RESUMO
OBJECTIVES: To evaluate procedures performed during primary debulking surgery (PDS) and interval debulking surgery (IDS) for ovarian cancer. METHODS: Patients surgically treated at our institution for newly diagnosed stage IIIC/IV epithelial ovarian cancer between 6/1/2015-12/31/2021 were identified using a prospectively collected database. Patients were triaged to PDS or neoadjuvant chemotherapy (NACT) followed by IDS using an institutional algorithm. Data on specific procedures performed, including consultants called, were collected from operative and pathology reports. Appropriate statistical analyses were applied. RESULTS: Overall, 467 patients underwent PDS and 434 underwent IDS; 76% (PDS) and 71% (IDS) of cases achieved complete gross resection. Comparing PDS vs IDS cohorts, median age was 63 years (range, 23-86) vs 67 years (range, 35-95), 79% vs 86% of patients had high-grade serous histology, and 38% vs 70% had stage IV disease. Most procedures (except ostomy, distal pancreatectomy) were more common during PDS (P < .05). Bowel surgery was performed during 65% of PDS and 33% of IDS, and upper abdominal surgery during 72% of PDS and 52% of IDS; both were more common during PDS (P < .001). Estimated blood loss (median, 500 mL [PDS] vs 300 mL [IDS]) and operative time (median, 362 min [PDS] vs 267 min [IDS]) were higher for PDS (P < .001). A consulting surgeon was utilized during 31% of PDS and 18% of IDS, with hepatopancreaticobiliary as the most commonly called service (61% and 65%, respectively). CONCLUSIONS: In our study of patients with advanced-stage ovarian cancer, while most procedures were more often performed during PDS, NACT did not obviate the need for radical surgical resection. Thus, advanced surgical skills remain essential.

OBJECTIVES: Mesonephric (MA) and mesonephric-like (MLA) adenocarcinomas are rare cancers, and data on clinical behavior and response to therapy are limited. We sought to report molecular features, treatment, and outcomes of MA/MLA from a single institution. METHODS: Patients with MA (cervix) or MLA (uterus, ovary, other) treated at Memorial Sloan Kettering Cancer Center (MSK) from 1/2008-12/2021 underwent pathologic re-review. For patients with initial treatment at MSK, progression-free survival (PFS1) was calculated as time from initial surgery to progression or death; second PFS (PFS2) was calculated as time from start of treatment for recurrence to subsequent progression or death. Overall survival (OS) was calculated for all patients. Images were retrospectively reviewed to determine treatment response. Somatic genetic alterations were assessed by clinical tumor-normal sequencing (MSK-Integrated Mutation Profiling of Actionable Cancer Targets [MSK-IMPACT]). RESULTS: Of 81 patients with confirmed gynecologic MA/MLA, 36 received initial treatment at MSK. Sites of origin included cervix (n = 9, 11%), uterus (n = 42, 52%), ovary (n = 28, 35%), and other (n = 2, 2%). Of the 36 patients who received initial treatment at MSK, 20 (56%) recurred; median PFS1 was 33 months (95% CI: 17-not evaluable), median PFS2 was 8.3 months (95% CI: 6.9-14), and median OS was 87 months (95% CI: 58.2-not evaluable). Twenty-six of the 36 patients underwent MSK-IMPACT testing, and 25 (96%) harbored MAPK pathway alterations. CONCLUSION: Most patients diagnosed with early-stage disease ultimately recurred. Somatic MAPK signaling pathway mutations appear to be highly prevalent in MA/MLA, and therapeutics that target this pathway are worthy of further study.

