Methionine addiction is a fundamental and general hallmark of cancer caused by enhanced methyl flux. In the present study, we effected a novel methionine-methylation blockade to target a patient-derived orthotopic xenograft model of pancreatic cancer.

The pancreatic cancer patient-derived orthotopic xenograft mouse models were randomized into 6 groups of 8 mice each and treated for 2 weeks untreated control; azacitidine; oral recombinant methioninase (o-rMETase); o-rMETase plus cycloleucine; o-rMETase plus cycloleucine plus azacitidine (triple-methyl blockade therapy); and gemcitabine (positive control).

Triple-methyl blockade therapy arrested tumor growth (mean relative tumor volume, 1.03 [standard deviation, 0.36]) and was significantly more effective compared with azacitidine (P = 0.0001); o-rMETase (P = 0.007); or o-rMETase plus cycloleucine (P = 0.04). Gemcitabine alone also inhibited but did not arrest tumor growth (mean relative tumor volume, 1.50 [standard deviation, 0.30]). The percentage of cancer cells that were negative for 5-methylcytosine staining in immunohistochemistry, indicating reduction of DNA methylation, increased with triple-methyl blockade therapy (37.5%), compared with gemcitabine (1.8%); o-rMETase (2.8%); azacitidine (9.0%); or o-rMETase plus cycloleucine (10.6%).

This new concept of triple-methyl blockade therapy has clinical potential for pancreatic cancer, which is currently a recalcitrant disease.

The objective of this study was to characterize gut microbiome profiles of infants with congenital hyperinsulinism (HI) who underwent near-total or partial pancreatectomy for hypoglycemia management, as compared with healthy controls.

A prospective observational cohort study was performed. Subjects were infants (0-6 months) with HI who underwent removal of pancreatic tissue for management of intractable hypoglycemia from February 2017 to February 2018 at the Children's Hospital of Philadelphia. Fecal samples were collected postoperatively, on full enteral nutrition. The gut microbiome of HI subjects was analyzed and compared with age-matched samples from healthy infants.

Seven subjects with ≥50% pancreatectomy and 6 with <50% pancreatectomy were included. α (within-sample) diversity was lowest among infants with ≥50% pancreatectomy (richness false discovery rate, 0.003; Shannon index false discovery rate, 0.01). β (between-sample) diversity (Bray-Curtis dissimilarity, P = 0.02; Jaccard distance, P = 0.001) differed across groups (≥ or <50% pancreatectomy, controls). Bifidobacteria and Klebsiella species were least abundant among infants with ≥50% pancreatectomy but did not differ between infants with <50% pancreatectomy and historical controls.

Infants with HI who underwent ≥50% pancreatectomy differed from age-matched infants in gut microbiome profile, whereas those with <50% pancreatectomy more closely resembled control profiles. The durability of this difference should be investigated.

The combination of gemcitabine plus nab-paclitaxel (GnP) has not been studied in Japanese patients with resectable pancreatic cancer (PC). This study aimed to assess the tolerability of adjuvant GnP in Japanese patients with resected PC.

This was a Phase I, open-label, multicenter, single-arm study of patients with resected PC in Japan. Patients received 125 mg/m2 of nab-paclitaxel and 1000 mg/m2 of gemcitabine on days 1, 8, and 15 of a 28-day cycle for a total of 6 cycles. The primary end point was tolerability, defined as the absence of specific grade 3 or higher treatment-related adverse events by the end of cycle 2. Secondary end points included safety, disease-free survival, and overall survival.

Forty-one patients were enrolled between June 2016 and February 2017 (median age, 68 years; 51% male; stage II, 95%). Gemcitabine plus nab-paclitaxel met the tolerability criteria in 39 of the 40 patients included in the tolerability analysis set (97.5%). The most common treatment-related adverse events were leukopenia, neutropenia, alopecia, and peripheral sensory neuropathy. After a follow-up of 30.1 months, median disease-free survival was 17.0 months and median overall survival was not reached.

These results show that adjuvant GnP is tolerable in Japanese patients with resected PC.Clinical Trial Registration No. Hormones modulator JapicCTI-163179.

The aim of this multicenter retrospective study was to identify the optimal chemotherapeutic regimen for advanced pancreatic acinar cell carcinoma (PACC).

Fifty-eight patients with histopathologically confirmed advanced PACC who had received chemotherapy between 1996 and 2013 were enrolled. The clinical characteristics of the patients and the treatment efficacy data were collected from the medical records at 16 Japanese institutions, using standardized data collection instrument.

The most commonly selected treatment regimens were gemcitabine-, fluoropyrimidine-, platinum-, and irinotecan-containing regimens. The overall response rate in the patients who received first-line chemotherapy were 7% and 38%, respectively, and the median overall survival was 13.2 months. When the data for all the treatment lines were aggregated, the response rates to gemcitabine-, fluoropyrimidine-, platinum-, and irinotecan-containing regimens were 7%, 18%, 40%, and 29%, respectively. The overall survival tended to be better in patients who had received a platinum-containing regimen (hazard ratio, 0.50; 95% confidence interval, 0.23-1.11; P = 0.08) or irinotecan-containing regimen (hazard ratio, 0.42; 95% confidence interval, 0.15-1.19; P = 0.09) at least once in the treatment course as compared with those who had not.

Our findings suggested that platinum- and irinotecan-containing regimens exhibited some potential efficacy in patients with advanced PACC.
