Neutrophil to lymphocyte ratio as an assessment tool to differentiate between uterine sarcoma and myoma: a systematic review and meta-analysis.

BACKGROUND: This systematic review and meta-analysis aimed to determine the potential value of neutrophil to lymphocyte ratio (NLR) as an assessment tool in the clinical distinction between uterine sarcoma and uterine leiomyoma. METHODS: We comprehensively searched Web of Science, Scopus, and PubMed for relevant papers published before March 19, 2023. The standardized mean difference (SMD) was provided, along with a 95% confidence interval (CI). The random-effects model was employed to derive pooled effects due to the high levels of heterogeneity. The Newcastle-Ottawa scale was used for the quality assessment. Our study was registered in PROSPERO (CRD42023478331). RESULTS: Overall, seven articles were included in the analysis. A random-effect model revealed that patients with uterine sarcoma had higher NLR levels compared to those with uterine myoma (SMD = 0.60, 95% CI = 0.22-0.98; p = 0.002). In the subgroup analysis according to sample size, we found that patients with uterine sarcoma had elevated levels of NLR compared to those with uterine myoma in either large studies (SMD = 0.58, 95% CI = 0.04-1.13; P < 0.001) or small studies (SMD = 0.64, 95% CI = 0.33-0.96; P = 0.32). In the sensitivity analysis, we found that the final result was not significantly changed when single studies were removed, suggesting that the finding of this meta-analysis was stable. The pooled sensitivity of NLR was 0.68 (95% CI = 0.61-0.73), and the pooled specificity was 0.64 (95% CI = 0.59-0.69). CONCLUSION: NLR might be utilized as an assessment tool in clinics to help clinicians differentiate between patients with uterine sarcoma and those with myoma.

High negative prediction for the Basel sarcoma score: Sonographic assessment of features suspicious of uterine sarcoma.

INTRODUCTION: In the management of uterine myomas, laparoscopic surgery with morcellation enables a minimal invasive procedure. Cases of unsuspected uterine sarcoma dissemination have been reported and led to regulative restrictions. To help to distinguish preoperatively myomas from sarcomas, we assessed the value of six sonographic criteria (Basel Sarcoma Score, BSS) in a prospective outpatient cohort of consecutive patients with uterine masses. MATERIAL AND METHODS: We prospectively evaluated all patients presenting with myoma-like masses planned for surgery with standardized ultrasound examination. BSS including the following criteria was investigated: rapid growth in past three months, high blood flow, atypical growth, irregular lining, central necrosis and oval solitary lesion. For each criterion, a score 0/1 was given. BSS (0-6) equals the sum of all given scores. Histological diagnosis was used as reference. RESULTS: Among 545 patients, 522 had the final diagnosis of myoma, 16 had peritoneal masses with sarcomatous components (PMSC), and seven had other malignancies. Median BSS for PMSC was 2.5 (range: 0-4) vs 0 for myomas (range: 0-3). The most common sonographic criteria leading to a false positive score in myomas were rapid growth in past three months and high blood flow. For the detection of sarcomatous masses with BSS threshold of >1, sensitivity was 93.8%, specificity 97.9%, and positive predictive value (PPV) and negative predictive value (NPV) were 57.7% and 99.8%, respectively (AUC 0.95). CONCLUSION: BSS can help distinguishing between myomas and sarcomatous masses, with high NPV. Caution is required when >1 criterion is present. As a simple tool, it could easily be integrated into routine myoma sonographic examination and help develop standardized assessment of uterine masses for better preoperative triage.

Rates of Complications and Reoperation after Myomectomy-the Impact of Surgical Approach: A Statewide Population-based Cohort Study from 2005-2018.

