Thoracoabdominal normothermic regional perfusion has emerged as an alternative method to procure donation after circulatory death (DCD) hearts, but its impact on concomitantly procured lung allografts remains unclear. The United Network for Organ Sharing database identified 627 DCD donors whose hearts were procured (211 in situ perfused, 416 directly procured) between December 2019 to December 2022. Lung utilization rates were 14.9% (63/422) for in situ perfused donors and 13.8% (115/832) for directly procured donors (p = 0.80). Following transplantation, lung recipients from in situ perfused donors required numerically lower rates of extracorporeal membrane oxygenation (7.7% vs 17.0%, p = 0.26) and mechanical ventilation (34.6% vs 47.2%, p = 0.29) at 72 hours. Six-month post-transplant survival was similar between groups (85.7% vs 89.1%, p = 0.67). These results suggest that the use of thoracoabdominal normothermic regional perfusion in DCD heart procurement may not adversely impact recipients of concomitantly procured lung allografts.

BackgroundWhile parenchymal hepatic metastases were previously considered a contraindication to cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC), liver resection (LR) is increasingly performed with CRS/HIPEC.MethodsPatients from the US HIPEC Collaborative (2000-2017) with invasive appendiceal or colorectal adenocarcinoma undergoing primary, curative intent CRS/HIPEC with CC0-1 resection were included. LR was defined as a formal parenchymal resection. Primary endpoints were postoperative complications and overall survival (OS).ResultsA total of 658 patients were included. About 83 (15%) underwent LR of colorectal (58%) or invasive appendiceal (42%) metastases. LR patients had more complications (81% vs. 60%; p = .001), greater number of complications (2.3 vs. 1.5; p

Simple Summary: Every year lung cancer takes the lives of many patients, making it the most common cause of cancer-related deaths. While surgery is the gold standard treatment for early-stage lung cancer, its share in treating more advanced disease stages is limited. Therefore, clinicians advise a multimodal treatment consisting of chemotherapy, radiotherapy and/or immunotherapy to treat advanced lung cancers. There has been a growing interest in loco-regional techniques as they are expected to have advantages over current therapies. In this article, we provide an overview of the established and promising innovative invasive loco-regional techniques ordered by their route of administration (endobronchial, endovascular and transthoracic route) and an overview of their implementation and effectiveness. Although the results of these techniques show improved local disease control and effect, there is a need for more clinical studies to guarantee their efficacy and safety before they can be used within the clinic. Surgical resection is still the standard treatment for early-stage lung cancer. A multimodal treatment consisting of chemotherapy, radiotherapy and/or immunotherapy is advised for more advanced disease stages (stages IIb, III and IV). The role of surgery in these stages is limited to very specific indications. Regional treatment techniques are being introduced at a high speed because of improved technology and their possible advantages over traditional surgery. This review includes an overview of established and promising innovative invasive loco-regional techniques stratified based on the route of administration, including endobronchial, endovascular and transthoracic routes, a discussion of the results for each method, and an overview of their implementation and effectiveness.

BackgroundPatient selection for cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is critically important to optimizing outcomes. There is currently no literature regarding the safety of CRS/HIPEC in patients with cirrhosis. The aim of this case series is to report the outcomes of three patients with well-compensated cirrhosis who underwent CRS/HIPEC.MethodsPatients were identified from a prospectively maintained peritoneal surface malignancy database. Patient, tumor, and operative-related details were recorded as short-term postoperative outcomes. Results were analyzed using descriptive statistics.ResultsAll patients had well-compensated (Child-Pugh Class A) cirrhosis and Eastern Cooperative Oncology Group (ECOG) performance status of 0. One patient had preoperative evidence of portal hypertension. All safely underwent CRS/HIPEC with completeness of cytoreduction (CC) scores of 0. The postoperative morbidity profile was unique, but all complications were manageable and resulted in full recovery to preoperative baseline status.ConclusionsPatient selection for CRS/HIPEC is critical for optimization of short- and long-term outcomes. This small series suggests that well-compensated cirrhosis should not be an absolute contraindication to CRS/HIPEC.

