Abstract
Background and purpose: Tumour infiltrating lymphocytes (TIL), tumour associated macrophages (TAM) and PD-L1/PD-1 expression play a key role in anticancer immunosurveillance. We studied their influence on response to neoadjuvant radiochemotherapy (RCT) and prognosis in patients with oesophageal adenocarcinoma (OAC). Materials and methods: Between 10/2004 and 06/2018, pre-RCT biopsy-specimens were available from 76 patients with locally advanced, non-metastatic OAC scheduled for trimodality therapy. We evaluated intra- and peritumoural expression of FoxP3+, CD8+, CD68+, CD163+, and PD-L1/PD-1 to determine their influence on tumour regression grade (TRG) and survival. Results: Poor tumour regression was detected for cN+ (RR 0.77 [95% CI 0.66-0.90], p=0.001), low intratumoural FoxP3+/CD8+ ratio (RR 0.75 [0.60-0.96], p=0.020), high peritumoural CD163+/CD68+ ratio (RR 0.77 [0.60-0.99], p=0.045), high intratumoural TAM density (RD - 0.44 [-0.82 to -0.06], p=0.023), and negative peritumoural PD-L1 expression (RR 0.75 [0.57- 0.98], p=0.036). Apart from poor resection quality and TRG, pretherapeutic high peritumoural CD8+ infiltration (HR 2.36 [1.21-4.61], p=0.012), short intratumoural FoxP3+ to CD8+ cell-to-cell distances in middle ranged CD8+ density (HR 2.55 [1.00-6.52], p=0.050), positive intratumoural PD-1 expression (HR 1.92 [1.08-3.45], p=0.038), and low intratumoural CD8+ density combined with positive PD-L1 expression (HR 3.13 [1.12-8.33], p=0.042) were significant unfavourable prognostic factors in multivariate analysis. Conclusions: The evaluated immunologic parameters showed independent predictive and prognostic value in patients with OAC.
Abstract (croatian)
Pozadina i svrha: Tumor infiltrišući limfociti (TIL), tumor asocirani makrofagi (TAM) i PDL1/PD-1 ekspresija igra ključnu ulogu u antikancerskom imunološkom nadzoru. Mi smo proučavali njihov uticaj na odgovor na neoadjuvantnu radiohemoterapiju (RCT) i prognozu kod pacijenata sa adenokarcinomima ezofagusa (OAC). Materijali i metode: Između 10/2004 i 06/2018, uradjena je pre-RCT biopsija-uzoraka od ukupno 76 pacijenata sa lokalno uznapredovalim, ne metastatskim OAC pripremanih za trimodalnu terapiju. Procenjivali smo intra- i peritumoralnu ekspresiju FoxP3+, CD8+, CD68+, CD163+ i PD-L1/PD-1 da bi utvrdili njihov uticaj na stepen tumorske regresije (TRG) i preživljavanje. Rezultati: Slaba tumorska regresija je uočena kod cN+ (RR 0.77 [95% CI 0.66-0.90], p=0.001), nizak intratumorski FoxP3+/CD8+ racio (RR 0.75 [0.60-0.96], p=0.020), visok peritumorski CD163+/CD68+ racio (RR 0.77 [0.60-0.99], p=0.045), visoka intratumorska gustina TAM (RD -0.44 [-0.82 to -0.06], p=0.023), i negativna peritumorska PD-L1 ekspresija (RR 0.75 [0.57- 0.98], p=0.036). Nezavisno od slabog resekcionog kvaliteta i TRG, preterapijska visoka peritumoralna CD8+ infiltracija (HR 2.36 [1.21-4.61], p=0.012), kratke intratumorske FoxP3+ do CD8+ udaljenosti ćelije od ćelije kod srednje CD8+ intratumorske gustine (HR 2.55 [1.00-6.52], p=0.050), pozitivna intratumorska PD-1 ekspresija (HR 1.92 [1.08-3.45], p=0.038), i niska intratumorska CD8+ gustina u kombinacija sa pozitivnom PD-L1 ekspresijom (HR 3.13 [1.12-8.33], p=0.042) bili su značajno nepovoljni prognostički faktori u multivarijantnoj analizi. Zaključci: Procenjivani imunološki parametri pokazali su nezavisnu prediktivnu i prognostičku vrednost kod pacijenata sa adenokarcinomima ezofagusa.
