Phase III RTOG Data Confirm Survival Advantage for Patients With HPV+ Oropharyngeal Ca
June 15th 2010T umor human papillomavirus (HPV) status is confirmed as a strong and independent prognostic factor for survival of patients with oropharyngeal cancer, report investigators for a large phase III trial established by the Radiation Therapy Oncology Group. Results were presented at the 44th annual meeting of the American Society of Clinical Oncology (ASCO abstract 5510) and published in the New England Journal of Medicine on June 7. Investigators performed a retrospective analysis of the association between tumor HPV status and survival among 323 patients with stage III or IV oropharyngeal squamous cell carcinoma who were enrolled in a randomized trial comparing cisplatin therapy combined with either accelerated- or standard-fractionation radiotherapy. Risk of death among patients with HPV-positive vs HPV-negative cancer was compared using a proportional-hazards model.

Diagnosis and Management of Mycosis Fungoides
May 15th 2010Mycosis fungoides (MF), the most common cutaneous T-cell lymphoma, is a low-grade cutaneous lymphoma characterized by skin-homing CD4+ T cells. It is notable for highly symptomatic progressive skin lesions, including patches, plaques, tumors, and erytheroderma, and has a poorer prognosis at later stages. Diagnosis remains difficult owing to MF’s nonspecific skin presentation and identification of the optimal treatment strategy is challenging given the paucity of controlled trials and numerous and emerging treatment options. Management includes topical therapy with the addition of systemic therapy for patients with later-stage disease including tumors; erythroderma; and nodal, visceral, or blood involvement. Topical therapies include mechlorethamine (nitrogen mustard), carmustine (BCNU), steroids, bexarotene gel (Targretin Gel), psoralen plus ultraviolet A (PUVA), ultraviolet B (UVB), and either localized or total skin electron radiotherapy. Systemic therapies include interferon, retinoids, oral bexarotene (Targretin), denileukin diftitox (Ontak), vorinostat (Zolinza), extracorporeal photochemotherapy (photopheresis), and cytotoxic chemotherapy. Herein, we outline clinically relevant aspects of MF, including clinical presentation, pathology, diagnosis, and staging. We describe in detail existing and emerging therapeutics and offer specific recommendations for management of each stage of MF.
EGFR TKIs for Advanced NSCLC: Practical Questions
April 30th 2010The review by Oxnard and Miller provides a thoughtful update on the use of the epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) gefitinib (Iressa) and erlotinib (Tarceva) as front-line therapy in patients with non–small-cell lung cancer (NSCLC).
Management of Anal Cancer in 2010 Part 2: Current Treatment Standards and Future Directions
April 30th 2010The treatment of anal squamous cell cancer with definitive chemoradiation is the gold-standard therapy for localized anal cancer, primarily because of its sphincter-saving and colostomy-sparing potential.
Current Management of Nasal NK/T-cell Lymphoma
April 15th 2010With better disease definition, staging, and monitoring, treatment of extranodal NK/T-cell lymphoma is becoming more rational. A large proportion of patients with localized nasal disease may enjoy prolonged disease-free survival. On the other hand, early HSCT or novel therapy may be recommended for aggressive extranasal disease.
Managing the Patient With Borderline Resectable Lung Cancer
March 15th 2010Despite recent therapeutic advances, lung cancer continues to be one of the leading causes of cancer-related mortality. Of the various histologic subtypes, non–small-cell lung cancer (NSCLC) is the most common-accounting for approximately 85% of all lung cancers-and will be the focus of this article. In general, the treatment of lung cancer may include surgery, radiation therapy, systemic therapy (eg, chemotherapy with or without targeted therapy), or a combination of the above. Surgery continues to offer the best chance of long-term cure. The initial treatment of stage I and II NSCLC usually entails surgical resection, whereas stage IV disease is primarily treated with systemic agents, in light of the lack of curative potential with surgery and/or radiation therapy alone. It is locally advanced NSCLC, including stage IIIA and IIIB disease, that continues to pose a therapeutic dilemma, given its heterogeneous nature.
Cancer Management Chapter 20: Melanoma and other skin cancers
March 9th 2010Skin cancer is the single most common form of cancer, accounting for more than 75% of all cancer diagnoses. More than 1 million cases of squamous cell and basal cell carcinomas are diagnosed annually, with a lifetime risk of more than one in five. The vast majority of skin cancers can be cured with surgery alone. Resection is the mainstay of therapy, even for skin cancer involving regional lymph nodes or, in some cases, more distant metastatic sites.
