Recurrent syncope as a complication of recurrent neck malignancy is an uncommon but well documented association. The syncope is presumed to occur when a tumor mass invades the baroreceptor within the carotid sinus or when it disrupts the afferent nerve fibers of the glossopharyngeal nerve. A 59-year-old man presented with recurrent syncope and headache. He had a wide local excision including tonsillectomy and modified left radical neck dissection for tonsilar cancer 4 years ago. A computed tomography scan revealed ill-defined lesions in left parapharyngeal, carotid space and right upper jugular region. After clinical evaluation, cardiac pacemaker was placed, but he still suffered from the syncope. Then, he received the chemotherapy with docetaxel and cisplatin. The last hypotension event occurred on day 10 of the chemotherapy. Six months after 3 cycles of chemotherapy, he remained in complete remission and resolution of syncope. We report a case in which syncope was associated with a recurrence of tonsilar cancer and successfully treated with chemotherapy.

Locally advanced hepatocellular carcinoma (HCC) with portal vein thrombosis carries a 1-year survival rate <10%. Localized concurrent chemoradiotherapy (CCRT), followed by hepatic arterial infusion chemotherapy (HAIC), was recently introduced in this setting. Here, we report our early experience with living donor liver transplantation (LDLT) in such patients after successful down-staging of HCC through CCRT and HAIC. Between December 2011 and September 2012, eight patients with locally advanced HCC at initial diagnosis were given CCRT, followed by HAIC, and underwent LDLT at the Severance Hospital, Seoul, Korea. CCRT [45 Gy over 5 weeks with 5-fluorouracil (5-FU) as HAIC] was followed by HAIC (5-FU/cisplatin combination every 4 weeks for 3-12 months), adjusted for tumor response. Down-staging succeeded in all eight patients, leaving no viable tumor thrombi in major vessels, although three patients first underwent hepatic resections. Due to deteriorating liver function, transplantation was the sole therapeutic option and offered a chance for cure. The 1-year disease-free survival rate was 87.5%. There were three instances of post-transplantation tumor recurrence during follow-up monitoring (median, 17 months; range, 10-22 months), but no deaths occurred. Median survival time from initial diagnosis was 33 months. Four postoperative complications recorded in three patients (anastomotic strictures: portal vein, 2; bile duct, 2) were resolved through radiologic interventions. Using an intensive tumor down-staging protocol of CCRT followed by HAIC, LDLT may be a therapeutic option for selected patients with locally advanced HCC and portal vein tumor thrombosis.

BACKGROUND AND OBJECTIVEAmyloid deposition is rare. If there was a great amount of amyloid depositions in the skin tissue, it would be considered to be amyloid deposition disease at first, and then primary cutaneous marginal zone B-cell lymphoma (PCMZL). This study was to analyze the diagnosis and differential diagnosis of two cases of PCMZL with amyloid deposition.

METHODSClinicopathologic characteristics and follow-up of two cases of PCMZL were analyzed. Immunohistochemical staining was performed by EnVision method using antibodies LCA, CD19, CD20, CD79a, CD3, CD7, MUM1, kappa, lambda, Ki-67. IgH and TCRgamma gene rearrangement was detected by polymerase chain reactive (PCR).

