RESUMO

Background: One in eight women will be diagnosed with breast cancer. At the time of diagnosis, 75% of patients are postmenopausal. Many will receive anti-hormone therapy, which often induces menopausal symptoms. Premenopausal breast cancer patients frequently become postmenopausal as a result of the treatment and often experience menopausal symptoms. The increased incidence of breast cancer, combined with longer survival, has led to an increase in the number of women experiencing menopausal symptoms. Therefore, the management of menopausal symptoms in women with a history or current breast cancer is a relevant and common clinical problem. Objectives: To provide a clinically useful overview of the steps in the management of menopausal symptoms in women with (a history of) breast cancer. Materials and Methods: A comprehensive literature review was conducted by authors JS and WT using the PubMed and Medline databases. Abstracts were critically appraised and, where appropriate, the full text was analysed. Main Outcome Measures: Not applicable. Results: Depending on the condition, either meta-analyses, randomised controlled trials or retrospective cohorts were identified. No evidence was found for some proposed treatments. Conclusions: Menopausal symptoms in women with (a history of) breast cancer require a patient-tailored approach. Shared decision making is paramount and adequate up-to-date knowledge can help the breast cancer specialist to advise and guide patients accordingly. What is new?: A comprehensive, clinically-based overview of evidence-based treatment options for menopausal symptoms in women with (a history of) breast cancer.

RESUMO

Background: The VVOG (Flemish Society of Obstetrics and Gynaecology) published a consensus statement promoting opportunistic bilateral salpingectomy (OBS). Objectives: The aim of the study was to obtain insight into the current opinion and general practice of Flemish gynaecologists to counsel and perform OBS. Materials and Methods: A questionnaire was distributed to Flemish gynaecologists three months following publication. Main outcome measures: The drawbacks and incentives to counsel and perform OBS were questioned. Results: Complete response rate was obtained from 99 gynaecologists (17%) and 37 trainees (19%). The majority of respondents (77%) always counselled for OBS in patients scheduled for hysterectomy without oophorectomy. Eighteen per cent counselled only above a certain age cut off and/or if patient was already menopausal. The most important incentive to counsel in cases of hysterectomy by the abdominal approach and vaginal hysterectomy (VH) was the opportunity to prevent ovarian cancer. The yet-undetermined risk of premature ovarian failure was mentioned as the most important barrier in counselling women for OBS in those undergoing hysterectomy by the abdominal approach. For VH, the respondents saw the risk of complications and increased surgical time as the most important barriers. Sixty-one percent of gynaecologists preferred to perform bilateral salpingectomy as sterilisation method. Conclusions: Our study suggests that the concept of OBS is already well known in Flanders. There is a positive attitude towards the routine implementation of OBS, although some barriers and doubts about an age cut-off still exist in practice.

RESUMO

INTRODUCTION: Inflammatory breast cancer (IBC) is an uncommon, but aggressive form of breast cancer that accounts for a disproportionally high fraction of breast cancer related mortality. The aim of this study was to explore the peripheral immune response and the prognostic value of blood-based biomarkers, such as the neutrophil-to-lymphocyte ratio (NLR), in a large IBC cohort. PATIENTS & METHODS: We retrospectively identified 127 IBC patients and collected lab results from in-hospital medical records. The differential count of leukocytes was determined at the moment of diagnosis, before any therapeutic intervention. A cohort of early stage (n = 108), locally advanced (n = 74) and metastatic breast cancer patients (n = 41) served as a control population. RESULTS: The NLR was significantly higher in IBC compared to an early stage breast cancer cohort, but no difference between IBC patients and locally advanced breast cancer patients was noted. In the metastatic setting, there was also no significant difference between IBC and nIBC. However, a high NLR (>4.0) remained a significant predictor of worse outcome in IBC patients (HR: 0.49; 95% CI: 0.24-1.00; P = .05) and a lower platelet-lymphocyte ratio (PLR) (≤210) correlated with a better disease-free survival (DFS) (HR: 0.51; 95% CI: 0.28-0.93; P = .03). CONCLUSION: Patients with a high NLR (>4.0) have a worse overall prognosis in IBC, while the PLR correlated with relapse free survival (RFS). Since NLR and PLR were not specifically associated with IBC disease, they can be seen as markers of more extensive disease.