To investigate the effect and mechanism of ANA-12 on relieving oxaliplatin (OXA) induced neuropathic pain by targeting brain-derived neurotrophic factor (BDNF)/tyrosine kinase receptor B (TrkB) signaling in rats. Methods Eighteen male SD rats were randomly divided into 3 groups according to table of random number: the control group, the OXA treated group and the OXA + ANA-12 group (OXA+ANA-12), with 6 rats in each group. The OXA group and the OXA + ANA-12 group received an intraperitoneal injection of OXA (4 mg/kg for 5 days) to construct a chemotherapeutic pain model. After the model was successfully established, ANA-12 (20 g/L) was intrathecally administered in the OXA + ANA-12 group. After administration, pain behavior tests of rats in each group were performed, and changes in number of spontaneous flinches and mechanical pain threshold were recorded. The infiltration of spinal inflammatory cells and changes in expression level of interleukin (IL)-1β, tumor necrosis factor (TNF)-α, ionized calcium binding adapter molecule 1 (Iba1), BDNF, TrkB and nuclear factor kappa B (NF-κB) were detected by HE staining, immunofluorescence and Western blot assay. Results Compared with the control group, behavioral analysis showed that continuous injection of OXA significantly induced pain hyperalgesia and increased number of spontaneous flinches. Compared with the OXA group, intrathecal injection of ANA-12 significantly decreased the number of spontaneous flinches and increased mechanical pain threshold of rats. Morphological and protein expression analysis showed that OXA administration induced spinal inflammation, up-regulated BDNF/TrkB signaling and increased the expression levels of IL-1β, TNF-α, Iba1 and NF-κB compared with those of the control group. Compared with the OXA group, ANA-12 treatment significantly inhibited BDNF/ TrkB signaling and down-regulated the expression levels of IL-1β, TNF-α, Iba1 and NF-κB. Conclusion Intrathecal administration of ANA-12 inhibits spinal inflammation and relieves chemotherapy pain by blocking BDNF/TrkB signal. [ABSTRACT FROM AUTHOR]

BackgroundCytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) has an emerging role in the treatment of peritoneal malignancies. The CRS-HIPEC approach has known treatment-related toxicities. This study sought to determine the predictors of major postoperative complications after CRS-HIPEC in a high-volume center.MethodsFrom a single-institution database, this study investigated complications experienced by patients undergoing CRS-HIPEC. Multiple preoperative and operative factors were analyzed for their ability to predict 60-day Clavien grade 3 and greater (major) complications by logistic regression. A predictive model was created from preoperative factors using multivariate logistic regression. The model was tested by Akaike's information criterion, the Hosmer and Lemeshow Goodness-of-Fit Test, the receiver operating characteristic, and the Youden Index.ResultsThe study evaluated 247 patients undergoing CRS-HIPEC. The primary tumor site was the appendix in 166 cases (67.2 %), the colorectal area in 51 cases (20.6 %), the peritoneum (mesothelioma) in 22 cases (8.9 %), the ovary in 5 cases (2 %), and the small bowel in 3 cases (1.2 %). The median peritoneal cancer index was 14 (range 0-29), and 235 patients (95.1 %) had a complete (CC-0/1) cytoreduction. Major complications occurred for 41 patients (16.6 %), classified as grade 3 in 33 cases (13.4 %), grade 4 in 5 cases (2 %), and grade 5 (deaths) in 3 cases (1.2 %). The factors predictive of major complications in the multivariate analysis were a Charlson Comorbidity Index (CCI) score higher than 0 [odds ratio (OR), 2.505; p = 0.035], presence of preoperative symptoms (OR 1.951; p = 0.064), and prior resection status [no resection or prior CRS-HIPEC (OR 2.087) vs. prior resection without CRS-HIPEC (OR 3.209); p = 0.046]. These variables were used to create a tool predictive of postoperative complications.ConclusionPresence of symptoms, CCI, and prior resection status predict major complications and define a low-risk population after CRS-HIPEC.

