What distinguishes those practices that are successful in their use of the EMR is their commitment to the product and their recognition that it is the central element in the treatment of their patients.
Aggressive cancer therapy places patients at greater risk for oral complications and treatment-related consequences. Unfortunately, prevention and/or treatment of such oral sequelae have become often overlooked priorities of the treatment team.
Melanoma frequently metastasizes to the small bowel. In this installment of Clinical Quandaries, we describe the case of 74-year-old man who presented with this rare but well described manifestation of malignant melanoma
Tositumomab/iodine-131 tositumomab (Bexxar) and ibritumomab tiuxetan (Zevalin) are radioimmunoconjugates targeting the CD20 antigen. Both agents are approved in the United States for use in relapsed or refractory, indolent or transformed, B-cell lymphoma. These agents are well tolerated and have the highest levels of single-agent activity observed in these histologies. This review will summarize the key trials that led to approval of both I-131 tositumomab and ibritumomab tiuxetan, and then focus on four novel therapeutic concepts in radioimmunotherapy: retreatment, therapy of de novo indolent lymphoma, therapy of aggressive histologies, and incorporation in high-dose therapy programs utilizing autologous stem cell support.
Cancer treatments often cause sexual dysfunctions that remain severe long after therapy is over. Nevertheless, sexual counseling is not routinely provided in most oncology treatment settings. Most patients and their partners can benefit from brief counseling that includes education on the impact of cancer treatment on sexual functioning; suggestions on resuming sex comfortably and improving sexual communication; advice on how to mitigate the effects of physical handicaps, such as having an ostomy, on sexuality; and self-help strategies to overcome specific sexual problems, such as pain with intercourse or loss of sexual desire. Brief counseling can be provided by one of the allied health professionals on the oncology treatment team. A minority of patients will need specialized, intensive medical or psychological treatment for a sexual dysfunction. In a large cancer center, such treatment could be provided as part of a reproductive health clinic serving the special needs of cancer patients. In smaller settings, the oncologist should build a referral network of specialists. Not all managed care organizations reimburse for these services, however. [ONCCOLOGY 13(11):1585-1591, 1999]
Paragangliomas most commonly occur in the carotid body, jugulotympanicarea, and vagus nerve but have also been reported in otherareas of the head and neck. These tumors are highly vascular andcharacteristically have early blood vessel and neural involvement,making their treatment particularly challenging. Surgery has traditionallybeen the preferred method of treatment, especially in light of recentadvances in technique. However, compared to radiation therapy, it canresult in a higher incidence of cranial nerve dysfunction. Radiationtherapy has the advantage of avoiding the increased morbidity ofsurgery while offering an equal possibility of cure. Part 2 of this articlediscusses radiation therapy as primary treatment of patients who areineligible for surgery and the elderly and infirm. Results with radiotherapyare comparable to those achieved with surgery. The efficacy ofsalvage therapy with either surgery or radiation is discussed, and atreatment algorithm for these tumors is proposed.
By adjusting the sequencing of currently available treatments, improved compliance with therapy is ensured, and novel scientific and clinically relevant hypotheses can be further explored.
High-grade urothelial cancer ofthe bladder is not only relativelycommon but unfortunately,is frequently lethal. These tumorsare often diagnosed when thetumors have already invaded the wallof the bladder. Even when they arediagnosed at a time when they areconfined to the mucosa or lamina propria,patients may not respond to abladder-preservation approach. Oftena radical cystectomy with urinary diversionis either not offered at all or notconsidered until the cancer has invadeddeep into the muscularis propria andlocal treatment fails.
The article by Drs. Levy and Wiersema is an excellent overview of the indications, technical nuances, and efficacy of endoscopic ultrasound in the diagnosis and staging of pancreatic neoplasms. Endoscopic ultrasonography was introduced into the diagnostic armamentarium for gastroenterology approximately 15 years ago. Although the literature suggests a general increase in the utility and experience with endoscopic ultrasound, the technique remains most effective in the hands of experienced experts like Drs. Levy and Wiersema. Their article is a complete and thorough review of the indications and expected accuracy of the technique when evaluating a variety of different pancreatic lesions.
