Second primary cancer after primary peritoneal, epithelial ovarian, and fallopian tubal cancer: a retrospective study.

ABSTRACT:

Background

In this retrospective study, data from patients listed in the Korea Central Cancer Registry during 1993-2014 were analysed, to investigate the incidence and survival of second primary cancers (SPCs) after a diagnosis of primary peritoneal, epithelial ovarian, and fallopian tubal (POFT) cancer.

Methods

The standardised incidence ratio (SIR) and survival outcomes of patients with SPCs among POFT cancer survivors were analysed.

Results

Among 20,738 POFT cancer survivors, 798 (3.84%) developed SPCs, at an average interval of 5.50 years. SPC risk in POFT survivors (SIR, 1.29) was higher compared to the general population. The most high-risk type of SPC was leukaemia (3.07) followed by the lung and bronchus (1.80), colon (1.58), rectum and rectosigmoid junction (1.42), thyroid (1.34), and breast (1.26). In women aged ConclusionsThe overall SPC risk increases in POFT cancer survivors, especially in those

Project description:BACKGROUND:Primary debulking surgery (PDS) and adjuvant chemotherapy is the standard treatment for advanced ovarian, fallopian or primary peritoneal cancer. However, neoadjuvant chemotherapy (NAC) followed by interval debulking surgery (IDS) has been introduced as an alternative, showing similar efficacy and decreased postoperative complications compared with PDS. Although there is still no evidence for whether three or four cycles of NAC used clinically could be adequate, reducing one cycle of NAC is expected to remove more visible tumours and thereby improve prognosis. Thus, we proposed with this study to evaluate the efficacy and safety of reducing one cycle of NAC for advanced ovarian, fallopian or primary peritoneal cancer. METHODS:This study is a prospective, multi-centre, open-label, randomized phase III trial. A total of 298 patients with advanced ovarian, fallopian or primary peritoneal cancer will be recruited and randomly assigned to either three (control group) or two cycles of NAC (experimental group). After the NAC, we will conduct IDS with maximal cytoreduction and then administer the remaining three or four cycles for a total of six cycles of adjuvant chemotherapy. The primary end point is progression-free survival, and the secondary end points are time to tumour progression, overall survival, tumour response after NAC, IDS and adjuvant chemotherapy, radiologic investigation after IDS, tumour response by positron emission tomography-computed tomography after NAC, quality of life, adverse events, success rate of optimal cytoreduction, surgical complexity, postoperative complications and safety of IDS. We will assess these factors at screening, at every cycle of chemotherapy, at IDS, after the completion of chemotherapy, every 3 months for the first 2 years after the planned treatment and every 6 months thereafter for 3 years. DISCUSSION:We hypothesize that reducing one cycle of NAC will contribute to more resection of visible tumours despite 10% reduction of optimal cytoreduction, which could improve survival. Moreover, two cycles of NAC may increase postoperative complications by 5% compared with three cycles, which may be acceptable. TRIAL REGISTRATION:This study has been prospectively registered at ClinicalTrials.gov on Oct. 2nd, 2018 (NCT03693248, URL: https://clinicaltrials.gov/ct2/show/NCT03693248).

Project description:BackgroundBiologically targeted therapies have been postulated as a viable strategy to improve outcomes for women with ovarian cancer. We assessed the safety, tolerance, pharmacokinetics, relevant circulating and image-derived biomarkers, and clinical activity of combination aflibercept and docetaxel in this population.MethodsFor the phase 1 (pharmacokinetic) study, eligible patients had measurable, recurrent or persistent epithelial ovarian, primary peritoneal, or fallopian tube carcinoma with a maximum of two prior chemotherapy regimens. Aflibercept was administered intravenously over three dose levels (2, 4, or 6 mg/kg; one dose every 21 days) to identify the maximum tolerated dose for the phase 2 study. Pharmacokinetics were assessed and dynamic imaging was done during a lead-in phase with single-agent aflibercept (cycle 0) and during combination therapy with intravenous docetaxel (75 mg/m(2)). Eligibility for the phase 2 study was the same as for phase 1. Patients were enrolled in a two-stage design and given aflibercept 6 mg/kg intravenously and docetaxel 75 mg/m(2) intravenously, every 3 weeks. The primary endpoint was objective response rate (ORR) as assessed by Response Evaluation Criteria in Solid Tumors version 1.0. The trial has completed enrolment and all patients are now off study. The trial is registered at ClinicalTrials.gov, number NCT00436501.FindingsFrom the phase 1 study, the recommended phase 2 doses of aflibercept and docetaxel were found to be 6 mg/kg and 75 mg/m(2), respectively. Log-linear pharmacokinetics (for unbound aflibercept) were observed for the three dose levels. No dose-limiting toxicities were noted. 46 evaluable patients were enrolled in the phase 2 trial; 33 were platinum resistant (15 refractory) and 13 were platinum sensitive. The confirmed ORR was 54% (25 of 46; 11 patients had a complete response and 14 had a partial response). Grade 3-4 toxicities observed in more than two patients (5%) were: neutropenia in 37 patients (80%); leucopenia in 25 patients (54%); fatigue in 23 patients (50%); dyspnoea in ten patients (22%); and stomatitis in three patients (7%). Adverse events specifically associated with aflibercept were grade 1-2 hypertension in five patients (11%), and grade 2 proteinuria in one patient (2%).InterpretationCombination aflibercept plus docetaxel can be safely administered at the dose and schedule reported here, and is associated with substantial antitumour activity. These findings suggest that further clinical development of this combination in ovarian cancer is warranted.FundingUS National Cancer Institute, US Department of Defense, Sanofi-Aventis, Gynecologic Cancer Foundation, Marcus Foundation, and the Commonwealth Foundation.
