RESUMO
OBJECTIVE(S): To evaluate whether extended dosing of antibiotics (ABX) after cytoreductive surgery (CRS) with large bowel resection for advanced ovarian cancer is associated with reduced incidence of surgical site infection (SSI) compared to standard intra-operative dosing and evaluate predictors of SSI. METHODS: A retrospective single-institution cohort study was performed in patients with stage III/IV ovarian cancer who underwent CRS from 2009 to 2017. Patients were divided into two cohorts: 1) standard intra-operative dosing ABX and 2) extended post-operative ABX. All ABX dosing was at the surgeon's discretion. The impact of antibiotic duration on SSI and other postoperative outcomes was assessed using univariate and multivariable Cox regression models. RESULTS: In total, 277 patients underwent cytoreductive surgery (CRS) with large bowel resection between 2009 and 2017. Forty-nine percent (n = 137) received standard intra-operative ABX and 50.5% (n = 140) received extended post-operative ABX. Rectosigmoid resection was the most common large bowel resection in the standard ABX (89.9%, n = 124) and extended ABX groups (90.0%, n = 126), respectively. No significant differences existed between age, BMI, hereditary predisposition, or medical comorbidities (p > 0.05). No difference was appreciated in the development of superficial incisional SSI between the standard ABX and extended ABX cohorts (10.9% vs. 12.9%, p = 0.62). Of patients who underwent a transverse colectomy, a larger percentage of patients developed a superficial SSI versus no SSI (21% vs. 6%, p = 0.004). CONCLUSION(S): In this retrospective study of patients with advanced ovarian cancer undergoing CRS with LBR, extended post-operative ABX was not associated with reduced SSI, and prolonged administration of antibiotics should be avoided unless clinically indicated.

BACKGROUND: We sought to create a laparoscopic-based model to predict the ability to perform a minimally invasive (MIS) cytoreductive surgery in advanced epithelial ovarian cancer patients who have received neoadjuvant chemotherapy (NACT). METHODS: Fifty women were enrolled in a multi-institutional prospective pilot study (NCT03378128). Each patient underwent laparoscopic evaluation of 43 abdominopelvic sites followed by surgeon dictated surgical approach, either continue MIS or laparotomically. However, if the procedure continued MIS, the placement of a hand-assist port for manual palpation was mandated to emulate a laparotomic approach and all 43 sites were re-evaluated. Sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy were calculated for each site to predict MIS resectability. Each parameter was assigned a numeric value based on the strength of statistical association and a total predictive index score (PIV) was assigned for each patient. Receiver operating characteristic curve analysis was used to assess the ability of the model to predict the MIS approach. RESULTS: Twenty-seven patients (61%) underwent MIS surgery. The following abdominopelvic sites were selected for inclusion in the model: gastrosplenic ligament, rectum, left mesocolon, transverse colon, right colon, cecum, appendix, liver capsule, intrahepatic fossa/gallbladder, ileum/jejunum. Using the PIV, a ROC was generated with an AUC = 0.695. In the final model, a PIV <2 identified patients able to undergo an optimal MIS cytoreductive surgery with an accuracy of 68.2%. The specificity, or the ability to identify patients who would not be able to undergo an optimal MIS interval cytoreductive surgery, was 66.7%. CONCLUSION: This predictive index model may help to guide future inclusion criteria in randomized studies evaluating the MIS approach in advanced epithelial ovarian cancer.

OBJECTIVE: To evaluate the safety, tolerability, and efficacy of topical artesunate ointment for treatment of biopsy-confirmed Human papillomavirus (HPV)-associated Vulvar intraepithelial neoplasia (VIN) 2/3. METHODS: Participants were enrolled on a prospective, IRB-approved, dose-escalation phase I trial testing either 1, 2 or 3 treatment cycles (5 days), every other week, as applicable. Clinical assessments were completed prior to each dose cycle and included exam and review of adverse event (AE) diary cards. HPV testing and colposcopy was completed at 15 and 28 weeks. AEs were assessed according to CTCAE 4.0 criteria. Complete responders (CR) underwent biopsy of the treated site at the 28-weeks while partial (PR) and non (NR)-responders underwent surgical resection or biopsy and ablation. RESULTS: Fifteen patients consented to and began treatment. Per-protocol assessments were completed in 100% at 15- and 80% at 28-weeks. All patients completed prescribed cycles with no grade 3 or 4 AEs. Vulvovaginal burning/ was the most common AE occurring in 93.3%. AEs were grade 2 in 23.7% and included vulvovaginal pruritus (n = 3), swelling (n = 3) and candidiasis (n = 2). The highest ORR was in the 3-cycle group (88.9% with 55.6% CR). HPV-16 was detected either alone (46.7%) or with other subtypes (33.3%) in 80% of lesions and 5 of 8 (62.5%) with CR had complete viral clearance. CONCLUSIONS: Topical artesunate for treatment of high-grade VIN shows high tolerability, low toxicity and evidence for clinical response in this initial small series. The safety and observed responses support further study in a Phase II trial.

