RESUMO
OBJECTIVES: We evaluated the performance of a chatbot compared to the National Comprehensive Cancer Network (NCCN) Guidelines for the management of ovarian cancer. METHODS: Using NCCN Guidelines, we generated 10 questions and answers regarding management of ovarian cancer at a single point in time. Questions were thematically divided into risk factors, surgical management, medical management, and surveillance. We asked ChatGPT (GPT-4) to provide responses without prompting (unprompted GPT) and with prompt engineering (prompted GPT). Responses were blinded and evaluated for accuracy and completeness by 5 gynecologic oncologists. A score of 0 was defined as inaccurate, 1 as accurate and incomplete, and 2 as accurate and complete. Evaluations were compared among NCCN, unprompted GPT, and prompted GPT answers. RESULTS: Overall, 48% of responses from NCCN, 64% from unprompted GPT, and 66% from prompted GPT were accurate and complete. The percentage of accurate but incomplete responses was higher for NCCN vs GPT-4. The percentage of accurate and complete scores for questions regarding risk factors, surgical management, and surveillance was higher for GPT-4 vs NCCN; however, for questions regarding medical management, the percentage was lower for GPT-4 vs NCCN. Overall, 14% of responses from unprompted GPT, 12% from prompted GPT, and 10% from NCCN were inaccurate. CONCLUSIONS: GPT-4 provided accurate and complete responses at a single point in time to a limited set of questions regarding ovarian cancer, with best performance in areas of risk factors, surgical management, and surveillance. Occasional inaccuracies, however, should limit unsupervised use of chatbots at this time.
RESUMO
OBJECTIVES: To develop a pre-operative tool to estimate the risk of peri-operative packed red blood cell transfusion in primary debulking surgery. METHODS: We retrospectively reviewed an institutional database to identify patients who underwent primary debulking surgery for ovarian cancer at a single center between January 1, 2001 and May 31, 2019. Receiver operating characteristic curve and area under the receiver operating characteristic curve (AUC) were calculated. Five-fold cross-validation was applied to the multivariate model. Significant variables were assigned a 'BLOODS' (BLood transfusion Over an Ovarian cancer Debulking Surgery) score of +1 if present. A total BLOODS score was calculated for each patient, and the odds of receiving a transfusion was determined for each score. RESULTS: Overall, 1566 patients met eligibility criteria; 800 (51%) underwent a peri-operative blood transfusion. Odds ratios (OR) were statistically significant for American Society of Anesthesiologists scores of 3 and 4 (OR 1.34, 95% confidence interval (95% CI) 1.09 to 1.63), pre-operative levels of cancer antigen 125 (CA125) (OR 2.43, 95% CI 1.98 to 2.99), platelets (OR 1.59, 95% CI 1.45 to 1.74), obesity (OR 0.76, 95% CI 0.60 to 0.96), presence of carcinomatosis (OR 2.45, 95% CI 1.93 to 3.11), bulky upper abdominal disease (OR 2.86, 95% CI 2.32 to 3.54), pre-operative serum albumin level (OR 0.31, 95% CI 0.24 to 0.40), and pre-operative hemoglobin level (OR 0.56, 95% CI 0.51 to 0.61). The corrected AUC was 0.748 (95% CI 0.693 to 0.804). BLOODS scores of 0 and 5 corresponded to 11% and 73% odds, respectively, of receiving a peri-operative blood transfusion. CONCLUSIONS: We developed a universal pre-operative scoring system, the BLOODS score, to help identify patients with ovarian cancer who would benefit from surgical planning and blood-saving techniques. The BLOODS score was directly proportional to the American Society of Anesthesiologists score, presence of upper abdominal disease, carcinomatosis, CA125 level, and platelets level. We believe this model can help physicians with surgical planning and can benefit patient outcomes.

