Head and Neck Cancer: Changing Epidemiology and Public Health ImplicationsCharacterizing the epidemiology of head and neck cancers is challenging and has received limited attention in the medical literature. Traditionally, 80%–90% of head and neck squamous cell carcinomas (HNSCCs) have been attributed to tobacco and alcohol use, but with growing public awareness and tobacco control efforts over the past few decades, there has been a downward trend in smoking prevalence in the US. There is also emerging evidence that human papillomavirus (HPV) is responsible for inconsistencies in HNSCC trends, with oncogenic HPV DNA found in approximately half of oropharyngeal cancers and in a high proportion of oropharyngeal cancers in nonsmokers and nondrinkers. The risk to HNSCC epidemiology is that whatever gains continue to be made in tobacco control may become lost in the increasing numbers of oropharyngeal cancers due to HPV. The purpose of this review is to explore the changing epidemiology of HNSCC, focusing on how it has been shaped by health policy and advocacy interventions and how it will continue to have public health implications in the future, particularly in considering preventive strategies against HPV. Given that the majority of HNSCCs are the result of exposure to preventable public health risks, more focus should be given to this area.

Predicting Endocrine Responsiveness: Novel Biomarkers on the HorizonHistorically, breast tumor classification and therapeutic decisions have relied on immunohistochemical (IHC) techniques for characterizing biomarkers such as estrogen receptor (ER), progesterone receptor (PR), and the epidermal growth factor receptor 2 (HER2), as described in the review by Ma and colleagues. However, these markers have been found to be inadequate for fully predicting a patient’s response to a given breast cancer treatment such as endocrine therapy.

Rationale for Phase I Study of UFT Plus Leucovorin and Oral JM-216Both cisplatin (Platinol) and fluorouracil (5-FU) have demonstrated single-agent clinical efficacy in a variety of solid neoplasms. The combination of these agents has revealed synergistic cytotoxicity in models in vitro and in vivo, which may explain the clinical effectiveness of 5-FU-cisplatin regimens. UFT (tegafur and uracil) and bis-aceto-ammine-dichloro-cyclohexyl-amine platinum (IV) (JM-216) are novel oral analogues of 5-FU and cisplatin, respectively. In preclinical models, JM-216 has demonstrated equivalent cytotoxicity to cisplatin, while phase I trials suggest its dose-limiting toxicity is myelosuppression. In contrast to cisplatin, JM-216 has not demonstrated significant neurotoxicity or nephrotoxicity. UFT has been used extensively in Japan, where phase II data suggest disease response rates similar to single-agent 5-FU in colorectal, gastric, and breast carcinomas. Combination studies of prolonged administration UFT and single-dose cisplatin have shown efficacy, but also significant hematologic toxicity. We propose a phase I study of UFT and JM-216 administered daily over 14 consecutive days with leucovorin (90 mg/d). Ease of administration and continuous drug exposure are potential advantages of this regimen. Several disease specific investigations may be warranted given demonstrated feasibility in this phase I study.[ONCOLOGY 11(Suppl 10):26-29, 1997]

Contemporary Management of Prostate Cancer With Lethal PotentialScreening for prostate cancer by determining serum prostate-specificantigen (PSA) levels has resulted in a stage migration such thatpatients with high-risk disease are more likely to be candidates for curativelocal therapy. By combining serum PSA, clinical stage, and biopsyinformation-both Gleason score and volume of tumor in the biopsycores-specimen pathologic stage and patient biochemical disease-freesurvival can be estimated. This information can help patients and cliniciansunderstand the severity of disease and the need for multimodaltherapy, often in the context of a clinical trial. While the mainstays oftreatment for local disease control are radical prostatectomy and radiationtherapy, systemic therapy must be considered as well. A randomizedtrial has shown a survival benefit for radical prostatectomy inpatients with positive lymph nodes who undergo immediate adjuvantandrogen deprivation. Clinical trials are needed to clarify whether adjuvantradiation therapy after surgery confers a survival benefit. PSAis a sensitive marker for follow-up after local treatment and has proventhat conventional external-beam irradiation alone is inadequate treatmentfor high-risk disease. Fortunately, the technology of radiationdelivery has been dramatically improved with tools such as three-dimensionalconformal radiation, intensity-modulated radiation therapy,and high-dose-rate brachytherapy. The further contributions of pelvicirradiation and neoadjuvant, concurrent, and adjuvant androgen deprivationtherapy have been defined in clinical trials. Future managementof high-risk prostate cancer may be expanded by clinical trialsevaluating neoadjuvant and/or adjuvant chemotherapy in combinationwith androgen deprivation.

