Lung Cancer

How long ago did we learn that smoking caused lung cancer? The USPSTF is poised to recommend annual screening CT scans for the detection of lung cancer in high risk individuals. Are there enough CT scanners to handle the volume? The LLC’s are forming now to put a dedicated lung screening CT machine next to every convenience store. Get your carton and CT in one stop!

Bench and mouse studies have shown that the Notch1 gene is a crucial contributor to tumorigenesis in non-small-cell lung cancer (NSCLC). It aids tumor initiation by suppressing apoptosis, or programmed cell death, which is regulated by p53.

A randomized phase III trial of adjuvant gefitinib in patients with completely resected non–small-cell lung cancer (NSCLC) was closed early, but available results suggest that the drug is unlikely to benefit this group of patients.

Among non–small-cell lung carcinoma (NSCLC) patients, foreign-born Hispanics show less cancer-related mortality compared with US-born Hispanics and non-Hispanic whites, in part due to social and cultural environment, according to results of a new study.

Identification of a significant micropapillary component within lung adenocarcinomas predicts a higher risk of relapse following lung-sparing surgery, according to results of a new study.

Based largely on evidence from the NLST, the USPSTF recently issued a draft recommendation for annual lung cancer screening using low-dose CT in high-risk individuals.

Results from the National Lung Screening Trial showed that screening for lung cancer with low-dose computed tomography yielded the most benefit among individuals who were at highest risk for cancer and less benefit in lower risk people.

The ALK-inhibitor crizotinib leads to longer progression-free survival than chemotherapy in patients with advanced ALK-positive non-small-cell lung cancer (NSCLC), according to results of a phase III clinical trial.

An assay system for gene expression analysis of paraffin-embedded patient samples is predictive of lung cancer histologic type, according to results published in the Journal of Molecular Diagnostics.

Two new studies show that afatinib, an orally bioavailable ERBB family blocker, could be effective in patients with non–small-cell lung cancer (NSCLC) who progressed on other therapies and in patients with advanced lung adenocarcinomas and EGFR mutations.

The FDA approved afatinib (Gilotrif) as a first-line therapy for patients with metastatic non-small-cell lung cancer whose tumors harbor certain mutations in the epidermal growth factor receptor gene.

A study including 17 cohorts with a total of more than 300,000 individuals found that ambient air pollution of various types contributes to lung cancer incidence across nine European countries.

A pair of studies from the ASCO annual meeting examined bone metastases from lung cancer, with one study finding that survival in patients was poorer in patients with bone metastases, and another study finding that the development of bone metastases could predict subsequent development of metastasis in the brain.

Researchers found that the more cost-effective option (surgery vs SBRT) in stage I lung cancer depends on whether the disease is clearly or marginally operable.

Interim results of a small phase II study found a relatively good response rate with dabrafenib in BRAF V600E mutation-positive stage IV non-small-cell lung cancer (NSCLC) patients. The results were presented at ASCO.

A randomized, phase II trial showed improved progression-free survival in small-cell lung cancer with maintenance sunitinib vs placebo following standard chemotherapy, according to results presented at the ASCO annual meeting in Chicago.

Today at the 2013 ASCO meeting, we are discussing targeted therapy strategies for lung cancer and for treating patients after resistance to these drugs.

A phase III study, presented at ASCO, comparing pemetrexed and carboplatin with paclitaxel, carboplatin, and bevacizumab failed to find a difference in a composite endpoint of progression-free survival and severe drug-related toxicities in patients with nonsquamous non–small-cell lung cancer.

A simple serum protein test can help guide treatment decisions between chemotherapy and erlotinib as second-line therapy for patients with non-small-cell lung cancer, according to results of a phase III study presented at ASCO.

Results from the GALAXY-1 trial showed that the novel second-generation heat shock protein 90 (HSP90) inhibitor ganetespib could potentially improve survival in patients with advanced-stage non–small-cell lung cancer.

Guiding treatment for non–small-cell lung cancer (NSCLC) using expression levels of the proteins RRM1 and ERCC1 led to no difference in either progression-free or overall survival, according to a study presented at the American Society of Clinical Oncology (ASCO) annual meeting.

A massive French database study shows that genetic tumor profiling in patients with non–small-cell lung cancer (NSCLC) is feasible, and is already helping physicians guide treatment in many patients, according to results presented at the American Society of Clinical Oncology annual meeting in Chicago.

A large study shows that middle-age men engaged in lots of cardiovascular exercise have a reduced risk of developing and dying from lung and colorectal cancer.

The FDA approved a label expansion for erlotinib (Tarceva), along with the cobas EGFR mutation diagnostic test, to include patients untreated metastatic NSCLC patients whose tumors have either a deletion in exon 19 or exon 21 (L858R) substitution mutations in the EGFR gene.

A number of drugs have been approved that result in significant tumor responses. While many of these new drugs are associated with improved clinical outcomes, much more work in this area is essential, as most patients have tumors without such molecular features.

If we are to provide new options for the large numbers of NSCLC patients with no actionable mutation, we must focus on identifying new mutations through tissue acquisition. In the meantime, these patients are ideal candidates for the large number of available immunotherapy trials.

This review will describe the well-known use of VEGF antibodies; the current uses of EGFR and ALK tyrosine kinase inhibitors; newer agents being used against MET, FGFR, and other intracellular targets; insights regarding the field of immunotherapy in lung cancer; and finally, newer developments in chemotherapy.

Expression of the beta-3 tubulin (ß3T) isoform was a negative prognostic factor in non–small-cell lung cancer (NSCLC) patients, but did not predict treatment response for either paclitaxel or tubulin-inhibiting chemotherapy with ixabepilone.

A new study shows that drugs targeting HER2 might provide good results in the rare non-small-cell lung cancer (NSCLC) patients with HER2 mutations.

Women with lung cancer who ate more soy prediagnosis appear to survive longer than patients who ate fewer soy-based foods, according to a new Chinese study.
