Significance of Glisson's capsule invasion in patients with colorectal liver metastases undergoing resection. Am J Surg 2019; 218:887-893. [PMID: 30712864 DOI: 10.1016/j.amjsurg.2019.01.023] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2018] [Revised: 01/17/2019] [Accepted: 01/22/2019] [Indexed: 12/21/2022]
Abstract
BACKGROUND Significance of Glisson's capsule invasion in colorectal liver metastases (CLM) patients undergoing resection has been little investigated. METHODS CLM patients (244) with curative resection (2011-2016) were divided into two groups: patients with (Group 1; n = 49 [20%]) and without (Group 2; n = 195 [80%]) histologically-proven Glisson invasion. Eight (16%) Group 1 patients were identified by pre- or intra-operative findings. We compared characteristics between Groups 1 and 2 and determined independent prognosticators. RESULTS Group 1 was more commonly associated with right-sided primary, CLM>5 cm, and R1 resections. Independent factors on reduced OS in entire cohort were pre-surgical chemotherapy [hazard ratio (HR): 2.68, P = 0.001], CLM>5 cm (HR: 4.39, P = 0.002), moderate or poor differentiation (HR: 2.38, P = 0.004), and R1 resection (HR: 1.92, P = 0.035). CONCLUSIONS CLM Glisson invasion was significantly associated with R1 resection. Advancements in determining Glisson invasion pre- or intra-operatively might produce benefits for CLM patients undergoing resection by reducing R1 resection.

Abstract
The determinants of prognosis in patients with colorectal liver metastases (CLM) have been traditionally searched among the tumoral factors, either of the primary colorectal tumor or of the CLM. While many different scoring systems have been developed based on those clinic-pathological factors with disparate results, there has been the introduction of genetic biological markers that added a theranostic perspective. More recently, other important elements, such as those factors related to the host immune system, have been proposed as determinants of prognosis of CLM patients. In the present work, we review the current prognostic factors of CLM patients as well as the burgeoning shifting paradigm of prognostication that relies on the host immune system.

Abstract
Although intrabiliary metastasis of carcinoma in the liver is unusual, intraductal and/or intraepithelial spread of cancer cells along intrahepatic bile ducts is now well recognized as hepatic metastasis. However, several clinical and laboratory findings, including images, lead us to differentially diagnose from primary intrahepatic cholangiocarcinoma. We report here on a case of colonic adenocarcinoma that metastasized to the liver with spread along with the intrahepatic bile duct of S5/6 area. The patient was a 51-year-old man and clinically diagnosed liver metastasis of sigmoid colon cancer (tub2, pMP, ly1, v0, n0), which was diagnosed and treated by sigmoidectomy 7 years ago. The right hepatic lobectomy was performed in March 2016 and histopathological examination revealed that moderately differentiated adenocarcinoma proliferated along the epithelium of intrahepatic bile ducts. Immunohistochemistry (IHC) showed that cancer cells in the intrahepatic bile ducts were positive for CK20, CDX2, CK17 and CK19, but negative for CK7, MUC-5AC, MUC-2 and CA19-9. The findings were almost the same as those of the sigmoid colon cancer removed in July 2009. We finally diagnosed the liver tumor as intrahepatic biliary metastasis of sigmoid colon cancer. Patients with liver metastasis of cancer are hard to be detected biliary invasion and spread on diagnostic image examination. Knowledge of distinctive morphological and IHC features can help to accurately diagnose this rare intrahepatic biliary metastasis of colonic cancer in routine pathological diagnostic procedures.

Abstract
Liver metastases from colorectal carcinoma commonly form nodular lesions in the liver parenchyma. We report a case of liver metastasis from rectal adenocarcinoma that extended predominantly into the bile duct. A 62-year-old Japanese man underwent low anterior resection for rectal adenocarcinoma 9 years ago. Approximately 3 years later, he underwent radiofrequency ablation therapy for a metastatic liver tumor. Nine years after surgery, a tumor in liver segment III exhibiting intrabiliary extension was discovered; it was unclear if this was a metastatic liver tumor or intrahepatic cholangiocarcinoma. Accordingly, we performed a left hepatectomy with lymph node dissection. The tumor was negative for cytokeratins 7 and 20, and was histologically similar to the primary rectal adenocarcinoma; it was diagnosed as rectal carcinoma metastasis. The patient has survived for 3 years after the hepatic surgery, for 9 years after radiofrequency ablation therapy, and for 12 years after the primary surgery. This case shows that liver metastasis from colorectal carcinoma can present as a predominantly intrabiliary growth that mimics intrahepatic cholangiocarcinoma on imaging. Moreover, our case provides evidence for the superiority of anatomical hepatectomy over partial hepatectomy for metastatic liver tumors with intrabiliary growth arising from rectal adenocarcinomas.

Abstract
BACKGROUND Prophylactic impact of major hepatectomy (MH) on liver recurrence has yet to be clarified in patients with advanced colorectal liver metastases (CLMs). METHODS In our institute, parenchymal-sparing hepatectomy (PSH) is a standard procedure for CLMs consistently throughout initial and repeat resection, and MH is selected only in cases in which CLMs are close to major Glisson's pedicles. We reviewed 145 patients who underwent curative hepatectomy for advanced CLMs (≥4 nodules and ≤50 mm in size) from 1999 to 2012. Surgical outcomes and survival were compared between patients who underwent PSH and MH. RESULTS PSH was performed in 113 patients (77.9 %) and MH in 32 (22.1 %) patients with advanced CLMs. Tumor characteristics and short-term outcomes did not differ between the 2 groups. Incidence of positive tumor margin (8.8 % in PSH vs 9.4 % in MH; p = .927) and rates of liver-only recurrence (43.4 % in PSH and 50.0 % in MH; p = .505) did not differ. No significant differences were found in 5-year overall survival (37.0 % in PSH vs 29.4 % in MH, p = .473), recurrence-free survival (7.6 vs 6.8 %, p = .597), and liver recurrence-free survival (21.0 vs 21.3 %, p = .691). A total of 65 patients had liver-only recurrence, for which repeat hepatectomy was performed in 81.5 % (53 of 65) following our parenchymal-sparing approach. CONCLUSIONS In patients with advanced CLM, PSH does not increase positive surgical margin or liver recurrence in comparison with MH. A parenchymal-sparing approach offers a high rate of repeat resection for liver recurrence (salvageability).

