Background
Hepatectomy with exposure of tumor surface (a special type of R1 resection) provides a chance of cure for selected patients with centrally located hepatocellular carcinoma (HCC) that is adherent to or compresses major vessels. However, the operative indications, safety, and patient outcomes are not well defined.Methods
We performed hepatectomy for removal of complex centrally located HCC using a selective and dynamic region-specific vascular occlusion technique. Between May 2006 and March 2012, a total of 118 patients underwent resection with exposure of tumor surface (exposure group) and 169 underwent conventional hepatectomy (without exposure of the tumor and vascular surface). The short- and long-term outcomes of patients were evaluated and compared.Results
The postoperative recovery of liver function was comparable between the two groups. Bile leakage occurred in five patients, all in the exposure group. The 1-, 3-, and 5-year recurrence-free survival rates were 74.4, 45.6, and 30.1 % in the exposure group and 80.9, 57.2, and 31.7 % in the control group (p = 0.041). Corresponding overall survival rates were 92.3, 70.3, and 44.9 % in the exposure group and 97.8, 81.4, and 53.1 % in the control group (p = 0.094).Conclusions
Hepatectomy with exposure of tumor surface is technically demanding, but can be performed safely. It is also associated with a risk of tumor recurrence. Multidisciplinary combined therapy would be the solution and can contribute to improve overall survival. 相似文献2.

Background
Surgical radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) is associated with superior oncological outcome in comparison with percutaneous RFA. The present study aimed to retrospectively evaluate the relative perioperative safety and postoperative outcome of the laparoscopic or thoracoscopic approach versus the open approach to RFA for small HCC.Methods
A retrospective analysis was performed in 55 consecutive patients who underwent open (n = 32) or laparoscopic/thoracoscopic (LTS) RFA (n = 23) for primary unresectable HCC between January 2005 and December 2010. Baseline characteristics, survival/recurrence rates, and complications after treatment were compared between the two groups.Results
There was a trend showing that LTS RFA was performed for tumors located in the anterior segment (e.g., segments III, V, VIII). The LTS RFA group had a significantly lower intraoperative blood loss, shorter operative time, and shorter postoperative hospital stay, compared with the open RFA group. No major postoperative complications occurred in patients who underwent LTS RFA. No significant differences in overall survival, recurrence-free survival and local recurrence rates were observed between the two groups.Conclusions
In consideration of operative invasiveness and postoperative recovery, LTS RFA is superior to the open approach in patients with small HCC. Moreover, the surgical outcome did not differ between the two approaches. Laparoscopic/thorascopic RFA can be considered to be a useful procedure for ablation therapy. 相似文献3.

Background
The purpose of the present study was to analyze long-term survival and disease-free survival after liver resection for giant hepatocellular carcinoma (HCC) ≥ 10 cm compared to HCC < 10 cm in diameter. The surgical approach in the treatment of giant HCC may achieve long-term survival and disease-free survival comparable to treatment of smaller lesions.Methods
This retrospective analysis was a monocentric study conducted in a tertiary university center. It included 101 patients from 114 consecutive liver resections for HCC, separated into two groups: those with tumors less than 10 cm in diameter (small HCC; n = 79) and those with tumors larger than 10 cm (giant HCC; n = 22). The main outcome measures were overall five-year survival, five-year disease-free survival, recurrence rate, perioperative mortality at 30 days, surgical complication rate, and re-intervention rate.Results
The two groups were homogeneously distributed, apart from cirrhosis, which was found more frequently in the group with small HCC (77 vs. 41 %; p = 0.0013). Both median survival (24 vs. 27 months; p = 0.0085) and overall 5-year survival (21 vs. 45; p = 0.04) were significantly poorer in the small HCC group compared to the giant HCC group. There were no differences en terms of recurrence rate, pattern, and timing.Conclusions
Liver resection for HCC larger than 10 cm is a valuable option in selected patients, one that provides overall survival and disease-free survival comparable to smaller lesions. Functional reserves of the liver, more than the size of the lesion, may be important in patient selection for surgical resection. 相似文献4.

