The NCCN Clinical Practice Guidelines in Oncology: Non-Hodgkin's Disease were recently revised to include recommendations for treating mycosis fungoides and Sézary syndrome. These uncommon lymphomas require a specialized evaluation and use a unique TNMB staging system. Unlike the other forms of non-Hodgkin's lymphomas, stage overwhelmingly determines prognosis and defines radically different treatment approaches. For patients with early-stage disease, initial treatment with skin-directed therapies is preferred, and many patients never require systemic therapy. For patients with refractory or advanced-stage disease, biologic therapies are often the first choices, whereas chemotherapies are reserved for later in the disease course. Many milder therapies may be repeated several times in the disease course, and maintenance and tapering strategies are common. This article also discusses the emerging role of allogeneic stem cell transplantation.

Basal cell carcinoma (BCC) of the skin is the most common cancer, with a higher incidence than all other malignancies combined. Although it is rare to metastasize, patients with multiple or frequently recurring BCC can suffer substantial comorbidity and be difficult to manage. Assessment of risk is a key element of management needed to inform treatment selection. The overall management of BCC primarily consists of surgical approaches, with radiation therapy as an alternate or adjuvant option. Many superficial therapies for BCC have been explored and continue to be developed, including topicals, cryosurgery, and photodynamic therapy. Two hedgehog pathway inhibitors were recently approved by the FDA for systemic treatment of advanced and metastatic BCC, and others are in development. The NCCN Guidelines for Basal Cell Skin Cancer, published in full herein, include recommendations for selecting among the various surgical approaches based on patient-, lesion-, and disease-specific factors, as well as guidance on when to use radiation therapy, superficial therapies, and hedgehog pathway inhibitors.

Natural killer (NK)/T-cell lymphomas are a rare and distinct subtype of non-Hodgkin's lymphomas. NK/T-cell lymphomas are predominantly extranodal and most of these are nasal type, often localized to the upper aerodigestive tract. Because extranodal NK/T-cell lymphomas (ENKL) are rare malignancies, randomized trials comparing different regimens have not been conducted to date and standard therapy has not yet been established for these patients. These NCCN Guidelines Insights discuss the recommendations for the diagnosis and management of patients with ENKL as outlined in the NCCN Guidelines for T-Cell Lymphomas.

Hepatosplenic T-cell lymphoma (HSTCL) is a rare subtype of T-cell lymphoma associated with an aggressive clinical course and a worse prognosis. HSTCL develops in the setting of chronic immune suppression or immune dysregulation in up to 20% of cases and is most often characterized by spleen, liver, and bone marrow involvement. Diagnosis and management of HSTCL pose significant challenges given the rarity of the disease along with the absence of lymphadenopathy and poor outcome with conventional chemotherapy regimens. These Guidelines Insights focus on the diagnosis and treatment of HSTCL as outlined in the NCCN Guidelines for T-Cell Lymphomas.

Mycosis fungoides (MF) is the most common subtype of cutaneous T-cell lymphoma (CTCL), and Sézary syndrome (SS) is a rare erythrodermic and leukemic subtype of CTCL characterized by significant blood involvement. Although early-stage disease can be effectively treated predominantly with skin-directed therapies, systemic therapy is often necessary for the treatment of advanced-stage disease. Systemic therapy options have evolved in recent years with the approval of novel agents such as romidepsin, brentuximab vedotin, and mogamulizumab. These NCCN Guidelines Insights discuss the diagnosis and management of MF and SS (with a focus on systemic therapy).
