An international randomized phase III trial of pulse actinomycin-D versus multi-day methotrexate for the treatment of low risk gestational trophoblastic neoplasia; NRG/GOG 275.

OBJECTIVES: Methotrexate and actinomycin-D are both effective first-line drugs for low-risk (WHO score 0-6) Gestational Trophoblastic Neoplasia (GTN) with considerable debate about which is more effective, less toxic, and better tolerated. The primary trial objective was to test if treatment with multi-day methotrexate (MTX) was inferior to pulse actinomycin-D (ACT-D). Secondary objectives included evaluation of severity and frequency of adverse events, and impact on quality of life (QOL). METHODS: This was a prospective international cooperative group randomized phase III two arm non-inferiority study (Clinical Trials Identifier: (NCT01535053). The control arm was ACT-D; the experimental arm was multi-day MTX regimen (institutional preference of 5 or 8 day). Outcome measures included complete response rate, recurrence rate, toxicity, and QOL as measured by FACT-G and FACIT supplemental items. RESULTS: The complete response rates for multi-day methotrexate and pulse actinomycin-D were 88% (23/26 patients) and 79% (22/28 patients) (p = NS) respectively, there were two recurrences in each arm, and 100% of patients survived. Significant toxicity was minimal, but mouth sores (mucositis), and eye pain were significantly more common in the MTX arm (p = 0.001 and 0.01 respectively). Quality of life showed no significant difference in overall quality of life, body image, sexual function, or treatment related side effects. The study was closed for low accrual rate (target 384, actual accrual 57), precluding statistical analysis of the primary objective. CONCLUSIONS: The complete response rate for multi-day methotrexate was higher than actinomycin-D, but did not reach statistical significance. The multi-day MTX regimens were associated with significantly more mucositis and were significantly less convenient.

Synuclein-γ in uterine serous carcinoma impacts survival: An NRG Oncology/Gynecologic Oncology Group study.

BACKGROUND: Synuclein-γ (SNCG) is highly expressed in advanced solid tumors, including uterine serous carcinoma (USC). The objective of the current study was to determine whether SNCG protein was associated with survival and clinical covariates using the largest existing collection of USCs from the Gynecologic Oncology Group (GOG-8023). METHODS: High-density tissue microarrays (TMAs) of tumor tissues from 313 patients with USC were stained by immunohistochemistry for SNCG, p53, p16, FOLR1, pERK, pAKT, ER, PR, and HER2/neu. Associations of SNCG and other tumor markers with overall and progression-free survival were assessed using log-rank tests and Cox proportional-hazards models, which also were adjusted for age, race, and stage. RESULTS: The overall survival at 5 years was 46% for women with high SNCG expression and 62% for those with low SNCG expression (log-rank P = .021; hazard ratio [HR], 1.31; 95% confidence interval [CI], 0.91-1.9 in adjusted Cox model). The progression-free survival rate at 5 years was worse for women who had high SNCG expression, at 40%, compared with 56% for those who had low SNCG expression (log-rank P = .0081; HR, 1.36; 95% CI, 0.96-1.92 in adjusted Cox model). High levels of both p53 and p16 were significantly associated with worse overall survival (p53: HR, 4.20 [95% CI, 1.54-11.45]; p16: HR, 1.95 [95% CI, 1.01-3.75]) and progression-free survival (p53: HR, 2.16 [95% CI, 1.09-4.27]; p16: HR, 1.53 [95% CI, 0.87-2.69]) compared with low levels. CONCLUSIONS: This largest collection of USCs to date demonstrates that SNCG was associated with poor survival in univariate analyses. SNCG does not predict survival outcome independent of p53 and p16 in models that jointly consider multiple markers. Cancer 2017;123:1144-1155. © 2016 American Cancer Society.

Fatal gestational trophoblastic neoplasia: An analysis of treatment failures at the Brewer Trophoblastic Disease Center from 1979-2012 compared to 1962-1978.

