Improved survival with combination chemotherapy and external beam radiation therapy in uterine carcinosarcoma

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.

Optimal cytoreduction followed by chemoradiation in stage IVB uterine serous carcinoma

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.

Evaluation of the incidence and clinical significance of WT-1 expression in uterine serous carcinoma

Background

Wilms tumor gene 1 (WT1) expression is a hallmark of ovarian serous carcinoma and considered to be diagnostic marker of these tumors, differentiating them from uterine serous carcinoma (USC), historically thought to rarely express WT1. However, more recent data indicates a significant percentage of USC may express WT1. The clinical implications of WT1 positivity in USC remain unclear.

Methods

A multicenter retrospective analysis of patients with USC was conducted from 2000 to 2019. Inclusion criteria were patients who had undergone comprehensive surgical staging/tumor debulking with archival tissue available for WT1 assessment via immunohistochemistry (IHC). Chemosensitive patients were defined as those recurring >6 months from last platinum-based chemotherapy. 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

WT1 status was evaluated in 61 patients with USC. 13 (21.3%) were positive for WT1 by IHC. Stage distribution included 32% stage I, 5% stage II, 25% stage III and 38% stage IV. There was no difference in the stage (p = 0.158), race (p = 0.227) or distribution of recurrence sites (p = 0.581) between WT1 positive and WT1 negative tumors. The majority of patients were chemosensitive (63%). Chemosensitivity was significantly improved in WT1 positive (92.3%) vs. WT1 negative tumors (55.8%) (p = 0.016). We observed a trend towards improved PFS among WT1 positive tumors (21 vs. 16-months, respectively) (p = 0.544). On MVA, stage (p < 0.001) and chemosensitivity (p < 0.001) were independent predictors of PFS.

Conclusions

WT1 positivity is observed in over 20% of USC. WT1 expression is associated with improved chemosensitivity which may contribute to improvements in PFS.

COVID-19 outcomes of patients with gynecologic cancer in New York City: An updated analysis from the initial surge of the pandemic

Background

Despite significant increase in COVID-19 publications, characterization of COVID-19 infection in patients with gynecologic cancer remains limited. Here we present an update of COVID-19 outcomes among people with gynecologic cancer in New York City (NYC) during the initial surge of severe acute respiratory syndrome coronavirus 2 (coronavirus disease 2019 [COVID-19]).

Methods

Data were abstracted from gynecologic oncology patients with COVID-19 infection among 8 NYC area hospital systems between March and June 2020. Multivariable logistic regression was utilized to estimate associations between factors and COVID-19 related hospitalization and mortality.

Results

Of 193 patients with gynecologic cancer and COVID-19, the median age at diagnosis was 65.0 years (interquartile range (IQR), 53.0–73.0 years). One hundred six of the 193 patients (54.9%) required hospitalization; among the hospitalized patients, 13 (12.3%) required invasive mechanical ventilation, 39 (36.8%) required ICU admission. Half of the cohort (49.2%) had not received anti-cancer treatment prior to COVID-19 diagnosis. No patients requiring mechanical ventilation survived. Thirty-four of 193 (17.6%) patients died of COVID-19 complications. In multivariable analysis, hospitalization was associated with an age ≥ 65 years (odds ratio [OR] 2.12, 95% confidence interval [CI] 1.11, 4.07), Black race (OR 2.53, CI 1.24, 5.32), performance status ≥2 (OR 3.67, CI 1.25, 13.55) and ≥ 3 comorbidities (OR 2.00, CI 1.05, 3.84). Only former or current history of smoking (OR 2.75, CI 1.21, 6.22) was associated with death due to COVID-19 in multivariable analysis. Administration of cytotoxic chemotherapy within 90 days of COVID-19 diagnosis was not predictive of COVID-19 hospitalization (OR 0.83, CI 0.41, 1.68) or mortality (OR 1.56, CI 0.67, 3.53).

