Incidence and Resolution of Eribulin-Induced Peripheral Neuropathy (IRENE) in Locally Advanced or Metastatic Breast Cancer: Prospective Cohort Study.

BACKGROUND: Eribulin, a halichondrin-class microtubule dynamics inhibitor, is a preferred treatment option for patients with advanced breast cancer who have been pretreated with an anthracycline and a taxane. Peripheral neuropathy (PN) is a common side effect of chemotherapies for breast cancer and other tumors. The Incidence and Resolution of Eribulin-Induced Peripheral Neuropathy (IRENE) noninterventional postauthorization safety study assessed the incidence and severity of PN in patients with breast cancer treated with eribulin. PATIENTS AND METHODS: IRENE is an ongoing observational, single-arm, prospective, multicenter, cohort study. Adult patients (≥18 years of age) with locally advanced or metastatic breast cancer and disease progression after 1-2 prior chemotherapeutic regimen(s) for advanced disease were treated with eribulin. Patients with eribulin-induced PN (new-onset PN or worsening of preexisting PN) were monitored until death or resolution of PN. Primary endpoints included the incidence, severity, and time to resolution of eribulin-induced PN. Secondary endpoints included time to disease progression and safety. RESULTS: In this interim analysis (data cutoff date: July 1, 2019), 67 (32.4%) patients experienced any grade eribulin-induced PN, and 12 (5.8%) patients experienced grade ≥3 eribulin-induced PN. Median time to resolution of eribulin-induced PN was not reached. Median time to disease progression was 4.6 months (95% CI, 4.0-6.5). Treatment-emergent adverse events (TEAEs) occurred in 195 (93.8%) patients and serious TEAEs occurred in 107 (51.4%) patients. CONCLUSION: The rates of any grade and grade ≥3 eribulin-induced PN observed in this real-world study were consistent with those observed in phase III randomized clinical trials. No new safety findings were observed.

[Delayed-Interval Delivery of an Extremely Preterm Twin after Abort of the First Twin and Emergency Total Cervical Occlusion at 19+1 Weeks of Gestation - a Case Report]. / Verlauf eines frühgeborenen Geminus nach totalem Muttermundsverschluss bei Spontanabort des ersten Geminus in der 19+1 Schwangerschaftswoche ­ Fallbericht und Literaturübersicht.

We report on the obstetric and neonatal course of a 34-year-old woman pregnant with twins, who presented at our clinic at 16+1 weeks of gestation with preterm premature rupture of membranes. We started intravenous antibiotic therapy with inpatient monitoring owing to the vitality and regular development of both twins, with anhydramnios in the leading twin. After a missed abortion of the leading twin at 19+1 weeks of gestation we decided on surgical intervention with assisted delivery of the aborted twin, leaving the placenta in situ with subsequent emergency total cervical occlusion. Afterwards, the single pregnancy could be continued until the 24th week of gestation. An urgent Caesarean section for early labor, premature rupture of membranes, and increasing signs of maternal infection was later performed. Overall, the postnatal course of the extremely preterm neonate was a success considering the gestational age. We conclude that the option of surgical interventions should be taken into account in similar cases in the future.

Echocardiography signs of early cardiac impairment in patients with breast cancer and trastuzumab therapy.

OBJECTIVE: Recent studies in breast cancer patients and Trastuzumab therapy (Herceptin) showed a development of a toxic cardiomyopathy as a severe complication. The aim of this study was to discover early changes in cardiac function and morphology. METHODS: We studied 42 female patients with Her-2/-neu over-expression in breast cancer by echocardiography before, 3, and 6 months after start of the adjuvant Herceptin therapy. All values were mean value ± standard deviation. RESULTS: After 3 or 6 months of a trastuzumab therapy we discovered significant increases in the diastolic and systolic left ventricle volume indices (LV-DVI 32.4 ± 8.5 vs. 38.5 ± 8.7 vs. 40.3 ± 10.3 ml/m², p < 0.001 and LV-SVI 12.6 ± 4.0 vs. 15.7 ± 4.7 vs. 17.2 ± 6.8 ml/m², p < 0.001), an increase of the end-diastolic and end-systolic LV diameter (LVEDD 46.8 ± 4.2 vs. 48.0 ± 4.7 vs. 49.7 ± 4.5 ml/m², p < 0.01; LVESD 28.3 ± 4.2 vs. 31.0 ± 4.7 vs. 32.3 ± 4.9 mm, p < 0.001), a reduced systolic ventricle function determined by the tissue Doppler imaging (TDI) velocity (9.2 ± 2.5 vs. 8.0 ± 1,7 vs. 7.7 ± 1.5 cm/s, p < 0.001), fractional shortening (39,6 ± 7.5 vs. 35.4 ± 7.4 vs. 35.2 ± 7.0%, p < 0.01), and the LV-EF Simpson biplane [62.0 ± 5.1 vs. 60.1 ± 6.3 (p = ns) vs. 58.4 ± 7.9%, p < 0.01] compared to pretreatment values. There was also an increase of the left atrial volume index (21.4 ± 6.2 vs. 26.2 ± 7.9 vs. 29.7 ± 8.8 ml/m², p < 0.001), a decrease of the median TDI atrial velocities (11.9 ± 2.4 vs. 10.5 ± 2.8 vs. 10.1 ± 2.1 cm/s, p < 0.01), an increase of the peak early diastolic filling velocities (73.1 ± 15.4 vs. 83.1 ± 16.4 vs. 82.2 ± 19.4 cm/s, p < 0.05), and an increase of the median mitral valve insufficiency degree (0.64 ± 0.65 vs. 1.03 ± 0.76 vs. 1.11 ± 0.73°, p < 0.001). We could not detect a significant increase in diastolic dysfunction. Also right heart diameters and function did not change significantly. Most patients stayed in an asymptomatic stage of cardiac disease. CONCLUSION: The blockade of Her2/-neu receptors with trastuzumab in patients with breast cancer led to measurable alterations of left ventricular volume, left atrial volume, and systolic function as early as 3 months after start of treatment.