RESULTSCase 1, a 71-year-old Chinese male, had a subcutaneous mass on the right elbow that was initially diagnosed with "amyloidosis" in 2004. Three years after the initial diagnosis, he developed recurrences on the right para-auxillary that was still diagnosed with "probably amyloidosis". Four years after the first diagnosis, the patient presented a lesion on the right para-auxillary with a diameter of 2 cm and a lesion on the temporal-parietal dural with a size of 6.0 cmx3.0 cmx3.0 cm. Case 2, a 68-year-old Chinese male, had a subcutaneous mass next to back of the left ear with a size of 9.0 cmx5.0 cm, and he underwent a operation one year previously because of subcutaneous mass in the same site. Microscopically, the tumors of both cases were located in dermis and subcutaneous, tumor cells were medium size with a nodular or diffuse distribution, and some of tumor cells were plasmacytoid/plasma cells. Morphologically, the temporal-parietal dural lesion was similar to subcutaneous lesion and infiltrated into cranial (case 1). Juxtaposed the tumor cells of two cases, there were the large amyloid deposits of amorphous hyaline material and concentrically laminated hyaline spherules in case 1, while cord-like amyloid deposits in case 2. Reactive lymphoid follicles with germinal centers and foreign body giant cells in the stroma were found surrounding the amyloid deposits. Congo red staining showed positive of amyloid deposition in tumor tissues of both cases. Immunohistochemical staining revealed that LCA, CD19, CD20, CD79a and MUM1 expressions were positive in tumor cells, and Ki-67 expression was about 8%-10%. IgL restricted expression as kappa positive while lambda negative was found in both cases. PCR results showed monoclone gene rearrangement of IgH gene in both cases.

CONCLUSIONSOur findings suggest that amyloid deposition rarely present in both primary and metastatic tumors in PCMZL, and its diagnosis should be considered to avoid misdiagnosis. The patients with PCMZL should undergo regular examinations and chemotherapy as well as a long-term follow-up since it is apt to recur or relapse.

Gastric cancer is the second most common cause of cancer death worldwide and is usually detected at a late stage, except in Korea and Japan where early screening is in effect. Results from animal and epidemiological studies suggest that Helicobacter pylori infection, and subsequent gastritis, promote development of gastric cancer in the infected mucosa. Relatively effective treatment regimens are available to treat H. pylori infection, and in general, mass eradication of the organism is not currently recommended as a gastric cancer prevention strategy. However, regional guidelines vary regarding the indications and recommendations for H. pylori treatment for gastric cancer prevention. In this review, we discuss the results from intervention studies, provide insight regarding current guideline recommendations, and discuss future study directions.

BACKGROUNDRapid clearance of peripheral blood blasts (PBBs) predicts complete remission (CR) and survival in patients with acute myeloid leukemia (AML). We aimed to explore the correlation between induction therapy response, outcome, and the PBB percentage.

METHODSForty-six consecutive patients with de novo AML (excluding acute promyelocytic leukemia) were enrolled in this study. Flow cytometry was performed to identify cells with a leukemia-associated aberrant immunophenotype in the initial bone marrow aspirate and in peripheral blood on day 7 of induction therapy.

RESULTSThe PBB percentage on day 7 (D7PBBP) was significantly lower in patients who achieved CR (0.03% (0.0%, 0.45%)) than in those who did not (10.85% (1.13%, 19.38%); u = -3.92, P < 0.001). The CR rate was significantly higher among patients with a D7PBBP of <0.945% (84.62%, 22/26) than among those with a D7PBBP of = 0.945% (25.0%, 5/20; χ2 = 16.571, P < 0.001). D7PBBP was significantly correlated with overall survival (OS; r = -0.437, P = 0.003) and relapsefree survival (RFS; r = -0.388, P = 0.007). OS and RFS were significantly higher in patients with a D7PBBP of <0.43% than in those with a D7PBBP of ≥ 0.43% (P < 0.001 and P = 0.039, respectively). D7PBBP was also found to be an independent prognostic indicator in multivariate analysis for both OS (P = 0.036) and RFS (P = 0.035).

CONCLUSIOND7PBBP may be an important risk factor for the achievement of complete remission, for overall survival, and for relapse-free survival.

