Adenoma-carcinoma Sequence in the Bladder After Augmentation Cystoplasty

AbstractWe present a case of a 64-year-old woman showing multistep progression from adenoma to adenocarcinoma in the bladder 46 years after augmentation ileocystoplasty. She underwent augmentation ileocystoplasty for tuberculous contracted bladder at 18 years. After 44 years, tubulovillous adenomas were found and resected at the ileovesical anastomosis site. After 2 more years, bladder tumors recurred and revealed adenocarcinomas. Finally, radical cystectomy was required because of frequent recurrence and tumor extensiveness. To our knowledge, this is the first case demonstrating adenoma-carcinoma sequence histopathologically in the bladder after augmentation cystoplasty, indicating multistep carcinogenesis similar to intestinal carcinogenesis

A Report on Overseas Teaching Practicum by Graduate Students in Elementary/Secondary Schools in the United States (Ⅶ)

The present reports is on the 7th overseas teaching practicum in the United States by 15 graduate students of Hiroshima University, Japan, partly organized by Hiroshima University Global Partnership School Center since 2007. The group was comprised of 13 elementary school and 2 secondary school education major graduate students. They planned and conducted lessons in English in three local public schools in North Carolina. The expected outcomes of this project were: 1) to self-develop practical instructional competence by teaching pupils with diverse backgrounds in the U.S.; 2) to enhance the abilities in developing teaching materials through hands-on teaching experiences in English; and 3) to acquire the abilities to design, implement and evaluate programs for promoting global partnership. In addition, the teaching experience was followed by cross-cultural study visits to Raleigh, NC and Washington, D.C. It helped to boost our group motivation that the local media, newspaper and TV, and the city Board of Education covered our visit. It is hoped that this project will enhance the students’ teaching competence in designing quality materials/lessons and classroom communication skills in English

Comparison of perioperative outcomes in elderly (age ≧ 75 years) vs. younger men undergoing robot-assisted radical prostatectomy.

OBJECTIVES:To investigate perioperative, oncologic, and functional outcomes of robot-assisted radical prostatectomy (RARP) in men of age ≥ 75 years in comparison with younger men. METHODS:From November 2011 to December 2018, six hundred and thirty patients with prostate cancer underwent robot-assisted radical prostatectomy (RARP). A total of 614 patients were analyzed after excluding 16 patients who were treated with hormone therapy prior to RARP. Patients were divided into 2 groups based on their age (age ≥ 75 years: N = 46 patients and age < 75 years: N = 568 patients). Perioperative parameters regarding oncologic/functional outcomes and complication status were compared between the 2 groups. Clavien-Dindo classification was used to classify perioperative complications. Clinical and pathological status including stage, positive margin, continence, and potency status after RARP were analyzed. RESULTS:Five-hundred sixty-eight and forty-six men were of age <75 and ≥ 75 years, respectively. There were no significant differences between the 2 groups in terms of oncologic outcomes (positive resection margin rate and PSA failure). The duration of hospitalization was longer in older patients but was not statistically significant (P = 0.051). A total number of Clavien ≥3 complications that occurred within a month after RARP were 15 (2.6%) and 2 (4.3%) in younger men (age < 75 years) and older men (age ≥ 75 years), respectively (P = 0.359). CONCLUSION:The present study showed that the oncologic and surgical outcomes in the elderly group were similar to those in the younger population. However, the duration of hospitalization seemed to be longer in older patients (age ≥ 75 years), despite similar complication rates

The therapeutic potential of multiclonal tumoricidal T cells derived from tumor infiltrating lymphocyte-1derived iPS cells

Ito et al. generated and characterized multiclonal tumoricidal T cells derived from tumor infiltrating lymphocyte-derived iPS cells (TIL-iPSC) using human colorectal cancer specimens. They demonstrated that the newly-generated T cells retained intrinsic characters and acquired improved functions with less differentiated profiles, thus constituting a potential therapeutic anti-cancer tool
