We studied 141 patients who had resection of hepatic metastases from colorectal cancer, considering all such lesions removed between 1948 and 1982. The study involved extended observations of patients described previously. Also included were 21 patients who had wedge resections of small metastases done since 1976, who, therefore, did not qualify for analysis of major hepatic resections reported recently (1980 and 1983). The overall five-year survival rate was 25%, significantly higher than that of a group of historical controls who had resectable metastases that were not removed. The size and nature of our extended sample allowed identification of some determinants of favorable prognosis: Dukes' stage of the primary lesion, absence of extrahepatic metastases, and being female. Contrary to our earlier observations, this study justified removal of some multiple hepatic metastases.

    • "Limitations remain as only about 10–20% of patients with liver metastatic disease are candidates for surgical resection at presentation [11]. However, another 15–30% of previously considered unresectable patients can be converted and (despite the absence of randomized controlled trials) the majority of evidence supports a significant survival benefit with surgical resection, with overall 5-year survival rates after hepatic resection with curative intent ranging from 35 to 55% [12–16].

    ABSTRACT: In the last few decades there have been significant changes in the approach to rectal cancer management. A multimodality approach and advanced surgical techniques have led to an expansion of the treatment of metastatic disease, with improved survival. Hepatic metastases are present at one point or another in about 50% of patients with colorectal cancer, with surgical resection being the only chance for cure. As the use of multimodality treatment has allowed the tackling of more complicated cases, one of the main questions that remain unanswered is the management of patients with synchronous rectal cancer and hepatic metastatic lesions. The question is one of priority, with all possible options being explored. Specifically, these include the simultaneous rectal cancer and hepatic metastases resection, the rectal cancer followed by chemotherapy and then by the liver resection, and finally the "liver-first" option. This paper will review the three treatment options and attempt to dissect the indications for each. In addition, the role of laparoscopy in the synchronous resection of rectal cancer and hepatic metastases will be reviewed in order to identify future trends.

    • "Recurrence rates after resection of liver metastases are high however, and there is significant associated morbidity and mortality. Surgical treatment offers 5-year survival rates of 25% to 37% and 10-year survival rates of 20% [35–37]. "

    ABSTRACT: Colorectal cancer is the third most commonly diagnosed cancer, accounting for 53,219 deaths in 2007 and an estimated 146,970 new cases in the USA during 2009. The combination of FDG PET and CT has proven to be of great benefit for the assessment of colorectal cancer. This is most evident in the detection of occult metastases, particularly intra- or extrahepatic sites of disease, that would preclude a curative procedure or in the detection of local recurrence. FDG PET is generally not used for the diagnosis of colorectal cancer although there are circumstances where PET-CT may make the initial diagnosis, particularly with its more widespread use. In addition, precancerous adenomatous polyps can also be detected incidentally on whole-body images performed for other indications; sensitivity increases with increasing polyp size. False-negative FDG PET findings have been reported with mucinous adenocarcinoma, and false-positive findings have been reported due to inflammatory conditions such as diverticulitis, colitis, and postoperative scarring. Therefore, detailed evaluation of the CT component of a PET/CT exam, including assessment of the entire colon, is essential.

    • "In rectal cancer patients with liver metastasis, conservative management including diverting colostomy resulted in a median survival of approximately three to five months, while resection of the primary tumor increased median survival to fourteen to twenty-four months [4-6]. Resection of both the primary and metastatic liver tumors resulted in a median survival of thirty-seven months and a five-year survival rate of 25-35% [7,8]. "

    ABSTRACT: Synchronous liver metastases are detected in approximately 25% of colorectal cancer patients at diagnosis. The rates of local failure and distant metastasis are substantial in these patients, even after undergoing aggressive treatments including resection of primary and metastatic liver tumors. The purpose of this study was to determine whether adjuvant pelvic radiotherapy is beneficial for pelvic control and overall survival in rectal cancer patients with synchronous liver metastasis after primary tumor resection. Among rectal cancer patients who received total mesorectal excision (TME) between 1997 and 2006 at Yonsei University Health System, eighty-nine patients diagnosed with synchronous liver metastasis were reviewed. Twenty-seven patients received adjuvant pelvic RT (group S + R), and sixty-two patients were managed without RT (group S). Thirty-six patients (58%) in group S and twenty patients (74%) in group S+R received local treatment for liver metastasis. Failure patterns and survival outcomes were analyzed. Pelvic failure was observed in twenty-five patients; twenty-one patients in group S (34%), and four patients in group S+R (15%) (p = 0.066). The two-year pelvic failure-free survival rates (PFFS) of group S and group S+R were 64.8% and 80.8% (p = 0.028), respectively, and the two-year overall survival rates (OS) were 49.1% and 70.4% (p = 0.116), respectively. In a subgroup analysis of fifty-six patients who received local treatment for liver metastasis, the two-year PFFS were 64.9% and 82.9% (p = 0.05), respectively; the two-year OS were 74.1% and 80.0% (p = 0.616) in group S (n = 36) and group S+R (n = 20), respectively. Adjuvant pelvic RT significantly reduced the pelvic failure rate but its influence on overall survival was unclear. Rectal cancer patients with synchronous liver metastasis may benefit from adjuvant pelvic RT through an increased pelvic control rate and improved quality of life.
