Background: The aim of this study was to determine whether or not the short- and long-term outcomes were affected by the age-adjusted Charlson comorbidity index (ACCI) in patients who underwent curative resection for gastric cancer.Methods: The patients were retrospectively selected from among the medical records of consecutive patients who underwent curative gastrectomy with nodal dissection for gastric cancer at Yokohama City University and Kanagawa Cancer Center from January 2000 to August 2015.Results: A total of 2254 patients were eligible for inclusion in the present study. One thousand six hundred fifty-six patients had an ACCI of <6 points (ACCI low group), while 598 had a score of ≥6 points (ACCI high group). The median age (p<0.001) and American Society of Anesthesiologists physical status (ASA-PS) score (p<0.001) of the ACCI high group were higher in comparison to the ACCI low group. The incidence of surgical complications in the ACCI high group was significantly higher than that in the ACCI low group (12.0% vs. 7.2%, p<0.001). Univariate and multivariate analyses demonstrated that an ACCI high classification was a significant risk factor for postoperative complications. In addition, the 5-year OS rates of the ACCI low and ACCI high groups were 85.4% and 74.1%, respectively. The difference was statistically significant (p<0.001). The univariate and multivariate analyses demonstrated that an ACCI high classification was a significant prognostic factor for OS.Conclusions: Our results support that a high ACCI value is an independent risk factor for the short- and long-term outcomes of patients with gastric cancer. To improve the survival of patients with gastric cancer, it is necessary to carefully plan the perioperative care and the surgical strategy according to the ACCI.

Background/Aim: We investigated the impact of the age-adjusted Charlson comorbidity index (ACCI) on esophageal cancer survival and recurrence after curative treatment. Patients and Methods: This study included 122 patients who underwent curative surgery followed by adjuvant chemotherapy for esophageal cancer between 2005 and 2017. The risk factors for the overall survival (OS) and recurrencefree survival (RFS) were identified. Results: An ACCI of 5 was regarded as the optimal critical point of classification considering the survival rates. The OS rates at 3 and 5 years after surgery were 64.2% and 54.4% in the low-ACCI group, respectively, and 42.3% and 29.2% in high-ACCI group, respectively (p=0.035). The RFS rates at 3 and 5 years after surgery were 50.2% and 43.6% in the low-ACCI group, respectively, and 28.5% and 21.3% in high-ACCI group, respectively (p=0.021). A multivariate analysis demonstrated that ACCI was a significant independent risk factor for both the OS and RFS. Conclusion: ACCI is a risk factor for survival in patients who undergo curative treatment for esophageal cancer. An effective plan for the perioperative care and surgical strategy should be developed according to ACCI. Esophageal cancer is the seventh-most common cancer and the sixth leading cause of cancer-related mortality. An 2783 This article is freely accessible online.

Background: We investigated the clinical influence of anastomotic leak (AL) on esophageal cancer survival and recurrence after curative surgery. Patients and Methods: This study included 122 patients who underwent curative surgery for esophageal cancer between 2008 and 2018. The patients were classified into those with AL and those without. The risk factors for overall (OS) and recurrence-free (RFS) survival were identified. Results: AL was found in 44 out of the 122 patients (36.1%). The respective OS rates at 3 and 5 years after surgery were 43.9% and 40.2% in the AL group and 63.9% and 53.2% in the non-AL group, which were significantly different (p=0.0049). In contrast, the respective RFS rates at 3 and 5 years after surgery were 44. 8% and 29.8%, and 44.9% and 42.4%, which were not significantly different (p=0.2306). A multivariate analysis showed that AL was a significant independent risk factor for both poorer OS and RFS in patients who underwent curative surgery for esophageal cancer. Conclusion: To improve survival of patients with esophageal cancer, the surgical procedure, perioperative care and surgical strategy must be carefully planned in order to prevent AL.

Background Hereditary motor and sensory neuropathy with proximal dominant involvement (HMSN‐P) is characterized by adult onset, a slowly progressive course and autosomal dominant inheritance. It remains unclear whether myopathic changes occur histopathologically. Methods We encountered 2 patients in a family with a heterozygous p.P285L mutation in TRK‐fused gene (TFG), which is known to cause HMSN‐P. The affected individuals developed proximal‐dominant muscle weakness in their 40s, which slowly progressed to a motor neuron disease‐like phenotype. Results Muscle biopsy showed myopathic pathology including fiber size variability, increased internal nuclei, fiber splitting, and core‐like structures, associated with neurogenic changes: large groups of atrophic fibers and fiber type‐grouping. Immunohistochemistry revealed sarcoplasmic aggregates of TFG, TDP‐43, and p62 without congophilic material. Conclusions The present study demonstrates myopathic changes in HMSN‐P. Although the mechanisms underlying the skeletal muscle involvement remain to be elucidated, immunohistochemistry suggests that abnormal protein aggregation may be involved in the myopathic pathology.
