MA26.02 - Upfront or Sequential Strategy for New Generation Anaplastic Lymphoma Kinase (ALK) Inhibitors: An Italian Retrospective Study. (ID 12790)
13:35 - 13:40 | Author(s): Fabiana Letizia Cecere

- Presentation
Background
Anaplastic lymphoma kinase (ALK) rearrangement confers sensitivity to ALK inhibitors (ALKis) in non-small-cell lung cancer (NSCLC). Although several drugs provided an impressive outcome benefit, the most effective sequential strategy is still unknown.
a9ded1e5ce5d75814730bb4caaf49419 Method
We retrospectively collected 242 ALK-positive advanced NSCLC diagnosed between 2010 and 2018 in 23 Italian institutions (expanded data collection from Gobbini et al. Lung Cancer 2017). 138 patients received exclusively crizotinib as ALKi (not considered for this analysis). 78 patients received crizotinib and a new (second or third) generation ALKis as further treatments (group A). 26 patients performed a new generation ALKi as upfront agent (group B). These groups are larger than those considered in a previous analysis (15 and 8 patients, respectively).

With a median follow-up of 22.6 months (CI 95% 20.09-25.10), 33 patients had died (32%). In group B, the median progression free survival (PFS) for new generation ALKis administered as first (14.0 months, CI 95% 9.52-18.471), second (12.7 months, CI95% 7.22-18.17) or third-line (12.8 months, CI95% 6.24-19.35) was not statistically different (p= 0.522). The median time from the start of crizotinib to the disease progression after the new generation ALKi sequentially performed (group A) was longer than that one detected in group B for the upfront new generation ALKis (29 vs 14 months, HR 2.47 [CI95% 1.35-4.50], p=0.003). This result was confirmed even considering the time lost between the two treatments in group A. The median overall survival (OS) was not reached. The 12-months OS rate was 97% in group A and 84% in group B.
8eea62084ca7e541d918e823422bd82e Conclusion
New generation ALKis maintain their efficacy regardless of the treatment setting considered. The sequential strategy seems to provide a substantial benefit, but a longer follow-up and larger samples are needed to clarify the survival impact.

P1.15-01 - Radiotherapy (RT) and Nivolumab in Non-Small-Cell Lung Cancer (NSCLC): A Multicenter Real-Life Experience (ID 12194)
16:45 - 18:00 | Author(s): Fabiana Letizia Cecere
- Abstract
Background
The combination of RT and programmed death 1 (PD-1) inhibitors seems augment antitumor immune responses. The aim of this study was to assess the outcome of patients (pts) with NSCLC previously undergone to RT before receiving nivolumab, a PD-1 inhibitor
a9ded1e5ce5d75814730bb4caaf49419 Method
We conducted an observational, retrospective analysis of 95 consecutive pts with advanced NSCLC who received any RT within 10 months prior nivolumab, as clinically indicated, at seven Italian institutions. Tumor response to treatment was defined according to RECIST criteria version 1.1. Median overall survival (OS) and the 95% confidence interval (CI) were estimated with the Kaplan -Meier method.
4c3880bb027f159e801041b1021e88e8 Result
95 pts (median age 66 years [range 41-82]; male:63.2%) with advanced NSCLC (adenocarcinoma [adc]:66.3%; squamous cells [sqc]:33.7%) were treated with nivolumab after RT. Median OS was 11.9 months (mo) [95% CI, 6.6-17.2 (adc: 13.0 mo [95% CI,6.7-19.3], sqc 10.5 mo [95%CI,3.9-17.1]). Median progression free survival (PFS) was 6.3mo [95% CI,4.6-8.0] (adc: 6.4 mo[ 95% CI,4.5-8.3]; sqc: 3.7 mo [95% CI,0.0-8.3]). A better performance status (PS) according to ECOG scale was associated with an improved OS (PS 0[38 pts]: 17.9 mo [95% CI,12.3-23.5; p<0.0001]; PS1[50pts]: 6.9 mo [95%CI,3.2-10.6]; PS2[7pts]: 4.4 mo [95% CI,3.9-4.9]). Median OS in 70 pts who received ≤ 1 previous systemic therapy was 13.0 mo [95% CI, 10.4-15.6] and in 25 pts who received ≥2 prior lines was 7.4 mo [95% CI, 1.8-12.9]. Median OS in 69 pts (72.6%) receiving extracranical RT was 12.0 mo [95%CI,6.6-17.4] and in 26 (27.4%) pts with cranial RT was 11.7 mo [95%CI,NE]; p=0.31. Median OS was shorter in 36 pts receiving bone-RT [7.3 mo; 95% CI, (0-15.3)] when compared with 59 pts receiving extra-bone RT [14.4 mo; 95% CI, (10.3-18.5); p=0.007]. Median OS in 68 pts aged < 70 years was 11.9 mo [95% CI,6.5-17.3] and in 27 elderly (≥ 70 years) was 12.0 mo [95% CI, 3.8-20.1]. 1 (1.0%) complete response, 25(26.3%) partial response, 28(29.5%) stable disease and 41 (43.2%) progressive disease have been observed.
8eea62084ca7e541d918e823422bd82e Conclusion
This study shows that combining irradiation with nivolumab for the treatment of advanced NSCLC leads to improve OS and promote tumor control both locally and distantly.This potentially synergistic effect was comparable among pts regardless previous lines of therapy, histology, type of RT and age.

