Daisuke Shimizu, Kazushi Miyata, Masahide Fukaya, Shizuki Sugita, Tomoki Ebata

Anticancer research Vol. 43 ( 3 ) page： 1309 - 1315 2023.3

Language：English Publishing type：Research paper (scientific journal)

BACKGROUND/AIM: In patients with esophageal cancer, muscle loss induced by neoadjuvant therapy before esophagectomy is correlated with poor prognosis. However, little is known about the causes of muscle loss. Thus, the purpose of this retrospective study was to clarify the risk factors for muscle loss during neoadjuvant therapy. PATIENTS AND METHODS: Patients with esophageal cancer who underwent neoadjuvant therapy before esophagectomy between 2009 and 2020 were investigated (n=132). The patients received either cisplatin plus 5-fluorouracil (CF); docetaxel, cisplatin plus 5-fluorouracil (DCF); or CF with radiotherapy as neoadjuvant therapy. The cross-sectional areas of the bilateral psoas muscles were measured at the level of the third lumbar vertebra using CT, before and after neoadjuvant therapy, and psoas muscle loss was calculated. The patients were divided into the high muscle loss group with 5% or more muscle loss or the low muscle loss group with less than 5% loss. Correlations between muscle loss and clinical factors were evaluated. RESULTS: The median value of psoas muscle loss was 5.30%. Psoas muscle loss was significantly correlated with a poor 3-year overall survival rate (p=0.034). Multivariate analysis showed that the independent factors associated with muscle loss were age ≥70 years [odds ratio (OR)=2.43, p=0.022], treatment with DCF (OR=3.47, p=0.034), and a poor response to neoadjuvant therapy (OR=2.68, p=0.028). CONCLUSION: A regimen of DCF was a major trigger of muscle loss during neoadjuvant therapy.

BACKGROUND/AIM: α-Bisabolol is an essential oil component extracted from plants, such as chamomile. We have previously reported that α-bisabolol suppressed proliferation, invasion, and motility of pancreas cancer. Cyclodextrin improved the solubility of α-bisabolol, therefore it enabled to administer intravenously. The aim of this study was to clarify the effect of cyclodextrin conjugated α-bisabolol (CD-BSB) and the signals pathways associated with α-bisabolol for pancreatic cancer. MATERIALS AND METHODS: Human pancreatic cancer cell lines were treated with or without CD-BSB. Cytomorphology and apoptosis were assessed in these treated groups. In addition, several phosphorylated proteins were analyzed to clarify the signal pathway concerning CD-BSB. In subcutaneous xenograft model, tumor volume and Ki-67 expression were evaluated among Control (untreated), CD-BSB, or Gemcitabine (GEM). RESULTS: CD-BSB significantly changed cytomorphology and induced apoptosis in pancreatic cancer cells. CD-BSB suppressed phosphorylation of focal adhesion kinase (FAK). In addition, pFAK 397 was inhibited by CD-BSB in a concentration-dependent manner in cancer cells. In the subcutaneous xenograft models, the tumor volume in the CD-BSB groups was lower than Control groups. Ki67-positive cells in CD-BSB treated group were lower than the GEM-treated groups. CONCLUSION: We clarified the efficiency of CD-BSB in xenograft tumor using intravenous administration. α-Bisabolol suppresses phosphorylation of FAK 397 and impairs cytoskeletal polymerization in a pancreatic cancer cell line. Further investigations are required to reveal the precise mechanisms of the antitumor effects of solubilized α-bisabolol to facilitate its clinical application. Our data indicate that solubilized α-bisabolol has therapeutic potential and could improve the prognosis of cancer patients.

BACKGROUND/AIM: Deep ultraviolet (DUV) light spans within the 250 nm to 350 nm invisible wavelength range. Although it strongly damages various cells, the efficacy of DUV irradiation on pancreatic cancer cells has never been clarified. The purpose of this study was to reveal the antitumor effects of DUV irradiation on pancreatic cancer cells. MATERIALS AND METHODS: Human pancreatic cancer cell lines were eradicated with DUV or ultraviolet A (UVA) for 5 s. Several angiogenesis-related proteins were studied in cancer cells after DUV irradiation using a protein antibody array. A subcutaneous xenograft model was established by inoculation of pancreatic cancer cells into mice. Tumors in this model were irradiated with DUV or UVA once or twice for two weeks. Tumor volumes in these groups (DUV×1: one irradiation, DUV×2: two irradiations, and untreated) were analyzed one week after the second irradiation. RESULTS: DUV irradiation significantly changed the cytomorphology of pancreatic cancer cells. In addition, DUV irradiation induced apoptosis on pancreatic cancer cells more strongly than UVA irradiation and no irradiation. Interestingly, lower expression of thrombospondin 1 (TSP1) and tissue inhibitor of metalloproteinase 1 (TIMP1) was identified after DUV treatment. The tumor volume in the DUV-treated groups (DUV×1 and DUV×2) was smaller than that in the untreated group. CONCLUSION: Further investigations are required to reveal the precise mechanisms of the antitumor effects of DUV irradiation and to facilitate its clinical application as a new therapy for pancreatic cancer. Overall, DUV irradiation can be potentially used as a therapeutic option of pancreatic malignancy.

