PURPOSE: Patients with non-small cell lung cancer (NSCLC) and simultaneously having brain metastases at the initial diagnosis, presenting symptoms related brain metastasis, survived shorter duration and showed poor quality of life. We analyzed our experiences on surgical treatment of brain metastasis in patients with NSCLC. MATERIALS AND METHODS: We performed a single-center, retrospective review of 36 patients with NSCLC and synchronous brain metastases between April 2006 and December 2011. Patients were categorized according to the presence of neurological symptoms and having a brain surgery. As a result, 14 patients did not show neurological symptoms and 22 patients presented neurological symptoms. Symptomatic 22 patients were divided into two groups according to undergoing brain surgery (neurosurgery group; n=11, non-neurosurgery group; n=11). We analyzed overall surgery (OS), intracranial progression-free survival (PFS), and quality of life. RESULTS: Survival analysis showed there was no difference between patients with neurosurgery (OS, 12.1 months) and non-neurosurgery (OS, 10.2 months; p=0.550). Likewise for intracranial PFS, there was no significant difference between patients with neurosurgery (PFS, 6.3 months) and non-neurosurgery (PFS, 5.3 months; p=0.666). Reliable neurological one month follow up by the Medical Research Council neurological function evaluation scale were performed in symptomatic 22 patients. The scale improved in eight (73%) patients in the neurosurgery group, but only in three (27%) patients in the non-neurosurgery group (p=0.0495). CONCLUSION: Patients with NSCLC and synchronous brain metastases, presenting neurological symptoms showed no survival benefit from neurosurgical resection, although quality of life was improved due to early control of neurological symptoms.

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.

The aim of this study was to evaluate the diagnostic and prognostic value of clinical-positive nodes at preoperative imaging (cN1) in patients with non-metastatic renal cell carcinoma (RCC) treated with lymph node dissection (LND). We retrospectively reviewed data for a cohort of 440 consecutive patients (cN0, 76.8%; cN1, 23.2%) with cTanyNanyM0 RCC who underwent nephrectomy and LND from 1994 to 2013. Metastasis-free survival (MFS) and cancer-specific survival (CSS) were estimated using the Kaplan-Meier method. Multivariate Cox regression analysis was performed to determine significant predictors of MFS and CSS. The mean number of lymph nodes (LNs) examined for all patients was 8.3, and pN1 disease was identified in 31 (7.0%). LN staging by preoperative imaging had a sensitivity of 65%, a specificity of 80%, and an accuracy of 77%. During a median follow-up of 69 months, 5-yr MFS and CSS were 83.6% and 91.3% in patients with cN0 and 49.2% and 70.1% in patients with cN1, demonstrating a trend toward worse prognosis with radiologic lymphadenopathy (all P < 0.001). Furthermore, differences in MFS and CSS between the cN0pN0 and cN1pN0 groups were significant (all P < 0.001). Clinical nodal involvement is an important determinant of adverse prognosis in patients with non-metastatic RCC who undergo LND.

BACKGROUND/AIMS: Recurrence after hepatic resection is one of the most important factors impacting the prognosis and survival of patients with hepatocellular carcinoma (HCC). We identified prognostic factors affecting overall survival (OS) and disease-free survival (DFS) in patients with HCC after hepatic resection. METHODS: This study was of a retrospective cohort design, and 126 patients who underwent hepatic resection for HCC at Gachon University Gil Medical Center between January 2005 and December 2010 were enrolled. Various clinical, laboratory, and pathological data were evaluated to determine the prognostic factors affecting OS and DFS. RESULTS: Two- and 4-year OS and 2- and 4-year DFS were 78.1% and 65% and 51.1% and 26.6%, respectively. In a multivariate analysis, preoperative alpha-fetoprotein (> 400 ng/mL), tumor size (> or = 5 cm), multiple tumors (two or more nodules), presence of portal vein invasion, modified Union for International Cancer Control (UICC) stage III/IV, and Barcelona Clinic Liver Cancer (BCLC) stage B/C were independent prognostic factors affecting a shorter OS. In the multivariate analysis, presence of microvascular invasion, modified UICC stage III/IV, and BCLC stage B/C were independent prognostic factors for a shorter DFS. CONCLUSIONS: The presence of vascular invasion was an independent poor prognostic factor for OS and DFS in patients with HCC after hepatic resection. Thus, close postoperative surveillance for early detection of recurrence and additional treatments are urgently needed in patients with vascular invasion after hepatic resection.

