Abstract
For patients with hematologic malignancies, novel therapeutic strategies offer the potential to achieve a complete clinical response and long-term survival. However, declining fertility has become a significant concern, impacting long-term quality of life. Conventional high-dose chemotherapy and radiotherapy are known to reduce fertility or cause sterility. Moreover, limited clinical data are available on the effects of newer therapies, such as targeted treatments and chimeric antigen receptor (CAR)-T cell therapy, on fertility. Additionally, there is no standard method for preserving fertility in these patients. Male patients can opt for sperm cryopreservation, whereas female patients may preserve fertility through embryo, oocyte, or ovarian tissue cryopreservation. However, preserving fertility in prepubescent patients remains particularly challenging. Therefore, hematologists must educate patients about the potential gonadal toxicity of cancer treatments and offer the most appropriate fertility preservation options.

Abstract
PURPOSE To provide updated fertility preservation (FP) recommendations for people with cancer. METHODS A multidisciplinary Expert Panel convened and updated the systematic review. RESULTS One hundred sixty-six studies comprise the evidence base. RECOMMENDATIONS People with cancer should be evaluated for and counseled about reproductive risks at diagnosis and during survivorship. Patients interested in or uncertain about FP should be referred to reproductive specialists. FP approaches should be discussed before cancer-directed therapy. Sperm cryopreservation should be offered to males before cancer-directed treatment, with testicular sperm extraction if unable to provide semen samples. Testicular tissue cryopreservation in prepubertal males is experimental and should be offered only in a clinical trial. Males should be advised of potentially higher genetic damage risks in sperm collected soon after cancer-directed therapy initiation and completion. For females, established FP methods should be offered, including embryo, oocyte, and ovarian tissue cryopreservation (OTC), ovarian transposition, and conservative gynecologic surgery. In vitro maturation of oocytes may be offered as an emerging method. Post-treatment FP may be offered to people who did not undergo pretreatment FP or cryopreserve enough oocytes or embryos. Gonadotropin-releasing hormone agonist (GnRHa) should not be used in place of established FP methods but may be offered as an adjunct to females with breast cancer. For patients with oncologic emergencies requiring urgent oncologic therapy, GnRHa may be offered for menstrual suppression. Established FP methods in children who have begun puberty should be offered with patient assent and parent/guardian consent. The only established method for prepubertal females is OTC. Oncology teams should ensure prompt access to a multidisciplinary FP team. Clinicians should advocate for comprehensive FP services coverage and help patients access benefits.Additional information is available at www.asco.org/survivorship-guidelines.

Ovarian stimulation response and fertility outcomes in patients with breast cancer across different stages, grades, and hormone receptor status for fertility preservation. J Formos Med Assoc 2025; 124:241-245. [PMID: 39214749 DOI: 10.1016/j.jfma.2024.08.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 08/19/2024] [Accepted: 08/23/2024] [Indexed: 09/04/2024] Open
Abstract
BACKGROUND This study aimed to explore the potential impact of stage, grade, and hormone receptor profile on ovarian stimulation response and fertility preservation outcomes. METHODS This retrospective cohort study evaluated data from breast cancer patients who underwent fertility preservation at a tertiary medical center between 2014 and 2022. The outcomes of women with low-stage cancer (stages I and II) were compared with those of women with high-stage disease (stages III and IV or lymph node metastasis). Similarly, we compared those with low-grade (grades 1 and 2) and high-grade (grade 3) malignancies. In addition, we compared different hormone statuses of breast cancer (1) estrogen receptor (ER) positive vs. ER-negative and (2) triple-negative breast cancer (TNBC) vs. non-TNBC. The primary outcome measured was the number of mature oocytes, while the secondary outcomes included the numbers of total oocytes retrieved, peak estradiol levels, and subsequent fertility preservation outcomes. RESULTS A total of 47 patients were included. Patients with high-grade tumors had a comparable number of mature oocytes (8 vs. 10, p = 0.08) compared to patients with low grade cancers. The stage-based analysis revealed a similar number of mature oocytes (8 vs. 10, p = 0.33) between high/low stage patients. In the hormone receptor-based analysis, no differences were seen in mature oocytes collected between the ER-positive/ER-negative group (9 vs. 9, p = 0.87) and the TNBC/non-TNBC group (11 vs. 9, p = 0.13). The utilization rate was 27.6% (13/47). CONCLUSION Our study showed similar ovarian stimulation response and fertility preservation outcomes among breast cancer patients with different prognostic factors.