Patient: Male, 67-year-old Final Diagnosis: Pancreatic moderately differentiated tubular metastatic adenocarcinoma Symptoms: Abdominal pain-ascites Medication: -- Clinical Procedure: Pressurized Intraperitoneal Aerosol Chemotherapy (PIPAC) Specialty: Oncology Surgery Objective: Unusual setting of medical care Background: Peritoneal metastasis is a common progression of abdominal-pelvic cancers, and it is associated with poorer oncological prognosis when compared to other metastasis sites. Its treatment has limited results, mainly because of poor bioavailability of chemotherapy within the abdominal cavity after systemic administration. Pressurized intraperitoneal aerosol chemotherapy (PIPAC) has been proposed as a novel method to deliver chemotherapy directly into the peritoneal surface; it combines the effectiveness and response of an intraperitoneal therapy with benefits of a minimally invasive approach. The laparoscopic capnoperitoneum is used to instill chemotherapy particles in a more efficient way for distribution and penetration when compared to peritoneal lavage. In the present study, we describe the first PIPAC performed in Brazil, according to the standard technique previously described with the Capnopen® nebulizer device, as well as technique details based on our literature review. Case Report: A 67-year-old man with pancreatic adenocarcinoma metastatic to the liver at first diagnosis underwent systemic treatment with the FOLFIRINOX protocol. After a major clinical response due to systemic treatment, pancreaticoduodenectomy was performed with resection and radiofrequency ablation of hepatic nodules. After 7 months of follow-up, the patient's condition evolved with symptomatic relapse in the peritoneum. Aiming at better control of this site, multiple PIPAC procedures were performed, showing excellent control of the peritoneal cavity disease. The patient had a sustained response in the peritoneal cavity and showed systemic disease progression 6 months after the first PIPAC procedure, which deceased at 20 months after the first PIPAC procedure and 42 months after the primary diagnosis. Conclusions: This report shows that the PIPAC procedure is reproducible elsewhere, with safety and good functional results. [ABSTRACT FROM AUTHOR]

Summary: In donation after circulatory death (DCD), (thoraco)abdominal regional perfusion (RP) restores circulation to a region of the body following death declaration. We systematically reviewed outcomes of solid organ transplantation after RP by searching PubMed, Embase, and Cochrane libraries. Eighty‐eight articles reporting on outcomes of liver, kidney, pancreas, heart, and lung transplants or donor/organ utilization were identified. Meta‐analyses were conducted when possible. Methodological quality was assessed using National Institutes of Health (NIH)‐scoring tools. Case reports (13/88), case series (44/88), retrospective cohort studies (35/88), retrospective matched cohort studies (5/88), and case‐control studies (2/88) were identified, with overall fair quality. As blood viscosity and rheology change below 20 °C, studies were grouped as hypothermic (HRP, ≤20 °C) or normothermic (NRP, >20 °C) regional perfusion. Data demonstrate that RP is a safe alternative to in situ cold preservation (ISP) in uncontrolled and controlled DCDs. The scarce HRP data are from before 2005. NRP appears to reduce post‐transplant complications, especially biliary complications in controlled DCD livers, compared with ISP. Comparisons for kidney and pancreas with ISP are needed but there is no evidence that NRP is detrimental. Additional data on NRP in thoracic organs are needed. Whether RP increases donor or organ utilization needs further research. [ABSTRACT FROM AUTHOR]

Large unresectable STS presents a therapeutic challenge. Several options are being explored to avoid amputation without compromising the oncological outcome. Neoadjuvant chemotherapy delivers inconsistent and rather unsatisfactory results, preoperative radiotherapy compromises healing, hence it can impede adjuvant systemic treatment. We present a case report of neoadjuvant use of isolated limb perfusion with TNF-alfa and Alkeran (Melphalan) in a patient with initially unresectable large myxoid liposarcoma of the thigh. We achieved 55% reduction in size of the tumor that allowed for wide resection with a safe margin. Pathology confirmed 99% tumor necrosis. The patient has a full function of his extremity and is disease-free at one year follow-up. ILP should be considered as a treatment option which, in selected cases, can contribute to limb sparing surgery. [ABSTRACT FROM AUTHOR]

