Abstract Background Treatment outcomes of advanced non-small cell lung cancer (NSCLC) have substantially improved with immune checkpoint inhibitors (ICI), although only approximately 19% of patients respond to immunotherapy alone, increasing to 58% with the addition of chemotherapy. The gut microbiome has been recognized as a modulator of ICI response via its priming effect on the host immune response. Antibiotics as well as chemotherapy reduce gut microbial diversity, hence altering composition and function of the gut microbiome. Since the gut microbiome may modify ICI efficacy, we conducted a retrospective study evaluating the effects of prior antibiotic or chemotherapy use on NSCLC patient response to ICI.Methods We retrospectively evaluated 256 NSCLC patients treated between 2011-2017 at Moffitt Cancer Center with ICI ± chemotherapy, examining the associations between prior antibiotic or chemotherapy use, overall response rate and survival. Relative risk regression using a log-link with combinatorial expectation maximization algorithm was performed to analyze differences in response between patients treated with antibiotics or chemotherapy versus patients who didn’t receive antibiotics or chemotherapy. Cox proportional hazards models were constructed to evaluate associations between risk factors and overall survival. Results Only 46 (18% of 256) patients used antibiotics prior to and/or during ICI treatment, and 146 (57%) had prior chemotherapy. Antibiotic users were 8% more likely to have worse overall response rate (RR:1.08; CI:0.93-1.26; p=0.321), as well as a 35% worse overall survival (HR:1.35; CI:0.91-2.02; p=0.145), although results were not statistically significant. However, prior use of chemotherapy was significantly associated with poor ICI response (RR:1.24; CI:1.05-1.47; p=0.013) and worse overall survival (HR:1.47; CI:1.07-2.03; p=0.018). Conclusions Patients receiving antibiotics prior to and/or during ICI therapy might experience worse treatment outcomes and survival than unexposed patients, although these associations were not statistically significant and hence warrant further prospective study. Prior chemotherapy significantly reduced ICI response and overall survival. Antibiotic or chemotherapy exposure may negatively impact ICI response, perhaps through disruption of the eubiotic gut microbiome.

Thirty-one patients with non-small-cell lung cancer (NSCLC), stage III (T3 N2 M 0-1), were treated with cyclophosphamide (400 mg/m2), adriamycin (40 mg/m2) and cisplatin (60 mg/m2) (CAP) every 4 weeks for 8 cycles. Twenty-six patients were evaluable for response. Patients characteristics included: median age, 63 years; median performance status, 70% (range 60% -100%). One hundred and fifty-five cycles of chemotherapy were administered with a median of 5. There were 9 partial responses and 3 complete remissions, for an overall response rate of 46%. The median survival duration was 9 months, and 29% survived 1 year. CAP combination chemotherapy was well tolerated without nephrotoxicity, which can be imputed to the strong saline hydration given. Seventy percent of the patients did not experience emesis due to the antiemetic regimen used.

Thirty-eight patients with histologically confirmed non-small-cell lung cancer were treated with bleomycin, vincristin, mitomycin and cisplatin (BOMP) alternated with cyclophosphamide, 4'-epidoxorubicin and procarbazine (CEP). Twenty patients were randomized to start the treatment with BOMP and 18 with CEP. Patients underwent a median of 4 cycles (range, 1-8). The overall response rate was 36% with 2 clinical complete responses. The median duration of response was 6.5 months, the median survival time was 7.5 months, and 37% of patients survived for more than one year. The comparison between the two arms of this study and between this study and a previous investigation on the effectiveness of BOMP suggests that CEP regimen added to BOMP does not significantly improve patient outcome.

e18104 Background: Advanced research and better understanding of the human immune system has led to the development of targeted immunotherapy such as PD-1 inhibitors. We studied patients with both squamous and non-squamous Non-Small Cell Lung Cancer in a community setting who are being treated with Nivolumab. Our primary objective was to determine response to therapy (overall response rate-ORR). Our secondary objective was to study the abscopal response of our population and if the tumor response was better in those patients who received radiotherapy in the preceding 6 months of the start of immunotherapy Methods: Data were summarized using descriptive statistics including means, standard deviations, medians, frequencies and percentages. Chi square analyses were used to make comparisons between response and categorical variables. Overall response rate was calculated by combining people with partial and complete response. All p-values were two tailed and a level of ≤ 0.05 was considered significant. Results: Out of 21 patients, eight (38%) did not show any disease progression. Five out of these eight patients (23% of total study population) had stable disease. Three remaining patients had partial response to the treatment. The ORR was 14% which is comparable to 20% and 19% ORR in the CheckMate trials for nivolumab. Thirteen (62%) patients had progressive disease. Our study showed no significant effect of radiotherapy on disease response to nivolumab. There was one incidence of treatment discontinuation permanently due to the side effects of Nivolumab. Conclusions: Immunotherapy is a promising new option in lung cancer treatment. Fewer side effects and improved survival compared to traditional second line chemotherapy makes it more appealing. In our study group, nivolumab has shown ORR of 14% and stable disease in an additional 23% of the patients resulting in a disease control rate of 37%.

