had complete responses. However, most of these patients developed recurrent disease within four months. As currently recommended, brentuximab vedotin is use initially to treat widespread systemic disease; a single chemotherapeutic drug rather than aggressive combination chemotherapy with CHOP or similar regimens is used to treat patients not responding to brentuximab verdotin; aggressive chemotherapy regimens are used to treat widespread nodal and/of visceral disease and disease which failed on other regiments; and, although there is little data supporting this, employ allogeneic bone marrow transplantation for patients with multiple relapses that have progressed on systemic therapy. Recurrences, regardless of treatment type, are common. pcALCL has an estimated five-year failure-free survival rate of 55 percent. Nonetheless, the disease has a 10-year overall survival rate of 90%. Typically leg involvement portends a worse prognosis: it has a five-year disease-specific survival rate of 76 percent compared with 96 percent for disease in other locations. Involvement of local nodes alone in patients with skin lesions does not seem to portend an adverse prognosis. Breast implant-associated anaplastic large-cell lymphoma Signs and symptoms BIA-ALCL is a complication of silicon-filled and saline-filled breast implants which develops 9 years to 10 years (median times) after surgical implantation. First described in 1997, it is estimated that the prevalence of BIA-ACLC in individuals with implants that have a textured surface is 1 in 30,000 while the risk of it is 70-fold lower in individuals who have a smooth surface implant or have no implant at all (i.e. in patients that have another type of ALCL). These relations strongly suggest that BIA-ACLC develops primarily if not exclusively in patients with textured implants. In all cases, however, many researchers suspect that BIA-ALCL is an under-recognized, misdiagnosed, and under-reported complication of breast implants. Two-thirds of individuals with BIA-ALCL present with swelling, discomfort, and/or (rarely) pain in the affected breast. This is due to the development of a tumor mass and/or swelling caused by an effusion (i.e. fluid) that accumulates between the breast implant surface and the fibrous capsule that has grown around it. The effusion fluid typically contains white blood cells, tumor cells, and high levels of protein. Besides or in addition to breast swelling, patients present with a breast mass in 30% present of cases, enlarged lymph nodes in the armpit or around the chest clavicle bones in 20% of cases, and/or in a small percentage of cases lesions in more distant tissues.
