ABSTRACT

BACKGROUND: Patients with metastatic colorectal cancer (mCRC) carrying BRAF (mutBRAF) or KRAS mutation (mutKRAS) have an inferior prognosis after liver or lung surgery, whereas the prognostic role in the context of peritoneal metastasis (PM) after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has been less investigated. METHODS: In total, 257 patients with non-appendiceal PM-CRC were included from the Norwegian National Unit for CRS-HIPEC. RESULTS: In total, 180 patients received CRS-HIPEC with Mitomycin C, 77 patients received palliative surgery only. In the CRS-HIPEC group, mutBRAF was found in 24.7%, mutKRAS 33.9% and double wild-type 41.4% without differences in survival. MSI was found in 29.3% of mutBRAF cases. Patients with mutBRAF/MSI had superior 5-year survival compared to mutBRAF with MSS (58.3% vs 25.2%, P = 0.022), and better 3-year disease-free survival (DFS) compared to mutKRAS (48.6% vs 17.2%, P = 0.049). Peritoneal Cancer Index and the number of lymph node metastasis were prognostic for OS, and the same two, location and gender prognostic for DFS in multivariate analysis. CONCLUSIONS: PM-CRC with CRS-HIPEC patients has a surprisingly high proportion of mutBRAF (24.7%). Survival was similar comparing mutBRAF, mutKRAS and double wild-type cases, whereas a small subgroup with mutBRAF and MSI had better survival. Patients with mutBRAF tumours and limited PM should be considered for CRS-HIPEC.

ABSTRACT

BACKGROUND: Most treatments for cancer cause a decline in patients' health-related quality of life (HRQoL). Limiting this decline is a universal goal for healthcare providers. Using minimally invasive instead of open surgical techniques might be one way to achieve this. The aim of this study was to compare postoperative HRQoL after open and laparoscopic liver resection. METHODS: This was a predefined substudy of an RCT comparing open with laparoscopic liver resection. Patients with colorectal liver metastases were assigned randomly to open or laparoscopic parenchyma-sparing liver resection. HRQoL was assessed with the Short Form 36 questionnaire at baseline, and 1 and 4 months after surgery. RESULTS: A total of 280 patients were randomized, of whom 273 underwent surgery (129 laparoscopic, 144 open); 682 questionnaires (83.3 per cent) were available for analysis. One month after surgery, patients in the laparoscopic surgery group reported reduced scores in two HRQoL domains (physical functioning and role physical), whereas those in the open surgery group reported reduced scores in five domains (physical functioning, role physical, bodily pain, vitality and social functioning). Four months after surgery, HRQoL scores in the laparoscopic group had returned to preoperative levels, whereas patients in the open group reported reduced scores for two domains (role physical and general health). The between-group difference was statistically significant in favour of laparoscopy for four domains after 1 month (role physical, bodily pain, vitality and social functioning) and for one domain after 4 months (role physical). CONCLUSION: Patients assigned to laparoscopic liver surgery reported better postoperative HRQoL than those assigned to open liver surgery. For role limitations caused by physical health problems, patients in the laparoscopic group reported better scores up to 4 months after surgery. Registration number: NCT01516710 ( http://www.clinicaltrials.gov).


ANTECEDENTES: La mayoría de los tratamientos para el cáncer causan una disminución de la calidad de vida relacionada con la salud (health-related quality of life, HRQoL) de los pacientes. Limitar este declive es un objetivo universal para los proveedores de atención médica. El uso de técnicas quirúrgicas mínimamente invasivas en lugar de abiertas podría ser una forma de lograrlo. El objetivo de este estudio fue comparar la HRQoL postoperatoria después de la resección hepática abierta y laparoscópica. MÉTODOS: Se trata de un subestudio predefinido de un ensayo aleatorizado y controlado que comparó la resección hepática abierta con la laparoscópica. Los pacientes con metástasis hepáticas colorrectales se asignaron aleatoriamente al grupo de resección hepática con preservación de parénquima por vía abierta o por vía laparoscópica. La HRQoL se evaluó con el cuestionario abreviado SF-36 en el momento basal y al cabo de 1 y 4 meses después de la cirugía. RESULTADOS: Un total de 280 pacientes fueron aleatorizados, de los cuales 273 se sometieron a cirugía (129 = laparoscópica, 144 = abierta) y hubo 682 cuestionarios (83%) disponibles para el análisis. Un mes después de la cirugía, los pacientes del grupo de cirugía laparoscópica presentaron puntuaciones reducidas en dos items de HRQoL (función física y rol físico), mientras que los pacientes del grupo de cirugía abierta presentaron puntuaciones reducidas en cinco items (función física, rol físico, dolor corporal, vitalidad y función social). Cuatro meses después de la cirugía, el grupo de cirugía laparoscópica había vuelto a los niveles preoperatorios de la HRQoL, mientras que los pacientes del grupo de cirugía abierta presentaron puntuaciones reducidas para dos items (función física y salud general). La diferencia entre los grupos fue estadísticamente significativa a favor de la laparoscopia para cuatro items después de un mes de la cirugía (rol físico, dolor corporal, vitalidad y función social) y para un ítem (rol físico) después de cuatro meses. CONCLUSIÓN: Los pacientes asignados a cirugía hepática laparoscópica presentaron mejor HRQoL postoperatoria que los pacientes asignados a cirugía hepática abierta. Para las limitaciones de roles causadas por problemas físicos de salud, los pacientes de cirugía laparoscópica presentaron mejores puntuaciones a los cuatro meses tras la intervención quirúrgica.