Correlation of Brain Metastasis Shrinking and Deviation During 10-Fraction Stereotactic Radiosurgery With Late Sequela: Suggesting Dose Ramification Between Tumor Eradication and Symptomatic Radionecrosis. International journal

Cureus Vol. 15 ( 1 ) page： e33411 2023.1

Language：English

Stereotactic radiosurgery (SRS) with >5 fraction (fr) has been increasingly adopted for brain metastases (BMs), given the current awareness of limited brain tolerance for ≤5 fr. The target volume/configuration change and/or deviation within the cranium during fractionated SRS can be unpredictable and critical uncertainties affecting treatment accuracy, plus the effect of these events on the long-term outcome remains uncertain. Herein, we describe a case of two challenging BMs treated by 10 fr SRS with a unique dose-gradient optimization strategy, in which the large cystic tumor revealed an intriguing correlation of such inter-fractional change with late radiographic sequela, suggesting a dose threshold for attaining long-term local tumor control and being immune to symptomatic brain necrosis. A 63-year-old man presented with two cystic lesions located in the left parietal lobe (19.9 cm3) and pons (1.1 cm3) one month after surgery for esophageal squamous cell carcinoma. The principles for 10 fr SRS were as follows: (1) very inhomogeneous gross tumor volume (GTV) dose covered by 53 Gy, biologically effective dose with an alpha/beta ratio of 10 (BED10) of ≥80 Gy; (2) moderate dose spillage margin outside the GTV boundary: 2-2.5 mm outside the GTV margin was covered by 37 Gy, BED10 of ≈50 Gy; (3) concentrically-laminated, steep dose increase inside the GTV boundary: 2 mm inside the GTV margin was covered by ≥62 Gy, BED10 of ≥100 Gy. At the completion of SRS, the parietal lesion showed significant shrinking and dorsomedial shifting with slight evisceration of the GTV, followed by marked regression of the parietal lesion within four months. At 13.5 months, a cystic change was noted at the dorsal part of the remnant. At 16.7 months, ventral enhancement gradually expanded without enlargement of the dorsal cystic component. On the T2-weighted images, the dorsal low-intensity remnant and ventral iso-intensity blurry-demarcated component were contrasting. Pathological examinations during and after lesionectomy at 17.4 months revealed necrosis only. At 30.5 months, the patient had a left visual field defect without recurrence. In contrast, the pons lesion showed no notable change during 10 fr SRS and nearly complete remission over six months with its sustainment without radiation injury at 30.5 months. Taken together, 10 fr SRS with a sufficient BED10 can provide superior tumor response and safety for BM that is not amenable to ≤5 fr SRS. Although a very inhomogeneous GTV dose can contribute to early and adequate tumor shrinkage and subsequent local tumor eradication, significant tumor shrinkage during fractionated SRS (fSRS) inevitably results in unnecessary higher dose exposure to the surrounding brain, which could lead to late radiation injury requiring intervention. The optimum dose should be determined through further investigation, in consideration of the dynamic and unpredictable nature of the actual absorbed doses to both the tumor and the surrounding brain.

Proposal for Shape Memory Alloy Positioning Actuator using Electric Parameter Based Controller

Miyata K., Kawazoe Y., Hara S.

IEEJ Journal of Industry Applications Vol. 12 ( 2 ) page： 153 - 154 2023

Publisher：IEEJ Journal of Industry Applications

This paper proposes the controller design for a shape memory alloy (SMA) positioning actuator system. The system utilizes spiral-formed SMA wire as the driving power source. SMA generates force via temperature-based crystalline phase transitions. The wire is deformed in the spiral form under low temperature and heated by applying direct current, it recovers to the original form and generates the recovering force, which rotates the attached load. This paper proposes using the electric resistance of the SMA, which is related to its crystalline phase status, for designing the controller of the actuator system. The feasibility of the proposed system and controller design are evaluated experimentally with a sample test device, manufactured using a 3D printer, and the device achieves the designed rotation.