Abstract
BACKGROUND The optimal surgical strategy for the treatment of synchronous resectable gastric cancer liver metastases remains controversial. The aims of this study were to analyze the outcome and overall survival of patients presenting with gastric cancer and liver metastases treated by simultaneous resection. MATERIALS AND METHODS Between January 1990 and June 2009, 35 patients diagnosed with synchronous hepatic metastases from gastric carcinoma received simultaneous resection of both primary gastric cancer and synchronous hepatic metastases. The clinicopathologic features and the surgical results of the 35 patients were retrospectively analyzed. RESULTS The 5-year overall survival rate after surgery was 14.3%. Five patients survived for more than 5 years after surgery. No mortality has occurred within 30 days after resection, although two patients (5.7%) developed complications during the peri-operative course. Univariate analysis revealed that patients with the presence of lymphovascular invasion of the primary tumor, bilateral liver metastasis and multiple liver metastases suffered poor survival. Lymphovascular invasion by the primary lesion and multiple liver metastases were significant prognostic factors that influenced survival in the multivariate analysis (p=0.02, p=0.001, respectively). CONCLUSIONS The presence of lymphovascular invasion of the primary tumor and multiple liver metastases are significant prognostic determinants of survival. Gastric cancer patients without lymphovascular invasion and with a solitary synchronous liver metastasis may be good candidates for hepatic resection. Simultaneous resection of both primary gastric cancer and synchronous hepatic metastases may effectively prolong survival in strictly selected patients.

Abstract
Backgrounds/Aims Hepatic resection has only guaranteed long-term survival in patients with colorectal liver metastasis (CRLM) even in the era of effective chemotherapy. The definite role of neoadjuvant chemotherapy (NCT) is to improve outcomes of unresectable CRLMs, but it its role has not been defined for initially resectable CRLMs (IR-CRLMs). Methods We reviewed the medical records of 226 patients, who had been diagnosed and treated for IR-CRLM between 2003 and 2008; the patients had the following pathologies: 10% had more than 4 nodules, 11% had tumors larger than 5 cm, and 61% had synchronous CRMLs. Among these patients, 20 patients (Group Y) were treated with NCT, and 206 (Group N) did not receive NCT according to their physician's preference. The median follow-up time was 34.1 months. Results The initial surgical plans were changed after NCT to further resection in 20% and to limited resection in 10% of 20 patients. Complication rates of Groups Y (30%) were indifferent from Group N (23%) (p=0.233), but intraoperative transfusions were more frequent in Group N (15%) than in Group Y (5%) (p=0.006). There was one case of hospital mortality (0.44%). Disease-free survival rates in Groups Y and N were 23% and 39%, respectively, and patient survival rates were 42% and 66% (p>0.05). By multivariate analysis, old age (≥60 years), differentiation of primary tumor (poorly/mucinous), resection margin involvement, and no adjuvant chemotherapy were associated with poor patient survival; the number of CRLMs (≥4) was associated with poor disease-free survival. Conclusions NCT had neither a positive impact nor a negative impact on survival, even with intraoperative transfusion, as observed on operative outcomes for patients with IR-CRLM. Further study is required to elucidate the role of NCT for treatment of patient with IR-CRLMs.

Abstract
The diagnosis and management of CRLM is complex and requires a multidisciplinary team approach for optimal outcomes. Over the past several decades, the 5-year survival following resection of CRLM has increased and the criteria for resection have broadened substantially. Even patients with multiple, bilateral CRLM, previously thought unresectable, may now be candidates for resection. Two-stage hepatectomy, repeat curative-intent hepatectomy, and even selected resection of extrahepatic metastases have further increased the number of patients who may be treated with curative intent. Multiple liver-directed therapies exist to treat unresectable, incurable patients with adequate survival benefit and morbidity rates.

Abstract
Morphologically, liver metastases from colorectal carcinoma usually form as nodular tumor masses, whereas intraductal papillary growth in the bile duct is rare. A 65-year-old man underwent right hemicolectomy for advanced colon carcinoma, and histology of the primary carcinoma confirmed moderately differentiated adenocarcinoma with subserosal invasion, no vascular infiltration, and no lymph node metastasis. A liver tumor was found in the right paramedian Glisson pedicle and intraductal growth of cholangiocarcinoma was seen on imaging. We performed right hepatectomy and macroscopically, the resected specimen contained a growth in the bile duct lumen similar to cholangiocarcinoma. Histological examination revealed intraductal papillary proliferation of well-differentiated adenocarcinoma without vascular infiltration or lymph node metastasis in the hepatic hilum. Immunohistochemical staining revealed that the tumor cells were negative for cytokeratin-7 and positive for cytokeratin-20. Based on these findings, liver metastasis from colon carcinoma was diagnosed. Liver metastasis from colorectal carcinoma rarely arises as intraductal papillary growth in the bile duct, but the possibility of liver metastases with unusual morphology must be borne in mind for patients with a history of carcinoma in the digestive tract.