Abstract
PURPOSE Fertility issues are of great concern for young women undergoing treatment for breast cancer (BC). Fertility preservation (FP) protocols using controlled ovarian stimulation (COS) with letrozole have been widely used with overall good results. However, letrozole cannot be used in every country in this context. This study aimed to assess the efficacy of tamoxifen for COS in women with early BC undergoing FP. METHODS This multicentric prospective study included patients aged 18-40, diagnosed with stage I, II and III invasive BC, undergoing tamoxifen-COS before adjuvant or neoadjuvant chemotherapy (NAC). The primary endpoint was the efficacy of tamoxifen-COS protocol evaluated by the number of oocytes collected and vitrified. Secondary endpoints included the time interval before chemotherapy, breast cancer (BC) recurrence rates, and reproductive outcomes. RESULTS Ninety-five patients were included between 2014 and 2017, aged 31.5 ± 4 years on average. 37.9 % received NAC and 62.1 % received adjuvant chemotherapy. FP procedure was successful in 89.5 % of the cycles. The mean number of collected and vitrified oocytes was 12.8 ± 7.9 and 9.8 ± 6.2, respectively. The mean duration of COS was 10.4 ± 1.9 days. Median time before chemotherapy initiation was 3.6 weeks (IQR 3.1; 4.1) for women receiving NAC. Five-year relapse-free and overall survival rates were in-line with those expected in this population. Twenty-one women had spontaneous full-term pregnancies, while 5 underwent IVF cycles with frozen-thawed oocytes, without pregnancy. CONCLUSION Tamoxifen-COS protocols appear to be feasible before adjuvant or NAC treatment in young BC patients and efficient in terms of oocyte yield.

Abstract
PURPOSE OF REVIEW In this Perspective we share the personal story of a 33-year-old patient diagnosed with metastatic breast cancer and her journey through fertility preservation, surrogacy, and eventually motherhood, highlighting misconceptions about fertility preservation in this population. RECENT FINDINGS There are nearly 1 million women under the age of 50 diagnosed and living with cancer in the USA. These patients are met with life-altering decisions, including those that may limit their reproductive ability. While there have been tremendous advances and advocacy in the field of oncofertility, there has been limited focus on patients with advanced stage or metastatic cancer. We describe five key misconceptions surrounding fertility preservation in patients with advanced stage cancer, offering a review of the literature and our approach to challenging topics like desiring fertility preservation in the face of Stage 4 disease, the safety and timing of ovarian stimulation during cancer treatment, and passing away following fertility preservation. We review the importance of assessing perceptions of fertility preservation in patients with metastatic cancer and highlight the lack of research in this area as a call to action.

Abstract
RESEARCH QUESTION Is ovarian stimulation with levonorgestrel intrauterine system (LNG-IUS) in situ and co-treatment with letrozole safe and effective in patients undergoing fertility-sparing combined treatment for atypical endometrial hyperplasia (AEH) or early endometrial cancer limited to the endometrium? DESIGN Retrospective case-control study recruiting women who had undergone fertility-sparing 'combined' treatment and ovarian stimulation with letrozole and LNG-IUS in situ. The 'three steps' hysteroscopic technique was used. Once complete response was achieved, the ovaries were stimulated, and mature oocytes cryopreserved. The LNG-IUS was removed, and embryos transferred. A comparative analysis was conducted between the two control groups of the initial outcomes of ART (number of oocytes and MII oocytes retrieved): healthy infertile women undergoing ovarian stimulation for IVF/ICSI (control group A); and patients diagnosed with breast cancer who underwent ovarian stimulation with letrozole (control group B). RESULTS Of the 75 patients analysed, 15 underwent oocyte cryopreservation after achieving a complete response to fertility-sparing treatment (study group); 30 patients in control group A and B, respectively. No statistically significant differences were observed in retrieved oocytes and mature oocytes between the study and control groups. In the nine patients who underwent embryo transfer, clinical pregnancy (55.6%), cumulative live birth (44.4%) and miscarriage (20%) rates were reported. In three patients with AEH, recurrence occurred (12%) at 3, 6 and 16 months after removing the LNG-IUS to attempt embryo transfer, respectively. CONCLUSION Fertility-sparing hysteroscopic combined treatment and subsequent ovarian stimulation with letrozole and LNG-IUS in situ could be suggested to women with AEH or early endometrial cancer who ask for future fertility preservation.

