Decisional needs of patients with recurrent high-grade glioma and their families.

Background: High-grade gliomas are aggressive and life-threatening brain tumors. At the time of recurrence, the patients and their families need to decide on future treatment. None of the treatment options are curative, and tradeoffs between benefits and harms must be made. This study aimed to explore the patients' and family members' decisional needs when making the decision. Methods: We performed semi-structured individual interviews with patients and family members to explore their experiences during the decision making. A phenomenological hermeneutical analysis was conducted. Results: A total of 15 patients and 14 family members aged 22-79 years participated in the study. Most of the family members were partners to the patient. The findings were centered around three interrelated and concurrently occurring themes: (I) A patient- and family-centered decision making, including the subtheme of being a supportive family member; (II) Balanced information and a trustful professional encounter; and (III) The value of hope. We found that both the patients and family members preferred to be involved in the decision making and that a trustful relationship with the surgeon, balanced and tailored information, and sufficient time to make the decision were essential. The experience of hope had a significant influence on patients' decisions. Conclusion: This study found that patient and family involvement, balanced information, and hope were the primary decisional needs of patients and family members at the time of recurrent high-grade glioma. Patients and family members can have different decisional needs, making individual needs assessment essential to decisional support.

Patients' experiences of the decision-making process for clinical trial participation.

Clinical decision-making about participating in a clinical trial is a complex process influenced by overwhelming information about prognosis, disease, and treatment options. The study aimed to explore patients' experiences of the decision-making process when patients are presented with the opportunity to participate in a cancer clinical trial and to shed light on how patients experience the health communication, the nurse's role, and the physician's role. A qualitative study design was applied. Nine patients with advanced cancer were interviewed after being informed about their treatment options. Data were analyzed using thematic analysis. The results showed that patients made treatment decisions mainly guided by their emotions and trust in the physician. Furthermore, the physicians had a great impact on the decisions, and the nurse's role was associated with conversations about how to manage life. The study highlights the importance of talking about prognosis and addressing the patient's existential issues, particularly in this context of advanced cancer. The study elucidates a need for healthcare professionals to engage in health communication about life when it is coming to an end.

Practitioners' views on shared decision-making implementation: A qualitative study.

INTRODUCTION: Shared decision-making (SDM) refers to the collaboration between patients and their healthcare providers to make clinical decisions based on evidence and patient preferences, often supported by patient decision aids (PDAs). This study explored practitioner experiences of SDM in a context where SDM has been successfully implemented. Specifically, we focused on practitioners' perceptions of SDM as a paradigm, factors influencing implementation success, and outcomes. METHODS: We used a qualitative approach to examine the experiences and perceptions of 10 Danish practitioners at a cancer hospital experienced in SDM implementation. A semi-structured interview format was used and interviews were audio-recorded and transcribed. Data was analyzed through thematic analysis. RESULTS: Prior to SDM implementation, participants had a range of attitudes from skeptical to receptive. Those with more direct long-term contact with patients (such as nurses) were more positive about the need for SDM. We identified four main factors that influenced SDM implementation success: raising awareness of SDM behaviors among clinicians through concrete measurements, supporting the formation of new habits through reinforcement mechanisms, increasing the flexibility of PDA delivery, and strong leadership. According to our participants, these factors were instrumental in overcoming initial skepticism and solidifying new SDM behaviors. Improvements to the clinical process were reported. Sustaining and transferring the knowledge gained to other contexts will require adapting measurement tools. CONCLUSIONS: Applying SDM in clinical practice represents a major shift in mindset for clinicians. Designing SDM initiatives with an understanding of the underlying behavioral mechanisms may increase the probability of successful and sustained implementation.

Analysis of HOXA9 methylated ctDNA in ovarian cancer using sense-antisense measurement.