OBJECTIVE: To determine clinical factors that contributed to death from gestational trophoblastic neoplasia (GTN) at the Brewer Trophoblastic Disease Center from 1979-2012 compared to 1962-1978. METHODS: Nineteen women who died of GTN from 1979-2012 were retrospectively identified and compared to 45 women previously reported on who died of GTN from 1962-1978. Clinical factors analyzed included demographics, pretreatment human chorionic gonadotropin (hCG) level, duration of disease, antecedent pregnancy, number and sites of metastases, FIGO stage and score, treatment, and cause of death. RESULTS: Death from GTN occurred in 19 (4%) of 483 patients treated from 1979-2012 compared to 45 (11%) of 396 patients treated from 1962-1978 (P<0.001). Pretreatment hCG level >100,000 mIU/mL, time from pregnancy event to treatment >4 months, nonmolar antecedent pregnancy and use of surgery to control metastatic disease were similar between the two treatment eras. Patients in the recent series were more likely to have presented with FIGO IV disease or brain metastasis, been initially treated with multiagent chemotherapy, and received treatment before referral to our center compared to the earlier series. The most common causes of death from 1979-2012 and 1962-1978 were hemorrhage from one or more metastatic sites (11% vs. 42%), respiratory failure (37% vs. 31%), and multiorgan failure due to widespread chemoresistant disease (42% vs. 8%), respectively. CONCLUSIONS: Our overall survival rate in patients with gestational trophoblastic neoplasia improved from 89% in 1962-1978 to 96% in 1979-2012. More patients treated between 1979-2012 died from widespread chemoresistant disease rather than hemorrhagic complications.

Barriers to prevention: knowledge of HPV, cervical cancer, and HPV vaccinations among African American women.

OBJECTIVE: The purpose of this study was to assess knowledge of the human papillomavirus (HPV), cervical cancer, and HPV vaccination in African American women (AAW). STUDY DESIGN: This study was a quantitative cross-sectional survey of English-speaking, AAW, 18-70 years old who were recruited from a community fair in Chicago, IL. Surveys were distributed to a convenience sample to assess knowledge of HPV, cervical cancer, and the HPV vaccine. Cumulative knowledge scores were calculated for each participant, and analysis was performed to identify factors that were associated with adequate knowledge scores. RESULTS: Three hundred twenty-two surveys were distributed; 242 surveys were collected, and 215 surveys met inclusion criteria. Mean knowledge score was 12.3 ± 4.2 (mean ± SD) of a maximum score of 28 (range, 3-23); 73% of participants scored <65% on the knowledge portion of the survey. Education level (P = .007), household income (P = .010), and having a child who had been offered the HPV vaccine (P = .041) were associated with adequate (≥65% accuracy) knowledge scores. CONCLUSION: Knowledge of HPV, cervical cancer, and HPV vaccination was low in this urban African American adult female population. Targeted educational health programs are needed to increase awareness among these women who have the highest rate of cervical cancer mortality in the United States. Such patient educational programs must be developed by physicians and should address the cultural and literacy needs of this particular group of women. In addition, AAW exert influence on the health of their communities and are integral in health-related decision-making; thus, educating them through their health care providers will have far ranging impact.

Patterns of recurrence and role of pelvic radiotherapy in ovarian clear cell adenocarcinoma.

OBJECTIVE(S): The aims of this study were to analyze patterns of recurrence in patients with ovarian clear cell adenocarcinoma (CCA) and to evaluate the role of pelvic radiotherapy (RT). METHODS AND MATERIALS: All patients with ovarian CCA treated at a single institution between 1989 and 2012 were identified, and their medical records were reviewed. Eligibility criteria included histologic diagnosis of pure CCA of the ovary, surgical staging for International Federation of Gynecology and Obstetrics stage I-to-IIIC disease, and adjuvant or neoadjuvant chemotherapy. Selected end points were 3-, 5-, and 8-year cumulative incidence of pelvic recurrence (CIPR). RESULTS: Fifty-six patients met eligibility criteria. Most received intravenous carboplatin and paclitaxel for a median of 6 cycles. Six patients (10.7%) received pelvic RT, and 50 (89.3%) did not. Pelvic RT patients had stage I-to-IIC disease. Median follow-up was 39 months (range, 1-69 months). For the group as a whole, 14 patients (25%) had initial disease recurrence involving the pelvis, whereas 6 (10.7%) had first recurrence outside the pelvis. Three-, 5- and 8-year CIPR were 28.2%, 38.5%, and 43.2%, respectively. There was no significant difference in 3-, 5-, or 8-year CIPR between the group of patients receiving RT (20%, 20%, and 20%) and a group of patients with stages I to IIC who did not receive RT (9.9%, 22.4%, and 30.2%), P = 0.22. During RT, patients developed mild grade 1-to-2 side effects. After RT, 1 patient developed lower extremity lymphedema with recurrent cellulitis. One patient who developed small bowel obstruction before RT developed small bowel radiation enteritis and obstruction after RT, ultimately requiring surgical intervention. CONCLUSIONS: These findings suggest that ovarian CCA exhibits a propensity for pelvic recurrence after surgery and chemotherapy. RT, a local treatment that can effectively sterilize microscopic tumor cells, may benefit patients with this disease. Prospective studies with sufficient statistical power are warranted to further evaluate the role of RT.