Abstract
PURPOSE To clarify the reproductive outcomes of fertility preservation (FP) treatment. METHODS We conducted a mailed-in questionnaire survey at institutions certified by the Japan Society of Obstetrics and Gynecology to investigate the number of oocyte cryopreservations (OC) and ovarian tissue cryopreservations (OTC) performed from December 2016 to the end of 2020. And, we conducted a detailed investigation of cases in which frozen specimens were used during the investigation period, and made historical comparisons with previous nationwide studies. RESULTS Responses were received from 114 out of 150 facilities (response rate: 76.0%) for OC and 43 out of 51 for OTC (response rate: 84.3%). Breast cancer was the most common disease among patients whose FP specimens were used. During the study period, 1237 OCs and 198 OTCs were performed. In addition, 57 cycles of embryo transfer (ET) using cryopreserved oocytes and 12 cases of ovarian tissue transplantation (OTT) were performed. The mean age of patients who underwent ET using cryopreserved oocytes was 34.8 (±5.8) years, with a median age of 36 years. The pregnancy rate per ET using cryopreserved oocytes was 26.3% and the live birth rate (LBR) was 17.5%. Further, the LBR per patient was 43.3%, and the pregnancy rate following OTTs was 33.3%. Also, controlled ovarian stimulation using the random start method or the combination of aromatase inhibitors had no effect on pregnancy outcome. CONCLUSION Implementation of both OCs and OTCs have markedly increased over time in Japan, with comparable reproductive outcomes as other reports.

Abstract
Purpose To verify the effectiveness of embryo transfer (ET) using cryopreserved embryo as fertility preservation (FP). Methods This study was a questionnaire survey. The total number of embryo cryopreservation (EC) was investigated between 2014 and 2020. And for patients who underwent ET among study period, details of EC, outcome of ET, number of live births, and mortality were investigated. Results Of the 150 facilities, 114 responded (76.0%). A total of 1420 EC were performed during the study period; and ET was performed for 417 patients. Breast cancer was the most common primary disease. A total of 199 live births (including prospective) were obtained by ET; 1.7 EC and 2.2 ET were performed per patient, and live birth rate was 21.4% per ET (28.1% on 35-37-year-old patients). The number of EC and ET increased with age. The final birth rate, including pregnancies other than FP, was 51.8%. Ovarian stimulation with aromatase inhibitors was commonly used, although with no effect on live birth rates. Random start stimulation was also common, experienced by 36.3% of breast cancer patients. Conclusion Reproductive outcomes of ETs following EC as FP are acceptable. This research project was registered in the University Hospital Medical Information Network (UMIN000043664).

