RESUMO

OBJECTIVES: To evaluate differences in survival and recurrence patterns in stage I-IV uterine carcinosarcoma patients treated with surgery followed by adjuvant chemotherapy alone, radiation alone, or a combination of both chemotherapy and radiation therapy. METHODS: A multicenter retrospective analysis of patients with surgically staged carcinosarcoma receiving adjuvant therapy from January 2000 to December 2019 was conducted. Inclusion criteria were patients with carcinosarcoma who had received primary surgical treatment, followed by adjuvant therapy with chemotherapy alone, radiation therapy alone, or a combination of chemoradiation. Patients were excluded for incomplete surgical staging data, adjuvant brachytherapy alone, adjuvant chemotherapy and brachytherapy without external beam radiation therapy, receipt of neoadjuvant chemotherapy and/or pre-operative pelvic radiation, and death due to non-cancer causes. Sites of recurrence were analyzed by adjuvant treatment modality using Pearson's χ2 test. Progression-free and overall survival were calculated using Kaplan-Meier estimates. Multivariate analysis was performed using Cox proportional hazards model. RESULTS: Of 176 evaluable patients, 27% (n=47) had stage I, 14% (n=24) stage II, 37% (n=66) stage III, and 22% (n=39) stage IV disease. Among them, 33% (n=59) received chemotherapy alone, 17% (n=29) received radiation therapy alone, and 50% (n=88) received chemoradiation. Patients with stage I disease recurred less frequently (64%) versus stage II (83%), stage III (85%), and stage IV (90%) (p<0.001). Stage I disease demonstrated improved progression-free and overall survival relative to all other stages (p<0.01). Across all stages, patients receiving chemoradiation experienced superior progression-free (p=0.01) and overall survival (p=0.05) versus single modality therapy. However, when analyzed in a stage-specific manor, stage III disease derived the greatest survival benefit from chemoradiation versus all other stages (p<0.01). On multivariant analysis, only stage and receipt of chemoradiation were independent predictors of survival. CONCLUSION: Stage I disease demonstrated improved survival compared with other stages regardless of adjuvant treatment modality. Chemoradiation was associated with improved survival and better distant and local disease control for all stages of disease. Patients with stage III disease derived the most benefit from chemoradiation.

RESUMO

BACKGROUND: New York City (NYC) emerged as an epicenter of the COVID-19 pandemic, and marginalized populations were affected at disproportionate rates. The authors sought to determine the impact of COVID-19 on cancer treatment, anxiety, and financial distress among low-income patients with gynecologic cancer during the peak of the NYC pandemic. METHODS: Medicaid-insured women who were receiving gynecologic oncology care at 2 affiliated centers were contacted by telephone interviews between March 15 and April 15, 2020. Demographics and clinical characteristics were obtained through self-report and retrospective chart review. Financial toxicity, anxiety, and cancer worry were assessed using modified, validated surveys. RESULTS: In total, 100 patients completed the telephone interview. The median age was 60 years (range, 19-86 years), and 71% had an annual income <$40,000. A change in employment status and early stage cancer (stage I and II) were associated with an increase in financial distress (P < .001 and P = .008, respectively). Early stage cancer and telehealth participation were significantly associated with increased worry about future finances (P = .017 and P = .04, respectively). Lower annual income (<$40,000) was associated with increased cancer worry and anxiety compared with higher annual income (>$40,000; P = .036 and P = .017, respectively). When controlling for telehealth participation, income, primary language, and residence in a high COVID-19 prevalence area, a delay in medical care resulted in a 4-fold increased rate of anxiety (P = .023, 95% CI, 1.278-14.50). Race was not significantly associated with increased financial distress, cancer worry, or anxiety. CONCLUSIONS: Low socioeconomic status was the most common risk factor for increased financial distress, cancer worry, and anxiety. Interventions aimed at improving access to timely oncology care should be implemented during this ongoing pandemic.

