RESUMEN
PURPOSE: In Japan, there have been no national surveys on the incidence of de novo malignancy after solid organ transplantation, which is one of the leading causes of death in transplant recipients. METHODS: A questionnaire was distributed to institutions that perform solid organ transplantation in Japan, and clinical information was collected from patients who underwent transplantation between 2001 and 2010 and who exhibited de novo malignancies. RESULTS: Nine thousand two hundred ten solid organ transplants (kidney, 49.9%; liver, 45.9%; heart, 0.9%; lung, 1.2%; pancreas, 1.9%; small intestine, 0.2%) were performed. Four hundred seventy-nine (5.2%) cases of de novo malignancy were identified. The transplanted organs of the patients included the kidney (n = 479, 54.8%), liver (n = 186, 38.8%), heart (n = 5, 0.1%), lung (n = 18, 3.8%), pancreas (n = 9, 1.9%), and small intestine (n = 1, 0.02%). The most common malignancies were post-transplant lymphoproliferative disorder (n = 87) and cancers of the kidney (n = 43), stomach (n = 41), large intestine (n = 41), and lung (n = 36). CONCLUSIONS: This is the first national survey of the incidence of de novo malignancy in Japan. Further study is required to identify the risk of de novo malignancy in organ transplant recipients in comparison to the general population, namely the standardized incidence ratio.

OBJECTIVE: Uterus transplantation (UTx) is a potential option for women with uterine factor infertility to have a child, but there has been no large-scale survey of the views on UTx in women of reproductive age in Japan. The present study was aimed to clarify the views of Japanese women of reproductive age on UTx for uterine factor infertility. METHODS: A questionnaire on UTx was conducted by an Internet research company in December 2014 as a cross-sectional study in 3,892 randomly chosen women aged 25 to 39 years old. Responses were analyzed from 3,098 subjects (mean age 32.1±4.2 years old), after exclusion of inappropriate respondents in screening. RESULTS: Of the respondents, 62.1%, 34.7% and 18.1% favored adoption, UTx and gestational surrogacy, respectively. In contrast, 7.0%, 21.9% and 63.3% opposed adoption, UTx and gestational surrogacy, respectively. In choices of candidates for UTx based on highest priority, deceased persons (33.8%) and mothers (19.0%) were favored as donors, and women with congenital absence of the uterus (54.4%) and hysterectomy due to a malignant uterine tumor (20.0%) as recipients. Regarding societal acceptance of UTx, the answer rates were 15.7% for "UTx should be permitted", 77.6% for "UTx should be permitted with discussion", and 6.7% for "UTx should not be permitted, even with discussion". Regarding personal opinions on UTx, 44.2% were in favor, 47.5% had no opinion, and 8.3% were against. CONCLUSION: Our results suggest that many Japanese women of reproductive age feel that UTx is socially and individually acceptable, but that concerns requiring further discussion remain among these women. There was also a tendency for UTx to be viewed more favorably than gestational surrogacy.

Transplantation in Japan, as well as the environment in which nurses work, has been slowly changed. Consequently, those nurses started working as recipient coordinators to meet the needs of patients, physicians and nurses who work at the patients' bedside. In the future, recipient coordinators can be a valuable asset to each transplant program because of their education, commitment to personalized care to recipients and their families. This article describes a variety of roles of recipient coordinators in Japan.
