RESUMEN
BACKGROUND: Poly(ADP-ribose) polymerase (PARP) inhibitor maintenance therapy is the standard of care for some patients with advanced ovarian cancer. We evaluated the efficacy and safety of PARP inhibitor rechallenge. PATIENTS AND METHODS: This randomized, double-blind, multicenter trial (NCT03106987) enrolled patients with platinum-sensitive relapsed ovarian cancer who had received one prior PARP inhibitor therapy for ≥18 and ≥12 months in the BRCA-mutated and non-BRCA-mutated cohorts, respectively, following first-line chemotherapy or for ≥12 and ≥6 months, respectively, following a second or subsequent line of chemotherapy. Patients were in response following their last platinum-based chemotherapy regimen and were randomized 2 : 1 to maintenance olaparib tablets 300 mg twice daily or placebo. Investigator-assessed progression-free survival (PFS) was the primary endpoint. RESULTS: Seventy four patients in the BRCA-mutated cohort were randomized to olaparib and 38 to placebo, and 72 patients in the non-BRCA-mutated cohort were randomized to olaparib and 36 to placebo; >85% of patients in both cohorts had received ≥3 prior lines of chemotherapy. In the BRCA-mutated cohort, the median PFS was 4.3 months with olaparib versus 2.8 months with placebo [hazard ratio (HR) 0.57; 95% confidence interval (CI) 0.37-0.87; P = 0.022]; 1-year PFS rates were 19% versus 0% (Kaplan-Meier estimates). In the non-BRCA-mutated cohort, median PFS was 5.3 months for olaparib versus 2.8 months for placebo (HR 0.43; 95% CI 0.26-0.71; P = 0.0023); 1-year PFS rates were 14% versus 0% (Kaplan-Meier estimates). No new safety signals were identified with olaparib rechallenge. CONCLUSIONS: In ovarian cancer patients previously treated with one prior PARP inhibitor and at least two lines of platinum-based chemotherapy, maintenance olaparib rechallenge provided a statistically significant, albeit modest, PFS improvement over placebo in both the BRCA-mutated and non-BRCA-mutated cohorts, with a proportion of patients in the maintenance olaparib rechallenge arm of both cohorts remaining progression free at 1 year.

BACKGROUND: In the SOLO2 trial (ENGOT Ov-21; NCT01874353), maintenance olaparib in patients with platinum-sensitive relapsed ovarian cancer (PSROC) and BRCA mutation significantly improved progression-free survival (PFS) and prolonged overall survival (OS). Following disease progression on olaparib, efficacy of subsequent chemotherapy remains unknown. PATIENTS AND METHODS: We conducted a post-hoc hypothesis-generating analysis of SOLO2 data to determine the efficacy of different chemotherapy regimens following RECIST disease progression in patients who received olaparib or placebo. We evaluated time to second progression (TTSP) calculated from the date of RECIST progression to the next progression/death. RESULTS: The study population comprised 147 patients who received chemotherapy as their first subsequent treatment after RECIST progression. Of these, 69 (47%) and 78 (53%) were originally randomized to placebo and olaparib arms, respectively. In the placebo-treated cohort, 27/69 and 42/69 received non-platinum and platinum-based chemotherapy, respectively, compared with 24/78 and 54/78, respectively, in the olaparib-treated cohort. Among patients treated with chemotherapy (N = 147), TTSP was significantly longer in the placebo than in the olaparib arm: 12.1 versus 6.9 months [hazard ratio (HR) 2.17, 95% confidence interval (CI) 1.47-3.19]. Similar result was obtained on multivariable analysis adjusting for prognostic factors at RECIST progression (HR 2.13, 95% CI 1.41-3.22). Among patients treated with platinum-based chemotherapy (n = 96), TTSP was significantly longer in the placebo arm: 14.3 versus 7.0 months (HR 2.89, 95% CI 1.73-4.82). Conversely, among patients treated with non-platinum-based chemotherapy (n = 51), the TTSP was comparable in the placebo and olaparib arms: 8.3 versus 6.0 months (HR 1.58, 95% CI 0.86-2.90). CONCLUSIONS: Following progression from maintenance olaparib in the recurrent setting, the efficacy of platinum-based subsequent chemotherapy seems to be reduced in BRCA1/2-mutated patients with PSROC compared to patients not previously receiving poly (ADP-ribose) polymerase inhibitors (PARPi). The optimal strategy for patients who relapse after PARPi is an area of ongoing research.