Abstract
Purpose Tamoxifen is used for the suppression of estrogen-sensitive tumor recurrence in oocyte retrieval cycles. This meta-analysis aimed to evaluate the quality of controlled ovarian stimulation (COS) with co-administration of gonadotropins and tamoxifen (COS with tamoxifen). Methods PubMed, Embase, and Cochrane Library were searched for articles on October 30, 2022. The authors included studies comparing COS with tamoxifen and COS with gonadotropins and letrozole (COS with letrozole) or gonadotropin only (COS with gonadotropin only) for fertility preservation in patients with breast cancer. The main outcome measures were the COS quality, total number of retrieved oocytes (TOR), total number of mature oocytes (TMO), and peak estradiol levels (PEL). Results Four studies (348 patients, two randomized controlled trials, and two cohort studies) were included in our meta-analysis. There was no significant difference in TOR (95% CI, [-3.84, 2.90]) and TMO (95% CI, [-2.20, 2.64]) between COS with tamoxifen and COS with letrozole. There was also no difference in TOR (95% CI, [-6.14, 1.86]) between COS with tamoxifen and COS with gonadotropin only. Statistically significant decrease was observed in PEL during COS with letrozole compared with tamoxifen (95% CI, [1414.4, 4953.7]). Conclusions The quality did not differ between COS with tamoxifen and COS with letrozole or gonadotropin only.

J Assist Reprod Genet 2022; 39:2617-2624. [PMID: 36192617 PMCID: PMC9723077 DOI: 10.1007/s10815-022-02626-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Accepted: 09/21/2022] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND In this secondary analysis of the TAmoxifen or Letrozole in Estrogen Sensitive tumors (TALES) trial, we aimed to investigate if concurrent administration of letrozole vs. tamoxifen vs. no added treatment affects hormonal composition and size of stimulated ovarian follicles. METHODS TALES is a randomized controlled trial of IVF stimulation for estrogen receptor (ER)-positive breast cancer patients stimulated with gonadotropins and administered concurrent tamoxifen 20 mg or letrozole 5 mg. We analyzed estradiol (E2), testosterone (T), progesterone (P4), follicle stimulating hormone (FSH), luteinizing hormone (LH), and anti-Mullerian hormone (AMH). We used ANOVA/Kruskal-Wallis, logistic, and linear regression models to examine differences in follicular hormone levels, size, and mature oocyte yield between trial arm. RESULTS We included data from total 246 follicles (94 letrozole, 82 tamoxifen, and 70 control) from 123 unique participants. E2 was lower (letrozole 187.4, tamoxifen 1026.0, control 821.5 ng/mL, p < 0.01) and T was higher (letrozole 2489, tamoxifen 571, and control 504 ng/mL, p < 0.03) in the letrozole group compared to tamoxifen and control groups, while other hormone levels and follicle size were similar across groups. There were no significant differences in hormone concentrations within the follicle between tamoxifen and control arms. On multivariate logistic regression, there was no significant association of mature oocyte yield by follicle size, hormone levels, or trial arm. CONCLUSIONS Concurrent administration of letrozole with gonadotropins affects follicular E2 and T concentrations compared to tamoxifen/control. Tamoxifen was not associated with any differences in hormone concentrations within the follicle. Mature oocyte yield was similar across groups.

