ABSTRACT

BACKGROUND: Ribociclib has been shown to have a significant overall survival benefit in patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer. Whether this benefit in advanced breast cancer extends to early breast cancer is unclear. METHODS: In this international, open-label, randomized, phase 3 trial, we randomly assigned patients with HR-positive, HER2-negative early breast cancer in a 1:1 ratio to receive ribociclib (at a dose of 400 mg per day for 3 weeks, followed by 1 week off, for 3 years) plus a nonsteroidal aromatase inhibitor (NSAI; letrozole at a dose of 2.5 mg per day or anastrozole at a dose of 1 mg per day for ≥5 years) or an NSAI alone. Premenopausal women and men also received goserelin every 28 days. Eligible patients had anatomical stage II or III breast cancer. Here we report the results of a prespecified interim analysis of invasive disease-free survival, the primary end point; other efficacy and safety results are also reported. Invasive disease-free survival was evaluated with the use of the Kaplan-Meier method. The statistical comparison was made with the use of a stratified log-rank test, with a protocol-specified stopping boundary of a one-sided P-value threshold of 0.0128 for superior efficacy. RESULTS: As of the data-cutoff date for this prespecified interim analysis (January 11, 2023), a total of 426 patients had had invasive disease, recurrence, or death. A significant invasive disease-free survival benefit was seen with ribociclib plus an NSAI as compared with an NSAI alone. At 3 years, invasive disease-free survival was 90.4% with ribociclib plus an NSAI and 87.1% with an NSAI alone (hazard ratio for invasive disease, recurrence, or death, 0.75; 95% confidence interval, 0.62 to 0.91; P = 0.003). Secondary end points - distant disease-free survival and recurrence-free survival - also favored ribociclib plus an NSAI. The 3-year regimen of ribociclib at a 400-mg starting dose plus an NSAI was not associated with any new safety signals. CONCLUSIONS: Ribociclib plus an NSAI significantly improved invasive disease-free survival among patients with HR-positive, HER2-negative stage II or III early breast cancer.

ABSTRACT

PURPOSE: This study evaluated the effectiveness of ovarian function suppression (OFS) of various gonadotropin-releasing hormone agonists (GnRHa) combined with aromatase inhibitors (AI) in premenopausal patients with hormone receptor-positive (HR-positive) breast cancer. Potential risk factors associated with insufficient OFS were analyzed. PATIENTS AND METHODS: Premenopausal HR-positive breast cancer patients who had received AI with GnRHa were studied retrospectively. Patients were divided into different groups according to monthly or trimonthly GnRHa schedules they received, and the effectiveness of OFS was compared between groups. Insufficient OFS was defined as at least one instance of estradiol ≥ 30 pg/ml. Patient data was gathered from medical records for this comparison. RESULTS: Of the 264 patients enrolled in this study, 117 were administered 3.6 mg of goserelin monthly (goserelin 1 M group), 63 received 3.75 mg of leuprorelin monthly (leuprorelin 1 M group) and 84 were given 11.25 mg of leuprorelin every three months (leuprorelin 3 M group). Overall, 7.20% experienced insufficient OFS. The incidence rates in the three GnRHa depot groups were 7.69%, 6.35%, and 7.14%, respectively, without a significant statistical difference (P = 0.900). Notably, younger patients exhibited a higher likelihood of insufficient OFS [OR = 0.900, 95%CI (0.824-0.982), P = 0.018]. CONCLUSION: Insufficient OFS remains a concern during GnRHa and AI treatment. The effectiveness of the three GnRHa depots commonly used in China seems comparable. Younger patients face a heightened risk of insufficient OFS.

ABSTRACT

INTRODUCTION: Neoadjuvant endocrine therapy (NET) has demonstrated efficacy in post-menopausal patients with hormone-responsive breast cancer. This trial was designed to compare the efficacy of neoadjuvant chemotherapy (NCT) with NET in pre-menopausal breast cancer. PATIENTS AND METHODS: In this prospective, randomised, phase III study, oestrogen receptor (ER)-positive, HER2-negative, and lymph node-positive pre-menopausal breast cancer patients were recruited from 7 hospitals in South Korea. Enrolled patients were randomly assigned (1:1) to receive 24 weeks of either NCT or NET with goserelin and tamoxifen. The primary purpose was to evaluate the non-inferiority of NET compared to NCT using clinical response, assessed by MRI. Besides, pathological complete response rate (pCR), changes in Ki-67 expression, breast conservation surgery (BCS) rate, and quality of life were included as secondary endpoints. RESULTS: A total of 187 patients were assigned to receive NCT (n = 95) or NET (n = 92), and 87 patients in each group completed treatments. More NCT patients had complete response or partial response than NET patients using MRI (NCT 83.7% vs. NET 52.9%, 95% CI 17.6-44.0, p < 0.001) and callipers (NCT 83.9% vs. NET 71.3%, 95% CI 0.4-24.9, p = 0.046). Three NCT patients (3.4%) and one NET patient (1.2%) showed pCR (p < 0.005). No difference existed in the conversion rate of BCS (13.8% for NCT vs. 11.5% for NET, p = 0.531) and Ki-67 change (p = 0.114) between the two groups. Nineteen NCT patients had treatment-related grade 3 or worse events compared with none in the NET group. CONCLUSIONS: Better clinical responses were observed in pre-menopausal patients after 24 weeks of NCT compared to those observed after NET. TRIAL REGISTRATION: Clinicaltrials.gov, NCT01622361.