Background
Excellent long-term outcomes have been reported recently for patients with small (≤2 cm) hepatocellular carcinoma (HCC). However, the significance of microvascular invasion (MVI) in small HCC remains unclear. The purpose of this study was to determine the impact of MVI in small HCC up to 2 cm.Methods
In 1,109 patients with solitary HCC from six major international hepatobiliary centers, the impact of MVI on long-term survival in patients with small HCC (≤2 cm) and patients with tumors larger than 2 cm was analyzed.Results
In patients with small HCC, long-term survival was not affected by MVI (p = 0.8), whereas in patients with larger HCC, significantly worse survival was observed in patients with MVI (p < 0.0001). In multivariate analysis, MVI (hazard ratio [HR] 1.59; 95 % confidence interval (CI) 1.27–1.99; p < 0.001), elevated alpha-fetoprotein (HR 1.41; 95 % CI 1.11–1.8; p = 0.005), and higher histologic grade (HR 1.29; 95 % CI 1.01–1.64; p = 0.04) were significant predictors of worse survival in patients with HCC larger than 2 cm but were not correlated with long-term survival in small HCC. When the cohort was divided into three groups—HCC ≤2, >2 cm without MVI, and HCC >2 cm with MVI—significant between-group survival difference was observed (p < 0.0001).Conclusions
Small HCC is associated with an excellent prognosis that is not affected by the presence of MVI. The discriminatory power of the 7th edition of the AJCC classification for solitary HCC could be further improved by subdividing tumors according to size (≤2 vs. >2 cm). 相似文献5.

Background
Solitary hepatocellular carcinoma (HCC) is a good candidate for surgical resection. However, the significance of the size of the tumor in solitary HCC remains unclear.Objective
The aim of this study was to evaluate the impact of tumor size on overall and recurrence-free survival of patients with solitary HCC.Materials
We retrospectively reviewed 616 patients with histologically confirmed solitary HCC who underwent curative surgical resection between 1994 and 2010. The characteristics and prognosis of patients with HCC were analyzed stratified by tumor size.Results
A total of 403 patients (65 %) had tumors <5 cm, 172 (28 %) had tumors between 5 and 10 cm, and 41 (7 %) had tumors >10 cm. The incidence of microvascular invasion, satellite nodules, and advanced tumor grade significantly increased with tumor size. The 5-year overall and recurrence-free survival rates of HCC <5 cm were 69.6 % and 32 %, respectively, which were significantly better than those of HCC between 5 and 10 cm (58 % and 26 %, respectively) and HCC >10 cm (53 % and 24 %, respectively). On multivariate analysis, cirrhosis (p = 0.0307), Child–Pugh B (p = 0.0159), indocyanine green retention rate at 15 min >10 % (p = 0.0071), microvascular invasion (p < 0.0001), and satellite nodules (p = 0.0009) were independent predictors of poor survival, whereas tumor size >5 cm was not.Conclusion
Although recurrence rates are high, surgical resection for solitary HCC offers good overall survival. Tumor size was not a prognostic factor. Solitary large HCC >10 cm would be a good candidate for hepatectomy as well as solitary HCC between 5 and 10 cm. 相似文献6.