Conclusions

The case fatality rate among patients with gynecologic malignancy with COVID-19 infection was 17.6%. Cancer-directed therapy was not associated with an increased risk of mortality related to COVID-19 infection.

Evaluation of the optimal sequence of adjuvant chemotherapy and radiation therapy in the treatment of advanced endometrial cancer

OBJECTIVE

The optimal sequence of adjuvant chemoradiation in the treatment of advanced endometrial carcinoma (EC) remains unclear. We sought to evaluate the outcomes of patients treated with chemoradiation in sandwich fashion (chemotherapy-radiotherapy-chemotherapy; CRC), versus those treated sequentially (chemotherapy-radiotherapy; CR) (radiotherapy-chemotherapy; RC), to determine if there is a survival advantaged associated with a particular treatment sequence.

METHODS

A multicenter retrospective analysis of patients with stage III and IV EC from 2000-2018 was conducted. Inclusion criteria were patients who had undergone comprehensive surgical staging/tumor debulking; followed by adjuvant chemoradiation. Differences in the frequencies of adverse events were evaluated using Pearson's χ² test. Progression free survival (PFS) and overall survival (OS) rates were calculated using Kaplan-Meier estimates.

RESULTS

Final analysis included 152 patients; 36.8% (n=56) CRC, 28.9% (n=44) CR, and 34.2% (n=52) RC. Histology included 44.0% endometrioid, 47.5% serous and 8.5% clear cell tumors. There was no difference in the frequency of histology (p=0.973), stage (p=0.143), cytoreduction status (p=0.932), or treatment delays (p=0.571) between adjuvant therapy sequences. The most frequent location of disease recurrence was abdomen. The median PFS favored CRC versus CR or RC (36-months vs. 22-months and 24-months, respectively) (p=0.038), as did the median OS (48-months vs. 28-months and 34-months, respectively) (p=0.003). CRC demonstrated superiority over CR and RC sequencing in terms 3-year PFS (55% vs. 34% and 37%, respectively) and 3-year OS (71% vs. 50% and 52%, respectively).

CONCLUSIONS

Adjuvant chemoradiation delivered in CRC sequence was associated with improvements in both PFS and OS compared to alternant therapy sequencing.

Racial disparities in patients with coronavirus disease 2019 infection and gynecologic malignancy

BACKGROUND

Mounting evidence suggests disproportionate coronavirus disease 2019 (COVID-19) hospitalizations and deaths because of racial disparities. The association of race in a cohort of gynecologic oncology patients with severe acute respiratory syndrome-coronavirus 2 infection is unknown.

METHODS

Data were abstracted from gynecologic oncology patients with COVID-19 infection among 8 New York City area hospital systems. A multivariable mixed-effects logistic regression model accounting for county clustering was used to analyze COVID-19-related hospitalization and mortality.

RESULTS

Of 193 patients who had gynecologic cancer and COVID-19, 67 (34.7%) were Black, and 126 (65.3%) were non-Black. Black patients were more likely to require hospitalization compared with non-Black patients (71.6% [48 of 67] vs 46.0% [58 of 126]; P = .001). Of 34 (17.6%) patients who died from COVID-19, 14 (41.2%) were Black. Among those who were hospitalized, compared with non-Black patients, Black patients were more likely to: have ≥3 comorbidities (81.1% [30 of 37] vs 59.2% [29 of 49]; P = .05), to reside in Brooklyn (81.0% [17 of 21] vs 44.4% [12 of 27]; P = .02), to live with family (69.4% [25 of 36] vs 41.6% [37 of 89]; P = .009), and to have public insurance (79.6% [39 of 49] vs 53.4% [39 of 73]; P = .006). In multivariable analysis, among patients aged <65 years, Black patients were more likely to require hospitalization compared with non-Black patients (odds ratio, 4.87; 95% CI, 1.82-12.99; P = .002).

