A taste alteration-related scale assesses megestrol to improve chemotherapy-induced anorexia.

PURPOSE: We evaluated the efficacy of megestrol in improving chemotherapy-related anorexia by analyzing the related scales of taste alteration. METHODS: We conducted the current study on a group of advanced patients with cancer with two or more chemotherapy cycles. The chemotherapy-induced taste alteration scale (CiTAs) scale helped assess the megestrol effects on basic taste perception, aversive taste changes, unpleasant symptoms, and associated concerns. Furthermore, the Short Nutritional Assessment Questionnaire scale (SNAQ) helped measure the impact of megestrol on malnutrition likelihood in patients experiencing chemotherapy-induced anorexia. The World Health Organization Quality of Life (WHOQOL)-BREF Scale was used to evaluate the quality of life of participants, producing scores related to physical health, psychological well-being, environmental factors, and social relationships. RESULTS: The CiTAs scale assessment indicated that administering megestrol significantly enhanced taste perception among advanced patients with cancer undergoing chemotherapy. Notably, the megestrol group patients showed significantly higher Short Nutritional Assessment Questionnaire (SNAQ) scores than the control group. The megestrol group patients also exhibited higher physiological (PHYS) scores than their control group counterparts. However, this distinction was not statistically significant. The study findings indicate that patients who received megestrol demonstrated significantly higher scores in psychological (PSYCH) and environmental(ENVIR) domains than the control group. Furthermore, megestrol administration was associated with significantly elevated SOCIL and ENVIR levels in patients. CONCLUSION: The proficient efficacy evaluation of megestrol in enhancing appetite, mitigating malnutrition likelihood, and improving the quality of life of chemotherapy-induced anorexic patients can be achieved through taste-related scales.

Mirtazapine versus megestrol acetate in treatment of anorexia-cachexia in advanced cancer patients: a randomized, double-blind trial.

OBJECTIVE: Cancer-related anorexia-cachexia comprises one of the most common syndromes of advanced cancer patients. The management of cancer-related anorexia-cachexia is a great challenge in clinical practice. There are no definite practice guidelines yet for the prevention and treatment of cancer-related anorexia-cachexia. This study is considered to find out whether there is any role of mirtazapine in the improvement of anorexia in cancer patients. METHODS: A total of 80 cancer-anorexia patients were enrolled. Patients in the trial arm received the standard chemotherapy medication plus one tablet of mirtazapine 15 mg daily at night orally for 8 weeks starting from the day of an initial assessment. The control arm received the standard chemotherapy medication plus one tablet of megestrol acetate 160 mg daily orally for 8 weeks starting from the day of an initial assessment. Each patient was assessed by validated versions of Functional Assessment of Anorexia/Cachexia Therapy Anorexia/Cachexia Sub Scale v 4 questionnaires. RESULTS: After 4 and 8 weeks each patient was evaluated again using the Functional Assessment of Anorexia/Cachexia Therapy Anorexia/Cachexia Sub Scale tool. The quality of life of each patient was assessed by European Organization for Research and Treatment QLQ-C30 v 3.0. After 4 to 8 weeks of treatment, the Functional Assessment of Anorexia/Cachexia Therapy Anorexia/Cachexia Sub Scale score in cancer anorexia patients in the mirtazapine improved anorexia significantly. However, the improvement after 4 to 8 weeks was not statistically significant when it was compared with the megestrol acetate (P > 0.05). CONCLUSIONS: Therefore, the findings of this study reveal that mirtazapine might be a potential alternative to megestrol acetate, as it has shown potential efficacy as like as megestrol acetate.

A randomised, double blind, placebo-controlled trial of megestrol acetate or dexamethasone in treating symptomatic anorexia in people with advanced cancer.