HDAC Inhibitors in Cancer Care
February 16th 2010The epigenetic control of gene expression has been shown to play an important role in cancer initiation, progression, and resistance. Thus, agents that modify the epigenetic environment of tumors will likely be an important addition to the anticancer arsenal. Specifically, there is much interest in modulating histone acetylation using a new class of drugs, histone deacetylase (HDAC) inhibitors. Preclinical data have demonstrated the efficacy of various HDAC inhibitors as anticancer agents, with the greatest effects shown when HDAC inhibitors are used in combination with other therapies. As a result of encouraging preclinical data, numerous HDAC inhibitors are being investigated in clinical trials either as monotherapies or in conjunction with other treatments such as chemotherapy, biologic therapy, or radiation therapy. In fact, vorinostat and depsipeptide, two actively studied HDAC inhibitors, were recently approved for the treatment of refractory cutaneous T-cell lymphoma. Although the use of HDAC inhibitors has generated great enthusiasm, a significant amount of work still needs to be done in order to understand their mechanisms of action, as well as to determine the appropriate patient characteristics and subsets of cancer for which HDAC inhibitors hold the most potential for effective treatment.
HDAC Inhibitors: Much to Learn About Effective Therapy
February 15th 2010Shabason and colleagues’ review of the development of histone deacetylase (HDAC) inhibitors as treatment for cancers is timely, with an emphasis on therapeutic strategies combining HDAC inhibitors and radiation therapy. As the authors indicate, vorinostat (Zolinza)-originally known as suberoylanilide hydroxamic acid, or SAHA-was the first of the HDAC inhibitors approved by the US Food and Drug Administration (FDA) for clinical use in the treatment of cutaneous T-cell lymphoma (CTCL).[1] In November 2009, a second HDAC inhibitor-romidepsin (Istodax)-received FDA approval for the treatment of CTCL. Currently there is a great deal of competition in the HDAC inhibitor field, as several new and, hopefully, more effective compounds are being developed and entering clinical trials.[2]
Monoclonal Antibodies in Advanced B-cell Lymphomas
February 15th 2010he treatment of B-cell malignancies has been revolutionized by the availability of safe and effective monoclonal antibodies. The addition of rituximab to standard chemotherapy regimens prolongs the survival of patients with diffuse large B-cell lymphoma (DLBCL) and follicular non-Hodgkin lymphoma. Nevertheless, indolent and mantle cell lymphomas remain incurable, and 30% to 40% of patients with DLBCL still die from their disease. Much ongoing research has focused on optimizing monoclonal antibody use, integrating them into multiagent regimens, and developing newer antibodies. Attempts to improve on the efficacy of monoclonal antibody–based therapy have included altering the dosing schedule, optimizing patient selection, maintenance therapy, improving upon the rituximab molecule, radioimmunotherapy, as well as combinations with cytotoxic molecules and other novel agents. Preliminary data with a number of treatment regimens are promising in indolent and aggressive lymphomas. The eventual goal of targeted therapies is to individualize treatment to increase response and survival, while reducing treatment-related toxicity.
Improving Our Use and Understanding of Antibodies in B-cell Lymphomas
February 11th 2010In this review, Ujjani and Cheson present a useful overview of the array of existing and developing roles for monoclonal antibodies in the management of B-cell non-Hodgkin lymphomas (NHLs). These roles may be characterized as single-agent antibody therapy, use in combination with chemotherapy and/or other antibodies, and use following an initial regimen (consolidation/maintenance). Rituximab (Rituxan), the first monoclonal antibody approved for B-cell NHL, clearly has had greatest application in each of these arenas, but it has now been joined by alemtuzumab (Campath) and ofatumumab (Arzerra) as approved single-agent therapies. Also highlighted are a number of other antibodies aimed at B-cell targets: veltuzumab, GA101, AME-133 (CD20), epratuzumab (CD22), lumiliximab (CD23), galiximab (CD80), dacetuzumab (CD40), mapatumumab, lexatumumab (TRAIL), and approaches to improve antibody therapy such as conjugation with radioisotopes or toxins.