Asia-Pacific journal of clinical oncology Vol. 18 ( 6 ) page： 578 - 585 2022.12

Language：English Publishing type：Research paper (scientific journal)

AIMS: The docetaxel and cisplatin plus 5-fluorouracil (5-FU) (DCF) regimen is expected to be superior to cisplatin plus 5-FU for the preoperative treatment of esophageal cancer. However, a high risk of adverse effects, including febrile neutropenia (FN), has been reported. To evaluate the effectiveness and safety of DCF with prophylactic pegfilgrastim, we conducted a phase II study. METHODS: The regimen consisted of intravenous administration of docetaxel (70 mg/m2 per day) and cisplatin (70 mg/m2 per day) on day 1 and a continuous infusion of 5-FU (750 mg/m2 per day) on days 1-5. A single 3.6-mg dose of pegfilgrastim was given as a subcutaneous injection on day 7 of each cycle. This regimen was repeated every 3 weeks for a maximum of three cycles. The primary endpoint was the grade-2/3 histopathological response rate. RESULTS: Thirty-seven eligible patients were enrolled and received DCF. Thirty-four patients underwent esophagectomy. Two patients received chemoradiotherapy or radiotherapy without surgery. One patient withdrew consent and ended his hospital visit. One patient received additional radiotherapy before surgery. Histopathological responses of grade 3, grade 2, grade 1b, and grade 1a were observed in two (5.4%), 14 (37.8%), 10 (27.0%), and seven (18.9%) patients, respectively, and the primary endpoint was met. Of the 37 eligible patients, 11 (29.7%) developed FN in the first cycle. CONCLUSIONS: Since the histopathological responses were as expected, DCF with prophylactic pegfilgrastim is considered to be effective as preoperative chemotherapy. However, the prophylactic use of pegfilgrastim on day 7 was insufficient to prevent FN.

Language：English Publishing type：Research paper (scientific journal)

Late-onset postoperative pneumonia (LOPP) after esophagectomy is poorly understood. This study was designed to clarify the features and risk factors for this event. Patients who underwent esophagectomy for esophageal cancer between 2006 and 2016 were included. LOPP was defined as radiologically proven pneumonia that occurred over 3 months after surgery, and clinically relevant late-onset postoperative pneumonia (CR-LOPP) was defined as LOPP that required administration of oxygen and antibiotics in the hospital and/or more intensive treatment. The total psoas muscle area (TPA) was measured using preoperative and postoperative (at 3 months after surgery) computed tomography scan images. Potential risk factors for CR-LOPP were investigated. Among 175 study patients, 46 (26.3%) had LOPP, 29 (16.6%) of whom exhibited CR-LOPP with a cumulative incidence of 15.6% at 3 years and 22.4% at 5 years. Four (13.8%) of these patients died of LOPP. Univariable analysis showed that clinical stage ≥III (P = 0.005), preoperative prognostic nutritional index (PNI) <45 (P = 0.035), arrhythmia (P = 0.014), postoperative hospital stay ≥40 days (P = 0.003), and percent decrease of TPA more than 5% (P < 0.001) were associated with CR-LOPP but not early onset postoperative pneumonia. Multivariable analysis revealed that clinical stage ≥III (hazard ratio [HR] 3.01, P = 0.004), postoperative hospital stay ≥40 days (HR 2.51, P = 0.015), and percent decrease of TPA >5% (HR 9.93, P < 0.001) were independent risk factors for CR-LOPP. CR-LOPP occurred in over 20% of patients at 5 years, and early postoperative loss of TPA was a potential trigger for this delayed complication.

Trefoil factor 1 inhibits the development of esophageal adenocarcinoma from Barrett's epithelium. International journal

Keiji Hasebe, Kimitoshi Yamazaki, Junpei Yamaguchi, Toshio Kokuryo, Yukihiro Yokoyama, Kazushi Miyata, Masahide Fukaya, Masato Nagino, Tomoki Ebata

Laboratory investigation; a journal of technical methods and pathology Vol. 102 ( 8 ) page： 885 - 895 2022.8

Language：English Publishing type：Research paper (scientific journal)

Trefoil factor family 1 (TFF1) is one of three members of the trefoil factor family that are abundantly expressed in the gastrointestinal mucosal epithelium. Recent studies have shown that TFF1 acts as a tumor suppressor in gastric, pancreatic and hepatocellular carcinogenesis; however, little is known about its function in esophageal carcinogenesis, especially in esophageal adenocarcinoma (EAC). Barrett's epithelium is the metaplastic columnar epithelium of the esophagus and a known premalignant lesion of EAC. To investigate the role of TFF1 in EAC development, a mouse model of Barrett's epithelium was employed, and human specimens of EAC were assessed by immunohistochemistry (IHC) and methylation-specific PCR. Wild-type (WT) mice underwent gastrojejunostomy on the forestomach, resulting in the development of Barrett's epithelium-like (BE-like) epithelium adjacent to the anastomotic site. BE-like epithelium in these mice expressed TFF1, indicating the association of TFF1 with esophageal adenocarcinoma. TFF1-knockout (TFF1KO) mice underwent the same procedure as well, revealing that a deficiency in TFF1 resulted in the development of adenocarcinoma in the anastomotic site, presumably from BE-like epithelium. IHC of human samples revealed strong TFF1 expression in Barrett's epithelium, which was lost in some EACs, confirming the association between TFF1 and EAC development. Aberrant DNA hypermethylation in TFF1 promoter lesions was detected in TFF1-negative human EAC samples, further confirming not only the role of TFF1 in EAC but also the underlying mechanisms of TFF1 regulation. In addition, IHC revealed the nuclear translocation of β-catenin in human and mouse EAC, suggesting that activation of the Wnt/β-catenin pathway was induced by the loss of TFF1. In conclusion, these results indicate that TFF1 functions as a tumor suppressor to inhibit the development of esophageal carcinogenesis from Barrett's epithelium.

