Serological response 5 months after the BNT162b2 COVID-19 vaccination in patients with various hematological disorders in Japan.

Purpose: Patients with hematological malignancies are at an increased risk of severe infection with coronavirus disease 2019 (COVID-19). However, developing an adequate immune response after vaccination is difficult, especially in patients with lymphoid neoplasms. Since the long-term effects of the BNT162b2 vaccine are unclear, the humoral immune response 5 months after the two vaccinations in patients with hematological disorders was analyzed.

Diagnosis of a -deficient undifferentiated tumor using multigene panel testing: A case report.

Key Clinical Message: -deficient thoracic carcinoma is a malignant tumor that may present as cancer of unknown primary. This tumor is refractory and requires a novel approach. In addition to identifying therapeutic targets, multigene panel testing can reveal novel genetic mutations, leading to more pathologically relevant diagnoses and appropriate tumor care.

Bidirectional information sharing between Nagoya Memorial Hospital and health insurance pharmacies using a communication sheet for pharmaceutical cooperation.

Background: We collaborated with the regional pharmaceutical associations near Nagoya Memorial Hospital and created a communication sheet for pharmaceutical cooperation between the hospital and health insurance pharmacies.

Methods: The communication sheet for pharmaceutical cooperation was issued in October 2014. We conducted a questionnaire survey of both cancer patients and community pharmacists 1 year after the implementation of the use of this sheet.

[A retrospective analysis of chemotherapy for gastric cancer in later-stage elderly patients].

Aim: Despite the significant advances in chemotherapy, the prognosis of unresectable or recurrent gastric cancer is still very poor. Given that older adults are likely to have a number of concomitant diseases and an impaired major organ function, cancer chemotherapy in elderly patients requires particular caution. We examined what factors are associated with the overall survival of gastric cancer patients undergoing chemotherapy.

Bladder squamous cell cancer accompanied by Trousseau's syndrome: a case report.

The association between thrombosis and cancer has been recognized since Trousseau's report in 1865. We present a case of bladder squamous cell carcinoma associated with multiple cerebral infarctions. This patient was diagnosed as having Trousseau's syndrome and received radiotherapy for bladder cancer treatment, along with anticoagulation therapy.

The efficacy and safety of docetaxel-based chemotherapy combined with dexamethasone 1 mg daily oral administration: JMTO Pca 10-01 phase II trial.

Objectives: Previously, one randomized control trial (TAX327) revealed the efficacy of docetaxel-based chemotherapy combined with prednisone. On the other hand, several studies showed a high prostate specific antigen (PSA) response with low-dose dexamethasone in castration-resistant prostate cancer (CRPC) patients. The objective of this study was to evaluate the efficacy and safety of docetaxel-based chemotherapy combined with dexamethasone in CRPC patients.

Chemo-Immunotherapy Using Lentinan for the Treatment of Gastric Cancer with Liver Metastases.

Gastric cancer is the third leading cause of cancer-related mortality worldwide. Systemic chemotherapy is the main treatment option for advanced gastric cancer when the tumor is inoperable. Despite recent advances in chemotherapeutic agents, the prognosis of unresectable or recurrent gastric cancer remains extremely poor.

[Cooperation between a Hospital without Dentists and Local Dental Associations in Oral Management of Cancer Patients].

Severe oral mucositis induced by cancer chemotherapy can cause intolerable pain and increase the risk of systemic infections, necessitating dose reduction and discontinuation of antineoplastic agents. Moreover, this adverse effect may have an impact on patient nutrition and quality of life. An effective and prophylactic intervention should be useful for alleviating this complication.

Importance of appropriate pharmaceutical management in pregnant women with ulcerative colitis.

Background: Ulcerative colitis (UC) often occurs in women of childbearing age. Compared to Western countries, however, few studies have investigated the impact of UC on the progress of pregnancy in Asian populations.

Methods: We retrospectively examined 91 pregnancies in 64 patients with UC experienced at our hospital and related institutions from 1991 to 2011, focusing on the relationship between the progression of UC during pregnancy, progress of the pregnancy itself, and the treatment of UC.

The use of lentinan for treating gastric cancer.

Natural compounds containing fungal β-glucans have been used to improve general health for thousands of years in China and Japan. Lentinan, the backbone of β-(1, 3)-glucan with β-(1, 6) branches, is one of the active ingredients purified from Shiitake mushrooms and has been approved as a biological response modifier for the treatment of gastric cancer in Japan. Despite recent advances in chemotherapeutic agents, unresectable or recurrent gastric cancer remains an incurable disease, with survival rates being far from satisfactory.

Lentinan prolonged survival in patients with gastric cancer receiving S-1-based chemotherapy.

Aim: To examine whether administration of lentinan, purified β-1, 3-glucan, can prolong survival in advanced gastric cancer patients receiving S-1-based chemotherapy.

Methods: Since 2004, 78 patients with metastatic or recurrent gastric cancer have received S-1-based chemotherapy as first-line treatment. Survival, side effects, and the ratio of granulocytes/lymphocytes (G/L ratio) were compared between 2 groups of patients who received chemo-immunotherapy using lentinan and chemotherapy alone.

