NRG/RTOG 0837: Randomized, phase II, double-blind, placebo-controlled trial of chemoradiation with or without cediranib in newly diagnosed glioblastoma.

Background: A randomized, phase II, placebo-controlled, and blinded clinical trial (NCT01062425) was conducted to determine the efficacy of cediranib, an oral pan-vascular endothelial growth factor receptor tyrosine kinase inhibitor, versus placebo in combination with radiation and temozolomide in newly diagnosed glioblastoma. Methods: Patients with newly diagnosed glioblastoma were randomly assigned 2:1 to receive (1) cediranib (20 mg) in combination with radiation and temozolomide; (2) placebo in combination with radiation and temozolomide. The primary endpoint was 6-month progression-free survival (PFS) based on blinded, independent radiographic assessment of postcontrast T1-weighted and noncontrast T2-weighted MRI brain scans and was tested using a 1-sided Z test for 2 proportions. Adverse events (AEs) were evaluated per CTCAE version 4. Results: One hundred and fifty-eight patients were randomized, out of which 9 were ineligible and 12 were not evaluable for the primary endpoint, leaving 137 eligible and evaluable. 6-month PFS was 46.6% in the cediranib arm versus 24.5% in the placebo arm (P = .005). There was no significant difference in overall survival between the 2 arms. There was more grade ≥ 3 AEs in the cediranib arm than in the placebo arm (P = .02). Conclusions: This study met its primary endpoint of prolongation of 6-month PFS with cediranib in combination with radiation and temozolomide versus placebo in combination with radiation and temozolomide. There was no difference in overall survival between the 2 arms.

The effect of older age on treatment outcomes in women with advanced ovarian cancer receiving chemotherapy: An NRG-Oncology/Gynecologic Oncology Group (GOG-0182-ICON5) ancillary study.

OBJECTIVE: To assess the effect of age on overall survival (OS) in women with ovarian cancer receiving chemotherapy. Secondary objectives were to describe the effect of age on treatment compliance, toxicities, progression free survival (PFS), time from surgery to chemotherapy, and rates of optimal cytoreduction. METHODS: Women enrolled in GOG 0182-ICON5 with stage III or IV epithelial ovarian cancer (EOC) who underwent surgery and chemotherapy between 2001 and 2004 were included. Patients were divided into ages <70 and ≥ 70 years. Baseline characteristics, treatment compliance, toxicities, and clinical outcomes were compared. RESULTS: We included a total of 3686 patients, with 620 patients (16.8%) ≥ 70 years. OS was 37.2 months in older compared to 45.0 months in younger patients (HR 1.21, 95% CI, 1.09-1.34, p < 0.001). Older patients had an increased risk of cancer-specific-death (HR 1.16, 95% CI, 1.04-1.29) as well as non-cancer related deaths (HR 2.78, 95% CI, 2.00-3.87). Median PFS was 15.1 months in older compared to 16.0 months in younger patients (HR 1.10, 95% CI, 1.00-1.20, p = 0.056). In the carboplatin/paclitaxel arm, older patients were just as likely to complete therapy and more likely to develop grade ≥ 2 peripheral neuropathy (35.7 vs 19.7%, p < 0.001). Risk of other toxicities remained equal between groups. CONCLUSIONS: In women with advanced EOC receiving chemotherapy, age ≥ 70 was associated with shorter OS and cancer specific survival. Older patients receiving carboplatin and paclitaxel reported higher rates of grade ≥ 2 neuropathy but were not more likely to suffer from other chemotherapy related toxicities.

Extraordinary clinical response to ibrutinib in low-grade ovarian cancer guided by organoid drug testing.

Low-grade serous ovarian cancer (LGSOC) typically responds poorly to standard platinum-based chemotherapy and new therapeutic approaches are needed. We describe a remarkable response to targeted therapy in a patient with platinum-resistant, advanced LGSOC who had failed standard-of-care chemotherapy and two surgeries. The patient was in rapid decline and entering hospice care on home intravenous (i.v.) opioid analgesics and a malignant bowel obstruction requiring a G-tube. Genomic analysis of the patient's tumor did not indicate obvious therapeutic options. In contrast, a CLIA-certified drug sensitivity assay of an organoid culture derived from the patient's tumor identified several therapeutic choices, including Bruton's tyrosine kinase (BTK) inhibitor ibrutinib, as well as the EGFR inhibitors afatinib and erlotinib. Following off-label administration of daily ibrutinib as monotherapy, the patient had an exceptional clinical turnaround over the following 65 weeks with normalization of CA-125 levels, resolution of the malignant bowel obstruction, halting of pain medications, and improvement of performance status from ECOG 3 to ECOG 1. After 65 weeks of stable disease, the patient's CA-125 levels began to rise, at which point the patient discontinued ibrutinib and began taking afatinib as monotherapy. The patient's CA-125 levels remained stable for an additional 38 weeks but due to anemia and rising CA-125 levels, the patient switched to erlotinib and is currently being monitored. This case highlights the clinical utility of ex vivo drug testing of patient-derived tumor organoids as a new functional precision medicine approach to identify effective personalized therapies for patients who have failed standard-of-care treatments.

Timing and duration of bevacizumab treatment and survival in patients with recurrent ovarian, fallopian tube, and peritoneal cancer: a multi-institution study.

Bevacizumab has demonstrated significant benefit in recurrent ovarian, fallopian tube and peritoneal cancer (OC), but its optimal position within the sequence of systemic therapies remains controversial. Since rebound progression after bevacizumab has been observed in other cancers, and because bevacizumab is incorporated in several regimens used in the recurrent setting, the duration of treatment may impact survival. We sought to identify whether earlier bevacizumab exposure is associated with prolonged bevacizumab therapy and survival by conducting a multi-institution retrospective study of recurrent OC patients treated with bevacizumab from 2004-2014. Multivariate logistic regression identified factors associated with receiving more than six bevacizumab cycles. Overall survival by duration and ordinal sequence of bevacizumab therapy were evaluated using logrank testing and Cox regression. In total, 318 patients were identified. 89.1% had stage III or IV disease; 36% had primary platinum resistance; 40.5% received two or fewer prior chemotherapy regimens. Multivariate logistic regression demonstrated that primary platinum sensitivity (Odds Ratio (OR) 2.34, p = 0.001) or initiating bevacizumab at the first or second recurrence (OR 2.73, p < 0.001) were independently associated with receiving more than six cycles of bevacizumab. Receiving more cycles of bevacizumab was associated with improved overall survival whether measured from time of diagnosis (logrank p < 0.001), bevacizumab initiation (logrank p < 0.001), or bevacizumab discontinuation (logrank p = 0.017). Waiting one additional recurrence to initiate bevacizumab resulted in a 27% increased hazard of death (Hazard Ratio (HR) 1.27, p < 0.001) by multivariate analysis. In conclusion, patients with primary platinum sensitive disease who received fewer prior lines of chemotherapy were able to receive more cycles of bevacizumab, which was associated with improved overall survival. Survival worsened when bevacizumab was initiated later in the ordinal sequence of therapies.

Participation of Patients With Limited English Proficiency in Gynecologic Oncology Clinical Trials.

BACKGROUND: Significant disparities exist in recruitment of minorities to clinical trials, with much of the prior literature focused on race/ethnicity only. Limited English proficiency (LEP) is a known barrier in healthcare that may also drive disparities in trial enrollment. We sought to determine participation rates in gynecologic oncology trials among patients with LEP and to explore barriers to their participation. METHODS: In a retrospective cohort study, electronic health record data from >2,700 patients treated over 2 years at one academic gynecologic oncology practice were abstracted and the primary exposure of having LEP was identified. The primary outcome was enrollment in a clinical trial. Demographic, financial, clinical, and healthcare access-related covariates were also abstracted and considered as potential confounders in a multivariable logistic regression model. Age, race, ethnicity, and insurance status were further examined for evidence of effect modification. In addition, a survey was administered to all gynecologic oncology research staff and gynecologic oncology providers (n=25) to assess barriers to research participation among patients with LEP. RESULTS: Clinical trial enrollment was 7.5% among fluent English speakers and 2.2% among patients with LEP (risk ratio, 0.29; 95% CI, 0.11-0.78; P=.007), and remained significantly lower in patients with LEP after adjusting for the identified confounders of Hispanic ethnicity and insurance payer (odds ratio, 0.34; 95% CI, 0.12-0.97; P=.043). There was a trend toward race and LEP interaction: Asian patients were equally likely to participate in research regardless of language fluency, whereas White and Black patients with LEP were less likely to participate than non-LEP patients in both groups (P=.07). Providers reported that the most significant barriers to enrollment of patients with LEP in research were unavailability of translated consent forms and increased time needed to enroll patients. CONCLUSIONS: Patients with LEP were 3.4 times less likely to participate in gynecologic oncology trials than fluent English speakers. De-aggregation of race, ethnicity, and language proficiency yielded important information about enrollment disparities. These findings offer avenues for future interventions to correct disparities.

Uterine lavage identifies cancer mutations and increased TP53 somatic mutation burden in individuals with ovarian cancer.

Current screening methods for ovarian cancer (OC) have failed to demonstrate a significant reduction in mortality. Uterine lavage combined with TP53 ultra-deep sequencing for the detection of disseminated OC cells has emerged as a promising tool, but this approach has not been tested for early-stage disease or non-serous histologies. In addition, lavages carry multiple background mutations, the significance of which is poorly understood. Uterine lavage was collected preoperatively in 34 patients undergoing surgery for suspected ovarian malignancy including 14 patients with benign disease and 20 patients with OC (6 non-serous and 14 high grade serous-like (serous)). Ultra-deep duplex sequencing (~3000x) with a panel of common OC genes identified the tumor mutation in 33% of non-serous (all early stage) and in 79% of serous cancers (including four early stage). In addition, all lavages carried multiple somatic mutations (average of 25 mutations per lavage), more than half of which corresponded to common cancer driver mutations. Driver mutations in KRAS, PIK3CA, PTEN, PPP2R1A and ARID1A presented as larger clones than non-driver mutations and with similar frequency in lavages from patients with and without OC, indicating prevalent somatic evolution in all patients. Driver TP53 mutations, however, presented as significantly larger clones and with higher frequency in lavages from individuals with OC, suggesting that TP53-specific clonal expansions are linked to ovarian cancer development. Our results demonstrate that lavages capture cancer cells, even from early-stage cancers, as well as other clonal expansions and support further exploration of TP53 mutation burden as a potential OC risk factor.

NCCN Guidelines® Insights: Ovarian Cancer, Version 3.2022.

Epithelial ovarian cancer is the leading cause of death from gynecologic cancer in the United States, with less than half of patients living >5 years following diagnosis. The NCCN Guidelines for Ovarian Cancer provide recommendations for the diagnosis, evaluation, treatment, and follow-up for patients with ovarian, fallopian tube, and primary peritoneal cancers. These NCCN Guidelines Insights summarize the panel discussion behind recent important updates to the guidelines, including revised guidance on alternative chemotherapy regimens for patients with advanced age and/or comorbidities, a new algorithm for recurrent low-grade serous carcinoma based on developing research and novel therapeutic agents, and updated language regarding tumor molecular analysis applications in ovarian cancer.

OVARIO phase II trial of combination niraparib plus bevacizumab maintenance therapy in advanced ovarian cancer following first-line platinum-based chemotherapy with bevacizumab.

OBJECTIVE: To assess safety and efficacy of niraparib + bevacizumab as a first-line maintenance therapy for patients with newly diagnosed advanced ovarian cancer. METHODS: This multicenter, phase II, single-arm, open-label study enrolled adult patients with stage IIIB to IV ovarian, fallopian tube, or primary peritoneal cancer (NCT03326193). Patients were required to have an attempt at debulking surgery and have a complete response, partial response, or no evidence of disease following first-line, platinum-based chemotherapy with ≥3 cycles of bevacizumab. The primary endpoint was the progression-free survival (PFS) rate at 18 months. Secondary endpoints included PFS, overall survival, and safety. RESULTS: Among the 105 evaluable patients, the PFS rate at 18 months was 62% (95% CI 52-71%) in the overall population and 76% (95% CI 61-87) in the homologous recombination deficient (HRd), 47% (95% CI 31-64%) in the HR proficient (HRp), and 56% (95% CI 31-79%) in the HR not determined (HRnd) subgroups (December 24, 2020, cutoff). After a median follow-up time of 28.7 months (IQR, 23.9-32.5 months), median PFS was 19.6 months (95% CI 16.5-25.1) in the overall population (N = 105) and 28.3 months (95% CI 19.9-NE), 14.2 months (95% CI 8.6-16.8), and 12.1 months (95% CI 8.0-NE) in the HRd, HRp, and HRnd subgroups, respectively (June 16, 2021, cutoff). The most common any-grade treatment-related adverse events (related to niraparib and/or bevacizumab) were thrombocytopenia (74/105), fatigue (60/105), and anemia (55/105; December 24, 2020, cutoff). CONCLUSION: Niraparib + bevacizumab first-line maintenance therapy displayed promising PFS results. Safety was consistent with the known safety profiles of niraparib and bevacizumab as monotherapy.

Cognitive skill training improves memory, function, and use of cognitive strategies in cancer survivors.

BACKGROUND: Cancer survivors commonly report symptoms of impaired cognition. This project examined effectiveness of a behavioral skills training intervention to improve cognition and reduce cognitive dysfunction symptoms in cancer survivors. METHODS: Participants were randomly assigned to group-based workshops focused on learning new cognitive skills (skills treatment-TX) or an active control of education workshops (education control-EC) or a passive control of wait list (WL). Participants were evaluated pre- and post intervention with subjective mood and symptom questionnaires and objective neurocognitive tests. RESULTS: One hundred twenty-eight participants (mean age 59 years), average 4.6 years (+ / - 5.5 years) post cancer treatment with various cancer types (breast, bladder, prostate, colon, uterine), were enrolled. Analysis of all participants who attended workshop(s) revealed improvement in the TX workshop completers on all objective cognitive measures (attention, concentration, declarative, and working memory) save one test of selective attention, and improvement on a single measure (verbal memory) and decline (selective attention) in the EC group. TX workshop completers also improved on all symptom and mood measures, in contrast to EC group which improved on a single subscale of a symptom measure, but increased on an anxiety measure. TX group alone improved on a quantified measure of each participants' unique, "top three," self-described cognitive symptoms. CONCLUSION: Improvement from behavioral skills training was evident from objective cognitive tests, subjective symptom measures, and quantified, individual patient-specific symptoms. Behavioral skill training is an effective treatment for cognitive dysfunction in cancer survivors, and should be considered as a treatment option by health care providers.

Characterization of the Early Years of Bevacizumab Use for First-Line Treatment of Ovarian Cancer in the United States.

PURPOSE: To quantify early dissemination patterns, factors influencing use, and costs of bevacizumab (BEV) for the treatment of newly diagnosed ovarian cancer (OC) in the United States before its regulatory approval for this indication (off-label use). METHODS: We identified women 18-65 years of age with newly diagnosed OC treated with surgery and platinum-based chemotherapy from 2008 to 2016 through the MarketScan database (N = 8,109). The proportion of women receiving BEV over time was calculated, multivariate logistic regression used to determine factors associated with BEV use, and total costs per cycle of chemotherapy with and without BEV abstracted. RESULTS: BEV utilization rose 1.8-fold during the study period, from 4.1% (2008) to 7.4 % (2016). BEV was used with non-platinum/taxane regimens over a third of the time (37.2%). Physician specialty (medical oncology v gyn oncology) and geography (southeast region) were significantly associated with higher rates of use. Clinical factors associated with BEV use were metastatic disease and presence of ascites. The median cost of one cycle of platinum/taxane chemotherapy plus BEV was $10,897 in US dollars (USD) (interquartile range $7,573-$18,133 USD), compared with $1,629 USD (interquartile range, $683.0-$4,461 USD) for platinum/taxane alone. CONCLUSION: Off-label use of BEV for newly diagnosed OC was rare (< 10%), but doubled following presentation of phase II and III data at international meetings. Both clinical (ascites, metastatic disease, and age) and nonclinical (specialty and region) factors were associated with BEV use, and its use was accompanied by a six-fold increase in the cost of one cycle of treatment.

Quality of Life and Adverse Events: Prognostic Relationships in Long-Term Ovarian Cancer Survival.

BACKGROUND: There is a critical need to identify patient characteristics associated with long-term ovarian cancer survival. METHODS: Quality of life (QOL), measured by the Functional Assessment of Cancer Therapy-Ovarian-Trial Outcome Index (FACT-O-TOI), including physical, functional, and ovarian-specific subscales, was compared between long-term survivors (LTS) (8+ years) and short-term survivors (STS) (<5 years) of GOG 218 at baseline; before cycles 4, 7, 13, 21; and 6 months post-treatment using linear and longitudinal mixed models adjusted for covariates. Adverse events (AEs) were compared between survivor groups at each assessment using generalized linear models. All P values are 2-sided. RESULTS: QOL differed statistically significantly between STS (N = 1115) and LTS (N = 260) (P < .001). Baseline FACT-O-TOI and FACT-O-TOI change were independently associated with long-term survival (odds ratio = 1.05, 95% confidence interval = 1.03 to 1.06 and odds ratio = 1.06, 95% confidence interval = 1.05 to 1.07, respectively). A 7-point increase in baseline QOL was associated with a 38.0% increase in probability of LTS, and a 9-point increase in QOL change was associated with a 67.0% increase in odds for LTS. QOL decreased statistically significantly with increasing AE quartiles (cycle 4 quartiles: 0-5 vs 6-8 vs 9-11 vs ≥12 AEs, P = .01; cycle 21 quartiles: 0-2 vs 3 vs 4-5 vs ≥6 AEs, P = .001). Further, LTS reported statistically significantly better QOL compared with STS (P = .03 and P = .01, cycles 4 and 21, respectively), with similar findings across higher AE grades. CONCLUSIONS: Baseline and longitudinal QOL change scores distinguished LTS vs STS and are robust prognosticators for long-term survival. Results have trial design and supportive care implications, providing meaningful prognostic value in this understudied population.

Post hoc analyses of GOG 9923: Does BRCA status affect toxicities?: An NRG oncology study.

OBJECTIVE: To evaluate how women with epithelial ovarian cancer (EOC), dichotomized by BRCA status, tolerate intravenous (IV) or intraperitoneal (IP) chemotherapy given with veliparib and bevacizumab (bev) on a GOG phase I study (GOG 9923, NCT00989651). METHODS: This is an unplanned, post hoc analysis of an IRB approved, multi-institutional, prospective study (GOG 9923). Clinical characteristics and toxicity data based on BRCA status were evaluated and descriptive statistics were used to summarize baseline patient characteristics and toxicities. The Kaplan Meier method was used to generate survival estimates. RESULTS: Four hundred twenty-four patients were evaluable. Patients were treated with IV carboplatin, paclitaxel, and bev every 21 days (regimen 1), weekly IV paclitaxel with carboplatin and bev (regimen 2) or IV paclitaxel and bev with IP cisplatin (regimen 3). Bev was continued as maintenance in all arms. Within each of these regimens, veliparib was given either twice daily for the entirety of each cycle (continuous) or on days -2 to 5 (intermittent). Ten percent of patients treated on regimen 1, 12% on regimen 2, and 19.8% on regimen 3 had BRCA-associated tumors. Patients with BRCA-associated tumors, when compared to wild type, experienced similar rates of anemia, febrile neutropenia (, abdominal pain, colonic perforation, nausea, vomiting, and peripheral sensory neuropathy. Median progression free survival (PFS) was not significantly different between BRCA-associated and wild type cancers (HR 0.96, CI 0.65-1.42), though this study's primary aim was not to evaluate outcomes. CONCLUSIONS: Germline BRCA mutations positively affect chemosensitivity in EOC, but whether differences in toxicities among BRCA-associated and BRCA wild type tumors existed was previously not reported. In this population with newly diagnosed ovarian cancer no differences in reported toxicity between the two groups was observed.

Ovarian Cancer, Version 2.2020, NCCN Clinical Practice Guidelines in Oncology.

Epithelial ovarian cancer is the leading cause of death from gynecologic cancer in the United States and is the country's fifth most common cause of cancer mortality in women. A major challenge in treating ovarian cancer is that most patients have advanced disease at initial diagnosis. These NCCN Guidelines discuss cancers originating in the ovary, fallopian tube, or peritoneum, as these are all managed in a similar manner. Most of the recommendations are based on data from patients with the most common subtypes─high-grade serous and grade 2/3 endometrioid. The NCCN Guidelines also include recommendations specifically for patients with less common ovarian cancers, which in the guidelines include the following: carcinosarcoma, clear cell carcinoma, mucinous carcinoma, low-grade serous, grade 1 endometrioid, borderline epithelial, malignant sex cord-stromal, and malignant germ cell tumors. This manuscript focuses on certain aspects of primary treatment, including primary surgery, adjuvant therapy, and maintenance therapy options (including PARP inhibitors) after completion of first-line chemotherapy.

A phase I study of intravenous or intraperitoneal platinum based chemotherapy in combination with veliparib and bevacizumab in newly diagnosed ovarian, primary peritoneal and fallopian tube cancer.

BACKGROUND: Improvements in disease free survival for epithelial ovarian, peritoneal or fallopian tube cancer (EOC) will only come with improved primary therapy. Incorporation of poly-ADP-ribose inhibitors (PARPi) in the frontline setting may represent one strategy. This study sought to determine the maximum tolerated and feasible doses of the PARPi veliparib in combination with chemotherapy for EOC. METHODS: A phase I, 3 + 3 dose escalation evaluated dose-limiting toxicities (DLTs) in cycles 1-2. Once <2/6 patients experienced a DLT, that dose level expanded to evaluate feasibility over 4 cycles. This study opened 10/2009 and closed 8/2016. Eligible patients had untreated, stage II-IV EOC. Veliparib was added either continuous (day 1-21) or intermittent (day - 2 to 5) during 6 cycles of chemotherapy. Three chemotherapy backbones were evaluated (2 intravenous (q3week and weekly) and 1 intraperitoneal (IP)) all inclusive of bevacizumab with and as maintenance to 22 cycles. FINDINGS: Dose evaluations for 424 treated patients were available. Regimen 1 (q3 week), continuous (Reg1c) the maximum tolerated dose (MTD) was 250 mg veliparib BID and feasible dose was 150 mg BID. For regimen 1, intermittent (Reg1i) the MTD and feasible dose were 400 and 250 mg BID. For Reg2c (weekly paclitaxel) the MTD and feasible dose were 150 mg BID. For Reg2i the MTD and feasible dose were 250 and 150 mg BID. For Reg3c (IP) the MTD and feasible dose were 150 mg BID and for Reg3i (IP), the MTD and feasible dose were 400 mg and 300 mg BID. INTERPRETATION: The feasible dose for Reg1c, 2c, 2i and 3c was 150 mg po BID. For Reg1i and 3i the dose was pushed to 250 and 300 mg po BID respectively. There is no apparent difference in efficacy between continuous and intermittent dosing indicating that the higher doses achieved in intermittent dosing may not be needed. (NCT00989651).

The association between HIV infection and cervical cancer presentation and survival in Uganda.

Our objective was to determine how HIV infection impacts cervical cancer stage at presentation and overall survival (OS) among Ugandan women. This was a prospective study of 149 women diagnosed with cervical cancer from 2013 to 2015 at the Uganda Cancer Institute. Poisson regression models were fit to calculate prevalence ratios (PR) for the association between HIV infection and late stage at cancer diagnosis. The association between HIV infection and OS after cervical cancer diagnosis was evaluated using Cox proportional hazards models. The cohort included 53 HIV-positive and 96 HIV-negative participants. Median age at diagnosis was 44 years for HIV-positive and 54 years for HIV-negative participants. Seventy-seven percent of HIV-positive participants received antiretroviral therapy. Median baseline CD4 count was 373 cells/mm3 for HIV-positive participants versus 926 cells/mm3 for HIV-negative participants. Thirty-two percent of HIV-positive participants were diagnosed with late stage cervical cancer (III-IV) versus 39% of HIV-negative participants. No association was found between late stage at cancer diagnosis and HIV infection (PR adjusted for age, parity and transport cost 1.0, 95%CI 0.6-1.8). Most women presenting for care received cancer treatment, though almost half who received radiotherapy did not complete treatment. The median OS was 13.7 months for HIV-positive participants and 24.3 months for HIV-negative participants. After adjusting for age and stage, HIV infection was weakly associated with OS (HR 1.3, 95%CI 0.8-2.2). In Uganda, cervical cancer is often incompletely treated and survival remains poor. HIV infection was not associated with cervical cancer stage at diagnosis, but may be weakly associated with shorter survival.

Postoperative narcotic use in patients with ovarian cancer on an Enhanced Recovery After Surgery (ERAS) pathway.

OBJECTIVES: To determine the impact of an ERAS pathway on post-discharge narcotic use for patients with ovarian cancer undergoing open surgery. METHODS: This was a retrospective cohort study of women who underwent open ovarian cancer surgeries in 2014 prior to ERAS ("pre-ERAS") and in 2016/2018 after ERAS was instituted ("ERAS"). Patients taking chronic narcotics were excluded. A statewide prescription monitoring program was used to identify narcotic prescriptions filled in the three months after surgery. Quantity of narcotic medication is referenced in morphine milligram equivalents (MME). RESULTS: 42 pre-ERAS and 94 ERAS patients were included. The groups were similar in age, BMI, diabetes, tobacco use, mean number of prior abdominal/pelvic surgeries, and advanced stage disease. ERAS patients had a shorter hospital stay (6.7 days pre-ERAS vs 4.2 days ERAS, p = 0.003), used less narcotic in the 24 h prior to discharge (74.0 MME pre-ERAS vs 25.8 MME ERAS, p = 0.002), and filled prescriptions at time of discharge for less narcotic (519.9 MME pre-ERAS vs 339.7 MME ERAS, p = 0.011). After hospital discharge, ERAS patients filled fewer additional prescriptions (52.4% pre-ERAS, vs 29.4% ERAS, p = 0.012). In total, ERAS patients filled prescriptions for 55% fewer narcotics in the three months after surgery than the pre-ERAS group (1101.4 MME pre-ERAS vs 492.1 MME ERAS, p < 0.001). CONCLUSIONS: Institution of an ERAS protocol appears to decrease the narcotic needs of patients in the three months after ovarian cancer surgery.

Intraperitoneal ports placed at the time of bowel resection for treatment of ovarian cancer: Complications and surgical outcomes.

OBJECTIVES: To determine if intraperitoneal (IP) ports placed concurrently with bowel resection during surgical treatment of ovarian cancer is associated with more complications than those ports placed without concurrent bowel resection. METHODS: The medical records of all patients who had an IP port placed at our institution between 2005 and 2016 were reviewed. Two groups were analyzed: IP ports placed with bowel resection (IP-BR) and those without (IP). RESULTS: Of 306 patient charts reviewed, 31% had a surgery with IP port placement and concurrent bowel resection (IP-BR). Demographics were similar except for mean BMI (25.6 IP-BR vs 27.4 IP, p = 0.007). More IP-BR patients had stage IIIC disease (83.3% IP-BR vs 56.9% IP, p ≤0.01). Patients were cytoreduced to R0 in 48.7% IP-BR vs 56.4% IP (p = 0.253). For adjuvant treatment, IV chemotherapy was administered before IP chemotherapy in 90.4% IP-BR (median 2 cycles), and 50.3% IP, (median 2 cycles, p < 0.01). Ultimately 80.2% IP-BR (median 4 cycles) and 77.8% IP (median 5 cycles) received IP chemotherapy (p = 0.65). Rates of total IP port complications were similar (19.2% IP-BR vs 23.2% IP, p = 0.397), including IP port infections (0% IP-BR vs 0.7% IP, p = 0.5). Eleven percent of IP-BR patients had a bowel complication (e.g. obstruction or perforation) while IP port was in situ vs 2.7% IP (p = 0.01). Only 2.7% IP-BR and 6% IP discontinued IP chemotherapy due to IP port complication (p = 0.3). CONCLUSIONS: Patients who have IP ports placed concurrently with a bowel resection do not appear to have more complications, nor lower rates of IP chemotherapy administration.

NCCN Guidelines Insights: Ovarian Cancer, Version 1.2019.

Epithelial ovarian cancer is the leading cause of death from gynecologic cancer in the United States, with less than half of patients living >5 years from diagnosis. A major challenge in treating ovarian cancer is that most patients have advanced disease at initial diagnosis. The best outcomes are observed in patients whose primary treatment includes complete resection of all visible disease plus combination platinum-based chemotherapy. Research efforts are focused on primary neoadjuvant treatments that may improve resectability, as well as systemic therapies providing improved long-term survival. These NCCN Guidelines Insights focus on recent updates to neoadjuvant chemotherapy recommendations, including the addition of hyperthermic intraperitoneal chemotherapy, and the role of PARP inhibitors and bevacizumab as maintenance therapy options in select patients who have completed primary chemotherapy.
