The Significance of Measuring Vitamin D Serum Levels in Women with Uterine Fibroids.

Uterine fibroids (UFs) are benign tumors originating from smooth muscle cells and are considered a common pathology that affects numerous women which is a notable socio-economic problem. Several UF risk factors have been identified including black race, obesity, and vitamin D deficiency. Vitamin D is steroid compound with pleiotropic effects on the human body. Vitamin D deficiency is a major public health concern worldwide. Several studies have shown that the majority of UF patients experienced hypovitaminosis D. In addition, sufficient vitamin D serum levels are associated with the reduced risk of UFs. In this review, we present available data highlighting the importance of measuring vitamin D serum levels in women with UFs and women at a high risk for UF development. We proposed a preliminary clinical instruction of 25-hydroxyvitamin D measurements and vitamin D supplementation for clinicians who are involved in the treatment of patients with UFs. Achieving sufficient serum levels of vitamin D might be of interest in patients with UFs. Screening, supplementation, treatment guidelines, and public health strategies for vitamin D deficiency in women with UFs as well as women at a high risk of UF development might be of potential importance as well.

Dietary fat intake, erythrocyte fatty acids, and risk of uterine fibroids.

OBJECTIVE: To prospectively evaluate the association between dietary fat intake and risk of uterine fibroids; and to evaluate the association between erythrocyte membrane fatty acid (FA) levels and fibroid risk. DESIGN: Prospective cohort study. Cox proportional hazard models were used to calculate hazard ratios and 95% confidence interval (CI). In a subset of participants 34 individual FAs were measured and logistic regression analysis was used to estimate odds ratios (ORs) and 95% CI for the association between FA tertiles and fibroids. SETTING: Not applicable. PATIENT(S): Premenopausal US women (81,590) in the Nurses' Health Study II, aged 25-42 years at enrollment in 1989 for whom diet was assessed by a food frequency questionnaire. A total of 553 participants with erythrocyte FA measurements. INTERVENTION(S): Not applicable. MAIN OUTCOME MEASURE(S): Cases of fibroids were defined on the basis of self-reported ultrasound or hysterectomy confirmation. RESULT(S): A total of 8,142 cases of ultrasound-confirmed or hysterectomy-confirmed were diagnosed during an 18-year period (1991-2009). No associations were observed between intake of any dietary fats and fibroids in the multivariable models. However, when erythrocyte FAs were examined, an inverse association was observed between total n-3 polyunsaturated FAs and likelihood of fibroids (OR for third versus first tertile, 0.41; 95% CI 0.19-0.89). In addition, total trans FAs were associated with more odds of fibroids (OR for third tertile, 3.33; 95% CI 1.50-7.38). CONCLUSION(S): Our findings provide preliminary suggestions that n-3 polyunsaturated FAs and trans FAs may play a role in fibroid etiology; however, these results should be confirmed in future studies.

Evaluation of High-Dose Vitamin A Treatment in Postmolar Patients with Low and Plateauing Serum Human Chorionic Gonadotropin Levels.

OBJECTIVE: To compare the effect of high-dose vitamin A (HD Vit-A) use during postmolar follow-up of patients with low and plateauing (L&P) serum human chorionic gonadotropin (hCG) levels, from the moment serum hCG plateaued (P-hCG) to the first normal serum hCG value (< 5 IU/L). METHODS: The present retrospective series case study compared two nonconcurrent cohorts of patients. Control group (CG): 34 patients with L&P serum hCG levels who underwent expectant management for 6 months after uterine evacuation, from 1992 to 2010; study group (SG): 32 patients in similar conditions who received 200,000 IU of Vit-A daily, from the identification of a P-hCG level to the first normal hCG value or the diagnosis of progression to gestational trophoblastic neoplasia (GTN), from 2011 to 2017. The present study was approved by the Ethics Committee of the institution where it was conducted. RESULTS: In both groups, the prevalence of persistent L&P serum hCG levels was < 5%. In the SG, hCG levels at plateau were higher (CG = 85.5 versus SG = 195 IU/L; p = 0.028), the rate of postmolar GTN was lower (CG = 29.4% versus SG = 6.3%, p = 0.034) and follow-up was shorter (CG = 14 versus SG = 10 months, p < 0.001). During GTN follow-up, there were no differences in GTN staging or treatment aggressiveness in both groups. High-dose Vit-A use did not have any relevant toxic effect. There were no GTN relapses or deaths. CONCLUSION: The limited use of HD Vit-A seems to have a safe and significant effect on the treatment of postmolar patients with L&P serum hCG levels and may decrease the development of postmolar GTN in this population.

