RESUMO

BACKGROUND: Guidelines recommend to include exercise and dietary advice in standard care for patients with cancer, based on evidence primarily derived from patients with breast cancer. Its applicability to patients with ovarian cancer is uncertain due to differences in patient characteristics and treatments. The PADOVA trial examined the effectiveness of a combined exercise and dietary intervention on fat-free mass (FFM), physical functioning, and fatigue. METHODS: In total, 81 patients with ovarian cancer were randomised to the exercise and dietary intervention (n = 40) or control (n = 41) group. Measurements were performed before chemotherapy, after chemotherapy, and 12 weeks later. FFM was assessed by bioelectrical impedance analysis, and physical functioning and fatigue were assessed using questionnaires. Intervention effects were assessed on an intention-to-treat basis using linear mixed models. RESULTS: FFM and physical functioning increased, and fatigue decreased significantly over time in both groups. No significant difference between the groups were found for FFM (ß = -0.5 kg; 95% CI = -3.2; 2.1), physical functioning (ß = 1.4; 95% CI = -5.4; 8.3) and fatigue (ß = 0.7; 95% CI = -1.5; 2.8). CONCLUSIONS: During treatment, both groups improved in FFM, physical functioning, and fatigue. The intervention group, however, did not demonstrate additional benefits compared to the control group. This highlights the need for caution when extrapolating findings from different cancer populations to patients with ovarian cancer.

RESUMO

OBJECTIVE: To study physical activity and dietary intake among patients with ovarian cancer and to examine which demographic, clinical, and sociocognitive determinants are associated with these behaviours. METHODS: This cross-sectional study included 139 patients with ovarian cancer scheduled for (neo)adjuvant chemotherapy. Physical activity was measured with the Physical Activity Scale for the Elderly questionnaire (PASE). Dietary intake was measured with a questionnaire assessing energy and protein intake and a questionnaire assessing adherence to the World Cancer Research Fund (WCRF) lifestyle recommendations. Demographic, clinical, and sociocognitive (e.g., self-efficacy) determinants of physical activity and dietary intake were examined using backward linear regression analyses. RESULTS: Patients reported a median PASE score of 50 (IQR 24-94), a mean ± SD dietary intake of 1831 ± 604 kcal/day and 76 ± 27 g protein/day. Patients adhered to 3 out of 5 WCRF lifestyle recommendations. The absence of comorbidities, lower physical outcome expectations, and higher cancer specific outcome expectations were independently associated with higher physical activity levels. Higher age, lower cancer specific outcome expectations, and higher diet-related self-efficacy were significantly associated with adhering to more WCRF lifestyle recommendations, whilst no variables associated with total caloric or protein intake were identified. CONCLUSIONS: Patients with ovarian cancer have low physical activity levels and a suboptimal diet, particularly low fruit and vegetable consumption and dietary fibre intake. Interventions aiming to improve physical activity and dietary intake could focus on increasing self-efficacy and outcome expectations, and should consider age and comorbidity as factors that may impact behaviour.

RESUMO

OBJECTIVE: Gestational trophoblastic diseases (GTD) comprise a group of rare diseases originating from the trophoblast affecting women of childbearing age. Providing optimal information to patients with a rare disease is challenging because of the small number of patients and limited clinical expertise of many healthcare professionals. Both knowledge and lack of knowledge in patients may influence illness perception. We investigated whether a web-based interactive intervention influences illness perception and knowledge in women with GTD. DESIGN: This was a multicenter randomized control trial conducted at general and academic hospitals in the Netherlands, including newly diagnosed GTD patients between 2017 and 2019. METHODS: Sixty-nine patients were randomized between direct access or postponed access to an online tool on GTD and received online questionnaires about illness perception, knowledge, and anxiety. The main outcome measures were illness perception (primary outcome measure) and knowledge (secondary outcome measure). RESULTS: Patients using the online tool were satisfied with the information from the tool (92%). Although they had a higher level of knowledge compared to the control group (p = 0.006), illness perception did not change. Also, no differences in levels of anxiety, depression, or distress were observed between the groups. LIMITATIONS: Participants had access to other information sources and many searched other websites. It is unknown what kind of websites were visited and when. It is unknown if the increased knowledge levels and low levels of distress will sustain over time as no long term follow-up took place. Healthcare professionals were not interviewed on how they experienced the consultation before and after using the tool by the patients. CONCLUSIONS: The online tool did not change illness perception but was shown to be valuable for newly diagnosed GTD patients to gain knowledge. The improvement in knowledge after digital education indicates that this tool can be used as an effective method of supporting GTD patients' informational needs without causing extra distress. TWEETABLE ABSTRACT: A web-based tool for trophoblastic disease does not change illness perception of patients but is valuable to gain knowledge.

