ABSTRACT

BACKGROUND: Accessing peer support can be difficult for people with, or carers of people with, inherited intellectual disabilities. One way to improve access is to provide services online, yet few studies have explored people's experiences with online peer support programmes. We aimed to explore experiences with such programmes for communities affected by fragile X-associated conditions. METHODS: Qualitative study involving individual semi-structured interviews with 16 people with, or carers of people with, a fragile X-associated condition (n = 4 adult premutation carriers; n = 12 parents/carers of children/adults), who participated in at least one of three online peer support programmes: educational webinars, Facebook discussion group and small peer group sessions via Zoom. Reflexive thematic analysis was used to develop themes. RESULTS: Three overarching themes relating to experiences were as follows: (1) uncertainty and value of shared experiences, (2) support navigating healthcare, (3) advantages being online, but still a place for in-person events. Educational webinars were perceived to be a valuable source of information about fragile X-associated conditions although people had variable information needs. Facebook discussion groups enabled people to connect with others, although participants expressed some competing preferences for how the groups were organised. Zoom peer group sessions were perceived to help participants feel supported by others, but that consistency in organisation was important. CONCLUSIONS: Online peer support programmes were perceived to be beneficial, bridging informational gaps and facilitating social connection. However, participants believed there was still a place for in-person events, some felt educational webinars did not always meet their needs and some had privacy concerns.

ABSTRACT

PURPOSE: The ultrasonographic and hemodynamic features of patients with carotid near-occlusion (CNO) are still not well known. Our aim was to describe the ultrasonographic and hemodynamic characteristics of a cohort of patients with CNO. METHODS: A prospective, observational, nationwide, and multicenter study was conducted from January/2010 to May/2016. Patients with digital subtraction angiography (DSA)-confirmed CNO were included. We collected information on clinical and demographic characteristics, carotid and transcranial ultrasonography and DSA findings, presence of full-collapse, collateral circulation, and cerebrovascular reactivity (CVR). RESULTS: One hundred thirty-five patients were analyzed. Ultrasonographic and DSA diagnosis of CNO were concordant in only 44%. This disagreement was related to the presence/absence of full-collapse: 45% of patients with CNO with full-collapse were classified as a complete carotid occlusion, and 40% with a CNO without full-collapse were interpreted as severe stenosis (p < 0.001). Mean velocities (mV) and pulsatility indexes (PIs) were significantly lower in the ipsilateral middle cerebral artery compared with the contralateral (43 cm/s vs 58 cm/s, p < 0.001; 0.80 vs 1.00, p < 0.001). Collateral circulation was identified in 92% of patients, with the anterior communicating artery (73%) being the most frequent. CVR was decreased or exhausted in 66% of cases and was more frequent in patients with a poor or absent collateral network compared with patients with ≥ 2 collateral arteries (82% vs 56%, p = 0.051). CONCLUSION: The accuracy of carotid ultrasonography in the diagnosis of CNO seems to be limited, with significant discrepancies with DSA. Decreased ipsilateral mV, PI, and CVR suggest a hemodynamic compromise in patients with CNO.

ABSTRACT

BACKGROUND AND PURPOSE: The risk of recurrent stroke amongst patients with symptomatic carotid near-occlusion (SCNO) has not been clearly established, and its management remains controversial. The aim was to define the 24-month risk of recurrent stroke and to analyse the effect of the different treatment modalities (medical treatment and revascularization) in a population of patients with SCNO. METHODS: A multicentre, nationwide, prospective study from January 2010 to May 2016 was performed. Patients with angiography-confirmed SCNO were included. The primary end-point was ipsilateral ischaemic stroke including periprocedural events within 24 months following the presenting event. Revascularization results and periprocedural complications, ipsilateral transient ischaemic attack, disabling or fatal stroke, and mortality were also noted. RESULTS: The study population comprised 141 patients from 17 Spanish centres. Seventy patients (49.6%) were treated by revascularization (carotid stenting in 47, endarterectomy in 23). Complete revascularization was achieved in 58 patients (83%). Periprocedural stroke or death occurred in 5.7%. The 24-month cumulative incidence of the primary end-point was 11.1% (95% confidence interval 5.8-16.4; n = 15), 12% in the medical treatment group and 10.2% in the revascularization group, log-rank P = 0.817. The cumulative rates of ipsilateral ischaemic stroke or transient ischaemic attack, disabling or fatal stroke, and mortality, were 17%, 4.5% and 7.5%, respectively. CONCLUSIONS: The rate of ipsilateral ischaemic stroke in patients with SCNO seems to be lower than the known rate associated with severe carotid stenosis without near-occlusion. The potential benefit of revascularization in the prevention of stroke in patients with SCNO may be influenced by the effectiveness and safety of the procedure.

