ABSTRACT
Female genital mutilation or cutting (FGM/C) is a practice involving the partial or complete removal of the external female genitalia for non-medical reasons. To facilitate attitude changes, the ecological model of behavior change considers multiple levels of influence and their relationships with environmental and behavioral factors. The combined effects of migration and cultural adaptation result in a transformative process that leads to decreased support for FGM/C. This qualitative study aimed to gain knowledge from FGM/C field professionals regarding the factors promoting behavioral changes in migrant communities in Geneva, Switzerland. Between September and October 2023, we conducted semi-structured interviews using a reflexive thematic analysis. Our qualitative research is reported in accordance with the COREQ criteria. A data analysis was performed using NVivo 14 software. Four influential dimensions were identified, each with associated factors. The first dimension, the social level, includes (1) the impact and implementation of anti-FGM/C laws. The second dimension, the community level, encompasses four factors such as (2) religion, (3) a multifaceted examination of social aspects, (4) navigating language barriers and raising awareness, and (5) cultural adaptation processes. The third dimension, the interpersonal level, includes factors such as (6) changing views on the marriage prerequisite. Finally, the fourth dimension, the personal level, is associated with (7) women's experiences and perspectives regarding FGM/C. The findings highlight seven environmental factors, both within and across dimensions of the ecological model, that interact with human behavior to enable an adaptive cultural process. This process influences changes in attitudes and behaviors regarding FGM/C.

A growing body of evidence indicates a significant decrease in support for female genital mutilation/cutting (FGM/C) within post-migration communities in Western countries. Addressing knowledge gaps and comprehending the factors associated with FGM/C discontinuation in these communities is crucial. The objective of this scoping review is to describe the effects of migration and cultural change on factors supporting FGM/C cessation in migrant communities. The review, from 2012 to 2023, included the following databases: Embase, PubMed, Google Scholar, Swisscovery, CINAHL, APA PsycInfo, and gray literature. Applying the PRISMA-ScR framework, we identified 2819 studies, with 17 meeting the inclusion criteria. The results revealed seven key factors shaping attitudes and behavior toward FGM/C abandonment: (1) legislation against FGM/C, (2) knowing that FGM/C is not a religious requirement, (3) enhancing education about the practice, (4) migration and cultural change, (5) awareness of the harmful effects of FGM/C, (6) a positive view of uncut girls, and (7) a sense of self-agency. These findings highlight factors on a social, community, interpersonal, and personal level that enhance the abandonment of the practice. Further research in the FGM/C field will gain more accuracy in understanding and accounting for these multilevel factors in post-migration settings, offering valuable insights for targeted interventions to promote the cessation of the practice.

The following study attempts to assess the link between the circumcision status of Ethiopian women and their ability to negotiate sex. From the 2016 Ethiopian Demographic and Health Survey, we analyzed a subsample of 3,445 women aged 15 to 49. Women's sexual negotiation ability was measured by their ability to ask for condom and their ability to refuse sex. We performed a univariate, bivariate, and multiple logistic regression analysis. In the final analysis, only education, residence, media access, and sexually transmitted infections knowledge were independently associated with the sexual negotiation ability of women. Circumcision status was not associated with sexual negotiation ability.
ABSTRACT
Female genital mutilation or cutting (FGMC) has profound consequences for an estimated 200 million women world-wide, yet affected communities often resist efforts to end the practice. Marriage market dynamics have been proposed as key to this resistance, because where FGMC is normative, parents are motivated to cut their daughters to improve their marriage prospects. Some economists have also argued that financial gain, through bride wealth payments, incentivises parents to cut daughter's at time of marriage. Bride wealth, however, does not necessarily equal net economic return, confounding efforts to test this assumption. Here we use detailed data on the financial value of all exchanges at marriage from Ethiopian Arsi Oromo agropastoralists to assess their association with FGMC. We also explore the idea that parents must replace FGMC with other forms of investment (e.g., education) when cutting practices are rejected. Multivariate multilevel Bayesian models were run using data from the first marriages of 358 women to assess the association between FGMC status and education and marriage-related outcomes: bride wealth payments, dowry costs, and age at marriage. Being cut is associated with lower dowry costs and earlier age at marriage but does not predict bride wealth paid by the groom's family. School attendance is associated with higher bride wealth, particularly for women with four or more years of education, and with later age at marriage. These findings indicate that bride wealth payments do not maintain FGMC among the Arsi Oromo. While we find a relative economic loss for parents from FGMC abandonment through higher value dowry gifts, this may be traded-off against the health benefits to uncut daughters. These findings point to the emergence of new norms, whereby Arsi Oromo parents reject cutting for their daughters and prefer their daughters-in-law to be educated.

