Early treatment modifications improve chemotherapy adherence in ovarian cancer patients ≥70 years

A multicenter retrospective study to assess feasibility, safety and efficacy of first-line carboplatin-paclitaxel versus carboplatin monotherapy in a frail, elderly epithelial ovarian cancer population

OBJECTIVE

Underrepresentation of elderly ovarian cancer patients in clinical trials has led to lack of clarity regarding optimal first-line chemotherapy in this cohort. The Elderly Women with Ovarian Cancer (EWOC)-1 trial demonstrated that 3-weekly carboplatin (3wC) resulted in worse survival and feasibility compared with standard 3-weekly carboplatin-paclitaxel (3wCP) in frail, elderly ovarian cancer patients. Our retrospective study compares feasibility, safety, and efficacy of first-line 3wCP and 3wC in a frail ovarian cancer cohort.

METHODS

Clinical data were retrospectively analyzed for newly-diagnosed, International Federation of Gynecology and Obstetrics (FIGO) stage III/IV, ≥70-year-old epithelial ovarian cancer patients, treated by clinician choice with 3wC or 3wCP at two London cancer centers over a 2 year period. Charlson Comorbidity Index (CCI) and Eastern Cooperative Oncology Group (ECOG) performance status provided surrogate markers of frailty. Common Terminology Criteria for Adverse Events v5.0 graded toxicity.

RESULTS

A total of 107 patients were treated with 3wC (n=30) and 3wCP (n=77). Age, performance status, and CCI were significantly different between cohorts, with 3wC patients older (84 vs 75 years, p<0.001), with more comorbidities (median CCI 4 vs 3, p<0.001) and worse performance status (47% vs 17% PS ≥2, p=0.015). Surgical outcomes differed significantly between cohorts, with 20 (67%) 3wC patients not undergoing surgery, compared with 22 (29%) 3wCP patients (p<0.001). Median follow-up was 45.8 months (IQR 38.7-56.3 months). While we observed improved progression-free (HR 0.55, 95% CI 0.33 to 0.90, p=0.017) and overall survival (HR 0.44, 95% CI 0.27 to 0.73, p=0.001, log-rank test) in a univariate cox proportional hazards comparison between 3wCP and 3wC, this was not significant on multivariate analysis. Completion of six planned chemotherapy cycles was achieved by the majority, with similar discontinuation rates between groups (13% 3wC vs 8% 3wCP, p>0.05). Overall grade ≥3 hematological toxicity rates were similar between regimens (33% 3wC vs 44% 3wCP, p=0.37) with grade ≥3 neutropenia (p=0.019) and grade ≥3 thrombocytopenia (p=0.006) more common with 3wCP and 3wC, respectively. No treatment-related deaths occurred.

CONCLUSION

Our data demonstrates that standard 3wCP is a well-tolerated, feasible first-line treatment for frail, elderly ovarian cancer patients. Improved survival with 3wCP was not significant when corrected for established clinical prognostic factors.

Retrospective multicenter study of elderly patients with platinum-sensitive relapsed ovarian cancer treated with trabectedin and pegylated liposomal doxorubicin (pld) in a real-world setting: a geico study

BACKGROUND

Trabectedin in combination with pegylated liposomal doxorubicin (PLD) is approved for the treatment of patients with platinum-sensitive relapsed ovarian cancer. Nevertheless, there is currently limited information regarding this treatment in elderly patients with ovarian cancer in a real-world setting.

METHODS

This observational and multicentric study retrospectively evaluated trabectedin plus PLD in a real-world setting treatment of elderly patients diagnosed with platinum-sensitive relapsed ovarian cancer, treated according to the Summary of Product Characteristics (SmPC) from 15 GEICO-associated hospitals. Patients ≥ 70 years old at the time of treatment initiation and platinum-free intervals ≥ 6 months were considered eligible.