This multi-site, double blind, parallel arm, fixed dose, randomised placebo controlled phase III study compared megestrol acetate 480 mg/day with dexamethasone 4 mg/day for their net effects on appetite in people with cancer anorexia. Patients with advanced cancer and anorexia for ≥ 2 weeks with a score ≤ 4 (0-10 numeric rating scale (NRS) 0 = no appetite, 10 = best possible appetite) were recruited. Participants received megestrol 480 mg or dexamethasone 4 mg or placebo daily for up to 4 weeks. Primary outcomes were at day 7. Responders were defined as having a ≥ 25% improvement in NRS over baseline. There were 190 people randomised (megestrol acetate n = 61; dexamethasone n = 67, placebo n = 62). At week 1 (primary endpoint), 79·3% in the megestrol group, 65·5% in the dexamethasone group and 58·5% in the placebo group (p = 0.067) were responders. No differences in performance status or quality of life were reported. Treatment emergent adverse events were frequent (90·4% of participants), and included altered mood and insomnia. Hyperglycemia and deep vein thromboses were more frequent when on dexamethasone than the other two arms. There was no difference in groups between the three arms, with no benefit seen over placebo with anorexia improving in all arms.Trail registration: The trial was registered on 19/08/2008 with the Australian New Zealand Clinical Trials Registry (ACTRN12608000405314).

Continued medical treatment for persistent early endometrial cancer in young women.

OBJECTIVE: We aimed to investigate the effectiveness of continuing medical therapy in patients who did not achieve complete response (CR) despite 9 months of progestin treatment. We also sought to determine the prognostic factors associated with achieving CR among these patients. METHODS: We retrospectively analyzed 51 patients with presumed stage IA, grade 1 or 2 endometrioid adenocarcinoma who had persistent disease on biopsy performed at 9-12 months after at least 9 months of progestin-based therapy. Data on clinicopathological factors and oncological and obstetrical outcomes following continuous hormonal treatment were extracted from the patients' medical records and analyzed. Univariate and multivariate analyses for predicting CR were performed. RESULTS: Thirty-seven (72.5%) of 51 patients achieved CR after prolonged fertility-sparing treatment. Median time to CR from starting initial progestin was 17.3 months (range, 12.1-91.7 months). On univariate analysis, history of polycystic ovarian syndrome, histologic grade 2, and not achieving partial response (PR) until 12 months were significantly associated with failure to CR (odds ratio [OR], 6.188, 95% confidence interval [CI], 1.405-27.244, p = 0.018; OR, 9.722, 95% CI, 1.614-58.581, p = 0.013; and OR, 21.750, 95% CI, 4.016-117.783, p < 0.001, respectively). Multivariate analysis revealed that not achieving PR until 12 months was an independent prognostic factor predicting failure to CR after prolonged progestin therapy (OR, 21.803, 95% CI, 3.601-132.025, p = 0.001). CONCLUSIONS: Continued medical treatment is effective for persistent early endometrial carcinoma after at least 9 months of progestin therapy in young women who want to preserve their fertility.

Efficacy and safety of pharmacological cachexia interventions: systematic review and network meta-analysis.

AIMS: Randomised controlled trials (RCTs) demonstrated benefits of pharmacological interventions for cachexia in improving weight and appetite. However, comparative efficacy and safety are not available. We conducted a systematic review and network meta-analysis (NMA) to evaluate the relative efficacy and safety of pharmacological interventions for cachexia. METHODS: PubMed, EmBase, Cochrane, and ClinicalTrials.gov were searched for RCTs until October 2019. Key outcomes were total body weight (TBW) improvement, appetite (APP) score and serious adverse events. Two reviewers independently extracted data and assessed risk of bias. NMA was performed to estimate weight gain and APP score increase at 8 weeks, presented as mean difference (MD) or standardised MD with 95% CI. RESULTS: 80 RCTs (10 579 patients) with 12 treatments were included. Majority is patients with cancer (7220). Compared with placebo, corticosteroids, high-dose megestrol acetate combination (Megace_H_Com) (≥400 mg/day), medroxyprogesterone, high-dose megestrol acetate (Megace_H) (≥400 mg/day), ghrelin mimetic and androgen analogues (Androgen) were significantly associated with MD of TBW of 6.45 (95% CI 2.45 to 10.45), 4.29 (95% CI 2.23 to 6.35), 3.18 (95% CI 0.94 to 5.41), 2.66 (95% CI 1.47 to 3.85), 1.73 (95% CI 0.27 to 3.20) and 1.50 (95% CI 0.56 to 2.44) kg. For appetite improvement, Megace_H_Com, Megace_H and Androgen significantly improved standardised APP score, compared with placebo. There is no significant difference in serious adverse events from all interventions compared with placebo. CONCLUSIONS: Our findings suggest that several pharmacological interventions have potential to offer benefits in treatment of cachexia especially Megace_H and short-term use corticosteroids. Nonetheless, high-quality comparative studies to compare safety and efficacy are warranted for better management of cachexia.

