High-dose erlotinib for refractory leptomeningeal metastases after failure of standard-dose EGFR-TKIs

Abstract: High-dose erlotinib suggested its efficacy and safety in some patients with refractory LM. It represents a potential therapeutic option against LM after failure of standard-dose EGFR-TKIs, especially to palliate LM-related neurological symptoms.

“…92,93 However, CSF concentrations may reach therapeutic levels at high doses. 92 Although there have been no randomized trials, responses have been described to erlotinib [94][95][96][97][98][99][100][101][102] and gefitinib, 103,104 particularly at high doses. Several retrospective studies have reported prolonged survival in EGFR-mutant patients who had NSCLC with LM treated with firstgeneration EGFR TKIs.…”

“…28 However, conventional doses of erlotinib have a moderate effect on the control of brain metastasis, and some scholars have proposed high-dose pulse administration. 11 A phase II study showed that the ORR was 74% and median PFS was 10 months with brain metastasis patients taking pulse-continuous dose erlotinib. 29 However, high-dosage of erlotinib will cause more serious side effects and economic effects, so it is not widely used in clinical practice.…”

“…10 Consequently, there are emerging reports indicating high-dose EGFR-TKI could increase the concentration in CSF for EGFR=mutated patients with LM, especially in patients' CNS progression after taking standard-dose EGFR-TKI. 11,12 Highdosage erlotinib did improve the control rate of LM, but it was associated with a serious rash reaction and/or diarrhea, and thus it was not recommended. 13,14 Osimertinib, the third-generation TKI, has stronger central activity than the first generation.…”

“…Nachdem die GefitinibDosis von 500 auf 750 mg und dann auf 1000 mg täglich gesteigert wurde, zeigte ein Patient, der auf die vorherige Standarddosis Gefitinib nicht angesprochen hatte, eine erhebliche Verbesserung seiner Kopfschmerz-und Tremorsymptome sowie radiographisches und zytologisches Ansprechen [8]. Dramatische therapeutische Effekte von Erlotinib bei Patienten mit LC ohne Ansprechen auf die Standarddosis waren außerdem unter folgenden ErlotinibDosisschemata zu verzeichnen: 600 mg alle 4 Tage [9], 450 mg alle 3 Tage [10] sowie 1500 mg einmal wöchentlich [11,12]. Zwar bescheinigt eine kombinierte Subgruppenanalyse zweier randomisierter Studien ein besseres progressionsbezogenes Überleben unter Afatinib als systemischer Standard-Chemotherapie in der Erstlinientherapie von Hirnmetastasen bei NSCLC mit häufigen EGFR-Genmutationen [13] …”