Is dexamethasone associated with recurrence of ovarian cancer?

BACKGROUND: Basic science studies suggest that perioperative immune impairment may augment the risk of cancer recurrence after otherwise potentially curative surgery. Despite its immunosuppressant properties, dexamethasone is commonly given to oncologic patients in an effort to reduce postoperative nausea and vomiting. We therefore tested the hypothesis that perioperative dexamethasone administration increases the risk of ovarian cancer recurrence. METHODS: Women who had primary ovarian cytoreductive surgery between January 1997 and October 2007 were identified using a database maintained by the division of Gynecologic Oncology at Northwestern University. Tumor recurrence in women given perioperative systemic dexamethasone (4-10 mg) was compared with those who did not receive dexamethasone. The primary outcome was the propensity-matched time to cancer recurrence. Recurrence was defined by a carcinoantigen 125 >21 U/mL or computerized tomography evidence of the disease followed by tissue confirmation. Median difference and 95% confidence interval between the propensity-matched groups were calculated using a 10,000 sample bootstrap. RESULTS: Among 260 women having primary cytoreductive surgery for ovarian cancer that met our inclusion criteria, 102 subjects were given perioperative systemic dexamethasone. Cancer recurrence was observed in 178 subjects, and the overall unadjusted median (IQR) time to recurrence was 18 (7-50) months. Eighty-seven cases and 87 controls were propensity matched to adjust for confounding covariates. After propensity matching the groups for confounding covariates, the median (IQR) time to recurrence in the dexamethasone group was 23 (6-46) compared with 18 (8-53) months in the control group (P = 0.63) with a median (95% confidence interval) difference of time to recurrence between the dexamethasone and the control group of 5 (-8 to 17) months. CONCLUSION: We could not find evidence for an association between perioperative systemic dexamethasone administration and ovarian cancer recurrence after primary cytoreductive surgery. Our results do not support avoiding low-dose perioperative dexamethasone for prevention of postoperative nausea, vomiting, and pain in ovarian cancer patients.

Hepatic metastasis in gestational trophoblastic neoplasia: patient characteristics, prognostic factors, and outcomes.

OBJECTIVE: To identify patient characteristics, determine prognostic factors, and evaluate outcomes for women with hepatic metastases in gestational trophoblastic neoplasia (GTN). STUDY DESIGN: Seventeen GTN patients with hepatic metastases were treated at our institution between 1962 and 2010. Demographic data, disease characteristics, and survival were all analyzed retrospectively. Fisher's exact test was used to determine significance. RESULTS: The median age was 29 years (range, 16-48), and the antecedent pregnancy was nonmolar in 12 patients (75%) and a hydatidiform mole in 4 patients (25%). Fifteen patients (88%) had metastatic disease outside the liver, including lung (13), brain (5), and other intraabdominal organs (8). Median FIGO score was 14 (range, 12-19). Chemotherapy consisted of single-agent methotrexate or actinomycin D in 2 patients; methotrexate, actinomycin D, cyclophosphamide (MAC) in 4 patients; and etoposide, methotrexate, actinomycin D, cyclophosphamide and vincristine (EMACO) in 11 patients. Complete response rate to chemotherapy was 82% for EMA-CO versus 17% for other types of chemotherapy (p = 0.035). Overall survival was 41% (7/17). CONCLUSION: Survival of patients with GTN and hepatic metastases increased from 17% (1/6) to 55% (6/11) after 1986 when EMA-CO chemotherapy was introduced. Survival was significantly decreased for patients with concomitant intraabdominal or brain metastases (11% vs. 75%, p = 0.015).

Radiation Therapy With or Without Cisplatin for Local Recurrences of Endometrial Cancer: Results From an NRG Oncology/GOG Prospective Randomized Multicenter Clinical Trial.

