Quantifying the Expanding Landscape of Clinical Actionability for Patients with Cancer. Cancer Discov 2024; 14:49-65. [PMID: 37849038 PMCID: PMC10784742 DOI: 10.1158/2159-8290.cd-23-0467] [Citation(s) in RCA: 15] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2023] [Revised: 08/18/2023] [Accepted: 10/02/2023] [Indexed: 10/19/2023]
Abstract
There is a continuing debate about the proportion of cancer patients that benefit from precision oncology, attributable in part to conflicting views as to which molecular alterations are clinically actionable. To quantify the expansion of clinical actionability since 2017, we annotated 47,271 solid tumors sequenced with the MSK-IMPACT clinical assay using two temporally distinct versions of the OncoKB knowledge base deployed 5 years apart. Between 2017 and 2022, we observed an increase from 8.9% to 31.6% in the fraction of tumors harboring a standard care (level 1 or 2) predictive biomarker of therapy response and an almost halving of tumors carrying nonactionable drivers (44.2% to 22.8%). In tumors with limited or no clinical actionability, TP53 (43.2%), KRAS (19.2%), and CDKN2A (12.2%) were the most frequently altered genes. SIGNIFICANCE Although clear progress has been made in expanding the availability of precision oncology-based treatment paradigms, our results suggest a continued unmet need for innovative therapeutic strategies, particularly for cancers with currently undruggable oncogenic drivers.

Phase I Study of a Multivalent WT1 Peptide Vaccine (Galinpepimut-S) in Combination with Nivolumab in Patients with WT1-Expressing Ovarian Cancer in Second or Third Remission. Cancers (Basel) 2023; 15:1458. [PMID: 36900251 PMCID: PMC10001251 DOI: 10.3390/cancers15051458] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Revised: 02/19/2023] [Accepted: 02/22/2023] [Indexed: 03/03/2023] Open
Abstract
We examined the safety and immunogenicity of sequential administration of a tetravalent, non-HLA (human leukocyte antigen) restricted, heteroclitic Wilms' Tumor 1 (WT1) peptide vaccine (galinpepimut-S) with anti-PD-1 (programmed cell death protein 1) nivolumab. This open-label, non-randomized phase I study enrolled patients with WT1-expressing ovarian cancer in second or third remission from June 2016 to July 2017. Therapy included six (every two weeks) subcutaneous inoculations of galinpepimut-S vaccine adjuvanted with Montanide, low-dose subcutaneous sargramostim at the injection site, with intravenous nivolumab over 12 weeks, and up to six additional doses until disease progression or toxicity. One-year progression-free survival (PFS) was correlated to T-cell responses and WT1-specific immunoglobulin (Ig)G levels. Eleven patients were enrolled; seven experienced a grade 1 adverse event, and one experienced a grade ≥3 adverse event considered a dose-limiting toxicity. Ten (91%) of eleven patients had T-cell responses to WT1 peptides. Seven (88%) of eight evaluable patients had IgG against WT1 antigen and full-length protein. In evaluable patients who received >2 treatments of galinpepimut-S and nivolumab, the 1-year PFS rate was 70%. Coadministration of galinpepimut-S and nivolumab demonstrated a tolerable toxicity profile and induced immune responses, as indicated by immunophenotyping and WT1-specific IgG production. Exploratory analysis for efficacy yielded a promising 1-year PFS rate.

