    BACKGROUND: Serum and tissue human epidermal growth factor receptor 2 (HER2) levels were evaluated in resected esophageal squamous cell carcinoma (SCC) specimens to assess the relationship between HER2 expression and long-term prognosis. METHODS: We included 95 patients who underwent esophagectomy for esophageal SCC. The serum HER2-extracellular domain (sHER2-ECD) levels were measured using an ELISA kit. A time-dependent receiver operating characteristics curve for censored survival outcomes was constructed to estimate the optimal cut-off value of sHER2-ECD (set at 4211 pg/mL). Immunohistochemical (IHC) staining was performed for HER2, and specimens were classified based on low (0 or 1+) or high HER2-IHC expression (2+ or 3+). RESULTS: Patients with low sHER2-ECD levels showed poorly differentiated tumors, nodal involvement, and larger tumor size more frequently compared to patients with high sHER2-ECD levels. There were no differences in clinicopathological features based on HER2-IHC expression. Between patients with high and low HER2-IHC expression, the former group showed significantly higher sHER2-ECD levels. Patients with high sHER2-ECD levels had significantly favorable relapse-free survival (RFS) and overall survival (OS) compared to those with low sHER2-ECD levels. Conversely, patients with high HER2-IHC expression had significantly poorer RFS than did patients with low HER2-IHC expression, although no difference was observed in OS. Additionally, patients with high sHER2-ECD levels and low HER2-IHC expression had the highest OS and RFS among the patients studied. CONCLUSIONS: The correlation among sHER2-ECD levels, HER2-IHC expression, and prognosis was demonstrated. Prospective studies are required to validate the impact of serum and tissue HER2 expression in esophageal SCC prognosis.

    BACKGROUND: The aim of this study was to investigate the impact of postoperative infectious complications on adjuvant chemotherapy administration in patients with gastric cancer. METHODS: A retrospective review of 308 patients who underwent curative resection for gastric cancer was performed. Patients were divided into two groups based on the presence (90 patients, 29.2%) or absence (218 patients, 70.8%) of postoperative infectious complications to analyze clinicopathological characteristics, treatment factors and survival. RESULTS: Fewer patients with postoperative infectious complication received adjuvant chemotherapy compared to those without postoperative infectious complication. The proportion of patients who started treatment within 6 weeks after surgery was significantly lower in patients with postoperative infectious complication. The treatment completion rate was significantly lower in patients with postoperative infectious complication. The number of treatment cycles and relative dose intensity was significantly lower in patients with postoperative infectious complication. In univariate analysis, only postoperative infectious complication was significantly associated with continuation of adjuvant chemotherapy. Multivariate analysis demonstrated tumor depth, nodal involvement, postoperative infectious complication and adjuvant chemotherapy were significantly associated with overall survival. CONCLUSION: Postoperative infectious complications are significantly associated with the delay of adjuvant chemotherapy and predict adverse clinical outcome in patients with gastric cancer.

    BACKGROUND: Immunoinflammatory measures such as the neutrophil-lymphocyte ratio (NLR), the platelet-lymphocyte ratio (PLR), and the C-reactive protein (CRP)-albumin ratio (CAR) are useful prognostic measures in various malignancies. However, no study has investigated the correlation of these measures with microenvironmental inflammation. Periostin (POSTN), a small extracellular matrix protein, strongly associates with cancer microenvironmental inflammation. The current study investigated the correlation of NLR, PLR, and CAR with periostin expression in esophageal squamous cell carcinoma (ESCC). METHODS: The study retrospectively evaluated preoperative NLR, PLR, and CAR hematologically and POSTN immunohistochemically in 171 patients. The correlation of immunoinflammatory measures, POSTN expression, and survival outcomes was measured. RESULTS: The study showed a significant correlation of POSTN-positive expression with poor overall survival (OS) (P < 0.0001) and recurrence-free survival (RFS) (P = 0.03). The POSTN-positive group had higher PLR (189.6 ± 8 vs. 159.3 ± 12; P = 0.04) and CAR (0.36 ± 0.06 vs. 0.14 ± 0.09; P < 0.05) than the POSTN-negative group, whereas NLR did not differ between the two groups (3.27 ± 0.19 vs. 2.65 ± 0.28; P = 0.07). The uni- and multivariate analyses showed that POSTN-positive expression (hazard ratio [HR], 1.595; 95% confidence interval [CI], 0.770-3.031; P = 0.03), CAR (HR, 1.663; 95% CI, 1.016-2.764; P = 0.03), gender (HR, 2.303; 95% CI, 1.067-6.019; P = 0.03), and tumor depth (HR, 1.957; 95% CI, 1.122-3.526; P = 0.01) were independent prognostic factors. CONCLUSIONS: Because POSTN-positive expression strongly correlates with immunoinflammatory measures, especially PLR and CAR, it is an independent prognostic factor in ESCC.

    PURPOSES: This retrospective study investigated the effect of postoperative pneumonia on the loss of skeletal muscle volume after esophagectomy for esophageal cancer. METHODS: A total of 123 patients who had undergone esophagectomy for esophageal cancer and had (30 patients) or did not have (93 patients) postoperative pneumonia were included in the analysis. The association of clinicopathological characteristics with loss of skeletal muscle volume and long-term survival were evaluated in patients with or without postoperative pneumonia. RESULTS: There were no differences in the psoas muscle volume index (PI), lymphocyte count, serum albumin level, or prognostic nutritional index between the two groups both preoperatively and at 6 months after surgery. The decrease in PI at 6 months after surgery was significant in patients with postoperative pneumonia (- 9.9 ± 2.5%) but not in those without pneumonia (- 2.6 ± 1.6%). Patients with postoperative pneumonia had a significantly increased frequency of asymptomatic pneumonia at 6 months after surgery compared with those who did not have postoperative pneumonia (36.7% vs. 19.4%). Overall survival was significantly poorer in patients with postoperative pneumonia than in those without pneumonia (p < 0.05). CONCLUSIONS: Postoperative pneumonia was associated with the loss of skeletal muscle volume and asymptomatic pneumonia within 6 months of surgery as well as poorer overall survival.

    We report a successful dissection of metastatic posterior thoracic para-aortic lymph node (No. 112aoP) via bilateral thoracoscopic surgery. With the anesthetized patient (a 73-year-old Japanese woman) in the prone position, two working ports were inserted for the left-side approach, and artificial pneumothorax was created. Thoracoscopic examination revealed a swollen LN posterior to the descending aorta. Fat and metastatic LNs posterior to the aorta were dissected from the aortic arch level to the diaphragm while preserving intercostal arteries. For the right-side approach, two working ports were inserted and a routine thoracoscopic esophagec-tomy was performed. Gastric conduit reconstruction was achieved laparoscopically. Operation time for the left thoracic procedure: 54 min; estimated blood loss: almost none. No recurrence was detected 24 months post-operatively. There are several surgical options for approaching No. 112aoP, including transhiatal, left thora-cotomy, and thoracoscopy. Although a wide dissection of the posterior thoracic para-aortic area has not been reported, it may be feasible and safe if the artery of Adamkiewicz and intercostal arteries are preserved. A min-imally invasive bilateral thoracoscopic approach for a thoracoscopic esophagectomy is safe and useful for esophageal cancer patients with solitary No. 112aoP metastasis.
