RESUMO
BACKGROUND: Intravenous leiomyomatosis (IVL), pulmonary benign metastatic leiomyomatosis (PBML), and leiomyomatosis peritonealis disseminata (LPD) are leiomyomas with special growth patterns and high postoperative recurrence rates. We report the safety and efficacy of a pilot study of sirolimus in the treatment of recurrent IVL, PBML, and recurrent LPD. METHODS: This was a pilot study to evaluate the safety and efficacy of sirolimus in the treatment of leiomyomatosis (ClinicalTrials.gov identifier NCT03500367) conducted in China. Patients received oral sirolimus 2 mg once a day for a maximum of 60 months or until disease progression, intolerable toxicity, withdrawal of consent, or investigator decision to stop. The primary end point of this study was the objective response rate. Secondary end points included safety and tolerability, disease control rate, and progression-free survival. RESULTS: A total of 15 patients with leiomyomatosis were included in the study, including five with recurrent IVL, eight with PBML and two with recurrent LPD. The median follow-up time was 15 months (range 6-54 months), nine patients (60%) had treatment-related adverse events (including all levels), and two patients had treatment-related grade 3 or 4 adverse events. The objective response rate was 20.0% (95% CI, 7.1-45.2%), and the disease control rate was 86.7% (95% CI, 62.1-96.3%). Partial response was achieved in three patients. The median response time in the three partial response patients was 33 months (range 29-36 months), and the sustained remission time of these three patients reached 0, 18, and 25 months, respectively. CONCLUSIONS: Sirolimus was safe and effective in the treatment of recurrent IVL, PBML, and recurrent LPD. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT03500367. Registered on 18 April 2018.

OBJECTIVE: To elucidate the clinicopathological characteristics and oncological outcomes of a special group of patients with gestational trophoblastic neoplasia (GTN) initially presenting with isolated lung lesions, elevated human chorionic gonadotropin (hCG) levels, and unobserved pelvic lesions. METHODS: Overall, 2358 patients with GTN treated at our hospital between 2000 and 2023 were retrospectively reviewed, and 40 patients were evaluated. The demographic characteristics, clinicopathological features, treatment data, and follow-up information of each patient were collected. The primary outcome was progression free survival. Kaplan-Meier analysis and univariate and multivariate Cox proportional hazard analyses were used to identify the risk factors. RESULTS: Among the 40 patients, 95.0 % had solitary lung lesions, with a median size of 1.9 cm. Moreover, 72.5 % of patients were pathologically confirmed as epithelioid trophoblastic tumors (ETT). During a median follow-up period of 53.5 months (range, 2-143), 11 patients experienced recurrence, including all patients who received chemotherapy alone as the initial treatment, and no death was observed. Relapse treatment involved lung segmentectomy and lobectomy combined with chemotherapy and immunotherapy. Univariate and multivariate Cox analyses identified comparing with surgery±chemotherapy, chemotherapy alone as the initial treatment (hazard ratio [HR] =7.738, 95 % confidence interval [CI] 1.698-35.269, P = 0.008) as independent risk factor for recurrence. CONCLUSIONS: In patients with a history of pregnancy exhibiting isolated pulmonary lesions, elevated hCG levels (mostly <1000 mIU/mL), and unobserved pelvic lesions, ETT should be considered first. Surgical resection of lung lesion is crucial for optimal management. When chemotherapy is considered, multidrug regimen is recommended.
RESUMO
OBJECTIVE: Treatment options for heavily pre-treated recurrent ovarian and endometrial cancer are limited. Lenvatinib plus anti-programmed cell death protein-1 (PD-1) combination therapy has been efficacious in advanced endometrial cancer, but at the recommended dose level, high-grade adverse events occur and lead to drug discontinuation. This study evaluated the feasibility of low-dose lenvatinib plus anti-PD-1 therapy in patients with recurrent ovarian and endometrial cancer. METHODS: This is a single-arm, protocol-based pilot study. Patients with recurrent ovarian cancer or endometrial cancer who had at least one line of previous therapy were included and given lenvatinib 8 or 12 mg daily (based on the patient's weight) and anti-PD-1 therapy. The primary endpoint was the objective response rate. RESULTS: Twenty-one patients were enrolled, including 15 with ovarian cancer and six with endometrial cancer. All patients were pre-treated, and the median number of lines of previous treatment of the ovarian and endometrial cancer cohorts was three and two, respectively. After a median follow-up of 11.0 months (range 6.8-23.9), the objective response rate for the ovarian cancer and endometrial cancer cohorts was 46.7% (95% CI 21.3% to 73.4%) and 66.7% (95% CI 22.3% to 95.7%), respectively. The median duration of response for the ovarian cancer and endometrial cancer cohorts was 5.3 (95% CI 0 to 11.7) and 6.1 (95% CI 2.4 to 9.8) months, respectively. The median progression-free survival for the ovarian cancer and endometrial cancer cohorts was 4.1 (95% CI 2.6 to 5.6) and 6.6 (95% CI 1.7 to 11.5) months, respectively. No grade 4 or 5 adverse events occurred. Eight (38.1%) patients had a lenvatinib dose reduction. There was no discontinuation of lenvatinib alone, and only one patient discontinued both drugs due to adverse events. CONCLUSION: Low-dose lenvatinib in combination with anti-PD-1 therapy showed promising efficacy and favorable tolerability in patients with heavily pre-treated ovarian and endometrial cancer.

