P1.07-018 - Incidence of Brain Recurrence and Survival Outcomes in High-Grade Neuroendocrine Carcinomas of the Lung: Implications for Clinical Practice (ID 3879)
14:30 - 14:30 | Author(s): D. Giannarelli
- Abstract
Background:
Among patients with advanced high-grade neuroendocrine carcinoma (HGNEC) of the lung, the optimal therapeutic management is much less established for large cell neuroendocrine carcinomas (LCNECs) than for small cell lung cancers (SCLCs). We evaluated the survival outcomes and incidence of brain recurrence of advanced LCNECs, and compared them with those of a population of SCLCs matched by stage.
Methods:
Forty-eight unresected stage III HGNECs (16 LCNECs and 32 SCLCs) and 113 stage IV HGNECs (37 LCNECs and 76 SCLCs) were eligible for the analysis. The efficacy of platinum-etoposide chemotherapy with or without thoracic radiotherapy (TRT) and/or prophylactic cranial irradiation (PCI) was investigated.
Results:
Overall response was significantly lower for LCNECs compared with SCLCs for both stage III (43.8% vs 90.6% respectively, P=0.004) and stage IV (43.3% vs 64.5%, respectively, P=0.04). Similarly, an inferior outcome was observed in terms of progression-free survival (PFS), and overall survival (OS) for LCNECs compared with SCLCs, which, however, reached significance only for stage III disease (median: 5.6 vs 8.9 months, P=0.06 and 10.4 vs 17.6 months, P=0.03 for PFS and OS, respectively), (Figure 1). Histologic subtype (LCNEC vs SCLC) was an independent prognosticator in multivariate analysis. In the lack of PCI, LCNECs showed a high cumulative incidence of brain metastases, as 58% and 48% of still living stage III and IV patients, respectively, developed brain metastases at 18 moFigure 1
Conclusion:
Patients with advanced LCNECs are at high risk for brain recurrence. Unresected stage III LCNECs treated with platinum-etoposide with or without TRT bear a dismal prognosis, when compared indirectly with SCLC counterparts. Randomized trials should evaluate whether PCI could improve survival of advanced LCNECs.

P3.02c-095 - Italian Nivolumab Expanded Access Programme: Efficacy and Safety Data in Squamous Non Small Cell Lung Cancer Patients (ID 5159)
14:30 - 14:30 | Author(s): D. Giannarelli
- Abstract
Background:
Nivolumab monotherapy has shown survival benefit in patients (pts) with melanoma, lung cancer, renal cell carcinoma and head and neck cancer. The experience of pts and physicians in routine clinical practice is often different from those in a controlled clinical trial setting. Here, we report efficacy and safety of nivolumab monotherapy in pts with squamous non small cell lung cancer (Sq-NCSLC) treated in the nivolumab Expanded Access Programme in Italy.
Methods:
Nivolumab was available upon physician request for pts aged ≥18 years who had relapsed after a minimum of one prior systemic treatment for stage IIIB/stage IV Sq-NSCLC. Nivolumab 3 mg/kg wass administered intravenously every 2 weeks to a maximum of 24 months. Pts included in the analysis had received at least 1 dose of nivolumab and were monitored for adverse events (AE) using Common Terminology Criteria for Adverse Events.
Results:
In total, 371 Italian pts participated in the EAP across 96 centres and 363 patients were evaluable for response. With a median follow-up of 5.2 months (range 0-12.9) and a median of 7 doses, the best overall response rate (BORR) was 18%, with 3 complete responses (CR) and 62 partial responses (PR), and the disease control rate (DCR) was 47%. DCR was comparable among pts regardless previous lines of therapy, brain metastasis, age and smoking habits. A non-conventional benefit was observed in 23 (17 SD and 6 PR) out of 66 pts treated beyond RECIST defined progression. As of April 2016, median progression-free survival and median overall survival were 3.9 (95% CI: 3.2-4.6) and 9.1 (95% CI: 6.7-11.5) months, respectively. Regarding the safety profile, 267 out of 371 pts (72%) had at least one AE of any grade, considered to be drug-related in 106 pts (29%). Grade 3/4 AE were reported in 66 pts and considered to be drug-related in 20 pts (5%). AE were generally manageable following the specific guidelines.
Conclusion:
To date, this is the largest clinical experience with nivolumab in a real-world setting. These preliminary EAP data seems to confirm the efficacy and safety data of nivolumab from registrational trials, supporting its use in current clinical practice for pre-treated pts with Sq-NCSLC.
