Management of fertility in patients treated for Hodgkin's lymphoma

Recurrent spontaneous miscarriages from sperm after ABVD chemotherapy in a patient with Hodgkin's lymphoma: sperm DNA and methylation profiling

ABSTRACT

Lymphomas represent one of the most common malignant diseases in young men and an important issue is how treatments will affect their reproductive health. It has been hypothesized that chemotherapies, similarly to environmental chemicals, may alter the spermatogenic epigenome. Here, we report the genomic and epigenomic profiling of the sperm DNA from a 31-year-old Hodgkin lymphoma patient who faced recurrent spontaneous miscarriages in his couple 11-26 months after receiving chemotherapy with adriamycin, bleomycin, vinblastine, and dacarbazine (ABVD). In order to capture the potential deleterious impact of the ABVD treatment on mutational and methylation changes, we compared sperm DNA before and 26 months after chemotherapy with whole-genome sequencing (WGS) and reduced representation bisulfite sequencing (RRBS). The WGS analysis identified 403 variants following ABVD treatment, including 28 linked to genes crucial for embryogenesis. However, none were found in coding regions, indicating no impact of chemotherapy on protein function. The RRBS analysis identified 99 high-quality differentially methylated regions (hqDMRs) for which methylation status changed upon chemotherapy. Those hqDRMs were associated with 87 differentially methylated genes, among which 14 are known to be important or expressed during embryo development. While no variants were detected in coding regions, promoter regions of several genes potentially important for embryo development contained variants or displayed an altered methylated status. These might in turn modify the corresponding gene expression and thus affect their function during key stages of embryogenesis, leading to potential developmental disorders or miscarriages.

Inequalities in Fertility-Impacting Cancer Incidence Among Young Populations in the United States

INTRODUCTION

Infertility is a concerning late effect of cancer and cancer treatments, yet referrals for fertility preservation are unequal across U.S. sociodemographic groups. Although all-site cancer incidence varies across U.S. sociodemographic groups, it is unclear whether fertility-impacting cancers, specifically, are unevenly distributed by sex or race/ethnicity.

METHODS

Cross-sectional analysis of cancer registry data from the Surveillance, Epidemiology, and End Results (SEER) Program (2010-2020). Age-specific demographic rates and negative binomial regression with an exposure for population size were employed to assess inequalities in the incidence rates of fertility-impacting cancers among U.S. individuals aged 39 and younger. Wald tests were used to compare coefficients across the multivariable negative binomial regression models.

RESULTS

Women had higher incidence rates of fertility-impacting cancers (cancers of the reproductive organs, cancers in areas proximal to the reproductive organs or that contribute to reproductive functioning, and other cancers identified in the literature as fertility-impacting) in the fully adjusted models. These associations differed from the patterns observed among all other types of cancers. The incidence rates of fertility-impacting cancers also varied by race/ethnic groups. However, the patterning observed by race-ethnicity varied between the three fertility-impacting cancer groups.

CONCLUSION

The burden of fertility-impacting cancers is unequal across sex and race/ethnic groups. The sociodemographic patterns observed in fertility-impacting cancers differ substantively from cancers that were not identified as fertility-impacting. The findings reinforce the importance of screening for fertility-impacting cancers and identify a potential unmet need for both fertility preservation referrals among cancer patients and access to fertility treatment for survivors of cancer.

Riluzole Reverses Blood-Testis Barrier Loss to Rescue Chemotherapy-Induced Male Infertility by Binding to TRPC

Cancer treatments, including cytotoxic therapy, often result in male infertility, necessitating the development of safe and effective strategies to preserve male reproductive potential during chemotherapy. Notably, our study uncovers the potential of repurposing riluzole, an FDA-approved drug for amyotrophic lateral sclerosis (ALS), in enhancing spermatogenesis. Hence, this research aims to explore the feasibility of utilizing riluzole to alleviate male infertility induced by busulfan (BSF), a commonly used chemotherapy drug. We established a BSF-induced oligospermia model in 4-week-old male mice and found that riluzole could effectively counter the detrimental effects of BSF on sperm production in mice with oligospermia. By restoring blood-testis barrier (BTB) functionality, riluzole improves sperm quality and reduces testicular atrophy. Through transcriptomic and molecular docking analyses, we identify transient receptor potential canonical subfamily member 5 (TRPC5) as a potential target for riluzole-mediated regulation of blood-testis barrier function. These findings propose riluzole as a promising therapeutic option for chemotherapy-induced male infertility, thereby addressing the fertility challenges associated with cancer treatments. Moreover, repurposing riluzole could streamline the drug development process, providing a cost-effective approach with reduced risk compared to developing entirely new drugs.

Prediction model of male reproductive function damage caused by CHOP chemotherapy regimen for non-Hodgkin's lymphoma

OBJECTIVE

The CHOP combined chemotherapy regimen (cyclophosphamide, doxorubicin, vincristine, and prednisone) is commonly used to treat non-Hodgkin Lymphoma (NHL). While these drugs are effective for cancer treatment, they may have side effects on the reproductive system that are poorly studied. This study used a mouse model to investigate the mechanisms of reproductive function impairment induced by the CHOP regimen and developed a predictive model for assessing reproductive damage with a non-invasive procedure.

METHODS

From 2022 to 2023, we statistically analyzed the changes of reproductive function of NHL patients before and after receiving CHOP regimen in the First Affiliated Hospital of Xiamen University. The NHL mouse model was established and divided into CHOP treatment group and control group. The weight of testis and epididymis, sperm quality and motility were compared between the two groups. Histopathological examination of testicular tissue was performed to determine pathological changes. ELISA was used to measure the expression of cytokines and cytokine pathways in serum, protein expression was analyzed by immunohistochemistry, and protein and mRNA levels of cytokines and pathways were evaluated by Western blotting and qPCR. Using stepwise regression method to select important factors, a prediction model of reproductive system damage was constructed.

RESULTS

Fifty-two NHL patients included in the questionnaire showed significant reproductive system damage after CHOP regimen treatment. The weight of testis and epididymis, as well as the number and vitality of sperm in the mouse model treatment group were significantly lower than those in the control group. Serum LH, FSH, estradiol and progesterone levels decreased significantly, while inhibin B levels increased significantly. There was no significant change in testosterone or prolactin levels. Inflammatory markers such as CSF-1, IL-1, IL-6, TGF-β1 and GDNF increased significantly, while the level of SOD1 decreased significantly. Immunohistochemical staining analysis showed that CAMP, Caspase3, CSF-1, GDNF, IL-1, IL-6, PRKACB, TGF-β1 and TXNDC5 were all expressed in spermatocytes, and the expression of therapeutic histones was significantly higher than that of the control group. Western blot analysis further detected the protein expression, and QPCR detected the mRNA content. The results showed that the expression of histone and mRNA in the treatment group was significantly higher than that in the control group. Stepwise regression method determined that estradiol (E2) was the most important variable in the prediction model, and the AUC for predicting reproductive damage was 1.

CONCLUSIONS

The CHOP regimen induces male reproductive toxicity, potentially mediated through alterations in hormone levels and increased expression of inflammatory cytokines and oxidative stress. Using E2 as the sole predictor in the model accurately predicts the extent of reproductive damage, offering a non-invasive method for detecting reproductive system damage.

Chemotherapy alone vs. chemotherapy plus radiotherapy in female adolescent and young adults with Hodgkin's lymphoma: reproductive health outcomes

PURPOSE

To examine the effects of Hodgkin's lymphoma and its treatment on reproductive health in female adolescent and young adults (AYA).

