Six patients with malignant retroperitoneal tumor extending into the inferior vena cava (VCI) were surgically treated with use of a normothermic extracorporeal circulation (ECC). Origin of malignant tumor was renal cancer in four, adrenal cancer in one and seminoma in one. Four patients excluding two of renal cancer had metastasis to the lung or bone preoperatively. One of renal cancer with lung metastasis and invasion to the colon died six months after surgery. The remaining five patients have been alive and well with follow up of 1 year to 7 years (mean 3 years 3 months). Cytological examination of an arterial filter of ECC and intra-circuit blood was made and negative in two patients. Long term results and cytology revealed a rare chance of intraoperative dissemination of malignant cells. These results suggested feasibility of surgery using normothermic ECC for the treatment of malignant retroperitoneal tumor with extension into VCI.

The aim of this study was to evaluate the association between a number of variables and the smokingbehavior of students at 2 medical and 4 nursing schools. Multivariate analysis was applied to clarify theassociation between the Brinkman index and 12 other independent variables.
The study population consisted of 1, 207 medical and 682 nursing students in Japan.
1) 35.4% of medical students (1-6th grades), 12.5% of nursing students and 28.7% of medical students (1-3rd grades) smoked. Medical students in the 5th or 6th grade smoked more frequently than the otherstudents.
2) Smokers in medical school and those giving up smoking in nursing school had more knowledge aboutsmoking and its physical effects than the others.
3) Multiple regression analysis showed that the coefficients of determination for the Brinkman indiceswere 0.197 in medical school (1-6th grades), 0.055 in nursing school and 0.106 in medical schools (1-3rd grades). The main independent variables were age, sex and maternal smoking history.

  In our hospital the palliative care committee has been held once a month since 2000. In 2007, a total of 1,583 cancer patients were admitted to our hospital orreceived medical care at home. The average length of hospital stay was 24 days. Of the total number of patients, 88.4% was informed that they had cancer. In the latter half of the year it increased to 92.6% because the palliative caretakers gave doctors accurate information on patients' psychology and social background. In October 2007 a questionnaire survey was conducted on those who visited our palliative care section on the occasion of the hospital festival. A total of 46 responded to our survey about the knowledge of palliative care, physician's precise explanation about the illness, image of opioids, desirable place of death and so on. Twenty-eight respondents (60.9%) did not know anything about palliative care. Forty-four (95.7%) wanted precise explanation of cancer. Thirty-four (73.9%) said they had had a night image of opioids after reading the panel. Twenty-eight (60.9%) responded they would rather stay at home until death. We should give healthy people more information about palliative care and opioids.

Metabolic syndrome is a long-term complication of systemic chemotherapy for testicular germ cell tumor (TGCT). It is believed to be caused by secondary hypogonadism or toxic medicines because of orchidectomy followed by systemic chemotherapy. In this study, changes in the body composition of patients over time were quantitatively analyzed up to 24 months after chemotherapy. This study retrospectively analyzed 44 patients with TGCT who underwent chemotherapy at our institution from January 2008 to December 2016. Subcutaneous and visceral fat areas and psoas and skeletal muscle areas were measured by computed tomography before and immediately after chemotherapy as well as 3 months, 6 months, 12 months, and 24 months after chemotherapy. The subcutaneous and visceral fat indices and psoas and skeletal muscle indices were calculated as each area divided by body height squared. The total fat area had already significantly increased 3 months after the initiation of chemotherapy (P = 0.004). However, it did not return to prechemotherapeutic levels even at 24 months after chemotherapy. The skeletal muscle area was significantly decreased at the end of chemotherapy (P < 0.001); however, the value returned to baseline within 12 months. In multivariable analysis, the prechemotherapeutic skeletal muscle index and number of chemotherapy cycles were independently associated with the reduction of skeletal muscle at the end of chemotherapy (P = 0.001 and P = 0.027, respectively). In patients with TGCT, skeletal muscle mass decreased during chemotherapy and recovered within 12 months, whereas fat mass progressively increased from the initiation of chemotherapy until 24 months after chemotherapy.