Long-term outcomes of patients with recurrent ovarian cancer treated with a polyvalent vaccine with bevacizumab combination. Cancer Immunol Immunother 2023; 72:183-191. [PMID: 35779095 PMCID: PMC10123530 DOI: 10.1007/s00262-022-03225-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2022] [Accepted: 05/17/2022] [Indexed: 01/07/2023]
Abstract
BACKGROUND To characterize the safety, immunogenicity, and outcomes of patients with high-grade serous ovarian cancer (HGSOC) in second or greater remission treated with a polyvalent antigen-KLH plus OPT-821 vaccine construct and bevacizumab. METHODS Patients with recurrent HGSOC were treated with the vaccine plus bevacizumab at our institution from 01/05/2011 to 03/20/2012. Follow-up continued until 03/2021. Blood/urine samples were collected. "Responders" had an immunogenic response to ≥ 3 antigens; "non-responders" to ≤ 2 antigens. RESULTS Twenty-one patients were treated on study. One developed a dose-limiting toxicity (grade 4 fever). Two (10%) experienced bevacizumab-related grade 3 hypertension. Thirteen (68%) and 16 (84%) of 19 responded to ≥ 3 and ≥ 2 antigens, respectively (Globo-H, GM2, TF cluster Tn, MUC-1). Four of 21 patients were alive > 5 years post-treatment. Responders and non-responders had a median PFS of 4.9 months (95% CI: 2.8-8.1) and 5.0 months (95% CI: 0.7-cannot estimate), respectively; median OS was 30.7 months (95% CI: 16.9-52.0) and 34.2 months (95% CI: 12.8-cannot estimate), respectively. On two-timepoint analysis (baseline, week 17), increased IL-8 exhibited improved PFS (HR as 10-unit increase, 0.43; p = 0.04); increased PDGF exhibited worse OS (HR as 10-unit increase, 1.01; p = 0.02). CONCLUSIONS This is the longest follow-up of vaccine administration with bevacizumab in patients with ovarian cancer. The vaccine was well tolerated with bevacizumab. Response was not associated with improved survival. On two-timepoint analysis, increased IL-8 was associated with significant improvement in PFS; increased PDGF with significantly worse OS. For all timepoint measurements, cytokine levels were not significantly associated with survival. TRIAL REGISTRATION NCT01223235.

Small cell neuroendocrine carcinoma of the cervix: Analysis of prognostic factors and patterns of metastasis. Gynecol Oncol Rep 2022; 43:101058. [PMID: 35967833 PMCID: PMC9365998 DOI: 10.1016/j.gore.2022.101058] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 07/28/2022] [Accepted: 07/31/2022] [Indexed: 11/30/2022] Open
Abstract
A two-tier system (limited- or extensive-stage) has been used for small cell neuroendocrine carcinomas of the cervix. Concordance probability estimates found that the 2018 FIGO staging system predicted outcome better than the two-tier system. 38% of patients had metastases at initial diagnosis, and an additional 38% at subsequent recurrence. 38 patients (60%) had brain imaging: 1 (3%) had brain metastasis at diagnosis and 8 (21%) at subsequent recurrence. Providers should have a low threshold for brain imaging in patients with advanced disease or neurologic symptoms.
Objectives To describe characteristics and outcomes of patients with small cell neuroendocrine carcinoma of the cervix (SCNCC) and determine the staging system most predictive of outcome—the two-tier (limited-stage [LS] vs. extensive-stage [ES]) or International Federation of Gynecology and Obstetrics (FIGO) staging system. Methods Patients with SCNCC evaluated at our institution from 1/1/1990–6/30/2021 were included. Medical records were reviewed for variables of interest. Appropriate statistical tests were performed to determine associations. Survival curves were created using the Kaplan-Meier method. Concordance probability estimates (CPEs) were calculated to evaluate the prediction probability of the staging systems. Results Of 63 patients, 41 had LS and 22 ES SCNCC. Patients with ES disease were significantly older than those with LS disease (median, 54 and 37 years, respectively; p < 0.001). Smoking status, race, and history of HPV were not associated with stage or outcomes. Forty-eight patients had metastatic disease (24 [50%] at initial diagnosis). The most common first sites of metastasis were lung (n = 20/48, 42%), lymph nodes (n = 19/48, 40%), and liver (n = 13/48, 27%). Nine patients had brain metastasis (8 symptomatic at recurrence; 1 asymptomatic at initial diagnosis). Both staging systems were associated with progression-free and overall survival. Adjusted CPE found the FIGO staging system was more predictive of outcomes than the two-tier staging system. Conclusions Providers should have a low threshold to obtain brain imaging for patients with SCNCC, especially in the presence of visceral metastases. FIGO staging should be used to classify SCNCC. Further research is necessary to understand prognostic factors of this rare disease.

