Dr. Anjan Patel's Thoughts
Throwback by JCO! Docetaxel vs Pemetrexed in 2L NSCLC showed similar OS/PFS outcomes, but Pemetrexed was tolerated better particularly in terms of myelosuppression. Pemetrexed was active in squamous cancers as well.
PURPOSE
To compare the efficacy and toxicity of pemetrexed versus docetaxel in patients with advanced non-small-cell lung cancer (NSCLC) previously treated with chemotherapy.
PATIENTS AND METHODS
Eligible patients had a performance status 0 to 2, previous treatment with one prior chemotherapy regimen for advanced NSCLC, and adequate organ function. Patients received pemetrexed 500 mg/m2 intravenously (IV) day 1 with vitamin B12, folic acid, and dexamethasone or docetaxel 75 mg/m2 IV day 1 with dexamethasone every 21 days. The primary end point was overall survival.
RESULTS
Five hundred seventy-one patients were randomly assigned. Overall response rates were 9.1% and 8.8% (analysis of variance P = .105) for pemetrexed and docetaxel, respectively. Median progression-free survival was 2.9 months for each arm, and median survival time was 8.3 versus 7.9 months (P = not significant) for pemetrexed and docetaxel, respectively. The 1-year survival rate for each arm was 29.7%. Patients receiving docetaxel were more likely to have grade 3 or 4 neutropenia (40.2% v 5.3%; P < .001), febrile neutropenia (12.7% v 1.9%; P < .001), neutropenia with infections (3.3% v 0.0%; P = .004), hospitalizations for neutropenic fever (13.4% v 1.5%; P < .001), hospitalizations due to other drug related adverse events (10.5% v 6.4%; P = .092), use of granulocyte colony-stimulating factor support (19.2% v 2.6%, P < .001) and all grade alopecia (37.7% v 6.4%; P < .001) compared with patients receiving pemetrexed.
CONCLUSION
Treatment with pemetrexed resulted in clinically equivalent efficacy outcomes, but with significantly fewer side effects compared with docetaxel in the second-line treatment of patients with advanced NSCLC and should be considered a standard treatment option for second-line NSCLC when available.

Perioperative Nivolumab and Chemotherapy in Stage III Non–Small-Cell Lung Cancer
The NADIM-II study looked at perioperative Nivo+chemo vs. chemo alone in stIIIA – stIIIB NSCLC. High pCR rates with chemoIO are again seen, as in the Checkmate 816 and NADIM-I study, they were even higher in this cohort (37%), suggesting higher-stage patients derive the biggest benefit from neoadjuvant chemoIO. Pretty impressive results, however, I still must point out that this was a phase II study with a small sample size, OS benefits have not been demonstrated and this has yet to make it on to NCCN.
