Radiofrequency ablation for solitary metastasis is associated with a markedly higher LR rate and shorter recurrence-free and overall survival rates compared with HR, even when small lesions (< or = 3 cm) are considered. Every method should be considered to achieve resection of solitary colorectal liver metastasis, including referral to a specialty center, extended hepatectomy, and chemotherapy.PMID: [PubMed - indexed for MEDLINE]Solitary colorectal liver metastasis: resection determines outcome.Aloia TA,Vauthey JN,Loyer EM,Ribero D,Pawlik TM,Wei SH,Curley SA,Zorzi D,Abdalla EK.Department of Surgical Oncology, The University of Texas M.

Moreover, curative liver resection of colorectal liver metastases is the only treatment offering a chance of long-term survival. Unfortunately, the liver resection can be performed in only 10% of the patients. AIM: In order to extend the frontiers of surgical indications in the treatment of liver metastases from colorectal cancer, we describe, in the video, a multimodal approach to rectal cancer with liver metastasis in the right lobe. Patient and methods. A 51 years old woman was admitted to our Department for adenocarcinoma of the distal rectum and a resectable solitary synchronous liver metastasis located across the right and the middle hepatic vein. Unfortunately, the future remnant liver was too small, risking severe post-operative liver failure. For this reason, a portal vein embolization or occlusion has been proposed. First of all, the patient has been submitted to laparoscopic low anterior resection with simultaneous right portal vein ligature. Two months later, after a CT estimation of liver volume in vivo, she was submitted to right hepatectomy (open surgery). RESULTS: Both postoperative courses were uneventful. CONCLUSIONS: As a preparation for large hepatic resection for liver rectal metastasis the laparoscopic ligature of the right portal vein performed simultaneously to the laparoscopic low anterior resection is feasible and safe.PMID: [PubMed - indexed for MEDLINE]· Df The morbidity rates and mortalities reported after repeat hepatectomy for metastatic colorectal cancer92–104 and hepatocellular carcinoma105–112 are comparable to those reported after initial hepatectomy.92.

The aims of this study were to review our experience with synchronous colorectal metastasis and to define the safety of simultaneous versus staged resection of the colon and liver.Study designFrom September 1984 through November 2001, 240 patients were treated surgically for primary adenocarcinoma of the large bowel and synchronous hepatic metastasis. Clinicopathologic, operative, and perioperative data were reviewed to evaluate selection criteria, operative methods, and perioperative outcomes.ResultsOne hundred thirty-four patients underwent simultaneous resection of a colorectal primary and hepatic metastasis in a single operation (Group I), and 106 patients underwent staged operations (Group II). Simultaneous resections tend to be performed for right colon primaries (p < 0.001), smaller (p < 0.01) and fewer (p < 0.001) liver metastases, and less extensive liver resection (p < 0.001). Complications were less common in the simultaneous resection group, with 65 patients (49%) sustaining 142 complications, compared with 71 patients (67%) sustaining 197 complications for both hospitalizations in the staged resection group (p < 0.003). Patients having simultaneous resection required fewer days in the hospital (median 10 days versus 18 days, P = 0.001). Perioperative mortality was similar (simultaneous, N = 3; staged, N = 3).ConclusionsSimultaneous colon and liver resection is safe and efficient in the treatment of patients with colorectal cancer and synchronous liver metastasis. By avoiding a second laparotomy, the overall complication rate is reduced, with no change in operative mortality. Given its reduced morbidity, shorter treatment time, and similar cancer outcomes, simultaneous resection should be considered a safe option in patients with resectable synchronous colorectal metastasis.
2 Ressecção de Metástase Hepática de origem colorretal 50 % dos pacientes com câncer colorretal irão desenvolver metástases hepáticas em algum período de sua doençaSurgical strategies for colorectal liver metastasesSurgical Oncology - Vol 13, I 2-3 , Aug-Nov 2004, PagLesão sincrônica ( 15 a 20%) x lesão metacrônica ( 25 a 50%)Após ressecção:Sobrevida média de 30 a 40 mesesSobrevida em 5 anos: 38 % ( NCCN )São elegíveis apenas 20 a 25 % dos pacientesColorectal cancer remains the second commonest cause of death from cancer in Western society. Nearly half of all patients will develop liver metastases and many will die with disease confined to the liver. The accepted modern definitions of resectability now mean that over twenty per cent of patients are now resectable (with operative mortality of >2%) with curative intent, and nearly one third will be alive, disease free, five years later. The use of additional techniques such as radiofrequency ablation may bring many more patients the possibility of long term survival. The introduction of new chemotherapy regimens, including those based on oxaliplatin may convert one third of non-resectable patients to resectability with curative intent. Therefore, in 2004 nearly one third of patients with disease confined to the liver can now look forward to possibly curative liver surgery.Synchronous versus metachronous diseaseMetachronous, as opposed to synchronous, detection of colorectal metastases following diagnosis of the primary tumour usually carries a slightly more favourable prognosis; consistent with the likelihood that disease was less advanced when the initial diagnosis was made ,  and . Importantly however, a multicentre retrospective study of over 1800 patients found no significant difference in the proportion of short and long-term survivors after surgery between patients whose metastases were detected synchronously or metachronously . Several other studies have shown that when analysed by multivariate analysis, the prognosis after resection is not dependent on the time of detection of metastatic disease , ,  and . In interpreting data concerning the benefits of resection of metachronous versus synchronous metastases, consideration should be given to progress in methods of earlier detection.
