A French Multicenter Observational Retrospective Study of Rare Primary Liver Cancers

The aim is to describ rare primary hepatic cancers clinical, histological and radiological features, to obtain a biological tumor and blood collection, and to evaluate the efficacy of treatments received in clinical practice in order to determine optimal therapeutic sequences.

Reduction of Breast Hypertrophy by Means of Coelioscopique Surgery

Breast reductions are common procedures. One of the main difficulties related to this surgery remains the healing, wide at the peri-areolar level, vertical at the sub-areolar level and in the sub-mammary fold. In addition, this intervention remains subject to the vagaries of hypertrophic or even keloidal healing, especially in young subjects. On This study can be expected to scientifically validate the use of laparoscopic surgery to obtain a clinical result without scarring in the context of the reduction of medium volume breast hypertrophy. Ultimately, the results of this study may serve as a basis for further research by proposing: - Prophylactic mastectomies and immediate breast reconstruction without lateral scar and with a less visible sub-breast scar. - A breast reduction in young patients before the skin undergoes the effects of the heaviness of the breasts.

Efficacy of Cotrimoxazole as a De-escalation Treatment of Ventilator-Associated Pneumonia in Intensive Care Unit

Multicentre randomized non-inferiority trial comparing cotrimoxazole to standard antibiotic therapy for enterobacterial VAP. Selection of patients will be done by physicians in ICU. All clinically suspected VAP will be confirmed with a lung sample (preferably bronchoalveolar lavage or protected distal specimen, otherwise endotracheal aspiration). Patients with a microbiologically confirmed VAP due to an Enterobacteriaceae susceptible to cotrimoxazole and at least one antibiotic of the empiric antibiotic therapy (based on international recommendations) will be included. After written informed consent, they will be randomized (1:1), using a computer-generated randomization scheme of various-sized blocks, stratified by presence of septic shock at VAP diagnosis and by presence of COVID-19 pneumonia on ICU admission, through a centralized 24 hours internet service (CleanWEB™) to cotrimoxazole, or best standard of care (either a beta-lactam or a fluoroquinolone), after randomization for a total duration of 7 days (including empiric initial appropriate treatment). Posology and modalities of antibiotic administration will be optimized based on most recent recommendations for ICU patients. Because antibiotic therapy will be variable in the control group, single or double blind is not appropriate. Daily follow-up until death or ICU discharge or day 28 will be performed (vital status, antibiotic therapy, new infection, Clostridium-difficile infection). Clinical (arterial blood gas, temperature, haematology, tracheal secretions) and radiological cure (chest X-ray) will be assessed at Day 7. Systematic MDR bacteria screening will be performed weekly and at ICU discharge. Vital status will be assessed at day 90. Alive patients leaving ICU before 90 days will be contacted by phone (if discharge at home) or by interview at hospital (if transferred in a different ward). Assessment of the clinical and radiological cure by an independent committee (1 specialist in infectious disease and 1 intensivist), blinded of the randomization arm (PROBE methodology).

Systematic Use of DDAVP to Prevent Serum Sodium Overcorrection in Severe Hyponatremia

Multicentre, prospective, open-label randomized controlled superiority trial with stratification on the presence of neurological symptoms at inclusion and on the presence/absence of risk factors for central pontine myelinolysis (chronic alcohol abuse, malnutrition, serum potassium < 3.0 mmol/L). Patients in ICU with severe hyponatremia defined by SNa < 115 mmol/L or SNa < 120 mmol/L in the presence of neurological symptoms (convulsions, stupor defined by a Glasgow score <12 or signs of brain herniation) and a normal or decreased extracellular fluid volume will be included. After written informed consent, they will be randomized (1:1), using a computer-generated randomization scheme of various-sized blocks, stratified by the presence of neurological symptoms at inclusion (seizures, stupor defined as Glasgow score <12 or signs of brain herniation) and on the presence/absence of risk factors for central pontine myelinolysis (chronic alcohol abuse [defined according to World Health Organization definition], malnutrition [BMI<20.5 or weight loss >5% in 3 months], serum potassium < 3.0 mmol/L), through a centralized 24-hour Internet service (CleanWEB™), to receive standard hyponatremic treatment alone or standard hyponatremic treatment and DDAVP 4 μg/ml IV, after randomisation and for a total duration of 48 hours. Since administration of DDAVP leads to an important decrease in urine output and increase in urine osmolarity which are clinically obvious very rapidly, a single or double blind trial is not appropriate. However, all investigators will be unaware of aggregate outcomes during the study and brain MRI imaging will be performed and analyzed blinded to the randomization group

