Pemetrexed for Stage 4 Lung Cancer: 75 Real Stories

Stage IV ERBB2-Mutated Lung Adenocarcinoma With Brain Metastases and Multiple Targeted Therapies

Patient Info: Anonymized, female, Under 40 | Stage IV

Biomarkers: ERBB2 exon 20 insertion, exact sequence not specified. ERBB2 copy-number gain was identified during progression on afatinib.

Metastatic Site: brain, adrenal gland, liver

The final documented afatinib plus bevacizumab rechallenge produced a mixed response followed by liver progression after 3 months.

EGFR L858R-mutant Stage IV lung adenocarcinoma managed after gefitinib-induced lung injury

Patient Info: Anonymized, Male, 40s | Stage IV

Biomarkers: EGFR L858R mutation

Metastatic Site: liver, bone, hilar lymph nodes, mediastinal lymph…

Gefitinib produced early tumor shrinkage but was stopped for interstitial lung disease; subsequent carboplatin, pemetrexed, and bevacizumab produced a good response, while variceal bleeding was controlled with endoscopic treatment.

Stage IV lung adenocarcinoma with brain metastasis: partial remission after pemetrexed/cisplatin and AOSD-like paraneoplastic syndrome

Patient Info: Anonymized, Male, 50s | Stage IV

Biomarkers: No tumor molecular biomarkers reported. AOSD-like syndrome had high ferritin, inflammation markers, and RF/ANA negative.

Metastatic Site: brain

As of November 2011, pemetrexed/cisplatin produced partial remission of Stage IV lung adenocarcinoma and controlled the AOSD-like paraneoplastic syndrome without recurrent fever, rash, or arthralgia.
