RESUMEN
AIM: Drug-induced interstitial lung disease (DI-ILD) is a serious adverse event during chemotherapy. This study aimed to obtain real-world data of the incidence, clinical characteristics, predictive factors, and prognosis of patients with pancreatic cancer who developed DI-ILD. METHODS: In patients with locally advanced or metastatic pancreatic cancer who underwent standard chemotherapy at our hospital and its participating facilities between April 2014 and March 2019, the clinical features, occurrence rate and clinical course of DI-ILD, and prognosis were retrospectively evaluated. RESULTS: Altogether, 390 patients were finally enrolled. DI-ILD occurred in 24 cases (6.2%). The median period from diagnosis of pancreatic cancer to the onset of DI-ILD was 2.2 months (.6-13.3 months). The rate of DI-ILD onset according to each regimen was 5.8% of gemcitabine (GEM) plus albumin-bound paclitaxel therapy (18/308), 3.8% of GEM (4/106), and 2.3% of FOLFIRINOX (2/88). The incidence of DI-ILD in GEM-based regimens was significantly higher than that in non-GEM-based regimens (p < .01). The median overall survival (OS) of the patients with and without DI-ILD after propensity score matching was 11.5 months and 11.4 months (p = .99), respectively. After the resolution of DI-ILD, no statistical significance in the median OS of the patients with and without subsequent treatment (11.0 vs. 6.8 months, p = .18) was observed. CONCLUSION: DI-ILD is not a rare adverse event in the current standard chemotherapy for pancreatic cancer in Japan. With appropriate management of DI-ILD, the prognosis of patients with DI-ILD can be equivalent to that of patients without DI-ILD.

Background: Endoscopic ultrasound-guided transluminal drainage (EUS-TD) is generally performed 4 weeks after disease onset for evacuating pancreatic fluid collections. However, the optimal timing for conducting the procedure in those diagnosed with postoperative pancreatic fistula (POPF) has not been established. We aimed to elucidate the efficacy and safety of early EUS-TD procedures for treating POPF. Methods: We retrospectively reviewed patients diagnosed with POPF who underwent EUS-TD in the Kyushu University Hospital between 2008 and 2019. Clinical features were comparatively analyzed between the two patient groups who underwent either early (≤15 days postoperatively) or late (>15 days postoperatively) EUS-TD. Factors prolonging hospital stay were also analyzed using Cox proportional hazard models. Results: Thirty patients (median age, 64.5 years) were enrolled. The most common initial operation was distal pancreatectomy with splenectomy (60.0%). Median size of POPF was 69.5 (range, 38-145) mm, and median time interval between surgery and EUS-TD was 17.5 (range, 3-232) days. Totally, 47% patients underwent early EUS-TD. Rates of technical success, clinical success, and complications were 100%, 97%, and 6.9%, respectively. No recurrence of POPF occurred during a median follow-up period of 14 months. Clinical characteristics and outcomes were comparable between the early and late drainage patient groups, except for the rates of infection and nonencapsulation of POPF, which were significantly higher in the early drainage group. Performing simultaneous internal and external drainage (hazard ratio (HR): 0.31; 95% confidence interval (CI): 0.11-0.93, p=0.04) and conducting ≥2 treatment sessions (HR: 0.26; 95% CI: 0.08-0.84, p=0.02) were significantly associated with prolonged hospitalization after EUS-TD. Conclusions: EUS-TD is a safe and effective method for managing POPF, regardless of when it is performed in the postoperative period. Once infected POPF occurs, clinicians should not hesitate to perform EUS-TD even within 15 days of the initial operation.