ABSTRACT

BACKGROUND: ThyPRO is a recently developed thyroid-specific quality of life (QoL) questionnaire applicable to patients with benign thyroid disorders(BTD). The aim of the present study was to translate ThyPRO and ThyPRO-39 into Romanian, and to evaluate reliability and cross-cultural validity. METHODS: Standard methodology for translation and linguistic validation of patient-reported outcomes (PRO) was applied. The questionnaire was completed by 130 patients with benign thyroid diseases seen at Department of Endocrinology in the Emergency County Hospital, Tîrgu Mures, Romania, between October 2015 and March 2016. Internal reliability of the Romanian version of the ThyPRO (ThyPROro) scales was assessed for multi-item scales using Cronbach's alpha coefficient. An efficient method for testing cross-cultural validity is analysis of differential item functioning (DIF). Uniform DIF between the Romanian and the original Danish sample was investigated using ordinal logistic regression. The translation process proceeded without difficulties, and any disagreements were revised by one of the developers and the language coordinator. RESULTS: Internal reliability for ThyPRO was satisfactory. Cronbach`s alpha coefficients for the 13 scales ranged from 0.78 to 0.93 for the ThyPROro and 0.78 to 0.87 for the ThyPROro-39. In the 85-item ThyPRO, nine instances of DIF were found. Most were minor, explaining <3% of the variation in scale score, but DIF in positively worded items were larger, with explained variance (R2's) around 10-15%. CONCLUSION: The ThyPROro questionnaire is ready for assessment of health-related quality of life in Romanian patients with benign thyroid diseases.

ABSTRACT

INTRODUCTION: The expression of menin in the thyroid gland has long been debated. Animal models with targeted inactivation of menin in the thyroid gland have shown that its inactivation might play a role in the progression to a more aggressive type of cancer. Human studies are conflicting, some have identified mutations in the MEN1 gene in a sub-type of oncocytic thyroid carcinomas, while others have not identified a higher prevalence of thyroid cancer in MEN1 patients. OBJECTIVE: To analyze the immunohistochemical expression of menin in different types of thyroid carcinomas. MATERIALS AND METHODS: 48 thyroid tumours (12 papillary thyroid carcinomas (PTC), 6 anaplastic thyroid carcinomas (ATC), 12 poorly differentiated thyroid carcinomas (PDTC), 5 medullary thyroid carcinomas (MTC), 5 oncocytic follicular carcinomas (OC), 3 oncocytic adenomas (OA) and 5 goiters (G)) were tested for nuclear expression of menin using an anti-menin antibody. The expression was considered positive, negative or decreased. RESULTS: The expression of menin was positive, identical to normal tissue, in 39 cases (81.25%). The expression was decreased (n=8) or absent (n=1) in 9 tumours (18.75% - 2 PTC, 5 PDTC, 2 OC) accounting for 42% (5/12) of the PDTC and 40% (2/5) of the OC. CONCLUSIONS: Our results show that the expression of menin is generally preserved in human thyroid carcinomas, but it can be decreased or absent in certain types of thyroid cancer. Further molecular studies are needed to evaluate to potential of menin protein in tumorigenesis.

