Solomon 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:
Cytoreductive Surgery Is the Best Way to Affect Survival Outcomes
Outcome is described for 1,034 children who received radiation treatment in the management of a brain tumor at the University of Toronto Institutions from 1958 to 1995. The 5-, 10-, 20-, and 30-year relapse-free (or
Dr. Fakih and colleagues provide a detailed and thoughtful review of the role of chemoradiation in anal cancer treatment. They have included a comprehensive description of the epidemiology and risk factors for the development of squamous cell carcinoma of the anal canal, including the strong association with human papillomavirus (HPV) infection and increased incidence in human immunodeficiency virus (HIV)-positive individuals.
In most cases, localized small-cell bladder cancer requires cystectomy for optimal cure rates.
Stage IB non–small-cell lung carcinoma (NSCLC) represents a subset of early-stage, resectable NSCLC, usually treated with curative intent, but with historically modest 5-year survival rates ranging from 40% to 67% with surgical resection alone.[1,2] Disappointingly, modern adjuvant chemotherapy trials including stage IB patients have shown little evidence of chemotherapeutic benefit.
The development of effective and well-tolerated combinations of chemotherapy and radiotherapy is of great importance to improve disease-free survival in patients treated for non–small-cell lung cancer. Studies
Paclitaxel (Taxol) has aroused considerable interest for its high single-agent activity in breast cancer and novel mechanism of action. Epirubicin (Farmorubicin), the 4'epimer of doxorubicin (Adriamycin), also has high activity in
The body of research addressing the palliative care−oncology collaboration continues to accumulate; however, sustained efforts are needed to ensure that we are providing the best possible care for our patients.
Parsons and colleagues present an excellent summary of their clinical experience with ocular complications of radiotherapy for primary periocular malignancies, together with a retrospective review of the literature on this subject. The authors emphasize the roles of both total dose and dose-per-fraction in radiation-associated eye complications.
As genome-wide association studies (GWAS) have opened the door to systematic discovery of genetic factors for complex diseases, including cancers, the clinical utility of the findings remains to be determined. This is elegantly discussed in the article in this issue of ONCOLOGY by Stadler et al. The authors rightfully caution against the use of “personal genomic tests” based on cancer GWAS results for personal cancer risk prediction.
Cetuximab (Erbitux), a chimeric antiepidermal growth factor receptor monoclonal antibody currently used to treat metastatic colorectal cancer, is in clinical development for several other solid tumors. Although cutaneous manifestations are the most common toxicities associated with cetuximab, they are rarely life-threatening. Cetuximab-related infusion reactions are less common, but they may become severe and cause fatal outcomes if not managed appropriately. Little about the specific etiology of these events is known; however, an overview of infusion reactions observed with other compounds may shed some light and help characterize cetuximab-related reactions. For physicians administering cetuximab, familiarity with acute reaction treatment protocols and preparedness to identify and manage symptoms promptly and effectively are most important to minimize potential risks.
This article reviews recent findings from clinical trials of epothilones and discusses future directions for the use of these agents in cancer therapy, with a focus on the two most-studied epothilones to date: ixabepilone and patupilone.
Discussed herein are selected oral fluorinated pyrimidines that are converted to 5-fluorouracil (5-FU) in vivo to exert antitumor activity. These agents include capecitabine (Xeloda), tegafur-uracil (UFT) plus leucovorin (Orzel), and S-1 (BMS247616). These agents offer the convenience of an orally administered therapy with potentially fewer toxic effects than conventional bolus regimens of 5-FU plus leucovorin. These oral agents provide prolonged 5-FU exposure at lower peak concentrations than observed with bolus intravenous administration of 5-FU and may confer pharmacoeconomic advantages by reducing administration costs and toxicity-related hospitalizations. These regimens also have the potential for improved therapeutic activity by achieving higher 5-FU concentrations in the tumor or by biochemically modulating 5-FU. Phase III trials in patients with advanced colorectal carcinomas are comparing the antitumor activity of these agents with that of intravenous 5-FU plus leucovorin. [ONCOLOGY 12(Suppl 7):48-51, 1998]
Bill, 53 years old and a 3-year survivor of non-Hodgkin’s lymphoma, reflects on his ongoing journey as a cancer survivor: “I was very sick and treatment was very rough, complete with a severe allergic reaction that was difficult to diagnose for a long time. But I made it through to the other shore…remission. Since then, I’ve been trying to rebuild a new life…Living with an 18-year-old [son], I can see how in some ways I’m in a parallel universe…Both of us are looking out at the world before us, at all the many possible options...trying to figure out what we want tomorrow to look like.
