RESUMO
BACKGROUND: Mirvetuximab soravtansine (MIRV) is an antibody-drug conjugate comprising a folate receptor alpha (FRα)-binding antibody, cleavable linker, and the maytansinoid DM4, a potent tubulin-targeting agent. The randomized, open-label, phase III study FORWARD I compared MIRV and investigator's choice chemotherapy in patients with platinum-resistant epithelial ovarian cancer (EOC). PATIENTS AND METHODS: Eligible patients with 1-3 prior lines of therapy and whose tumors were positive for FRα expression were randomly assigned, in a 2 : 1 ratio, to receive MIRV (6 mg/kg, adjusted ideal body weight) or chemotherapy (paclitaxel, pegylated liposomal doxorubicin, or topotecan). The primary endpoint was progression-free survival [PFS, Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, blinded independent central review] in the intention-to-treat (ITT) population and in the prespecified FRα high population. RESULTS: A total of 366 patients were randomized; 243 received MIRV and 109 received chemotherapy. The primary endpoint, PFS, did not reach statistical significance in either the ITT [hazard ratio (HR), 0.98, P = 0.897] or the FRα high population (HR, 0.69, P = 0.049). Superior outcomes for MIRV over chemotherapy were observed in all secondary endpoints in the FRα high population including improved objective response rate (24% versus 10%), CA-125 responses (53% versus 25%), and patient-reported outcomes (27% versus 13%). Fewer treatment-related grade 3 or higher adverse events (25.1% versus 44.0%), and fewer events leading to dose reduction (19.8% versus 30.3%) and treatment discontinuation (4.5% versus 8.3%) were seen with MIRV compared with chemotherapy. CONCLUSIONS: In patients with platinum-resistant EOC, MIRV did not result in a significant improvement in PFS compared with chemotherapy. Secondary endpoints consistently favored MIRV, particularly in patients with high FRα expression. MIRV showed a differentiated and more manageable safety profile than chemotherapy.

Ovarian cancer (OC) is the most important cause of gynecological cancer-related mortality, with the majority of women presenting with advanced disease. Although surgery and chemotherapy can improve survival, the 5-year survival rates remain ominously low at 45%. Novel therapies are urgently needed. The presence of T cells in the OC tumor microenvironment is correlated with improved progression-free and overall survival, while the presence of regulatory T cells and expression of T-cell inhibitory molecules is correlated with a poor prognosis. These data indicate that immunotherapy could hold promise in improving the treatment of OC. In this review, we will discuss the rational of immunotherapy, highlight current results with cancer vaccines, adoptive T-cell therapy and immunomodulatory agents and summarize the immune effects of selected chemotherapeutic and radiotherapeutic agents.

Malignant struma ovarii is a rare clinical entity that poses a therapeutic challenge, as there is no 'gold standard' of care. We aimed to develop evaluation and treatment guidelines by reviewing presentation and outcomes of the available literature. We present a 60-year-old female with papillary thyroid carcinoma arising in a mature teratoma, and our multidisciplinary approach to care and follow-up. We examined 59 cases for characteristics, including rates of metastasis and recurrence, and response to surgical and adjuvant treatment. We found higher rates of metastasis and recurrence than traditionally reported, and found no recurrence in patients treated with oophorectomy, thyroidectomy, and I-131 radioablation. A multimodal approach to the treatment of malignant struma ovarii may improve survival and decrease risk of recurrence.

Most of the ovarian cancers originate from the ovarian surface epithelium derived from the coelomic mesothelium. The Met proto-oncogene encodes a transmembrane tyrosine kinase receptor (Met) that has the capacity to regulate cell proliferation and differentation and it is activated by hepatocyte growth factor. Trisomy of chromosome 7 and Met protein overexpression have been were observed in ovarian carcinomas, the papillary renal cancers and other solid tumors. Frequent mutations of Met proto-oncogene have been found in hereditary papillary renal cancer (HPRC) and most of the mutations are located in the tyrosine kinase domain. The aim of this study to perform a mutation analysis of exons 17 19 of Met proto-oncogene in epithelial ovarian tumors (EOTs). We have examined 24 tumor samples from patients, operated with EOTs. Mutation was detected in exon 18 in only one sample of 24 EOTs. Our results indicate that mutations located in the Met proto-oncogene is not a common event in EOT. It is not clear whether the mutation plays a role in the tumorigenesis or progression of EOT or not.

