Real world data of niraparib in platinum sensitive relapsed ovarian cancer: A multicenter experience of the MITO group.

OBJECTIVE: PARP (poly adenosine diphosphate [ADP]-ribose polymerase) inhibitors are approved as maintenance therapy in platinum sensitive ovarian cancer (OC), in first line and in the recurrent setting, regardless of BRCA mutational status. Real-world data after the introduction of these agents are needed to evaluate whether the benefit observed in phase III randomized clinical trials can be translated into clinical practice. The aim of our study was to provide real-life data on efficacy and safety of niraparib administered as maintenance in platinum sensitive relapsed OC patients (PSROC). METHODS: This retrospective/prospective observational study included relapsed OC patients that received niraparib as maintenance, at the time of platinum sensitive recurrence within the Italian expanded-access program. Clinical data at the time of diagnosis and at the time of recurrence were collected and analyzed. Median progression free survival (PFS) and overall survival (OS) were calculated as the time from start of niraparib treatment to subsequent radiologically confirmed relapse and death or last contact, respectively. RESULTS: Among 304 eligible patients, 260 (85%) had BRCA wild-type tumor and 36. (11.9%) were BRCA mutated. Median PFS was 9.1 months (95% CI: 6.9-11.2) and 10.3 months (95% CI: 7.0-13.5) in the BRCAwt and BRCAmut cohorts, respectively. Furthermore, median OS was 41.7 months (95% CI: 31.6-41.9) and 34.6 months (95% CI: N.E.) in the BRCAwt and BRCAmut cohorts, respectively. CONCLUSION: Data from this large real-life dataset suggested that maintenance with niraparib in the real-life setting of platinum sensitive OC recurrence is effective and well tolerated.

Carboplatin and paclitaxel plus avelumab compared with carboplatin and paclitaxel in advanced or recurrent endometrial cancer (MITO END-3): a multicentre, open-label, randomised, controlled, phase 2 trial.

BACKGROUND: Adding immunotherapy to first-line chemotherapy might improve outcomes for patients with advanced or recurrent endometrial cancer. We aimed to compare carboplatin and paclitaxel versus avelumab plus carboplatin and paclitaxel as first-line treatment with avelumab given concurrent to chemotherapy and as maintenance after the end of chemotherapy. METHODS: MITO END-3 is an open-label, randomised, controlled, phase 2 trial conducted at 31 cancer institutes, hospitals, and universities in Italy. Eligible patients were aged 18 years or older with histologically confirmed advanced (FIGO stage III-IV) or recurrent endometrial cancer, an Eastern Cooperative Oncology Group (ECOG) performance status of 0-1, and no previous systemic anticancer therapy as primary treatment for advanced or metastatic disease. Participants were randomly assigned (1:1) using a computerised minimisation procedure stratified by centre, histology, and stage at study entry, to either receive carboplatin (area under the curve [AUC] 5 mg/mL × min) and paclitaxel (175 mg/m2; standard group) intravenously every 3 weeks for six to eight cycles or avelumab (10 mg/kg intravenously) added to carboplatin and paclitaxel (experimental group) every 3 weeks and then every 2 weeks as a single maintenance treatment after the end of chemotherapy until disease progression or unacceptable toxicity. Patients, treating clinicians, and those assessing radiological examinations were not masked to study treatment. The primary endpoint was investigator-assessed progression-free survival, measured in the intention-to-treat (ITT) population. Patients who received at least one dose of study drug were included in the safety analysis. Experimental group superiority was tested with 80% power and one-tailed α 0·20. This trial is registered with ClinicalTrials.gov (NCT03503786) and EudraCT (2016-004403-31). FINDINGS: From April 9, 2018, to May 13, 2021, 166 women were assessed for eligibility and 39 were excluded. 125 eligible patients were randomly assigned to receive carboplatin and paclitaxel (n=62) or avelumab plus carboplatin and paclitaxel (n=63) and included in the ITT population. The median follow-up was 23·3 months (IQR 13·2-29·6) and was similar between the two groups. 91 progression-free survival events were reported, with 49 events in 62 patients in the standard group and 42 events in 63 patients in the experimental group. The median progression-free survival was 9·9 months (95% CI 6·7-12·1) in the standard group and 9·6 months (7·2-17·7) in the experimental group (HR of progression or death 0·78 [60% CI 0·65-0·93]; one-tailed p=0·085). Serious adverse events were reported more frequently in the experimental group (24 vs seven events in the standard group); neutrophil count decrease was the most frequent grade 3-4 adverse event (19 [31%] of 61 patients in the experimental group vs 26 [43%] of 61 patients in the standard group). Two deaths occurred in the experimental group during treatment (one respiratory failure following severe myositis [possibly related to treatment] and one cardiac arrest [not related to treatment]). INTERPRETATION: Adding avelumab to first-line chemotherapy deserves further testing in patients with advanced or recurrent endometrial cancer, although consideration of mismatch repair status is warranted. FUNDING: Pfizer.