Abstract
Backround Micrometastases of colorectal liver metastases are present in up to 50% of lesions. In this study we sought to determine the threshold dose for local control of occult micrometastases in patients undergoing CT (computed tomography)-guided brachytherapy of colorectal liver metastases. Materials and methods Nineteen patients demonstrated 34 local tumor recurrences originating from micrometastases after CT-guided brachytherapy of 27 colorectal liver metastases. We considered a local tumor recurrence as originating from a micrometastasis if tumor regrowth occurred adjacent to a formerly irradiated lesion and the distance of the 3D isocenter of the new lesion was ≤ 23.5 mm from the previous tumor margin. Follow-up MRI was fused with the planning-CT and dosimetry data. Two reviewers independently indicated the dose exposure at the isocenter of the micrometastases. Statistical analysis included an analysis of variance (ANOVA) using backward selection. 95% tolerance intervals with coverage of 87.5 and 75% of the data of the normal distribution were calculated. Results The median distance of the micrometastases to the margin of the originating colorectal metastases was 8.75 mm (1-21 mm). Dose exposure at the isocenter was 12.25 Gy (7-19.8) in median. We stratified according to the distance from the isocenter to the initial tumor margin: ≤ 9 mm, > 9-15 mm and > 15 mm. The median dose in the according isocenters was 13.18, 11.6 and 11.85 Gy. The threshold dose failing to prevent micrometastasis growth was sigificantly higher in a subgroup of lesions with ≤ 9 mm distance as compared to > 15 mm (13.18 vs 11.85 Gy). Adjuvant chemotherapy correlated with greater distance of micrometastasis growth to the tumor but not with the threshold dose. Conclusion To prevent loss of local tumor control by continuous growth of micrometastases a threshold dose of 15,4 Gy (single fraction) should be delivered at a distance of 21 mm to the gross tumor margin.

Abstract
INTRODUCTION Over the past decade, the emergence of surgical adjuncts such as portal vein embolization, two-stage hepatectomy, and ablative therapies not only decreases mortality and morbidity after an extended hepatectomy but also broadens the indication for surgical treatment of liver metastasis from colorectal cancer. Combination chemotherapeutic regimens, namely 5-fluorouracil/folinic acid with irinotecan or oxaliplatin, and targeted monochromal antibodies can downsize the tumor burden to the extent that formerly unresectable metastases can sometimes be excised. DISCUSSION The 5-year survival rate following liver resection ranges between 25% and 58%. During the 5-fluorouracil/folinic acid with oxaliplatin and 5-fluorouracil/folinic acid with irinotecan treatment period, the patients who were deemed to be resectable should be considered as surgical candidates regardless of the associated adverse predictive factors. The emergence of epidermal growth factor receptor antibody agents, which act effectively in patients with Kras wild-type tumor, fosters treatment individualization. CONCLUSION The efficacy of the perioperative chemotherapy on survival benefit for resectable liver metastases has not been justified. However, the timing and indication of surgical treatment paradigm in colorectal liver metastasis, including for synchronous disease and extrahepatic disease, are dramatically changing with the development of chemotherapeutic agents.

Abstract
PURPOSE For patients with colorectal liver metastases (CLM), regional lymph node (RLN) involvement is one of the worst prognostic factors. The objective of this study was to evaluate the ability of a multidisciplinary approach, including preoperative chemotherapy and hepatectomy, to improve patient outcomes. PATIENTS AND METHODS Outcomes for a consecutively treated group of patients with CLM and simultaneous RLN involvement were compared with a cohort of patients without RLN involvement. Univariate and multivariate analysis of clinical variables was used to identify prognostic factors in this high-risk group. Results Of the 763 patients who underwent resection at our institution for CLM between 1992 and 2006, 47 patients (6%) were treated with hepatectomy and simultaneous lymphadenectomy. All patients had received preoperative chemotherapy. Five-year overall survival (OS) for patients with and without RLN involvement were 18% and 53%, respectively (P < .001). Five-year disease-free survival rates were 11% and 23%, respectively (P = .004). When diagnosed preoperatively, RLN involvement had an increased 5-year OS compared with intraoperative detection, although the difference was not significant (35% v 10%; P = .18). Location of metastatic RLN strongly influenced survival, with observed 5-year OS of 25% for pedicular, 0% for celiac, and 0% for para-aortic RLN (P = .001). At multivariate analysis, celiac RLN involvement and age >or= 40 years were identified as independent poor prognostic factors. CONCLUSION Combined liver resection and pedicular lymphadenectomy is justified when RLN metastases respond to or are stabilized by preoperative chemotherapy, particularly in young patients. In contrast, this approach does not benefit patients with celiac and/or para-aortic RLN involvement, even when patients' disease is responding to preoperative chemotherapy.

Abstract
BACKGROUND Non-anatomical liver resections have become more common in the management of colorectal liver metastases. This study examined survival and patterns of recurrence following surgery for colorectal liver metastases. METHODS Data were collected prospectively on all patients who had hepatic surgery for colorectal liver metastases at St James' University Hospital, Leeds between 1993 and May 2003, and analysed with respect to type of resection. RESULTS A total of 96 patients underwent non-anatomical liver resection, 280 patients had an anatomical resection, and 108 patients had a combined procedure. There was no significant difference in overall survival between the anatomical and non-anatomical groups (hazard ratio 1.14 (95 per cent confidence interval 0.60 to 2.17); P = 0.691). Intrahepatic recurrence was significantly less common in the anatomical group, whereas morbidity and mortality rates were lower in the non-anatomical group. On multivariable analysis, multiple metastases and poorer primary T stage predicted poorer overall survival and a positive resection margin predicted poorer disease-free survival. CONCLUSION Non-anatomical resection can be performed with lower rates of surgical morbidity and mortality than anatomical resection, and does not disadvantage the patient in terms of overall survival.

Abstract
Colorectal cancer is the fourth most common type of cancer in the West and the second leading cause of cancer-related deaths in the United States. Approximately 35 to 55% of patients with colorectal cancer develop hepatic metastases during the course of their disease. Surgical resection of colorectal liver metastases represents the only chance at potential cure, and long-term survival can be achieved in 35 to 58% of patients after resection. The goal of hepatic resection should be to resect all metastases with negative histologic margins while preserving sufficient functional hepatic parenchyma. In patients with extensive metastatic disease who would otherwise be unresectable, ablative approaches can be used instead of or combined with hepatic resection. The use of portal vein embolization and preoperative chemotherapy may also expand the population of patients who are candidates for surgical treatment. Despite these advances, many patients still experience a recurrence after hepatic resection. More active systemic chemotherapy agents are now available and are being increasingly employed as adjuvant therapy either before or after surgery. Modern treatment of colorectal liver metastasis requires a multidisciplinary approach in an effort to increase the number of patients who may benefit from surgical treatment of colorectal cancer liver metastasis.