RESUMO

INTRODUCTION: Adoptive cellular immunotherapy could be an interesting new treatment option for ovarian carcinoma (OC), as research has demonstrated that OC is an immunogenic disease. In particular, natural killer (NK) cells have attracted attention due to their ability to kill tumor cells without prior sensitization. The therapeutic value of allogeneic NK cells has been first observed in hematological cancers and is increasingly being explored in solid tumors. METHODS: To substantiate the rationale for NK cell therapy in OC we performed a literature search in the Pubmed database and in the international trial register clinicaltrials.gov with attention for the effect of OC on NK cell function, the effect of current treatment on NK cell biology and the evidence on the therapeutic value of NK cell therapy against OC. RESULTS: In six clinical trials only 31 OC patients have been reported that received NK cell adoptive transfer. The majority of patients reached stable disease after NK cell therapy, with a mild pattern of side effects. In patients who received repeated infusions, more complete responses are described. All reported studies investigated the intravenous infusion of NK cells. Whereas the studies that are currently recruiting, investigate intraperitoneal infusion of allogeneic NK cells. CONCLUSION: In this review the pre-clinical evidence and current trials on NK cell immunotherapy in OC patients are summarized. Furthermore, challenges that have to be overcome for NK cell adoptive therapy to have a significant impact on disease outcome are discussed.

RESUMO

BACKGROUND: The main data available on the safety of radiation during pregnancy originate from animal studies and from studies of survivors of atomic or nuclear disasters. The effect of radiotherapy to treat maternal cancer on fetal development is uncertain. This report presents a unique cohort and aims to determine the long-term neurocognitive, psychosocial and physical outcomes of offspring of mothers treated with radiotherapy during pregnancy. METHODS: In this international, multicentre, mixed retrospective-prospective cohort study, we recruited participants between Aug 5, 2006, and Aug 24, 2023, aged between 1·5 and 46 years, at three referral centres in Belgium, the Netherlands, and the USA. Participants were eligible if they were born from mothers treated with radiotherapy during pregnancy. Fetal radiation doses were obtained from medical records and participants were followed up at predefined ages (1·5, 3, 6, 9, 12, 15, and 18 years) and 5-yearly in adulthood, based on age at enrolment, using a neurocognitive test battery (measuring intelligence, attention, and memory), parent-reported executive function and psychosocial questionnaires, and a medical assessment. Results were compared with test-specific normative data. Linear regression models investigated associations between radiotherapy factors (fetal radiation dose, gestational age at the start and end of radiotherapy, and radiotherapy duration) and outcomes. FINDINGS: 68 maternal cases of radiotherapy during pregnancy were registered by the three participating centres, of which 61 resulted in a livebirth and were therefore eligible to participate in the child follow-up study. After excluding those who did not give consent, 43 participants born from 42 mothers treated with radiotherapy during pregnancy were included in the study (median age at first assessment 3 years [IQR 2-11]; median age at last assessment 12 years [9-18]; median number of assessments two [1-4]). 18 (42%) of the included participants were female and 25 (58%) male, and 37 (86%) were of White ethnicity. Mean neurocognitive outcomes of the entire cohort were within normal ranges. No associations were found with fetal radiation dose or timing of radiotherapy during pregnancy. Six (16%) of 38 participants with neurocognitive outcomes scored lower than one SD on at least one neurocognitive outcome, three (7%) reported chronic medical conditions (spasmophilia, spastic diplegia, and IgG deficiency), and three (7%) were diagnosed with attention-deficit hyperactivity disorder (of whom two scored lower on attention). Of ten (23%) participants with lower neurocognitive score(s), a chronic medical condition, or attention-deficit hyperactivity disorder, eight were born preterm. The remaining 33 (77%) participants showed no neurocognitive, psychosocial, or chronic physical problems. INTERPRETATION: We show on average normal neurocognitive, psychosocial, and physical outcomes after prenatal exposure to radiotherapy. Differences in outcomes could not be explained by exposure to radiotherapy during pregnancy. These results suggest that extra-abdomino-pelvic radiotherapy exposure during pregnancy in general does not adversely affect outcomes of liveborn children. Further research with a larger sample is necessary to confirm these findings. FUNDING: Kom Op Tegen Kanker, KWF Kankerbestrijding, Stichting Tegen Kanker, Research Foundation Flanders.