DNA promoter methylation is an early event in tumorigenesis and holds promise as a valuable marker in ovarian cancer (OC). It can be measured using circulating tumor specific DNA (ctDNA) isolated from the bloodstream. Sensitivity, however, is a limiting factor of its diagnostic feasibility in OC. DNA methylation analyses are based on bisulfite conversion, resulting in two DNA strands that are no longer complementary. The current standard strategy would then target only one of the double stranded DNA strands, but the potential to increase the sensitivity by targeting both DNA strands is available. In this study, we aimed at evaluating the diagnostic potential of methylated HOXA9 ctDNA in OC by targeting both the DNA sense and antisense strand. Methylated HOXA9 was detected in the plasma of 47/79 (59.5%) patients with newly diagnosed OC using sense-antisense droplet digital PCR. Simultaneous sense-antisense measurement increased the sensitivity by 14.6% (51.9% to 59.5%) as compared to antisense only. In patients with FIGO stage I-II disease the sensitivity was increased by 25%. In conclusion, simultaneous measurement targeting both DNA strands can increase the sensitivity and the analytical approach appears valuable in the diagnostic setting of OC.

The PROMova study comparing active and passive use of patient-reported outcome measures in ovarian cancer follow-up: effect on patient-perceived involvement, satisfaction with care, and usefulness.

BACKGROUND: Patients with ovarian cancer often experience substantial health problems and side effects resulting in reduced quality of life (QoL). Different models of using patient-reported outcome measures (PROMs) during follow-up may improve the quality of care. This national, multicenter observational study investigated the effect of active use of PROMs on patient-perceived involvement, satisfaction with care, unmet needs, and QoL during follow-up of ovarian cancer. MATERIAL AND METHODS: Ovarian cancer patients were recruited at the end of primary treatment at eight centers in Denmark. During 18 months of follow-up patients repeatedly completed European Organization for Research and Treatment of Cancer (EORTC) questionnaires covering health related QoL and symptoms. At the sites using PROMs actively (ACT), the clinician had access to an overview of the patient's scores during the clinical encounter. Clinicians using PROMs passively were alerted in case of severe development of symptoms. Following each encounter, patients evaluated their health service experience by completing the CollaboRATE scale of involvement in decision making, the Patient Experience Questionnaire, and ad hoc questions covering patient-perceived usefulness of the PROMs. RESULTS: A total of 223 patients were enrolled, i.e., 168 (75.3%) at five sites using ACT and 53 (23.8%) at three sites using them passively. We found no statistically significant difference in involvement in the decision making, satisfaction with care, unmet needs, and QoL between the two groups. The majority of patients found it useful to complete the PROMs, although it did not seem to significantly support them in raising issues with the oncologist. CONCLUSION: Active use of PROMs did not improve patients' experience of involvement in follow-up care as compared to passive use.

Shared decision making in high-grade glioma patients-a systematic review.

BACKGROUND: Shared decision making (SDM) has proven to be a valuable approach in different patient populations when treatment decisions are called for. Along the disease trajectory of high-grade glioma (HGG), patients are presented with a series of treatment decisions. At the same time, HGG patients often experience cognitive deterioration and reduced decision-making capacity. This study aimed to review the current knowledge about shared decision making from the perspective of the HGG patient. METHODS: Systematic searches were performed in MEDLINE, CINAHL, PsycINFO, and EMBASE. Studies were reviewed against the inclusion criteria and assessed for methodological quality. Descriptive data from the included studies were extracted and a narrative synthesis of the findings was performed. RESULTS: The searches resulted in 5051 original records. Four studies involving 178 HGG patients fulfilled the inclusion criteria. The narrative synthesis revealed that most HGG patients in the included studies appreciated an SDM approach and that sufficient information and involvement increased patients' emotional well-being. The use of a patient decision aid showed the potential to increase knowledge, decrease uncertainty, and affect the treatment decision making of HGG patients. CONCLUSION: The results indicate that many HGG patients prefer an SDM approach and that SDM can lead patients toward improved emotional well-being. The evidence is weak, however, and firm conclusions and practice guidelines concerning SDM in HGG patients cannot be made. Future research is warranted to improve decision support for HGG patients.

Blood natural killer cells during treatment in recurrent ovarian cancer.