ABSTRACT

OBJECTIVES: Ta bladder tumors constitute 53% of primary bladder neoplasms, 70% of them being low-grade (G1). These tumors present a 15- 38% chance of recurrence during the first year. The aim of this paper is to identify the predicting factors of the first recurrence in a series of TaG1 primary bladder tumors. METHODS: We have retrospectively analyzed patients who were diagnosed with TaG1 primary bladder tumor by transurethral resection between 2004 and 2012. We established their tumor grade and pathological stage according to the WHO's classification guides for 1973 and 2004 as well as 2009's TNM. Those patients who were diagnosed before 2009 did not receive any adjuvant treatment. Those who were diagnosed later on received 40 mg of endovesical Mitomycin C during their immediate post operative period as their only treatment. We define recurrence as the presence of tumor after the first cystoscopy and relapse-free survival (RFS) as the period of time (in months) until the first recurrence appeared. Follow up constitutes the period of time (in months) until the last check-up or first recurrence. We also analyzed different variables: age, gender, smoking habits, muscular representation in the sample, size of the tumor (> or < 1 cm), multiple or single tumors and adjuvant treatment. The survival analysis was performed by the Kaplan-Meier method, using the long-rank test to evaluate the differences between groups. RESULTS: 68 patients were included in the study (73.5% men, 75% smokers). The average age was 61.9 years (the median being 58.5). Average follow up was 33.2 months (median 28.4). 35.3% of patients experienced recurrence. Average RFS was 19.2 ± 12.7 months (median 13.5). The majority of tumors were of a single nature (77.9%), with a size of less than 1 cm (55.9%) and with muscle representation (52.9%). 57.4% of patients did not receive adjuvant treatment. Only the absence of adjuvant treatment was associated with recurrence in uni and multivariate analysis (p<0,001), with a relative risk of 17,5 IC95% (7,6-30,2). CONCLUSION: The absence of adjuvant therapy with Mitomycin C is the only factor that, in a statistically significant way, increases the risk of recurrence, regardless of demographic factors and the characteristics of the tumor.

ABSTRACT

OBJECTIVES: To identify the post-prostatectomy prognostic factors of biochemical recurrence (BCR) and develop a predictive model for BCR based on predictive pathological variables after radical prostatectomy (RP). METHODS: We retrospectively analysed patients with clinically localised prostate cancer treated with RP as monotherapy with a minimum follow up period of 12 months. We considered BCR to be the persistence or elevation of PSA levels after RP of> 0,4 ng/ml, and rising in the following determination. We performed uni-and multivariate analysis, using the logistic regression test to determine the variables associated with BCR. We developed a mathematical model to estimate BCR, based on the variables identified, with a logistic function equation and then designed an Excel spreadsheet to apply it. Calibration and discrimination were performed by way of a Hosmer-Lemeshow test and an ROC curve. RESULTS: 693 patients were included. Average age was 63.5 years and average follow up was 88.5 months. BCR was observed in 218 patients. The average time to BCR was 35.5 months, and 90% of the cases occurred in the first 7 years. In the multivariate analysis, the PSA, Gleason Score (GS) = 7(4+3), pathological stage pT3b and affectation of the surgical margin (SM) were identified as independent prognostic pathological variables related to BCR (p〈0,001). The above four variables were included into the equation of the model. Specificity and sensitivity were 90.6% and 50.2%. Its predictive capacity was 80.5% (CI 95% 76,80 -84.3). CONCLUSIONS: PSA, GS = 7(4+3), pathological stage pT3b and PSM were found to be the independent prognostic pathological variables related to BCR-free survival. The predictive model developed permits BCR risk estimation with a reliability of 80.5%

ABSTRACT

BCRA-associated protein-1 (BAP-1) mutation has been associated with the development of a familiar syndrome that predisposes to tumors with a higher incidence than in general population, including melanoma and renal carcinoma. We report a 47-year-old woman diagnosed with a BAPoma (melanocytic tumor characterized by the loss of BAP-1). Due to her extensive family history with multiple neoplasms, a FDG PET-CT was performed. Consequently, she was diagnosed with an atypical renal mass, which is rarely linked to this syndrome. We review and discuss the available literature on the screening, diagnosis and treatment of renal tumors associated with BAP-1 tumor predisposition syndrome.