RESULTS

Forty-three patients with a median age of 74.0 years were treated between January 1st, 2015, and December 31st, 2019 in 15 Spanish centers. Four patients achieved complete response (9.3%), 14 (32.6%) partial response, and 13 (30.2%) stable disease as the best radiological response. In the analysis of biological overall response according to CA125 serum levels (i.e., Rustin criteria), 14 responded to the treatment (32.6%), 11 responded and normalized (25.6%), three patients stabilized (7.0%) and three progressed (7.0%). Median progression-free survival (PFS) and overall survival (OS) in the study population were 7.7 and 19.5 months, respectively. The most common grade 3/4 adverse events were neutropenia (n = 8, 18.7%) and asthenia (n = 5, 11.6%).

CONCLUSIONS

This analysis demonstrated that trabectedin combined with PLD is a feasible and effective treatment in elderly patients with platinum-sensitive relapsed ovarian cancer, showing an acceptable safety profile, which is crucial in the palliative treatment of these patients.

Incidence and predictors for chemotherapy modifications and their impact on the outcome of ovarian cancer patients

PURPOSE

Chemotherapy (CTX) is an important part of the treatment strategy of stage II-IV ovarian cancer. CTX modifications, such as delays, dose reductions or premature terminations might have a negative impact on overall survival (OS) and progression free survival (PFS). The goal of this study was to determine the incidence and predictors of CTX modifications and their influence on survival.

METHODS

An observational retrospective cohort analysis of 192 ovarian cancer patients who were treated at the Department of Obstetrics and Gynaecology, Technical University Munich, Germany, according to international guidelines was performed including from 2009 to 2013. A potential association between patient and disease characteristics and CTX modifications was tested with multivariate logistic regression. OS and PFS were estimated by Kaplan-Meier analysis.

RESULTS

44.8% (86/192) received a modification of CTX. 34 (17.7%) women discontinued CTX prematurely, 17 (8.9%) underwent a dose reduction, 16 (8.3%) experienced a CTX delay and 10 (5.2%) had both a delay and a dose modification. In nine (4.7%) patients, the dose needed to be divided. Leukopenia (p < 0.001) and anaemia (p = 0.003) were significantly more common in patients with CTX modifications. Significant predictors for CTX modifications were a history of thrombosis or embolism (p < 0.001) and residual tumour postoperatively (p = 0.003). Patients with CTX modifications showed a significantly lower OS as well as PFS (p < 0.001), even after adjustment for prognostic factors such as age, body-mass-index, residual tumour, histology, FIGO stage and grading (p = 0.005 for OS and p = 0.001 for PFS).

CONCLUSION

CTX modifications have a negative impact on survival. Significant predictors for such modifications are a history of thrombosis or embolism and the presence of residual postoperative tumour. Further studies are needed to avoid CTX modifications and to improve survival of ovarian cancer patients.

Development and External Validation of a Novel Model for Predicting Postsurgical Recurrence and Overall Survival After Cytoreductive R0 Resection of Epithelial Ovarian Cancer

Purpose

Treatment of epithelial ovarian cancer is evolving towards personalization and precision, which require patient-specific estimates of overall survival (OS) and progression-free survival (PFS).

Patients and Methods

Medical records of 1173 patients who underwent debulking surgery in our center were comprehensively reviewed and randomly allocated into a derivation cohort of 879 patients and an internal validation cohort of 294 patients. Five hundred and seventy-seven patients from the other three cancer centers served as the external validation cohort. A novel nomogram model for PFS and OS was constructed based on independent predictors identified by multivariable Cox regression analysis. The predictive accuracy and discriminative ability of the model were measured using Harrell’s concordance index (C-index) and calibration curve.

Results

The C-index values were 0.82 (95% CI: 0.76–0.88) and 0.84 (95% CI: 0.78–0.90) for the PFS and OS models, respectively, substantially higher than those obtained with the FIGO staging system and most nomograms reported for use in epithelial ovarian cancer. The nomogram score could clearly classify the patients into subgroups with different risks of recurrence or postoperative mortality. The online versions of our nomograms are available at https://eocnomogram.shinyapps.io/eocpfs/ and https://eocnomogram.shinyapps.io/eocos/.