Background
The surgical resection of huge hepatocellular carcinoma (HCC) is still controversial. This study was designed to introduce our experience of liver resection for huge HCC and evaluate the safety and outcomes of hepatectomy for huge HCC.Methods
A total of 258 hepatic resections for the patients with huge HCC were analysed retrospectively from December 2002 to December 2011. The operative outcomes were compared with 293 patients with HCC >5.0 cm but <10.0 cm in diameter. Prognostic factors for long-term survival were evaluated by univariate and multivariate analyses.Results
The 1-, 3-, 5-year overall survival rates after liver resection were 84, 62, and 33 %. Overall survival and disease-free survival in huge HCC group and HCC >5.0 cm but <10.0 cm group were similar (P = 0.751, P = 0.493). Solitary huge HCC group has significantly a more longer overall and disease-free survival time than nodular huge HCC (P = 0.026, P = 0.022). Univariate and multivariate analysis revealed that the types of tumour, vascular invasion, and UICC stage were independent prognostic factors for overall survival (P = 0.047, P = 0.037, P = 0.033).Conclusions
Hepatic resection can be performed safely for huge HCC with a low mortality and favorable survival outcomes. Solitary huge HCC has the better surgical outcomes than nodular huge HCC. 相似文献7.

Background
Hepatocellular carcinoma (HCC) is a primary tumor of the liver with poor prognosis. For early stage HCC, treatment options include surgical resection, liver transplantation, and percutaneous ablation. Percutaneous ablative techniques (radiofrequency and microwave techniques) emerged as best therapeutic options for nonsurgical patients.Aims
We aimed to determine the safety and efficacy of radiofrequency and microwave procedures for ablation of early stage HCC lesions and prospectively follow up our patients for survival analysis.Patients and methods
One Hundred and 11 patients with early HCC are managed in our multidisciplinary clinic using either radiofrequency or microwave ablation. Patients are assessed for efficacy and safety. Complete ablation rate, local recurrence, and overall survival analysis are compared between both procedures.Results
Radiofrequency ablation group (n = 45) and microwave ablation group (n = 66) were nearly comparable as regards the tumor and patients characteristics. Complete ablation was achieved in 94.2 and 96.1 % of patients managed by radiofrequency and microwave ablation techniques, respectively (p value 0.6) with a low rate of minor complications (11.1 and 3.2, respectively) including subcapsular hematoma, thigh burn, abdominal wall skin burn, and pleural effusion. Ablation rates did not differ between ablated lesions ≤3 and 3–5 cm. A lower incidence of local recurrence was observed in microwave group (3.9 vs. 13.5 % in radiofrequency group, p value 0.04). No difference between both groups as regards de novo lesions, portal vein thrombosis, and abdominal lymphadenopathy. The overall actuarial probability of survival was 91.6 % at 1 year and 86.1 % at 2 years with a higher survival rates noticed in microwave group but still without significant difference (p value 0.49).Conclusion
Radiofrequency and microwave ablations led to safe and equivalent ablation and survival rates (with superiority for microwave ablation as regards the incidence of local recurrence). 相似文献8.

