Abstract

Purpose

The primary objective of this study was to identify the potential predictors to assess the impact of maintenance therapy after induction immunochemotherapy in the real-world setting of patients with advanced non-small cell lung cancer (NSCLC).

Methods

We retrospectively identified 152 patients with advanced NSCLC who received immunochemotherapy at 8 hospitals in Japan between January 2019 and December 2019. Patients who received at least four cycles of induction immunochemotherapy and one cycle of maintenance therapy with immune checkpoint inhibitors were included. We investigated the biomarkers for progression-free survival (PFS) for maintenance therapy after induction immunochemotherapy.

Results

Out of the 92 patients with advanced NSCLC included in the study, 42 received maintenance therapy with cytotoxic agents, whereas 50 received maintenance therapy without cytotoxic agents. Among those who received maintenance therapy without cytotoxic agents, responders to prior immunochemotherapy had significantly longer PFS than non-responders (p = 0.004), except those with maintenance therapy with cytotoxic agents. In non-responders to prior immunochemotherapy, patients with maintenance therapy with cytotoxic agents had significantly longer PFS than those with maintenance therapy without cytotoxic agents (log-rank p = 0.007), whereas, among responders to prior immunochemotherapy, there was no significant difference in PFS for different maintenance regimens (log-rank p = 0.31).

Conclusions

This retrospective study showed that response to prior immunochemotherapy was associated with clinical outcomes among patients with advanced NSCLC who received maintenance therapy.

Neu im Fachgebiet Onkologie

Studie zur HIFU bei Prostatakrebs lässt viele Fragen offen

Führt eine HIFU-Ablation beim Prostatakarzinom im Vergleich mit einer radikalen Prostatektomie zu ähnlichen onkologischen, aber besseren funktionalen Ergebnissen? Interimsdaten der französischen HIFI-Studie sind uneindeutig. In einem Kommentar zur Studie werden zumindest drei allgemeine Erkenntnisse herausgearbeitet.

Bei Achalasie auf Candidiasis der Speiseröhre achten!

Bei Achalasie-Betroffenen sollte man immer auch auf Candida-Infektionen achten, warnen Forschende aus Rotterdam. In ihrer Studie ließ die Pilzinfektion das Risiko für ein Ösophaguskarzinom massiv steigen.

Adipositas als negativer Prognosefaktor bei Kindern mit Krebs

Eine kanadische Studie weist darauf hin, dass Übergewicht zum Zeitpunkt der Krebsdiagnose ein unabhängiger Risikofaktor für schlechtere Überlebenschancen bei erkrankten Kindern und Jugendlichen sein könnte. Allerdings sind nicht alle Patientinnen und Patienten gleichermaßen betroffen.


Polypen bei nahen Verwandten – erhöhtes Darmkrebsrisiko

Werden bei erstgradigen Verwandten gutartige Darmpolypen identifiziert, ist das Risiko, selbst an einem Kolorektalkarzinom zu erkranken, deutlich erhöht – vor allem das für eine früh beginnende Erkrankung. Hier könnte sich eine frühe Koloskopie besonders lohnen.
