RESUMEN
Background: The commercial availability of anamorelin, Japan's first therapeutic agent for cancer cachexia in 2021, led to an investigation into its prescription patterns at Toyama University Hospital. Objective: We aimed to analyze anamorelin prescription trends and outcomes among cancer cachexia patients. Methods: A retrospective study from July 2021 to December 2022 examined 88 cases, assessing demographics, cancer types, prescription locations, and meal intake changes. Results: Anamorelin usage was predominant during chemotherapy, especially for pancreatic cancer in outpatient settings. Approximately 30% experienced increased meal intake. Chemotherapy-initiated cases had a longer median duration (55 days) compared with best supportive care only cases (12 days). Conclusion: Anamorelin demonstrated significant prescription patterns, particularly during chemotherapy for pancreatic cancer in outpatient settings, suggesting potential efficacy enhancements when administered with chemotherapy in cancer cachexia management. The study underscores the importance of tailored approaches to optimize anamorelin's therapeutic benefits.

Currently, no established marker exists for predicting peritoneal metastasis progression during chemotherapy, although they are major interruptive factors in sequential chemotherapy in patients with advanced gastric cancer (AGC). This multicenter retrospective study was conducted from June 2015 to July 2019, analyzing 73 patients with AGC who underwent taxane-plus-ramucirumab (TAX/RAM) therapy and had their serum carbohydrate antigen 125 (CA125) concentrations measured. Of 31 patients with elevated CA125 levels above a cutoff of 35 U/mL, 25 (80.6%) had peritoneal metastasis. The CA125 concentrations before TAX/RAM treatment were associated with ascites burden. The overall survival was significantly shorter in the CA125-elevated group. CA125 kinetics, measured at a median of 28 days after chemotherapy, were associated with the ascites response (complete or partial response: -1.86%/day; stable disease: 0.28%/day; progressive disease: 2.33%/day). Progression-free survival in the CA125-increased group, defined by an increase of 0.0067%/day using receiver operating characteristic curve analysis, was significantly poorer among patients with peritoneal metastases. In conclusion, this study highlights that CA125 kinetics can serve as an early predictor for the progression of peritoneal metastasis during TAX/RAM treatment.
RESUMEN
(1) Background: Nivolumab plus chemotherapy is established as a first-line treatment for advanced gastric cancer (AGC). While mFOLFOX6 is commonly used for AGC with severe peritoneal metastasis, the efficacy of nivolumab combined with it remains uncertain. We evaluated the outcomes of nivolumab plus mFOLFOX6 for AGC with severe peritoneal metastasis in clinical practice. (2) Methods: This multicenter retrospective study was conducted between December 2021 and June 2023. We investigated AGC patients with massive ascites or inadequate oral intake due to severe peritoneal metastasis and who received nivolumab plus mFOLFOX6. (3) Results: Among 106 patients treated with nivolumab plus chemotherapy, 21 (19.8%) had severe peritoneal metastasis, with 14 receiving nivolumab plus mFOLFOX6. The median progression-free survival was 7.4 months (95%CI 1.9-10.1), and the median overall survival was 10.7 months (95%CI 5.3-NA), with four patients (28.5%) surviving more than 12 months. Improved ascites and oral intake were observed in 6/14 patients (42.8%) and 10/11 patients (90.9%), respectively. The major grade 3 or more adverse events included leukopenia (28.5%) and neutropenia (21.4%), with no severe immune-related adverse events reported. (4) Conclusions: The safety and moderate efficacy of nivolumab plus mFOLFOX6 were suggested even in AGC patients with severe peritoneal metastasis.
RESUMEN
Multifocal fatty liver nodules can present a diagnostic challenge due to their resemblance to metastatic liver disease. This case report illustrates the complexity of such scenarios through the presentation of a middle-aged male patient. Despite the common nature of fatty liver disease, characterized by hepatocyte fat accumulation leading to diffuse and uniform liver lesions, rare instances exhibit heterogeneous appearances. The case underlines the potential confusion arising from imaging modalities when multiple small nodules disperse throughout the liver, mimicking multifocal tumors or metastases. The report emphasizes the critical role of comprehensive diagnostic procedures in preventing misdiagnosis and unwarranted interventions. Effective management hinges on multidisciplinary collaboration among specialists, ensuring accurate differentiation and appropriate treatment. This study serves as a reminder of the intricacies involved in interpreting multifocal fatty liver nodules that may masquerade as metastatic disease, highlighting the need for precision in clinical practice.
RESUMEN
BACKGROUND: Staying at home during the dying process is important for many patients; and palliative care units (PCUs) can help facilitate home death. This study compared patient survival between those who were discharged to home from a palliative care unit and those who were not, and aimed to identify the factors associated with home death after the discharge. METHODS: This retrospective cohort study used a database of patients admitted to a palliative care unit at Kouseiren Takaoka Hospital in Japan. All consecutive patients admitted to the hospital's PCU between October 2016 and March 2020 were enrolled. Patient survival and factors potentially associated with survival and place of death were obtained. A total of 443 patients with cancer were analyzed, and 167 patients were discharged to home and 276 were not. RESULTS: Propensity score matching analyses revealed that median survival time was significantly longer in patients who were discharged to home than those who were not (57 vs. 27 days, P < 0.001). Multiple logistic regression analysis identified that worse Palliative Prognostic Index (odds ratio [OR] = 1.21, 95% confidence interval [CI] = 1.03-1.44, p = 0.025) and family members' desire for home death (OR = 6.30, 95% CI = 2.32-17.1, p < 0.001) were significantly associated with home death after their discharge. CONCLUSIONS: Discharge to home from palliative care units might have some positive impacts on patient survival.

