Background
Hepatitis B (HBV) and hepatitis C (HCV) are well-recognized risk factors for hepatocellular carcinoma (HCC). The characteristics and clinical outcomes of HCC arising from these conditions may differ. This study was conducted to compare the outcomes of HCC associated with HBV and HCV after liver resection.Methods
Of 386 liver resections for HCC performed between July 1992 and April 2011, 181 patients had HBV and 74 patients had HCV. Patients with HBV/HCV coinfections (n = 20), non-HBV/HCV etiology (n = 94), and postoperative death within 3 months (n = 17) were excluded. Patient, tumor characteristics, and perioperative and oncologic outcomes were compared between patients with HBV and HCV.Results
The patients with HBV had better overall survival (OS) than patients with HCV (68 vs. 59 months, p = 0.03); however, there was no difference in recurrence-free survival (RFS) between the groups (44 vs. 45 months, p = 0.1). The factors predictive of OS based on multivariate analyses included: vascular invasion [p < 0.01, hazard ratio (HR) = 3.4], Child-Pugh Score (p < 0.01, HR = 4.8), and underlying liver disease (HCV vs HBV) (p = 0.01, HR = 1.9). Vascular invasion and tumor number (p < 0.01, HR = 2.3 and p < 0.01, HR = 2.1) were independent predictors of RFS.Conclusions
OS but not RFS after liver resection for HCC is better in patients with HBV than HCV. This survival advantage for HBV patients may be due to differences in tumor biology and outcomes after disease recurrence. 相似文献2.

Background
There is conflicting evidence concerning platelet status and hepatocellular carcinoma (HCC) prognosis. We evaluated the prognostic value of platelet-based indices, including platelet count, platelet/lymphocyte ratio (PLR), and aspartate aminotransferase to platelet ratio index (APRI) in HCC after hepatic resection.Methods
We retrospectively reviewed 332 patients with HCC treated with hepatectomy between 2006 and 2009. Preoperative platelet count, as well as demographic, clinical, and pathologic data, were analyzed.Results
Both disease-free survival (DFS) and overall survival (OS) were significantly improved for patients with low platelet count, PLR, and APRI compared to patients with elevated values. On multivariate analysis, APRI, tumor size ≥5 cm, noncapsulation, and multiple tumors were all associated with both poor DFS and OS. The 1-, 3-, and 5-year DFS rates were 52, 36, and 32 % for patients with APRI <0.62 and were 35, 22, and 19 % for patients with APRI ≥0.62. Correspondingly, the 1-, 3-, and 5-year OS rates were 77, 51, and 42, and 63, 35, and 29 % for both groups. Both DFS and OS of patients with APRI <0.62 were significantly better compared to patients with an elevated APRI (P = 0.009 and 0.002, respectively). Patients with elevated APRI tended to have cirrhosis, hepatitis B virus (HBV) infection, surgical margin <1 cm, and noncapsulated tumors.Conclusions
Elevated platelets based inflammatory indices, especially APRI, was associated with adverse characteristic features and poor prognosis in HCC, especially for patients with HBV infection or cirrhosis. Antiplatelet treatment may represent a potential therapy for HBV-induced HCC recurrence. 相似文献3.

Introduction
Recent data support liver resection (LR) as first-line approach in patients with preserved liver function who have resectable/transplantable hepatocellular carcinoma (HCC). This study was designed to evaluate the outcome of LR in patients with transplantable HCC.Methods
Between 1998 and 2009, 75 patients (65 men, mean age 61 ± 11 years) with HCC eligible for liver transplantation (LT) underwent LR. The underlying hepatic disease was related to hepatitis C (HCV) in 30 (40 %) patients, hepatitis B (HBV) in 15 (20 %) patients, alcohol abuse in 26 patients (36 %) and other in 10 patients (13 %). Fifty-five (73 %) patients had cirrhosis. Intermittent clamping of the hepatic pedicle was used in 41 (55 %) patients. Treatment of recurrence by salvage LT was performed in 6 (8 %) patients.Results
Operative morbidity and mortality rates were 37 and 5 % respectively. At 1, 3, and 5 years, overall (OS) and disease-free (DFS) survival rates were 81, 69,55 and 56, 31, and 21 %, respectively. On multivariate analysis, HCV infection was the only independent factor associated with decreased OS (p = 0.02). On multivariate analysis, HCV infection (p = 0.05) and intermittent hepatic pedicle clamping (p = 0.003) were associated with decreased DFS. The 1-, 3-, and 5-year OS and DFS rates in patients with HCV-related HCC were 69, 53, 38 and 50, 18, and 9% respectively.Conclusions
Overall and disease-free survival after liver resection in patients with HCV-related HCC and preserved liver function is poor. Primary LT should be offered to these patients. 相似文献4.

