- Introduction: Several studies have demonstrated a decreased overall survival for patients with muscle-invasive bladder cancer (MIBC) receiving allogenic peri- and postoperative blood transfusions at cystectomy. However, the extent and the effect of blood transfusions given during neoadjuvant chemotherapy (NAC) has never been addressed. The purpose of the present study, was to assess the impact of blood transfusions given during NAC on survival in patients with MIBC undergoing NAC and radical cystectomy.Materials and Methods: A cohort of 120 consecutive patients with MIBC (cT2-T4aN0M0) undergoing NAC and radical cystectomy at four Swedish centers was retrospectively evaluated. Clinical and pathoanatomical data was obtained, including data SCANDINAVIAN JOURNAL OF UROLOGY 35 on administeredallogenic blood at consecutive time-intervals. Overall survival was analyzed by Kaplan-Meier plotting and Cox regression.Results: One third of the cohort (n ¼ 40) received blood transfusions during NAC-therapy. The five-year overall survival rates were significantly lower in this group compared to the non-transfused patients (39.7% and 58.9% respectively, p ¼ 0.047). In a univariate analysis, blood transfusions, nodal status and locally advanced tumor growth (pT >2), were negative prognostic factors for survival. In multivariate analysis, only pNx and pT >2 remained significant negative prognostic factors. In subgroup analysis of localized and non-disseminated patients only (n ¼ 96), blood transfused patients showed a 18,5% absolute risk increase compared to blood naïve patients (p¼ 0.197).Conclusions: This is the first time that the extent and the effect of allogenic blood transfusions during NAC is examined in MIBC. Data suggest that there may be an association between blood transfusion and poor pathological and oncological outcome. Firm conclusions are difficult to draw due to the limited number of study participants and the retrospective nature of the study.

- Objective: To evaluate the extent and plausible effects of blood transfusions given during cisplatin-based neoadjuvant chemotherapy (NAC) on overall survival in patients with muscle-invasive urothelial bladder cancer (MIBC) undergoing NAC and radical cystectomy (RC).Background: Several studies have demonstrated a decreased survival for MIBC patients receiving allogenic peri- and postoperative blood transfusions in conjunction with RC. No studies have previously investigated the effects of blood transfusions during NAC.Materials and methods: 120 patients with MIBC (cT2-T4aN0M0) undergoing NAC and RC between 2008 and 2014 at four Swedish cystectomy centers were retrospectively evaluated. Clinicopathological data were obtained, including data of allogenic blood administration. Survival data was analyzed by Kaplan–Meier plotting and Cox regression.Results: One third of the cohort received blood transfusions during the period of NAC. In univariate analysis, blood transfusions during NAC, nodal stage and advanced tumor stage (pT >2) were negative prognostic factors for survival. In multivariate analysis, only pNx and pT >2 remained significant negative prognostic factors. In a subgroup analysis consisting of patients with localized tumors without dissemination (n = 96), patients that received transfusions during NAC showed an 18.5% absolute risk increase of death at five years of observation, although without statistical significance (p = .197).Conclusions: This is the first time that the extent and plausible effects of allogenic blood transfusions during NAC is examined in MIBC. Data suggest that there may be an association between blood transfusion and poor pathological and oncological outcome. Firm conclusions are difficult to draw due to few study participants and the retrospective nature of the study.

- OBJECTIVE: The aim of this study was to determine by computed tomography (CT) whether treatment with tumor-draining lymph-node-derived expanded autologous T lymphocytes results in objective responses and/or improved survival in patients with metastatic urinary bladder cancer (UBC) and to record the toxicity of the treatment.MATERIALS AND METHODS: Eighteen patients with metastatic UBC were prospectively selected from two centers. The preoperative staging was T2-T4bN1-2 and/or M0-M1 or MX. Tumor-draining lymph nodes were harvested at intended cystectomy for the extraction of T lymphocytes. This was followed by expansion of the T lymphocytes in a cell culture, and subsequent reinfusion of these autologous tumor-specific T lymphocytes. Responses to therapy were evaluated by CT scans according to Response Evaluation Criteria In Solid Tumors (RECIST) and clinical follow-up, according to the research protocol.RESULTS: Nine out of 18 patients were treated. Treatment was feasible and safe. In two out of nine immunologically treated patients, objective responses were detected in terms of diminished or obliterated nodal metastases. When excluding three patients with disseminated osseous metastases plus one with a T4b tumor left in situ, a success rate of two out of six treated patients was seen. The two responders had survival times of 35 and 11 months, respectively. No toxicity was recorded.CONCLUSIONS: Infusion of expanded autologous tumor-specific T lymphocytes is feasible and safe, and objective responses according to RECIST were recorded. One objective responder to immunotherapy displayed notably long overall survival.