The diagnosis and management of cancer in older women is becoming an increasingly common and challenging issue. Women who reach age 65 can expect to live an additional 17 years.[1] Age is an important risk factor for developing cancer. Epidemiologic data from 1992 to 1994 reveal that invasive cancer develops in 1 of 5 women aged 60 to 79 years.[2]
This timely manuscript by Bunnell and Shulman highlights critical issues that challenge our ability to provide care to cancer patients in the next 20 years. Each of the concerns the authors identify has a momentum of its own. In combination, they have the makings of a perfect health care storm. The time to further address these matters is now.
The field of palliative care hasgrown rapidly in recent yearsin response to patient need andclinician interest in effective approachesto managing chronic andlife-threatening illness. The article byKhatcheressian et al reviews the datathat make the case for palliative careas a core component of modern oncologypractice. They point out thatthe issue is not whether we have aquality problem here-it is clear thatwe do. Rather, the focus of this articleis on how best to address that problemin the context of the very real time andfinancial constraints in which we nowpractice oncology in the United States.
Chemotherapy has had limited success in biliary tract cancer. Of thenewer agents, gemcitabine (Gemzar) and irinotecan (CPT-11, Camptosar)both have single-agent activity in patients with advanced disease.We conducted a phase II trial to study the efficacy and toxicity of thecombination of gemcitabine plus irinotecan in patients with locallyadvanced or metastatic biliary tract cancer. The study has enrolled 14patients with histologically or cytologically documented cancer of thebiliary tract or gallbladder with bidimensionally measurable disease,Eastern Cooperative Oncology Group performance status 0 or 1,decompressed biliary tree, and no prior exposure to chemotherapy.Gemcitabine at 1,000 mg/m2 and irinotecan at 100 mg/m2 were bothadministered on days 1 and 8, every 21 days. In patients who had lessthan grade 3 hematologic and less than grade 2 nonhematologic toxicityfollowing cycle 1, the dose of irinotecan was increased to 115 mg/m2 forsubsequent cycles. A total of 65 cycles of chemotherapy have beenadministered, with an average of 4.5 cycles per patient (range: 1 to 11cycles). The median treatment duration was 3 months (range: 0.75 to 8months). An objective partial response was determined radiographicallyin two patients (14%) while stable disease for periods ranging from 4to 11.5 months was noted in six patients (43%). Toxicity consisted ofgrade 3/4 neutropenia in seven patients (50%) with no episodes offebrile neutropenia, grade 3/4 thrombocytopenia in four (28%), grade3 diarrhea in two (14%), and grade 3 nausea in one patient. Thecombination of gemcitabine plus irinotecan appears to possess modestclinical activity, and it is well tolerated in patients with advanced biliarycancer. Patient accrual is ongoing to this study.
Diane M. Simeone, MD highlights the importance of multidisciplinary care, surgical practices, and early detection in pancreatic cancer care.
The National Coalition for Cancer Survivorship (NCCS) recently surveyed health providers, government officials, professional and advocacy organizations, scientists, and others regarding a critical issue facing this nation's 8 million cancer survivors: quality cancer care. The responses were illuminating as they portrayed a system in flux. The United States is moving away from a health care system where fee for service insurance plans predominate to one where market-based alternatives are quickly gaining favor among employers, consumers, and other purchasers of health care coverage. What this fundamental transition will mean for survivors and individuals with other serious or life-threatening diseases and the people who care for them is an open question with important public policy implications

Squamous cell carcinomas of the head and neck are highly responsiveto induction chemotherapy. However, randomized trials have failedto demonstrate a survival advantage with the addition of induction chemotherapyto locoregional therapy consisting of surgery and/or radiationtherapy. Currently, concomitant radiation and chemotherapy hasemerged as a standard and has optimized locoregional control in headand neck cancer. In this setting, the addition of induction chemotherapymay further improve outcome by enhancing both locoregional and distantcontrol. As interest in induction regimens is renewed, we elected toconduct a systematic review of trials of induction chemotherapy forlocoregionally advanced head and neck cancer. The most studied combination-cisplatin plus fluorouracil (5-FU)-achieves objective responserates of about 80%. In a meta-analysis, induction with platinum/5-FU resulted in a small survival advantage over locoregionaltherapy alone. The introduction of a taxane into induction chemotherapyregimens has produced promising results. Induction chemotherapyshould be the subject of further clinical research in head andneck cancer. Randomized clinical trials in which the control arm isconcurrent chemoradiotherapy and the experimental arm is inductionchemotherapy followed by concurrent chemoradiotherapy are planned.Platinum/taxane combinations are the preferred regimens for furtherstudy in the induction setting and a suitable platform with which toinvestigate the addition of novel targeted agents.