METHODS

We conducted a retrospective, population-based, matched-cohort study of female patients with Hodgkin's lymphoma diagnosed at 15-39 years of age from 1995 to 2014 in Ontario, Canada. Three female individuals with no history of cancer (unexposed) were matched by birth year and census subdivision to each patient with cancer (exposed). In a subset of the cohort (2005 onwards), the Hodgkin's lymphoma patients were further classified into two groups for analysis based on treatment exposure: (1) chemotherapy alone or (2) combined chemotherapy and radiation. Reproductive health outcomes were infertility, childbirth, and premature ovarian insufficiency (POI). Relative risks (RR) were calculated using modified Poisson regression adjusted for income quintile, immigration status, and parity.

RESULTS

A total of 1443 exposed and 4329 unexposed individuals formed our cohort. Hodgkin's lymphoma patients were at an increased risk of infertility (aRR 1.86; 95% CI 1.57 to 2.20) and POI (aRR 2.81; 95% CI 2.16 to 3.65). While the risk of infertility persisted in both treatment groups (chemotherapy alone, combined chemotherapy plus radiotherapy), the increased risk of POI was only statistically significant in the chemotherapy plus radiotherapy group. No differences in childbirth rates were observed, overall or by treatment exposure compared with unexposed individuals.

CONCLUSIONS

Female AYA survivors of Hodgkin's lymphoma face an increased risk of infertility, independent of exposure to chemotherapy alone, or chemotherapy plus radiotherapy. The risk of POI is higher in those requiring radiotherapy vs. chemotherapy alone.

IMPLICATIONS FOR CANCER SURVIVORS

These results emphasize the importance of pre-treatment fertility counseling and reproductive health surveillance for AYAs diagnosed with Hodgkin's lymphoma.

Protective effect of propolis on the antioxidant enzymes activities, characteristics of epididymal spermatozoa and histopathological structure of testis from rats treated with cyclophosphamide

El objetivo de este estudio fue evaluar el posible efecto terapéutico del propóleo sobre la peroxidación lipídica testicular inducida por ciclofosfamida (CP) y sobre los cambios asociados en los parámetros espermatológicos en los espermatozoides epididimarios y la estructura histopatológica de los testículos de rata. Las ratas se separaron aleatoriamente en 4 grupos con 7 ratas en cada grupo. Se formaron grupos como; 1.er grupo: grupo control (ratas no tratadas), 2.º grupo: grupo tratado con propóleo, 3.er grupo: grupo tratado con CP y 4.º grupo: grupo tratado con CP+propóleo. Se administró propóleo a las ratas en una dosis de 200 mg·kg bw -1 mediante alimentación forzada durante 7 días (d). Se administró CP a las ratas en una dosis única de 150 mg·kg pc -1 por vía intraperitoneal. La administración de propóleo se inició 2 días antes de la administración de CP y continuó durante 7 días. Niveles de malondialdehído (MDA) y glutatión reducido (GSH), actividades de catalasa (CAT), glutatión peroxidasa (GSH-Px), glutatión S-transferasa (GST) y superóxido dismutasa (SOD), parámetros espermatológicos, peso de los órganos reproductivos. y se determinó la estructura histopatológica. En comparación con el grupo de control, los niveles de MDA y las actividades de SOD aumentaron significativamente; Si bien las actividades de CAT y GST disminuyeron, no se encontraron cambios en los niveles de GSH ni en las actividades de GSH-Px en el grupo CP. En el grupo tratado con CP, hubo una disminución en la motilidad de los espermatozoides del epidídimo, la densidad de los espermatozoides en los espermatozoides del epidídimo y el peso de los testículos, la próstata, el epidídimo y la vesícula seminal; mientras que hubo un aumento en la proporción de espermatozoides anormales en comparación con el grupo de control en los espermatozoides epididimarios. El propóleo normalizó los parámetros bioquímicos y espermatológicos en los espermatozoides epididimarios. El examen histopatológico del tejido testicular mostró que los cambios histopatológicos más significativos, como restos celulares, invaginación y degeneración, ocurrieron en el grupo CP. En la patogénesis de la toxicidad testicular inducida por la PC puede desempeñar un papel el deterioro del equilibrio oxidante-antioxidante y el propóleo puede reducir los efectos secundarios graves de las alteraciones inducidas por la PC.

How I Follow Hodgkin Lymphoma in First Complete (Metabolic) Remission?

Hodgkin lymphoma is characterized by a high cure rate in the modern era of medicine regardless of stage, but patients suffer from a high risk of comorbidity associated with the administered therapy. The main aim of this review article is to assess and analyze the various comorbidities associated with Hodgkin lymphoma and address the survivorship of patients, including fertility, secondary cancers due to cardiovascular toxicity, and quality of life. Furthermore, this review explores the optimal strategy for detecting relapse. The treatment paradigm of Hodgkin lymphoma has shifted, with a paradigm shift toward achieving a high cure rate and low toxicity as a standard of care in this patient population. Checkpoint inhibitors, especially nivolumab, in combination with chemotherapy are increasingly being studied in the first line of therapy. However, their long-term toxicity remains to be assessed in longer follow-up. In conclusion, Hodgkin lymphoma survivors, regardless of their treatment, should be followed up individually by a multidisciplinary survivorship team in order to detect and properly treat the long-term side effects of therapy.

Management of limited-stage Hodgkin lymphoma

Hodgkin lymphoma (HL) is a rare type of B-cell malignancy with bimodal age distribution targeting young adults and elderly. Prognostic models are available to identify risk of recurrence and response to treatment. Currently, positron emission tomography scanning is most useful in optimizing therapy. Outcomes are generally excellent with standard chemotherapy or combined modality therapy. Balancing efficacy and the risk of late effects in Hodgkin lymphoma is essential, including early detection of potential complications. Incorporation of novel therapies such as brentuximab vedotin and checkpoint inhibitors are being explored in the frontline setting, having already demonstrated improved survival and tolerable toxicity in advanced HL. Furthermore, the addition of these agents have the potential to transform treatment paradigms for early-stage HL and may result in improved outcomes with decreased risks of late toxicities that continue to afflict long-term survivors. However, the patient population, sequencing, and combinations with cytotoxic chemotherapy all remain still standing questions as results of current and upcoming randomized trials are awaited. In this article, we discuss the current data on the approach to initial treatment of early-stage classical HL, review toxicity profiles, and examine upcoming novel therapy trials.

Preservation of fertility in female patients with hematologic diseases

Recent developments of assisted reproduction techniques turned possible to avoid the infertility consequences of oncologic treatments, but fertility preservation (FP) has been somewhat neglected in women with hematologic diseases undergoing gonadotoxic treatments. For these specific cases, the current options for FP include the cryopreservation of embryos, mature oocytes and ovarian tissue, and oocyte in-vitro maturation. We intend to make patients and clinicians aware of this important and relevant issue, and provide hematologists, assisted reproduction physicians and patients, with updated tools to guide decisions for FP. The physicians of the units responsible for female FP should always be available to decide on the best-individualized FP option in strict collaboration with hematologists. With a wide range of options for FP tailored to each case, a greater level of training and information is needed among clinicians, so that patients proposed to gonadotoxic treatments can be previously advised for FP techniques in hematological conditions. ABBREVIATED ABSTRACT: Recent developments of assisted reproduction techniques turned possible to preserve the fertility of women with hematologic diseases undergoing gonadotoxic treatments. Current options for fertility preservation in women with hematologic diseases are presented. It is imperative to offer fertility preservation to all women before starting any gonadotoxic treatment and in some cases after treatment. Fertility preservation methods enable to later achieve the desired pregnancy.

