Hepatocellular carcinoma (HCC) is one of the most prevalent malignant tumors worldwide. Liver transplantation (LT) is known as a curative and therapeutic modality. However, the survival rates of recipients after LT are still not good enough because of tumor recurrence. To improve the survival rates of recipients after LT, identifying predictive factors for prognosis after LT and establishing a model assessing prognosis are very important to HCC patients. There has recently been a lot of clinical and basic research on recurrence and prognosis after LT. Progress has been made, especially in selection criteria for LT recipients and risk factors for predicting prognosis after LT. Hangzhou criteria, in line with China's high current incidence rate of primary liver, are first proposed by Chinese scholars of LT, and are accepted world-wide, and make an important contribution to the development of LT.

Background: Decision-making concerning the treatment of choroid plexus tumor (CPT) in pediatric patients remains a topic of considerable debate. The aim of this work was to describe clinical features and prognostic risk factors of CPT in the pediatric population and to provide theoretical opinions regarding clinical decisions for CPT. Methods: The data of 96 patients with CPT and younger than 14 years were retrospectively analyzed. Clinical characteristics such as pathological type of CPTs, rate and severity of hydrocephalus, treatment and outcome, and recurrence were investigated. For categorical variables, the Pearson's Chi-square test was performed. The Mann-Whitney U-test was used for comparisons between nonnormally distributed parameters. Log-rank test was used for progression-free survival (PFS). Results: The study included 70 choroid plexus papilloma (CPP) cases, 17 atypical choroid plexus papilloma (aCPP) cases, and 9 choroid plexus carcinoma (CPC) cases. Compared with patients with CPP or aCPP, patients with CPC had a shorter disease course (median: CPP, 4 months; aCPP, 2 months; CPC, 1 month; H: 23.5, P < 0.001), higher rate of acute hydrocephalus (CPP, 27.1%; aCPP, 52.9%; CPC, 77.8%; χ = 10.9, P < 0.05), and lower incidence of cure rate (CPP, 85.7%; aCPP, 70.5%; CPC, 33.3%; χ = 13.5, P < 0.05). The severity of hydrocephalus with tumor in the lateral or third ventricle was significantly higher than that with tumors in the fourth ventricle (severe hydrocephalus: lateral ventricle, 51.7%; third ventricle, 47.0%; fourth ventricle, 11.1%; χ = 26.0, P < 0.001). Patients with gross total surgical resection had no better PFS than those with partial resection because of the use of adjuvant therapy in the latter (χ = 4.0, P > 0.05). Patients with CPC experienced shorter time for recurrence than those with CPP or aCPP (χ = 40.1, P < 0.0001). Conclusions Our results indicated that CPP in the fourth ventricle could trigger serious clinical symptoms at an early stage, requiring early intervention. Adjuvant treatment might be necessary for patients with partially resected CPP, aCPP, and CPC to achieve a favorable outcome.

OBJECTIVETo examine the association of preoperative carcinoembryonic antigen (CEA) level with the efficacy of neoadjuvant radiochemotherapy and postoperative metastasis and relapse in patients with rectal cancer.

METHODSBetween January 2011 and January 2014, 325 patients with local advanced rectal cancer underwent preoperative radiochemotherapy and radical operation in Department of Colorectal Cancer Surgery, Beijing University Cancer Hospital, including 194 males and 131 females. According to preoperative MRI, all the patients suffered from clinical T3-4 tumors or positive lymph nodes. Their Zubrod-ECOG-WHO score was 0-1. These patients received preoperative intensity modulated radiotherapy which consisted of 50.6 Gy in 22 fractions (IMRT GTV 50.6 Gy/CTV 41.8 Gy/22 f) with capecitabine(825 mg/m, twice per day) as radiosensitizer. According to the preoperative serum CEA level, patients were divided into high group (125 cases) and normal group (200 cases). In high group, serum CEA level decreased into normal range in 60 patients (high-normal group) after radiochemotherapy, while it was still in high level in other 65 patients (high-high group). The differences in sensitivity to radiochemotherapy and 3-year disease free survival (DFS) of these patients were both evaluated.

RESULTSIn high group and normal group, the complete response rates were 18.4% (23/125) and 17.5% (35/200) (χ=0.319, P=0.660); the percentages of tumor regression grade(TRG) 0-1 patients were 68.0%(85/125) and 67.5%(135/200)(χ=0.009, P=0.925); the T downstage rates were 63.2%(79/125) and 70.0%(140/200)(χ=1.266, P=0.274), respectively, whose differences were all not significant. The 3-year DFS rate in high group was 62.4%, which was significantly lower than 93.5% in normal group (χ=53.147, P=0.000). There were 65 patients in high-high group, accounting for 52% (65/125) of high group. Among these 65 patients, 44(67.7%) presented recurrence and metastasis within 3 years and the 3-year DFS was 32.3%, which was much lower than 95.0% of 60 patients in high-normal group(χ=182.085, P=0.000).