Oncologic and obstetrical outcomes after fertility-preserving retreatment in patients with recurrent atypical endometrial hyperplasia and endometrial cancer.

OBJECTIVE: A number of patients with atypical endometrial hyperplasia and endometrial cancer have not yet given birth when they relapse after achieving complete response with initial fertility-preserving treatment. Often such patients still have a strong desire for fertility preservation; however, there are limited reports in the related literature on the efficacy of fertility-preserving retreatment in patients with relapse. This study intends to evaluate the safety and efficacy of fertility-preserving retreatment in patients with atypical endometrial hyperplasia and endometrial cancer after recurrence following initial fertility-preserving treatment. METHODS: Data from 110 patients with atypical endometrial hyperplasia and endometrial cancer who received fertility-preserving treatment in the Department of Obstetrics and Gynecology, Peking University People's Hospital (December 2005 to September 2019) were collected, and a retrospective analysis was performed on the clinical characteristics, histopathology results, and outcomes of 25 patients with recurrence. RESULTS: 25 patients (9 with atypical endometrial hyperplasia and 16 with endometrial cancer) received fertility-preserving retreatment. After a median treatment duration of 5 months (range 3-18), 21 patients (84%, 21/25) achieved complete response and 4 patients (16%, 4/25) had a partial response. The median follow-up time was 19.5 months (range 8-76), and a total of 8 patients (38.1%, 8/21) relapsed. The time from retreatment to complete response for endometrial cancer was significantly longer than that for atypical endometrial hyperplasia (7.5 vs 3 months; p=0.007). Among the 21 patients who achieved complete response, 12 patients had a desire for fertility, among whom 8 patients had a successful pregnancy (66.7%, 8/12) and 6 patients experienced term birth (1 patient with natural pregnancy and 5 patients with assisted reproductive technology). Six patients (50%, 6/12) delivered 6 full-term babies. CONCLUSION: The response rate is high and obstetrical outcomes are favorable after fertility-preserving retreatment in patients with recurrence of atypical endometrial hyperplasia and endometrial cancer.

Metformin plus megestrol acetate compared with megestrol acetate alone as fertility-sparing treatment in patients with atypical endometrial hyperplasia and well-differentiated endometrial cancer: a randomised controlled trial.

OBJECTIVE: To assess the efficacy of metformin in megestrol acetate (MA)-based fertility-sparing treatment for patients with atypical endometrial hyperplasia (AEH) and endometrioid endometrial cancer (EEC). DESIGN: A randomised, single-centre, open-label, controlled trial conducted between October 2013 and December 2017. SETTING: Shanghai OBGYN Hospital of Fudan University, China. POPULATION: A total of 150 patients (18-45 years old) with primary AEH or well-differentiated EEC were randomised into an MA group (n = 74) and an MA plus metformin group (n = 76). METHODS: Patients with AEH or EEC were firstly stratified, then randomised to receive MA (160 mg orally, daily) or MA (160 mg orally, daily) plus metformin (500 mg orally, three times a day). MAIN OUTCOMES AND MEASURES: The primary efficacy parameter was the cumulate complete response (CR) rate within 16 weeks of treatment (16w-CR rate); the secondary efficacy parameters were 30w-CR rate and adverse events. RESULTS: The 16w-CR rate was higher in the metformin plus MA group than in the MA-only group (34.3 versus 20.7%, odds ratio [OR] 2.0, 95% confidence interval [CI] 0.89-4.51, P = 0.09) but the difference was more significant in 102 AEH patients (39.6 versus 20.4%, OR 2.56, 95% CI 1.06-6.21, P = 0.04). This effect of metformin was also significant in non-obese (51.4 versus 24.3%, OR 3.28, 95% CI 1.22-8.84, P = 0.02) and insulin-sensitive (54.8 versus 28.6%, OR 3.04, 95% CI 1.03-8.97, P = 0.04) subgroups of AEH women. No significant result was found in secondary endpoints. CONCLUSION: As a fertility-sparing treatment, metformin plus MA was associated with a higher early CR rate compared with MA alone in AEH patients. TWEETABLE ABSTRACT: For AEH patients, metformin plus MA might be a better fertility-sparing treatment to achieve a higher early CR rate compared with MA alone.