Background
Early detection and following appropriate treatments of hepatocellular carcinoma (HCC) is still the gold standard for favored outcome of HCC patients; nevertheless, a small portion of hepatitis B virus (HBV)-related small HCC (<5 cm) patients got poor prognosis. Furthermore, the study for small HBV–HCC was limited. Therefore, the aim of this study was to explore the potential genetic signature for HBV-related small HCC as novel prognostic factors.Methods
We examined expression profiles of HBV-related small HCC using an Affymetrix U133A GeneChip, evaluated differential gene expression by quantitative real-time polymerase chain reaction (qRT-PCR), and finally validated these expression patterns by immunohistochemistry (IHC).Results:
A total of 57 genes were differentially expressed between tumor and normal parts (n = 20 pairs) using Affymetrix U133A chip, and 16 genes were further evaluated by qRT-PCR. The result was compatible with the finding of oligonucleotide microarray (Pearson’s correlation, r = 0.87). Furthermore, the expression pattern in HCC tissue by IHC in another group of small HBV–HCC (n = 100) showed overexpression of either osteopontin (OPN) or glypican 3 (GPC3) is an independent prognostic factor for disease-free survival (DFS) in HBV-positive small HCC (P < 0.01 and 0.03, respectively). Long-term DFS and overall survival (OS) for small HBV–HCC patients with high risk (both elevated GPC3+/OPN+) were DFS 0%, OS 0%, respectively; on the other hand, DFS and OS in patients with moderate (only 1 gene elevated) or low (OPN?/GPC3?) risk were 35.0 and 46.5%, respectively.Conclusions
Elevation of both OPN and GPC3 may act as an adverse indicator for HBV-related small HCC patients after curative resection.5.

Background
Leukocyte subsets in peripheral blood, which include neutrophils, lymphocytes, and monocytes, have not been well established as prognostic factors in patients with hepatocellular carcinoma (HCC).Methods
Consecutive patients who underwent curative hepatic resection for HCC at the National Cancer Center, Republic of Korea, from 2001 to 2008 were enrolled in this retrospective study. Clinicopathologic factors, cancer-specific survival (CSS), and disease-free survival (DFS) were analyzed with respect to preoperative lymphocyte subsets, especially monocyte ratio.Results
The 603 patients had a median follow-up of 40.0 months and a 5-year overall survival rate of 67.7 %. In univariate analysis of survivals, preoperative lymphocyte ratio ≤35 % and monocyte ratio >7 % were significantly poor prognostic factors. In multivariate analysis, preoperative monocyte ratio >7 %, satellite nodule, and microvascular invasion were independent risk factors for CSS and DFS (hazard ratio of monocyte ratio >7 % = 1.77, p = 0.02 and 1.57, p = 0.006, respectively). Considering monocyte ratio with preoperative α-fetoprotein level, patients with both abnormal α-fetoprotein levels (>12 ng/mL) and monocyte ratio >7 % showed significantly worse CSS and DFS than other groups (p < 0.001). Cirrhotic patients with monocyte ratio >7 % showed significantly poor CSS and DFS compared with non-cirrhotic patients (p = 0.033 and <0.001, respectively).Conclusions
A preoperative monocyte ratio >7 % of peripheral blood is an independent risk factor for CSS and DFS after hepatic resection for HCC. Preoperative monocyte ratio might be considered as a novel biomarker for HCC. 相似文献6.