BACKGROUND/AIMS: Sorafenib is currently the sole molecular targeted agent that improves overall survival in advanced hepatocellular carcinoma (HCC). Despite the efficacy of sorafenib, the response rate varies in patients with advanced HCC. We retrospectively analyzed a series of Korean patients with advanced HCC with complete remission (CR) after sorafenib therapy. METHODS: In total, 523 patients with advanced HCC were treated with sorafenib in 3 large tertiary referral hospitals in Korea. A survey was conducted to collect data on patients who experienced CR after sorafenib monotherapy, and their medical records and follow-up data were analyzed. The tumor response and recurrence rates were assessed by radiologic study, based on modified response evaluation criteria in solid tumors. RESULTS: Seven patients with advanced HCC experienced CR after sorafenib therapy. The median time to tumor disappearance and the median disease-free survival time were 3 months and 9 months, respectively. HCC recurrence was identified in three cases (42.9%). Of these, two patients discontinued sorafenib before or after achieving CR and the other patient continued sorafenib after achieving CR. HCC recurred at 3, 10, and 42 months after CR in these three patients. Three patients needed dose reduction for toxicity and adverse events. CONCLUSIONS: Though CR was achieved after sorafenib therapy in patients with advanced HCC, the recurrence rate was relatively high. Subsequent strategies to reduce a chance of recurrence after sorafenib therapy are required to investigate.

OBJECTIVETo study the clinicopathologic features of 66 cases of primary systemic anaplastic large cell lymphoma (ALCL), with emphasis on the differences between ALK-positive and ALK-negative cases.

METHODSThe clinical data of 66 cases of ALCL was analyzed. The histologic features were reviewed. Immunohistochemical study for CD30, ALK protein, epithelial membrane antigen, CD2, CD3, granzyme B and TIA-1 was carried out. In-situ hybridization for small mRNA of Epstein-Barr virus (EBER) was also performed. The chromosomal abnormalities were studied by fluorescence in-situ hybridization (FISH). The differences between ALK-positive and ALK-negative cases were statistically analyzed.

RESULTSThere were 48 cases of ALK-positive ALCL and 18 cases of ALK-negative ALCL. The patients with ALK-positive ALCL were younger than those with ALK-negative ALCL (P < 0.05), with the median age being 18 years and 36 years, respectively. Fever, especially hyperpyrexia, was more commonly observed in ALK-positive ALCL patients than in ALK-negative ALCL patients (33 cases versus 4 cases, P < 0.05). The overall survival rate and median duration of survival in patients with ALK-positive ALCL were higher and longer than those in patients with ALK-negative ALCL (80% versus 71%; 21 months versus 12.5 months, P > 0.05). There were however no significant differences in histology between ALK-positive ALCL and ALK-negative ALCL. Histologically, most cases showed diffuse growth pattern. Nodular pattern was demonstrated in a minority of cases. "Hallmark" cells were seen in most of the ALCL cases. Focal necrosis and myxomatous stroma were identified in a few cases. Most ALK-positive cases belonged to the common variant (35 cases). A small number represented lymphohistiocytic variant (8 cases). Small cell variant and sarcomatoid subtype were found only in few cases (3 cases and 2 cases, respectively).On the other hand, common variant (17 cases) constituted the majority of ALK-negative ALCL. Lymphohistiocytic variant was seen in only 1 case. Immunohistochemical study showed that ALK-positive ALCL always expressed CD30 and epithelial membrane antigen. ALK-positive ALCL more often expressed epithelial membrane antigen (100% versus 72%; P < 0.05) but less so for T-cell markers (including CD2, CD3, CD43 and CD45RO). Cytotoxic molecules were more commonly expressed in ALK-positive ALCL (P > 0.05). EBER was negative in all cases studied. FISH showed that in ALK-positive ALCL, 1 case had normal ALK gene, 1 had deletion and multicopy and 2 had deletion. On the other hand, 1 case of ALK-negative ALCL had normal ALK gene.

CONCLUSIONSWhile there are no significant morphologic differences between ALK-positive ALCL and ALK-negative ALCL, the clinical features, immunophenotypes and genetic features of both groups vary. These differences are helpful in guiding the differential diagnosis.

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.
