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.

Pancreatic ductal adenocarcinoma (PDAC) is a highly metastatic disease. Tumors are poorly immunogenic and immunosuppressive, preventing T cell activation in the tumor microenvironment. Here, we present a microbial-based immunotherapeutic treatment for selective delivery of an immunogenic tetanus toxoid protein (TT 856-1313 ) into PDAC tumor cells by attenuated Listeria monocytogenes . This treatment reactivated preexisting TT-specific memory T cells to kill infected tumor cells in mice. Treatment of KrasG12D,p53R172H, Pdx1-Cre (KPC) mice with Listeria -TT resulted in TT accumulation inside tumor cells, attraction of TT-specific memory CD4 T cells to the tumor microenvironment, and production of perforin and granzyme B in tumors. Low doses of gemcitabine (GEM) increased immune effects of Listeria -TT, turning immunologically cold into hot tumors in mice. In vivo depletion of T cells from Listeria -TT + GEM–treated mice demonstrated a CD4 T cell–mediated reduction in tumor burden. CD4 T cells from TT-vaccinated mice were able to kill TT-expressing Panc-02 tumor cells in vitro. In addition, peritumoral lymph node–like structures were observed in close contact with pancreatic tumors in KPC mice treated with Listeria -TT or Listeria -TT + GEM. These structures displayed CD4 and CD8 T cells producing perforin and granzyme B. Whereas CD4 T cells efficiently infiltrated the KPC tumors, CD8 T cells did not. Listeria -TT + GEM treatment of KPC mice with advanced PDAC reduced tumor burden by 80% and metastases by 87% after treatment and increased survival by 40% compared to nontreated mice. These results suggest that Listeria -delivered recall antigens could be an alternative to neoantigen-mediated cancer immunotherapy.

Care of women with endometrial cancer has been concentrated to a smaller number of surgeons and hospitals. The association between surgeon and hospital volume for endometrial cancer is complex with an increased risk of adverse outcomes among medium-volume hospitals and surgeons but the lowest complication rates for the highest volume surgeons and centers.