Background
The prognosis of hepatocellular carcinoma (HCC) with macroscopic vascular invasion is extremely poor even after hepatic resection. We aimed to clarify the efficacy of adjuvant hepatic arterial infusion chemotherapy (HAI) for HCC with vascular invasion.Methods
A total of 73 HCC patients with macroscopic vascular invasion were divided into two groups: 38 with hepatectomy with HAI (HAI group) and 35 with hepatectomy alone (non-HAI group). From 1997 to 2007, HAI was performed via an implanted injection port. The treatment comprised three courses of weekly infusion of HAI, which comprised cisplatin (10 mg daily on days 1–5) followed by 5-fluorouracil (5-FU; 250 mg daily on days 1–5) infusion. From 2007, cisplatin (60 mg/m2), 5-FU (600 mg/m2), and a mixture of mitomycin C (3 mg/m2) and degradable starch microspheres were administered for two courses.Results
Overall, 92 % of patients completed adjuvant HAI. In the HAI and non-HAI groups, the 5-year disease-free survival (DFS) rates were 33.1 % and 11.8 %, respectively (p = 0.029), and the 5-year overall survival (OS) rates were 46.7 % and 32.7 %, respectively (p = 0.318). Among the patients with Vp3/4 or Vv3 (n = 32) in the HAI group, the 3-year DFS and OS rates were 33.7 % and 56.8 %, respectively (p = 0.049). Those in the non-HAI group were 8.3 % and 12.0 %, respectively (p = 0.023). Cox proportional multivariate analysis for DFS revealed that HAI was an independent favorable prognostic factor in all 73 patients (hazard ratio 0.536; p = 0.029).Conclusions
Adjuvant HAI for HCC patients with vascular invasion might reduce the risk of recurrence. 相似文献7.
Background
Surgical cytoreduction and intraperitoneal chemotherapy is increasingly accepted as an effective treatment modality for mucinous appendiceal neoplasm. For the majority of patients with low-grade histology, outcomes have been encouraging. The survival of patients with neoplasms of malignant character is protracted and this study was designed to evaluate the effectiveness of this surgical strategy on outcomes.Methods
Forty-six consecutive patients with mucinous and nonmucinous appendiceal cancer with peritoneal dissemination were studied. Clinicopathological and treatment related factors were obtained from a prospective database. The study’s end points of disease-free survival (DFS) and overall survival (OS) were analyzed using the Kaplan-Meier method.Results
The median DFS and OS after cytoreduction were 20.5 and 56.4 months respectively. Five-year overall survival rate was 45%. Five independent factors associated with DFS and OS were identified through a multivariate analysis: age (DFS p = 0.001, OS p = 0.002), completeness of cytoreduction (DFS p = 0.001, OS p = 0.003), previous chemotherapy treatment (DFS p = 0.021), CA 199 levels (DFS p = 0.013), and tumor grade (OS p = 0.005).Conclusions
Cytoreductive surgery and intraperitoneal chemotherapy may achieve long-term survival in appendiceal malignancies with peritoneal dissemination for which the predictors of outcomes identified through this study may tailor the disease management to commit patients early toward this successful surgical strategy. 相似文献8.