Hodgkin lymphoma and female fertility: a multicenter study in women treated with doxorubicin, bleomycin, vinblastine, and dacarbazine

Preservation of fertility has become a growing concern in young females with Hodgkin lymphoma (HL). However, the rate of pregnancy after the current most frequently prescribed ABVD (doxorubicin [Adriamycin], bleomycin, vinblastine, and darcarbazine) chemotherapy for HL has rarely been studied. In this study, we aim to determine the impact of ABVD on the fertility of women treated for HL. We conducted a noninterventional, multicenter study of female patients of childbearing age who were treated for HL. Two healthy apparied women nonexposed to chemotherapy (our controls) were assigned for each patient. Fertility was assessed by the number of pregnancies and births after HL treatment. Sixty-seven patients were included. The median age at diagnosis was 24.4 years (range, 16-43). HL was a localized disease for 68.7%. Of all the patients, 53.7% started at least 1 pregnancy after treatment vs 54.5% of the controls (P = .92). Of all the patients who desired children, 81% had at least 1 pregnancy. Patients treated with ABVD did not have a longer median time to pregnancy (4.8 years in the group of patients and 6.8 years for controls). Across patients, there were 58 pregnancies and 48 births (ratio, 1:2) and 136 pregnancies and 104 births (ratio, 1:3) for the control cohort. No increase in obstetric or neonatal complications has been reported in HL in our study. The number of pregnancies, births, and the time to start a pregnancy in young women treated with ABVD for HL is not different from that of controls. Therefore, females with HL treated with ABVD should be reassured regarding fertility.

Fertility preservation in pediatric leukemia and lymphoma: A report from the Children's Oncology Group

Certain chemotherapy agents, radiation, and surgery can all negatively impact future fertility. Consults regarding treatment-related risk for infertility and gonadal late effects of these agents should occur at the time of diagnosis as well as during survivorship. Counseling on fertility risk has traditionally varied significantly across providers and institutions. We aim to provide a guide to standardize the assignment of gonadotoxic risk, which can be used in counseling patients both at the time of diagnosis and in survivorship. Gonadotoxic therapies were abstracted from 26 frontline Children's Oncology Group (COG) phase III protocols for leukemia/lymphoma, in use from 2000-2022. A stratification system based on gonadotoxic therapies, sex, and pubertal status was used to assign treatments into minimal, significant, and high level of increased risk for gonadal dysfunction/infertility. Risk levels were assigned to protocols and different treatment arms to aid oncologists and survivor care providers in counseling patients regarding treatment-related gonadotoxicity. Males were most commonly at high risk, with at least one high-risk arm in 14/26 protocols (54%), followed by pubertal females (23% of protocols) and prepubertal females (15% of protocols). All patients who received direct gonadal radiation or hematopoietic stem cell transplant (HSCT) were considered at high risk. Partnering with patients and their oncology/survivorship team is imperative for effective fertility counseling both prior to and post treatment, and this comprehensive guide can be used as a tool to standardize and improve reproductive health counseling in patients undergoing COG-based leukemia/lymphoma care.

Hodgkin Lymphoma in Children and Adolescents of Northern Greece: 25-Year Results and Long-term Follow-up

Aim of this study was to evaluate the long-term therapeutic outcome and treatment-related complications in Hodgkin disease. We reviewed the medical records of 93 patients diagnosed with classic Hodgkin lymphoma, treated, and followed-up during the last 25 years. The cohort study included 49 males and 44 females with median age 11.8 years old (range: 3.95 to 17.42 y). The most common subtype was nodular sclerosis in 47/93 (50.5%). B symptoms were present in 15/93 (16.1%). From January 2009 until December 2020, 55 (59%) patients diagnosed with Hodgkin lymphoma were treated according to European Network for Pediatric Hodgkin Lymphoma (EURONET)-PHL-C1 protocol. Concerning outcome, a total of 89/93 patients are alive. Relapse occurred in 7/93. Second malignancies are reported in a total of 5 patients, 3 solid tumors (thyroid cancer, breast cancer, and osteosarcoma), and 2 acute myeloid leukemias. The overall survival and event-free survival for the whole cohort were 95.7% and 83.9%, respectively. Disease-free survival was 92.5%. Although a considerable high fraction of patients with Hodgkin disease can achieve continuous complete remission, they are at a high risk of developing long-term treatment-related complications. High curative rates as well as prevention of late effects can be achieved by implementation of individualized treatment strategies and innovative treatments.

Reproductive Issues in Long-Term Surviving Patients following Therapy for Hodgkin’s Disease in the Republic of North Macedonia: Risks of Infertility According to First-Line Treatment Regimens

Infertility as a consequence of therapy presents a high psychosocial burden for HL patients. In the cohort of our analyzed patients, within the post-ABVD surviving patients, alterations of the spermogram were documented in a total of 6.1% of the male patients and 5.4% of the female patients developed amenorrhea. On the other hand, within the subgroup of surviving patients following BEACOPP chemotherapy, 60% of the male patients manifested defects in their spermogram, and as high as 28.6% of the female survivors reported loss of their monthly cycle. It has been reported on several occasions that even prior to treatment, the sperm of HL patients manifests poorer quality characteristics when analyzed against control specimens from healthy male donors. The analyzed results in ABVD-treated male HL patients confirm ABVD to be a safe regimen for males of all age categories, as well as for female patients under the age of thirty. In women above the age of 30, the infertility risk rate is relatively low (14%), which leaves the decision of preserving fertility to themselves. For all BEACOPP-treated female, as well as male patients, a consult with a reproductive medicine specialist is warranted prior to therapy, due to the high infertility risk, and the final decision should be made on an individual basis.

Reduction of the Vertebral Bone Mineral Density in Patients with Hodgkin Lymphoma Correlates with Their Age and the Treatment Regimen They Received

Simple Summary

Hodgkin lymphoma (HL) is considered a largely curable disease (~80%). The young patient age at diagnosis and their long life expectancy make quality-of-life issues, including osteopenia, exceedingly important. This study aimed to assess treatment-related bone mineral density (BMD) changes that are overlooked in this young population. BMD was measured using PET/CT scans. Among 213 patients (median age 29 years), post-treatment BMD reduction of >15% was significantly more common in those aged ≥30 years and was also associated with a cumulative dose of steroids used. At 6 months post-therapy, BMD recovery was observed in ABVD (adriamycin/bleomycin/vinblastine/dacarbazine) treated patients, while individuals receiving EB (bleomycin/etoposide/adriamycin/cyclophosphamide/oncovin/procarbazine/prednisone) regimens demonstrated persistent BMD loss and higher rates of osteopenia. Our findings suggest that steroid use should be minimized and highly gonadotoxic drugs like procarbazine should be substituted with less toxic ones, due to their deleterious effect on BMD. Adequate vitamin D levels should be maintained.

Abstract

Nowadays, Hodgkin lymphoma (HL) has become highly curable. The young age at diagnosis and long life expectancy emphasize the importance of preventing long-term treatment side effects, including bone mineral density (BMD) loss, in these patients. We aimed to evaluate the effects of first-line therapeutic modalities on BMD dynamics in HL patients, intending to identify individuals at risk for osteopenia. Demographics, HL risk factors, treatment, including cumulative steroid doses, and BMD of 213 newly-diagnosed HL patients (median age 29 years), treated at Rambam between 2008–2016, were analyzed. The main chemotherapy regimens applied were: ABVD (adriamycin, bleomycin, vinblastine, dacarbazine) and escalated BEACOPP (EB; bleomycin, etoposide, adriamycin, cyclophosphamide, oncovin, procarbazine, prednisone). BMD was measured using PET/CT scans. BMD loss >15% was revealed in 48% of patients at therapy completion, with osteopenia prevalence of 4% and 14% at baseline and post-therapy, respectively. Cumulative hydrocortisone equivalent doses >3400 mg/m² correlated with significant BMD reduction. Multivariate analysis at 6 months post-therapy identified age ≥30 years and EB-regimens as significant risk factors for BMD decrease >15%. Therapy-related BMD loss is common in HL patients. Its persistence is associated with age ≥30 years and EB treatment. Reduction of cumulative steroid doses and switch to non-gonadotoxic drugs should be considered.