Abstract
STUDY QUESTION Does ovarian stimulation with the addition of tamoxifen or letrozole affect the number of cumulus-oocyte complexes (COCs) retrieved compared to standard ovarian stimulation in women with breast cancer who undergo fertility preservation? SUMMARY ANSWER Alternative ovarian stimulation protocols with tamoxifen or letrozole did not affect the number of COCs retrieved at follicle aspiration in women with breast cancer. WHAT IS KNOWN ALREADY Alternative ovarian stimulation protocols have been introduced for women with breast cancer who opt for fertility preservation by means of banking of oocytes or embryos. How these ovarian stimulation protocols compare to standard ovarian stimulation in terms of COC yield is unknown. STUDY DESIGN, SIZE, DURATION This multicentre, open-label randomized controlled superiority trial was carried out in 10 hospitals in the Netherlands and 1 hospital in Belgium between January 2014 and December 2018. We randomly assigned women with breast cancer, aged 18–43 years, who opted for banking of oocytes or embryos to one of three study arms; ovarian stimulation plus tamoxifen, ovarian stimulation plus letrozole or standard ovarian stimulation. Standard ovarian stimulation included GnRH antagonist, recombinant FSH and GnRH agonist trigger. Randomization was performed with a web-based system in a 1:1:1 ratio, stratified for oral contraception usage at start of ovarian stimulation, positive estrogen receptor (ER) status and positive lymph nodes. Patients and caregivers were not blinded to the assigned treatment. The primary outcome was number of COCs retrieved at follicle aspiration. PARTICIPANTS/MATERIALS, SETTING, METHODS During the study period, 162 women were randomly assigned to one of three interventions. Fifty-four underwent ovarian stimulation plus tamoxifen, 53 ovarian stimulation plus letrozole and 55 standard ovarian stimulation. Analysis was according to intention-to-treat principle. MAIN RESULTS AND THE ROLE OF CHANCE No differences among groups were observed in the mean (±SD) number of COCs retrieved: 12.5 (10.4) after ovarian stimulation plus tamoxifen, 14.2 (9.4) after ovarian stimulation plus letrozole and 13.6 (11.6) after standard ovarian stimulation (mean difference −1.13, 95% CI −5.70 to 3.43 for tamoxifen versus standard ovarian stimulation and 0.58, 95% CI −4.03 to 5.20 for letrozole versus standard ovarian stimulation). After adjusting for oral contraception usage at the start of ovarian stimulation, positive ER status and positive lymph nodes, the mean difference was −1.11 (95% CI −5.58 to 3.35) after ovarian stimulation plus tamoxifen versus standard ovarian stimulation and 0.30 (95% CI −4.19 to 4.78) after ovarian stimulation plus letrozole versus standard ovarian stimulation. There were also no differences in the number of oocytes or embryos banked. There was one serious adverse event after standard ovarian stimulation: one woman was admitted to the hospital because of ovarian hyperstimulation syndrome. LIMITATIONS, REASONS FOR CAUTION The available literature on which we based our hypothesis, power analysis and sample size calculation was scarce and studies were of low quality. Our study did not have sufficient power to perform subgroup analysis on follicular, luteal or random start of ovarian stimulation. WIDER IMPLICATIONS OF THE FINDINGS Our study showed that adding tamoxifen or letrozole to a standard ovarian stimulation protocol in women with breast cancer does not impact the effectiveness of fertility preservation and paves the way for high-quality long-term follow-up on breast cancer treatment outcomes and women’s future pregnancy outcomes. Our study also highlights the need for high-quality studies for all women opting for fertility preservation, as alternative ovarian stimulation protocols have been introduced to clinical practice without proper evidence. STUDY FUNDING/COMPETING INTEREST(S) The study was supported by a grant (2011.WO23.C129) of ‘Stichting Pink Ribbon’, a breast cancer fundraising charity organization in the Netherlands.

COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:1979254. [PMID: 35464999 PMCID: PMC9023147 DOI: 10.1155/2022/1979254] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Revised: 03/01/2022] [Accepted: 03/12/2022] [Indexed: 11/23/2022]
Abstract
Objective To explore the efficacy, safety, and patient prognosis of letrozole (LTZ) alone or in sequence with tamoxifen (TAM) for the treatment of breast carcinoma (BC). Methods In this retrospective study, 150 patients with BC who received treatment in the First People's Hospital of Ningyang County between January 2012 and January 2017 were selected. According to different treatment methods, 99 cases receiving sequential therapy with TAM and LTZ were included in the research group, and the remaining 51 patients receiving LTZ monotherapy were selected as the control group. The efficacy, safety, survival rate, recurrence rate, and blood lipid indices (total cholesterol, TC; triglyceride, TG; high-density lipoprotein cholesterol, HDL-C; and low-density lipoprotein cholesterol, LDL-C) of the two groups were observed and compared. Results The overall response rate of the research group was statistically higher than that of the control group, and the incidence of adverse reactions was significantly lower. No evident difference was observed in 1-, 3-, or 5-year survival rates between the two groups, while the 3-5-year recurrence rate was obviously lower, and the improvement of blood lipid indices was significantly better in the research group compared with the control group. Conclusion LTZ alone or in sequence with TAM is effective and safe for the treatment of BC, which can significantly improve the prognosis and blood lipid indices of BC patients.