P53 and cyclin D1 are interacting regulatory genes and both are frequently altered in breast cancer. We analysed p53 mutation by SSCP and sequencing methods as well as p53 protein accumulation immunohistochemically in 34 consecutively operated breast tumors. None of 4 fibroadenomas revealed p53 mutation or p53 protein accumulation. Mutation of p53 was present in 7 carcinomas. Immunohistochemistry revealed accumulation of p53 protein in 6 carcinomas and there was a significant correlation between p53 mutation and protein accumulation. Overexpression of cyclin D1 protein was observed in 11 carcinomas by immunohistochemistry and no correlation was observed between cyclin D1 overexpression and p53 mutation or accumulation. Our data support the concept that the p53-cyclin D1 signal pathway and the cyclin D1 cascade are disregulated in breast cancer.

OBJECTIVE: To investigate the potential perinatal effects of Factor V Leiden mutation and 5,10 methylenetetrahydrofolate reductase C677T polymorphism in preeclamptic women. STUDY DESIGN: One hundred twenty preeclamptic women (N = 120) and 101 healthy pregnant controls (N = 101) were recruited and evaluated for frequency of Leiden and 5,10 methylenetetrahydrofolate reductase (MTHFR) mutations using polymerase chain reaction (PCR). Perinatal outcomes were then recorded and analyzed for all study participants and their neonates. RESULTS: Laboratory analysis yielded 22 (18.33%) heterozygous carriers of Factor V Leiden mutation among preeclamptic women and 3 (2.97%) heterozygous carriers among the healthy controls; differences between the two groups were found to be statistically significant [p < 0.001, the relative risk (RR) = 6.17, 95% confidence interval (95% CI) = 1.90-20.02]. Homozygous MTHFR mutations were found in 8 of 120 (6.67%) preeclamptic women and in 6 of the 101 (5.94%) healthy controls evaluated. Among preeclamptic women, episodes of hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome were reported in 7 of 22 (31.81%) of those with Factor V Leiden mutation and in 11 of 98 (11.22%) of those who were negative for the mutation. Group differences were determined to be statistically significant (p < 0.015, RR = 2.83, 95% CI = 1.24-6. 48). Perinatal indicators collected from the two groups included frequency of intrauterine growth retardation, birth weight, and gestational age. No statistically different perinatal outcomes were found between Factor V Leiden positive and negative preeclamptic women. In addition, MTHFR gene polymorphism did not appear to be correlated with the development of preeclampsia. CONCLUSION: Although the frequency of Factor V Leiden mutation appears to be significantly higher among preeclamptic women, the mechanism of pathogenesis and potential influence on perinatal outcomes is not yet well understood. Relatively high rates of HELLP syndrome among those with Factor V Leiden mutation suggest that this thrombogene mutation may play a significant role in hemostatic system activation. Our results suggest that the role of MTHFR polymorphism and other factors such as folic acid supplementation will require more extensive analysis in controlling worldwide morbidity and mortality associated with this important maternal condition.

BACKGROUND: Granulosa cell tumors constitute only 5% of ovarian neoplasms, and their coexistence with pregnancy is extremely rare. Juvenile granulosa cell tumor has a good prognosis if it is confined to the ovary, but this type behaves more aggressively than the adult type at advanced stages. CASES: We report on successful completion of two singleton pregnancies and deliveries of normal infants in two young women with juvenile granulosa cell tumor diagnosed and treated during pregnancy. This tumor has rarely been described in association with pregnancy. The presence of trisomy 12 as a single chromosomal abnormality was detected in these two tumors. Both tumors were localized strictly to the ovary, so conservative surgery was applied and proved sufficient to remove all tumor tissue. Follow-up showed no signs of recurrence 18 and 53 months after the interventions. CONCLUSION: These cases support the contention that trisomy 12 is a nonrandom chromosome abnormality in juvenile granulosa cell tumors and that pregnancy may affect nuclear stability in this tumor.

The shedding, tissue distribution and quasispecies composition of feline coronaviruses were studied in naturally and experimentally infected cats. The infection remained subclinical, but the majority of the animals shed the virus via faeces throughout the experiment. Sequences corresponding to the viral nucleocapsid region were amplified by reverse-transcription polymerase chain reaction from the cortex, dura mater, pancreas, lungs, third eyelid, and the heart muscle in four cases. Interestingly, the ORF7b viral region - a supposed virulence factor - was detected in fewer organs, raising the possibility that this region can be affected by deletions during virus replication in vivo. It is demonstrated that the composition of the viral quasispecies differs between organs, and that genomic regions with different functions undergo distinct processes of selection, which should be considered during the evolution of feline coronaviruses.