OBJECTIVE: Gynecologic cancers are traditionally managed according to their presumed site of origin, without regard to the underlying histologic subtype. Clear cell histology is associated with chemotherapy refractoriness and poor survival. Mutations in SWI/SNF chromatin remodeling complex member ARID1A, which encodes for BAF250a protein, are common in clear cell and endometriosis-associated endometrioid carcinomas. High-throughput cell-based drug screening predicted activity of dasatinib, a tyrosine kinase inhibitor, in ARID1A-mutant clear cell carcinoma. METHODS: We conducted a phase 2 clinical trial of dasatinib 140 mg once daily by mouth in patients with recurrent or persistent ovarian and endometrial clear cell carcinoma. Patients with measurable disease were enrolled and then assigned to biomarker-defined populations based on BAF250a immunohistochemistry. The translational endpoints included broad next-generation sequencing to assess concordance of protein expression and treatment outcomes. RESULTS: Twenty-eight patients, 15 of whom had tumors with retained BAF250a and 13 with loss of BAF250a were evaluable for treatment response and safety. The most common grade 3 adverse events were anemia, fatigue, dyspnea, hyponatremia, pleural effusion, and vomiting. One patient had a partial response, eight (28%) had stable disease, and 15 (53.6%) had disease progression. Twenty-three patients had next-generation sequencing results; 13 had a pathogenic ARID1A alteration. PIK3CA mutations were more prevalent in ARID1A-mutant tumors, while TP53 mutations were more prevalent in ARID1A wild-type tumors. CONCLUSIONS: Dasatinib was not an effective single-agent treatment for recurrent or persistent ovarian and endometrial clear cell carcinoma. Studies are urgently needed for this rare gynecologic subtype.

OBJECTIVE: To compare response rate, progression-free survival, overall survival, and toxicity of carboplatin and gemcitabine administered on day 1 and day 8 (day1&8) versus a modified day 1-only regimen in recurrent platinum-sensitive ovarian cancer. METHODS: A retrospective single-institution cohort study was performed in women with recurrent platinum-sensitive ovarian cancer between January 2009 and December 2020 treated with carboplatin and gemcitabine on a 21-day cycle. The impact of dosing schedule on response rate, progression-free survival, overall survival, and toxicities was assessed with univariate and multivariate models. RESULTS: Of 200 patients, 26% (n=52) completed day 1&8, 21.5% (n=43) started day 1&8 but dropped day 8, and 52.5% (n=105) received day 1-only. There were no differences in demographics. Median starting carboplatin and gemcitabine doses were area under curve (AUC) 5 and 600 mg/m2 for day 1-only versus AUC4 and 750 mg/m2 among day 1&8, respectively (p<0.001). A total of 43 patients (45.3%) dropped day 8 primarily due to neutropenia (51.2%) or thrombocytopenia (30.2%). The response rates were 69.3% for day 1&8-completed, 67.5% for day 1&8-dropped, and 67.6% for day 1-only (p=0.92). Median progression-free survival was 13.1, 12.1, and 12.4 months for day 1&8-completed, day 1&8-dropped, and day 1-only, respectively (p=0.29). Median overall survival was 28.2, 33.5, and 34.3 months for the above groups (p=0.42). The rate of grade 3/4 hematologic toxicity (48.9% vs 31.4%, p=0.002), dose reductions (58.9% vs 33.7%, p<0.001), blood transfusions (22.1% vs 10.5%, p=0.025), and treatment with pegfilgrastim (64.2% vs 51%, p=0.059) were higher among day 1&8 versus day 1-only, respectively. CONCLUSIONS: There was no difference in response rate, progression-free survival, or overall survival for day 1&8 versus day 1-only, regardless of whether day 8 was dropped. Day 1&8 was associated with greater hematologic toxicity. A modified day 1-only regimen may represent an alternative to day 1&8 and warrants prospective study.