Background
Resection has been the standard of care for patients with solitary hepatocellular carcinoma (HCC). Transarterial embolization and percutaneous ablation are alternative therapies often reserved for suboptimal surgical candidates. Here we compare long-term outcomes of patients with solitary HCC treated with resection versus combined embo-ablation.Methods
We previously reported a retrospective comparison of resection and embo-ablation in 73 patients with solitary HCC <7 cm after a median follow-up of 23 months. This study represents long-term updated follow-up over a median of 134 months.Results
There was no difference in survival among Okuda I patients who underwent resection versus embo-ablation (66 vs 58 months, p = .39). There was no difference between the groups in the rate of distant intrahepatic (p = .35) or metastatic progression (p = .48). Surgical patients experienced more complications (p = .004), longer hospitalizations (p < .001), and were more likely to require hospital readmission within 30 days of discharge (p = .03).Conclusion
Over a median follow up of more than 10 years, we found no significant difference in overall survival of Okuda 1 patients with solitary HCC <7 cm who underwent surgical resection versus embo-ablation. Our data suggest that there may be a greater role for primary embo-ablation in the treatment of potentially resectable solitary HCC. 相似文献9.
Aims
The aim of this study was to compare the effectiveness and safety of hepatic resection versus open-approach RFA (ORFA) for small hepatocellular carcinomas (HCC) within Milan criteria after successful downstaging therapy by transcatheter arterial chemoembolization.Material and Methods
Between February 2005 and February 2008, a total of 110 patients with advanced HCC met the Milan criteria after successful downstaging therapy; 58 patients then underwent hepatic resection and 52 received ORFA. Outcomes, including short- and long-term morbidity, 1-, 3-, and 5-year mortality and HCC-free survival, were analyzed and compared between the two groups.Results
Patients in the hepatic resection and ORFA groups showed similar baseline characteristics and downstaging protocols. The ORFA group showed less blood loss, lower hospital costs, shorter surgical time, and fewer hospital stay days (P?<?0.05). The 1-, 3-, and 5-year overall survival rates were 94.8, 86.2, and 79.3 %, respectively, with liver resection and 96.2, 82.7, and 76.9 % with ORFA (P?=?0.772). The 1-, 3-, and 5-year recurrence-free survival rates were 93.1, 81.0, and 77.6 % with resection and 94.2, 76.9, and 73.1 % with ORFA (P?=?0.705). The ORFA patients suffered fewer postoperative complications (P?=?0.09), particularly among the cases of central HCC (P?=?0.015).Conclusion
Resection and ORFA achieved similar survival benefits in the management of HCC within Milan criteria after successful downstaging. The decreased blood loss, hospital costs, surgical time, and hospital stay days, and lower complication rates in central cases render ORFA a preferred treatment option. 相似文献10.

Purpose
To evaluate differences in overall survival in patients with hepatocellular carcinoma (HCC) after the establishment of a multidisciplinary clinic (MDC) for HCC.Methods
Patient demographic and tumor characteristics of 355 patients diagnosed with HCC were collected between October 2006 and September 2011. Patients diagnosed after the initiation of the HCC MDC on October 1, 2010, were compared to patients diagnosed in the 4 years before. Patient demographics, tumor characteristics, treatment regimens, and overall survival were analyzed between the groups.Results
A total of 105 patients were diagnosed in the time period after HCC MDC initiation compared to 250 patients in the previous 4 years. Patients diagnosed with HCC after the HCC MDC had fewer symptoms at presentation (64 vs. 78 %, p = 0.01) and earlier stage of tumor presentation [Barcelona Clinic for Liver Cancer (BCLC) A stage, 44 vs. 26 %, p = 0.0003; tumor, node, metastasis classification system stage 1, 44 vs. 30 %, p = 0.003) compared with patients diagnosed before MDC formation. The median time to treatment after diagnosis in the later period was significantly shorter than in the earlier time period (2.3 vs. 5.3 months, p = 0.002). On multivariate analysis, being seen in the HCC MDC remained independently associated with better overall survival (hazard ratio 2.5, 95 % confidence interval 2–3), after adjusting for BCLC stage and recipient of curative treatment. Patients diagnosed after HCC MDC initiation had a median survival of 13.2 months compared to the 4.8 months observed in patients diagnosed before MDC formation (p = 0.005).Conclusions
The implementation of a MDC for the evaluation and treatment of patients with HCC is associated with improved overall survival. 相似文献11.

Background
The present study aimed to clarify the clinicopathologic features of long-term disease-fee survival after resection of hepatocellular carcinoma (HCC).Methods
This retrospective study identified 940 patients who underwent curative resection of HCC between 1991 and 2000 at five university hospitals. Seventy-four patients with 10 years of recurrence-free survival were identified and followed up. They were divided into two groups, 60 recurrence-free and 14 with recurrence after a 10-year recurrence-free period.Results
Overall survival rates of recurrence and non-recurrence groups were 68 and 91 % at 16 years, and 34 and 91 % at 20 years (p = 0.02), respectively. There were five (36 %), and two deaths (3 %), respectively, after 10 recurrence-free years. A second resection for recurrence was performed in four patients (29 %), and mean survival was 15.3 years after the first hepatectomy. Although three patients in the non-recurrence group (5 %) developed esophageal and/or gastric varices, seven patients in the recurrence group (50 %) developed varices during 10 years (p < 0.0001). In multivariate analysis, preoperative and 10-year platelet count was identified as a favorable independent factor for maintained recurrence-free survival after a 10-year recurrence-free period following curative hepatic resection of HCC.Conclusions
Recurrence of HCC may occur even after a 10-year recurrence-free period. Long-term follow-up after resection of HCC is important, and should be life-long. Patients with higher preoperative and 10-year platelet counts are more likely to have long-term survival after resection. A low platelet count, related to the degree of liver fibrosis, is a risk factor for recurrence and survival of HCC after curative resection. 相似文献12.