Children under 6 years with acute headache in Pediatric Emergency Departments. A 2-year retrospective exploratory multicenter Italian study.

BACKGROUND: Preschool age (i.e. children under six years of age) represents a red flag for requiring neuroimaging to exclude secondary potentially urgent intracranial conditions (PUIC) in patients with acute headache. We investigated the clinical characteristics of preschoolers with headache to identify the features associated with a greater risk of secondary "dangerous" headache. METHODS: We performed a multicenter exploratory retrospective study in Italy from January 2017 to December 2018. Preschoolers with new-onset non-traumatic headache admitted to emergency department were included and were subsequently divided into two groups: hospitalized and discharged. Among hospitalized patients, we investigated the characteristics linked to potentially urgent intracranial conditions. RESULTS: We included 1455 preschoolers with acute headache. Vomiting, ocular motility disorders, ataxia, presence of neurological symptoms and signs, torticollis and nocturnal awakening were significantly associated to hospitalization. Among the 95 hospitalized patients, 34 (2.3%) had potentially urgent intracranial conditions and more frequently they had neurological symptoms and signs, papilledema, ataxia, cranial nerves paralysis, nocturnal awakening and vomiting. Nevertheless, on multivariable logistic regression analysis, we found that only ataxia and vomiting were associated with potentially urgent intracranial conditions. CONCLUSION: Our study identified clinical features that should be carefully evaluated in the emergency department in order to obtain a prompt diagnosis and treatment of potentially urgent intracranial conditions. The prevalence of potentially urgent intracranial conditions was low in the emergency department, which may suggest that age under six should not be considered an important risk factor for malignant causes as previously thought.

Benign Acute Childhood Myositis: Our Experience on Clinical Evaluation.

BACKGROUND: Benign acute childhood myositis (BACM) is a transient condition mainly affecting children of school age characterized by muscle pain, typically localized to the calf muscle with symmetrical lower extremity pain and difficulty in walking. Usually, the symptomatology is preceded by a viral infection including influenza, parainfluenza, rotavirus, and mycoplasma. METHODS: The case series was conducted in four pediatric hospitals in Catania, Italy, over a 12-year observational period. Clinical examination, laboratory data, course, treatment, and complications of the affected children were extracted from electronic medical records of each hospital. RESULTS: For the case series, 50 children diagnosed with BACM were enrolled: the mean age of affected children was 5.35 years, 86% of were males, and in 56% the affections occurred during the winter. In the affected children, the clinical picture was characterized by previous fever and/or symptoms of inflammation of the upper airways, and followed by pain in the lower extremities up to uncoordinated gait. In 17 cases the etiological agent was isolated, including the influenza virus type B as the most frequent and influenza virus type A, Mycoplasma pneumoniae, beta-hemolytic streptococcus, and herpes simplex virus. Children were treated with supportive therapy. In all the children the muscular symptomatology had a good evolution with progressive marked reduction of pain and of the high level of CKemia. Neither clinical recurrences nor sequelae were reported. CONCLUSION: BACM shows to have in most of the cases a favorable evolution, a spontaneous remission of symptoms, and a good prognosis. However, the disorder generates parental distress for the acute presentation and the striking muscle dysfunction. It is worthy a rapid and early diagnosis to avoid unnecessary diagnostic investigations and a careful follow-up necessary to exclude persistence of symptoms or creatine kinase elevation.

