Combined Laparoscopic Uterine Artery Occlusion and Myomectomy versus Laparoscopic Myomectomy: A Direct-Comparison Meta-Analysis of Short- and Long-Term Outcomes in Women with Symptomatic Leiomyomas

OBJECTIVE

To ascertain the efficacy and safety of laparoscopic uterine artery occlusion (LUAO) during laparoscopic myomectomy (LM) on intra- and postoperative morbidity and to assess its impact on leiomyoma recurrence rates.

DATA SOURCES

MEDLINE, Scopus, Web of Science, and Cochrane Database were searched for relevant references from inception until December 2018, in line with PRISMA guidelines.

METHODS OF STUDY SELECTION

Two authors screened for study eligibility and extracted data. Randomized controlled trials (RCTs) and observational studies (OSs) comparing short- and long-term morbidity of LM with or without LUAO were included. The modified Jadad score and the methodologic index for nonrandomized studies were used to evaluate the quality of RCTs and OSs, respectively.

TABULATION, INTEGRATION, AND RESULTS

Twelve studies encompassing 750 LM and 873 LUAO-LM cases were included in the meta-analysis. The studies were of moderate quality. LUAO-LM appears to significantly decrease intraoperative blood loss, postoperative hemoglobin drop, and blood transfusion rate. A trend toward shorter hospital length of stay was demonstrated, whereas no significant difference in operation duration was observed. The combined procedure seemingly contributes to lower recurrence rate. No LUAO-related complications were reported. Moderate to high heterogeneity was observed for few outcomes.

CONCLUSION

This is the first meta-analysis to date to provide a convincing overview of efficacy and safety of LUAO-LM. Although a medium risk of bias warrants some caution with interpretation of the results, LUAO-LM seemingly improves intra- and postoperative outcomes in women with symptomatic leiomyomas.

First-line chemotherapy in low-risk gestational trophoblastic neoplasia

BACKGROUND

This is the second update of a Cochrane review that was first published in 2009, Issue 1, . Gestational trophoblastic neoplasia (GTN) is a rare but curable disease arising in the fetal chorion during pregnancy. Most women with low-risk GTN will be cured by evacuation of the uterus with or without single-agent chemotherapy. However, chemotherapy regimens vary between treatment centres worldwide and the comparable benefits and risks of these different regimens are unclear.

OBJECTIVES

To determine the efficacy and safety of first-line chemotherapy in the treatment of low-risk GTN.

SEARCH METHODS

We electronically searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and Embase in September 2008, February 2012, and January 2016. In addition, we searched online trial registers for protocols and ongoing trials.

SELECTION CRITERIA

For the original review, we included randomised controlled trials (RCTs), quasi-RCTs and non-RCTs that compared first-line chemotherapy for the treatment of low-risk GTN. For this updated versions of the review, we included only RCTs.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies for inclusion and extracted data to a pre-designed data extraction form. Meta-analysis was performed using the random-effects model.

MAIN RESULTS

We included seven RCTs (667 women) in this updated review. Most studies were at a low or moderate risk of bias and all compared methotrexate with actinomycin D. Three studies compared weekly intramuscular (IM) methotrexate with bi-weekly pulsed intravenous (IV) actinomycin D (393 women), one study compared five-day IM methotrexate with bi-weekly pulsed IV actinomycin D (75 women), one study compared eight-day IM methotrexate-folinic acid (MTX-FA) with five-day IV actinomycin D (49 women), and one study compared eight-day IM MTX-FA with bi-weekly pulsed IV actinomycin D. One study contributed no data. Moderate-certainty evidence indicates that actinomycin D is probably more likely to lead to primary cure than methotrexate (risk ratio (RR) 0.65, 95% confidence interval (CI) 0.57 to 0.75; six trials, 577 participants; I(2) = 26%), and first-line methotrexate treatment is probably more likely to fail than actinomycin D treatment (RR 3.55, 95% CI 1.81 to 6.95; six trials, 577 participants; I(2) = 61%; moderate-certainty evidence) Low-certainty evidence suggests that there may be little or no difference between methotrexate and actinomycin D treatment with respect to nausea (four studies, 466 women; RR 0.61, 95% CI 0.29 to 1.26) or any of the other individual side-effects reported, although data for all of these outcomes were insufficient and too inconsistent to be conclusive. Low-certainty evidence suggests that there may be little or no difference in the risk of severe adverse events (SAEs) between the groups overall (five studies, 515 women; RR 0.35, 95% CI 0.08 to 1.66; I² = 60%); however, the direction of effect favours methotrexate and more evidence is needed. Furthermore, evidence from subgroup analyses suggests that actinomycin D may be associated with a greater risk of SAEs than methotrexate (low-certainty evidence). We found no evidence on the effect of these treatments on future fertility.

