Abstract Background Undifferentiated carcinoma (UC) of the pancreas is a rare subtype of pancreatic cancer. Although UC has been considered a highly aggressive malignancy, no clinical studies have addressed the efficacy of chemotherapy for unresectable UC. Therefore, we conducted multicenter retrospective study to investigate the efficacy of chemotherapy in patients with UC of the pancreas. Methods This multicenter retrospective cohort study was conducted at 17 institutions in Japan between January 2007 and December 2017. A total of 50 patients treated with chemotherapy were analyzed. Results The median overall survival (OS) in UC patients treated with chemotherapy was 4.08 months. The details of first-line chemotherapy were as follows: gemcitabine (n = 24), S-1 (n = 12), gemcitabine plus nab-paclitaxel (n = 6), and other treatment (n = 8). The median progression-free survival (PFS) was 1.61 months in the gemcitabine group, 2.96 months in the S-1 group, and 4.60 months in the gemcitabine plus nab-paclitaxel group. Gemcitabine plus nab-paclitaxel significantly improved PFS compared with gemcitabine (p = 0.014). The objective response rate (ORR) was 4.2% in the gemcitabine group, 0.0% in the S-1 group, and 33.3% in the gemcitabine plus nab-paclitaxel group. Gemcitabine plus nab-paclitaxel also showed a significantly higher ORR compared with both gemcitabine and S-1 (gemcitabine plus nab-paclitaxel vs. gemcitabine: p = 0.033; gemcitabine plus nab-paclitaxel vs. S-1: p = 0.034). A paclitaxel-containing first-line regimen significantly improved OS compared with a non-paclitaxel-containing regimen (6.94 months vs. 3.75 months, respectively; p = 0.041). After adjustment, use of a paclitaxel-containing regimen in any line was still an independent predictor of OS (hazard ratio for OS, 0.221; 95% confidence interval, 0.076–0.647; p = 0.006) in multiple imputation by chained equation. Conclusions The results of the present study indicate that a paclitaxel-containing regimen would offer relatively longer survival, and it is considered a reasonable option for treating patients with unresectable UC.

Abstract Background To examine the effect of prior use of cetuximab and neck dissection on the effectiveness of nivolumab, we conducted a large-scale subgroup analysis in Japanese patients with recurrent/metastatic head and neck cancer. Methods Data on the effectiveness of nivolumab were extracted from patient medical records. All patients were analyzed for effectiveness by prior cetuximab use. In the analyses for prior neck dissection, only patients with locally advanced disease were included. Results Of 256 patients analyzed, 155 had received prior cetuximab. Nineteen of 50 patients with local recurrence underwent neck dissection. The objective response rate was 14.7 vs 17.2% (p = 0.6116), median progression-free survival was 2.0 vs 3.1 months (p = 0.0261), and median overall survival was 8.4 vs 12 months (p = 0.0548) with vs without prior cetuximab use, respectively. The objective response rate was 23.1 vs 25.9% (p = 0.8455), median progression-free survival was 1.8 vs 3.0 months (p = 0.6650), and median overall survival was 9.1 vs 9.9 months (p = 0.5289) with vs without neck dissection, respectively. Conclusions These findings support the use of nivolumab for patients with recurrent/metastatic head and neck cancer regardless of prior cetuximab use or neck dissection history.

Five electronic databases were searched for eligible records. Outcomes were presented and analyzed according to the objective response rate (ORR), progression-free survival (PFS) rate, and overall survival (OS) rate. Five records involving 2,024 participants were included in the study. The pooled analysis of OS and PFS were longer with ramucirumab (RAM) therapy than without RAM for OS (odds ratio OR = 0.90 , 95% confidence interval CI = 0.82 – 1.00 , p = 0.05 ) and PFS ( OR = 0.74 , 95 % CI = 0.57 – 0.96 , p = 0.02 ). Moreover, compared with the current first-line chemotherapy, the OS ( OR = 0.93 , 95 % CI = 0.83 – 1.04 , p = 0.19 ) and PFS ( OR = 0.82 , 95 % CI = 0.64 – 1.06 , p = 0.13 ) results were not significantly higher with RAM. The ORRs of the patients in the RAM therapy groups were significantly higher than those in the groups without RAM ( OR = 1.40 , 95 % CI = 1.14 – 1.73 , p = 0.001 ).