RESUMO

BACKGROUND: Inflammatory breast cancer (IBC) is a rare and rapidly progressive form of invasive breast cancer. The aim of this study was to explore the clinical evolution, stromal tumour-infiltrating lymphocytes (sTIL) infiltration and programmed death-ligand 1 (PD-L1) expression in a large IBC cohort. PATIENTS AND METHODS: Data were collected prospectively from patients with IBC as part of an international collaborative effort since 1996. In total, 143 patients with IBC starting treatment between June 1996 and December 2016 were included. Clinicopathological variables were collected, and sTIL were scored by two pathologists on standard H&E stained sections. PD-L1 expression was assessed using a validated PD-L1 (SP142) assay. A validation cohort of 64 patients with IBC was used to test our findings. RESULTS: Survival outcomes of IBC remained poor with a 5-year overall survival (OS) of 45.6%. OS was significantly better in patients with primary non-metastatic disease who received taxane-containing (neo)adjuvant therapy (P = 0.01), had a hormone receptor-positive tumour (P = 0.001) and had lower cN stage at diagnosis (P = 0.001). PD-L1 positivity on immune cells (42.9%) was higher in IBC than in non-IBC in both our patient samples and the validation cohort. Furthermore, PD-L1 expression predicted pCR (P = 0.002) and correlated with sTIL infiltration (P < 0.001). sTIL infiltration of more than 10% of the stroma was a significant predictor of improved OS (HR 0.47, 95% CI 0.27-0.81, P = 0.006) in a multivariate model. CONCLUSIONS: IBC is characterised by poor survival and high PD-L1 immunoreactivity on sTIL. This suggests a role for PD1/PD-L1 inhibitors in the treatment of IBC. Furthermore, we showed that PD-L1 expression predicts response to neo-adjuvant therapy and that sTIL have prognostic significance in IBC.

RESUMO

AIM: The objective of present study was to investigate whether conisation is associated with adverse pregnancy outcomes in Flanders, Belgium. Therefore a retrospective cohort study was conducted at the Antwerp University Hospital. MATERIALS AND METHODS: The study was approved by the Ethical Committee and based on a questionnaire as well as on medical records. Confounders, like smoking, alcohol use, drug use, chronic illness, and gynaecological disorders during pregnancy were all taken into account. A multiple logistic regression was performed for an association between adverse pregnancy outcomes and confounders. RESULTS: The study showed that there was association between conisation, low birth weight, and caesarean section. After conisation there was a significantly higher risk of 3.275 on a low birth weight. The risk of a caesarean section after conisation was tripled. A gynaecological disorder during the pregnancy had a significantly higher risk of delivering a child with a low birth weight and a higher risk of a caesarean section. Smoking and a chronic illness gave a significant higher risk of caesarean section. DISCUSSION: Conisation is easy to perform and highly effective in the prevention of cervical cancer. Conisation has a high morbidity, as it is associated with severe adverse pregnancy outcome. A conisation should therefore only be performed on a true indication; otherwise it will be the victim of its own success.

RESUMO

CASE: A 58-year old woman presented with microcalcifications in her left breast. A biopsy showed a low-grade ductal carcinoma in situ. A tumorectomy was performed using a harpoon-shaped guide wire to remove the entire lesion. No additional therapy was given. Six months later during follow-up the mammography revealed that the distal end of the guide wire was still present in the left breast. CONCLUSION: When performing a tumorectomy using a guide wire, the completeness of the wire should be checked during surgery. Additionally cutting of the wire can be prevented by using a scalpel instead of scissors during surgery.