AUTHORS' CONCLUSIONS

Actinomycin D is probably more likely to achieve a primary cure in women with low-risk GTN, and less likely to result in treatment failure, than a methotrexate regimen. There may be little or no difference between the pulsed actinomycin D regimen and the methotrexate regimen with regard to side-effects. However, actinomycin D may be associated with a greater risk of severe adverse events (SAEs) than a methotrexate regimen. Higher-certainty evidence is still needed on treating low-risk GTN and the four ongoing trials are likely to make a significant contribution to this field. Given the variety of treatment regimens, findings from these trials could facilitate a network meta-analysis in the next version of this review to help women and clinicians determine the best treatment options for low-risk GTN.

Chemotherapy for resistant or recurrent gestational trophoblastic neoplasia

BACKGROUND

Gestational trophoblastic neoplasia (GTN) is a highly curable group of pregnancy-related tumours; however, approximately 25% of GTN tumours will be resistant to, or will relapse after, initial chemotherapy. These resistant and relapsed lesions will require salvage chemotherapy with or without surgery. Various salvage regimens are used worldwide. It is unclear which regimens are the most effective and the least toxic.

OBJECTIVES

To determine which chemotherapy regimen/s for the treatment of resistant or relapsed GTN is/are the most effective and the least toxic.

SEARCH METHODS

We searched the Cochrane Gynaecological Cancer Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 4), MEDLINE and EMBASE up to October 2011. In addition, we handsearched the relevant society conference proceedings and study reference lists. For the updated review, we searched Cochrane Group Specialised Register, CENTRAL, MEDLINE and EMBASE to 16 Novemeber 2015. In addition, we searched online clinical trial registries for ongoing trials.

SELECTION CRITERIA

Only randomised controlled trials (RCTs) were included.

DATA COLLECTION AND ANALYSIS

We designed a data extraction form and planned to use random-effects methods in Review Manager 5.1 for meta-analyses.

MAIN RESULTS

The search identified no RCTs; therefore we were unable to perform any meta-analyses.

AUTHORS' CONCLUSIONS

RCTs in GTN are scarce owing to the low prevalence of this disease and its highly chemosensitive nature. As chemotherapeutic agents may be associated with substantial side effects, the ideal treatment should achieve maximum efficacy with minimal side effects. For methotrexate-resistant or recurrent low-risk GTN, a common practice is to use sequential five-day dactinomycin, followed by MAC (methotrexate, dactinomycin, cyclophosphamide) or EMA/CO (etoposide, methotrexate, dactinomycin, cyclophosphamide, vinblastine) if further salvage therapy is required. However, five-day dactinomycin is associated with more side effects than pulsed dactinomycin, therefore an RCT comparing the relative efficacy and safety of these two regimens in the context of failed primary methotrexate treatment is desirable.For high-risk GTN, EMA/CO is the most commonly used first-line therapy, with platinum-etoposide combinations, particularly EMA/EP (etoposide, methotrexate, dactinomycin/etoposide, cisplatin), being favoured as salvage therapy. Alternatives, including TP/TE (paclitaxel, cisplatin/ paclitaxel, etoposide), BEP (bleomycin, etoposide, cisplatin), FAEV (floxuridine, dactinomycin, etoposide, vincristine) and FA (5-fluorouracil (5-FU), dactinomycin), may be as effective as EMA/EP and associated with fewer side effects; however, this is not clear from the available evidence and needs testing in well-designed RCTs. In the UK, an RCT comparing interventions for resistant/recurrent GTN will be very challenging owing to the small numbers of patients with this scenario. International multicentre collaboration is therefore needed to provide the high-quality evidence required to determine which salvage regimen/s have the best effectiveness-to-toxicity ratio in low- and high-risk disease. Future research should include economic evaluations and long-term surveillance for secondary neoplasms.

