Complex pathologies involving the aortic arch can be treated using the frozen elephant trunk (FET) technique, which is versatile and continues to be improved with different innovations to further reduce, for example, circulatory arrest time and the need for hypothermia. FET may or may not be a definitive repair, however. Distal extension or completion-especially endovascular-is common but not well described in the literature. This review describes the considerations that are necessary during FET planning and preparation, how pathology specifics and sizing decisions will affect the subsequent need for treatment, and how outcomes might be better reported to improve understanding of the advantages and limitations of the technique.This literature review was performed to identify reports of second-stage endovascular completion after FET repair, and included any literature that described such interventions after index FET, for any aortic arch pathology.Secondary intervention after FET is an important parameter to establish the success or failure of the index procedure. However, unplanned extensions are often reported with insufficient detail and follow up, and studies rarely differentiate between unplanned or adjunctive procedures. In addition, prediction of the need for extension is complicated by the response of the pathology to the index procedure.FET is a versatile, established surgical technique that allows for several applications in different pathologies and innovative adaptations. How, when, and why FET is extended needs to be reported in greater detail, with specific consideration given to the interaction of FET and endovascular devices in sizing, integrity, and possible complications.

Background PM01183 is a new compound that blocks active transcription, produces DNA breaks and apoptosis, and affects the inflammatory microenvironment. PM01183 showed strong antitumor activity in preclinical models of cisplatin-resistant epithelial ovarian cancer. Patients and methods Patients with platinum-resistant/refractory ovarian cancer were included in a two-stage, controlled, randomized (in a second stage), multicenter, phase II study. Primary endpoint was overall response rate (ORR) by RECIST and/or GCIG criteria. The exploratory first stage (n = 22) confirmed the activity of PM01183 as a single agent at 7.0 mg flat dose every 3 weeks (q3wk). The second stage (n = 59) was randomized and controlled with topotecan on days 1–5 q3wk or weekly (every 4 weeks, q4wk). Results ORR was 23% (95% CI, 13%–37%) for 52 PM01183-treated patients. Median duration of response was 4.6 months (95% CI, 2.5–6.9 months), and 23% (95% CI, 0%–51%) of responses lasted 6 months or more. Ten of the 12 confirmed responses were reported for 33 patients with platinum-resistant disease [ORR = 30% (95% CI, 16%–49%)]; for the 29 patients treated with topotecan in the second stage, no responses were found. Median PFS for all PM01183-treated patients was 4.0 months (95% CI, 2.7–5.6 months), and 5.0 months (95% CI, 2.7–6.9 months) for patients with platinum-resistant disease. Grade 3/4 neutropenia in 85% of patients; febrile neutropenia in 21% and fatigue (grade 3 in 35%) were the principal safety findings for PM01183. Conclusion PM01183 is an active drug in platinum-resistant/refractory ovarian cancer and warrants further development. The highest activity was observed in platinum-resistant disease. Its safety profile indicates the dose should be adjusted to body surface area (mg/m2). Trial code EudraCT 2011-002172-16.

To determine the recommended dose and antitumor activity of single-agent elisidepsin as a 24-h intravenous (i.v.) infusion fortnightly [biweekly, d1 and 15 every 4 weeks (q4wk); Arm A, dose-intensity strategy] or as a 3-h i.v. infusion weekly (d1, 8, 15 and 22 q4wk; Arm B, dose-density strategy) in adult patients with unresectable, locally advanced or metastatic pretreated esophageal, gastroesophageal junction and gastric cancer. Patients were randomized to one of two elisidepsin dosing schedules. Phase Ib starting doses were 8.0 mg flat dose (FD) in Arm A and 3.0 mg FD in Arm B. Phase II subsequently explored antitumor activity of both dosing schedules at the respective recommended doses. Forty-four patients received elisidepsin: 12 in stage Ib and 32 in stage II. The recommended doses were defined as 10 mg FD (Arm A) and 3.75 mg FD (Arm B). Both schedules were well tolerated. Most adverse events were mild or moderate, reversible and predictable with no meaningful differences between schedules. The pharmacokinetic profiles of both schedules were similar to those reported previously in patients with solid tumors treated with a comparable dose. An interim analysis found tumor control in one patient receiving elisidepsin fortnightly, and in none given elisidepsin weekly; patient accrual was therefore discontinued due to lack of efficacy. Both schedules at the recommended doses presented an acceptable safety profile, but lack of response means that we do not recommend further evaluation of single-agent elisidepsin as chemotherapy for unresectable, locally advanced or metastatic gastroesophageal cancer.

