Brief Summary

Antiangiogenic therapies like bevacizumab, have notably improved cancer treatment, including for gynecological cancers, by inhibiting the vascular endothelial growth factor and thus limiting tumor growth. In treating advanced ovarian cancer, bevacizumab has been shown to extend progression-free survival by four months, though it also induces or worsens hypertension in 2 to 19% of patients by affecting vascular nitric oxide production or by capillary rarefaction. This hypertension may result in severe cardiovascular events, necessitating the use of antihypertensive drugs like calcium channel blockers and RAAS inhibitors (angiotensin converting enzyme - ACE - inhibitors mainly), despite some concerns about their effects on VEGF secretion and CA125 levels. Clinical guidelines vary, with some favoring ACE inhibitors while others recommend calcium channel blockers, underlining the need for comparative studies on these drugs' oncological and cardiovascular impacts. To address these issues, this study utilizes an emulated trial approach, leveraging comprehensive data from the French National Health Data System to compare the efficacy of these antihypertensive classes in reducing relapse and improving survival in ovarian cancer patients treated with bevacizumab. The investigators will emulate a target clinical trial to compare the impact of antihypertensive treatments on outcomes of patients with bevacizumab-associated hypertension by ACE inhibitors (arm A) versus calcium channel blockers (CCBs, arm B) on the risk of ovarian cancer withdrawal after surgery.

Outcome Measures

Primary Outcomes (1)

  • Progression-free survival for ovarian cancer

    The per-protocol average treatment effect (ATE) will be estimated by the one-, two-, and three-year differences in PFS probability, and three-year restricted mean survival time (RMST) differences in the IPC-weighted population. The main outcome will be at three-year. Covariate adjustment : Covariates included in the inverse probability weighting are: (i) age at trial inclusion, (ii) number and type of comorbidities, (iii) economic deprivation level, (iv) number of general practitioner consultations the year before, (v) number of gynecologist consultation the year before, (vi) number of cardiology consultation at inclusion, (vii) number of nephrology consultation at inclusion, (viii) FIGO stage, (ix) surgical strategy, (x) hospital annual ovarian cancer volume, and (xi) hospital academic status

    PFS is defined as the time, from ovarian cancer first surgery to death, progression or recurrence, whichever occurres first, assessed up to 7 years

Secondary Outcomes (4)

  • Overall survival

    OS is defined as the time, from ovarian cancer first surgery to death from any cause, assessed up to 7 years

  • Major Cardiovascular Event (MACE) - narrow definition

    Time from ovarian cancer first surgery to the time of MACE-narrow, assessed up to 7 years

  • Major Cardiovascular Event (MACE) - broad definition

    Time from ovarian cancer first surgery to the time of MACE-broad, assessed up to 7 years

  • Time to treatment failure (TTF)

    Time from bevacizumab initiation to the first antihypertensive treatment switch or change to bitherapy, assessed up to 7 years

Study Arms (5)

Main analysis - antihypertensive therapy with bevacizumab (ACEi or CCBs)

Adjuvant/maintenance bevacizumab after ovarian cancer debulking surgery with antihypertensive therapy monotherapy. Any patients with bevacizumab treated with monotherapy ACEi (arm A) or CCB (arm B) up to 6 months following debulking surgery

Drug: arm A - angiotensin converting enzyme inhibitors (ACEi)Drug: arm B - calcium channel blockers (CCBs)

Complementary group - arm C1 - bevacizumab without antihypertensive therapy

Patients treated with bevacizumab without initiation of antihypertensive treatment within 6 months following debulking surgery

Complementary group - arm C2 - standard chemotherapy alone

Patients who were only treated by standard chemotherapy within 6 months following debulking surgery without bevacizumab

Complementarity analysis - 1st-line CCB vs ACEi vs ARBs

Adjuvant/maintenance bevacizumab after ovarian cancer debulking surgery with antihypertensive therapy monotherapy. Any patients with bevacizumab treated with Renin Angiotensin Aldosterone System (RAAS) inhibitor drug among ACEi (arm A) versus angiotensin receptor blocker ARB (arm R) versus CCB (arm B)

Drug: arm A - angiotensin converting enzyme inhibitors (ACEi)Drug: arm B - calcium channel blockers (CCBs)Drug: arm R - angiotensin receptor blockers ARB

Sensitivity analysis

Sensitivity analysis S1 - Impact of Antihypertensive Treatment Switching. The investigators will utilize time-varying inverse probability of censoring weights (IPCW). The first step of the IPCW method consists in censoring patients who interrupt their initially assigned treatment. The second step of the IPCW method is thus to use IPCW with baseline covariates and time-dependent covariates linked to the treatment switching. (i) Number of cardiology consultations, (ii) Number of nephrology consultations or proteinuria, (iii) Number of cardiovascular events related to hypertension (MACE broad) Sensitivity analysis S2 - Exclusion of patients with isolated proteinuria or elevated proteinuria: The investigators will reproduce the main analysis, excluding patients with signs of isolated proteinuria or elevated proteinuria.

Drug: arm A - angiotensin converting enzyme inhibitors (ACEi)Drug: arm B - calcium channel blockers (CCBs)

ACEi will be defined as any drugs from the Anatomical Therapeutic Classification C09AA with an indication for hypertension, including but not limited to: captopril, enalapril, lisinopril, perindopril, ramipril, quinapril

Complementarity analysis - 1st-line CCB vs ACEi vs ARBsMain analysis - antihypertensive therapy with bevacizumab (ACEi or CCBs)Sensitivity analysis