ABSTRACT

INTRODUCTION: Dynamic Contrast-Enhanced Magnetic Resonance Mammography (DCE-MRM) represents the most sensitive examination for breast cancer (BC) diagnosis. However literature data reports very inhomogeneous specificity. The aim of our study was to evaluate the clinical efficiency of a new MRM technique - diffusion weighted imaging with background body signal suppression T2 image fusion in BC diagnosis, compared to DCE-MRM. METHODS: We retrospectively analyzed 50 consecutive DCE-MRM examinations with DWIBS sequence from the archives of the Department of Radiology, Lyon Sud Hospital, (02.2010- 02.2011), summing up to 64 breast lesions. Fusions were created using the Osirix software from the DWIBS images (b=1000 s mm2) and their T2 correspondents. Interpretation was performed using an adapted BI-RADS system. The final histopathological examination or a minimum 6-months follow-up served as gold standard. RESULTS: Out of the 64 examined breast lesions, 35(54.7%) were classified as malignant by DCE-MRM and 24(37.5%) cases by DWIBS T2, respectively. Thus the DWIBS T2 fusion had a Sensitivity of 62.5%(95%CI:35.4-84.8) and a Specificity of 70.8%(95%CI:55.9-83.3) while DCE-MRM had a higher Sensitivity: 87.5%(95%CI:61.6-98.4) but a lower Specificity: 56.2%(95%CI:41.1-70.5). CONCLUSION: DWIBS T2 fusion is an innovative MRM technique, with a specificity superior to DCE-MRM, showing a large potential for improving the clinical efficiency of classical MRM.

ABSTRACT

INTRODUCTION: accurate preoperative localization of colorectal cancer (CRC) is very important, with a wide range of published error rates. AIMS: to determine accuracy of endoscopic localization of CRC in comparison with preoperative computed tomography (CT). To analyse variables that could be associated with a wrong endoscopic localization. PATIENTS AND METHODS: endoscopic and CT localization of a series of CRC without previous surgery were reviewed. We studied the concordance between endoscopic and radiologic localization against operative findings comparing accuracy of endoscopy and CT. We analysed the frequency of wrong endoscopic diagnoses with regard to a series of patient, endoscopy and tumor variables. RESULTS: two hundred thirty seven CRC in 223 patients were studied. Concordance with surgical localization was: colonoscopy = 0.87 and CT = 0.69. Endoscopic localization accuracy was:91.1%; CT: 76.2%: p = 0.00001; OR = 3.22 (1.82-5.72). Obstructive cancer presented a higher rate of wrong localization: 18 vs. 5.7% in non-obstructive tumors (p = 0.0034; OR = 3.65 (1.35-9.96). Endoscopic localization mistakes varied depending on tumor location, being more frequent in descending colon: 36.3%, p = 0.014; OR = 6.23 (1.38-26.87) and cecum: 23.1%, p = 0.007; OR = 3.92 (1.20-12.43). CONCLUSIONS: endoscopic accuracy for CRC localization was very high and significantly better than CT accuracy. Obstructive tumor and those located in the descending colon or cecum wereassociated with a significant increase of the error risk of CRC endoscopic localization.

