476 Background: Gemcitabine-based chemotherapy is considered as a standard front-line treatment for patients with advanced pancreatic cancer. Although addition of erlotinib or S-1 to gemcitabine has yielded better outcomes, it has showed just modest improvement in survival. To overcome this limitation, we evaluated the efficacy and safety of the combination of gemcitabine, erlotinib, and S-1 for the treatment of advanced pancreatic cancer. Methods: Chemotherapy-naïve patients with pathologically proven locally advanced, recurrent or metastatic pancreatic adenocarcinoma were assessed for eligibility. Gemcitabine at 1,000 mg/m2 was administered intravenously on day 1, and 8, erlotinib at 100 mg/day was administered on day 1-21, and S-1 at 60 mg/m2 was administered on days 1-14 every 21 days and continued to maximum of 8 cycles of treatment. Dose escalation of S-1 to 80 mg/m2 was permitted from second cycle for pre-defined tolerable patients. Results: Thirty-seven patients (median age 61.5 years) were enrolled. A total of 140 cycles of chemotherapy were administered (median of 3.8; range 1–8 cycles). Toxicities were evaluated in 36 patients, and the responses were evaluated in 31 patients. Major grade 3/4 toxicities included neutropenia (25%), febrile neutropenia (2.8%), fatigue (22.2%), infection (8.3%), vomiting (5.6%), and mucositis (5.6%). The overall response rate was 12.9% [95% confidence interval (CI), 5.1-28.9%] and disease control rate was 74.2% (95% CI, 56.8-86.3%). The median progression-free survival and overall survival were 3.4 months (95 % CI, 2.3-4.5 months) and 5.7 months (95 % CI, 3.9-7.6 months), respectively. Conclusions: The combination of gemcitabine, erlotinib, and S-1 provided an acceptable toxicity profile and modest clinical benefits in patients with advanced pancreatic cancer. Clinical trial information: NCT01693419.

Aims and background To evaluate the efficacy and tolerability of a new treatment approach including induction chemotherapy (CT) and concurrent chemoradiotherapy (CRT) in unresectable, locally advanced pancreatic cancer (LAPC). Patients and methods Twenty-four patients with LAPC were enrolled in the study. They first received induction CT consisting of 5-fluorouracil (5FU) (500 mg/m2) and gemcitabine (1000 mg/m2), which were given weekly for 3 weeks of every 4. Patients showing a response or disease stabilization after 2 cycles of induction CT received CRT consisting of external beam radiotherapy (50.4-54 Gy in fractions of 1.8 Gy/day) and gemcitabine (350 mg/m2, weekly for 6 weeks). Patients without disease progression received 2 additional cycles of CT consisting of 5FU plus gemcitabine with the same doses and schedule as given in the induction CT. Results After the end of the study, 2 (8%) and 5 (21%) patients showed complete and partial responses, respectively. Five patients (21%) had disease stabilization. The grade 3 and 4 toxicities associated with CT were neutropenia (21%) and thrombocytopenia (4%). The grade 3 and 4 toxicities occurring in patients who received CRT were neutropenia (24%), thrombocytopenia (24%), diarrhea (18%), and nausea (12%). The median progression-free survival for all patients was 6 months (95% CI, 3.6-8.4), and the median overall survival was 11 months (95% CI, 8.16-13.84). Conclusions The CRT approach of this study is moderately active and has an acceptable toxicity profile. However, the incor-poration of combination CT into CRT at the present schedule could not produce any additional benefit over CRT alone. Newer agents with more systemic activity are clearly warranted.