ImportanceHyperthermic intraperitoneal chemotherapy (HIPEC) and cytoreductive surgery have been shown to benefit selected patients with peritoneal carcinomatosis. However, these procedures are associated with high morbidity and mortality. Available data investigating the outcomes of HIPEC are mostly limited to single-center studies. To date, there have been few large-scale studies investigating the postoperative outcomes of HIPEC.ObjectiveTo determine the associated 30-day morbidity and mortality of cytoreductive surgery-HIPEC in the treatment of metastatic and primary peritoneal cancer in American College of Surgeons National Surgical Quality Improvement Program centers.Design, setting, and participantsA retrospective review of HIPEC cases performed for primary and metastatic peritoneal cancer diagnoses was conducted. The cytoreductive surgical procedures were sampled, and disease processes were identified. Patient demographics, intraoperative occurrences, and postoperative complications were reviewed from the American College of Surgeons National Surgical Quality Improvement Program from 2005-2011.Main outcomes and measuresThirty-day mortality and morbidity.ResultsOf the cancers identified among the 694 sampled cases, 14% of patients had appendiceal cancer, 11% had primary peritoneal cancer, and 8% had colorectal cancer. The American Society of Anesthesiologists classification was 3 for 70% of patients. The average operative time was 7.6 hours, with 15% of patients requiring intraoperative transfusions. Postoperative bleeding (17%), septic shock (16%), pulmonary complications (15%), and organ-space infections (9%) were the most prevalent postoperative complications. The average length of stay was 13 days, with a 30-day readmission rate of 11%. The rate of reoperation was 10%, with an overall mortality rate of 2%.Conclusions and relevanceAmerican College of Surgeons National Surgical Quality Improvement Program hospitals performing HIPEC have acceptable rates of morbidity and mortality.

Abstract Background Chemoradiotherapy has a dominant role in therapy for head and neck cancers. However, impressive results are often disturbed by adverse events such as dysphagia, xerostomia, and functional speech and hearing loss. To avoid exceeding toxicity limits in patients with primary and recurrent cancers of the tonsils, chemotherapy was administered intra-arterially via implantable Jet-Port-Allround catheters. Methods We report on patients with primary and recurrent cancers of the tonsils. Eleven patients who refused chemoradiation were included in this trial. Of the seven patients without prior therapy, one was stage I, one was stage III, three were stage IVA, one was stage IVB, and one was stage IVC. The four patients who were in progression after prior chemoradiation were stage IVA. The median follow-up time was 47 months (20 to 125 months). After the implantation of a Jet-Port-Allround catheter into the carotid artery, the patients received intra-arterial infusion chemotherapy with venous chemofiltration for systemic detoxification. The stage I patient received lower-dose chemotherapy without chemofiltration. The stage IVC patient with lung metastases and a primary tumor that extended across the midline to the contralateral tonsil received additional isolated thoracic perfusion chemotherapy. Results All seven chemoradiation-naïve patients exhibited clinically complete responses and are still alive after 20 to 125 months. Among the four patients who had relapsed after prior chemoradiation, the intra-arterial therapy elicited only poor responses, and the median survival time was 7.5 months. After carotid artery infusion chemotherapy, none of the patients required tube feeding. No cases of dysphagia, xerostomia, or functional speech and hearing loss have been reported among the patients without prior chemoradiotherapy. Conclusion Despite the administration of low total dosages, intra-arterial infusion generates high concentrations of chemotherapeutics. In combination with chemofiltration, the systemic toxicity is kept within acceptable limits. Among the non-pretreated patients, better tumor responses and long-term tumor control were noted compared with those who had prior chemoradiation. Implantable Jet-Port-Allround carotid artery catheters facilitate the application of regional chemotherapy.

To explore the effects of two different administration routes of Endostar on the survival of patients with medium and advanced hepatocellular carcinoma (HCC) and underwent trans-arterial chemoembolization (TACE). Seventy-two patients with medium and advanced HCC were enrolled. Among them, 42 patients underwent the hepatic arterial infusion of Endostar combined with TACE (infusion therapy group); and the remaining 30 patients underwent the hepatic treatment of TACE combined with the intravenous application of Endostar (intravenous therapy group). All patients underwent regular examinations of CT (or MRI) and DSA to observe the conditions of tumor recurrence or metastasis, and to determine the existence of tumor angiogenesis. The response rate of treatment in the Endostar hepatic arterial infusion group was higher than that in the control group, and the difference was statistically significant (31/42:14/30, X 2 = 5.501, p < 0.05). In addition, median progression free-survival time of the two groups were 8.67 months and 6.67 months, respectively (p = 0.046); and the difference was statistically significant. The hepatic arterial infusion of Endostar combined with TACE can significantly improve recent clinical efficacy and mPFS in the treatment of medium and advanced HCC. However, improvement on the overall survival of long-term efficacy is not significant. [ABSTRACT FROM AUTHOR]