Introduction: The efficacy of immune checkpoint inhibitors (ICIs) is heterogeneous at each metastatic site, and tumor progression pattern is associated with survival; however, it remains unclear in gastric cancer (GC). Therefore, we aimed to clarify the progression pattern in response to ICIs in patients with GC, and we analyzed its mechanism focusing on the intratumoral immune cells. Methods: Patients who received ICIs were retrospectively classified into non-systemic and systemic progression groups based on their radiological assessments. Moreover, the best percentage change in target lesions from each organ was compared. Results: Among 148 patients, the non-systemic progression group showed a significant improvement in overall survival (OS) compared with the systemic progression group (median, 5.6 months vs. 3.3 months; HR, 0.53; 95%CI, 0.32-0.89; p = 0.012). Poor performance status (HR, 1.73, 95%CI, 1.00-2.87) and systemic progression (HR, 3.09, 95%CI, 1.95-4.82) were associated with OS. Of all metastatic sites, the liver showed the poorest percentage change, and liver metastasis (OR, 2.99, 95%CI, 1.04-8.58) was associated with systemic progression. Hence, intratumoral CD8+ T-cell density was lower in patients with liver metastasis than in those without liver metastasis after ICIs, although the density of CD4+ T-cells (Th1, Th17, and Treg) and CD163+ cells (TAM) were not significantly different. Conclusion: The new progression pattern was associated with OS in GC. Liver metastasis may be a predictive factor of systemic progression during ICIs by regulating intratumoral CD8+ T-cells.
RESUMEN
OBJECTIVE: JCOG1106, a randomized phase II trial conducted to compare chemoradiotherapy (S-1 concurrent radiotherapy) with (Arm B) or without (Arm A) induction chemotherapy using gemcitabine in patients with locally advanced pancreatic cancer, showed a more favorable long-term survival in Arm A. This study was aimed at exploring whether some subgroups classified by the systemic inflammatory response might derive greater benefit from either treatment. METHODS: All subjects eligible for JCOG1106 were included in this analysis (n = 51/49 in Arm A/B). This exploratory subgroup analysis was performed by Cox regression analysis to investigate the impact of the systemic inflammatory response, as assessed based on the serum C-reactive protein, serum albumin (albumin), Glasgow Prognostic Score and derived neutrophil-lymphocyte ratio, at the baseline on overall survival. P values <0.1 for the interaction were regarded as denoting significant association. RESULTS: Glasgow prognostic score showed significant treatment interactions for overall survival. Hazard ratios of Arm B to Arm A were 1.35 (95% confidence interval, 0.82-2.23) in the Glasgow Prognostic Score 0 (C-reactive protein ≤10 mg/L and albumin ≥35 g/L) (n = 44/34 in Arm A/B) and 0.59 (95% confidence interval, 0.24-1.50) in the Glasgow Prognostic Score 1/2 (C-reactive protein >10 mg/L and/or albumin <35 g/L) (n = 7/15) (P-interaction = 0.06). C-reactive protein alone and albumin alone also showed significant treatment interactions for overall survival. CONCLUSIONS: Survival benefits of induction chemotherapy in chemoradiotherapy for locally advanced pancreatic cancer were observed in patients with elevated Glasgow Prognostic Score, high C-reactive protein and low albumin. These results suggest that systemic inflammatory response might be considered to apply induction chemotherapy preceding chemoradiotherapy.