Purpose Gemcitabine (Gem) is the standard treatment for advanced pancreatic cancer. Given the promising phase II results obtained with the Gem-oxaliplatin (GemOx) combination, we conducted a phase III study comparing GemOx with Gem alone in advanced pancreatic cancer. Patients and Methods Patients with advanced pancreatic cancer were stratified according to center, performance status, and type of disease (locally advanced v metastatic) and randomly assigned to either GemOx (gemcitabine 1 g/m2 as a 100-minute infusion on day 1 and oxaliplatin 100 mg/m2 as a 2-hour infusion on day 2 every 2 weeks) or Gem (gemcitabine 1 g/m2 as a weekly 30-minute infusion). Results Three hundred twenty-six patients were enrolled; 313 were eligible, and 157 and 156 were allocated to the GemOx and Gem arms, respectively. GemOx was superior to Gem in terms of response rate (26.8% v 17.3%, respectively; P = .04), progression-free survival (5.8 v 3.7 months, respectively; P = .04), and clinical benefit (38.2% v 26.9%, respectively; P = .03). Median overall survival (OS) for GemOx and Gem was 9.0 and 7.1 months, respectively (P = .13). GemOx was well tolerated overall, although a higher incidence of National Cancer Institute Common Toxicity Criteria grade 3 and 4 toxicity per patient was observed for platelets (14.0% for GemOx v 3.2% for Gem), vomiting (8.9% for GemOx v 3.2% for Gem), and neurosensory symptoms (19.1% for GemOx v 0% for Gem). Conclusion These results confirm the efficacy and safety of GemOx, but this study failed to demonstrate a statistically significant advantage in terms of OS compared with Gem. Because GemOx is the first combined treatment to be superior to Gem alone in terms of clinical benefit, this promising regimen deserves further development.

318 Background: To improve poor therapeutic outcome of current practice of chemoradiotherapy (CRT), high dose helical tomotherapy (HT) with concurrent full-dose chemotherapy has been performed on patients with locally advanced pancreatic cancer (LAPC), and the results were analyzed. Methods: We retrospectively reviewed 39 patients with LAPC treated with radiotherapy using HT (median, 58.4 Gy; range, 50.8-59.9 Gy) and concomitant chemotherapy between May 2006 and May 2009. Radiotherapy was directed to the primary tumor with a 0.5 cm margin without prophylactic nodal coverage. Twenty nine patients (79%) received full-dose (1000 mg/m2) gemcitabine based chemotherapy during HT. After completion of CRT, maintenance chemotherapy was administered to 37 patients (95%). Results: The median follow-up was 15.5 months (range 3.4-43.9) for the entire cohort, and 22.5 months (range 12.0-43.9) for surviving patients. The 1- and 2-year local progression-free survival rates were 82.1% and 77.3%, respectively. Eight patients (20%) were converted to resectable status, including one with a pathologic complete response. The median overall survival and progression-free survival were 21.2 and 14.0 months, respectively. Acute toxicities were acceptable with no gastrointestinal (GI) toxicity higher than grade 3. Severe late GI toxicity (≥ Grade 3) occurred in 10 patients (26%); one treatment related death due to GI bleeding was observed. Conclusions: High-dose helical tomotherapy with concurrent full-dose chemotherapy resulted in improved local control and long-term survival in patients with LAPC. Future studies are needed to widen the therapeutic window by minimizing late GI toxicity.

490 Background: Conroy et al. (N Engl J Med 364:1817–1825, 2011) have shown significantly better overall survival with FOLFIRINOX compared to gemcitabine in metastatic pancreatic cancer patients (MPC). However, given the toxicity associated with FOLFIRINOX treatment, different institutions have adapted varying modifications to the original regimen. Methods: We performed a retrospective review of dose, toxicity, and efficacy of FOLFIRINOX in patients with unresectable locally advanced pancreatic cancer (LAPC) and MPC treated between Jan 2011 and Dec 2015 at University of Vermont Medical Center. Results: 43 patients were treated, of which 33 did not receive any prior treatment (6 LAPC, 27 MPC). 41 patients received dose attenuation with 1st cycle. Median relative dose of irinotecan, oxaliplatin and 5-FU were less than reported by Conroy (69 vs. 81%, 70 vs. 78% and 71 vs. 82%). Median number of treatment cycles 7.8 (range 1 to 41). Median progression free survival in our MPC cases compared to Conroy’s data was 5.7 vs. 6.4 months; overall survival at 6 and 12 months were 78 vs. 75.9% and 41 vs. 48.4% respectively. Grade ¾ toxicities were less, including neutropenia (p<0.001), fatigue (p =0.01) and neuropathy (p=0.04). One patient had grade 3 pneumonitis related to oxaliplatin. Conclusions: Our findings suggest that dose attenuation of 5-FU, irinotecan and oxaliplatin improve tolerability with fairly similar outcome as reported by Conroy et al. [Table: see text]