BACKGROUND: Treatment options for patients with platinum-resistant/refractory ovarian cancers are limited and only marginally effective. The development of novel, more effective therapies addresses a critical unmet medical need. Olvimulogene nanivacirepvec (Olvi-Vec), with its strong immune modulating effect on the tumor microenvironment, may provide re-sensitization to platinum and clinically reverse platinum resistance or refractoriness in platinum-resistant/refractory ovarian cancer. PRIMARY OBJECTIVE: The primary objective is to evaluate the efficacy of intra-peritoneal Olvi-Vec followed by platinum-based chemotherapy and bevacizumab in patients with platinum-resistant/refractory ovarian cancer. STUDY HYPOTHESIS: This phase III study investigates Olvi-Vec oncolytic immunotherapy followed by platinum-based chemotherapy and bevacizumab as an immunochemotherapy evaluating the hypothesis that such sequential combination therapy will prolong progression-free survival (PFS) and bring other clinical benefits compared with treatment with platinum-based chemotherapy and bevacizumab. TRIAL DESIGN: This is a multicenter, prospective, randomized, and active-controlled phase III trial. Patients will be randomized 2:1 into the experimental arm treated with Olvi-Vec followed by platinum-doublet chemotherapy and bevacizumab or the control arm treated with platinum-doublet chemotherapy and bevacizumab. MAJOR INCLUSION/EXCLUSION CRITERIA: Eligible patients must have recurrent, platinum-resistant/refractory, non-resectable high-grade serous, endometrioid, or clear-cell ovarian, fallopian tube, or primary peritoneal cancer. Patients must have had ≥3 lines of prior chemotherapy. PRIMARY ENDPOINT: The primary endpoint is PFS in the intention-to-treat population. SAMPLE SIZE: Approximately 186 patients (approximately 124 patients randomized to the experimental arm and 62 to the control arm) will be enrolled to capture 127 PFS events. ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: Expected complete accrual in 2024 with presentation of primary endpoint results in 2025. TRIAL REGISTRATION: NCT05281471.

BACKGROUND: Patients undergoing cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) are frequently admitted to the intensive care unit (ICU) for mitigation of potential complications, although ICU length of stay (LOS) is a significant driver of cost. This study asked whether a fiscal argument could be made for the selective avoidance of ICU admission after CRS/HIPEC. METHODS: Prospective data for select low-risk patients (e.g., lower peritoneal cancer index [PCI]) admitted to the intermediate care unit (IMC) instead of the ICU after CRS/HIPEC were matched with a historic cohort routinely admitted to the ICU. Cohort comparisons and the impact of the intervention on cost were assessed. RESULTS: The study matched 81 CRS/HIPEC procedures to form a cohort of 49 pre- and 15 post-intervention procedures for patients with similar disease burdens (mean PCI, 8 ± 6.7 vs. 7 ± 5.1). The pre-intervention patients stayed a median of 1 day longer in the ICU (1 day [IQR, 1-1 day] vs. 0 days [IQR, 0-0 days]) and had a longer LOS (8 days [IQR, 7-11 days] vs. 6 days [IQR, 5.5-9 days]). Complications and complication severity did not differ statistically. The median total hospital cost was lower after intervention ($30,845 [IQR, $30,181-$37,725] vs. $41,477 [IQR, $33,303-$51,838]), driven by decreased indirect fixed cost ($8984 [IQR, $8643-$11,286] vs. $14,314 [IQR, $12,206-$18,266]). In a weighted multiple variable linear regression analysis, the intervention was associated with a savings of $2208.68 per patient. CONCLUSIONS: Selective admission to the IMC after CRS/HIPEC was associated with $2208.68 in savings per patient without added risk. In this era of cost-conscious practice of medicine, these data highlight an opportunity to decrease cost by more than 5% for patients undergoing CRS/HIPEC.

