Diagnosis and Management of Mycosis FungoidesMycosis 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.

Clinical Status and Optimal Use of the Cardioprotectant, DexrazoxaneThere are many challenges facing those involved in chemotherapy drug development. In addition to identification of new agents, clinical investigators must address questions regarding the optimal methods of administration of established agents so as to maximize efficacy and minimize toxicity. Treatment toxicity affects not only morbidity and mortality but also issues of dose intensity, quality of life, and health-care costs. Therefore, there is great interest in preventing the side effects associated with chemotherapy.

Update on Adjuvant Interferon Therapy for High-Risk MelanomaTwo of the most important predictors of relapse (and, therefore, survival) in patients with melanoma are the Breslow thickness of the primary melanoma and regional lymph node involvement. Patients with melanomas greater than 4 mm in thickness have approximately a 50% risk of recurrence, and those with lymph node involvement have a 50% to 85% risk of recurrence depending on the number of lymph nodes involved. Thus, a group of patients can be identified who are at high risk of death from melanoma and are, therefore, appropriate candidates for postsurgical adjuvant therapy.

Evaluation and Definitive Management of Medically Inoperable Early-Stage Non-Small-Cell Lung Cancer: Part 2Lung cancer is estimated to be the second most commonly diagnosed cancer in both men and women in 2006, and the leading cause of cancer mortality. Non-small-cell lung cancer represents the majority of such cases. Most of these patients have locally advanced disease at presentation and are not eligible for curative resection. For the minority of patients who are technically resectable at presentation, lobectomy or pneumonectomy and pathologic mediastinal nodal staging offer the best overall survival. The high rate of comorbid medical illness and poor baseline pulmonary function in this population, however, make many such early-stage patients medically inoperable. For these patients, conventional single-modality radiotherapy has been the primary definitive treatment option, as discussed in part 1 of this article, which appeared in last month's issue. Numerous retrospective reports demonstrate long-term disease-free and overall survival data that are modestly superior to that expected after observation, but both local and distant failure continue to be significant risks. Investigation of radiotherapy dose escalation is ongoing, in an effort to improve local control while maintaining minimal toxicity. Additionally, emerging evidence suggests that new modalities, such as stereotactic radiosurgery and radiofrequency ablation, may also be potentially curative treatment alternatives. These modalities are addressed in part 2.

ASCO: An Epidemic of Contralateral Prophylactic MastectomyWhile overall mastectomy rates have dropped in recent years, more and more women with cancer in one breast are opting to have both breasts removed. The trend has left many researchers questioning whether contralateral prophylactic mastectomy (CPM) is getting overused, or if it simply reflects a better recognition by both patients and physicians of who is likely to develop breast cancer.

Predicting Prognosis in Patients With Superficial Bladder CancerSuperficial transitional cell carcinoma of the bladder comprises an extremely heterogeneous group of tumors, both in terms of morphology and, even more importantly, in terms of tumor biology and clinical behavior. Drs. deVere White and Stapp provide a succinct overview of the challenges encountered clinically because of tumor heterogeneity and the availability of different treatment options. The authors also outline the use of traditional prognostic factors (clinicopathologic characteristics) and the current state of development of biological markers that hold promise in providing significant clinically useful prognostic information.

Treating Bladder Cancer: Neoadjuvant vs Adjuvant TherapyOccult distant micrometastasis at the time of radical cystectomy leads predominantly to distant failures in patients with locally advanced muscle-invasive transitional cell carcinoma of the bladder. Cisplatin-based combination chemotherapy enhances survival in patients with metastatic urothelial cancer. Studies evaluating adjuvant chemotherapy have been limited by inadequate statistical power. However, randomized clinical trials have demonstrated a survival benefit for neoadjvuant cisplatin-based combination chemotherapy, which should be considered a standard of care. In addition, neoadjuvant therapy may assist in the rapid development of novel systemic therapy regimens, since pathologic complete remission appears to be a powerful prognostic factor for long-term outcomes. Patients who are either unfit for or refuse radical cystectomy may benefit from neoadjuvant chemotherapy with or without radiation to enable bladder preservation.

Combination Intravesical Hyperthermia and Chemotherapy for Bladder CancerThe review by Rampersaud and colleagues provides an excellent summary of the scientific rationale for using hyperthermia to treat cancer and of the current status of combinations of hyperthermia and chemotherapy or radiotherapy. In view of the demonstrated efficacy of the combination of intravescial hyperthermia and mitomycin C (MMC) therapy in preventing the progression and recurrence of non–muscle-invading bladder cancer (NMIBC) in several clinical trials, Rampersaud and colleagues advocate additional studies to further optimize the delivery of hyperthermia and to delineate its clinical utility in this disease.

If DNA testing shows that a family member is a gene carrier, that individual's lifetime cancer risk is approximately 90%. If the test is negative, the family member's cancer risk drops to that of the general population.
