RESUMEN
A 28-year-old female patient with no particular medical history had a sore throat seven days before admission. Subsequently, she developed malaise, right abdominal pain, and a fever of 38°C and visited our hospital. A blood test revealed a mild inflammatory response and elevated liver enzymes, and she was admitted to the hospital for detailed examination and acute liver injury treatment. Various viral tests and autoantibody measurements revealed elevated Epstein-Barr virus (EBV) immunoglobulin M and negative EB nuclear antigen antibodies. Therefore, she was diagnosed with primary infectious mononucleosis-associated EB viral hepatitis. Abdominal computed tomography upon admission revealed swollen lymph nodes around the stomach;thus, esophagogastroduodenoscopy (EGD) was performed. A histopathological examination revealed severe lymphocytic infiltration, and EB encoding region in situ hybridization demonstrated that 10-20% of the lymphocytes were EBV-infected. Drip and rest treatment improved the patient's liver enzymes, and her symptoms resolved. Repeat EGD after two months revealed improved gastric erosions. Here, we report a case of EBV-associated gastritis that was discovered due to perigastric lymphadenopathy accompanied by infectious mononucleosis. This report includes a review of the literature because a few studies reported EBV-associated gastritis.

INTRODUCTION: We investigated the hemostatic effect and safety of a hemostatic peptide solution for the treatment of gastrointestinal bleeding requiring emergency endoscopy. METHODS: We retrospectively examined the patient backgrounds, hemostatic results, and procedural safety in patients who were treated with a hemostatic peptide solution for hemostasis during emergency endoscopies for gastrointestinal bleeding. All hemostatic procedures were performed by nonexpert physicians with less than 10 years of endoscopic experience. All of the cases were treated at a single institution over the months from January 2022 to January 2023. RESULTS: Twenty-six consecutive patients (17 males and 9 females) with a median age of 74 (45-95) years were included. Their conditions requiring emergency endoscopy were melena in 8 patients, hematochezia in 2, hematemesis in 8, anemia in 6, and bleeding during esophagogastroduodenoscopy in 2. The sites of bleeding were the esophagus in 3 patients, the stomach in 17, the duodenum in 3, the small intestine in 2, and the colon in 1. Hemostasis was obtained with another hemostasis device used in conjunction with the hemostatic peptide solution in 13 cases and with the hemostatic peptide solution alone in 13 cases. The hemostasis success rate was 100%, with no complications. Rebleeding occurred within 1 week in 4 cases. CONCLUSION: Hemostasis with the hemostatic peptide solution was safe and provided a temporary high hemostatic effect in emergency gastrointestinal endoscopy.

Trousseau syndrome is a paraneoplastic syndrome associated with a risk of poor prognosis. We reviewed the survival time and prognosis of patients with Trousseau syndrome. We identified 40 cases from 28 reports of Trousseau syndrome due to pancreatic cancer. We analyzed 20 cases based on reports providing sufficient information on the stage/location of pancreatic cancer and survival time after Trousseau syndrome. The median survival time was 2.0 months. There was no statistical difference between performance status (PS) 0-1 and PS 4, stages I-III and IV, and pancreatic head and body/tail. However, statistically significant differences were noted between the median survival time of patients who continued treatment for pancreatic cancer even after Trousseau syndrome and those who discontinued treatment (P = 0.005). Although only a small number of cases were analyzed in this study, the results indicated that patients with pancreatic cancer who developed Trousseau syndrome had a poor prognosis, and chemotherapy should be continued, if possible.

Intrahepatic cholangiocarcinoma is a condition with a poor prognosis. Traditionally, there was no cure unless important drugs such as gemcitabine, cisplatin, and tegafur/gimeracil/uracil potassium showed efficacy. Pemigatinib has recently become accessible for the treatment of intrahepatic cholangiocarcinoma with FGFR2 fusion or rearrangement gene abnormalities. Hyperphosphatemia is typically linked to pemigatinib. In the current case, pemigatinib was used to effectively treat a 48-year-old woman, and hypophosphatemia was observed. Patients with intrahepatic cholangiocarcinoma should undergo aggressive cancer multigene panel testing as well as careful monitoring of serum phosphorus levels.
RESUMEN
A 61-year-old patient with advanced gastric cancer was treated with ramucirumab plus albumin-suspended paclitaxel as second-line treatment. The treatment resulted in exposure of the right mandible around an implant. The implant was removed, and sequestration was not observed. The patient was diagnosed with oral mucosal necrosis. Thus, implants may cause mucosal necrosis due to angiogenesis inhibitors.

