    ABSTRACT: To investigate the clinical features and prognostic factors of advanced hepatocellular carcinoma (HCC) patients presenting with lung metastasis at initial diagnosis. Between 2001 and 2010, we recruited 76 consecutive HCC patients initially presenting with lung metastasis, without co-existing metastasis from other sites. These patients were divided into three groups: untreated group (n = 22), single treatment group (n = 19), and combined treatment group (n = 35). Metastasis of bilateral lung lobes was common and noted in 35 patients (46.1%), and most of patients (59/76, 77.6%) presented with multiple lung metastatic nodules. Nineteen patients (25.0%) received single-method treatment, including hepatectomy in 4, transcatheter arterial chemoembolization in 6, radiotherapy in 5, and oral sorafenib in 4. Thirty-five patients (46.1%) received combined treatment modalities. The overall median survival of the all patients was 8.7 ± 0.6 mo; 4.1 ± 0.3, 6.3 ± 2.5 and 18.6 ± 3.9 mo, respectively in the untreated group, single treatment group and combined treatment group, respectively, with a significant difference (log-rank test, P < 0.001). Multivariate analysis revealed that Child-Pugh score, the absence or presence of portal vein tumor thrombus, and treatment modality were three independent prognostic factors affecting survival of patients with advanced HCC and concomitant lung metastasis. Combined treatment modalities tend to result in a better survival as compared with the conservative treatment or single treatment modality for HCC patients initially presenting with lung metastasis.

    ABSTRACT: The BCLC staging classification has been widely endorsed to predict the prognosis of patients with HCC. However, its validity as a means of therapeutic instructions needs to be challenged. This study aimed to evaluate perioperative and long-term outcomes of surgical resection in patients with advanced hepatocellular carcinoma (HCC) according to the Barcelona Clinic Liver Cancer (BCLC) staging. This study used a prospectively maintained database consisting of a consecutive series of 511 Chinese patients with advanced HCC who underwent surgical resection in a hepatobiliary surgical center from 2001 to 2007. Mortality, morbidity, long-term overall survival (OS) and disease-free survival (DFS) were evaluated. Hospital mortality was 2.3%, and overall morbidity was 31.3%. After a median follow-up period of 27.8 months (range, 0-112 months), the 1-, 3- and 5-year OS rate was 69.9, 41.2 and 30.5%, and the 1-, 3- and 5-year DFS rate was 48.2, 30.3 and 24.0%, respectively. The 1-, 3- and 5-year OS and DFS rates were significantly poorer in patients with vascular invasion and/or extrahepatic spread than those in patients without (both P < 0.001), and also poorer in patients with biliary invasion than those in patients without (both P < 0.05). Surgical resection could be considered in part of patients with advanced HCC (BCLC stage C), with low mortality, acceptable morbidity and favorable survival benefits. These results imply that BCLC recommendations for treatment schedules of advanced HCC need to be re-evaluated.

    ABSTRACT: To assess the benefits and limits of surgery for primary hepatic lymphoma (PHL), and probability of survival after postoperative chemotherapy. A retrospective analysis was undertaken to determine the results of surgical treatment of PHL over the past 8 years. Only nine patients underwent such treatment. The detailed data of diagnosis, treatment, and prognosis were carefully studied. All patients were mistaken as having α-fetoprotein-negative hepatic cancer before pathological diagnosis. The mean delay time between initial symptoms and final diagnosis was 26.8 d (range: 14-47 d). Hepatitis B virus infection was noted in 33.3% of these patients. Most of the lesions were found to be restricted to a solitary hepatic mass. The surgical procedure performed was left hepatectomy in five cases, including left lateral segmentectomy in three. Right hepatectomy was performed in three cases and combined procedures in one. One patient died on the eighth day after surgery, secondary to hepatic insufficiency. The cumulative 6-mo, 1-year, and 2-year survival rates after hepatic surgery were, respectively, 85.7%, 71.4%, and 47.6%. One patient survived for > 5 years after surgery without any signs of recurrence until latest follow-up, who received routine postoperative chemotherapy every month for 2 years and then regular follow-up. By univariate analysis, postoperative chemotherapy was a significant prognostic factor that influenced survival (P = 0.006). PHL is a rare entity that is often misdiagnosed, and has a potential association with chronic hepatitis B infection. The prognosis is variable, with good response to early surgery combined with postoperative chemotherapy in strictly selected patients.