Autoimmune encephalitis and CSF anti-AMPA GluR3 antibodies in childhood: a case report and literature review.

Acute autoimmune encephalitis is a severe neurological disorder presenting with altered level of consciousness, confusion, irritability, headache, vomiting, and in some cases seizures. An infective event precedes by 1-2 weeks the onset of the symptoms. Cognitive impairment is considered the cardinal symptom. The autoimmune encephalitis comprises an increasingly group of inflammatory brain disorder caused by an underlying abnormal immune response to the CNS to the infective agent. In children, several antibodies have been recorded as causative agent. Among these, GAD65, MOG, and NMDAR antibodies are more commonly reported and with less frequency, the Dopamine-2 receptor, GABA A receptor, GABA B receptor, and Glycinereceptorandm-GluR5. We report here a 10-year-old male with acute autoimmune encephalitis with altered status of consciousness and severe cerebral involvement at the brain-MRI. Serum and cerebrospinal fluid disclosed the presence of anti-AMPA-GluR3 antibodies suggesting a possible pathogenetic correlation with the disorder presented by the proband. Precocious treatment with intravenous methylprednisolone and immunoglobulin resulted in progressive but constant improvement. At 3-month follow-up, the clinical condition of the child and the neuro-radiological brain anomalies returned to the normal. At the 2-year follow-up, no recurrence or other disturbances were reported.

Characteristics and outcome of BRCA mutated epithelial ovarian cancer patients in Italy: A retrospective multicenter study (MITO 21).

OBJECTIVE: Around 15% of epithelial ovarian cancer (EOC) patients (pts) harbor a germline BRCA1 or 2 mutation, showing different features than BRCA wild-type pts. The clinical and pathological features of an Italian BRCA mutated EOC cohort were described. METHODS: We retrospectively analyzed clinical, pathological and mutational data from a cohort of Italian BRCA mutated EOC pts. treated in 15 MITO centers between 1995 and 2017. RESULTS: Three-hundred thirty-one pts. were recorded. Two-hundred forty (72%) and 91 (27.5%) pts. harbored a BRCA1 and BRCA2 mutation, respectively. Median age at diagnosis was 52 years. The most frequent diagnosis was a high grade serous FIGO III or IV EOC and platinum doublet in first-line was administered to almost all pts. Fifty-three % of them had no residual disease (R = 0) at surgery. Median progression-free-survival (mPFS) after first-line chemotherapy was 29 months. Expected percentage of pts. alive at 5 years was 72.5% (CI 60.2-80.8%) and R = 0 predicted a significantly longer overall survival (OS). Sixty-six pts. (19,9%) had both an EOC and a breast cancer (BC) diagnosis. The first diagnosis was BC in 81,8% of cases with a mean interval between the two diagnoses (IBTDs) of 132.4 months. Mutational data show that the founder mutation c.5266dupC in BRCA1 was the most frequently recorded. CONCLUSIONS: This is the largest Italian BRCA mutEOC cohort. The only predictor of longer OS was R = 0. EOC pts. that developed subsequently a BC are long-term survivors.

Vitamin B12 Deficiency and West Syndrome: An Uncommon but Preventable Cause of Neurological Disorder. Report on Three Cases, One of Them with Late Onset during Vitamin B12 Treatment.

Vitamin B12 is a water-soluble vitamin that plays a fundamental role as an essential cofactor for two enzymes responsible for the production of succinyl-CoA and methionine. Vitamin B12 deficiency can occur in infants and may be related to the breastfeeding mother's adherence to a vegan diet or somatic diseases in the mother. It should be differentiated from inborn errors of vitamin B12 metabolism. Herein, we report the cases of three infants with West syndrome; all three were breastfed by mothers who followed a strict vegan diet. In one of the three infants, West syndrome developed during treatment with vitamin B12 and normalization of the vitamin B12 level. Early treatment and replacement therapy are worthwhile to prevent serious neurological problems and to improve the patient's clinical course.

Second-line Eribulin in Triple Negative Metastatic Breast Cancer patients. Multicentre Retrospective Study: The TETRIS Trial.