ABSTRACT

BACKGROUND: Immunosuppressive cytokines have the potential to promote prostate cancer progression. Assessing their longitudinal changes may implicate mechanisms of progression, treatment resistance, and suggest new therapeutic targets. METHODS: Thirty-seven men with biochemically recurrent (BCR) prostate cancer who received 6 months of androgen deprivation therapy (ADT) and were monitored until the time to prostate-specific antigen progression (TTPP) were identified from a completed phase III trial (NCT00020085). Serum samples were archived at baseline, 3 months after ADT, and at TTPP. Cytokine concentrations were quantified using a 36-parameter electrochemiluminescence assay. The Wilcoxon signed-rank sum test was used to compare observations between time points. Kaplan-Meier analysis was used to calculate TTPP dichotomized by cytokine values above or below the median. Pearson's rank correlation coefficient was used to compare continuous variables. RESULTS: Median TTPP was 399 days (range, 114-1641). Median prostate-specific antigen (PSA) at baseline and progression were 8.5 and 5.3 ng/mL, respectively. Twenty-three patients (62%) achieved undetectable PSA with ADT. Castrate levels of testosterone (<50 ng/dL) after 3 months of ADT occurred in 35 patients (95%). TNF-α (P = .002), IL-23 (P = .002), and CXCL10 (P = .001) significantly increased from baseline to post ADT. Certain cytokines correlated longitudinally: TNF-α correlated with IL-23 (r = .72; P < .001) and IL-8 (r = .59; P < .001) from baseline to post ADT and to PSA progression. Neutrophil-to-lymphocyte ratio correlated with IL-27 (r = .57; P < .001) and MIP-3α (r = .56; P < .001). Patients with a detectable PSA after ADT had elevated levels of IL-6 (P = .049) and IL-8 (P = .013) at PSA progression as compared with those with an undetectable PSA. There was a trend toward shorter TTPP in patients with TNF-α levels above the median (P = .042). CONCLUSIONS: Several innate cytokines were associated with biochemically recurrent prostate cancer.

ABSTRACT

We report the failure to achieve castrate level of serum testosterone during luteinizing hormone-releasing hormone agonist therapy in a patient with prostate cancer. A 76-year-old man was admitted to our hospital for evaluation of an elevated serum prostate specific antigen (PSA) level (191.10 ng/ml) in August 2011. He was diagnosed with T3aN0M1b prostate adenocarcinoma. A combined androgen blockade using luteinizing hormone-releasing hormone agonist (the 1-month depot of leuprorelin acetate) and antiandrogen was administered. Due to liver dysfunction, antiandrogens, both bicalutamide and flutamide, were stopped. The 1-month depot was switched to the 3-month depot in May 2013, but the patient complained of induration and abscess at the infection site. Leuprorelin acetate was replaced by goserelin acetate. Because no adverse event appeared after injection of the 1-month depot of goserelin acetate, the 3-month depot was administered in October 2013. The PSA level increased gradually, and the testosterone level was greater than 50 ng/dl, that is, above castrate range. The 3-month depot of both leuprorelin acetate and goserelin acetate was not effective for this patient. For this reason, the 1-month depot of leuprorelin acetate was started resulting in a rapid decrease in PSA and testosterone levels. Thereafter, androgen depriving therapy could be continued. Androgen deprivation therapy is the standard treatment for patients with advanced prostate cancer and luteinizing hormone-releasing hormone aims to suppress serum testosterone to castrate range. We recommend assessing the serum testosterone levels during luteinizing hormone-releasing hormone agonist therapy for monitoring treatment efficacy and verifying progression when the PSA level increases.