PurposeTo evaluate the efficacy of cetuximab added to first-line gemcitabine/platinum in chemotherapy-naïve patients with advanced non–small-cell lung cancer (NSCLC).Patients and MethodsIn this noncomparative, randomized trial, chemotherapy-naïve patients with recurrent/metastatic NSCLC (stage IV or stage IIIB with malignant pleural effusion) were eligible. Patients received cisplatin (75 mg/m2IV, every 3 weeks) or carboplatin (area under the concentration-versus-time curve of 5 intravenously [IV], every 3 weeks), and gemcitabine (1,250 or 1,000 mg/m2IV, days 1 and 8) plus cetuximab (400 mg/m2IV day 1, followed by 250 mg/m2weekly), in arm A, or chemotherapy alone, in arm B. Response rate was the primary end point; safety, progression-free survival, and overall survival were secondary end points.ResultsSixty-five patients were randomly assigned to arm A and 66 to arm B. Partial responses were observed in 18 patients (27.7%; 95% CI, 17.3 to 40.2) in arm A and 12 (18.2%; 95% CI, 9.8 to 29.6) in arm B. Median progression-free survival was 5.09 months for arm A (95% CI, 4.17 to 5.98) and 4.21 months (95% CI, 3.81 to 5.49) in arm B. Median overall survival was 11.99 months (95% CI, 8.80 to 15.18) and 9.26 months (95% CI, 7.43 to 11.79) in arms A and B, respectively. Overall toxicity was acceptable and consistent with the profiles of the individual agents.ConclusionFirst-line treatment with cetuximab plus gemcitabine/platinum is well tolerated and can be administered safely in patients with advanced NSCLC. Differences in response rate, progression-free survival, and overall survival suggest that the addition of cetuximab to platinum/gemcitabine may improve clinical outcomes. Larger studies are in progress to address this hypothesis.

Background Studies suggest that bevacizumab-induced hypertension is prognostic of better outcomes in bevacizumab-treated patients with metastatic colorectal, HER2-negative breast, kidney, and pancreatic cancer. Few have examined this correlation in metastatic non-small cell lung cancer and evaluated whether hypertension independent of bevacizumab can improve the treatment outcomes. Objectives The primary objective was to determine the effect of hypertension on the overall response of advanced non-small cell lung cancer patients from start of the first-line chemotherapy to maintenance therapy. Secondary objectives include the effect of hypertension on the overall survival in all patients and on the overall response in bevacizumab-treated patients. Methods A retrospective chart review for a single institution was conducted from 2008 to 2013 on all patients with advanced non-squamous non-small cell lung cancer who received ≥ 1 cycle of combination chemotherapy. Patients were divided into hypertension versus no hypertension and into bevacizumab versus non-bevacizumab groups. Results Of the 188 advanced non-small cell lung cancer patients evaluated, 62 were treated with bevacizumab-containing regimens. The mean age at diagnosis was 58 years in both the groups. Hypertension independent of bevacizumab did not lead to improved treatment outcomes. However, in the bevacizumab subgroup, hypertensive patients had significantly higher response rates versus non-hypertensive patients (36.7% vs. 12.5%; p = 0.02). There was no significant difference in the overall survival between hypertensive versus non-hypertensive patients. Conclusion While hypertension alone did not significantly improve the treatment outcomes, hypertension in bevacizumab-treated patients with metastatic non-small cell lung cancer led to significantly improved responses. Further prospective studies are needed to confirm the association of hypertension with improved treatment outcomes in metastatic NSCLC.