Purpose TH-302 is an investigational hypoxia-activated prodrug that releases the DNA alkylator bromo-isophosphoramide mustard in hypoxic settings. This phase II study (NCT01144455) evaluated gemcitabine plus TH-302 in patients with previously untreated, locally advanced or metastatic pancreatic cancer. Patients and Methods Patients were randomly assigned 1:1:1 to gemcitabine (1,000 mg/m2), gemcitabine plus TH-302 240 mg/m2 (G+T240), or gemcitabine plus TH-302 340 mg/m2 (G+T340). Randomized crossover after progression on gemcitabine was allowed. The primary end point was progression-free survival (PFS). Secondary end points included overall survival (OS), tumor response, CA 19-9 response, and safety. Results Two hundred fourteen patients (77% with metastatic disease) were enrolled between June 2010 and July 2011. PFS was significantly longer with gemcitabine plus TH-302 (pooled combination arms) compared with gemcitabine alone (median PFS, 5.6 v 3.6 months, respectively; hazard ratio, 0.61; 95% CI, 0.43 to 0.87; P = .005; median PFS for metastatic disease, 5.1 v 3.4 months, respectively). Median PFS times for G+T240 and G+T340 were 5.6 and 6.0 months, respectively. Tumor response was 12%, 17%, and 26% in the gemcitabine, G+T240, and G+T340 arms, respectively (G+T340 v gemcitabine, P = .04). CA 19-9 decrease was greater with G+T340 versus gemcitabine (−5,398 v −549 U/mL, respectively; P = .008). Median OS times for gemcitabine, G+T240, and G+T340 were 6.9, 8.7, and 9.2 months, respectively (P = not significant). The most common adverse events (AEs) were fatigue, nausea, and peripheral edema (frequencies similar across arms). Skin and mucosal toxicities (2% grade 3) and myelosuppression (55% grade 3 or 4) were the most common TH-302–related AEs but were not associated with treatment discontinuation. Conclusion PFS, tumor response, and CA 19-9 response were significantly improved with G+TH-302. G+T340 is being investigated further in the phase III MAESTRO study (NCT01746979).

269 Background: TTFields are alternating electric fields delivered to the region of the tumor by means of non-invasive transducer arrays. TTFields interfere with mitotic spindle formation, thus having an anti-mitotic activity. In pancreatic cancer, TTFields decreased proliferation and clonogenic potential in vitro, and reduced tumor volume in vivo. The PANOVA trial was designed to test TTFields, combined with chemotherapy, in pancreatic cancer. Methods: Twenty patients with advanced pancreatic adenocarcinoma were enrolled in a prospective, single arm study of TTFields at 150 kHz, concomitant with standard weekly gemcitabine. All patients had histologically-confirmed unresectable tumors, with an ECOG performance score of 0-1 and no prior chemotherapy or radiation therapy. The primary endpoint was incidence and severity of treatment emergent adverse events (AEs). Secondary endpoints included progression free survival (PFS), PFS rate at 6 months, overall survival (OS) and response rate. Results: The median age was 73 (range – 49-81) and 60% of the patients were females. Most patients (80%) had an ECOG score of 1. Twelve patients (60%) had distant metastases, while the others had locally advanced disease. Median compliance with TTFields was 78% (14 hours/day), with median duration of 5 months. Fourteen patients (70%) had serious (grade 3-5) AEs during the study period. Six patients (30%) had hematological, 45% gastrointestinal and 15% pulmonary AEs. Ten patients (50%) had treatment-related skin toxicity, of which only 2 were grade 3, both resolved with appropriate treatment. No TTFields-related serious AEs were reported. The median PFS was 8.3 months (95% CI 4.3, 10.3). PFS rate at 6 months was 56%. Of the evaluable tumors, 30% had partial response and another 30% stable disease. The median OS was 14.9 months and 1-year survival rate was 55%. Conclusions: TTFields concomitant to gemcitabine are tolerable and safe for advanced pancreatic cancer patients. The efficacy results are promising and support further research in this indication. An extension of the PANOVA protocol, including 20 additional patients who receive gemcitabine, nab-paclitaxel and TTFields is ongoing. Clinical trial information: NCT01971281.