OBJETIVO: Comparar o efeito de alta dose de vitamina A (VitA) no seguimento pós-molar de pacientes com gonadotrofina coriônica humana (hCG) sérica apresentando valores baixos e em platô (L&P). MéTODOS: Estudo retrospectivo de série de casos comparando duas coortes não simultâneas. Grupo controle (CG): 34 pacientes com títulos de hCG sérico L&P submetidos a manejo expectante por 6 meses após o esvaziamento uterino, de 1992 a 2010; Grupo de Estudo (SG): de 2011 a 2017, 32 pacientes em condições semelhantes de hCG receberam Vit-A na dose de 200.000 IU por dia, do momento da identificação do hCG em platô ate o primeiro hCG normal ou diagnóstico de progressão para neoplasia trofoblástica gestacional (NTG). O presente estudo foi aprovado pelo Comitê de Ética da Instituição na qual foi desenvolvido. RESULTADOS: Em ambos os grupos, a prevalência de hCG L&P foi < 5%. No SG, os níveis de hCG em platô foram maiores (CG = 85.5 versus SG = 195 IU/L; p = 0,028), e foram significantemente menores tanto a prevalência de NTG pós-molar (CG = 29.4% versus SG = 6.3%, p = 0,034) como o tempo de seguimento (CG = 14 versus SG = 10 meses, p < 0.001). Na evolução para NTG não houve diferença no estadiamento da International Federation of Gynecology and Obstetrics (FIGO, na sigla em inglês) ou na agressividade do tratamento. Com altas doses de Vit-A não houve qualquer efeito tóxico relevante. Não houve casos de recidiva de NTG ou de óbito. CONCLUSãO: O uso limitado de altas doses de Vit-A parace ser seguro e apresenta efeitos significativos na evolução de pacientes em controle pós-molar com títulos de hCG sérico L&P, e pode diminuir o desenvolvimento de NTG pós-molar nessa população.

Evaluation of 25-hydroxy vitamin D3 levels in patients with a fibroid uterus.

A cross sectional study was done at Era's Lucknow Medical College & Hospital, Lucknowwith the objective to evaluate 25-hydroxyVitaminD3 level in women with and without uterine fibroid. Ninety subjects (45 cases and 45 controls) were enrolled. Cases were those having at least 1 uterine fibroid ≥10 mm detected on ultrasonography, while controls were those not having any uterine pathology. Estimation of Serum 25-hydroxyvitaminD3 Level was done. The mean ± SD concentration of 25-hydroxyvitaminD3 was Significantly lower in cases compared with controls (15.10 ± 6.09 vs 26.09 ± 7.90 respectively, p < 0.001).The number of women with 25-hydroxyvitaminD3 deficiency in cases and controls was 9(20%) and 3(6.67%) respectively (p < 0.001). Uterine fibroid size increased proportionately with decrease in 25-hydroxyvitaminD3 levels, (p = 0.014). We concluded that VitaminD3 deficiency is significantly associated with the occurrence of Uterine fibroids. Further studies need to be conducted in order to evaluate the therapeutic benefits VitaminD3 supplementation in the patients of Uterine fibroid.Impact Statementwhat is already known on this subject? Vitamin D is believed to regulate cell proliferation and differentiation, inhibit angiogenesis and stimulate apoptosis. Now a days hypovitaminosis D is believed to be a major risk factor in the development of uterine fibroids. There are several ideas about the use of vitamin D in uterine fibroid prevention or as a long term treatment but ongoing clinical trials in the area remain scarce.what do the results of this study add? Our study showed that 25-hydroxivitamin d3 deficiency is significantly associated with uterine fibroid.Lower levels of 25-hydroxivitamin d3were found to have aninverse relationship with increased size of fibroid uterus.what are the implications of these findings for clinical practice and / or further reasearch? Vitamin D seems to be a promising, safe and low-cost agent for the prevention and treatment of uterine fibroids. However, further studies with larger sample size are needed to confirm our findings.

