General Oncology - Survival Differences After Docetaxel, Erlotinib are EGFR Dependent

General Oncology - Survival Differences After Docetaxel, Erlotinib are EGFR Dependent | Lung Cancer Dispatch | Scoop.it

"Results from the DELTA trial indicate no significant differences in progression-free (PF) or overall survival (OS) after treatment with docetaxel versus erlotinib in non-small-cell lung cancer (NSCLC) patients unselected for their epidermal growth factor receptor (EGFR) mutation status.


"By contrast, in the subgroup of patients whose tumours were positive for EGFR mutations, PFS and OS were nonsignificantly longer in the erlotinib than the docetaxel group, whereas in those with wild-type tumours, docetaxel was significantly superior to erlotinib in terms of PFS, observe the researchers in the Journal of Clinical Oncology."


Editor's note: This story discusses the results of a clinical trial comparing the targeted drug erlotinib (aka Tarceva) with the chemotherapy drug docetaxel in volunteer patients with non-small cell lung cancer (NSCLC). In the trial, patients whose tumors had mutations in the EGFR gene benefitted more from erlotinib than docetaxel, while patients without EGFR mutations (as detected by molecular testing) had better results from docetaxel.

ASCO: Targeted Tx Combo Stalls NSCLC

ASCO: Targeted Tx Combo Stalls NSCLC | Lung Cancer Dispatch | Scoop.it

"Adding bevacizumab (Avastin) to first-line targeted therapy delayed progression in a subgroup of non-small cell lung cancer (NSCLC), an open-label trial showed.


"Progression-free survival was 46% better with bevacizumab plus erlotinib (Tarceva), at 16.0 months compared with 9.7 on erlotinib alone in an EGFR mutation-positive population (P=0.0015), Terufumi Kato, MD, of Kanagawa Cardiovascular and Respiratory Center in Yokohama, Japan, and colleagues found."


Editor's note: A combination of two targeted therapy drugs has shown promise for treating some patients with non-small cell lung cancer (NSCLC). The two drugs are called bevacizumab (brand name Avastin) and erlotinib (brand name Tarceva). The research described in this story found that the combination works better for patients whose tumors have mutations in the EGFR gene (as detected by molecular testing) than erlotinib alone.

Thoracic RT Yields Improved Survival in Extensive-Stage SCLC

Thoracic RT Yields Improved Survival in Extensive-Stage SCLC | Lung Cancer Dispatch | Scoop.it

"Thoracic radiotherapy along with prophylactic cranial irradiation (PCI) significantly prolonged progression-free and overall survival in patients with extensive-stage small-cell lung cancer, according to results of a new study presented at ASCO.


"Ben Slotman, MD, PhD, of VU University Medical Center in Amsterdam, presented the study and said that previous work had shown that PCI could improve both symptomatic brain metastases and overall survival at 1 year. 'In that study, we also noticed that the vast majority of patients after chemotherapy had intrathoracic disease' and intrathoracic progression, he said, which was the impetus for the new study using thoracic radiotherapy."


Editor's note: To learn more about new prospects for treating small cell lung cancer (SCLC), see our two-part blog feature on the topic.

Chemotherapy May be Better for Certain Patients with Advanced Lung Cancer

Chemotherapy May be Better for Certain Patients with Advanced Lung Cancer | Lung Cancer Dispatch | Scoop.it

"Among patients with advanced non-small cell lung cancer without a mutation of a certain gene, conventional chemotherapy, compared with treatment using epidermal growth factor receptor tyrosine kinase inhibitors, was associated with improvement in survival without progression of the cancer, but not with overall survival, according to a study."


Editor's note: The drugs discussed in this story, "epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors," are targeted therapies that are used to treat lung cancer patients whose tumors have mutations in the EGFR gene, as detected by molecular testing. Scientists wanted to find out whether the drugs could also help patients without EGFR mutations. However, it was found that the drugs were no more effective than chemotherapy in improving patients' overall survival. This supports the idea that EGFR inhibitor drugs should only be given to patients whose tumors have EGFR mutations.