BACKGROUND: Staying at a preferred place, principally at home, is of great value for dying patients, and palliative care units (PCUs) have an important role in providing adequate support so that patients can be discharged and go home. We attempted to create and validate a scoring tool to predict whether a cancer patient admitted to a PCU will be discharged home. METHODS: All 369 cancer patients admitted to the PCU of a 533-bed general hospital in Japan from October 2016 to October 2019 were enrolled. As outcomes, we recorded whether patients were discharged to home, died in hospitals, or were discharged to other hospitals. Attending physicians recorded 22 potential scale items at admission, including (I) demographic variables, (II) patient general conditions, (III) vital signs, (IV) medications, and (V) patient symptoms. Training-testing procedure to develop a screening score was performed. RESULTS: Among 369 cancer patients admitted to the PCU, we excluded 10 cases for whom a death location could not be identified. Among the remaining 359 patients, 180 were analyzed in the development phase and 179 in the validation phase. Multivariate logistic regression analysis identified five items as independent factors associated with discharge to home, and a prediction equation was created using the regression coefficients: sex (female, 4 points), calorie intake (520 kcal or more, 19 points), availability of daytime caregivers (11 points), family's preferred place of care (home, 139 points), and symptoms that resulted in hospitalization (not fatigue, 7 points). Using a cutoff point of 155, the area under the curve (AUC) value was 0.949 with 95% confidence intervals of 0.918 to 0.981. In the validation sample, the sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), and error rate were 75.3%, 86.3%, 82.2%, 80.6%, and 18.4%, respectively. CONCLUSIONS: Whether a patient admitted to a PCU can discharge to home could be predicted using the simple clinical tool. Further validation and outcome studies are warranted.

INTRODUCTION: Third-line chemotherapy has been suggested to improve survival in patients with gastric cancer. This study aimed to identify factors associated with the induction of third-line chemotherapy for advanced gastric cancer, focusing on patient eligibility for clinical trial. METHODS: We retrospectively analyzed 335 patients treated for unresectable or recurrent gastric cancer between April 2009 and May 2020. The patients were grouped into those that met the key eligibility criteria for clinical trial (136 patients, 40.6%) and those that did not (199 patients, 59.4%) before receiving first-line chemotherapy. RESULTS: The overall survival (OS) was 16.8 months (95% CI: 14.0-19.6) and 9.3 months (95% CI: 7.8-11.0) in the eligible and ineligible group, respectively. Multivariate analyses to identify the risk factors associated with the induction of third-line chemotherapy revealed ineligibility of clinical trial (OR 1.95; 95% CI: 1.15-3.31), number of metastatic sites (OR 1.99; 95% CI: 1.23-3.22), low albumin concentration (OR 2.24; 95% CI: 1.14-4.38), and a lack of complete or partial response to first-line treatment (OR 1.85; 95% CI: 1.05-3.26). Indeed, in responders to first-line treatment for ineligible patients, the median OS was 17.7 months (95% CI: 10.6-27.9), respectively. CONCLUSIONS: Treatment outcomes were different for those eligible for clinical trials and those who were not. However, this study suggested that patients who responded to first-line treatment have more favorable prognosis when treated with salvage chemotherapy, even if they were deemed ineligible for clinical trials.

