Inflammatory breast cancer: early recognition and diagnosis is critical.

Inflammatory breast cancer is a rare and aggressive malignancy that is often initially misdiagnosed because of its similar presentation to more benign breast pathologies such as mastitis, resulting in treatment delays. Presenting symptoms of inflammatory breast cancer include erythema, skin changes such as peau d' orange or nipple inversion, edema, and warmth of the affected breast. The average age at diagnosis is younger than in noninflammatory breast cancer cases. Known risk factors include African American race and obesity. Diagnostic criteria include erythema occupying at least one-third of the breast, edema, peau d' orange, and/or warmth, with or without an underlying mass; a rapid onset of <3 months; and pathologic confirmation of invasive carcinoma. Treatment of inflammatory breast cancer includes trimodal therapy with chemotherapy, surgery, and radiation. An aggressive surgical approach that includes a modified radical mastectomy enhances survival outcomes. Although the outcomes for patients with inflammatory breast cancer are poor compared with those of patients with noninflammatory breast cancer, patients with inflammatory breast cancer who complete trimodal therapy have a favorable locoregional control rate, underscoring the importance of a prompt diagnosis of this serious but treatable disease. Obstetrician-gynecologists and other primary care providers must recognize the signs and symptoms of inflammatory breast cancer to make a timely diagnosis and referral for specialized care.

Clinical features and response to systemic therapy in a historical cohort of advanced or unresectable mucosal melanoma.

There are very few data available regarding the pattern of first metastases in resected mucosal melanomas (MMs) as well as the response of advanced MM to cytotoxic therapy. A retrospective, single-institution cohort was assembled of all patients with advanced/unresectable MM between 1995 and 2012 who had received systemic therapy with available imaging (N=81). Responses to first-line and second-line systemic therapy were assessed using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. The relationship between response, overall survival, and clinical covariates was investigated using Cox proportional hazards regression. Primary sites included anorectal (N=31, 38%), vulvovaginal (N=28, 35%), head and neck (N=21, 26%), and gallbladder (N=1, 1%) mucosa. Seven percent of patients had their first relapse in the brain. Cytotoxic therapy represented 82 and 51% of first-line and second-line regimens. The best response achieved in the first-line setting was similar for single-agent [10%; 95% confidence interval (CI): 1-32%] and combination alkylator therapy (8%; 95% CI: 2-21%). Median overall survival from first-line treatment was 10.3 months (95% CI: 8.7-13.9 months). Patients with elevated lactic dehydrogenase [hazard ratio (HR): 1.87, 95% CI: 1.10-3.19, P=0.020] and Eastern Cooperative Oncology Group performance status 1-2 (HR: 1.69, 95% CI: 1.05-2.72, P=0.030) had a higher risk of death, whereas patients with 12-week objective responses had a lower risk of death (HR: 0.12, 95% CI: 0.04-0.41, P<0.001). Cytotoxic systemic therapy has modest activity in advanced/unresectable MM, belying its adjuvant benefit. Patients whose tumors have an objective response to therapy have a lower probability of death. Brain imaging should be considered in routine surveillance.
