Commentary (Pierson): Detection of Nodal Micrometastases in Head and Neck Cancer by Serial Sectioning and ImmunostainingDrs. Ambrosch and Brinck appropriately emphasize the problems and limitations encountered when using routine pathologic procedures to examine lymph nodes from head and neck cancer specimens. Extraordinary processing techniques have repeatedly yielded a larger number of small nodes and, on occasion, have demonstrated the presence of micrometastases. The majority of these observations come from examination of breast specimens and their axillary dissections. Labor-intensive clearing techniques have varied to some extent, but generally involve progressive removal of opaque fat with alcoholic solvents of increasing percentages culminating in absolute alcohol (100%). Final visualization involves submerging the defatted specimen in cedarwood oil, followed by careful examination and dissection of the backlighted specimen.

Measuring the Cost-Effectiveness of Cancer CareHistorically, new therapeutic strategies for cancer have been evaluated on the basis of safety and clinical efficacy. However, the current national emphasis on efficiency of resource allocation has led to the inclusion of economic assessments in oncology studies. Economic assessments measure patients' health status and resource consumption associated with a therapeutic strategy, and combine these in a cost-effectiveness analysis. Study design can include prospective analysis of clinical trials, retrospective analysis of a clinical trial or administrative databases, or a decision analytic model. Economic analysis is being used increasingly in oncology and will continue to provide meaningful data to assist clinicians in determining the optimal treatment strategies for cancer patients and to help inform health policy decision-makers about the importance of specific cancer therapeutic strategies.

Consolidation TherapyWe previously reported the efficacy of concurrent cisplatin (Platinol)/etoposide (PE) and radiotherapy in stage IIIB non–small-cell lung cancer in which biopsy confirmation of T4 (noneffusion) or N3 status was required (S9019). In view of the activity of docetaxel (Taxotere) as second-line therapy and potential molecular mechanisms of action favoring taxane sequencing, we designed the present study to maintain a core of concurrent PE/radiotherapy, but to substitute docetaxel consolidation for the two additional cycles of PE.

The Role of PET-CT Fusion in Head and Neck CancerPositron-emission tomography(PET) and computed tomography(CT) fusion imaging is arapidly evolving technique that is usefulin the staging of non–small-celllung cancer (NSCLC), Hodgkin’s disease,ovarian cancer, gastrointestinalstromal tumors, gynecologic malignancies,colorectal malignancies,and breast cancer. In their article,Rusthoven et al[1] describe the roleof PET-CT in head and neck malignanciesand include a review of allcurrently available literature. Accordingto the authors, PET-CT is usefulfor staging head and neck carcinomasand for target volume delineation duringradiation treatment planning.

Clinical Presentation and Management of Hemolytic AnemiasThe hallmark of hemolysis is shortened red blood cell survival in the peripheral blood. Hemolysis results in anemia only when bone marrow cannot keep up with the rate of red cell destruction. Even though anemia is very commonly observed in most cancer patients, hemolytic anemias are rather rare.

Non-Small-Cell Lung Cancer Adjuvant Therapy: Translating Data Into RealitySurgery remains the initial treatment for patients with early-stage non-small-cell lung cancer (NSCLC). Additional therapy is necessary because of high rates of distant and local disease recurrence after surgical resection. Early trials of adjuvant chemotherapy and postoperative radiation were often plagued by small patient sample size, inadequate surgical staging, and ineffective or antiquated treatment. A 1995 meta-analysis found a nonsignificant reduction in risk of death for postoperative cisplatin-based chemotherapy. Since then, a new generation of randomized phase III trials have been conducted, some of which have reported a benefit for chemotherapy in the adjuvant setting. The role of postoperative radiation therapy remains to be defined. It may not be beneficial in early-stage NSCLC but still may have utility in stage IIIA disease. Improvement in survival outcomes from adjuvant treatment are likely to result from the evaluation of novel agents, identification of tumor markers predictive of disease relapse, and definition of factors that determine sensitivity to therapeutic agents. Some of the molecularly targeted agents such as the angiogenesis and epidermal growth factor receptor inhibitors are being incorporated into clinical trials. Preliminary results with gene-expression profiles and lung cancer proteomics have been promising. These techniques may be used to create prediction models to identify patients at risk for disease relapse. Molecular markers such as ERCC1 may determine response to treatment. All of these innovations will hopefully increase cure rates for lung cancer patients by maximizing the efficacy of adjuvant therapy.

Commentary (Moller): Surgical Staging in Endometrial CancerEndometrial cancer is the mostcommon gynecologic malignancyaffecting women in theUnited States. In 1988, the InternationalFederation of Gynecology andObstetrics shifted from a clinical stagingprotocol to one based on surgicalfactors, making surgical staging theaccepted treatment approach to endometrialcancers, with excellentsurvival compared to other gynecologicmalignancies. The manuscript byKirby et al brings to light the controversiessurrounding the surgical evaluationof endometrial cancers. Althoughsurgical staging has been shown to haveboth prognostic and therapeutic benefit,major problems in the United Statescontinue to result in suboptimal treatmentof patients with endometrial cancer.These problems include the lack ofan accepted surgical protocol (in termsof adequacy of lymph node sampling)and incomplete surgical staging secondaryto patient factors or the lack ofreferral to specialty-trained gynecologiconcologists.

Update on Malignant MesotheliomaMesotheliomas are uncommon in the United States, with an incidenceof about 3,000 new cases per year (or a risk of about 11 per million Americansper year). Incidence and mortality, however, are probably underestimated.Most are associated with asbestos, although some have arisen inports of prior radiation, and a reported association with simian virus (SV)40remains controversial. About 85% of mesotheliomas arise in the pleura,about 9% in the peritoneum, and a small percentage in the pericardiumor tunica vaginalis testis. The histology of about half of mesotheliomas isepithelial (tubular papillary), with the remainder sarcomatous or mixed.Multicystic mesotheliomas and well-differentiated papillary mesotheliomasare associated with long survival in the absence of treatmentand should be excluded from clinical trials intended for the usual rapidlylethal histologic variants of the disease. The median survival isunder a year, although longer median survivals for selected patients,particularly those with epithelial histology, have been reported in somecombined-modality studies. Recent randomized trials have shown significantimprovement in time to progression and survival for the additionof new antifolates to platinum-based chemotherapy.