An integrated serum and urinary metabonomic research of Rhizoma Curcumae-Rhizoma Sparganii drug pair in hysteromyoma rats based on UPLC-Q-TOF-MS analysis.

ETHNOPHARMACOLOGICAL RELEVANCE: Rhizoma Curcumae and Rhizoma Sparganii (RCRS), a celebrated traditional Chinese medicine drug pair, has been used to treat hysteromyoma (HY). AIM OF THE STUDY: We aimed to identify the endogenous biomarkers of RCRS against HY. MATERIALS AND METHODS: HY rat model was established by injecting intramuscularly estradiol benzoate and progesterone injection from inner thigh in sequence. Body weight, uterus morphological indexes, immunohistochemistry (IHC) and hematoxylin and eosin (HE) staining experiments were used to evaluate the efficacy of RCRS (The rats were treated with RCRS extract, which was made by soxhlet reflux method. The rats were administrated intragastrically with 2 mL of RCRS extract). UPLC-Q-TOF-MS based metabonomics was adopted to analyze the serum and urine biomarkers from HY rats before and after RCRS treatment. Principle component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) were utilized to identify differences of metabolic profiles in rats among the four groups. RESULTS: 16 potential biomarkers from serum and 18 potential biomarkers from urine in both positive and negative mass spectrometry detection modes were identified, primarily related to Linoleic acid metabolism and Glyoxylate and dicarboxylate metabolism. RCRS drug pair has therapeutic effects on rats with HY via the regulation of multiple metabolic pathways. CONCLUSIONS: This study provides a useful method to get insight into the integrated metabonomic mechanism of RCRS drug pair on HY rats.

Humoral Hypercalcemia in Uterine Cancers: A Case Report and Literature Review.

BACKGROUND Paraneoplastic hypercalcemia is a well-described complication associated with a variety of malignancies. However, its incidence in gynecological malignancies is low. CASE REPORT A 53-year-old woman presented with progressive abdominal distention and irregular vaginal bleeding of several weeks' duration. A contrast CT abdomen and pelvis was significant for a mass in the lower uterine/cervical region, multiple peritoneal and omental masses, enlarged pelvic and paraaortic lymph nodes, and large-volume ascites. A pelvic exam revealed a fungating vaginal mass, with biopsy showing a high-grade tumor with immunohistochemical staining positive for vimentin, CD10, and cyclin D1, consistent with endometrial stromal sarcoma. During her hospitalization, the patient became increasingly lethargic. Workup showed severe hypercalcemia and evidence of acute kidney injury. The patient did not have evidence of bony metastatic disease on imaging studies. Further laboratory evaluation revealed an elevated PTHrP of 301 pg/mL (nl 14-27), a depressed PTH level of 3 pg/mL (nl 15-65), and a depressed 25-OH vitamin D level of 16 ng/mL (nl 30-100), consistent with humoral hypercalcemia of malignancy. The patient was treated with pamidronate, calcitonin, and intravenous fluids. She eventually required temporary hemodialysis and denosumab for refractory hypercalcemia, which improved her electrolyte abnormalities and clinical status. CONCLUSIONS Uterine malignancies of various histologies are increasingly recognized as a cause of humoral hypercalcemia. They are an important differential diagnosis in a woman with hypercalcemia and abnormal vaginal bleeding or abdominal symptoms.

Is chemotherapy necessary for patients with molar pregnancy and human chorionic gonadotropin serum levels raised but falling at 6months after uterine evacuation?