PURPOSE The antineoplastic activity of carboplatin and etoposide may be improved by the addition of vincristine (CEV) because of its low myelosuppressive potential and its activity in small-cell lung cancer (SCLC). A phase II study with CEV was carried out. PATIENTS AND METHODS One hundred twenty-one untreated patients with SCLC (63 with limited disease [LD], 58 with extensive disease [ED]) were treated with a combination of 300 mg/m2 intravenous (IV) on day 1, etoposide 140 mg/m2 IV daily on days 1 to 3, and vincristine 1.4 mg/m2 IV on days 1, 8, and 15 every 4 weeks. RESULTS A 90% rate overall response rate including 56% complete responses (CRs) was achieved in LD and an 83% overall response rate including 35% CRs was observed in ED. Median survival time was 13 months in limited disease and 9.5 months in extensive disease. The 24 and 36 months survival rates were 29% in LD and 9% in ED. Myelosuppression was the main form of toxicity. CONCLUSION The combination of CEV is a new active and well-tolerated regimen in the treatment of SCLC. Prospective randomized studies of CEV with conventional chemotherapy are warranted.

18177 Background: The efficacy and safety of a combined regimen of topotecan and etoposide was tested in patients with relapsed or refractory small-cell lung cancer. Methods: From October 2003 to May 2005, 23 patients who have failed to the previous irinotecan and platinum chemotherapy received intravenous topotecan 1mg/m2 (day 1–5) followed by intravenous etoposide 80mg/m2 (day 1–3). Treatment was repeated every 21 days for a maximum of 6 cycles. Results: Twelve patients were refractory to first-line chemotherapy. Seventeen patients (73.9%) were male and the median age was 63 years. ECOG performance status was 0–1 in 13 (56.5%) patients. The median cycles of chemotherapy was 3. Twenty one patients were assessable for response evaluation. The overall response rate was 17.4% (0 CR, 4 PR, 7 SD, 10 PD) under the intent-to-treat analysis. After a median follow- up of 20.8 months, median progression free survival was 4.7 months and median overall survival was 9.5 months. The estimated 1-year survival rate was 38.7%. In sensitive relapsed patients, 2 achieved tumor response and median progression free survival and overall survival were 5.5 months and 14.5 months. All patients were assessable for toxicity and major toxicities were myelosuppression. Grade 3/4 neutropenia and thrombocytopenia occurred in 18 (78.3%) and 12 (52.2%) patients, respectively. Grade 3/4 febrile neutropenia occurred in 2 patients (8.7 %) and infection in 3 patients (13.0%). There was one treatment-related death due to pneumonia. Conclusions: This salvage regimen failed to demonstrate a considerable response rate compared with monotherapy for relapsed or refractory SCLC. However, the combination of topotecan and etoposide could be further studied for sensitive relapsed patients pretreated with irinotecan and platinum No significant financial relationships to disclose.

e21149 Background: EGFR mutations are detected in 15-62% of patients with non-small cell (NSCLC) lung cancer. We can use tyrosine kinase inhibitors (such as erlotinib, gefitinib, afatinib) to treat patients with EGFR-mutant lung cancer. Tyrosine kinase inhibitors improve the survival outcomes of the patients. This study aimed to assess predictors of overall response rate (complete or partial response) in EGFR-mutant non-small cell lung cancer patients treated with EGFR inhibitors. Methods: Data of the EGFR-mutant lung cancer patients were evaluated retrospectively. Clinical, pathological, radiological, and treatment features of the patients were recorded. SPSS 25 version was used for statistical analysis. Kaplan-Meier and Cox-regression methods were used for survival analysis. Also, predictors of overall response were evaluated with logistic regression analysis. Results: 105 patients were included in the study. The female/male patients ratio was 1.25, and the median age was 61 (range, 33-85) years. Adenocarcinoma (90.4%) was the most common histopathological type. The ratios of Exon 19, exon 21, and other (rare or multiple) mutations were 59%, 25%, and 16%, respectively. 89 (84.9%) patients were de-novo metastatic at diagnosis. Before EGFR inhibitor therapy, the patients had received chemotherapy (22.9%) and palliative radiotherapy (40%). The patients received erlotinib (83.8%) or other EGFR inhibitors (16.2%) for treatment. Median overall survival was 30.8 (range 20.2-41.4) months. Overall response rate (complete or partial response) was 61.9%, stable response 11.4%, and progressive disease 26.7%. In logistic regression analysis, we found that age (p = 0.008), number of metastasis sites (p = 0.037), pathological type (adenocarcinoma or other types) (p = 0.001) were statistically significant for the overall response rate. However, gender (p = 0.98), tumor localizations (left or right lung) (p = 0.39), de-novo metastasis (p = 0.81), EGFR mutations type (p = 0.13), and type of EGFR inhibitör (p = 0.30) were not statistically significant. Conclusions: In this study, we showed real-life outcomes of the patients with EGFR-mutant metastatic non-small cell lung cancer. The data of predictors of overall response for EGFR inhibitors is limited. We detected that age, the number of metastatic organs, and histopathological type of tumor were affected the response of treatment.
