Performing Economic Evaluations Alongside of Cancer Clinical TrialsHealth care providers and financing organizations have become more aware of the resource constraints on the provision of medical services, thus increasing the importance of economic evaluations within the health care industry.[1,2] This has carried over to the evaluation of new, therapeutic strategies for cancer, which have traditionally been evaluated exclusively for safety and clinical efficacy.

High-Intensity Focused Ultrasound: A Canadian PerspectiveThe use of high-intensity focused ultrasound (HIFU) as a method for ablation of a localized tumor growth is not new. Several attempts have been made to apply the principles of HIFU to the treatment of pelvic, brain, and gastrointestinal tumors. However, only in the past decade has our understanding of the basic principles of HIFU allowed us to further exploit its application as a radical and truly noninvasive, intent-to-treat, ablative method for treating organ-confined prostate cancer. Prostate cancer remains an elusive disease, with many questions surrounding its natural history and the selection of appropriate patients for treatment yet to be answered. HIFU may play a crucial role in our search for an efficacious and safe primary treatment for localized prostate cancer. Its noninvasive and unlimited repeatability potential is appealing and unique; however, long-term results from controlled studies are needed before we embrace this new technology. Furthermore, a better understanding of HIFU's clinical limitations is vital before this treatment modality can be recommended to patients who are not involved in well-designed clinical studies. This review summarizes current knowledge about the basic principles of HIFU and its reported efficacy and morbidity in clinical series published since 2000.

HE4-Another Marker for Gynecologic Cancers: Do We Really Need One?The data on HE4 as a prognosticator in both ovarian and endometrial cancer constitute, at most, an interesting observation, but most likely they are simply a reflection of total tumor burden. There are certainly not enough data to justify making major treatment decisions in ovarian or endometrial cancer on the basis of absolute marker levels. Proteomics and genomics seem more likely to make a difference in this area.

Transplant Registries: Guiding Clinical Decisions and Improving OutcomesAfter nearly 30 years of dedication, the International Bone Marrow Transplant Registry (IBMTR) and the Autologous Blood and Marrow Transplant Registry (ABMTR), by nearly any criterion, can be considered a success. The Registry contains over 120,000 patient records that are an invaluable source of information on both autologous and allogeneic bone marrow transplantations. Through the voluntary efforts of more than 350 institutions, it annually registers over 20% of all transplants occurring in nearly 50 countries and, by some estimates, nearly half of all transplants in North America.

Commentary (Brugge): Endoscopic Ultrasound Fine-Needle Aspiration in the Staging of Non-Small-Cell Lung CancerPrecise mediastinal staging of non-small-cell lung cancer is extremely important, as mediastinal lymph node metastases generally indicate unresectable disease. Reliance on computed tomography (CT) and positron-emission tomography (PET) alone to stage and determine resectability is limited by false-positive results. Whenever possible, pathologic confirmation of metastases is desirable. Mediastinoscopy and transbronchial fine-needle aspiration are widely established but imperfect modalities. Endoscopic ultrasound fine-needle aspiration (EUS-FNA) has emerged as a diagnostic and staging tool because of its safety, accuracy, and patient convenience. We reviewed 13 prospective studies evaluating the comparative performance of EUS for staging lung cancer. We conclude that EUS is a valuable staging modality. Further studies of the role of EUS compared to other modalities such as integrated PET/CT and endobronchial ultrasound (EBUS) are forthcoming.

Distant Effects of Cancer on the Nervous SystemThe first descriptions of neurologic disorders in patients with cancer identified those who had peripheral neuropathy. Most neurologists thought these patients actually had a peripheral neuropathy secondary to the inanition associated with their cancer. Still other patients clearly had peripheral neurologic damage from chemotherapy (eg, vincristine).

Irinotecan and Carboplatin in Metastatic or Recurrent NSCLC: An UpdateThe 1-year survival for patients with metastatic non–small-cell lungcancer is only around 35%. We are evaluating the combination ofirinotecan (Camptosar) and carboplatin (Paraplatin) in patients withstage IIIB and IV non–small-cell lung cancer. The first five patientsreceived irinotecan, 250 mg/m2 over 90 minutes followed by carboplatinat an area under the concentration-time curve of 5 over 1 hour. Thedose of irinotecan was subsequently reduced to 200 mg/m2 in view offebrile neutropenia in one of five patients. Chemotherapy cycles arerepeated every 21 days. Patients are reevaluated every two cycles. Of aplanned 42 patients, 37 have been enrolled so far. Of the 37 enrolledpatients, 25 received at least two cycles, 20 received at least four cycles,and 12 received all six planned cycles. Grade 4 neutropenia (absoluteneutrophil count < 500) occurred in 10 patients and 19 treatment cycles.Two of these patients also had grade 4 diarrhea. Thirty-six cycles (30%)were delayed for neutropenia, six of which occurred among the firstfive patients who received irinotecan at 250 mg/m2. Best response totherapy included 7 partial responses (23%), 11 stable disease (37%),with 12 patients having progressive disease (40%). The regimen ofirinotecan and carboplatin administered once every 3 weeks is tolerableand convenient, with early evidence of activity. The main toxicityis hematologic. This study is ongoing and actively accruing patients.

Discovery, Development, and Clinical Applications of BortezomibProteasome inhibition is a novel, targeted approach in cancertherapy. Both natural and synthetic proteasome inhibitors selectivelypenetrate cancer cells, disrupting the orderly destruction of key regulatoryproteins involved in tumorigenesis and metastasis. Disrupting theorderly destruction of regulatory proteins causes an imbalance of theseproteins within the cell, which interferes with the systematic activationof signaling pathways required to maintain tumor cell growth and survival;therefore, cellular replication is inhibited and apoptosis ensues.

Commentary (Sause): Evaluation and Definitive Management of Medically Inoperable Early Stage Non-Small-Cell Lung CancerLung cancer is estimated to be the second most commonly diagnosed cancer in both men and women in 2006, and the leading cause of cancer mortality. Non-small-cell lung cancer represents the majority of such cases. Most of these patients have locally advanced disease at presentation and are not eligible for curative resection. For the minority of patients who are technically resectable at presentation, lobectomy or pneumonectomy and pathologic mediastinal nodal staging offer the best overall survival. The high rate of comorbid medical illness and poor baseline pulmonary function in this population, however, make many such early-stage patients medically inoperable. For these patients, conventional single-modality radiotherapy has been the primary definitive treatment option, as discussed in part 1 of this article, which appeared in last month's issue. Numerous retrospective reports demonstrate long-term disease-free and overall survival data that are modestly superior to that expected after observation, but both local and distant failure continue to be significant risks. Investigation of radiotherapy dose escalation is ongoing, in an effort to improve local control while maintaining minimal toxicity. Additionally, emerging evidence suggests that new modalities, such as stereotactic radiosurgery and radiofrequency ablation, may also be potentially curative treatment alternatives. These modalities are addressed in part 2.