CONCLUSIONS

Although Black patients represented only one-third of patients with gynecologic cancer, they accounted for disproportionate rates of hospitalization (>45%) and death (>40%) because of COVID-19 infection; younger Black patients had a nearly 5-fold greater risk of hospitalization. Efforts to understand and improve these disparities in COVID-19 outcomes among Black patients are critical.

Inflammatory markers in gynecologic oncology patients hospitalized with COVID-19 infection

Objective

Elevated inflammatory markers are predictive of COVID-19 infection severity and mortality. It is unclear if these markers are associated with severe infection in patients with cancer due to underlying tumor related inflammation. We sought to further understand the inflammatory response related to COVID-19 infection in patients with gynecologic cancer.

Methods

Patients with a history of gynecologic cancer hospitalized for COVID-19 infection with available laboratory data were identified. Admission laboratory values and clinical outcomes were abstracted from electronic medical records. Severe infection was defined as infection requiring ICU admission, mechanical ventilation, or resulting in death.

Results

86 patients with gynecologic cancer were hospitalized with COVID-19 infection with a median age of 68.5 years (interquartile range (IQR), 59.0–74.8). Of the 86 patients, 29 (33.7%) patients required ICU admission and 25 (29.1%) patients died of COVID-19 complications. Fifty (58.1%) patients had active cancer and 36 (41.9%) were in remission. Patients with severe infection had significantly higher ferritin (median 1163.0 vs 624.0 ng/mL, p < 0.01), procalcitonin (median 0.8 vs 0.2 ng/mL, p < 0.01), and C-reactive protein (median 142.0 vs 62.3 mg/L, p = 0.02) levels compared to those with moderate infection. White blood cell count, lactate, and creatinine were also associated with severe infection. D-dimer levels were not significantly associated with severe infection (p = 0.20).

Conclusions

The inflammatory markers ferritin, procalcitonin, and CRP were associated with COVID-19 severity in gynecologic cancer patients and may be used as prognostic markers at the time of admission.

COVID-19 outcomes of patients with gynecologic cancer in New York City

BACKGROUND

New York City (NYC) is the epicenter of severe acute respiratory syndrome coronavirus 2 (coronavirus disease 2019 [COVID-19]) in the United States. Clinical characteristics and outcomes of vulnerable populations, such as those with gynecologic cancer who develop COVID-19 infections, is limited.

METHODS

Patients from 6 NYC-area hospital systems with known gynecologic cancer and a COVID-19 diagnosis were identified. Demographic and clinical outcome data were abstracted through a review of electronic medical records.

RESULTS

Records for 121 patients with gynecologic cancer and COVID-19 were abstracted; the median age at the COVID-19 diagnosis was 64.0 years (interquartile range, 51.0-73.0 years). Sixty-six of the 121 patients (54.5%) required hospitalization; among the hospitalized patients, 45 (68.2%) required respiratory intervention, 20 (30.3%) were admitted to the intensive care unit, and 9 (13.6%) underwent invasive mechanical ventilation. Seventeen patients (14.0%) died of COVID-19 complications. No patient requiring mechanical ventilation survived. On multivariable analysis, hospitalization was associated with an age ≥64 years (risk ratio [RR], 1.73; 95% confidence interval [CI], 1.18-2.51), African American race (RR, 1.56; 95% CI, 1.13-2.15), and 3 or more comorbidities (RR, 1.43; 95% CI, 1.03-1.98). Only recent immunotherapy use (RR, 3.49; 95% CI, 1.08-11.27) was associated with death due to COVID-19 on multivariable analysis; chemotherapy treatment and recent major surgery were not predictive of COVID-19 severity or mortality.

CONCLUSIONS

The case fatality rate among gynecologic oncology patients with a COVID-19 infection is 14.0%. Recent immunotherapy use is associated with an increased risk of mortality related to COVID-19 infection.