OBJECTIVES: Ovulation-related inflammation is suspected to have a causal role in ovarian carcinogenesis, but there are no human models to study the molecular pathways. Our aim is to develop such an ex-vivo model based on human fallopian tube (FT) epithelium exposed to human follicular fluid (FF). METHODS: FT epithelium was dissociated from normal surgical specimens. FF was obtained from donors undergoing in-vitro fertilization. The cells were cultured on collagen-coated Transwells and incubated with FF for various periods of time. The transcriptomic changes resulting from FF treatment were profiled using Affymetrix expression arrays. Specific characteristics of the FT pre-cancerous lesions were studied using immunohistochemistry, immunofluorescence, RT-PCR and XTT assay. RESULTS: We show that FF exposure causes up-regulation of inflammatory and DNA repair pathways. Double stranded DNA breaks are induced. There is a minor increase in cell proliferation. TP53, which is the hallmark of the precursor lesion in-vivo, is accumulated. Levels of expression and secretion of Interleukin-8 are significantly increased. CONCLUSIONS: Our model addresses the main non-genetic risk factor for ovarian cancer, namely the impact of ovulation. This study demonstrates the biological implications of in-vitro exposure of human FT epithelial cells to FF. The model replicates elements characterizing the precursor lesions of ovarian cancer, and warrants further investigation of the linkage between repeated exposure to ovulation-related damage and accumulation of neoplastic changes.

Background: Pelvic exenteration (PE) is a major surgical procedure used as a salvage therapy for patients with locally advanced or recurrent pelvic malignancies. Urinary reconstruction is a major part of PE and is often associated with high rates of post-operative complications. In the current study we evaluate the short and long-term urological outcomes following PE for Colo-Rectal (CR) and gyneco-oncological (GO) malignancies. Methods: Study included 22 patients who underwent PE for recurrent or locally advanced CR and GO malignancies in our institution between the years 2010-2018. The endpoint was post-operative freedom from urological complications. Results: Of 22 patients included, 13 (59 %) and 9 (41 %) underwent PE for CR and GO malignancies respectively. The mean age of the patients was 54 years. The median follow-up was 19 months. Seven (78 %) patients with GO malignancy and 11 (85 %) with CR malignancy underwent PE for local recurrence. Hydronephrosis prior to surgery existed in 8 (36.3 %) patients, of which, 5 patients required kidney drainage via nephrostomy tube. Two patients underwent posterior pelvic exenteration (PPE) with bladder preservation whereas the remaining 20 underwent cystectomy with urinary diversion by ileal conduit. Hydronephrosis post PE developed in 13 patients (59 %). eight (36 %) patients needed kidney drainage by nephrostomy tubes post PE, of these, 6 (75 %) had disease recurrence. The 2 years freedom from kidney drainage was 68 %, however the median time for kidney drainage was 0.5 months. The median overall survival was 12.5 months. Conclusion: The rate of urological complications following PE is relatively high and associated with disease recurrence.
RESUMEN
Human immunodeficiency virus (HIV) infection is a risk factor for thrombotic microangiopathy (TMA). We sought whether a severe deficiency in ADAMTS13, the enzyme specifically involved in the cleavage of von Willebrand factor, was associated with specific presenting features and outcome in HIV-associated TMA. In this prospective, multicentre, case-control study, 29 patients of 236 in the French Network on TMA had an HIV-associated TMA. Seventeen patients with severe ADAMTS13 deficiency (ADAMTS13 <5% HIV(+) group) were compared to 12 patients with a detectable ADAMTS13 activity (ADAMTS13 >or=5% HIV(+) group). HIV(+) patients were also compared to 62 patients with idiopathic TMA, either with (45 patients, ADAMTS13 <5% idiopathic group) or without (17 patients, ADAMTS13 >or=5% idiopathic group) severe ADAMTS13 deficiency. ADAMTS13 <5% HIV(+) patients had less AIDS-related complications than ADAMTS13 >or=5% HIV(+) patients (23.5% versus 91.6%, respectively, P = 0.0005) and their median CD4(+) T cell count was higher (P = 0.05). TMA-associated death rate was higher in ADAMTS13 >or=5% HIV(+) patients than in ADAMTS13 <5% HIV(+) patients (50% versus 11.7%, respectively, P = 0.04). In ADAMTS13 <5% patients, TMA-associated death rate was comparable between HIV(+) and idiopathic patients (15.5% in idiopathic patients, P-value was non-significant). By contrast, TMA-associated death rate in ADAMTS13 >or=5% HIV(+) patients was higher than in idiopathic patients (11.7% in idiopathic patients, P = 0.04). In conclusion, HIV-associated TMA with severe ADAMTS13 deficiency have less AIDS-related complications and a higher CD4(+) T cell count. TMA prognosis is better and comparable to this of idiopathic forms.

