Open radical cystectomy: still the gold standard for muscle invasive bladder cancer

INTRODUCTION Muscle invasive bladder cancer is an unforgiving disease, and if untreated, it leads to death within 2 years of the diagnosis in >85 % of the patients. Long-term oncologic efficacy remains the ultimate standard that all procedures have to be measured by. In the past decades, open radical cystectomy (RC), extended pelvic lymph node dissection (PLND), and urinary diversion have been established as the gold standard. In the last few years, however, growing attention has been set on robotic-assisted radical cystectomy (RARC). RESULTS Even in the very long term, open RC has good oncological results and if an ileal neobladder is performed excellent functional results. Follow-up of patients after open RC exceeds more than a decade which is unsurpassed by any other technique. Its outcomes have been proven to be durable and cost-effective. Least perioperative complications as well as best oncological and functional results can be achieved if open RC and urinary diversion were performed in a high-volume hospital by high-volume surgeons and an experienced team. CONCLUSIONS Despite upcoming new technologies such as RARC, open RC following extended (PLND) remains the gold standard treatment for high-grade muscle invasive bladder cancer.

There is a place for radical cystectomy and urinary diversion, including orthotopic bladder substitution, in patients aged 75 and older: Results of a retrospective observational analysis from a high-volume center

INTRODUCTION The incidence of cancer increases with age and owing to the changing demographics we are increasingly confronted with treating bladder cancer in old patients. We report our results in patients>75 years of age who underwent open radical cystectomy (RC) and urinary diversion. MATERIAL AND METHODS From January 2000 to March 2013, a consecutive series of 224 old patients with complete follow-up who underwent RC and urinary diversion (ileal orthotopic bladder substitute [OBS], ileal conduit [IC], and ureterocutaneostomy [UCST]) were included in this retrospective single-center study. End points were the 90-day complication rates (Clavien-Dindo classification), 90-day mortality rates, overall and cancer-specific survival rates, and continence rates (OBS). RESULTS Median age was 79.2 years (range: 75.1-91.6); 35 of the 224 patients (17%) received an OBS, 178 of the 224 patients (78%) an IC, and 11 of the 224 patients (5%) an UCST. The 90-day complication rate was 54.3% in the OBS (major: Clavien grade 3-5: 22.9%, minor: Clavien Grade 1-2: 31.4%), 56.7% in the IC (major: 27%, minor: 29.8%), and 63.6% in the UCST group (major: 36.4%, minor: 27.3%); P = 0.001. The 90-day mortality was 0% in the OBS group, 13% in the IC group, and 10% in the UCST group (P = 0.077). The Glasgow prognostic score was an independent predictor of all survival parameters assessed, including 90-day mortality. Median follow-up was 22 months. Overall and cancer-specific survivals were 90 and 98, 47 and 91, and 11 and 12 months for OBS, IC, and UCST, respectively. In OBS patients, daytime continence was considered as dry in 66% and humid in 20% of patients. Nighttime continence was dry in 46% and humid 26% of patients. CONCLUSION With careful patient selection, oncological and functional outcome after RC can be good in old patients. Old age as the sole criterion should not preclude the indication for RC or the option of OBS. In old patients undergoing OBS, satisfactory continence results can be achieved.

How often parametrial involvement leads to post-operative adjuvant treatment in locally advanced cervical cancer after neoadjuvant chemotherapy and type C radical hysterectomy?

OBJECTIVE Parametrial involvement (PMI) is one of the most important factors influencing prognosis in locally advanced stage cervical cancer (LACC) patients. We aimed to evaluate PMI rate among LACC patients undergoing neoadjuvant chemotherapy (NACT), thus evaluating the utility of parametrectomy in tailor adjuvant treatments. METHODS Retrospective evaluation of consecutive 275 patients affected by LACC (IB2-IIB), undergoing NACT followed by type C/class III radical hysterectomy. Basic descriptive statistics, univariate and multivariate analyses were applied in order to identify factors predicting PMI. Survival outcomes were assessed using Kaplan-Meier and Cox models. RESULTS PMI was detected in 37 (13%) patients: it was associated with vaginal involvement, lymph node positivity and both in 10 (4%), 5 (2%) and 12 (4%) patients, respectively; while PMI alone was observed in only 10 (4%) patients. Among this latter group, adjuvant treatment was delivered in 3 (1%) patients on the basis of pure PMI; while the remaining patients had other characteristics driving adjuvant treatment. Considering factors predicting PMI we observed that only suboptimal pathological responses (OR: 1.11; 95% CI: 1.01, 1.22) and vaginal involvement (OR: 1.29 (95%) CI: 1.17, 1.44) were independently associated with PMI. PMI did not correlate with survival (HR: 2.0; 95% CI: 0.82, 4.89); while clinical response to NACT (HR: 3.35; 95% CI: 1.59, 7.04), vaginal involvement (HR: 2.38; 95% CI: 1.12, 5.02) and lymph nodes positivity (HR: 3.47; 95% CI: 1.62, 7.41), independently correlated with worse survival outcomes. CONCLUSIONS Our data suggest that PMI had a limited role on the choice to administer adjuvant treatment, thus supporting the potential embrace of less radical surgery in LACC patients undergoing NACT. Further prospective studies are warranted.

