BackgroundThe purpose of this study was to investigate the impact of the Controlling Nutritional Status (CONUT) score on survival compared with the platelet to lymphocyte ratio (PLR), the neutrophil to lymphocyte ratio (NLR), and the Glasgow Prognostic Score (GPS) in patients with resectable thoracic esophageal squamous cell carcinoma (ESCC).MethodsOne hundred eighty-five consecutive patients who underwent subtotal esophagectomy with curative intent for resectable thoracic ESCC were retrospectively reviewed. Time-dependent receiver operating characteristic curve analyses for 3-year overall survival (OS) as the endpoint were performed, and the maximal Youden indices were calculated to assess discrimination ability and to determine the appropriate cut-off values of CONUT, PLR, and NLR. The patients were then classified into high and low groups based on these cut-off values. Correlations between CONUT and other clinicopathological characteristics were analyzed. Prognostic factors predicting overall survival (OS) and relapse-free survival (RFS) were analyzed using Cox proportional hazards models.ResultsThe areas under the curve predicting 3-year OS were 0.603 for CONUT, 0.561 for PLR, 0.564 for NLR, and 0.563 for GPS. The optimal cut-off values were two for the CONUT score, 193 for PLR, and 3.612 for NLR. The high-CONUT group was significantly associated with lower BMI, high-PLR, high-NLR, and GPS1/2 groups. On univariate analysis, high-CONUT, high-PLR, high-NLR, and GPS 1/2 groups were significantly associated with poorer OS and RFS. Of these factors, multivariate analysis revealed that only the CONUT score was an independent prognostic factor for OS (HR 2.303, 95 % CI 1.191–4.455; p = 0.013) and RFS (HR 2.163, 95 % CI 1.139–4.109; p = 0.018).ConclusionsThe CONUT score was an independent predictor of OS and RFS before treatment and was superior to PLR, NLR, and GPS in terms of predictive ability for prognosis in patients with resectable thoracic ESCC.

BackgroundThe first-line treatment for resectable pancreatic cancer (RPC) is surgical resection. However, our patients have often experienced early recurrence after curative resection for RPC, with desperately poor prognosis. Some reports indicated that minimally distant metastasis not detected at operation might cause early recurrence. The present study aimed to identify preoperative clinicopathological features of early recurrence after curative resection of RPC.MethodsNinety RPC patients who underwent curative resection between 2000 and 2014 at our institution were retrospectively analyzed.ResultsOf the 90 patients, 32 had recurrence within 1 year. Univariate analysis demonstrated that preoperative serum carbohydrate antigen (CA19-9) ≥529 U/mL (P = 0.0011), preoperative serum s-pancreas-1 antigen (SPan-1) ≥37 U/mL (P = 0.0038), and histological grades G2–G4 (P = 0.0158) were significantly associated with recurrence within 1 year after curative resection. Multivariate analysis demonstrated that preoperative serum CA19-9 ≥ 529 U/mL (P = 0.0477) and histological grade G2–G4 (P = 0.0129) were independent predictors of recurrence within 1 year. Recurrent cases within 1 year postoperatively had significantly more distant metastasis than cases with no recurrence within 1 year (P < 0.001).ConclusionsPreoperative serum CA19-9 ≥ 529 U/mL and histological grades G2–G4 were independent predictive factors for recurrence within 1 year after pancreatectomy for RPC. Furthermore, recurrent cases within 1 year had more frequent distant metastasis than cases with no recurrence within 1 year. These results suggest that RPC patients with preoperative serum CA19-9 ≥ 529 U/mL should receive preoperative therapy rather than surgery.

Preoperative PNI may have merit as a gauge of prognosis for patients with GC at stages 1 and 2, but PNI and postoperative morbidity showed no correlation in this setting.

Preoperative SMI, measured in cross-section using CT, is a useful nutritional determinant that may predict OS and CSS in patients with GC who undergo gastrectomy. In our view, nutritional support for sarcopenic patients with stage I GC, aimed at retaining or adding skeletal muscle mass, may improve survival. Our analysis showed no relationship between preoperative SMI and postoperative complications.

HER2 overexpression has been linked to clinical outcomes in several solid tumors, such as breast cancer. However, the correlation between HER2 overexpression and survival in pancreatic carcinoma remains unclear. The impact of HER2 overexpression on survival in pancreatic ductal cancer was examined. Immunohistochemical staining of 129 pancreatic cancers without hematogenous metastases or peritoneal dissemination treated by macroscopically curative resection were analyzed in association with survival data. To determine HER2 overexpression in this pancreatic cancer series, the polyclonal antibody included in HercepTest, which is used worldwide for clinical examination of HER2 overexpression in breast cancer, was used. Immunoreactivity was classified according to the scale presented in the HercepTest Scoring Guidelines. Twenty-two cases (17.1%) had a score of 0, 28 cases (21.7%) had of a score of 1+, 41 cases (31.8%) had a score of 2+, and 38 cases (29.4%) had a score of 3+. Therefore, HER2 overexpression (score 2+ or 3+) was observed in 79 cases (61.2%). Patients with HER2 overexpression tumors had significantly shorter survival times than those with HER2 normal expression (score 0 or 1+) tumors (median survival time, 14.7 vs 20.7 months, respectively; P = 0.0078 on the logrank test). On multivariate survival analysis, HER2 overexpression remained an independent prognostic factor (hazard ratio, 1.806; P = 0.0258). A significant percentage of pancreatic cancers were demonstrated to have HER2 overexpression, and overexpression of this tyrosine kinase receptor proved to be an independent factor for a worse prognosis. These results should encourage further investigation of treatments using new molecular targeting agents against HER2 protein to improve the survival of pancreatic cancer patients. (Cancer Sci 2009; 100: 1243-1247) T he HER2 gene, known as ErbB-2/neu, is located on the long arm of chromosome 17 (17q12-21.32) and encodes the 185-kDa transmembrane tyrosine kinase receptor.(1) HER2 is recognized as a member of the epidermal growth factor receptor family of transmembrane receptors encoded by erbB1 (HER1 or EGFR), erbB3 (HER3), and erbB4 (HER4).(2) EGFR is the coreceptor for the formation of dimers with HER2. After a ligand binds to a single-chain EGFR, the receptor forms a dimer with HER2 that signals within the cell by activating receptor autophosphorylation through tyrosine kinase activity.(2) These dimers play a role in tumor cell proliferation, survival, adhesion, and migration. Many studies have demonstrated that HER2 overexpression is correlated with aggressiveness in breast, (4)(5)(6)(7)(8) lung, (9) and gastric carcinomas.(10,11) However, investigations correlating HER2 overexpression with survival in pancreatic carcinoma have been very limited. (12)(13)(14) The objective of this study was to examine the impact of HER2 overexpression on the survival of patients with pancreatic ductal carcinoma. Materials and MethodsPatients.