STUDY OBJECTIVE: To assess rates of and factors associated with complications and reoperation after myomectomy. DESIGN: Population-based cohort study. SETTING: All non-Veterans Affairs facilities in the state of California from January 1, 2005, to December 31, 2018. PARTICIPANTS: Women undergoing abdominal or laparoscopic myomectomy for myoma disease were identified from the Office of Statewide Health Planning and Development datasets using appropriate International Classification of Diseases, Ninth and Tenth Revision and Current Procedural Terminology codes. INTERVENTIONS: Demographics, surgery facility type, facility surgical volume, and surgical approach were identified. Primary outcomes included complications occurring within 60 days of surgery and reoperations for myomas. Patients were followed up for over an average of 7.3 years. Univariate and multivariable associations were explored between the above factors and rates of complications and reoperation. All odds ratios (ORs) are adjusted ORs. MEASUREMENTS AND MAIN RESULTS: Of the 66 012 patients undergoing myomectomy, 5265 had at least one complication (8.0%). Advanced age, black, Asian race, MediCal and Medicare payor status, academic facility, and medical comorbidities were associated with increased odds of a complication. Minimally invasive myomectomy (MIM) was associated with decreased complications compared with abdominal myomectomy (AM) (OR, 0.29; 95% confidence interval [CI], 0.25-0.33; p <.001). Overall, 17 377 patients (26.3%) underwent reoperation. Medicare and MediCal payor status and medical comorbidities were associated with increased odds of a repeat surgery. Reoperation rates were higher in the MIM group over the entire study period (OR, 2.33; 95% CI, 1.95-2.79; p <.001). However, the odds of reoperation after MIM decreased each year (OR, 0.93; 95% CI 0.92-0.95; p <.001), with the odds of reoperation after AM surpassing MIM in 2015. CONCLUSION: This study identifies outcome disparities in the surgical management of myomas and describes important differences in the rates of complications and reoperations, which can be used to counsel patients on surgical approach. These findings suggest that MIM can be considered a lasting and safe approach in properly selected patients.

Influência da posição sócio-econômica ao longo da vida nas desigualdades de cor/raça na ocorrência de miomas uterinos: estudo pró- saúde / Influence of socioeconomic position lifelong inequalities in color / race in the occurrence of uterine fibroids: pro-health study

Os miomas uterinos (MU) são considerados os tumores mais comuns dosistema reprodutor feminino. Estudos norte-americanos demonstram que mulheres negras são mais acometidas pelos MU que as de outros grupos étnico-raciais. No entanto, as causas da desigualdade racial na ocorrência dos tumores permanecem desconhecidas e possíveis mecanismos são pouco explorados na literatura. Em outra direção, devido às características dos MU (crescimento lento e longo períodode latência) parte considerável dos estudos epidemiológicos utilizam umdelineamento transversal, o que pode gerar problemas metodológicos, como osrelacionados à utilização da idade coletada transversalmente (posteriormente a ocorrência dos MU) como proxy da idade do surgimento dos tumores. Assim, este trabalho de tese foi dividido em três partes, como se segue. A primeira, com características descritivas, teve por objetivo estimar a ocorrência de MU autorelatadossegundo categorias demográficas e sócio-econômicas na população deestudo (compôs o artigo 1). A segunda, com componente analítico, propôs-se aavaliar o papel da PSE ao longo da vida como mediadora do efeito da cor/raça naocorrência de MU auto-relatados (compôs o artigo 2). A terceira, com caráter metodológico, teve por objetivo comparar medidas de associação, entre variáveis aferidas transversalmente, em análises que incluem a co-variável idade no momento da coleta de dados e análises que consideram a idade ao diagnóstico dos MU (compôs o artigo 3). Para tanto, foram analisados dados transversais da população feminina participante das duas etapas da linha de base do Estudo Pró-Saúde, referentes à história auto-relatada de diagnóstico médico de MU e ainda a características sócio-demográficas, da vida reprodutiva e de acesso a serviços de saúde...

Clinical assessment for three routes of hysterectomy.

BACKGROUND: Hysterectomy is a very common surgery in gynecology. Ideal surgery for hysterectomy is microinvasive with few complications. There are three major routes of hysterectomy that are currently used. The aim of this study was to identify the differences of peri-operative outcome among the patients who underwent the three different approaches. METHODS: One hundred and one women undergoing hysterectomy for myoma had the procedure performed by laparoscopic assisted vaginal hysterectomy (LAVH), total vaginal hysterectomy (TVH) or total abdominal hysterectomy (TAH) in a randomized study. We compared the course of peri-operative and post-operative outcome for the three different approaches. RESULTS: were evaluated by linear regression analysis, Fisher's exact test and Student's t test for independent samples. RESULTS: The operation time among the three procedures was not significantly different (P > 0.05). The amount of blood loss in the TVH group was less than in the LAVH and TAH groups (P < 0.05). The pain score 3 hours after operation in the LAVH group was significantly lower than in the TAH and TVH groups (P < 0.001). The pain scores in the LAVH and TVH groups were lower than in the TAH group at 24 and 48 hours after operation (P < 0.01). The women who underwent LAVH and TVH had a shorter hospitalization stay (P < 0.001). The highest body temperature after operation in the TAH group was higher than that in LAVH and TVH groups (P < 0.001). CONCLUSIONS: LAVH and TVH are better procedures for women requiring hysterectomy. The peri-operative and post-operative courses of TVH are better than LAVH, excluding the pain score 3 hours after operation. Vaginal hysterectomy is the most cost-effective approach but the final choice for the route of hysterectomy can depend on many factors such as gynecological disease, patients' health status and experiences of the gynecologist.