ABSTRACT

BACKGROUND: Uterine fibroids can cause heavy menstrual bleeding. Medical treatments are considered to preserve fertility. It is unclear whether progestogens or progestogen-releasing intrauterine systems can reduce fibroid-related symptoms. This is the first update of a Cochrane Review published in 2013. OBJECTIVES: To determine the effectiveness of progestogens or progestogen-releasing intrauterine systems in treating premenopausal women with uterine fibroids. SEARCH METHODS: We searched the Cochrane Gynaecology and Fertility Group Specialised Register, CENTRAL, MEDLINE, Embase, and PsycINFO databases to July 2020. We also searched trials registers for ongoing and registered trials, and checked references of relevant trials. SELECTION CRITERIA: All identified published or unpublished randomised controlled trials (RCTs) assessing the effect of progestogens or progestogen-releasing intrauterine systems in treating premenopausal women with uterine fibroids. DATA COLLECTION AND ANALYSIS: Two authors independently extracted data, assessed risk of bias, and assessed the quality of the evidence using the GRADE approach. MAIN RESULTS: This updated review included four studies with 221 women with uterine fibroids. The evidence was very low quality, downgraded for serious risk of bias, due to poor reporting of study methods, and serious imprecision. Levonorgestrel-releasing intrauterine device (LNG-IUS) versus hysterectomy There was no information on the outcomes of interest, including adverse events. LNG-IUS versus low dose combined oral contraceptive (COC) At 12 months, we are uncertain whether LNG-IUS reduced the percentage of abnormal uterine bleeding, measured with the alkaline hematin test (mean difference (MD) 77.50%, 95% confidence interval (CI) 70.44 to 84.56; 1 RCT, 44 women; very low-quality evidence), or the pictorial blood assessment chart (PBAC; MD 34.50%, 95% CI 11.59 to 57.41; 1 RCT, 44 women; very low-quality evidence); increased haemoglobin levels (MD 1.50 g/dL, 95% CI 0.85 to 2.15; 1 RCT, 44 women; very low-quality evidence), or reduced fibroid size more than COC (MD 1.90%, 95% CI -12.24 to 16.04; 1 RCT, 44 women; very low-quality evidence). The study did not measure adverse events. LNG-IUS versus oral progestogen (norethisterone acetate (NETA)) Compared to NETA, we are uncertain whether LNG-IUS reduced abnormal uterine bleeding more from baseline to six months (visual bleeding score; MD 23.75 points, 95% CI 1.26 to 46.24; 1 RCT, 45 women; very low-quality evidence); increased the percentage of change in haemoglobin from baseline to three months (MD 4.53%, 95% CI 1.46 to 7.60; 1 RCT, 48 women; very low-quality evidence), or from baseline to six months (MD 10.14%, 95% CI 5.57 to 14.71; 1 RCT, 45 women; very low-quality evidence). The study did not measure fibroid size. Spotting (adverse event) was more likely to be reported by women with the LNG-IUS (64.3%) than by those taking NETA (30%; 1 RCT, 45 women; very low-quality evidence). Oral progestogen (dienogest, desogestrel) versus goserelin acetate Compared to goserelin acetate, we are uncertain whether abnormal uterine bleeding was reduced at 12 weeks with dienogest (PBAC; MD 216.00 points, 95% CI 149.35 to 282.65; 1 RCT, 14 women; very low-quality evidence) or desogestrel (PBAC; MD 78.00 points, 95% CI 28.94 to 127.06; 1 RCT, 16 women; very low-quality evidence). Vasomotor symptoms (adverse events, e.g. hot flashes) are only associated with goserelin acetate (55%), not with dienogest (1 RCT, 14 women; very low-quality evidence) or with desogestrel (1 RCT, 16 women; very low-quality evidence). The study did not report fibroid size. AUTHORS' CONCLUSIONS: Because of very low-quality evidence, we are uncertain whether the LNG-IUS reduces abnormal uterine bleeding or increases haemoglobin levels in premenopausal women with uterine fibroids, compared to COC or norethisterone acetate. There was insufficient evidence to determine whether the LNG-IUS reduces the size of uterine fibroids compared to COC. We are uncertain whether oral progestogens reduce abnormal uterine bleeding as effectively as goserelin acetate, but women reported fewer adverse events, such as hot flashes.

ABSTRACT

This study elucidated the degree of adenomyosis recurrence following gonadotropin-releasing hormone agonist (GnRHa) discontinuation and dienogest efficiency for recurrent adenomyosis. This retrospective cohort study included 30 patients, divided into a group of patients whose progress was observed without providing additional therapy following GnRHa administration for six months (Group G) and a group of patients administered dienogest for six months following six months of GnRHa administration (Group D). Menorrhagia, dysmenorrhea, chronic pelvic pain, abdominal fullness, and uterine volume were recorded prior to treatment, six months after the start of therapy (6 M), and 12 months after the start of therapy (12 M). In Group G (n = 15), although all subjective symptoms disappeared at 6 M, nearly all symptoms recurred at 12 M. Uterine volume significantly decreased from 341.0 cm3 to 156.0 cm3 at 6 M (p = .001) and significantly increased again to 282.3 cm3 at 12 M (p = .003). In Group D (n = 15), all subjective symptoms disappeared at 6 M, and only abdominal fullness returned in a significant number of patients (5 of 5; p = .021) at 12 M. Uterine volume decreased significantly at 6 M (p = .003) and significantly increased again from 162.5 cm3 to 205.6 cm3 at 12 M (p = .006). Subjective symptoms, except for abdominal fullness, did not recur when dienogest was administered after GnRHa.

