[Undistinguishable Cryptococcus-related granulomatous lesion from carcinoma in the tail of the pancreas: a case report].

Abdominal computed tomography revealed a 19×13mm delayed enhancing mass and dilation of the distal pancreatic duct in the head of the pancreas. Magnetic resonance cholangiopancreatography showed pancreatic duct stenosis in the tail of the pancreas. Endoscopic retrograde pancreatography revealed an abrupt interruption of the main pancreatic duct at the tail of the pancreas. We could not assess the distal side of the pancreatic stenosis due to the large extent of obstruction. The pancreatic head mass was diagnosed as adenocarcinoma using endoscopic ultrasound-fine needle aspiration biopsy. However, we could not determine whether the pancreatic duct stenosis in the tail of the pancreas was malignant. Nevertheless, we performed a total pancreatectomy with splenectomy. Histological examination showed poorly differentiated adenocarcinoma in the pancreatic head mass but the pancreatic duct stenosis in the tail of the pancreas was diagnosed as pancreatic granuloma caused by Cryptococcus. Fungal infections may reportedly promote the development of pancreatic cancer, as further suggested by this case of cryptococcal infection.

Oncological Outcomes of Operative Microwave Ablation for Intermediate Stage Hepatocellular Carcinoma: Experience in 246 Consecutive Patients.

BACKGROUND: Few clinical studies concerning the efficacy of microwave ablation for intermediate stage hepatocellular carcinoma have been published. Our purpose was to examine perioperative and long-term outcomes after operative microwave ablation for intermediate stage hepatocellular carcinoma. METHODS: This retrospective study included 246 patients who had undergone operative microwave ablation for intermediate stage hepatocellular carcinoma in our institute between January 2001 and December 2017. We analyzed overall and recurrence-free survival and used the Cox proportional hazard model to evaluate potential prognostic factors. RESULTS: The overall median follow-up time was 51 months. The 1-, 3-, 5-, and 10-year overall survival rates were 98%, 74%, 51%, and 28%, respectively, whereas the 1-, 3-, 5-, and 10-year recurrence-free survival rates were 80%, 32%, 18%, and 10%, respectively. The major complication rate (Clavien-Dindo classification IIIa or above) after operative microwave ablation was 7%, with no procedure-related mortality. Multivariate analysis identified beyond up-to-7 criteria (the sum of the largest tumor's diameter in cm and the total number of tumors), Child-Pugh grade B, and serum alpha-fetoprotein concentration ≥ 100 ng/mL as independent risk factors for overall survival after operative microwave ablation. The overall survival of patients within up-to-7 and Child-Pugh grade A was better than that of the remaining patients, 5-year overall survivals being 67% and 37%, respectively (P < 0.001). CONCLUSIONS: Operative microwave ablation is safe and effective in patients with intermediate stage hepatocellular carcinoma. In particular, patients within up-to-7 and Child-Pugh grade A can be expected to have better long-term outcomes after operative microwave ablation.

Operative Microwave Ablation for Hepatocellular Carcinoma Within 3 cm and 3 Nodules: Experience in 559 Patients.

BACKGROUND: There are few published data regarding long-term outcome survival after microwave ablation (MWA) for hepatocellular carcinoma (HCC) within 3 cm and 3 nodules. The aim of this study was to examine long-term outcomes after operative MWA for HCC within 3 cm and 3 nodules. METHODS: This cohort of this retrospective study comprised 559 patients who underwent operative MWA for HCC within 3 cm and 3 nodules in our institute between 1996 and 2017. We analyzed overall survival (OS) and recurrence-free survival (RFS), and evaluated factors related to prognosis. RESULTS: Median follow-up time was 69 months for the entire cohort. OS rates were 1-year: 98%, 3-year: 87%, 5-year: 73%, and 10-year:39%; RFS rates were 1-year: 91%, 3-year: 60%, 5-year: 42%, and 10-year: 21%. Multivariate analysis revealed that hepatitis C virus (HCV)-positive status, ALBI grade 2 or 3, maximum tumor diameter ≥ 20 mm, and multiple nodules were independent risk factors for both OS and RFS. A prognostic staging model using one point for each risk factor provided a well-categorized predictive model. The 5-year OS rates were 93%, 81%, and 57% for scores of 0, 1 or 2, and 3 or 4, respectively (P < 0.001). The 5-year RFS rates were 70%, 48%, and 28% for scores of 0, 1 or 2, and 3 or 4, respectively (P < 0.001). CONCLUSIONS: Our results revealed good long-term outcomes after operative MWA for HCC within 3 cm and 3 nodules.