[Assessment of different homeostatic methods used in laparoscopic intramural myomectomy].

OBJECTIVE: To explore the safe and effective method of hemostasis in laparoscopic hysteromyomectomy (LM). METHODS: Two hundred and eighty women with symptomatic uterine intramural fibroids undergoing LM were assigned to 4 groups, Group A undergoing fibroid pedicle ligation, Group B injected with 12 IU diluted vasopressin around the myoma, Group C injected with 20 IU oxytocin combined with pedicle ligation, and Group D injected with vasopressin combined with pedicle ligation. The operation time, amount of blood loss, operative complications, bowel deflation, post-operative hemoglobin dropping, and length of hospital stay were compared. RESULTS: The amounts of blood loss of Groups A and C were (171 +/- 146) ml and (184 +/- 140) ml, both significantly higher than those of Groups B and D [(115 +/- 70) ml and (106 +/- 73) ml, both P < 0.01]. The length of hospital stay of Group D was (2.9 +/- 0.5) d, significantly shorter than those of Groups A, B, and C [(3.1 +/- 0.7) d, (3.6 +/- 0.8) d, and (3.3 +/- 0.7) d, all P < 0.05]. The bowel deflation time of Group D was (20 +/- 6) h, significantly shorter than those of the Groups A, B, and C [(26 +/-) h, (25 +/- 7) h, and (25 +/- 8) h respectively, all P < 0.05]. The post-operative hemoglobin dropping of group D was (1.1 +/- 0.9) g/L, significantly less than those of Groups A, B, and C [(1.5 +/- 1.0), (1.4 +/- 0.8), and (1.2 +/- 0.7) g/L respectively, all P < 0.05]. CONCLUSIONS: Vasopressin (12 IU) injection around the myoma is a simple, effective, and safe homeostatic procedure during LM. Pedicle ligation can reduce advanced post-operative bleeding post-operation.

Treatment patterns for women with new episodes of uterine myomas in an insured population in the US.

INTRODUCTION: Uterine myomas are the most common benign tumors in reproductive-aged women and a leading reason for gynecologist visits and hysterectomies in the United States. This study examines the treatment patterns of insured women with new episodes of uterine myomas. MATERIALS AND METHODS: We used administrative claims from a proprietary research database to evaluate services (inpatient, outpatient, and prescription claims) incurred from January 1, 2001 to December 31, 2003. We identified women with CPT or ICD-9-CM codes suggestive of myoma and described treatment patterns for all women with a new episode of myoma and those with abnormal bleeding. RESULTS: The primary study group included 35 329 women with new episodes of care and at least three months of data before and after their index date for myoma. Most women (82.9%) had no code for diagnostic testing in the three months before or after the first myoma marker. Of 14 434 women with one year of follow-up, 26.1% had surgery and 24.7% were treated pharmacologically (oral contraceptives, progestins, or gonadotropin-releasing hormone agonists). Over half (55.1%) of women were untreated, including 45% of those with an ICD-9 code that indicated abnormal bleeding. CONCLUSIONS: Women with new myoma episodes rarely had codes for confirmatory diagnostic tests. Many women with myomas go untreated for at least a year. This is true even for those with evidence of abnormal bleeding. Myoma care may be improved through the introduction of new, safe, and effective therapies.

Medico-economic approach to the management of uterine myomas: a 6-month cost-effectiveness study of pelvic embolization versus vaginal hysterectomy.

INTRODUCTION: Uterine artery embolization is a technique that has been recently proposed for the management of uterine myomas an alternative to vaginal hysterectomy. The results provided by the first published studies demonstrate a significant decrease in symptoms in 70-95% of cases. The aim of our study was to compare the cost-effectiveness ratios for pelvic embolization and vaginal hysterectomy looked at from the hospital point of view. MATERIALS AND METHODS: Two populations of patients were randomly selected from women undergoing pelvic embolization or vaginal hysterectomy. We retrospectively measured the cost at 6 months of the two types of procedure (costs of hospitalization, drugs, and complementary examinations) as well as the success of each of them at 6 months. The cost of the techniques themselves were measured prospectively on the basis of four procedures. RESULTS: The cost-effectiveness ratios were 2320 Euros per success (mean cost 2134 Euros per effectiveness 92%) for embolization and 2789 Euros per success (mean cost 2789 Euros per effectiveness 100%) for hysterectomy. DISCUSSION: Pelvic embolization is more cost-effective than vaginal hysterectomy. The integration of the notion of quality of life with the notion of cost should permit a future study to reinforce interest in performing pelvic embolizations in the management of uterine myomas.