Purpose
This study was designed to retrospectively compare the effectiveness of combined transarterial chemoembolization (TACE) plus radiofrequency ablation (RFA) with that of RFA alone in patients with medium-sized (3.1–5.0 cm) hepatocellular carcinoma (HCC).Methods
From March 2000 to April 2010, 57 patients, each with a single medium-sized HCC, were treated with combined TACE and RFA, and 66 were treated with RFA alone.Results
During follow-up (mean, 42.5 ± 33.2 months; range, 2.6–126.2 months), local tumor progression was observed in 40% of treated lesions in the combined treatment group and in 70% in the RFA-alone group. The 1-, 3-, 5-, and 7-year local tumor progression rates were significantly lower in the TACE + RFA group (9%, 40%, 55%, and 66%, respectively) than in the RFA-alone group (45%, 76%, 86%, and 89%, respectively; P < 0.001). Multivariate analysis showed that treatment allocation (odds ratio [OR], 1.78; P = 0.016) and Child-Pugh class (OR, 1.96; P = 0.008) were significant independent factors associated with patient survival. The rates of major complications were 0% for the combined treatment group and 3% for the RFA-alone group.Conclusions
The combination of TACE and RFA is safe and provides better local tumor control than RFA alone for the treatment of patients with medium-sized HCC. Our multivariate analysis showed that RFA-alone treatment and Child-Pugh class B were poor independent factors for determining the patient survival period. 相似文献13.

Background
The clinical significance of spontaneous hepatocellular carcinoma (HCC) rupture association with recurrence pattern and long-term surgical outcomes remains under debate. We investigated the impact of spontaneous HCC rupture on recurrence pattern and long-term surgical outcomes after partial hepatectomy.Methods
From 2000 to 2012, 119 patients with diagnosed ruptured HCC were reviewed. To compare outcomes between staged hepatectomy in spontaneously ruptured HCC and hepatectomy in non-ruptured HCC, we performed propensity score-matching to adjust for significant differences in patient characteristics. Overall survival, disease-free survival, and recurrence pattern were compared between the matched groups.Results
Forty-four patients with newly diagnosed ruptured HCC and Child A class were initially treated with transcatheter arterial embolization for hemostasis. Three patients underwent emergency laparotomy, 18 underwent staged hepatectomy, and 23 received transarterial chemoembolization (TACE) alone after transcatheter arterial embolization. Among the 23 patients treated with TACE alone, 10 had resectable tumors. The staged hepatectomy group shows significantly higher overall survival with TACE alone than the resectable tumor group (P < 0.001). After propensity score-matching, overall survival, disease-free survival, and recurrence pattern were not significantly different between the ruptured HCC with staged hepatectomy group and the non-ruptured HCC with hepatectomy group. Peritoneal recurrence rates were similar at 14.3 % versus 10.0 %, respectively (P = 0.632).Conclusions
Patients with spontaneously ruptured HCC with staged hepatectomy show comparable long-term survival and recurrence pattern as patients with non-ruptured HCC having similar tumor characteristics and liver functional status. Thus, spontaneous HCC rupture may not increase peritoneal recurrence and decrease long-term survival after partial hepatectomy. 相似文献14.