P2.09-21 - Women with Synchronous or Metachronous Lung and Ovarian Cancers: A Multi-Institutional Report (ID 12485)
16:45 - 18:00 | Author(s): Fabiana Letizia Cecere
- Abstract
Background
In women, lung cancer (LC) and ovarian cancer (OC) are, respectively, the second and eighth malignancies for incidence in developed Countries. Despite increasing incidence and mortality of LC, association with OC is rare and no literature data are available on this topic yet. Our aim was to describe a series of patients with synchronous or metachronous LC and OC and to identify common clinical and pathological patterns.
a9ded1e5ce5d75814730bb4caaf49419 Method
We retrieved the medical charts of patients who referred to 30 European Oncological Institutes from 2008 to 2018. When patients with synchronous (up to 3 months of time interval in onset) or metachronous LC and OC were found, we collected detailed medical history, pathological features and clinical outcomes. Whenever available, formalin fixed paraffin embedded tumor tissue from both specimens was collected for centralized pathology revision with an immunohistochemical marker panel including TTF-1 and PAX-8. In ambiguous cases, a broader panel was performed (p40, CK-7, WT1, CA125, Calretinin, EMA, CEA, CgA, Vimentin, Napsin-A). Whenever tested, genetic alterations in LC and OC were also reported.
4c3880bb027f159e801041b1021e88e8 Result
As of April 2018, among 30 European Oncological Centers (Italy, France, Slovenia), 11 retrieved in their series patients with a history of LC and OC, for a total of 18 cases in the last 10 years. Paired histological specimens were available in 6 cases. One patient was excluded, since pathology revision revealed that lung lesions were metastases from serous OC. Thus, analyses were performed on 17 patients. In 10/17 cases (58.8%), LC and OC were metachronous and, in 6/10 cases, OC preceded LC diagnosis, with a median interval of 4.5 years. Median age at diagnosis of the first malignancy was 62 years, the majority of patients (64.7%) were never-smoker, 6 had cancer familial history. Interestingly, 4 patients (23.5%) reported also a third or fourth malignancy. After a median follow-up of 6.5 years, 10 patients are alive. Regarding histology, most of LC were adenocarcinoma (14/17, 82.3%). Molecular status was available in 9/14 cases: 4 had EGFR mutation, 1 B-RAF mutation and 2 ALK translocation. OC were mostly high-grade serous (83,3%). BRCA status was available in 6 patients: 2 mutated, 2 wild-type and 2 affected by variants of unknown significance (USV). Moreover, one synchronous case presented both BRCA-USV and B-RAF mutation.
8eea62084ca7e541d918e823422bd82e Conclusion
In our series, synchronous and metachronous LC and OC were often driven by genetic alterations. Further genetic analysis with next generation sequencing technology has already been planned.