The prevalence and phylogeny of feline coronaviruses were studied in urban cat populations by sampling of 113 clinically healthy cats. Rectal swab samples were subjected to a nested reverse-transcription polymerase chain reaction, specific for the conservative nucleocapsid region of the virus genome. More than 30% of the sampled animals proved positive for the presence of feline coronaviruses. The nucleotide sequences of amplified 440 bp products were determined, aligned and the phylogenetic analysis revealed noticeable genetic clusters among the prevalent feline coronaviruses in the surveyed geographic area. These findings will hopefully contribute to the elucidation of the epidemiology of feline infectious peritonitis.

The DNA of thirty-three Hungarian bovine herpesvirus isolates originating from cattle with various clinical symptoms were compared by restriction endonuclease analysis using HindIII, EcoRI and BstEII enzymes. The EcoRI and HindIII cleavage patterns were similar to those of isolates studied in other countries. Based on the cleavage patterns, the Hungarian isolates could be assorted into groups and subgroups according to the classification system proposed by Metzler et al. (1985, 1986). Based on a new BstEII cleavage pattern observed in group 1, the establishment of two new subgroups, 1a and 1b, were proposed. Three isolates belonged to subgroup 1a, sixteen to 1b, seven to 2a, five to 2b, and one to group 3, which has recently been reclassified as BHV-5. Additionally, one of the isolates showed a mixed cleavage pattern of 1a and 1b. However, no strict correlation was found between the different clinical forms and the established DNA fingerprint groups. There was no evidence of a change in the prevalence of the different genotypes when comparing isolates collected at different times of a 24-year period.

Postweaning multisystemic wasting syndrome (PMWS), a new disease in Hungary, was recognized in a swine herd located in Southeast Hungary, during the early winter of 1999. The first clinical signs of paleness, anaemia, and leanness appeared immediately after weaning, at the age of 40-50 days. Pustules were frequently observed on the skin of the trunk, and signs of necrotic dermatitis were also visible. A syndrome of poor growth and wasting was characteristic of the affected pigs. A porcine circovirus (PCV), the suspected causative agent, was detected by polymerase chain reaction (PCR). Sequencing data and restriction endonuclease (RE) analysis of the PCR products suggested that the virus belonged to the PCV-II group where all the causative agents of PMWS are also grouped.

A high-performance liquid chromatography--diode array detection (HPLC-DAD) method was developed for determining the deoxynivalenol (DON) content of wheat and other cereals. The samples were extracted with a mixture of acetonitrile and water (84 + 16). Part of the extract was evaporated and purified on Florisil and activated charcoal columns. HPLC separation was performed on a C18 column, using acetonitrile-water (8 + 92) as eluent. Diode array detection (DAD) was performed at 218 and 236 nm, by determination of the UV spectrum. Quantitative analysis was carried out by the external standard method, using the UV spectrum obtained by DAD for confirmation. The recovery rate of DON was 75 +/- 3.1% and the detection limit was 0.05 mg/kg DON. Using this method, the DON content of 99 feeding wheat samples grown in the northeastern part of Hungary in 1998 was determined. Eighty-eight percent of the samples originating from three counties contained 0.94 mg/kg DON on the average. The highest individual value was 4.3 mg/kg. DON contamination of wheat was of higher prevalence (100%) and severity (0.27-4.3 mg/kg) in the southeastern county of Békés than in Szabolcs county located in the northeastern part of Hungary (ratio of positive samples: 82%; DON concentration: 0.05-1.3 mg/kg). The higher than usual DON contamination of feeding wheat can be explained by the rainy summer weather. DON contamination of feeding wheat poses a major risk to the production and animal health status of pig herds.

Bovine torovirus is an established aetiological agent of disease in cattle, while porcine torovirus has only been isolated from healthy animals. Evidence for the presence of torovirus has been described in several European countries and also in the United States. A survey was performed to detect toroviruses in Hungary by means of sampling ten swine and nine bovine herds. Rectal swabs and faecal specimens were collected from diarrhoeic calves and from weaned piglets. The samples were tested by the reverse transcription-polymerase chain reaction (RT-PCR) using torovirus-specific primers and the positive samples were further examined by electron microscopy (EM). Torovirus was detected in 4 diarrhoeic calves (out of 111) and in 10 healthy weaned pigs (out of 200 tested), representing two of the 9 calf herds and two of the 10 pig herds tested. This is the first report of exact diagnosis of torovirus in Hungary.