Background
As a pleiotropic cytokine, transforming growth factor-β (TGF-β) controls the functions of proliferation, adhesion, and differentiation, and contributes to cancer promotion and suppression. Moreover, it is related to the epithelial–mesenchymal transition process and T cell differentiation associated with inflammation. The Smad4 protein is the downstream mediator of TGF-β. In this study, we examined the relationship between Smad4 expression and clinicopathological features in patients with hepatocellular carcinoma (HCC).Methods
Expression of Smad4 was assessed in five HCC cell lines and in paired cancerous and noncancerous tissues in three patients with HCC, using Western blotting analysis. Moreover, Smad4 expression in 121 HCC patients was evaluated by using immunohistochemistry.Results
Only the Li7 and HT17 cell lines expressed the Smad4 protein. All human samples expressed the protein. Immunohistochemistry showed that Smad4 expression tended to be strong in small HCC nodules less than 45 mm in diameter (P = 0.06) and in the infiltrated part of the tumor capsule. Postoperative survival analysis indicated that HCC patients with strong Smad4 expression had shorter disease-specific survival than those with weak expression (P = 0.04). Multivariate analysis also showed that Smad4 expression could be one predictor of prognosis, but the correlation was not significant (P = 0.07).Conclusions
Although TGF-β/Smad4 signaling may have various biological effects on human malignancies, strong Smad4 expression in HCC is likely to suggest poor prognosis. The information has implications for predicting HCC prognosis and developing targeted therapeutics. 相似文献15.

Purpose
To evaluate the effect of body composition on outcomes after hepatic resection for patients with hepatocellular carcinoma (HCC).Methods
We performed 190 hepatic resections for HCC and divided the patients into 2 groups on the basis of visceral fat area (VFA), assessed by computed tomographic measurement at the level of the umbilicus, into high VFA (H-VFA) (n = 106) and low VFA (L-VFA) (n = 84) groups. We compared the surgical outcomes between the two groups.Results
L-VFA was significantly correlated with a lower body mass index, sarcopenia, lower serum albumin, and liver cirrhosis. There was no difference in the incidence of postoperative complications and mortality between the 2 groups. Patients in the L-VFA group had a significantly poorer prognosis than those in the H-VFA group in terms of both overall (P = 0.043) and recurrence-free (P = 0.001) survival. The results of multivariate analysis showed that sarcopenia rather than L-VFA was an independent and prognostic indicator after hepatic resection with HCC.Conclusions
Body composition is an important factor affecting cancer outcomes after hepatic resection for HCC in Japan. 相似文献16.

Background
Surgical therapies for hepatocellular carcinoma (HCC) represent the potentially curative approaches and provide patients the greatest survival advantage. We sought to examine the outcomes of patients with HCC treated with surgical resection, transplantation, and local ablation.Methods
The Surveillance, Epidemiology, and End Results database was queried for all patients with nonmetastatic HCC from 2004 to 2007 who underwent local ablation (LA), segmental resection (SR), hemihepatectomy or extended resection (ER), or transplantation (TP).Results
Of 16,209 patients with HCC, 3,989 (24.6 %) met criteria for inclusion and received therapies: 1,550 LA (39 %), 703 SR (18 %), 619 ER (16 %), and 1,117 TP (28 %). AFP was elevated in 69 % (2,026 of 2,921), and fibrosis grade 0–4 was noted in 32 % (368 of 1,156). The 3-year survival by procedure was 34 % (LA), 50 % (SR), 54 % (ER), and 74 % (TP), p = .001. In patients with minimal fibrosis, 1-year survival for patients undergoing resection was similar to TP (85 vs. 92 %, p = .346), but greater than LA (69 %, p = .001).Discussion
Survival after surgical resection for HCC patients without extensive fibrosis appears to be superior to ablation and non-inferior to transplantation. In an era of organ shortage, transplantation may be better reserved for patients with cirrhosis and/or unresectable disease. 相似文献17.

