Primary large cell neuroendocrine carcinoma of the breast, a case report with an unusual clinical course.

Large cell neuroendocrine carcinoma of the breast (NECB) is an extremely rare type of breast cancer; little is known about effective chemotherapies, and data on pathologic response to treatment are unavailable. We report the case of a 34-years-old woman with large cell NECB with initial clinical and pathologic evidence of treatment response to anthracycline-containing neo-adjuvant therapy. Histologic reassessment early during anthracycline chemotherapy revealed cell death with necrosis of 50% of the tumor cells seen in the biopsy specimen.

Phase 1/2 study of everolimus in advanced hepatocellular carcinoma.

Background: The phosphoinositide 3-kinase/Akt/mammalian target of rapamycin pathway plays a critical role in the pathogenesis of hepatocellular carcinoma (HCC). We performed a single-arm, phase 1/2 study of everolimus in patients with advanced HCC.

Methods: Patients with histologically confirmed measurable advanced HCC, 0-2 prior regimens, and adequate hematologic, hepatic, and renal functions received everolimus at 5 mg/day or 10 mg/day orally (6 weeks/cycle).
