ABSTRACT
Objective:To analyze the correlation between cognitive impairment and cortical atrophy in elderly patients with asymptomatic carotid artery stenosis (ACAS).Methods:In this cross-sectional study, 40 consecutive elderly patients with ACAS treated in the Department of Neurology, Northern Jiangsu People′s Hospital from July 1, 2020 to June 30, 2021 (ACAS group), and 40 elderly healthy controls who accepted physical examination during the same period (control group) were included. Cognitive assessment was performed using the Mental State Examination Scale (MMSE) and the Montreal Cognitive Assessment Scale (MoCA), and brain magnetic resonance imaging scanning was performed in the ACAS group. The artificial intelligence technique was applied for brain lobe segmentation and cortical volume calculation. The χ2-test, independent sample t-test and Wilcoxon non-parametric test were used to analyze the difference of clinical data and cognitive scores between the two groups. In the ACAS group, the cortical volumes of the side with carotid stenosis was compared with that of the normal side, and Spearman′s correlation analysis was used to assess the correlation between cognitive scores and cortical atrophy. Results:Compared with the control group, the ACAS group got significantly lower scores of MMSE and MoCA, as well as lower scores of visuospatial executive function, attention and calculation, language function, abstraction ability and delayed recall [(25.60±2.49) vs (27.18±1.01), (22.05±3.59) vs (25.60±1.43), (2.73±1.04) vs (4.08±0.62), (4.53±0.93) vs (5.03±0.66), 2.00 (0.00) vs 3.00 (0.00), 1.00 (1.00) vs 2.00 (0.00), and (2.95±0.96) vs (3.35±0.62)] (all P<0.05). There was not significant differences in naming and orientation ability between the two groups (both P>0.05). The volume of cortical, temporal lobe, frontal lobe, parietal lobe and insular lobe on the side with carotid stenosis in the ACAS group were significantly smaller than those on the normal side [186.23 (177.97, 202.53) vs 194.67 (185.65, 204.82) cm 3, 54.74 (50.66, 56.95) vs 55.61 (51.24, 58.49) cm 3, 72.98 (70.76, 78.34) vs 75.27 (72.34, 80.66) cm 3, 53.66 (51.11, 57.86) vs 56.59 (52.80, 60.09) cm 3, 6.57 (6.35, 7.07) vs 6.72 (6.46, 7.34) cm 3] (all P<0.05). The MoCA score in the ACAS group was positively related to the cortical volume ratio of the two sides ( r=0.427, P<0.01). The attention ( r=0.353) and abstraction ( r=0.226) ability scores were positively correlated with the temporal lobe volume ratios of the two sides (both P<0.05). The visuospatial executive ( r=0.187) and language ( r=0.373) ability scores were positively correlated with frontal lobe volume ratios of the two sides (both P<0.05), and visuospatial executive ( r=0.386), naming ( r=0.344), language ( r=0.517), abstraction ( r=0.335) and delayed recall ( r=0.333) ability scores were positively correlated with parietal lobe volume ratios of the two sides (all P<0.05). Conclusion:In elderly patients with ACAS, the cognitive impairment and cortical atrophy on the sides with carotid stenosis are significant and a positive correlation is detected between them.