Predictive impact of the prognostic nutritional index in early-staged hepatocellular carcinoma after operative microwave ablation.

BACKGROUND: The prognostic nutritional index (PNI) is used to assess immune and nutritional status, and is a prognostic factor for several malignant tumors. However, little evidence exists regarding the predictive impact of prognostic nutritional index (PNI) after local ablation therapy for hepatocellular carcinoma (HCC). The aim of this study was to evaluate the value of PNI to predict recurrence and survival after operative microwave ablation in patients with early-stage HCC. METHODS: This retrospective study included 341 patients who underwent operative microwave ablation for HCC in Barcelona Clinic Liver Cancer (BCLC) stage 0-A at our institute between 2007 and 2015. We analyzed overall survival (OS) and recurrence-free survival (RFS), and evaluated factors related to prognosis in multivariate Cox regression analyses. RESULTS: The OS rates at 1, 3, 5, and 10 years after microwave ablation were 100%, 92.7%, 85.1%, and 57.5% in patients with high-PNI levels, and 96.5%, 78.2%, 59.7%, and 20.7% in patients with low-PNI levels, respectively (P < 0.001). The RFS rates at 1, 3, 5, and 10 years after microwave ablation were 96.3%, 75.2%, 55.4%, and 30.4% in patients with high-PNI levels, and 94.4%, 48.8%, 36.4%, and 13.1% in patients with low-PNI levels, respectively (P < 0.001). In multivariate analyses, preoperative PNI level was an independent prognostic factor for both OS and RFS. CONCLUSION: Our results revealed the preoperative PNI level was a simple and novel predictive marker of survival and recurrence after microwave ablation in patients with early-stage HCC.

Predictive Factors for Local Recurrence after Intraoperative Microwave Ablation for Colorectal Liver Metastases.

This study aimed to clarify local recurrence (LR) predictive factors following intraoperative microwave ablation (MWA) for colorectal liver metastases. The data from 195 patients with 1392 CRLM lesions, who were preoperatively diagnosed by gadolinium-enhanced MRI with diffusion-weighted imaging and dynamic CT and treated with intraoperative MWA (2450 MHz) with or without hepatectomy, from January 2005 to December 2019, were retrospectively reviewed and analyzed using logistic regression. In addition, the margins were measured on contrast-enhanced CT 6 weeks post-ablation. Overall, 1066 lesions were ablated. The LRs occurred in 44 lesions (4.1%) among 39 patients (20.0%). The multivariate analysis per patient showed that tumor size > 20 mm and ablation margin < 5 mm were significant predictors for LR. Furthermore, multivariate analysis per lesion revealed that segments 1, 7, and 8 and tumor size > 15 mm, ablation margin < 5 mm, tumor size > 20 mm, and proximity to the Glisson were significant LR predictors. Finally, the outcome of this study may help determine indications for MWA.

Combined hepatectomy and microwave ablation for multifocal hepatocellular carcinoma: Long-term outcomes and prognostic factors.

BACKGROUND: It remains to be clarified whether combined hepatectomy and microwave ablation for multifocal hepatocellular carcinoma (HCC) is feasible. This aim of this study was to examine the perioperative and oncological outcomes after combined hepatectomy and microwave ablation for multifocal HCC. METHODS: This retrospective study included 81 patients who underwent combined hepatectomy and microwave ablation for multifocal HCC in our institute between June 1998 and December 2017. We analyzed overall survival (OS) and recurrence-free survival (RFS), and evaluated factors related to prognosis. RESULTS: Median follow-up time was 45.6 months for the entire cohort. OS rates were 1-year: 96%, 3-year: 72%, and 5-year: 54%; RFS rates were 1-year: 77%, 3-year: 37%, and 5-year: 22%. The major complication rate (Clavien-Dindo classification IIIa or above) after surgery was 10%, with one patient of in-hospital mortality. Multivariate analysis revealed that des-γ-carboxy prothrombin level >200 mAU/mL and >5 tumors were independent risk factors for OS, and des-γ-carboxy prothrombin level >200 mAU/mL, > 5 tumors, and maximum tumor size >5 cm were independent risk factors for RFS. CONCLUSIONS: Our results indicate that combined hepatectomy and microwave ablation is safe and feasible for selected patients with multifocal HCC.