OBJECTIVES: To examine postoperative complications associated with preoperative mechanical and oral antibiotic bowel preparation (MOABP) for patients with ovarian cancer who underwent bowel resection at cytoreductive surgery (CRS). METHODS: This was a single-institution retrospective study of patients with ovarian cancer undergoing CRS from 01/2011-12/2020 using ICD-10 diagnoses and procedure codes. Patients were stratified by those who underwent bowel resection versus no resection. Bowel resection patients were further stratified by those who underwent MOABP versus no bowel preparation. Patient demographics, tumor data, and perioperative metrics were collected. Unadjusted and adjusted logistic regression evaluated odds of 30-day postoperative complications in patients with bowel resection versus no resection and those with MOABP versus no bowel preparation. RESULTS: Of 919 patients identified, 215 (23.3%) required bowel resection, which included 81 (37.7%) who received MOABP. Patient characteristics, co-morbidities, and cancer data were similar between MOABP versus no bowel preparation patients. MOABP patients underwent more interval CRS (34.6% versus 9.0%), more optimal surgical resections (96.3% versus 83.8%), fewer diverting ostomies (13.5% versus 33.5%), and shorter hospital stays (7.1 versus 9.4 days) than no bowel preparation patients. On adjusted analyses, MOABP patients experienced significantly lower odds of deep/organ-space surgical infections and 30-day readmissions but higher odds of unplanned intensive care unit (ICU) admissions and grade 3 or higher cardiac and gastrointestinal complications. CONCLUSIONS: Patients who underwent preoperative MOABP prior to ovarian cancer CRS with bowel resection had lower odds or deep/organ-space infections and readmissions, shorter hospital stays, fewer diverting ostomies, and more optimal resections. However, these patients also experienced higher odds of ICU admissions and grade 3 or higher cardiac and gastrointestinal complications. The positive and negative postoperative outcomes in this population should be considered in clinical practice.

OBJECTIVES: We describe post-operative complications after cytoreductive surgery with and without splenectomy for Stage III or IV epithelial ovarian cancer, and identify areas for quality improvement in post-splenectomy care. METHODS: All patients with ovarian cancer cytoreductive surgery from 2008 to 2018 were identified using an institutional database Gynecologic Oncology Longitudinal Data Collection and Utilization Program (GOLD CUP). We compared patients who had and did not have splenectomy as part of cytoreductive surgery by demographics, comorbidities, stage, operative and post-operative data, readmission rates, progression free survival, overall survival and death from disease. Quality metrics reported include receipt of post-splenectomy education handouts and encapsulated-organism vaccines. Statistical analysis was completed in STATA SE 16.0. RESULTS: We identified 47 patients who underwent splenectomy and 454 who did not during primary or interval cytoreductive surgery. Final stage was IIIB in 1 (2.1%), IIIC in 26 (55.3%), IVA in 7 (14.9%), and IVB in 13 (27.7%) patients. Those with splenectomy had significantly higher stage. Surgery duration and hospital length of stay were longer and blood transfusion more common after splenectomy, but there were no differences in post-operative infection, readmission, or overall survival. Pancreatic leaks were seen in 4/47 (8.5%) patients. Post-splenectomy vaccinations were documented in 42/47 (89.4%) patients. Only 2/47 (4.3%) received post-splenectomy discharge instructions and 3/7 (42.9%) received aspirin for platelets 1 million or more. CONCLUSIONS: While splenectomy adds morbidity, it continues to offer benefit in those patients who can achieve optimal cytoreduction. Areas for quality improvement in post-splenectomy care include receipt of vaccinations, patient discharge information, and timely pancreatic fistula management.

There is increasing evidence that many endometrial cancers (EC) diagnosed as clear cell carcinoma (CCC) have substantial overlap with both serous carcinoma (SC) and endometrioid carcinoma (EmC), not only in terms of morphology and immunophenotype but also by molecular characterization. Now with use of HER2-based therapy in SC, a CCC diagnosis in serous-like tumors has the potential to exclude patients from receiving beneficial therapy. To assess HER2 in CCC in relation to other characteristics, a tissue microarray of archived CCC, EmC, and SC was stained for HER2 alongside a battery of immunostains used in EC. Cases with equivocal HER2 IHC were also assessed by in situ hybridization. HER2 status was assessed in 229 cases (23 CCC, 74 SC, 132 EmC). HER2 was positive in 48% of cases diagnosed as CCC, 19% of SC, and 0% of EmC. Rigorous morphologic and immunophenotypic review by 5 gynecologic pathologists revealed diagnostic disagreement in 8/11 HER2+ cases diagnosed as CCC, with SC as the other major diagnostic consideration. All HER2+ (n=25) cases were MMR-intact and most HER2+ EC had aberrant p53 staining (22/25, 88%); the 3 cases with a wild type pattern for p53 (12%) were all negative for ER. Based on these findings, patients with a diagnosis of CCC should be included in future clinical trials of HER2-targeted therapy. Moreover, given the diagnostic difficulty surrounding CCC, immunohistochemistry-based algorithms that include aberrant p53 and/or the absence of ER expression may provide a more objective means of establishing eligibility criteria than is currently possible using traditional histologic classification.