The impact of surgery for vulval cancer upon health-related quality of life and pelvic floor outcomes during the first year of treatment: a longitudinal, mixed methods study

OBJECTIVE

To measure the long-term impact of surgical treatment for vulval cancer upon health-related quality of life and pelvic floor outcomes during the first year of therapy.

METHODS

Prospective, longitudinal, mixed-methods study. Twenty-three women aged >18 years with a new diagnosis of vulval cancer were recruited. The EORTC QLQ C30, SF-36 and an electronic pelvic floor assessment questionnaire (ePAQ-PF) were administered at baseline (pre-treatment) and 3, 6, 9 and 12 months post-treatment. Mixed effects repeated measures models (all adjusted for age and BMI) were used to investigate changes over time and differences between cancer stage. Qualitative interviews were carried out with 11 of the women and analysed using a thematic approach.

RESULTS

Mean age was 59.9 years (SD = 15.3; range = 23.8-86.6 yrs). Mean BMI was 30.0 (SD = 4.5; range = 24.4-38.2). Sixteen women had early (Stage 1 to 2B), and seven women had advanced stage disease (Stage 3 to 4B). Questionnaire scores revealed that physical and social functioning, fatigue, pain and general sex life were significantly worse at 12 months than pre-treatment (p = < 0.05). Qualitative analysis revealed multiple treatment side effects which were perceived as severe and enduring. Women with advanced vulval cancer had significantly worse SF-36 mental health scores at 12 months compared to women with early stage disease (p = 0.037).

CONCLUSIONS

Surgery for vulval cancer has long-term implications which can be persistent 12 months post-treatment. High rates of morbidity relating to lymphoedema and sexual function re-enforce the need for specialist clinics to support women who suffer these complications. © 2015 The Authors.

Understanding the impact of the treatment pathway upon the health-related quality of life of women with newly diagnosed endometrial cancer - a qualitative study

PURPOSE

(1) To determine the impact of treatment and recovery on the health-related quality of life (HRQoL) of endometrial cancer (EC) patients. (2) To explore how treatment types and delivery affect HRQoL and invite suggestions for improvement.

METHODS

Qualitative study. In-depth, semi-structured interviews at 3, 6, 9 or 12 months post-treatment were carried out with 22 women with stage IA to IVB EC who had undergone treatment at a tertiary referral centre for gynaecological cancers in Sheffield, UK. 21 were treated surgically and 4 received adjuvant treatment. Data were analysed using an inductive thematic approach.

RESULTS

Four dominant themes emerged regarding the treatment pathway: pre-treatment concerns, experience during treatment, post-treatment and survivorship issues. Expectations and understandings of EC and its treatment were often inaccurate. Proper explanations eased anxiety but were uncommon. Laparoscopic surgery was welcomed where offered but did not necessarily influence coping ability. Instead, women evaluated treatment impacts against their expectations. Treatments affected women's physical abilities, self-perception and relationships resulting in re-evaluation of lifestyle.

CONCLUSIONS

The impact of treatment upon HRQoL for women with EC differs from other gynaecological cancers. Better information provision would enhance coping ability. Coping methods and expectations appear to influence HRQoL more than treatment modality.

First-line chemotherapy in low-risk gestational trophoblastic neoplasia

BACKGROUND

This is an update of a Cochrane review that was first published in Issue 1, 2009. Gestational trophoblastic neoplasia (GTN) is a rare but curable disease arising in the fetal chorion during pregnancy. Most women with low-risk GTN will be cured by evacuation of the uterus with or without single-agent chemotherapy. However, chemotherapy regimens vary between treatment centres worldwide and the comparable benefits and risks of these different regimens are unclear.

OBJECTIVES

To determine the efficacy and safety of first-line chemotherapy in the treatment of low-risk GTN.

SEARCH METHODS

In September 2008, we electronically searched the Cochrane Gynaecological Cancer Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL Issue 3, 2008), MEDLINE and EMBASE. In addition, we searched online trial registers, conference proceedings and reference lists of identified studies. We re-ran these searches in February 2012 for this updated review.