Abstract
BACKGROUND In cases of synchronous colorectal hepatic metastases, the primary colorectal cancer strongly influences on the metastases. Our treatment policy has been to conduct hepatic resection for the metastases at an interval of 3 months after colorectal resection. We examined the appropriateness of interval hepatic resection for synchronous hepatic metastasis. MATERIALS AND METHODS The subjects were 164 patients who underwent resection of hepatic metastasis of colorectal cancer (synchronous, 70 patients; metachronous, 94 patients). Background factors for hepatic metastasis and postoperative results were compared for synchronous and metachronous cases. RESULTS The cumulative survival rate for 164 patients at 3, 5, and 10 years postoperatively was 71.9%, 51.8%, and 36.6%, and the post-resection recurrence rate in remnant livers was 26.8%. Interval resection for synchronous hepatic metastases was conducted in 49 cases after a mean interval of 131 days. No difference was seen in postoperative outcome between synchronous and metachronous cases. CONCLUSION The outcome was similarly favorable in cases of synchronous hepatic metastasis and in cases of metachronous metastasis. Delaying resection allows accurate understanding of the number and location of hepatic metastases, and is beneficial in determining candidates for surgery and in selecting surgical procedure.

Abstract
BACKGROUND We retrospectively identified the prognostic factors in cases of synchronous liver metastases from colorectal cancer and established a clinical strategy at our institution. METHODS One hundred eight patients with hepatic metastases from colorectal cancer underwent a first radical hepatic resection. Of these, 67 were diagnosed with hepatic synchronous metastases from colorectal primaries (S group) and 41 were diagnosed with metachronous metastases (M group). Hepatic lesions were diagnosed concurrently with the primary lesions in 45 of the 67 patients in the S group. Of these 45 patients, 37 underwent synchronous hepatectomy (SH group) and 8 underwent metachronous hepatectomy (MH group). RESULTS The overall 3-, 5- and 10-year survival rates were 51.4%, 41.6%, and 30.9%, respectively. There were no significant differences between the S and M groups in overall survival. Univariate analysis of the S group revealed significant differences in survival based on tumor factor, pathological lymph node metastases of the primary tumor, and the tumor-free margin. There were no significant differences between the SH and MH groups in overall survival. CONCLUSIONS Patients with synchronous liver metastases from colorectal cancer should undergo radical resection of the primary lesion and simultaneous hepatectomy with an adequate tumor-free margin as a standard surgical course.

Abstract
BACKGROUND Recent advances have extended indications for hepatectomy to include multiple bilobar colorectal liver metastases (CLM). Staging systems based on the biological malignancy of primary and metastatic tumors provide appropriate indications for hepatectomy in CLM. However, suitability for resection in patients with complex and extensive hepatic metastases is controversial. METHODS A medline search was performed to identify papers reporting the resection for CLM. Techniques, indication, and results were reviewed. RESULTS If the anticipated remnant liver volume is small (25-40% of total), suggesting a high risk of postoperative liver failure, portal vein embolization (PVE) is recommended prior to hepatectomy. However, curative resections are not always possible. Specifically in synchronous multiple bilobar CLM, two-stage hepatectomy, comprising bilateral hepatectomy and primary resection with or without PVE, can prevent growth of ipsilateral metastatic nodules in the remnant liver and reduce surgical risk. Several local ablation techniques can complement surgery if hepatic resection alone increases the risk of postoperative liver failure or is not curative. Chemotherapy combined with targeted treatment can suppress recurrence and extend indications for hepatectomy by reducing the size and number of primary irresectable tumors. CONCLUSION PVE or staged procedure combining with local ablation or neoadjuvant, downstaging or adjuvant therapies extends indications for hepatectomy to include multiple bilobar CLM. The 5-year survival rate for multiple bilobar CLM treated with alternating hepatectomy and chemotherapy is comparable to the values reported for single and hemilateral CLM.

Abstract
The present study evaluated the feasibility of combined therapy employing repeated hepatic arterial infusion chemotherapy (HAIC) via a port-catheter system and radiofrequency (RF) ablation for unresectable metastatic liver cancer from the colo-rectum. RF ablation was performed for six patients with liver malignancies that had been well controlled and had decreased in number and size with repeated HAIC. After RF ablation subsequent to repeated HAIC, all six patients had stable disease or complete or partial remission as documented by follow-up contrast-enhanced computed tomographic (CT) imaging. Fluorodeoxyglucose positron emission tomography (18F) showed complete response in all ablated lesions. In conclusion, RF ablation after a course of HAIC achieved complete necrosis in residual lesions after HAIC therapy.

Abstract
Abstract
Background
In some patients undergoing right hepatic trisectionectomy for metastases, extension of the resection beyond the falciform ligament is necessary to achieve tumour clearance. The aim of the present study was to assess the early and long-term outcomes and hepatic function in patients who underwent extensive liver resection beyond right trisectionectomy.
Methods
Thirty-eight patients who had extension of a right trisectionectomy, either in contiguity (IC) or in a non-anatomical (NA) fashion, for liver metastases were included in the study. In-hospital mortality, hepatic function and other morbidity were recorded. Survival outcomes were analysed for the subgroup of patients with colorectal liver metastases. The clinical risk score described by the Memorial Sloan–Kettering Cancer Center was applied to all patients with colorectal liver metastases.
Results
Sixteen patients had IC resection, 15 NA resection, and seven had both IC and NA procedures. There was one in-hospital death. Hepatic dysfunction was seen in 25 patients and two developed liver failure. Disease-free actuarial 3-year survival was 42 per cent for patients with colorectal liver metastases. Survival was significantly better in patients with a clinical risk score of 3 or less.
Conclusion
Extension of right trisectionectomy for liver metastases was associated with a low risk of death and hepatic failure.