OBJECTIVE: Non-platinum chemotherapy is used in platinum resistant/refractory ovarian cancer patients but offers limited efficacy, especially in those who develop platinum resistance after ≤2 lines of platinum based chemotherapy. This phase II study aimed to evaluate the efficacy and safety of oral niraparib plus etoposide in platinum resistant/refractory ovarian cancer. METHODS: Platinum resistant/refractory ovarian cancer patients after ≤2 lines of platinum based chemotherapy, histologically confirmed as non-mucinous epithelial ovarian cancer, regardless of biomarker status, were eligible. Patients received niraparib with a starting dose of 200 mg/100 mg alternate once a day, and oral etoposide of 50 mg once a day, on days 1-20 of 30 days per cycle for a maximum of 6-8 cycles, followed by niraparib until disease progression or intolerable toxicity. The primary endpoint was investigator assessed progression free survival. RESULTS: 29 patients were enrolled from 22 May 2020 to 3 February 2023; 26 patients were included in the efficacy analysis set as per protocol. Median progression free survival was 4.2 months (95% confidence interval (CI) 3.9 to 4.4). Overall response rate was 26.9% (95% CI 8.7 to 45.2). Disease control rate was 57.7% (95% CI 37.3 to 78.0). Overall response rate in patients with a BRCA mutation and homologous recombination deficiency was 50% and 41.7%, respectively. Median progression free survival in patients with primary platinum resistance was 4.5 months (95% CI 3.6 to 5.3). 29 patients were included in the safety analysis set, and 8 (28%) patients experienced treatment related adverse events of grade ≥3. There was no treatment related discontinuation. CONCLUSIONS: Niraparib combined with etoposide showed evidence of antitumor activity in platinum resistant/refractory ovarian cancer after ≤2 lines of platinum based chemotherapy, particularly in patients with a BRCA mutation, homologous recombination deficiency, or primary platinum resistance. This once-a-day oral combination was a convenient option. TRIAL REGISTRATION NUMBER: NCT04217798.
RESUMO
BACKGROUND: Single-agent chemotherapy using methotrexate or actinomycin D is the first-line treatment for patients with low-risk gestational trophoblastic neoplasia. Various methotrexate-based and actinomycin D-based single-agent regimens can be used. However, there is insufficient evidence to determine the superior regimen. To guide doctors in selecting a single-agent chemotherapy regimen for patients with low-risk gestational trophoblastic neoplasia, we will compare two regimens. METHODS: We will conduct a multicentre, randomized, prospective clinical trial. Selected low-risk gestational trophoblastic neoplasia patients (FIGO score 0-4) will be randomized 1:1 to a biweekly single-dose actinomycin D group or a multiday methotrexate therapy group. The actinomycin D group will receive IV pulse actinomycin D (1.25 mg/m2) every 14 days, and the methotrexate group will receive methotrexate (50 mg) intramuscularly on days 1, 3, 5, and 7 (4 doses per cycle) and leucovorin (15 mg) intramuscularly on days 2, 4, 6, and 8. This process will be repeated every 14 days. The primary endpoints will include the complete remission rate by single-agent therapy and the overall complete remission rate. The secondary endpoints will include the duration needed to achieve complete remission after single-agent chemotherapy, number of courses needed to achieve complete remission after single-agent chemotherapy, incidence and severity of adverse effects, effects on menstrual conditions and ovarian function based on the anti-Mullerian hormone level, and patient-reported quality of life. DISCUSSION: Previous clinical trials comparing biweekly single-dose actinomycin D with multiday methotrexate therapy for treating low-risk gestational trophoblastic neoplasia patients failed to meet the expected case number. Through this multicentre study, the complete remission ratio and efficacy difference between biweekly single-dose actinomycin D and multiday methotrexate therapy will be obtained. This study will also provide the basis for formulating a preferred regimen for treating patients with low-risk gestational trophoblastic neoplasia.