Classical Hodgkin lymphoma

Classical Hodgkin lymphoma is one of the more frequent lymphomas and is generally considered a highly curable disease with standard first-line chemotherapy and radiotherapy in some cases. Despite these outstanding results, major problems remain unresolved. First, there are still patients who will not be cured with front-line regimens and, second, many patients who are cured of classical Hodgkin lymphoma continue to die prematurely due to the late toxic effects of their therapy. Because the median age of patients with classical Hodgkin lymphoma is in the mid-30s, the disease's impact on the number of years lost from productive life is remarkable. In recent years, the gold standard of chemotherapy (often combined with radiotherapy) has changed, with the approval of immunotherapy mostly in relapse settings.

Longitudinal study of AMH variations in 122 Adolescents and Young Adults (AYA) and non-AYA lymphoma patients to evaluate the chemo-induced ovarian toxicity to further personalise fertility preservation counselling

STUDY QUESTION

What is the influence of age and chemotherapy regimen on the longitudinal blood anti-Müllerian hormone (AMH) variations in a large series of adolescents and young adult (AYA) (15-24 years old) and non-AYA (25-35 years old) lymphoma patients?

SUMMARY ANSWER

In case of alkylating regimen treatment, there was a deep and sustained follicular depletion in AYA as well as non-AYA patients; however in both groups, the ovarian toxicity was extremely low in cases of non-alkylating treatments.

WHAT IS KNOWN ALREADY

AMH is now well-recognised to be a real-time indicator of ovarian follicular depletion and recovery in women treated by chemotherapy. Its longitudinal variations may discriminate between highly and minimally toxic protocols regarding ovarian function. It has been shown, in different cancer types, that age, type of chemotherapy regimen and pre-treatment AMH levels are the main predictors of ovarian recovery. Large studies on longitudinal AMH variations under chemotherapy in lymphoma patients are few but can provide the opportunity to assess the degree of follicle loss at a young age.

STUDY DESIGN, SIZE, DURATION

This prospective cohort study was conducted in the Fertility Observatory of the Lille University Hospital. Data were collected between 2007 and 2016. Non-Hodgkin or Hodgkin lymphoma patients (n = 122) between 15 and 35 years old were prospectively recruited before commencing chemotherapy. Patients were treated either by a non-alkylating protocol (ABVD group; n = 67) or by an alkylating regimen (alkylating group; n = 55).

PARTICIPANTS/MATERIALS, SETTING, METHODS

Serial AMH measurements were performed at baseline (AMH0), 15 days after the start of chemotherapy (AMH1), 15 days before the last chemotherapy cycle (AMH2), and at time 3, 6, 9, 12, 18 and 24 months from the end of chemotherapy. The whole study population was divided into two groups according to age: AYA (15-24; n = 65) and non-AYA (25-35; n = 57). All patients received a once monthly GnRH agonist injection during the whole treatment period. A linear mixed model was used to account for the repeated measures of single patients.

MAIN RESULTS AND THE ROLE OF CHANCE

At baseline, non-AYA patients had higher BMI and lower AMH levels than AYA patients. All AYA and non-AYA patients having received ABVD protocols had regular cycles at 12 months of follow-up. In case of alkylating regimens, amenorrhoea was more frequent in non-AYA patients than in AYA patients at 12 months (37% vs 4%, P = 0.011) and at 24 months (24% vs 4%, P = 0.045). We distinguished a similar depletion phase from AMH0 to AMH2 between ABVD and alkylating groups but significantly different recovery phases from AMH2 to AMH + 24 months. AMH recovery was fast and complete in case of ABVD protocols whatever the age: AMH reached pre-treatment values as soon as the 6th month of follow-up in the AYA group (mean (95% CI) in log AMH M0 vs M6: 3.07 (2.86 to 3.27) vs 3.05 (2.78 to 3.31), P = 1.00) and in the non-AYA group (mean (95% CI) in log AMH M0 vs M6: 2.73 (2.40 to 3.05) vs 2.47 (2.21 to 2.74), P = 1.00). In contrast, no patients from the alkylating group returned to pre-treatment AMH values whatever the age of patients (AYA or non-AYA). Moreover, none of the AMH values post-chemotherapy in the non-AYA group were significantly different from AMH2. Conversely in the AYA group, AMH levels from 6 months (mean (95% CI) in log AMH: 1.79 (1.47 to 2.11), P < 0.001) to 24 months (mean (95% CI) in log AMH: 2.16 (1.80 to 2.52), P ≤ 0.001) were significantly higher than AMH2 (mean (95% CI) in log AMH: 1.13 (0.89 to 1.38)). Considering the whole study population (AYA and non-AYA), pre-treatment AMH levels influenced the pattern of the AMH variation both in alkylating and ABVD protocols (interaction P-value = 0.005 and 0.043, respectively). Likewise, age was significantly associated with the pattern of the recovery phase but only in the alkylating group (interaction P-value =0.001). BMI had no influence on the AMH recovery phase whatever the protocol (interaction P-value = 0.98 in alkylating group, 0.72 in ABVD group).

LIMITATIONS, REASONS FOR CAUTION

There was a large disparity in subtypes of protocols in the alkylating group. The average duration of chemotherapy for patients treated with alkylating protocols was longer than that for patients treated with ABVD.

WIDER IMPLICATIONS OF THE FINDINGS

These results make it possible to develop strategies for fertility preservation according to age and type of protocol in a large series of young lymphoma patients. In addition, it was confirmed that young age does not protect against ovarian damage caused by alkylating agents.

STUDY FUNDING/COMPETING INTEREST(S)

This work was supported by Agence Régionale de Santé Hauts de France and Agence Onco Hauts-de-France who provided finances for AMH dosages (n° DOS/SDES/AR/FIR/2019/282). There are no competing interests.

The Case of Billy Best: 25 Years Later

Billy Best was diagnosed with Hodgkin lymphoma in 1994 at age 16 and became well-known when he ran away from home to avoid receiving further chemotherapy. His story became national news when, with the support of his adopted parents, he returned home and opted to use complementary and alternative medicine (CAM) instead of standard chemotherapy and radiation for his cancer treatment. Now 25 years since Billy Best entered the public eye, his story is one that is frequently referenced in pediatrics, bioethics, and other related fields. Here, the authors examine the evolution of various features of this case, including treatment of Hodgkin lymphoma, the interplay between medicine and the media, the role of CAM in pediatric care, navigating entrenched disagreements and how best to integrate adolescents into health care decision-making, and the role of narrative in medical practice. The authors explore the unique role of each of these facets of Billy Best's case, describing how each has or has not changed in the quarter century since that time amid the changing landscape of pediatric health care. Ultimately, although many advances have occurred since Billy Best's time, significant work remains. Additional effort will be required in the future to optimize communication, improve treatment toxicities from Hodgkin lymphoma without decreasing survival, integrate the voice and perspective of adolescents into their treatment decisions, and navigate the roles of CAM and the media in pediatric health care.

Male and Female Fertility: Prevention and Monitoring Hodgkin' Lymphoma and Diffuse Large B-Cell Lymphoma Adult Survivors. A Systematic Review by the Fondazione Italiana Linfomi

BACKGROUND

Adult patients with Hodgkin lymphoma (HL) and diffuse large B-cell lymphoma (DLBCL) have prolonged survival but face the risk of treatment-induced impaired fertility. This systematic review, conducted by Fondazione Italiana Linfomi (FIL) researchers, aims to evaluate the incidence of treatment-related infertility, fertility preservation options, fertility assessment measures, and the optimal interval between the end of treatment and conception.

METHODS

MEDLINE, the Cochrane Library, and EMBASE were systematically searched up to September 2020 for published cohort, case-control, and cross-sectional studies on fertility issues.