Abstract
BACKGROUND Attempts at identifying prognostic factors after hepatectomy in patients with colorectal liver metastases have not achieved consensus. We investigated prognostic factors ascertainable before hepatectomy for colorectal metastasis. METHOD Clinicopathological data for 149 consecutive patients with colorectal cancer who underwent curative resection of primary lesions and metastatic liver disease at one institution were subjected to multivariate analysis concerning metastatic status and the primary lesion. RESULTS Poorly differentiated adenocarcinoma or mucinous carcinoma as the primary tumor (Poor/muc; P=0.026), marked vascular invasion by the primary tumor (V; P=0.002), bi-lobar liver metastases ( P=0.048), and short doubling time (DT) of the liver tumor ( P=0.028) were characteristics assessable before hepatectomy that independently indicated poorer survival. A four-stage classification based on these factors was related to overall ( P<0.01) and disease-free ( P<0.01) survival rates. No pattern of recurrence site was evident in stage I (patients with no risk factor). Recurrence was usually extrahepatic in stage IV (patients with Poor/muc) but favored the remnant liver in stage II (patients with bi-lobar metastases or short DT) or III (patients with V; P=0.037). Stage III showed more multiple and early hepatic recurrences than stage II, and repeat hepatectomy was less frequent ( P<0.05). CONCLUSION Pre-hepatectomy prognostic staging should help to guide treatment of liver metastases.

Abstract
Although liver resection offers the only realistic chance of cure for patients with liver metastases from colorectal cancer, no consensus exists as to the procedure of choice for managing these tumors. Data from 193 patients who underwent hepatectomy for liver metastases from colorectal cancer and 26 of 193 patients who underwent repeat hepatectomy for recurrent metastases were collected. The suitability of resection was evaluated retrospectively based on known risk factors for recurrence and patterns of recurrence. On multivariate analysis, a positive surgical margin (SM+) was the only risk factor for recurrence after the initial resection (p < 0.01). SM+ (p < 0.01) and nonanatomic resection (p < 0.05) that was less than a sectionectomy (p < 0.05) were risk factors for recurrence after repeat hepatectomy. Multiple tumors (four or more) was the most common pattern of recurrence after initial hepatectomy, and recurrence close to the line of resection was most common after repeat hepatectomy. Based on tumor doubling times, recurrence after initial hepatectomy seemed to originate from the primary colorectal lesion, whereas recurrence after repeat hepatectomy was derived from a hepatic metastasis. Retrospective analysis suggests that hepatectomy with clear surgical margins is more important than anatomic resection for initial hepatectomy, and at least sectionectomy is necessary for repeat hepatectomy.

Abstract
We determined the relative value of the metastatic colorectal cancer doubling time as a predictor of recurrence and survival after hepatectomy in comparison with other established predictors. Consecutive patients who underwent hepatic resection ( n = 144) for colorectal cancer liver metastases were studied retrospectively to identify factors that influence overall survival and recurrence in the remnant liver. Overall 5-year survival and nonrecurrence rates were 49.8% and 50.8%, respectively. By multivariate analysis, large liver tumors ( p = 0.038), p53 expression by the liver tumor (p = 0.011), and a short liver metastasis doubling time (< or = 45 days, p = 0.013) negatively affected survival; doubling times > 45 days (adjusted relative risk 0.06; p < 0.001) positively influenced disease-free survival. In patients with remnant liver recurrence, a short doubling time was associated with short disease-free intervals (7.3 +/- 6.2 months), multiple metastases (63.6%), and fewer attempts at repeat hepatectomy (22.7%). The doubling time determines tumor size and reflects the patient's immune and nutritional status. A short doubling time is the most reliable risk factor for multiple metastases, early recurrence, and poor prognosis. Further studies with a larger number of patients are needed to confirm this conclusion.

Abstract
BACKGROUND Although routine follow-up to detect asymptomatic recurrence after surgery for gastric cancer is recommended, the effect of such reassessment on survival has not been evaluated. METHODS Clinical records of patients developing recurrent disease after potentially curative resection between 1985 and 1996 were retrieved. Among these patients, 197 were in our follow-up program. We analyzed survival in these patients according to the presence or absence of cancer-related symptoms when recurrent disease was diagnosed. RESULTS Of all patients with recurrent disease, 50% were diagnosed within 1 year and 75% within 2 years of surgery. Asymptomatic recurrence, detected in 88 patients (45%), frequently represented distant metastasis. Although early detection significantly improved survival after detection of recurrent disease, disease-free survival for this subset was shorter. Thus, no significant difference in overall survival was observed. CONCLUSIONS Early detection of asymptomatic gastric cancer recurrence did not improve overall survival of patients with recurrence after curative resection. Until development of more effective treatment for this disease, close follow-up may offer no survival benefit.

Abstract
BACKGROUND AND OBJECTIVES Tumor infiltrating lymphocytes (TILs) have been recognized as a tumor-host reaction in various primary neoplasms. Although several studies reported TILs surrounding metastatic liver tumors, to the authors' knowledge few evaluations of the clinical significance of such features in patients with colorectal liver metastases have been carried out. METHODS Forty-one patients who underwent initial hepatic resection for liver metastases from colorectal cancer were studied. Lymphocytic infiltration surrounding metastatic liver tumor was graded as weak or dense according to the mean number of TILs from 10 high-power microscopic fields (< or =50 or >50/HPF). RESULTS Dense lymphocytic infiltration between the metastatic tumor and hepatic parenchyma was seen in 18 of 41 patients (44%). Histologically, tumor invasion of the portal vein was rare in patients with dense TILs (12%) compared with patients with weak TILs (36%). Patients with dense TILs survived longer than patients with weak TILs after hepatic resection (P = 0.013). Multivariate analysis using the Cox proportional hazard model identified this pathological variable as a significant independent prognostic factor after hepatic resection. CONCLUSIONS The extent of lymphocytic infiltration between the metastatic nodule and hepatic parenchyma may reflect host defensive activity in the liver and is closely related to prognosis in patients who underwent hepatic resection for liver metastases from colorectal cancer.

Abstract
Hepatic resections for metastatic colorectal cancer have dramatically increased, and there is clear evidence of the effectiveness of this type of surgery. Controversy, however, persists regarding appropriate patient selection, extent and timing of liver resection, and adjuvant or alternative therapeutic options. This article reviews the authors' experience with more than 600 hepatic resections and the relevant literature is discussed. The results underscore the importance of macroscopically and histologically complete tumor clearance, a so-called "R0 resection."