Background
The relationship between serum carcinoembryonic antigen (CEA) and postoperative prognosis in hepatocellular carcinoma (HCC) has not been reported.Methods
Data of 5410 consecutive HCC patients who underwent hepatectomy was retrospectively reviewed. Survival curves for overall survival (OS) and tumor recurrence (TR) were depicted using the Kaplan-Meier method and compared using the log-rank test. Independent risk factors of OS and TR were analyzed with Cox hazard regression model. Besides, a one-to-one propensity score-matched (PSM) subset was performed to reduce selection bias. Subgroup analysis was done according to hepatitis B virus (HBV) infection or not.Results
Serum CEA ≥5.1 μg/L was an independent risk factor of OS and TR in the entire cohort and PSM subset (OS—hazard ratio?=?1.218, 95 % confidence interval?=?1.060–1.400; 1.383, 1.133–1.688, respectively; TR—1.256, 1.114–1.417; 1.258, 1.067–1.484, respectively). Subgroup analysis showed that CEA ≥5.1 μg/L was an independent risk factor of OS and TR in the HBV infection group (OS—1.234, 1.065–1.429; TR—1.231, 1.083–1.399) but not in the non-HBV infection group (OS—1.376, 0.895–2.117; TR—1.437, 0.989–2.088).Conclusion
Serum CEA ≥5.1 μg/L was an independent risk factor of OS and TR of HCC patients, and patients with CEA ≥5.1 μg/L had poorer prognosis, especially for HCC patients with HBV infection.9.

Background
Intrahepatic cholangiocarcinoma caused by clonorchiasis (CICC) has a poor prognosis, and there have been insufficient studies regarding risk and prognostic factors. We aimed to identify CICC-associated factors.Methods
A retrospective analysis of 127 eligible patients with CICC was performed with 254 clonorchiasis cases used as matched controls to identify risk factors for CICC. The main outcomes analyzed included overall survival (OS) and disease-free survival (DFS).Results
Out of 127 surgeries, R0 resection was performed in 61 patients, R1 in 32 patients, and R2 in 22 patients; nonresection surgery was performed in 12 patients. Median OS for the entire cohort was 29.5 months. Median OS and DFS for 61 patients with R0 resection were 52.4 months and 41.5 months, respectively. We found independent risk factors for CICC were duration of raw fish consumption of ≥28 years (p < 0.001) and hepatitis B virus infection (p = 0.040). R0 resection (p < 0.001), well or moderately differentiated tumor (p = 0.019), and stage I to II tumor (p < 0.001) predicted improved OS for CICC. Serum carcinoembryonic antigen level of ≤5 ng/ml (p = 0.029) and stage I to II tumor (p < 0.001) predicted improved DFS.Conclusions
Duration of raw fish consumption ≥28 years and hepatitis B virus infection were significant risk factors for CICC in patients with clonorchiasis. For patients with CICC, curative resection is an effective treatment. Higher tumor differentiation and earlier American Joint Committee on Cancer stage predicted good prognosis. Serum carcinoembryonic antigen level was found to predict the possibility of recurrence after curative resection. 相似文献10.

Purpose
This study was designed to evaluate the surgical parameters and treatment outcomes of tumor hemodynamics-based pure laparoscopic (PURE) and laparoscopy-assisted (HYBRID) hepatectomy for small hepatocellular carcinoma (HCC) compared with those of open hepatectomy.Methods
Using a prospectively collected database from 1997 to 2011, we analyzed the data of 56 consecutive cases of laparoscopic hepatectomy for HCC (PURE, n = 24; HYBRID, n = 29; HALS, n = 3) from among 102 cases undergoing laparoscopic hepatectomy. We employed 27 cases treated by open hepatectomy during the same period as controls.Results
PURE was associated with lesser blood loss, lower weight of the resected liver, and a shorter skin incision than HYBRID and open hepatectomy [median blood loss (mL): PURE 7, HYBRID 380, Open 450; P < 0.05]. On the other hand, HYBRID hepatectomy was associated with a longer operation time [operation time (min): HYBRID 232, Open 185; P = 0.0226]. The length of hospitalization in the cases treated by PURE and HYBRID hepatectomy was shorter than that in the cases treated by open hepatectomy [length of hospitalization (days): PURE 11, HYBRID 12, Open 17; P < 0.05]. One case each of transfusion and morbidity was recorded in this series. There was no significant difference of the overall (OS) or disease-free survival (DFS) between the patients treated by laparoscopic and open hepatectomy (3-year OS: 100 vs. 100 %; DFS 50 vs. 62 %, respectively).Conclusions
Neither the surgical parameters nor the treatment outcomes of hemodynamics-based laparoscopic hepatectomy were inferior to those of open hepatectomy. 相似文献11.