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.

The Impact

9049 Background: Correlations between overall survival (OS) and objective response rate (ORR) or progression-free survival (PFS) are poor. We aimed to evaluate the impact of crossover and unbalanced subsequent treatments on ORR and PFS as surrogate endpoints for OS in patients with advanced NSCLC receiving first-line therapy. Methods: A systematic literature review of randomized clinical trials of systemic treatment for patients with stage IIIB/IV NSCLC receiving first-line therapy was performed. Weighted (by trial size) linear regression models were fitted with the absolute difference in ORR or median PFS as an independent variable and the absolute difference in median OS as a dependent variable. The analysis was repeated in predefined subsets based on crossover and balance of post-progression therapies. Surrogate threshold effect (STE) was estimated using prediction intervals. Results: 317 trials (78,644 patients) fulfilled the eligibility criteria. In all treatment arms, the mean ORR, median PFS, and median OS were 28.2% (standard deviation (SD) = 12.4%), 5.1 months (SD = 2.1), and 10.4 months (SD = 2.5), respectively. ORR and PFS had weak (R = 0.351; 95% CI: 0.251-0.443) and (R = 0.397; 95% CI: 0.267-0.512) associations with OS, respectively. However, within phase III trials that did not allow crossover and reported balanced post-progression treatments, both ORR and PFS had stronger associations with OS (ORR and OS: R = 0.601, 95% CI: 0.399-0.747; PFS and OS: R = 0.695, 95% CI: 0.446-0.844). STE estimation indicated that trials that show statistically significant treatment effect size of ≥43% ORR or ≥3.2 median PFS months can be expected to show significant OS benefit with sufficient certainty. Conclusions: Surrogacy of ORR and PFS for OS might be better estimated in trials that do not allow crossover and report balanced post-progression treatments. Presented STE calculation can be used to estimate the expected effect on OS when either ORR or PFS are used as primary endpoints.

IntroductionAcral melanoma (AM) has different biological characteristics from cutaneous melanoma. Although systemic therapeutic strategies for advanced AM resemble those for advanced cutaneous melanoma, the evidence of the clinical use of immune checkpoint inhibitors (ICIs) for AM is still inadequate. We aimed to systematically analyze the therapeutic effects and safety profile of ICI treatments in advanced AM.MethodsThis systematic review was conducted in line with a previously registered protocol. Three electronic databases, conference abstracts, clinical trial registers, and reference lists of included articles were searched for eligible studies. The primary outcomes were therapeutic effects, and the secondary outcomes were the safety profiles.ResultsThis systematic review included six studies investigating anti-CTLA-4 immunotherapy, 12 studies investigating anti-PD-1 immunotherapy, one study investigating the combination therapy of anti-CTLA-4 and anti-PD-1, and one study investigating anti-PD-1 immunotherapy in combination with radiotherapy. In most studies investigating ipilimumab, the anti-CTLA-4 antibody, the objective response rate ranged from 11.4 to 25%, the median progression-free survival ranged from 2.1 to 6.7 months, and the median overall survival was more than 7.16 months. For studies discussing anti-PD-1 immunotherapy with nivolumab, pembrolizumab, or JS001, the objective response rate ranged from 14 to 42.9%, the median progression-free survival ranged from 3.2 to 9.2 months, and the median overall survival was more than 14 months. The combination therapy of anti-CTLA-4 and anti-PD-1 immunotherapy showed better efficacy with an objective response rate of 42.9% than single-agent therapy. The retrospective study investigating the combination therapy of anti-PD-1 immunotherapy and radiation showed no overall response. Few outcomes regarding safety were reported in the included studies.ConclusionsICIs, especially anti-CTLA-4 monoclonal antibodies combined with anti-PD-1 antibodies, are effective systematic treatments in advanced AM. However, there remains a lack of high-level evidence to verify their efficacy and safety and support their clinical application.