ABSTRACT
Objective To investigate the high-risk factors of retroperitoneal lymph nodes metastasis (LNM) and the effect of lymph nodes metastasis on prognosis in patients with endometrial carcinoma (EC).Methods Retrospec-tive research was carried out from January 2005 to December 2010 to identify 289 endometrial carcinoma patients treated with retroperitoneal lymphadenectomy at Peking Union Medical College Hospital.The high-risk factors of retroperitoneal LNM and prognostic factors of this disease were studied.Results 1) The median age at diagnosis was 55 years old.Patients of stage Ⅰ, Ⅱ, Ⅲ and Ⅳ were 224 (77.5%), 13 (4.5%), 45 (15.6%) and 7 (2.4%), respectively.Two hundred and eighty-nine patients received pelvic lymphadenectomy, of that 30 (10.4%) patients were found the pelvic LNM.Ninety-six patients received periaortic lymphadenectomy, of that 11 (11.5%) patients were found the periaortic LNM.Twenty-one (7.3%) patients developed recurrent disease and 11 (3.8 %) dead.The median follow-up was 37 months and the median disease-free survival (DFS) was 34 months.2) In univariate analysis, the incidence of LNM significantly increased in patients with CA125 ≥ 35 U/mL preoperatively, non-endometrioid adenocarcinoma, low grade, deep myometrium invasion, diameter of tumor ≥ 2 cm, cervical stroma involvement, positive peritoneal cytology and vagina or parametrial involvement (P<0.05).In multivariate analysis, CA125 ≥ 35 U/mL preoperatively, low grade, deep myometrium invasion were the independent high-risk factors of LNM (P<0.05).3)The Kaplan-Meier analysis showed a significant difference between positive peritoneal cytology, vagina or parametrial involvement, appendix involvement, LNM and DFS (P<0.05).We also found a significant difference in the impact of non-endometrioid adenocarcinoma, low grade, deep myometrium invasion, positive peritoneal cytology, appendix involvement and LNM on overall survival (OS) (P<0.05).Cox regression analysis revealed retroperitoneal LNM is the independent prognostic factor of 5-year DFS (patients without LNM 92.1% vs patients with LNM 65.3%, P=0.002, 95% CI 0.078-0.552).We also found the trend that the 5-year OS was higher in patients without LNM than them with LNM, even though there was no significant difference(patients without LNM 96.1% vs patients with LNM 70.0%, P=0.086, 95% CI 0.039-1.238).Conclusions 1) there is a predictive value of low grade and deep myometrium invasion for EC patients with LNM.2)Patients with LNM have poorer prognosis than them without LNM.Therefore, patients with LNM should receive adjuvant therapy to reduce the risk of recurrence.
ABSTRACT
Objective To investigate the clinical characteristics and treatments of endometrioid carcinoma patients with preoperative diagnosis of endometrial hyperplasia.Methods From 2005 to 2010, 404 patients were diagnosed with endometrioid carcinoma after hysterectomy.Among these patients,44 of them were diagnosed atypical endometrial hyperplasia(AEH) preoperatively.Retrospectively analysis the characteristics of these patients with SPSS13.0.Results Among the 44 cases, all of them were grade G1 disease, and 39 of them received comprehensive staging surgery.14(32%)young cases preserved bilateral ovaries.9 cases(20%) were given adjuvant radiology.No recurrence was detected during the median follow up of 52 months.Compared to the premenstrual group, although no statistical difference was detected, more patients with risk factors of deep myometrium invasion(4/22 vs 1/22) and lymph-vascular space invasion(LVSI, 3/22 vs 0/22) in the postmenstrual group.Compared to the patients who diagnosed with endometrioid cancer(EC) preoperatively, there are more patients with grade G1(P=0.000), fewer patients received adjuvant chemotherapy(P=0.003) and fewer recurrence(P=0.019) in AEH group.Conclusions The endomtrioid cancer patients who diagnosed with atypical hyperplasia preoperatively have better prognosis.Hysterectomy with bilateral ovaries preserved is acceptable in young patients.Post menopause patients have more risk factors of deep myometrium invasion and LVSI.
ABSTRACT
Objective To determine the prognostic significance of positive peritoneal cytology (PPC) among patients with endometrial cancer and to find out potential risk factors for PPC in endometrial cancer.Methods Data were extracted from Peking Union Medical College Hospital between Jan 1 2005 and Dec 31 2010.Only those patients who had undergone a staging procedure were included.A total of 486 patients were identified.Statistical analyses were performed using Fisher`s exact test, Kaplan-Meier log rank, and Cox proportional hazards models.ResultsRate of PPC was 4.8% in endometrial cancer.Non-endometrioid endometrial cancer(P=0.000), stage Ⅲ/Ⅳ(P=0.000), deep myometrial invasion(P=0.001), and cervical stromal involvement(P=0.018) appeared to be risk factors for PPC in endometrial cancer.Univariate analysis revealed statistically difference in 5-year PFS (70.9% vs 90.0%) and 5-year OS (72.2% vs 96.0%).Progression-free survival and overall survival showedstatistically difference(P=0.005,P=0.000)between PPC and NPC endometrial cancer.On multivariate analysis, PPC remained no statistically difference in progression-free survival or overall survival(RR=3.812,95% CI 0.897-16.200,P=0.070;RR=3.426,95% CI 0.800-14.673,P=0.097).Conclusions PPC is not an independent risk factor in patients with endometrial cancer.Aggressive histology, FIGO stage, deep myometrial invasion and cervical stromal involvement are presumed to be associated with PPC in endometrial cancer.