Summary: Livers from donation after circulatory death (DCD) donors are an increasingly more common source of organs for transplantation. While there are few high‐level studies in the field of DCD liver transplantation, clinical practice has undergone progressive changes during the past decade, in particular due to mounting use of postmortem normothermic regional perfusion (NRP). In Spain, uncontrolled DCD has been performed since the late 1980s/early 1990s, while controlled DCD was implemented nationally in 2012. Since 2012, the rise in DCD liver transplant activity in Spain has been considerable, and the great majority of DCD livers transplanted in Spain today are recovered with NRP. A panel of the Spanish Liver Transplantation Society was convened in 2018 to evaluate current evidence and accumulated experience in DCD liver transplantation, in particular addressing issues related to DCD liver evaluation, acceptance criteria, and recovery as well as recipient selection and postoperative management. This panel has created a series of consensus statements for the standard of practice in Spain and has published these statements with the hope they might help guide other groups interested in implementing new forms of DCD liver transplantation and/or introducing NRP into their clinical practices.

Summary: Organ preservation and re‐conditioning using machine perfusion technologies continue to generate promising results in terms of viability assessment, organ utilization and improved initial graft function. Here, we summarize the latest findings and study the results of ex‐vivo/ex‐situ hypothermic (HMP) and normothermic machine perfusion (NMP) in the area of abdominal organ transplantation (kidney, liver, pancreas and intestine). We also consider the potential role of normothermic regional perfusion (NRP) to re‐condition donors after circulatory death organs before retrieval. The findings from clinical studies reported to date suggest that machine perfusion will offer real benefits when compared with conventional cold preservation. Several randomized trials are expected to report their findings within the next 2 years which may shed light on the relative merits of different perfusion methods and could indicate which perfusion parameters may be most useful to predict organ quality and viability. Further work is needed to identify composite endpoints that are relevant for transplanted organs that have undergone machine preservation. Multi‐centre trials to compare and analyse the combinations of NRP followed by HMP and/or NMP, either directly after organ retrieval using transportable devices or when back‐to‐base, are needed. The potential applications of machine preservation technology beyond the field of solid organ transplantation are also considered.

Introduction: To study the anatomical features and classification of the angle between the right gastroepiploic vein (RGEV) and superior mesenteric vein/portal vein (SMV/PV) and to guide the catheterization of intraportal infusion chemotherapy through RGEV and reduce surgical complications.Patients and Methods: A retrospective three-dimensional (3D) computed tomography study was undertaken on 200 consecutive subjects with or without hepatic malignant tumors with a dedicated workstation 3D-MIA (the improved MI-3DVS workstation) developed by ourselves to determine the prevalence of surgically significant angle between RGEV and SMV/PV anatomic variations and its classification.Results: The mean value of the angles between the end of RGEV and SMV/PV (AERS/P) (200 cases) was 84.2° ± 23.8 (31.4°-151.5°): 40.6° ± 92.3 (-177.9° to 178.0°) (sagittal angle), 81.7° ± 29.8 (-79.3° to 160.7°) (coronal angle), and 10.5° ± 94.3 (-178.7° to 175.8°) (horizontal angle). The mean value of the angles between the right bend of RGEV and SMV/PV (ARRS/P) (168 cases) was 104.8° ± 26.1 (20.5°-159.7°):49.3° ± 117.8 (-175.3° to 179.5°) (sagittal angle), 103.5° ± 37.7 (-178.8° to 168.9°) (coronal angle), and 12.6° ± 102.8 (-179.9° to 179.2°) (horizontal angle). The AERS/P were classified into large angle group (32 cases, 16%), middle angle group (113 cases, 56.5%), and small angle group (55 cases, 27.5%) based on angle variations and risks of catheterization.Conclusions: Precognition of the variations of AERS/P and ARRS/P before surgery is useful during chemotherapy pump catheterizing through RGEV in reduction of surgical complications by modulating the angle and direction of RGEV running into SMV/PV properly.