438 Background: Personalized medicine is a challenge for current oncology practice. Nowadays there are no pharmacoeconomic analyses in Spain dealing with the clinical and financial impact secondary to K-Ras based decisions for first-line therapy in mCRC patients. So, this study was aimed to assess the cost- effectiveness of K-Ras status based decisions in first- line therapy of mCRC patients in comparison with non- K-Ras based selection of available therapies. Methods: K-Ras mutation prevalence and efficacy of available therapies (measured as response rate and progression free survival) were extracted from randomized clinical trials (RCT) that allowed on-label use of accessible drugs in Spain. Then, we have simulated all possibilities of combination therapies for first-line mCRC based on K-Ras status (wild- type vs mutated) and confronted with all therapies that could be chosen in absence of K-Ras analysis. Prices for all drugs in Spain were used to assume the best- value for each drug including all possibilities to reduce pharmacy costs. For first line, median duration of therapy reported by RCT was used to calculate the final budget. 70 kg and 1.7 m were used as reference for patients dose calculations. Results: First-line therapy that includes a biological drug in absence of K-Ras status based decisions implies an incremental cost per 1% of increased response rate of 1,237 euros for irinotecan based doublets and 3,193 euros for oxaliplatin based doublets. On the opposite, K-Ras based decisions reduce costs per objective response by 69% and 35% for irinotecan and oxaliplatin- based schedules in K-Ras wild-type population incorporating cetuximab as biological agent. These data mimic all calculi based on incremental costs secondary to improved progression free survival measured as HR when all scenarios without prior determination of K-Ras status were confronted with K-Ras based decisions. Conclusions: K-Ras based decisions reduces costs per objective response as well as per improved progression free survival. The most cost- effective scenario among all simulated was cetuximab in combination with chemotherapy for patients that harbor wt K-Ras mCRC.

Aim: To evaluate how efficacy outcomes from real-world data (RWD) can support those from randomized controlled trials (RCTs), in the context of first-line tyrosine kinase inhibitor treatment of metastatic renal cell carcinoma. Patients & methods: PubMed, Ovid, MEDLINE and EMBASE were searched for RCTs and RWD studies with ≥50 adult patients per arm published in 2000–2017. Outcome measures were median progression-free survival, median overall survival and objective response rate. Results: A total of 13 RCTs and 22 RWD studies met eligibility criteria; 31, 28 and 25 studies, respectively, reported median progression-free survival, median overall survival and objective response rate. Summary outcome measures were similar in RWD and RCTs. Conclusion: RWD validates efficacy-based outcomes from RCTs and may provide supportive evidence to inform clinical decisions.

Background and ObjectivesThis study aimed to compare the efficacy of transarterial chemoembolization (TACE) plus sorafenib (TACE-S) to TACE plus lenvatinib (TACE-L) for the treatment of HCC with portal vein tumor thrombus (PVTT).MethodsThis cohort study recruited patients from September 2017 to September 2020. A total of 59 and 57 consecutive patients were treated with TACE-L and TACE-S, respectively.ResultsBefore propensity score matching (PSM), comparing TACE-L to TACE-S, the median overall survival (OS) time was 16.4 months and 12.7 months, respectively [hazard ratio (HR) 1.34; 95% confidence interval (CI): 0.81–2.20; p = 0.25]. The median progression-free survival (PFS) time was 8.4 months and 7.43 months, respectively (HR 1.54; 95% CI: 0.98–2.41; p = 0.081). After PSM, the median OS time was 18.97 months and 10.77 months, respectively (HR 2.21; 95% CI: 1.12–4.38; p = 0.022); the median PFS time was 10.6 months (95% CI: 6.6–18.0 months) and 5.4 months (95% CI: 4.2–8.1 months), respectively (HR 2.62; 95% CI: 1.43–4.80; p = 0.002). After PSM, the overall response rate (ORR) was 66.8% vs. 33.3% [odds ratio (OR) 0.85; 1.05–6.90; p = 0.037].ConclusionBoth TACE-L and TACE-S are safe, well-tolerated treatments for HCC with PVTT. In HCC with PVTT, TACE-L was significantly superior to TACE-S with respect to OS, PFS, and ORR. A larger-scale randomized clinical trial is needed.
