Lidocaine Decreases Postoperative Lung Cancer Reoccurance and Metatasis Risk

The goal of this clinical trial is to explore if perioperative lidocaine infusion decreases disease reoccurrence and metastasis risk in non-small cell lung cancer patients. Participants will be randomly assigned (1:1) to the lidocaine or placebo group. The intervention initiates within 30 minutes before anesthesia induction with an intravenous loading dose of 1.5 mg/kg administered over 10-20 minutes. This is followed by a continuous maintenance infusion of 1.5-3 mg/kg/h (calculated as 1-1.5 mg/kg/h in protocol text, see note below) during surgery, terminating 1 hour after skin closure. Participants will be followed up for 36 months post-surgery. Blood samples will be collected at baseline, postoperative day 1, day 3, and upon discharge

The Impact of Transjugular Intrahepatic Portosystemic Shunt on Recompensation in Patients With Decompensated Liver Cirrhosis

The traditional view holds that the natural course of cirrhosis is a unidirectional process, characterized by irreversible progression from the compensated stage to the decompensated stage, and is highly likely to develop further decompensation events or even death. However, a growing body of evidence suggests that the natural course of cirrhosis is not always unidirectional - after the removal of the etiology, the structural and functional changes of the liver may be partially reversed. This understanding has given rise to the concept of "liver recompensation," which has been standardized at the Baveno VII Consensus Conference. Notably, in a cohort of patients with alcohol-related cirrhosis, 18% achieved recompensation, which was significantly associated with a reduction of more than 90% in liver-related mortality. In patients with hepatitis B-related cirrhosis, 6% achieved recompensation after treatment with nucleos(t)ide analogs, with a similar improvement in mortality. Transjugular intrahepatic portosystemic shunt (TIPS) is a well-established therapy for complications related to portal hypertension, including gastroesophageal variceal bleeding, refractory ascites, and hepatic hydrothorax. Compared with standard treatment, TIPS has been proven to reduce the incidence of further decompensation and improve transplant-free survival. However, due to portal blood shunting, the risks of abnormal liver function and hepatic encephalopathy (HE) also increase. It is worth noting that TIPS is not included in the definition of recompensation in the Baveno VII Consensus. Therefore, whether patients with cirrhosis who undergo TIPS treatment can achieve recompensation and which factors determine the probability of recompensation remain unknown. More importantly, the impact of recompensation on the risk of HCC development and mortality in TIPS patients has not been studied prospectively.

Evaluation of Intra-operative Photographs for the Assessment of a Proper Lymphadenectomy in Minimally-invasive Gastrectomies for Gastric Cancer (PhotoNodes)

Even after the wide introduction of chemo/radiotherapy in the treatment algorithm, adequate surgery remains the cornerstone of gastric cancer treatment with curative intent. A proper D2 lymphadenectomy is associated with improved cancer specific survival as confirmed in Western countries by fifteen-year follow-up results of Dutch and Italian randomized trials. In clinical practice, the total number of harvested lymph nodes is often considered as a surrogate marker for adequate D2 lymphadenectomy; nonetheless, the number of retrieved nodes does not necessarily correlate with residual nodes, which intuitively could represent a more reliable marker of surgical adequacy. The availability of an efficient tool for evaluating the absence of residual nodes in the operative field at the end of node dissection could better correlate with survival outcomes. The goal of this multicentric observational prospective study is to test the reliability of a new score (PhotoNodes Score) created to rate the quality of the lymphadenectomy performed during minimally invasive gastrectomy for gastric cancer. The score is assigned by assessing the absence of residual nodes at the end of node dissection on a set of laparoscopic/robotic high quality intraoperative images collected from each patient undergoing a minimally invasive gastrectomy with D2 node dissection. Ideally, this tool could be a new indicator of the quality of D2 dissection and could assume a prognostic role in the treatment of gastric cancer.
