ABSTRACT
BACKGROUND: Postoperative intra-abdominal infection is known to adversely affect survival outcomes in patients with gastric cancer; however, previous reports have investigated this complication only in open surgery. This adverse effect is expected to be weakened by less invasive surgery, such as a laparoscopic approach, by way of maintaining immune function. METHODS: This study included 1223 patients with gastric cancer who underwent open (n = 439) or laparoscopic (n = 784) curative surgery between 2010 and 2015. For each approach, patients were divided into two groups based on presence or absence of postoperative intra-abdominal infection of Clavien-Dindo grade II or higher (C-group and NC-group, respectively). Survival outcomes were compared in propensity-matched cohorts to evaluate the impact of the complication. RESULTS: The incidences of Clavien-Dindo ≥ grade II postoperative intra-abdominal infectious complications were 9.7% (43/439) in open surgery and 9.8% (70/714) in laparoscopic surgery. After propensity score matching, 86 patients in open surgery and 138 in laparoscopic surgery were extracted for analysis. The 5-year overall survival rate in the open C-group (n = 43) was worse than that in the open NC-group (n = 43) but with no significant difference (70.9% vs. 82.8%, log-rank P = 0.18). The 5-year overall survival rates were equivalent between the laparoscopic C-group (n = 69) and the laparoscopic NC-group (n = 69) (90.5% vs. 90.4%, log-rank P = 0.99). CONCLUSION: In general, postoperative intra-abdominal infection adversely affects survival outcomes; however, its impact may be weakened by less invasive surgery. Further evaluation using larger datasets is necessary before reaching definitive conclusions.

Aim: A hiatal hernia (HH) complicates the diagnosis and surgical treatment of gastroesophageal junction (GEJ) cancer. This study aimed to investigate the effect of HH on the survival outcomes of GEJ cancer patients. Methods: This single-center study reviewed clinical data of 78 patients with GEJ adenocarcinoma who underwent R0 resection from 2008 to 2017. The patients were divided into two groups according to whether they presented with or without HH: the HH (+) group (n = 46) and the HH (-) group (n = 32). Results: Patients in the HH (+) group were older than those in the HH (-) group (69.0 vs 67.5 years, P = .018). Regarding surgical outcomes, intra-abdominal infectious complications was more common in the HH (+) group than in the HH (-) group (23.9% vs 9.4%, respectively; P = .089), particularly abscess formation (17.4% vs 3.1%, respectively; P = .036). Neither overall survival (OS) nor relapse-free survival (RFS) differed between the two groups. However, survival rates were significantly worse in a subset of patients with T3-4 disease (OS: log-rank, P = .036) (RFS: log-rank, P = .040) in the HH (+) group. In a multivariate analysis for OS in this cohort, HH was an independent prognostic factor (hazard ratio 3.60; 95% confidence interval 1.06-11.9, P = .032). Conclusion: Hiatal hernia may adversely affect surgical and survival outcomes in patients with GEJ cancer. Thus, surgical strategy must be carefully considered in these patients.
ABSTRACT
A woman in her mid-50's presented to our hospital with jaundice, fatigue, and fever. Jaundice, elevated tumor markers, and lower bile duct stricture suggested malignancy, for which subtotal stomach-preserving pancreaticoduodenectomy was performed. The patient also had annular pancreas as the second part of the duodenum was surrounded by pancreatic parenchyma. The histopathological diagnosis was adenosquamous carcinoma of the duodenal papilla associated with annular pancreas. Adjuvant chemotherapy with TS-1 was administered for 1 year. Although para-aortic lymph node metastasis was detected radiographically 3 years 9 months after surgery, the recurrence remains under control and she is alive at 5 years 9 months after surgery due to multidisciplinary therapy.

We report a case of advanced gastric cancer with right gastroepiploic vein tumor thrombus treated using preoperative S-1 plus cisplatin(CDDP)in which pathological complete response was achieved. A 78-year-old man was diagnosed with type 2 gastric cancer located at the greater curvature of the antrum, accompanied by right gastroepiploic vein tumor thrombus. Four courses of S-1 plus CDDP were administered as neoadjuvant chemotherapy. After 2 courses, computed tomography(CT) revealed the disappearance of the tumor in the right gastroepiploic vein thrombus. Distal gastrectomy with D2 lymphadenec- tomy was performed, and the diagnosis was pathological complete response(CR). Eight courses of S-1(100mg/day on days 1-28, followed by 2 weeks of rest)were administered as adjuvant chemotherapy. During the 1-year postoperative follow up, the patient showed no recurrence. An S-1 plus CDDP regimen can be a useful preoperative chemotherapy option for advanced gastric cancer with tumor vein thrombus.

We report a case involving a 65-year-old woman with skin invasion and destruction by left large breast cancer(T4cN0M0, Stage â ¢B). She had severe anemia with recurrent bleeding on the cancer surface and needed blood transfusion, and massive malodorous effusion from the skin lesion resulted in hypoalbuminemia and recurrent bacteremia. Metronidazole gel treatment for malodorous effusion and postmenopausal hormonal therapy were administered at first. After using Mohs' paste 4 times with 1- or 2-week intervals, the bleeding and effusion stopped, and the primary cancer tumor almost disappeared. Bacteremia also improved with antibiotics, and amelioration of distress was observed. Following this, systemic chemotherapy was performed. Mohs' paste was a very useful method for symptom management of malignant skin lesions with bleeding and massive effusion.