In order to obtain data on the occurrence of the protozoan parasite Neospora caninum as a potential factor in the aetiology of reproduction problems in cattle, 97 postabortion sera were examined by ISCOM ELISA and IFAT for the presence of antibodies in N. caninum. The results showed 10% and 9% seropositivity by the ELISA and IFAT, respectively. In 2 of the 10 seropositive cases no other fetopathogenic agents (such as Chlamydia sp., Leptospira spp. or bovine viral diarrhoea virus) were detected. These data confirm the presence of N. caninum in cattle in Hungary.

The quasispecies nature of three animal pathogenic RNA viruses of field origin was examined by testing variants of classical swine fever virus (CSFV) originating from geographically different areas, feline coronavirus (FCoV) detected from the same animal by successive sampling, and rabbit haemorrhagic disease virus (RHDV) originating from successive outbreaks in the same geographic area. Clinical samples were investigated using reverse transcriptase polymerase chain reaction (RT-PCR) and ensuing single strand conformational polymorphism (SSCP) assay. By the combination of these methods even subtle differences could be detected among the amplified fragments of the same virus species of different origin. FCoV proved to comprise the most and CSFV the less heterogeneous virus quasispecies. The results show that the combination of RT-PCR and SSCP provides novel and highly sensitive means for the characterisation of RNA viruses, with special regard to genome composition, evolution, features of pathogenicity and molecular epizootiology.

Between the 1st July 1990 and the 30th June 1995, 34 caesarean hysterectomies and 2708 (22%) caesarean sections were performed from 12,227 births on the I. Department of Obstetrics and Gynaecology Semmelweis University Medical School in Budapest. From all 34 cases, hysterectomy were performed in 9 cases (26%) after complicated delivery, in other 9 cases (26%) during elective caesarean section and in 16 cases (47%) during urgent caesarean section. The incidence of caesarean hysterectomy is 2.7/1000 labour in our study. We listed the placenta increta, placenta accreta, placenta adherens, placenta praevia, uteroplacental apoplexia, scar disruption, uterus rupture, atony, sepsis puerperalis, abruptio placentae, haematoma paravaginale as urgent indications and so elective indications were myoma uteri, cervical carcinoma, ovarial tumour and in-situ cervical carcinoma. We collect the elective and urgent indications of caesarean hysterectomy and summarize the possible operative and postoperative complications in our study.

beta-catenin is a continuously expressed cytoplasmic protein that has an important role is both E-cadherin-mediated cell-cell adhesion and in activation of Wnt/Wingless transcriptional pathway. The accumulation of stabilized beta-catenin caused by the mutation of the exon 3 of beta-catenin gene can stimulate the T-cell factor/Lymphoid enhancing factor-mediated transcriptional activation. The activation of transcriptional pathway may through oncogenes is an important step of the oncogenesis in solid tumors. In this study we analyzed mutations in exon 3 of the beta-catenin gene in 18 sporadic epithelial ovarian tumors. Three mutations were found from these 18 ovarian tumor samples which contained 8 serous, 3 mucinous, 5 endometrioid, one malignant Brenner-type tumor and one transitional cell carcinoma. Two mutations occurred in endometrioid-type (in 47 and 55 codons) and one in serous-type (in 47 codon) ovarian carcinomas, and both mutations were missense and somatic. The patients with mutated beta-catenin gene appeared from the younger patients under the age of 50. Our results suggest that the stabilization of beta-catenin protein by the mutation of CTNNB1 gene can contribute to the multistep process of the oncogenesis of epithelial ovarian tumors. Furthermore these mutations mostly occurs in the endometrioid-type of EOT, but can appear in other types such as serous-type ovarian tumor.

This study included all the patients with ovarial cysts > or = 6 cm that were persisted during pregnancy in the 1st. Department of Obstetrics and Gynecology of Semmelweis University Medical School between 1. January 1991. and 31. December 1996. There were 14,640 deliveries and 15 cases which presented by above mentioned criteria with 1/976 incidency and 3 cases from all were malignant tumor with 1/4880 incidency. All patients underwent surgical intervention. Surgical management were spreaded on one adnexa in 12 cases of all, on both adnexum in only 3 cases and hysterectomy with both side adnexectomies was performed in only one case. Based on complications in two cases emergency laparotomies and in 13 cases elective extirpation of ovarial cysts were performed. There was no loss of pregnancy in the postoperative period. Because of the high risk of complications and malignancy we supported that surgical intervention in the second trimester is a definitive therapy for ovarial cysts complicated pregnancy.