BACKGROUNDWith a trend that renal tumors are being detected at an earlier stage, classical radical nephrectomy is being reconsidered. More conservative techniques are being proposed. To clarify the indication for synchronous adrenalectomy in radical nephrectomy for renal cell carcinoma which has been questioned since the 1980s, this study evaluates the role of adrenalectomy and recommends a new indication for adrenalectomy in renal cell carcinoma.

METHODSA systemic search was performed, using PubMed and Google Scholar, of all English language studies published up to March 2012 that compared adrenalectomy with adrenal-sparing surgery, in surgery for renal cell carcinoma. We assessed preoperative imaging for adrenal involvement and the relationship of tumor location with adrenal metastases. Twenty-one studies (20 retrospective and 1 prospective) involving 11 736 patients were included.

RESULTSThe mean incidence of ipsilateral adrenal involvement from renal cell carcinoma was 4.5%. Synchronous adrenalectomy did not alter survival (hazard ratio (HR) = 0.89, 95% confidence interval (CI) 0.67 - 1.19, P = 0.43; odds ratio (OR) = 1.10, 95%CI 0.84 - 1.44, P = 0.49). Upper pole tumors were not associated with a higher incidence of ipsilateral adrenal metastases. Pooled preoperative imaging: sensitivity, specificity, positive predictive value and negative predictive value were 92% (95%CI 0.84 - 0.97), 95% (95%CI 0.93 - 0.96), 71.6% and 98.5% respectively.

CONCLUSIONSAdrenal involvement from renal cell carcinoma is rare, even in advanced tumours. Synchronous adrenalectomy does not offer any benefit, even for "high risk" patients. We suggest that only patients with a positive preoperative adrenal finding on preoperative imaging for a solitary adrenal metastasis should undergo adrenalectomy as part of the radical nephrectomy.

BACKGROUNDRectal carcinoma patients are often accompanied by hepatic metastasis. The aim of this study was to evaluate the therapeutic efficacy of simultaneous laparoscopic excision for rectal carcinoma with synchronous hepatic metastasis.

METHODSA total of 41 patients with rectal carcinoma and synchronous hepatic metastasis detected by CT scan were included in this study. Among them, 23 patients underwent laparoscopic surgery and 18 patients underwent traditional open surgery to simultaneously remove the rectal tumor and hepatic metastasis lesions. All patients received postoperative adjuvant chemotherapy. All the patients were followed up from 36 to 72 months (mean 45.3 months).

RESULTSAll the operations were performed successfully and no patient was turned to open surgery in laparoscopic group. The mean blood loss, the mean postoperative hospital stay, the mean blood transfusion and the mean intestinal functional recovery time showed a significant difference between the two groups (P < 0.05). The 1-, 3- and 5-year survival rates were 82.6%, 43.5% and 8.6% in the laparoscopic group, without significant difference compared with the open group (77.8%, 38.9% and 0) (P > 0.05).

CONCLUSIONSSimultaneous laparoscopic excision for rectal carcinoma and synchronous hepatic metastasis is safe and effective with similar survival achieved by the traditional open abdominal surgery.

Radical nephrectomy with inferior vena cava (IVC) thrombectomy remains the most effective therapeutic option in patients with renal cell carcinoma and IVC tumor thrombus. Cephalic extension of the thrombus is closely related to perioperative morbidity. We purposed to design a safe and successful surgical strategy through a review of our surgical experience and treatment results in 35 patients (male:female=28:7, mean age=56 yr [32-77]) who underwent IVC thrombectomy with radical nephrectomy between January 1997 and December 2006. The limit of tumor extension was level I in 10 patients (28.6%), level II in 17 (48.6%), and level III and IV in 4 patients each (11.4%). Liver mobilization with hepatic vascular exclusion was performed in 12 patients and cardiopulmonary bypass in 7. Thirty-two primary closures, 2 patch closures, and 1 graft interposition were performed. One patient underwent simultaneous pulmonary embolectomy because of an operative pulmonary embolism. There was no operative mortality, and the overall survival at 5-yr was 50.8%. Complete thrombus removal without tumor fragmentation under long venotomy on fully exposed involved IVC is recommended for successful result in a bloodless operative field. The applicability of liver mobilization, hepatic vascular exclusion, and cardiopulmonary bypass, can be determined by the level of thrombus.