Phase II study of enzalutamide in androgen receptor positive, recurrent, high- and low-grade serous ovarian cancer. Gynecol Oncol 2022; 164:12-17. [PMID: 34763937 PMCID: PMC9449573 DOI: 10.1016/j.ygyno.2021.10.087] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Revised: 10/19/2021] [Accepted: 10/26/2021] [Indexed: 01/03/2023]
Abstract
OBJECTIVES We sought to determine the safety and efficacy of the oral androgen receptor antagonist enzalutamide in patients with previously treated, recurrent, AR-positive (AR+) ovarian cancer. METHODS This was a single-institution phase II study of patients with AR+ ovarian cancer with measurable disease with 1-3 prior lines of chemotherapy; patients were screened for enrollment from 11/2013-7/2018. Following consent, archival tissue was evaluated for AR+. Enrolled patients received daily enzalutamide 160 mg until progression of disease or treatment discontinuation. Adverse events were graded by CTCAE v4.0. Co-primary endpoints were 6-month progression-free survival (PFS6) and overall response rate (ORR) by RECIST 1.1 criteria. RESULTS During the study period, 160 patients were screened and 59 (45 high-grade serous [HGS] and 14 low-grade serous [LGS]) consented to treatment on study. There was 1 confirmed and 1 unconfirmed partial response. The ORR was 1.7% (90% CI: 0.2-100%). The overall PFS6 rate (as binary) was 22% (90% CI: 15.1-100%). The 6-month PFS rate (as time to event) was 19.8% for HGS patients (90% CI: 12.7-100%) and 38.5% (90% CI: 21.7%-100%) for LGS patients. Grade 3 toxicities occurred in 6 patients (one toxicity (Grade 3 rash) was considered a dose-limiting toxicity). One patient died of cardiac arrest after 42 days on treatment of a cardiac arrest not attributed to study drug. CONCLUSIONS The study met its primary endpoint, with a PFS6 rate of 22% (n = 13); however, the overall response rate was low. Enzalutamide was well tolerated and may be a potential treatment option in select patients.

OncoTree: A Cancer Classification System for Precision Oncology. JCO Clin Cancer Inform 2021; 5:221-230. [PMID: 33625877 PMCID: PMC8240791 DOI: 10.1200/cci.20.00108] [Citation(s) in RCA: 32] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Revised: 10/26/2020] [Accepted: 12/21/2020] [Indexed: 11/20/2022] Open
Abstract
PURPOSE Cancer classification is foundational for patient care and oncology research. Systems such as International Classification of Diseases for Oncology (ICD-O), Systematized Nomenclature of Medicine Clinical Terms (SNOMED-CT), and National Cancer Institute Thesaurus (NCIt) provide large sets of cancer classification terminologies but they lack a dynamic modernized cancer classification platform that addresses the fast-evolving needs in clinical reporting of genomic sequencing results and associated oncology research. METHODS To meet these needs, we have developed OncoTree, an open-source cancer classification system. It is maintained by a cross-institutional committee of oncologists, pathologists, scientists, and engineers, accessible via an open-source Web user interface and an application programming interface. RESULTS OncoTree currently includes 868 tumor types across 32 organ sites. OncoTree has been adopted as the tumor classification system for American Association for Cancer Research (AACR) Project Genomics Evidence Neoplasia Information Exchange (GENIE), a large genomic and clinical data-sharing consortium, and for clinical molecular testing efforts at Memorial Sloan Kettering Cancer Center and Dana-Farber Cancer Institute. It is also used by precision oncology tools such as OncoKB and cBioPortal for Cancer Genomics. CONCLUSION OncoTree is a dynamic and flexible community-driven cancer classification platform encompassing rare and common cancers that provides clinically relevant and appropriately granular cancer classification for clinical decision support systems and oncology research.