RESUMO

BACKGROUND: New York City was among the epicenters during the COVID-19 pandemic. Oncologists must balance plausible risks of COVID-19 infection with the recognized consequences of delaying cancer treatment, keeping in mind the capacity of the health care system. We sought to investigate treatment patterns in gynecologic cancer care during the first two months of the COVID-19 pandemic at three affiliated New York City hospitals located in Brooklyn, Manhattan and Queens. METHODS: A prospective registry of patients with active or presumed gynecologic cancers receiving inpatient and/or outpatient care at three affiliated New York City hospitals was maintained between March 1 and April 30, 2020. Clinical and demographic data were abstracted from the electronic medical record with a focus on oncologic treatment. Multivariable logistic regression analysis was explored to evaluate the independent effect of hospital location, race, age, medical comorbidities, cancer status and COVID-19 status on treatment modifications. RESULTS: Among 302 patients with gynecologic cancer, 117 (38.7%) experienced a COVID-19-related treatment modification (delay, change or cancellation) during the first two months of the pandemic in New York. Sixty-four patients (67.4% of those scheduled for surgery) had a COVID-19-related modification in their surgical plan, 45 (21.5% of those scheduled for systemic treatment) a modification in systemic treatment and 12 (18.8% of those scheduled for radiation) a modification in radiation. Nineteen patients (6.3%) had positive COVID-19 testing. On univariate analysis, hospital location in Queens or Brooklyn, age ≤65 years, treatment for a new cancer diagnosis versus recurrence and COVID-19 positivity were associated with treatment modifications. On multivariable logistic regression analysis, hospital location in Queens and COVID-19 positive testing were independently associated with treatment modifications. CONCLUSIONS: More than one third of patients with gynecologic cancer at three affiliated New York City hospitals experienced a treatment delay, change or cancellation during the first two months of the COVID-19 pandemic. Among the three New York City boroughs represented in this study, likelihood of gynecologic oncology treatment modifications correlated with the case burden of COVID-19.

RESUMO

OBJECTIVES: Uterine carcinosarcoma is a rare, aggressive form of uterine cancer with a high recurrence rate and poor survival at all stages. We sought to evaluate the outcomes of patients treated with chemotherapy versus a combination of chemotherapy and radiation (chemoradiation) to determine survival. METHODS: A multicenter retrospective analysis of patients with stage I-IV carcinosarcoma was conducted from January 2000 to December 2017. Inclusion criteria were primary surgical management, defined as hysterectomy ± salpingo-oophorectomy, comprehensive surgical staging and/or tumor debulking, followed by adjuvant chemotherapy or chemoradiation. Differences in the frequencies of stage, cytoreduction status, treatment delays and sites of disease recurrence were identified using Pearson's χ2 test. Progression-free and overall survival rates were calculated using Kaplan-Meier estimates. RESULTS: Final analysis included 148 patients; 40.5% (n=60) chemotherapy and 59.5% (n=88) chemoradiation. The mean age was 67 years (range 39-89). Stage distribution included 24.3% stage I, 12.2% stage II, 37.2% stage III, and 26.3% stage IV. There was no difference in the frequency of stage (p=0.81), cytoreduction status (p=0.61), treatment delays (p=0.57), or location of recurrence (p=0.97) between cohorts. The most frequent location of recurrence was the abdomen (50.0%). The median progression-free survival favored chemoradiation over chemotherapy (15 vs 11 months, respectively), as did the median overall survival (26 vs 20 months, respectively). Chemoradiation was associated with a statistically significant improvement in 2 year progression-free survival (22.5% vs 13.6%; p=0.006) and 2 year overall survival (50.0% vs 35.6%; p=0.018) compared with chemotherapy alone. On subanalysis of patients receiving chemoradiation, 'sandwich sequencing' (chemotherapy-radiation-chemotherapy) was associated with superior overall survival compared with alternate therapy sequences (chemotherapy-radiation and radiation-chemotherapy) (34 months vs 14 months and 14 months, respectively) (p=0.038). CONCLUSIONS: Chemoradiation was associated with improvement in both progression-free and overall survival for all stages of carcinosarcoma compared with chemotherapy alone.