ABSTRACT

BACKGROUND AND PURPOSE: The treatment of symptomatic carotid near-occlusion is controversial. Our aim was to analyze the results of carotid endarterectomy and carotid artery stent placement in patients with symptomatic carotid near-occlusion and to identify factors related to technical failure, periprocedural complications, and restenosis. MATERIALS AND METHODS: We conducted a multicenter, prospective nonrandomized study. Patients with angiography-confirmed carotid near-occlusion were included. We assessed the revascularization rate and periprocedural stroke or death. Twenty-four-month clinical and carotid imaging follow-up was performed, and rates of carotid restenosis or occlusion, ipsilateral stroke, and mortality were analyzed. Carotid artery stent placement, carotid endarterectomy, and medical treatment were compared. RESULTS: One hundred forty-one patients were included. Forty-four carotid artery stent placement and 23 carotid endarterectomy procedures were performed within 6 months after the event. Complete revascularization was achieved in 83.6%, 81.8% in the carotid artery stent placement group and 87% with carotid endarterectomy (P = .360). Periprocedural stroke or death occurred in 6% (carotid artery stent placement = 2.3%; carotid endarterectomy = 13%; P = .077) and was not related to revascularization failure. The carotid restenosis or occlusion rate was 8.3% (5% restenosis, 3.3% occlusion); with carotid artery stent placement it was 10.5%; and with carotid endarterectomy it was 4.5% (P = .419). The 24-month cumulative rate of ipsilateral stroke was 4.8% in the carotid artery stent placement group, 17.4% for carotid endarterectomy, and 13.1% for medical treatment (P = .223). Mortality was 12%, 4.5%, and 5.6%, respectively (P = .422). Revascularization failure and restenosis occurred more frequently in patients with full collapse compared with patients without full collapse (33.3% versus 5.6%, P = .009; 21.4% versus 2.9%, P = .032, respectively). CONCLUSIONS: Carotid artery stent placement and carotid endarterectomy are associated with high rates of failure and periprocedural stroke. Carotid near-occlusion with full collapse appears to be associated with an increased risk of technical failure and restenosis. Carotid near-occlusion revascularization does not seem to reduce the risk of stroke at follow-up compared with medical treatment.

ABSTRACT

INTRODUCTION AND OBJECTIVE: The objective of the European Randomized Study of Screening for Prostate Cancer (ERSPC) is to assess whether prostate cancer (PCa) screening leads to an improvement of cancer-specific survival. This multicenter study (eight European countries) has recruited more than 180,000 asymptomatic men. After a follow-up period of 16 years, it has been shown that PSA screening reduces PCa mortality by 20%, and that it does not affect all-cause mortality. This article provides updated the results of the Spanish arm of the ERSPC after 21 years of follow-up. MATERIALS AND METHODS: The study invited 18,612 men (aged 45 - 70) of the Spanish section (Getafe and Parla, Madrid) to participate. They were randomly assigned to the intervention arm (serum PSA-based screening) and to the control arm (follow-up without intervention). The diagnoses of PCa were recorded, as well as the PCa-specific and all-cause mortality rates. A comparison between the survival curves of both arms of the study and detailed analysis of the causes of death were performed. RESULTS: The study finally included 4,276 men (2,415 intervention arm, 1,861 control arm). The median age, serum PSA and follow-up time were 57 years, 0.9 ng/ml and 21.1 years, respectively. There were 285 cases with PCa diagnosis, 188 (7.8%) from the intervention arm and 97 (5.2%) from the control arm (p<,001). A total of 216 (75.8%) presented organ-confined disease. There were 994 deaths were recorded; 544 (22.5%) in the intervention arm and 450 (24.2%) in the control arm. No significant differences were detected between the arms of the study in terms of cancer-specific (p=.768) or all-cause (p=.192) mortality rates. The main cause of death was malignant tumors (492 patients, 49.5% of overall mortality), and the most frequent sites were lung and bronchus (29.5%), colon and rectum (14.8%), and hematologic (9.8%). Only 20 patients (0.4% of the patients recruited) died from PCa, with no significant difference between study arms. CONCLUSIONS: In this update of the results of the Spanish section of the ERSPC study after 21 years of follow-up, we have not detected a benefit of PCa screening in terms of overall and cancer-specific survival.