OBJECTIVES: To compare oncologic outcomes of secondary cytoreductive surgery (SCS) before and after FDA approval of Poly(ADP-ribose) polymerase inhibitor (PARPi) and bevacizumab maintenance therapies for platinum-sensitive recurrent ovarian cancer (PS-ROC). METHODS: Patients who underwent SCS for first recurrence of PS-ROC from 1/1/2013-1/1/2020 were identified. Exclusion criteria included prior chemotherapy for recurrence, bowel obstruction procedures, and palliative surgery. Data were dichotomized pre/post 1/2017, relative to FDA approval of PARPi and bevacizumab maintenance for ROC. Second progression-free survival (PFS2), the primary endpoint, was estimated using Kaplan-Meier method. RESULTS: Overall, 245 patients underwent SCS-131 (53%) pre- and 114 (47%) post-approval. Most patients had high-grade serous tumors (83% and 90%, respectively; p = 0.13). Deleterious BRCA1/2 alterations were identified in 27% (32/120) and 28% (32/113) of tested patients, respectively (p = 0.88). Disease-free intervals pre- and post-approval were: 6-12 months, 16% and 18%; 12-30 months, 56% and 59%; and >30 months, 28% and 24%, respectively (p = 0.73). Overall, 85% and 86% of patients, respectively, achieved complete gross resection (CGR; p > 0.99). PARPi maintenance use increased from 3.8% to 27% (p < 0.001) following approval, and bevacizumab from 1.5% to 12% (p < 0.001). Median PFS2 was 19 and 20.1 months, respectively. In the post group, 1-year PFS2 rate was 84.5% (95% CI, 75.7-90.4%) for patients with CGR vs 56.2% (95% CI, 29.5-76.2%) for those with residual disease; 3-year PFS2 rates were 31.3% (95% CI, 21.6-41.4%) and 12.5% (95% CI, 2.1-32.8%), respectively (p = 0.001). CONCLUSIONS: CGR during SCS is associated with improved PFS2 compared to suboptimal resection. Prospective randomized trials are warranted to elucidate the role of SCS as more therapeutics become available.

OBJECTIVE: To evaluate the theoretical impact of regionalizing cytoreductive surgery for ovarian cancer (OC) to high-volume facilities on patient travel. METHODS: We retrospectively identified patients with OC who underwent cytoreduction between 1/1/2004-12/31/2018 from the New York State Cancer Registry and Statewide Planning and Research Cooperative System. Hospitals were stratified by low-volume (<21 cytoreductive surgical procedures for OC annually) and high-volume centers (≥21 procedures annually). A simulation was performed; outcomes of interest were driving distance and time between the centroid of the patient's residence zip code and the treating facility zip code. RESULTS: Overall, 60,493 patients met inclusion criteria. Between 2004 and 2018, 210 facilities were performing cytoreductive surgery for OC in New York; 159 facilities (75.7%) met low-volume and 51 (24.3%) met high-volume criteria. Overall, 10,514 patients (17.4%) were treated at low-volume and 49,979 (82.6%) at high-volume facilities. In 2004, 78.2% of patients were treated at high-volume facilities, which increased to 84.6% in 2018 (P < .0001). Median travel distance and time for patients treated at high-volume centers was 12.2 miles (IQR, 5.6-25.5) and 23.0 min (IQR, 15.2-37.0), and 8.2 miles (IQR, 3.7-15.9) and 16.8 min (IQR, 12.4-26.0) for patients treated at low-volume centers. If cytoreductive surgery was centralized to high-volume centers, median distance and time traveled for patients originally treated at low-volume centers would be 11.2 miles (IQR, 3.8-32.3; P < .001) and 20.2 min (IQR, 13.6-43.0; P < .001). CONCLUSIONS: Centralizing cytoreductive surgery for OC to high-volume centers in New York would increase patient travel burden by negligible amounts of distance and time for most patients.