CONCLUSIONSPreoperative serum CEA level may not be used to predict tumor response of rectal cancer patients who receive preoperative radiochemotherapy. However, the prognosis of patients with high CEA level is worse. Recurrence and metastasis are more likely to occur in patients with high CEA level after radiochemotherapy.

OBJECTIVETo investigate the safety and efficacy of organ preservation surgery or "watch and wait" strategy for rectal cancer patients who are evaluated as clinical complete response(cCR) or near-cCR following neoadjuvant chemoradiotherapy (nCRT).

METHODFrom March 2011 to June 2016, 35 patients with mid-low rectal cancers who were diagnosed as cCR or near-cCR following nCRT underwent organ preservation surgery with local excision or surveillance following "watch and wait" strategy in the Peking University Cancer Hospital. All the patients received re-evaluation and re-staging 6-12 weeks after the completion of nCRT, according to Habr-Gama and MSKCC criteria for the diagnosis of cCR or near-cCR. The near-cCR patients who received local excision and were pathologically diagnosed as T0Nx were also regarded as cCR. The end-points of this study included organ-preservation rate (OPR), sphincter-preservation rate (SPR), non-re-growth disease-free survival (NR-DFS), stoma-free survival, cancer-specific survival (CSS) and overall survival(OS). Kaplan-Meier curve was used to estimate the survival data at 3 years.

RESULTSA total of 35 cases were analyzed including 24 males (68.6%) and 11 females (31.4%). The median age was 60 (range 37-79) years and the median distance from tumor to anal edge was 4(2-8) cm. Thirty-three patients received 50.6 Gy/22f IMRT with capecitabine and two patients received 50 Gy/25f RT with capecitabine. The cCR and near-cCR rates were 74.3%(26/35) and 25.7%(9/35) respectively. Excision biopsy was performed in 4 near-cCR cases to confirm the diagnosis of cCR. The non-re-growth DFS rate was 14.3%(5/35) and the median time of tumor re-growth was 6.7 (4.7-37.4) months. In five patients with tumor re-growth, four were salvaged by radical rectal resections and one received local excision. The distant metastasis rate was 5.7%(2/35), one patient presented resectable liver metastasis and received radical resection, another patient presented multiple bone metastases and was still alive. The median follow-up time was 43.7(6.1-71.4) months. At three years, the organ-preservation rate was 88.6%(31/35), the sphincter-preservation rate was 97.1% (34/35). No local recurrence was observed in five patients who received salvage surgery. The non-re-growth DFS was 94.0%. Three patients died of non-rectal cancer related events. The cancer-specific survival was 100%, the overall survival was 92.7% and the stoma-free survival rate was 90.0%.

CONCLUSIONSOrgan preservation surgery or "watch and wait" strategy for cCR or near-cCR patients is feasible and achieves good outcomes. This strategy can be an alternative to standard care, improve patient's quality of life and facilitate tailored treatment for mid-low rectal cancer following nCRT, however, it should be cautiously applied in near-cCR patients before local excision biopsy.

OBJECTIVETo systematically assess the safety and efficacy of hand-assisted laparoscopic distal gastrectomy (HALG) versus open distal gastrectomy (ODG) for gastric cancer.

METHODSChinese or English literature regarding comparison of HALG and ODG were collected by searching in databases (such as PubMed, Cochrane Library, CNKI, Wanfang database) between January 1996 and September 2016. The data of operative time, incision length, blood loss, number of harvested lymph nodes, time to flatus, hospital stay, postoperative complication morbidity and long-term outcomes were compared between the two procedures. Then funnel plot was used to evaluate publication bias and sensitivity analysis was used to evaluate the stability of the results. All these data analyses were performed using the Meta for or Meta package of R version 3.3.1.