A phase 1 dose-escalation study of intraperitoneal cisplatin, intravenous/intraperitoneal paclitaxel, bevacizumab, and olaparib for newly diagnosed ovarian cancer. Gynecol Oncol 2020; 157:214-221. [PMID: 31959492 DOI: 10.1016/j.ygyno.2020.01.018] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2019] [Revised: 01/09/2020] [Accepted: 01/11/2020] [Indexed: 12/21/2022]
Abstract
OBJECTIVE We assessed the safety and maximum tolerated dose (MTD) of the poly ADP-ribose polymerase (PARP) inhibitor olaparib with intravenous (IV)/intraperitoneal (IP) cisplatin/paclitaxel and IV bevacizumab, followed by olaparib and bevacizumab maintenance, in patients with newly diagnosed ovarian cancer who had undergone primary debulking surgery. METHODS Treatment included: (Cycles 1-6) Day 1, IV paclitaxel 135 mg/m2/3 h + (from Cycle 2 onward) bevacizumab 15 mg/kg; Day 2, IP cisplatin 75 mg/m2; Days 2-8, olaparib (50/100/200 mg BID); Day 8, IP paclitaxel 60 mg/m2 of a 21-day cycle. Maintenance (Cycles 7-22) included: olaparib 300 mg BID and bevacizumab 15 mg/kg Day 1. The primary endpoint was MTD of olaparib, chemotherapy, and bevacizumab. RESULTS Seventeen women were treated (Cohort 1 [50 mg olaparib], 8 patients; Cohort 2 [100 mg], 3 patients; and Cohort 3 [200 mg], 6 patients). Median age was 57 years (47-73); 94% had stage III disease; 29% had a germline BRCA mutation. Two of 6 patients in Cohort 3 experienced a dose-limiting toxicity (DLT). Grade 3/4 toxicities included: neutropenia (56%), lymphopenia (31%), anemia (25%), and fatigue (19%). Most patients started (88%, 81%) and completed (75%, 50%) maintenance olaparib and bevacizumab, respectively; 36% of patients on olaparib maintenance required a dose reduction. Median PFS was 33 months (26.2-NA). CONCLUSIONS The MTD of intermittently dosed olaparib with concurrent IV/IP cisplatin/paclitaxel and bevacizumab is 100 mg BID. Non-hematologic toxicities were predominantly low grade. One-third of patients on olaparib maintenance required dose reduction.

Gynecol Oncol 2019; 155:393-399. [PMID: 31653510 DOI: 10.1016/j.ygyno.2019.09.015] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2019] [Revised: 09/13/2019] [Accepted: 09/14/2019] [Indexed: 10/25/2022]
Abstract
OBJECTIVE Early-phase data have demonstrated induction of antibody responses to a polyvalent vaccine conjugate (Globo-H, GM2, MUC1-TN, TF) with adjuvant OPT-821. We sought to determine if this combination decreases the hazard of progression or death compared to OPT-821 alone in patients with ovarian cancer in second/third clinical complete remission following chemotherapy. Secondary and translational objectives were overall survival (OS), safety, and immunogenicity. METHODS From 2010-2013, patients were randomized (1:1) to receive OPT-821±vaccine-KLH conjugate subcutaneously at weeks 1, 2, 3, 7, 11, and then every 12 weeks (total 11). Dose delay or reduction was not permitted. Patients were removed for pre-defined dose-limiting toxicity. RESULTS Of 171 patients randomized, 170 were treated. Most had disease of serous histology (85%), stage 3 disease at diagnosis (77%), and had received 2 prior regimens (68%). 32% received >6 treatment cycles [median 6, each arm (p = 0.33)]. 77% discontinued due to progression, 4% due to toxicity, and 1 due to myeloid dysplastic syndrome (MDS). Maximum toxicities included grade 4 MDS and depression/personality change (1 each, unlikely related), as well as grade 3 gastrointestinal disorders and others (n = 21, 4 related). Lesser adverse events were injection site reactions (82%) and fever (11%). Estimated HR for progression-free survival (PFS) of the vaccine + OPT-821 to OPT-821 arm was 0.98 (95% CI: 0.71-1.36). At a median follow-up of 60 months, median OS was 47 and 46 months, respectively. CONCLUSIONS Vaccine + OPT-821 compared to OPT-821 alone was modestly immunogenic and did not prolong PFS or OS. Multi-remission patients are a viable, well-defined population for exploring innovative consolidation and maintenance approaches. TRIAL REGISTRATION NCT00857545.

Abstract
OBJECTIVE Hypersensitivity with repeated exposure to platinum agents is common and can preclude continued treatment, even in patients with disease that remains platinum sensitive. We sought to compare the effects of prophylactic, extended carboplatin infusion versus standard infusion on the rate of carboplatin hypersensitivity reactions (HSRs) in women with recurrent ovarian cancer. METHODS This was a single-institution, randomized, nonblinded trial comparing a graded, 3-hour extended infusion of carboplatin with a standard 30-minute infusion in patients with recurrent ovarian cancer who were enrolled from January 2011 to April 2015. The study was designed to detect a decrease in the HSR rate from 20% (standard infusion) to 5% (extended infusion) assuming a type 1 error of 10% and power of 80% using a 1-sided test. RESULTS Of 146 enrolled patients, 114 were evaluable. Fifteen (13%) had an HSR-11% (6/56) in the extended-infusion and 16% (9/58) in the standard-infusion groups (P = 0.582). Planned treatment completion was achieved in 50 (89%) of 56 patients and 49 (84%) of 58 patients, respectively. Of 25 patients who received single-agent carboplatin, 8 (32%) had an HSR (53% of all patients who had an HSR [8/15]). Of 23 patients who received carboplatin with gemcitabine, 4 (17%) had an HSR (27% of all patients who had an HSR [4/15]). Of 8 patients who received carboplatin with paclitaxel, 3 (38%) had an HSR (20% of all patients who had an HSR [3/15]). There were no HSRs with pegylated liposomal doxorubicin, the most commonly given concurrent chemotherapy (46% of all patients). CONCLUSIONS A prophylactic, extended carboplatin infusion was not associated with a decreased HSR rate. The overall low HSR rate suggests that premedication may help reduce HSRs.

