Role of Adjuvant Hysterectomy in Management of High-Risk Gestational Trophoblastic Neoplasia

Invasive Mole Mimicking Abnormal Uterine Bleeding: A Case Report

Invasive mole (IM) is a very uncommon subtype of gestational trophoblastic disease (GTD), which is the invasion of molar tissue into the uterine or myometrial vasculature. However, this report presents a rare case of a 41-year-old female multiparous P7 with five full-term normal vaginal deliveries and two preterm normal vaginal deliveries. As the patient was not using contraception, her urine pregnancy test (UPT) was done, which demonstrated positive results. A speculum examination revealed a healthy cervix with just mild bleeding, whereas a vaginal examination revealed a firm cervix and an anteverted and mobile eight-week-old uterus along with a free fornix. Pelvic ultrasound and magnetic resonance imaging (MRI) demonstrated the diagnosis of GTD, for which consultation from an oncology physician was taken and the treatment proceeded with a total abdominal hysterectomy. Histological examination of the uterus showed a circumscribed nodule showing a large area of hemorrhage with few chorionic villi lined with trophoblastic cells and occasional villi invading the myometrium and endometrial cavity suggesting hydatidiform mole showing early invasion that confirmed the diagnosis of IM. In conclusion, reproductive-age women who experience abnormal uterine bleeding (AUB) should suspect pregnancy with several possible complications, for which a pregnancy test should be done to rule out complications.

Invasive mole in a perimenopausal woman with lung and vaginal metastases: A case report

Gestational trophoblastic disease can result in serious complications and disease progression. Therefore, follow-up of such patients is essential for early detection of malignant trophoblastic tumors and to reduce mortality rate. Primary treatment is chemotherapy but hysterectomy should be considered in patients who have uncontrollable hemorrhage and hemodynamic instability.

Total hysterectomy versus uterine evacuation for preventing post-molar gestational trophoblastic neoplasia in patients who are at least 40 years old: a systematic review and meta-analysis

Background

The clinical value of total hysterectomy for patients with hydatidiform mole (HM) being at least 40 years old remains highly controversial. Since the practice of hysterectomy has been applied globally for decades, there is an urgent need to perform a systematic review to assess its risks and benefits.

Methods

Six electronic databases, including four English databases and one Chinese database, were searched from the inception of each database till October 6th 2017. Studies were included if they: 1) were human studies, 2) explicitly indicated exposure to hysterectomy, 3) explicitly indicated control to uterine evacuation, 4) explicitly indicated the participants were older patients with HM being at least 40 years in age, 5) compared the outcome of interest as the incidence of post-molar GTN. Two authors independently conducted the literature search, study selection, data extraction. Pooled odds ratios were analyzed using Review Manager 5.3.

Results

The overall pooled effect size of total hysterectomy had a significant advantage in preventing post-molar gestational trophoblastic neoplasia over uterine evacuation with an OR of 0.19 (95% CI, 0.08–0.48; P = 0.0004) and a low heterogeneity (I² = 21%, P = 0.28). Subgroup analysis and sensitivity analysis also showed similar results.

Conclusions

Total hysterectomy, as compared to uterine evacuation, is a better therapeutic method for patients with HM being at least 40 years old unless fertility is still desired.

Fertility-sparing uterine lesion resection for young women with gestational trophoblastic neoplasias: single institution experience

Purpose

To evaluate the oncological safety and pregnant outcomes of fertility-sparing uterine lesion resection in treating gestational trophoblastic neoplasias.

Results

After the treatment of surgery and chemotherapy, all the patients achieved complete remission. With a median follow-up time of 44 months (range, 6-188), 3 patients (3.85%) relapsed within 3-26 months. Multivariate analysis showed that tumor size was the independent risk factor of recurrence and the cutoff value was 4.2cm. Among 37 patients who attempted to conceive, 31 achieved clinical pregnancy. The rate of pregnancy and live birth were 83.8% and 77.4%. Uterine rupture did not occurred no matter in cesarean section or vaginal delivery. No congenital abnormalities were reported among the live births.