PURPOSE: Pelvic recurrence is a frequent pattern of relapse for women with endometrial cancer. A randomized trial compared progression-free survival (PFS) after treatment with radiation therapy alone as compared with concurrent chemotherapy. MATERIALS AND METHODS: Between February 2008 and August 2020, 165 patients were randomly assigned 1:1 to receive either radiation treatment alone or a combination of chemotherapy and radiation treatment. The primary objective of this study was to determine whether chemoradiation therapy was more effective than radiation therapy alone at improving PFS. RESULTS: The majority of patients had low-grade (1 or 2) endometrioid histology (82%) and recurrences confined to the vagina (86%). External beam with either the three-dimensional or intensity modulated radiation treatment technique was followed by a boost delivered with brachytherapy or external beam. Patients randomly assigned to receive chemotherapy were treated with once weekly cisplatin (40 mg/m2). Rates of acute toxicity were higher in patients treated with chemoradiation as compared with radiation treatment alone. Median PFS was longer for patients treated with radiation therapy alone as compared with chemotherapy and radiation (median PFS was not reached for RT v 73 months for chemoradiation, hazard ratio of 1.25 (95% CI, 0.75 to 2.07). At 3 years, 73% of patients treated definitively with radiation and 62% of patients treated with chemoradiation were alive and free of disease progression. CONCLUSION: Excellent outcomes can be achieved for women with localized recurrences of endometrial cancer when treated with radiation therapy. The addition of chemotherapy does not improve PFS for patients treated with definitive radiation therapy for recurrent endometrial cancer and increases acute toxicity. Patients with low-grade and vaginal recurrences who constituted the majority of those enrolled are best treated with radiation therapy alone.

A prospective study evaluating the clinical relevance of a chemoresponse assay for treatment of patients with persistent or recurrent ovarian cancer.

OBJECTIVE: Use of in vitro chemoresponse assays for informing effective treatment selection is a compelling clinical question and a topic of debate among oncologists. A prospective study was conducted evaluating the use of a chemoresponse assay in recurrent ovarian cancer patients. METHODS: Women with persistent or recurrent ovarian cancer were enrolled under an IRB-approved protocol, and fresh tissue samples were collected for chemoresponse testing. Patients were treated with one of 15 protocol-designated treatments empirically selected by the oncologist, blinded to the assay results. Each treatment was classified by the assay as: sensitive (S), intermediate (I), or resistant (R). Patients were prospectively monitored for progression-free survival (PFS) and overall survival (OS). Associations of assay response for the physician-selected treatment with PFS and OS were analyzed. RESULTS: A total of 262 evaluable patients were enrolled. Patients treated with an assay-sensitive regimen demonstrated significantly improved PFS and OS while there was no difference in clinical outcomes between I and R groups. Median PFS was 8.8 months for S vs. 5.9 months for I+R (hazard ratio [HR]=0.67, p=0.009). The association with assay response was consistent in both platinum-sensitive and platinum-resistant tumors (HR: 0.71 vs. 0.66) and was independent of other covariates in multivariate analysis (HR=0.66, p=0.020). A statistically significant14-month improvement in mean OS (37.5 months for S vs. 23.9 months for I+R, HR=0.61, p=0.010) was demonstrated. CONCLUSIONS: This prospective study demonstrated improved PFS and OS for patients with either platinum-sensitive or platinum-resistant recurrent ovarian cancer treated with assay-sensitive agents.

Ovarian cancer, version 2.2013.

These NCCN Guidelines Insights focus on the major updates to the 2013 NCCN Guidelines for Ovarian Cancer. Four updates were selected based on recent important updates in the guidelines and on debate among panel members about recent clinical trials. The topics include 1) intraperitoneal chemotherapy, 2) CA-125 monitoring for ovarian cancer recurrence, 3) surveillance recommendations for less common ovarian histopathologies, and 4) recent changes in therapy for recurrent epithelial ovarian cancer. These NCCN Guidelines Insights also discuss why some recommendations were not made.

Treatment of nonmetastatic and metastatic low-risk gestational trophoblastic neoplasia: factors associated with resistance to single-agent methotrexate chemotherapy.

