System of Inspection Assisted by Microprocessor

In spite of significant advances in the field of automatic inspection (robotization, motorization), there are still numerous cases where the cost of such facilities cannot be justified due to the low production rates, or to the fact that they are not easily applicable due to the shape of the parts or to the environment (on-site maintenance inspection or inspection during manufacture in particular areas of composite parts)

Design of a System of Inspection Assisted by Microprocessor (SIAM) for Adhesive Bonded Composite Structures

The aeronautical industry makes wide use of non-destructive testing at two stages in the life of its product: during and at the end of manufacture, to guarantee the quality of the products delivered; and during service, to check and maintain the safety of its products

External beam radiotherapy boost versus surgical debulking followed by radiotherapy for the treatment of metastatic lymph nodes in cervical cancer: A systematic review and meta-analysis.

We aimed to assess disease-free survival (DFS), overall survival (OS) and treatment-related toxicity of two therapeutic strategies for treating bulky lymph nodes on imaging in patients with locally advanced cervical cancer (LACC): radiotherapy boost versus surgical debulking followed by radiotherapy. We performed a systematic review of studies published up to October 2023. We selected studies including patients with LACC treated by external beam radiotherapy (EBRT) boost or lymph node debulking followed by EBRT (with or without boost). We included two comparative (included in the meta-analysis) and nine non-comparative studies. The estimated 3-year recurrence rate was 28.2% (95%CI:18.3-38.0) in the EBRT group and 39.9% (95%CI:22.1-57.6) in the surgical debulking plus EBRT group. The estimated 3-year DFS was 71.8% and 60.1%, respectively (p = 0.19). The estimated 3-year death rate was 22.2% (95%CI:11.2-33.2) in the EBRT boost group and 31.9% (95%CI:23.3-40.5) in the surgical debulking plus EBRT group. The estimated 3-year OS was 77.8% and 68.1%, respectively (p = 0.04). No difference in lymph node recurrence between the two comparative studies (p = 0.36). The meta-analysis of the two comparative studies showed no DFS difference (p = 0.13) but better OS in the radiotherapy boost group (p = 0.006). The incidence of grade≥3 toxicities (ranging 0-50%) was not different between the two approaches in the two comparative studies (p = 0.31). No DFS and toxicity difference when comparing EBRT boost with surgical debulking of enlarged lymph nodes and EBRT in patients with cervical cancer was evident. Radiotherapy boost had better OS. Further investigation is required to better understand the prognostic role of surgical lymph node debulking in light of radiotherapy developments

Perioperative morbidity of radical trachelectomy with lymphadenectomy in early-stage cervical cancer: a French prospective multicentric cohort.

The aim of this study was to determine the predictive factors of postoperative morbidity of patients who have undergone a radical trachelectomy (RT) for early-stage cervical cancer and to assess the oncologic outcomes. We retrospectively analysed the data of 2 prospective trials on sentinel node biopsy for cervical cancer (SENTICOL I and II). Patients having a RT for early-stage cervical cancer with negative sentinel lymph node and safe margins, were included. Forty-nine patients met the inclusion criteria. Forty-five patients had a laparoscopic-assisted vaginal technique and 4 patients a total laparoscopic technique. The median age was 32 years (range, 22-46 years). 83.7% of patients had a stage IB1 disease. There were 63.3% squamous cell carcinomas and 34.7% adenocarcinomas. The median follow-up was 46 months (range, 1-85 months). Two patients (3.3%) had a severe postoperative complication (Clavien-Dindo ≥III and/or CTCAE ≥3). The main postoperative complications were urinary (28.6%), lymphovascular (26.5%) and neurologic (14.3%). On a multivariate analysis, postoperative complications were significantly associated with history of pelvic surgery and IB1 International Federation of Gynecology and Obstetrics stage. Inclusion in high surgical skills centers decrease the risk of postoperative complications. During the follow-up, 3 patients (6.1%) had a local recurrence and one patient died from a breast cancer. Between group with complications and group without any complications, overall survival and recurrence-free survival did not significantly differ at 5-year of follow-up. RT has few severe postoperative complications and appears as a safe alternative to spare fertility of young patients. To guarantee best surgical outcomes, patients should be referred to expert center

Annual outpatient hysteroscopy and endometrial sampling (OHES) in HNPCC/Lynch syndrome (LS)

Background: LS women have a 40-60 % lifetime risk of endometrial cancer (EC). Most international guidelines recommend screening. However, data on efficacy are limited. Purpose: To assess the performance of OHES for EC screening in LS and compare it with transvaginal ultrasound (TVS) alone. Methods: A prospective observational cohort study of LS women attending a tertiary high-risk familial gynaecological cancer clinic was conducted. LS women opting for EC screening underwent annual OHES and TVS. Histopathological specimens were processed using a strict protocol. Data of women screened between October 2007 and March 2010 were analysed from a bespoke database. Histology was used as the gold standard. Diagnostic accuracy of OHES was compared with TVS using specificity, and positive (PLR) and negative (NLR) likelihood ratios. Results: Forty-one LS women underwent 69 screens (41 prevalent, 28 incident). Four (three prevalent, one incident) women were detected to have EC/atypical endometrial hyperplasia (AEH), five had endometrial polyps and two had endometrial hyperplasia (EH) on OHES. TVS detected two of four EC/AEH. OHES had similar specificity of 89.8 % (CI 79.2, 96.2 %), but higher PLR 9.8 (CI 4.6, 21) and lower NLR (zero) compared to TVS: specificity 84.75 %(CI 73, 92.8 %), PLR 3.28 (CI 1.04, 10.35) and NLR 0.59 (CI 0.22, 1.58). No interval cancers occurred over a median follow-up of 22 months. The annual incidence was 3.57 % (CI 0.09, 18.35) for EC, 10.71 % (CI 2.27, 28.23) for polyps and 21.4 % (CI 8.3, 40.1) for any endometrial pathology. Conclusions: Our findings suggest that in LS, annual OHES is acceptable and has high diagnostic accuracy for EC/AEH screening. Larger international studies are needed for confirmation, given the relatively small numbers of LS women at individual centres. It reinforces the current recommendation that endometrial sampling is crucial when screening these women. © 2012 Springer-Verlag

Genetic markers and phosphoprotein forms of beta-catenin pβ-Cat552 and pβ-Cat675 are prognostic biomarkers of cervical cancer

BACKGROUND: Cervical cancer (CC) remains a leading cause of gynaecological cancer-related mortality world wide and constitutes the third most common malignancy in women. The RAIDs consortium (http://www. raids-fp7.eu/) conducted a prospective European study [BioRAIDs (NCT02428842)] with the objective to stratify CC patients for innovative treatments. A “metagene” of genomic markers in the PI3K pathway and epigenetic regulators had been previously associated with poor outcome [2]. METHODS: To detect new, more specific, targets for treatment of patients who resist standard chemo-radiation, a high-dimensional Cox model was applied to define dominant molecular variants, copy number variations, and reverse phase protein arrays (RPPA). FINDINGS: Survival analysis on 89 patients with all omics data available, suggested loss-of-function (LOF) or activating molecular alterations in nine genes to be candidate biomarkers for worse prognosis in patients treated by chemo-radiation while LOF of ATRX, MED13 as well as CASP8 were associated with better prognosis. When protein expression data by RPPA were factored in, the supposedly low molecula