Repeat lumpectomy and retreatment radiotherapy following ipsilateral breast tumor recurrence (IBTR) by either external-beam irradiation or brachytherapy in lieu of salvage mastectomy is an area of significant recent clinical interest. Multiple authors have reported their results, with encouraging numbers of patients avoiding mastectomy.[1‑4]
This review covers progress to date in the identification of molecular targets on blood vessels in cancers, as well as agents that act on those targets, with emphasis on those currently in clinical trials. Current vascular-targeting therapies comprise two general types—antiangiogenic therapy and antivascular therapy. Advances in antiangiogenic therapies, particularly inhibitors of vascular endothelial growth factors and their receptors, have clarified the capacity of these inhibitors to change tumor-associated vessel structure to a more normal state, thereby improving the ability of chemotherapeutics to access the tumors. The responses of other antiangiogenesis target molecules in humans are more complicated; for example, αvβ3 integrins are known to stimulate as well as inhibit angiogenesis, and cleavage of various extracellular proteins/proteoglycans by matrix metalloproteinases produces potent regulators of the angiogenic process. Antivascular therapies disrupt established blood vessels in solid tumors and often involve the use of ligand-based or small-molecule agents. Ligand-based agents, irrespective of the antiangiogenic capacity of the ligand, target antivascular effectors to molecules expressed specifically on blood vessels, such as aminopeptidase N, fibronectin extra-domain B, and prostate-specific membrane antigen. Small-molecule antivascular agents, which are not targeted to molecules on blood vessels, rely on physical differences between the vasculatures in tumors and those in normal tissues.
It is clear that the management of adult patients with ALL is an area in which little progress has been made in the last 30 years. Given the disappointing outcomes, the field is one that lends itself to the study of the incorporation of novel agents, including monoclonal antibodies and tyrosine kinase and proteasome inhibitors, as well as to further study of allogeneic transplant.
Gemcitabine (Gemzar) (2-deoxy-2,2-difluorocytidine) is a new antimetabolite being increasingly used in the treatment of solid tumors. It is an analog of deoxycytidine and cytosine arabinoside (Ara-C) (Figure 1) that has shown significant activity
The aim of this review is to summarize the current knowledge on HSCT in CLL and to discuss critically its role in the age of novel treatment strategies.
Infusion reactions (IRs) can be broadly categorized by their immunologic mechanism. Anaphylaxis is a systemic, immediate hypersensitivity reaction mediated by factors released from interactions between immunoglobulin E (IgE) and mast cells that produce an antigen-antibody reaction.[1] Anaphylactoid reactions can be differentiated from anaphlaxis by the fact that they are not IgE-mediated but rather cytokine-mediated.
Brain metastases arising from breast cancer constitute a clinically unmet need and a situation that portends a poor prognosis with few therapeutic options.
The patient, L.E., is a 72-year-old white male who has been under our care for 10 years. He initially presented to our clinic in 1992, with a diagnosis of localized prostate cancer.
The purpose of this review is to familiarize oncologists with the clinical and pathologic features of this relatively rare disease spectrum. This should enable appropriate clinical management and reassurance of patients concerned about their prognosis.
Ovarian cancer is the deadliestof the gynecologic malignancies.Approximately threequartersof patients present with advanced-stage disease. With aggressivecytoreductive surgery followed byplatinum-based chemotherapy, mostpatients will achieve remission. Despitethis initially good response totreatment, most patients experiencerecurrence and ultimately die of theirdisease. Novel treatment strategies areneeded. Molecularly targeted therapiesoffer the promise of improvedefficacy with decreased toxicity. Inthis article, Drs. Stephanie Blank, RichardChang, and Franco Muggiapresent an excellent summary of thecurrent status of epidermal growth factorreceptor (EGFR) inhibitors in thetreatment of ovarian cancer. They describethe promise of these drugs aswell as some of the questions regardingthe best way to integrate theminto therapy for ovarian cancer.
In this interview we discuss the direct-to-consumer advertising for nivolumab (Opdivo) for the treatment patients with advanced non-small-cell lung cancer.
