ABSTRACT

PURPOSE: As a secondary report to elucidate the diverse spectrum of oncofertility practices for childhood cancer around the globe, we present and discuss the comparisons of oncofertility practices for childhood cancer in limited versus optimum resource settings based on data collected in the Repro-Can-OPEN Study Part I & II. METHODS: We surveyed 39 oncofertility centers including 14 in limited resource settings from Africa, Asia, and Latin America (Repro-Can-OPEN Study Part I), and 25 in optimum resource settings from the USA, Europe, Australia, and Japan (Repro-Can-OPEN Study Part II). Survey questions covered the availability of fertility preservation and restoration options offered in case of childhood cancer as well as their degree of utilization. RESULTS: In the Repro-Can-OPEN Study Part I & II, responses for childhood cancer and calculated oncofertility scores showed the following characteristics: (1) higher oncofertility scores in optimum resource settings than in limited resource settings for ovarian and testicular tissue cryopreservation; (2) frequent utilization of gonadal shielding, fractionation of anticancer therapy, oophoropexy, and GnRH analogs; (3) promising utilization of oocyte in vitro maturation (IVM); and (4) rare utilization of neoadjuvant cytoprotective pharmacotherapy, artificial ovary, in vitro spermatogenesis, and stem cells reproductive technology as they are still in preclinical or early clinical research settings. CONCLUSIONS: Based on Repro-Can-OPEN Study Part I & II, we presented a plausible oncofertility best practice model to help optimize care for children with cancer in various resource settings. Special ethical concerns should be considered when offering advanced and innovative oncofertility options to children.

ABSTRACT

PURPOSE: As a further step to elucidate the actual diverse spectrum of oncofertility practices for breast cancer around the globe, we present and discuss the comparisons of oncofertility practices for breast cancer in limited versus optimum resource settings based on data collected in the Repro-Can-OPEN Study Part I & II. METHODS: We surveyed 39 oncofertility centers including 14 in limited resource settings from Africa, Asia & Latin America (Repro-Can-OPEN Study Part I), and 25 in optimum resource settings from the United States, Europe, Australia and Japan (Repro-Can-OPEN Study Part II). Survey questions covered the availability of fertility preservation and restoration options offered to young female patients with breast cancer as well as the degree of utilization. RESULTS: In the Repro-Can-OPEN Study Part I & II, responses for breast cancer and calculated oncofertility scores showed the following characteristics: (1) higher oncofertility scores in optimum resource settings than in limited resource settings especially for established options, (2) frequent utilization of egg freezing, embryo freezing, ovarian tissue freezing, GnRH analogs, and fractionation of chemo- and radiotherapy, (3) promising utilization of oocyte in vitro maturation (IVM), (4) rare utilization of neoadjuvant cytoprotective pharmacotherapy, artificial ovary, and stem cells reproductive technology as they are still in preclinical or early clinical research settings, (5) recognition that technical and ethical concerns should be considered when offering advanced and innovative oncofertility options. CONCLUSIONS: We presented a plausible oncofertility best practice model to guide oncofertility teams in optimizing care for breast cancer patients in various resource settings.

ABSTRACT

PURPOSE: Impaired fertility in cancer patients and survivors of reproductive age (15-45 years) may lead to psychological distress and poor mental health outcomes, and may negatively impact quality of life. Limited research has focused on the fertility experiences of those who have had access to supportive oncofertility care. This study aims to explore the fertility-care experiences and reproductive concerns of reproductive age cancer patients at the time of their cancer diagnosis who have had access to oncofertility care. METHODS: The qualitative data from a larger mixed method study is presented, comprising 30 semi-structured telephone interviews with newly diagnosed cancer patients across Australia and New Zealand, undertaken between April 2016 and April 2018. RESULTS: Interviews were undertaken with 9 male patients and 21 female patients aged between 15 and 44 years. All patients recalled a discussion about fertility and majority underwent some form of fertility preservation. Thematic analysis identified five main themes: (i) satisfaction with oncofertility care, (ii) a need for individualised treatment and support, (iii) desire for parenthood, (iv) fertility treatment can be challenging, and (v) fertility preservation provides a safety net for the future. CONCLUSIONS: Participants who access supportive oncofertility care report low emotional impact of threatened future infertility at the time of cancer diagnosis. These results suggest that such services may assist in lowering the emotional burden of potential infertility in survivors. Long-term research is needed to assess the longitudinal benefits for different models of care.

ABSTRACT

BACKGROUND/PURPOSE: To describe the clinicopathological characteristics and management of surgically removed ovarian masses at the Royal Children's Hospital, Melbourne from 1993 to 2012. METHODS: Medical records were reviewed retrospectively. Data regarding clinical findings, imaging and surgical management were evaluated. RESULTS: There were 266 ovarian masses found in 258 surgeries (eight had bilateral masses). Most were benign (246/266, 92.5%), 2.3% (6/266) were borderline, and 5.3% (14/266) were malignant. The most common presenting symptom was abdominal pain for benign masses (169/246, 68.7%), and a palpable mass for borderline and malignant masses (12/20, 60.0%). Sensitivity and specificity of ultrasound for detection of malignancy was 64.7% and 52.9% respectively. Ovarian torsion occurred in 22.1% (n=57), none with malignancy, with seven cases diagnosed under one year of age. Sensitivity and specificity of ultrasound for ovarian torsion was 22.0% and 91.9%, respectively. The proportion undergoing ovarian cystectomy rather than oophorectomy has increased from 56.3% during 1993-1997 to 93.8% during 2008-2012 (p<0.005). Ovarian torsion was managed with ovarian conservation in 82.6% of cases between 2008-2012. CONCLUSION: The majority of pediatric and adolescent ovarian masses were benign. Sensitivity of ultrasound was fair for detection of malignancy, and poor for ovarian torsion. Conservative surgeries are increasingly common. LEVEL OF EVIDENCE: Level IV - case series with no comparison group TYPE OF STUDY: Retrospective Study.

ABSTRACT

Anorexia nervosa (AN) initiates an adaptive response at the level of the hypothalamus, which results in a complex interplay involving most elements of the neuroendocrine axis. Consequences of onset of disease in adolescence include amenorrhoea, pubertal arrest with potential loss of target height, and osteoporosis with reduced capacity for future attainment of peak bone mass. With recovery, delay in restoration of menses is common. Hormonal therapies for restoration of bone mineral density (BMD) in adolescents have shown limited efficacy. This review will discuss the reproductive endocrine effects of AN in adolescence, and discuss new investigative tools for monitoring restoration of reproductive function and BMD in this population.

ABSTRACT

Human papillomaviruses (HPVs) are a diverse family of viruses, of which 30-40 genotypes specifically infect the genital tract. Genital HPVs are largely transmitted sexually, with most infections being asymptomatic and transient. In contrast, persistent infection with oncogenic genotypes in a minority is a strong risk factor, for subsequent development of high grade dysplasia, the precursor lesion to cervical neoplasia, which generally occurs after a long latency period. It is unknown whether there is a disease correlate in children chronically infected with oncogenic HPVs. Low risk HPV genotypes 6 and 11 are the primary cause of condylomata acuminata, although in children non-genital genotypes are also found in a proportion, with the mode of transmission being either perinatal, horizontal, or sexual. The finding of asymptomatic HPV DNA in children, and correlation with live virus, infectivity, or disease is unclear. Long term follow up for children with anogenital warts is recommended, although there are no longitudinal studies available to clarify whether they are at risk of developing carcinoma in young adulthood.