ABSTRACT

In this study, we aimed to compare changes in cavernosal tissues in rats with antiandrogen treatment and orchiectomy. A total of 42 Wistar albino rats were divided into four groups. Group I, control group, Group II, LH-RH was given for 1 month, Group III-LH-RH + Bicalutamide was given for 1 month, and Group IV was defined as orchiectomy and followed up for 1 month. Measurements of intracavernosal pressure with different electrical stimuli and pathological findings of smooth muscle collagen in cavernosal tissues were examined. While the cavernosal pressure response in all the different electrical stimuli given in the control group and in all other groups was significantly lower than that in the other groups, it was statistically significant at 7.5 and 10 V (p = .005, p < 0001). According to the pathologic evaluation, the density of tissue collagen increased significantly in the other groups according to the control group. In groups 3 and 4, the density of 4+ collagen was found to be increased according to Groups 1 and 2. In the LH-RH alone group, it appears that there are no 4+ colloid density and less damage. According to these findings, the negative effect of LH-RH treatment on cavernosal tissues appears to be less.

ABSTRACT

BACKGROUND: Testosterone suppression is the standard treatment for advanced prostate cancer, and it is associated with side-effects that impair patients' quality of life, like sexual dysfunction, osteoporosis, weight gain, and increased cardiovascular risk. We hypothesized that abiraterone acetate with prednisone (AAP) and apalutamide, alone or in combination, can be an effective hormonal therapy also possibly decreasing castration-associated side effects. METHODS: Phase II, open-label, randomized, efficacy trial of abiraterone acetate plus prednisone (AAP) and Androgen Deprivation Therapy (ADT) versus apalutamide versus the combination of AAP (without ADT) and apalutamide. Key eligibility criteria are confirmed prostate adenocarcinoma; biochemical relapse after definitive treatment (PSA ≥ 4 ng/ml and doubling time less than 10 months, or PSA ≥ 20 ng/ml); newly diagnosed locally advanced or metastatic prostate cancer; asymptomatic to moderately symptomatic regarding bone symptoms. Patients with other histology besides adenocarcinoma or previous use of hormonal therapy or chemotherapy were excluded. DISCUSSION: There is an urgent need to study and validate regimens such as new hormonal agents that may add benefit to castration with an acceptable safety profile. We aim to evaluate if apalutamide in monotherapy or in combination with AAP is an effective and safety hormonal treatment that can spare patients of androgen deprivation therapy. TRIAL REGISTRATION: This trial was registered in ClinicalTrials.gov on October 16, 2017, under Identifier: NCT02867020.

ABSTRACT

This study aimed to prepare and optimize goserelin acetate (GOS) loaded hydrogel poly(d,l-lactic acid-co-glycolic acid) (PLGA) microsphere that is suitable for long-acting clinical treatment, investigate its structure, and regulate the initial release manner. Here, the PLGA microsphere containing Poloxamer hydrogel loaded with ∼15% (w/w) GOS was prepared by double-emulsion-solvent evaporation method and evaluated in terms of microscopic structure, physicochemical properties, and release manner in vitro and in vivo. Raman volume imaging and scanning electron microscopy studies revealed a core-shell Di-Depot structure of the microsphere, in which multi-GOS-loaded hydrogel depots were distributed in the core region. Under the interaction of hydrogel and PLGA depots, high encapsulation efficiency (94.16%) and low burst release (less than 2%) were achieved, along with the accompanying prolonged administration interval (49 days); an enhanced relative bioavailability 9.36-fold higher than that of Zoladex implant was also observed. Also, by addition of 1-5% acetic acid, the lag time was shortened to 6 days. The strategy for regulating the initial release provides new insights for manipulating the release behavior of the PLGA microspheres. The desirable property of the Poloxamer hydrogel PLGA microsphere indicated its promising application in controlled release drug delivery system.

