Comparative StudyComparison of robotic-assisted versus retropubic radical prostatectomy performed by a single surgeon.
To compare perioperative outcomes between patients undergoing robotic-assisted laparoscopic radical prostatectomy (RALP) and patients undergoing retropubic radical prostatectomy (RRP) performed by a single surgeon in Taiwan. ⋯ RALP is minimally invasive with less blood loss and lower transfusion rates than RRP. RALP had greater incidence of neurovascular bundle preservation and faster convalescence than RRP.

Lymph-vascular space involvement and outer one-third myometrial invasion are strong predictors of distant haematogeneous failures in patients with stage I-II endometrioid-type endometrial cancer.
The aim of this retrospective study was to assess the predictive value of different clinicopathological variables (patient age, tumour size, FIGO grade, myometrial invasion, lymph-vascular space involvement [LVSI], invasion margins, peri-tumour phlogistic infiltrate and mitotic activity) for the risk of distant haematogenous recurrences in patients with endometrioid-type stage Ib-II endometrial cancer. Between August 1990 and April 2005, 259 patients had undergone laparotomy, peritoneal washing, total abdominal hysterectomy and bilateral salpingo-oophorectomy, with or without pelvic +/- para-aortic lymphadenectomy for endometrioid-type endometrial cancer. Thirty-six (13.9%) patients had developed recurrent disease after a median time of 17 months (range, 2-128 months). ⋯ On univariate analysis, a higher incidence of FIGO grade 3 (50% versus 10%, p=0.0114), outer one-third myometrial invasion (91.7% versus 35.0%, p=0.0051) and LVSI (75.0.% versus 20.0%, p=0.0022) was found in the patients who had developed distant haematogeneous metastases compared to the recurrence-free women. Multivariate analysis showed that LVSI (p=0.0264) and deep myometrial invasion (p=0.0345) were independent predictive variables for the risk of distant haematogeneous failure. Patients with these pathological findings should be enrolled in randomised trials designed to assess the role of adjuvant chemotherapy alone or combined with sequential and/or concomitant external pelvic irradiation.

Clinical outcomes of unrelated donor umbilical cord blood transplantation for 30 adults with hematological malignancies.
Umbilical cord blood transplantation (CBT) has increasingly been used as a therapeutic option for adult patients for whom allogeneic stem-cell transplantation is not indicated, due to the availability of cord blood. However, myeloablative conditioning regimens are associated with significant mortality, and high relapse rates in reduced-intensity regimens may result in a poor rate of disease-free survival for those with advanced stages of hematological malignancies. Therefore, it remains unknown whether CBT is a truly effective option for such adults with high-risk disease, as well as for those with standard-risk disease. ⋯ Although from a retrospective study, these results suggest that unrelated donor CBT could be safe and effective for adult patients with standard-risk disease who cannot find a suitable HLA-matched volunteer marrow or peripheral blood donor.