Introduction: Large and consistent evidence supports the use of eribulin mesylate in clinical practice in third or later line treatment of metastatic triple negative breast cancer (mTNBC). Conversely, there is paucity of data on eribulin efficacy in second line treatment. Methods: We investigated outcomes of 44 mTNBC patients treated from 2013 through 2019 with second line eribulin mesylate in a multicentre retrospective study involving 14 Italian oncologic centres. Results: Median age was 51 years, with 11.4% of these patients being metastatic at diagnosis. Median overall survival (OS) and progression free survival (PFS) from eribulin starting were 11.9 (95%CI: 8.4-15.5) and 3.5 months (95%CI: 1.7-5.3), respectively. We observed 8 (18.2%) partial responses and 10 (22.7%) patients had stable disease as best response. A longer PFS on previous first line treatment predicted a better OS (HR=0.87, 95%CI: 0.77-0.99, p= 0.038) and a longer PFS on eribulin treatment (HR=0.92, 95%CI: 0.85-0.98, p=0.018). Progression free survival to eribulin was also favorably influenced by prior adjuvant chemotherapy (HR=0.44, 95%CI: 0.22-0.88, p=0.02). Eribulin was generally well tolerated, with grade 3-4 adverse events being recorded in 15.9% of patients. Conclusions: The outcomes described for our cohort are consistent with those reported in the pivotal Study301 and subsequent observational studies. Further data from adequately-sized, ad hoc trials on eribulin use in second line for mTNBC are warranted to confirm our findings.

On clinical findings of Bickerstaff's brainstem encephalitis in childhood.

A short review on the clinical presentation of pediatrics cases of Bickerstaff brain encephalitis emphasizing the broad clinical spectrum of the disease. Cases of pediatric Bickerstaff's brainstem encephalitis collected on three electronic medical databases (PubMed, Cochrane Library and Scopus Web of Science) are reviewed. The inclusion criteria of the cases were based on the clinical characteristics of the disorder in the pediatric age. We reviewed 20 articles on Bickerstaff's brainstem encephalitis, identifying 40 pediatric cases focused on the clinical symptoms. We saw that the prevalence was higher in male subjects, and the median age at diagnosis was 8 years. The phenotype of pediatrics patients was similar to previously published literature. We identify three cases of overlapping forms between Bickerstaff brain encephalitis and Guillain-Barré Syndrome in patients with lower limbs weakness and typical signs of Bickerstaff brain encephalitis, suggesting a combined involvement of the central and peripheral nervous system. Although there is no defined data on incidence and prevalence in the literature, Bickerstaff's brainstem encephalitis appears to be a rare disorder, especially in children. The incidence of Bickerstaff brain encephalitis and Guillain-Barré Syndrome, and Miller Fisher Syndrome has been underrated in the past, primarily due to an underestimation of the forms with a Peripheral Nervous System involvement. Bickerstaff brain encephalitis usually has a rapid and acute onset within 2-4 weeks, characterized by a typical picture of ophthalmoplegia, hyperreflexia, cerebellar symptoms as ataxia. The subsequent manifestations of hyperreflexia or consciousness disturbances as drowsiness, sleepiness, or coma, indicative of central involvement, suggest a Bickerstaff brain encephalitis clinical diagnosis.

Poland Syndrome with Atypical Malformations Associated to a de novo 1.5 Mb Xp22.31 Duplication.

Poland's syndrome (PS; OMIM 173800) is a rare congenital syndrome which consists of absence or hypoplasia of the pectoralis muscle. Other features can be variably associated, including rib defects. On the affected side other features (such as of breast and nipple anomalies, lack of subcutaneous tissue and skin annexes, hand anomalies, visceral, and vertebral malformation) have been variably documented. To date, association of PS with central nervous system malformation has been rarely reported remaining poorly understood and characterized. We report a left-sided PS patient carrying a de novo 1.5 Mb Xp22.31 duplication diagnosed in addiction to strabismus, optic nerves and chiasm hypoplasia, corpus callosum abnormalities, ectopic neurohypophysis, pyelic ectasia, and neurodevelopmental delay. Since, to our knowledge, this features' association has not been previously reported, we argue that this case may contribute to further widening of the variability of PS phenotype.

Palbociclib plus endocrine therapy in HER2 negative, hormonal receptor-positive, advanced breast cancer: A real-world experience.

