Systemic Approaches for Multifocal Bronchioloalveolar Carcinoma: Is There an Appropriate Target?Bronchioloalveolar carcinoma (BAC) is a subset of pulmonary adenocarcinoma characterized by distinct and unique pathological, molecular, radiographic, and clinical features. While the incidence of pure BAC is rare, comprising only 1% to 4% of non–small-cell lung cancer (NSCLC), mixed subtypes (including BAC with focal invasion and adenocarcinoma with BAC features) represent as much as 20% of adenocarcinomas-and that figure may be increasing. Despite the longstanding recognition of this entity, there is no established treatment paradigm for patients with multifocal BAC, resulting in competing approaches and treatment controversies. Current options for multifocal BAC include both surgery and systemic therapies. Unfortunately, prospective data on systemic approaches are limited by study design and small patient numbers; there are only seven phase II studies involving four therapies. This article evaluates key characteristics of BAC, including the current understanding of histopathology and tumor biology. In addition, it comprehensively reviews the systemic phase II studies in an attempt to clarify the therapeutic challenges in this disease. It also includes the first proposed treatment paradigm that integrates both EGFR mutational status and the sub-histologies, mucinous and nonmucinous BAC.

Twenty Years of Systemic Therapy for Breast CancerThe past 2 decades of systemic therapy for breast cancer have beena period of monumental change, in terms of both theory and technology.Adjuvant therapy developed from two strands of research-one insystemic chemotherapy and one in hormonal therapy-both of whichwere aided by the application of higher statistical methodology to clinicaltrials. The agent with the single greatest public health impact inoncology has been tamoxifen, but problems with tamoxifen therapy ledto the development of the aromatase inhibitors, and further researchled to the use of hormonal therapy in a chemopreventive capacity. Theevolution of systemic chemotherapy for breast cancer has been an interplaybetween theory-driven approaches and new agents. By the late1980s, accumulating data revealed that overexpression of HER2 (erbB2)played an important role in a substantial portion of breast cancers,which prompted the development of trastuzumab (Herceptin), an agenttargeting HER2-positive disease. Determining HER2 status proved essentialto assessing patient eligibility for trastuzumab therapy. Decodingof the human genome and application of bioinformatics furtherrevolutionized the possibilities in breast cancer treatment.

Where Expert Opinion Meets Public ResistanceThere is concern and growing evidence that the supply of medical oncologists in the United States will be insufficient to meet the needs of future patients. With an aging population and increasing complexity of cancer therapies, it is clear there will be more patients and that they will live longer and require expert care. It is equally clear that the number of specialists trained in cancer medicine is not growing fast enough to meet projected needs, so new models of care will need to be designed and implemented. Innovation in practice models will require the integration of non-physician practitioners (nurse practitioners and physician assistants) into multidisciplinary teams, broader use of technology to allow virtual consultations and the secure exchange of vital health information, increased utilization of community services, and public acceptance.

Physical Late Effects in Adult Cancer SurvivorsToday there are nearly 12 million individuals living in the United States who have ever received a diagnosis of cancer.[1] This number is growing, having just been recently updated to approximately 11.9 million from a previous estimate of about 10.8 million cancer survivors.[2] One half of all men and one in three women will be diagnosed with cancer in their lifetime, with the largest burden being during later life; one in seven Americans 65 years of age and older has a past or present cancer diagnosis.[3]

Rehabilitation for the Head and Neck Cancer PatientAs the economics of health care increasingly dictate the parameters of patient care delivery, the role of rehabilitation has taken on new meaning with regard to positive patient outcomes. This is particularly true for the head and neck cancer patient coping with devastating physical and functional changes. With treatment advances leading to increased survival, health-care providers must therefore focus on restoring function and assisting the patient to achieve an acceptable quality of life. For the head and neck cancer patient with multiple rehabilitation needs, this can best be accomplished through a comprehensive, coordinated approach, utilizing interdisciplinary clinical and community resources aimed at facilitating the rehabilitation process and ultimately achieving individualized rehabilitation goals.

Treatment of Gynecologic Cancers: From Halsted to the 21st CenturyHalsted first proposed the concept of "radical surgery" for cancer in 1882, theorizing that cancer, along with all of its supporting tissues and regional lymph nodes, needs to be removed en bloc for the best chance of cure. Radical mastectomy with en bloc removal of the axillary nodes and pectoral muscles became the standard treatment for breast cancer. En bloc radical vulvectomy with complete superficial and deep inguniofemoral lymph node dissection became the standard of care for vulvar cancer. Subsequently, unilateral or bilateral pelvic node dissection extended the scope of the regional node dissection for vulvar cancer patients with metastases to groin nodes. Unquestionably, this surgically comprehensive technique improved cancer control rates for patients with locally extensive vulvar cancer, compared to results from piecemeal approaches that characterized surgical therapy in prior eras.

Pathology and Management of Dermatologic Toxicities Associated With Anti-EGFR TherapyAs inhibitors of the epidermal growth factor receptor (EGFR) become an increasingly common therapeutic option in cancer, appropriate management of their associated toxicities emerges as a critical part of treatment. Cutaneous manifestations, probably linked to the function of the EGFR in epithelial development, are the most common adverse reactions to EGFR inhibition. The key manifestations are follicular eruptions, nail disorders, xerosis, and desquamation. Growing attention continues to be devoted to the analysis of these events, particularly given their potential role as markers of responsiveness to treatment. However, to date, there are few evidence-based guidelines for the appropriate management of these dermatologic events. Multidisciplinary collaboration between oncologists and dermatologists will be required to improve our understanding and optimize the characterization of these skin toxicities, and to design effective management approaches.

Rising PSA in Nonmetastatic Prostate CancerRising prostate-specific antigen (PSA) in nonmetastatic prostate cancer occurs in two main clinical settings: (1) rising PSA to signal failed initial local therapy and (2) rising PSA in the setting of early hormone-refractory prostate cancer prior to documented clinical metastases. Most urologists and radiation oncologists are very familiar with the initial very common clinical scenario, commonly called "biochemical recurrence." In fact, up to 70,000 men each year will have a PSA-only recurrence after failed definitive therapy. The ideal salvage therapy for these men is not clear and includes salvage local therapies and systemic approaches, of which the mainstay is hormonal therapy. Treatment needs to be individualized based upon the patient's risk of progression and the likelihood of success and the risks involved with the therapy. It is unknown how many men per year progress with rising PSA while on hormonal therapy without documented metastases. This rising PSA disease state is sometimes called, "PSA-only hormone-refractory prostate cancer." As in the setting of initial biochemical recurrence, evidence-based treatment options are limited, and taking a risk-stratified approach is justified. In this article, we will explore these prostate cancer disease states with an emphasis on practical, clinically applicable approaches.