OBJECTIVE: To analyze the methods, feasibility, efficiency, and fertility outcomes of fertility-sparing treatment for patients with placental site trophoblastic tumor (PSTT). METHODS: Clinical data of patients diagnosed with PSTT between April 1998 and April 2020 from Peking Union Medical College Hospital (PUMCH) were retrospectively collected. The clinical features, treatment, and outcomes of patients received fertility-sparing treatment were analyzed and compared with patients suffered hysterectomy. RESULTS: In total, 126 patients were included in the study and 29 of them received fertility-sparing treatment. Besides significantly younger age and lower proportion of antecedent term delivery were seen in fertility-sparing group than hysterectomy group, no significant differences were observed in stage, serum ß-hCG level, or interval from antecedent pregnancy between the two groups. Conservative surgery was selected individualized and none of them suffered salvage hysterectomy. Patients with clinical or pathological high-risk factors received adjuvant chemotherapy, yet the fertility-sparing treatment did not significantly lengthen chemotherapy duration. All patients in fertility-sparing group achieved complete remission without relapse after 36 to 176 months of follow-up and had sixteen healthy term delivery more than one year after the treatment. CONCLUSIONS: Fertility-sparing treatment for PSTT can be considered for young patients with localized uterine lesions who strongly desire to preserve their fertility potential. With individualized conservative surgery and selected adjuvant chemotherapy, fertility-sparing treatment will not influence the risk of relapse or overall survival and patients will achieve favorable pregnancy and live birth outcomes.

OBJECTIVE: This study aimed to explore the single-agent chemotherapy actinomycin D on ovarian reserve by measuring the anti-Mullerian hormone (AMH) levels before, during, and after chemotherapy. METHODS: This study recruited premenopausal women aged 15 to 45 with a newly diagnosed low-risk gestational trophoblastic neoplasia needing actinomycin D. AMH was measured at baseline, during chemotherapy, and 1, 3, and 6 months after the last chemotherapy. The reproductive outcomes were also documented. RESULTS: Of the 42 women recruited, we analyzed 37 (median: 29 years; range 19-45) with a complete dataset. The follow-up was 36 months (range 34-39). Actinomycin D significantly decreased AMH concentrations during treatment, from 2.38±0.92 ng/mL to 1.02±0.96 ng/mL (p<0.05). Partial recovery was seen at 1 month and 3 months after treatment. Full recovery was reached 6 months after treatment among patients younger than 35 years. The only factor correlated with the extent of AMH reduction at 3 months was age (r=0.447, p<0.05). Notably, the number of courses of actinomycin D was not associated with the extent of AMH reduction. A total of 18 (90%) of 20 patients who had a desire to conceive had live births with no adverse pregnancy outcomes. CONCLUSION: Actinomycin D has a transient and minor effect on ovarian function. Age is the only factor that impacts the patient's rate of recovery. Patients will achieve favorable reproductive outcomes after actinomycin D treatment.