Glomus tumor of the duodenum: a rare case report.

BACKGROUND: Glomus tumors (GTs) are mesenchymal neoplastic lesions arising from the glomus bodies and generally occur in the fingers and toes. Gastrointestinal GTs are rare, and most of them originate from the stomach; however, GT arising from the duodenum is exceedingly rare. CASE PRESENTATION: A 68-year-old man was admitted due to abdominal pain. Endoscopy showed a round, smooth, elevated mass in the second portion of the duodenum with central ulceration. Abdominal contrast computed tomography showed a hypervascular tumor measuring 26 mm in diameter in the second portion of the duodenum, and pancreatic invasion was suspected. Endoscopic ultrasonography of the lesion confirmed a hypoechoic mass arising from the fourth layer of the duodenal wall. A biopsy was performed for central ulceration, and immunochemical studies showed positive results for smooth muscle actin (SMA) and negative results for S100, C-Kit, and CD34. Leiomyoma or gastrointestinal stromal tumor was suspected and pancreatoduodenectomy was performed. The specimen exhibited a vascular-rich tumor, 24 × 24 × 19 mm in size, with deep ulceration in the duodenum. Histological examination showed uniform small round cells with central nuclei and a pale cytoplasm (glomus cell) with perivascular proliferation. Immunochemical studies showed that the tumor was positive for SMA and collagen type IV, and negative for C-Kit, CD34, desmin, and S100. We diagnosed the tumor as a GT of the duodenum. CONCLUSION: GTs of the duodenum are exceedingly rare, but should be considered in the differential diagnoses of duodenal submucosal lesions.

Feasibility and safety of surgical microwave ablation for hepatocellular carcinoma in elderly patients: a single center analysis in Japan.

The feasibility and safety of microwave ablation in elderly hepatocellular carcinoma (HCC) patients remains unknown. The aim of this study was to evaluate the feasibility and safety of surgical microwave ablation for HCC in patients older than 80 years of age. This retrospective study enrolled consecutive 114 patients older than 80 years of age who underwent surgical microwave ablation for HCC between July 1994 and December 2017. We analyzed perioperative outcomes and long-term outcomes to clarify the prognostic factors. The 1-, 3-, 5-year overall survival and recurrence-free survival rates were 97.3%, 76.0%, 49.2% and 84.2%, 44.7%, and 32.5%, respectively. The overall major morbidity rates (Clavien-Dindo grade IIIA or above) were 2.6%. There were no cases of mortality. Multivariate analysis showed that hepatitis C virus antibody (HCV-Ab) positivity and the presence of multiple tumors were independent prognostic factors for long-term outcomes. The overall survival rate of patients with HCV-Ab negative and single tumor was better than that of other patients (p = 0.026). Surgical microwave ablation was feasible and safe for elderly patients with HCC. Elderly patients with HCV-Ab negative and single tumor would be expected to have better long-term outcomes after surgical microwave ablation.

A case of small cell neuroendocrine carcinoma of the ampulla of Vater.

BACKGROUND: Gastroenteric neuroendocrine carcinomas (NECs) account for 6.2% of gastroenteric neuroendocrine tumors (NETs), and only 1% or less of gastroenteric NETs occur in the ampulla of Vater (AoV). Clinical features of NEC of the AoV remain obscure. CASE PRESENTATION: A 65-year-old man visited a general practitioner because of jaundice, and an abdominal contrast-enhanced computed tomography scan revealed a tumor of 11 mm in diameter, which was enhanced in the arterial phase at the duodenal papilla, with dilation of the upstream bile duct. Gastrointestinal scope revealed an unexposed tumor of the AoV. Based on a biopsy of the site, a moderately differentiated tubular adenocarcinoma was suspected, and pancreatoduodenectomy was performed. Histopathological examination revealed dysplasia and highly proliferative small tumor cells, with solid and nodular formation at the AoV. Histological analysis showed a high mitotic count, and immunohistochemical staining revealed a Ki-67 index of 40-50% and cells positive for synaptophysin, chromogranin A, and p53. Small cell-type NEC was finally diagnosed. Four months post pancreatoduodenectomy, multiple liver metastases developed, and systemic chemotherapy was administered. Salvage liver resection for liver metastases was performed 14 months after the pancreatoduodenectomy. Unfortunately, multiple liver metastases developed 2 months after liver resection, and the patient died 18 months after the pancreatoduodenectomy. CONCLUSIONS: Neuroendocrine carcinoma originating from the bile duct is very rare; therefore, in this article, we provide a review of the literature and a case report.