ABSTRACT

BACKGROUND: The NRG/RTOG 9413 study showed that whole pelvic radiotherapy (WPRT) plus neoadjuvant hormonal therapy (NHT) improved progression-free survival in patients with intermediate-risk or high-risk localised prostate cancer compared with prostate only radiotherapy (PORT) plus NHT, WPRT plus adjuvant hormonal therapy (AHT), and PORT plus AHT. We provide a long-term update after 10 years of follow-up of the primary endpoint (progression-free survival) and report on the late toxicities of treatment. METHODS: The trial was designed as a 2 × 2 factorial study with hormonal sequencing as one stratification factor and radiation field as the other factor and tested whether NHT improved progression-free survival versus AHT, and NHT plus WPRT versus NHT plus PORT. Eligible patients had histologically confirmed, clinically localised adenocarcinoma of the prostate, an estimated risk of lymph node involvement of more than 15% and a Karnofsky performance status of more than 70, with no age limitations. Patients were randomly assigned (1:1:1:1) by permuted block randomisation to receive either NHT 2 months before and during WPRT followed by a prostate boost to 70 Gy (NHT plus WPRT group), NHT 2 months before and during PORT to 70 Gy (NHT plus PORT group), WPRT followed by 4 months of AHT (WPRT plus AHT group), or PORT followed by 4 months of AHT (PORT plus AHT group). Hormonal therapy was combined androgen suppression, consisting of goserelin acetate 3·6 mg once a month subcutaneously or leuprolide acetate 7·5 mg once a month intramuscularly, and flutamide 250 mg twice a day orally for 4 months. Randomisation was stratified by T stage, Gleason Score, and prostate-specific antigen concentration. NHT was given 2 months before radiotherapy and was continued until radiotherapy completion; AHT was given at the completion of radiotherapy for 4 months. The primary endpoint progression-free survival was analysed by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00769548. The trial has been terminated to additional follow-up collection and this is the final analysis for this trial. FINDINGS: Between April 1, 1995, and June 1, 1999, 1322 patients were enrolled from 53 centres and randomly assigned to the four treatment groups. With a median follow-up of 8·8 years (IQR 5·07-13·84) for all patients and 14·8 years (7·18-17·4) for living patients (n=346), progression-free survival across all timepoints continued to differ significantly across the four treatment groups (p=0·002). The 10-year estimates of progression-free survival were 28·4% (95% CI 23·3-33·6) in the NHT plus WPRT group, 23·5% (18·7-28·3) in the NHT plus PORT group, 19·4% (14·9-24·0) in the WPRT plus AHT group, and 30·2% (25·0-35·4) in the PORT plus AHT group. Bladder toxicity was the most common grade 3 or worse late toxicity, affecting 18 (6%) of 316 patients in the NHT plus WPRT group, 17 (5%) of 313 in the NHT plus PORT group, 22 (7%) of 317 in the WPRT plus AHT group, and 14 (4%) of 315 in the PORT plus AHT group. Late grade 3 or worse gastrointestinal adverse events occurred in 22 (7%) of 316 patients in the NHT plus WPRT group, five (2%) of 313 in the NHT plus PORT group, ten (3%) of 317 in the WPRT plus AHT group, and seven (2%) of 315 in the PORT plus AHT group. INTERPRETATION: In this cohort of patients with intermediate-risk and high-risk localised prostate cancer, NHT plus WPRT improved progression-free survival compared with NHT plus PORT and WPRT plus AHT at long-term follow-up albeit increased risk of grade 3 or worse intestinal toxicity. Interactions between radiotherapy and hormonal therapy suggests that WPRT should be avoided without NHT. FUNDING: National Cancer Institute.

ABSTRACT

Non-inferiority in the cumulative castration rate of the 3-month formulation of degarelix compared with the 3-month formulation of goserelin was evaluated in subjects with prostate cancer. A phase III, open-label, parallel-arm study was carried out. An initial dose of 240 mg degarelix or 3.6 mg goserelin was given s.c.; after day 28, a maintenance dose of 480 mg degarelix or 10.8 mg goserelin was given once every 84 days. Non-inferiority in castration rate and safety of degarelix to goserelin were evaluated. The primary end-point was the cumulative castration rate from day 28 to day 364 and the non-inferiority margin was set to be 10%. A total of 234 subjects with prostate cancer were randomized to the degarelix group (n = 117) and the goserelin group (n = 117). The cumulative castration rate was 95.1% in the degarelix group and 100.0% in the goserelin group. As there were no events in the goserelin group, an additional analysis was carried out using 95% confidence intervals of the difference in the proportion of subjects with castration. Analyses indicated the non-inferiority of the 3-month formulation of degarelix to goserelin. Degarelix showed more rapid decreases in testosterone, luteinizing hormone, follicle stimulating hormone, and prostate-specific antigen levels compared with goserelin. The most common adverse events in the degarelix group were injection site reactions. Non-inferiority of the 3-month formulation of degarelix to goserelin was shown for testosterone suppression. The 3-month formulation of degarelix was also found to be tolerated as an androgen deprivation therapy for patients with prostate cancer. This trial was registered with ClinicalTrials.gov (identifier NCT01964170).