OBJECTIVE: Recent research indicated favorable prognostic impact of intratumoral natural killer (NK) cells in ovarian carcinoma (OC). The role of NK cells during chemotherapy in OC is unknown. We investigated impact of NK cells in OC patients treated with palliative chemotherapy. METHODS: Participants receiving palliative chemotherapy for recurrent OC (N = 72) had prospectively blood samples at baseline and before cycle 2. NK cell counts were quantified by flow cytometry. NK cell activity was measured by the NK Vue® assay, estimating interferon-gamma production. Overall survival (OS) was the primary endpoint. Cutoffs were predefined, NK numbers (≥184 × 106 cells/L vs. <184 × 106 cells/L) and NK activity (<200 pg/mL vs. ≥200 pg/mL). RESULTS: Median OS in patients with low vs. high NK cell count at baseline was 7.1 months vs. 15.6 months (p = .028), respectively, and before cycle 2 was 5.7 vs. 17.3 months, p < .001, respectively. The difference in restricted mean survival (ΔRMST) was 5.7 months (95% CI: 3.3-8.0) at cycle 2 vs. 2.5 months (95% CI: -0.6 to 5.6) at baseline, showing a significant difference with no overlap of confidence intervals. In multivariate analyses, low NK cell count remained significant with a hazard ratio (HR)=2.83, 95% CI: 1.53-5.22, p = .001 (baseline) and HR = 3.34, 95% CI: 1.67-6.71, p = .001 (before cycle 2). Patients with both low NK count and NK activity at baseline (N = 20) had median OS 6.5 months vs. 11.5 months in patients with either high activity, high count or both (p = .007). In parallel, patients with both low NK activity and count at cycle 2 (N = 18) had a median survival of 4.0 months vs. 15.4 months (p < .001). CONCLUSIONS: A low blood NK cell count in recurrent metastatic ovarian cancer during chemotherapy is associated with unfavorable prognostic impact. Early increase in survival difference based on NK cell status suggests an association between NK cell count and treatment benefit.

Favorable prognostic impact of Natural Killer cells and T cells in high-grade serous ovarian carcinoma.

Introduction: The aim of the present study was to investigate the prognostic impact of intratumoral cytotoxic T cells, Natural Killer (NK) cells, neutrophils and PD-L1 expression in patients with epithelial ovarian cancer.Methods: All patients diagnosed with high-grade serous carcinoma (HGSC) in Denmark in 2005 were included in the study. Immunohistochemical staining for PD-L1, CD8, CD66b and CD57 was performed on tumor tissue from 283 patients. Cell densities were analyzed using a digital image analysis method. The primary endpoint was overall survival (OS).Results: The median OS for HGSC patients was 30 months. It was 45 months in patients with high level of CD57+ NK cells (≥10 cells/mm2) compared with 29 month in patients with low level (<10 cells/mm2) (p = .0310). The median OS was 37 and 25 months in patients with high vs. low level of CD8+ T cells (cutoff 80 cells/mm2) (p = .0008). In multivariate analysis, high numbers of CD57+ NK cells and CD8+ T cells remained independent markers of favorable OS, adjusted hazard ratio (HR) 0.67; p = .041, and HR 0.72; p = .020, respectively. PD-L1 expression was associated with improved OS (37 months vs. 22 months, p = .0006), but was only borderline significant in the multivariate analysis (HR 0.77, p = .061). CD66b + neutrophils had no association with OS.Conclusions: In patients with HGSC tumor-infiltrating CD57+ NK cells and CD8+ T cells had favorable prognostic impact, while PD-L1 expression had borderline favorable prognostic significance. CD66b + neutrophils had no prognostic association. These findings may influence future immunotherapy development.

Characteristics of patients with cervical cancer during pregnancy: a multicenter matched cohort study. An initiative from the International Network on Cancer, Infertility and Pregnancy.

BACKGROUND: Treatment of cervical cancer during pregnancy is often complex and challenging. This study aimed to analyze current patterns of practice in the management of pregnant patients diagnosed with cervical cancer. METHODS: This was a matched cohort study comprising patients managed for cervical cancer during pregnancy from six European centers. Patient information was retrieved from the dataset of the International Network for Cancer, Infertility and Pregnancy from 1990 to 2012. Each center matched its patients with two non-pregnant controls for age (±5 years) and International Federation of Gynecology and Obstetrics (FIGO) 2009 stage. Information on age, histological type, grade, lymphovascular space invasion, stage, tumor size, method of diagnosis, site of recurrence, delivery, date of recurrence, and date of death was recorded. Progression-free survival was compared using multivariable Cox proportional hazards regression. RESULTS: A total of 132 pregnant patients and 256 controls were analyzed. The pregnant patients (median age 34 years, range 21-43) were diagnosed at a median gestational age of 18.4 weeks of pregnancy (range 7-39). Stage distribution during pregnancy was 14.4% for stage IA, 47.0% for IB1, 18.9% for IB2, and 19.7% for II-IV. For treatment during pregnancy, 17.4% of the patients underwent surgery, 16.7% received neoadjuvant chemotherapy, 26.5% delayed their treatment, 12.9% had a premature delivery, and 26.5% had their pregnancy terminated. Median follow-up was 84 months (67 months for pregnant and 95 months for non-pregnant patients). The unadjusted hazard ratio of pregnancy for progression-free survival was 1.18 (95% confidence interval 0.74 to 1.88). CONCLUSION: Surgery and chemotherapy is increasingly used in the management of pregnant patients with cervical cancer and prognosis is similar to that of non-pregnant patients.

