      • Slides

      Background

      No phase III trials have been carried out to prove the value of a platinum-doublet rechallenge in p with NSCLC. Currently, the availability of different effective drugs makes the platinum-based salvage therapy unusual. Moreover, the potential cumulative toxicity related to cisplatin or carboplatin can be an issue. However, retreatment with platinum-based CT could be hypothetically proposed for p with a long time to progression (TTP) from the last platinum treatment, in p with a good performance status, who may be symptomatic and with no formal contraindication to receive such treatment We have retrospectively reviewed experience at our institution of platinum-based chemotherapy rechallenge in stage III and IV NSCLC p

      Method

      A cohort of 376 p with stage III and IV NSCLC treated with first-line platinum doublets from January 2012 to December 2017 were included. We extracted information on clinical and molecular characteristics, as well as treatment details. Time to progression was evaluated by Kaplan-Meier curves and groups were compared using Log-rank test.

      Result

      Overall, 57 p were rechallenged with platinum-based CT (group A). Median age was 57 years (51.5-65) for rechallenged p versus (vs) 62 (56.2-68.8) for the entire cohort (group B)[p=0.001]. Group A include more p with stage III p( 54.4% vs. 30.7%; p=0.001), as well as more p with better ECOG Performance Status (PS) (PS 0 70.2% vs. 44.5%; p=0.001). No differences in gender, smoking status, histology and comorbidities were observed between both groups (20.7% and 29.8% were women and 38.6% and 53.9% were smokers in groups A and B, respectively).

      No differences in molecular profile (EGFR, ALK, ROS1, KRAS, BRAF) were observed. The most common platinum doublet administered in first line setting was cisplatin plus pemetrexed. Group A received more frequently carboplatin plus gemcitabine or vinorelbine. Disease Control Rate (DCR) was 57.9% in p included in group A. No differences in DCR were observed in first line between both groups. Time to progression or death was 9.6 m for gropuo B(5-18.1) vs 20.5 m (14.6-37.3) p <0,001 for p in group A.

      Conclusion

      Rechallenge with platinum-based CT doublets could represent an option for NSCLC p with good PS and no contraindications for such therapy.

      EP1.04-25 - Increased PD-L1 Expression in MET Amplified (AMP) Advanced Non Small Cell Lung Cancer (NSCLC) Patients (P) (ID 2764)

      08:00 - 18:00  |  Author(s): Marta Domenech

      • Abstract
      • Slides

      Background

      MET amp has been reported in a subset of NSCLC p and treatment with crizotinib has proved clinical activity in cases of MET exon 14 alterations and MET amp.. Recently, immunotherapy has emerged as a new approach to treat NSCLC. The development and success of programmed cell death 1 (PD-1)/program death-ligand 1 (PD-L1) checkpoint inhibitors has been correlated with PD-L1 status, particularly in NSCLC p whose tumors express high PD-L1 levels by tumor proportion score (TPS) ⩾ 50%. In this study we have reviewed the PD-L1 status in a cohort of advanced NSCLC p with a METamp.

      Method

      PDL1 expression has been evaluated in a retrospective cohort of NSCLC p with MET amp and wild type for EGFR, KRAS, BRAF mutations and ALK and ROS1 rearrangements. Overall Survival (OS) was evaluated with Kaplan-Meier curves and groups were compared using log-rank test. Clinical and tumor characteristics, as well as treatment details, were evaluated. MET amp was analyzed by FISH, while PD-L1 status was assessed by immunochemistry by SP 263. antiboby

      Result

      A total of 50 p were included, 15 p has high or intermediate Met amp and 35 p had low or negative Met amp. Median age were 66 years old. 39 (78%) p were male, 43 (86%) p were smokers or former smokers, 37 p (74%) were ECOG PS 0-1, 37 p (74%) were stage IV. PD-L1 were negative ( < 1%) in 21 p (42%), positive ( >1%) in 26 p ( 52%). PD-L1 highly positive in 18 p ( 36%). Statistically significant more p had PD-L1 positive ( TPS > 1%) in high or intermediate Met amp p versus low or negative ( 92.9% vs 39.4%; p 0.001). And high or intermediate Met amp p had PD-L1 high expression ( TPS > 50%) than negative or low Met amp p ( 64.3% vs 27.3%; p 0.020). No differences in PD-L1 expression was observed by gender, ECOG PS or smoking status. Median OS was 16.367 m (2.295-30.438). No differences in OS were seen by PD-L1 expression or Met amp status.

      Conclusion

      PD-L1 expression in NSCLC p is positively correlated with MET amp, especially in p with PD-L1 > 50%. Our data suggests that MET amp may play a direct role in up-regulating PD-L1 expression in NSCLC p. Additionally, combination therapy targeting MET and checkpoint inhibition should be considered as a potential therapeutic strategy for NSCLC p with high and intemediate MET amp.