RESULTS

Forty-five eligible studies were identified. Gonadotoxicity was related to sex, type and dosage of treatment, and, in females, to age. After receiving alkylating-agent-containing regimens, less than 30% of males recovered spermatogenesis, and 45% of females ≥30 years in age retained regular menstrual cycles. Sperm cryopreservation was offered to the majority of patients; sperm utilization resulted in a 33-61% pregnancy rate. After ovarian tissue transplantation, the spontaneous pregnancy and live birth rates were 38% and 23%; after IVF, the live birth rate was 38.4%. No data could be extracted on the utilization rate of cryopreserved mature oocytes. The results of studies on GnRH analogs are controversial; therefore, their use should not be considered an alternative to established cryopreservation techniques. Sperm count, FSH, and inhibin-B levels were appropriate measures to investigate male fertility; serum AMH levels and antral follicle count were the most appropriate markers for ovarian reserve. No data could be found regarding the optimal interval between the end of treatment and conception.

CONCLUSIONS

The risk of infertility should be discussed with adult lymphoma patients at the time of diagnosis, and fertility preservation options should be proposed before first-line treatment with alkylating-agent-containing regimens.

ABVD and BEACOPP regimens' effects on fertility in young males with Hodgkin lymphoma

PURPOSE

Considering the increased cancer patient survivorship, the focus is now on addressing the impacts of treatment on quality of life. In young people, altered reproductive function is a major issue and its effects in young males are largely neglected by novel research. To improve clinician awareness, we systematically reviewed side effects of chemotherapy for Hodgkin lymphoma (HL) in young males.

METHODS

The review was prospectively registered (PROSPERO N. CRD42019122868). Three databases (Medline via PUBMED, SCOPUS, and Cochrane Library) were searched for studies featuring males aged 13-51-years who underwent chemotherapy for HL using ABVD (Adriamycin® (doxorubicin), bleomycin, vinblastine, and dacarbazine) or BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisolone) regimens. These chemotherapy regimens were compared against each other using sperm characteristics, FSH, and inhibin B levels to measure fertility levels.

RESULTS

Data were extracted from five studies featuring 1344 patients. 6 months post-ABVD saw marked deterioration in sperm count, further reduced by more cycles (P = 0.05). Patients treated with BEACOPP rather than ABVD were more prone to oligospermia. Receiving fewer cycles of both regimens increased the likelihood of sperm production recovering. Patients treated with 6-8 cycles of BEACOPP did not recover spermiogenesis.

CONCLUSIONS

ABVD and BEACOPP regimens significantly reduce fertility function to varying effects depending on treatment duration. ABVD temporarily causes significant reductions in male fertility, whereas BEACOPP's effects are more permanent. Therefore, clinicians should discuss fertility preservation with male patients receiving infertility-inducing gonadotoxic therapy. Further high-quality studies are required to more adequality describe the risk to fertility by chemotherapy.

A Descriptive Study Exploring Semen Quality Among Indian Cancer Patients

Purpose: To descriptively explore semen quality among Indian men with various types of malignancies. We evaluated semen parameters of male patients referred to our hospital before commencing their cancer treatment. Methods: Four hundred sixty-one male patients who were within the age range of 15-50 years were recruited with diagnosed malignancies. Pre-treatment semen analyses were performed on these patients to collect data on the volume, sperm concentration, motility, and normal forms (morphology). These semen parameters were compared between cancer groups (testicular cancer, hematological cancer, and other cancers). Further comparisons were also drawn to World Health Organization (WHO) semen parameter levels (2010, fifth edition) for normal outcomes. Results: There were no notable variations observed in semen volume (mL) and progressive motility (%) between cancer groups. These parameters were within the WHO normal semen criteria. Differences in normal forms (%) between cancer groups were not observed either; however, they were marginally lower compared with the WHO criteria. Sperm concentration was evidently lower in testicular cancer 34 × 10⁶/mL (IQR: 10.1-60 × 10⁶/mL) compared with hematological cancers 66 × 10⁶/mL (IQR: 23-84.21 × 10⁶/mL) and other cancers (IQR: 27-86.3 × 10⁶/mL). Testicular cancer patients also presented with the largest semen disorder diagnosis (Asthenozoospermia, Oligoasthenozoospermia, Oligozoospermia, and Azoospermia) compared with two other groups. Conclusion: Males with testicular cancer have shown to have lower semen quality between cancer groups and compared with WHO criteria, increasing their likelihood of them being infertile. This study further allows us to understand these outcomes, particularly in the Indian subpopulation, propagating changes in guidelines in oncofertility and medical counseling.

Ovaries of patients recently treated with alkylating agent chemotherapy indicate the presence of acute follicle activation, elucidating its role among other proposed mechanisms of follicle loss

OBJECTIVE

To investigate mechanisms of primordial follicle (PMF) loss in vivo in human ovaries shortly after alkylating agent (AA) chemotherapy.

DESIGN

Cohort study.

SETTING

Tertiary university medical center.

PATIENT(S)

Ninety-six women aged 15-39 years who underwent ovarian tissue cryopreservation for fertility preservation.

INTERVENTION(S)

Fresh ovarian tissue samples were harvested from women treated with AA (n = 24) or non-AA (n = 24) chemotherapy <6 months after treatment and age-matched untreated women (n = 48).

MAIN OUTCOME MEASURE(S)

Differential follicle counts, time from chemotherapy exposure, immunostaining for apoptosis (cleaved caspase-3) and FOXO3A on tissue harvested within ultrashort time intervals (4-12 days), collagen (Sirius red) and neovascularization (CD34).

RESULT(S)

AA-treated ovaries had significant loss of PMFs, and significant increase in absolute numbers of growing follicles compared with untreated control ovaries. The number of growing follicles was inversely correlated with time from chemotherapy. Representative staining for FOXO3A observed decreased nuclear localization in PMF oocytes in AA-treated ovaries removed within the ultrashort time interval compared with untreated ovaries. Neither significant loss of PMFs, increase in growing follicles, nor decrease in nuclear FOXO3A were observed in non-AA-treated ovaries. No increased expression of cleaved caspase-3 was seen in PMFs within the ultrashort time interval after AA or non-AA chemotherapy. Significant stromal fibrosis and neovascularization were observed in AA-treated ovaries only after follicle loss had already occurred (4-6 months).

CONCLUSION(S)

Follicle activation occurs in vivo in ovaries of patients treated with AA, indicating a pathologic mechanism which may contribute to chemotherapy-induced follicle loss.

Advances in the Treatment and Prevention of Chemotherapy-Induced Ovarian Toxicity

Due to improvements in chemotherapeutic agents, cancer treatment efficacy and cancer patient survival rates have greatly improved, but unfortunately gonadal damage remains a major complication. Gonadotoxic chemotherapy, including alkylating agents during reproductive age, can lead to iatrogenic premature ovarian insufficiency (POI), and loss of fertility. In recent years, the demand for fertility preservation has increased dramatically among female cancer patients. Currently, embryo and oocyte cryopreservation are the only established options for fertility preservation in women. However, there is growing evidence for other experimental techniques including ovarian tissue cryopreservation, oocyte in vitro maturation, artificial ovaries, stem cell technologies, and ovarian suppression. To prevent fertility loss in women with cancer, individualized fertility preservation options including established and experimental techniques that take into consideration the patient's age, marital status, chemotherapy regimen, and the possibility of treatment delay should be provided. In addition, effective multidisciplinary oncofertility strategies that involve a highly skilled and experienced oncofertility team consisting of medical oncologists, gynecologists, reproductive biologists, surgical oncologists, patient care coordinators, and research scientists are necessary to provide cancer patients with high-quality care.