Data from 423 human epidermal growth factor receptor 2-negative (HER2-), hormone receptor-positive (HR+) advanced breast cancer (aBC) patients treated with palbociclib and endocrine therapy (ET) were provided by 35 Italian cancer centers and analyzed for treatment outcomes. Overall, 158 patients were treated in first line and 265 in second/later lines. We observed 19 complete responses and 112 partial responses. The overall response rate (ORR) was 31% (95% confidence interval [CI], 26.6-35.4) and clinical benefit was 52.7% (95% CI, 48-57.5). ORR was negatively affected by prior exposure to everolimus/exemestane ( p = 0.002) and favorably influenced by early line-treatment ( p < 0.0001). At 6 months, median progression-free survival was 12 months (95% CI, 8-16) and median overall survival was 24 months (95% CI, 17-30). More favorable outcomes were associated with palbociclib in early lines, no visceral metastases and no prior everolimus/exemestane. The main toxicity reported was neutropenia. Our results provide further support to the use of palbociclib with ET in HER2-, HR+ aBC. Differences in outcomes across patients subsets remain largely unexplained.

Optic Neuropathy, Secondary to Ethmoiditis, and Onodi Cell Inflammation during Childhood: A Case Report and Review of the Literature.

Optic neuropathy consists of several etiological events. The primary etiologies of its acute form include optic neuritis, ischemic optic neuropathy, inflammatory (nondemyelinating) disorders, and trauma. Its subacute and chronic forms are most often linked to compressive, toxic, nutritional, or hereditary-genetic causes. Visual loss, dyschromatopsia, and visual field defects are the presenting symptoms. The Onodi cell (sphenoethmoidal air cell) is an anatomic variant located laterally and superior to the sphenoid sinus; it is closely related to the optic nerve. Onodi cell disorders are rare and may be unnoticed in differential diagnoses of patients with ocular and neurological manifestations. Here, we present the case of a 12-year-old boy with headache and acute loss of sight characterized by hemianopsia in the left eye and retrobulbar optic neuropathy caused by left sphenoethmoidal sinusitis with the presence of Onodi cell inflammation. The diagnosis was confirmed by multilayered paranasal computed tomography and cerebral magnetic resonance imaging. Therapeutic treatment resulted in gradual improvement: at the 2-week follow-up, the patient no longer had headaches and his visual acuity returned to normal. Inflammation of Onodi cells should be considered in children with headache and abnormal vision.

Arterial ischemic stroke (AIS) in childhood: clinical report from a single control center.

INTRODUCTION: Stroke is the clinical designation for a rapidly developing loss of brain function due to an interruption in the blood supply to all or part of the brain. It is the third cause of death in adults and one of the top 10 causes in pediatric age. The perinatal period of onset is the second only to adult age group in the incidence of stroke. Arterial ischemic stroke during childhood occurs most frequently in the perinatal period with an incidence of 1 out 2300-5000 live infant births. MATERIALS AND METHODS: This is a retrospective study that includes 28 patients affected by perinatal arterial ischemic stroke. Family and gestational history, risk factors of perinatal stroke, gender and clinical data of affected children and outcome are reported. RESULTS: A stroke family history was registered in three unrelated families. Gestational history disclosed cases of threats of abortion, preterm delivery, hyperthermia, gestosis, and placental disorders. In the children, onset of seizures were reported within 3 days of life and diagnosis of stroke was confirmed by brain MRI which disclosed involvement of the middle cerebral artery in all the cases. Hemilateral cerebral palsy, epileptic seizures, and intellectual disability from mild to severe were the most frequent complications. CONCLUSION: Stroke is still a common and dreadful events in perinatal period as this disorder is often unpredictable and cause of severe neurological impairment.

Hypoglossal nerve paralysis in a child after a dental procedure.

Unilateral palsy of the hypoglossal nerve is a rare complication of orthodontic procedures. The main reported causes of HNP are: orthopedic and otorhinolaryngology surgical interventions, and in particular maneuvers involving compression or overstretching of the hypoglossal nerve, dental procedures and traumas, and also infections, motoneuron disorders, tumors, vascular diseases. Diagnosis is usually performed by electrophysiology studies (EMG-VCN), and brain magnetic resonance imaging (MRI) is useful to exclude other causes. The prognosis depends on the location and extension of the damage. Currently there is not a standardized treatment approach except the speech therapy, although, in some cases, the high-dose steroid treatment could be useful. We describe the case of a ten-year-old female, who was admitted in our Unit after a deviation of the tongue associated with dysarthria and dysphagia, occurred after the application of a mobile orthodontic device.