OBJECTIVES: To determine if linear measurements of adiposity from pre-operative imaging can improve anticipation of surgical difficulty among endometrial cancer patients. METHODS: Eighty patients with newly diagnosed endometrial cancer were enrolled. Routine pre-operative imaging (MRI or CT) was performed. Radiologic linear measurements of the following were obtained: anterior-to-posterior skin distance; anterior skin to anterior edge of L5 distance (total anterior); anterior peritoneum to anterior edge of L5 distance (visceral obesity); and posterior edge of L5 to posterior skin distance (total posterior). Surgeons completed questionnaires quantifying preoperative anticipated operative difficulty and postoperative reported operative difficulty. The primary objective was to assess for a correlation between linear measurements of visceral fat and reported operative difficulty. RESULTS: Seventy-nine patients had questionnaires completed, preoperative imaging obtained, and surgery performed. Univariate analysis showed all four linear measurements, body mass index, weight, and anticipated operative difficulty were associated with increased reported operative difficulty (P< 0.05). Multivariate analysis demonstrated that body mass index and linear measurements visceral obesity and total posterior were independently associated with increased reported operative difficulty (P< 0.05). Compared with body mass index, the visceral obesity measurement was more sensitive and specific for predicting increased reported operative difficulty (visceral obesity; sensitivity 54%, specificity 91 %; body mass index; sensitivity 38%, specificity 89%). A difficulty risk model combining body mass index, visceral obesity, and total posterior demonstrated better predictive performance than any individual preoperative variable. CONCLUSIONS: Simple linear measurements of visceral fat obtained from preoperative imaging are more predictive than body mass index alone in anticipating surgeon-reported operative difficulty. These easily obtained measurements may assist in preoperative decision making in this challenging patient population.

BACKGROUND: Women with a gynecologic cancer tend to be older, obese, and postmenopausal, characteristics that are associated with an increased risk for obstructive sleep apnea. However, there is limited investigation regarding the condition's prevalence in this population or its impact on postoperative outcomes. In other surgical populations, patients with obstructive sleep apnea have been observed to be at increased risk for adverse postoperative events. OBJECTIVE: We sought to estimate the prevalence of obstructive sleep apnea among gynecologic oncology patients undergoing elective surgery and to investigate for a relationship between obstructive sleep apnea and postoperative outcomes. STUDY DESIGN: Patients referred to an academic gynecologic oncology practice were approached for enrollment in this prospective, observational study. Patients were considered eligible for study enrollment if they were scheduled for a nonemergent inpatient surgery and could provide informed consent. Enrolled patients were evaluated for a preexisting diagnosis of obstructive sleep apnea. Those without a prior diagnosis were screened using the validated, 4-item STOP questionnaire (ie, Snore loudly, daytime Tiredness, Observed apnea, elevated blood Pressure). All patients who screened positive for obstructive sleep apnea were referred for polysomnography. The primary outcome was the prevalence of women with obstructive sleep apnea or those who screened at high risk for the condition. Secondary outcomes examined the correlation between body mass index (kg/m2) with obstructive sleep apnea and assessed for a relationship between obstructive sleep apnea and postoperative outcomes. RESULTS: Over a 22-month accrual period, 383 eligible patients were consecutively approached to participate in the study. A cohort of 260 patients were enrolled. A total of 33/260 patients (13%) were identified as having a previous diagnosis of obstructive sleep apnea. An additional 66/260 (25%) screened at risk for the condition using the STOP questionnaire. Of the patients who screened positive, 8/66 (12%) completed polysomnography, all of whom (8/8 [100%]) were found to have obstructive sleep apnea. The prevalence of previously diagnosed obstructive sleep apnea or screening at risk for the condition increased as body mass index increased (P < .001). Women with untreated obstructive sleep apnea and those who screened at risk for the condition were found to have an increased risk for postoperative hypoxemia (odds ratio, 3.5; 95% confidence interval, 1.8-4.7; P = .011) and delayed return of bowel function (odds ratio, 2.1; 95% confidence interval, 1.3-4.5; P = .009). CONCLUSION: The prevalence of obstructive sleep apnea or screening at risk for the condition is high among women presenting for surgery with a gynecologic oncologist. Providers should consider evaluating a patient's risk for obstructive sleep apnea in the preoperative setting, especially when risk factors for the condition are present.