OBJECTIVE: To evaluate the feasibility and outcomes of performing procedural interventions, defined as surgical resection, tumor ablation, or targeted radiation therapy, for oligoprogressive disease among patients with gynecologic malignancies who are treated with immune checkpoint blockade. METHODS: Patients with gynecologic cancers treated with immune checkpoint blockade between January 2013 and October 2021 who underwent procedural interventions including surgical resection, interventional radiology ablation, or radiation therapy for oligoprogressive disease were identified. Procedures performed before immune checkpoint therapy initiation or ≥6 months after therapy completion were excluded. Long immunotherapy duration prior to intervention was defined as ≥6 months. Progression-free survival and overall survival were calculated from procedure date until disease progression or death, respectively. RESULTS: During the study period, 886 patients met inclusion criteria and received immune checkpoint blockade therapy. Of these, 34 patients underwent procedural interventions for oligoprogressive disease; 7 underwent surgical resection, 3 underwent interventional radiology ablation, and 24 underwent radiation therapy interventions. Primary disease sites included uterus (71%), ovary (24%), and cervix (6%). Sites of oligoprogression included abdomen/pelvis (26%), bone (21%), lung (18%), distant lymph node (18%), brain (9%), liver (6%), and vagina (3%). Most tumors (76%) did not exhibit microsatellite instability or mismatch repair deficiency. Approximately half (53%) of the patients had long immune checkpoint therapy duration prior to intervention. Median progression-free survival following the procedure was 5.3 months (95% CI, 3.1-9.9), and median overall survival was 21.7 months (95% CI, 14.9-not estimable). Long versus short immune checkpoint therapy duration prior to procedure and length of immune checkpoint therapy had no effect on progression-free or overall survival. CONCLUSIONS: Procedural interventions for patients with oligoprogression on immune checkpoint blockade therapy are feasible and demonstrate favorable outcomes. With expanding use of immune checkpoint therapy, it is important to investigate combined modalities to maximize therapeutic benefit for patients with gynecologic cancers.

BACKGROUND: Ovarian cancer with extensive metastatic disease involving pelvic structures often requires rectosigmoid resection for complete gross resection; however, it is associated with increased surgical morbidity. There are limited data, and none in ovarian cancer, on near-infrared assessment of perfusion in rectosigmoid resections with anastomosis. PRIMARY OBJECTIVE: To compare the rate of pelvic complications (pelvic abscesses, anastomotic leaks, and infections) within 30 days of surgery with and without near-infrared assessment of perfusion at time of rectosigmoid resection and re-anastomosis in patients undergoing cytoreductive surgery for ovarian cancer. STUDY HYPOTHESIS: We hypothesize the use of near-infrared technology (intravenous indocyanine green and endoscopic near-infrared fluorescence imaging), compared with standard intra-operative assessment, to evaluate anastomotic perfusion at time of rectosigmoid resection and re-anastomosis will result in lower rates of post-operative pelvic complications. TRIAL DESIGN: This is a planned multicenter randomized controlled trial. Patients who undergo rectosigmoid resection as part of their ovarian cytoreductive surgery will be randomized 1:1 to standard assessment of anastomosis with the surgeon's usual technique (control arm) or assessment with near-infrared angiography using indocyanine green and endoscopic fluorescence imaging (experimental arm). Randomization will occur after rectosigmoid resection has been completed and the surgeon declares their plan to create a diverting ostomy. Randomization will be stratified by plan for diverting ostomy. MAJOR INCLUSION/EXCLUSION CRITERIA: Main inclusion criteria include patients with primary or recurrent ovarian, fallopian tube, or primary peritoneal cancer who are scheduled for cytoreductive surgery with suspected need for low-anterior rectosigmoid resection. PRIMARY ENDPOINT: Rate of 30-day post-operative pelvic complications. SAMPLE SIZE: 310 (155 per arm) ESTIMATED DATES FOR COMPLETING ACCRUAL AND PRESENTING RESULTS: Q2 2027 and Q4 2027, respectively. TRIAL REGISTRATION: NCT04878094.

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.