RESUMO

We investigated genetic counseling and testing rates for patients with gynecologic malignancy at a tertiary care center with a large minority population. Our retrospective cohort included newly diagnosed epithelial ovarian, fallopian tube, peritoneal, or endometrial cancer patients between January 2014 and June 2022. For endometrial cancer, 373 patients were identified. A total of 207 (55%) patients were screened using mismatch repair immunohistochemistry (MMR IHC). A total of 82 (40%) had MMR deficiencies on IHC. Of these, 63 (77%) received genetic counseling. A total of 62 (98%) underwent genetic testing, and ultimately, 7 (11%) were diagnosed with Lynch syndrome (LS). The overall rate of LS was 1.9%. MMR IHC testing increased steadily, reaching 100% in 2022. For ovarian cancer, 144 patients were identified. A total of 104 (72%) patients received genetic counseling, and 99 (95%) underwent genetic testing. Rates were not influenced by race, ethnicity, insurance type, or family history of cancer. They were significantly different by cancer stage (p < 0.01). The proportion of patients who received genetic counseling increased from 47% in 2015 to 100% in 2022 (p < 0.01). Most counseling was performed by a gynecologic oncologist (93%) as opposed to a genetic counselor (6.7%). Overall, 12 (8.3%) patients were BRCA+. High rates of counseling and testing were observed with few disparities.

RESUMO

OBJECTIVES: The prognosis of patients presenting with stage IVB uterine serous carcinoma (USC) remains extremely poor, with a reported 5-year survival of <20%. Here were evaluate the survival impact of cytoreductive surgery and identify other prognostic factors in stage IVB USC. METHODS: A multicenter retrospective analysis of patients with stage IVB USC was conducted from 2000 to 2018. Inclusion criteria were patients who had undergone comprehensive surgical staging/tumor debulking; followed by adjuvant chemotherapy+/-external beam radiation therapy (EBRT). Optimal cytoreduction (R1) was defined as residual disease ≤1 cm at completion of surgery, and suboptimal cytoreduction (R2) was defined as >1 cm. Progression free survival (PFS) and overall survival (OS) analysis was performed using Kaplan-Meier estimates. Multivariate analysis (MVA) was performed using Cox proportional hazards model. RESULTS: Final analysis included 68 patients. There was no difference in the frequency of treatment delays between regimens (p = 0.832). 96% of patients received platinum-based chemotherapy. There was no difference in the age (p = 0.227), race (p = 0.936), type of radiotherapy (p = 0.852) or chemotherapy regimen received (p = 0.996) between R1 and R2 cohorts. The median PFS for all patients was 8 months and the median OS was 13 months. Cytoreduction to R1 was associated with a median PFS of 9 months, compared to R2 with a median PFS of 4 months (p < 0.001, HR 0.32, 95% CI 7.4-14.1). Median OS was also improved with R1 vs. R2 cytoreduction (17 months vs. 7 months, respectively) (p < 0.001, HR 0.21, 95% CI 13.7-26.4). Compared to R1, cytoreduction to R0 was not associated with a survival benefit. The R0 median OS was 17 months versus 18 months in R1 (p = 0.67). The combination of adjuvant chemoradiation was associated with improved PFS (11 months vs. 7 months) (p = 0.024, HR 0.41, 95% CI 6.5-9.4) and OS (22 months vs 13 months) (p = 0.65, HR 0.25, 95% CI 10.5-15.4) compared to chemotherapy-alone, respectively. On MVA, only the amount of residual disease (p = 0.003, HR 0.39, 95% CI 0.2-0.7) and receipt of adjuvant chemoradiation (p = 0.010, HR 0.09, 95% CI 0.01-0.58) were independent predictors of survival. CONCLUSIONS: In stage IVB USC, optimal cytoreduction should be the goal at the time of primary surgery. The combination of chemoradiation was associated with superior survival compared to chemotherapy alone and should be further investigated in this patient population.

