Estudio de las infecciones relacionadas con la asistencia sanitaria tras la realización de cistectomía radical

Introduction and objectiveRadical cystectomy is a complex surgery with a high rate of complications including infections, which lead to increased morbidity and mortality, longer hospital stay and higher costs. The aim of this work is to evaluate health care-associated infections (HAIs) in these patients, as well as associated microorganisms, antibiotic resistance profiles and risk factors.Material and methodsProspective study from 2012 to 2017. Epidemiologic variables, comorbidities and surgical variables are collected. The microorganisms involved and antibiotic susceptibility patterns are analyzed.Results122 patients. Mean age 67 (SD:18,42). Mean hospital stay 23.5 days (18.42). HAIs rate of 45%, with predominant urinary tract infections (43%) and surgical wound infections (31%). Positive cultures in 78.6% of cases. Increased isolation of Enterococcus (18%) and Escherichia coli (13%). Forty-three percent of microorganisms were resistant to amoxicillin/ampicillin, 23% to beta-lactamases and 36% to quinolones. Empirical treatment was adequate in 87.5%. Hospital stay is increased (17 days, p< 0.05) due to HAIs. Lower rate of infectious complications in the laparoscopic vs. open approach (p< 0.001) and in orthotopic vs. ileal conduit diversion (p = 0.04)ConclusionsWe found a high rate of HAIs in our radical cystectomy series, with predominant urinary tract and surgical wound infections. E.coli and Enterococcus spp. are the most frequently isolated microorganisms, with high rates of resistance to some commonly used antibiotics.     

Utilidad de la quimioterapia neoadyuvante en el carcinoma vesical músculo invasivo no metastásico

ObjectiveWe analyzed the profile of patients who were candidates for neoadjuvant chemotherapy (NACT) in stage pT2-4aN0M0, the tolerability and adherence of our cisplatin-based protocol and oncological outcomes.Material and methodsRetrospective observational cohort study including patients diagnosed with muscle-invasive bladder carcinoma treated with NACT. Clinical, histopathological, therapeutic and evolutionary characteristics of the patients were analyzed. The use of NACT was evaluated by the complete response in the surgical specimen (pT0). This and other pathological factors were related to overall survival and progression-free survival.ResultsWe included 90 patients with muscle-invasive bladder carcinoma (clinical stage T2a-T4aN0M0) who received a cisplatin-based NACT regimen between January 2011 and December 2018, prior to radical surgery. Forty percent of patients presented an adverse reaction, with a compliance with the NACT regimen of 92.2%. There were no deaths related to systemic treatment and no adverse reaction to treatment made radical cystectomy impracticable. After performing radical cystectomy, the presence of complete response (pT0) was observed in 20 patients (21%), lower stage in the surgical specimen (<pT2) in 36 patients (40%), positive surgical margins in 7 patients (8%), lymph node involvement (N1) in 16 patients (17.8%). A shorter time to progression was observed in the group of patients who did not achieve a complete pathological response (53 months vs. 83.1 in pT0 patients, P = 0.012), in patients with lymph node involvement compared to pN0 (65.4 vs. 28, 2 months, P = 0.014) and in those with positive surgical margins compared to those with tumor-free margins (63.5 vs. 8.5 months, P = 0.021).ConclusionThe adequate selection of patients with muscle-invasive bladder carcinoma has shown a good tolerance to NACT, with a high compliance rate prior to RC. The improvement in the complete response rate implies a greater survival in this group of patients, with lymph node involvement and positive surgical margins being important prognostic factors.

Semen analysis and treatment risk factors in long-term survivors of childhood cancer

The objective of this study was to compare semen quality (sperm density, progressive motility and spermia) between long-term childhood cancer survivors and a control group of males. The second objective was to correlate the semen analysis of the survivors with cancer treatment and endocrine status. The semen quality of 143 survivors (median age, 23.6 years) was compared to 200 men (median age, 27.9 years) who had not been diagnosed with cancer. The cancer-related risk factors and gonadotrophin levels were compared. Overall, 65% of the survivors had abnormal semen analysis compared to 26.5% of the controls (p < 0.0001). Survivors with nonaspermia had lower sperm density than the controls (p < 0.001). Other observed correlations were not significant. Survivors who were treated with alkylating agents were more likely to have abnormal semen analysis (p < 0.008). Follicle-stimulating hormone and luteinising hormone levels were significantly elevated (p < 0.0001) in survivors with abnormal semen analysis. The semen quality parameters, except for low sperm density, did not differ in survivors with nonaspermia compared to the controls. The risk factors included treatment with alkylating agents. Elevated gonadotrophin levels correlated with abnormal semen analysis. All cancer survivors should be made aware of the possibility of suffering from cancer treatment-related infertility.
