High expression of dihydropyrimidine dehydrogenase in lung adenocarcinoma is associated with mutations in epidermal growth factor receptor: implications for the treatment of non--small-cell lung cancer using 5-fluorouracil.
It has been shown that 5-fluorouracil (5-FU) sensitivity in patients with non-small-cell lung cancer (NSCLC) is associated with epidermal growth factor receptor (EGFR) mutation status. However, the relationship between dihydropyrimidine dehydrogenase (DPD), a 5-FU degrading enzyme, and EGFR mutation status is unknown. Here, we focus on clinicopathologic factors and in vitro correlations between DPD expression and EGFR mutation status. ⋯ High DPD expression was shown to be correlated with EGFR mutation in adenocarcinoma cells and tissues. Clinicians should take this finding into consideration when using 5-FU to treat patients with NSCLC.

Clinical TrialStage migration in planning PET/CT scans in patients due to receive radiotherapy for non-small-cell lung cancer.
This study examined rates of tumor progression in treatment-naive patients with non-small-cell lung cancer (NSCLC) as determined by repeat treatment-planning fluorine-18 ((18)F) fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT). ⋯ Radiation treatment planning with hybrid PET/CT scans repeated within 120 days of an initial staging PET/CT scan identified significant upstaging in more than half of patients. For a subset of patients who underwent both scans on the same instrument, SUV velocity predicts upstaging, and the difference between those upstaged and those not was statistically significant.

Clinical outcome with platinum-based chemotherapy in patients with advanced nonsquamous EGFR wild-type non-small-cell lung cancer segregated according to KRAS mutation status.
We hypothesized that KRAS mutations function as a marker of poor sensitivity to first-line platinum-based chemotherapy in patients with advanced nonsquamous EGFR wild-type (WT) non-small-cell lung cancer (NSCLC). ⋯ KRAS mutation appears to negatively affect sensitivity to first-line platinum-based chemotherapy in patients with advanced nonsquamous EGFR WT NSCLC. Studies on larger case series are needed to address differences in clinical outcome according to the type of mutation.

Interdisciplinary palliative care intervention in metastatic non-small-cell lung cancer.
Challenges and barriers continue to hinder the integration of palliative care models into comprehensive, ambulatory oncology care. This article aims to describe how symptoms, distress, and quality of life (QOL) data from the usual care phase of a National Cancer Institute-supported Program Project informed the development of an interdisciplinary, tailored palliative care intervention for patients with metastatic non-small-cell lung cancer (NSCLC). ⋯ Patients with metastatic NSCLC continue to experience high symptom burden and diminished physical well-being over time while receiving cancer treatments. An interdisciplinary palliative care intervention is currently being tested to improve symptom burden and overall QOL.

Influence of medical comorbidities on the presentation and outcomes of stage I-III non-small-cell lung cancer.
Non-small-cell lung cancer presentation, treatment, and outcomes vary widely according to socioeconomic factors and other patient characteristics. To determine whether medical comorbidities account for these observations, we incorporated a validated medical comorbidity index into an analysis of patients diagnosed with stage I to III NSCLC. ⋯ In this cohort of patients with stage I to III NSCLC, increasing comorbidity burden had a nonsignificant association with diagnosis at earlier disease stage. Although comorbidity burden was significantly associated with outcome for early stage and locally advanced disease, it did not account for survival differences based on multiple other patient and disease characteristics.