RESUMO

Chemotherapy and particularly anthracycline exposure are associated with acute and chronic cardiotoxicity. Few data exist on the effect of cardiac function after in utero exposure to maternal chemotherapy. Our recently published multicenter prospective study showed no significant changes in systolic function using conventional echocardiographic parameters. The purpose of this study was to further investigate whether early functional changes can be detected using tissue Doppler imaging (TDI) and two-dimensional (2D) speckle tracking echocardiography (STE). Sixty-two children (median/range age 1.7 (1-9.8) years) exposed to chemotherapy during fetal life were enrolled and compared to 62 age- and gender-matched controls. TDI velocities were measured at the basal interventricular septum (IVS) and right and left ventricular (LV) free walls. LV global longitudinal and circumferential systolic strains were derived using 2D STE. We found small but significant differences between the groups (patients versus controls) in LV fractional shortening [35 (29-46)% versus 39 (28-53)%, p < 0.001], LV ejection fraction [66 (57-79)% versus 70 (57-83)%, p < 0.001], LV posterior wall thickness z score [-0.15 (-2.32-1.81) versus -0.10 (-1.9-2.0), p < 0.001], and IVS thickness z score [-1.06 (-2.6-1.3) versus -0.5 (-2.1-1.7), p < 0.001]. No significant differences in TDI velocities or LV global strains were observed. Within the patient group, the cardiac functional parameters did not correlate to the number of cycles of anthracycline or the cumulative anthracycline dose. Children exposed to fetal chemotherapy have a lower normal fractional shortening and mildly lower left ventricular wall thickness. Tissue Doppler and strain measurements are within normal range and not statistically different from normal controls. The long-term implications of these findings will be further studied in this prospective cohort study.

RESUMO

PURPOSE: This multicenter trial by the European Organisation for Research and Treatment of Cancer Gynecological Cancer Group was motivated by conflicting evidence on the value of neoadjuvant chemotherapy before surgery compared with concomitant chemoradiotherapy (CCRT) in stage IB2-IIB cervical carcinoma. METHODS: Between May 2002 and January 2014, 626 patients with International Federation of Gynecology and Obstetrics stage IB2-IIb were randomly assigned between neoadjuvant chemotherapy followed by surgery (NACT-S; n = 314) and standard CCRT (n = 312). The primary end point was 5-year overall survival (OS) rate. Secondary end points were progression-free survival, OS, toxicity, and health-related quality of life (HRQOL). RESULTS: After a median follow-up of 8.7 years, 198 patients (31.6%) died. Age, stage, and cell type were balanced in both arms. Protocol treatment was completed in 223 of 314 (71%) patients in NACT-S and 257 of 312(82%) in CCRT arms. Main reasons for incomplete protocol treatment were toxicity (30 of 314; 9.6%) and progressive disease (21 of 314; 6.7%) in the NACT-S arm and toxicity (23 of 312; 7.4%) and patient refusal (13 of 312; 4.2%) in the CCRT arm. Additional radiotherapy after completed NACT-S was given to 107 patients (48%), and additional surgery to 20 patients (8%) after completed CCRT. Short-term adverse events (AEs) ≥grade 3 occurred more frequently with NACT-S (41% v 23%), and long-term AEs ≥grade 3 more often with CCRT (21% v 15%). The 5-year OS was not significantly different between NACT-S (72%; 95% CI, 66 to 77) and CCRT (76%; 95% CI, 70 to 80). CONCLUSION: This trial failed to demonstrate superiority in favor of the NACT-S arm but resulted in acceptable morbidity and HRQOL in both arms.