ABSTRACT

AIM: of this study is to determine the temporal resolution of therapy-induced pneumonitis, and to assess promoting factors in adjuvant treated patients with unilateral mammacarcinoma. PATIENTS AND METHODS: A total of 100 post-surgery patients were recruited. The cohort was treated by 2 field radiotherapy (2FRT; breast and chest wall, N = 75), 3 field radiotherapy (3FRT; + supraclavicular lymphatic region, N = 8), or with 4 field radiotherapy (4FRT; + parasternal lymphatic region, N = 17). Ninety-one patients received various systemic treatments prior to irradiation. Following an initial screening visit post-RT, two additional visits after 12 and 25 weeks were conducted including radiographic examination. In addition, general anamnesis and the co-medication were recorded. The endpoint was reached as soon as a pneumonitis was developed or at maximum of six months post-treatment. RESULTS: A pneumonitis incidence of 13% was determined. Of 91 patients with prior systemic therapy, 11 patients developed pneumonitis. Smoking history and chronic obstructive pulmonary disease (COPD) appeared to be positive predictors, whereas past pneumonia clearly promoted pneumonitis. Further pneumonitis-promoting predictors are represented by the applied field extensions (2 field radiotherapy [2FRT] < 3 field radiotherapy [3FRT] < 4 field radiotherapy [4FRT]) and the type of combined initial systemic therapies. As a consequence, all of the three patients in the study cohort treated with 4FRT and initial chemotherapy combined with anti-hormone and antibody protocols developed pneumonitis. A combination of the hormone antagonists tamoxifen and goserelin might enhance the risk for pneumonitis. Remarkably, none of the 11 patients co-medicated with statins suffered from pneumonitis. CONCLUSIONS: The rapidly increasing use of novel systemic therapy schedules combined with radiotherapy (RT) needs more prospective studies with larger cohorts. Our results indicate that contribution to pneumonitis occurrence of various (neo)adjuvant therapy approaches followed by RT is of minor relevance, whereas mean total lung doses of >10 Gy escalate the risk of lung tissue complications. The validity of potential inhibitors of therapy-induced pneumonitis as observed for statin co-medication should further be investigated in future trials.

ABSTRACT

PURPOSE: Among harmful effects of chemotherapy is the reduction of ovarian function. The aim was to determine the serum levels of FSH, LH, estradiol and AMH after chemotherapy followed by endocrine therapy in breast cancer patients. METHODS: The study included 40 premenopausal hormone receptor-positive breast cancer patients aged 33-50 years. Anthracycline-based chemotherapy received 14/40 while anthracycline-taxane combination received 26/40 of patients, followed by tamoxifen (30/40) or tamoxifen plus goserelin (10/40). All of them experienced chemotherapy-induced secondary amenorrhea. Hormone levels were determined by ELISA. Statistics included Spearman's test, Mann-Whitney test and multiple linear regression analysis. RESULTS: Undetectable AMH levels were observed in 62.5 and 33.3% of patients with time period < 2 and ≥ 2 years from completion of chemotherapy to sample collection. Median levels of hormones for patients treated with anthracycline-based compared to anthracycline-taxane therapy were: 15.5 vs. 22.3 IU/L for FSH; 10.9 vs. 13.6 IU/L for LH; 55.5 vs. 39.5 pg/mL for estradiol; 0.11 vs. 0.11 ng/mL for AMH. The multiple linear regression showed that: women who received goserelin had significantly lower FSH; those with shorter time from completion of chemotherapy to sample collection had significantly higher LH and lower estradiol; younger women had higher AMH levels. CONCLUSIONS: The ovarian function was recovered from chemotherapy-induced secondary amenorrhea with time elapsed since the completion of adjuvant chemotherapy. It may be less disrupted in patients who received anthracycline-based chemotherapy and goserelin plus tamoxifen, as well.

ABSTRACT

BACKGROUND: Chemotherapy-induced premature ovarian insufficiency (POI) impacts fertility and other aspects of women's health. The OPTION trial tested whether administration of a gonadotropin-releasing hormone agonist during chemotherapy for early breast cancer reduced the risk of POI. PATIENTS AND METHODS: This was a prospective, randomized, parallel group study of the gonadotropin-releasing hormone agonist goserelin administered before and during chemotherapy for breast cancer with stage I-IIIB disease. The primary outcome was amenorrhoea between 12 and 24 months after randomization, supported by elevated follicle stimulating hormone concentrations to give an additional analysis as rate of POI. RESULTS: A total of 227 patients were randomized and the primary analysis was conducted on 202 patients. Goserelin reduced the prevalence of amenorrhoea between 12 and 24 months to 22% versus 38% in the control group (P = 0.015) and the prevalence of POI to 18.5% versus 34.8% in the control group (P = 0.048). Follicle stimulating hormone concentrations were also lower in all women treated with goserelin at both 12 and 24 months (P = 0.027, P = 0.001, respectively). The effect of goserelin was not statistically significant in women >40 years. Assessment of the ovarian reserve using anti-Müllerian hormone showed a marked fall in both groups during treatment to median values of 5% of pretreatment levels in the control group and 7% in the goserelin group, which were not significantly different between groups. CONCLUSION: This study shows that goserelin reduced the risk of POI in women treated with chemotherapy for early breast cancer, with particular efficacy in women aged ≤40 years old. The degree of ovarian protection also seems limited and the clinical significance for fertility and longer term prevention of estrogen deficiency-related outcomes needs to be determined.