BACKGROUND: Tension-free abdominal closure is a primary tenet of laparotomy. But this concept neglects the baseline tension of the abdominal wall. Ideally, abdominal closure should be tailored to restore native physiologic tension. We sought to quantify the tension needed to re-establish the linea alba in patients undergoing exploratory laparotomy. METHODS: Patients without ventral hernias undergoing laparotomy at a single institution were enrolled from December 2021 to September 2022. Patients who had undergone prior laparotomy were included. Exclusion criteria included prior incisional hernia repair, presence of an ostomy, large-volume ascites, and large intra-abdominal tumors. After laparotomy, a sterilizable tensiometer measured the quantitative tension needed to bring the fascial edge to the midline. Outcomes included the force needed to bring the fascial edge to the midline and the association of BMI, incision length, and prior lateral incisions on abdominal wall tension. RESULTS: This study included 86 patients, for a total of 172 measurements (right and left for each patient). Median patient BMI was 26.4 kg/m2 (IQR 22.9;31.5), and median incision length was 17.0 cm (IQR 14;20). Mean tension needed to bring the myofascial edge to the midline was 0.97 lbs. (SD 1.03). Mixed-effect multivariable regression modeling found that increasing BMI and greater incision length were associated with higher abdominal wall tension (coefficient 0.04, 95% CI [0.01,0.07]; p = 0.004, coefficient 0.04, 95% CI [0.01,0.07]; p = 0.006, respectively). CONCLUSION: In patients undergoing laparotomy, the tension needed to re-establish the linea alba is approximately 1.94 lbs. A quantitative understanding of baseline abdominal wall tension may help surgeons tailor abdominal closure in complex scenarios, including ventral hernia repairs and open or burst abdomens.

OBJECTIVE(S): To assess incidence and oncologic outcomes in women with advanced epithelial ovarian cancer (EOC) with inguinal lymph node metastasis (ILNM) at diagnosis. METHODS: An IRB-approved, retrospective single-institution cohort study was performed in women with stage III/IV EOC from 2009 to 2017. Patients with inguinal lymphadenopathy (defined as >1 cm in short axis) clinically or radiographically were identified. The impact of ILNM on progression-free survival (PFS) and overall survival (OS) were assessed. RESULTS: Of the 562 women with advanced EOC, 18 (3.2%) had ILNM at diagnosis, accounting for 25.7% of all patients with stage IVB disease (n = 70). Five patients (27.7%) had a known genetic predisposition for EOC, including BRCA1 (11.1%, n = 2), BRCA2 (11.1%, n = 2) and BRIP1 (5.6%, n = 1). The majority of patients underwent optimal primary cytoreductive surgery (CRS), including debulking of inguinal nodal metastasis (83.3%, n = 15), with 50% (n = 9) having no gross residual disease after surgery. There was no difference in PFS (19.9 vs. 19.9 vs. 17.2 months, p = 0.84) or OS (137.2 vs. 52.9 vs. 67.6 months, p = 0.29) in women with stage III/IV with ILNM, stage III/IV without ILNM, and stage IVB disease without ILNM, respectively. Progression-free survival was improved in women with ILNM who underwent an optimal resection to no macroscopic disease vs. non-optimal resection (27.4 vs. 14.3 months, p = 0.019). Median overall survival at the time of analysis did not reach statistical significance (137.2 vs. 57.3 months, p = 0.24). CONCLUSION(S): In this retrospective cohort study, 3.2% of women with advanced EOC presented with ILNM at diagnosis. Although ILNM did not portend worse clinical outcomes compared to all Stage III/IV and Stage IVB patients, respectively, resection to no gross residual disease was associated with improved PFS.

OBJECTIVE: To develop and validate a comprehensive overall survival (OS) risk-scoring model in women with endometrioid endometrial cancer (EC). METHODS: Patients with EC diagnosed from 2004 to 2013 were identified through the National Cancer Database (NCDB). Patients with known lymphovascular space invasion (LVSI) status who were treated surgically (with or without adjuvant therapy) were included. Cox proportional hazards analysis was used to identify prognostic factors for OS. This model was used to assign points based on hazard ratios for risk factors and a risk score was obtained. Recursive partitioning analysis (RPA) was used to categorize patients into risk groups. Results were internally validated in a cohort of patients from our institution (CCF cohort). Risk scores were calculated and assessed in a Cox regression model, and Harrell's c-index was calculated to assess model fit. RESULTS: Among 349,404 women with EEC during the study period, 42,107 fulfilled inclusion criteria. Factors associated with worse OS were age ≥ 60, African American race, Charlson-Deyo score 1 or 2+, higher grade, LVSI, tumor size ≥2 cm, and no lymphadenectomy performed. Six risk groups were identified (scores 0-30) and OS estimated for each risk group. Risk score per 1-point increase in HR were comparable between NCDB and CCF cohorts (HR 1.21 (1.20-1.22 p < 0.001 vs 1.18 (1.12-1.25), p < 0.001), and c-index 0.80 (0.79-0.81) vs. 0.77 (0.68-0.86). Similar analysis was done in stage IA and IB. Adjuvant therapy had a beneficial effect on survival in the majority of stage IB patients, but only one of the six risk groups in stage IA EC. CONCLUSIONS: We report a comprehensive validated OS risk-scoring model for patients with.

