Temsirolimus, an mTOR inhibitor for treatment of patients with advanced renal cell carcinoma.

Temsirolimus is a targeted therapy that inhibits mammalian target of rapamycin (mTOR), a central regulator of tumor cell responses to growth stimuli. Temsirolimus has a broad anticancer activity profile that impacts tumor cell growth, proliferation, and survival through its specific inhibition of mTOR. In a randomized phase III trial that enrolled previously untreated patients with advanced renal cell carcinoma (RCC) and poor prognostic features, temsirolimus significantly prolonged overall survival compared with interferon-alpha, a standard therapy (p = 0.

Postchemotherapy MRI overestimates residual disease compared with histopathology in responders to neoadjuvant therapy for locally advanced breast cancer.

Unlabelled: The utility of breast magnetic resonance imaging in patients receiving neoadjuvant chemotherapy is not well defined. We compared serial magnetic resonance imaging examinations with histologic posttreatment examinations in patients treated with primary chemotherapy for locally advanced breast cancer.

Patients And Methods: Eligible patients with locally advanced breast cancer received doxorubicin 60 mg/m(2) and docetaxel 60 mg/m(2) (with granulocyte colony stimulating factor support) every 14 days for a maximum of six cycles.

Five-year update of an expanded phase II study of dose-dense and -intense doxorubicin, paclitaxel and cyclophosphamide (ATC) in high-risk breast cancer.

Objectives: This study evaluated the safety and efficacy of dose-dense and -intense sequential doxorubicin (A), paclitaxel (T) and cyclophosphamide (C) as adjuvant therapy for breast cancer (BC) with >or=4 ipsilateral axillary lymph nodes.

Methods: Patients were recruited after BC surgery if >or=4 axillary nodes were involved by metastatic cancer. Planned treatment was A 90 mg/m(2) three times every 14 days (q14d x 3), T 250 mg/m(2) q14d x 3 and C 3 g/m(2) q14d x 3 combined with filgrastim support.