Abstract
We have previously reported the frequent occurrence of bile duct invasion by liver metastases from colorectal cancer. We found that patients with macroscopic intrabiliary cancer growth survive longer after hepatectomy than those without this feature. In the present study, we analyzed the clinicopathological features of primary colorectal cancer showing macroscopic intrabiliary extension of liver metastases. We reviewed 217 patients who underwent initial hepatic resection for colorectal liver metastasis between 1992 and 1998, and analyzed the corresponding primary colorectal cancers clinicopathologically. Microscopic bile duct invasion was found in 89 of 217 cases (40.6%) and, of these cases, 23 (10.6%) had macroscopic intrabiliary extension. Histological sections of the corresponding primary colorectal cancer were available in eight (group A) of these 23 cases. These were compared with 20 cases, selected randomly, of colorectal cancer that did not show bile duct invasion and were diagnosed as liver metastases. These patients underwent hepatectomy during the same period as group A and were used as a control (group B). The histology of the primary tumors revealed well-differentiated adenocarcinoma in 100% of group A and in 25% of group B. The average maximum diameter of the primary tumor was 5.32 cm in group A and 3.61 cm in group B. Venous invasion was detected in 25% of group A and in 90% of group B (P < 0.01), while the incidences of lymphatic vessel invasion and lymph node metastases were similar between the groups. These data suggest that macroscopic intrabiliary extension could be a good indicator of a unique subgroup of colorectal cancers showing less aggressive features even though they develop liver metastases. Careful histological evaluation is important even for metastatic tumors.

Abstract
BACKGROUND Intrahepatic spread from liver metastases of colorectal carcinoma has been well described; however, its prognostic value after hepatectomy is controversial. To clearly determine factors predicting survival after hepatectomy in such patients, the authors evaluated 14 clinicopathologic factors of liver metastasis from colorectal carcinoma with special reference to intrahepatic lymphatic invasion. METHODS The authors retrospectively analyzed data obtained from 67 consecutive patients who underwent hepatectomy for liver metastasis from colorectal carcinoma. Intrahepatic spread was classified into discreet categories that were evaluated separately: invasion to the portal vein, hepatic vein, bile duct, and lymphatic or perineural space. Overall survival and disease free survival periods were examined as functions of clinicopathologic determinants by univariate and multivariate analyses. RESULTS Intrahepatic spread was found in a total of 28 (43.1%) of the 65 evaluable cases. Portal vein invasion was found in 15 (23.1%) of these cases, hepatic vein invasion in 3 (4.6%), bile duct invasion in 10 (15.4%), and intrahepatic lymphatic invasion in 10 (15.4%). Five year overall and disease free survival rates after hepatectomy were 33.4% and 28.5%, respectively. A short interval (< 12 months) from treatment of primary colorectal carcinoma to liver metastasis and the presence of intrahepatic lymphatic invasion significantly and adversely affected the overall and disease free survival rates. CONCLUSIONS Intrahepatic lymphatic invasion was shown statistically to be an independent predictor of recurrence and death after hepatectomy in patients with liver metastases from primary colorectal carcinoma.

Abstract
In 30-50% of patients the liver is a preferred site of distant disease for many malignant tumours. Due to the high incidence, most of the available data relate to metastases arising from colorectal primaries. Surgical resection is at present the only treatment offering potential cure. The achievable 5-year survival rate is 30%. However, only 10-15% of patients with colorectal liver metastases can undergo potentially curative liver resection. Therefore, accurate staging is an important prerequisite in selecting patients who would benefit from surgery. Recurrence of hepatic metastases after potentially curative resection occurs in up to 60% of the cases. Results demonstrate that re-resection of liver metastases can provide long-term survival rates in a carefully selected group of patients without extrahepatic disease. Because of the high rate of recurrences following an apparently curative resection several authors investigated the use of adjuvant chemotherapy (systemic, intraportal, and hepatic arterial infusion). Until recently none had shown effectiveness. Pre-operative chemotherapy seems to be a promising approach in patients with liver metastases initially considered unsuitable for radical surgery. Recently, neoadjuvant chemotherapy has been proposed as an alternative approach to conventional surgery as initial management with the aim of improving the results in resectable liver metastases. Interventional strategies (ethanol injection, cryosurgery, laser-induced thermotherapy, radio-frequency ablation) and combined modalities (surgical/interventional) are additive methods which may help to improve treatment results in the future.

Abstract
OBJECTIVE To assess the surgical results and clinicopathologic features of hepatic metastases from gastric adenocarcinoma to identify patients with a better probability of survival. SUMMARY BACKGROUND DATA Many studies have reported the benefit of hepatic resection for metastatic tumors from colorectal cancer. However, indications for a surgical approach for gastric adenocarcinoma involving the liver have not been clearly defined. METHODS Ninety (11%) of 807 patients with primary gastric cancer were diagnosed with synchronous (n = 78) or metachronous (n = 12) hepatic metastases. Of these, 19 underwent 20 resections intended to cure the metastatic lesion in the liver. The clinicopathologic features of the hepatic metastases in, and the surgical results for, the 19 patients were analyzed. RESULTS The actuarial 1-year, 3-year, and 5-year survival rates after hepatic resection were, respectively, 77%, 34%, and 34%, and three patients survived for more than 5 years after surgery. Solitary and metachronous metastases were significant determinants for a favorable prognosis after hepatic resection. Pathologically, a fibrous pseudocapsule between the tumor and surrounding hepatic parenchyma was found in 13 of the 19 patients (68%). The presence of a peritumoral fibrous pseudocapsule and a well-differentiated histologic type of metastatic nodule were significant prognostic factors. Factors associated with the primary lesion were not significant prognostic determinants in patients who underwent curative resection of the primary cancer. CONCLUSIONS Solitary and metachronous metastases from gastric cancer should be treated by a surgical approach and confer a better prognosis. A new prognostic factor, the presence of a pseudocapsule, may be helpful in defining indications for postoperative adjuvant treatment.

