Due to their inhibitory effects on hormone secretion, somatostatin analogues are of pivotal importance in the symptomatic treatment of hormone-secreting neuroendocrine tumours. Although several earlier clinical observations supported the view that these biological agents are capable of inhibiting the growth of neuroendocrine tumours, the PROMID study published in 2009 was the first to confirm the inhibitory effect of octreotide on tumour growth and demonstrated the prolongation of progression free survival. These findings have been confirmed and extended by the most recent CLARINET trial with lanreotide published in 2014. Somatostatin analogues are capable of inhibiting tumour growth and stabilizing disease irrespective of the hormonal activity of the tumour and, therefore, their applicability is expected to be extended to the treatment of hormonally inactive neuroendocrine tumours, as well.

We evaluated outcomes of treatment with 5-fluorouracil (5-FU), doxorubicin, and streptozocin (FAS) in well-differentiated pancreatic neuroendocrine tumors (PanNETs) and its impact on subsequent therapy (everolimus or temozolomide). Advanced PanNET patients treated at our center from 1992 to 2013 were retrospectively reviewed. Patients received bolus 5-FU (400 mg/m2), streptozocin (400 mg/m2) (both IV, days 1-5) and doxorubicin (40 mg/m2 IV, day 1) every 28 days. Overall response rate (ORR) was assessed using RECIST version 1.1. Of 243 eligible patients, 220 were evaluable for ORR, progression-free survival (PFS), and toxicity. Most (90%) had metastatic, nonfunctional PanNETs; 14% had prior therapy. ORR to FAS was 41% (95% confidence interval [CI]: 36-48%). Median follow-up was 61 months. Median PFS was 20 (95% CI: 15-23) months; median overall survival (OS) was 63 (95% CI: 60-71) months. Cox regression analyses suggested improvement with first-line vs subsequent lines of FAS therapy. Main adverse events ≥ grade 3 were neutropenia (10%) and nausea/vomiting (5.5%). Dose reductions were required in 32% of patients. Post-FAS everolimus (n=108; 68% second line) had a median PFS of 10 (95% CI: 8-14) months. Post-FAS temozolomide (n=60; 53% > fourth line) had an ORR of 13% and median PFS of 5.2 (95% CI: 4-12) months. In this largest reported cohort of PanNETs treated with chemotherapy, FAS demonstrated activity without significant safety concerns. FAS did not appear to affect subsequent PFS with everolimus; this sequence is being evaluated prospectively. Responses were noted with subsequent temozolomide-based regimens although PFS was possibly limited by line of therapy.

A rechallenge is common after initial efficacy of alkylating-based chemotherapy (ALK) in pancreatic neuroendocrine tumors (PanNET). High MGMT expression seems associated with lower response to ALK. We aimed to evaluate the efficacy and toxicity of ALK rechallenge in PanNET. Secondly, to assess the evolution of MGMT expression under ALK. All consecutive patients with advanced PanNETs who received initial ALK (achieving tumor control) followed by a pause > 3 months, then an ALK rechallenge (ALK2) upon progression were retrospectively studied (Cohort A). Primary endpoint was progression-free survival under ALK2 (PFS2). The MGMT expression was retrospectively assessed by immunohistochemistry (H-score) in consecutive PanNET surgically resected following ALK (Cohort B). We foud that cohort A included 62 patients (median Ki67 8%), for which ALK1 followed by pause achieved an objective response rate of 55%, and a PFS1 of 23.7 months (95% IC, 19.8-27.6). ALK2 achieved no objective response, and stability in 62% of patients. The median PFS2 was 9.2 months (IC 95% 7.1-11.3). At multivariable analysis, a hormonal syndrome (p=0.032) and a pause longer than 12 months (p=0.041) were associated with a longer PFS2. In the cohort B (17 patients), the median MGMT H-score increased from 45 (IQR 18-105) before ALK, to 100 (IQR 56-180) after ALK (p=0.003). We conclude that after initial efficacy of ALK treatment, a pause followed by ALK rechallenge might be appropriate to prolong tumor control, improve quality of life and limit long-term adverse events. Increased MGMT expression under ALK might explain low efficacy of ALK rechallenge.

Patients with lung adenocarcinoma harboring common epidermal growth factor receptor (EGFR) mutations usually have a good response rate (RR) and longer progression-free survival (PFS) to EGFR tyrosine kinase inhibitors (TKIs). However, the treatment efficacy to uncommon EGFR mutations remains controversial. We, therefore, performed a retrospective study, screening 2958 patients. A total of 67 patients with lung adenocarcinoma harboring uncommon EGFR mutations were enrolled and 57 patients with stage IV diseases receiving a first-line EGFR TKI were included for further analyses. The patients were classified into 27 (47%) “a single sensitizing uncommon mutation”, 7 (12%) “multiple sensitizing mutations”, 5 (9%) “a sensitizing mutation and a resistant uncommon mutation”, and 18 (32%) “other resistant uncommon mutations”. No significant difference was noted in PFS or overall survival (OS) between groups. Patients receiving different first-line EGFR TKIs had similar PFS and OS. The elder patients had a significantly poorer performance status than the younger patients but a significantly longer PFS than the younger patients (median PFS: 10.5 vs. 5.5 months, p = 0.0320). In conclusion, this is the first study to identify that elderly patients with stage IV lung adenocarcinoma harboring uncommon EGFR mutation might have a longer PFS. Large-scale prospective studies are mandatory to prove our findings.