ABSTRACT

AIM: few data have been published regarding the causes of synchronous lesions in patients with colorectal cancer. The aim of our study was to identify potential factors that might be implicated in the development of multicentric lesions, since this knowledge could be useful for tailored follow-up once initial synchronous lesions have been removed. METHODS: we retrospectively reviewed 382 colorectal cancer cases diagnosed by total colonoscopy and histological study of surgical specimens. We divided our population into 2 groups, based on whether they had synchronous lesions or otherwise. Several data related to personal and family history, habits, symptoms, and tumor characteristics were assessed. Univariate and multivariate statistical analyses were performed. RESULTS: 208 (54.5%) patients had synchronous adenomas and 28 (7.3%) had synchronous cancer. A multivariate analysis showed that the following parameters were consistently related to the presence of multicentric lesions--male gender: OR = 1.97; CI = 1.13-3.45; p = 0.017; age = 59 years: OR = 2.57; CI = 1.54-4.29; p < 0.001; personal history of colonic adenomas: OR = 3.04; CI = 1.04-8.85; p = 0.042; and obstructive tumors: OR = 0.48; CI = 0.27-0.85; p = 0.012. CONCLUSION: our results show that several parameters that are easy to measure could be considered risk factors for the development of multicentric lesions. These factors need to be confirmed with follow-up studies analyzing their role in patients with and without metachronic lesions once all synchronous lesions have been removed.

ABSTRACT

INTRODUCTION: It's been demonstrated laparoscopic access determines a lower surgical stress, by measurement of several markers as different interleuquines (IL) or C-reactive protein (CRP). Endothelin 1 (ET-1) is a powerful vasoconstrictor produced in renal endothelium scarcely studied in laparoscopy. The objective of this study is to analyze immune response during laparoscopic and open donor nephrectomy, in a porcine experimental model by means of measuring IL-2, 10, tumoral necrosis factor alpha (TNFalpha), CRP and ET-1. METHODS: Twenty pigs underwent left nephrectomy, 10 by laparoscopy and 10 by open approach in an experimental model. Both groups were monitorized IL-2, 10, TNF alpha, ET-1 at basal, immediately post surgery, first, third, fifth and seventh days after procedure. RESULTS: The comparative analysis between groups demonstrated a significant increase in levels of CRP (1.44+/-0.88 vs 1.32+/-0.14 mg/dl, p=0.046), TNF alpha (131.14+/-41.37 vs 57.19+/-23.71 pg/ml, p>0.001) and ET-1 (0.91+/-0.49 vs 0.56+/-0.5 fmol/ml, p=0.001) of open nephrectomy group, as a higher levels of IL-2 in laparoscopic group. CONCLUSIONS: Open donor nephrectomy determines a higher immune response than laparoscopic approach. The importance of this fact over the ischemia-reperfusion syndrome or the immediate function of graft is not clearly established.

ABSTRACT

An update on aspects and use of different experimental models applied in kidney transplant research is presented . This paper includes qualities, as long as similarities between most frequently used animal models and human clinical standards. Contributions of those models based on microsurgical or laparoscopic techniques are revised. The physiological consequences (hemodynamic, immunologic) of surgical technique (laparoscopy), applied in experimental models as long as non-heart beating organ donor models and organ preservation methods are also reviewed. Finally, an update of those models applied in research in prothocols of either immunosupression or xenotransplant is done.