BACKGROUND/OBJECTIVES: This single-center study aimed to evaluate treatment outcomes and long-term prognosis of patients with pancreatic neuroendocrine neoplasms (PanNENs) based on the World Health Organization (WHO) 2017 classification. METHODS: We enrolled 245 patients with PanNENs treated at Kyushu University Hospital between January 1987 and March 2018. PanNENs were categorized according to the WHO 2017 classification or further subdivisions of Ki-67 index. Clinicopathological features, median survival time (MST), and prognostic factors were retrospectively analyzed. RESULTS: The number of PanNENs, especially non-functioning PanNENs, has increased over the last decade. The mean MST of all patients was 202 months; which was longest in patients with NET G1 (n = 145, MST = 261 months) relative to NET G2 (n = 72, 132 months), NET G3 (n = 3, 34 months) and NEC G3 (n = 17, 9 months). Prognosis in patients with surgery as the first-line treatment was significantly better than in those with drug therapy. However, 26% of patients who underwent curative resection developed recurrence after a median time of 28.7 months. In unresectable PanNENs (n = 97), the MST and 5-year survival rate were 78 months and 55.8%, respectively. Poor differentiation, Ki-67 index of >10% and presence of liver metastasis were significant unfavorable predictors. Response to first-line therapy (stable disease/partial response) and three or more treatment regimens were significant favorable predictors for unresectable PanNENs according to multivariate analyses (p < 0.01). CONCLUSIONS: We demonstrated the utility of the WHO 2017 classification for PanNENs in the real clinical setting. For better prognosis in PanNENs, the use of three or more regimens should be considered.

Although the postoperative recurrence rate for pancreatic neuroendocrine tumors (PNETs) is reported to be 13.5%-30%, the paucity of valuable biomarkers to predict recurrence poses a problem for the early detection of relapse. Hence, this study aimed to identify new biomarkers to predict the recurrence of PNETs. We performed RNA sequencing (RNA-Seq) on RNA isolated from frozen primary tumors sampled from all localized G1/G2 PNETs resected curatively from 1998 to 2015 in our institution. We calculated differentially expressed genes (DEGs) in tumor with and without recurrence (≥3 years) for the propensity-matched cohort. Gene ontology analysis for the identified DEGs was also performed. Furthermore, we evaluated the expression levels of candidate genes as recurrence predictors via immunostaining. Comparison of transcriptional levels in tumors with and without recurrence identified 166 DEGs. Up- and downregulated genes with high significance in these tumors were mainly related to extracellular organization and cell adhesion, respectively. We observed the top three upregulated genes, C-type lectin domain family 3 member A (CLEC3A), matrix metalloproteinase-7 (MMP7), and lipocalin2 (LCN2) immunohistochemically and compared their levels in recurrent and nonrecurrent tumors. Significantly higher recurrence rate was shown in patients with positive expression of CLEC3A (P = 0.028), MMP7 (P = 0.003), and LCN2 (P = 0.040) than that with negative expression. We identified CLEC3A, MMP7, and LCN2 known to be associated with the phosphatidylinositol-3-kinase/Akt pathway, as potential novel markers to predict the postoperative recurrence of PNETs.

For elderly people who are difficult to operate, percutaneous transhepatic gallbladder drainage (PTGBD) is conducted instead. In PTGBD, the bile is drained externally and impaired absorption of fat is a concern. Egg yolk lecithin, which is a fat emulsifier, is not easily broken in emulsion even under a low-pH condition, and the emulsified state is stable. Even in bile duct ligation rats, the emulsifier in egg yolk lecithin emulsion is reported to be superior to lipid absorption using other emulsifiers. Emulsification with egg yolk lecithin may possibly contribute to improvement of nutrition during biliary excretion disorders such as external drainage. We report a case of good progress with enteral nutrition with egg yolk lecithin-mixed liquid diet after PTGBD for acute cholecystitis. The patient was an 80-year-old man with a history of myocardial infarction and dementia. He was diagnosed with calculous cholecystitis, and conservative treatment was started. His cholecystitis was exacerbated, and PTGBD was performed on day 12 of the disease. On imaging, the lower extremities of the duodenum were edematous because of the spread of inflammation. Glutamine preparation alone was administered after resuming fasting. A liquid diet containing egg yolk lecithin, 200 ml of K-LEC (1 kcal/ml), was started from day 23, and was administered three times daily. Liquid diet dose was increased to 1,200 kcal/day with added dietary fiber on day 29. The patient's overall condition improved, and transthyretin level and body weight increased. Thereafter, after swallowing training, the patient was switched to oral meal intake from day 37.

