will hopefully provide more treatment options for these patients.