Treatment efficiency of comprehensive hysteroscopic evaluation and lesion resection combined with progestin therapy in young women with endometrial atypical hyperplasia and endometrial cancer.

OBJECTIVE: This study aimed to evaluate the efficacy of comprehensive hysteroscopic evaluation and lesion resection combined with progestin therapy in young patients with endometrial atypical hyperplasia (EAH) and early stage endometrial cancer (EEC) who wished to preserve their fertility. METHODS: Patients with EAH (n = 120) or well-differentiated EEC (n = 40, FIGO stage IA, without myometrial invasion) were retrospectively included. All patients received constant oral progestin combined with hysteroscopic evaluation every 3 months until achieving complete response (CR). The location, number and size of each suspected lesion or cluster were detailly recorded during the hysteroscopy. RESULTS: The median age was 32.0 year-old (range, 22-47 year-old). Totally 148 patients (97.4%) achieved CR while 3 EAH and 1 EEC patients presented with disease progression, and 8 patients were still in treatment. The mean treatment duration for achieving CR was 6.7 ±â€¯0.3 months (range, 1-18 months). After adjusting for patient age, body mass index (BMI), history of pregnancy and type of conservative therapies, lesion size ≤2 cm (OR, 0.701; 95% CI, 0.496-0.991; P = 0.045) was significantly correlated with shorter treatment time to achieve CR. Among 60 patients attempted to conceive after achieving CR, 45.0% (15/60) had been pregnant, 25.0% (15/60) delivered live birth, 13.3% (8/60) are still in pregnancy, while 6.7% experienced spontaneous abortion. CONCLUSION: Comprehensive hysteroscopic evaluation and lesion resection plus progestin therapy seem to be an effective and safe fertility sparing therapy for patients with EAH or EEC. Endometrial lesion size ≤2 cm correlated with a shorter treatment period to achieve CR.

Fabrication of Eudragit polymeric nanoparticles using ultrasonic nebulization method for enhanced oral absorption of megestrol acetate.

Megestrol acetate (MGA) is used as a progestagen to treat advanced cancers in the breast or uterus and anorexia-cachexia syndrome in cancer patients. Due to its low solubility (BCS class II), MGA bioavailability needs to be enhanced for efficacy and safety. We developed MGA-encapsulated Eudragit® L100 (EUD) nanoparticles (MGA-EUD (1:1) and MGA-EUD (2:1)) using an ultrasonic nebulization method. MGA-EUD (1:1) and MGA-EUD (2:1) consisted of MGA and EUD at the mass ratios of 1:1 and 2:1. Their physicochemical properties, i.e. particle size, loading efficiency, morphology, and crystallinity were determined. Dissolution tests were performed using USP method II. For pharmacokinetics, they were orally administered at 50 mg/kg to mice. Microcrystalline MGA suspension (MGA-MC, Megace®, BMS) was used as control. MGA-EUD (1:1) and MGA-EUD (2:1) had a smooth and spherical shape of 0.70 and 1.05 µm in diameter with loading efficiencies of 93 and 95% showing amorphous states of MGA. They significantly enhanced the dissolution potential of MGA. Oral bioavailability of MGA-EUD (1:1) and MGA-EUD (2:1) increased 2.0- and 1.7-fold compared to that of MGA-MC. It suggests that ultrasonic nebulization method for the fabrication of polymeric nanoparticles is a promising approach to improve the bioavailability of poorly soluble drugs.