      EP1.16-17 - Management of Inappropriate Use of Opioids (IUO) in Patients (P) with Lung Cancer (LC) (Now Available) (ID 612)

      08:00 - 18:00  |  Author(s): Marta Domenech

      • Abstract
      • Slides

      Background

      Pain represents one of the main symptoms in patients (p) with lung cancer (LC). Currently, the molecular classification and targeted therapies and immunotherapy for LCp yield a prolonged survival in some p. In this context, analgesia with opioid therapy (OT) requires special caution. The prevalence of IUO LCp is unknown and its assessment is suboptimal. There is no current recommendation to assess IUO risk in cancer p, other than in long cancer survivors with chronic pain. Several scales are validated for the screening of aberrant OT-behaviors. The Addiction Unit (AU) role could be key in the evaluation and minimization of the IUO risk (Fig.1)

      STUDY DESIGN:Prospective study for the evaluation of IUO risk in LCp. P with intermediate/high risk of IUO will be referred to the AU for evaluation and follow-up (Fig.1)

      OBJECTIVES:Determine if screening scales are capable of detecting the risk of IUO in LCp. Reduce the impact of IUO in LCp by assessment and follow-up in the AU.

      VARIABLES: Main: To determine if the Cut down-Annoyed-Guilty-Eye opener (CAGE-AD) and Opioid Risk Tool (ORT) scales are able of detecting the risk of IUO in LCp. Secondary: Determine if the urine and blood drug testing (DT) reinforces the information of such scales. Determine the risk reduction of IUO after the intervention of the AU.

      Method

      ELIGIBILITY CRITERIA (Fig.1)

      SCALES:The MO team will use the following scales for the IUO risk assessment: CAGE-AID, ORT. Visual Analogic Scale (VAS) and Edmonton Symptom Assessment Scale (ESAS) will be used for pain evaluation. LABORATORY: DT (urine/ blood ethanol)

      ASSESSMENT OF IUO RISK: Proposed timeline and strategies at the AU are summarized in Fig.1.

      SAMPLE SIZE:Study will include 45 p in a 1-year period.

      P1.01-54 - Somatic Genome Alterations in Lung Cancer Patients Diagnosed with Li Fraumeni Syndrome (Now Available) (ID 1014)

      09:45 - 18:00  |  Author(s): Marta Domenech

      • Abstract
      • Slides

      Background

      Li-Fraumeni syndrome (LFS) is a rare hereditary condition that consists of TP53 mutations inherited in autosomal dominant manner that confer high risk of developing cancer, including lung adenocarcinoma (LUAD). EGFR-mutated LUAD were reported in the context of LFS but there is no systematic description of somatic mutations and characteristics of lung cancer (LC) patients with LFS.

      Method

      We present a retrospective analysis of clinical and molecular characteristics of patients with LFS diagnosed with LC at the Catalan Institute of Oncology from 1999 to 2019. We collected demographical and clinicopathological features, germline and somatic mutational alterations, treatment and progression-free survival (PFS) and overall survival (OS).

      Result

      A total of 7 patients with LC and LFS were identified in the Genetic Counseling Unit database. They were carriers of germline mutations in TP53. Five of them were classified as pathogenic: c.638G>A; p.(Arg213Gln), c.725G>A; p.(Cys242Tyr), c.742C>T; p.(Arg248Trp), c.844C>T; p.(Arg282Trp) and c.1010G>A; p.(Arg337His) and two of them as likely pathogenic: c.374C>T; p.(Thr125Met) and c.473G>A; p.(Arg158His). Six out of 7 patients were female and 5 out of 7 never smoker. Median age at diagnosis was 38 year-old (range: 29-74). Five patients had stage IV at diagnosis and the most common histologic subtype was LUAD (5). Six patients had first grade family history of cancer with a median of 2 family members (range: 1-4) and 2 patients had prior history of cancer. Tumor somatic profile in LC was obtained in 6 patients, consisting on a ROS-1 rearrangement in one patient and EGFR mutations in 5 patients (exon 19 deletion in 3 patients and missense mutations in 2 patients, p.(Gly719Ala) at exon 18 and p.(Leu858Arg) at exon 21) and in 1 patient was unknown. All patients with mutant EGFR received EGFR tyrosine kinase inhibitors (TKI) with a median PFS of 29 months (95% CI 0-67). Four had partial response and one a complete response to TKI treatment. At disease progression, one patient had small cell transformation and another acquired EGFR T790M mutation. Median lines of treatment were 4 (range 1-6). Two patients are alive at data cut off. Median OS is 47 months (95% CI 32-62).

      Conclusion

      Patients diagnosed with LC and LFS are enriched with actionable genomic alterations and have an earlier onset of the disease. Clinical outcome of patients with EGFR mutations and LFS did not differ from EGFR mutated LC patients who do not carry TP53 germline mutations.