INTRODUCTION: Focused ultrasound under real-time MR guidance and control (MRgFUS) can be used for the thermal ablation of tissue. Currently this technique is used clinically for the noninvasive treatment of uterine leiomyomas and is in clinical evaluation for breast cancer, adenomyosis and other indications. MRgFUS is being tested for pain relief in patients suffering from bone metastases. This is the first case to report on MRgFUS for pain relief in patients suffering from recurrent cervical carcinoma. CASE REPORT: A 29-year-old patient with recurrent squamous cell carcinoma of cervix following radical hysterectomy, chemotherapy and radiation was treated by MRgFUS due to pelvic mass unresponsive to conventional treatment that caused intractable pain. Following two treatments the patient experienced a marked reduction in pain and increase in Karnovsky Performance Status (KPS) from 50% to 80%. DISCUSSION: Palliative treatment of pain with noninvasive MRgFUS in cases of recurrent cervical carcinoma may be a safe and efficient alternative to other invasive techniques.

The use of plasma exchange (PE) in the autoimmune diseases is encouraged in France. Since 1990, the national registry of PE allows an analysis of the evolution of the coverage of these pathologies. The variation of the number of patients treated by PE is correlated in respect to the results of the therapeutic studies. After a decrease of PE activity in these indications during the 90s, one observes a new increase of the patients treated because of the validation of new indications. Autoimmune diseases represent the third cause of morbidity in developed countries, with a global prevalence of 5%, and concerns four groups of pathologies of organs or systems (neurology, haematology, nephrology and vasculitis). In 1976, Lockwood demonstrated the place of plasma exchanges (PE) in Goodpasture's syndrome [Lockwood CM, Rees AJ, Pearson TA, Evans DJ, Peters DK, Wilson CB. Immunosuppression and plasma exchange in the treatment of Goopasture's syndrome. Lancet 1976;1(7962):723-6. [1]], with a significant decrease of antibodies during large volume exchanges. In the 80s, several prospective studies began to estimate the efficiency of PE in other autoimmune diseases. The national registry of the Société Française d' Hémaphérèse, has collected the epidemiological and technical data of PE since 1985. This work analyses the evolution of the validated indications, between 1990 and 2005 in France.

Growth factors of the epidermal growth factor (EGF)/neuregulin family are involved in tumor progression and, accordingly, antibodies that intercept a cognate receptor, epidermal growth factor receptor (EGFR)/ERBB1, or a co-receptor, HER2, have been approved for cancer therapy. Although they might improve safety and delay onset of chemoresistance, no anti-ligand antibodies have been clinically approved. To identify suitable ligands, we surveyed fluids from ovarian and lung cancer patients and found that amphiregulin (AREG) is the most abundant and generalized ligand secreted by advanced tumors. AREG is a low affinity EGFR ligand, which is upregulated following treatment with chemotherapeutic drugs. Because AREG depletion retarded growth of xenografted ovarian tumors in mice, we generated a neutralizing monoclonal anti-AREG antibody. The antibody inhibited growth of ovarian cancer xenografts and strongly enhanced chemotherapy efficacy. Taken together, these results raise the possibility that AREG and other low- or high-affinity binders of EGFR might serve as potential targets for cancer therapy.