A Case of Advanced Hepatocellular Carcinoma with Partial Response after Continuous Ramucirumab Treatment beyond Radiological Progression.

A 73-year-old male was initially treated with sorafenib for advanced stage HCC. However, the disease progressed 2 months after starting sorafenib. Progressive disease (PD) was confirmed by radiological examination, which revealed mediastinal and abdominal lymph node metastasis, pulmonary metastasis, and intrahepatic recurrence. The patient was enrolled in the REACH-2 (NCT02435433) trial and randomized to receive ramucirumab (8 mg/kg div. every 2 weeks). The patient had a Child-Pugh score of 6A and his AFP level was found to be 1,256.8 ng/mL at initiation. Radiological examination revealed PD, 5 months after starting ramucirumab. Ramucirumab treatment was continued after the confirmation of radiological PD, not but clinical progression, as allowed by the study protocol. His AFP level increased after continuous ramucirumab treatment, however, it suddenly decreased from 7,653 ng/mL to within normal limits 10 months after initiation of ramucirumab treatment. Radiological evaluation revealed a significant decrease in the size of the tumors, which constituted a partial response (PR). We reported a rare case of advanced HCC with PR to a continuous ramucirumab treatment after radiological PD.

Efficacy of surgical microwave ablation for recurrent hepatocellular carcinoma after curative hepatectomy.

BACKGROUND: Little evidence exists regarding postrecurrence survival after microwave ablation for recurrent hepatocellular carcinoma (HCC) after curative hepatectomy; we aimed to evaluate the feasibility of surgical microwave ablation. METHODS: In this retrospective review, we enrolled patients who underwent curative hepatectomy for primary HCC in our department and had intrahepatic recurrence. We analyzed overall survival according to treatment modality to clarify the prognostic factors for survival. RESULTS: Of 257 patients, 119 had intrahepatic recurrence. Three patients underwent repeat hepatectomy; 75 patients underwent surgical microwave ablation, and 34 patients underwent transcatheter arterial chemoembolization or hepatic arterial infusion chemotherapy. The median postrecurrence survival time and 5-year postrecurrence survival after surgical microwave ablation were 37.4 months and 55.4%, respectively. The major complication rate (Clavien-Dindo classification IIIa or above) after surgical microwave ablation was 5.3% with no mortality. Multivariate analysis showed that microvascular invasion at primary tumors, and recurrent tumors within 3 cm and 3 nodules were independent prognostic factors for overall survival after surgical microwave ablation for recurrent HCC. CONCLUSION: Our results suggested that surgical microwave ablation is safe and feasible for recurrent intrahepatic HCC after curative hepatectomy. Close follow-up and further curative treatment could be important for improving postrecurrence survival.

A multicenter prospective registration study on laparoscopic pancreatectomy in Japan: report on the assessment of 1,429 patients.

BACKGROUND: Prospective studies are needed to understand the safety and feasibility of laparoscopic pancreatectomy. The aim of the present study was to describe laparoscopic pancreatectomy currently undertaken in Japan, using a prospective registration system. METHODS: Patient characteristics and planned operations were registered preoperatively, and then the performed operation and outcomes were reported using an online system. Collected data were also compared between institutions based on their level of experience. This study was registered with UMIN000022836. RESULTS: Available data were obtained from 1,429 patients at 100 Japanese institutions, including 1,197 laparoscopic distal pancreatectomies (LDPs) and 232 laparoscopic pancreatoduodenectomies (LPDs). The rates of completion for planned operations were 92% for LDP and 91% for LPD. Postoperative complication rates after LDP and LPD were 17% and 30%, and 90-day mortality rates were 0.3% and 0.4%, respectively. Shorter operation time, less blood loss, and lower incidence of pancreatic fistula were observed in institutions experienced in LDP. A higher rate of pure laparoscopic procedure and shorter operation time were noted in institutions experienced with LPD. CONCLUSION: LDPs and LPDs are performed safely in Japan, especially in experienced institutions. Our data could support the next challenges in the field of laparoscopic pancreatectomy.

Conversion surgery for initially unresectable carcinoma of the ampulla of Vater following pathological complete response to chemotherapy: a case report.