Rhabdomyomas and tuberous sclerosis complex: our experience in 33 cases.

BACKGROUND: Rhabdomyomas are the most common type of cardiac tumors in children. Anatomically, they can be considered as hamartomas. They are usually randomly diagnosed antenatally or postnatally sometimes presenting in the neonatal period with haemodynamic compromise or severe arrhythmias although most neonatal cases remain asymptomatic. Typically rhabdomyomas are multiple lesions and usually regress spontaneously but are often associated with tuberous sclerosis complex (TSC), an autosomal dominant multisystem disorder caused by mutations in either of the two genes, TSC1 or TSC2. Diagnosis of tuberous sclerosis is usually made on clinical grounds and eventually confirmed by a genetic test by searching for TSC genes mutations. METHODS: We report our experience on 33 cases affected with rhabdomyomas and diagnosed from January 1989 to December 2012, focusing on the cardiac outcome and on association with the signs of tuberous sclerosis complex. We performed echocardiography using initially a Philips Sonos 2500 with a 7,5/5 probe and in the last 4 years a Philips IE33 with a S12-4 probe. We investigated the family history, brain, skin, kidney and retinal lesions, development of seizures, and neuropsychiatric disorders. RESULTS: At diagnosis we detected 205 masses, mostly localized in interventricular septum, right ventricle and left ventricle. Only in 4 babies (12%) the presence of a mass caused a significant obstruction. A baby, with an enormous septal rhabdomyoma associated to multiple rhabdomyomas in both right and left ventricular walls died just after birth due to severe heart failure. During follow-up we observed a reduction of rhabdomyomas in terms of both number and size in all 32 surviving patients except in one child. Eight patients (24,2%) had an arrhythmia and in 2 of these cases rhabdomyomas led to Wolf-Parkinson-White Syndrome. For all patients the arrhythmia spontaneously totally disappeared or was reduced gradually. With regarding to association with tuberous sclerosis, we diagnosed tuberous sclerosis clinically in 31 babies (93,9%). CONCLUSION: Rhabdobyomas are tumors with favorable prognosis because they frequently do not cause symptoms and they often regress in numbers and size. Nevertheless, due to frequent association with tuberous sclerosis complex and the resulting neurological impairment, the prognosis can result unfavorable.

The first absolute gravity and height reference network in Sicily.

The purpose of this work is to provide the methodological and instrumental framework for the establishment of a new absolute gravity and height reference network in Sicily. The aim of the network is to contribute to the new reference systems in the Italian area, useful for the scientific and technological activities related to the gravity field and to the proper definition of a modern height system in this region. The network is composed of 5 stations, evenly distributed to form a large mesh, which roughly covers the entire Sicily. Since four of the five selected stations were measured also in the 1990s, it was also possible to evaluate whether long-term gravity changes occurred at these sites (basic requirement for a reference network) and check the long-term ground deformation patterns, using data from the closest GPS/GNSS stations. The observed gravity changes over a time interval of about 30 years at the absolute stations and in the surrounding areas, confirm the long-term stability of the selected areas/sites.

Single-Agent Trabectedin Versus Physician's Choice Chemotherapy in Patients With Recurrent Ovarian Cancer With BRCA-Mutated and/or BRCAness Phenotype: A Randomized Phase III Trial.