In 2002 WAA decided to start a world-wide apheresis registry to gain insight into the extent of treatment, adverse events, and to facilitate contacts among centers when treatment indications are rare and experience limited. Stem cell and other blood products collections intended for therapeutic application can also be entered. The WAA planned to use the French Registry. Its translation into English has not been accomplished and the fiscal obligations for that registry has not, as yet, been determined or considered and approved by the WAA Board. From Dec 2002 the proposed registry (a merged version of the French, Canadian and Swedish registries) can be immediately implemented. We now cordially invite all centers to join that registry. Please, also inform colleagues at other centers in your country to join. E-mail and address lists of colleagues in your country who have not registered will be welcomed. The site is at: Go to World Apheresis Registry; Login code to test the Registry is: al61tms. Then apply for a specific login code for your center. We welcome you to this registry for your input of data. You will not be charged any registration fee. The registry includes a randomization system that can be used for local or multi center studies (randomization by in-center basis allows you to make your own studies). It includes a formula that increases the chance to get a more even distribution between groups also for smaller sample sizes.

OBJECTIVE: Comparison of side effects (fever shivering and/or allergic reactions, collapse, symptomatic hypocalcaemia) of the different substitution fluids used during therapeutical plasmapheresis. DESIGN: Multicentric retrospective comparative study designed to explore the side effects due to the replacements fluids (albumin alone or associated with dextran 40, modified fluid gelatin, hydroxyethyl starch), and to determine the best combination in patients undergoing plasmapheresis. PATIENTS: 46,895 procedures were performed on 5,167 patients between 1990 and 1994. The analysis concerns 33,962 sessions, divided into two groups (group 1: 21,079 sessions from 1990 to 1992 comparing albumin alone versus combined albumin-macromolecules and the different combinations among these, group 2: 12,883 sessions in 1993-1994 comparing albumin alone versus albumin-hydroxyethyl starch). Because of the diversity of the products used, 13,029 sessions were not studied because groups of small sample sizes were formed. MEASUREMENTS AND RESULTS: In group 1, the comparison of albumin + macromolecules with albumin alone, shows the best haemodynamic tolerance, lower frequency of fever shivering and/or allergic reactions in the albumin alone subgroup. On the other hand, hypocalcaemia is significantly higher in this subgroup. The combinations albumin + dextran 40 (but after hapten inhibition) and albumin + hydroxyethyl starch are equivalent. Albumin + modified fluid gelatin is the combination presenting the highest incidence in terms of allergic manifestations. In group 2, albumin + hydroxyethyl starch versus albumin alone, the former is preferable in terms of the three side effects studied. CONCLUSION: The results of this study show a combination of albumin 4% hydroxyethyl starch to replace plasma during plasma exchange to be the method presenting the lowest morbidity and the best cost/effectiveness ratio.

Modalities of oxygen therapy for pregnant women intoxicated with carbon monoxide (CO) are ill defined. Hyperbaric oxygen (HBO) is presumed to be hazardous to the pregnancy. On the other hand CO entails anoxic injuries in the mother and fetus. We have entered 44 pregnant women who sustained an acute carbon monoxide poisoning at home, into a prospective study in order to assess HBO tolerance. They were treated within 5.3 +/- 3.7 h (range: 1-12) of the intoxication with a combination of 2 h of HBO at a pressure of 2 atmospheres absolute (ATA) and 4 h of normobaric oxygen, irrespective of the clinical severity of the intoxication and of the age of pregnancy. Six patients were lost to obstetric follow-up. Only 2 patients sustained a spontaneous abortion: 1 within 12 h and 1 within 15 days of the intoxication. Thirty-four women gave birth to normal newborns. Finally 1 elected to undergo abortion for reasons unrelated to the intoxication and 1 gave birth to a baby with Down's syndrome. There is no evidence that HBO was involved with either abortion of our study. We conclude that HBO may be carried out in pregnant women acutely intoxicated with carbon monoxide.

