Question: In the United States, patients who enroll in chemotherapy trials seldom reflect the attributes of the general population with cancer, as they are often younger, more functional, and have less comorbidity. We compared survival following three chemotherapy regimens according to the setting in which care was delivered (ie, clinical trial vs usual care) to determine the generalizability of clinical trial results to unselected elderly Medicare patients.', 'Using SEER-Medicare data, we estimated survival for elderly patients (ie, age 65 years or older, n = 14097) with advanced pancreatic or lung cancer following receipt of one of three guideline-recommended first-line chemotherapy regimens. We compared their survival to that of similarly treated clinical trial enrollees, without age restrictions, with the same diagnosis and stage (n = 937). All statistical tests were two-sided.', 'Trial patients were 9.5 years younger than elderly Medicare patients. Medicare patients were more often white and tended to live in areas of greater educational attainment than trial enrollees. For each tumor type, Medicare patients who were 75 years or older had median survivals that were six to eight weeks shorter than those of trial patients (4.3 vs 5.8 months following treatment with single agent gemcitabine for advanced pancreatic cancer, P = .03; 7.3 vs 8.9 months following treatment with carboplatin and paclitaxel for stage IV non-small cell lung cancer, P = .91; 8.2 vs 10.2 months following treatment with CDDP/ VP16 for extensive stage small cell lung cancer, P ≤ .01), whereas younger Medicare patients had survival times that were similar to those of trial patients.

Question: Hepatocellular carcinoma (HCC) is one of the most common solid tumors and ranks the third leading cause of cancer mortality worldwide. The purpose of this study was to examine the expression dynamics of GOLPH3 in HCC tissue samples, and explore the correlation between GOLPH3 expression and prognosis in patients with HCC.', 'The levels of Golgi phosphoprotein 3 (GOLPH3) mRNA and protein in liver cancer cell lines and fresh tissues were determined by qRT-PCR and Western blotting. Additionally, the protein expression of GOLPH3 was detected by immunohistochemistry.', 'High GOLPH3 expression was positively correlated with serum AFP level (P=0.015) and tumor recurrence or metastasis (P=0.010). In addition, liver cancer patients with high GOLPH3 expression had significantly poorer overall survival (HR, 1.87; 95% CI, 1.19-2.94; P=0.006) and poorer disease-free survival (HR, 1.90; 95% CI, 1.21-2.98; P=0.005) than those with low GOLPH3 expression. The cumulative 5-year survival rate was only 35.19% (95% CI, 26.18%-44.20%) in the high GOLPH3 expression group, whereas it was 55.93% (95% CI, 43.26%-68.60%) in the low GOLPH3 expression group. Furthermore, multivariate Cox regression analysis demonstrated that the expression of GOLPH3, tumor size and tumor multiplicity were independent prognostic predictors for HCC patients.

Question: Sputum Gram stain and culture have been said to be unreliable indicators of the microbiological diagnosis of bacterial pneumonia. The etiological diagnosis of pneumonia is surrounded by great degree of uncertainty. This uncertainty should be and can be calculated and incorporated in the diagnosis and treatment.', 'To determine the diagnostic accuracy and diagnostic value of sputum Gram stain in etiological diagnosis and initial selection of antimicrobial therapy of bacterial community acquired pneumonia (CAP). DESIGN-METHOD: Prospective study of 1390 patients with CAP admitted January 2002-June 2008, to our institutions. Of the 1390 patients, 178 (12.8%) fulfilled the criteria for inclusion into this study (good-quality sputa and presence of the same microorganism in blood and sputum cultures which was used as gold standard for assessing the diagnostic accuracy and diagnostic value of sputum Gram stain).', 'The sensitivity of sputum Gram stain was 0.82 for Pneumococcal pneumonia, 0.76 for Staphylococcal pneumonia, 0.79 for Haemophilus influenzae pneumonia and 0.78 for Gram-negative bacilli pneumonia. The specificity of sputum Gram stain was 0.93 for Pneumococcal pneumonia, 0.96 for Staphylococcal pneumonia, 0.96 for H. influenzae pneumonia and 0.95 for Gram-negative bacilli pneumonia. The positive likelihood ratio (LR+) was 11.58 for Pneumococcal pneumonia, 19.38 for Staphylococcal pneumonia, 16.84 for H. influenzae pneumonia, 14.26 for Gram-negative bacilli pneumonia. The negative likelihood ratio (LR-) was 0.20 for Pneumococcal pneumonia, 0.25 for Staphylococcal pneumonia, 0.22 for H. influenzae pneumonia, and 0.23 for Gram-negative bacilli pneumonia.