LAY SUMMARY

The case fatality rate among gynecologic oncology patients with a coronavirus disease 2019 (COVID-19) infection is 14.0%; there is no association between cytotoxic chemotherapy and cancer-directed surgery and COVID-19 severity or death. As such, patients can be counseled regarding the safety of continued anticancer treatments during the pandemic. This is important because the ability to continue cancer therapies for cancer control and cure is critical.

Cutaneous metastasis of PD-L1 positive ovarian carcinoma

•

Ovarian cancer (OC) metastasizes cutaneous in up to 6% of cases.

•

Cutaneous metastasis to the vulva is rare; with only one prior report in the literature.

•

Resection of cutaneous metastasis offers symptom relief as well as a potential survival benefit.

•

Molecular tumor profiling should be employed to expand therapy options.

Multimodality adjuvant therapy and survival outcomes in stage I–IV uterine carcinosarcoma

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.

A clinicopathologic study of endometrial cancer metastatic to bone: Identification of microsatellite instability improves treatment strategies

•

Metastasis of endometrial cancer (EC) to bone is rare, occurring in <1.0% of cases.

•

The most common sites of bone metastasis in EC are the spine and hip.

•

Diagnosis of bone metastasis is associated with widely metastatic disease and poor prognosis.

•

The median overall survival following a diagnosis of bone metastasis was 11 months in our series.

•

87.5% of patients with bone metastasis were found to have microsatellite instability.

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.

Surgical Management of Underlying Biliary Disease in Refractory Hyperemesis Gravidarum

Hyperemesis gravidarum (HEG) is the most common cause of hospitalization during the first half of pregnancy. It affects approximately 0.3-3% of all pregnancies [1]. There is no one accepted definition or diagnostic criteria for HEG. The most commonly cited criteria include persistent vomiting not related to other causes, measure of acute starvation (most commonly ketonuria), and weight loss; most often loss of at least 5% of pre-pregnancy body weight [2]. Symptoms typically begin in the late first trimester and are rarely associated with abdominal pain. HEG is managed a stepwise fashion by adding pharmacotherapy sequentially until symptom resolution [3, 4]. Patients who present with classic signs and symptoms of HEG but are non-responsive to all levels of therapy present a therapeutic challenge. In these cases, the search for other causes of nausea and vomiting should be undertaken. In the current report, we review 10 cases of refractory HEG. Eight patients were incidentally diagnosed with biliary disease by abdominal ultrasound (US) during workup for refractory symptoms. These patients underwent surgical consultation and were subsequently offered laparoscopic cholecystectomy. Here, we review the pregnancy courses from initial presentation until delivery to explore the incidence of underlying biliary disease and role of cholecystectomy in refractory HEG.

Breast metastases: A rare manifestation of advanced uterine serous carcinoma

•

Metastasis to the breast is a rare, accounting for <1.0% of all breast tumors.

•

Over 50% of patient with USC will recur despite multimodality treatment.

•

The majority of USC recur locally within the pelvis or abdominal cavity.

•

Hematogenous metastasis to the breast has not been reported in USC.

•

A new breast mass in a patient with USC is more likely to primary breast cancer.

Metastasis of non-mammary tumors to the breast are uncommon, representing <1% of all breast tumors. Breast metastasis are associated with advanced disease and poor prognosis regardless of the origin of the primary tumor. Uterine cancer metastasis to the breast is an extremely rare finding and has not been reported in the case of serous histology. Here, we review two cases of uterine serous carcinoma metastatic to the breast. Both patients presented with breast-specific complaints including pain and palpable mass and were found to have widely metastatic disease. Tissue biopsy and immunohistochemistry consistent with primary uterine serous carcinoma confirmed the diagnosis of metastasis in both cases. Our findings suggest hematogenous metastasis to the breast is a late phenomenon in the course of endometrial carcinoma and associated with the development of disease at multiple sites. This emphasizes the importance of complete evaluation in patients presenting with breast complaints and known history of malignancy, as this may be the only presenting symptoms in patients with widely metastatic disease.
