Treatment of malignant primary cardiac lymphoma with tumor resection using minimally invasive cardiac surgery.

ABSTRACT: BACKGROUND:Primary cardiac lymphoma (PCL) is extremely rare and progresses rapidly. The treatment of PCL has not yet been established. Unlike lymphoma that arises from other organs, PCL causes cardiovascular events. We report the complete remission (CR) of PCL after tumor resection using minimally invasive cardiac surgery (MICS) and chemotherapy. CASE PRESENTATION:The patient was a 79-year-old man who visited our hospital with chief complaints of weight loss and leg edema. A 40?×?30 mm mobile pedunculated tumor continuous with the right ventricular heart muscle was present in the right atrium upon echocardiography and extended cardiac surgery was difficult to perform. Tumor embolism-induced sudden death was prevented and a pathological diagnosis was obtained by making a 4-cm skin incision, and tumor resection with MICS was performed through a right fourth intercostal thoracotomy with a cardiopulmonary system. The histopathological diagnosis was diffuse large B cell malignant lymphoma. Eight cycles of postoperative rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) therapy were performed. Three years after surgery, the tumor was not visible on imaging and CR was maintained. CONCLUSIONS:This case highlights that tumor resection using MICS is effective for avoiding the risk of sudden death. This technique was useful for the diagnosis and treatment of a malignant cardiac tumor in an elderly patient that required a difficult extended cardiac surgery.

Project description:BackgroundPancreatic resections are among the most technically demanding procedures, including a high risk of potentially life-threatening complications and outcomes strongly correlated to hospital volume and individual surgeon experience. Minimally invasive pancreatic resections (MIPRs) have become a part of standard surgical practice worldwide over the last decade; however, in comparison with other surgical procedures, the implementation of minimally invasive approaches into clinical practice has been rather slow.ObjectiveThe aim of this study was to highlight and summarize the available randomized controlled trials (RCTs) evaluating the role of minimally invasive approaches in pancreatic surgery.MethodsA WHO trial registry and Pubmed database literature search was performed to identify all RCTs comparing MIPRs (robot-assisted and/or laparoscopic distal pancreatectomy [DP] or pancreatoduodenectomy [PD]) with open pancreatic resections (OPRs).ResultsOverall, five RCTs on MIPR versus OPR have been published and seven RCTs are currently recruiting. For DP, the results of two RCTs were in favor of minimally invasive distal pancreatectomy (MIDP) in terms of shorter hospital stay and less intraoperative blood loss, with comparable morbidity and mortality. Regarding PD, two RCTs showed similar advantages for MIPD. However, concerns were raised after the early termination of the third multicenter RCT on MIPD versus open PD due to higher complication-related mortality in the laparoscopic group and no clear other demonstrable advantages. No RCTs on robot-assisted pancreatic procedures are available as yet.ConclusionAt the current level of evidence, MIDP is thought to be safe and feasible, although oncological safety should be further evaluated. Based on the results of the RCTs conducted for PD, MIPD cannot be proclaimed as the superior alternative to open PD, although promising outcomes have been demonstrated by experienced centers. Future studies should provide answers to the role of robotic approaches in pancreatic surgery and aim to identity the subgroups of patients or indications with the greatest benefit of MIPRs.

Project description:IntroductionIntercostal cryo nerve block has been shown to enhance pulmonary function recovery and pain management in post-thoracotomy procedures. However, its benefit have never been demonstrated in minimal invasive thoracotomy heart valve surgery (Mini-HVS). The purpose of the study was to determine whether intraoperative intercostal cryo nerve block in conjunction with standard of care (collectively referred to hereafter as CryoNB) provided superior analgesic efficacy in patients undergoing Mini-HVS compared to standard-of-care (SOC).MethodsFROST was a prospective, 3:1 randomized (CryoNB vs. SOC), multicenter trial in patients undergoing Mini-HVS. The primary endpoint was the 48-h postoperative forced expiratory volume in 1 s (FEV1) result. Secondary endpoints were visual analog scale (VAS) scores for pain at the surgical site and general pain, intensive care unit and hospital length-of-stay, total opioid consumption, and allodynia at 6 months postoperatively.ResultsA total of 84 patients were randomized to the two arms of the trial CryoNB (n = 65) and SOC (n = 19). Baseline Society of Thoracic Surgeons Predictive Risk of Mortality (STS PROM) score, ejection fraction, and FEV1 were similar between cohorts. A higher 48-h postoperative FEV1 result was demonstrated in the CryoNB cohort versus the SOC cohort (1.20 ± 0.46 vs. 0.93 ± 0.43 L; P = 0.02, one-sided two-sample t test). Surgical site VAS scores were similar between the CryoNB and SOC cohorts at all postoperative timepoints evaluated, but VAS scores not related to the surgical site were lower in the SOC group at 72, 94, and 120 h postoperatively. The SOC cohort had a 13% higher opioid consumption than the CryoNB cohort. One of 64 CryoNB patients reported allodynia that did not require pain medication at 10 months.ConclusionsThe results of FROST demonstrated that intercostal CryoNB provided enhanced FEV1 score at 48 h postoperatively with optimized analgesic effectiveness versus SOC. Future larger prospective randomized trials are warranted to determine whether intercostal CryoNB has an opioid-sparing effect in patients undergoing Mini-HVS.Trial registrationClinicaltrials.gov identifier: NCT02922153.