RESUMO

BACKGROUND: We seek to evaluate the difference in recurrence patterns and survival among stage IIIC high-grade endometrial cancer treated with surgery followed by adjuvant chemotherapy alone, radiation therapy alone, or both (chemoradiation). METHODS: A multicenter retrospective analysis of surgically staged IIIC HGEC receiving adjuvant therapy was conducted. HGEC was defined as grade 3 endometrioid adenocarcinoma, serous, clear cell and carcinosarcoma. Differences in the frequency of recurrence sites and treatment delays were identified using Pearson's χ2 test. Progression-free survival (PFS) and overall survival (OS) were calculated using Kaplan-Meier estimates. RESULTS: A total of 155 patients were evaluable: 41.9% carcinosarcoma, 36.8% serous, 17.4% grade 3 and 3.9% clear cell. Of these, 67.1% received chemoradiation, 25.8% received chemotherapy and 7.1% received radiation therapy. There was no difference in the frequency of treatment delays between regimens (p = 0.571). There was a trend towards greater retroperitoneal recurrence with chemotherapy (25.9%) versus chemoradiation (8.4%) and radiation therapy (7.7%) (p = 0.252). Grade 3 tumors had improved progression-free and overall survival (26 and 42 months, respectively) versus serous (17 and 30 months, respectively), carcinosarcoma (14 and 24 months, respectively) and clear cell (24 and 30 months respectively) (p = 0.002, p < 0.001). Overall, chemoradiation was superior to chemotherapy and radiation therapy in PFS (p < 0.001) and OS (p < 0.001). Upon multivariate analysis, only histology and receipt of chemoradiation were independent predictors of survival. CONCLUSION: The majority of stage IIIC high-grade endometrial carcinomas recurred. Chemoradiation was associated with improved survival and less retroperitoneal recurrence. Grade 3 tumors demonstrated improved survival versus other histologies regardless of adjuvant treatment modality.

RESUMO

Metastasis to bone (BM) is an uncommon manifestation of advanced endometrial cancer (EC). The present study will review the clinicopathologic features of a cohort of patients with EC and BM. We conducted a multi-center retrospective review of patients with EC and BM. Demographic and clinical information was extracted from the medical records. Survival outcomes were determined using Kaplan-Meier Curves. Final analysis included 10 patients. The median age was 65 years (range 31-71). 80% had FIGO stage III/IV disease. The most common site of BM was the spine (66%). All patients presented with extraosseous dissemination at the time of diagnosis of BM and 70% were found to have multiple sites of BM. 80% of patients were diagnosed with BM in the recurrent setting. The median time to diagnosis of bone recurrence was 14 months (range: 0-44). Median survival after diagnosis of BM was 11 months (range: 1-22 months). Patients with endometrioid histology and single site of bone metastasis experienced improved survival (p = 0.04 and p = 0.05, respectively). Eight patients had immunohistochemistry or molecular tumor profiles available for review. Seven of these patients (87.5%) were found to have microsatellite instability (MSI). The most common mutation was hypermethylation of MLH-1 (43%). To our knowledge, this is the first report demonstrating a correlation between MSI and metastasis to bone. The identification of BM in EC is uncommon, but will alter treatment strategies and dramatically impact prognosis. Molecular tumor profiling should be performed to identify targeted therapy options and optimize adjuvant treatment strategies.

RESUMO

INTRODUCTION: Thrombocytosis is present in a wide range of malignancies, with a reported incidence of 10% to 57%. Several reports have documented thrombocytosis at the time of diagnosis as a poor prognostic indicator. Our study is the first report evaluating the role of preoperative thrombocytosis and its association with survival in a predominantly African American and Caribbean American urban population. MATERIALS AND METHODS: We retrospectively reviewed the charts of 99 consecutive patients treated for endometrial carcinoma at SUNY Downstate Medical Center. Seventy-seven patients were deemed eligible for the study, and the following clinicopathologic characteristics were recorded from their medical records: age, stage, grade, histological subtype, presence of lymphovascular space invasion, depth of myometrial invasion, intrauterine tumor volume, preoperative prothrombin time, activated partial thromboplastin time, platelet count, progression-free survival (PFS), and overall survival (OS). The data were analyzed using Spearman and Pearson correlations, Student t test, chi(2) test, and Fisher exact test. Survival analysis was performed using Kaplan-Meier tables, log-rank test, and Cox proportional hazard model. The 2-tailed value of P < 0.05 was considered significant. RESULTS: Fourteen (18.2%) of 77 patients exhibited thrombocytosis (platelet count, >400 x 10(9)/L). Patients with advanced disease (stages III-IV) had a significantly higher mean preoperative platelet count (359 +/- 23.8 x 10(9)/L) in comparison with patients with localized disease (stages I-II, 283 +/- 14.3 x 10(9)/L, P = 0.005). The median PFS among patients with stages III and IV without preoperative thrombocytosis was 15.0 +/- 4.8 months (n = 21) and with thrombocytosis was 3.0 +/- 1.4 months (n = 8, P = 0.032). The median OS in patients without thrombocytosis was 24.0 +/- 4.5 months (n = 21) and in patients with thrombocytosis was 7.0 +/- 3.8 months (n = 8, P = 0.015). Multivariate analysis was performed using log-rank test and Cox proportional hazard model. The only variables that retained independent prognostic significance were stage (hazards ratio, 3.268; P = 0.040) and preoperative thrombocytosis (hazards ratio, 1.714 per 100 platelets; P = 0.030). Among patients with localized disease, preoperative thrombocytosis was not associated with worsened OS or PFS. CONCLUSIONS: Our data indicate that preoperative thrombocytosis among high-risk inner-city patients with stages III to IV endometrial cancer is an independent prognostic indicator. This is the first such report in a predominantly African American and Caribbean American population. Further research is needed to elucidate the mechanisms of thrombocytosis in malignancy. Association of thrombocytosis and aggressive tumor behavior warrants investigation of antiplatelet therapy and its effect on outcome.