Abstract
Tumor molecular profiling is a fundamental component of precision oncology, enabling the identification of genomic alterations in genes and pathways that can be targeted therapeutically. The existence of recurrent targetable alterations across distinct histologically defined tumor types, coupled with an expanding portfolio of molecularly targeted therapies, demands flexible and comprehensive approaches to profile clinically relevant genes across the full spectrum of cancers. We established a large-scale, prospective clinical sequencing initiative using a comprehensive assay, MSK-IMPACT, through which we have compiled tumor and matched normal sequence data from a unique cohort of more than 10,000 patients with advanced cancer and available pathological and clinical annotations. Using these data, we identified clinically relevant somatic mutations, novel noncoding alterations, and mutational signatures that were shared by common and rare tumor types. Patients were enrolled on genomically matched clinical trials at a rate of 11%. To enable discovery of novel biomarkers and deeper investigation into rare alterations and tumor types, all results are publicly accessible.

Progression-free and overall survival of a modified outpatient regimen of primary intravenous/intraperitoneal paclitaxel and intraperitoneal cisplatin in ovarian, fallopian tube, and primary peritoneal cancer. Gynecol Oncol 2012; 125:621-4. [PMID: 22446622 DOI: 10.1016/j.ygyno.2012.03.027] [Citation(s) in RCA: 39] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2012] [Revised: 03/14/2012] [Accepted: 03/14/2012] [Indexed: 01/03/2023]
Abstract
OBJECTIVE GOG study 172 demonstrated improved progression-free (PFS) and overall (OS) survival for patients with stage III optimally debulked ovarian and peritoneal carcinoma treated with IV/IP paclitaxel and IP cisplatin compared to standard IV therapy. The inpatient administration, toxicity profile, and limited completion rate have been blamed for the lack of acceptance and widespread use of this regimen. We sought to evaluate the PFS, OS, toxicity, and completion rate of a modified outpatient IP regimen. METHODS Using a prospectively maintained database, we evaluated the outcomes of patients who underwent primary optimal cytoreduction for stage III ovarian, tubal, or peritoneal carcinoma followed by IV/IP chemotherapy from 1/05-3/09. Our modified regimen was as follows: IV paclitaxel (135 mg/m(2)) over 3h on day 1, IP cisplatin (75 mg/m(2)) on day 2, and IP paclitaxel (60 mg/m(2)) on day 8, given every 21 days for 6 cycles. RESULTS We identified 102 patients who initiated the modified IV/IP regimen and completed chemotherapy. The median follow-up was 43 months. The median age at diagnosis was 57 years (range, 23-76). Primary disease site was: ovary, 77 (75%); fallopian tube, 13 (13%); peritoneum, 12 (12%). FIGO stage was: IIIA, 8 (8%); IIIB, 4 (4%); IIIC, 90 (88%). Residual disease after cytoreduction was: none, 58 (57%); ≤ 1 cm, 44 (43%). The most frequent grade 3/4 toxicities were: neutropenia, 12 (12%); gastrointestinal, 8 (8%); neurologic, 6 (6%). Eighty-two (80%) of 102 patients completed 4 or more cycles of IV/IP therapy; 56 (55%) completed all 6 cycles. The median PFS and OS were 29 and 67 months, respectively. CONCLUSIONS By modifying the GOG 172 treatment regimen, convenience, toxicity, and tolerability appear improved, with survival outcomes similar to those of GOG 172. This modified IV/IP regimen warrants further study.