Prostate cancer (PCa) is the second most frequent and sixth most fatal cancer in men worldwide. Despite its high prevalence, our understanding of its etiology and the molecular mechanisms involved in the progression of the disease is substantially limited. In recent years, the potential participation of exosomes in this process has been suggested. Therefore, we aim to study the effect of exosomes isolated from the serum of patients with PCa on various cellular processes associated with increased tumor aggressiveness in two PCa cell lines: LNCaP-FGC and PC3. The exosomes were isolated by filtration wand ultracentrifugation. Their presence was confirmed by immunodetection of specific markers and their size distribution was analyzed by Dynamic Light Scattering (DLS). The results obtained demonstrated that serum exosomes from PCa patients increased migration of PC3 cells and neuroendocrine differentiation of LNCaP-FGC cells regardless of the grade of the tumor. PCa serum exosomes also enhanced the secretion of enzymes related to invasiveness and resistance to chemotherapeutics, such as extracellular matrix metalloproteases 2 and 9, and gamma-glutamyltransferase in both cell lines. Altogether, these findings support the pivotal participation of exosomes released by tumoral cells in the progression of PCa. Future studies on the molecular mechanisms involved in the observed changes could provide crucial information on this disease and help in the discovery of new therapeutic targets.

Around 200 million women and girls worldwide are affected by female genital mutilation/cutting (FGM/C). FGM/C is a procedure that harms or alters the external female genitals for non-medical reasons, and is usually performed on children. Often, this procedure leads to severe consequences for the women's physical and mental health. In a cross-sectional sample of 112 women seeking medical counseling, physical and mental health characteristics associated with FGM/C were examined and possible predictors for the development of post-traumatic stress disorder (PTSD) in women affected by FGM/C were identified. A total of 55.4% (n = 66) of the women reported symptom levels of probable PTSD. Predictors for higher PTSD symptomology were an older age at the time of the FGM/C procedure, feelings of guilt and the centrality of the event in the woman's life. Thus, cognitive-emotional processing was found to play an important role in the emergence of PTSD in women suffering from FGM/C. However, interventions taking into consideration these characteristics are mostly lacking and need to be investigated further in the context of FGM/C.

Recently, we reported a new approach to develop pairwise analytical corrections to improve the description of noncovalent interactions, by approximate methods of electronic structures, such as semiempirical quantum mechanical (SQM) methods. In particular, and as a proof of concept, we used the PM6 Hamiltonian and we named the method PM6-FGC, where the FGC acronym, corresponding to Functional Group Corrections, emphasizes the idea that the corrections work for specific functional groups rather than for individual atom pairs. The analytical corrections were derived from fits to B3LYP-D3/def2-TZVP (reference). PM6 interaction energy differences, evaluated for a reduced set of small bimolecular complexes, were chosen as representatives of saturated hydrocarbons, carboxylic, amine and, tentatively, amide functional groups. For the validation, the method was applied to several complexes of well-known databases, as well as to complexes of diglycine and dialanine, assuming the transferability of amine group corrections to amide groups. The PM6-FGC method showed great potential but revealed significant inaccuracies for the description of some interactions involving the -NH2 group in amines and amides, caused by the inadequate selection of the model compound used to represent these functional groups (an NH3 molecule). In this work, methylamine and acetamide are used as representatives of amine and amide groups, respectively. This new selection leads to significant improvements in the calculation of noncovalent interactions in the validation set.
ABSTRACT
The health consequences of female genital mutilation (FGM) have been described previously; however, evidence of the social consequences is more intangible. To date, few systematic reviews have addressed the impact of the practice on psycho-social well-being, and there is limited understanding of what these consequences might consist. To complement knowledge on the known health consequences, this article systematically reviewed qualitative evidence of the psycho-social impact of FGM in countries where it is originally practiced (Africa, the Middle East, and Asia) and in countries of the diaspora. Twenty-three qualitative studies describing the psycho-social impact of FGM on women's lives were selected after screening. This review provides a framework for understanding the less visible ways in which women and girls with FGM experience adverse effects that may affect their sense of identity, their self-esteem, and well-being as well as their participation in society.