OBJECTIVE: To evaluate the prognosis and recurrence in patients with residual lesions of pulmonary metastasis from gestational trophoblastic neoplasia after initial treatment, and to explore the clinical significance of pulmonary resection. METHODS: A retrospective analysis was performed on 606 patients with residual lesions from pulmonary metastasis after receiving standardized chemotherapy as initial treatment in Peking Union Medical College Hospital from January 2002 to December 2018. Patients were divided into surgery (51 patients) and non-surgery (555 patients) groups. The prognosis of these patients was compared. Risk factors affecting recurrence were analyzed to explore the effect of pulmonary resection. RESULTS: Among low risk patients, complete remission rate was 100% and recurrence rate was <1% in both groups. Among high risk patients, complete remission and recurrence rates were 93.5% and 10.3% in the surgery group and 94.7% and 14.3% in the non-surgery group, respectively. There was no significant difference in prognostic features between the two groups (all p>0.05). No significant difference was found in recurrence rates based on recurrence risk factors (≥3.2 cm residual lung lesions, prognosis score ≥9.0, and drug resistance) between the two groups (all p>0.05). CONCLUSION: After standardized chemotherapy, pulmonary resection was not necessary for initially treated stage III gestational trophoblastic neoplasia patients whose blood ß human chorionic gonadotropin levels normalized and residual lung lesions remained stable. These patients should be closely monitored during follow-up, regardless of the size of the residual lung lesions or high/low risk score, especially within a year after complete remission.

BACKGROUND: Pulmonary benign metastasizing leiomyoma (PBML) is the most common extrauterine spread of uterine leiomyoma, and its biological behavior is traditionally thought to be hormone dependent. Studies on older PBML patients have been previously reported, but limited literature has been published regarding the clinical features and treatment of PBML in young women. METHODS: A total of 65 cases of PBML in women aged 45 years and younger were reviewed, including 56 cases selected from PubMed and 9 cases from our hospital. The clinical characteristics and management of these patients were analyzed. RESULTS: The median age of all the patients at diagnosis was 39.0 years. PBML most commonly presented as bilateral solid lesions (60.9%), with other rare imaging manifestations. The median interval time from a pertinent gynecologic procedure to diagnosis was 6.0 years. A total of 16.7% of patients received careful observation, and all achieved stable status in a median follow-up time of 18.0 months. A total of 71.4% of patients were administered anti-estrogen therapies, including surgical castration (33.3%), gonadotropin-releasing hormone analog (23.8%) and anti-estrogen drugs (14.3%). Eight of 42 patients underwent surgical resection of metastatic lesions. Patients who underwent curative surgery for the removal of pulmonary lesions combined with adjuvant anti-estrogen therapies had favorable outcomes compared with those who only underwent surgical resection. The disease control rates of surgical castration, gonadotropin-releasing hormone analog, and anti-estrogen drugs were 85.7%, 90.0%, and 50.0%, respectively. For two patients, sirolimus (rapamycin) achieved successful relief of symptoms and control of pulmonary lesions without lowering hormone levels and causing estrogen deficiency symptoms. CONCLUSIONS: In the absence of standard treatment guidelines for PBML, maintaining a low-estrogen environment using different kinds of antiestrogen therapies has been the mainstream strategy and has satisfying curative effects. A wait-and-see strategy might be an option, but therapeutic approaches must be contemplated when complications or symptoms progress. For PBML in young women, the negative effect on ovarian function of anti-estrogen treatment, especially surgical castration, should be considered. Sirolimus might be a new treatment option for young PBML patients, especially for those who want to preserve ovarian function.

BACKGROUND: Guidelines recommend etoposide, methotrexate, actinomycin D (EMA)/cyclophosphamide, vincristine (CO) as first-line treatment for high-risk gestational trophoblastic neoplasia (GTN). However, the floxuridine, actinomycin D, etoposide and vincristine (FAEV) regimen is commonly used to treat these patients in China. We conducted a randomised controlled trial to compare the efficacies and toxicities of FAEV and EMA/CO. METHODS: Ninety-four patients with GTN were enrolled between May 2015 and April 2019 and randomly assigned to the FAEV or EMA/CO regimen. The rates of complete remission and relapse and the toxicities were compared in August 2021. RESULTS: Five patients were excluded from the analysis. There were 46 patients in the FAEV group and 43 patients in the EMA/CO group. The complete remission rates following primary treatment were 89.1% and 79.1% (P = 0.193), respectively. The relapse rates were 8.7% and 9.3% (P = 0.604). The apparent incidences of grade 4 myelosuppression were 60.9% and 32.6% (P = 0.008), respectively; however, they became both 32.6% (P = 0.996) after granulocyte colony-stimulating factor support. Other adverse reactions were similar in the two groups. No patient died of disease. CONCLUSION: FAEV has comparable efficacy and toxicity to EMA/CO as the primary treatment for high-risk GTN, and may thus be another first-line choice of chemotherapy.