BACKGROUND: Although initial therapy with a parenteral anticoagulant is required before edoxaban, this strategy is frequently avoided in actual clinical practice because of its complexity. This study assessed the feasibility of edoxaban without initial heparin usage for asymptomatic cancer-associated thrombosis (CAT) in Japanese patients with gastrointestinal cancer (GIC) at high risk of bleeding. METHODS: In this multicenter prospective feasibility study conducted at 10 Japanese institutions, patients with active GIC who developed accidental asymptomatic CAT during chemotherapy were recruited. Edoxaban was orally administered once daily without initial parenteral anticoagulant therapy within 3 days after detecting asymptomatic CAT. The primary outcome was the incidence of major bleeding (MB) or clinically relevant non-major bleeding (CRNMB) during the first 3 months of edoxaban administration. RESULTS: Of the 54 patients enrolled from October 2017 to September 2020, one was excluded because of a misdiagnosis of CAT. In the remaining 53 patients, the primary outcome occurred in six patients (11.3%). MB occurred in four patients (7.5%), including gastrointestinal bleeding in three patients and intracranial hemorrhage in one patient. CRNMB occurred in two patients (3.8%), including bleeding from the stoma site and genital bleeding in one patient each. There were no deaths attributable to bleeding, and all patients who experienced MB or CRNMB recovered. CONCLUSIONS: The risk of bleeding after edoxaban without heparin pretreatment was acceptable, demonstrating new treatment options for asymptomatic CAT in patients with GIC.

BACKGROUND/AIM: Advanced gastric cancer (AGC) rarely presents with disseminated intravascular coagulation (DIC) at the time of diagnosis. Chemotherapy should be selected in consideration of hematological toxicities because these patients are at high risk of hemorrhagic complications. The leucovorin, fluorouracil, and oxaliplatin (FOLFOX) regimen is an effective and less toxic regimen for patients with AGC and poor performance status. PATIENTS AND METHODS: The present study assessed overall survival of all patients receiving first-line chemotherapy with and without DIC using Kaplan-Meier methods and examined the clinicopathological factors, DIC parameters, response, and survival of five patients with AGC and DIC who received FOLFOX in the first-line setting between February 2017 and February 2020. RESULTS: Among the patients, four patients (80%) recovered from DIC after a median of 12 days of FOLFOX therapy (range=12-25), and their platelet count gradually increased within 1 week after the start of chemotherapy. The median progression-free survival and overall survival were 46 (range=22-296) and 115 days (range=83-324), respectively. No patients experienced adverse events necessitating treatment discontinuation, including gastrointestinal bleeding and thrombocytopenia. Moreover, all patients received second-line treatment after progression, and one patient exhibited improvement of DIC symptoms following nab-paclitaxel and ramucirumab treatment. CONCLUSION: FOLFOX therapy is well tolerated and effective in patients with AGC initially presenting with DIC and subsequent second-line treatment might be crucial for better prognosis.

Background: It is unclear which laxatives are appropriate to prevent opioid-induced constipation (OIC). This study will evaluate whether prophylactic use of naldemedine prevents OIC in patients with cancer who start opioid administration. Methods: This study is a multicenter, double-blinded, randomized, placebo-controlled trial. Patients who meet the eligibility criteria and give consent will be randomly assigned to the naldemedine or placebo group. Both groups will take each drug once a day after breakfast for 14 days. Results: The primary endpoint is the proportion of patients with a Bowel Function Index of less than 28.8 on Day 14. The secondary endpoints include assessment scales of the impact of constipation on comprehensive quality of life. Conclusions: This is the first study proposed to assess the superiority of naldemedine over placebo in the prevention of OIC. If naldemedine is found to be effective in reducing OIC compared with the placebo, it will be regarded as a new standard for OIC prophylaxis at opioid initiation.