Abstract Background: We compared outcomes and toxicities between concurrent retrograde super-selective intra-arterial chemoradiotherapy (IACRT) and concurrent systemic chemoradiotherapy (SCRT) for gingival carcinoma (GC). Methods: We included 84 consecutive patients who were treated for non-metastatic GC ≥ stage III, from 2006 to 2018, in this retrospective analysis (IACRT group: n=66; SCRT group: n=18).Results: The median follow-up time was 24 (range: 1–124) months. The median prescribed dose was 60 (6–70.2) Gy (IACRT: 60 Gy; SCRT: 69 Gy). There were significant differences between the two groups in terms of 3-year overall survival (OS; IACRT: 78.8%, 95% confidence interval [CI]: 66.0–87.6; SCRT: 50.4%, 95% CI: 27.6–73.0; P = 0.039), progression-free survival (PFS; IACRT: 75.6%, 95% CI: 62.7–85.2; SCRT: 42.0%, 95% CI: 17.7–70.9; P = 0.028) and local control rates (LC; IACRT: 77.2%, 95% CI: 64.2–86.4; SCRT: 42.0%, 95% CI: 17.7–70.9; P = 0.015). In univariate analysis, age ≥ 65 years, decreased performance status (PS) and SCRT were significantly associated with worse outcomes (P < 0.05). In multivariate analysis, age ≥ 65 years, clinical stage IV, and SCRT were significantly correlated with a poor OS rate (P < 0.05). Patients with poorer PS had a significantly worse PFS rate. Regarding acute toxicity, 22 IACRT patients had grade 4 lymphopenia, and osteoradionecrosis was the most common late toxicity in both groups.Conclusions: This is the first report to compare outcomes from IACRT and SCRT among patients with GC. ALL therapy related toxicities were manageable. IACRT is an effective and safe treatment for GC.

Abstract Purpose To assess and compare clinical outcomes and costs, to the Italian healthcare system, of three therapeutic options approved in the management of adult patients with gastro-enteropancreatic neuroendocrine tumours (GEP-NETs). Methods We compared the efficacy, safety and costs of [177Lu]Lu-DOTA-TATE, everolimus (both originator and generic products) and sunitinib in patients with advanced GEP-NETs (NET G1 and G2) that had progressed following treatment with somatostatin analogues (SSAs). A cost-consequence model was developed and validated by a panel of clinical experts from three NET reference centres in Italy. The clinical outcomes included in the model were median progression-free survival and the incidence of grade 3 or 4 adverse events (AEs), as reported in pivotal clinical trials. The costs for acquisition and administration of each treatment, and of managing AEs, were calculated from the perspective of the Italian national health service. Treatment costs per progression-free month were calculated separately for patients with NETs of pancreatic (PanNETs; all three treatments) and gastrointestinal (GI-NETs; [177Lu]Lu-DOTA-TATE and everolimus only) origin. Results In patients with PanNETs, total costs per progression-free month were €2989 for [177Lu]Lu-DOTA-TATE, €4975 for originator everolimus, €3472 for generic everolimus, and €5337 for sunitinib. In patients with GI-NETs, total costs per progression-free month were €3189 for [177Lu]Lu-DOTA-TATE, €4990 for originator everolimus, and €3483 for generic everolimus. Conclusions [177Lu]Lu-DOTA-TATE was associated with lower costs per progression-free month versus relevant treatment options in patients with GI-NETs or PanNETs (NET G1–G2; progressed following SSA treatment), although acquisition and administration costs are higher. These findings provide further economic arguments in the overall context of treatment decision making.

e21107 Background: C-Reactive Protein (CRP) is a non-specific inflammatory marker and reflects tissue destruction seen in metastatic cancer (ca). We have observed a tight correlation with CRP trends mirroring ca activity, hence it may prove to be a valuable marker to monitor response to Immuno-Oncology (IO) in non-small cell lung cancer (NSCLC) patients (pts). Once CRP levels stabilized, IO discontinuation was offered, and consenting pts were closely observed. This strategy resulted in shortened IO duration and impressive treatment-free progression-free survival (tf-PFS). We sought to examine the validity of this strategy using the rate of return to any form of ca therapy within 6 months after stopping IO. Methods: We analyzed all pts of a single provider since 2016 with stage IV NSCLC who had CRP checked while on IO, totaling 23 pts. We excluded pts who stopped IO for reasons besides stable CRP values (5 progressed on IO, 3 died while on IO, 1 had side effects, 1 stopped for a clinical trial, 1 opted to complete 2 years of IO, and 2 are still on IO). Of the remaining 10 patient cohort, all pts were males treated at the VA with ages between 56-75 years at diagnosis. 50% of the cohort had adenocarcinoma and 50% had squamous cell carcinoma. Results: Using the CRP trend to shorten the duration of IO resulted in durable drug-free holidays with none of the cohort returning to any form of ca therapy within 6 months and comparable rates of overall survival (OS) despite shorter IO duration. In KEYNOTE-042, the median OS for pts on the pembrolizumab arm was 16.7 months in the overall population and 20 months in the TPS ≥50% subgroup. Pts were treated for up to 35 months. In our cohort, median OS was 38 months, with all pts currently still alive, and median number of doses of IO was 9 cycles, or approximately 7 months. Our pts had ongoing progression free survival (PFS) after stopping treatment, which we report as tf-PFS. The median tf-PFS of our cohort was 23.5 months. Conclusions: In pts with stage IV NSCLC treated with IO, CRP appears promising as a marker to tailor IO therapy addressing tumor and clinical heterogeneity. Responding pts with stable CRP levels can be safely taken off IO. CRP should be monitored with stable values indicating continued PFS. tf-PFS rather than PFS may serve as a surrogate for cure and carries significant impact for pts financially, socially, and psychologically.