The clinical importance of BRCAness in a population-based cohort of Danish epithelial ovarian cancer.

OBJECTIVE: Germline mutations in BRCA1/2 genes predict improved survival and sensitivity to treatment with poly(adenosine-diphosphate-ribose) polymerase inhibitors in epithelial ovarian carcinoma. The prognostic importance of other genetic alterations leading to homologous recombination deficiency, collectively BRCAness phenotype, is unresolved. The aim was to analyze the distribution of homologous recombination deficiency in epithelial ovarian carcinoma caused by mutations in a panel of homologous recombination genes (including BRCA1/2) or epigenetic alterations. A further aim was to investigate the prognostic importance of homologous recombination deficiency, the BRCAness phenotype. METHODS: We assessed 380 patient specimens from a Danish population-based epithelial ovarian carcinoma cohort for germline and somatic mutations in 18 different homologous recombination genes, including BRCA1 and BRCA2, using next generation sequencing. Epigenetic alteration due to BRCA1 hypermethylation was assessed by pyrosequencing and BRCA1 protein expression was evaluated by immunohistochemistry. RESULTS: Seventeen percent of patients with epithelial ovarian carcinoma carried a germline (9.8%) and/or somatic (6.3%) mutation in 12 (BRCA1, BRCA2, CHEK2, ATM, RAD51D, EMSY, PALB2, BRIP1, ERCC1, RAD50, ATR, RAD51C) of 18 sequenced homologous recombination genes. The homologous recombination mutation rate was similar among the different histologic subtypes, however the type of mutation (BRCA1/2 and other homologous recombination mutations) differed, p=4×10-4. BRCA1 hypermethylation was present in 7.4% of patient specimens for a total BRCAness phenotype of 23.9%. The BRCAness phenotype was associated with improved overall survival in the high-grade serous carcinoma subgroup with a median overall survival of 4.4 years (95% CI 3.0 to 5.3) versus 2.2 years (95% CI 1.9 to 2.4) in BRCAness wildtype, p=0.0002. Multivariate analysis confirmed an independent prognostic value of the BRCAness phenotype among the high-grade serous carcinoma subgroup, hazard ratio 0.65 (95% CI 0.47 to 0.92), p=0.014. CONCLUSIONS: The BRCAness phenotype is present in almost one-fourth of epithelial ovarian carcinoma and holds important prognostic information. The implications of our findings in relation to poly(adenosine-diphosphate-ribose) polymerase inhibitor treatment call for further investigation.

Oncological management and obstetric and neonatal outcomes for women diagnosed with cancer during pregnancy: a 20-year international cohort study of 1170 patients.

