Interstitial Brachytherapy Should Be Standard of Care for Treatment of High-Risk Prostate CancerGiven the poor outcomes observed with radical prostatectomy (RP) and external-beam radiation therapy (EBRT), some in the urologic community contend that high-risk disease is not curable with currently available treatment strategies.[1,2] In fact, there is a growing contingent of clinicians who advocate the use of chemotherapy in conjunction with RP. With the established efficacy of brachytherapy, these efforts are likely excessive.

Response to Antiangiogenesis Therapy in a Patient With Advanced Adult-Type Testicular Granulosa Cell TumorWe have presented the first case of a patient with metastatic ATGCT with peritoneal carcinomatosis, who responded to treatment with a VEGFR tyrosine kinase inhibitor. Because of the relative paucity of such cases in the literature, no clear treatment strategy exists. For patients with metastatic ATGCT, enrollment in clinical trials testing novel therapies, including angiogenesis inhibitors, is a reasonable option.

Preclinical Studies Using the Intratumoral Aromatase Model for Postmenopausal Breast CancerTo determine the most effective strategies for the treatment of postmenopausal hormone dependent breast cancer, we recently developed a model system in nude mice. In this model, estrogen receptor-positive human breast cancer cells (MCF-7) stably transfected with the aromatase gene are inoculated into ovariectomized, immunosuppressed (nude) mice.

Limited-Stage Small-Cell Lung Cancer: Therapeutic OptionsAlmost 40% of patients with newly diagnosed small-cell lung cancer (SCLC) have disease confined to the ipsilateral hemithorax and within a single radiation port, ie, limited-stage disease. The median survival for this group of patients after treatment is approximately 15 months, with one in every four patients surviving 2 years. Current optimal treatment consists of chemotherapy with platinum/etoposide, given concurrently with thoracic radiation. Surgery may represent an option for very early-stage disease, but its added value is uncertain. Prophylactic cranial irradiation (PCI) is used for patients with limited-stage SCLC who have achieved a complete response following initial therapy, as it decreases the risk of brain metastases and provides an overall survival benefit. Newer targeted agents are currently being evaluated in this disease and hold the promise of improving current outcomes seen in patients with early-stage disease.

Recurrent Pancreatic Adenocarcinoma After Pancreatic ResectionThe University of Colorado Denver School of Medicine faculty hold weekly second opinion conferences focusing on cancer cases that represent most major cancer sites. Patients seen for second opinions are evaluated by an oncologic specialist. Their history, pathology, and radiographs are reviewed during the multidisciplinary conference, and then specific recommendations are made. These cases are usually challenging, and these conferences provide an outstanding educational opportunity for staff, fellows, and residents in training.The second opinion conferences include actual cases from genitourinary, lung, melanoma, breast, neurosurgery, gastrointestinal, and medical oncology. On an occasional basis, ONCOLOGY will publish the more interesting case discussions and the resultant recommendations. We would appreciate your feedback; please contact us at second.opinion@uchsc.edu.

Palliation of Colorectal Cancer: New Possibilities and ChallengesOver the past decade, new cytotoxic and biologic therapies beyond the old standard-of-care, biomodulated fluorouracil (5-FU), have become available for the treatment of metastatic colorectal cancer (mCRC). The introductions of irinotecan (Camptosar), oxaliplatin (Eloxatin), and bevacizumab (Avastin) have prolonged survival, but the optimal use of these new therapies remains to be determined. Issues remain regarding management of toxicities, treatment of elderly patients or those with poor performance status, and the duration of treatment with front-line therapy. This article reviews recent and ongoing studies of newer therapies in an effort to determine the best use of these drugs in the treatment of mCRC. Current data support the front-line use of bevacizumab added to either 5-FU/leucovorin alone or 5-FU/leucovorin in combination with oxaliplatin (FOLFOX/bevacizumab) or irinotecan (FOLFIRI/bevacizumab). If oxaliplatin is used in first-line therapy, oxaliplatin should be discontinued before the development of severe neurotoxicity and be reintroduced or replaced with irinotecan on disease progression. Definitive conclusions on the sequence and duration of front-line therapy and the most effective strategy to ameliorate toxicity await results of ongoing prospective clinical trials.

Synopsis of Angiogenesis Inhibitors in OncologyAngiogenesis is a dynamic process essential for primary tumor growth and metastases. New insights into the basic understanding of the biologic processes responsible for angiogenesis have led to the characterization of potential therapeutic targets. Several strategies for the development of antiangiogenic therapeutic modalities have been employed, including agents that (1) decrease the activity of specific angiogenic factors, (2) decrease the activity of endothelial survival factors, (3) increase the activity of naturally occurring antiangiogenic agents, or (4) indirectly downregulate angiogenic and survival factor activity.

Nutrition During and After Cancer TherapyIn 2008, roughly 1.44 million Americans were diagnosed with cancer,[1] and accordingly were labeled as “cancer survivors.” Fortunately, for roughly 65% of those who were newly diagnosed, this label will expand to encompass issues of long-term survivorship and health maintenance.[2] Extended cancer survivorship is a relatively new concept. In the past, most people who were diagnosed with the disease did not survive it. While longer survival times are a measure of success, the dark side of this victory is that a substantial proportion of these survivors will experience recurrence or second cancers. In addition, many more will go on to develop comorbid conditions such as cardiovascular disease (CVD), diabetes, or osteoporosis, which often kill or debilitate survivors at much higher rates than the cancer itself.[3,4]

A Patient on Targeted Therapy: CetuximabJeff is a 47-year-old white male who presented to his primary care provider complaining of having had swollen lymph nodes in the right neck for 2 months. He also complained of nasal stuffiness and sore throat. Physical exam found lymphadenopathy in the left cervical triangle less than 2 cm in diameter. He smokes about 2 packs of cigarettes a day and has a 60 pack-year history of smoking. He has been a cabinet-maker for almost 20 years. He has no other significant medical history and is not on any regular medications. He is a social drinker and denies any illicit drug use. He was treated with an antibiotic for 10 days, but on return the lymphadenopathy appeared slightly enlarged. He was sent to an ear, nose, and throat specialist who biopsied the nodal mass. Following an extensive workup, he was diagnosed with stage III (T2, N1, M0) squamous cell carcinoma of the nasopharynx.

Mathematical Modeling for Breast Cancer Risk AssessmentWomen at increased risk of breast cancer have important opportunities for early detection and prevention. There are, however, serious drawbacks to the available interventions. The magnitude of breast cancer risk is a crucial factor in the optimization of medical benefit when considering the efficacy of risk-reduction methods, the adverse effects of intervention, and economic and quality-of-life outcomes. Breast cancer risk assessment has become increasingly quantitative and is amenable to computerization. The assembly of risk factor information into practical, quantitative models for clinical and scientific use is relatively advanced for breast cancer, and represents a paradigm for broader risk management in medicine. Using a case-based approach, we will summarize the major breast cancer risk assessment models, compare and contrast their utility, and illustrate the role of genetic testing in risk management. Important considerations relevant to clinical oncology practice include the role of risk assessment in cancer prevention, the logistics of implementing risk assessment, the ramifications of conveying risk information with limited genetic counseling, and the mechanisms for genetics referral. Medical professionals can embrace new preventive medicine techniques more effectively by utilizing quantitative methods to assess their patients’ risks. [ONCOLOGY 16:1082-1099, 2002]
