- Background: Isolated limb perfusion (ILP) is an established and effective treatment for advanced melanoma and soft tissue sarcomas of the extremities with a high overall response rate. The aim of this study was to describe our experience of ILP for more rare types of tumours. Methods: Patients with Merkel cell carcinoma (MCC) (n = 4), squamous cell carcinoma (SCC) (n = 2), B-cell lymphoma (n = 1), desmoid tumours (n = 3), pigmented villonodular synovitis (PVNS) (n = 1) and giant cell tumour (n = 1) were treated with ILP and analysed retrospectively. Results: The four patients with in-transit MCC had three complete responses (CR) and one partial response (PR); the two patients with SCC had one CR and one stable disease (SD); the patients with desmoid tumours had two PR and one SD. A CR was also observed for the patient with a giant cell tumour, but the patient with PVNS had a SD. The patient with cutaneous metastases of B-cell lymphoma showed a CR, however with rapid systemic progression. Local toxicity according to Wieberdink was grade II in 10 patients (83%) and grade III in two patients (17%). Conclusions: These results show that ILP can be used as a treatment option also for more rare disease entities when other treatments have failed.

- INTRODUCTION: Few studies have reported the characteristics of patients with in-hospital stroke (IHS) including the reason for hospitalization and invasive procedures before the stroke. We aimed to extend current knowledge.PATIENTS AND METHODS: All adult patients with IHS in Sweden during 2010-2019 registered in the Swedish Stroke Register (Riksstroke) were included. The cohort was cross-linked to the National Patient Register and data extracted on background diagnoses, main discharge diagnoses, and procedure codes for the hospitalization when IHS occurred and any hospital-based healthcare contacts within 30 days before IHS.RESULTS: 231,402 stroke cases were identified of which 12,551 (5.4%) were in-hospital and had corresponding entries in the National Patient Register. Of the IHS patients, 11,420 (91.0%) had ischemic stroke and 1131 (9.0%) hemorrhagic stroke; 5860 (46.7%) of the IHS patients had at least one invasive procedure prior to ictus. 1696 (13.5%) had a cardiovascular procedure and 560 (4.5%) a neurosurgical procedure. 1319 (10.5%) patients only had minimally invasive procedures such as blood product transfusion, hemodialysis, or central line insertion. Common discharge diagnosis in patients with no invasive procedures were cardiovascular disorders, injuries, and respiratory disorders.DISCUSSION AND CONCLUSION: One in every 17 strokes in Sweden occur in a hospital. In this unselected large cohort the previously reported major causes for in-hospital stroke, cardiovascular and neurosurgical procedures, preceded IHS in only 18.0% of cases suggesting that other etiologies are more common than previously reported. Future studies should aim at determining absolute risks of stroke after surgical procedures and ways of risk reduction.

- Isolated hepatic perfusion (IHP) is a procedure where the liver is surgically isolated and perfused with a high concentration of the chemotherapeutic agent melphalan. Briefly, the procedure starts with the setup of a percutaneous veno-venous bypass from the femoral vein to the external jugular vein. Via a laparotomy, catheters are then inserted into the proper hepatic artery and the caval vein. The portal vein and the caval vein, both supra- and infrahepatically, are then clamped. The arterial and venous catheters are connected to a heart lung machine and the liver is perfused with melphalan (1 mg/kg body weight) for 60 min. This way it is possible to locally perfuse the liver with a high dose of a chemotherapeutic agent, without leakage to the systemic circulation. In previous studies including patients with isolated liver metastases of uveal melanoma, an overall response rate of 33-100% and a median survival between 9 and 13 months, have been reported. The aim of this protocol is to give a clear description of how to perform the procedure and to discuss IHP as a treatment option for liver metastases of uveal melanoma.

- Background: Isolated hepatic perfusion (IHP) is a treatment option for patients with liver metastases. Previous studies have found that liver toxicity is one of the limiting factors, and in an attempt to reduce the toxicity a buffering agent was added to the perfusate. The aim was to retrospectively analyse if this buffering reduced toxicity and complication rates.Methods: A retrospective review of 52 consecutive patients with uveal melanoma liver metastases treated with IHP between 2005 and 2013. Patients were followed by daily liver function tests (LFT). Toxicity was graded according to Common Terminology Criteria for Adverse Events version 4.0 (CTCAE; United States Department of Health & Human Services, Washington, D.C), complications according to Clavien-Dindo and response according to RECIST-criteria.Results: Thirty-six patients were treated with a buffered perfusate and 16 patients without buffer. There was no difference in age, gender, largest tumour size or number of tumours between the groups. There was a significantly lower mean in peak ALT, AST, PK (INR) and bilirubin when comparing buffer with no-buffer. There were five major complications without a significant difference between the groups (8.3 vs. 12.5%, p=0.33). There was a lower complete response (CR) rate (11 vs. 44%, p=0.023) and a trend for shorter time to local progression (9.2 vs. 17.6 months, p=0.096); however, not significant in multivariate analysis. There was no difference in survival (24.2 vs. 26.0 months, p=0.43) between the two groups.Conclusions: Adding buffer to the perfusate during IHP significantly reduces postoperative LFTs; however, without a reduced complication rate. Interestingly, buffering also seems to reduce the response rate; however, this did not translate into a survival difference. To address if buffering adds any clinical benefit to the patients concerning toxicity, a larger prospective trial is necessary.