RESUMO

OBJECTIVES: Paclitaxel is widely used in the treatment of gynecologic malignancies. It targets tumor cells in the M phase of the cell cycle. Cells in other phases survive the insult and repopulate the tumor. PNC-27 is a peptide synthesized of amino acids of the p53-MDM-2 binding domain. It kills various cancer cell lines in a dose-dependent manner. The goal of this study is to assess ovarian cancer cells' sensitivity to PNC-27 after surviving exposure to paclitaxel and to investigate the potential for synergy between PNC-27 and paclitaxel in the treatment of ovarian cancer. METHODS: The impact of exposure to paclitaxel on the surface expression of MDM-2 was assessed with the use of flow cytometry. For measurement of cytotoxicity in vitro, ID8 cells were exposed to paclitaxel for 12 hours in various concentrations. At 12 hours, the drug containing media was removed and the cells were cultured in media containing various concentrations of PNC-27 for 24 hours. Viability was assessed with the use of an MTT assay. Survival fractions were plotted against drug concentrations and the data were fit to logistic dose-response curves. Isoeffective combinations were used to create isobolograms. The combined treatment with weekly paclitaxel and PNC-27 was tested in an intraperitoneal mouse model of ovarian cancer (ID8). RESULTS: Exposure to paclitaxel rendered incomplete time-dependent killing, while PNC-27 mediated comprehensive, dose-dependent killing of ID8 cells. The cytotoxic effect of PNC-27 was dependent on its binding to MDM-2. Blocking MDM-2 inhibited the killing by PNC-27. ID8 cells surviving paclitaxel demonstrated increased expression of MDM-2 and increased susceptibility to PNC-27. Isobologram for dose combinations that were isoeffective indicates synergistic effect between the 2 agents (Combination index <1). In an in vivo model of ovarian cancer (ID8), the addition of PNC-27 to weekly paclitaxel administration significantly reduces tumor growth. CONCLUSIONS: These data demonstrate synergism between PNC-27 and paclitaxel. PNC-27 could target cells surviving paclitaxel and improve its antitumor effect.

RESUMO

OBJECTIVE: Despite an 80% response rate to chemotherapy, epithelial ovarian cancer has the highest case fatality rate of all gynecologic malignancies. Several studies have shown the efficiency of anticancer peptides PNC-27 and PNC-28 in killing a variety of cancer cells selectively in vitro and in vivo. The purpose of this study was to evaluate the efficacy of PNC-27 against human primary epithelial ovarian cancer. METHODS: We established primary cultures of freshly isolated epithelial ovarian cancer cells from patients with newly diagnosed ovarian cystadenocarcinomas. Two cell lines were obtained, one from mucinous cystadenocarcinoma, and the other from high-grade papillary serous carcinoma. The cancerous properties of these cells were characterized in vitro morphologically, by their growth requirements and serum independence. Treatment effects with PNC-27 were followed qualitatively by light microscopy, and quantitatively by measuring inhibition of cell growth using the MTT cell proliferation assay and direct cytotoxicity by measuring lactate dehydrogenase (LDH). RESULTS: PNC-27 inhibits in a dose-dependent manner the growth of and is cytotoxic to human primary cancer cells that had been freshly isolated from two ovarian epithelial cancers. The results further show that the control peptide PNC-29 has no effect on the primary cancer cells. Our results also show that PNC-27 is cytotoxic to cells from long-established and chemotherapy-resistant human ovarian cancer cell lines. CONCLUSION: These findings show, for the first time, the efficacy of PNC-27 on freshly isolated, primary human cancer cells. Our results indicate the potential of PNC-27 peptide as an efficient alternative treatment of previously untreated ovarian cancer as well as for ovarian cancers that have become resistant to present chemotherapies.