A successful live birth with in vitro fertilization and thawed embryo transfer after conservative treatment of recurrent endometrial cancer.

Estrogen-dependent early stage endometrial cancer is relatively common in young women of reproductive age. The standard treatment is hysterectomy and bilateral salpingo-oophorectomy (BSO), even in early stage well-differentiated endometrial cancer patients. This surgical option results in permanent loss of fertility. There have been some reports of live births using in vitro fertilization after conservative management of endometrial cancer with high-dose progestin for the purpose of fertility preservation. However, most were not recurrent cases and pregnancy was achieved through conventional in vitro fertilization, which usually raises serum estradiol levels and may lead to the recurrence of endometrial cancer. To date, it is hard to find a case that can be referred for any possible different approach needed for the patients who experience recurrence. Here we report a successful live birth with in vitro fertilization using letrozole to maintain physiological levels of estradiol, and subsequent thawed embryo transfer after elective cryopreservation of embryos in a patient with recurrent endometrial cancer. There has been no evidence of disease recurrence at one year after delivery.

Fertility Preserved Hysteroscopic Approach for the Treatment of Stage Ia Endometrioid Carcinoma.

OBJECTIVE: This study aims to explore the feasibility of a hysteroscopic procedure combined with progestin therapy in young patients with stage Ia endometrioid carcinoma (EC) to avoid sterilization. MATERIALS AND METHODS: Eleven young women with stage Ia EC (International Federation of Gynecology and Obstetrics grade 1) who were treated with a hysteroscopic approach combined with progestin from July 2004 to June 2016 were retrospectively analyzed and followed up to monitor their general recovery and pregnancy outcome. RESULTS: The patients' median age was 27.3 years (range, 25-39 years). Comorbidities consisted of primary infertility in 8 patients, polycystic ovary syndrome in 4, uterine fibroids in 2, and diabetes in 1. The results of immunohistochemical analysis were positive for all estrogen and progestin receptors. After treatment, 9 patients attained complete remission, and 2 patients achieved partial remission. The results of peritoneal cytology in 4 patients were negative. As of this writing, 6 of the 11 patients have given birth to 7 infants, and 1 patient had an ectopic pregnancy. Two patients ultimately underwent radical resection. The average follow-up time was 82.3 months (range, 15 to 152 months), and all patients remain disease-free. CONCLUSIONS: Hysteroscopic surgery combined with progestin treatment for stage Ia EC in young patients to avoid sterilization was practical and may represent a new option for patients with stage Ia EC who wish to preserve their fertility.

Significance of body weight change during fertility-sparing progestin therapy in young women with early endometrial cancer.

OBJECTIVE: To evaluate the influence of body weight change during fertility-sparing progestin therapy on oncologic and reproductive outcomes in young women with early-stage endometrial cancer who did not complete child bearing. METHODS: This multicenter, retrospective study included 154 young patients with well-differentiated, endometrium-confined endometrioid endometrial adenocarcinoma on magnetic resonance imaging who received fertility-sparing progestin therapy. RESULTS: The mean body weight and body mass index (BMI) at baseline and progestin therapy completion was 65.3±16.2 and 66.5±15.9kg (P=0.044), respectively, and 25.51±5.99 and 25.99±5.94kg/m2 (P=0.034), respectively. During progestin therapy, 51 (33.1%), 29 (18.8%), and 74 patients (48.1%) had weight loss, no weight change, and weight gain, respectively, of which 11 (7.1%) had 10% weight loss and 30 (19.5%) had 10% weight gain. A pretreatment BMI of ≥25kg/m2 was significantly associated with a lower complete response rate to progestin therapy (P=0.003) and a high recurrence rate (P=0.033). A posttreatment BMI of ≥25kg/m2 was also a significant factor for high recurrence rate (P=0.049). However, weight change during therapy was not significantly associated with complete response or recurrence rate. Pre and posttreatment BMIs and weight change were not associated with pregnancy and live birth rates. CONCLUSION: Weight change during progestin therapy has little influence on complete response, recurrence, pregnancy, and live birth rates. However, pre and posttreatment BMIs of ≥25kg/m2 were significant predictors for poor treatment response and high recurrence. Therefore, it is important to maintain patients' normal BMIs during progestin therapy.