Patients undergoing extensive lymph node dissection and radiation are at high risk for not only lymphedema but also painful contracture. In a standard lymphadenectomy, immediate lymphatic reconstruction using a lymphovenous bypass is effective in reconstructing the lymphatic defect. However, a more aggressive nodal clearance leaves the patient with a large cavity and skeletonized neurovascular structures, often resulting in severe contracture, pain, cosmetic deformity, and venous stricture. Adjuvant radiotherapy to the nodal bed can lead to severe and permanent disability despite physical therapy. Typically, these patients are referred to us after the fact, where surgery will rarely restore the patient to normal function. In an effort to avoid lymphedema and contracture, we have been reconstructing both the lymphatic and soft tissue defect during lymphadenectomy, using vascularized omentum lymphatic transplant (VOLT). A total of 13 patients underwent immediate reconstruction with VOLT at the time of axillary (nâ =â 8; 61.5%) or groin (nâ =â 5; 38.5%) dissection. No postoperative complications were observed. The mean follow-up time was 15.1â ±â 12.5 months. Only one lower extremity patient developed mild lymphedema (11% volume differential), with excellent scores in validated patient-reported outcomes. All patients maintained full range of motion with no pain. None of the 13 patients required a compression garment. Immediate lymphatic reconstruction with VOLT is a promising procedure for minimizing the risk of lymphedema and contracture in the highest risk patients undergoing particularly extensive lymph node dissection and radiotherapy.
RESUMO
Our study aims to identify the risk factors and dosimetry characteristics associated with capsular contracture. METHODS: We retrospectively analyzed 118 women with breast cancer who underwent PMRT following an IBR between 2010 and 2022. Patients were treated with PMRT of 50.0-50.4 Gy in 25-28 fractions. Capsular contracture was categorized according to the Baker Classification for Reconstructed Breasts. RESULTS: After a median follow-up of 22 months, the incidence of clinically relevant capsular contracture (Baker III-IV) was 22.9%. Overall, capsular contracture (Baker I-IV) occurred in 56 patients (47.5%) after a median of 9 months after PMRT. The rate of reconstruction failure/implant loss was 25.4%. In the univariate analysis, postoperative complications (prolonged pain, prolonged wound healing, seroma and swelling) and regional nodal involvement were associated with higher rates of capsular contracture (p = 0.017, OR: 2.5, 95% CI: 1.2-5.3 and p = 0.031, respectively). None of the analyzed dosimetric factors or the implant position were associated with a higher risk for capsular contracture. CONCLUSION: Postoperative complications and regional nodal involvement were associated with an increased risk of capsular contracture following breast reconstruction and PMRT, while none of the analyzed dosimetric factors were linked to a higher incidence. Additional studies are needed to identify further potential risk factors.
RESUMO
Whole-genome doubling (WGD) is a critical driver of tumor development and is linked to drug resistance and metastasis in solid malignancies. Here, we demonstrate that WGD is an ongoing mutational process in tumor evolution. Using single-cell whole-genome sequencing, we measured and modeled how WGD events are distributed across cellular populations within tumors and associated WGD dynamics with properties of genome diversification and phenotypic consequences of innate immunity. We studied WGD evolution in 65 high-grade serous ovarian cancer (HGSOC) tissue samples from 40 patients, yielding 29,481 tumor cell genomes. We found near-ubiquitous evidence of WGD as an ongoing mutational process promoting cell-cell diversity, high rates of chromosomal missegregation, and consequent micronucleation. Using a novel mutation-based WGD timing method, doubleTime , we delineated specific modes by which WGD can drive tumor evolution: (i) unitary evolutionary origin followed by significant diversification, (ii) independent WGD events on a pre-existing background of copy number diversity, and (iii) evolutionarily late clonal expansions of WGD populations. Additionally, through integrated single-cell RNA sequencing and high-resolution immunofluorescence microscopy, we found that inflammatory signaling and cGAS-STING pathway activation result from ongoing chromosomal instability and are restricted to tumors that remain predominantly diploid. This contrasted with predominantly WGD tumors, which exhibited significant quiescent and immunosuppressive phenotypic states. Together, these findings establish WGD as an evolutionarily 'active' mutational process that promotes evolvability and dysregulated immunity in late stage ovarian cancer.