OBJECTIVE: To compare the outcomes of Brazilian patients with molar pregnancy who continue human chorionic gonadotropin (hCG) surveillance with those treated with chemotherapy when hCG was still positive, but falling at 6months after uterine evacuation. METHODS: Retrospective chart review of 12,526 patients with hydatidiform mole treated at one of nine Brazilian reference centers from January 1990 to May 2016. RESULTS: At 6months from uterine evacuation, 96 (0.8%) patients had hCG levels raised but falling. In 15/96 (15.6%) patients, chemotherapy was initiated immediately per FIGO 2000 criteria, while 81/96 (84.4%) patients were managed expectantly. Among the latter, 65/81 (80.2%) achieved spontaneous remission and 16 (19.8%) developed postmolar gestational trophoblastic neoplasia (GTN). Patients who received chemotherapy following expectant management required more time for remission (11 versus 8months; p=0.001), had a greater interval between uterine evacuation and initiating chemotherapy (8 versus 6months; p<0.001), and presented with a median WHO/FIGO risk score higher than women treated according to FIGO 2000 criteria (4 versus 2, p=0.04), but there were no significant differences in the need for multiagent treatment regimens (1/15 versus 3/16 patients, p=0.60). None of the women relapsed, and no deaths occurred in either group. CONCLUSION: In order to avoid unnecessary exposure of women to chemotherapy, we no longer follow the FIGO 2000 recommendation to treat all patients with molar pregnancy and hCG raised but falling at 6months after evacuation. Instead, we pursue close hormonal and radiological surveillance as the best strategy for these patients.

[Effect of Guizhi Fuling capsule and combination of active ingredients on rats with uterine myoma].

It is to observe the therapeutic action of Guizhi Fuling capsule and the combination of active ingredients on model rats with uterine leiomyoma. The hysteromyoma rats models was established in rats by loading eatrogen, to observe the effect on pathological condition of uterus, uterus wet weight, the content of estradiol and progesterone. Guizhi Fuling capsule and the combination of active ingredients remarkably decreased uterus weight, restrained the excess proliferation of the smooth muscle of uterus, decreased the estraiol and progesterone in blood serum. Guizhi Fuling capsule and the combination of active ingredients can restrain the formation of hysteromyoma in a dose-dependent manner. Perhaps the combination of active ingredients is the material foundation of antihysteromyoma.

Vitamin D status in women with uterine leiomyomas.

CONTEXT: Recent in vitro and in vivo experimental evidence supports a role of vitamin D insufficiency as an important factor in the development of uterine leiomyomas. However, epidemiological data supporting this possibility are scanty. OBJECTIVE: Our objective was to investigate vitamin D status in women with and without uterine leiomyomas. DESIGN: This was a case-control study of women referring to 2 infertility units in Italy. Women were eligible as cases if they were diagnosed with at least 1 uterine leiomyoma with a mean diameter ≥10 mm at transvaginal ultrasound. Each of them was matched to the 2 subsequent women of the same age (±1 year) whose uterus resulted unremarkable at ultrasound. Selected women provided a blood sample for the quantitative detection of 25-hydroxyvitamin D3 levels. MAIN OUTCOME MEASURE: We measured serum concentration of 25-hydroxyvitamin D3. RESULTS: A total of 128 women with leiomyomas and 256 controls were selected. The mean ± SD serum concentration of 25-hydroxyvitamin D3 was significantly lower in affected women compared with controls (18.0 ± 7.7 vs 20.8 ± 11.1 ng/mL respectively, P = .010). The number (proportion) of women with 25-hydroxyvitamin D3 deficiency (ie, <10 ng/mL) in cases and controls was 19 (15%) and 19 (7%), respectively (P = .022). The adjusted odds ratio for the presence of leiomyomas in women with serum levels of 25-hydroxyvitamin D3 deficiency was 2.4 (95% confidence interval = 1.2-4.9) (P = .016). CONCLUSIONS: Vitamin D is an emerging regulator of uterine leiomyoma development. Cohort and interventional studies are pressingly needed to confirm a causal relationship and to investigate the potential therapeutic benefits of vitamin D supplementation.

Multicenter, phase 3 trial comparing selenium supplementation with observation in gynecologic radiation oncology.