BACKGROUND: 5-fluorouracil-based multiagent chemotherapy has been used as the primary treatment for high-risk gestational trophoblastic neoplasia (GTN) in China for a few decades. This study aims to assess the efficacy and toxicity of floxuridine, actinomycin D, etoposide, and vincristine (FAEV) as a primary treatment for patients with GTN who had International Federation of Gynecology and Obstetrics (FIGO) scores ≥5. MATERIALS AND METHODS: A total of 207 patients with GTN who had FIGO scores ≥5 were treated with FAEV as first-line chemotherapy at Peking Union Medical College Hospital between January 2002 and December 2017. Complete remission (CR), resistance, survival, toxicity, and reproductive outcomes were analyzed. RESULTS: Of the 207 patients treated with FAEV, 9 (4.3%) required a change of chemotherapy owing to toxicity and 1 (0.5%) died of cerebral hernia 5 weeks after commencing treatment. The remaining 197 patients were assessable to determine the response to FAEV; among them, 168 (85.3%) achieved CR with FAEV and 29 (14.7%) developed resistance to FAEV. The 5-year overall survival rate of the entire cohort was 97.4%. Grade 3-4 neutropenia, thrombocytopenia, and anemia occurred in 28.4%, 6.8%, and 6.2% of cycles, respectively. No acute toxicity-related deaths occurred. Five patients developed acute myeloid leukemia 10-50 months after exposure to chemotherapy; another patient developed duodenal cancer 2 years after completing therapy. Sixty-one patients who preserved fertility wanted to become pregnant; 56 of them conceived. CONCLUSION: The FAEV regimen is an effective primary treatment for patients with GTN who have FIGO scores ≥5 and has predictable and manageable toxicity. IMPLICATIONS FOR PRACTICE: The most commonly used multiagent chemotherapy for high-risk gestational trophoblastic neoplasia (GTN) is etoposide, methotrexate and actinomycin D/cyclophosphamide and vincristine (EMA/CO) worldwide. However, 5-fluorouracil-based multiagent chemotherapy has been used as a primary treatment for high-risk GTN in China for a few decades. This study evaluated the efficacy and toxicity of floxuridine, actinomycin D, etoposide, and vincristine (FAEV) as a primary treatment for patients with GTN who have International Federation of Gynecology and Obstetrics (FIGO) scores ≥5. The study's data demonstrated that FAEV as a primary treatment achieved favorable outcomes for patients with FIGO scores ≥5. Toxicities that result from the FAEV regimen are predictable and manageable. The FAEV regimen may provide another option for the treatment of GTN.

OBJECTIVE: To analyze the reproductive outcomes of gestational trophoblastic neoplasia (GTN) patients who were cured only by floxuridine-based regimens. METHODS: This was a retrospective analysis of 464 patients who were treated with only floxuridine-based regimens at Peking Union Medical College Hospital between January 2002 and December 2013 and retained their reproductive ability. Their reproductive outcomes were analyzed. The factors affecting pregnancy intention were identified by logistic regression. RESULTS: Of the 464 patients (average age, 28.0 ± 5.7 years; median follow-up = 85 months), the livebirth rate was 72.2%, while the rates of spontaneous abortion, induced abortion and ectopic pregnancy were 9.2% (n = 41), 8.7% (n = 39) and 1.8% (n = 8), respectively. The GTN recurrence rate was 2.1%. The time from chemotherapy completion to first conception in the induced abortion group was significantly shorter than those in spontaneous abortion, full-term/premature, and ectopic pregnancy groups (P ≤ 0.001, <0.001, =0.015, respectively). The logistic analysis showed that the age at onset of GTN (OR = 0.899, 95% CI 0.851-0.951, P < 0.001), parity at onset of GTN (parity = 1, OR = 0.123, 95% CI 0.068-0.225, P < 0.001; parity = 2-3, OR = 0.058, 95% CI 0.014-0.232, P < 0.001) and interval from the index pregnancy to chemotherapy were independent factors affecting pregnancy intention. Among the 36 pregnancies occurring within 12 months postchemotherapy, only one choriocarcinoma occurred, and 20 culminated in induced abortions (55.6%). CONCLUSIONS: After floxuridine-based chemotherapy, the pregnancy rate of GTN patients after fertility-preserving treatment is comparable to that of the normal population. Pregnancy losses within one year after chemotherapy completion are mainly caused by induced abortion.