Quantitative Assessment of Food Effect on the Pharmacokinetics of Nano-Crystallized Megestrol Acetate.

Megestrol acetate, an appetite stimulant with low bioavailability, shows increased bioavailability when taken together with food. However, the pharmacokinetic characteristics of megestrol acetate and its relation with food are not well understood. This study aimed to investigate the food effect on the pharmacokinetics (PK) of the recently developed nano-crystallized megestrol acetate (NCMA), using a model-based approach. Data were obtained from an NCMA PK study consisting of a single dose in fasting (39 individuals) and fed conditions (40 individuals). Plasma concentrations were measured up to 120 hr after dosing. With the incorporation of body-weight via allometry, NONMEM 7.3 was used to develop a PK model, which was then used to simulate an optimal fasting dose yielding an area under concentration (AUC) and maximum concentration (Cmax ) of NCMA close to those obtained with the fed dose. NCMA concentrations were best characterized by a two-compartment model with first-order absorption linked to a recycling compartment to account for the multiple concentration peaks observed. Food increased bioavailability 2.2 times and decreased the absorption rate constant 0.58 times. Recycling event times were estimated to be 3.56, 7.99 and 24.0 hr. The optimal fast dose was 2.0 times higher than the fed dose, and the resulting difference in drug exposure between the fasting and fed dose was 7.5%. This work suggests that the PK model developed can be applied to an optimal dosage regimen design for NCMA treatment.

Fertility preserving treatment with hysteroscopic resection followed by progestin therapy in young women with early endometrial cancer.

OBJECTIVE: To report our 15-year institutional experience of fertility-sparing treatment in young patients with early endometrial cancer (EC) treated by combined hysteroscopic resection and progestin therapy. METHODS: Twenty-eight patients (stage IA, G1 and 2 endometrioid EC) wishing to preserve their fertility were enrolled into this prospective study. Hysteroscopic resection was used to resect the tumor, endometrium adjacent to the tumor and myometrium underlying the tumor. Adjuvant hormonal therapy consisted of oral megestrol acetate or levonorgestrel intrauterine device for 6 months or more. RESULTS: After 3 months from the progestin start date, 25 patients (89.3%) showed a complete regression (median time to complete regression, 3 months [range, 3-9 months]), two (7.1%) showed persistent disease, while one patient (3.6%) presented with progressive disease and underwent definitive surgery (stage IA, G3 endometrioid). At 6 months, one of the two patients with persistent disease underwent definitive surgery (stage IA, G1 endometrioid), while the other one was successfully re-treated. Two recurrences were observed (7.7%) both involving the endometrium and synchronous ovarian cancer. The median duration of complete response was 94.5 months (range, 8-175 months). More than half of the responders (57.7%) attempted to conceive with 93.3% and 86.6% pregnancy and live birth rates, respectively. CONCLUSION: The addition of a standardized three-step resectoscopy to progestin would seem to improve the efficacy of progestin alone. High pregnancy and live birth rates were observed in women attempting to conceive.

Tumor mutational analysis of GOG248, a phase II study of temsirolimus or temsirolimus and alternating megestrol acetate and tamoxifen for advanced endometrial cancer (EC): An NRG Oncology/Gynecologic Oncology Group study.