SELECTION CRITERIA

For the original review, we included randomised controlled trials (RCTs), quasi-RCTs and non-RCTs that compared first-line chemotherapy for the treatment of low-risk GTN. For this updated version of the review, we included only RCTs.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies for inclusion and extracted data to a pre-designed data extraction form. Meta-analysis was performed by pooling the risk ratio (RR) of individual trials.

MAIN RESULTS

We included five moderate to high quality RCTs (517 women) in the updated review. These studies all compared methotrexate with dactinomycin. Three studies compared weekly intramuscular (IM) methotrexate with bi-weekly pulsed intravenous (IV) dactinomycin (393 women), one study compared five-day IM methotrexate with bi-weekly pulsed IV dactinomycin (75 women) and one study compared eight-day IM methotrexate-folinic acid (MTX-FA) with five-day IV dactinomycin (49 women).Overall, dactinomycin was associated with significantly higher rates of primary cure than methotrexate (five studies, 513 women; RR 0.64, 95% Confidence Interval (CI) 0.54 to 0.76). Methotrexate was associated with significantly more treatment failure than dactinomycin (five studies, 513 women; RR 3.81, 95% CI 1.64 to 8.86). We consider this evidence to be of a moderate quality.There was no significant difference between the two groups with respect to nausea (four studies, 466 women; RR 0.61, 95% CI 0.29 to 1.26) or any of the other individual side-effects reported, although data for all of these outcomes were insufficient and too heterogeneous to be conclusive. No severe adverse effects (SAEs) occurred in either group in three out of the five included studies and there was no significant difference in SAEs between the groups overall (five studies, 515 women; RR 0.35, 95% CI 0.08 to 1.66; I² = 60%), however, there was a trend towards fewer SAEs in the methotrexate group. We considered this evidence to be of a low quality due to substantial heterogeneity and low consistency in the occurrence/reporting of SAEs between trials.

AUTHORS' CONCLUSIONS

Dactinomycin is more likely to achieve a primary cure in women with low-risk GTN, and less likely to result in treatment failure, compared with methotrexate. There is limited evidence relating to side-effects, however, the pulsed dactinomycin regimen does not appear to be associated with significantly more side-effects than the low-dose methotrexate regimen and therefore should compare favourably to the five- and eight-day methotrexate regimens in this regard.We consider pulsed dactinomycin to have a better cure rate than, and a side-effect profile at least equivalent to, methotrexate when used for first-line treatment of low-risk GTN. Data from a large ongoing trial of pulsed dactinomycin compared with five- and eight-day methotrexate regimens is likely to have an important impact on our confidence in these findings.

Predicting gestational trophoblastic neoplasia (GTN): is urine hCG the answer?

BACKGROUND

Previous studies on the significance of hCG to predict gestational trophoblastic neoplasia (GTN) have been too small for robust conclusions to be reached. Our aim in this study was to analyse the significance of urine hCG in predicting GTN in a large population.

METHODS

Details of 3926 patients were available for analysis. Information regarding age, dates of diagnosis and registration, urine hCG levels, antecedent pregnancy and chemotherapy were prospectively collected and used for analyses. Patients were stratified into different groups according to urine hCG level (IU/L); < 50, 50-99, 100-249, 250-499, 500-999, 1000-9999 and ≥10,000. Multivariate analyses were used to identify the prognostic indicators of GTN.

RESULTS

Urine hCG and antecedent pregnancy were the most powerful indicators for developing GTN (P<0.01). None of the patients with partial mole and urine hCG <50 IU/L (Normal level=40 IU/L) developed GTN. The risk of GTN was >35% in all patients with urine hCG ≥500 IU/L. GTN developed in 70% of patients with complete mole and urine hCG ≥10,000 IU/L.

CONCLUSION

Urine hCG is sensitive test for GTN. Urine hCG level is a powerful prognostic indicator for the GTN. Patients with partial mole could be safely discharged from the surveillance programme once their hCG have normalised. Patients with urine hCG ≥249 IU/L, whether partial or complete molar pregnancy, appear to benefit from intensive surveillance. Prophylactic chemotherapy could be considered when there are problems with surveillance.