RESUMO

BACKGROUND AND OBJECTIVES: Our aim was to determine whether the use of routine cystoscopy increases lower urinary tract injury detection (bladder and/or ureter) after robotic surgery performed by gynecologic oncologists. METHODS: A retrospective chart review of patients who presented for robotic hysterectomy from 2009-2012 was performed at 2 separate academic medical centers, one that performed routine cystoscopy and one that did not. Statistical analysis was performed with t tests and χ2 tests. RESULTS: We identified 140 cases without cystoscopy and 109 cases with routine cystoscopy. There were no intraoperative or postoperative urinary injuries detected in either group. There were no significant differences in age and body mass index. In the non-cystoscopy group, a larger specimen size (P<.001), less blood loss (P=.013), and a longer mean operative time were observed (P<.0001). In the routine cystoscopy group, more lymphadenectomies were performed with hysterectomy (P=.007) and more patients underwent hysterectomy for ovarian cancer (P=.0192). There were no differences in surgical indications or secondary procedures including bilateral salpingo-oophorectomy, radical hysterectomy, ureterolysis, and pelvic organ prolapse-related procedures. The minimum follow-up period was 30 days in both groups. CONCLUSION: Routine use of cystoscopy did not appear to affect the detection rate of intraoperative lower urinary tract injury during robotic gynecologic surgery because this rate was zero in both groups. However, cystoscopy is relatively simple to perform and can be efficiently incorporated into robotic surgery to avoid the severe morbidity and possible litigation surrounding a urinary tract injury.

RESUMO

A cervical pregnancy is an uncommon ectopic pregnancy that accounts for less than 1% of such gestations. This condition is associated with an extremely high risk of massive hemorrhage and previously often required hysterectomy. The current diagnostic modality of this potentially life-threatening condition is transvaginal sonography, supported at times by magnetic resonance imaging. The definitive diagnostic imaging feature of a cervical pregnancy is the location of a gestational sac in the cervix in the presence of a closed internal uterine cervical os. We report the 3-dimensional transvaginal sonographic findings of a cervical pregnancy at 6 weeks' gestation.

RESUMO

Abdominal pregnancy is a rare condition in which the fetus and placenta are located within the peritoneal cavity. Sonographic findings include visualization of the fetus separate from the uterus, failure to visualize the uterine wall between the fetus and urinary bladder, close approximation of fetal parts to the maternal abdominal wall, eccentric position or abnormal fetal attitude, and visualization of extrauterine placental tissue. We present an unusual case in which mid-trimester transabdominal color Doppler sonographic findings depicted unusual maternal vasculature in the placental periphery leading to the diagnosis of abdominal pregnancy. Postpartum maternal angiography confirmed these vessels as abnormal maternal arterial perfusion of the extrauterine placenta emanating from the uterine arteries and inferior epigastric arteries. Systematic review of the literature confirms that this is the first report of such sonographic manifestations of an abdominal pregnancy.

RESUMO

OBJECTIVE: Coenzyme Q10 is an antioxidant that may have a therapeutic role in cervical cancer. STUDY DESIGN: We investigated the cellular and molecular effects of 30 micromol/L Coenzyme Q10 in HeLa cells. Cell growth assays, fluorescence-activated cell sorting analyses, and Oil Red O staining were performed. Microarray experiments were performed in duplicate and analyzed on the basis of 2-fold changes in levels of gene expression. RESULTS: Coenzyme Q10 inhibited cell growth and led to apoptosis. Microarray analysis showed that 264 sequences were altered over time, with enrichment in lipid-related genes. Enhanced lipid accumulation was confirmed with Oil Red O staining. CONCLUSION: A lipid response to Coenzyme Q10 may affect mechanisms of growth inhibition in HeLa cells.