Methods

From January 1995 to December 2014, 78 patients with gestational trophoblastic neoplasias who underwent fertility-sparing uterine lesion resection at Peking Union Medical College Hospital were reviewed. The complete remission rate, fertility rate, pregnant outcomes and risk factors of recurrence were analyzed.

Conclusions

Fertility-sparing uterine lesion resection might be considered as a safe and reasonable alternative for high-selected young women to remove uterine lesion in the treatment of gestational trophoblastic neoplasias.

The added value of hysterectomy in the management of gestational trophoblastic neoplasia

BACKGROUND

Despite the undoubted effectiveness of chemotherapeutic treatment in gestational trophoblastic neoplasia (GTN), problems related to toxicity of chemotherapy and chemo-resistant disease have led to reconsideration of the use of hysterectomy. Aim of the present study was to evaluate indications for and outcome of hysterectomy in patients with GTN in a nation-wide cohort.

METHODS

Between 1977 and 2012, we identified all patients diagnosed with GTN and treated with hysterectomy from the Dutch national databases. Demographics, clinical characteristics and follow-up were recorded retrospectively.

RESULTS

One hundred and nine patients (16.5% of all registered patients with GTN) underwent hysterectomy as part of their management for GTN. The majority of patients was classified as low-risk disease (74.3%), post-molar GTN (73.5%) and disease confined to the uterus (65.1%). After hysterectomy, complete remission was achieved in 66.2% of patients with localized disease and in 15.8% of patients with metastatic disease. For patients with localized disease, treated with primary hysterectomy, treatment duration was significantly shorter (mean 3.2weeks and 8.0weeks respectively, p=0.01) with lower number of administered chemotherapy cycles (mean 1.5 and 5.8 respectively, p<0.01) than patients in a matched control group.

CONCLUSION

In selected cases, a hysterectomy may be an effective means to either reduce or eliminate tumor bulk. Primary hysterectomy should mainly be considered in older patients with localized disease and no desire to preserve fertility, whereas patients with chemotherapy-resistant disease may benefit from additional hysterectomy, especially when disease is localized. For patients with widespread metastatic disease, the benefit of hysterectomy lies in the removal of chemotherapy-resistant tumor bulk with subsequent effect on survival.

Analysis of the prognosis and related factors for patients with stage IV gestational trophoblastic neoplasia

OBJECTIVE

This study aimed to investigate and analyze the treatments and prognoses of patients with stage IV gestational trophoblastic neoplasia (GTN).

METHODS

Between January 1990 and January 2010, 105 patients with stage IV GTN were treated in our hospital (Peking Union Medical College Hospital). A retrospective study is presented herein to report the prognoses of these patients and to statistically analyze the risk factors that affected the prognoses of patients with stage IV GTN.

RESULTS

After the treatments, of the 105 patients, 71 (67.6%) patients achieved complete remission, 15 (14.3%) patients exhibited partial remission, and 19 (18.1%) patients exhibited progression of the disease. In total, of the 105 patients, 30 (28.6%) patients died. Our statistical analyses have revealed that a previously failed multidrug chemotherapy history, multiorgan metastasis concomitant with renal metastasis, and surgical intervention all affected the prognoses of patients with stage IV GTN. In addition, patients with stage IV GTN with International Federation of Gynecology and Obstetrics scores below 12 were relatively more likely to obtain complete remission.

CONCLUSIONS

Multidrug, multiroute chemotherapy, assisted by surgery when necessary, is the predominant strategy for patients with stage IV GTN. Fluorouracil-based multidrug chemotherapy can produce good outcomes for patients with stage IV GTN who were treated primarily. Adequate attention should be given to patients who have previously failed multidrug chemotherapy, have experienced multiorgan metastasis concomitant with renal metastasis, or have International Federation of Gynecology and Obstetrics scores of more than 12.
