e17523 Background: Receipt of surgery and adjuvant chemotherapy greatly impact survival outcomes for ovarian cancer, the deadliest gynecologic malignancy with a high recurrence/progression rate. Most patients receive first-line, platinum-based chemotherapy. Platinum-based chemotherapy causes severe side effects, including nephrotoxicity and myelosuppression. Evidence for other chemotherapeutic agents is lacking and options are limited for women who cannot tolerate first-line chemotherapy. We aimed to determine the prevalence of premature first-line chemotherapy discontinuation and to detail reasons for discontinuation. Methods: We used the population-based cohort, Patterns of Ovarian Cancer Care and Survival in the Midwestern Region of the United States—a CDC Investigation, comprised of women diagnosed with histologically confirmed, stage IB-IV ovarian cancer in 2010-2012 in the Midwestern United States (i.e., Iowa, Kansas and Missouri) between the ages of 18 and 89 years. We limited the cohort to patients who received cancer-directed surgery and initiated adjuvant chemotherapy. Chemotherapy lines, completion, and reasons for discontinuation were abstracted from patient medical records by cancer registrars using standardized protocols. Results: Nineteen percent (N= 107/559) of ovarian cancer patients who initiated adjuvant chemotherapy did not complete first-line treatment. Reasons for chemotherapy discontinuation included toxicity or other kinds of intolerance (39%), poor quality of life or comorbid conditions (19%) or exhibited no response (17%) (Table). No significant differences were observed between gynecologic oncologists and non-gynecologic oncologist chemotherapy providers (p=0.109). Conclusions: One in 5 women who initiated did not complete first-line chemotherapy. Reasons were varied and suggested that lack of tolerance is not the only factor in discontinuation. Lack of response and the presence of comorbid conditions are considerations that can be taken into account during decision-making processes for treatment. More clinical research into additional chemotherapy options that may be useful in these patients is necessary.[Table: see text]

Abstract Background The aim of this study was to evaluate the efficacy and safety of first-line chemotherapy with re-introduction of oxaliplatin (OX) more than 6 months after adjuvant chemotherapy including OX. Methods Stage II/III colon cancer patients with neuropathies of grade ≤ 1 who relapsed more than 6 months after adjuvant chemotherapy including OX were considered eligible. Eligible patients were treated with 5-fluorouracil, l-leucovorin and OX plus molecularly targeted agents or capecitabine and OX plus bevacizumab (BV) or S-1 and OX plus BV. The primary endpoint was the progression-free survival (PFS), and the secondary endpoints were the overall survival (OS), response rate (RR) and toxicity. Results A total of 50 patients were enrolled between September 2013 and May 2019. Twelve patients received 5-fluorouracil, l-leucovorin and OX (FOLFOX) plus BV, 21 patients received capecitabine and OX plus BV, 10 patients received S-1 and OX plus BV and 7 patients received FOLFOX plus cetuximab or panitumumab. The median PFS was 11.5 months (95% confidence interval [CI] 8.3–16.0), the median OS was 45.4 months (95% CI 37.4–NA), and the RR was 56.0% (95% CI 42.3–68.8). Adverse events of grade ≥ 3 that occurred in ≥ 5% of cases were neutropenia in 6 patients (12%), peripheral sensory neuropathy in 5 patients (10%), diarrhea in 4 patients (8%), hypertension in 4 patients (8%), anorexia in 3 patients (6%) and allergic reactions in 3 patients (6%). Conclusions First-line chemotherapy with re-introduction of OX more than 6 months after adjuvant chemotherapy including OX can be used safely with expected efficacy for relapsed colon cancer patients.

e16557 Background: EpCAM is a tumor associated antigen which is frequently expressed in ovarian cancer. Recently, an autoantibody (AAB) against EpCAM has been identified in ovarian cancer patients. Autoantibodies are immunogene factors and might be of prognostic importance. We showed that disseminated tumor cells (DTC) in bone marrow carry the EpCAM antigen on their surface and correlate with poorer progression free survival (PFS). Here, we evaluated whether EpCAM-AABs have an impact on clinical parameters or the presence of DTC in ovarian cancer patients. Methods: EpCAM-AABs were determined in sera of 28 healthy voluntary age matched females and 62 patients with primary epithelial ovarian cancer before and after platinum-based chemotherapy using a recombinant EpCAM-epitope for antibody- detection by ELISA technique. Mean follow up time was 13 months. DTC in BM were detected by immunocytochemistry applying the pan cytokeratin antibody A45-B/B3. All samples exceeding the mean antibody titer of healthy controls plus 2 standard deviations were considered positive. Results: The antibody titer of healthy controls was 0.061 + 0.015. Using a cut-off value of 0.091, we found 9/62 (15%) ovarian cancer patients to be positive for EpCAM-AABs after first-line treatment. Interestingly, no positive AAB-titers were seen before therapy. Using the paired T-Test, we noted a significant posttherapeutic increase of AABs (CI 0.95, p < 0.0001). Analysis of PFS, FIGO stage, resection status, grading, age, sensitivity to platinum based chemotherapy and DTC did not reveal significant associations with positive EpCAM-AAB titers. Conclusions: The clinical course of ovarian cancer patients and the prevalence of DTC were not altered by EpCAM-AABs. Interestingly, we observed an increase of antibody-levels after first-line treatment. For further validation, we intend to extend our patient collective. In future, it might also be interesting to investigate the impact of AABs on response to targeted therapies against EpCAM. No significant financial relationships to disclose.

Precise Relationship

Retrospective studies have shown an improved prognosis, higher response rates to platinum-containing regimens, and longer treatment-free intervals between relapses in patients with BRCA 1 and BRCA 2 ( BRCA1/2)–mutated ovarian cancer (BMOC) compared with patients who are not carriers of this mutation. These features of BMOC are attributed to homologous-recombination repair (HR) deficiency in the absence of BRCA1/2 function, which results in an impaired ability of tumor cells to repair platinum-induced double-strand breaks (DSBs), thereby conferring increased chemosensitivity and increased sensitivity to poly(ADP-ribose) polymerase (PARP) enzyme inhibition and other DNA-damaging chemotherapeutic agents such as pegylated liposomal doxorubicin (PLD). Therefore, the chemotherapeutic approach for patients with BMOC should focus on treatment with platinum-based chemotherapy at first-line and recurrent-disease settings and measures to increase the platinum-free interval following early platinum-resistant relapse (i.e., progression-free survival of less than 6 months from last platinum-based chemotherapy) by using nonplatinum cytotoxic agents, with the aim of reintroducing platinum again at a later date. The role of first-line intraperitoneal platinum-based therapy in the specific context of BMOC also merits further analysis. Other than platinum, alternative DNA-damaging agents (including PLD and trabectedin) also may have a therapeutic role in patients with recurrent BMOC. The recent approval of olaparib for clinical use in Europe and the United States will also affect chemotherapeutic strategies for these patients. Further work to clarify the precise relationship between BRCA1/2 mutation genotype and clinical phenotype is crucial to delineating the optimal therapeutic choices in the future for patients with BMOC.