ABSTRACT

BACKGROUND: The optimal treatment for high-risk prostate cancer (PCa) remains to be established. We previously reported favorable, biochemical recurrence-free survival in high-risk PCa patients treated with a neoadjuvant gonadotropin-releasing hormone agonist or antagonist and estramustine phosphate (EMP) (chemohormonal therapy; CHT) followed by radical prostatectomy (RP). We conducted a retrospective study to elucidate the clinical benefit of neoadjuvant CHT for high-risk PCa patients. METHODS: We reviewed the clinical and pathological records of 1254 PCa patients who underwent RP and bilateral pelvic lymphadenectomy between July 1996 and April 2016 at Hirosaki University. According to the D'Amico risk classification, we focused on 613 patients in the high-risk group. The high-risk PCa patients were further divided into two groups based on whether the patients received neoadjuvant CHT before RP (EMP group) or not (non-EMP group). The endpoint was overall survival (OS) after surgery. RESULTS: The 5- and 10-year OS rates were 98.5 and 92.6%, respectively. The 10-year OS rate in the EMP group was significantly higher compared to the non-EMP group (P = 0.021). In multivariate analysis, administration of neoadjuvant CHT, lymph node involvement, and castration-resistant PCa status were significantly associated with OS. CONCLUSIONS: RP with neoadjuvant CHT using EMP for high-risk PCa patients provided excellent long-term OS.

ABSTRACT

OBJECTIVE: To investigate the clinical effects of integrated traditional Chinese and Western medicine in the treatment of castration-resistant prostate cancer (CRPC). METHODS: A total of 54 CRPC patients were randomly divided into a control and a trial group, all treated by endocrine therapy (oral Bicalutamide at 50 mg per d plus subcutaneous injection of Goserelin at 3.6 mg once every 4 wk) and chemotherapy (intravenous injection of Docetaxel at 75 mg/m2 once every 3 wk plus oral Prednisone at 5 mg bid), while the latter group by Fuyang Huayu Prescription (a Traditional Chinese Medicine ï¼»TCMï¼½ prescription for tonifying yang and dispersing blood stasis) in addition, for a course of 24 weeks. Comparisons were made between the two groups of patients in the level of serum prostate-specific antigen (PSA), Karnofsky physical condition scores, function assessment of cancer therapy-prostate (FACT-P) scores, and TCM symptoms scores before and after 12 or 24 weeks of treatment. RESULTS: Compared with the baseline, the serum PSA level was significantly decreased after 12 weeks of treatment both in the control (ï¼»25.9 ± 39.3ï¼½ vs ï¼»20.0 ± 21.1ï¼½ µg/L, P <0.05) and in the trial group (ï¼»22.1 ± 33.9ï¼½ vs ï¼»17.9 ± 19.1ï¼½ µg/L, P <0.05), with no statistically significant differences between the two groups (P >0.05). At 24 weeks, however, the PSA levels in the control and trial groups were slightly increased to (23.1 ± 28.4) and (19.6 ± 23.5) µg/L, respectively, with no statistically significant differences in between (P >0.05). Karnofsky, FACT-P and TCM symptoms scores were all markedly improved in the trial group after 12 weeks of treatment (P <0.05) and remained stable at 24 weeks, but not in the control group either at 12 or at 24 weeks (P >0.05). CONCLUSIONS: TCM Fuyang Huayu Prescription combined with endocrine therapy and chemotherapy is effective for CRPC.