Female Genital Mutilation (FGM) is a harmful practice with no benefits and considerable harm to girls and women who undergo it. In 2016, the United Nations Joint Program to Eliminate FGM, funded the development and subsequent validation of a monitoring and evaluation framework to understand the relationship between social norms and practicing FGM. Evidence on the framework was gathered through a pilot study in Ethiopia. This paper uses cross-sectional quantitative data from the pilot to operationalize the framework and determine what factors are associated with practicing FGM. A total of 554 and 481 participants answered the question "Have you undergone FGM?" and "Do you know a family member who has undergone FGM?" respectively. Overall, 65% of participants said they had undergone FGM and 32% said they knew someone in their family who had undergone FGM. Predictors of not undergoing FGM included most progressive attitudes vs. less progressive attitudes about FGM and relationship to identity [OR: 1.9 (95% CI: 1.1-3.3)]; region [Afar vs. Addis Ababa: OR: 0.09 (95% CI: 0.02-0.5); Southern Nations Nationalities and People's Regions vs. Addis Ababa: OR: 0.1 (95% CI: 0.05-0.3)], being 36 years old and above vs. 10-19 years (OR: 0.2 (95% CI: 0.1 to 0.7)) and being single, never married vs. married or engaged (OR: 2.8 (95% CI: 1.1-7.0)]. Predictors of knowing a family member who has not undergone FGM included: Higher knowledge vs. lower knowledge [OR: 0.3 (95% CI: 0.1-0.5)]; if the family expected you to abandon FGM, you had a greater odds of knowing a family member who had not undergone FGM [43.6 (95% CI: 2.7-687.8)]; coming from Southern Nations, Nationalities and People's Region was associated with a lower odds of knowing a family member who had not undergone FGM [0.3 (95% CI: 0.1-0.6)]. Being a female influential vs. female caregiver was associated with a higher odds of knowing a family member who had not undergone FGM [2.9 (95% CI: 1.01-5.2)]. This paper has allowed us to validate a theory and research based social norms framework, specifically examining how social and behavior change communication can be used as a mechanism for shifting norms around a given harmful practice. Now that this model has been developed and validated, it is likely to provide a foundation to study the direct and indirect impacts of social norms programming on changing harmful practices, such as FGM.

BACKGROUND: Female genital mutilation (FGM) is a deeply-rooted cultural practice mainly undertaken in Africa, the Middle East and Asian countries. Evidence to date suggests that although first-generation migrants to the West are abandoning FGM, the custom continues in some places, albeit in small numbers. This study examined how young people living in FGM affected communities in the United Kingdom (UK), interpreted and explained FGM. METHODS: A community-based participatory research (CBPR) approach was used to recruit and train nine young people aged 15-18 as co-researchers. These comprised eight females and one male from second-generation FGM affected communities, living in Bristol. The co-researchers then undertook focus groups and semi-structured interviews with twenty participants aged 13-15 living in Bristol, Cardiff and Milton Keynes. The qualitative data from the training workshops, interviews and focus groups were collected and analysed using thematic analysis. RESULTS: There were conflicting views among participants. Some perceived FGM as a historical tradition that was of very little, if any, relevance to them. In contrast, others perceived that the more archaic, cultural interpretation of FGM, more commonly shared by older generations, had been supplanted by a new form of FGM, which they believed to be a safe procedure, made so by the availability of highly-trained, qualified doctors and better equipment in the UK. Participants spoke of challenges encountered when attempting to raise the issue of FGM with parents. Nevertheless, they acknowledged that- being born and raised in the UK - enabled them to talk openly and to challenge others. CONCLUSION: Future strategies to address and prevent FGM in the UK will require a public health approach that is holistic, intersectional and empowering. Such measures should be relevant to young people born and raised in the UK who interpret FGM differently to previous first-generation migrant relatives and communities. Tackling FGM requires a shift away from a principal preoccupation with harm reduction and criminalisation towards collaboration and active dialogue with communities, in positive and productive ways that acknowledge and engage issues of identity, race, gender, and generation, enabling people affected by FGM to take control of their health and well-being.

