[Show abstract][Hide abstract] ABSTRACT: An association between bullous pemphigoid (BP) and internal malignancy has been suggested. However, no reports have documented a dramatic improvement in BP after surgery for gastric cancer.
An 82-year-old Japanese woman was admitted to a local hospital for severe fatigue. On examination, she was diagnosed with BP and gastric cancer. Her BP was resistant to steroid treatment; however, it improved dramatically after surgery for gastric cancer.
In this case, a strong relationship appeared to exist between BP and gastric cancer.
This is the first report of a dramatic improvement in BP after surgery for gastric cancer.

[Show abstract][Hide abstract] ABSTRACT: Undifferentiated embryonal sarcoma of the liver (USEL) is a rare malignant hepatic tumor with a poor prognosis that is usually observed in children (aged 6 to 10 years) and rarely seen in adults. We present a case of USEL in a 27-year-old woman with no previous history of the disease. Laboratory tests performed on admission showed that the patient had mildly elevated levels of aspartate aminotransferase, alanine transaminase, alkaline phosphatase, lactate dehydrogenase, and γ-glutamyl transpeptidase. The levels of viral hepatitis and tumor serum markers were all within normal limits. Computed tomography showed a large mass involving the right lobe and the medial segment of the liver. Right trisectionectomy was performed. Microscopically, the tumor was composed of pleomorphic and polynuclear dyskaryotic cells in a myxoid stroma with focal eosinophilic globules and no clear differentiation to muscle. Histological diagnosis showed undifferentiated embryonal sarcoma. Adjuvant therapy with cisplatin, vincristine, doxorubicin, cyclophosphamide, and actinomycin D was initiated. We administered a high dose of etoposide to extract the patient's peripheral blood stem cells and performed radiation therapy and peripheral blood stem cell transplantation. At 5-year follow-up, the patient was alive without any evidence of recurrence. Here, we describe the clinical and histopathological features of USEL as well as the therapeutic options for USEL in adults with this disease.

[Show abstract][Hide abstract] ABSTRACT: Gastrointestinal neoplasia seems to be a common consequence of chronic inflammation in the gastrointestinal epithelium. Nuclear factor-kappaB (NF-κB) is an important transcription factor for carcinogenesis in chronic inflammatory diseases and plays a key role in promoting inflammation-associated carcinoma in the gastrointestinal tract. Activation of NF-κB is regulated by several posttranslational modifications including phosphorylation, ubiquitination and neddylation. In this study, we showed that tripartite motif (TRIM) 40 is highly expressed in the gastrointestinal tract and that TRIM40 physically binds to Nedd8, which is conjugated to target proteins by neddylation. We also found that TRIM40 promotes the neddylation of inhibitor of nuclear factor kappaB kinase subunit gamma, which is a crucial regulator for NF-κB activation, and consequently causes inhibition of NF-κB activity, whereas a dominant-negative mutant of TRIM40 lacking the RING domain does not inhibit NF-κB activity. Knockdown of TRIM40 in the small intestinal epithelial cell line IEC-6 caused NF-κB activation followed by increased cell growth. In addition, we found that TRIM40 is highly expressed in normal gastrointestinal epithelia but that TRIM40 is downregulated in gastrointestinal carcinomas and chronic inflammatory lesions of the gastrointestinal tract. These findings suggest that TRIM40 inhibits NF-κB activity via neddylation of inhibitor of nuclear factor kappaB kinase subunit gamma and that TRIM40 prevents inflammation-associated carcinogenesis in the gastrointestinal tract.
[Show abstract][Hide abstract] ABSTRACT: We report a case of rare long-term survival in abdominal wall hepatocellular carcinoma (HCC) metastasis. A 64-year-old man undergoing the laparoscopic microwave coagulation for HCC of the right inferior posterior segment was found three years later to have a mass at a site different from the surgical scar. The new mass was diagnosed as solitary abdominal wall HCC metastasis and resected. The elevation of tumor maker PIVKA II 7 months later led to discovery of a mass at the same site by computed tomography (CT), diagnosed as a relapse of solitary abdominal wall metastasis and necessitating reresec-tion of the mass and a rib 9. Similar PIVKA II elevation 8 months later led to diagnosis of a mass as recurrent solitary abdominal wall metastasis. Despite radiation therapy, local solitary abdominal wall metastasis recurred at the same site 5 months later, necessitating resection, after which no recurrence has been seen as of this writing.

