Ovarian cancer: lines of therapy

Cancer page →

15 standard-of-care settings across 7 lines and 5 biomarker subgroups. Rows come from the cancer page's standard of care; the grid places each on its line and subgroup.

Screening, prevention and diagnosis

SubgroupSettingApproachProducts and trialsEvidence
All comersPrevention and riskGermline testing for all patients; risk-reducing salpingo-oophorectomy for BRCA carriers (age 35-45); opportunistic salpingectomy at pelvic surgery for average-risk women; oral contraceptives reduce risk. No population screening (UKCTOCS negative).91

Early / localised

SubgroupSettingApproachProducts and trialsEvidence
All comersNewly diagnosed stage I-IIComplete surgical staging; adjuvant carboplatin-paclitaxel for high-grade or stage IC-II disease; observation for low-risk stage IA-IB grade 1-2.81

Locally advanced

SubgroupSettingApproachProducts and trialsEvidence
All comersNewly diagnosed stage III-IV: surgery and chemotherapyPrimary debulking if complete resection is feasible, else 3 cycles neoadjuvant carboplatin-paclitaxel then interval debulking (with HIPEC in stage III, OVHIPEC-1) and 3 more cycles; add bevacizumab for high-risk or residual disease.98

Advanced, first line

SubgroupSettingApproachProducts and trialsEvidence
All comersNewly diagnosedSurgery + platinum-taxane ± bevacizumab ± HIPEC; PARP maintenance by HRD status.87

Maintenance

SubgroupSettingApproachProducts and trialsEvidence
BRCA / HRDFirst-line maintenance, BRCA-mutatedOlaparib 2 years (SOLO-1) or olaparib + bevacizumab (PAOLA-1) or niraparib 3 years (PRIMA).87
BRCA / HRDFirst-line maintenance, HRD-positive BRCA-wild-typeOlaparib + bevacizumab (PAOLA-1, OS benefit) or niraparib (PRIMA, PFS only).98
BRCA / HRDFirst-line maintenance, HRD-negativeBevacizumab continuation if started; niraparib is an option with small PFS benefit and no OS benefit (PRIMA); observation is reasonable.98

Second line

SubgroupSettingApproachProducts and trialsEvidence
All comersPlatinum-sensitive relapsePlatinum doublet + PARP maintenance; secondary cytoreduction in selected cases.
All comersPlatinum-resistantMirvetuximab (FRα-high), relacorilant + nab-paclitaxel, pembrolizumab (PD-L1+), single-agent chemotherapy.98
All comersPlatinum-sensitive relapse (interval >6 months)Secondary cytoreduction if AGO-score positive (DESKTOP III); platinum doublet (carboplatin with PLD, paclitaxel, or gemcitabine) ± bevacizumab; PARP maintenance if PARP-naive and BRCA/HRD-positive.98
All comersPlatinum-resistant relapse, otherRelacorilant + nab-paclitaxel (ROSELLA, approved 2026); single-agent weekly paclitaxel, PLD, or topotecan ± bevacizumab (AURELIA); clinical trials of FRα and CDH6 ADCs.98
FRαPlatinum-resistant relapse, FRα-highMirvetuximab soravtansine (MIRASOL, OS benefit) with ophthalmic prophylaxis.77
PD-L1Platinum-resistant relapse, PD-L1 CPS ≥1Pembrolizumab + weekly paclitaxel ± bevacizumab (KEYNOTE-B96, approved Feb 2026).98

Other settings

SubgroupSettingApproachProducts and trialsEvidence
All comersRare histologiesClear-cell: platinum-based therapy, trials of immunotherapy and ARID1A-directed agents; mucinous: consider GI regimens and HER2 testing; germ-cell: BEP chemotherapy with >90% cure.99
HR-positiveLow-grade serous carcinomaSurgery; endocrine maintenance (letrozole) after chemotherapy or instead of it; at recurrence, avutometinib + defactinib if KRAS-mutated (2025), trametinib, or endocrine therapy.89

Lines and subgroups are parsed from the setting text of each standard-of-care row and can misclassify an unusual phrasing; the row’s own setting is always shown. Guideline chips reflect the NCCN category and ESMO-MCBS grade recorded on the cancer page, checked on its stated date. Not medical advice.
