Number of cycles of chemotherapy in patients with advanced non-small cell lung caner: Efficacy and relationship with histology.

e18125 Background: Platinum based regimens are standard first-line treatment in patients with advanced non mall cell lung cancer. We intend to evaluate their effectiveness according to the number of cycles administered, and investigate whether histology is a predictor of benefit from a greater number of infusions. Methods: 124 patients with stage IV NSCLC were evaluated retrospectively. They were divided according to whether they made 4 or 6 cycles of chemotherapy. The schemes used were: Cisplatin / Gemcitabine and Carboplatin / Paclitaxel, at standard doses. We studied the efficacy in both groups according to the most common histologies (adenocarcinoma and squamous cell carcinoma). PFS (progression-free survival) and OS (overall survival) were calculated by the Kaplan-Meier curves and compared by the Log Rank Test. Results: Those who underwent 4 cycles had a PFS of 7.77 months and OS of 12.2 months vs. 8.64 and 10.8 months those who received 6 cycles (p = 0.47, p = 0.76). Within the subgroup with squamous histology (n = 43), PFS and OS were 7.38 and 13.38 months respectively in the group that received 4 cycles vs. 7.97 and 9.76 months in those receiving 6 (p = 0.70, p = 0.32 ). Within adenocarcinoma histology (n = 81), those who received 4 cycle, has a PFS of 8.17 months and they lived 11.56 month, vs 8.96 and 10.79 months for those receiving 6 cycles (p = 0.29, p = 0.88) Conclusions: In our population, a greater number of cycles showed no advantages in terms of progression-free survival or overall survival. Histology is not a predictive factor for deciding how many chemotherapy cycles administer.

1021 Background: An increasing number of metastatic HER2 positive cancers represent de novo stage IV disease as fewer early stage patients relapse. We hypothesize that a subset of these has long progression free survival (PFS) after initial combined modality HER2-targeted therapies. Methods: 483 patients with de novo stage IV HER2 positive breast cancer diagnosed between 1998-2015 were identified through the medical records at Yale and MD Anderson Cancer Centers, respectively. Treatment, clinical variables and survival were extracted and compared between those who achieved “no evidence of disease” (NED) status with initial therapy and those who did not. Results: All patients received trastuzumab and 94 (20%) also received pertuzumab as first line therapy.The median OS was 5.5 years (95% Cl: 4.8-6.2); OS rates at 5 and 10 years were 54% (95% CI: 48%-60.4%) and 18% (95% Cl: 11.4%-28.3%), respectively and PFS were 41% (95% CI: 35%-48%) and 41% (95% CI: 35%-48%). Sixty-three patients (13.0%; 95% CI: 10.2% -16.4%) achieved NED. The PFS and OS at 5 and 10 years were the same 100% and 98% (95% CI: 94.6%-100%), respectively. For patients with no-NED (n = 420), the median OS was 4.7 years (95% Cl: 4.2-5.3), the PFS and OS rates at 5 and 10 years were 12% (95% CI: 4.5%-30.4%) and 0% and 45% (95% CI: 38.4%-52.0%) and 4% (95% CI: 1.3%-13.2%), respectively. NED patients had significantly longer progression free survival (log-rank test p≤0.001) and overall survival (log-rank test p≤0.001), more frequently had single organ site metastasis (76% vs 57%, p = 0.005), and more frequently had surgery for primary tumor (59% vs. 25%, p ≤0.001) than no-NED patients, but there was no significant difference in age, grade, race, year of diagnosis, ER status, treatment distribution, or radiation between the groups. Conclusions: About 13% of de novo, stage IV, HER-2 positive MBC patients achieved NED with HER-2 targeted therapies, all of these patients were progression free at 5 years and overall survival at 10-years was 98% compared to 4% among those with no-NED in our data sets. These results suggest that aggressive multimodality therapy of newly diagnosed stage IV HER2 positive cancers to render them NED may be warranted.

