In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

[Q]: Context: We studied the weight of decision-making on clinical assessment of melanocytic lesions judging benign, atypical, and malignant lesions; common mistakes; and total removal rates, comparing dermatologists with nondermatologists.', 'Of 11,246 histopathology specimens, 3,768 had a clinical assessment of melanocytic lesions. Histopathologic diagnosis served as the gold standard.', 'Benign nevi were assessed most accurately (77%). Dermatologists assessed benign nevi better (p < .0001). The accuracy of clinical assessment in atypical nevi and melanoma was lower (23% and 42%, respectively). Seborrheic keratosis was the most common mistaken diagnosis. Complete removal of clinically benign nevi, atypical nevi, and melanoma was 84%, 90%, and 89%. Decision-making impaired clinical assessement of melanocytic lesions by 5% for dermatologists and 9% for nondermatologists.\Question: Does weight of decision-making impair clinical assessment of melanocytic lesions?
[A]: The accuracy of clinical assessment of melanocytic lesions is high for benign nevi, with dermatologists outperforming nondermatologists. Clinicians overestimated malignant potential. Complete removal was more frequent in suspicious lesions. Clinical decision-making impaired assessment by 5 to 9%.


[Q]: Context: Endothelial Microparticles (EMP) are small fragments of endothelial cell membrane shed during apoptosis or activation. Our group has previously reported elevations of EMP in patients with coronary artery disease (CAD), thrombotic thrombocytopenic purpura (TTP), pre-eclampsia, multiple sclerosis (MS), and severe hypertension (HTN). In the present study, we evaluate the possible relationship between EMP levels and the angiographic severity and characteristics of coronary obstructive lesions.', 'We studied a total of 43 patients undergoing coronary angiography. Fifteen had presented with acute myocardial infarction (MI), 20 with unstable anginas (UA), 5 with stable angina (SA) and 3 with congestive heart failure. Coronary angiography was reviewed and coronary lesions were classified using the Ambrose classification. Coronary stenoses were classified as high and low risk. High-risk included lesions with eccentric appearance (type II), presence of thrombi, or multiple irregularities. Low-risk lesions were defined as concentric or type I. Lesions were also analyzed by degree of stenosis and history of acute coronary syndrome (ACS). EMP in plasma was assayed by flow cytometry.', 'EMP in eccentric type II or multiple irregular lesions (high-risk) were 2.5-fold higher than in type I or concentric (low-risk) lesions, p<0.05. Lesions with thrombi had three-fold higher EMP than those without (p=0.05). Mild stenosis (>20%-<45%) had three-fold higher EMP than more severe (>45%), and five-fold higher than those without stenosis (p<0.01). Among patients with type II lesions, those with first ACS episode had four-fold higher EMP levels than those with recurrent ACS (p<0.01).\Question: Do endothelial microparticles correlate with high-risk angiographic lesions in acute coronary syndromes?
[A]: High EMP was associated with high-risk angiographic lesions including eccentric type II, multiple irregular, and lesions with thrombi. Mild to moderate stenosis was associated with higher EMP levels than severe stenosis. EMP may be a useful marker in detecting endothelial injury and risk of ACS as defined by angiography.


[Q]: Context: Lung adenocarcinomas with mutations in the epidermal growth factor receptor (EGFR) have unprecedented initial responses to targeted therapy against the EGFR. Over time, however, these tumors invariably develop resistance to these drugs. We set out to investigate alternative treatment approaches for these tumors.', 'To investigate the immunologic underpinnings of EGFR mutant lung adenocarcinoma, we utilized a bi-transgenic mouse model in which a mutant human EGFR gene is selectively expressed in the lungs.', 'EGFR oncogene-dependent progression and remission of lung adenocarcinoma was respectively dependent upon the expansion and contraction of alveolar macrophages, and the mechanism underlying macrophage expansion was local proliferation. In tumor-bearing mice, alveolar macrophages downregulated surface expression of MHC-II and costimulatory molecules; increased production of CXCL1, CXCL2, IL-1RA; and increased phagocytosis. Depletion of alveolar macrophages in tumor-bearing mice resulted in reduction of tumor burden, indicating a critical role for these cells in the development of EGFR mutant adenocarcinoma. Treatment of mice with EGFR targeting clinical drugs (erlotinib and cetuximab) resulted in a significant decrease in alveolar macrophages in these mice. An activated alveolar macrophage mRNA signature was dominant in human EGFR mutant lung adenocarcinomas, and the presence of this alveolar macrophage activation signature was associated with unfavorable survival among patients undergoing resection for EGFR mutant lung adenocarcinoma.\Question: Is progression of EGFR mutant lung adenocarcinoma driven by alveolar macrophages?
[A]:
Because of the inevitability of failure of targeted therapy in EGFR mutant NSCLC, these data suggest that therapeutic strategies targeting alveolar macrophages in EGFR mutant NSCLC have the potential to mitigate progression and survival in this disease.