      P1.16-44 - Multiple Primary Cancers (MPC) in a Cohort of Lung Cancer (LC) Patients (P): Incidence and Clinical Features (ID 2236)

      09:45 - 18:00  |  Author(s): Marta Domenech

      • Abstract

      Background

      The prognosis of p with LC has drastically changed during the last decade due to the improvement in prevention, diagnosis and treatment. Therefore, the number of LC survivor ps has significantly increased and subsequently the incidence of MPC is also rising. This study investigates the co-occurrence of MPC among p diagnosed with LC.

      Method

      We reviewed of clinical data of patients with histologically confirmed LC visited at our institution between February 2016 and December 2018.

      Result

      A total of 492 p out of 777 p, (63.3%) had adenocarcinoma and 223 p (28.7%) had squamous LC. The most frequently related comorbidities were hypertension (42.5%), dyslipidemia (36.2%), COPD (21%), cardiovascular disease (15.7%) and diabetes mellitus (14.5%). Molecular analysis was perform in 402 p (51.7%). EGFR mutation was detected in 77 p (exon 19 in 14% and exon 21 in 5% of p). ALK and ROS1 translocation were diagnosed in 27 and 7 p, respectively.

      Two primary cancers occurred in 111 cases (14%), including 15 p (1.9%) with three or more primary cancers. Patients with MPC were predominantly males (76.8%), smokers (85%) and 34% had prior family history of MPC. Median age at the first tumor diagnosis was 64 years (57-71). LC occurred as first neoplasm in 8.1% of the cases, 92 p (83%) developed metachronic MPC and 19 p (17%) synchronous MPC. Most common secondary primary cancer were head and neck in 19%, non-melanoma skin cancer in 19%, prostate in 12.6%, bladder and upper urinary tract cancer in 10%, colorectal in 6.3% and breast in 5.4%.

      First-line treatment for advanced or locally advance LC included chemotherapy in 65.6%, concomitant chemoradiotherapy in 14%, targeted therapy in 4% and immunotherapy in 4%. Overall response rate (ORR) to first-line treatment was 43.7%. Second-line treatment included chemotherapy in 47.6% and immunotherapy in 30.4%, with and ORR of 30%.

      Conclusion

      In our series, the frequency of the co-occurrence of MPC among LC p is 14%, suggesting that surveillance strategies are recommended in this population. Most frequent MPC in LC patients are related to smoking. ORR in first and second-line are consistent with the literature.

      P2.10-02 - Smoking Habit in Lung Cancer in Spain   (ID 732)

      10:15 - 18:15  |  Author(s): Marta Domenech

      • Abstract
      • Slides

      Background

      Tobacco is the leading cause of lung cancer. The fight against the smoking habit is essential and should be continuous, to detect the national situation that makes it possible to design health care policies against this consumption. To do so, the Grupo Español de Cáncer de Pulmón (Spanish Lung Cancer Group) made this analysis within the context of the Thoracic Tumor Registry (TTR).

      Method

      The TTR is an observational cohort multicenter study in Spain. The study is conducted according to the Declaration of Helsinki and approved by the institutional review board of each participating site. The registry was approved by the Spanish Drug Agency, as a non-post-authorization, non-interventional study.

      Result

      We collected data from 6,600 patients diagnosed of lung cancer from 58 different Spanish hospital sites.

      A total of 3,039 patients were former smokers (46%), 2,611 were active smokers (39%) and only 866 (12%) patients stated to be non-smokers; the status in 2% is unknown. If we make a comparison by gender regarding the presence of this habit, large differences (p-valor < 0.001) are observed, with a greater number of non-smokers in women (37 % vs. 4.5% in males), while the percentage of former smokers is much higher in the males (53.4% vs. 27.9% in women) and a minor difference in active smokers (42.1% vs. 34.4% in women).

      Significant differences were observed in the study on the distribution of the smoking habit by gender and year of diagnosis. An increase is also observed in the last two years regarding the percentage of patients who were active smoked, both for the total population as well as for each one of the two genders separately. The increase is greater among the women and, also, the number of women who are active smokers is greater in recent years.

      Mean age of onset of the smoking habit is 18.2 years. Significant differences are observed between both genders (p-valor < 0.001), with a mean age of initiation of 17.9 years in the men (95%CI 17.6-18.2 years) and 19.2 years in the women (95%CI 18.5-19.8 years). Significant differences between Regional Communities were also found in the mean age at onset of the habit, with much lower levels in the Valencian Community (16.6 years) or Navarra (16.9 years) regarding other communities, such as the Region of Murcia (22.9 years) or the Balearic Islands (21.6 years)

      Conclusion

      Lung cancer in Spain is associated to tobacco consumption in 85% of the cases diagnosed. Consumption has shown an increase in both genders in recent years and is especially rapid and worrisome in women. Anti-smoking campaigns should be reactivated and the causes of the regional differences analyzed in depth