The majority of women with ovarian cancer present with advanced-stage disease. Women with early-stage ovarian cancer have a much better chance of achieving a cure than do women with late-stage disease. This
Colorectal cancer is one of the most commonly occurring cancers in the United States. In an effort to prevent the occurrence of colorectal cancer, agents identified as reducing risk of the disease are being targeted as potential chemoprevention tools. However, complex associations exist among diet, lifestyle factors, and genetic susceptibility and the eventual development of colon cancer, sometimes making the transition from associations identified in epidemiologic studies to the clinical use of chemoprevention agents difficult. Environmental factors that may serve as chemoprevention agents are addressed in the article by Garay and Engstrom. Does our current knowledge allow us to embrace these agents as tools for chemoprevention?
Multiple myeloma is now the most common indication for autologous stem cell transplantation (ASCT) in North America, with over 5,000 transplants performed yearly (Center for International Blood and Marrow Transplant Research [CIBMTR] data). While the role of ASCT as initial therapy in multiple myeloma has been established by randomized studies, newer therapies are challenging the traditional paradigm. The availability of novel induction agents and newer risk stratification tools, and the increasing recognition of durability of remissions are changing the treatment paradigm. However, even with arduous therapy designed to produce more complete remissions—for example, tandem autologous transplants—we have seen no plateau in survival curves. A tandem autologous procedure followed by maintenance therapy may be performed in an attempt to sustain remission. Sequential autologous transplants followed by nonmyeloablative allotransplants are pursued with the hope of "curing" multiple myeloma. We examine how the key challenges of increasing the response rates and maintaining responses are being addressed using more effective induction and/or consolidation treatments and the need for maintenance therapies after ASCT. We argue that given the biologic heterogeneity of multiple myeloma, risk-adapted transplant approaches are warranted. While the role of curative-intent, dose-intense toxic therapy is still controversial, conventional myeloablative allogeneic transplants need to be reexamined as an option in high-risk aggressive myeloma, given improvements in supportive care and transplant-related mortality.
The patient is a 5-month-old Caucasian boy with no developmental abnormalities who presented Christmas Eve 2004 to his pediatrician with increasing fussiness, emesis, and inability to tolerate oral intake. He had a temperature of 100.2°F but otherwise normal vital signs. Physical exam at that time revealed a distended abdomen. He was sent home with a diagnosis of viral gastroenteritis.
This review will summarize the current standard of care; key issues that arise when treating patients with HER2-positive disease; and developments in novel therapeutics, including small-molecule inhibitors, nanoparticles, immunotherapy, and agents targeting resistance pathways.
A comprehensive textbook on clinical oncology should have broad appeal to readers from various disciplines, including educators, clinicians, and scientists working with cancer patients. Students of the medical disciplines must also have a reference textbook to guide them in their educational exploration, whether they are in the field of medicine itself or in complementary areas. We look to comprehensive textbooks not only to provide us with the latest updates in different disease entities, but also to guide us by choosing the most relevant areas of study and investigation. The editors who compiled this textbook have met these challenges, while maintaining a readability that is suitable for various levels of expertise and comprehension
The patient is an otherwise healthy male transferred from an outside hospital with a newly diagnosed melanoma from an unknown primary presenting as a large, left axillary mass.
Martin Dreyling, MD, spoke about the potential use of CAR T-cell therapy in earlier treatment stages for certain patient groups with mantle cell lymphoma.
Several novel targeted agents are being tested for the treatment of advanced renal cell carcinoma (RCC), and results of phase I and II trials have been encouraging. A recently completed phase III, placebo-controlled study showed that median progression-free survival doubled from 12 weeks to 24 weeks in patients treated with the multi-kinase inhibitor sorafenib (Nexavar) (hazard ratio [HR], 0.44; P < .00001), and approximately three-quarters of patients had some degree of tumor regression. Furthermore, interim analysis showed an estimated 39% improvement in overall survival in sorafenib-treated patients (HR, 0.72; P = .018) and an investigator-assessed response rate of 10%, indicating that many more patients had clinical benefit than had tumor regression qualifying as response by traditional criteria. These data and others have added to the evidence of lack of correlation between response rate and clinical benefit in RCC patients (as well as in other tumor types) treated with targeted therapies. Issues surrounding study endpoints and biologic efficacy markers for molecular targeted agents in RCC are discussed in this article, with a focus on results of the Treatment Approaches in Renal Cancer Global Evaluation Trial (TARGETs).
I work with medical oncologists/hematologists across the country in both the private practice and hospital settings. Based on my company’s experience, I would like to point out a couple of key flaws in the current Medicare code interpretations.