Background
The purpose of the present study was to determine whether intrahepatic injection of 131I-lipiodol (Lipiodol) is effective against recurrence of surgically resected hepatocellular carcinoma (HCC).Methods
From June 2001 through March 2007, this nationwide multi-center prospective randomized controlled trial enrolled 103 patients 4–6 weeks after curative resection of HCC with complete recovery (52: Lipiodol, 51: Control). Follow-up was every 3 months for 1 year, then every 6 months. Primary and secondary endpoints were recurrence-free survival (RFS) and overall survival (OS), respectively, both of which were evaluated by the Kaplan–Meier technique and summarized by the hazard ratio (HR). The design was based on information obtained from a similar trial that had been conducted in Hong Kong.Results
The Lipiodol group showed a small, and nonsignificant, improvement over control in RFS (HR = 0.75; 95 % confidence interval [95 % CI] 0.46–1.23; p = 0.25) and OS (HR = 0.88; 95 % CI 0.51–1.51; p = 0.64). Only two serious adverse events were reported, both with hypothyroidism caused by 131I-lipiodol and hepatic artery dissection during angiography.Conclusions
The randomized trial provides insufficient evidence to recommend the routine use of 131I-lipiodol in these patients. 相似文献18.

Purpose
The incidence of hepatocellular carcinoma (HCC) in the elderly population has recently been increasing. In this study, we focused on a recent 10-year survey, and compared the clinicopathological features and postoperative outcomes of HCC in elderly (≥75 years of age) and younger patients (<75 years of age).Methods
A total of 255 patients who underwent hepatectomy for HCC from 2001 to 2010 at Wakayama Medical University Hospital were reviewed. The clinical characteristics were compared between the elderly and younger patients. The risk factors for postoperative complications and prognostic factors were identified using the multivariate analyses.Results
A total of 66 patients were classified as elderly patients. The incidence of HCC without viral liver disorders was significantly high in the elderly group than in the younger group. The independent risk factors [odds (95 % confidence intervals)] for postoperative complications were an ASA score of 3 [2.57 (1.20–5.49)] and the length of the operation [1.41 (1.09–1.81)]. The survival was similar between the two groups, and the only independent prognostic factor for survival in the elderly patients was vessel invasion.Conclusions
HCC derived from non-viral liver disorders was dominant in the elderly patients. Aging itself was not a risk factor for postoperative complications or the survival outcome. 相似文献19.

Background
Even after surgery, hepatocellular carcinoma (HCC) has poor prognosis; adjuvant therapy is needed to improve effectively the outcome of HCC patients. We evaluated the efficacy of cytokine-induced killer (CIK) cell infusion as an adjuvant therapy for postoperative HCC patients.Methods
A total of 410 patients were studied retrospectively (January 2002 to January 2007): 206 received surgery alone; 204 received surgery and at least four cycles of CIK cell transfusion (CIK group). Kaplan–Meier and Cox regression analyses were used to explore differences in OS between two groups.Results
The CIK group overall survival rates were significantly higher than that of the surgery-alone group (log-rank test; p = 0.0007). Multivariate survival analysis showed that CIK cell treatment was an independent prognostic factor. In subgroup analysis, patients who received ≥8 cycles of CIK cell transfusion exhibited significantly better survival than the <8 cycle group (p = 0.0272). There was no significant difference in overall survival in patients with ≤5-cm tumors between the CIK and surgery-alone groups (p = 0.7567). However, in patients with >5-cm tumors, the CIK group displayed significantly better overall survival than the surgery-alone group (p = 0.0002).Conclusions
Postoperative immunotherapy with CIK cell transfusion may be an effective adjuvant treatment for improving the outcomes of HCC patients; >8 cycles of CIK cell transfusion may ensure that patients derive maximal benefits. Moreover, patients with large tumors might benefit more from CIK cell adjuvant treatment than patients with small tumors. 相似文献20.