PURPOSE: We assessed whether adjuvant supplementation with selenium improves the selenium status and reduces side effects of patients treated by radiotherapy (RT) for cervical and uterine cancer. METHODS AND MATERIALS: Whole-blood selenium concentrations were measured in patients with cervical cancer (n = 11) and uterine cancer (n = 70) after surgical treatment, during RT, at the end of RT, and 6 weeks after RT. Patients with initial selenium concentrations of less than 84µg/L were randomized before RT either to receive 500 µg of selenium (in the form of sodium selenite [selenase, biosyn Arzneimittel GmbH, Fellbach, Germany]) by mouth on the days of RT and 300 µg of selenium on the days without RT or to receive no supplement during RT. The primary endpoint of this multicenter Phase 3 study was to assess the efficiency of selenium supplementation during RT; the secondary endpoint was to decrease radiation-induced diarrhea and other RT-dependent side effects. RESULTS: A total of 81 patients were randomized. We enrolled 39 in the selenium group (SG) and 42 in the control group (CG). Selenium levels did not differ between the SG and CG upon study initiation but were significantly higher in the SG at the end of RT. The actuarial incidence of diarrhea of Grade 2 or higher according to Common Toxicity Criteria (version 2) in the SG was 20.5% compared with 44.5% in the CG (p = 0.04). Other blood parameters, Eastern Cooperative Oncology Group performance status, and self-reported quality of life were not different between the groups. CONCLUSIONS: Selenium supplementation during RT is effective in improving blood selenium status in selenium-deficient cervical and uterine cancer patients and reduces the number of episodes and severity of RT-induced diarrhea.

Dietary tomato powder supplementation in the prevention of leiomyoma of the oviduct in the Japanese quail.

Spontaneous leiomyomas of the oviduct are common tumors of the Japanese Quail (Coturnix coturnix japonica), which makes it a good animal model for screening potential agents for testing in the prevention and treatment of human myoma uteri. We have previously reported a decreased incidence of leiomyomas in the oviduct of Japanese quail with lycopene supplementation. Although the major carotenoid in tomatoes is lycopene, tomatoes also contain other compounds, which may contribute to their health benefit. Therefore, in this study, we investigated the effects of tomato powder supplementation on the development of leiomyomas in the oviduct of Japanese quail. We also measured serum levels of malondialdehyde (MDA), carotenoids, and vitamins C, E, and A. A total of 150 quails (3 mo old) were assigned to 3 treatment groups consisting of 5 replicates of 10 birds in each group. Birds were fed either a basal diet (control group) or the basal diet supplemented with 25 g (Treatment I) or 50 g (Treatment II) of tomato powder (0.8 mg lycopene per g of tomato powder) per kg of diet. The animals were sacrificed after 365 days, and the tumors were identified. Tomato powder supplementation significantly decreased the number of leiomyomas as compared to control birds (P < 0.01). The tumors in tomato powder fed birds were smaller than those found in control birds (P < 0.01). Serum lycopene, lutein, zeaxantin, and vitamins C, E, and A increased (P = 0.01), whereas MDA concentrations decreased (P = 0.01) with tomato powder supplementation. No measurable lycopene could be detected in the serum of control birds, whereas a dose-dependent increase was observed in the serum of birds supplemented with tomato powder. The results indicate that dietary supplementation with tomato powder reduces the incidence and size of spontaneously occurring leiomyoma of the oviduct in the Japanese quail. Clinical trials should be conducted to investigate the efficacy of tomato powder supplementation in the prevention and treatment of uterine leiomyoma in humans.

[Improvement effects of Jincao tablet on immune function of model of hysteromyoma in rats].