Since colorectal metastases from primary lung cancer are rare, the location of metastatic lesion and prognostic factors have not been well evaluated. Therefore, we carried out a systematic review and meta-analysis to assess the clinicopathological characteristics and prognostic factors of Japanese patients with colorectal metastasis from lung cancer. We searched the Ichushi-Web database from January 1964 to December 2020. We found 59 colorectal metastases in 52 cases for this meta-analysis. Small cell carcinoma was shown to have significantly more metastases to the appendix than non-small cell carcinoma. However, there was no significant correlation between location and histology when classified into right and left colons (P = 0.247). The median overall survival after diagnosis was 6 months. Univariate analysis showed that adenocarcinoma (Hazard Ratio (HR) 0.383, P = 0.024), simultaneous metastasis (HR 0.325, P = 0.046), and chemotherapy group (HR 0.482, P = 0.044) were good prognostic factors. Multivariate analysis confirmed that chemotherapy (HR 0.38, P = 0.02) was an independent good prognostic factor for overall survival. In conclusion, although there was no statistical difference, right colon metastases were more frequent than left colon metastases. Chemotherapy may be effective for colorectal metastases from lung cancer.
RESUMEN
Esophageal neuroendocrine cell carcinoma (NEC) is extremely rare, and its treatment strategy has not been established. Systematic review and meta-analysis were carried out to assess the treatment and prognosis of patients with esophageal NEC in Japan. The Ichushi-Web database was searched from January 1964 to May 2018. In total, 141 cases of esophageal NEC were included in the analysis. The survival of the chemotherapy group with stage II/III esophageal NEC was better than that of the surgery group. Meanwhile, the survival of the adjuvant treatment group with stage II/III esophageal NEC was significantly better than that of the surgery alone group. In patients with stage IV esophageal NEC, no significant differences were observed in terms of treatment response from the three regimens: irinotecan/platinum and etoposide/platinum compared with 5-fluorouracil/platinum. Moreover, no significant differences were observed in the survival of patients who received the chemotherapy regimens. However, the 2-year survival rates of the irinotecan/platinum (26%) group and etoposide/platinum (27%) group were higher than that of the 5-fluorouracil/platinum (0%) group. In esophageal NEC, chemotherapy may be used as the first-line treatment. Irinotecan/platinum or etoposide/platinum can be the first-line regimen for chemotherapy. However, the additive effects of surgery remain unclear.
RESUMEN
BACKGROUND: The mean 5-6-month survival after failed standard chemotherapy for metastatic colorectal cancer (mCRC) necessitates more effective treatments for refractory mCRC. For untreated mCRC, S-1 + oral leucovorin (SL) therapy offers promising results without severe toxicity. The ML18147 trial demonstrated that bevacizumab (Bev) prolongs overall survival after mCRC progression. We conducted a single-centre phase-II trial to evaluate the safety and efficacy of SL/Bev combination chemotherapy as mCRC salvage therapy. METHODS: Major eligibility criteria were confirmed adenocarcinoma diagnosis; age >20 years; Eastern Cooperative Oncology Group performance status, 0-2; and progression after administration/intolerance of/to approved drugs for mCRC. (5-FU, oxaliplatin, irinotecan, Bev, and anti-EGFR antibody, if KRAS wild-type). S-1 (80-120 mg/body) and leucovorin (25 mg) were orally administered in a 1-week-on/1-week-off schedule. Bev (5 mg/kg) was administered on day 1 of every 2-week cycle. The primary endpoint was disease control rate (DCR). RESULTS: A total of 31 patients were enrolled. DCR was 65% [95% confidence interval (CI), 48-100%] and the response rate was 7% (95% CI, 0.7-22%). One patient showing partial response to SL/Bev had a BRAF-mutant tumor. Median progression-free survival and overall survivals were 5.3 [95% CI, 2.1-9.3] and 9.9 [95% CI, 7.4-NA] months, respectively. The most-frequent grade-3/4 adverse events were mucositis (26%) and diarrhea (11%), which were manageable by dose reduction/interruption. CONCLUSIONS: SL/Bev showed impressive activity in refractory mCRC and was tolerable, suggesting its potential as an alternative chemotherapy for refractory mCRC. TRIAL REGISTRATION: This study has been registered in University Hospital Medical Information Network (UMIN) Clinical Trials Registry ( ID UMIN000009083 ) on 11 October 2012.

