    Description: Background/Aim: The present study investigated the impact of the lymph node ratio (LNR) on survival and recurrence in patients with pancreatic cancer after curative surgery followed by adjuvant chemotherapy. Patients and Methods: This study included 189 patients who underwent curative surgery followed by adjuvant chemotherapy for pancreatic cancer between 2005 and 2014. The risk factors for overall survival (OS) and recurrence-free survival (RFS) were identified. Results: A lymph node ratio of 0.1 was considered to be the optimal cut-off point for classification based on the 3-year and 5-year survival rates. The OS rates at three and five years after surgery were 34.4% and 28.2% in the LNR 〈0.1 group, respectively, and 23.1% and 5.8% in the LNR ≥0.1 group, which amounted to a statistically significant difference (p=0.003). The RFS rates at one and three years after surgery were 26.6% and 20.5% in the LNR 〈0.1 group, respectively, and 8.0% and 0% in the LNR ≥0.1 group, which was a significant difference (p=0.001). A multivariate analysis demonstrated that the LNR was a significant independent risk factor for both the OS and RFS. Conclusion: The LNR was a risk factor for overall survival in patients who underwent curative surgery followed by adjuvant chemotherapy for pancreatic cancer. It is necessary to develop strategies to effectively utilize the lymph node metastasis status.

    Description: Background/Aim: Past studies have suggested that adjuvant capecitabine and oxaliplatin (CAPOX) provides decreased tumor relapse and longer survival in patients with curatively resected colon cancer. We report the first evidence of the feasibility of adjuvant CAPOX in Japanese patients with early colon cancer. Patients and Methods: Eligible patients had histologically-confirmed stage II/III colon cancer and received curative resection. The primary endpoint was completion rate of treatment after 8 cycles of adjuvant CAPOX. Results: Thirty-six patients were enrolled in this study. The completion rate of CAPOX and oxaliplatin were 77.8% and 61.1%, respectively. The incidence of grade ≥3 adverse events was neutropenia (n=6), thrombocytopenia (n=3), nausea (n=5), hand-foot syndrome (n=1) and peripheral sensory neuropathy (n=1). Three-year disease-free survival for stage II patients and stage III patients were 100% and 79.3%, respectively. Conclusion: Adjuvant CAPOX can be safely administered to Japanese patients with stage II/III colon cancer.

    Notes: Limiting molar conductances of the K+ and Cl− ions in heavy and light water have been determined at 5 °C as a function of pressure up to 1500 kgf cm−2 (1 kgf cm−2=0.9807×105 Pa) from the measured conductances and transference numbers of KCl. The residual friction coefficients (Δζ) are obtained for the cation and anion in D2O and H2O by using the determined limiting conductance and the bulk viscosity of solvent, and they are compared with the corresponding values predicted by applying the Hubbard–Onsager (HO) dielectric friction theory at various pressures below 1000 kgf cm−2. At atmospheric and high pressures, the solvent isotope and temperature effects on Δζ observed for the K+ ion are qualitatively in agreement with the theoretical prediction. However, the slightly positive pressure coefficients of Δζ(K+) are obtained in both solvents at 5 °C contrary to the theoretical prediction. Furthermore, Δζ(K+) in D2O at 5 °C is smaller than the theoretical one. These results suggest that another mechanism such as the passing through cavities one plays a more important role in ion migration of the K+ ion at lower temperatures and in D2O. On the other hand, the reverse solvent isotope and temperature effects on Δζ(Cl−), and the negative values of Δζ(Cl−) are found. These anomalies cannot be explained by the continuum theory.

    Notes: Limiting molar conductances of the K+ and Cl− ions in heavy and light water have been determined at 45 °C as a function of pressure up to 2000 kgf cm−2 (1 kgf cm−2 =0.9807×105 Pa) from the measured conductances and transference numbers of KCl. The residual friction coefficients (Δζobs ) of the K+ and Cl− ions obtained by using their limiting molar conductances and the bulk viscosity of solvent are compared up to 1000 kgf cm−2 with the corresponding values (ΔζHO ) predicted by the Hubbard–Onsager dielectric friction theory. As predicted, Δζobs for the cation in H2 O is smaller than that in D2 O and slightly decreases with increasing pressure, while its value in D2 O is almost invariant in the pressure range studied. The failure of the continuum theory in D2 O indicates that the effect of the open structure of water on the cation migration cannot be neglected even at 45 °C because of stronger hydrogen bonds in D2 O than in H2 O. For the anion, on the other hand, the continuum theory shows more serious limitations: (i) Δζobs (Cl−) in H2 O is not smaller than that in D2 O even at 45 °C with a large difference at high pressures and (ii) Δζobs (Cl−) becomes negative in both types of water at high pressures. The difference in Δζ(Cl−) between theory and experiment at 45 °C, however, becomes much smaller than that at lower temperatures.

    Notes: Limiting molar conductances of the K+ and Cl− ions in heavy and light water have been determined at 25 °C as a function of pressure up to 2 kbar from the measured conductances and transference numbers of KCl. The residual friction coefficients (Δζ) are obtained for the cation and the anion in D2O and H2O by using the determined limiting conductance and the bulk viscosity of solvent and compared with the corresponding values predicted by applying the Hubbard–Onsager (HO) dielectric friction theory at various pressures below 1 kbar. At atmospheric and high pressures Δζ of the K+ ion in D2O is larger than that in H2O just as predicted by the HO theory, but Δζ of the Cl− ion in D2O is smaller than that in H2O on the contrary to the theoretical prediction. The reverse solvent isotope effect on Δζ(Cl−) suggests that a microscopic viscosity in the vicinity of the relatively large ion is smaller than the bulk viscosity used in the continuum theory.