Objective To assess value of immediate postoperative intravesical instillation of pirarubicin after transurethral resection (TURBT)of non-muscle invasive bladder cancer. Methods 484 patients diagnosed with non-muscle-invasive bladder cancer admitted to the Second Affiliated Hospital of Kunming Medical University were divided into two groups after transurethral resection of bladder tumor. 285 patients received postoperative intravesical instillation of pirarubicin within 6 hours after the surgery, 199 patients received first instillation of pirarubicin at 10 days after the surgery, after that, all the patients received routine bladder perfusion chemotherapy. Patients who received intravesical instillation of pirarubicin within 6 hours were defined as immediate intravesical instillation group and the other patients as the control group. Based on the European Organisation for Research and Treatment of Cancer risk tables, scores of recurrence and progression of patients were calculated and then stratified into risk groups accordingly. Recurrence and progression rates of the immediate intravesical instillation group were analyzed and then compared with the corresponding reference of the risk tables. Results The 1-year and 5-year recurrence rate of patients with EORTC table scoring 0 in the immediate intravesical instillation group were significantly lower than that of the EORTC reference group (5.3% and 14.0% vs 15.0% and 31.0%, P<0.05). 1-year recurrence free rate between the immediate intravesical instillation group and the control group in patients scoring 1-4 was significantly different (81.3% vs 76.7%, P=0.014). However, 1-year recurrence free rate of the immediate intravesical instillation group was comparable with that of the control group in patients scoring 5-9, 10-17(P>0.05), which is quite close to the EORTC reference. The probability rates of 1-year and 5-year progression of the 285 patients who received immediate intravesical instillation group did not show significant difference with the EORTC reference. On multivariate analysis, previous recurrence, tumor grade G2-3, tumor multiplicity, delay of immediate intravesical instillation were independent risk factors of recurrence(P<0.05). Conclusions With the help of EORTC recurrence risk table stratifying the patients into different risk groups, our study showed that delay of immediate postoperative intravesical instillation of chemotherapy after TURBT was an independent risk factor of post-surgery recurrence of tumor. Moreover, patients with EORTC scoring 1-4 might obtain greatest benefits. [ABSTRACT FROM AUTHOR]

Foot infections are a common problem among seabirds in wildlife rehabilitation. Pododermatitis and digital infections are often challenging to treat because of the presence of suboptimal substrates, abnormal weight-bearing due to injuries, and suboptimal nutritional or health status. Seabirds represent the majority of animals requiring rehabilitation after oil spills, and foot problems are a common reason for euthanasia among these birds. Antibiotic intravenous regional perfusion therapy is frequently used in humans and other species to treat infections of the distal extremities, but it has not been evaluated in seabirds. During the 2015 Refugio oil spill response, four birds with foot lesions (pododermatitis, osteomyelitis, or both) were treated with ampicillin/sulbactam administered intravenously to the affected limb(s) in addition to systemic antibiotics and anti-inflammatories. Three of the birds, all brown pelicans ( Pelecanus occidentalis) recovered rapidly and were released. Two of these birds had acute pododermatitis and were treated once with intravenous regional perfusion. They were released approximately 3 wk after the perfusion therapy. The third pelican had osteomyelitis of a digit. It was treated twice with intravenous regional perfusion and was released about 1 mo after the initial perfusion therapy. The fourth bird, a Pacific loon ( Gavia pacifica), was treated once with perfusion therapy but did not respond to treatment and was euthanatized. No serious adverse effects were observed. This technique should be explored further in avian species. [ABSTRACT FROM AUTHOR]