OBJECTIVE(S): To evaluate the incidence and associated risk factors for anastomotic failure following interval debulking surgery (IDS) with or without hyperthermic intraperitoneal chemotherapy (HIPEC) in women with advanced ovarian cancer. METHODS: We performed a retrospective cohort study in women with stage III/IV high-grade ovarian cancer treated with neoadjuvant chemotherapy followed by IDS with colorectal resection and HIPEC from 2017 to 2020. These patients were compared to a historical control cohort who underwent IDS with colorectal resection without HIPEC from 2009 to 2016. Data was collected for demographics, surgical variables, and perioperative outcomes. The univariate analysis compared progression-free survival and overall survival. RESULTS: 61 women were identified; 21 (34.4%) underwent IDS with HIPEC from 2017 to 2020, and 40 underwent IDS alone from 2009 to 2016. None of the patients who had IDS with HIPEC had protective ileostomy, compared to 10.0% of those who received had IDS alone (n = 4)(p = 0.29). The cumulative incidence of anastomotic leak rate was 8.2% (n = 5). There was no significant difference in anastomotic leak rate for women who underwent IDS with HIPEC (9.5%, n = 2) versus without HIPEC (7.5%, n = 3) (p = 0.99). While there was no difference in PFS (12.2 vs. 13.3 months, log-rank p = 0.31), OS (9.4 vs. 40.6 months, log-rank p = 0.013) was significantly decreased following postoperative anastomotic leak. CONCLUSIONS: In this retrospective series of women with advanced ovarian cancer, HIPEC was not associated with increased risk for anastomotic leak at the time of IDS with colorectal resection and reanastomosis. While further study is needed, HIPEC alone should not preclude colorectal resection or dictate practices for colonic diversion in IDS.

OBJECTIVE(S): To evaluate the impact of frailty on postoperative complications following cytoreductive surgery (CRS) with hyperthermic intra-peritoneal chemotherapy (HIPEC) in women with advanced or recurrent gynecologic cancer. METHODS: An IRB-approved single-institution prospective registry was queried for women who underwent CRS with HIPEC for advanced or recurrent gynecologic cancer from 1/1/2014-12/31/2020. Frailty was defined as a modified Frailty Index (mFI) score of ≥2. Logistic regression was used to assess the impact of mFI upon the rate of moderate or higher (≥ grade 2) Accordion postoperative complications. RESULTS: Of 141 women, 81.6% (n = 115) were non-frail with mFI of 0-1 and 18.4% (n = 26) were frail with mFI ≥2. The incidence of ≥ grade 2 complications was 21.2% (n = 14) for mFI = 0, 26.5% (n = 13) for mFI = 1, 64.7% (n = 11) for mFI = 2 and 100.0% (n = 9) for patients with mFI ≥3. The incidence of re-operation (1.7% vs. 11.5%, p = 0.044), ICU admission (13.2% vs. 34.6%, p = 0.018), acute kidney injury (6.3% vs. 30.8%, p = 0.001), and respiratory failure (0.9% vs. 19.2%, p < 0.001) were significantly lower amongst non-frail vs. frail women. On multivariable analysis, mFI ≥2 was associated with significantly increased ≥ grade 2 complications versus mFI of 0-1 (OR 9.4, 95% CI 3.3, 26.4, p < 0.001). Age (OR 1.04, 95% CI 1.00, 1.09, p = 0.07), surgical indication (recurrent vs. primary) (OR 0.71, 95% CI 0.30, 1.7, p = 0.44) and Surgical Complexity Score of Intermediate or High vs. Low (OR 1.5, 95% CI 0.67, 3.5, p = 0.31) were not associated with ≥grade 2 complications. CONCLUSIONS: Frailty, defined by the modified frailty index, is predictive of ≥grade 2 postoperative complications following CRS with HIPEC in women with gynecologic cancer. Frailty screening before CRS with HIPEC may assist patient selection and improve postoperative outcomes.