Background
The impact of minimally invasive esophagectomy on patient prognosis, particularly disease-free survival (DFS), has not been well addressed. We compared the clinical outcomes of open and thoracoscopic esophagectomy in patients with esophageal squamous cell carcinoma (ESCC).Methods
Sixty-three and 66 patients, nonrandomized, underwent open and thoracoscopic esophagectomies for ESCC between 2008 and 2011 were included. The clinicopathological data were reviewed retrospectively. Perioperative outcome, overall survival (OS), DFS, and the recurrence sites after open and thoracoscopic esophagectomy were compared.Results
The open and thoracoscopic groups were comparable with regard to the total number of harvested lymph nodes and the percentage patients undergoing R0 resection. Fewer patients in the thoracoscopic group had pneumonia and wound complications. Intensive care unit (ICU) stay also was shorter in the thoracoscopic group. The recurrence pattern was similar in the two groups. In the open and thoracoscopic groups, the 3-year OS rates were 47.6 and 70.9 % (p = 0.031), respectively, and the 3-year DFS rates were 35 and 62.4 % (p = 0.007), respectively. However, the trends in better OS and DFS in the thoracoscopic group were not significant after stratification according to pathologic stage.Conclusions
The perioperative benefit of thoracoscopic esophagectomy included fewer postoperative complications and shorter ICU stays. Mid-term OS and DFS associated with thoracoscopic techniques are at least equivalent to those associated with open procedures. 相似文献12.

Background
Crosstalk between a tumor and the microenvironment plays a key role in tumor progression and metastasis. This study was performed to elucidate the prognostic significance of combining tumor-secreted osteopontin (OPN) with microenvironment-associated peritumoral macrophages (PTMs) in hepatocellular carcinoma (HCC), especially for those with early-stage disease.Methods
Tissue microarray-based immunohistochemistry was used to investigate OPN and PTMs expression in two independent cohorts consisting of 374 patients with HCC who underwent radical resection. The prognostic value for the two factors alone or in combination was investigated in these patients.Results
OPN combined with PTMs was an independent prognostic factor for both overall survival (OS; p < 0.0001) and time to recurrence (TTR; p = 0.003) from the learning cohort (n = 96). Their combined value for prognosis was validated in early-stage HCCs using another independent cohort (n = 278; OS, p < 0.001; TTR, p = 0.001). This combination remained significant in HCCs with low α-fetoprotein levels in both cohorts, and was predictive for early recurrence/death risk (<2 years) compared with a single marker. Only OPN+HCCs had a significant correlation of PTMs levels with OS (p = 0.01) or TTR (p = 0.011).Conclusions
Tumor OPN combined with PTMs is a promising predictor of tumor recurrence and survival in patients with HCC, especially for those with early-stage disease. The interplay of OPN and PTMs represents a new insight into tumor progression and therapeutic targets for HCC. 相似文献13.

Background
Repeated hepatic resection (HR) and thermal ablation therapy (TAT) are increasingly being used to treat recurrent intrahepatic cholangiocarcinoma (RICC). This study compared the efficacy and safety of these procedures for RICC treatment.Methods
Patients were studied retrospectively after curative resection of RICCs by repeated HR (n = 32) or TAT (n = 77). Treatment effectiveness and prognosis were compared between the two treatment groups.Results
The repeated HR and TAT groups did not differ in their overall survival (OS; p = 0.996) or disease-free survival (DFS; p = 0.692) rates. However, among patients with recurrent tumors >3 cm in diameter, patients in the repeated HR group had a higher OS rate than patients in the TAT group (p = 0.037). The number of recurrent tumors and the recurrence interval were significant prognostic factors for OS. The major complications incidence rate was greater in the repeated HR group than in the TAT group (p < 0.001).Conclusions
Repeated HR and TAT are both effective treatments for RICC with similar overall efficacies. TAT should be preferred in any cases when the RICC is ≤3 cm in diameter and technically feasible. However, for large tumors (>3 cm), repeated HR may be a better choice. 相似文献14.