RESUMEN
INTRODUCTION: Combination chemotherapy with oxaliplatin, irinotecan, fluorouracil and leucovorin (FOLFIRINOX) has become one of the standard treatments for metastatic pancreatic cancer. However, the use of FOLFIRINOX requires prolonged infusion. Therefore, we planned to develop a new combination chemotherapy regimen with oxaliplatin, irinotecan and S-1 (OX-IRIS) for advanced pancreatic cancer. In the phase â study that was conducted previously, the safety and recommended dose of OX-IRIS were assessed. In this study, we will evaluate the efficacy and safety of OX-IRIS. METHODS AND ANALYSIS: The HGCSG1803 study started as a multicentre, non-randomised, single-arm, prospective, phase II study in December 2019. Eligible subjects were patients with untreated metastatic or relapsed pancreatic cancer. OX-IRIS is administered as follows: 30 min infusion of antiemetic; 2-hour infusion of oxaliplatin (65â¯mg/m2); 1.5-hour infusion of irinotecan (100â¯mg/m2) on day 1 and 15 of each 4-week cycle; and oral S-1 (40 mg/m2) twice daily from after dinner on day one to after breakfast on day 15, followed by a 14-day rest, to be repeated every 2 weeks until disease progression, unacceptable toxicity or patient refusal. The primary endpoint is response rate. The secondary endpoints are overall and progression-free survival, safety and dose for each drug. Using a binomial test, a sample size of 40 patients was set with a threshold value of 10% and expected value of 30%. Registration of 40 cases is planned from 18 institutions in Japan. ETHICS AND DISSEMINATION: All the procedures will be conducted in accordance with the ethical standards of the responsible committee on human experimentation (institutional and national) and with the Declaration of Helsinki of 1964 and its later versions. All the patients will receive written information about the trial and will provide informed consent before enrolment. This trial was approved by the Hokkaido University Certified Review Board (approval No: 018-037). TRIAL REGISTRATION NUMBER: jRCTs011190008.

We report two cases of patients with gastric linitis plastica (GLP), in which the histopathological diagnosis was made by endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) using a Franseen-tip needle. Esophagogastroduodenoscopy findings showed mucosal swelling and poor distensibility of the gastric antrum. Abdominal computed tomography findings showed significant thickening of the gastric wall at the antrum. Conventional endoscopic and bite-on-bite biopsy were attempted but resulted in failure to diagnose the lesions. We performed EUS-FNB to obtain histopathological samples from a deeper site, which confirmed the diagnosis. We considered this method safe and effective for the diagnosis of GLP.
RESUMEN
BACKGROUND: The purpose of this study was to clarify how the Regional Referral Clinical Pathway for Home-based Palliative Care (RRCP-HPC) and an outreach program by a palliative care team (PCT) lead to an improvement in the outcome. DESIGN AND METHODS: We conducted questionnaire surveys using the mailing method involving the regional medical staff involved in cancer patients introduced to the PCT of a single hospital, as well as bereaved families. The questionnaire was prepared through interviews with the medical staff and bereaved families. Subsequently, factor analysis was performed to identify factor structures and calculate the correlation coefficient with each outcome. RESULTS: For the questionnaire survey involving the medical staff, responses were collected from 119 regional medical institutions and 84 regional medical staff. The response rate per institution was 51.3%. Similarly, for the questionnaire survey involving bereaved families, the response rate was 42.4%. For the survey involving the medical staff, 6 factors, such as "improved awareness of an interdisciplinary team," were extracted. For the survey involving the bereaved families, 4 factors, such as "improvement of communications between patients and healthcare professionals," were extracted. There were significant (≥moderate) correlations between these factors and all outcomes. CONCLUSION: In this study, we clarified the process of achieving palliative care until death at home without difficulties using the outreach program and RRCP-HPC. The results suggest the importance of improving communications. The outreach program and RRCP-HPC may have contributed to palliative care at home without difficulties through an improvement in communications.

A de novo cardiac malignant tumor is rare and sometimes challenging to diagnose. We encountered a 67-year-old man without any medical history complaining of dyspnea on effort. On admission, his hemodynamics were deteriorated due to cardiac tamponade, which was improved by percutaneous drainage of 1,200 mL pericardial effusion, showing 11.0 g/dL of hemoglobin. We suspected primary cardiac malignancy following multidisciplinary tests, and a cardiac biopsy via sternotomy demonstrated the definitive diagnosis of primary malignant tumor (angiosarcoma) infiltrating the right atrial myocardium. We initiated weekly paclitaxel therapy. Further studies are warranted to establish the optimal diagnostic and therapeutic strategy for de novo cardiac malignancy.

We herein report a 73-year-old woman with BRAF V600E-mutated colon cancer treated with encorafenib plus cetuximab with binimetinib as standard salvage therapy for patients with advanced colorectal cancer. She developed bilateral serous retinal detachment the next day, and the regimen was discontinued, resulting in complete resolution by the third day. Doublet therapy without binimetinib was initiated along with a weekly ophthalmologic examination for 10 weeks without recurrence of retinal detachment. Thus, binimetinib was presumed to have been the cause of the retinal detachment. This clinical course suggests the need for close monitoring of patients for vision impairment and close collaboration with ophthalmologists.

Endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) enables easy and accurate pathological assessment. Here, we compared and assessed the area of samples on glass slides for three needle types: a 19-gauge Franseen needle (Acquire, Boston Scientific, Natick, MA, USA), a 22-gauge Franseen needle, and a 19-gauge fine-needle aspiration (FNA) needle (EZ Shot 3 Plus; Olympus, Tokyo, Japan). Among patients with suspected pancreatic cancer, with a ≥20 mm tumor located in the pancreatic body and tail, and who underwent EUS-FNA or FNB between June 2018 and March 2020, 10 were randomly selected to test each needle. The areas of histological tissue and blood clot samples were measured using the BZ-X800 imaging software (Keyence Corporation, Osaka, Japan). Baseline patient characteristics and pathological sample data showed no significant differences among the needles. The 19-gauge Franseen needle obtained significantly more histological tissue samples than the 19-gauge conventional needle (p = 0.010) and 22-gauge Franseen needle (p = 0.008). Conversely, there was no significant difference between the 19-gauge conventional needle and 22-gauge Franseen needle (p = 0.838) in this regard. The 19-gauge Franseen needle could collect more samples than the other needles, contributing to giving a more precise pathological diagnosis and more information, including genomic profiling.
RESUMEN
BACKGROUND: Constitutional mismatch repair deficiency (CMMRD) is an extremely rare autosomal recessive hereditary disease characterized by the absence of mismatch repair gene activity from birth, which results in brain tumors, colonic polyposis, gastrointestinal cancers, and lymphomas later in life. An aggressive approach, including colectomy or proctocolectomy, is recommended for the treatment of colorectal cancer. Additionally, partial colectomy with subsequent endoscopic surveillance may be an alternative strategy due to poor patient's condition, although there is no evidence of surveillance endoscopy after partial colectomy for CMMRD. CASE PRESENTATION: A 13-year-old male patient with a history of T-lymphoblastic lymphoma underwent total gastrointestinal endoscopy, which revealed rectal cancer, colorectal polyposis, and duodenal adenoma. Differential diagnosis included constitutional mismatch repair deficiency according to its scoring system and microsatellite instability, and subsequent germline mutation testing for mismatch repair genes confirmed the diagnosis of constitutional mismatch repair deficiency based on a homozygous mutation in mutS homolog 6 (MSH6). The patient and his family refused colectomy due to the high risk of malignancies other than colorectal cancer, which could require radical surgery. Therefore, the patient underwent low anterior resection of the rectosigmoid colon for rectal cancer and intensive surveillance endoscopy for the remaining colon polyposis. During the 3-year period after initial surgery, 130 polyps were removed and the number of polyps gradually decreased during 6-months interval surveillance endoscopies, although only one polyp was diagnosed as invasive adenocarcinoma (pT1). CONCLUSIONS: Our experience of short surveillance endoscopy illustrates that this strategy might be one of options according to patient's condition.

BACKGROUND: Immune-checkpoint inhibitors (ICI), including nivolumab and pembrolizumab, are among the standard treatments for previously treated advanced gastric cancer (AGC). This study aimed to evaluate the frequency of immune-related adverse events (irAEs) and the correlation between irAEs and their efficacy in AGC cases. PATIENTS AND METHODS: Patients were divided into two groups according to irAE occurrence. The frequency of irAEs and the treatment outcome (response rate [RR], progression-free survival [PFS], and overall survival [OS]) were evaluated. The survival rates were evaluated by landmark analysis considering lead-time bias. RESULTS: Among 108 patients who received nivolumab or pembrolizumab, 17 (15.7%) had irAEs. In a 4-week landmark analysis, the RR, median PFS, and median OS were 28.5%, 3.9 months (95% CI=2.8-9.3), and 12.2 months (95% CI=3.8-NA) in patients with irAEs, while 3.0% (2/65), 1.8 months (95% CI=1.4-2.1), and 3.5 months (95% CI, 2.9-5.1) in patients without irAEs, respectively. In multivariate analysis, irAEs were associated with better PFS (HR=2.08, 95% CI=1.34-3.21). CONCLUSION: The occurrence of irAEs was associated with a better clinical outcome of ICIs in patients with AGC.