PET-adapted approaches to primary therapy for advanced Hodgkin lymphoma

Recent results of randomized phase III studies of FDG-PET-adapted therapy for advanced Hodgkin lymphoma (HL) have clearly demonstrated benefit to alteration of treatment according to interim response, in particular regarding reducing toxicity while maintaining efficacy. However, these studies have differences in design including initial chemotherapy regimen, PET response criteria, patient populations enrolled, and inclusion of radiation, and report different results regarding efficacy and toxicities, which makes cross-trial comparisons difficult. Practitioners are presented with deciding which of these approaches will provide the optimum outcome, balancing toxicity and efficacy, and for which patient with advanced-stage HL. This review summarizes the observations reported from these trials and provides context to help guide physicians and patients in treatment decisions for advanced HL.

Resources-Stratified Guidelines for Classical Hodgkin Lymphoma

Hodgkin lymphoma is a haematological malignancy predominantly affecting young adults. Hodgkin lymphoma is a highly curable disease by current treatment standards. Latest treatment guidelines for Hodgkin lymphoma however imply access to diagnostic and treatment modalities that may not be available in settings with restricted healthcare resources. Considerable discrepancies in Hodgkin lymphoma patient survival exist, with poorer outcomes reported in resources-constrained settings. Resources-stratified guidelines for diagnosis, staging and treatment of Hodgkin lymphoma were derived in an effort to optimize patient outcome provided a given setting of available resources. These guidelines were derived based on the framework of the Breast Health Global Initiative stratifying resource levels in basic, core, advanced and maximal categories.

Use of antioxidant could ameliorate the negative impact of etoposide on human sperm DNA during chemotherapy

RESEARCH QUESTION

A previous study showed that N-acetylcysteine (NAC), used after in-vitro exposure to the gonadotoxic chemotherapeutic drug etoposide, has the ability to decrease DNA damage in human spermatozoa; however, it showed no benefit when used before exposure. This study aimed to evaluate the impact of the NAC on the preservation of sperm quality during in-vitro exposure to etoposide.

DESIGN

Twenty semen samples were submitted to four experimental conditions: control, NAC-only incubation, etoposide-only incubation, and concomitant etoposide and NAC incubation. After in-vitro incubation, semen parameters, sperm chromatin condensation, sperm DNA fragmentation, sperm oxidative stress and sperm metabolism were used to evaluate the role of NAC in protecting human spermatozoa from etoposide.

RESULTS

Etoposide did not affect semen parameters, nor did it cause sperm oxidative damage or alterations in glycolytic profile. However, it induced chromatin decondensation and DNA fragmentation, which were fully prevented by NAC.

CONCLUSIONS

NAC was able to protect sperm DNA integrity during etoposide treatment in vitro, suggesting that NAC may be useful as an adjuvant agent in preserving male fertility during chemotherapy treatments.

Contemporary treatment options for a classical disease: Advanced Hodgkin lymphoma

Advanced classical Hodgkin lymphoma (cHL) is a rare lymphoid disease characterized by the presence of Hodgkin and Reed-Sternberg (HRS) cells. Each year, cHL accounts for 0.5% of all new cancer diagnoses and about 80% are diagnosed with advanced stage disease. Given the significant improvement in cure rates, the focus of treatment has shifted towards minimization of acute and long-term toxicities. PET-adapted strategies have largely been adopted as standard of care in the United States in an attempt to balance toxicities with adequate lymphoma control. However, the appropriate upfront chemotherapy regimen (ABVD versus eBEACOPP) remains controversial.

A systematic review of radiation-induced testicular toxicities following radiotherapy for prostate cancer

BACKGROUND

Prostate cancer is the second most common malignancy in men in the world, and radiotherapy is used as a standard treatment modality for this cancer. Although this treatment modality effectively kills prostate cancerous cells, it unavoidably irradiates the organs/tissues that are away from the treatment site. In this regard, radiation-induced testicular toxicities following prostate radiotherapy can affect sexual function, reproduction, and quality of life in cancer survivors. This review summarizes the available data on testicular exposure to radiation during prostate radiotherapy and the consequences on testicular function.

METHODS

To illuminate the radiation-induced testicular toxicities following prostate radiotherapy, a systematic search was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline in PubMed, Web of Science, Scopus, Embase, and clinical trials electronic databases up to September 2018. According to a set of prespecified inclusion and exclusion criteria, 31 eligible articles providing data on testicular function following radiotherapy in patients with prostate cancer were included in the study.

RESULTS

According to the different radiotherapeutic techniques used for prostate cancer treatment, the total tumor dose and scattered testicular dose values were ranging from 36.25 to 78.00 Gy and 0.06 to 6.48 Gy, respectively. Luteinizing hormone and follicle-stimulating hormone levels after prostate radiotherapy were significantly higher in comparison with the pretreatment levels. Around 60% of the studies showed that testosterone levels after prostate radiotherapy were significantly lower than the pretreatment levels. Furthermore, erectile dysfunction (ED), as an adverse side effect resulting from prostate radiotherapy, was reported and this complication is significantly correlated with lower satisfaction with sexual life. Testicular atrophy following prostate radiotherapy has also been observed and its frequency in patients with prior prostate radiotherapy is 2.5 times more than that in the patients without prior radiotherapy.

CONCLUSION

The data revealed that the scattered dose to testicular tissues during prostate radiotherapy can lead to testicular atrophy, variation of the male sex hormones, and quality of sexual life.

Doxorubicin obliterates mouse ovarian reserve through both primordial follicle atresia and overactivation

Ovarian toxicity and infertility are major side effects of cancer therapy in young female cancer patients. We and others have previously demonstrated that doxorubicin (DOX), one of the most widely used chemotherapeutic chemicals, has a dose-dependent toxicity on growing follicles. However, it is not fully understood if the primordial follicles are the direct or indirect target of DOX. Using both prepubertal and young adult female mouse models, we comprehensively investigated the effect of DOX on all developmental stages of follicles, determined the impact of DOX on primordial follicle survival, activation, and development, as well as compared the impact of age on DOX-induced ovarian toxicity. Twenty-one-day-old CD-1 female mice were intraperitoneally injected with PBS or clinically relevant dose of DOX at 10 mg/kg once. Results indicated that DOX primarily damaged granulosa cells in growing follicles and oocytes in primordial follicles and DOX-induced growing follicle apoptosis was associated with the primordial follicle overactivation. Using the 5-day-old female mice with a more uniform primordial follicle population, our data revealed that DOX also directly promoted primordial follicle death and the DNA damage-TAp63α-C-CASP3 pathway was involved in DOX-induced primordial follicle oocyte apoptosis. Compared to 21-day- and 8-week-old female mice that were treated with the same dose of DOX, the 5-day-old mice had the most severe primordial follicle loss as well as the least degree of primordial follicle overactivation. Taken together, these results demonstrate that DOX obliterates mouse ovarian reserve through both primordial follicle atresia and overactivation and the DOX-induced ovarian toxicity is age dependent.

Menstrual blood derived mesenchymal stem cells combined with Bushen Tiaochong recipe improved chemotherapy-induced premature ovarian failure in mice by inhibiting GADD45b expression in the cell cycle pathway

BACKGROUND

To investigate the therapeutic effects of menstrual blood derived mesenchymal stem cells (MB-MSCs) combined with Bushen Tiaochong recipe (BSTCR) on epirubicin induced premature ovarian failure (POF) in mice.

METHODS

Twenty-four female C57BL/6 mice of 6-8 weeks were intraperitoneally injected with epirubicin to induce POF, and then they were randomized into 4 groups of 6 mice each and treated with PBS, MB-MSCs, BSTCR, and MB-MSCs combined with BSTCR, respectively. Six mice of the same age were used as controls. Vaginal smear, TUNEL and hematoxylin-eosin staining were to observe estrous cycles, ovarian cell apoptosis and follicles. Enzyme-linked immunosorbent analysis determined serum estradiol, follicle-stimulating hormone (FSH) and anti-Müllerian hormone (AMH) levels. RT-qPCR and Western Blot analysis were to determine GADD45b, CyclinB1, CDC2 and pCDC2 expressions.