Background
We have developed a method of distinguishing normal tissue from pancreatic cancer in vivo using fluorophore-conjugated antibody to carcinoembryonic antigen (CEA). The objective of this study was to evaluate whether fluorescence-guided surgery (FGS) with a fluorophore-conjugated antibody to CEA, to highlight the tumor, can improve surgical resection and increase disease-free survival (DFS) and overall survival (OS) in orthotopic mouse models of human pancreatic cancer.Methods
We established nude-mouse models of human pancreatic cancer with surgical orthotopic implantation of the human BxPC-3 pancreatic cancer. Orthotopic tumors were allowed to develop for 2 weeks. Mice then underwent bright-light surgery (BLS) or FGS 24 h after intravenous injection of anti-CEA-Alexa Fluor 488. Completeness of resection was assessed from postoperative imaging. Mice were followed postoperatively until premorbid to determine DFS and OS.Results
Complete resection was achieved in 92 % of mice in the FGS group compared to 45.5 % in the BLS group (p = 0.001). FGS resulted in a smaller postoperative tumor burden (p = 0.01). Cure rates with FGS compared to BLS improved from 4.5 to 40 %, respectively (p = 0.01), and 1-year postoperative survival rates increased from 0 % with BLS to 28 % with FGS (p = 0.01). Median DFS increased from 5 weeks with BLS to 11 weeks with FGS (p = 0.0003). Median OS increased from 13.5 weeks with BLS to 22 weeks with FGS (p = 0.001).Conclusions
FGS resulted in greater cure rates and longer DFS and OS using a fluorophore-conjugated anti-CEA antibody. FGS has potential to improve the surgical treatment of pancreatic cancer. 相似文献15.

Background
Gene amplifications are implicated in cancer development and progression. In this study we investigated the clinicopathologic characteristics associated with EGFR or TTF-1 amplification in lung adenocarcinomas and its prognostic significance.Methods
We analyzed 118 cases of surgically resected primary lung adenocarcinomas. Amplification of the EGFR or TTF-1 gene was evaluated by fluorescence in situ hybridization and correlated with patients’ clinicopathologic features, including disease-free survival (DFS) and overall survival (OS), in all patients and a subset that were TTF-1 positive or had EGFR mutation. Progression-free survival (PFS) also was analyzed among patients with EGFR mutation who had recurred cancer that was treated with EGFR tyrosine kinase inhibitors.Results
EGFR or TTF-1 gene amplification was an independent poor prognostic factor for DFS in all patients (p = 0.001), in patients with TTF-1 positivity (p = 0.010), and in patients with EGFR mutation (p < 0.001) and for OS in patients with TTF-1 positivity (p = 0.021) and patients with EGFR mutation (p < 0.001). Patients with TTF-1 amplification had a shorter PFS following EGFR TKI treatment (p = 0.040).Conclusions
EGFR or TTF-1 gene amplification was a predictive factor for poor prognosis in terms of DFS and OS, especially in patients with TTF-1 positivity or EGFR mutation. Our results also suggested that TTF-1 amplification might be a predictive marker of poor response to EGFR-TKI therapy in patients with recurrent tumor after surgical resection. 相似文献17.

Background
This study was designed to identify which are the best preoperative inflammation-based prognostic scores in terms of overall survival (OS) and disease-free survival (DFS) in patients with gastric cancer.Methods
Between January 2004 and January 2013, 102 consecutive patients underwent resection for gastric cancer at S. Andrea Hospital, "La Sapienza", University of Rome. Their records were retrospectively reviewed.Results
After a median follow up of 40.8 months (8–107 months), patients’ 1-, 3-, and 5-year OS rates were 88, 72, and 59 %, respectively. After R0 resection, the 1-, 3-, and 5-year DFS rates were 93, 74, and 56 %, respectively. A multivariate analysis of the significant variables showed that only the modified Glasgow prognostic scores (p < 0.001) and PI (p < 0.001) were independently associated with OS. Regarding DFS, multivariate analysis of the significant variables showed that the modified Glasgow prognostic score (p = 0.002) and prognostic index (p < 0.001) were independently associated with DFS.Conclusions
The results of this study show that modified Glasgow prognostic score and prognostic index are independent predictors of OS and DFS in patients with gastric cancer. 相似文献18.