Clinical utility of saline solution infusion sonohysterography in a primary care obstetric-gynecologic practice.

OBJECTIVE: The purpose of this study was to evaluate the role of saline solution infusion sonohysterography in clinical practice in patients with abnormal uterine bleeding. STUDY DESIGN: A prospective case-controlled study was conducted comparing two-dimensional transvaginal imaging with saline solution infusion sonohysterography, endometrial biopsies, and histologic evaluation after surgical procedures. One hundred twenty-four patients with abnormal uterine bleeding were scanned transabdominally and transvaginally. Patients with an increased endometrial thickness or a poorly defined endometrium underwent saline solution infusion sonohysterography. Sterile saline solution, 4 to 10 ml, was injected into the endometrial cavity under direct ultrasonographic visualization. Once the endometrium was expanded, the presence of polyps or myomas and the anterior and posterior endometrial thickness was assessed. RESULTS: Fifty-six patients were noted to have uterine leiomyomas. Eighteen patients had endometrial polyps. Five patients had simple endometrial hyperplasia. Two patients had atypical hyperplasia. No patients in this study had endometrial cancer. No complications occurred in this group of patients. CONCLUSION: Saline solution infusion sonohysterography is a procedure that aids the clinician in the management of abnormal uterine bleeding and may be more cost effective than traditional methods of evaluation.

Socioeconomic variations in hysterectomy: evidence from a linkage study of the Finnish hospital discharge register and population census.

STUDY OBJECTIVE: To explore variations in rates for hysterectomy in relation to social class, education, and family income. DESIGN: Retrospective analysis of the 1988 Finnish hospital discharge register linked individually to the 1987 population census. SETTING: Finland. PARTICIPANTS: All women living in Finland aged 35 and over were the denominator population. The numerators were the 8663 women who underwent hysterectomy in 1988. MAIN RESULTS: The overall rate for hysterectomy was 63.5/10,000 women aged 35 and over. There was a marked positive correlation between disposable family income and hysterectomy rates even after age, hospital catchment area, education, and occupational status were adjusted for. However, no linear trend for overall hysterectomy rates was observed in relation to social class or education. Procedures due to myomas, accounting for 48% of all hysterectomies, were more frequent among women of high socioeconomic status according to all socioeconomic indicators. Larger proportions of hysterectomies for myoma were also performed in patients in private hospitals and in pay beds in public hospitals than in women in worse off groups. CONCLUSIONS: Unlike the findings in earlier studies from other countries, there was a positive correlation between income and hysterectomy rates as a result of the high numbers of hysterectomies performed to treat myoma in the well off women. The findings are discussed in terms of socioeconomic differences in the use of private gynaecological services, and factors, such as parity and use of hormonal replacement therapy, that affect the growth of myomas.

Laparoscopy.

PIP: Laproscopic sterilization techniques and the diagnostic use of laparoscopy are discussed. In a series of 1000 laparoscopic sterilizations by the 2-incision technique, there was a total failure rate, surgical and operative, of .4%. In a similar series with the 1-incision technique and electrocagulation only, the total failure rate was 1.6%, though the complication rate was considerably reduced. The high failure rate was attributed to incomplete transection resulting in recanalization. The failure rate with a single-incision, 3-burn technique was .25% in a series of 2000 patients, and complications were few. Tubal occlusion with hemoclips has produced poor results (failure rate: 8-27%). The results with silastic bands, however, have been comparable to those for electrocoagulation, but with fewer complications. Means by which the cost of laparoscopic equipment may be reduced are discussed. Laparoscopy can be helpful in the diagnosis of infertility-endocrinology, ectopic pregnancy, pelvic pain, pelvic inflammatory disease, adnexal masses, and the retrieval of foreign bodies in the pelvic region. Contraindications to laparoscopy are reviewed. It is concluded that laparoscopy is a safe and effective means of sterilization on an outpatient basis, and is of value in the diagnosis of gynecologic disorders.^ieng

Embolização de mioma uterino

A embolização é um procedimento relativamente novo em medicina, vem sendo praticado desde 1995. Ele consiste em obstruir o fluxo sangüíneo. Uma das suas aplicações mais utilizadas é para o tratamento de mioma uterino. Um cateter é introduzido através de uma pequena incisão na altura da virilha e guiado pela artéria femural até a artéria uterina, na região do mioma. As embosferas são injetadas e o fluxo de sangue para o mioma é interrompido, fazendo com que ele reduza de tamanho progressivamente e morra.