RESUMO

PURPOSE: Tissue factor is highly expressed in cervical carcinoma and can be targeted by tisotumab vedotin (TV), an antibody-drug conjugate. This phase Ib/II study evaluated TV in combination with bevacizumab, pembrolizumab, or carboplatin for recurrent or metastatic cervical cancer (r/mCC). METHODS: This open-label, multicenter study (ClinicalTrials.gov identifier: NCT03786081) included dose-escalation arms that assessed dose-limiting toxicities (DLTs) and identified the recommended phase II dose (RP2D) of TV in combination with bevacizumab (arm A), pembrolizumab (arm B), or carboplatin (arm C). The dose-expansion arms evaluated TV antitumor activity and safety at RP2D in combination with carboplatin as first-line (1L) treatment (arm D) or with pembrolizumab as 1L (arm E) or second-/third-line (2L/3L) treatment (arm F). The primary end point of dose expansion was objective response rate (ORR). RESULTS: A total of 142 patients were enrolled. In dose escalation (n = 41), no DLTs were observed; the RP2D was TV 2 mg/kg plus bevacizumab 15 mg/kg on day 1 once every 3 weeks, pembrolizumab 200 mg on day 1 once every 3 weeks, or carboplatin AUC 5 on day 1 once every 3 weeks. In dose expansion (n = 101), the ORR was 54.5% (n/N, 18/33; 95% CI, 36.4 to 71.9) with 1L TV + carboplatin (arm D), 40.6% (n/N, 13/32; 95% CI, 23.7 to 59.4) with 1L TV + pembrolizumab (arm E), and 35.3% (12/34; 19.7 to 53.5) with 2L/3L TV + pembrolizumab (arm F). The median duration of response was 8.6 months, not reached, and 14.1 months, in arms D, E, and F, respectively. Grade ≥3 adverse events (≥15%) were anemia, diarrhea, nausea, and thrombocytopenia in arm D and anemia in arm F (none ≥15%, arm E). CONCLUSION: TV in combination with bevacizumab, carboplatin, or pembrolizumab demonstrated manageable safety and encouraging antitumor activity in treatment-naive and previously treated r/mCC.

RESUMO

There is now a greater understanding of the molecular pathways in ovarian cancer, and using this knowledge, a large number of new therapeutic agents can be tested. The success of these drugs will depend on selecting drugs that target known key dysfunctional molecular pathways. To make best use of these compounds, prognostic and predictive biomarkers need to be identified. Novel methods of assessment such as functional imaging need to be developed as additional biological end points to evaluate these therapies. Promising antitumor activity has been observed with some drugs, and careful consideration is needed to determine in what circumstances new agents, such as antiangiogenic compounds, could be considered as a standard therapy. These areas were discussed at the 4th Ovarian Cancer Consensus Conference.

RESUMO

The treatment of recurrent endometrial cancer is a challenge. Because of earlier treatments and the site of locoregional recurrence, in the vaginal vault or pelvis, morbidity can be high. A total of about 4 to 20% of the patients with endometrial cancer develop a locoregional recurrence, mostly among patients with locally advanced disease. The treatment options are dependent on previous treatments and the site of recurrence. Local and locoregional recurrences can be treated curatively with surgery or (chemo)radiotherapy with acceptable toxicity and control rates. Distant recurrences can be treated with palliative systemic therapy, i.e., first-line chemotherapy or hormonal therapy. Based on the tumor characteristics and molecular profile, there can be a role for immunotherapy. The evidence on targeted therapy is limited, with no approved treatment in the current guidelines. In selected cases, there might be an indication for local treatment in oligometastatic disease. Because of the novel techniques in radiotherapy, disease control can often be achieved at limited toxicity. Further studies are warranted to analyze the survival outcome and toxicity of newer treatment strategies. Patient selection is very important in deciding which treatment is of most benefit, and better prediction models based on the patient- and tumor characteristics are necessary.