OBJECTIVE(S): To identify recurrence patterns and outcomes in women with advanced or recurrent epithelial ovarian cancer (EOC) after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: This is an IRB-approved single-institution cohort study of women who underwent CRS+HIPEC for advanced or recurrent EOC followed in a prospective registry from 1/12/2014-3/1/2020. Recurrence locations were defined as pelvic, upper abdominal (UA) and/or extra-peritoneal (EP). Univariate analysis assessed associations between recurrence location, progression-free survival (PFS), and overall survival (OS). RESULTS: In total, 92 women with EOC underwent interval (56.5%; n=52) or recurrent CRS+HIPEC (43.5%; n=40). For interval CRS+HIPEC, recurrence locations were pelvic in 50.0% (n=15), UA in 23.3% (n=7) and EP in 56.7% (n=17); 40.0% (n=12) were EP alone. Similarly, for recurrent CRS+HIPEC, recurrence locations were pelvic (22.5%, n=9), UA (5.0%, n=2) and EP (60.0%, n=24); 66.7% (n=20) were EP alone. For both interval and recurrent CRS+HIPEC, median PFS was 10.5 vs. 13.0 months for pelvic and UA vs. EP only recurrences (p=0.02). Similarly, median OS was 29.2 months for pelvic and UA and not reached for EP only (p=0.05). For interval CRS+HIPEC, there was no difference in median PFS (10.6 vs. 11.7 months, p=0.68) and OS (27.1 vs. 24.8 months, p=0.96) for pelvic and UA vs EP alone. However, for recurrent CRS+HIPEC, pelvic and UA sites of recurrence were associated with reduced PFS (10.0 vs. 18.1 months, p=0.03) and OS (33.6 months vs. not reached, p=0.02) vs. EP only. CONCLUSIONS: In women with advanced or recurrent EOC undergoing CRS+HIPEC, one-half of patients experience their first recurrence outside of the peritoneal cavity. Providers must be aware of the risk of EP failure in patients treated with CRS+HIPEC.

OBJECTIVES: To evaluate the incidence of intra-operative metabolic and electrolyte abnormalities and subsequent impact on peri-operative outcomes in women with gynecologic cancer undergoing cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS + HIPEC). METHODS: An IRB-approved single institution retrospective cohort study was performed in women with gynecologic cancer who underwent CRS + HIPEC. Patient demographics, intra-operative electrolyte and metabolic values and peri-operative outcomes were recorded. To assess the association of pH and lactate upon post-operative outcomes, patients were divided in four quartiles for both variables and univariate analysis was performed. RESULTS: 100 consecutive women who underwent CRS + HIPEC from 2017 to 2020 were identified. Intra-operative blood transfusion and pressor support were required in 40% and 86%, respectively. The rate of ICU admission was 17%. Longer operative time (7.0 vs. 5.3 h, p = 0.002), increased blood loss (400.0 vs. 200.0 mL, p = 0.02) and transfusion (70.6% vs. 34.1%, p = 0.005) were associated with ICU admission. Compared to patients in the highest quartile of pH, lower median pH, (7.211 vs. 7.349, p < 0.001) was associated with increased rates of ICU admission, prolonged intubation (36.0% vs. 0.0%, p < 0.05, respectively) and any post-operative complication (72.0% vs. 28.0%, p = 0.01). Similarly, need for prolonged intubation (40% vs. 0%, p = 0.04) and VTE (13.0% vs. 0%, p = 0.01) were increased in women with the highest quartile of lactate levels compared to the lowest (4.7 vs 1.9, p < 0.001). CONCLUSIONS: Intra-operative acidosis is associated with higher incidence of ICU admission and peri-operative complications following CRS + HIPEC in women with gynecologic cancer. These data support the importance of adequate intra-operative resuscitation and timely correction of hemodynamic and metabolic abnormalities.

OBJECTIVE: To determine peri-operative outcomes in women with advanced epithelial ovarian cancer (EOC) undergoing interval debulking surgery (IDS) with hyperthermic intraperitoneal chemotherapy (HIPEC) via minimally invasive interval debulking surgery (MIS) or laparotomy (LAP). METHODS: A single institution, retrospective cohort study was performed in women with EOC who underwent IDS with HIPEC from 2017 to 2019 via MIS or LAP. Peri-operative outcomes were compared using univariate analysis. RESULTS: In total, 50 eligible women were identified; ten (20.0%) underwent MIS + HIPEC and 40 (80.0%) LAP + HIPEC. The median age of patients in the MIS group was 71.1 vs. 64.2 years in LAP (p = 0.031). There was no significant difference in pre-operative complete radiographic response following NACT (p = 0.18). Notably, there was no difference in the rate of R0 resection (70.0% vs. 77.5%; p = 0.39). There was no significant difference in ICU admission, estimated blood loss, operative time, or use of vasopressors between the cohorts. Similarly, there was no difference in 30-day adverse events for MIS vs. LAP, but length of stay was decreased for those who underwent minimally invasive procedures (3 vs. 4 days, p = 0.016). Time to initiation of chemotherapy following surgery was not significantly different between groups (26.2 days vs 32.0 days, p = 0.090). With median follow-up of 15.1 months, there was no difference in recurrence free survival (median 15.0 vs 17.2 months log-rank, p = 0.30) for MIS vs. LAP. CONCLUSIONS: In this retrospective cohort study, we demonstrate that in women with advanced EOC, HIPEC with MIS at the time of IDS following NACT is feasible. Our institutional experience demonstrates similar rates of R0 cytoreduction, compared to LAP. An MIS approach should not prevent surgeons from utilizing HIPEC where indicated for management of advanced EOC.