RESUMO

OBJECTIVE: Despite an advanced national cervical cancer screening and vaccination programme cervical cancer is still the third most frequent diagnosed gynaecological tumour in Belgium. The goal of this study is to present the Belgian data of a cross-sectional, multicentre, epidemiological study on human papillomavirus (HPV) type distribution in adult women diagnosed with invasive cervical cancer (ICC) conducted in 12 European countries. MATERIAL AND METHODS: Centres in four major Belgian cities (Antwerp, Brussels, Ghent and Liège) participated in this study. Tissue samples from women with ICC were collected from the period 2001 - 2008. All slides were centrally reviewed and analysed for HPV. The total enrolled cohort included 278 subjects. RESULTS: The histologically eligible cohort comprised of 255 patients (mean age 51.3 ± 15.1 years) and 237 were confirmed HPV positive (mean age 50.6 ± 14.9 years). A single HPV infection was present in 95.8%. The five most frequent HPV types were HPV 16 (68.7%), HPV18 (12.3%), HPV 31 (6.2%), HPV 33 (5.3%) and HPV 45 (1.8%). Multiple HPV types were present in 3.4%, with two HPV types in 2.5% and three HPV types in 0.8%. In the various HPV type combinations observed in multiple infected women, HPV 31 (62.5%) and HPV 33 (50.0%) were the most frequent. The ratio of adenocarcinoma (ADC) versus squamous cell carcinoma (SCC) cases in the histologically eligible cohort was 1:8. Compared to the pooled European data the Belgium HPV 16 is 1.1, HPV 33 is 1.2 and HPV 31 is 1.7 higher and the HPV 18 is 0.8 and HPV 45 is 0.34 lower. CONCLUSION: The 5 most frequent HPV types in Belgium are the same as in the rest of Europe, but the distribution is different. Cervical cancer screening should therefore be HPV type specific and HPV prophylactic vaccination should also focus on other types then HPV 16 and HPV 18. A national registry is needed in order to follow the trends of HPV types in the society and to measure the impact of prevention, for which the data presented in this study can be an important basis.

RESUMO

Trastuzumab was the first targeted therapy for HER2 positive breast cancer. It has become the standard of care for HER2 positive metastatic breast cancer since 2000 and in the adjuvant setting since 2006. Adjuvant it is given for a year and in patients with metastatic disease until progression. The standard mode of administration is intravenous. Recently a subcutaneous form has become available. A phase III study showed that there is no difference between the intravenous and subcutaneous form in terms of safety and efficacy. The patient's preference however significantly favoured the subcutaneous form. It is estimated that the use of the SC form could contribute to a cost saving between 758 and 2576 euro per annual course. For Belgium alone this could mean an estimated saving of 1.4 to 4.6 million euros per year. The potential benefit of the SC administration for healthcare facilities could be further increased when applied in a LEAN working day-care chemotherapy unit. After reviewing the existing literature we suggest to further validate the potential financial impact of SC trastuzumab compared to the traditional IV form and to introduce a scientific proposal incorporating the benefits of this formulation in a LEAN working healthcare unit.

RESUMO

The hormone dependent breast and prostate cancers have in general a very good survival, due to the anti-hormonal treatment. A disadvantage of this treatment is the increased risk of osteoporosis and fractures. It is surprisingly to note that denosumab has the same impact on fracture reduction incidence for both sexes, but with different reimbursement criteria. Furthermore there is only reimbursement in case of osteoporosis and not for cancer patients who are at an increased risk of developing osteoporosis. The clinician detects the accelerated bone loss during follow-up, but has to wait until there is osteoporosis. The impact of osteoporosis on the quality of life is severe and underestimated. Management of cancer should not only focus on survival, therefore it is time to reconsider the reimbursement criteria, discuss the willingness of society to pay for bone health and make choices regarding the advice we give to our patients.