Purpose: To evaluate the safety and performance of the Treovance stent-graft. Methods: The global, multicenter RATIONALE registry ( ClinicalTrials.gov; identifier NCT03449875) prospectively enrolled 202 patients (mean age 73.0±7.8 years; 187 men) with abdominal aortic aneurysms (AAA) suitable for endovascular aneurysm repair (EVAR) using the Treovance. The composite primary safety endpoint was site-reported all-cause mortality and major morbidity. The primary efficacy outcome was clinical success. Further outcomes evaluated included technical success; stent-graft migration, patency, and integrity; endoleak; and aneurysm size changes. Results: Technical success was 96% (194/202); 8 patients had unresolved type I endoleaks at the end of the procedure. There was no 30-day mortality and 1% major morbidity (1 myocardial infarction and 1 bowel ischemia). Clinical success at 1 year was confirmed in 194 (96%) patients; 6 of 8 patients had new/persistent endoleaks and 2 had aneurysm expansion without identified endoleak. A total of 8 (4%) reinterventions were required during the mean 13.7±3.1 months of follow-up (median 12.8). At 1 year, the Kaplan-Meier estimate for freedom from reintervention was 95.6% (95% CI 91.4% to 97.8%). Other estimates were 95.5% (95% CI 91.7% to 97.6%) for freedom from endoleak type I/III and 97.4% (95% CI 94.2% to 98.9%) for freedom from aneurysm expansion. Thirteen (6.4%) patients died; no death was aneurysm related. Conclusion: The RATIONALE registry showed favorable safety and clinical performance of the Treovance stent-graft for the treatment of infrarenal AAAs in a real-world setting.

Background To determine the recommended dose (RD) of a combination of PM01183 and gemcitabine in patients with advanced solid tumors. Methods Forty-five patients received escalating doses of PM01183/gemcitabine on Days 1 and 8 every 3 weeks (d1,8 q3wk) following a standard 3 + 3 design. Results PM01183 3.5 mg flat dose (FD)/gemcitabine 1000 mg/m2 was the highest dose level tested. Dose-limiting toxicities (DLTs) were mostly hematological and resulted in the expansion of a lower dose level (PM01183 3.5 mg FD/gemcitabine 800 mg/m2); 19 patients at this dose level were evaluable but >30% had DLT and >20% had febrile neutropenia. No DLT was observed in 11 patients treated at PM01183 3.0 mg FD/gemcitabine 800 mg/m2, which was defined as the RD. This regimen was feasible and tolerable with manageable toxicity; mainly grade 3/4 myelosuppression. Non-hematological toxicity comprised fatigue, nausea, vomiting, and transaminases increases. Fifteen (33%) patients received ≥6 cycles with no cumulative hematological toxicity. Pharmacokinetic analysis showed no evidence of drug-drug interaction. Nine of 38 patients had response as per RECIST (complete [3%] and partial [21%]), for an overall response rate (ORR) of 24% (95% Confidence Interval [CI] 12-40%). Eleven patients (29%) had disease stabilization ≥4 months. Responses were durable (median of 8.5 months): overall median progression-free survival (PFS) was 4.2 months (95% CI, 2.7-6.5 months). Conclusions The RD for this combination is PM01183 3.0 mg FD (or 1.6 mg/m2)/gemcitabine 800 mg/m2 d1,8 q3wk. This schedule is well tolerated and has antitumor activity in several advanced solid tumor types.

Exposures of mechanical street sweeper operators to lead, asbestos, and dust were determined, and an evaluation of the factors contributing to the level of exposure was conducted. Factors evaluated included rain, frequency of sweeping, traffic volume, and age of the dwellings in the sweeping areas. Sampling was conducted during the months of July through September. Sweeping routes were categorized according to building age and were sampled under rain and no rain conditions. Sweeping frequency and traffic volumes were addressed retrospectively. Twenty-nine samples were collected. Total dust concentrations ranged from 0.26 to 3.55 mg/m3 (mean, 2.09 mg/m3). Lead concentrations ranged from 0.99 to 6.64 μg/m3 (mean, 3.16 μg/m3) and were higher than ambient levels measured by the local air pollution control agency (0.41–0.80 μg/m3). The range of lead concentrations in the street sweepings was 324–3228 μg/g (mean, 1700 μg/g). Lead concentrations in the airborne dust ranged from 400 to 5000 μg/g with a m...