423 Background: Advanced PDAC remains a deadly disease with a 5-year survival rate of less than 10%. cfDNA - based next generation sequencing (NGS) may identify actionable alterations in patients with PDAC. In this study, we aim to determine the feasibility of utilizing serial cfDNA NGS testing and its potential relevance in predicting therapeutics outcomes. Methods: A total of 23 PDAC patients with PDAC cfDNA isolated from plasma collected at diagnosis and upon disease progression to first line SOC therapy and were analyzed on a 73-74 gene NGS panel (Guardant Health). Changes in molecular profiles from baseline to progression were analyzed for overall survival, progression free survival (PFS), and treatment response. PFS and OS were analyzed using the Kaplan-Meier method and the log-rank test was used to compare the survival of different groups of patients. All p-values were two-sided. Analyses were performed using R (version 3.5.1, R Foundation, Vienna, Austria). Results: In this retrospective study, the 1-year probability of survival was 71% (median 473 days) and the 1-year PFS was 14% (median 212 days). TP53 and KRAS were the most frequently mutated genes identified in baseline samples, with 78% prevalence for each. Patients with clearance of TP53 17% (3/18) patients and/or KRAS 33% (6/18) patients clones after first line therapy significantly increases PFS (p=0.0056 and p=0.037, with HR of 0.087 and 0.32, respectively). However, appearance of TP53 or KRAS alterations upon progression does not significantly affect overall survival or PFS. Conclusions: The preliminary results from this study suggest that cfDNA clearance of TP53 and/or KRAS alterations may predict for improved PFS in PDAC. Confirmation of these findings in larger studies is warranted.

Purpose A randomized, phase III trial demonstrated superiority of sunitinib over interferon alfa (IFN-α) in progression-free survival (primary end point) as first-line treatment for metastatic renal cell carcinoma (RCC). Final survival analyses and updated results are reported. Patients and Methods Seven hundred fifty treatment-naïve patients with metastatic clear cell RCC were randomly assigned to sunitinib 50 mg orally once daily on a 4 weeks on, 2 weeks off dosing schedule or to IFN-α 9 MU subcutaneously thrice weekly. Overall survival was compared by two-sided log-rank and Wilcoxon tests. Progression-free survival, response, and safety end points were assessed with updated follow-up. Results Median overall survival was greater in the sunitinib group than in the IFN-α group (26.4 v 21.8 months, respectively; hazard ratio [HR] = 0.821; 95% CI, 0.673 to 1.001; P = .051) per the primary analysis of unstratified log-rank test (P = .013 per unstratified Wilcoxon test). By stratified log-rank test, the HR was 0.818 (95% CI, 0.669 to 0.999; P = .049). Within the IFN-α group, 33% of patients received sunitinib, and 32% received other vascular endothelial growth factor–signaling inhibitors after discontinuation from the trial. Median progression-free survival was 11 months for sunitinib compared with 5 months for IFN-α (P < .001). Objective response rate was 47% for sunitinib compared with 12% for IFN-α (P < .001). The most commonly reported sunitinib-related grade 3 adverse events included hypertension (12%), fatigue (11%), diarrhea (9%), and hand-foot syndrome (9%). Conclusion Sunitinib demonstrates longer overall survival compared with IFN-α plus improvement in response and progression-free survival in the first-line treatment of patients with metastatic RCC. The overall survival highlights an improved prognosis in patients with RCC in the era of targeted therapy.

Introduction Almost half of patients with non-small-cell lung cancer (NSCLC) are diagnosed at an advanced stage. Our aim was to assess the effects of adding necitumumab to chemotherapy in patients with stage IV NSCLC. Material and methods A comprehensive literature search was performed according to pre-specified inclusion and exclusion criteria. Data on overall survival, progression-free survival, objective response rate and adverse events were extracted. A meta-analysis was performed to obtain pooled hazard ratios (HR) and corresponding 95% confidence intervals (CI) for time-to-event data and pooled odds ratio (OR) with 95% CI for dichotomous outcomes. Results The meta-analysis included four randomized clinical trials with 2074 patients. The pooled results showed significant improvement for overall survival (HR = 0.87 (95% CI 0.79–0.95), p = 0.004) when necitumumab was added to chemotherapy in patients with advanced NSCLC. No statistically significant improvement was noted for progression-free survival and objective response rate (HR = 0.83 (95% CI 0.69–1.01), p = 0.06 and OR = 1.46 (95% CI 0.90–2.38), p = 0.13, respectively). Subgroup analysis showed that in patients with non-squamous NSCLC, there was no benefit in overall survival and objective response rate. Patients with advanced NSCLC who received necitumumab were at the highest odds of developing a skin rash (OR = 14.50 (95% CI 3.16–66.43), p = 0.0006) and hypomagnesaemia (OR = 2.77 (95% CI 2.23–3.45), p < 0.00001), while the OR for any grade ≥3 adverse event was 1.55 (95% CI 1.28–1.87, p < 0.00001). Conclusions The addition of necitumumab to standard chemotherapy in a first-line setting in patients with stage IV NSCLC results in a statistically significant improvement in overall survival, while the results were not significant for progression-free survival and objective response rate.