RESUMO

Almost 1% of all cervical cancers occur in pregnant women. The recommended management during the first 20 weeks is to sacrifice the pregnancy and to perform standard therapy, which means the loss of future fertility. A trachelectomy during pregnancy could preserve the ongoing pregnancy and future fertility. The author reports a radical vaginal trachelectomy (RVT) during 18 weeks of pregnancy. Definitive pathology of the trachelectomy specimen showed a tumor of 48 millimeters. Subsequently a radical hysterectomy was performed. At present, eight years and six months later the patient is well with no signs of recurrence. RVT is feasible in the first and second trimester of pregnancy. Clinical examination and MRI however are less accurate in the evaluation of stage and the extent of the tumor during pregnancy. Converting a RVT to a radical hysterectomy in a second time is safe in a pregnant woman.

RESUMO

Evaluating and "cleaning" of the uterine cavity is probably the most performed operation in women. It is done for several reasons: abortion, evaluation of irregular bleeding in premenopausal period, and postmenopausal bleeding. Abortion is undoubtedly the number one procedure with more than 44 million pregnancies terminated every year. This procedure should not be underestimated and a careful preoperative evaluation is needed. Ideally a sensitive pregnancy test should be done together with an ultrasound in order to confirm a uterine pregnancy, excluding extra-uterine pregnancy, and to detect genital and/or uterine malformations. Three out of four abortions are performed by surgical methods. Surgical methods include a sharp, blunt, and suction curettage. Suction curettage or vacuum aspiration is the preferred method. Despite the fact that it is a relative safe procedure with major complications in less than one percent of cases, it is still responsible for 13% of all maternal deaths. All the figures have not declined in the last decade. Trauma, perforation, and bleeding are a danger triage. When there is a perforation, a laparoscopy should be performed immediately, in order to detect intra-abdominal lacerations and bleeding. The bleeding should be stopped as soon as possible in order to not destabilize the patient. When there is a perforation in the uterus, this "entrance" can be used to perform the curettage. This is particularly useful if there is trauma of the isthmus and uterine wall, and it is difficult to identify the uterine canal. A curettage is a frequent performed procedure, which should not be underestimated. If there is a perforation in the uterus, then this opening can safely be used for vacuum aspiration.

RESUMO

Cervical cancer should be a historical disease, why are we not succeeding! The prophylactic vaccination will reduce cervical cancer by almost 80% in Belgium. Cervical cancer screening should therefore remain in order to prevent the remaining 20%. The current used Pap cytology test misses 50% of all clinically significant precancers and cancers at the time of testing. The test should remain but the analysis should be altered. The screening should be modified based on our knowledge of human papillomavirus (HPV) as causal factor. Instead of looking for a cell abnormality, one should look for the presence of HPV. Then depending on the test, only two to ten percent of all relevant lesions are missed. The introduction of the vaccination should lead to the re-introduction of the screening based on HPV. This will not only lead to a considerable reduction in morbidity and mortality, allow longer screening intervals, but it will also be more cost-effective. More for less should be the driving force in cervical cancer screening if we want to be successful.

RESUMO

Although the aetiology of urinary incontinence can be multifactorial, in some cases weight loss could be considered as a part of the therapeutic approach for urinary incontinence in people who are overweight. The objective of this study was to review and meta-analyse the effect of non-surgical weight loss interventions on urinary incontinence in overweight women. Web of Science, PubMed, Pedro, SPORTDiscus and Cochrane were systematically searched for clinical trials that met the a priori set criteria. Data of women who participated in non-surgical weight loss interventions (diet, exercise, medication or a combination) were included in the meta-analysis. After removing duplicates, 62 articles remained for screening on title, abstract and full text. Six articles (totalling 2,352 subjects in the intervention groups) were included for meta-analysis. The mean change in urinary incontinence (reported as frequency or quantity, depending on the study) after a non-surgical weight loss intervention, expressed as standardized effect size and corrected for small sample sizes (Hedges' g), was -0.30 (95%CI = -0.47 to -0.12). This systematic review and meta-analysis shows evidence that a non-surgical weight loss intervention has the potential to improve urinary incontinence and should be considered part of standard practice in the management of urinary incontinence in overweight women.

