Adult T-cell Leukemia/ Lymphoma: Complexities in Diagnosis and Novel Treatment StrategiesIn this issue of ONCOLOGY, Dr. Tobinai presents a thorough and thoughtful review of the current state of the art of HTLV-related adult T-cell leukemia/lymphoma (ATLL). As described, ATLL is most prevalent in Asia, where it has also been most studied, but is also seen in patients from other HTLV-endemic areas including the Caribbean, South America, and parts of Africa. ATLL is rare in North America and Europe, representing 1% to 2% of T-cell lymphomas compared to 25% in Asia.[1]

Proposed Algorithm for Managing Ibrutinib-Related Atrial FibrillationAlthough ibrutinib-related atrial fibrillation (IRAF) occurs in up to 11% of patients in clinical trials, these studies have rarely fully characterized bleeding events or risk factors for bleeding when ibrutinib is combined with anticoagulation. Furthermore, guidelines do not provide direction regarding the preferred anti-arrhythmic agent for IRAF.

Proton Therapy for Lung Cancer: New Data to ConsiderThe role of radiation therapy (RT) in lung cancer is long established; some of the earliest Radiation Therapy Oncology Group reports dealt with non-small cell lung cancer (NSCLC).[1,2] More recently, the advent of stereotactic body RT (SBRT) techniques has provided significant local control rates after focused treatment of selected small metastases and inoperable early stage lesions.[3,4] Our center has been in the forefront of examining SBRT and its role in central [5] or bilateral [6] lesions, its effect on PET imaging [7] and pulmonary function testing,[8] and subsequent frequency of brachial plexopathy,[9] chest wall toxicity,[10] or pneumonitis.[11] Still, even this highly conformal technique comes with potentially significant dose to adjacent normal tissue. This is in the context of an emerging appreciation for the pulmonary consequences of elevated mean lung dose,[12] or V5 after pneumonectomy.[13] For each lung cancer patient requiring RT, an effective mechanism to deliver dose to the tumor while minimizing dose to uninvolved lung is called for.

Hematopoietic growth factorsFor years, chemotherapy-associated myelosuppression has represented a major limitation to a patient’s tolerance of anticancer therapy. In addition, the clinical consequences of chemotherapy-induced myelosuppression (such as febrile neutropenia, dose reductions, or lengthy dose delays) may have had significant negative effects on quality of life or even response to treatment.

Ovarian Tumors of Low Malignant PotentialThe Trimbles have provided auseful overview of the majorclinical and pathobiologic issuesinvolving ovarian borderlinetumors (also termed atypical proliferativetumors or tumors of low malignantpotential). The borderline category ofovarian tumors comprises a heterogeneousgroup of neoplasms that, whensubdivided according to histologicappearance and the presence of peritoneallesions, form distinctive subgroups,each with characteristicpathologic features and a distinctiveclinical course. Thus, retrospectivereviews of thousands of reported caseshave shown that borderline tumors ofall types that are confined to the ovaries(ie, lack peritoneal “implants”)are associated with virtually 100%survival and an extremely low recurrencerate.[1]

Commentary (Olson): Extended Transbasal Approach to Skull Base TumorsIn this manuscript, Drs. Chandlerand Silva describe the extendedtransbasal approach as a modificationof the commonly used frontoorbitalcraniotomy, which maximizesanterior skull base exposure whileminimizing brain retraction. This conceptis now in its ninth decade, havingbeen described by Frazier inrudimentary form in 1913.[1] The approachwas subsequently reported ina more formalized fashion in the Europeanliterature by Derome and thenexpanded upon by various surgeonsin the United States.[2-4]

Targeted Focal Therapy in Prostate Cancer: Too Soon for a Paradigm ShiftThe morbidities associated with prostate cancer treatments have improved over the years. However, potential overtreatment and the risks of adverse events associated with radical treatment still pose a considerable challenge. Targeted focal therapy (TFT) of prostate cancer appears to be part of a logical continuum in the quest to improve upon the management of early organ-confined disease. TFT is a procedure in which only the cancer in the gland is ablated. The normal gland, sphincter, and in most cases the neurovascular bundles are preserved. Therefore, this approach averts some of the common complications of more radical therapy. Initial experience has been encouraging; however, long-term data and full implementation of emerging advances in imaging are urgently needed before the widespread adoption of this approach. In this review, we present the current status of our knowledge about this procedure and the most important challenges that need to be addressed. We also present the initial results with this approach at our center.

Complications of Androgen Deprivation Therapy: Prevention and TreatmentAndrogen deprivation, as a form of treatment for prostate cancer,has been used for decades. Within the last decade, however, its use hasincreased significantly. Therefore, it is incumbent upon the physicianto be familiar with the side effects associated with this treatment. Someof these side effects (eg, osteoporosis, changes in lipid profiles, andanemia) may be associated with significant morbidity, whereas others(eg, impotence, decreased libido, fatigue, and hot flashes) primarilyaffect the patient’s quality of life. Prevention strategies and treatmentsexist for many of these side effects. In addition, alternative forms ofantiandrogen therapy such as intermittent hormone ablation andantiandrogen monotherapy may be effective, with the added benefit ofminimizing side effects. This review focuses on the wide range of sideeffects associated with androgen ablation as well as preventive and treatmentstrategies.

Multidisciplinary Management of Resectable Rectal CancerThis review nicely summarizes the current state of combined-modality therapy for resectable rectal cancer, largely covering trials currently in progress in the United States. Although the article's title is "Multidisciplinary management of resectable rectal cancer," it really doesn't emphasize how multiple specialists manage rectal cancer patients per se, and thus, the article would probably be more appropriately titled, "Combined-modality therapy in resectable rectal cancer." It would have been interesting if the article had included more details on how radiation oncologists, medical oncologists, and surgeons can cooperate to deliver combined-modality therapy in higher proportions of patients with resectable rectal cancer, but this is a minor criticism.

Nonmyeloablative Preparative Regimens for Allogeneic Hematopoietic TransplantationHigh-dose myeloablative therapy with allogeneic hematopoietictransplantation is an effective treatment for hematologic malignancies,but this approach is associated with a high risk of complications.The use of relatively nontoxic, nonmyeloablative, or reduced-intensitypreparative regimens still allows engraftment and the generation ofgraft-vs-malignancy effects, is potentially curative for susceptiblemalignancies, and reduces the risk of treatment-related morbidity.Two general strategies along these lines have emerged, based on theuse of (1) immunosuppressive chemotherapeutic drugs, usually apurine analog in combination with an alkylating agent, and (2) lowdosetotal body irradiation, alone or in combination with fludarabine(Fludara).

Hyperthermia and Intravesical Therapy: Emerging One-Two Punch for Bladder Cancer?Bladder cancer is the fourth most common cancer (excluding skin cancer) in the United States and ranks eighth as a cause of death from cancer among men; there will be an estimated 70,530 new cases and 14,680 cancer-related deaths in the United States in 2010.[1] Of new cases, 70% to 80% present with non–muscle-invasive bladder cancer (NMIBC). Despite endoscopic and intravesical treatments with curative intent, 50% to 70% of these cancers recur, usually within 5 years, and 10% to 30% progress to muscle-invasive disease, in the majority of cases as high-grade lesions.[2,3] Bladder cancer poses a significant economic burden due to the cost of the lifetime need for surveillance, the need to treat recurrent tumors, and the cost of complications associated with treatment. Medicare estimates have ranked bladder cancer treatment the seventh costliest among cancers, with a 5-year net cost of approximately one billion dollars.[4]