Background
Few reports exist on long-term survival after minimally invasive liver surgery (MILS) for colorectal liver metastases (CRLM). No data are available assessing prognostic factors in the era of current modern treatment strategies.Methods
Between October 2002 and December 2008, 274 consecutive patients were analyzed on an intention-to-treat basis. Open liver surgery (OLS) was performed in 193 patients for a total of 437 metastases, and MILS was performed in 81 patients for 176 metastases. Systemic chemotherapy was administered preoperatively in 173 and postoperatively in 174 patients. The impact of 23 potential prognostic factors on disease-free (DFS) and overall survival (OS) was evaluated using univariable and multivariable Cox regression models.Results
Postoperative complications were observed in 54 patients after OLS and in 11 after MILS (p = 0.016). The median postoperative length of hospital stay was 9 days after OLS and 5 days after MILS (p < 0.0001). For the entire patient population, the 5 year DFS and OS rates were 29.9 and 59.5%, respectively. No differences in survival between patients treated with MILS and OLS were observed (p = 0.63). In univariable analyses, the number of liver metastases and the overall Fong’s clinical risk score (CRS) were the only two variables that predicted DFS (p ≤ 0.0035) and OS (p ≤ 0.0005). In multivariable analyses, the total CRS was the only independent predictor of both DFS (p = 0.0002) and OS (p = 0.002).Conclusion
The long-term oncologic outcome of surgically treated patients with CRLM is determined by the Fong’s CRS. Although MILS does not influence long-term survival, it has a beneficial impact on the immediate postoperative clinical outcome. 相似文献19.

Background
The extent of hepatectomy for solitary hepatocellular carcinoma (HCC) <5 cm is controversial.Methods
This is a retrospective review of patients with solitary HCC <5 cm, who underwent liver resection in a tertiary referral centre in Hong Kong between January 1989 and December 2009. Baseline demographics, liver function, peri-operative outcomes, and overall survival were compared.Results
A total of 348 cirrhotic patients with a solitary HCC <5 cm underwent either major hepatectomy (n = 93) or minor hepatectomy (n = 255). Child-Pugh status did not differ, 98.9 vs. 96.1 % (p = 0.319); all patients who underwent major and minor hepatectomy were classified as Child-Pugh status A. Patients who underwent major hepatectomy had a larger median tumor size (4.0 vs. 2.5 cm, p < 0.001) and they also had more advanced stage of disease (stage I/II/IIIa: 10.8/55.9/33.3 vs. 26.7/52.9/20.4 %, p = 0.002). Median operative time for major hepatectomy was significantly longer (415 vs. 248 min, p < 0.001) and entailed greater blood loss (0.9 vs. 0.5 l, p < 0.001). Despite larger tumor size and more advanced stage of disease in the major hepatectomy group, hospital mortality (5.4 vs. 2.0 %, p = 0.185), complication rates (30.1 vs. 23.1 %, p = 0.234), and transfusion rate (10.8 vs. 11.4 %, p = 0.862) were the same between the two groups. Overall survival was significantly better for those who underwent major hepatectomy, with a median survival of 147.5 vs. 92.1 months (p = 0.043), and they had a better 5- and 10-year disease-free survival rate (57.3 vs. 40.2, 38.1 vs. 18.9 %, p = 0.003). In subgroup analysis, the 10-year survival for patients with stage II HCC and tumor <5 cm was 68.6 vs. 36.6 % in those who received minor hepatectomy alone (p = 0.027).Conclusions
Major hepatectomy provided better long-term survival benefit in patients with HCC <5 cm, particularly in those with stage II disease. 相似文献20.