Objective To investigate the clinical effect and safety of hepatic arterial infusion of cinobufotalin injection combined with lipiodol chemoembolization ( TACE) in the treatment of Barcelona Clinic Liver Cancer( BCLC) stage C primary liver cancer.Methods A retrospective analysis was performed for the clinical data of 82 patients with BCLC stage C primary liver cancer who were admitted to Department of TCM Oncology in Changhai Hospital from December 2010 to October 2014. According to intraoperative medication, the patients were divided into two groups.The 40 patients in the cinobufotalin group were treated with hepatic arterial infusion with cinobufotalin combined with lipiodol embolism, and the 42 patients in the control group underwent TACE with epirubicin. The objective response rate, time to progression, median survival time, and acute adverse events were compared between the two groups after a single treatment. The t- test was used for comparison of continuous data between groups, the chi- square test was used for comparison of categorical data between groups, and the Kaplan- Meier method was used for the analysis of cumulative survival rate.Results At 1.5 months after surgery, the cinobufotalin group had a significantly higher objective response rate than the control group( 27.5% vs 9.52%, χ~2= 4.429, P = 0.035). The time to progression was 2.4 months( 95% CI:1.978- 2.822) in the cinobufotalin group and 3.0 months( 95% CI:2.260- 3.740) in the control group, and there was no significant difference between the two groups( P = 0.344). The median survival time was 6.6 months( 95% CI:4.131-9.069) in the cinobufotalin group and 10.3 months( 95% CI:0.089- 20.511) in the control group, and there was no significant difference between the two groups( P = 0.132).At 5 days after surgery, the cinobufotalin group had significantly lower incidence rates of abnormal alanine aminotransferase level, white blood cell count, and platelet count, as well as adverse events including hepatalgia, abdominal distension, and nausea/vomiting than the control group( χ~2= 6.193, 5.311, 6.096, 5.909, 4.761, and 4.173, all P < 0.05).Conclusion As for patients with BCLC stage C primary liver cancer, hepatic arterial infusion of cinobufotalin injection combined with lipiodol chemoembolization has a better short- term therapeutic effect, milder adverse effects, and a similar long- term therapeutic effect compared with TACE with conventional chemotherapeutic agents.

Aims: Several classification systems are used for pseudomyxoma peritonei. The four-tiered classification system proposed by Peritoneal Surface Oncology Group International (PSOGI) and the two-tiered proposed by the eighth edition of the American Joint Committee on Cancer (AJCC) result from evolution in terminology and pathological insight. The aim is to evaluate the impact of PSOGI and eighth edition of the AJCC classifications on survival., Methods: Pathological slides were reviewed from a prospectively maintained database including patients treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for an appendiceal mucinous neoplasm with peritoneal dissemination between January 2009 and December 2019. Patients were reclassified according to PSOGI and AJCC eighth edition criteria. Survival analysis evaluated the impact of each classification system on overall survival (OS) and disease-free survival (DFS) while the concordance-index evaluated their predictive power., Results: 95 patients were identified; 21.1% were reclassified as acellular mucin, 55.8% as low-grade mucinous carcinoma peritonei, 8.4% as high-grade MCP (HGMCP) and 14 as HGMCP with signet ring cells. Median OS was not reached, 5-year OS and DFS were 86.1% and 51.5%, respectively. Multivariate analysis revealed significant associations with OS (PSOGI: HR 10.2, p=0.039; AJCC: HR 7.7, p=0.002) and DFS (PSOGI: HR 12.7, p=0.001; AJCC: HR 3.7, p<0.001). The predictive capacity of both classification systems was unacceptable for OS and DFS (concordance-index values <0.7)., Conclusions: Both classification systems behaved similarly when stratifying our series into prognostic groups. The PSOGI classification provides better histopathological description, but histology alone is insufficient for adequate patient prognostication., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Surgical repair of the descending and thoracoabdominal aorta is regularly performed with the support of extracorporeal circulation. Femoral artery cannulation is the standard for arterial inflow, but presents, along with extremity hypoperfusion, the risk of embolization and malperfusion with retrograde aortic perfusion. There are alternatives for arterial inflow to avoid the drawbacks of the standard approach while accommodating different perfusion strategies. Ideally, with a broadened perfusion armamentarium, the choice of arterial inflow could be individualized to provide safe and efficient extracorporeal circulation. [ABSTRACT FROM AUTHOR]