ABSTRACT

AIM: To analyse the frequency, characteristics and diagnosis of synchronic neoplastic lesions in colorectal cancer. METHODS: A review was carried out of 384 colorectal cancers, diagnosed through complete colonoscopy and resected. The synchronic cancers and the characteristics of the adenomas were determined: number, size, histological type, dysplasia, as well as their localisation in the colon and with respect to the carcinoma. RESULTS: Twenty-eight synchronic cancers were found (7.3% of the total); 8 developed tumours and 20 malignant polyps. In 54.4% of the cases there was a synchronic adenoma. In patients with synchronic lesions, 43% showed an advanced adenoma. Twenty percent of the synchronic polyps found were proximal to the splenic flexure; 41% were distal and 38% had both localisations. Fifty-nine point one percent of the patients had some adenoma proximal to the cancer, with criteria of advanced adenoma in 13.9%. The distribution of the adenomas was more uniformly spread in the cancers with a proximal localisation (p = 0.038). Seventeen percent of the distal cancers presented synchronic lesions with a proximal colon localisation exclusively. Partial endoscopies would diagnose the distal cancers, but would omit a synchronic adenoma in 42.3% of the sigmoidoscopies and 40% of the short colonoscopies. CONCLUSIONS: High rates of carcinoma and synchronic adenomas were registered. We underline the high index of advanced adenomas and the frequency of synchronic lesions proximal to the cancer, which is why incomplete colonoscopies, although allowing the diagnosis of the distal cancer, omit a high percentage of synchronic adenomas, including advanced lesions. All of this confirms the need to perform a complete pre-, intra- and post operational colonoscopy in resectable colorectal cancer.

ABSTRACT

OBJECTIVE: [corrected] To indirectly address the adequacy of referrals from general practitioners (GP) to specialized care taking into account a previously agreed protocol on ten urological topics. MATERIALS & METHODS: The study analyzed all referrals to the Urology department originated in 10 primary care centres (135 GPs involved) throughout a 19-month period. Adequacy of 2841 referrals was checked. The urologist judged the referral as compliant (adequate) or not compliant (inadequate) with the terms of the protocol. Compliance per primary care centres was compared. Also referral adequacy corrected per centre and clinical topic was compared. The relationship between "absolute number of referrals" and "adequate referrals" was tested using a linear regression model. RESULTS: 57.2% of the referrals were inadequate. Overall, no significant differences were detected between primary care centres. Nevertheless significant differences between centres were evident in terms of referrals due to renal colic and female urinary incontinence. 70% (94/135) of the GPs complied with the protocol in, at least, 50% of the cases. A strong association between "absolute number of referrals" and "adequate referrals" was evident (r2=0.86). CONCLUSIONS: Overall compliance with the protocol was modest. While no significant differences between centres were detected in terms of adequacy of referrals certain conditions have to be locally revisited; most of the topics (particularly microhematuria) have to be revisited in every center.

ABSTRACT

BACKGROUND: It has been postulated in the Asian literature that a low prognostic nutritional index (OI) could be associated with a higher rate of complications following radical gastric cancer surgery, but there is a lack of data concerning western countries. The aim is to analyze the relationship between a low preoperative OI and the frequency and severity of surgical complications in R0 gastric cancer resection. PATIENTS AND METHODS: In the present article, 124 cases of gastric cancer with R0 resection were reviewed. An OI <45 was considered pathologically low. The complication rate was compared between both groups: OI <45 vs OI =45. A multivariate analysis was performed adjusting for: age > 68 years, ASA score, preoperative hemoglobin level <12 g/dL, pTNM stage, administration of neoadyuvant therapy and type of gastrectomy. The relationship between a PNI<45 and the severity of complications graded according to the Clavien-Dindo classification was determined. RESULTS: We registered mild complications in 11.3% of cases, severe complications in 9.7% and a mortality rate of 2.4%. Patients with a OI <45 showed a higher complication rate: 37.7% versus 12.7% [odds ratio (OR) = 4.17; CI95% = (1.71 - 10.20 p = 0.001)], confirmed by multivariate analysis: [OR = 4.17; CI95% = (1.54 - 11.30); p = 0.005]. Patients with OI <45 had more severe complication-exitus: 20.8% versus 5.6% [OR = 4.39; CI95% = (1.31 - 14.68); p = 0.011]. CONCLUSIONS: We confirmed that patients with a low preoperative OI show a higher independent risk of complications after a R0 gastric cancer resection in a western country as well. Complications, in these cases with OI <45, registered a significantly higher severity grade.