STUDY OBJECTIVE: To study the safety, feasibility, learning curve, and surgical outcome for single-port laparoscopic full staging of endometrial cancer. DESIGN: A retrospective study (Canadian Task Force classification II-3). SETTING: A university academic hospital. PATIENTS: Women with endometrial cancer undergoing single-port laparoscopic full surgical staging. INTERVENTIONS: This was a single-center, retrospective consecutive study of patients undergoing single-port laparoscopic full staging of endometrial cancer from March 2012 to December 2015. MEASUREMENTS AND MAIN RESULTS: One hundred ten consecutive cases were included in the study. The mean age was 63 years (standard deviation = 14), and the mean body mass index was 34 kg/m2 (standard deviation = 7). Medical comorbidity was noted in 62% (68/110) of patients, and 55% (61/110) of patients had previous abdominal surgery. Preoperative histology included grade 1 (63%), grade 2 (23%), grade 3 (4%), papillary serous (6%), clear cell (3%), and mixed (1%). Postoperatively, 73% of patients were stage I, 2% were stage II, 21% were stage III, and 4% were stage IV. The conversion rate to multiple ports or to laparotomy was 6.3%. The average total surgical time was 186 minutes. Comparing the last 30 cases of our cohort with the first 20, there was a significant improvement in the reduction of the total operative time (191 vs 152 minutes, p = .036), estimated blood loss (389 vs 121 mL, p = .002), conversion rate (20 % vs 0%, p = .02), and rate of surgical complication (10% vs. 0%, p = .03). The readmission rate was 11% (12/110) with 75% of those patients being readmitted for surgical indications and 25% for medical indications. The rate of ventral hernia was 1.8% (2/110) with an average follow-up of 298 days (31-1085 days). CONCLUSION: Single-port laparoscopic staging of endometrial cancer is a safe and feasible technique to introduce into a gynecologic oncology practice that is compatible with other minimally invasive modalities with similar complication rates, discharge timing, and operative times. Drastic improvement in surgical time can be seen after approximately the first 20 cases.

OBJECTIVE: To quantify the impact of perioperative ß blocker use on survival after primary cytoreductive surgery for epithelial ovarian cancer. METHODS: We conducted a multi-center retrospective study of all women who underwent primary cytoreductive surgery for ovarian cancer (2000-2010). One institution had routinely used perioperative ß blockers for patients "at risk" for coronary events. The other institution did not routinely use perioperative ß blockers. Demographic, operative, and follow up data were collected. Cox proportional hazards models were used to assess the effect of ß blockers on progression-free interval (PFI) as well as overall survival (OS). RESULTS: Out of 185 eligible patients, 70 received ß blockers and 115 underwent cytoreductive surgery without perioperative ß blockers. Both groups were similar in demographics. A history of hypertension was present more often in the ß blocker group compared to the group that did not receive ß blockers (22% and 6%, p=0.002). PFI in ß blocker group was greater at 18.2 vs. 15.8months (p=0.66). The OS in the ß blocker group was significantly higher at 44.2 vs. 39.3months (p=0.01). In multivariate analysis, perioperative ß blocker use was associated with significant improvement in OS (HR 0.68 (0.46-0.99); p=0.046). CONCLUSION: Our study showed an association between perioperative ß blocker use and longer overall survival in patients undergoing primary ovarian cancer cytoreductive surgery. A prospective randomized clinical trial in this population would further validate these results.