<p>We report two cases of cholangiocarcinoma with a small cell carcinoma (SCC) component that exhibited contrasting courses after resection, with early death versus long-term survival. Case 1 was a 70-year-old man who underwent left hepatectomy with caudate lobectomy for perihilar cholangiocarcinoma. Histopathological examination showed adeno-neuroendocrine carcinoma composed of papillary adenocarcinoma and SCC. The tumor was classified as pT2N0M0, Stage II, but with extensive venous invasion from SCC. Gemcitabine alone was administered postoperatively based on normal treatment of biliary tract cancer, but the patient died only five months after surgery due to early relapse with multiple liver metastases. Case 2 was a 65-year-old man who underwent subtotal stomach preserving pancreatoduodenectomy for distal cholangiocarcinoma. Histopathological examination showed neuroendocrine SCC with lymph node metastasis. The tumor was classified as pT2N1M0, Stage III. As standard chemotherapy for pulmonary SCC, cisplatin plus etoposide was given for 4 cycles postoperatively. The patient has been alive without recurrence for 8 years after surgery. An SCC component in cholangiocarcinoma often leads to early relapse with subsequent cancer-related death after resection. Therefore, multidisciplinary approach including chemotherapy similar to that for pulmonary SCC should be considered in this setting.</p>

BACKGROUND & AIMS: To elucidate the impact of synbiotics on bacterial translocation and subsequent bacteremia during neoadjuvant chemotherapy for esophageal cancer. METHODS: Patients requiring neoadjuvant chemotherapy for esophageal cancer were randomized to receive synbiotics (synbiotics group) or no synbiotics (control group) during chemotherapy. Blood and fecal samples were taken before and after every chemotherapy cycle, and 1 day before surgery. Mesenteric lymph nodes (MLNs) were harvested at laparotomy (MLN-1) and after resection of the tumor (MLN-2). Bacteria in each sample were detected. Fecal microbiota and organic acid concentrations were also determined. The primary endpoint was the detection of bacteria in the blood samples, as well as the incidence of side effects during chemotherapy. The secondary endpoint was the detection rate of bacteria in the MLN samples collected during surgery. RESULTS: The study recruited a total of 42 patients (22 in the control group, 20 in the synbiotics group). Bacteria were detected in 16 of 101 blood samples in the control group, whereas those were detected only 2 of 100 blood samples in the synbiotics group (p < 0.001) during neoadjuvant chemotherapy. Additionally, bacteria were detected in 12 of 34 MLN samples in the control group, whereas no bacteria were detected in 38 MLN samples in the synbiotics group (p < 0.001). Suppression of bacterial translocation was at least partly associated with an increased fecal acetic acid concentration as well as a lowered fecal pH by synbiotics. The incidence rate of grade 3 gastrointestinal toxicity during chemotherapy was lower in the synbiotics group compared to the control group (8/22 vs. 1/20, p = 0.022). CONCLUSIONS: Neoadjuvant chemotherapy for esophageal cancer may induce bacterial translocation and subsequent bacteremia, which can be prevented by synbiotics administration.

In Japan, esophagectomy after two courses of 5-fluorouracil plus cisplatin is regarded a standard strategy for treating resectable stage II or III esophageal squamous cell carcinoma (ESCC). However, 5-fluorouracil plus cisplatin does not benefit cohorts with clinical stage III ESCC, suggesting the requirement for a more effective regimen. We are conducting a single-arm phase II study to assess the safety and efficacy of neoadjuvant docetaxel, oxaliplatin plus S-1 (DOS) for treating patients with clinical stage III ESCC. The primary endpoint is the pathological response rate, and the target number is 45 patients. Safety, response rate, R0 resection rate, and survival are secondary endpoints. This trial is registered in the Japan Registry of Clinical Trials as jRCTs041210023. We are conducting a prospective phase II trial to evaluate the safety and efficacy of three courses of neoadjuvant DOS treatment followed by radical esophagectomy for clinical stage III ESCC.
