Ttv vessel
Las tasas de OS a los 5 años con TTVs ≥ 100 mL versus < 100 mL fueron del 41% versus 67% ( P = 0,006) las tasas de RFS respecto a TTVs ≥ 10 mL versus < 10 mL fueron del 14% versus 58% ( P = 0,009). En el anáisis para la RFS, se incluyeron tumores primarios de colon derecho y las metástasis linfáticas primarias un TTV ≥ 10 mL predijo de forma independiente una peor RFS (HR 1,90, i.c. En el análisis multivariable para la OS, se incluyeron los tumores del colon derecho, las metástasis linfáticas primarias y la metástasis hepática bilobar un TTV ≥ 100 mL se asoció de forma independiente con una peor OS (cociente de riesgos instantáneos, hazard ratio, HR, 6,34, i.c. Los valores de corte del TTV para la OS y la RFS fueron de 100 mL y 10 mL, respectivamente. Se identificaron los posibles factores pronósticos y se calcularon la supervivencia global ( overall survival, OS) y la supervivencia libre de recidiva ( recurence-free survival, RFS) mediante análisis multivariados y de Kaplan-Meier. El TTV se estimó a partir de imágenes de tomografía computarizada utilizando un programa de reconstrucción 3D se determinaron los valores de corte mediante un análisis de las características operativas del receptor. Revisión retrospectiva de pacientes a los que se realizó una HR por CRLMs entre 2008 y 2017 en un solo centro. Este estudio analizó el valor pronóstico del TTV en pacientes con CRLMs resecables. Abstract esĪunque el volumen total del tumor (total tumour volume, TTV) puede tener valor pronóstico tras la resección hepática (hepatic resection, HR) en algunas neoplasias sólidas, no se conoce su importancia en las metástasis hepáticas de cáncer colorrectal (colorectal liver metastases, CRLMs). TTV was associated with RFS and OS after initial hepatic resection for CRLM TTV of 100 ml or above was associated with a higher rate of unresectable recurrence.
A TTV of at least 100 ml conferred a higher rate of unresectable initial recurrences (12 of 15, 80 per cent) after initial hepatic resection. Corresponding RFS rates with TTV of 10 ml or more, or less than 10 ml, were 14 and 58 per cent respectively ( P = 0♰09). The 5-year OS rate for a TTV of 100 ml or more was 41 per cent, compared with 67 per cent for a TTV below 100 ml ( P = 0♰06).
Right colonic primary tumours and primary lymph node metastasis were included in the RFS analysis a TTV of 10 ml or more independently predicted poorer RFS (HR 1♹0, 1♱2 to 3♵7 P = 0♰17). Right colonic primary tumours, primary lymph node metastasis and bilobar liver metastasis were included in the multivariable analysis of OS a TTV of 100 ml or above was independently associated with poorer OS (hazard ratio (HR) 6♳4, 95 per cent c.i. TTV cut-off values for OS and RFS were 100 and 10 ml respectively. Potential prognostic factors, overall survival (OS) and recurrence-free survival (RFS) were determined using multivariable and Kaplan–Meier analyses.

TTV was measured from CT images using three-dimensional construction software cut-off values were determined using receiver operating characteristic (ROC) curve analyses.
This was a retrospective review of patients who underwent hepatic resection for CRLM between 20 in a single institution. This study investigated its prognostic value in patients with resectable The latest navigational aids and sensor equipment such as DVLs, USBL Transponders, IMUs, altimeters, CTDs and magnetometers can be included.įront Cross Section: 121.9 cm x 137.Although total tumour volume (TTV) may have prognostic value for hepatic resection in certain solid cancers, its importance in colorectal liver metastases (CRLM) remains unexplored. The system is designed with safety and retrieval capabilities in mind and comes standard with an acoustic release, locator beacon, and xenon flasher. Sensor systems can also be recommended by Teledyne Benthos. The Deep Tow vehicle is configurable to accommmodate customer specified sensors including side scan sonars, multi-beam sonars, and sub bottom profilers. The TTV-190 is a rugged, 6000m rated platform for deep water search, survey, and other data collection operations.