e15756 Background: Preclinical studies have shown that calcium channel blockers (CCB) may potentiate anticancer effect of chemotherapy via intra-cellular drug accumulation. Gemcitabine-based chemotherapy is commonly used in pancreatic cancer (PC) patients. The aim of this study was to determine whether CCB may affect overall survival (OS) in PC patients receiving gemcitabine-based chemotherapy. Methods: The retrospective cohort of PC patients treated with gemcitabine between 2007 and 2016 was identified in the Polish National Health Fund databases. Electronic records of prescriptions were searched to identify in this cohort patients receiving CCB (amlodipine, nitrendipine, felodipine, lacidipine). The primary endpoint was OS and it was determined by Kaplan-Meier methods and compared by the log-rank test. Results: In total 4628 PC patients treated with gemcitabine (median OS 7.7 months; 95% CI: 7.4-7.9) were identified. Among these 380 patients were prescribed any CCB. There was a significant difference (p < 0.001) in median OS between patients prescribed CCB (n = 380; OS 9.3 months; 95% CI: 7.8-11.0) and those who did not (n = 4214; OS 7.6 months; 95% CI: 7.3-7.8) with hazard ratio for death 0.70 (95% CI: 0.62-0.79). Notably, the survival curves tended to flatten in CCB group, with 24% of patients alive at 2 years (95% CI: 20-29%) and 15% alive at 5 years (95% CI: 11-19%), compared with 11% (95% CI: 10-12%) and 4% (95% CI: 4-5%) in controls respectively. Conclusions: The use of CCB in PC patients receiving gemcitabine-based chemotherapy was associated with improved OS. Further validation is needed to evaluate effectiveness of CCB-gemcitabine combinations in the management of PC.

Early Tumor

749 Background: It was reported that early tumor shrinkage (ETS) was associated with better overall survival (OS) in patients (pts) with metastatic colorectal cancer (mCRC) receiving cetuximab. We investigated association of ETS with progression free survival (PFS) in pts with unresectable colorectal liver metastases (CLM) from HGCSG0802 observational cohort study in pts with mCRC treated with first-line bevacizumab (BV)-based chemotherapy. Methods: The objective of HGCSG0802 was to evaluate PFS, OS, time to treatment failure (TTF), response rate (RR), safety and so on. The key eligibility criteria were evaluable lesions, older than 20 years old, ECOG PS 0-2. In this analysis, association of ETS at 8 weeks from the start of chemotherapy with pts characteristics, PFS and TTF was evaluated. Pts characteristics were compared using Student-t test, chi-square test and Fisher’s exact test. PFS and TTF were analyzed with Kaplan-Meier method and compared using log-rank test. Univariate analysis for the association of pts characteristics with PFS and TTF was performed using log-rank test, and multivariate analysis was performed using Cox proportional hazards model. Results: Of 108 pts (the full analysis set), 74 pts with CLM were evaluable for ETS. Forty-nine pts (66.2%) had ETS ≥20%. The pts characteristics between ETS ≥20% and <20% were well balanced. The median PFS was 7.3 months in ETS <20% versus 10.0 months in ETS ≥20% (HR 0.55; p=0.025). In multivariate analysis for PFS, there was no significant difference between ETS ≥20% and <20% (HR 0.585; p=0.066). The median TTF (ETS <20% v ≥20%) was 5,1 months vs. 7.7 months (HR 0.46; p=0.003). In multivariate analysis for TTF, there was significant difference between ETS ≥20% and <20% (HR 0.509; p=0.017). Conclusions: In this analysis, ETS ≥20% might be positive predictive marker for PFS and TTF in pts with CLM receiving first-line BV-based chemotherapy.

