Phase 2 study evaluating the combination of sorafenib and temsirolimus in the treatment of radioactive iodine-refractory thyroid cancer.

Background: Patients with recurrent and/or metastatic, radioactive iodine-refractory thyroid carcinoma have limited treatment options. Sorafenib, an oral kinase inhibitor, is approved by the US Food and Drug Administration for the treatment of radioactive iodine-refractory thyroid carcinoma, although it demonstrated low response rates (12.2%) as a single agent in the first-line setting.

A phase I trial of the Hedgehog inhibitor, sonidegib (LDE225), in combination with etoposide and cisplatin for the initial treatment of extensive stage small cell lung cancer.

Objectives: The Hedgehog pathway has been implicated in small cell lung cancer (SCLC) tumor initiation and progression. Pharmacologic blockade of the key Hedgehog regulator, Smoothened, may inhibit these processes. We performed a phase I study to determine the maximum tolerated dose (MTD) of sonidegib (LDE225), a selective, oral Smoothened antagonist, in combination with etoposide/cisplatin in newly diagnosed patients with extensive stage SCLC.

Impact of proposed IASLC/ATS/ERS classification of lung adenocarcinoma: prognostic subgroups and implications for further revision of staging based on analysis of 514 stage I cases.

A new lung adenocarcinoma classification is being proposed by the International Association for the Study of Lung Cancer, American Thoracic Society and European Respiratory Society (IASLC/ATS/ERS). This proposal has not yet been tested in clinical datasets to determine whether it defines prognostically significant subgroups of lung adenocarcinoma. In all, 514 patients who had pathological stage I adenocarcinoma of the lung classified according to the Union for International Cancer Control/American Joint Committee on Cancer 7th Edition, and who had undergone a lobectomy with mediastinal lymph node dissection were retrospectively reviewed.

Analytical strategies for characterizing chemotherapy diffusion with patient-level population-based data.

To inform assessments of the quality of cancer care, we describe analytical approaches to characterizing trends in diffusion of chemotherapy drugs subsequent to their US FDA approval. The economics and medical literature provide two distinct sets of empirical methods for investigating diffusion of innovations: aggregate models, which use the level of market penetration as an estimator of diffusion; and disaggregate models, which evaluate diffusion based on the time required for different individual units to adopt innovations. When patient-level population-based data are available, disaggregate methods make the best use of the available information.