RESUMO

PURPOSE: The survival results of the PORTEC-3 trial showed a significant improvement in both overall and failure-free survival with chemoradiation therapy versus pelvic radiation therapy alone. The present analysis was performed to compare long-term adverse events (AE) and health-related quality of life (HRQOL). METHODS AND MATERIALS: In the study, 660 women with high-risk endometrial cancer were randomly assigned to receive chemoradiation therapy (2 concurrent cycles of cisplatin followed by 4 cycles of carboplatin/paclitaxel) or radiation therapy alone. Toxicity was graded using Common Terminology Criteria for Adverse Events, version 3.0. HRQOL was measured using EORTC QLQ-C30 and CX24/OV28 subscales and compared with normative data. An as-treated analysis was performed. RESULTS: Median follow-up was 74.6 months; 574 (87%) patients were evaluable for HRQOL. At 5 years, grade ≥2 AE were scored for 78 (38%) patients who had received chemoradiation therapy versus 46 (24%) who had received radiation therapy alone (P = .008). Grade 3 AE did not differ significantly between the groups (8% vs 5%, P = .18) at 5 years, and only one new late grade 4 toxicity had been reported. At 3 and 5 years, sensory neuropathy toxicity grade ≥2 persisted after chemoradiation therapy in 6% (vs 0% after radiation therapy, P < .001) and more patients reported significant tingling or numbness at HRQOL (27% vs 8%, P < .001 at 3 years; 24% vs 9%, P = .002 at 5 years). Up to 3 years, more patients who had chemoradiation therapy reported limb weakness (21% vs 5%, P < .001) and lower physical (79 vs 87, P < .001) and role functioning (78 vs 88, P < .001) scores. Both treatment groups reported similar long-term global health/quality of life scores, which were better than those of the normative population. CONCLUSIONS: This study shows a long-lasting, clinically relevant, negative impact of chemoradiation therapy on toxicity and HRQOL, most importantly persistent peripheral sensory neuropathy. Physical and role functioning impairments were seen until 3 years. These long-term data are essential for patient information and shared decision-making regarding adjuvant chemotherapy for high-risk endometrial cancer.

RESUMO

OBJECTIVE: To determine the impact of physiologic changes of pregnancy on pharmacokinetics of chemotherapeutic agents. DESIGN: A preclinical and a clinical case-control trial. SETTING: Institute of Primate Research Nairobi and collaborating hospitals in Belgium, the Netherlands and Czech Republic. POPULATION: Pregnant and nonpregnant women and baboons receiving chemotherapy. METHODS: Chemotherapy pharmacokinetics was compared between the pregnant and nonpregnant state. Standard-dosed chemotherapy regimens were administered in pregnant and nonpregnant baboons/women, followed by serial blood samplings. Drug plasma levels were determined using high performance liquid chromatography and atomic absorption spectrometry. MAIN OUTCOME MEASURES: Area under the curve (AUC), maximal plasma concentration, terminal elimination half-life, clearance and distribution volume of each drug in pregnant and nonpregnant state. RESULTS: Intraindividual comparative pharmacokinetic data were obtained for doxorubicin and paclitaxel/platinum in three and two baboons, respectively. In the clinical trial, two patients were exposed to doxorubicin and one patient was exposed to paclitaxel/platinum during and after pregnancy. Furthermore, a pooled analysis was performed based on 16 cycles of pregnant and 11 cycles of nonpregnant women. Numbers of pregnant/nonpregnant patients were 5/2, 7/5, 4/4 and 2/2 for paclitaxel, doxorubicin, epirubicin and platinum, respectively. For all drugs tested in the preclinical and clinical study, a decreased AUC and maximal plasma concentration and an increased distribution volume and clearance were observed in pregnancy. CONCLUSIONS: Although numbers were too small for statistical significance, pregnancy-associated physiologic alterations appear to lead to a decrease in plasma exposure of chemotherapeutic drugs. The importance of long-term follow-up of women treated with chemotherapy during pregnancy is underscored.

RESUMO

BACKGROUND: Gynecologic cancer during pregnancy is a special challenge because cancer or its treatment may affect not only the pregnant women in general but directly involve the reproductive tract and fetus. Currently, there are no guidelines on how to deal with this special coincidence. METHODS: An international consensus meeting on staging and treatment of gynecological malignancies during pregnancy was organised including a systematic literature search, and interpretation followed by a physical meeting of all participants with intensive discussion. In the absence of large trials and randomized studies, recommendations were based on available literature data and personal experience thus representing a low but best achievable level of evidence. FINDINGS: Randomized trials and prospective studies on cancer treatment during pregnancy are lacking. Gynecological cancer during pregnancy is a demanding problem, and multidisciplinary expertise should be available. Counseling both parents on the maternal prognosis and fetal risk is needed. When there is a firm desire to continue the pregnancy, gynecological cancer can be treated in selected cases. The staging and treatment should follow the standard approach as much as possible. Guidelines for safe pelvic surgery during pregnancy are presented. Mainly in cervical and ovarian cancer, chemotherapy and an alternative surgical approach need to be considered. Administration of chemotherapy during the second or third trimester may probably not increase the incidence of congenital malformations. Until now, the long-term outcome of children in utero exposed to oncological treatment modalities is poorly documented, but preterm birth on its own is associated with cognitive impairment. Delivery should be postponed preferably until after a gestational age of 35 weeks. INTERPRETATION: Further research including international registries for gynecologic cancer in pregnancy is urgently needed. The gathering of both available literature and personal experience allowed only suggesting models for treatment of gynecologic cancer in pregnancy.