BACKGROUND: Carcinoma of the ampulla of Vater with distant metastases is regarded as unresectable. Systemic chemotherapy is basically the treatment of choice for such tumors. CASE PRESENTATION: A 68-year-old woman was referred to our hospital and diagnosed with carcinoma of the ampulla of Vater with lymph node and multiple liver metastases. She underwent systemic chemotherapy with a combination of gemcitabine and cisplatin. After 19 months of treatment, the primary tumor and liver metastases were difficult to detect on follow-up images. Shrinkage of the enlarged lymph nodes was also confirmed. Surgical resection was performed with curative intent after a multidisciplinary meeting. Pathological examination of the resected specimen showed no residual tumors. Systemic chemotherapy achieved a pathological complete response. The postoperative course was uneventful, and the patient remained free of recurrent disease at 10 months of follow-up. CONCLUSION: This case shows the possibility of conversion surgery after systemic chemotherapy for carcinoma of the ampulla of Vater.

Actual 10-Year Survival After Surgical Microwave Ablation for Hepatocellular Carcinoma: A Single-Center Experience in Japan.

BACKGROUND: Little evidence exists regarding long-term survival after microwave ablation for hepatocellular carcinoma (HCC). The aim of this study is to determine actual 10-year survival and clarify the clinicopathological features of patients surviving ≥ 10 years after surgical microwave ablation. PATIENTS AND METHODS: This retrospective study identified 459 patients who underwent surgical microwave ablation for HCC with curative intent between 2001 and 2008. We compared 100 patients who survived ≥ 10 years with 321 patients who died within 10 years. RESULTS: Median overall survival and recurrence-free survival rates were 5.5 and 2.4 years, respectively. The actual 10-year overall survival rate was 23.8%, and the actual 10-year recurrence-free survival rate was 8.1%. Multivariate analysis showed that age > 70 years [odds ratio 1.87, P = 0.029], hepatitis C virus positivity (OR 2.30, P = 0.004), Child-Pugh class B (OR 3.28, P = 0.003), and platelet count < 10 × 104 /µL (OR 1.93, P = 0.033) were independent risk factors for actual 10-year survival. During 10-year follow-up, 66% of the ≥ 10-year survivors developed recurrence, and 91% of these patients underwent further curative treatment, including hepatic resection or local ablation, for HCC recurrence. CONCLUSION: Ten-year survival after surgical microwave ablation for HCC can be expected in approximately 24% of patients, even though nearly 2/3 of our 10-year survival patients experienced recurrence. Close postoperative follow-up and further curative treatment for recurrence are important for improving long-term survival.

Hepatic resection versus operative microwave ablation for single hepatocellular carcinoma ≤5 cm: A propensity score-matched analysis.

BACKGROUND: Little evidence exists regarding the perioperative and oncologic benefits of microwave ablation for hepatocellular carcinoma. The aim of this study was to compare the efficacy of hepatic resection and operative microwave ablation (microwave coagulo-necrotic therapy) for single hepatocellular carcinoma ≤5 cm. METHODS: Between 1994 and 2015, a total of 551 patients with a single hepatocellular carcinoma ≤5 cm were treated in our institution (hepatic resection: n = 128; microwave coagulo-necrotic therapy: n = 423). We compared overall survival and recurrence-free survival between hepatic resection and microwave coagulo-necrotic therapy. Propensity score matching analysis identified 94 matched pairs of patients to compare outcomes. RESULTS: After propensity score matching, baseline variables, including liver function and tumor size, were well-balanced between the 2 groups. The 5- and 10-year overall survival rates were 76% and 47% for hepatic resection and 77% and 48% for microwave coagulo-necrotic therapy, respectively (P = .865). The 5- and 10-year recurrence-free survival rates were 55% and 41% for hepatic resection and 47% and 32% for microwave coagulo-necrotic therapy, respectively (P = .377). In the subgroup analysis, the hepatic resection group had better recurrence-free survival than the microwave coagulo-necrotic therapy group in patients with tumor size >3 cm, with 5-year recurrence-free survival rates of 56.5% and 32.4% in the hepatic resection and microwave coagulo-necrotic therapy group, respectively (P = .029). CONCLUSION: Our propensity score matching study confirmed no statistically significant differences in both overall survival and recurrence-free survival between hepatic resection and microwave coagulo-necrotic therapy for single hepatocellular carcinoma ≤5 cm; however, hepatic resection is recommended for hepatocellular carcinoma with tumor size >3 cm when patients have good liver function.

A Clinical Scoring System for Predicting Microvascular Invasion in Patients with Hepatocellular Carcinoma Within the Milan Criteria.