The French Registry for plasma exchange (PE) was set up in 1985. For 14 years it has allowed analysis of the techniques used along with the indications and complications. Recent analysis shows a slight fall in activity as some studies have ended, while the neurological disorders remain the most frequent indications for PE. The important changes observed over the years are the increased use of the centrifugation technique, the development of plasma and whole blood treatment and plasma substitution using a mixture of albumin and pentastarch. The French Registry for PE is the largest such database which, along with the Canadian Registry for therapeutic hemapheresis, allows both retrospective and prospective studies.

The French plasma exchange registry created in 1985 lists the indications, techniques and complications of the French therapeutic haemapheresis. In 2001 it contains the data of more than 16,700 patients for a total of 153,641 sessions. The indications concern five groups of pathologies (neurology, haematology, nephrology, vasculitis, and endocrinology). Until 2000, the neurology represented the most important group but the use of the high dose IgIV for Guillain-Barre and myasthenia gravis decreased the indications. The haematology became most important group treated because of the increase of the TTP and HUS number treated. The endocrinology (familial hypercholesterolemia) represents at present 10% of the patients treated for 18.7% of the sessions. The vascular access little changed since 1985, the peripheral venous access being the most used. The plasma substitution initially based on the albumin alone was gradually replaced by an association albumin macromolecules, in particular hydroxyethylstarch since 1990. After the observation of the side effects due to starches we observed an increase of the albumin alone use. The immediate complications decreased in half in 15 years. The French plasma exchange registry is the largest world database of haemapheresis with the cooperation of about 80 centres, allowing numerous scientific studies.

All cases of combined vaginal-abdominal deliveries at the Department of Obstetrics and Gynecology, Chaim Sheba Medical Center, over an eight-year period (1984-1991) were reviewed. During this period a total of 38,821 deliveries took place. Of 722 (1.9%) twin deliveries, 354 (48.8%) were by cesarean section; 19 were combined deliveries, including 5% of all twins delivered by cesarean section and 2.6% of all twins delivered. High transverse lie and prolapse of the umbilical cord were the main indications for delivery by cesarean section of the second twin. In order to diminish the number of combined deliveries and to increase obstetric skills and experience, a program or protocol for vaginal twin deliveries is indicated.

This is a retrospective study of the computed tomography (CT) examinations and medical records of 243 consecutive pediatric patients sent for CT studies after blunt abdominal trauma. The purpose of the study was to determine the frequency and significance of periportal tracking identified by CT, and correlate this finding with liver enzyme levels and liver injury. Periportal tracking (PPT) was divided into four grades (0-3) depending upon the distribution of decreased attenuation adjacent to the portal vessels. Circumferential PPT extending to the periphery of the liver (grade 3) was found in 20/243 children. They had a higher incidence of liver parenchymal injury seen on CT 20% versus 0.5% in combined PPT grades 0-2. Sixteen children with grade 3 PPT and no liver injury had significantly elevated liver enzymes as compared to children with combined 0-2 grade PPT. Eleven of the 20 children with grade 3 PPT had no other CT evidence of intraabdominal injury and none of these patients developed intraabdominal hemorrhage. Thus, grade 3 periportal tracking as an isolated abnormality did not indicate a clinically significant liver injury in any patient.

Digoxin-specific antibodies (Fab) are currently the treatment of choice for digoxin intoxication. These fragments bind to digoxin, leading to Fab-digoxin complexes, and promote the release of receptor-bound digoxin. These complexes are renally excreted. In the case of anuria, they could be dissociated and lead to renewed intoxication. In this case plasma exchanges are proposed. We report the case of an anuric patient with digoxin intoxication, treated with a Fab injection, followed by a plasma exchange 16 hours later, a second Fab injection was given followed by two plasma exchanges, 38 and 86 hours later. The disappearance of cardiac abnormalities showed the efficiency of the Fab, the drop in serum digoxin concentration and the high digoxin concentration in the exchanged plasma indicate effective elimination. The association of Fab and plasma exchanges could be proposed in the case of digoxin intoxication in the anuric patient.

