METHODS： From January 2001 to December 2006, 487 patients with histologically confirmed primary gas- tric adenocarcinoma were diagnosed with stage 11 gas- tric cancer according to the new 7th edition American Joint Committee on Cancer stage classification at the Department of Gastric Cancer and Soft Tissue Surgery, Fudan University Shanghai Cancer Center. All patients underwent curative gastrectomy with standard lymph node （LN） dissection. Fifty-one patients who died in the postoperative period, due to various complications or other conditions, were excluded. Clinicopathologicalfindings and clinical outcomes were analyzed. Patients were subdivided into four groups according to the status of LBVI and LN metastases. These four patient groups were characterized with regard to age, sex, tumor site, pT category, tumor grading and surgical procedure （subtotal resection vs total resection）, and compared for 5-year overall survival by univariate and multivariate analysis. RESULTS： The study was composed of 320 men and 116 women aged 58.9 ± 11.5 years （range： 23-88 years）. The 5-year overall survival rates were 50.7% and the median survival time was 62 too. Stage Ⅱ a cancer was observed in 334 patients, including 268 T3N0, 63 T2N1, and three TIN2, and stage Ⅱb was observed in 102 patients, including 49 patients T3N1, 51 T2N2, one TIN3, and one T4aN0. The incidence of LBVI was 28.0% in stage II gastric cancer with 19.0% （51/269） and 42.5% （71/167） in LN-negative and LN- positive patients, respectively. In 218 patients （50.0%）, there was neither a histopathologically detectable LBVI nor LN metastases （LBVI-/LN-, group I）; in 51 patients （11.7%）, LBVI with no evidence of LN me- tastases was detected （LBVILN-, group 11）. In 167 patients （38.3%）, LN metastases were found. Among those patients, LBVI was not determined in 96 patients （22.0%） （LBVI-γLN, group Ⅲ）, and was determined in 71 patients （16.3%） （LBVI＋LN＋, group Ⅳ）. Correla- tion analysis showed that N category and the number of positive LNs were significantly associated with the presence of LBVI （P 〈 0.001）. The overall 5-year sur- vival was significantly longer in LN-negative patients compared with LN-positive patients （56.1% vs 42.3%, P = 0.015）. There was a significant difference in the overall 5-year survival between LBVI-positive and LBVI- negative tumors （39.6% vs 54.8%, P = 0.006）. Overall 5-year survival rates in each group were 58.8% （ Ⅰ）, 45.8% （Ⅱ）, 45.7% （Ⅲ） and 36.9% （Ⅳ）, and there was a significant difference in overall survival between the four groups （P=-0.009）. Multivariate analysis in stage 11 gastric cancer patients revealed that LBVI in- dependently affected patient prognosis in LN-negativepatients （P = 0.018） but not in LN-positive patients （P = 0.508）. CONCLUSION： In LN-negative stage 11 gastric cancer patients, LBVI is an additional independent prognostic markeF, and may provide useful information to identify patients with poorer prognosis.展开更多

Several studies have shown how depression tends to exacerbate coexisting chronic heart failure and its clinical outcomes and vice versa, especially in the elderly. The negative synergism between chronic heart failure and depression in the elderly may be approached only taking into account the multifaceted pathophysiological characteristics underlying both these conditions, such as behavioural factors, neurohormonal activation, inflammatory mediators, hypercoagulability and vascular damage. Nevertheless, the pathophysiological link between these two conditions is not well established yet. Despite the high prevalence of depression in chronic heart failure elderly patients and its negative prognostic value, it is often unrecognized especially because of shared symptoms. So the screening of mood disorders, using reliable questionnaires, is recommended in elderly patients with chronic heart failure, even if cannot substitute a diagnostic interview by mental health professionals. In this setting, treatment of depression requires a multidisciplinary approach including： psychotherapy, antidepressants, exercise training and electroconvulsive therapy. Pharmacological therapy with selective serotonin reuptake inhibitors, despite conflicting results, improves quality of life but does not guarantee better outcomes. Exercise training is effective in improving quality of life and prognosis but at the same time cardiac rehabilitation services are vastly underutilized.展开更多