To determine the effect of poly-adenosine ribose phosphatase inhibitors (PARPi) on the response to subsequent platinum-based chemotherapy (PBC) in patients with recurrent, platinum-sensitive BRCA-mutated epithelial ovarian, peritoneal, or fallopian cancer (BRCAm EOC). This is a retrospective, single-institution cohort study of patients with BRCAm EOC who received retreatment with PBC. The PFS of patients with BRCAm EOC to 2nd or 3rd PBC with and without a prior PARPi was determined. Additionally, we compared the PFS to subsequent PBC following a prior PARPi for BRCAm and non-BRCAm. One hundred and fifteen patients with BRCAm EOC received a 2nd PBC and 55 received a 3rd PBC. The median PFS was 2.3 and 2.4 times longer, respectively for patients who did not receive a PARPi, (2nd P = 0.005, 3rd P < 0.001). Among 20 PARPi exposed patients with BRCAm EOC the PFS to a 2nd or 3rd PBC was worse at 8.0 months vs. 19.1 months HR 4.01 [2.25,7.16], P < 0.001. Following PARPi exposure the PFS for patients with BRCAm EOC was similar for patients with platinum-free intervals of 6-12, 12-24 and >24 months. Following PARPi exposure the PFS was similar for patients with BRCAm EOC and non BRCAm EOC. Among patients with BRCAm EOC PARPi exposure significantly reduced PFS following 2nd and 3rd PBC. PARPi exposure nullifies established prognostic factors (i.e. platinum-free interval and BRCA mutational status) in platinum-sensitive recurrent ovarian cancer.

OBJECTIVE: To evaluate perioperative outcomes in elderly versus non-elderly women with advanced or recurrent epithelial ovarian cancer undergoing surgery with hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: A single-institution prospective registry was analyzed for women with ovarian cancer who underwent surgery with HIPEC from January 2014 to December 2020. Elderly age was defined as ≥65 years at surgery. Complications were defined according to the Accordion scale. Univariate and multivariable analysis was used to compare progression-free survival and overall survival. RESULTS: Of 127 women who underwent surgery with HIPEC, 33.1% (n=42) were ≥65 and 17.3% (n=22) were ≥70 years old. The median age for non-elderly and elderly patients were 55.7±8.3 versus 72.0±5.4 years, respectively (p<0.001). The majority of non-elderly versus elderly patients underwent HIPEC at the time of interval cytoreductive surgery following neoadjuvant chemotherapy (52.9% vs 73.8%, p=0.024). There were no differences in moderate (15.3% vs 26.2%) or severe postoperative complications (10.6% vs 11.9%, p=0.08), acute kidney injury (7.1% vs 16.7%, p=0.12), and length of stay (5.0 vs 5.0 days, p=0.56) for non-elderly versus elderly patients. With a median follow-up of 20 months (95% CI 9.1 to 32.7 months), there was no difference in progression-free survival (18.8 vs 15.7 months, p=0.75) or overall survival (61.6 months vs not estimable, p=0.72) for non-elderly versus elderly patients. Comparing patients 65-69 versus ≥70 years, progression-free survival (33.0 vs 12.5 months, p=0.002) was significantly improved in patients aged 65-69, without difference in overall survival (not estimable vs 36.0 months, p=0.91). On multivariable analysis, age ≥65 did not impact progression-free survival (p=0.74). CONCLUSIONS: In this prospective registry of women with ovarian cancer, perioperative morbidity is not increased for non-elderly versus elderly patients following surgery with HIPEC. While age should not exclude patients from surgery with HIPEC, additional research is needed regarding oncologic benefits in elderly women.