Commentary (Meissner): Diagnosis of Venous Thromboembolic Disease in Cancer PatientsThe diagnosis of venous thromboembolismon the basis ofclinical signs and symptoms isnotoriously inaccurate and, therefore,mandates confirmatory diagnostictesting. Unfortunately, all diagnostictests for deep venous thrombosis(DVT) and pulmonary embolismhave clinical or practical limitations.Contrast venography and pulmonaryarteriography are usually regarded asthe reference standards for the diagnosisof DVT and pulmonary embolism,respectively. However, evencontrast venography may be impossibleto perform in 9% to 14% ofpatients, may fail to visualize 10% to30% of venous segments, and maybe associated with postvenographythrombosis in up to 8% of patients.[1]

Multimodality Therapy for Esophageal CancerRecent developments in the epidemiology, staging, and treatment of esophageal and gastroesophageal junction cancers have led to significant changes in the way these malignancies are managed. Although a relationship between gastroesophageal reflux disease and esophageal cancer has been demonstrated, antireflux surgery has been shown to have no preventive effect with regard to the development of esophageal adenocarcinoma. The newly modified staging system of the World Esophageal Cancer Consortium has helped define the optimal number of lymph nodes to dissect during an esophagectomy. Incorporating modern techniques, such as esophageal ultrasound, fine needle aspiration, and positron emission tomography, can improve the prognostic value of staging. Use of higher-volume centers and higher-volume surgeons for the performance of procedures in upper gastrointestinal cancers is associated with better outcomes. Neoadjuvant chemoradiation using a wide variety of chemotherapy regimens appears to have become the new standard of care for stage II and III esophageal cancer.

Chronic Phase Chronic Myeloid Leukemia: More Drugs, More Lives Saved, New ChallengesThe development of imatinib mesylate (Gleevec), a tyrosine kinase inhibitor targeted against the causative Bcr-Abl protein in chronic myeloid leukemia (CML), has resulted in hematologic and cytogenetic remissions in all phases of CML. Following imatinib treatment, more than 90% of patients obtain complete hematologic response, and 70% to 80% achieve a complete cytogenetic response. With 5 years of follow-up, the data are very encouraging, exhibiting a major change in the natural history of the disease. The understanding of at least some of the mechanisms of resistance to imatinib has led to a rapid development of new agents that may overcome this resistance. Combination strategies are currently being investigated in preliminary clinical studies and may prove to be useful. Overall, there are an increasing number of treatment options now available for patients with CML.

Oropharyngeal Mucositis in Cancer TherapyOropharyngeal mucositis is a common and treatment-limiting sideeffect of cancer therapy. Severe oral mucositis can lead to the need tointerrupt or discontinue cancer therapy and thus may have an impacton cure of the primary disease. Mucositis may also increase the risk oflocal and systemic infection and significantly affects quality of life andcost of care. Current care of patients with mucositis is essentially palliativeand includes appropriate oral hygiene, nonirritating diet andoral care products, topical palliative mouth rinses, topical anesthetics,and opioid analgesics. Systemic analgesics are the mainstay of painmanagement. Topical approaches to pain management are under investigation.The literature supports use of benzydamine for prophylaxisof mucositis caused by conventional fractionationated head andneck radiotherapy, and cryotherapy for short–half-life stomatoxic chemotherapy,such as bolus fluorouracil. Continuing studies are investigatingthe potential use of biologic response modifiers and growth factors,including topical and systemic delivery of epithelial growth factorsand agents. Progress in the prevention and management of mucositiswill improve quality of life, reduce cost of care, and facilitate completionof more intensive cancer chemotherapy and radiotherapy protocols. Inaddition, improved management of mucositis may allow implementationof cancer treatment protocols that are currently excessively mucotoxicbut may produce higher cure rates. Continuing research related to thepathogenesis and management of mucositis will undoubtedly lead to thedevelopment of potential interventions and improved patient care.
