IntroductionLow grade serous ovarian carcinoma (LGSOC) is a rare subtype of ovarian cancer (OC) that is challenging to treat due to its relative chemoresistance. Given that LGSOC patients often recur in the peritoneal cavity, novel intraperitoneal (IP) chemotherapy should be explored. Pressurized intraperitoneal aerosolized chemotherapy (PIPAC) is a method that has demonstrated peritoneal disease control in cancers with peritoneal metastases.MethodsNCT04329494 is a US multicenter phase 1 trial evaluating the safety of PIPAC in recurrent ovarian, uterine, and GI cancers with peritoneal metastases. This analysis describes the outcomes of a sub-cohort of four LGSOC patients treated with IP cisplatin 10.5 mg/m2, doxorubicin 2.1 mg/m2 PIPAC q4-6 weeks. Primary endpoints included dose-limiting toxicities (DLT) and incidence of adverse events (AE). Secondary endpoints were progression free survival (PFS) and treatment response based on radiographic, intraoperative, and pathological findings.ResultsFour patients with LGSOC were enrolled of which three were heavily pretreated. Median prior lines of therapy was 5 (range 2-10). Three patients had extraperitoneal metastases, and two patients had baseline partial small bowel obstructive (SBO) symptoms. Median age of patients was 58 (38-68). PIPAC completion rate (≥2 PIPACs) was 75%. No DLTs or Clavien-Dindo surgical complications occurred. No G4/G5 AEs were observed, and one G3 abdominal pain was reported. One patient had a partial response after 3 cycles of PIPAC and completed an additional 3 cycles with compassionate use amendment. Two patients came off study after 2 cycles due to extraperitoneal progressive disease. One patient came off study after 1 cycle due to toxicity. Median decrease in peritoneal carcinomatosis index between cycles 1 and 2 was 5.0%. Ascites decreased in 2 out of 3 patients who had ≥2 PIPACs. Median PFS was 4.3 months (1.7-21.6), median overall survival was 11.6 months (5.4-30.1), and objective response rate was 25%.ConclusionPIPAC with cisplatin/doxorubicin is well tolerated in LGSOC patients without baseline SBO symptoms. IP response was seen in 2 out of 3 patients that completed ≥2 PIPAC cycles. Further study of PIPAC for patients with recurrent disease limited to the IP cavity and with no partial SBO symptoms should be considered.

Objective. Platinum-resistant epithelial ovarian cancer (EOC), recurrent endometrial cancer (EC), and triple negative breast cancer (TNBC) are difficult to treat after failing standard therapies. This phase I study evaluated mirvetuximab soravtansine (MIRV) and gemcitabine in patients with recurrent FR alpha-positive EOC, EC, or TNBC to determine the maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D) (primary endpoint). Methods. FR alpha-positive patients with platinum-resistant EOC, EC, or TNBC with <= 4 prior chemotherapy regimens (2 for EC) were enrolled. FR alpha expression requirement varied among eligible tumors and changed during the study. Results. Twenty patients were enrolled; 17 were evaluable for DLT. Half the patients received >= 3 prior chemotherapy lines. Most EOC and EC patients (78%) were medium (50-74%) or high(75-100%) FR alpha expressors. TNBC patients were low (25-49%) FR alpha expressors. The MTD/RP2D was MIRV 6 mg/kg AIBW D1 and gemcitabine 800 mg/m2 IV, D1 and D8, every 21 days (Dose Level [DL] 3), where 5/7 patients demonstrated a partial response (PR) as their best response, including 2 confirmed ovarian responses whose time-to-progression and duration of response were 7.9/5.4 and 8.0/5.7 months respectively. Most common treatment-related adverse events at MTD were anemia and neutropenia (3/7 each, 43%), diarrhea, hypophosphatemia, thrombocytopenia, and leukopenia (2/7 each, 29%). DLTs were thrombocytopenia (DL1), oral mucositis (DL4) and diarrhea (DL4). Nine of 20 patients (45%; 95% CI: 21.1-68.9%) achieved PR as their best response, with 3/20 patients or 15% (95%CI, 0-32.1%) confirmed PR. Conclusion. MIRV and gemcitabine demonstrate promising activity in platinum resistant EOC at RP2D, but frequent hematologic toxicities.

Hyperthermic intraperitoneal chemotherapy (HIPEC) with cisplatin confers a survival benefit in epithelial ovarian cancer (EOC) but is associated with renal toxicity. Sodium thiosulfate (ST) is used for nephroprotection for HIPEC with cisplatin, but standard HIPEC practices vary. A prospective, nonrandomized, clinical trial evaluated safety outcomes of HIPEC with cisplatin 75 mg/m2 during cytoreductive surgery (CRS) in patients with EOC (n = 34) and endometrial cancer (n = 6). Twenty-one patients received no ST (nST), and 19 received ST. Adverse events (AEs) were reported according to CTCAE v.5.0. Serum creatinine (Cr) was collected preoperatively and postoperatively (Days 5–8). Progression-free survival (PFS) was followed. Normal peritoneum was biopsied before and after HIPEC for whole transcriptomic sequencing to identify RNAseq signatures correlating with AEs. Forty patients had HIPEC at the time of interval or secondary CRS. Renal toxicities in the nST group were 33

PURPOSE Hyperthermic intraperitoneal chemotherapy (HIPEC) confers a survival benefit in epithelial ovarian cancer (EOC) and in preclinical models. However, the molecular changes induced by HIPEC have not been corroborated in humans. PATIENTS AND METHODS A feasibility trial evaluated clinical and safety outcomes of HIPEC with cisplatin during optimal cytoreductive surgery (CRS) in patients with EOC diagnosed with stage III, IV, or recurrent EOC. Pre- and post-HIPEC biopsies were comprehensively profiled with genomic and transcriptomic sequencing to identify mutational and RNAseq signatures correlating with response; the tumor microenvironment was profiled to identify potential immune biomarkers; and transcriptional signatures of tumors and normal samples before and after HIPEC were compared to investigate HIPEC-induced acute transcriptional changes. RESULTS Thirty-five patients had HIPEC at the time of optimal CRS; all patients had optimal CRS. The median progression-free survival (PFS) was 24.7 months for primary patients and 22.4 for recurrent patients. There were no grade 4 or 5 adverse events. Anemia was the most common grade 3 adverse event (43%). Hierarchical cluster analyses identified distinct transcriptomic signatures of good versus poor responders to HIPEC correlating with a PFS of 29.9 versus 7.3 months, respectively. Among good responders, significant HIPEC-induced molecular changes included immune pathway upregulation and DNA repair pathway downregulation. Within cancer islands, % programmed cell death protein 1 expression in CD8+ T cells significantly increased after HIPEC. An exceptional responder (PFS 58 months) demonstrated the highest programmed cell death protein 1 increase. Heat shock proteins comprised the top differentially upregulated genes in HIPEC-treated tumors. CONCLUSION Distinct transcriptomic signatures identify responders to HIPEC, and preclinical model findings are confirmed for the first time in a human cohort.

INTRODUCTION AND HYPOTHESIS:At our institution, every patient seen by the gynecologic oncology service is screened for pelvic floor dysfunction. This study was aimed at determining if a combined surgical approach by gynecologic oncology and urogynecology services at our institution was feasible and safe for this patient population.METHODS:We performed a retrospective review of patients undergoing combined surgery by gynecologic oncology and urogynecology services at our institution from 2013 to 2021. Perioperative variables, postoperative adverse events, and long-term outcomes were assessed, and descriptive statistics were performed.RESULTS:From 20 December 2013 to 29 January 2021, a total of 102 patients underwent concurrent surgical repair of pelvic organ prolapse and/or stress urinary incontinence. Seventy-three patients (71.6%) had normal/benign pathologic conditions, and 29 (28.4%) had premalignant/malignant pathologic conditions. Ten patients (9.8%) had a postoperative complication, including reoperation for exposed midurethral sling (4.9%), urinary retention requiring midurethral sling release (2.9%), reoperation for hemoperitoneum (1.0%), and anemia requiring blood transfusion (1.0%). Nine complications occurred in patients with benign/normal pathologic conditions (12.3%), and one complication occurred in patients with pre-malignant/malignant pathologic conditions (3.4%).CONCLUSIONS:In our single-institution experience, concurrent gynecologic oncology and pelvic floor reconstructive surgery were safe and feasible in combination with no reported major morbidity events.

Objectives: To demonstrate safety and tolerability of HIPEC in ovarian cancer. Methods: A phase I, single-institution feasibility study was designed to evaluate the safety and feasibility of HIPEC at time of optimal cytoreductive surgery (CRS) in ovarian cancer patients, followed by optional normothermic intraperitoneal chemotherapy, at City of Hope National Comprehensive Cancer Center (Duarte, CA). Primary endpoint of the trial was to evaluate the safety and feasibility of HIPEC at time of optimal cytoreductive surgery (CRS). Progression-free survival was a secondary end-point. Exploratory endpoints included the assessment of molecular markers in tumors. Eligibility criteria included epithelial ovarian cancer (stage III or IV), primary or recurrent, ECOG 0-1, and appropriate surgical candidates. 35 patients were enrolled between 2015 and 2019, who underwent optimal CRS (gross residual disease less than 1 cm), and received HIPEC intra-operatively with cisplatin at 75 mg/m2 for 60 minutes immediately following optimal CRS. Patients were stratified as either 1) primary disease (n=19), defined as having received HIPEC at time of interval CRS following neoadjuvant chemotherapy for primary EOC; 2) recurrent disease (n=16), defined as having received HIPEC at time of interval or upfront CRS for recurrent (salvage) EOC. Adjuvant chemotherapy was given at the discretion of the treating oncologist following HIPEC. Results: Median age was 58 years (36-74 years), with a mean BMI of 26. Primary (interval) patients represented 54% of patients, with pretreatment clinical stages III (53%) and IV (47%). Recurrent (salvage) patients represented 45.7%, with platinum-sensitive (75%) and platinum-resistant (25%). The most common histological subtype was high grade serous (69%). All primary (interval) patients underwent neoadjuvant chemotherapy (3-4 cycles) prior to interval CRS and HIPEC. The majority of recurrent patients (81%) did not receive neo-adjuvant chemotherapy. Thirty-three patients underwent closed technique and two underwent laparoscopic technique. Total mean operating time was 8.4 hours (4.6-15.3). Mean length of stay was 10 days (3-30). All patients underwent optimal cytoreduction (69% with complete R0 resection). Peritoneal carcinomatosis index (PCI) ranged 2 to 30 (median of 8). Patients with PCI < 8 had significantly improved PFS of 26.9 months compared to PCI >/= 8 whose PFS was 12.6 (p=0.04). Time to initiation of adjuvant chemotherapy in recurrent patients was 8.4 weeks. 22.9% of the ovarian cancer cohort was gBRCA mutated. Median PFS for primary patients was 12.6 months (95% CI 6.4; NR); with median follow up of 22.1 months (95% CI 12.6, 31.5). Median PFS for recurrent patients was 18.8 months (95% CI 7.2; 28.7), with median follow up of 36.3 months (95% CI 21.1, 51.5). There were no grade 4 or 5 AEs. Anemia was the most common Grade 3 AE (43%), followed by liver dysfunction and electrolyte abnormalities. The most common AE of any grades were abdominal pain (86%), anemia (77%), and nausea (66%). Two patients (6%) had grade 3 acute kidney injury and one patient had grade 3 chronic kidney disease. Sodium thiosulfate was introduced to the trial in January 2018, following which there were no grade 1-4 acute or chronic kidney injuries. Conclusions: HIPEC in ovarian cancer was well tolerated, without any grade 4 or 5 AEs. Renal toxicities were mitigated with sodium thiosulfate. Patients with a low PCI (< 8) had better PFS than those with PCI >/= 8. To demonstrate safety and tolerability of HIPEC in ovarian cancer.

This report presents our experience in performing prolapse repair after anterior exenteration. The patient had a history of invasive bladder cancer and underwent a robotically assisted laparoscopic anterior exenteration with extended bilateral pelvic lymph node dissection and creation of an Indiana pouch continent diversion. Her pelvic organ prolapse progressed over time despite multiple pessary fittings. She eventually decided to proceed with pelvic reconstructive surgery 6 years after her cancer surgery. She underwent a successful vaginal native tissue reconstruction with uterosacral ligament suspension, posterior repair and reconstruction of the anterior compartment. The patient has been followed for 16 months without recurrent prolapse. Vaginal native tissue pelvic reconstruction is feasible in a patient with a history of pelvic exenteration.

Immunotherapy is emerging as one of the most effective methods for treating many cancers. However, immunotherapy can still introduce significant off-target toxicity, and methods are sought to enable targeted immunotherapy at tumor sites. Here, we show that relatively large (>100-nm) anionic nanoparticles administered intraperitoneally (i.p.) selectively accumulate in tumor-associated macrophages (TAMs). In a mouse model of metastatic ovarian cancer, fluorescently labeled silica, poly(lactic-co-glycolic acid), and polystyrene nanoparticles administered i.p. were all found to selectively accumulate in TAMs. Quantifying silica particle uptake indicated that >80% of the injected dose was in TAMs. Particles that were smaller than 100 nm or cationic or administered intravenously (i.v.) showed no TAM targeting. Moreover, this phenomenon is likely to occur in humans because when freshly excised human surgical samples were treated with the fluorescent silica nanoparticles no interaction with healthy tissue was seen but selective uptake by TAMs was seen in 13 different patient samples. Ovarian cancer is a deadly disease that afflicts ∼22,000 women per year in the United States, and the presence of immunosuppressive TAMs at tumors is correlated with decreased survival. The ability to selectively target TAMs opens the door to targeted immunotherapy for ovarian cancer.

Background Immunogenic cell death has been suggested as a mechanism for HIPEC, through the release of heat shock proteins, and resulting in activation of tumor-specific T cells. Methods This is a subgroup analysis of a Phase I trial using HIPEC with cisplatin 75 mg/m2 at time of optimal cytoreduction. Metastatic tumors from nine ovarian cancer patients were collected intraoperatively before and after HIPEC. Differentially expressed genes and pathways of pre- and post-HIPEC tumors were analyzed via whole-transcriptome sequencing (WTS). Immunofluorescent (IF) staining and multispectral imaging were used to determine composition and PD-1 expression of CD8+ and conventional CD4+ tumor-infiltrating lymphocytes (TILs), using antibodies against CD8, FOXP3, PD-1, and pancytokeratin (to distinguish cancer islands from stroma). Kaplan-Meier and log-rank tests compared the overall and progression free survivals (PFS) of patients with low versus high%PD-1 changes, based on dichotomization with respect to the median%PD-1 change. Results Heatshock proteins comprised the top differentially upregulated genes in HIPEC-treated tumors. Gene set enrichment analysis revealed significant upregulation of immune pathways, including antigen processing/presentation. IF staining demonstrated increased%PD-1 in cancer islands of CD8+ and CD4+ TILs after HIPEC. In stroma, the largest%PD-1 change occurs in an exceptional responder (PFS, OS 5 years), while the lowest%PD-1 change occurred in a poor responder. Kaplan-Meier curves demonstrate superior PFS in patients with high stromal PD-1 changes in TILs after HIPEC. Conclusions Increased PD-1 expression after HIPEC suggests early HIPEC-induced T cell activation, and is associated with improved survival, implicating a potential future role for PD-1 inhibitors following HIPEC in ovarian cancer.

Mirvetuximab soravtansine (MIRV) is an ADC comprising a FRα-binding antibody, linked to the tubulin-disrupting maytansinoid DM4. MIRV has promising single agent activity in FRα-positive epithelial ovarian cancer (EOC), at 6 mg/kg, based on adjusted ideal body weight (AIBW) IV every (q) 21 days. Clinical data in other FRα-positive solid tumors has been limited. This study is evaluating MIRV and G in recurrent EOC, EC and triple negative breast cancer (TNBC). The recommended phase II dose (RP2D) reported at ASCO 2019, was established at DL3 (MIRV 6 mg/kg AIBW IV, day 1 and G 800 mg/m2 IV, d1, 8) q21 days. Here we report the results in the EC cohort treated at the RP2D. Pts with FRα-positive EC with ≤ 2 prior chemotherapy (CT) regimens are eligible. FRα positivity by immunohistochemistry was initially defined as ≥25% of cells with PS2+ staining intensity (low to high FRα levels) and was subsequently revised to ≥ 50% of cells with PS2+ (medium/high FRα levels, with high defined as ≥ 75% of cells with PS2+). The expansion cohort of 12 pts with FRα-positive EC treated at the RP2D pre-specified that ≥ 2 responders are required to declare the combination promising. From October 2017 to May 2020, 55 EC pts underwent FRα screening, with 4 results pending. Out of 51 EC pts with results, 12 pts (23.5%) have medium/high FRα levels with 5 pts (9.8%) have low FRα level. 5 EC pts were treated at the RP2D (1 too early and 4 evaluable for response of which 1 pt had medium FRα and 3 pts had low FRα). 2 of the 4 evaluable EC pts at the RP2D achieved a partial response (PR). 1 PR was observed on cycle 7 (the only medium FRα level pt) and the second PR was on cycle 3. One pt. had SD after 4 cycles and remains on treatment, and 1 pt progressed in the 1st cycle. Grade (G) 3-4 adverse events (AEs) in the 4 evaluable pts treated at the RP2D were infrequent and included: Gr 4 lymphopenia (1 pt), Gr 3 ANC/WBC/PLT (1 pt), and Gr 3 HTN and lymphopenia (1pt). The combination of MIRV with G has promising clinical activity in FRα-positive EC. The regimen is tolerable with the expected treatment related AEs of these agents.

Evaluation of safety is of paramount importance with adoption of novel surgical technology. Although robotic surgery has become widely used in oncologic surgery, analysis of safety is lacking in comparison to traditional techniques. Standardized assessment of robotic surgical outcomes and adverse events following oncologic surgery is necessary for quality improvement with innovative technology. Between 2003 and 2016, 10,013 unique robotic operations were performed in 9,858 patients. Our prospectively maintained database was retrospectively reviewed for hospital readmissions and Clavien–Dindo grade ≥ 2 complications within 30 days. Multivariable logistic regression was used to identify predictors of surgical complications and hospital readmissions. Cases were stratified by discipline: genitourinary (n = 8240), gynecologic (n = 857), thoracic (n = 457), gastrointestinal (n = 322), hepatobiliary (n = 60), ear/nose/throat (n = 44) and general (n = 33). Intraoperative complications occurred in 42 surgeries (0.4%). Postoperative complications occurred in 946 patients [9.4%, highest grade 2 (n = 574), 3 (n = 288), 4 (n = 72), 5 (n = 10)]. Most frequent complications were ileus (154, 16.3%), anemia (91, 9.6%), cardiac arrhythmia (62, 6.6%), deep vein thrombosis/pulmonary embolus (47, 5.0%), wound infection (45, 4.8%) and urinary leak (43, 4.5%). 405 patients (4.0%) required readmission. Most common causes for hospital readmission were ileus (44, 10.9%), urinary leak (23, 5.7%), urinary tract infection (23, 5.7%), intra-abdominal abscess/fluid collection (23, 5.7%), and small bowel obstruction (19, 4.7%). On multivariable analysis, longer operative time and older age predicted complications and readmissions (p ≤ 0.02). Robotic-assisted surgery appears a safe for oncologic surgery with acceptable hospital readmission and complication rates. Older age and longer operative time were associated with complications and readmission.

To evaluate intraperitoneal (IP) nab-paclitaxel in patients with advanced malignancies that are primarily confined to the peritoneal cavity in a phase I trial. Using a 3 + 3 dose escalation of IP nab-paclitaxel on days 1, 8, and 15 of a 28-day cycle, we evaluated six dose levels (35–175 mg/m2/dose). Maximum tolerated dose (MTD) and pharmacokinetics (PK) of IP nab-paclitaxel were determined. There were no dose-limiting toxicities (DLTs) in cohorts 1–3. There was a DLT in one of six patients in cohort 4 (112.5 mg/m2) (grade 3 neutropenia causing treatment delay > 15 days) and a DLT in one of three patients in cohort 6 (175 mg/m2) (grade 4 neutropenia and grade 3 abdominal pain). A second patient in cohort 6 experienced a serious adverse event (cycle 1, grade 4 ANC ≤ 7 days, cycle 4, grade 2 left ventricular dysfunction). This dose level was determined to be above the MTD. No DLTs were seen in seven patients treated in cohort 5 (140 mg/m2). The MTD of IP nab-paclitaxel was established at 140 mg/m2 on days 1, 8, and 15 of a 28-day cycle. There was a PK advantage for IP nab-paclitaxel, with an IP plasma area under the concentration–time curve (AUC) ratio of 147-fold (range 50–403) and therapeutic range systemic drug levels. Eight of 27 enrolled patients had progression-free survival ≥ 6 months. One patient experienced complete response, and one patient experienced partial response. Six patients had stable disease. Weekly IP nab-paclitaxel has a favorable toxicity profile, a significant pharmacologic advantage, and promising clinical activity. NCT00825201.

The NCCN Guidelines for Survivorship provide screening, evaluation, and treatment recommendations for common physical and psychosocial consequences of cancer and cancer treatment to help healthcare professionals who work with survivors of adult-onset cancer in the posttreatment period. This portion of the guidelines describes recommendations regarding the management of anthracycline-induced cardiotoxicity and lymphedema. In addition, recommendations regarding immunizations and the prevention of infections in cancer survivors are included.

Background and Objectives: Cytoreductive surgery with complete macroscopic resection in patients with ovarian cancer is associated with improved survival. Institutional reports of combined upper and lower abdominal cytoreductive surgery for more advanced disease have described multidisciplinary approaches. We sought to investigate outcomes in patients undergoing cytoreductive surgery in patients with upper and lower abdominal disease at our institution. Methods: Patients who underwent cytoreductive surgery for ovarian malignancies from 2008 to 2015 were retrospectively identified from an institutional database. Upper abdominal cytoreduction was defined anatomically as debulking of disease proximal to the ligament of Treitz. Perioperative outcomes were analyzed. Results: A total of 258 operations were performed, the majority for serous ovarian carcinoma (70%). The gynecologic oncologist was the primary surgeon and often assisted by either a surgical oncology fellow and/or attending. In operations with combined upper and lower abdominal cytoreduction, patients were more likely to have an American society of anesthesiologists physical status classification system (ASA) of 3, peritoneal implants, and liver/spleen metastases. Preoperative chemotherapy and optimal cytoreduction were similar between groups. Perioperative morbidity and mortality were not significantly different between groups. Conclusions: A collaborative surgical approach to combined upper and lower abdominal cytoreductive surgery in patients with ovarian cancer should be performed, if needed, to achieve an optimal cytoreduction.

INTRODUCTION AND HYPOTHESIS:We present our experience in performing concurrent prolpase repair at the time of gynecologic cancer surgery.METHODS:The uterosacral ligaments are tagged before performing hysterectomy and pelvic dissection. The uterosacral ligament suspensory sutures are then placed laparoscopically after completion of pelvic cancer surgery. The remainder of the prolapse surgery is performed through a transvaginal approach.RESULTS:Many of our patients who undergo concurrent prolapse repair and gynecolgical cancer surgery receive chemotherapy and pelivc radiation. Concuurent prolapse repair improves their prolaspe symptoms.CONCLUSION:Concurrent prolapse repair should be performed at the same time as gynecologic cancer surgery.