RESULTSA total of 7 studies with 835 patients (323 cases in HALG group and 512 cases in ODG group) were included. Compared with ODG, HALG had a longer operative time (WMD=28.93 minutes, 95%CI=9.59 to 48.28, Z=2.93, P=0.000), a shorter incision length (WMD=-10.31 cm, 95%CI=-14.01 to -6.62, Z=-5.47, P=0.000), less blood loss (WMD=-140.08 ml, 95%CI=-215.07 to -65.09, Z=-3.66, P=0.000), faster gastrointestinal recovery (WMD=-1.23 days, 95%CI=-1.89 to -0.56, Z=-3.62, P=0.000), shorter postoperative hospital stay (WMD=-3.24 days, 95%CI=-5.47 to -1.02, Z=-2.85, P=0.000). In subgroup analysis, 3 studies published before 2013 vs. 4 studies published afterwards, the number of harvested lymph nodes (WMD=-0.78, 95%CI=-2.05 to 0.50, Z=-1.19, P=0.235) and postoperative complication morbidity (RR=1.02, 95%CI=0.43 to 2.44, Z=0.05, P=0.961) did not differ significantly between two groups. Compared with ODG, the RR(95%CI) of ileus of HALG was 0.43 (0.07 to 2.82), but the difference was not statistically significant (P=0.383). One study reported the 5-year overall survival rates of HALG and ODG were 81.0% vs 67.5%, and the tumor recurrence rates were 7.1% vs 22%, respectively, but the differences were not statistically significant(all P>0.05). Sensitivity analysis showed that the above results were stable. The funnel plots of the lymph nodes and postoperative complication morbidity did not present significant publication bias.

CONCLUSIONSHALG has the advantages of minimal invasiveness such as shorter incision length and quicker recovery. Furthermore, the short-term efficacy of HALG is similar to conventional open surgery. However, the long-term efficacy is lack of support from multicenter long-term follow-up results.

BACKGROUNDThe absolute lymphocyte counts (ALCs) have been reported as one of worse prognostic factors for hepatocellular carcinoma (HCC) patient after liver transplantation. The aim of this study was to assess the influence of ALCs on the outcomes of patients with hepatitis B virus (HBV)-related HCC within the Milan criteria following liver resection.

METHODSData of patients with HCC within the Milan criteria who received liver resection between January 2007 and June 2013 were reviewed, and perioperative ALCs were carefully monitored. All potential risk factors were statistically analyzed by uni- and multi-variate analyses. The receiver operating characteristic (ROC) curve was used to determine the optimal ALCs cut-off value to predict HCC recurrence after liver resection.

RESULTSA total of 221 patients were enrolled in the current study. During the follow-up period, 106 patients experienced recurrence, and 38 patients died. Multivariate analysis suggested microvascular invasion (MVI), a tumor grade ≥2, and a low postoperative ALCs in the 1st postoperative month increased the incidence of postoperative recurrence, besides, MVI, intraoperative transfusion, and a low postoperative ALCs in the 1st postoperative month were associated with poor overall survival (OS). An ROC analysis showed that a cut-off value of 1.5 × 109/L for ALCs in the 1st postoperative month predicted postoperative recurrence. The 5-year recurrence-free survival (RFS) and OS rates of patients with low postoperative ALCs were 34.5% and 64.8%, respectively, which were significantly lower than those of patients with high postoperative ALC (58.5% for RFS and 86.5% for OS).

CONCLUSIONLow ALCs in the 1st postoperative month may be associated with high recurrence incidence and poor OS for patients with HBV-related HCC within the Milan criteria after liver resection.

OBJECTIVE: To evaluate the recurrence rates and patterns of failure in patients with stage I endometrial carcinoma after surgical staging without adjuvant therapy. METHODS: Medical records of 229 patients with stage I endometrial carcinoma, treated with surgery alone between 2002 and 2010 at Siriraj Hospital were retrospectively reviewed. The primary objective of this study was recurrence rates. The secondary objectives were patterns of failure, disease-free survival, overall survival, and prognostic factors related to outcomes. RESULTS: During median follow-up time of 53.3 months, 11 recurrences (4.8%) occurred with a median time to recurrence of 21.2 months (range, 7.7 to 77.8 months). Vaginal recurrence was the most common pattern of failure (8/11 patients, 72.7%). Other recurrences were pelvic, abdominal and multiple metastases. Factors that appeared to be prognostic factors on univariate analyses were age and having high intermediate risk (HIR) (Gynecologic Oncology Group [GOG] 99 criteria), none of which showed significance in multivariate analysis. The recurrence rates were higher in the patients with HIR criteria (22.2% vs. 4.1%, p=0.013) or patients with stage IB, grade 2 endometrioid carcinoma (9.4% vs. 4.3%, p=0.199). Five-year disease-free survival and 5-year overall survival were 93.9% (95% CI, 89.9 to 5.86) and 99.5% (95% CI, 97.0 to 99.9), respectively. CONCLUSION: The patients with low risk stage I endometrial carcinoma had excellent outcomes with surgery alone. Our study showed that no single factor was demonstrated to be an independent predictor for recurrence.