[Investigating the incidence of injection-site reactions associated with administration of oxaliplatin into a peripheral vein and management local adverse reactions].

In Aichi Cancer Center Hospital, we investigated the incidence of injection-site reactions associated with the administration of Oxaliplatin into a peripheral vein. We evaluated the frequency and severity of symptoms, and studied ways to manage its adverse reactions from September 2009 through March 2010. Oxaliplatin was injected into a peripheral vein in more than 90% of patients, suggesting that there would be a high risk of injection-site reactions.

[Pilot study on clinical effects of rebamipide gargle against oral mucositis induced by fluoropyrimidines].

Rebamipide, a cytoprotective agent, has been suspected to attenuate oral mucositis through anti-inflammatory potentials and induction of endogenous prostaglandin synthesis. This prospective study was designed to assess the clinical efficacy of rebamipide gargle against oral mucositis, which is induced by fluoropyrimidines in patients with stomach and colorectal cancer. We first conducted a pilot study on gargle flavors, because the solution in this agent has a strong and bitter after taste.

Irinotecan plus S-1 (IRIS) versus fluorouracil and folinic acid plus irinotecan (FOLFIRI) as second-line chemotherapy for metastatic colorectal cancer: a randomised phase 2/3 non-inferiority study (FIRIS study).

Background: Fluorouracil and folinic acid with either oxaliplatin (FOLFOX) or irinotecan (FOLFIRI) are widely used as first-line or second-line chemotherapy for metastatic colorectal cancer. However, infusional fluorouracil-based regimens, requiring continuous infusion and implantation of an intravenous port system, are inconvenient. We therefore planned an open-label randomised controlled trial to verify the non-inferiority of irinotecan plus oral S-1 (a combination of tegafur, 5-chloro-2,4-dihydroxypyridine, and potassium oxonate; IRIS) to FOLFIRI as second-line chemotherapy for metastatic colorectal cancer.

[Depression screening test for patients with metastatic gastric and colorectal cancer].

The prevalence of depression has been reported to be higher in cancer patients, especially those of advanced stage, compared to normal controls. However, depression is often under-recognized in clinical oncology settings. And this psychological problem is not routinely assessed even in patients with inoperable metastatic cancer who often have psychological disorders.

[Combination therapy of S-1 and 24-h infusion of cisplatin after palliative gastrectomy for stage IV gastric cancer].

We prospectively analyzed the adverse effects and outcomes of 15 patients with stage IV gastric cancer who underwent palliative gastrectomy from December, 2002 to May, 2008 and subsequently received combination therapy of S-1 and 4-h infusion of cisplatin. The National Cancer Institute common toxicity criteria (version 3. 0) were applied to evaluate the adverse effects of this therapy, and the Kaplan-Meier method was used to plot the survival curve.

Relationship between nutritional therapy and surgery in Crohn's disease.

Background/aims: Crohn's disease is often refractory and some patients require repeated surgical treatment. Nutritional therapy with an elemental diet has been reported effective in improving nutritional state and suppressing inflammation, and might be expected to assist in minimizing the need for surgery. We evaluated the relationship between an elemental diet and the period that patients spent without intestinal resection.

[Clinical effects of Hange-shashin-to on combination therapy of S-1/irinotecan against the for patients with metastatic gastric and colorectal cancer].

From July, 2007 to June, 2008, we prospectively investigated the influence of Hange-shashin-to on the therapeutic and adverse effects of chemotherapy and the changes in quality of life(QOL)scores of the patients with metastatic gastric and colorectal cancer. Twenty patients receiving S-1/Irinotecan (CPT-11) therapy were randomly allocated into group A (with Hange-shashin-to) and B (without Hange-shashin-to). While the anti-tumor effects did not differ significantly between these two groups, severe side effects of more than grade 3 occurred less frequently in group A.

[Two advanced gastric cancer cases with peritoneal metastases successfully treated by s-1/paclitaxel combination therapy].

Two unresectable advanced gastric cancer cases with peritoneal metastases were successfully treated by the combination therapy of S-1 and paclitaxel. S-1 (1.25m(2): 80 mg/day, 1.

Helicobacter pylori infection upregulates interleukin-18 production from gastric epithelial cells.

Background: Helicobacter pylori infection induces a biased T helper type 1 (Th1) response that produces IFN-gamma and Fas ligand (FasL). Th1 cytokines are associated with apoptosis in the gastric epithelial cells.

Aim: We aimed to define the role of the recently cloned IL-18, a IFN-gamma inducing factor, in gastric mucosal injury induced by H.

Pathological complete response induced by the combination therapy of S-1 and 24-h infusion of cisplatin in two cases initially diagnosed as inoperable advanced gastric cancer.

We report on two patients, successfully treated by the combination therapy of S-1 and 24-h infusion of cisplatin (CDDP), who were initially diagnosed with unresectable stage 4 advanced gastric cancer. Each patient had a very good clinical response and underwent curative gastrectomy after completion of 14 and 10 courses of S-1/CDDP chemotherapy, respectively. A microscopically detailed examination of surgically obtained specimens showed the complete disappearance of malignant cells in the two cases.