Abstract
PURPOSE The gross appearance of colorectal carcinoma liver metastases reflects the biologic behavior of the tumor, yielding prognostic information. The aims of this retrospective study were to determine whether preoperative computed tomographic features of colorectal carcinoma liver metastases reflect the gross appearance of resected specimens and whether these computed tomographic hepatic features predict survival after hepatectomy. METHODS Eighty-five patients underwent curative partial hepatectomy for colorectal carcinoma liver metastases. Preoperative computed tomographic features of the largest hepatic deposit were classified by the contour of advancing margin of the tumor into two types: lobular tumors with indentations with an acute angle and nonlobular tumors without such indentations. The correlation between computed tomographic features and 18 other clinicopathologic factors was examined. RESULTS The overall five-year survival rate was 34.1 percent. Of 85 hepatic tumors examined, 49 were lobular and 36 were nonlobular. Computed tomographic features correlated significantly with gross appearance (P = 0.007). Univariate analysis revealed that computed tomographic features (P < 0.0001), gross appearance (P = 0.0063), size of the largest hepatic deposit (P = 0.0075), age (P = 0.0140), and satellite lesions (P = 0.0443) were significant prognosticators. The five-year survival rates in patients with lobular and nonlobular tumors were 10.4 and 66.1 percent, respectively. By multivariate analysis, computed tomographic features (P < 0.0001) and size of the largest hepatic deposit (P = 0.0419) were independently significant. CONCLUSIONS Computed tomographic features of colorectal carcinoma liver metastases correlate with their gross appearance. The computed tomographic characterization of liver metastases is the most important independent prognostic factor in patients undergoing curative hepatectomy.

Abstract
The present study was designed to provide a systemic analysis of prognosis in 62 patients who underwent hepatic resection for colorectal liver metastasis. The analyzed factors included microvessel counts stained by CD34 and expression of two adhesion molecules, E-cadherin and CD44 variant exon 6-(v6) in these tumors. No significant factors related to recurrence were identified and only negative expression of CD44v6 tended to correlate with recurrence (P = 0.075). A short disease-free period to recurrence was noted in patients with high CEA levels (>10 ng/ml) and H2/3 classification. A short surgical margin, H2/3 classification, high microvessel counts (>60/field, x200), and negative expression of CD44v6 and E-cadherin tended to be associated with poor prognosis. A high microvessel count was the most significant prognostic factor by multivariate Cox proportional hazards regression model. Hepatic resection without tumor exposure and a careful follow-up in cases identified with poor prognostic factors are necessary.

Abstract
OBJECTIVE To correlate the microscopic finding of entrapped liver cells in hepatic metastases from colorectal cancer with outcome after hepatectomy. SUMMARY BACKGROUND DATA Reliable histopathologic prognostic factors in resected liver metastases from colorectal cancer have not been identified. METHODS Seventy-one patients undergoing radical hepatectomy for liver metastases were assigned to rare (n = 36) or frequent (n = 35) groups according to the microscopically observed frequency of hepatocyte entrapment in the tumor. RESULTS Five-year survival rates after hepatectomy were 44. 4% for the rare group and 27.2% for the frequent group. Multivariate analysis using the Cox proportional hazards model by a stepwise method identified this morphologic variable as a significant independent prognostic factor. CONCLUSIONS The finding of entrapped liver cells in metastases from colorectal cancer reflects the biologic activity of the tumor and may be a useful prognostic indicator.

Abstract
BACKGROUND Liver resection for colorectal metastases is the only known treatment associated with long-term survival; extrahepatic disease is usually considered a contraindication to such treatment. However, some surgeons do not regard spread to the hepatic lymph nodes as a contraindication provided that these nodes can be excised adequately. A systematic review of the literature was undertaken to address this issue. METHODS An electronic search using Medline, Cancerlit and Embase databases was performed for studies reporting liver resection for colorectal metastases from 1964 to 1999. Data were extracted from papers reporting outcome for patients with positive hepatic nodes and analysed according to predetermined criteria. RESULTS Fifteen studies were identified that gave survival data on 145 node-positive patients. Five patients were reported to have survived 5 years after liver resection; one was disease free, two had recurrent disease and the disease status was not described in the remaining two. Five studies containing 83 patients specified a formal lymph node dissection as part of the surgical procedure and four of the five node-positive 5-year survivors were from these studies. CONCLUSION There are few 5-year survivors after liver resection, with or without lymph node dissection, for colorectal hepatic metastases involving the hepatic lymph nodes.

Abstract
OBJECTIVE To evaluate retrospectively the long-term results of an approach consisting of performing surgery in every patient in whom radical removal of all metastatic disease was technically feasible. SUMMARY BACKGROUND DATA The indications for surgical resection for liver metastases from colorectal cancer remain controversial. Several clinical risk factors have been reported to influence survival. METHODS Between March 1980 and December 1997, 235 patients underwent hepatic resection for metastatic colorectal cancer. Survival rates and disease-free survival as a function of clinical and pathologic determinants were examined retrospectively with univariate and multivariate analyses. RESULTS The overall 3-, 5-, 10-, and 15-year survival rates were 51%, 38%, 26%, and 24%, respectively. The stage of the primary tumor, lymph node metastasis, and multiple nodules were significantly associated with a poor prognosis in both univariate and multivariate analyses. Disease-free survival was significantly influenced by lymph node metastasis, a short interval between treatment of the primary and metastatic tumors, and a high preoperative level of carcinoembryonic antigen. The 10-year survival rate of patients with four or more nodules (29%) was better than that of patients with two or three nodules (16%), and similar to that of patients with a solitary lesion (32%). CONCLUSIONS Surgical resection is useful for treating liver metastases from colorectal cancer. Although multiple metastases significantly impaired the prognosis, the life expectancy of patients with four or more nodules mandates removal.

