Phase II Study of Docetaxel and Irinotecan in Metastatic or Recurrent Esophageal Cancer: A Preliminary ReportThe outcomes for patients with metastatic or recurrent esophagealcancer are dismal, with 1-year survival rates of approximately 20%. Inthis phase II study, we studied the combination of docetaxel (Taxotere)and irinotecan (CPT-11, Camptosar) in patients with metastatic orrecurrent esophageal cancer. Eligible patients included those withhistologic or cytologic diagnosis of adenocarcinoma or squamouscancer of the esophagus or gastroesophageal junction who had receivedno previous chemotherapy for metastatic esophageal cancer. Previouschemotherapy in the neoadjuvant or adjuvant setting was allowed.Patients received irinotecan at 160 mg/m2 over 90 minutes followed bydocetaxel at 60 mg/m2 intravenously over 1 hour, with chemotherapycycles repeated every 21 days. Patients were reevaluated every twocycles. Of a planned 40 patients, 15 were enrolled, with 14 patientsevaluable for toxicity and 10 evaluable for response and survival. Thecombination of docetaxel and irinotecan resulted in a response rate of30%. An additional 40% achieved stable disease. The median survivalwas 130 days, with three patients still alive at the time of this analysis.The toxicities included 71% incidence of grade 4 hematologic toxicities,with 43% febrile neutropenia. One patient died of cecal perforationafter one cycle. There was no evidence of pharmacokinetic interaction,as systemic clearance of both drugs was similar to that seen after singleagentadministration. In conclusion, the regimen of docetaxel andirinotecan is active in metastatic or recurrent esophageal cancer.However, this combination chemotherapy regimen has an unacceptablerate of febrile neutropenia. This regimen needs to be modified toreduce the incidence of febrile neutropenia.

An Argument Against Routine Use of Radiotherapy for Ductal Carcinoma In SituThe major conclusion to bedrawn from the extensivelypublished University of SouthernCalifornia (USC)/Van Nuys databaseon ductal carcinoma in situ(DCIS) is that, to the extent that DCIScan be totally excised, the ipsilaterallocal control rate will approach 100%with surgery alone, regardless of tumorgrade or size or patient age. Thisconclusion, noted by Dr. Silverstein,was achieved only through prospectivemammographic/pathologic correlationand a meticulous pathology protocolthat required orientation, selectiveinking of margins, sequential sectioningand processing of the entirespecimen, and prospective calculationof size and margin status.

Reviving the Acid Phosphatase Test for Prostate CancerProstatic acid phosphatase (PAP) emerged as the world's first clinically useful tumor marker in the 1940s and 1950s. With the introduction of the prostate-specific antigen (PSA) test in the 1980s, which performed significantly better than PAP in terms of screening and monitoring response to treatment, PAP fell into disfavor. An increasing number of recent studies have identified PAP as a significant prognostic factor for patients with intermediate- and high-risk prostate cancer. PAP appears to be particularly valuable in predicting distant failure in higher-risk patients for whom high levels of local control are achieved with aggressive initial local treatment. As prostate cancer care becomes increasingly focused on identifying the minority of patients who would benefit from aggressive systemic therapy, a reevaluation of the potential contribution of the prostatic acid phosphatase test seems timely.

Getting a Handle on Posttransplant Recurrence of HCCIn this issue of ONCOLOGY, Kim et al discuss adjuvant therapy after liver transplantation to decrease recurrence of hepatocellular carcinoma (HCC). Liver transplantation offers the best overall and recurrence-free survival for the treatment of stage I and II HCC. The landmark study in 1996 by Mazzaferro demonstrated that liver transplantation of patients with one lesion less than 5 cm or with up to three lesions but all less than 3 cm (the Milan criteria) resulted in low recurrence rates and similar survival to patients without HCC.[1]

Emotional and Behavioral Responses to Genetic Testing for Susceptibility to CancerDrs. Lerman and Croyle provide a quite thorough review of an area in need of continuing research-ie, patients' behavioral and emotional responses to genetic testing for cancer susceptibility. The authors present current information on what we do and don't know about the psychological characteristics of individuals likely to undergo testing, possible adverse reactions, issues specific to the genetic counseling process, family coping and adaptation, and possible ways of managing psychological sequelae of genetic testing. Admirably, the authors note that much of their discussion should be considered speculative until more empirical data specific to genetic testing is available. Given this "state of the science," I will raise some additional questions based on some of the statements made by Drs. Lerman and Croyle.

Commentary (Sarosdy): Age-Specific Reference Ranges for PSA in the Detection of Prostate CancerDr. DeAntoni provides a timely, critical review of the concept of age-specific prostate-specific antigen (PSA) ranges, as well as other frequently used attempts to improve the accuracy of serum PSA testing in the diagnosis of unsuspected prostate cancer. His review is complete, and his assessments of each of the modalities reflect not only the majority view but also realistic appraisals of the limitations of this less-than-perfect test.

Commentary (Herman/Wharam): Current Techniques in Three-Dimensional CT Simulation and Radiation Treatment PlanningStephenson and Wiley demonstrate that three-dimensional (3D) CT-based simulation is an improvement in the simulation process. The growing importance of CT in radiation oncology treatment planning has been discussed previously [1] and is further emphasized in this article. The advantages of geometric optimization in three dimensions for radiation therapy treatment planning also are described. These results are applicable to both 3D and two-dimensional (2D) dose planning, because the treatment team can visualize and delineate structures on axial or reconstructed CT planes in greater detail than is possible with conventional simulation projected radiographs.

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.