The present study examined the effectiveness of Family Group Conferencing (FGC) in child welfare. Effects were operationalized in terms of child safety (child maltreatment, supervision order, and out-of-home placement), number of professional services used, parental empowerment, and social support in a 1-, 3-, 6-, and 12-month follow-up. Furthermore, the influence of family characteristics and the level of FGC completion were examined. A total of 328 families were included, randomly assigned to an experimental group ( n = 229) and a care as usual (CAU) group ( n = 99). FGC was equally effective as CAU in improving child safety but resulted in more out-of-home placements. Furthermore, FGC resulted in a longer duration of child welfare involvement, a marginally higher number of professional services used, and increased parental empowerment and social support. Family characteristics did not moderate the results. Level of FGC completion was in general low. Higher levels of completion were related to a larger social network, a higher number of professional services used, and, marginally, less parental empowerment. In conclusion, although some beneficial results marginally support the use of FGC, it is the question whether these effects outweigh FGC costs, a longer duration of child welfare involvement and a higher number of professional services used.

Selenium deficiency is associated with many physiological disorders including the high risk of cancer. The rehabilitation of selenium with different selenium supplements, however, fails due to their low therapeutic index. Therefore, it is advantageous to have a less toxic form of selenium for supplementation with potentially high anticancer activity. Here we show Bacillus licheniformis derived biogenic selenium nanoparticles at a minimal concentration of 2 µg Se/ml induce necroptosis in LNCaP-FGC cells, without affecting the RBC integrity. Real-time gene expression analysis indicated the overexpression of tumor necrotic factor (TNF) and interferon regulatory factor (IRF1) and decreased expression of androgen receptor (AR) and prostate-specific antigen (PSA). Furthermore, histopathological analysis showed the subsequent oral administrations of 10 times higher concentration of these endotoxin free selenium nanoparticles in C3H/HeJ mice (50 mg Se/kg of body weight), induce significantly lower toxicity compared to the L-selenomethionine (5 mg Se/kg). Our study suggested that the biogenic SeNP could emerge as the safest form of selenium supplementation with potent anticancer activity.
ABSTRACT
Gastric cancer, a group of common malignancies, results in the most cancer mortality worldwide after only lung and colorectal cancer. Although familial gastric cancers have long been recognized, it was not until recently that they were discovered to be associated with mutations of specific genes. Mutations of CDH1, the gene encoding E-cadherin, are the most common germline mutations detected in gastric cancer and underlie hereditary diffuse gastric cancer (HDGC) syndrome. All reported HDGCs are the pure diffuse type by Lauren classification and are associated with dismal prognosis once the tumor invades the submucosa. Because CDH1 germline mutations are inherited in an autosomal-dominant fashion and have high penetrance, the International Gastric Cancer Linkage Consortium (IGCLC) developed criteria to facilitate the screening of CDH1 mutation carriers; these criteria have been proven to have excellent sensitivity and specificity. Recent histologic studies suggest that HDGC progresses through several stages. Even when the tumor becomes "invasive" in lamina propria, it may stay indolent for a long time. However, the molecular mechanisms that induce the transitions between stages and determine the length of the indolent phase remain to be determined. Although the standard management for CDH1 mutation carriers is prophylactic total gastrectomy, many questions must be answered before the surgery can be done. These include the optimal surveillance strategy, the best strategy to choose surgical candidates, and the ideal time to perform surgery. In addition to increasing the risk of gastric cancer, CDH1 germline mutations also increase the risk of invasive lobular carcinoma of the breast, and possibly colorectal adenocarcinoma, and are associated with blepharocheilodontic syndrome (a congenital development disorder). However, the optimal management of these conditions is less established owing to insufficient data regarding the risk of cancer development. This review focuses on molecular and histological findings in HDGC, as opposed to sporadic diffuse gastric cancer, and their implications for the management of CDH1 mutation carriers and the diagnosis and treatment of HDGC. Other conditions associated with CDH1 germline mutations and future research directions are also discussed.
ABSTRACT
BACKGROUND: Female Genital Cutting (FGC) is a harmful traditional practice that affects the physical and mental health of girls and women in many ways. In Ethiopia, although both governmental institutions and None-Governmental- Institutions (NGOs) launched different campaigns against FGC, their effects on the peoples' attitudes towards the practice have not been deeply investigated yet. Hence, this study particularly aimed to investigate the pupils' perspectives on FGC abandonment in the Harari and the Somali Regional States of Ethiopia where the prevalence of the practice was thought to be high. METHODS: A school-based cross-sectional study was conducted in the Somali and the Harari Regional States of eastern Ethiopia from October to December 2015. While purposive sampling was implemented to select the study areas from the two Regional States, stratified random sampling method was used to select 480 study subjects from those areas. RESULTS: The findings showed that the participants who received information through multiple information channels were more likely to support the abandonment of FGC than those who received information from a single source (p < 0.05). Similarly, the findings indicated that school-based awareness campaigns and TV-based media communications were the main sources of information that influenced a high proportion of young people to support the abandonment of the practice. The findings revealed that the majority of the participants strongly supported the abandonment of FGC. CONCLUSIONS: Multiple information channels that include school-based awareness campaigns were found to be the best way to support the abandonment of FGC. Although the study shows an impressive improvement among the school girls and boys in recognizing the harmful effects FGC, complete abandonment of the practice might not be easily achieved due to its deep-rooted nature. Thus, to quicken the perpetuation of FGC in the stated Regional States, awareness creating campaigns that change the attitudes of youths towards the practice should be delivered through various sources. In this regard, school-based education, school mini-media, social media, and using the co-curricular activities to uncover the danger of this harmful practice could play significant roles in changing the pupils' attitudes towards the practice.