OBJECTIVE: To determine factors associated with resistance to methotrexate treatment of low-risk gestational trophoblastic neoplasia (GTN). METHODS: We reviewed the records of 358 patients with low-risk GTN (FIGO stage I and stages II-III, score<7) treated initially with methotrexate 0.4 mg/kg (max 25mg) IV push daily × 5 days every 14 days between 1979 and 2009. Actinomycin D 0.5mg IV push daily × 5 days every 14 days was used in 64 patients who developed resistance or toxicity to initial methotrexate chemotherapy, and combination drug regimens were used in 20 patients who failed single-agent chemotherapy. Adjuvant surgery was used in 34 selected patients. Clinical response and survival as well as factors affecting outcomes were analyzed retrospectively. RESULTS: The complete response rate to initial methotrexate chemotherapy was 81% (290/358) and the complete response rate to actinomycin D as secondary therapy was 75% (48/64), for an overall complete response rate to sequential single-agent chemotherapy of 94% (338/358). The remaining 20 patients (6%) were all placed into permanent remission with the use of multiagent chemotherapy with or without surgery. Resistance to initial methotrexate chemotherapy was associated with increasing FIGO score (p<.0001), clinicopathologic diagnosis of choriocarcinoma (p=.028), higher pretreatment hCG (p=0.001) and presence of metastatic, disease (p=.018). CONCLUSIONS: Sequential single-agent chemotherapy with methotrexate (0.4 mg/kg-max 25mg) followed by actinomycin D (0.5mg) each given IV push for 5 consecutive days every other week for treatment of low-risk GTN resulted in only 6% of patients requiring multiagent chemotherapy and a 100% survival rate.

Importance of salvage therapy in the management of high-risk gestational trophoblastic neoplasia.

OBJECTIVE: To assess the value of secondary therapy in the management of high-risk gestational trophoblastic neoplasia (GTN) after failure of initial multiagent chemotherapy. STUDY DESIGN: Forty-nine women with high-risk GTN, including 29 who were treated primarily and 20 who were treated secondarily, completed treatment at the Brewer Trophoblastic Disease Center between 1986 and 2010. Initial chemotherapy consisted of etoposide, high-dose methotrexate with folinic acid, actinomycin D, cyclophosphamide and vincristine (EMA-CO) in 29 patients who were treated primarily and in 10 patients who had received single-agent chemotherapy before being treated at our center. Patients who had incomplete responses or developed resistance to EMA-CO or had previously received EMA-CO were treated with drug combinations employing etoposide and a platinum agent with methotrexate and actinomycin D (EMA-EP), bleomycin (BEP), ifosfamide (VIP, ICE) or paclitaxel (TP/TE). Adjuvant surgery and brain radiation were used in selected patients. Clinical response and survival as well as factors affecting outcomes were analyzed retrospectively. RESULTS: Twenty-eight (57%) of the 49 patients developed resistance to EMA-CO: 13 (45%) of 29 treated primarily and 15 (75%) of 20 treated secondarily. Of the 13 patients who failed primary treatment with EMA-CO, 10 (77%) had lasting complete responses to EMA-EP (4), BEP (3), VIP (1), ICE (1) or TP/TE (1). Of the 15 patients who failed EMA-CO used as secondary therapy, 13 (87%) had lasting complete responses to EMA-EP (5), BEP (6) or ICE (2). Brain irradiation was given to 4 patients who developed brain metastases during treatment, 3 of whom survived. Operative procedures were performed to remove resistant foci of disease in the lungs (9) or uterus (2) in 11 (39%) of the 28 patients, 9 (82%) of whom survived. Survival was significantly influenced by hCG level at the start of salvage therapy (p<0.001), number of metastatic sites (p <0.02) and metastases to sites other than the lung and vagina (p<0.05). CONCLUSION: Salvage therapy with platinum/etoposide-based drug regimens, often in conjunction with surgery and brain radiation, was successful in achieving cure in 82% of 28 high-risk GTN patients who failed initial multiagent chemotherapy and was ultimately responsible for survival in 53% of the 43 patients (88%) with high-risk GTN who were cured.

Actinomycin D for methotrexate-failed low-risk gestational trophoblastic neoplasia.