Conclusion

A externally validated nomogram predicting OS and PFS in patients after R0 reduction surgery was established using a propensity score matching model. This nomogram may be useful in estimating individual recurrence risk and guiding personalized surveillance programs for patients after surgery, and it could potentially aid clinical decision-making or stratification for clinical trials.

Long-term quality of life and sexual function of elderly people with endometrial or ovarian cancer

Background

With the growing number of older endometrial cancer (EC) and ovarian cancer (OC) survivors, data on long-term health-related quality of life (HRQoL) became an important issue in the management of older patients. So, the aim of this study was to describe and compare according to age long-term HRQoL, sexual function, and social deprivation of adults with either EC or OC.

Methods

A cross-sectional study was set up using data from the Côte d’Or gynecological cancer registry. A series of questionnaires assessing HRQoL (SF-12), sexual function (FSFI), anxiety/depression (HADS), social support (SSQ6) and deprivation (EPICES) were offered to women with EC or OC diagnosed between 2006 and 2013. HRQoL, sexual function, anxiety/depression, social support and deprivation scores were generated and compared according to age (< 70 years and ≥ 70 years).

Results

A total of 145 women with EC (N = 103) and OC (N = 42) participated in this study. Fifty-six percent and 38% of EC and OC survivors respectively were aged 70 and over. Treatment did not differ according to age either in OC or EC. The deprivation level did not differ between older and younger survivors with OC while older survivors with EC were more precarious. The physical HRQoL was more altered in older EC survivors. This deterioration concerned only physical functioning (MD = 24, p = 0.012) for OC survivors while it concerned physical functioning (MD = 30, p < 0.0001), role physical (MD = 22, p = 0.001) and bodily pain (MD = 21, p = 0.001) for EC survivors. Global health (MD = 11, p = 0.011) and role emotional (MD = 12, p = 0.018) were also deteriorated in elderly EC survivors. Sexual function was deteriorated regardless of age and cancer location with a more pronounced deterioration in elderly EC survivors for desire (p = 0.005), arousal (p = 0.015) and orgasm (p = 0.007). Social support, anxiety and depression were not affected by age regardless of location.

Conclusion

An average 6 years after diagnosis, the impact of cancer on HRQoL is greatest in elderly survivors with either EC or OC.

Interval Debulking Surgery for Advanced Ovarian Cancer in Elderly Patients (≥70 y): Does the Age Matter?

BACKGROUND

Elderly ovarian cancer (OC) patients are more likely to be managed suboptimally, with worse clinical outcomes as a result. Strategies to decrease morbidity are lacking.Methodology: Consecutive patients with advanced stage OC (IIIC-IV) who were managed in our center between January 2016 and July 2018 were retrospectively analyzed. All patients underwent neoadjuvant chemotherapy (NACT) and interval debulking surgery (IDS) according to our institution protocol. We divided patients into two groups: Group 1 (age ≥ 70 years) and Group 2 (age < 70 years). The primary outcome of the study was assessment of peri-operative morbidity amongst two groups.

RESULTS

A total of 153 patients were referred during the study period. 114 patients underwent IDS after NACT (74.5%), 46 in Group 1 and 68 in Group 2. Elderly patients were more likely to receive more than three cycles of NACT prior to IDS compared to younger patients (39% vs. 19%, p = 0.03). Elderly patients were more frequently subjected to Cardiopulmonary Exercise Testing (CPET) as pre-operative assessment (63% vs. 27%, p = 0.002). Optimal/complete resection was achieved in all patients in Group 1 (100%) and in 97% of patients in Group 2. With the exception of higher postoperative cardiac arrhythmias in Group 1 (11% vs. 1%, p = 0.04), no significant differences in 30-day morbidity were observed. No 90-day death in both groups was registered.

CONCLUSION

Older age should not preclude clinicians from offering ultra-radical resection to patients with advanced OC after NACT. In our series, elderly patients received the same treatment with similar outcomes to the younger group. Clinicians should be encouraged to use CPET for patients' selection following NACT.