BACKGROUND: Awareness is growing that cancer can be treated during pregnancy, but the effect of this change on maternal and neonatal outcomes is unknown. The International Network on Cancer, Infertility and Pregnancy (INCIP) registers the incidence and maternal, obstetric, oncological, and neonatal outcomes of cancer occurring during pregnancy. We aimed to describe the oncological management and obstetric and neonatal outcomes of patients registered in INCIP and treated in the past 20 years, and assess associations between cancer type or treatment modality and obstetric and neonatal outcomes. METHODS: This descriptive cohort study included pregnant patients with cancer registered from all 37 centres (from 16 countries) participating in the INCIP registry. Oncological, obstetric, and neonatal outcome data of consecutive patients diagnosed with primary invasive cancer during pregnancy between Jan 1, 1996, and Nov 1, 2016, were retrospectively and prospectively collected. We analysed changes over time in categorical patient characteristics, outcomes, and treatment methods with log-binomial regression. We used multiple logistic regression to analyse preterm, prelabour rupture of membranes (PPROM) or preterm contractions, small for gestational age, and admission to the neonatal intensive care unit (NICU). The INCIP registry study is registered with ClinicalTrials.gov, number NCT00330447, and is ongoing. FINDINGS: 1170 patients were included in the analysis and 779 (67%) received treatment during pregnancy. Breast cancer was the most common malignant disease (462 [39%]). Every 5 years, the likelihood of receiving treatment during pregnancy increased (relative risk [RR] 1·10, 95% CI 1·05-1·15), mainly related to an increase of chemotherapeutic treatment (1·31, 1·20-1·43). Overall, 955 (88%) of 1089 singleton pregnancies ended in a livebirth, of which 430 (48%) of 887 pregnancies ended preterm. Each 5 years, we observed more livebirths (RR 1·04, 95% CI 1·01-1·06) and fewer iatrogenic preterm deliveries (0·91, 0·84-0·98). Our data suggest a relationship between platinum-based chemotherapy and small for gestational age (odds ratio [OR] 3·12, 95% CI 1·45-6·70), and between taxane chemotherapy and NICU admission (OR 2·37, 95% CI 1·31-4·28). NICU admission seemed to depend on cancer type, with gastrointestinal cancers having highest risk (OR 7·13, 95% CI 2·86-17·7) and thyroid cancers having lowest risk (0·14, 0·02-0·90) when compared with breast cancer. Unexpectedly, the data suggested that abdominal or cervical surgery was associated with a reduced likelihood of NICU admission (OR 0·30, 95% CI 0·17-0·55). Other associations between treatment or cancer type and outcomes were less clear. INTERPRETATION: Over the years, the proportion of patients with cancer during pregnancy who received antenatal treatment increased, especially treatment with chemotherapy. Our data indicate that babies exposed to antenatal chemotherapy might be more likely to develop complications, specifically small for gestational age and NICU admission, than babies not exposed. We therefore recommend involving hospitals with obstetric high-care units in the management of these patients.

Maternal and obstetrical outcome in 35 cases of well-differentiated thyroid carcinoma during pregnancy.

OBJECTIVES/HYPOTHESIS: Thyroid cancer, with 6% to 10% of cancer diagnoses, is one of the most common malignancies during pregnancy. Its treatment poses a risk for the pregnancy, as the thyroid gland plays a crucial role in the evolution of pregnancy. The aim of this study is to evaluate treatment of primary well-differentiated thyroid carcinoma during pregnancy and fetal and maternal outcomes. STUDY DESIGN: This is an international cohort study. METHODS: Primary thyroid cancer patients were identified from the database of the International Network on Cancer, Infertility, and Pregnancy registration study. Data on histopathological characteristics, diagnostic and therapeutic interventions, outcome (obstetrical, neonatal, and maternal) and maternal follow-up were analyzed. RESULTS: Thirty-five patients with well-differentiated thyroid carcinoma were eligible. All 35 patients underwent surgery, 29 (83%) of which during pregnancy. Procedures during pregnancy were mainly total thyroidectomies (n = 24). The median number of days between diagnosis and surgical treatment was different between the groups with surgery during and after pregnancy (27 vs. 139 days, P < .001). Both maternal and neonatal outcomes were uncomplicated, regardless of gestational age during surgery. CONCLUSIONS: Well-differentiated thyroid carcinoma diagnosed during pregnancy has a favorable outcome for both mother and child. Surgical management during pregnancy has no negative impact on the pregnancy regardless of the trimester at the time of surgery. However, the potential negative effects of thyroid surgery early in pregnancy demand management of these patients in an experienced multidisciplinary team to provide the best possible care for these patients and their unborn babies.

Implementing shared decision making in Denmark: First steps and future focus areas.