Abstract
PURPOSE Intraperitoneal (IP) cisplatin and intravenous (IV) or IP paclitaxel constitute a standard therapy for optimally debulked ovarian cancer. Bevacizumab prolongs progression-free survival (PFS) when included in first-line IV chemotherapy. In this study, the safety and feasibility of adding bevacizumab to a first-line IP regimen were assessed. PATIENTS AND METHODS Treatment was as follows: paclitaxel 135 mg/m(2) IV over 3 hours day 1, cisplatin 75 mg/m(2) IP day 2, and paclitaxel 60 mg/m(2) IP day 8. Bevacizumab 15 mg/kg IV was given after paclitaxel on day 1 beginning in cycle 2. After six cycles of chemotherapy, bevacizumab was given every 3 weeks for 17 additional treatments. The primary end point was safety and tolerability determined by whether 60% of patients completed six cycles of IV/IP chemotherapy. RESULTS Of 41 treated patients, 30 (73%) received six cycles of IV/IP chemotherapy and 35 (85%) received at least four cycles. Three (27%) of those who discontinued chemotherapy did so because of complications related to bevacizumab (hypertension, n = 2; perforation, n = 1). Grades 3 to 4 toxicities included neutropenia (34%), vasovagal syncope (10%), hypertension (7%), nausea/vomiting (7%), hypomagnesemia (7%), and abdominal pain (7%). There were three grade 3 small bowel obstructions (7%) during cycles 3, 9, and 15. One patient died following rectosigmoid anastomotic dehiscence during cycle 4. Estimated median PFS is 28.6 months (95% CI, 19.1 to 38.9 months). Three patients (7%) had IP port malfunction. CONCLUSION The addition of bevacizumab to this IP regimen is feasible; however, bevacizumab may increase the risk of bowel obstruction/perforation. The observed median PFS is similar to that seen with IP/IV chemotherapy alone.

The prophylactic conversion to an extended infusion schedule and use of premedication to prevent hypersensitivity reactions in ovarian cancer patients during carboplatin retreatment. Gynecol Oncol 2009; 116:326-31. [PMID: 19944454 DOI: 10.1016/j.ygyno.2009.10.070] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2009] [Revised: 10/20/2009] [Accepted: 10/21/2009] [Indexed: 10/20/2022]
Abstract
OBJECTIVE Repeated exposure to carboplatin can lead to hypersensitivity reactions during retreatment with carboplatin. This may prevent its further use in platinum-sensitive ovarian cancer patients. At our institution, an increasing proportion of patients are prophylactically converted to an extended schedule of infusion after 8 cycles of carboplatin. We sought to determine whether an incrementally increasing, extended 3-hour infusion of carboplatin with appropriate premedication was associated with a lower rate of hypersensitivity reactions compared to the standard 30-minute schedule in sequentially treated patients. METHODS We performed a retrospective electronic medical record review of patients with recurrent ovarian cancer retreated with carboplatin at our institution from January 1998 to December 2008. RESULTS Seven hundred and seventy-seven patients with relapsed ovarian, fallopian tube, or primary peritoneal cancer were retreated with carboplatin and met study inclusion criteria. Of these, 117 (17%) developed hypersensitivity reactions during second-line or greater carboplatin-based treatment for recurrent disease. Only 6 (3.4%) of the 174 patients who received the extended schedule developed hypersensitivity reactions (0% grade 4; 50% grade 3) compared to 111 (21%) of 533 patients in the standard schedule group (13% grade 4; 77% grade 3). The first hypersensitivity episode occurred after a median of 16 platinum (carboplatin and cisplatin) treatments in the extended group compared to 9 in the standard group. Using the Fisher exact test, there was an association with a reduced incidence of hypersensitivity reactions with the extended infusion schedule (P<0.001). CONCLUSION Our data suggest appropriate premedication and prophylactic conversion to an extended infusion during carboplatin retreatment may reduce hypersensitivity reactions.

