Performance of a prognostic 31-gene expression profile in an independent cohort of 523 cutaneous melanoma patients.

Background: The heterogeneous behavior of patients with melanoma makes prognostication challenging. To address this, a gene expression profile (GEP) test to predict metastatic risk was previously developed. This study evaluates the GEP's prognostic accuracy in an independent cohort of cutaneous melanoma patients.

Pandemic-related health behavior: repeat episodes of influenza-like illness related to the 2009 H1N1 influenza pandemic.

The Houston Health Department (HHD) in Texas tracks influenza-like illness (ILI) in the community through its Influenza Sentinel Surveillance Program, which began in 2008. After the influenza A(H1N1) pandemic (pH1N1) in 2009, investigators sought to assess the feasibility of this program as a non-traditional data source for tracking and monitoring care-seeking activities. Through the process of characterizing and describing patients who had 'return visits', or who were considered the heaviest ILI-related care-utilizers, the investigators sought to understand the strengths and limitations of this data source.

Endometrial Cancer Associated Symptoms: A Case-Control Study.

Background: The majority of women with endometrial cancer (EC) present at an early stage with an associated 5-year survival rate of >90%. High rates of early detection are attributed to warning symptoms; however, the prevalence of such symptoms has not been well defined.

Methods: A case-control study was conducted assessing the prevalence of symptoms in EC patients at a large cancer center compared with healthy controls.

Releasing test results directly to patients: A multisite survey of physician perspectives.

Objective: To determine physician perspectives about direct notification of normal and abnormal test results.

Methods: We conducted a cross-sectional survey at five clinical sites in the US and Australia. The US-based study was conducted via web-based survey of primary care physicians and specialists between July and October 2012.

Gene expression profiling for molecular staging of cutaneous melanoma in patients undergoing sentinel lymph node biopsy.

Background: A gene expression profile (GEP) test able to accurately identify risk of metastasis for patients with cutaneous melanoma has been clinically validated.

Objective: We aimed for assessment of the prognostic accuracy of GEP and sentinel lymph node biopsy (SLNB) tests, independently and in combination, in a multicenter cohort of 217 patients.

Methods: Reverse transcription polymerase chain reaction (RT-PCR) was performed to assess the expression of 31 genes from primary melanoma tumors, and SLNB outcome was determined from clinical data.