Critics of non-therapeutic male and female childhood genital cutting claim that such cutting is harmful. It is therefore puzzling that 'circumcised' women and men do not typically regard themselves as having been harmed by the cutting, notwithstanding the loss of sensitive, prima facie valuable tissue. For female genital cutting (FGC), a commonly proposed solution to this puzzle is that women who had part(s) of their vulvae removed before sexual debut 'do not know what they are missing' and may 'justify' their genitally-altered state by adopting false beliefs about the benefits of FGC, while simultaneously stigmatising unmodified genitalia as unattractive or unclean. Might a similar phenomenon apply to neonatally circumcised men? In this survey of 999 US American men, greater endorsement of false beliefs concerning circumcision and penile anatomy predicted greater satisfaction with being circumcised, while among genitally intact men, the opposite trend occurred: greater endorsement of false beliefs predicted less satisfaction with being genitally intact. These findings provide tentative support for the hypothesis that the lack-of-harm reported by many circumcised men, like the lack-of-harm reported by their female counterparts in societies that practice FGC, may be related to holding inaccurate beliefs concerning unaltered genitalia and the consequences of childhood genital modification.

BACKGROUND: Traumatic neuromas are the result of regenerative disorganized proliferation of the proximal portion of lesioned nerves. They can exist in any anatomical site and are responsible for neuropathic pain. Post-traumatic neuromas of the clitoris have been described as an uncommon consequence of female genital mutilation/cutting (FGM/C). FGM/C involves partial or total removal of the female genital organs for non-therapeutic reasons. It can involve cutting of the clitoris and can cause psychological, sexual, and physical complications. We aimed to evaluate the symptoms and management of women presenting with a clitoral neuroma after female genital mutilation/cutting (FGM/C). METHODS: We identified women who attended our specialized clinic for women with FGM/C who were diagnosed with a traumatic neuroma of the clitoris between April 1, 2010 and June 30, 2016. We reviewed their medical files and collected socio-demographic, clinical, surgical, and histopathological information. RESULTS: Seven women were diagnosed with clitoral neuroma. Six attended our clinic to undergo clitoral reconstruction, and three of these suffered from clitoral pain. The peri-clitoral fibrosis was removed during clitoral reconstruction, which revealed neuroma of the clitoris in all six subjects. Pain was ameliorated after surgery. The seventh woman presented with a visible and palpable painful clitoral mass diagnosed as a neuroma. Excision of the mass ameliorated the pain. Sexual function improved in five women. One was not sexually active, and one had not yet resumed sex. CONCLUSION: Post-traumatic clitoral neuroma can be a consequence of FGM/C. It can cause clitoral pain or be asymptomatic. In the case of pain symptoms, effective treatment is neuroma surgical excision, which can be performed during clitoral reconstruction. Surgery should be considered as part of multidisciplinary care. The efficacy of neuroma excision alone or during clitoral reconstruction to treat clitoral pain should be further assessed among symptomatic women.