[Show abstract][Hide abstract] ABSTRACT: There is a consensus on the indication of laparoscopy-assisted distal gastrectomy (LADG) for early gastric cancer that needs D1 + alpha or D1 + beta lymph node dissection. However, many gastrointestinal surgeons consider D2 lymph node dissection in LADG to be difficult, therefore, only a few medical institutions have performed D2 lymph node dissection in LADG. We examined the safety and accuracy of D2 dissection in LADG by comparing with open distal gastrectomy (ODG), as the first step to operate on advanced gastric cancer.
The study population comprised 53 and 67 patients who underwent D2 dissection in LADG or ODG, respectively; with the diagnosis of preoperative depth grade SM, between 2004 and 2006. In D2 lymph node dissection, difficult points are dissections of lymph node along the superior mesenteric vein (No. 14v), along the hepatic artery (No. 12a), and along the proximal splenic artery (No. 11p). We performed these lymph nodes dissection in a fixed process, which was achieved through all improvements.
No significant difference was observed in age, sex, American Society of Anesthesiology (ASA) classification, body mass index (BMI), and operative time between two groups. Bleeding volume was significantly lower in LADG (96.5 +/- 126.3 ml) than in ODG (221.9 +/- 174.8 ml). There was no significant difference in number of dissected lymph nodes between ODG (44.8 +/- 15.6) and LADG (49.2 +/- 16.1), with no significant difference in degree of pathological stage. The postoperative complication rate was 16.4% for ODG and 5.7% for LADG, and postoperative hospital stay was significantly shorter for LADG (16.7 +/- 5.6 days) than for ODG (21 +/- 11.4 days).
D2 dissection in LADG can be performed without problems with safety and accuracy, if the surgical team is skilled in the procedures of LADG.

[Show abstract][Hide abstract] ABSTRACT: Since only a few extensive reports are available on the less invasive nature of laparoscopic gastrectomy, we compared postoperative changes over time in vital signs and hematological parameters between this surgery and laparotomic gastrectomy.
Of 188 patients who underwent distal gastrectomy for preoperatively diagnosed early gastric cancer between January 2004 and September 2006, 87 underwent laparoscopy-assisted distal gastrectomy (LADG) and 101 underwent laparotomic distal gastrectomy (DG). The invasiveness of the two procedures was evaluated in 164 patients with no postoperative complications (82 cases of LADG and 82 cases of DG by measuing vital signs daily and performing hematological examination on postoperative days (POD) 1, 4, 7, and 10.
For body temperature, heart rate, and blood pressure, significantly lower values were obtained with LADG on 3 and 4 POD, 4 POD, and 3 and 4 POD, respectively. For white blood cell counts (WBC) and C-reactive protein (CRP), significantly lower values were obtained with LADG on 7 and 10 POD, and 10 POD, respectively. For serum protein levels and lymphocyte counts, significantly higher values were obtained with LADG on 1, 4, 7, and 10 POD, and 4 and 10 POD, respectively. Body temperature, WBC, and CRP showed no significant difference immediately after surgery but earlier recovery occurred with LADG. For protein levels and lymphocyte counts, higher values were obtained immediately after surgery. There seemed to be two patterns of less invasiveness in the parameters: the early recovery found for body temperature, WBC and CRP, and the smaller shift immediately after surgery in protein level and lymphocyte count, and probably, heart rate and blood pressure. The complication rate was 18.8% for DG and 5.7% for LADG.
LADG is a less-invasive surgical procedure as it produces early normalization or smaller shifts in various parameters and exhibits a low prevalence of complications.