STUDY OBJECTIVE: To determine the complications associated with single-incision laparoscopy in gynecologic oncology surgery. DESIGN: A retrospective cohort (Canadian Task Force classification II-3). SETTING: A single academic institution. PATIENTS: One hundred fifteen consecutive patients undergoing single-incision laparoscopy with suspected gynecologic oncology conditions. INTERVENTIONS: Single-incision laparoscopy. MEASUREMENTS AND MAIN RESULTS: One hundred fifteen patients underwent single-incision laparoscopy. The mean age was 55.3 ± 13.1 years. For procedures completed via single-incision laparoscopy (102/115 [88.7%]), the mean operative time was 130.7 ± 55.5 minutes. The average blood loss was 63 ± 111 mL. The conversion to open rate was 13 of 115 (12.17%). The conversion rate of the 55 patients with benign conditions was lower (2/55 [3.64%]) compared with the 60 patients with malignant conditions (11/60 [18.33%]). The hernia rate was 2 of 115 (1.80%), 1 of which was a recurrent hernia. The median time for follow-up was 30 days (range, 5-653 days). CONCLUSION: Single-incision laparoscopy provides a feasible, safe, and promising minimally invasive modality for treating gynecologic oncology patients.

OBJECTIVE: SSI rates after gynecologic oncology surgery vary from 5% to 35%, but are up to 45% in patients with diabetes mellitus (DM). Strict postoperative glucose control by insulin infusion has been shown to lower morbidity, but not specifically SSI rates. Our project studied continuous postoperative insulin infusion for 24h for gynecologic oncology patients with DM and hyperglycemia with a target blood glucose of <139 mL/dL and a primary outcome of the protocol's impact on SSI rates. METHODS: We compared SSI rates retrospectively among three groups. Group 1 was composed of patients with DM whose blood glucose was controlled with intermittent subcutaneous insulin injections. Group 2 was composed of patients with DM and postoperative hyperglycemia whose blood glucose was controlled by insulin infusion. Group 3 was composed of patients with neither DM nor hyperglycemia. We controlled for all relevant factors associated with SSI. RESULTS: We studied a total of 372 patients. Patients in Group 2 had an SSI rate of 26/135 (19%), similar to patients in Group 3 whose rate was 19/89 (21%). Both were significantly lower than the SSI rate (43/148, 29%) of patients in Group 1. This reduction of 35% is significant (p = 0.02). Multivariate analysis showed an odd ratio = 0.5 (0.28-0.91) in reducing SSI rates after instituting this protocol. CONCLUSIONS: Initiating intensive glycemic control for 24h after gynecologic oncology surgery in patients with DM and postoperative hyperglycemia lowers the SSI rate by 35% (OR = 0.5) compared to patients receiving intermittent sliding scale insulin and to a rate equivalent to non-diabetics.

OBJECTIVE: The objective of our study was to determine the predictive value of preoperative pelvic MRI and serum cancer antigen-125 (CA-125) evaluation in selecting women with grade 1 endometrial cancer for lymphadenectomy as part of the cancer staging operation. MATERIALS AND METHODS: A new preoperative clinical protocol including MRI and CA-125 evaluation was adopted at our institution in patients with grade 1 endometrioid adenocarcinoma. Lymphadenectomy was considered as part of the surgical staging operation if there was an elevated CA-125 value or a positive MRI finding (≥ 50% myometrial invasion, cervical invasion, abnormal lymph nodes, extrauterine disease, or tumor index ≥ 36 cm). From January 2012 through May 2013, a retrospective analysis was performed of 100 women who underwent preoperative MRI and CA-125 evaluation; we refer to this cohort as the "preoperative study cohort." The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated using final surgical pathology and CA-125 results as the reference standard. The rate of metastatic lymph nodes in the preoperative study cohort was determined. From May 2009 through January 2011, a retrospective analysis of a cohort who did not undergo preoperative MRI and CA-125 evaluation was undertaken to compare lymphadenectomy and lymph node metastasis rates before and after implementation of the new protocol; we refer to this cohort as the "historical cohort." RESULTS: The new clinical protocol had sensitivity of 94%, specificity of 91%, PPV of 84%, and NPV of 97%. When histologic grade alone was considered, positive lymph node rates in the preoperative study cohort was 4.0% versus 4.2% in the historical cohort. In the preoperative study cohort, the lymph node metastasis rate increased to 11.1% with a positive MRI finding or elevated CA-125 value. CONCLUSION: Preoperative MRI and CA-125 evaluation identified women for lymphadenectomy with a high NPV.