BACKGROUND: Microvascular invasion (MVI) is recognized as a risk factor for early recurrence of hepatocellular carcinoma (HCC) within the Milan criteria after curative treatment. METHODS: One hundred eleven consecutive patients with HCC within the Milan criteria who underwent hepatic resection were retrospectively reviewed. Independent preoperative predictors of MVI were identified, and a scoring system was developed using significant predictors. RESULTS: MVI was identified in 51 of 111 patients (46%). Multivariate analysis identified the following independent predictors of MVI: alpha-fetoprotein (AFP) of > 95 ng/mL (odds ratio [OR], 9.87; 95% confidence interval [95% CI], 2.24-56.8; P = 0.002), des-γ-carboxy prothrombin (DCP) of > 55 mAU/mL (OR, 5.50; 95% CI, 2.09-15.4; P < 0.001), tumor size of > 2.8 cm (OR, 6.10; 95% CI, 2.07-20.0; P < 0.001), and non-smooth tumor margin in the hepatobiliary phase of gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) (OR, 5.34; 95% CI, 1.84-16.9; P = 0.002). A clinical scoring system was developed using these four variables. Within a total possible score of 0 to 4, the prevalence of MVI with a score of 0, 1, 2, 3, and 4 was 4.5%, 24.0%, 45.5%, 91.7%, and 100%, respectively (P < 0.001). The area under the curve of the scoring system was 0.865 based on the receiver operating characteristic curve analysis of the prediction score. CONCLUSIONS: Our clinical scoring system, consisting of AFP, DCP, tumor size, and tumor margin in Gd-EOB-DTPA-enhanced MRI, can be valuable for predicting MVI in HCC within the Milan criteria before curative treatment.

Oncological outcomes after hepatic resection and/or surgical microwave ablation for liver metastasis from gastric cancer.

BACKGROUND: Indications and efficacy of surgical treatment for liver metastases from gastric cancer (LMGCs) remain controversial. This retrospective study was designed to clarify the benefits of surgical treatment and identify prognostic factors. METHODS: Between December 1997 and December 2015, 34 consecutive patients underwent hepatic resection and surgical microwave ablation for synchronous or metachronous LMGCs at our institution. We analyzed their cumulative overall survival (OS) and recurrence-free survival (RFS) rates and clinical parameters to identify predictors of prognosis. RESULTS: Of the 34 patients, 14 underwent hepatic resection, 13 underwent surgical microwave ablation, and 7 underwent hepatic resection combined with surgical microwave ablation. Their OS rates were 1-year: 84.4%, 3-year: 38.6%, and 5-year: 34.7%; and their RFS rates were 1-year: 38.5%, 3-year: 28.0%, and 5-year: 28.0%. OS did not significantly vary among the surgical procedures. In multivariable analysis, positive of both CEA and CA19-9 were independent predictors of poor survival (hazard ratio [HR] 4.51; P = 0.049) and early recurrence (HR 5.70; P = 0.047). CONCLUSIONS: Both hepatic resection and surgical microwave ablation for LMGCs are effective and can improve survival in selected patients.

Prognosis of Hepatocellular Carcinoma Patients Who Achieved Long-Term Recurrence-Free Survival After Curative Therapy: Impact of the ALBI Grade.

BACKGROUND/AIMS: Some patients experience very late recurrence of HCC more than 5 years after initial therapy. We aimed to clarify the predictive factors for very late recurrence of HCC in such cases. METHODS: Among 807 HCC patients undergoing surgical resection or ablative therapy with curative intent, the patients who survived for 5 years without any recurrence were reviewed. The prognosis and possible predictive factors for late recurrence were analyzed retrospectively. RESULTS: A total of 184 patients survived for more than 5 years without recurrence. Among them, 61 patients experienced recurrence, at a median of 6 years after initial therapy. In univariate analysis, the pre-treatment aspartate aminotransferase, alanine aminotransferase, Child-Pugh class, and ALBI grade were not related to recurrence, but those at 5 years after treatment were significantly related to recurrence. By multivariate analysis, an ALBI grade of 2-3 at 5 years was an independent risk factor for recurrence (P < 0.0001). Moreover, variation of the ALBI grade over the 5 years after the initial treatment was significantly related to recurrence-free survival. CONCLUSIONS: The ALBI grade is an effective index of the variation in liver function after curative therapy and may be a useful prognostic factor for the long-term recurrence-free survival of HCC patients.