OBJECTIVE: Rapamycin analogs have reproducible but modest efficacy in endometrial cancer (EC). Identification of molecular biomarkers that predict benefit could guide clinical development. METHODS: Fixed primary tissue and whole blood were collected prospectively from patients enrolled on GOG 248. DNA was isolated from macro-dissected tumors and blood; next-generation sequence analysis was performed on a panel of cancer related genes. Associations between clinical outcomes [response rate (RR) 20%; progression-free survival (PFS) median 4.9months] and mutations (PTEN, PIK3CA, PIK3R1, KRAS, CTNNB1, AKT1, TSC1, TSC2, NF1, FBXW7) were explored. RESULTS: Sequencing data was obtained from tumors of 55 of the 73 enrolled pts. Mutation rates were consistent with published reports: mutations in PTEN (45%), PIK3CA (29%), PIK3R1 (24%), K-RAS (16%), CTNNB1 (18%) were common and mutations in AKT1 (4%), TSC1 (2%), TSC2 (2%), NF1 (9%) and FBXW7 (4%) were less common. Increased PFS (HR 0.16; 95% CI 0.01-0.78) and RR (response difference 0.83; 95% CI 0.03-0.99) were noted for AKT1 mutation. An increase in PFS (HR 0.46; 95% CI 0.20-0.97) but not RR (response difference 0.00, 95% CI -0.34-0.34) was identified for CTNNB1 mutation. Both patients with TSC mutations had an objective response. There were no statistically significant associations between mutations in PIK3CA, PTEN, PIK3R1, or KRAS and PFS or RR. CONCLUSIONS: Mutations in AKT1, TSC1 and TSC2 are rare, but may predict clinical benefit from temsirolimus. CTNNB1 mutations were associated with longer PFS on temsirolimus.

Oncologic and reproductive outcomes after fertility-sparing management with oral progestin for women with complex endometrial hyperplasia and endometrial cancer.

OBJECTIVE: To investigate the oncologic and reproductive outcomes after progestin treatment of complex endometrial hyperplasia (CEH) and grade 1 endometrial carcinoma (EC). METHODS: In a retrospective study, data were obtained for patients aged 20-42years with CEH or grade 1 EC at presumed stage IA (without myometrial invasion) who wished to preserve fertility and were treated at the Peking Union Medical College Hospital, China, between January 1, 2000, and December 31, 2011. Patients had received oral medroxyprogesterone acetate (250-500mg/day) or megestrol acetate (160-480mg/day) for at least 6months. Response to progestin treatment was assessed histologically. RESULTS: Among 53 included patients, 39 (74%) achieved complete response after a median period of 6 (3-24) months. Complete response was less frequent among obese than nonobese patients (4/12 [33%] vs 35/41 [85%]; P=0.001). Disease recurrence was recorded in 10 (26%) patients with complete response; the 5-year recurrence-free survival rate was 71%. Among the 33 patients who retained a desire to conceive, 17 (52%) became pregnant. CONCLUSION: Fertility-sparing management with oral progestin is effective. Obesity is associated with a lower probability of long-term success.

A Prospective Multicenter Study Evaluating Secondary Adrenal Suppression After Antiemetic Dexamethasone Therapy in Cancer Patients Receiving Chemotherapy: A Korean South West Oncology Group Study.

BACKGROUND: In a previous pilot study, adrenal suppression was found to be common after antiemetic dexamethasone therapy in cancer patients. The objective of this large prospective multicenter study was to confirm the incidence and factors associated with secondary adrenal suppression related to antiemetic dexamethasone therapy in cancer patients receiving chemotherapy. METHODS: Chemotherapy-naïve patients who were scheduled to receive at least three cycles of highly or moderately emetogenic chemotherapy with dexamethasone as an antiemetic were enrolled. Patients with a suppressed adrenal response before chemotherapy or those administered corticosteroids within 6 months of enrollment in the study were excluded. RESULTS: Between October 2010 and August 2014, 481 patients receiving chemotherapy underwent the rapid adrenocorticotropic hormone (ACTH) stimulation test to assess eligibility; 350 of these patients were included in the final analysis. Fifty-six patients (16.0%) showed a suppressed adrenal response in the rapid ACTH stimulation test at 3 or 6 months after the start of the first chemotherapy. The incidence of adrenal suppression was affected by age, performance status, stage, and use of megestrol acetate in univariate analysis. Multivariate analysis revealed that secondary adrenal suppression associated with antiemetic dexamethasone therapy was significantly associated with megestrol acetate treatment (odds ratio: 3.06; 95% confidence interval: 1.60 to 5.86; p < .001). CONCLUSION: This large prospective study indicates that approximately 15% of cancer patients receiving chemotherapy with a normal adrenal response show suppressed adrenal responses after antiemetic dexamethasone therapy. This result was particularly significant for patients cotreated with megestrol acetate.