OBJECTIVE: To determine outcomes and factors associated with failure of 5-day actinomycin D for treatment of methotrexate-failed low-risk gestational trophoblastic neoplasia (GTN). STUDY DESIGN: We reviewed the records of 358 patients treated with methotrexate 0.4 mg/kg (max 25 mg) IV push q.d. x 5 d every 14 d for FIGO-defined, low-risk GTN between 1979 and 2009. Actinomycin D 0.5 mg IV push q.d. x 5 d every 14 d was given to 64 of 68 patients (18%) who failed methotrexate: 48 (75%) for resistance and 16 (25%) for toxicity. Adjuvant surgery was used in selected patients. Clinical response and survival as well as factors affecting outcomes were analyzed retrospectively. RESULTS: The complete response rate to secondary chemotherapy with actinomycin D for failed methotrexate treatment of low-risk GTN was 75% (48/64), including 71% (34/48) for methotrexate resistance and 88% (14/16) for methotrexate toxicity. All 20 patients (6%) who failed sequential single-agent chemotherapy with methotrexate and actinomycin D were placed into permanent remission with the use of multiagent chemotherapy with or without surgery. The only factor significantly associated with resistance to secondary actinomycin D chemotherapy was clinicopathologic diagnosis of choriocarcinoma versus postmolar GTN (56% versus 20%, p = 0.025). CONCLUSION: Actinomycin D 0.5 mg IV q.d. x 5 d every 14 d used as secondary therapy in methotrexate-failed low-risk GTN resulted in a 75% complete response rate and eventual 100% cure with subsequent multiagent chemotherapy with or without surgery. Resistance to sequential methotrexate and actinomycin D chemotherapy was significantly associated with original FIGO score > or = 3 and clinicopathologic diagnosis of choriocarcinoma.

Brain metastasis in gestational trophoblastic neoplasia: an update.

OBJECTIVE: To update the treatment of brain metastases in gestational trophoblastic neoplasia (GTN) at the Brewer Trophoblastic Disease Center, comparing treatment and outcomes from 1995-2009 with those from 1962-1994. STUDY DESIGN: Thirty-seven patients with GTN who had brain metastases at presentation (25, 68%) or who developed brain metastases during treatment (12, 32%) were treated with chemotherapy and brain irradiation at the Brewer Center between 1962 and 2009 (26 prior to 1995 and 11 since 1995). Patients underwent whole brain irradiation (2400-4000 cGy in 200-300 cGy fractions prior to 1995, and 2400-3000 cGy in 200 cGy fractions since 1995) +/- radiosurgery. RESULTS: Of 11 patients with GTN treated for brain metastases since 1995, 7 (64%) are alive, and 4 died. Six (55%) of the 11 patients treated after 1995 were diagnosed with brain metastases during treatment, 3 (50%) of whom were cured, compared to 6 (23%) of the 26 patients treated before 1995, only 1 (17%) of whom was cured. CONCLUSION: The overall survival for all 37 patients with GTN who had brain metastases from 1962-2009 was 51% (19/37): 46% (12/26) before 1995 and 64% (7/11) after 1995. Survival was significantly influenced by symptoms at presentation: 100% (8/8) for asymptomatic patients versus 41% (7/17) for symptomatic patients (p=0.0005). No patient who died had uncontrolled brain metastases. In our experience, therefore, brain metastases in GTN are curable with a combination of systemic multiagent chemotherapy and whole brain irradiation.

Survival and reproductive outcomes in women treated for malignant ovarian germ cell tumors.

OBJECTIVE: The objective of this study is to review all malignant germ-cell tumors (MOGCTs) treated at our institution, focusing on reproductive outcomes and menstrual function of patients treated with fertility-sparing surgery and adjuvant chemotherapy. METHODS: We performed a retrospective chart review of patients treated for MOGCTs between January 1, 1979 and March 31, 2008. Charts of identified patients were abstracted and data were collected. Patients who had fertility-sparing surgery were contacted and a telephone questionnaire was performed to gather reproductive and menstrual history. RESULTS: Forty patients were treated for MOGCTs at our institution. Mean age at the time of diagnosis was 26.5years (range, 10-48years). Histologic subtypes were: immature teratoma (52.5%), dysgerminoma (27.5%), yolk sac tumor (10.0%), mixed germ cell tumor (7.5%), and choriocarcinoma (2.5%). Thirty-five percent of tumors were FIGO stages II-IV. Twenty-seven patients (67.5%) were treated with chemotherapy postoperatively, 23 (85%) of whom received bleomycin, etoposide and cisplatin (BEP). There were three recurrences, but no deaths. Fertility-sparing surgery was performed in 22 patients (55%), 16 of whom received adjuvant chemotherapy. Fourteen of these patients were contacted. Of the 10 remaining patients desiring pregnancy, 8 (80%) had 11 successful spontaneous pregnancies, one required in-vitro fertilization, and the other required donor egg in-vitro fertilization, resulting in 14 live births. All 14 patients had normal menstrual cycles within one year of completing chemotherapy. CONCLUSIONS: Overall survival was 100% among patients with both local and advanced MOGCTs, including those who underwent fertility-sparing surgery. Fertility-sparing surgery plus adjuvant chemotherapy appeared to have little or no effect on fertility or menstrual cycles.