Exploratory analysis of serum CA-125 response to surgery and the risk of relapse in patients with FIGO stage IIIC ovarian cancer. Gynecol Oncol 2009; 115:209-14. [PMID: 19664812 DOI: 10.1016/j.ygyno.2009.06.038] [Citation(s) in RCA: 28] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2009] [Revised: 06/18/2009] [Accepted: 06/26/2009] [Indexed: 11/26/2022]
Abstract
OBJECTIVE To analyze whether serum CA-125 response to cytoreductive surgery before initiation of postoperative chemotherapy is associated with progression-free survival (PFS) in patients with stage IIIC ovarian carcinoma. METHODS We included consecutive patients with paired pre- and postoperative CA-125 measurements who underwent primary cytoreductive surgery followed by platinum-based chemotherapy between 1989 and 2006. The association of perioperative CA-125 changes with PFS was investigated using a time-to-event analysis. A Cox proportional hazards model was fit using clinical, surgical, and postoperative treatment characteristics. RESULTS The study included 307 evaluable patients. Overall, perioperative serum CA-125 changes were associated with PFS. The risk of disease progression increased incrementally as the magnitude of the serum CA-125 response to surgery decreased (trend test; P=0.003). This association was pronounced in optimally but not observed in suboptimally debulked patients. After optimal cytoreduction, a perioperative increase of serum CA-125 levels was strongly associated with an increased risk of relapse compared to patients who experienced a decline of 80% or more (adjusted HR=4.2; 95% CI: 2.04-8.66; P=0.0001). CONCLUSION Perioperative serum CA-125 changes are strongly associated with the risk of relapse in patients with optimally resected stage IIIC disease. The results of this study provide meaningful support for additional translational research correlating perioperative serum CA-125 responses of patients with molecular tumor characteristics. This may be useful for patient counseling and risk stratification during subsequent clinical trials as well as for the development of novel prognostic models.

Abstract
BACKGROUND The aim was to determine the long-term outcome for patients with FIGO stage IV epithelial ovarian carcinoma (EOC) treated with intraperitoneal (IP) chemotherapy after second-look assessment. METHODS By using data from a retrospective cohort of 433 patients who received IP therapy after second-look assessment after primary surgery and initial systemic therapy for EOC between 1984 and 1998 at our institution, all FIGO stage IIIC and IV patients were identified. Standard statistical methods were used. RESULTS Overall, 297 patients met study criteria (246 stage IIIC; 51 stage IV). The median survival for patients with stage IV disease was 34 months compared with 42 months for patients with stage IIIC disease (P=.02). The only significant predictor of overall survival in patients with stage IV disease was the presence of gross residual disease at initiation of IP therapy (P=.027). When comparing stage IV patients with and without pleural effusions to all stage IIIC patients, there was a significant trend toward improved survival in the patients with pleural effusions only compared with other stage IV patients (P=.01). CONCLUSIONS Prolonged overall survival was observed in patients with no gross residual disease at the time of IP chemotherapy initiation. When compared with similarly treated stage IIIC patients, stage IV patients with malignant pleural effusions appear to have a better outcome than those with other sites of metastasis. Future prospective trials should evaluate the use of IP therapy for patients with stage IV EOC by virtue of malignant pleural effusions only who responded to initial systemic therapy.

Abstract
OBJECTIVE The objective of the study was to compare chemotherapy response and survival of patients with advanced primary peritoneal carcinoma (PPC) vs those with epithelial ovarian carcinoma (EOC). STUDY DESIGN From 1998 to 2004, 43 PPC patients were identified and matched to 129 patients with International Federation of Gynecology and Obstetrics stage IIIC-IV EOC by criteria abstracted from medical records. Primary endpoints were chemotherapy response, platinum resistance, progression-free survival (PFS), and overall survival (OS). RESULTS All patients received primary platinum-taxane chemotherapy. There was no significant difference in achieving a clinical complete response. PPC patients were more likely to be platinum resistant at 6 months and had significantly impaired PFS and OS. After multivariate analysis, PPC was independently associated with a worse prognosis for both survival endpoints. CONCLUSION PPC was associated with a similar initial response but a higher rate of platinum resistance and shorter PFS and OS. Consideration of these results may be useful for patient counseling, trial stratification, and molecular comparisons.