RESUMO

BACKGROUND: Due to cervical cancer screening the number of squamous cancer have declined. The number of adenocarcinomas (ADCs) does appear to be rising. ADCs are often missed and human papillomavirus (HPV) testing could be helpful in detecting these abnormalities earlier. CASE: A 36-year-old woman, who had a normal smear three years earlier, had a pap smear with atypical glandular cells. The L1 HPV test showed that there was no HPV infection. Other HPV tests which looked at E6 and E7 showed an infection with HPV 16. Due to unknown reasons, no action was taken regarding the atypical glandular cells. Two years later the patient was diagnosed with a FIGO Stage IVb ADC of the cervix. The L1 HPV test was still negative and the E6/E7 HPV test was still positive. Despite several multiple treatment modalities she succumbed of her disease two years later leaving behind a young family. CONCLUSION: HPV test looking only at L1 can give false negative results if the virus is integrated in the human genome.

RESUMO

AIM: The lifetime risk for acquiring a human papilloma virus (HPV) infection is 80% for sexually active people. High-risk HPVs are causally related to almost every case of cervical cancer, and to a subgroup of vaginal, vulvar, anal, penile and oral/oropharyngeal cancer. Low-risk HPVs are related to cutaneous, anogenital, and oral warts. Two prophylactic vaccines were launched in 2007: they were included in the national vaccination program in Belgium (2009) and in the Netherlands (2010). The objectives of the present study were to determine and compare knowledge and attitudes regarding HPV and vaccination among a study population in 2006 and in 2012. MATERIALS AND METHODS: Shortly before the introduction, and three years after the inclusion, 715 (2006) and 678 participants (2012) were questioned. Participants were categorised as into non-medics, medics, or paramedics. RESULTS: In general, knowledge about HPV has increased over time (p<0.01). Well-known facts are the relationship of HPV with cervical cancer (>94% in 2006; >96% in 2012), and that an HPV infection might be asymptomatic (>95% in 2006; >99% in 2012). In 2012, versus in 2006, paramedics and non-medics (both p<0.01), were more likely to vaccinate all female teenagers. Medics were less likely to support this (p=0.001). More respondents agreed to vaccinate their daughters (p<0.01), as well as their sons (p<0.01). In 2012, when compared with 2006, less non-medics and medics (both p<0.01) and more paramedics (p=0.001) would accept a free catch-up vaccination. Arguments against catch-up vaccination reflected the belief not being at risk and doubts about the vaccines' safety. CONCLUSION: The facts that vaccination programs are regarded as being important, and that knowledge on HPV increased, do not automatically result in an increase in participation in HPV vaccination programs. To increase participation, information must be provided with arguments that cannot be misinterpreted.

RESUMO

Cervical cancer can and should be a historical disease. The reality, however, is that every year more than half a million women are diagnosed with cervical cancer and a quarter of a million die of this disease. The causal factor for cervical cancer is a persistent HPV infection and therefore a vaccine was developed: prophylactic HPV vaccination will reduce cervical cancer by 70%. Screening based on cytology will miss more than 40% of the abnormalities. The introduction of vaccination should lead to the reintroduction of cervical cancer screening based on HPV detection. Primary HPV screening followed by cytology will detect almost all abnormalities. Not all HPV tests, however, are the same! Clinicians are generally not aware that there is a huge difference among HPV tests. If a low grade lesion progresses to a high grade or invasive cancer, their HPV is likely to integrate. During integration L1 expression can be lost, but E6/E7 expression will always remain present. If the viral HPV is completely integrated then a L1 test looking for only L1 expression will miss this (pre)cancer, while the E6/E7 test will not miss it. HPV tests used in cervical cancer screening should be based on the early (E) and the late (L) genes in order not to miss the abnormality.