At present, the geographical origin of extra virgin olive oils can be ensured by documented traceability, although chemical analysis may add information that is useful for possible confirmation. This preliminary study investigated the effectiveness of flash gas chromatography electronic nose and multivariate data analysis to perform rapid screening of commercial extra virgin olive oils characterized by a different geographical origin declared in the label. A comparison with solid phase micro extraction coupled to gas chromatography mass spectrometry was also performed. The new method is suitable to verify the geographic origin of extra virgin olive oils based on principal components analysis and discriminant analysis applied to the volatile profile of the headspace as a fingerprint. The selected variables were suitable in discriminating between "100% Italian" and "non-100% Italian" oils. Partial least squares discriminant analysis also allowed prediction of the degree of membership of unknown samples to the classes examined.

Functionally graded materials (FGMs) are innovative materials whose composition and/or microstructure gradually vary in space according to a designed law. As a result, also the properties gradually vary in space, so as to meet specific non-homogeneous service requirements without any abrupt interface at the macroscale. FGMs are emerging materials for orthopedic prostheses, since the functional gradient can be adapted to reproduce the local properties of the original bone, which helps to minimize the stress shielding effect and, at the same time, to reduce the shear stress between the implant and the surrounding bone tissue, two critical prerequisites for a longer lifespan of the graft. After a brief introduction to the origin of the FGM concept, the review surveys some representative examples of graded systems which are present in nature and, in particular, in the human body, with a focus on bone tissue. Then the rationale for using FGMs in orthopedic devices is discussed more in detail, taking into account both biological and biomechanical requirements. The core of the paper is dedicated to two fundamental topics, which are essential to benefit from the use of FGMs for orthopedic applications, namely (1) the computational tools for materials design and geometry optimization, and (2) the manufacturing techniques currently available to produce FGM-based grafts. This second part, in its turn, is structured to consider the production of functionally graded coatings (FGCs), of functionally graded 3D parts, and of special devices with a gradient in porosity (functionally graded scaffolds). The inspection of the literature on the argument clearly shows that the integration of design and manufacturing remains a critical step to overpass in order to achieve effective FGM-based implants.

INTRODUCTION: Clitoral reconstruction following female genital mutilation/cutting (FGM/C) is a new surgical technique reported to be a feasible and effective strategy to reduce clitoral pain, improve sexual pleasure, and restore a vulvar appearance similar to uncircumcised women. However, data on safety, care offered, and evaluation of sexual and pain outcomes are still limited. AIMS: This study aims to present the care offered and clinical outcomes of two women who received multidisciplinary care, including psychosexual treatment, with clitoral reconstruction. We report their long-term outcomes, and the histology of the removed periclitoral fibrosis. METHODS: We report the cases of two women with FGM/C types II and III who requested clitoral reconstruction for different reasons. One woman hoped to improve her chronic vulvar pain, as well as improve her sexual response. The other woman requested surgery due to a desire to reverse a procedure that was performed without her consent, and a wish to have a genital appearance similar to non infibulated women. They both underwent psychosexual evaluation and therapy and surgery. The histology of the periclitoral fibrosis removed during surgery was analyzed. RESULTS: At 1-year postoperatively, the first woman reported complete disappearance of vulvar pain and improved sexual pleasure, including orgasm. Our second patient also described improved sexuality at 1-year follow-up (increased sexual desire, lubrication, vulvar pleasure, and sensitiveness), which she attributed to a better self body image and confidence. Both women reported feeling satisfied, happy, and more beautiful. CONCLUSION: We show a positive outcome in pain reduction and improved sexual function, self body image, and gender after psychosexual therapy and clitoral reconstruction. More evidence is needed about clitoral reconstruction to develop guidelines on best practices. Until research is conducted that rigorously evaluates clitoral reconstruction for its impact on pain and sexuality, we advise always offering a multidisciplinary care, including sexual therapy before and after the surgery.

Familial gigantiform cementoma is a rare benign fibrocemento-osseous lesion of the jaws that can cause severe facial deformity. It has an autosomal dominant mode of inheritance, but varies in its phenotype. It is more common in white, African, and East-Asian patients. Here we report what is to our knowledge the first distinctive Chinese family with familial gigantiform cementoma involving 4 generations and 13 patients, and which suggests that the tumour presents with 3 distinctive growth phrases.