Abstract
PURPOSE To characterize the safety and immunogenicity of a heptavalent antigen-keyhole limpet hemocyanin (KLH) plus QS21 vaccine construct in patients with epithelial ovarian, fallopian tube, or peritoneal cancer in second or greater complete clinical remission. EXPERIMENTAL DESIGN Eleven patients in this pilot trial received a heptavalent vaccine s.c. containing GM2 (10 microg), Globo-H (10 microg), Lewis Y (10 microg), Tn(c) (3 microg), STn(c) (3 microg), TF(c) (3 microg), and Tn-MUC1 (3 microg) individually conjugated to KLH and mixed with adjuvant QS21(100 microg). Vaccinations were administered at weeks 1, 2, 3, 7, and 15. Periodic blood and urine samples were obtained to monitor safety (complete blood count, comprehensive panel, amylase, thyroid-stimulating hormone, and urinalysis) and antibody production (ELISA, fluorescence-activated cell sorting, and complement-dependent cytotoxicity). RESULTS Eleven patients were included in the safety analysis; 9 of 11 patients remained on study for at least 2 weeks past fourth vaccination and were included in the immunologic analysis (two withdrew, disease progression). The vaccine was well tolerated. Self-limited and mild fatigue (maximum grade 2 in two patients), fever, myalgia, and localized injection site reactions were most frequent. No clinically relevant hematologic abnormalities were noted. No clinical or laboratory evidence of autoimmunity was seen. Serologic responses by ELISA were largely IgM against each antigen with the exception of Tn-MUC1 where both IgM and IgG responses were induced. Antibody responses were generally undetectable before immunization. After immunization, median IgM titers were as follows: Tn-MUC1, 1:640 (IgG 1:80); Tn, 1:160; TF, 1:640; Globo-H, 1:40; and STn, 1:80. Only one response was seen against Lewis Y; two were against GM2. Eight of nine patients developed responses against at least three antigens. Antibody titers peaked at weeks 4 to 8 in all patients. Fluorescence-activated cell sorting and complement-dependent cytotoxicity analysis showed substantially increased reactivity against MCF7 cells in seven of nine patients, with some increase seen in all patients. CONCLUSIONS This heptavalent-KLH conjugate plus QS21 vaccine safely induced antibody responses against five of seven antigens. Investigation in an adequately powered efficacy trial is warranted.

Abstract
OBJECTIVE We report the outcome of seven patients treated for recurrent ovarian cancer with cisplatin after an allergic reaction to carboplatin. One case is presented in which a heavily pretreated patient suffered a severe anaphylactic reaction, which was refractory to standard resuscitative measures and resulted in her death. METHODS Six further patients who received cisplatin after documentation of an allergic reaction to carboplatin (CBDCA) for the treatment of recurrent epithelial ovarian cancer between 1993 and 2000 were identified from the MSKCC database. Electronic medical records were reviewed for relevant treatment and outcome data. RESULTS Five of six of these patients were successfully treated without further allergic reactions. One patient with platinum-refractory disease had an allergic reaction to carboplatin and subsequently to cisplatin. CONCLUSION Few patients with a carboplatin allergy are subsequently treated with cisplatin at our center. One patient suffered a serious hypersensitivity reaction following retreatment and died. Based on this limited experience, cross allergy can exist although the true incidence is not known. Routine retreatment of carboplatin-allergic patients with cisplatin in the relapsed setting cannot be recommended without careful consideration of potential risks and benefits.

Abstract
As the initial step in developing carbohydrate-based vaccines for the treatment of ovarian cancer patients in an adjuvant setting, 25 patients were immunized with a Lewis(y) pentasaccharide (Le(y))-keyhole limpet hemocyanin (KLH)-conjugate vaccine together with the immunological adjuvant QS-21. Four different doses of the vaccine, containing 3, 10, 30, and 60 microg of carbohydrate were administered s.c. at 0, 1, 2, 3, 7, and 19 weeks to groups of 6 patients. Sera taken from the patients at regular intervals were assayed by ELISA for reactivity with naturally occurring forms of Le(y) (Le(y)-ceramide and Le(y) mucin) and by flow cytometry and a complement-dependent cytoxicity assay for reactivity with Le(y)-expressing tumor cells. The majority of the patients (16/24) produced anti-Le(y) antibodies as assessed by ELISA, and a proportion of these had strong anti-tumor cell reactivity as assessed by flow cytometry and complement-dependent cytotoxicity. One serum, analyzed in detail, was shown to react with glycolipids but not with glycoproteins or mucins expressed by ovarian cancer cell line OVCAR-3. The vaccine was well tolerated and no gastrointestinal, hematologic, renal, or hepatic toxicity related to the vaccine was observed. On the basis of this study, Le(y)-KLH should be a suitable component for a polyvalent vaccine under consideration for the therapy of epithelial cancers.