What about the political climate? Although there is no explicit description of patient involvement in Danish legislation, patient-centred care is on the political agenda in Denmark. It is integrated as one of eight new national indicators of quality in health care, as well as in the most recent national plan for cancer treatment. What about tools for patient decision support? Development of evidence-based patient decision aids (PDAs) are still at an early stage in Denmark, but recent national and private funding has helped push the field forward. Furthermore, a few stakeholders have started working more systematically with developing and testing PDAs in clinical settings. What about implementation? There is growing interest among Danish health care professionals, but SDM is still far from standard practice in Denmark. Although some courses in SDM and use of PDAs now exist, few health care professionals have received systematic training, and there is little knowledge about implementation and sustainability of SDM in daily clinical practice. What does the future look like for SDM in Denmark? Future progress will depend on the extent to which SDM is systematically integrated in the daily routines of health care professionals and in patient trajectories across treatment courses. The Danish health care system needs to invest further in training and to start addressing the challenges on the organisational and system level, which affect implementation.

Melanoma during pregnancy: a report of 60 pregnancies complicated by melanoma.

The management of melanoma during pregnancy is challenging as maternal benefits and fetal risks need to be balanced. Here, we present an overview of the incidence, the demographic and clinical characteristics and the treatment modalities used. After analysis of obstetric, fetal and maternal outcome, recommendations for clinical practice are provided. From the 'International Network on Cancer, Infertility and Pregnancy' database, pregnant patients with melanoma were identified and analysed. Sixty pregnancies were eligible for analysis. Fifty percent of the patients presented with advanced melanoma during pregnancy (14 stage III and 16 stage IV), and 27% were diagnosed with recurrent melanoma. Surgery was the main therapeutic strategy during pregnancy. Only four patients with advanced melanoma were treated during pregnancy with systemic therapy (n=1) or radiotherapy (n=3). Premature delivery was observed in 18% of the ongoing pregnancies, all which were induced and 78% of which involved patients with advanced melanoma. Thirty-nine percent of the patients died within 5 years; all had been diagnosed with stage III or IV disease during pregnancy. Melanoma can present in a more advanced stage during pregnancy. New systemic therapies may be beneficial for patients with metastatic melanoma but may not be pregnancy compatible. In these patients, preterm induction of labour need to be discussed, despite the short-term and long-term negative effects on the child.

The Prognostic Value of BRCA1 and PARP Expression in Epithelial Ovarian Carcinoma: Immunohistochemical Detection.

BRCA1/2 mutation status in epithelial ovarian cancer (EOC) presently relies on genetic testing which is resource consuming. Immunohistochemistry is cheap, fairly reproducible, and may identify gene product alterations due to both germline and somatic mutations and other defects along the BRCA gene pathway (BRCAness phenomenon), which is important when treatment with poly (adenosine-diphosphate-ribose) polymerase (PARP) inhibitors is considered. The aim of this study was to investigate immunohistochemical detection of BRCA1 and PARP expression in EOC and their possible prognostic relevance. Tumor tissue from 170 patients with EOC was stained immunohistochemically with BRCA1 and PARP antibodies. Semiquantitative analyses were performed to determine loss of, equivocal, and retained BRCA1 and high versus low PARP protein expression. These parameters were analyzed for relation with patient and clinicopathologic characteristics and overall survival. BRCA1 expression was reduced in 21.2 % of the tumors and 36.5% showed high PARP expression. No correlation between the 2 parameters or between PARP and clinicopathologic features was found. Overall survival was significantly increased in the BRCA1-reduced and equivocal groups [median survival 2.4 y (95% CI, 1.6-6.6) and 4.9 y (95 % CI, 2.3-6.7) vs. 1.5 y (95% CI, 1.3-1.9); P=0.0002]. Multivariate analysis confirmed these findings; hazard ratio=0.53 (95% CI, 0.34-0.81; P=0.0037; loss of BRCA1 expression). In conclusion, immunohistochemical BRCA1 expression in EOC holds considerable prognostic information, whereas PARP expression did not influence the outcome. The results call for validation in prospective trials.

Primary brain tumours, meningiomas and brain metastases in pregnancy: report on 27 cases and review of literature.