OBJECTIVES: The prompt diagnosis of postoperative pulmonary embolism (PE) in gynecologic oncology patients is imperative, but the clinical presentation is nonspecific in this high-risk group. We sought to determine risk factors and clinical findings that may assist clinicians in diagnosing PE in the inpatient setting. METHODS: Radiology data were queried to identify patients with gynecologic cancer who had a postoperative PE evaluation with computed tomography pulmonary angiography (CT-PA). Patient clinical findings at the time of the PE evaluation were abstracted, and univariate and multivariate regression analyses were performed to identify predictors of PE. RESULTS: For 6 years, there were 2498 major gynecologic oncology surgical procedures performed at our institution. Within 14 days of surgery, 107 CT-PA studies were obtained with a positive study rate of 24.3%. In patients with and without PE, there was no significant difference noted for age, oxygen saturations, body mass index and heart rate. After controlling for stage, history of venous thromboembolism (VTE), heart rate, and oxygen saturation, platelet count (odds ratio, 1.26 per 50 counts increase; 95% confidence interval, 1.07-1.48; P = 0.006) and history of VTE (odds ratio, 17.1; 95% confidence interval, 1.77-Inf, P = 0.014) were identified as independent predictors of PE in the multivariate model. CONCLUSIONS: Although clinicians often use tachycardia and low oxygen saturation as triggers to order PE imaging studies, these signs have a very low specificity. Given the findings of our study, accounting for high platelet count and history of VTE increases the pretest probability of CT-PA study.

OBJECTIVE: To quantify the impact of preoperative hypoalbuminemia on 30-day mortality and morbidity after gynecologic cancer surgery. METHODS: Patients included in the National Surgical Quality Improvement Program (NSQIP) dataset who underwent any non-emergent surgery for gynecologic malignancy between 1/1/2008 and 12/31/2010 were identified. Analysis was conducted with albumin both as a dichotomous variable (<3.5 g/dl was defined as low albumin) and as a continuous variable to determine a clinically relevant cut-off value. RESULTS: Of the total 3171 patients identified, 2110 had preoperative albumin levels available for analysis. In addition, 279 (13.3%) of these patients had low albumin levels. According to multivariate analysis, the low albumin group had significantly higher odds of developing one or more post-operative complications (OR-2,CI: 1.47-2.73, p<0.0001), three or more complications (OR-4.1,CI: 2.31-7.1, p<0.0001), surgical complications (OR-2.39,CI: 1.59-3.58, p<0.0001), thromboembolic complications (OR-2.59,CI: 1.33-5.06, p<0.0001), pulmonary complications (OR-4.06,CI: 2.05-8.03, p<0.0001), or infectious complications (OR-1.84,CI: 1.26-2.69, p<0.0001) and a higher 30-day mortality (OR-6.52,CI: 2.51-16.95, p<0.0001). Upon subgroup analysis, this difference was not found in patients undergoing laparoscopic surgery. In patients undergoing open surgery, the probability of experiencing one or more post-operative complications increased linearly with the decrease in albumin level; however, the probability of patients experiencing three or more complications and 30-day mortality increased sharply as soon as the albumin level decreased below 3g/dl. CONCLUSION: Preoperative albumin levels <3g/dL identify a population of patients at a very high-risk of experiencing perioperative morbidity and 30-day mortality after open surgery.

