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.

BACKGROUNDThe liver is the most common site for colorectal cancer (CRC) metastases. Their removal is a critical and challenging aspect of CRC treatment. We investigated the prognosis and risk factors of patients with CRC and liver metastases (CRCLM) who underwent simultaneous resections for both lesions.

METHODSFrom January 2009 to August 2016, 102 patients with CRCLM received simultaneous resections of CRCLM at our hospital. We retrospectively analyzed their clinical data and analyzed their outcomes. Overall survival (OS) and disease-free survival (DFS) were examined by Kaplan-Meier and log-rank methods.

RESULTSMedian follow-up time was 22.7 months; no perioperative death or serious complications were observed. Median OS was 55.5 months; postoperative OS rates were 1-year: 93.8%, 3-year: 60.7%, and 5-year: 46.4%. Median DFS was 9.0 months; postoperative DFS rates were 1-year: 43.1%, 3-year: 23.0%, and 5-year 21.1%. Independent risk factors found in multivariate analysis included carcinoembryonic antigen ≥100 ng/ml, no adjuvant chemotherapy, tumor thrombus in liver metastases, and bilobar liver metastases for OS; age ≥60 years, no adjuvant chemotherapy, multiple metastases, and largest diameter ≥3 cm for DFS.

CONCLUSIONSSimultaneous surgical resection is a safe and effective treatment for patients with synchronous CRCLM. The main prognostic factors are pathological characteristics of liver metastases and whether standard adjuvant chemotherapy is performed.

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.

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.

BACKGROUND/AIMS: Several studies have suggested that surgical resection (SR) can provide a survival benefit over transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) at the intermediate stage according to the Barcelona Clinic Liver Cancer (BCLC) staging system. However, the criteria for SR remain to be determined. This study compared the long-term outcome of intermediate-stage HCC patients treated by either TACE or SR as a primary treatment modality, with the aim of identifying the patient subgroup that gained a survival benefit by either modality. METHODS: In total, 277 BCLC intermediate-stage HCC patients treated by either TACE (N=225) or SR (N=52) were analyzed. RESULTS: The overall median survival time was significantly better for SR than TACE (61 vs. 30 months, P=0.002). Decision-tree analysis divided patients into seven nodes based on tumor size and number, serum alpha-fetoprotein (AFP) level, and Child-Pugh score, and these were then simplified into four subgroups (B1-B4) based on similarities in the overall hazard rate. SR provided a significant survival benefit in subgroup B2, characterized by ‘oligo' (2-4) nodules of intermediate size (5-10 cm) when the AFP levels was <400 ng/ml, or ‘oligo' (2-4) nodules of small to intermediate size (<10 cm) plus a Child-Pugh score of 5 when the AFP level was ≥400 ng/mL (median survival 73 vs. 28 months for SR vs. TACE respectively; P=0.014). The survival rate did not differ significantly between SR and TACE in the other subgroups (B1 and B3). CONCLUSIONS: SR provided a survival benefit over TACE in intermediate-stage HCC, especially for patients meeting certain criteria. Re-establishing the criteria for optimal treatment modalities in this stage of HCC is needed to improve survival rates.

BACKGROUNDControversial results about the therapeutic value of radiofrequency ablation (RFA) and liver resection (LR) in the treatment of colorectal cancer liver metastasis (CRCLM) have been reported. Thus, we performed the present meta-analysis to summarize the related clinical evidences.

METHODSA systematic literature search was conducted using PubMed (Medline), EMBASE, Cochrane Library, and Web of Science, for all years up to April 2016. Pooled analyses of the overall survival (OS), progression-free survival (PFS), and morbidity rates were performed.

RESULTSA total of 14 studies were finally enrolled in the meta-analysis. Patients treated by LR gained a longer OS and PFS than those of patients treated by RFA. Patients in the RFA group had lower morbidity rates than those of patients in the LR group. Publication bias analysis revealed that there was no significant publication bias in the meta-analysis.

CONCLUSIONSPatients with CRCLM gained much more survival benefits from LR than that from RFA. RFA rendered lower rates of morbidities. More well-designed randomized controlled trails comparing the therapeutic value of LR and RFA are warranted.

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.

BACKGROUND: Metastatic pathological fractures of the spine are a major problem for cancer patients; however, there is no consensus on treatment strategy. The purpose of this study was to evaluate various treatment options by analyzing their patterns for metastatic pathological fractures of the spine. METHODS: In this study, 54 patients (male:female = 36:18) who were diagnosed with metastatic pathological fractures of spine were recruited. Demographic data, origin of cancer, type of treatment, and results were obtained from electronic medical records. Treatment options were divided into radiotherapy (RT), vertebroplasty (VP) or kyphoplasty (KP), operation (OP), and other treatments. Treatment results were defined as aggravation, no response, fair response, good response, and unknown. The survival time after detection of pathologic fractures was analyzed with the Kaplan-Meier method. RESULTS: The mean age of the patients was 62.3 years. Hepatocellular carcinoma was the most common cancer of primary origin (n = 9), followed by multiple myeloma (n = 8). RT was the most common primary choice of treatment (n = 29, 53.7%), followed by OP (n = 13, 24.1%), and VP or KP (n = 10, 18.5%). Only 13 of 29 RT cases and 7 of 13 OP cases demonstrated a fair or good response. The mean survival time following detection of pathological spinal fractures was 11.1 months for 29 patients, who died during the study period. CONCLUSIONS: RT was the most common primary choice of treatment for metastatic pathological fractures of the spine. However, the response rate was suboptimal. Although OP should be considered for the relief of mechanical back pain or neurologic symptoms, care should be taken in determining the surgical indication. VP or KP could be considered for short-term control of localized pain, although the number of cases was too small to confirm the conclusion. It is difficult to determine the superiority of the treatment modalities, hence, a common guideline for the diagnosis and treatment of metastatic pathological fractures of the spine is required.

OBJECTIVETo investigate the differences between clinicopathological features and prognosis of alpha-fetoprotein (AFP) negative (AFP < 20 ng/ml) and positive (AFP ≥ 20 ng/ml) hepatocellular carcinoma (HCC) patients.

METHODSClinicopathological data of 142 AFP-negative and 109 AFP-positive HCC patients who underwent RO radical hepatectomy in the Cancer Hospital of Chinese Academy of Medical Sciences between January 2006 and December 2011 were retrospectively reviewed and analyzed in this study.

RESULTSCompared with the AFP-negative patients, a higher female to male sex ratio, the later Barcelona Clinic Liver Cancer ( BCLC) stage, more liver capsule invasion and poorer Edmondson-Steiner grade were in the AFP-positive cases (P < 0.05 for all). Furthermore, the 1-, 3-, and 5- year overall survival rates were 94.4%, 82.4% and 61.0% in the AFP-negative group and 87.2%, 61.1% and 40.2%, respectively, in the AFP-positive group (P < 0.001). The multivariate analysis with Cox's proportional hazards model showed that AFP status, tumor size and Edmondson-Steiner grade are independent risk factors for survival of all the patients (P < 0.05) , and large tumor and Edmondson-Steiner grades III/IV are independent risk factors for worse survival in AFP-negative patients (P < 0.05). However, large tumor diameter was proved to be an independent risk factor leading to poor prognosis of AFP-positive cases (P < 0.05).

CONCLUSIONHigh levels of AFP indicate that the tumors are more malignant and with unfavorable prognosis.