Abstract
OBJECTIVE The purpose of our study was to evaluate the use of combined helical CT during arterial portography and CT hepatic arteriography in the preoperative assessment of hepatic metastases from colorectal cancer using a unified CT and angiography system. MATERIALS AND METHODS Fifty-four patients with hepatic metastases from colorectal cancer preoperatively underwent combined CT during arterial portography and CT hepatic arteriography using the unified CT and angiography system. Three radiologists independently and retrospectively reviewed the images of CT during arterial portography alone, CT hepatic arteriography alone, and combined CT during arterial portography and CT hepatic arteriography. Image review was conducted on a segment-by-segment basis; a total of 432 hepatic segments with (n = 103) 118 metastatic tumors ranging in size from 2 to 160 mm (mean, 25.8 mm) and without (n = 329) tumor were reviewed. RESULTS Relative sensitivity of combined CT during arterial portography and CT hepatic arteriography (87%) was higher than that of CT during arterial portography alone (80%, p < 0.0005) and CT hepatic arteriography alone (83%, p < 0.005). Relative specificity of CT hepatic arteriography alone (95%, p < 0.0005) and combined CT during arterial portography and CT hepatic arteriography (96%, p < 0.0001) was higher than that of CT during arterial portography alone (91%). Diagnostic accuracy, determined by a receiver operating characteristic curve analysis, was greater with combined CT during arterial portography and CT hepatic arteriography than with CT during arterial portography alone (p < 0.05) or CT hepatic arteriography alone (p < 0.01). CONCLUSION Using a unified CT and angiography system, we found that combined CT during arterial portography and CT hepatic arteriography significantly raised the detectability of hepatic metastases from colorectal cancer.

Abstract
OBJECTIVE To analyze the survival predictors of patients undergoing hepatectomy for colorectal liver metastasis to determine useful indicators for therapy selection. SUMMARY BACKGROUND DATA Although recurrence develops in more than two thirds of patients undergoing hepatectomy for colorectal liver metastasis, preoperative characteristics that might predict such recurrence have yet to be clearly identified. METHODS Clinicopathologic data of 85 consecutive patients with colorectal cancer who underwent a curative resection of primary lesions and metastatic liver diseases at one institute were analyzed using the multivariate method with respect to both the metastatic state and the primary lesion. RESULTS Multivariate analysis indicated that the aggressiveness of the primary tumor, early liver metastasis, and a large number of liver metastases were the characteristics that could be detected before hepatectomy and that independently indicated a worse survival. A three-ranked classification based on these coefficients (H-staging) was significantly related to both the recurrence rate within 6 months (7% in H-stage A, 30% in B, and 44% in C) and the 5-year survival rates (55%, 14%, and 0% respectively). An additional scoring system (H'-staging) based on the aggressiveness of the primary tumor and the level of carcinoembryonic antigen 1 to 3 months after hepatectomy was found to be related to the mode of subsequent recurrence and surgical resectability of the recurrent foci. CONCLUSIONS H-staging can provide useful prognostic information for the treatment of liver metastasis. H-staging could also help in predicting the possible mode of recurrence after hepatectomy and in determining the most suitable mode of additional therapy. Further multiinstitutional studies based on a large collective database will confirm the utility of these two staging systems.

Abstract
OBJECTIVE Five-year survival after simple resection of liver metastases from colorectal carcinoma ranges from 20 to 40%. The aim was to study the reliability and long term results of adjuvant intra-arterial chemotherapy after resection of colorectal liver metastases. PATIENTS AND METHOD From 1991 to 1997, 30 patients after a complete resection of liver metastases from colorectal cancer were included (16 men, 14 women, mean age: 62 years). There were 2 stage I, 19 stages II, 2 stages III, 5 stages IV and 2 stages V according to Gayowski staging system. During laparotomy, a catheter was placed in the gastroduodenal artery in order to perfuse the proper hepatic artery. Chemotherapy included 5 Fluorouracil (12 mg/m2) and Leucovorin (200 mg/m2) and was administered once a week during six months. Mean follow-up was 52 months. RESULTS Adjuvant intra-arterial chemotherapy had to be interrupted before six months in 9 patients because leukopenia (n = 2), infection or obstruction of the catheter (n = 5), duodenal migration of the catheter (n = 1) and occurrence of multiple extrahepatic metastases (n = 1). No death was in relation with the method. Five-year survival rate was 41.8% for the global series. Five-year disease free survival rate was 21.4%. Causes of death were: hepatic recurrence only (n = 3), extrahepatic + hepatic recurrence (n = 4), extrahepatic recurrence (n = 2). Two patients died of another carcinoma (esophagus, ovary), without evidence of recurrence of the colorectal carcinoma. At the present, there is a recurrence in 4 living patients. CONCLUSION Although the benefit on survival is not significant, these results suggest a longest time of remission in patients with adjuvant intra-arterial chemotherapy. Trials comparing and/or combining this method to intravenous chemotherapy should be proposed in patients after resection of colorectal liver metastases.

Abstract
BACKGROUND AND OBJECTIVES Survival after surgery for intrahepatic cholangiocarcinoma (ICC) is usually poor. The objective of this study was to investigate whether the gross appearance of ICC indicates postoperative prognosis. METHODS Seventy patients with ICC underwent hepatectomy, with a 50% curative resection rate. Tumors were classified according to gross appearance [mass-forming (n=28), periductal-infiltrating (n=14), intraductal growth (n=10), and mass-forming plus periductal-infiltrating (n=18)], and the presence of lymph node or intrahepatic metastasis was studied microscopically. RESULTS The incidence of positive lymph nodes was significantly higher in the patients with mass-forming plus periductal-infiltrating tumors than in those with intraductal growth tumors (P=0.0089). The curative resection rate was significantly lower in patients with mass-forming plus periductal-infiltrating tumors than in those with either mass-forming or intraductal growth tumors (P=0.0001, P=0.0048, respectively). The 5-year survival rate after surgery in patients with mass-forming plus peri-ductal-infiltrating tumors (0%) was significantly lower than that in patients with mass-forming tumors (39%) or intraductal growth tumors (69%) (P=0.0036, P=0.0011, respectively). Multivariate analysis using Cox's hazards model revealed that lymph node metastasis (P=0.0109) and curative resection (P=0.0315) were statistically significant independent prognostic factors; however, macroscopic types were not. CONCLUSIONS Patients with mass-forming plus periductal-infiltrating ICCs have a poor prognosis; however, the macroscopic types may not be a statistically significant independent prognostic factor.