BACKGROUND/AIMS: Despite the development in diagnostic tools, gallbladder carcinoma is often diagnosed at an advanced stage. Therefore, early diagnosis and radical resection are most important factors for the prognosis of gallbladder carcinoma. However, prognostic factors after radical resection of gallbladder carcinoma have not been well identified. The aim of this study was to evaluate the prognostic factors of gallbladder carcinoma after curative resection. METHODS: We reviewed the records of the 115 patients with gallbladder carcinoma who underwent curative surgery between 1989 and 2004 at Yonsei University Medical Center (YUMC). The relationship between survival and clinicopathological variables was assessed. RESULTS: In 311 patients presenting with gallbladder carcinoma, 195 patients (62.5%) were radically resected. Among 195 patients, 80 patients were excluded because of incomplete clinicopathologic data and unsatisfactory follow-up. The 5 year overall survival rate was 36.0%, and disease free 5 year survival rate was 3.9%. Univariate analysis showed that survival was closely related to gross morphology, depth of tumor invasion, lymph node metastasis and preoperative serum CA19-9 level. Three significant factors identified by multivariate analysis were depth of tumor invasion, gross morphology, and preoperative serum CA19-9 level. CONLUSIONS: Depth of tumor invasion, gross morphology, and preoperative serum CA19-9 level are independent significant prognostic factors of resectable gallbladder carcinoma.

UNLABELLEDThe aim of this paper was to study the efficacy, side effects and complications of radiofrequency (RF) ablation of primary and metastatic liver malignancies.

MATERIALS AND METHODSWe retrospectively reviewed 57 patients (39 men, 18 women; mean age, 63 years; age range, 44 to 83 years) who underwent RF ablation for liver malignancies from January 2002 to December 2004. A total of 87 tumours were ablated - 71 (81.6%) hepatocellular carcinomas and 16 (18.4%) metastases (from primaries in the colon, stomach and pancreas). RF ablation was performed either percutaneously (n = 71) under conscious sedation or intraoperatively (n = 16) under general anaesthesia. Follow-up ranged from 1 month to 41 months (mean, 15.2) and included computed tomography (CT) 1 day, 1 month and 3 months after ablation, and half-yearly thereafter. Patients were observed for local tumour progression and for the emergence of new tumours.

RESULTSFour patients with a total of 5 tumours were lost to follow-up. Of the remaining 82 tumours treated, complete ablation was attained in 66 tumours after a single procedure, giving a primary effectiveness rate of 80.5%. Seven (8.5%) required 2 procedures to achieve complete ablation, giving a secondary effectiveness rate of 89% after 2 ablations. One tumour (1.2%) required 3 procedures to achieve complete ablation. One tumour required 4 procedures to date, with the latest follow-up CT still demonstrating incomplete ablation. Two tumours (2.4%) had an initial RF ablation and subsequent transarterial chemoembolisation (TACE). One tumour had an initial RF ablation followed by 32Phosphorus-biosilicon (BrachySil) injection, the latter as part of a Phase IIA trial. One tumour required 2 RF ablations and a subsequent TACE. Lastly, 3 tumours received initial RF ablation but subsequent local tumour progression was not treated as the patients were deemed unfit for repeat ablation. No procedure-related deaths or major complications were encountered. Minor complications were reported in 2 patients (3.8%) - subcapsular haematoma and thermal injury to the adjacent gastric antrum, both not necessitating surgical intervention.

CONCLUSIONSRF ablation is an effective, safe and relatively simple procedure for the treatment of unresectable liver malignancies.

BACKGROUND/AIMS: Although the lung is the most common site of extrahepatic spread from hepatocellular carcinoma (HCC), the role of surgery for pulmonary metastasis remains unclear. The aim of this study was to evaluate the efficacy of pulmonary resection in patients with pulmonary metastasis from HCC. METHODS: Between July 2000 and July 2004, a total of 6 patients with pulmonary metastasis from HCC underwent curative pulmonary resections. The patients were divided into two groups (Surgery group and Non-surgery group) according to the primary treatment modality of HCC. Medical records, imaging studies, and pathologic reports of the surgical specimens were reviewed. RESULTS: Three patients in the surgery group underwent pulmonary resections for a solitary metastasis after hepatectomy for HCC, and they are all still alive. One of the 3 patients developed a tumor recurrence in the chest wall after pulmonary resection. The survival time after diagnosis of HCC were 79, 122, and 54 months, respectively. The survival time after pulmonary metastatectomy were 49, 39, and 20 months in the three patients. Another 3 patients in the non-surgery group, received a pulmonary metastatectomy; they had either a complete response HCC or partial radiologic response. These 3 patients developed recurrent disease in the liver. One of 3 patients died. The survival time after diagnosis of HCC were 153, 83, 12 months. The survival time after pulmonary metastatectomy were 51, 4, 2 months. CONCLUSIONS: The surgical resections of a solitary pulmonary metastasis from HCC in highly selected patients might be an effective treatment modalities for prolonged survival.
