[Collision cancer of primary squamous cell carcinoma and adenocarcinoma in the stomach after treatment for a non-Hodgkin's lymphoma of diffuse large B cell type:a case report].

We report the case of a 61-year-old woman with a collision cancer of primary squamous cell carcinoma (SCC) and adenocarcinoma in the stomach that was cured surgically. She achieved complete remission after treatment (R-CHOP and radiation therapy;40.8Gy/22Fr) for a non-Hodgkin's lymphoma of diffuse large B cell type from September 2016 to April 2017.

A new once-a-day fentanyl citrate patch (Fentos Tape) could be a new treatment option in patients with end-of-dose failure using a 72-h transdermal fentanyl matrix patch.

Purpose: The recommended dosing interval for transdermal fentanyl is every 72 h. However, some patients will have "end-of-dose failure," which may be seen as an increase of episodes of severe pain flares at the third day after application of the patch. A new once-a-day fentanyl patch was developed in Japan since 2010.

Effect of duloxetine in Japanese patients with chemotherapy-induced peripheral neuropathy: a pilot randomized trial.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is difficult to manage. A phase III trial conducted in the United States demonstrated that duloxetine was effective for CIPN caused by taxane and platinum-based chemotherapy. No randomized trial of duloxetine for CIPN has been conducted in Japan.

A survey of patients who were referred to our palliative care division from other hospitals and appeared to have obvious indications for cancer chemotherapies.

Higashi Sapporo Hospital is a cancer-specific hospital with palliative care doctors and certified oncologists. During case conferences held twice a week, we routinely evaluate the referred patients. In our case conferences, we selected patients who were referred to our palliative care division from other hospitals, with possible indications for cancer chemotherapies.

Recent advances in palliative cancer care at a regional hospital in Japan.

More than 30 years have passed since the introduction of the concept of palliative care in cancer care in Japan. However, the majority of the estimated three million cancer patients in Japan do not receive palliative care. Higashi Sapporo Hospital was established in 1983 as a hospital specialized in cancer care.

The Effects of Percutaneous Endoscopic Gastrostomy on Quality of Life in Patients With Dementia.

Background: To examine the effects of percutaneous endoscopic gastrostomy (PEG) on quality of life (QOL) in patients with dementia.

Methods: We retrospectively included 53 Japanese community and tertiary hospitals to investigate the relationship between the newly developed PEG and consecutive dementia patients with swallowing difficulty between Jan 1st 2006 and Dec 31st 2008. We set improvements in 1) the level of independent living, 2) pneumonia, 3) peroral intake as outcome measures of QOL and explored the factors associated with these improvements.

The sky blue method as a screening test to detect misplacement of percutaneous endoscopic gastrostomy tube at exchange.

Background: During tube exchange for percutaneous endoscopic gastrostomy (PEG), a misplaced tube can cause peritonitis and death. Thus, endoscopic or radiologic observation is required at tube exchange to make sure the tube is placed correctly. However, these procedures cost extensive time and money to perform in all patients at the time of tube exchange.

Covering the percutaneous endoscopic gastrostomy (PEG) tube prevents peristomal infection.

Background: Because oropharyngeal bacteria can be brought through the abdominal wall during percutaneous endoscopic gastrostomy (PEG), peristomal infection is one of the most frequent complications in patients who undergo the procedure. This study aimed to determine whether covering the PEG tube with a sheath that could be detached in the stomach could help prevent peristomal infection.

Methods: In three community hospitals in Japan, data from 449 patients with swallowing dysfunction were prospectively collected between March 2000 and February 2002 for non-covered PEG (n=206) and between March 2002 and February 2004 for covered PEG (n=243).

Thrombopoietin concentrations in peripheral blood correlated with platelet numbers in two patients with thrombocytopenia by chronic graft-versus-host disease.

Thrombocytopenia is well known to be one of the clinical manifestations of chronic graft-versus-host disease (cGVHD). However, there exist cases in which the cause of thrombocytopenia has been unexplained. Recently, thrombopoietin (TPO) from bone marrow (BM) stromal cells and transforming growth factor (TGF)-beta from platelets and megakaryocytes have been identified as strong positive and negative regulators of megakaryopoiesis in vivo.

Granulocyte-colony stimulating factor enhances the expression of transforming growth factor-beta mRNA in CD4-positive peripheral blood lymphocytes in the donors for allogeneic peripheral blood stem cell transplantation.

The degree of acute graft-versus-host disease (GVHD) after allogeneic peripheral blood stem cell transplantation (allo-PBSCT) has been observed to be, unexpectedly, of an equal level to that after bone marrow transplantation. To explain this phenomenon, we hypothesized that granulocyte-colony stimulating factor (G-CSF) administration may induce transforming growth factor (TGF)-beta producing T cells in the donors. Five donors received 10 microg/kg G-CSF subcutaneously for 4 days.