BACKGROUND: Pulmonary benign metastasizing leiomyoma (PBML) is a rare disease characterized by leiomyoma of benign histopathology existing in the lungs. Because of its rarity, limited literature with a single case or small number of cases has been regarding to the clinical course, pathology or management of PBML. METHODS: A retrospective study was performed of all PBML cases diagnosed and managed at Peking Union Medical College Hospital (PUMCH) from 2001 to 2019. The clinical characteristics, pathology, treatment and outcomes of each case were studied. RESULTS: There were 25 PBML patients identified in the 19-year period in PUMCH, and 23 patients' data was analyzed. The median age at diagnosis was 46 years. There were 7 patients (30.4%) diagnosed with postmenopausal status. Two patients (8.7%) had no uterine leiomyoma, and 3 patients (13.0%) had no gynecologic surgery history. Immunohistochemistry of most lesions demonstrated positive for desmin, SMA and Estrogen/Progesterone Receptors; and negative for S-100 were shown in 7 cases. After curative or diagnostic surgeries for the PBML, several treatments from observation to medical or surgical castration were performed. Nine premenopausal patients preserved their ovaries at first. At a median follow-up of 8 years, 3 patients finally had oophorectomy. CONCLUSIONS: PBML is a rare disease and should be treated by individualization according to the patients' age, symptoms and extent of lesion. Curative surgery for patients with limited lesions can achieve the complete response. For patients that are young and asymptomatic, close observation is recommended as the first choice. All patients should undergo long-term surveillance.

BACKGROUND: Little data exists predicting the resistance to actinomycin D (Act-D) single-agent for gestational trophoblastic neoplasia (GTN). The objective was to determine the overall success of pulse Act-D and the factors predictive of resistance to pulse Act-D in the treatment of low-risk, non-choriocarcinoma post-molar GTN. METHODS: From January 2013 to October 2016, according to the FIGO criteria for the diagnosis of post-molar disease and the FIGO risk-factor scoring system for GTN, a total of 135 patients with post-molar non-choriocarcinoma GTN who were chemotherapy-naive with a FIGO score < 7 were treated with single-agent pulse Act-D as a first-line regimen, in Peking Union Medical College Hospital. The pulse Act-D regimen is defined as 1.25 mg/m2 (max 2 mg) IV push every other week. All patients were followed until May 2017. Epidemiological and clinical data were compared between patients with remission and resistance to Act-D to determine predictive factors by univariate and multivariate analysis. RESULTS: Ninety-six of 135 patients (71.1%) achieved complete remission after first-line chemotherapy of pulse Act-D. In multivariate analysis, existing invasive uterine lesions observed by pre-chemotherapy transvaginal ultrasound (odds ratio [OR] 7.5, 95% confidence intervals [CI] 2.7-20.8), FIGO score ≥ 5 (OR 15.2, 95% CI 1.5-156.1) and pre-chemotherapy levels of ß-hCG ≥ 4000 IU/L (OR 3.1, 95% CI 1.2-8.3) were independent high-risk factors predicting resistance to pulse Act-D as single-agent chemotherapy. During follow-up, no relapse, treatment-associated serious adverse events, or death occurred. CONCLUSIONS: As first-line chemotherapy, pulse Act-D was effective and tolerable for patients with low-risk post-molar non-choriocarcinoma. Existing invasive uterine lesions observed by pre-chemotherapy transvaginal ultrasound, a FIGO score ≥ 5, and pre-chemotherapy levels of ß-hCG ≥ 4000 IU/L were independent factors for resistance to pulse Act-D.