Objective The selective arterial secretagogue injection (SASI) test is considered indispensable for the accurate localization of insulinoma. However, the optimum timing of the post-injection evaluation is controversial, as some studies recommend 60 seconds [SASI (60 seconds)] while others support 120 seconds [SASI (120 seconds)]. The aim of this study was to determine the optimum timing for the SASI test evaluation for insulinoma localization. Methods Thirteen patients with surgically proven insulinoma were studied retrospectively. For the SASI test, immunoreactive insulin (IRI) was determined at baseline and at 30, 60, 90, and 120 seconds after calcium gluconate injection. A two-fold or greater increase in IRI over the baseline value was considered positive. The localization abilities of SASI (60 seconds) and SASI (120 seconds) were then compared. Results In 13 patients, a secretagogue was injected into 40 arteries supplying the pancreas. In the SASI (60 seconds) and SASI (120 seconds), the respective findings were as follows: positive predictive value, 72.2% and 68.2%; false positive rate, 25.0% and 35.0%; and rate of positivity in the head and body/tail, 38.5% and 46.2%. When the artery with the largest change was taken as the dominant artery, the localization detection sensitivity was 76.9% for SASI (60 seconds) and 92.3% for SASI (120 seconds). The sensitivity of morphological imaging techniques for localization ranged from 61.5-91.7%. Conclusion Compared with SASI (60 seconds) or morphological imaging, the insulinoma localization ability of SASI (120 seconds) was superior. Given these findings, we believe that the IRI level should be measured at 120 seconds in the SASI test.

OBJECTIVES: To evaluate the utility of serum Wisteria floribunda agglutinin-positive Mac-2 binding protein (WFA + -M2BP) level as a marker for chronic pancreatitis (CP). METHODS: We measured the serum WFA+ -M2BP level of 74 patients with CP who had undergone endoscopic retrograde cholangiopancreatography and 30 normal controls (NC) using a glycan sugar chain-based immunoassay and investigated the relationship between serum WFA+ -M2BP levels and the Cambridge classification of CP. RESULTS: Serum WFA+ -M2BP level was significantly higher in patients with CP than in NC (0.64 ± 0.28 vs 0.34 ± 0.25, P < 0.001). The levels (expressed as cut-off index) of WFA+ -M2BP for the classification of mild, moderate and marked CP were 0.44, 0.63 and 0.87, respectively. Thus, serum WFA+ -M2BP levels increased with increasing CP severity. With a cut-off value of 0.34, 0.59 and 0.61, the area under the receiver operating characteristic curve, sensitivity and specificity were 0.829, 91.9% and 63.3% for mild CP; 0.891, 81.8% and 85.0% for moderate CP; and 0.888, 92.0% and 74.7% for marked CP, respectively. Multivariate analysis revealed that elevated serum WFA+ -M2BP was independently associated with moderate and marked CP, respectively. CONCLUSION: Serum WFA+ -M2BP level is a useful marker for grading CP severity.

Endoscopic necrosectomy (EN) for walled-off pancreatic necrosis (WOPN) is less invasive than surgical treatment and has become the first choice for pancreatic abscess. EN is usually carried out with several devices including snares, baskets, and grasping forceps. Occasionally, we have encountered cases in which EN has not been satisfactorily carried out, and there is pressure for further innovation in EN. Here, we describe a case of a large area of WOPN that was successfully treated by EN with endoscopic submucosal dissection and associated techniques, which facilitated removal of necrotic tissues. A 60-year-old man was referred to our hospital for WOPN as a complication of necrotizing pancreatitis. As a result of his complicating conditions including ischemic heart disease, uncontrollable arrhythmia, chronic renal failure, and persistent pleural effusion, he was deemed a poor surgical candidate. Although EN with conventional devices was carried out for five sessions, we could not remove the dense and massive necrotic tissues. At the sixth EN session, the Clutch Cutter device (Fujifilm, Tokyo, Japan) was used to remove the necrotic tissues, without major complications. This is believed to be the first report of EN using the Clutch Cutter for successful treatment of WOPN.