Point: chemosensitivity assays have a role in the management of recurrent ovarian cancer.

In this era of personalized medicine, patients with recurrent ovarian cancer deserve better than the 25% response rate that is associated with drugs selected based on clinical information alone. In the past decade, marked laboratory improvements have enabled chemosensitivity assay testing to yield a 0.70 correlation with response, and to accurately predict progression-free and overall survival. Compelling retrospective data supporting the use of this technology cannot be ignored while waiting for a cooperative group to test whether chemosensitivity assay should be used to direct salvage therapy.

Management of metastatic high-risk gestational trophoblastic neoplasia: FIGO stages II-IV: risk factor score > or = 7.

OBJECTIVE: To evaluate treatment of metastatic high-risk gestational trophoblastic neoplasia (GTN), including durable complete response rates to chemotherapy, factors affecting response to therapy, and overall survival. STUDY DESIGN: Forty women with metastatic high-risk GTN (International Federation of Gynecology and Obstetrics [FIGO] stages II-IV, score > or = 7) completed treatment between 1986 (when EMA-CO became the standard chemotherapy for high-risk disease) and 2009, including 26 who were treated primarily and 14 who were treated secondarily. Patients who had incomplete responses or developed resistance to EMA-CO or other methotrexate-containing regimens were treated with drug combinations employing etoposide and a platinum agent with or without bleomycin or ifosfamide. Adjuvant radiotherapy and surgery were used in selected patients. Clinical response and survival as well as factors affecting outcomes were analyzed retrospectively. RESULTS: The overall survival rate was 90% (36 of 40): 92% (24/26) for primary treatment and 86% (12/14) for secondary treatment. Twenty-one patients (53%) had durable complete clinical responses to initial treatment, 15 patients (37%) developed resistance to initial chemotherapy but were subsequently placed into lasting remission with platinum-based chemotherapy with or without surgery and 4 patients (10%) died of widespread metastatic disease. Durable complete clinical response to initial chemotherapy was significantly influenced by FIGO stage (II and III, 63%, vs. IV, 31%, p = 0.05) and risk factor score (< 12, 71%, vs. > or = 12, 32%, p < 0.02). Survival was also significantly associated with both FIGO stage (II and III, 100%, vs. IV, 69%, p < 0.01) and score (< 12, 100%, vs. > or = 12, 79%, p < 0.05). CONCLUSION: The use of EMA-CO chemotherapy as primary treatment and platinum-based chemotherapy along with surgical excision of resistant disease as secondary treatment for patients with metastatic high-risk GTN resulted in a survival rate of 90%. All patients who died had FIGO stage IV and risk factors scores > or = 12.

Cetuximab in Patients with Breast Cancer, Non-Small Cell Lung Cancer, and Ovarian Cancer Without KRAS, NRAS, or BRAF Mutations: Results from the Targeted Agent and Profiling Utilization Registry (TAPUR) Study.