BACKGROUND: To re-evaluate the efficacy of the prognostic factors currently employed in the treatment of malignant gestational trophoblastic neoplasia. METHODS: Clinical data from the Gestational Trophoblastic Disease (GTD) Center at Peking Union Medical Hospital (PUMCH) collected between January 2002 and December 2013 were retrospectively analyzed. Univariate and multivariate analyses of prognostic factors were performed using the Cox proportional hazards model. A new hazard ratio (HR)-based prognostic scoring scale was established and compared with the original scoring system. RESULTS: In total, 1420 cases were included in the study (median follow-up=40months, overall complete remission (CR) rate=95.8%, relapse rate=7.1%, mortality rate=5.5%, median disease-free survival (DFS)=36months). Low-risk (0-6 points) and high-risk (≥6 points) patients exhibited CR rates of 99.8% (915/917) and 88.5% (445/503) and mortality rates of 0.3% and 15.1% (P<0.001), respectively. Univariate and multivariate analyses showed that age, pretreatment serum levels of human chorionic gonadotropin beta-subunit (ß-hCG) and maximum tumor diameter were not independent prognostic risk factors. Antecedent pregnancy, the interval from the index pregnancy, the number of metastases and a history of failed chemotherapy treatments were independent prognostic risk factors. By modifying the scoring system based on the variables identified in a Cox analysis, we significantly increased the area under the receiver operating characteristics (ROC) curve. CONCLUSION: Though effective, the accuracy of the International Federation of Gynecology and Obstetrics (FIGO) 2000 Trophoblastic Neoplasia Staging System requires improvement. Irrelevant prognostic factors should be removed, and the weights of other factors should be adjusted appropriately.

OBJECTIVE: The gestational trophoblastic neoplasia (GTN) patients with the International Federation of Gynecology and Obstetrics (FIGO) score≥12 are defined as ultra high-risk GTN. This study aims to investigate the clinical characteristics, the treatment efficiency, and the prognosis of ultra high-risk GTN patients. METHODS: Between January 2002 and December 2015, medical record data of 143 GTN patients with FIGO score≥12 at Peking Union Medical College Hospital (PUMCH) were reviewed. Ratios were compared using chi-square test, and prognostic risk factors were analyzed by univariate analysis and multivariate analysis. RESULTS: Among the 143 ultra high-risk GTN patients, 94 (65.7%) patients had achieved complete remission and 15.9% (15/94) patients relapsed after complete remission. The 5-year overall survival (OS) rate of the entire cohort approached 67.9%. The results of the multivariate analysis revealed that non-molar antecedent pregnancy [Relative risk (RR) 4.689, 95% CI 1.448-15.189, P=0.010], brain metastases (RR 2.280, 95% CI 1.248-4.163, P=0.007), previous failed multiagent chemotherapy (RR 5.345, 95% CI 2.222-12.857, P=0.000) and surgery (RR 0.336, 95% CI 0.177-0.641, P=0.001) all had influence on the prognosis of ultra high-risk GTN patients. CONCLUSIONS: GTN patients with FIGO score≥12 have a poor prognosis. More emphasis should be placed on non-molar antecedent pregnancy, brain metastases, and previous multiagent chemotherapy failure. Moreover, salvage surgery may improve the prognosis. Floxuridine-based multiagent chemotherapy is effective with manageable toxicity for ultra high-risk GTN patients.