- Isolated limb perfusion (ILP) and infusion (ILI) are therapeutic modalities for the treatment of in transit melanoma. A retrospective review of all patients undergoing first-time ILI or ILP for in-transit melanoma metastases between 2007 and 2015 was performed. Demographic and clinical characteristics included age, sex, nodal status at the time of ILI/ILP (N-stage), and burden of disease (BOD). Regional toxicity was categorized by the Wieberdink classification. Clinical response was evaluated at 3 months after treatment. A total of 203 patients were reviewed (ILI = 94, ILP = 109). There were no differences in age, sex, or N-stage between groups; however, BOD was higher for the ILI group (high BOD 58 vs. 44 %, p = 0.04). Regional toxicity was minimal (Grade IV < 1 % in ILI and 2 % in ILP, p = 0.40). Overall response rate (ORR) was 53 % for ILI versus 80 % for ILP (p < 0.001). Median overall survival (OS) was 46 months for ILI versus 40 months for ILP (p = 0.31). A high BOD [hazard ratio (HR) 3.02, 95 % confidence interval (CI) 1.85-4.93, p < 0.001] and N3 disease (HR 1.58, 95 % CI 1.01-2.48, p = 0.04) were associated with worse OS, whereas there was no difference in OS by procedure (p = 0.20). ILP offers an improved ORR, but this does not translate into improved local PFS or OS. Both procedures are well tolerated with minimal regional toxicity.

- Isolated limb perfusion (ILP) is used to treat in-transit metastases of melanoma of the extremities when surgical excision is not possible. The optimal setting concerning temperature and perfusion time is unknown. The purpose of this study was to analyze these factors concerning their effects on response, toxicity, and survival. A retrospective analysis of 284 consecutive stage III melanoma patients treated with melphalan ILP for the first time in our institution, during a 31-year period (July 1986-May 2017), was performed. Our series was divided in four time periods, according to perfusion temperature and duration. Demographical data, stage, number, and size of lesions were retrieved from our prospective database. Overall response (OR) rate 83% and a complete response (CR) rate of 59%. Significant predictive factors for CR in multivariate analysis were non-bulky tumor, fewer metastases, and a perfusion time of 120 min. Predictive factors for increased local toxicity were femoral ILP and higher perfusion temperatures. The median overall survival was 30 months, and the independent negative prognostic factors were lymph-node status, bulky tumors, response, upper limb perfusion, and 120 min perfusion at 39-40 A degrees C. Modern ILP uses diminished perfusion time and lower temperature, leading to a decrease in toxicity. However, our data also show a decrease in response, which indicates that optimal perfusion time and temperature regimen remain to be determined.

- The incidence of malignant melanoma is increasing, and up to 5 % of patients will experience in-transit metastases. Normally, the initial treatment is surgical excision, but when not possible, locoregional treatment options such as isolated limb perfusion (ILP) are an alternative. This study aimed to assess health-related quality of life (HRQoL) prospectively for patients whose in-transit metastases is treated with ILP. More specifically, the study aimed to describe HRQoL for patients with in-transit extremity melanoma metastases, to describe changes in HRQoL after ILP, and to correlate HRQoL with local toxicity and clinical response after ILP. The Functional Assessment of Cancer Therapy-Melanoma (FACT-M) consists of 51 items comprising the Functional Assessment of Cancer Therapy-General (FACT-G), the melanoma subscale , and the melanoma surgery scale. Forty-five patients answered the FACT-M questionnaire before ILP (52 procedures) and at 3, 6 and 12 months after ILP. Response and toxicity were analyzed and correlated with the changes in the HRQoL of the patients. Patients with in-transit metastasis have an HRQoL mainly influenced by tumor burden, defined as more or < 10 tumors (FACT-M: 142.5 vs. 128.4 points; p = 0.02). After ILP, there was a trend toward a decrease in FACT-G (+0.1 vs. -7.3 points; p = 0.05) and FACT-M (+1.6 vs. -8.9 points; p = 0.08) when Wieberdink classifications 1-2 and 3-4 were compared at 3 months. A significant difference in FACT-G (+1.0 vs. -13.0 points; p = 0.04) was observed 12 months after ILP as well as a trend for FACT-M (+1.7 vs. -14.6 points; p = 0.08) when the patients who had a complete response were compared with those who did not. This study found that patients with in-transit metastases have an HRQoL mainly influenced by tumor burden. After ILP, there is an initial decrease in HRQoL due to local toxicity. After 12 months, the patients with a complete response maintained an HRQoL at baseline level, strengthening the use of ILP as a palliative treatment.