OBJECTIVE: To investigate the improvement effects of Jincao tablet on immune function of the model of hysteromyoma in rat and the relationship between the model and pathogenesis. METHOD: Rats were randomly divided into 6 groups: normal group, model group, treatment groups including low,middle and high dosage groups of Jincao tablet and Guizhi Fuling pill. Rats were injected respectively with diethyl stilbestrol and progesterone. The immune apparatus of rats were measured. The levels of CD3, CD4 and CD4/ CD8 in serum were determined by flow cytometer. The estrogen and receptor were measured by radioligand binding assay and pathologic changes of womb tissue were observed microscopically. RESULT: Compared with normal group, the weight of thymus, the levels of CD3, CD4 and CD4/CD8 of model group were significantly decreased, and the levels of estrogen, estrogen receptor and CD8 were obviously increased. Jincao tablet groups were significant difference compared with model group and could alleviate the pathological changes of womb tissue. CONCLUSION: Jincao tablet could improve the levels of immune function of the model of hysteromyoma in rat, and it might play a role in the pathogenesis of leiomyoma.

[Manganese and selenium content in plasma of women with uterine myoma].

OBJECTIVE OF THE STUDY: To determine plasma concentration of manganese and selenium in women with uterine fibroids. MATERIALS AND METHODS: The study included 22 women with uterine fibroids (group A) and a control group of 25 women (group B). Flame atomic-absorbable spectrometry was used for the purpose of the study. The patients were admitted in the Clinic of Gynaecology of UMPHAT "Dr. G. Stransky" in the period 01.01.2007-01.07.2007. RESULTS AND DISCUSSION: No significant difference was found between the plasma concentrations of manganese in group A and B. Selenium plasma concentration of group A was determined as significantly lower in comparison with that of group B. The obtained results can serve as a precondition for investigations on a larger scale.

Early identification of resistance to first-line single-agent methotrexate in patients with persistent trophoblastic disease.

PURPOSE: A generally accepted definition for resistance to first-line single-agent chemotherapy for persistent trophoblastic disease (PTD) is lacking. In the present study, a normogram for serum human chorionic gonadotropin (hCG) from patients with normalization of serum hCG after first-line single-agent chemotherapy for PTD was constructed to identify patients resistant to this chemotherapy. PATIENTS AND METHODS: Between 1987 and 2004, data from 2,132 patients were registered at the Dutch Central Registry for Hydatidiform Moles. A normal serum hCG regression corridor was constructed for 79 patients with low-risk PTD who were cured by single-agent methotrexate (MTX) chemotherapy (control group). Another group of 29 patients with low-risk PTD needed additional alternative therapies (dactinomycin and multiagent chemotherapy) for failure of serum hCG to normalize with single-agent chemotherapy (study group). RESULTS: Serum hCG measurement preceding the fourth and sixth single-agent chemotherapy course proved to have excellent diagnostic accuracy for identifying resistance to single-agent chemotherapy, with an area under the curve (AUC) for receiver operating characteristic curve analysis of 0.949 and 0.975, respectively. At 97.5% specificity, serum hCG measurements after 7 weeks showed 50% sensitivity. CONCLUSION: In the largest study to date, we describe the regression of serum hCG levels in patients with low-risk PTD successfully treated with MTX. At high specificity, hCG levels in the first few courses of MTX can identify half the number of patients who are extremely likely to need alternative chemotherapy to cure their disease and for whom further treatment with single-agent chemotherapy will be ineffective.

[Clinical study on effect of Tripterygium wilfordii Hook. f. on uterin leiomyoma].

OBJECTIVE: To observe the therapeutic effect of Tripterygium wilfordii Hook. f. on patients with uterine leiomyoma. METHODS: Baseline ultrasound examinations of myomas and uterine were obtained and repeated three months, six months after treatment. Blood samples were collected in the mid-follicular or mid-luteal phase of the menstrual cycle before initiation of Tripterygium wilfordii Hook. f. therapy and after treatment 3-4 months and 5-6 months, for determination of estradiol, progesteron, testosterone, follicle-stimulating hormone, luteinizing hormone and prolactin by radioimmunoassay. RESULTS: Significant decrease in leiomyoma volume was detected in 39 of 65 (60.0%) patients after 3-4 months of Tripterygium wilfordii Hook. f. treatment and 28 of 40 (70.0%) patients after 5-6 months of treatment. The decrease in leiomyoma volume with Tripterygium wilfordii Hook. f. treatment was time-dependent while 27.84% in 3-4 months, 51.6% in 5-6 months. 25 of 65 patients were amenorrheic during the course of treatment. Compared with pretreatment values, Tripterygium wilfordii Hook. f. treatment induced an increase in mean luteinizing hormone, fdlicle-stimulating hormone levels and a decrease in mean estradiol, progesterone levels. CONCLUSIONS: Tripterygium wilfordii Hook. f. may be an effective therapeutic agent for leiomyomas with fewer side effects. Tripterygium wilfordii Hook. f. treatment showed a reversibly inhibitory effect on the ovary. It may be one of the mechanisms of Tripterygium wilfordii Hook. f. in decreasing leiomyoma volume.