First line chemotherapy in low risk gestational trophoblastic neoplasia

BACKGROUND

Gestational trophoblastic neoplasia (GTN) is a rare but curable disease. The incidence in Europe and North America is nearly 1.5 per 1000 live births but much higher rates are reported from Africa and Asia. The majority of the patients respond to evacuation of the uterus plus or minus chemotherapy, however, occasional patients will die. Patients are categorised into low or high risk groups using a variety of scoring systems. A large number of regimens are used worldwide in the management of low risk GTN; there are reports of 14 different regimens in the English literature. The choice of the regimen is usually dependent on geographic location, prior training and current experience with the specific regimen. Regimens have significant differences in the route of administration, hospitalisation and side effects and so have a bearing on healthcare cost. Patients are therefore exposed to different regimens with the potential for different response rates and different side effect profiles.

OBJECTIVES

To determine the efficacy and safety of first line chemotherapy in the treatment of low risk GTN.

SEARCH STRATEGY

We electronically searched Cochrane Gynaecological Cancer Group Specialized Register, Cochrane Central Register of Controlled Trials (CENTRAL, Issue 3 2008), MEDLINE and EMBASE in September 2008. We performed additional searching of online trial registers and conference proceedings. We cross examined article references to identify relevant papers not detected by the electronic search.

SELECTION CRITERIA

The review included randomised controlled trials (RCTs) , quasi-RCTs and non-RCTs (cohort and case control studies (CCS)) for the treatment of low risk GTN.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies for inclusion in the review using a data extraction form. Meta-analysis was performed by pooling the relative risk (RR) of individual trials.

MAIN RESULTS

Eight studies met the review entry criteria (n = 769). There were four RCTs and four CCS. Six different treatment regimens were identified; weekly methotrexate, 5-day methotrexate, 8-day methotrexate-folinic acid, "pulsed" dactinomycin, 5-day dactinomycin and the combination of methotrexate and dactinomycin. "Pulsed" dactinomycin was superior to weekly methotrexate in achieving primary cure without significantly increasing toxicity (three studies, RR 3.00, 95% CI 1.10 to 8.17, n = 392) . Eight-day methotrexate-folinic acid did not show significant advantage over 5-day methotrexate both in reducing toxicity or primary cure rate (two studies, RR 1.07, 95% CI 0.91 to 1.25, n = 169). The combination of methotrexate-dactinomycin resulted in significantly increased toxicity without significantly improving primary cure rate.

AUTHORS' CONCLUSIONS

Based on the available evidence from the included RCTs, the authors conclude that "pulsed" dactinomycin is superior to weekly parenteral methotrexate at the reported dosages. However, the authors believe that rigorously designed, multicentred, randomised double-blind trials are required to evaluate other combinations of chemotherapy regimens, most importantly "pulsed" dactinomycin with the widely used 8-day methotrexate-folinic acid.

Role of hysterectomy in managing persistent gestational trophoblastic disease

OBJECTIVE

To evaluate incidence, indications and outcomes of hysterectomy for gestational trophoblastic disease (GTD) and compare outcomes for patients who underwent primary hysterectomy with outcomes for those who underwent adjuvant hysterectomy.

STUDY DESIGN

Using the Sheffield Trophoblastic Tumour Centre database (January 1, 1986, until June 30, 2007), patients who underwent hysterectomy were identified, along with age, antecedent pregnancy, diagnosis date, hysterectomy date and chemotherapy and pathologic findings.

RESULTS

A total of 8,860 patients were registered at Weston Park Hospital, Sheffield. Of them, 627 (7.1%) needed chemotherapy and 62 (0.71%) underwent hysterectomy. The most frequent indication was resistance to chemotherapy in 22 of 62 (35.5%), followed by major hemorrhage in 21 of 62 (33.9%). Emergent hysterectomy was performed in 22 (35.5%). Mean International Federation of Gynecology and Obstetrics risk score was 6.5. Choriocarcinoma was the most frequent pathology (23), followed by invasive mole (10) and placental site trophoblastic tumor (9). Thirty-one patients needed chemotherapy after hysterectomy, 93.5% are in remission, 7 relapsed, 3 were cured and 4 died of disease.

CONCLUSION

Incidence of hysterectomy for GTD was 1 in 140. Patients who underwent hysterectomy represent a high-risk group, often having more aggressive pathology. Hysterectomy is valuable as primary and adjuvant treatments.