Campylobacter fetus is a rare cause of endocarditis and endoaortitis: the authors believe this to be the second reported case of infection of an intracardiac prosthesis. The patient was a man who had already undergone replacement of the aortic valve and ascending aorta, and a gastrectomy, which were predisposing factors. The portal of entry was not found. The diagnosis was confirmed by positive blood cultures and transoesophageal echocardiography. The outcome was rapidly fatal despite antibiotic therapy and surgery, because of the seriousness of the lesions (pseudo-aneurysm of the aorta ruptured into the right atrium), the precarity of the terrain and surgical difficulties.

The purpose of this study was to estimate the incidence, mortality, and causes of carbon monoxide intoxications in France. A survey was conducted in the department of the Hauts-de-Seine, which is representative of the French population. Data were collected through a headquarters that had direct contact with all department emergency organizations and to a technical laboratory. During the 3-y study, 735 cases that were related to 291 events were reported. Thirty-six patients died. The average incidence of carbon monoxide intoxications was 17.5 per 100,000 inhabitants. Poisoning was caused by fires in 36 events and by car exhausts in 12. For the remaining events, causes were determined as follows for 196: water heaters (57%), boiler (20.5%), coal stove (9%), brazier (4%), cooker (2%), heating device (1.5%), and miscellaneous (6%). The main mechanisms of intoxication were a defective device, poor ventilation, or poor evacuation of combustion gases. Carbon monoxide intoxication occurs frequently in France, and preventive actions are warranted.

Methotrexate toxicity is rare but extremely severe. When complete, it consists of ulcerations of the gastrointestinal mucosae responsible for necrotizing enteritis, erythroderma, bone marrow aplasia, interstitial pneumonia, hepatitis and organic renal failure with diuresis. Toxicity is facilitated by pre-existing renal impairment, third sector and abstention or underdosage of foliculinic acid prescribed as antagonist. The diagnosis rests on serum assays, the results of which must be interpreted taking into account the assay method and the time elapsed between the injection of methotrexate and its assay in serum. The multivisceral pathology observed may totally regress, as in the case reported here. Treatment is based on symptomatic measures, starting with maintenance of an abundant and alkaline diuresis, and on the parenteral administration of folinic acid in doses that vary with the authors.

AIM: To define factors that could help select, in a cohort of gynecologic cancer patients with malignant gastro-intestinal obstruction, those most likely to benefit from palliative surgery. METHODS: In this retrospective study of patients with malignant gastro-intestinal obstruction who underwent palliative surgery in our institute over 7 years, outcome measures were oral intake, chemotherapy, and 30-day, 60-day and overall survival. Based on Cox proportional-hazards regression models and Kaplan-Meier curves with log-rank tests, a prognostic score was developed to identify those most likely to benefit from surgery. RESULTS: Sixty-eight palliative surgeries were performed in 62 patients with ovarian (69.1%), primary-peritoneal (8.8%), cervical (11.8%) or uterine (10.3%) malignancies. Procedures were colostomy (26.5%), ileostomy (39.7%), colonic stent (1.5%), gastrostomy (7.3%), gastroenterostomy (5.9%) and bypass/resection and anastomosis (19.1%). Eighteen patients died prior to discharge, within 3-81 days (median 25 days). The 30-day and 60-day mortality rates were 14.7% and 29.4%, respectively. Postoperative oral-intake and chemotherapy rates were 65% and 53%, respectively, with albumin level identified on multivariate analysis as the only significant predictor of both. Median postoperative survival was 106 days (3-1342). Bypass/resection and anastomosis was associated with improved survival. Ascites below 2 L, younger age, ovarian primary tumor, and higher blood albumin correlated with longer postoperative survival. A prognostic index based on these factors was found to identify patients with increased 30-day and 60-day mortality. CONCLUSIONS: Our proposed prognostic index, based on age, primary tumor, albumin and ascites, might help select those gynecological cancer patients most likely to benefit from palliative surgery.