RESUMO

INTRODUCTION: Recurrent ovarian carcinoma has dismal prognosis, but control of disease and prolonged survival are possible in some patients. The estimated 5-year survival is 46% for all stages of ovarian cancer, and only 28% for metastasized disease. Notably, the majority of women with ovarian cancer are diagnosed with stage III or IV disease with a high recurrence rate. As most women with relapsed or metastatic cancer will die of progressive disease, there is an urgent need for novel therapeutic strategies. The primary aim of our study is to evaluate safety and toxicity of intraperitoneal infusion of ex vivo-expanded natural killer cells (NK), generated from CD34+ umbilical cord blood (UCB) progenitor cells, with and without a preceding non-myeloablative immunosuppressive conditioning regimen in patients suffering from recurrent ovarian cancer. The secondary objectives are to compare the in vivo lifespan, expansion, and biological activity of intraperitoneally infused NK cell products with or without preparative chemotherapy, as well as evaluate effects on disease load. METHODS: In this phase I safety trial, 12 patients who are suffering from recurrent ovarian cancer, detected by a significant rise in serum level of CA-125 on two successive time points, will be included. Prior to UCB-NK cell infusion, a laparoscopy is performed to place a catheter in the peritoneal cavity. The first cohort of three patients will receive a single intraperitoneal infusion of 1.5-3×10 UCB-NK cells, generated ex vivo from CD34+ hematopoietic progenitor cells obtained from an allogeneic UCB unit, without a preparative chemotherapy regimen. The second group of three patients will be treated with a similar dose of UCB-NK cells following a preparative four days non-myeloablative immunosuppressive conditioning regimen with cyclophosphamide and fludarabine (Cy/Flu). If no severe toxicity is seen in these 6 patients, an extension cohort of 6 patients will be included to answer the secondary objectives. DISCUSSION: This study investigates the safety of a promising new cellular therapy in a group of patients with a poor prognosis. Demonstration of safety and in vivo expansion capacity of allogeneic UCB-NK cells in the absence of Cy/Flu pretreatment will provide rationale for UCB-NK cell infusion after regular second-line chemotherapy.

RESUMO

In this review current knowledge on prevalence, diagnosis, treatment and prognosis of gynaecological malignancies during pregnancy is discussed. After a general overview of surgery, chemotherapy and radiotherapy during pregnancy, tumor specific diagnosis and treatment options are described for breast, cervical, ovarian, endometrial and vulvar cancer. In contrast to previous belief, termination of pregnancy because of a concurrent malignancy does not result in an improved prognosis. Information on prognosis of cancer during pregnancy is often contradictory and evidence on the real influence of pregnancy on prognosis is weak. However, there is increasing belief that, the prognosis per stage is similar to that of the non-pregnant patient and that the risk for impaired prognosis is most likely due to suboptimal diagnosis and treatment. With the exception of pelvic surgery, most surgical techniques that are used in non-pregnant patients are also safe for pregnant patients. Radiotherapy proximal of the upper abdomen is frequently possible, while chemotherapy depending on pregnancy trimester and type of chemotherapy can usually be administered without much hazards. Indications for termination of pregnancy include an unwanted pregnancy and locally advanced cervical cancer. This group of patients is however very small, suggesting that mostly fetal life can be saved.

RESUMO

Newly developed treatment strategies for breast cancer have reduced mortality rates over the past decades. Patients with breast cancer represent a heterogeneous population. Differences in the severity of the disease require diverse treatment options. Women have distinct individual risk patterns for cardiovascular disease that may affect their susceptibility to cardiotoxicity during therapy. While breast cancer treatment is targeted more on tumor and patient characteristics, a tailored individual approach with early and late cardiosurveillance is not yet implemented in routine care. Newly available cardiac imaging techniques are better suited to the early detection of cardiotoxicity and should be used more often in those patients at highest risk, as the early intervention afforded will improve their quality of life and prognosis.