BACKGROUND/AIMS: Radiofrequency ablation (RFA) is one of the most frequently applied curative treatments in patients with a single small hepatocellular carcinoma (HCC). However, the clinical significance of and risk factors for early massive recurrence after RFA—a dreadful event limiting further curative treatment—have not been fully evaluated. METHODS: In total, 438 patients with a single HCC of size ≤3 cm who underwent percutaneous RFA as an initial treatment between 2006 and 2009 were included. Baseline patient characteristics, overall survival, predictive factors, and recurrence after RFA were evaluated. In addition, the incidence, impact on survival, and predictive factors of early massive recurrence, and initial recurrence beyond the Milan criteria within 2 years were also investigated. RESULTS: During the median follow-up of 68.4 months, recurrent HCC was confirmed in 302 (68.9%) patients, with early massive recurrence in 27 patients (6.2%). The 1-, 3-, and 5-year overall survival rates were 95.4%, 84.7%, and 81.8%, respectively, in patients with no recurrence, 99.6%, 86.4%, and 70.1% in patients with recurrence within the Milan criteria or late recurrence, and 92.6%, 46.5%, and 0.05% in patients with early massive recurrence. Multivariable analysis identified older age, Child-Pugh score B or C, and early massive recurrence as predictive of poor overall survival. A tumor size of ≥2 cm and tumor location adjacent to the colon were independent risk factors predictive of early massive recurrence. CONCLUSIONS: Early massive recurrence is independently predictive of poor overall survival after RFA in patients with a single small HCC. Tumors sized ≥2 cm and located adjacent to the colon appear to be independent risk factors for early massive recurrence.

OBJECTIVETo explore the feasibility, safety and efficacy of intraoperative regional infusion chemotherapy by celiac trunk in advanced gastric cancer patients.

METHODSOne hundred and twenty-six patients with advanced gastric cancer(stageII(-III() were screened from database of Gastrointestinal Surgery Department of Taizhou People's Hospital between January 2008 and December 2010 who underwent R0 resection and D2 lymphadenectomy, received postoperative chemotherapy(XELOX or FOLFOX), and had complete follow-up data. They were divided into infusion chemotherapy group (65 cases) and control group (61 cases) according to regional infusion chemotherapy or not (fluorine 1 000 mg and cisplatin 60 mg). The side effects of chemotherapy, parameters related to the operation, long-term survival and relapse rate were compared between the two groups.

RESULTSThe baseline data between the two groups were comparable(all P>0.05). Postoperative III( and IIII( adverse reaction of chemotherapy was not significantly different between the two groups (P>0.05). The time of postoperative intestinal function recovery [(67.9±14.8) hours vs. (68.9±15.0) hours, t=-0.380, P=0.705), volume of postoperative 1-week drainage [(66.1±17.1) ml vs.(61.9±18.2) ml, t=1.478, P=0.142], recent morbidity of complications[55.4%(36/65) vs. 49.2%(30/61), χ=0.256, P=0.613], and the long-term morbidity of complications [16.9% (11/65) vs. 14.8% (9/61), χ=0.111, P=0.739] were all not significantly different between the two groups. The 3-year survival rate and 3-year relapse-free survival rate in infusion chemotherapy group were significantly higher than those in control group(58.4% vs. 37.7%, χ=5.382, P=0.020; 58.4% vs. 34.4%, χ=6.636, P=0.010).

CONCLUSIONRegional infusion chemotherapy by celiac trunk during operation for advanced gastric cancer patients is safe and feasible, and can reduce the risk of local recurrence and improve survival rate.

PURPOSE: The aim of this study was to evaluate the efficacy of re-irradiation in patients with recurrent gliomas and to identify subgroups for whom re-irradiation for recurrent gliomas is most beneficial. MATERIALS AND METHODS: We retrospectively reviewed 36 patients with recurrent or progressive gliomas who received re-irradiation between January 1996 and December 2011. Re-irradiation was offered to recurrent glioma patients with good performance or at least 6 months had passed after initial radiotherapy (RT), with few exceptions. RESULTS: Median doses of re-irradiation and initial RT were 45.0 Gy and 59.4 Gy, respectively. The median time interval between initial RT and re-irradiation was 30.5 months. Median overall survival (OS) and the 12-month OS rate were 11 months and 41.7%, respectively. In univariate analysis, Karnofsky performance status (KPS) ≥70 (p<0.001), re-irradiation dose ≥45 Gy (p=0.040), and longer time interval between initial RT and re-irradiation (p=0.040) were associated with improved OS. In multivariate analysis, KPS (p=0.030) and length of time interval between initial RT and re-irradiation (p=0.048) were important predictors of OS. A radiographically suspected mixture of radiation necrosis and progression after re-irradiation was seen in 5 patients. CONCLUSION: Re-irradiation in conjunction with surgery could be a salvage treatment for selected recurrent glioma patients with good performance status and recurrence over a long time.