OBJECTIVE: To evaluate the efficacy and toxicity of extended duration pegylated liposomal doxorubicin (PLD) in women with recurrent epithelial ovarian carcinoma (rEOC). METHODS: Women with rEOC who received >7 cycles of PLD were retrospectively identified. Response was determined by RECIST 1.1. Progression free survival (PFS) and overall survival (OS) were calculated from PLD initiation. Toxicity was assessed by CTCAE v5.0. Kaplan Meier estimates and Cox proportional hazards were used to evaluate differences in time to recurrence or survival. RESULTS: 69 patients with rEOC received a median of 11.0 cycles (range, 7-115) at a median cumulative dose of 400 mg/m2 (range, 210-4600 mg/m2); 29.0% (n = 20) had platinum sensitive and 71.0% (n = 49) had platinum resistant disease. Of the observed grade ¾ toxicities (31.9%; n = 22), dermatologic were most frequent (n = 13; 18.8%). 41 women (59.4%) experienced clinical benefit; complete response in 17.4% (n = 12), partial response in 13.0% (n = 9) and stable disease in 29.0% (n = 20). Median PFS for all patients was 13.0 months (95% CI, 10.7, 15.2); there were no significant differences between platinum sensitive versus resistant disease (15.9 months vs. 12.3 months; HR 1.15, 95% CI, 0.66, 2.00; p = .61). With extended duration PLD, median OS was 40.2 months (95% CI 30.0, 49.0); no significant differences were noted for platinum sensitive versus resistant disease (44.7 months vs. 33.3 months; HR 1.85, 95% CI, 0.91, 3.78; p = .07). Four cases (5.8%) of oral squamous cell carcinoma occurred during treatment. CONCLUSIONS: Among women with both platinum sensitive and resistant rEOC who received >7 cycles of PLD, approximately one-half experienced sustained clinical benefit with acceptable toxicity. PLD may be considered for extended usage and maintenance in initially responding women with rEOC at least stable disease.

OBJECTIVE(S): To determine whether antibiotic treatment (ABX) during platinum chemotherapy (PC) for epithelial ovarian cancer (EOC) impacts progression-free survival (PFS) and overall survival (OS). STUDY DESIGN: Retrospective single institution cohort study in women with newly diagnosed stage III/IV EOC (n = 424) who underwent cytoreductive surgery (CRS) and PC from 2009 to 2015. ABX for >48 h, including ABX against gram-positive (anti-G + ABX) bacteria were recorded. The impact of ABX on PFS and OS was assessed using univariate and multivariable Cox regression models. RESULTS: Of 424 eligible women, 34.7% (n = 147) received ABX, with 11.3% (n = 48) treated with anti-G + ABX. ABX decreased PFS (17.4 vs. 23.1 months, HR 1.50, 95% CI 1.20-1.88, p < 0.001) and OS (45.6 vs. 62.4 months, HR 1.63, 95% CI 1.27-2.08, p < 0.001) compared to no ABX. Similarly, anti-G + ABX worsened PFS (16.5 vs. 23.1 months; HR 1.85, 95% CI 1.33-2.55) and OS (35.0 vs. 62.4 months; HR 2.12, 95% CI 1.50-3.0, p < 0.001). On multivariable analysis, all ABX and anti-G + ABX significantly worsened PFS (HR 1.31, 95% CI 1.04-1.65, p = 0.02), (HR 1.50, 95% CI 1.07-2.10, p = 0.02) and OS (HR 1.52, 95% CI 1.18-1.96, p = 0.001), (HR 1.83, 95% CI 1.27-2.62, p = 0.001) respectively. Increased Clavien Dindo score was associated with worsened PFS (1-2 - HR 1.52, 95% CI 1.14-2.03, p = 0.004; 3-4 - HR 1.86, 95% CI 1.27-2.72, p = 0.001) but not OS (1/2 - HR 1.35, 95% CI 0.97-1.88, p = 0.08; 3/4 - HR 1.53, 95% CI 1.00-2.34, p = 0.05); residual disease (p < 0.05) and neoadjuvant chemotherapy (p < 0.001) were associated with worse PFS and OS. CONCLUSION(S): In this retrospective cohort study of women with advanced EOC undergoing PC, ABX treatment was associated with decreased PFS and OS. Mechanistic studies are needed to investigate the negative impact of ABX upon PC response in EOC.

Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) may be used to treat peritoneal based malignancies, such as epithelial ovarian cancer (EOC). Despite results of clinical trials supporting an increasing indication for HIPEC in EOC, concerns have existed regarding morbidity and challenges with initiating HIPEC at an institutional level. The objective of this review is to describe evidence-based recommendations to guide implementation of a HIPEC program, following our experience at a high-volume tertiary care center. Establishing a HIPEC program requires building a multi-disciplinary team, including gynecologic oncologists, anesthesia, nursing, perfusionists and pharmacists. Team members require education regarding HIPEC protocols, toxic waste and spill management, and personal protective equipment (PPE). Required equipment includes chemotherapy certified PPE and a HIPEC pump which is connected to inflow and outflow catheters placed within the peritoneal cavity. During the procedure, 3-6 L of a hyperthermic perfusate, composed of a isotonic crystalloid vehicle and the chemotherapy of choice, is infused through the peritoneal cavity with goal temperature of 41-43 °C. Prior to HIPEC infusion, surgical teams must communicate with anesthesia and pharmacy. In patients receiving HIPEC with cisplatin, furosemide and mannitol should be administered one hour prior to chemotherapy to ensure adequate diuresis. Sodium thiosulfate may also be considered for renal protection (van Driel et al., n.d. [3]). We utilize a multi-agent pre-medication protocol prior to HIPEC infusion to reduce hypersensitivity reactions, renal toxicity and post-operative nausea and vomiting. Limited data exists to support the optimal regimen for HIPEC at the time of CRS in women with EOC. From our experience, we favor use of cisplatin 100 mg/m2 alone or in combination with paclitaxel 135-175 mg/m2 with 90 min of total perfusion time. Close attention to temperature and glycemic control is essential during the procedure, as electrolyte derangements including hyperglycemia, lactic acidosis and hypokalemia may occur. Continuous patient monitoring and proactive management of abnormalities that arise during HIPEC is imperative to decrease patient morbidity and mortality.

BACKGROUND: Surgical site infection after surgery for gynecologic cancer increases morbidity. Prophylactic closed incision negative pressure therapy has shown promise in reducing infectious wound complications across many surgical disciplines. OBJECTIVE: This study aimed to determine whether closed incision negative pressure therapy is associated with reduced surgical site infections in gynecologic oncology patients undergoing laparotomy compared with standard dressings. STUDY DESIGN: This was a retrospective case-control study of patients undergoing laparotomy for known or suspected gynecologic cancer from Jan. 1, 2017, to Feb. 1, 2020. Patients were matched in a 1:3 ratio (closed incision negative pressure therapy to standard dressing) by body mass index, age, diabetes, bowel surgery, smoking, and steroid use. Surgical site infection was defined according to the Centers for Disease Control and Prevention. Multivariable logistic regression using backward selection was performed. RESULTS: Of the 1223 eligible patients undergoing laparotomy, 64 (5.2%) received closed incision negative pressure therapy dressings and were matched to 192 (15.7%) controls. There were no differences in medical comorbidities (P>.05), site or stage of malignancy (P>.05), duration of surgery (P=.82), or surgical procedures (P>.05). Use of closed incision negative pressure therapy was associated with reduction in all adverse wound outcomes (20.3% vs 40.1%; P<.001). In particular, closed incision negative pressure therapy was associated with a significant reduction in both superficial incisional surgical site infections (9.4% vs 29.7%; P<.001) and deep incisional surgical site infections (0.0% vs 6.8%; P=.04). In multivariable analysis, use of closed incision negative pressure therapy was associated with significant reduction in the incidence of superficial incisional infections alone (odds ratio, 0.29; 95% confidence interval, 0.12-0.73; P=.008) and both superficial and deep incisional infections (odds ratio, 0.29; 95% confidence interval, 0.12-0.71; P=.007). CONCLUSION: Use of prophylactic closed incision negative pressure therapy after laparotomy in gynecologic oncology patients was found to be associated with reduced superficial incisional and deep incisional infections compared with standard dressings. Furthermore, closed incision negative pressure therapy was associated with reduction in all other adverse wound outcomes. Closed incision negative pressure therapy may be considered for surgical site infection prevention in high-risk gynecologic oncology patients undergoing laparotomy.

OBJECTIVE: To determine the efficacy of dalantercept, a soluble ALK1 inhibitor receptor fusion protein, in patients with persistent or recurrent ovarian carcinoma and related malignancies. METHODS: Eligibility criteria included measurable disease, 1-2 prior cytotoxic regimens and GOG performance status (PS) ≤2. Dalantercept was administered subcutaneously at 1.2â¯mg/kg every 3â¯weeks until disease progression or development of unacceptable toxicity. The primary null hypothesis was the probability of response ≤0.10 and the probability of 6-month progression-free survival without receipt of non-protocol therapy (event-free survival at 6â¯months, EFS6) ≤0.15, using RECIST 1.1 criteria. RESULTS: The first stage was closed after enrollment of 30 participants with median age of 56.5â¯years, high-grade serous histology in 76.7%, 2 prior regimens in 46.7%, and platinum-free interval <6â¯months in 73.3%. All participants discontinued dalantercept, 24 (80.0%), 5 (16.7%) and 1 (3.3%) due to progression, toxicity, and other reason, respectively. The median number of treatment cycles per patient was 2 (range 1-29). There were six treatment-related grade 3 AEs and no grade ≥4 AEs. There were no objective responses. EFS6 was reached in 20% (6 out of 30 participants, 90% CI 9.1% to 35.7%). CONCLUSIONS: Though safe, dalantercept as administered had limited efficacy in this patient population overall.