RESULTS

Epirubicin treatment resulted in a decrease in the number of primordial, primary, secondary and antral follicles, an increase in the number of atretic follicles and ovarian cell apoptosis, a decrease in estradiol and AMH levels, an increase in FSH levels, and estrous cycle arrest. However, MB-MSCs combined with BSTCR rescued epirubicin induced POF through down-regulating GADD45b and pCDC2 expressions, and up-regulating CyclinB1 and CDC2 expressions. The combined treatment showed better therapeutic efficacy than BSTCR or MB-MSCs alone.

CONCLUSIONS

MB-MSCs combined with BSTCR improved the ovarian function of epirubicin induced POF mice, which might be related to the inhibition of GADD45b expression and the promotion of CyclinB1 and CDC2 expressions. The combined treatment had better therapeutic efficacy than BSTCR or MB-MSCs alone.

The role of flavonoid antioxidant, morin in improving procarbazine-induced oxidative stress on testicular function in rat

BACKGROUND

Procarbazine (PCZ) is an effective chemotherapeutic drug used in the treatment of lymphoma; however, oxidative stress-mediated testicular toxicity is a major side effect. Recently, therapeutic intervention using flavonoids against oxidative stress-related pathologies is gaining more attention. Morin (MOR) is a natural flavonoid with proven antioxidant activity. This study was designed therefore to evaluate the potential role of MOR in ameliorating PCZ-induced testicular oxidative stress and altered sperm quality in rat model.

METHODS

A total of 24 male Wistar rats (170-180 g) were randomly assigned into 4 treatment groups: I, control; II, PCZ (2 mg/kg b.w.); III, PCZ (2 mg/kg b.w.) + MOR (100 mg/kg b.w.) simultaneously administered and IV, MOR (100 mg/kg b.w.), and all treatments lasted 14 days.

RESULTS

PCZ treatment displayed significant reduction in sperm number, sperm motility, percentage normal sperm cells, and daily sperm production rate. Meanwhile the activities of testicular enzymes: gamma-glutamyl transferase, acid phosphatase, and lactate dehydrogenase were significantly altered in the PCZ group compared to control. Furthermore, PCZ caused a significant reduction in levels of glutathione and ascorbic acid as well as activities superoxide dismutase, catalase, glutathione peroxidase, and glutathione S-transferase in the testes of PCZ-treated rats. A significant increase in testicular malondialdehyde level was also observed in the PCZ group. MOR treatment, however, significantly restored the altered sperm parameters and biochemical markers in the testis.

CONCLUSIONS

Our data suggest that MOR administration protected against PCZ-induced testicular and spermatotoxicity in rat, by improving testicular antioxidant system.

Current considerations in AYA Hodgkin lymphoma

Hodgkin lymphoma (HL) commonly occurs in adolescents and young adults (AYA), defined by the National Cancer Institute as people diagnosed with cancer between the ages of 15 and 39 years. Despite therapeutic advances, the AYA population has derived less incremental benefit compared to both paediatric and adult counterparts. Although the exact aetiology is unclear, contributing factors probably include differences in disease biology, delayed diagnosis, decreased participation in clinical trials and treatment adherence secondary to complex social factors. As such, while HL remains highly curable, there is not a clear consensus regarding the management of patients within this age range, specifically whether paediatric or adult regimens are preferred or how best to incorporate emerging therapeutic advancements. Ongoing clinical trials, as well as continued collaborative efforts are required to address the needs of this population, investigate the potential for unique biological factors and allow for optimization of treatment. Here we review current prognostic and treatment strategies for paediatric and adult patients with HL and highlight complexities around the management of this patient population.

[Andrology in oncological diseases]

In dermato-oncological treatment there are many gonadotoxic interventions. Alkylating and hormonally active substances as well as gonadal irradiation, in particular, are known to have a fertilization-limiting effect in men. Since 2017 certified skin cancer centers in Germany therefore have the task to implement counselling on preservation of fertility. This is supported by the S2k guidelines on preservation of fertility in oncological treatment. Because recommendation of the various interventions from the dermato-oncological guidelines are dependent on the stage, the authors advocate at least the question "Is the desire to have children of interest to you?" when patients reach the appropriate stage. Fertility protection of men via cryopreservation of ejaculates or testicular tissue is then a simple and safe option. The procedure is standardized and usually available. In addition, the possibility of cryopreservation of testicular tissue from prepubertal male children and infants is now available via the new Androprotect project. If signs of hypogonadism occur during therapy, a treatment can be considered by weighing up the effects of testosterone but in this case it is important to take the anabolic and immunomodulating effects into account.

Contemporarily Treated Patients With Hodgkin Lymphoma Have Childbearing Potential in Line With Matched Comparators

Purpose With excellent cure rates for young patients with Hodgkin lymphoma (HL), there is an increasing number of female survivors of HL interested in becoming pregnant. Here, we report childbearing among contemporarily treated HL survivors in comparison with the general population. Material and Methods Using Swedish registers, 449 women (ages 18 to 40 years) diagnosed with HL between 1992 and 2009 and in remission 9 months after diagnosis were identified. Patients were age- and calendar-year-matched to 2,210 population comparators. Rates of first postdiagnosis childbirth were calculated. Hazard ratios (HRs) with 95% CIs were estimated for different follow-up periods using Cox regression. Cumulative probabilities of first childbirth were calculated in the presence of the competing risk of death or relapse. Results Twenty-two percent of relapse-free patients with HL had a child during follow-up, and first childbirth rates increased over time, from 40.2 per 1,000 person-years (1992 to 1997) to 69.7 per 1,000 person-years (2004 to 2009). For comparators, childbirth rates remained stable (70.1 per 1,000 person-years). Patients diagnosed between 2004 and 2009 had a cumulative probability of childbirth similar to comparators. Three years or more after diagnosis, no differences in childbirth rates were observed between patients and comparators, regardless of stage or treatment. Patients who received six to eight courses of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone had a lower childbirth rate than comparators during the first 3 years (HR, 0.23; 95% CI, 0.06 to 0.94), as did patients who received six to eight courses of chemotherapy and radiotherapy (HR, 0.21; 95% CI, 0.07 to 0.65). Conclusion Childbearing potential among female survivors of HL has improved over time, and childbirth rates 3 years after diagnosis in contemporarily treated patients are, in the absence of relapse, similar to those in the general population, regardless of stage and treatment.

Adolescent and young adult Hodgkin lymphoma: Raising the bar through collaborative science and multidisciplinary care

Hodgkin lymphoma (HL) is one of the most common cancers in the adolescent and young adult (AYA) population (15-39 years). Despite continued improvements in HL outcomes, AYAs have not exhibited survival gains to the same extent as other age groups. At present, details about tumor biology, optimal therapeutic approaches, supportive care needs, and long-term toxicities in AYAs with HL remain understudied. Herein, we summarize the current state of the AYA population with HL, specifically focusing on how collaborations across the pediatric and medical oncology divide, coupled with multidisciplinary patient care, can further optimize outcomes for this group of patients.

