Disparities in Cancer Care Among Racial and Ethnic MinoritiesEliminating cancer disparities-not only for racial/minority groups but for all underserved populations-must be a priority for those involved in cancer care. For individual practitioners, the first step in addressing disparities is accomplished through understanding the possibility that disparities exist in varying depth and complexity for each racial or ethnic minority patient.

The Evolving Paradigm of Adult Cancer Survivor CareCurrent US statistics on cancer reveal that more than 11 million cancer survivors live among us today, and that number is expected to double by 2050.[1,2] One important contributing trend has been a fall in cancer deaths driven by earlier detection and improved treatment. Deaths resulting from cancer declined from 206.7 per 100,000 population in 1980 to 185.7 per 100,000 in 2004. Meanwhile, the adjusted 5-year survival rate for cancers overall increased from 50% to 66% between 1975–1977 and 1996–2003,[3] and these statistics speak only to relatively short-term survival. About 1 in every 7 survivors today received their diagnosis more than 20 years ago.[4]

Identifying Predictive and Surrogate Markers of Erlotinib Antitumor Activity Other Than RashThe identification of predictive or surrogate markers of response toHER1/epidermal growth factor receptor (EGFR) inhibitor treatmentwould permit selection of patients most likely to respond to such treatment.Markers could consist of tumor characteristics (eg, characteristicsof the receptor or downstream signaling molecules and determinantsof resistance) or host characteristics (eg, pharmacokinetic parametersand toxicities). The occurrence of rash may constitute a surrogatemarker of response to erlotinib (Tarceva) treatment in patientswith non–small-cell lung cancer and other cancers. The erlotinib markeridentification program has been designed to identify and investigateother candidate markers by analysis of a large number of clinicalsamples from patients enrolled in erlotinib trials in non–small-cell lungcancer, including the phase III TALENT and TRIBUTE trials oferlotinib combined with chemotherapy and the phase III BR.21 trial oferlotinib monotherapy in advanced non–small-cell lung cancer. Thisprogram should both contribute to understanding of the molecular biologyof HER1/EGFR inhibition and result in identification of potentialmarkers that can be evaluated in the clinical setting.

Medulloblastoma: Molecular Classifications and Prognostic AssociationsOf particular relevance for clinicians is the possible recommendation of omitting concurrent chemotherapy with CSI in adults, due to the lower marrow reserves and overall lack of data for clear efficacy of concurrent chemotherapy in adults. Additional refinement of these therapeutic regimens for adult medulloblastoma awaits further advances in both the molecular prognostic associations for these tumors and the potentially exciting development of targeted therapies for specific molecular subtypes.

Management of Carcinoma of the Superior Pulmonary SulcusTumors of the superior pulmonary sulcus (Pancoast tumors) are bronchogenic carcinomas that occur at the thoracic inlet and typically involve, by direct extension, the lower trunks of the brachial plexus, the intercostal nerves, the stellate ganglion, and adjacent ribs and vertebrae. These tumors are rare, comprising 5% of all lung cancers. Treatment of Pancoast tumors has traditionally consisted of preoperative radiation to a dose of 3,000 to 4,500 cGy followed by surgical resection. Overall 5-year survival rates range from 30% to 50%. Even if treatment achieves local disease control, distant failure (brain or bone) is common. Recent treatment efforts have focused on the use of induction chemoradiation followed by surgery and further chemotherapy. This combined-modality approach may become the new treatment paradigm for Pancoast tumors. [ONCOLOGY 11(6):781-785, 1997]

Overview of Prognostic Factors in Non-Hodgkin’s LymphomaThe non-Hodgkin’s lymphomas are a biologically heterogeneous group of diseases with varying clinical presentations and outcomes. A number of studies have identified variables that carried independent prognostic significance. Although several staging systems had evolved that incorporated these prognostic variables, they were still unable to predict outcome. Ideally, the object of a staging system is to predict the likelihood of treatment response, time to progression or disease-free survival, and overall survival, and to provide a way to compare the outcome of similar groups of patients among various clinical trials. The need for such a system led to the creation of prognostic models such as the M. D. Anderson Tumor Score and, more recently, the International Prognostic Index. These prognostic models may identify those patients at highest risk for treatment failure, thereby identifying those patients who may require different therapeutic approaches.

Current Status of Genetic Testing for Colorectal Cancer SusceptibilitySolomon et al have written a valuable primer to guide clinicians in identifying, diagnosing, and treating familial colon cancer syndromes. The authors succinctly describe the essential features of each of the well-defined hereditary colon cancer syndromes, including those associated with colonic adenomas (hereditary nonpolyposis colorectal cancer [HNPCC] and familial adenomatous polyposis [FAP]) and colonic hamartomas (Peutz-Jeghers syndrome, juvenile polyposis, and Cowden syndrome). In addition to the specific features that might trigger recognition of one of these syndromes, we advise health-care providers to consider the possibility of hereditary cancer in cases with the following features:
