ABSTRACT: To investigate the prognostic factors of hepatocellular carcinoma.
The purpose of this study was to retrospectively analyze the surgical outcomes of hepatocellular carcinoma (HCC) in 832 patients who underwent hepatic resection between February 2002 and June 2010 in the Cancer Hospital of Chinese Academy of Medical Sciences. Post-resection prognostic factors were assessed using a univariate Kaplan-Meier analysis and a multivariate Cox proportional hazards model.
The overall 1-, 3- and 5-year survival rates were 92.0%, 70.2% and 53.6%, respectively. The disease free survival rates (DFS) were 90.2%, 61.5% and 40.5%, respectively. The univariate analysis showed that a better prognosis for overall survival (OS) was associated with asymptomatic presentation, small tumor, single lesion, high-grade histological differentiation, no vascular tumor embolus, negative serum alpha-fetoprotein (AFP), negative serum alkaline phosphatase (ALP), Child-Pugh class A, no ascites, no/mild cirrhosis, new surgical techniques, no blood transfusion, no regional lymph node metastasis, no major vascular invasion, and no extra-hepatic invasion. The multivariate analysis showed that asymptomatic presentation, small tumor, single lesion, no tumor embolus, negative serum alpha-fetoprotein (AFP), no regional lymph node metastasis, no major vascular invasion, no extra-hepatic invasion, no/mild cirrhosis, and surgical techniques are independent factors for a longer overall survival.
The prognosis of HCC after resection is influenced by a number of factors. Therefore, regularly screening and early diagnosis, applying surgical techniques to minimize the liver injury, and preventing the aggravation of cirrhosis are important measures to improve the overall survival of HCC patients. For those patients with high risk factors of recurrence, routine follow-up is one of the best methods to be recommended.

ABSTRACT: ObjectiveTo discuss the effects of clinico-pathological features on lymph node metastasis (LNM) in undifferentiated EGC (early gastric
cancer), as well as identify the appropriate medical management.
MethodsFrom January 1999 to June 2011, 352 patients were treated for undifferentiated EGC in our hospital. All patients had undergone
gastrectomy with regional lymphadenectomy. We used univariate and multivariate analyses to determine the features associated
with lymph node metastasis in patients with undifferentiated EGC.
ResultsSignet ring cell carcinoma (SRC) was more common in patients with undifferentiated EGC than other undifferentiated carcinoma
(UDC). SRC had a tendency to be confined to the mucosa, with a smaller size than other UDC. The incidence of LNM for SRC was
lower than that for other UDC. Multivariate analysis showed that LNM was associated with the sex, tumor size, depth of invasion,
lymphovascular invasion, and histological type.
ConclusionComplete endoscopic resection is suitable for SRCtype intramucosal EGC, which is less than 2 cm in diameter without lymphovascular
invasion in the postoperative histological examination.

ABSTRACT: To explore and improve the diagnosis and treatment of benign hyperplasia tumor-like hepatic lesion.
The clinical data of 72 patients who had undergone hepatic resection for benign non-cystic hepatic lesions between January 1987 and December 2010 were analyzed retrospectively. There were 46 male and 26 female patients. The median age was 49 years (ranging 15 to 72 years), and diagnosis were confirmed by postoperative pathological examination. Thirty-four cases had symptoms, such as abdominal discomfort in right upper quadrant, fever, fatigue. All the cases had undergone hepatic resection; totally 78 lesions were removed. The surgical procedure including hepatic lobectomy for 13 cases, hepatic segmentectomy for 19 cases and non-anatomy resection for 39 cases.
The finally diagnosis included focal nodular hyperplasia in 47 cases, adenomatous hyperplasia in 3 cases, hepatic dysplastic nodule in 3 cases, inflammatory pseudotumor in 3 cases, hepatic granuloma in 4 cases, nodular cirrhosis in 3 cases, hepatitis nodule in 6 cases, nodular regenerative hyperplasia in 1 case, lymphoid hyperplasia in 1 case. The postoperative complication rate was low (19.4%, 14/72). The follow-up period was 6 to 96 months. There was no mortality caused by lesion. One patient developed recurrence after 3 years.
It is suggested that symptomatic lesions, lesions when malignancy cannot be excluded, and lesions which have canceration tendency, just like adenomatous hyperplasia, dysplastic nodule, and nodular cirrhosis regenerative hyperplasia need surgical resection. Operation is not necessary for other nodular hyperplasia lesions if the diagnoses are identified.

ABSTRACT: To investigate the influence of combined hepatectomy with splenectomy on safety of operation for hepatocellular carcinoma patients complied with cirrhosis and hypersplenism and the best peri-operative treatment of these patients.
Clinical data of 177 hepatocellular carcinoma patients complied with cirrhosis and hypersplenism admitted from January 1999 to December 2009 were analyzed retrospectively. Among which, 71 patients received concomitant splenectomy with hepatectomy (splenectomy group), 106 patients only receive a hepatectomy (non-splenectomy group). The safety of operation, complications, liver function and WBC and PLT counts were compared between the two groups.
There was no significant difference of general conditions, counts of WBC and PLT between the two groups before operation. The counts of PLT at 1, 10, 30 day after operation were (88.4 ± 23.6) × 10⁹/L, (345.3 ± 98.2) × 10⁹/L and (210.8 ± 92.2) × 10⁹/L respectively in splenectomy group, which were significantly higher than that of non-splenectomy group (P < 0.05). The operation time of splenectomy group was (216 ± 105) min, which was longer than that of non splenectomy group (P < 0.05), but the blood loss and transfusion rate had not significantly difference between the two groups. The complication rates of splenectomy group and non-splenectomy group were 11.3% and 6.6% respectively, there was no significant difference between the two groups.
Combined hepatectomy with splenectomy will be safe for hepatocellular carcinoma patients complied with cirrhosis and hypersplenism as if the operative indication and increase the ability of peri-operative treatment are strictly obeyed.

ABSTRACT: To investigate the effectiveness of anatomic method of separation in hepatectomy methods of decreasing postoperative complication and mortality for liver cancer patients.
The clinical data of 398 patients with liver malignant tumors, admitted in our hospital during 2001 to 2007, were retrospectively analyzed. The anatomic method group (group A) included 243 contiguous patients of liver cancer who received hepatectomy by anatomical method of separation, while the traditional method group (group B) included 155 patients of liver cancer who received hepatectomy by traditional method of separation during the same period. Blood loss and transfusion during operation, postoperative liver function, complication and mortality of operation, and postoperative hospital stay were compared between these two groups.
In group A, the tumor diameters ranged (6.02 +/- 3.24) cm, the operative blood loss was (445 +/- 240) ml, and 52 patients (24.3%) underwent blood transfusion [range: (520 +/- 280) ml]. No mortality and intraabdominal hemorrhage, liver function failure, or other severe complications were noted. Only 12 patients (4.9%) suffered mild complications. The postoperative hospital stay was (13.4 +/- 4.9) days. In group B, the tumor diameters ranged (5.84 +/- 2.93 cm, the operative blood loss was (1200 +/- 320) ml, and 53 patients (34.2%) underwent transfusion [range: (1400 +/- 623) ml]. Five patients (3.23%) died within 30 days after operation. The total complication morbidity was 16.1% (25/155). Five patients suffered intraabdominal hemorrhage and 5 experienced liver function failure. Postoperative hospital stay was (18.9 +/- 10.3) days. The volume of blood loss and transfusion in group A were significantly less than in group B (P < 0.05). Mortality, severe complications, and total complication morbidity were significantly lower in group A than in group B (P < 0.05, P < 0.01). The postoperative stay was also significantly shorter in group A than in group B (P < 0.05).
Anatomical method of separation is an effective method of hepatectomy with relatively low complication and mortality.

ABSTRACT: To explore the diagnosis, treatment, and prognostic factors of liver sarcoma.
The clinical data of 16 liver sarcoma patients, 9 males and 7 females, aged 46.7 (12-73), treated 1980-2005, were analyzed retrospectively.
The most common symptoms were right upper quadrant pain (56.3%) and mass in the right upper abdomen (56.3%). Alpha fetoprotein (AFP) was negative in all the patients. None was correctly diagnosed by imaging examination preoperatively. Fifteen patients underwent surgical treatment, including radical operation in 7 patients (46.7%) and palliative resection/biopsy in 8 patients. 1 patient took transcatheter hepatic arterial chemo-embolization rather than operation because of multifocal tumor. Pathological analysis diagnosed 6 patients (37.5%) as with leiomyosarcoma, 5 patients (31.25%) with angiosarcoma, 2 patients (12.5%) with fibrosarcoma, 1 patient (12.5%) with epithelioid hemangioendothelioma, 1 patient (12.5%) with myxoid liposarcoma, and 1 patient (12.5%) with undifferentiated embryonal sarcoma. The 1-year, 3-year, and 5-year survival rates were 71.4%, 41.7%, and 33.3% respectively. The 1-year, 3-year, and 5-year survival rates of the patients who received R0 were 100.0%, 83.3%, and 66.7% respectively, all significantly higher than those of the patients who did not receive R0 (all P = 0.011). The 1-year, 3-year, and 5-year survival rates of the patients with the tumor size < 5 cm were 100%, 100%, and 75% respectively, all higher than those of the patients with the tumor size > 5 cm, however, not significantly (all P = 0.084).
Liver sarcoma is difficult to be diagnosed preoperatively. Surgical resection is the mainstay of the treatment of liver sarcoma. R0 and tumor size are of prognostic values.
