Active clinical trials for "Neoplasms"

This retrospective observational cohort study aims to describe the impact of COVID-19 in patients treated with autologous stem cell transplantation (ASCT) for malignant disease in terms of risk factors, morbidity, need for supportive care and mortality. All patients treated with ASCT in Sweden from 1st January 2020 until 31st December 2020 are eligible for this study. Patients who also has tested positive for SARS-CoV-2 from start of conditioning or later will be identified through the national registry of the Public Health Agency of Sweden and a systematic analysis of their medical records will be performed.

This is a prospective, observational cohort study to assess the frequency with which neutropenic patients with hematologic malignancies and hematopoietic cell transplant (HCT) recipients are colonized with fluoroquinolone-resistant Enterobacterales (FQRE) and the clinical impact of FQRE colonization.

Hepatic hemangiomas are the commonest benign mesenchymal lesions of the liver. Most of these lesions are asymptomatic. Giant hepatic hemangiomas (GHH) (> 10 cm) are often symptomatic and require surgical intervention. This study aimed to describe the clinical findings, risk factors, diagnostic approach and management of GHH.

Cutaneous melanomas represent 4 to 11% of cutaneous cancers, but is responsible for 75% of the deaths reported for these pathologies. The incidence rate double every 10 years. Fourteen thousand cases and 1700 deaths were reported in France in 2015. The local staging of the cancer is represented by the Breslow index, which is measured on histological analysis, corresponding to the maximum depth of the cancer. Breslow index is a good pronostic value, and is used to choose for the best treatment for the patient. Having access to the Breslow index before the first resection of the tumor would allow dermatologists to make a complete resection with the best treatment, and the analysis of the sentinel lymph node, all during the same surgical time. Currently, patients need 2 surgeries : one before the Breslow index, and a second one after. The depth of cutaneous melanoma was already evaluated with High-Frequency Ultrasound (HF-US), but gave disappointing results, with Breslow index not being accurately measured. Only 50% of tumors less than 2mm depth were efficiently measured. Results were even worst for bigger tumors. Ultrasound biomicroscopy (UBM) is a new approach, depending on the use of ultra high frequency and large-band transducer. Nice's CHU acquired the only ultrasound device capable of applying such ultra high frequency ultrasound (UHF-US) to human tissues. The device is a VEVO MD (Vevo MD, Toronto, Canada) and equip the Ultrasound Department since June 2018. The images investigators can assess with this device have an axial resolution of 30µm, for a maximum emission frequency of 70MHz, which was not attainable until this day in human care. Furthermore, when compared to some of the mono-frequency devices investigators experimented before, this device allow investigators to attain a maximum depth of analysis up to 8mm. In consequence, this device seems to be able to realize an extremely precise analysis of the skin, and of the cutaneous melanomas, for a structural analysis, as well as a precise depth measurement, and should be evaluated in the measurement of the Breslow Index. The objective of the study is to analyze the interest of ultrasound biomicroscopy in the pre-therapeutic evaluation of the Breslow index of cutaneous melanoma, compared to histological findings. The study will include 60 patients with cutaneous melanomas, recently diagnosed in the Dermatology Department of the Nice University Hospital (Pr Bahadoran, Pr Passeron, Pr Lacour). Each patient will beneficiate from complete Ultrasound biomicroscopy analysis of the tumor The examination will be made blindly by 2 operator, both with experience in Ultra High frequency Ultrasound examinations (Dr Azulay, Dr Raffaelli). The maximum depth of the melanoma (Breslow index) will be recorded in µm. After surgical resection, the histologic analysis (Dr Long, Pr Hofman, Clinical and Experimental AnatomoPathologic laboratory, Nice's University Hospital) will measure the gold-standard Breslow Index. The comparison will analyze the capacity of Ultrasound biomicroscopy for a precise measurement of the Breslow Index, as well as the inter and intra-operator concordance. If the results of this study are positives and suggest a modification of the therapeutic strategy, a larger multicentric study would be launched in the near future.

Understanding the quality of life and anorectal function changes in patients with middle and low rectal cancer after surgery can guide patients to recover after surgery and provide a valuable reference for surgeons in the selection of surgical methods. The purpose of this study is to: (1) Investigate the complication rate, recurrence and metastasis rate and survival of patients with middle and low rectal cancer. (2) QLQ-C30 and QLQ-CR29 questionnaires were used to assess the quality of life of patients with low- and middle-level rectal cancer at different periods after surgery. (3) Wexner constipation score and LARS syndrome score for anorectal function after operation for low rectal cancer. (4) The CIPE ejaculatory function score, IIEF-5 International Erectile Function Score, and FSFI-6 Female Sexual Function Index were used to assess the changes in sexual function of patients with low- and middle-position rectal cancer after surgery.

Since its emergence in late December 2019, the SARS-CoV-2 coronavirus has spread rapidly, causing a global health crisis. The disease caused by this highly contagious respiratory virus is called COVID-19. At the beginning of August 2020, there were more than 194,000 confirmed cases in France - including approximately 16,000 cases in the Hauts-de-France area - and more than 30,300 deaths. Cancer patients are generally susceptible to respiratory infections, and CoV-2-SARS is no exception. Early Chinese studies reported a higher rate of CoV-2-SARS infection in people with cancer (or a history of cancer) than in the general population, with more severe forms and with an increased risk if surgery or chemotherapy is performed in the month prior to infection. The purpose of this study is to describe the management modalities of patients with H&N (Head and Neck) cancer during the COVID-19 pandemic in the Maxillofacial Surgery Department of CHU Amiens-Picardie.

Wilms' tumour staging and grading are used to give an idea about the prognosis. Advanced staging, diffuse anaplasia, predominant blastemal elements and lymph node invasion are indicators of poor prognosis. In spite of using the previously mentioned parameters, some tumours which were considered of low risk did not respond to therapy and eventually resulted in mortality. In contrast, other tumours assumed to be of poor prognosis responded dramatically to treatment. In light of the above, it is crucial to search for predictors of Wilms' tumour prognosis other than tumour staging and grading. Many immunohistochemical (IHC) stains have been studied as prognostic markers for nephroblastoma in literature.

WHO classification of low grade gliomas now relies on tumoral molecular patterns, especially on IDH mutation and 1p/19q co deletion status. Textural analysis on medical imaging is studied in several fields, and could provide help in patients with brain tumor due to possible complications of brain biopsy. The purpose of this study is to determine if specific textural signature on MR imaging could be found for low grade gliomas. The investigators included patients with LGG diagnosed at CHU of Nice abd whose first MRI was available on the PACS of the CHU. Textural data are extraxted by tumoral contouring and specific logiciel (LifeX) and histopathologic data are assessed for each patient. Then the investigators analyze it to dtermine if textural indices can predict molecar status.

The present study describes a 32-year-old female patient, in whom a preoperative imaging diagnosis confirmed a mass in the junction of the body and tail of the pancreas. Based on the anamnesis, on the preoperative diagnosis, and on the general status of the patient, the decision was made to performed laparoscopic enucleation of the pancreatic tumor. The operation and postoperative recovery passed without complications. A minimally invasive surgical approach should be applied whenever the dimensions and the localization of the tumor permits it, bearing in mind all the benefits and advantages that this surgical technique has to offer.

The study aims to assess the existence of intraluminal malignant cells and the appropriate fluid volume needed to perform rectal washout during transanal total mesorectal excision (taTME) for rectal cancer.
