Objectives: To analyse the decision making for end of life care for patients with cancer at a teaching hospital in Japan at two periods 10 years apart. Design and setting: Retrospective study conducted in a 550 bed community teaching hospital in Okinawa, Japan. Patients: There were 124 terminally ill cancer patients (45 women; 79 men; median age, 69 years) admitted either in 1989 and 1999 for end of life care with sufficient data to permit analysis. Main measurements: Basic demographic data, notification to the patient that he or she had cancer, patient involvement in do not resuscitate (DNR) orders, and various medical interventions which were performed in the month prior to the patient's death were evaluated. Results: In 1989 none of the patients were notified of their diagnosis; in 1999 five patients were informed (p = 0.026). Of the 113 (91%) patients with a written DNR order, none were involved in consenting to the DNR order. In the month before death, patients in both groups received non-palliative treatments such as feeding tube placements (five in 1989; five in 1999), total parenteral nutrition (six in 1989; eight in 1999), and intravenous albumin infusion (four in 1989; five in 1999). Morphine use increased (30%) significantly in 1999 compared with the 1989 group. Conclusions: The majority of patients dying of cancer were still not informed of their diagnosis and were seldom involved in DNR decision making at a teaching hospital in Japan. There was no change in the number of potentially futile interventions that were performed (6-13%) but morphine use increased. Modern ethical education is urgently needed in Japanese medical practice to improve decision making process in the end of life care.

Okinawa Prefecture, located in the subtropics, is an area of endemic adult T-cell leukemia-lymphoma (ATL) in Japan. We retrospectively analyzed 659 patients with aggressive ATL in seven institutions in Okinawa between 2002 and 2011. The median patient age was 68 years. More patients were aged ≥90 years (2.6 %), in this study, than in a nationwide survey (<1 %). The median survival time (MST) of the entire cohort was 6.5 months. Of the 217 patients who had a clinical status similar to that stated in the eligibility criteria of JCOG9801 (a randomized phase III study comparing VCAP-AMP-VECP with CHOP-14), 147 who received the CHOP regimen had a poorer MST than those in the CHOP-14 arm of JCOG9801 (8 vs 11 months). The prevalence of strongyloidiasis in the ATL patients was much higher (12.4 %) than in the historical cohort who visited the University of the Ryukyus Hospital (3.4 %). Furthermore, strongyloidiasis may be associated with ATL-related deaths. These findings suggest that, compared with other areas in Japan, in Okinawa, the proportion of patients aged ≥90 years with clinical features of aggressive ATL is higher, outcomes are poorer, and the disease is associated with a higher prevalence of strongyloidiasis.

This study showed that diabetes itself is a risk factor for greater care resource use after controlling for confounding factors. Pharmacotherapy for breast cancer may influence poor glycemic control, thus leading to greater care resource use. Early detection and careful monitoring of diabetes are essential in malignancy to eliminate this burden on the health care system.