The Difference

Purpose. This study retrospectively evaluated overall survival (OS) by treatment of recurrent or metastatic uterine adenosarcoma including surgery, radiation, chemotherapy, and hormonal therapy and evaluated OS and progression-free survival (PFS) after 1st line systemic chemotherapy. Methods. 78 patients with recurrent or metastatic adenosarcoma comprised the study population. The Kaplan-Meier method was used to estimate OS and PFS. The log-rank test was performed to test the difference in survival between groups. Results. Median OS from diagnosis of recurrent or metastatic disease was 1.8 yrs. OS was influenced by pathology on recurrence, p=0.035. Median OS differed by surgery for 1st recurrence 26.3 months versus 15.1 months. OS was not influenced by chemotherapy, p=0.58, palliative radiation, p=0.58, or hormonal therapy, p=0.15. The response rate (CR + PR) per RECIST 1.1 for chemotherapy was 31.2% for doxorubicin-based regimens and 14.3% for gemcitabine/docetaxel. OS since 1st line chemotherapy was not significantly different among chemotherapy regimens. However, the median PFS was superior for doxorubicin/ifosfamide (15.4 months) compared to gemcitabine/docetaxel (5.0 months), platinum-based regimens (5.7 mo), or other doxorubicin-based regimens (6.5 months). Conclusion. These results suggest that surgery is an important treatment modality for recurrent or metastatic uterine adenosarcoma, and the most effective chemotherapeutics are doxorubicin/ifosfamide and gemcitabine/docetaxel.

e14622 Background: Data from the Czech national registry of patients treated with targeted therapies for mCRC were analyzed retrospectively to compare treatment outcomes for bevacizumab in combination with chemotherapy in the 1st, 2nd and 3rd line of treatment. Methods: The database was launched in 2005 as a clinical registry of patients with mCRC treated with bevacizumab. Epidemiological and clinical data are entered by all Czech comprehensive cancer centers administering targeted therapy. In total, 4487 mCRC patients who received bevacizumab combined with chemotherapy in either 1st line (n=3990, 88.9%), 2nd line (n=386, 8.6%), or 3rd and higher line (n=111, 2.5%) had evaluable data and were included in the present analysis. Survival was calculated using the Kaplan-Meier method, and the differences were assessed using the log-rank test. Results: Statistically significant differences were observed in the efficacy of combination chemotherapy with bevacizumab between the treatment lines. The objective response rate (ORR) in the 1st, 2nd, and 3rd/higher line was 42.9%, 34.0% and 8.3%; (p<0.001) respectively. Similarly, in the 1st, 2nd, and 3rd/higher line median progression free survival (mPFS) was 11.3 months (95% CI 11.0-11.7 months), 9.5 months (95% CI 8.2-10.9 months) , and 7.3 months (95% CI 5.9-8.7 months; p<0.001), and median overall survival (mOS) was 28.4 months (95% CI 27.1-29.8 months), 25.9 months (95% CI 19.4-32.4 months), and 15.0 months (95% CI 10.7-19.3 months; p<0.001), respectively. The spectrum of the most common adverse events was comparable in the 1st, 2nd, or 3rd/higher line, and incidence of adverse events was similar at 11.6%, 8.8% and 8.1%, respectively. Conclusions: The efficacy of bevacizumab in combination with chemotherapy decreased when administered in later lines of treatment for mCRC while the incidence and spectrum of toxicities remains unchanged.

Necrosis Factor

Systemic release of tumor necrosis factor (TNF) and lymphotoxin-α (LTα) has been found to contribute to the severity of non-Hodgkin's lymphoma (NHL). We investigated whether genetic polymorphisms in the TNF locus, previously shown to influence TNF and LTα genes expression, might contribute to these cytokines production and to the clinical course of NHL. Genomic DNA from 273 lymphoma patients was typed for TNF (−308) polymorphism using an allele-specific polymerase chain reaction (PCR) and for LTα (+252) polymorphism with a PCR-based restriction fragment length polymorphism. The presence of the TNF allele involved in increased TNF gene transcription was associated with higher plasma levels of this cytokine at the time of lymphoma diagnosis (χ2 test, P = .013). An extended haplotype analysis showed that the presence of at least two TNF or LTα high-producer alleles constituted a risk factor for first-line treatment failure (χ2 test, P = .021), shorter progression-free survival (log-rank test, P = .0007), and overall survival (log-rank test, P = .012). In the subgroup of 126 patients with diffuse large-cell lymphoma, the presence of two or more TNF/LTα high producing alleles contributed significantly to a higher rate of relapse and progression (log-rank test, P = .045 and P = .027). In multivariate Cox regression models including the variables of the International Prognostic Index, the TNF/LTα haplotype status was found to be an independent risk factor for progression-free survival (relative risk 2.33, 95% confidence interval [1.17 to 4.64], P = .0053) and overall survival (relative risk 1.92, 95% confidence interval [0.63 to 5.80],P = .081) of large-cell lymphoma patients. These results indicate that genetic polymorphism leading to increased TNF production influences the outcome of NHL and suggest a pathophysiological role for the genetic control of the immune response in lymphoid malignancies.