Fertility preservation in Hodgkin's lymphoma patients that undergo targeted molecular therapies: an important step forward from the chemotherapy era

In total, 80%-90% of Hodgkin's lymphoma (HL) patients are curable with combination chemoradiotherapy. Due to improvements in therapeutic strategies, 50% of all relapsed/refractory patients may undergo complete clinical responses and have long-term survival. Treatment options for HL are effective, but may have a negative impact on post-chemotherapy fertility. Thus, cryopreservation of semen prior to treatment is recommended for male patients. For female patients, assisted reproductive techniques (ART) consult and fertility preservation should be offered as a therapeutical option. In the last years, new targeted molecules have been available for HL treatment. These new drugs showed a high rate of overall responses in the setting of heavily pretreated patients, most of them in relapse after autologous stem cell transplantation, a group previously considered very poor risk. Up to 50% of patients have a complete response and an improved overall survival. Future studies will address the usefulness of novel molecules as a frontline therapy. Considering the high response and survival rates with monoclonal antibody-based therapeutics, fertility has become a concerning issue for long-term HL survivors. As progress has been made regarding ART, with the rigorous steps planned for HL patients, more survivors will become parents.

PD-1, FOXP3, and CSF-1R expression in patients with Hodgkin lymphoma and their prognostic value

Despite advances in the treatment of Hodgkin lymphoma (HL), there is a need for development of reliable prognostic biomarkers and improved stratification of patients for effective therapeutic intervention. The immune microenvironment is the key to HL pathophysiology. The aim of this study was to identify expression of microenvironment-related biomarkers (PD-1, FOXP3, and CSF-1R) immunohistochemically and determine their association with clinicopathological features and prognosis in HL. We found that a high number of non-HRS cells expressing CSF-1R confers inferior overall survival (OS), which is associated with the presence of Epstein-Barr virus in neoplastic cells (P=0.009). Increased FOXP3 expression confered superior OS and progression-free survival (PFS). PD-1 expression had no significant association with OS and PFS. The combination of FOXP3 and PD-1 or CSF-1R may yield better prognostic stratification.

Adverse Effects of Vincristine Chemotherapy on Cell Changes in Seminiferous Tubules and Cetrorelix GnRH Antagonist Inhibitory Effects in Mice

The present study was designed to determine changes in spermatogenesis in adult mice after an intraperitoneal injection of vincristine. The effect of a GnRH antagonist synchronous to chemotherapy, which might protect spermatogenesis by halting cell division in spermatogenic cells, was also investigated.

Controversies over the use of GnRH agonists for reduction of chemotherapy-induced gonadotoxicity

The increase in cancer incidence in younger people and the significant improvement in long and permanent remission have brought concern about their reproductive future and quality of life. Up to two-thirds of adult female patients undergoing chemotherapy for malignancies eventually develop premature ovarian failure. This condition is related to many complaints including vasomotor symptoms, osteoporosis, increased risk of cardiovascular diseases, sexual dysfunction, and infertility. Therefore, protection against iatrogenic infertility and loss of endocrine ovarian function caused by chemotherapy is currently of high priority. Several options have been used for preserving ovarian function. Established methods include cryopreservation of embryos and/or ova, and ovarian transposition, while others such as ovarian tissue preservation are new, yet promising treatments for fertility preservation. The administration of gonadotropin releasing hormone (GnRH) agonistic analogs (GnRH-a) is still considered experimental. However, the recent evidence is strong to recommend the use of GnRH-a co-treatment during chemotherapy in young women with cancer to protect ovarian function, with promising results regarding fertility preservation. As the use of GnRH-a is non-invasive, highly available and without impact on cancer treatment outcomes, it should be offered to all young female cancer patients to preserve their ovarian function.

Female fertility preservation strategies: cryopreservation and ovarian tissue in vitro culture, current state of the art and future perspectives

In the present review, the main strategies of female fertility preservation are covered. Procedures of fertility preservation are necessary for women who suffer from diseases whose treatment requires the use of aggressive therapies, such as chemotherapy and radiotherapy. These kinds of therapy negatively influence the health of gametes and their progenitors. The most commonly used method of female fertility preservation is ovarian tissue cryopreservation, followed by the retransplantation of thawed tissue. Another approach to female fertility preservation that has been actively developed lately is the ovarian tissue in vitro culture. The principal methods, advantages and drawbacks of these two strategies are discussed in this article.

Documentation of Fertility Preservation Discussions for Young Adults With Cancer: Examining Compliance With Treatment Guidelines

BACKGROUND

Professional guidelines have been developed to promote discussion between providers and newly diagnosed young adults with cancer about the possibility of cancer treatment-related infertility, but previous research suggests many young adults fail to receive this information. The aim of this study was to examine rates of and factors predictive of oncologists' compliance with national guidelines for discussing potential treatment-related infertility with newly diagnosed young adults with cancer seen at an NCI-designated comprehensive cancer center.

METHODS

We reviewed data from the electronic medical record for new clinic encounters between medical oncologists and young adults with cancer (ages 18-39 years) from 2010 to 2012. Data from oncologist discussions of fertility preservation were abstracted, as were patient (age, sex, race, ethnicity, cancer type) and oncologist (gender, graduation year from fellowship) characteristics.

RESULTS

A total of 1,018 cases were reviewed, with 454 patients (mean, 31.5 years; 67.8% women) meeting inclusion criteria. Overall, 83% of patients were informed about potential treatment-related infertility, with patients with breast cancer (85% informed), Hodgkin lymphoma (95% informed), non-Hodgkin's lymphoma (94% informed), leukemia (88% informed), or testicular cancer (100% informed) more likely to be informed than those with other cancer types (60%-74% informed). There was a significant effect for patient sex (odds ratio, 3.57; CI, 1.33, 9.60; P=.012), with women being more likely to be informed than men.

CONCLUSIONS

Reported compliance with fertility preservation guidelines was greater than published rates. Higher compliance rates in female patients and in patients with cancers more common among young adults may reflect greater awareness of fertility-related concerns among these patients and their providers.

Outcomes of ovarian stimulation after treatment with chemotherapy

PURPOSE

Chemotherapeutic agents have a known gonadotoxic effect; however, it is difficult to predict the impact they may have on ovarian stimulation. The objective of this study was to evaluate response to ovarian stimulation in patients exposed to chemotherapy compared with patients who were chemotherapy-naïve.

METHODS

A retrospective cohort study of 130 patients with cancer or autoimmune disease was performed. Demographics, ovarian reserve, ovarian response and stimulation parameters, and oocyte data were compared between patients who were pre- and post-chemotherapy. Logistic regression modeling was performed to identify risk factors for cancellation and low oocyte yield, adjusting for confounders as appropriate.

RESULTS

Antral follicle count (AFC) was significantly lower in post-chemo patients (9 vs. 17, p < 0.001). Post-chemotherapy patients were more likely to be cancelled during stimulation (23 vs. 4 %, p = 0.003). Among those that went to retrieval, there was no difference in total number of oocytes (10 vs. 10, p = 0.31) or mature oocytes retrieved (8 vs. 8, p = 0.38), despite higher starting (300 vs. 450 IU, p < 0.001) and total gonadotropin (3075 vs. 4612.5 IU, p = 0.008) doses in post-chemotherapy patients. Low AFC (≤6) was associated with cycle cancellation (OR 7.7, 95 % CI 1.8-33.2) and low oocyte yield (<6) (OR 5.4, 95 % CI 1.6-17.7).

CONCLUSIONS

Patients post-chemotherapy have lower AFC compared with the chemotherapy-naïve and have higher cancellation rates. Among those who underwent oocyte retrieval, oocyte yield was similar in both groups. Low AFC was most strongly associated with cycle cancellation and oocyte yield. Post-chemotherapy patients had higher rates of cycle cancellation but did equally well as pre-chemotherapy patients if they reached retrieval.

Challenges and Potential for Ovarian Preservation with SERMs

Tamoxifen (TAM) is a selective estrogen receptor modulator with tissue-specific effects on estrogen signaling used predominantly for treatment and chemoprevention of breast cancers. Recent studies have shown that TAM prevents infertility and decreases follicular loss from common cancer chemotherapy and radiation therapy in preclinical models. Here we review current and novel uses of selective estrogen receptor modulator s and advantages and challenges for translation of TAM for human fertility preservation.