RESUMO

RATIONALE, AIMS AND OBJECTIVES: To develop a guideline with quality criteria for an optimal structure and functioning of a multidisciplinary team meeting (MTM), and to assess to what extent the Dutch MTMs complied with these criteria. METHOD: A literature search and expert opinions were used to develop a guideline for optimal MTMs. In order to assess adherence to the guideline, we conducted interviews with MTM chairs and observed general and tumour-specific MTMs in seven hospitals. RESULTS: The new guideline included the following domains: (i) organization of the MTMs; (ii) membership of the MTM and roles and responsibilities of the members; (iii) the meeting itself; and (iv) documentation of meeting-recommendations. We observed good adherence to the quality criteria on the organization of the MTMs. Only the required coordinator/administrative support was often absent, particularly during general MTMs. Regarding membership of MTMs and roles, the recommended average attendance of 100% of the core disciplines was never reached and particularly the role of the chair needs improvement. Regarding the meeting itself, many interruptions took place and relevant information about the diagnoses of the cases was not available in 4-5% of the cases. Concerning the documentation of meeting-recommendations, only in a quarter of the meetings a specific form was used for the documentation. CONCLUSIONS: We found a lot of diversity in the organization of MTMs. The variation in compliance with the quality criteria may decrease with better knowledge about the quality criteria around MTMs and by overcoming practical barriers for the effective organization of MTMs.

RESUMO

PURPOSE: The aim of this study was to assess the management and the obstetrical and neonatal outcomes of pregnancies complicated by cancer. PATIENTS AND METHODS: In an international collaborative setting, patients with invasive cancer diagnosed during pregnancy between 1998 and 2008 were identified. Clinical data regarding the cancer diagnosis and treatment and the obstetric and neonatal outcomes were collected and analyzed. RESULTS: Of 215 patients, five (2.3%) had a pregnancy that ended in a spontaneous miscarriage and 30 (14.0%) pregnancies were interrupted. Treatment was initiated during pregnancy in 122 (56.7%) patients and postpartum in 58 (27.0%) patients. The most frequently encountered cancer types were breast cancer (46%), hematologic malignancies (18%), and dermatologic malignancies (10%). The mean gestational age at delivery was 36.3 +/- 2.9 weeks. Delivery was induced in 71.7% of pregnancies, and 54.2% of children were born preterm. In the group of patients prenatally exposed to cytotoxic treatment, the prevalence of preterm labor was increased (11.8%; P = .012). Furthermore, in this group a higher proportion of small-for-gestational-age children (birth weight below 10th percentile) was observed (24.2%; P = .001). Of all neonates, 51.2% were admitted to a neonatal intensive care unit, mainly (85.2%) because of prematurity. There was no increased incidence of congenital malformations. CONCLUSION: Pregnant cancer patients should be treated in a multidisciplinary setting with access to maternal and neonatal intensive care units. Prevention of iatrogenic prematurity appears to be an important part of the treatment strategy.

RESUMO

PURPOSE: To provide guidance for clinicians about the diagnosis, staging and treatment of breast cancer occurring during an otherwise uncomplicated pregnancy. METHODS: An international expert Panel convened to address a series of questions identified by a literature review and personal experience. Issues relating to the diagnosis and management of breast cancer after delivery were outside the scope. RESULTS: There is a paucity of large and/or randomized studies. Based on cohort studies, case series and case reports, the recommendations represent the best available evidence, albeit of a lower grade than is optimal. RECOMMENDATIONS: In most circumstances, serious consideration should be given to the option of treating breast cancer whilst continuing with the pregnancy. Each woman should ideally be referred to a centre with sufficient expertise, given a clear explanation of treatment options. Most diagnostic and staging examinations can be performed adequately and safely during pregnancy. Treatment should however be adapted to the clinical presentation and the trimester of the pregnancy: surgery can be performed during all trimesters of pregnancy; radiotherapy can be considered during the first and second trimester but should be postponed during the third trimester; and standard chemotherapies can be used during the second and third trimester. Since neonatal morbidity mainly appears to be related to prematurity, delivery should not be induced before 37 weeks, if at all possible. CONCLUSIONS: The treatment of breast cancer in pregnancy should be executed by experienced specialists in a multidisciplinary setting and should adhere as closely as possible to standard protocols.