Objectives: This study sought to compare differences in blood transfusion and surgical complication rates before and after the implementation of a restrictive blood transfusion protocol. Methods: On July 1, 2018, our institution implemented a restrictive blood transfusion protocol utilizing a hemoglobin trigger of less than 7 g/dL. Retrospective chart review was completed to review patients undergoing major abdominal surgery by the gynecology and gynecologic oncology services 18 months before, and after initiation of the transfusion protocol. Outcomes included number of patients, units transfused and postoperative complication rates. Complications included reoperation on the day of admission, surgical site infections, wound disruptions, pulmonary, renal, central nervous system, and cardiovascular complications, as well as deep venous thromboses, readmissions, and 30-day mortality. Results: There were 290 people in the pre- and 449 patients in the post-protocol group. A similar number of patients received blood transfusions in both groups (9.3% versus 10.6% p = 0.57). However, significantly fewer units of blood were given post-protocol initiation. For every patient who received a transfusion pre-protocol, 2.66 units were administered compared to 1.2 units after the protocol was initiated (p = 0.003). All postoperative complications were not significantly different between groups (p > 0.05). Individual postoperative complications were combined and analyzed using a clustered approach to detect rates of complications more conservatively. Both the 7-system (5.1% versus 4.9%, p = 0.90) and 8-system (5.5% versus 4.9%, p = 0.72) clustered analyses were not significantly different before and after the initiation of the transfusion protocol. Conclusions: A restrictive transfusion protocol is effective in decreasing the number of units of blood transfused without affecting postoperative complication rates in gynecologic surgery patients.
RESUMO
OBJECTIVE: The objective of this study is to identify factors associated with receiving surgical menopause counseling in gynecologic cancer patients, as well as patient and provider perspectives, regarding surgical menopause counseling and management. METHODS: We conducted a single-institution mixed-method study combining retrospective chart review and patient and provider surveys. Patients younger than 51 years who experienced surgical menopause after gynecologic cancer treatment from January 2017 to December 2019 were surveyed in April 2021 about experiences with menopause counseling, barriers to care, and quality of life. We then reviewed charts of only patients who fully completed surveys. All gynecologic oncology providers were surveyed about surgical menopause practices. Logistic regression identified factors associated with receiving counseling. RESULTS: Sixty-six of 75 identified met inclusion criteria and received survey invitations. Thirty-five (53%) completed surveys. Sixty percent had documented surgical menopause counseling. Patients who were counseled were younger (43 vs 48.5 years, P = 0.005), more likely to have referrals for menopause care (12 vs 9, P = 0.036), more likely to have menopause providers other than oncology providers (14 vs 8, P = 0.001), and had fewer comorbidities. Decreasing age at surgery increased odds of counseling. Most reported continued menopause symptoms and quality of life disturbances. Half were satisfied with menopause care. Majority preferred counseling from oncology providers. Most providers always counseled on surgical menopause but cited lack of time as the primary obstacle for complete counseling. CONCLUSIONS: Younger age at surgery increased odds of receiving surgical menopause counseling. Gynecologic cancer patients experienced significant menopause-related disturbances. Improved understanding of patient and provider preferences and greater emphases on surgical menopause and survivorship will improve care for gynecologic oncology patients.

Objective: Little data exists to adequately counsel patients on the postsurgical morbidity and outcomes of an aborted primary debulking (AD) for advance stage epithelial ovarian cancer. Our objectives were to examine the 30-day morbidity of AD, percentage of patients who subsequently undergo neoadjuvant chemotherapy (NACT) and interval cytoreductive surgery (ICS), residual disease at ICS, and predictors for complications after AD. Methods: This was a single-institution retrospective analysis of patients who underwent AD for ovarian cancer from 01/2008 to 12/2020 using ICD-10 diagnoses and procedure codes. Patient demographics, perioperative metrics, and residual disease at ICS were collected. Thirty-day postoperative complications were graded by the Common Terminology Criteria for Adverse Events. Fisher's exact tests compared categorical and Wilcoxon rank-sum tests compared continuous variables. Logistic regression provided unadjusted odds ratios to identify predictors for post-AD complications. Results: Forty-eight patients underwent AD, and 43 were included for analysis. All had at least stage IIIC high grade serous ovarian cancer. All patients subsequently underwent ICS, with 21 (48.8%) achieving no residual macroscopic disease and 21 (48.8%) to ≤ 1 cm of macroscopic disease. After AD, 16 (37.2%) experienced at least one G ≥ 3 event within the first 30 days. The most common complication was gastrointestinal complications. Preoperative albumin was the only significant predictor for G ≥ 3 complication after AD. Conclusions: Approximately one-third of patients will experience at least one G ≥ 3 complications after AD. Complications may be anticipated by low preoperative albumin. Patients can be counseled that, after AD, proceeding to subsequent NACT and ICS and achieving optimal debulking is common.