PURPOSE: Literature evidence suggests that trabectedin monotherapy is effective in patients with recurrent ovarian cancer (OC) presenting BRCA mutation and/or BRCAness phenotype. METHODS: A prospective, open-label, randomized phase III MITO-23 trial evaluated the activity and safety of trabectedin 1.3 mg/m2 given once every 3 weeks (arm A) in BRCA 1/2 mutation carriers or patients with BRCAness phenotype (ie, patients who responded to ≥two previous platinum-based treatments) with recurrent OC, primary peritoneal carcinoma, or fallopian tube cancer in comparison with physician's choice chemotherapy in the control arm (arm B; pegylated liposomal doxorubicin, topotecan, gemcitabine, once-weekly paclitaxel, or carboplatin). The primary end point was overall survival (OS) evaluated in the intention-to-treat population. RESULTS: Overall, 244 patients from 21 MITO centers were randomly assigned (arm A = 122/arm B = 122). More than 70% of patients received ≥three previous chemotherapy lines and 35.7% had received a poly (ADP-ribose) polymerase inhibitor (PARPi) before enrollment. Median OS was not significantly different between the arms: arm A: 15.8 versus arm B: 17.9 months (P = .304). Median progression-free survival was 4.9 months in arm A versus 4.4 months in arm B (P = .897). Among 208 patients evaluable for efficacy, the objective response rate was 17.1% in arm A and 21.4% in arm B, with comparable median duration of response (5.62 v 5.66 months, respectively). No superior effect was observed for trabectedin in the prespecified subgroup analyses according to BRCA mutational status, chemotherapy type, and pretreatment with a PARPi and/or platinum-free interval. Trabectedin showed a higher frequency of grade ≥3 adverse events (AEs), serious AEs, and serious adverse drug reactions compared with control chemotherapy. CONCLUSION: Trabectedin did not improve median OS and showed a worse safety profile in comparison with physician's choice control chemotherapy.

The chromatin remodelling component SMARCB1/INI1 influences the metastatic behavior of colorectal cancer through a gene signature mapping to chromosome 22.

BACKGROUND: INI1 (Integrase interactor 1), also known as SMARCB1, is the most studied subunit of chromatin remodelling complexes. Its role in colorectal tumorigenesis is not known. METHODS: We examined SMARCB1/INI1 protein expression in 134 cases of colorectal cancer (CRC) and 60 matched normal mucosa by using tissue microarrays and western blot and categorized the results according to mismatch repair status (MMR), CpG island methylator phenotype, biomarkers of tumor differentiation CDX2, CK20, vimentin and p53. We validated results in two independent data sets and in cultured CRC cell lines. RESULTS: Herein, we show that negative SMARCB1/INI1 expression (11% of CRCs) associates with loss of CDX2, poor differentiation, liver metastasis and shorter patients' survival regardless of the MMR status or tumor stage. Unexpectedly, even CRCs displaying diffuse nuclear INI1 staining (33%) show an adverse prognosis and vimentin over-expression, in comparison with the low expressing group (56%). The negative association of SMARCB1/INI1-lack of expression with a metastatic behavior is enhanced by the TP53 status. By interrogating global gene expression from two independent cohorts of 226 and 146 patients, we confirm the prognostic results and identify a gene signature characterized by SMARCB1/INI1 deregulation. Notably, the top genes of the signature (BCR, COMT, MIF) map on the long arm of chromosome 22 and are closely associated with SMARCB1/INI1. CONCLUSION: Our findings suggest that SMARCB1/INI1-dysregulation and genetic hot-spots on the long arm of chromosome 22 might play an important role in the CRC metastatic behavior and be clinically relevant as novel biomarkers.

Hemiconvulsion-hemiplegia-epilepsy syndrome. Magnetic resonance findings in a 3-year-old boy.

The term 'hemiconvulsion-hemiplegia-epilepsy syndrome' (HHE) was first used by Gastaut et al. to describe the se-quential combination of unilateral or predominantly unilateral clonic seizures (hemiconvulsion), occurring during the first 2 years of life, immediately followed by an ipsilateral flaccid hemiplegia lasting 7 or more days. In the following phase partial epileptic seizures occur. We report a case of HHE syndrome in a 3-year-old boy with partial seizures (hemiconvulsion lasting 15-30 minutes) followed by left hemiplegia and hyporeflexia. Magnetic resonance imaging showed diffuse and high signal hyperintensity of the whole right cerebral hemisphere. Diffusion-weighted images showed a reduction of the apparent diffusion coefficient in the subcortical region. Magnetic resonance arterio-graphy showed a narrow flow signal in the distal territory of the right middle cerebral artery. The authors emphasize the importance of neuroradiological findings in early diagnosis and in the follow-up of HHE syndrome.