BACKGROUND: The Targeted Agent and Profiling Utilization Registry (TAPUR) Study, a phase II basket study, evaluates anti-tumor activity of commercially available targeted agents in patients with advanced cancers harboring genomic alterations known as drug targets. OBJECTIVE: With no known genomic targets predictive of sensitivity to cetuximab, cetuximab was evaluated in patients with breast cancer (BC), non-small cell lung cancer (NSCLC), and ovarian cancer (OC), without KRAS, NRAS, or BRAF mutations. PATIENTS AND METHODS: Eligible patients with advanced BC, NSCLC, and OC received a cetuximab loading dose, then weekly infusions (250 mg/m2 over 60 min). A Simon two-stage design, requiring ten patients in stage I, was employed per each disease-specific cohort. The primary endpoint was disease control (objective response or stable disease for at least 16 weeks). If two or more patients in stage I achieved disease control, the cohort would enroll 18 more patients in stage II. Power and alpha of the design are 85% and 10%, respectively. Secondary endpoints included progression-free survival, overall survival, and safety. RESULTS: Patients with BC (n = 10), NSCLC (n = 10), and OC (n = 29) were enrolled between June 2016 and September 2018. No objective responses or stable disease for at least 16 weeks were observed in the BC and NSCLC cohorts. No objective responses and four patients with stable disease for at least 16 weeks were observed in the OC cohort. Six of 49 patients reported grade 3 or higher adverse events or serious adverse events at least possibly related to cetuximab. CONCLUSIONS: Cetuximab does not have clinical activity in patients with advanced BC, NSCLC, and OC without KRAS, NRAS, or BRAF mutations. CLINICAL TRIAL REGISTRATION: NCT02693535 (26 February, 2016).

Robotic surgery in gynecologic oncology: impact on fellowship training.

OBJECTIVES: To report the impact of a new robotic surgery program on the surgical training of gynecologic oncology fellows over a 12 month period of time. METHODS: A robotic surgery program was introduced into the gynecologic oncology fellowship program at Northwestern University Feinberg School of Medicine in June 2007. A database of patients undergoing surgical management of endometrial and cervical cancer between July 2007 and July 2008 was collected and analyzed. Changes in fellow surgical training were measured and analyzed. RESULTS: Fellow surgical training for endometrial and cervical cancer underwent a dramatic transition in 12 months. The proportion of patients undergoing minimally invasive surgery increased from 3.3% (4/110 patients) to 43.5% (47/108 patients). Fellow training transitioned from primarily an open approach (94.4%) to a minimally invasive approach (11% laparoscopic, 49% robotic, 40% open) for endometrial cancer stagings, and from an open approach (100%) to an open (50%) and robotic (50%) approach for radical hysterectomies. Fellow participation in robotic procedures increased from 45% in the first 3 months to 72% within 6 months, and 92% by 12 months. The role of the fellow in robotic cases transitioned from bedside assistant to console operator within 3 months. CONCLUSIONS: Fellow surgical training underwent a dramatic change with the introduction of a robotic surgery program. The management of endometrial and cervical cancer was impacted the most by robotics. Robotic surgery broadened fellowship surgical training, but balanced surgical training and standardized fellow training modules remain challenges for fellowship programs.

FIGO stage IIIC endometrial carcinoma: prognostic factors and outcomes.

OBJECTIVES: Investigate the clinicopathologic characteristics, nodal distribution, and postoperative treatment of patients with FIGO stage IIIC endometrial carcinoma and determine patterns of recurrence and survival. METHODS: A retrospective review of 85 patients who underwent surgical staging with lymph node dissection at a single institution between 1979 and 2005 was performed. Data collected from patient charts included demographics, treatment, recurrence and survival. Variables were compared using the log-rank and X2 tests, and multivariate analysis was performed. RESULTS: Of 1487 patients who underwent surgical staging for endometrial cancer, 104 (7.0%) were diagnosed with stage IIIC disease and 85 of these were analyzed. Stage was determined by positive pelvic lymph nodes (PLN) in 54 patients, and positive para-aortic lymph nodes (PaLN)+/-PLN in 31 patients. With a median follow up of 50 months, 5-year overall survival (OS) was 61.3%, recurrence-free survival (RFS) was 58.0%, and disease-specific survival (DSS) was 71.9%. Median OS, RFS and DSS were 131 months, 131 months, and not attained, respectively. Five-year OS and RFS with positive PaLN were 48.8% and 44.4% respectively, compared to 69.7% and 65.6% with positive PLN only. On multivariate analysis, age, non-endometrioid histology, and >50% invasion were significantly associated with OS; age and non-endometrioid histology were associated with RFS. Disease recurred in 21 patients (24.7%): 15 distant, 4 abdominal, 1 para-aortic, and 1 pelvic. Disease recurred outside the field of radiation in all patients. CONCLUSIONS: Endometrial cancer patients with FIGO stage IIIC had a 5-year OS of 61.3%, a RFS of 58.0% and a DSS of 71.9% in this series. Because of the high proportion of distant sites of recurrence (71.4%), recurrence outside the radiation field (100%), and mortality after recurrence (86.3%), multimodality therapy should be considered.