The relative risk of cancer recurrence with postoperative adjuvant FOLFOX/CapeOX therapy(Ox)for stage III colorectal cancer is reduced by approximately 20%when compared to that with fluorouracil plus Leucovorin. We performed a questionnaire survey to evaluate the quality of life(QOL)and extent of side effects in patients who received adjuvant chemotherapy. In order to evaluate the risks and benefits of oxaliplatin administration, we also examined the differences in awareness of oxaliplatin side effects between patients and medical staff. Responses were obtained from 147 patients, 54 doctors, and 84 nurses. Analysis of the patient responses showed higher current QOL scores regardless of the chemotherapy regimen, although patients in the Ox group had a high rate of residual sensory peripheral neuropathy. In the Ox group, 81% of patients responded that the side effects were moderate. In contrast, 40% of medical staff identified the side effects of oxaliplatin as severe, which differed from that reported by the patients. Considering that Ox adjuvant chemotherapy may reduce the risk of recurrence by approximately 20%, the risk/benefit balance is acceptable.

PURPOSE: The prognostic and predictive values of carbohydrate antigen 19-9 (CA19-9) levels in metastatic colorectal cancer (mCRC) remain unclear. We reviewed all mCRC patients at a single institution to evaluate the relationship between CA19-9 levels and survival. METHODS: Two hundred and fifty-two patients underwent first-line chemotherapy using oxaliplatin-based regimens between April 2005 and December 2009. The relationship between baseline CA19-9 levels and survival was analyzed. Moreover, we evaluated the relationship between baseline CA19-9 levels and clinicopathological factors. RESULTS: One hundred and fifty patients had elevated baseline CA19-9 levels (elevated group), and 79 patients had normal baseline CA19-9 (normal group) levels. Both KRAS and BRAF mutation rates were higher in the elevated group than in the normal group. Elevated CA19-9 level was a poor prognostic factor compared with normal CA19-9 levels (P = 0.0021). In the elevated group, the median survival time with bevacizumab was significantly longer with bevacizumab than without it (median OS, 27.8 vs. 15.3 months, P = 0.0019). However, the median survival time was not different with or without bevacizumab in the normal group (median OS, 36.5 vs. 38.0 months, P = 0.9515). CONCLUSION: Our results suggest that baseline CA19-9 level is an independent prognostic factor in mCRC patients, and it correlated with the KRAS/BRAF mutation status. Bevacizumab exhibits clinical activity only for high CA19-9 levels in mCRC.

BACKGROUND: The long-term outcomes of advanced gastric cancer (AGC) patients treated with S-1 plus cisplatin (SP) combination chemotherapy remain unclear. Therefore, we sought to evaluate these outcomes to identify the prognostic factors affecting patient survival. METHODS: We retrospectively analyzed 153 AGC patients treated with SP at a single institution between January 2005 and July 2011. RESULTS: Median overall survival (OS) was 15.0 months [95 % confidence interval (CI), 12.5-17.9 months]. Three independent prognostic factors affecting poor survival were identified: performance status (PS) ≥ 1 [hazard ratio (HR) = 2.39, 95 % CI, 1.58-3.62); >1 metastatic site (HR = 1.57, 95 % CI, 1.10-2.26], and elevated alkaline phosphatase levels (HR = 1.70, 95 % CI, 1.16-2.49). A simple prognostic index was generated using three risk groups: good (no risk factor), moderate (one or two risk factors), and poor (three risk factors). The median OS for good-, moderate-, and poor-risk groups was 28.6, 14.8, and 7.3 months, respectively (log-rank test; P < 0.0001). Among the twelve 3-year survivors, 9 (75 %) had a PS of 0 and 8 (67 %) had only one metastatic site. CONCLUSIONS: Three prognostic factors were identified in AGC patients treated with SP. Using a simple prognostic index, the patients were divided into three risk groups, in which the survival differences were markedly significant, suggesting that patients with good PS and only one metastatic site may have a higher chance of long-term survival than those with poor PS and multiple metastatic sites.

The use of transgenic avian allows cost effective and safe production of pharmaceutical proteins. Here, we report the successful production of chimeric chickens expressing human erythropoietin (hEpo) using a high-titer retroviral vector. The hEpo expressed by transgenic hens accumulated abundantly in egg white and had N- and O-linked carbohydrates. While attachment of terminal sialic acid and galactose was incomplete, portions of N- and O-linked carbohydrates were present. In vitro biological activity of egg white-hEpo was comparable to that produced by recombinant CHO cells.