Critical Overview

Background: We performed a critical overview of published systematic reviews (SRs) of chemotherapy for advanced and locally advanced pancreatic cancer, and evaluated their quality using AMSTAR2 and ROBIS tools. Materials and Methods: PubMed and Cochrane Central Library were searched for SRs on 13th June 2020. SRs with metaanalysis which included only randomized controlled trials and that had assessed chemotherapy as one of the treatment arms were included. The outcome measures, which were looked into, were progression-free survival (PFS), overall survival (OS), and adverse events (AEs) of grade 3 or above. Two reviewers independently assessed all the SRs with both ROBIS and AMSTAR2. Results: Out of the 1,879 identified records, 26 SRs were included for the overview. Most SRs had concluded that gemcitabine-based combination regimes, prolonged OS and PFS, but increased the incidence of grade 3-4 toxicities, when compared to gemcitabine monotherapy, but survival benefits were not consistent when gemcitabine was combined with molecular targeted agents. As per ROBIS, 24/26 SRs had high risk of bias, with only 1/26 SR having low risk of bias. As per AMSTAR2, 25/26 SRs had critically low, and 1/26 SR had low, confidence in the results. The study which scored ‘low’ risk of bias in ROBIS scored ‘low confidence in results’ in AMSTAR2. The inter-rater reliability for scoring the overall confidence in the SRs with AMSTAR2 and the overall domain in ROBIS was substantial; ROBIS: kappa=0.785, SEM=0.207, p<0.001; AMSTAR2: kappa=0.649, SEM=0.323, p<0.001. Conclusion: Gemcitabine-based combination regimens can prolong OS and PFS but also worsen AEs when compared to gemcitabine monotherapy. The included SRs have an overall low methodological quality and high risk of bias as per AMSTAR2 and ROBIS respectively.

Objective: This study aims to compare recurrence patterns and outcomes of biologically effective dose (BED10, α/β = 10) of 60–70 Gy with those of a BED10 >70 Gy for locally advanced pancreatic cancer (LAPC). Methods: Patients from three centers with a biopsy and a radiographically proven LAPC were retrospectively included and data were prospectively collected from June 2012 to June 2019. Radiotherapy was delivered by stereotactic body radiation therapy. Recurrences were categorized as in-field, marginal, and outside-the-field recurrence. Patients in two groups were required to receive abdominal enhanced contrast CT or MRI every 2–3 months and CA19-9 examinations every month during follow-up. Treatment-related toxicities were evaluated every month. Overall survival (OS) and progression-free survival (PFS) were estimated using the Kaplan–Meier method. Results: After propensity score matching, there were 486 patients in each group. The median prescription dose of the two groups was 37 Gy/5–8 f (range: 36–40.8 Gy/5–8 f) and 42 Gy/5–8 f (range: 40–49.6 Gy/5–8 f), respectively. The median OS of patients with a BED10 >70 Gy and a BED10 60–70 Gy was 20.3 months (95% CI: 19.1–21.5 months) and 18.2 months (95% CI: 17.8–18.6 months) respectively ( p < 0.001). The median PFS of the two cohorts was 15.4 months (95% CI: 14.2–16.6 months) and 13.3 months (95% CI: 12.9–13.7 months) respectively ( p < 0.001). A higher incidence of in-field and marginal recurrence was found in patients with BED10 of 60–70 Gy (in-field: 97/486 versus 72/486, p = 0.034; marginal: 109/486 versus 84/486, p = 0.044). However, more patients with BED10 >70 Gy had grade 2 or 3 acute (87/486 versus 64/486, p = 0.042) and late gastrointestinal toxicities (77/486 versus 55/486, p = 0.039) than those with BED10 of 60–70 Gy. Conclusion: BED10 >70 Gy was found to have the best survival benefits along with a higher incidence of acute and late gastrointestinal toxicities. Therefore, a higher dose may be required in the case of patients’ good tolerance.

<b><i>Introduction:</i></b> Patients with advanced pancreatic cancer have a poor prognosis. FOLFIRINOX (FFX) and gemcitabine plus nab-paclitaxel (GnP) have been established as first-line treatment, but they have not been confirmed as second-line treatment after FFX. The aim of this study was to evaluate the safety and efficacy of GnP as second-line therapy after FFX in patients with unresectable pancreatic cancer. <b><i>Methods:</i></b> Twenty-five patients with unresectable pancreatic cancer were enrolled. The patients were treated with GnP after FFX between September 2015 and September 2019. Tumor response, progression-free survival (PFS), overall survival (OS), and incidence of adverse events were evaluated. <b><i>Results:</i></b> The response rate, disease control rate, median PFS, and median OS were 12%, 96%, 5.3 months, and 15.6 months, respectively. The common grade 3 or 4 adverse events were neutropenia (76%) and anemia (16%). <b><i>Conclusions:</i></b> GnP after FOLFIRINOX is expected to be one of the second-line recommendations for patients with unresectable pancreatic cancer.