Conservative management for perimenopausal women with uterine leiomyomas using Chinese herbal medicines and synthetic analogs of gonadotropin-releasing hormone.

The effects of a long-term intranasal administration of each of the gonadotropin-releasing hormone analogs, buserelin and nafarelin on uterine leiomyomas after conservative treatment using Chinese herbal medicines, Keishi-bukuryo-gan and Shakuyaku-kanzo-to were investigated in 30 perimenopausal women with leiomyomas. Hypermenorrhea and/or dysmenorrhea as a chief complaint was moderately improved by the treatment using Chinese herbal medicines in more than 60% of the patients with less than fist-sized leiomyomas, but not the over fist-sized. Afterwards, continuous treatment using analogs produced a long-term reduction in leiomyomas (less than 60%) along with decreases in the serum levels of luteinizing hormone, follicle-stimulating hormone, estradiol, and the tumor marker CA-125, and adverse effects including slight boneloss. Long-term treatment using Chinese herbal medicines and gonadotropin-releasing hormone analogs for the management of uterine leiomyomas could be beneficial for patients a few years before menopause, though possible side effects of this treatment should be monitored.

[Differed autologous blood transfusion in the "G" point hospital in Bamako. Prospective study apropos of 40 cases]. / Transfusion autologue différée à l'hôpital du point "G" à Bamako. Etude prospective portant sur 40 observations.

With a sample of 40 patients, the authors conducted a prospective case-control study on the feasibility of differed autologous blood transfusion at Point "G" National Hospital in Bamako, Mali. The method has been accepted by all the patients. No clinical nor biological trouble has been reported by the patients themselves. The authors recommend the use of autologous blood transfusion by other hospital units and the development of regulations governing its implementation.

High-dose methotrexate for gestational trophoblastic disease.

Eighty patients with low-risk and 5 patients with intermediate-risk gestational trophoblastic neoplasia (GTN) (WHO classification) were treated with single-agent high-dose methotrexate with folinic acid rescue (MTX/FAR). By the NCI classification, 65 patients had nonmetastatic GTN, 13 patients had low-risk metastatic GTN, and 7 patients had high-risk metastatic GTN. Seventy-one (84%) patients achieved remission (beta HCG < or = 5 IU/liter) with MTX/FAR, whereas 14 (16%) failed to achieve remission with MTX/FAR alone. All failures were salvaged with second-line therapies. Patients successfully treated with MTX/FAR required a median of 4 courses to achieve remission, and a median of 2 consolidative courses. Factors found predictive of failure with MTX/FAR were pretreatment beta HCG (P = 0.003), prior history of GTN (P < 0.04), and time from termination of antecedent pregnancy to initiation of treatment (P < 0.05). No significant difference was noted between the "success" and "failure" groups with respect to MTX dose or infusion time, the timing and dosage of folinic acid rescue, the number of courses of MTX, or the mean interval between courses. Multivariate analysis revealed that the pretreatment beta HCG (P < 0.01) and short time from termination of antecedent pregnancy to initiation of treatment (P < 0.03) were independently significant for failure. No significant (grade 3/4) hematologic or gastrointestinal toxicity occurred, and no treatment delays or dose reductions were required. This regimen is both effective and well tolerated; however, the theoretical advantages of high-dose methotrexate do not appear to offer any clinical advantage over conventional dose MTX in low- and intermediate-risk GTN.