Influence and Impact of Cognitive Trajectories on Outcome in Patients Undergoing Radical Cystectomy: an Observational Study

OBJECTIVES To evaluate cognitive trajectories after radical cystectomy and their impact on surgical outcomes, including urinary continence. METHODS Ninety patients received cognitive testing using the Mini Mental State Exam (MMSE) before open radical cystectomy as well as 3 days and 2 weeks after surgery. Based on MMSE changes ≥3 points between the three time points, five cognitive trajectories emerged (stable cognition, persistent or transient deterioration or persistent or transient improvement). Surgical outcomes were assessed 90 days, 6 months and 1 year postoperatively. RESULTS Mean age was 67.9 ± 9.3 years (range 40 - 88 years). Sixty-six patients (73.3%) had stable cognition, nine patients (10.0%) persistent and seven patients (7.8%) transient deterioration, five patients (5.6%) persistent and three patients (3.3%) transient improvement. An impaired preoperative cognition was the only significant risk factor of short-term cognitive deterioration (OR adjusted for age and sex 9.4, 95%CI 1.6-56.5, p=0.014). Cognition showed no associations with 1-year mortality, 90-day complication rate, cancer progression or duration of in-hospital stay. Patients with transient or persistent cognitive deterioration had an increased risk for nighttime incontinence (OR adjusted for age and sex 5.1, 95%CI 1.1-22.4, p=0.032). CONCLUSIONS In this study, the majority of patients showed stable cognition after major abdominopelvic surgery. Cognitive deterioration occurred in a small subgroup of patients, and an impaired preoperative cognition was the only significant risk factor. Postoperative cognitive deterioration was associated with nighttime incontinence.

Podredumbre radical bacteriana del alcaucil en Mendoza (Argentina)

En alcauciles (Cynara scolymus L.) de la variedad Bleek cultivados en Coquimbito (Mendoza, Argentina) se observó marcada detención del crecimiento y atraso en la formación de las inflorescencias. Las plantas sanas tenían aprox. 1 m de altura mientras las enfermas no llegaban a 30 cm. Las hojas más externas manifestaban clorosis y leve marchitez con posterior necrosis. Se realizaron aislamientos en APG desarrollándose colonias de aspecto mucoso, sobreelevadas, de color castaño claro. También se sembró en medio Kelman base sin TZ desarrollando colonias de iguales características pero con bordes festoneados típicos del género Erwinia. Pruebas bioquímicas y de patogenicidad en invernáculo resultaron positivas. Se identificó a Erwinia carotovora (Jones) Bergey et al. subsp. carotovora Dye, como agente causal de esta podredumbre radical en alcaucil.

Determinación de reducción del crecimiento radical (CE50) por una formulación de glifosato utilizando lechuga y trigo como especies bioindicadoras

El objetivo fue determinar la concentración efectiva media de reducción del crecimiento radical (CE50), de una formulación del herbicida glifosato mediante bioensayos de germinación con semillas de lechuga y de trigo. Para lechuga se probaron 9 dosis/tratamientos decrecientes entre 1.215 y 0,01215 g i.a.ha-1 (formulado: Sal amónica de la N-Fosfonometil glicina, 40,5 [g e.a. glifosato 36,9% p/v]) y para trigo 5 dosis decrecientes (entre 12,15 y 1,215 g i.a.ha-1) y su respectivo control negativo (agua destilada). Se utilizaron cajas de Petri, con papel de filtro en la base humedecido con 3 ml de la solución correspondiente. Se sembraron 20 semillas por caja, distribuyéndose los tratamientos en bloques al azar con 4 repeticiones, en cámara de crecimiento a 20°C con alternancia de luz y oscuridad. Se midió la longitud radicular de todas las semillas de cada tratamiento con calibre digital. Se determinó el porcentaje de germinación y se calculó el índice de germinación. Las CE50, es decir, las dosis que redujeron en un 50% el crecimiento radical para lechuga y trigo, fueron 6,682 y 9,416 g i.a.ha-1, respectivamente. Los materiales probados resultaron sensibles a distintas dosis de glifosato y por lo tanto pueden utilizarse como indicadores biológicos de toxicidad específica.

La juventud radical y la opción por los Frentes Populares [1935-1936]

A mediados de la década del 30, surgió con particular fuerza en nuestro país la idea, claramente inspirada en lo que sucedía en el viejo mundo, de que era necesario conformar un frente de partidos políticos que coordinara la acción conjunta de las fuerzas 'democráticas' que actuaban en Argentina. Guiada por el objetivo de contrarrestar el avance del conservadorismo, la estrategia de los 'Frentes Populares' fue impulsada por sectores provenientes de distintos partidos políticos: es conocido el posicionamiento de fuerte promoción de los Frentes Populares adoptado tanto por el Partido Comunista como por el Partido Socialista. Se sabe mucho menos, en cambio, acerca de aquellos sectores que dentro de la Unión Cívica Radical buscaron insistentemente acercar el radicalismo a otros partidos políticos. En nuestra ponencia analizaremos el apoyo que algunos sectores de la juventud radical dieron a los Frentes Populares; según mostraremos, los jóvenes radicales adhirieron a la política frentista con la expectativa de intervenir más enfáticamente en la coyuntura política nacional, y de operar una transformación al interior del propio radicalismo

Catherine Mackinnon, el feminismo radical y la pornografía

Este trabajo es el fruto de los debates que mantuvimos en el Seminario sobre Violencia de Género, a cargo del Dr. Hendler, en el Instituto Gioja, de la UBA, y es a ellos -a todos sus miembros- que les estamos agradecidos. El debate en torno de la pornografía -como forma de violencia y de acoso- es un debate muy amplio, quisimos reflejar aquí, meramente, una perspectiva: la del feminismo radical. También quisimos ver cómo la pornografía se conecta con otra cuestión gravosa para las mujeres: la violencia doméstica