Survival and Description of Care for Patients With Degenerate Vaterian Ampulloma

A Vater's ampulloma is a rare digestive tumour which accounts for under 1% of all digestive tumours. In terms of incidence, it is the 3rd most common biliary tract tumour after gallbladder cancer and common bile duct cancer. The incidence of ampullary adenocarcinoma is not well known although it is estimated to be around 0.49 per 100,000 people. The known risk factors are familial adenomatous polyposis (FAP) and Gardner's syndrome, HNPCC (Hereditary Non-Polyposis Colorectal Cancer) syndrome, Peutz-Jeghers syndrome, Crohn's disease and coeliac disease. Except in its highly localised forms, ampulla of Vater carcinoma carries a poor prognosis. It is a highly lymphophilic disease which commonly metastasises, particularly to the lymph nodes and liver. The prognosis is however considerably better than that of pancreatic adenocarcinoma. In one study which compared 71 ampullomas with 144 adenocarcinomas of pancreatic head, the 5-year survival was 60% for the ampullary carcinomas compared to 20% for pancreatic adenocarcinomas. More generally, the 5-year survival rate in the literature is between 40-60% and, depending on the study, 10-year survival is approximately 38% . The only curative treatment is complete excision (surgical or endoscopic) of the lesions which is possible in 80% of cases , with or without adjuvant treatment. The reference radical treatment is cephalic duodenopancreatectomy (CDP). The 5-year survival rate in cases of adenocarcinoma excised by CPD is in the region of 50%, rising to 60-70% if no lymph node invasion is present, compared to 30% when lymph nodes are invaded and median survival is approximately 4.5 years . The indication for adjuvant treatment is still debated: in view of the aggressive nature of the disease and the high recurrence rate, it would appear appropriate to offer adjuvant treatment, although several studies have failed to find any benefit on survival with post-operative radio-chemotherapy, the most widely studied treatment at present, compared to excision alone . There is only one single randomised study comparing these two forms of management, which shows no benefit in terms of 2 and 5-year survival, although only a small number of patients had an ampullary tumour in this study . The conclusions of several retrospective studies are more subtle, showing results in favour of adjuvant treatment in patients with lymph node disease or a large tumour (T3/T4) . Some groups have tested the merits of peroperative irradiation. It would appear that this technique does not improve survival, although data on this subject are extremely patchy . Administration of exclusive adjuvant chemotherapy has been examined in a single randomised study. In this phase III study (ESPAC 3), median overall survival of patients who received adjuvant chemotherapy with FUFOL Mayo for 6 months (n=101) or gemcitabine (n=98) was not significantly improved compared to survival in patients undergoing surgery and not receiving complementary treatment (57.1 versus 43 months, HR= 0.85, p=0.32). A subgroup analysis suggested that the benefit of chemotherapy could be greater in the subgroup of patients with RO resection (p= 0.057, 91% of cases). Mean survival in patients suffering inoperable tumours is between 9 and 20.4 months depending on the study . It should be noted however that most of these studies have included tumours other than ampullomas (particularly small bowel adenocarcinomas), making it more difficult to interpret these results, and also that many are old results dating from before the era of modern chemotherapies. At present there are no phase II studies specifically examining medical treatment of degenerated, inoperable Vater's ampullomas. Some groups propose chemotherapies with 5-FU or gemcitabine, analogous to the treatments used for intestinal, pancreatic or biliary tumours, although neither one has been shown to date to be superior to the other, nor have decision-making criteria been clearly established. One phase II study published in 2009 proposed CAPOX as the reference treatment in light of the promising results obtained. Patients suffering from ampullary cancer in this study however were combined with patients who were suffering from small bowel adenocarcinoma. In conclusion, a national cohort study is proposed to undertake a prospective analysis of the outcome of all patients treated for ampullary adenocarcinoma (particularly survival without recurrence and prognostic indicators for excised tumours and the duration of disease control for tumours treated with palliative chemotherapy). The treatment methods will be left to the free choice of the investigator and all patients may be included, regardless of stage of their disease. In this study, freezing of tumour fragments is encouraged, as this cohort will be supplemented by a later biological study. In order to recruit sufficient patient numbers, the study will be based on participation of the cooperative groups involved in the management of digestive cancers.

Bougie Sleeve Trial

Laparoscopic sleeve gastrectomy (LSG) has become an increasing bariatric procedure. The most common complication is gastric leak from the staple line, observed in approximately 3% of cases, and can result in long and incapacitating treatment. The diameter of the bougie used to calibrate the remnant stomach could impact the rate of gastric leak, a higher diameter being correlated with a lower risk of leak, without lowering long-term weight loss. The aim of this prospective randomized trial is to compare the outcomes of LSG according to the use of a standard care bougie calibre or 48-Fr on postoperative gastric leak and mid-term weight loss.