BACKGROUND: The concurrence of intracranial tumours with pregnancy is rare. The purpose of this study was to describe all reported patients registered in the international Cancer in Pregnancy registration study (CIP study; http://www.cancerinpregnancy.org), and to review the literature in order to obtain better insight into outcome and possibilities of treatment in pregnancy. METHODS: We collected all intracranial tumours (primary brain tumour, cerebral metastasis, or meningioma) diagnosed during pregnancy, registered prospectively and retrospectively by international collaboration since 1973. Patients diagnosed postpartum were excluded. We summarised the demographic features, treatment decisions, obstetrical and neonatal outcomes. RESULTS: The mean age of the 27 eligible patients was 31years (range 23-41years), of which 13 and 12 patients were diagnosed in the second and third trimesters, respectively. Eight patients (30%) underwent brain surgery, seven patients (26%) had radiotherapy and in three patients (11%) chemotherapy was administered during gestation. Two patients died during pregnancy and four pregnancies were terminated. In 16 (59%) patients elective caesarean section was performed of which 14 (52%) were still preterm (range 30-36weeks, mean 33weeks). Five patients had a vaginal delivery (range 36-40weeks). Of the 21 ongoing pregnancies all children were born alive without visible congenital malformations and the available long-term follow-up data (range 2-25years) of six children were reassuring. CONCLUSION: Adherence to standard protocol for the treatment of brain tumours during pregnancy appears to allow a term delivery and a higher probability of a vaginal delivery.

Gynecologic cancers in pregnancy: guidelines of a second international consensus meeting.

OBJECTIVES: This study aimed to provide timely and effective guidance for pregnant women and health care providers to optimize maternal treatment and fetal protection and to promote effective management of the mother, fetus, and neonate when administering potentially teratogenic medications. New insights and more experience were gained since the first consensus meeting 5 years ago. METHODS: Members of the European Society of Gynecological Oncology task force "Cancer in Pregnancy" in concert with other international experts reviewed the existing literature on their respective areas of expertise. The summaries were subsequently merged into a complete article that served as a basis for discussion during the consensus meeting. All participants approved the final article. RESULTS: In the experts' view, cancer can be successfully treated during pregnancy in collaboration with a multidisciplinary team, optimizing maternal treatment while considering fetal safety. To maximize the maternal outcome, cancer treatment should follow a standard treatment protocol as for nonpregnant patients. Iatrogenic prematurity should be avoided. Individualization of treatment and effective psychologic support is imperative to provide throughout the pregnancy period. Diagnostic procedures, including staging examinations and imaging, such as magnetic resonance imaging and sonography, are preferable. Pelvic surgery, either open or laparoscopic, as part of a treatment protocol, may reveal beneficial outcomes and is preferably performed by experts. Most standard regimens of chemotherapy can be administered from 14 weeks gestational age onward. Apart from cervical and vulvar cancer, as well as important vulvar scarring, the mode of delivery is determined by the obstetrician. Term delivery is aimed for. Breast-feeding should be considered based on individual drug safety and neonatologist-breast-feeding expert's consult. CONCLUSIONS: Despite limited evidence-based information, cancer treatment during pregnancy can succeed. State-of-the-art treatment should be provided for this vulnerable population to preserve maternal and fetal prognosis. SUPPLEMENTARY INFORMATION: Supplementary data on teratogenic effects, ionizing examinations, sentinel lymph node biopsy, tumor markers during pregnancy, as well as additional references and tables are available at the extended online version of this consensus article, go to http://links.lww.com/IGC/A197.

Immunohistochemical expression of platelet-derived growth factor receptors in ovarian cancer patients with long-term follow-up.

Introduction. The well-documented role of the PDGF system in tumor growth and angiogenesis has prompted the development of new biological agents targeting the PDGF system. The aim of the present study was to analyze the expression of the PDGF-receptors in ovarian cancer and to investigate its relation to histopathological parameters and long-term overall survival. Methods. The immunohistochemical expression of PDGFR-α and PDGFR-ß was investigated in tumor and stromal cells in 170 patients with histologically verified epithelial ovarian cancer. Results. Almost half of the tumor specimens showed high expression of PDGFR-α and PDGFR-ß in tumor cells (43% and 41%) and in stromal compartments (32% and 44%). There was a significant association between high expression of PDGFR-α and high expression of PDGFR-ß in both tumor and stromal cells. Coexpression of PDGFR-α and PDGFR-ß in stromal cells was seen more often in serous adenocarcinomas than in nonserous adenocarcinomas. No clear correlation between PDGFR expression and longterm overall survival or clinical parameters was found. Conclusions. PDGFR-α and PDGFR-ß were expressed in a subset of ovarian carcinomas but did not show significant prognostic importance in this material.