BACKGROUND: The objective of our study was to investigate the clinical characteristics and prognosis of postterm choriocarcinoma patients at Peking Union Medical College Hospital within the past 30 years. METHODS: The clinical characteristics and pertinent follow-up data of 272 patients with postterm choriocarcinoma diagnosed from December 1985 through December 2014 in our hospital were reviewed. The clinical characteristics of two cohorts cut off at 2006 were compared using χ (2) tests. Risk factors of prognosis were estimated by multivariate Cox proportional regression analysis. RESULTS: The most common initial symptom was abnormal uterine bleeding. After individualized treatment 239 patients (87.9 %) achieved complete remission, including 140 patients received initial treatment of 5-fluorouracil-based multidrug chemotherapy. There were almost no statistically significant differences in the clinical characteristics and survival rates between the two cohorts. The results of the multivariate analysis showed that history of resistance to multidrug chemotherapy, liver metastasis and FIGO score greater than 12 were independent risk factors of prognosis. CONCLUSIONS: Postterm choriocarcinoma patients were usually accompanied by several high-risk factors that should received combined chemotherapy to prevent delay in adequate treatment. 5-fluorouracil-based multidrug chemotherapy, which has been applied at PUMCH for several decades, can be an effective initial treatment for postterm choriocarcinoma patients. More emphasis should be placed on those who have history of resistance to multidrug chemotherapy, liver metastasis or a FIGO score greater than 12.

OBJECTIVE: To evaluate the efficacy and toxicity profile of floxuridine, dactinomycin, etoposide and vincristine (FAEV) regimen as primary treatment in stage IV gestational trophoblastic neoplasia (GTN). METHODS: From 2004 to 2014, FAEV was given to 30 stage IV GTNs as the primary treatment (at least two cycles) in Peking Union Medical College Hospital. Remission/resistance/recurrence rate, the cause of treatment failure, and the toxicity profile were analyzed. RESULTS: A total of 190cycles of FAEV were administered to 30 patients; the median number of the cycles was 6 (range 3-11). The median follow up was 52.3months (range 8-120). Of all the patients received FAEV primarily, 24 achieved complete remission after only received FAEV, with no recurrence; 6 patients later switched to EMA-CO treatment due to FAEV resistance. Among the 6 patients, 2 died of progressive disease after multiple lines of chemotherapy, the other 4 achieved complete remission after second-line or third-line chemotherapy and 1 of them relapsed 15months later. FAEV was well tolerated. No one died from toxicity. Severe grade 4 neutropenia and thrombocytopenia were noted in 8 (26.7%) and 2 (6.7%) cases. No secondary malignancy was observed with follow-ups from 8 to120 months. Patients treated with FAEV showed good reproductive outcomes. CONCLUSIONS: FAEV regimen might be considered as an alternative to other chemotherapy regimen in the primary treatment of stage IV GTN, where it had a high rate of remission and a tolerable toxicity.

BACKGROUND: The optimal treatment for patients with brain metastasis from gestational trophoblastic neoplasia (GTN) has not been established. This study aims to investigate the clinical characteristics and the management of brain metastasis from GTN in relation to patients' outcomes. METHODS: We retrospectively investigated 109 GTN patients with brain metastasis treated at Peking Union Medical College Hospital from January 1990 to December 2013. Patients mainly received multiagent chemotherapy with florouracil or floxuridine, dactinomycin, etoposide, and vincristine (FAEV) combined with intrathecal methotrexate with or without surgery. RESULTS: In the 109 patients, sixty-two (56.1%) patients presented for primary therapy and 47 patients had failed chemotherapy elsewhere. Eight early demise patients who died before or during first cycle of chemotherapy were excluded from analysis. The median follow-up time was 47 months (range 9-180 months). The overall 5-year survival rate (OS) was 71.1%, while the OS rate for patients receiving primary chemotherapy in our hospital was 85.5%, and this fell to 51.9% in patients with failure multidrug chemotherapy elsewhere. Multivariate analysis demonstrated that International Federation of Gynecology and Obstetrics (FIGO) scores over 12 (Hazard ratio-HR 1.279, 95% CI 1.061-1.541, P = 0.010), failure of previous multidrug chemotherapy (HR 3.177, 95% CI 1.277-7.908, P = 0.013), and concurrent renal metastasis (HR 2.654, 95% CI 1.125-6.261, P = 0.026) were the risk factors of overall survival in patients with brain metastases from GTN. CONCLUSIONS: Patients with brain metastasis from GTN have favorable outcome by multidrug chemotherapy and adjuvant therapies. Nevertheless, the prognosis is poor if the patients had previous multidrug failure chemotherapy history, concomitant with renal metastasis, or FIGO score over 12. Initial treatment with FAEV combined with intrathecal methotrexate chemotherapy can bring bright prospect to patients with brain metastases from GTN.