ABSTRACT

BACKGROUND: Current approaches to diagnosing testosterone deficiency do not consider the physiological consequences of various testosterone levels or whether deficiencies of testosterone, estradiol, or both account for clinical manifestations. METHODS: We provided 198 healthy men 20 to 50 years of age with goserelin acetate (to suppress endogenous testosterone and estradiol) and randomly assigned them to receive a placebo gel or 1.25 g, 2.5 g, 5 g, or 10 g of testosterone gel daily for 16 weeks. Another 202 healthy men received goserelin acetate, placebo gel or testosterone gel, and anastrozole (to suppress the conversion of testosterone to estradiol). Changes in the percentage of body fat and in lean mass were the primary outcomes. Subcutaneous- and intraabdominal-fat areas, thigh-muscle area and strength, and sexual function were also assessed. RESULTS: The percentage of body fat increased in groups receiving placebo or 1.25 g or 2.5 g of testosterone daily without anastrozole (mean testosterone level, 44±13 ng per deciliter, 191±78 ng per deciliter, and 337±173 ng per deciliter, respectively). Lean mass and thigh-muscle area decreased in men receiving placebo and in those receiving 1.25 g of testosterone daily without anastrozole. Leg-press strength fell only with placebo administration. In general, sexual desire declined as the testosterone dose was reduced. CONCLUSIONS: The amount of testosterone required to maintain lean mass, fat mass, strength, and sexual function varied widely in men. Androgen deficiency accounted for decreases in lean mass, muscle size, and strength; estrogen deficiency primarily accounted for increases in body fat; and both contributed to the decline in sexual function. Our findings support changes in the approach to evaluation and management of hypogonadism in men. (Funded by the National Institutes of Health and others; ClinicalTrials.gov number, NCT00114114.).

ABSTRACT

BACKGROUND: Castration resistance occurs in most patients with metastatic hormone-sensitive prostate cancer who are receiving androgen-deprivation therapy. Replacing androgens before progression of the disease is hypothesized to prolong androgen dependence. METHODS: Men with newly diagnosed, metastatic, hormone-sensitive prostate cancer, a performance status of 0 to 2, and a prostate-specific antigen (PSA) level of 5 ng per milliliter or higher received a luteinizing hormone-releasing hormone analogue and an antiandrogen agent for 7 months. We then randomly assigned patients in whom the PSA level fell to 4 ng per milliliter or lower to continuous or intermittent androgen deprivation, with patients stratified according to prior or no prior hormonal therapy, performance status, and extent of disease (minimal or extensive). The coprimary objectives were to assess whether intermittent therapy was noninferior to continuous therapy with respect to survival, with a one-sided test with an upper boundary of the hazard ratio of 1.20, and whether quality of life differed between the groups 3 months after randomization. RESULTS: A total of 3040 patients were enrolled, of whom 1535 were included in the analysis: 765 randomly assigned to continuous androgen deprivation and 770 assigned to intermittent androgen deprivation. The median follow-up period was 9.8 years. Median survival was 5.8 years in the continuous-therapy group and 5.1 years in the intermittent-therapy group (hazard ratio for death with intermittent therapy, 1.10; 90% confidence interval, 0.99 to 1.23). Intermittent therapy was associated with better erectile function and mental health (P<0.001 and P=0.003, respectively) at month 3 but not thereafter. There were no significant differences between the groups in the number of treatment-related high-grade adverse events. CONCLUSIONS: Our findings were statistically inconclusive. In patients with metastatic hormone-sensitive prostate cancer, the confidence interval for survival exceeded the upper boundary for noninferiority, suggesting that we cannot rule out a 20% greater risk of death with intermittent therapy than with continuous therapy, but too few events occurred to rule out significant inferiority of intermittent therapy. Intermittent therapy resulted in small improvements in quality of life. (Funded by the National Cancer Institute and others; ClinicalTrials.gov number, NCT00002651.).

ABSTRACT

BACKGROUND: Ovarian function suppression (OFS) has been shown to be effective as adjuvant endocrine therapy in premenopausal women with hormone receptor-positive breast cancer. However, it is currently unclear if addition of OFS to standard tamoxifen therapy after completion of adjuvant chemotherapy results in a survival benefit. In 2008, the Korean Breast Cancer Society Study Group initiated the ASTRRA randomized phase III trial to evaluate the efficacy of OFS in addition to standard tamoxifen treatment in hormone receptor-positive breast cancer patients who remain or regain premenopausal status after chemotherapy. METHODS: Premenopausal women with estrogen receptor-positive breast cancer treated with definitive surgery were enrolled after completion of neoadjuvant or adjuvant chemotherapy. Ovarian function was assessed at the time of enrollment and every 6 months for 2 years by follicular-stimulating hormone levels and bleeding history. If ovarian function was confirmed as premenopausal status, the patient was randomized to receive 2 years of goserelin plus 5 years of tamoxifen treatment or 5 years of tamoxifen alone. The primary end point will be the comparison of the 5-year disease-free survival rates between the OFS and tamoxifen alone groups. Patient recruitment was finished on March 2014 with the inclusion of a total of 1483 patients. The interim analysis will be performed at the time of the observation of the 187th event. DISCUSSION: This study will provide evidence of the benefit of OFS plus tamoxifen compared with tamoxifen only in premenopausal patients with estrogen receptor-positive breast cancer treated with chemotherapy.
