Under-treatment of elderly patients with ovarian cancer: a population based study

The challenge of ovarian cancer care in the oldest old

INTRODUCTION

Ovarian cancer (OC) is the eighth most common cancer in women, with a poor prognosis, particularly in older women. The aim of this study was to describe an octogenarian population with OC and to examine the differences in net survival (NS) according to age.

MATERIAL AND METHODS

In this retrospective observational population-based study from a gynecological cancer registry, patients aged > 18 years with an identified epithelial ovarian cancer stage IA to IVB diagnosed between 1998 and 2018 were included. Patients with non-available FIGO stage were excluded. Patients were stratified into three age groups: <70, 70-79 and ≥80 years, then by OC stage (FIGO I-II, IIIA-IIIB, IIIC-IV). Sociodemographic and cancer-related variables were compared using univariate test (Khi²). The 5-year NS was calculated using the Pohar-Perme method.

RESULTS

Among the 721 patients included: 462 (64.1 %) were younger than 70 years, 176 (24.4 %) were aged between 70 and 79 years, and 83 (11.85 %) were aged 80 years or older. Patients ≥80 years had a trend for lower rate of serous carcinoma than the other age subgroups. As age increased, patients were less likely to undergo surgery and chemotherapy. While 73 % of women <70 years received a combination of surgery and chemotherapy, the rate was 62 % among women 70-79 years and 27 % among women ≥80 years (p<.0001). When focusing on FIGO IIIC-IV stages, the 5-year NS rate for women <70 years was 45.1 % (95 % CI 39.1-52.0). For women 70-79 years, it was 25.9 % (95 % CI 18.6-36.1), and for those ≥80 years, it was 19.5 % (95 % CI 10.0-38.0) (p<.005).

DISCUSSION

The oldest patients had less optimal treatment and a lower NS compared to patients in their seventies or younger. Frailty should be carefully assessed to optimize care in the oldest patients with OC.

Real-world trends in the use of maintenance therapy in ovarian cancer across the United States from 2017 to 2021

OBJECTIVE

We assessed real-world trends in the use of maintenance therapy [MT] (i.e., polyADP-ribose polymerase inhibitors (PARPi) and/or bevacizumab following platinum-based chemotherapy), among U.S. patients with ovarian cancer.

METHODS

Using Medicare and commercial administrative health claims data from Optum's de-identified Clinformatics® Data Mart Database, we identified patients who had been diagnosed with ovarian cancer between January 1, 2010, and March 31, 2021, and received platinum-based chemotherapy and MT. Multivariable logistic regression and Cox proportional hazards regression were used to evaluate associations between demographic and clinical characteristics and MT use.

RESULTS

Our study included 6339 patients, with a median age of 70 years. The majority were White (70.1 %), Medicare-insured (71.9 %), and were treated in the South (42.5 %). Of the 31.5 % who received MT, 18.1 % received bevacizumab alone, 10.2 % PARPi alone, and 3.3 % both. After adjusting for insurance type, PARPi and bevacizumab use increased significantly from 2017 to 2020. Patients with a high Elixhauser comorbidity index were more likely to receive MT than were patients with a low index [OR (95 % CI): 1.46 (1.28-1.67), p < 0.0001]. PARPi use was significantly associated with treatment in the South [1.42 (1.10-1.83), p = 0.01]. Compared to patients who received neither agents, those who received bevacizumab, alone or in combination with PARPi, had a higher risk of death [HR = 2.02 (95 % CI: 1.70-2.28, p < 0.0001) and 1.66 (1.24-2.23), p = 0.001, respectively].

CONCLUSIONS

The majority of patients with ovarian cancer are not utilizing maintenance therapy after platinum-based chemotherapy. Age, comorbidity status, and geographic region of treatment were associated with MT use. Understanding the factors and real-world outcomes associated with MT use is important to support patients in making value concordant and informed decisions.

Homologous recombination deficiency should be tested for in patients with advanced stage high-grade serous ovarian cancer aged 70 years and over

OBJECTIVE

Due to limited data on homologous recombination deficiency (HRD) in older patients (≥ 70 years) with advanced stage high grade serous ovarian cancer (HGSC), we aimed to determine the rates of HRD at diagnosis in this age group.

METHODS

From the Phase 3 trial VELIA the frequency of HRD and BRCA1/2 pathogenic variants (PVs) was compared between younger (< 70 years) and older participants. HRD and somatic(s) BRCA1/2 pathogenic variants (PVs) were determined at diagnosis using Myriad myChoice® CDx and germline(g) BRCA1/2 PVs using Myriad BRACAnalysis CDx®. HRD was defined if a BRCA PV was present, or the genomic instability score (GIS) met threshold (GIS ≥ 33 & ≥ 42 analyzed).

RESULTS

Of 1140 participants, 21% were ≥ 70 years. In total, 26% (n = 298) had a BRCA1/2 PV and HRD, 29% (n = 329) were HRD/BRCA wild-type, 33% (n = 372) non-HRD, and 12% HR-status unknown (n = 141). HRD rates were higher in younger participants, 59% (n = 476/802), compared to 40% (n = 78/197) of older participants (GIS ≥ 42) [p < 0.001]; similar rates demonstrated with GIS ≥ 33, 66% vs 48% [p < 0.001]. gBRCA PVs observed in 24% younger vs 8% of older participants (p < 0.001); sBRCA in 8% vs 10% (p = 0.2559), and HRD (GIS ≥ 42) not due to gBRCA was 35% vs 31% (p = 0.36).

CONCLUSIONS

HRD frequency was similar in participants aged < 70 and ≥ 70 years (35% vs 31%) when the contribution of gBRCA was excluded; rates of sBRCA PVs were also similar (8% v 10%), thus underscoring the importance of HRD and BRCA testing at diagnosis in older patients with advanced HGSC given the therapeutic implications.

Examining the impact of age on chemotherapy completion in epithelial ovarian, fallopian tube and primary peritoneal cancer: a retrospective cohort study in Thailand

OBJECTIVE

To explore the difference in chemotherapy completion and reasons for discontinuation between older (≥70 years) and younger (<70 years) patients.

DESIGN

Retrospective cohort study.

SETTING

Single tertiary centre in Thailand.

PARTICIPANTS

The patients who received chemotherapy from 1 January 2009 to 30 June 2021 were included and followed up until 30 June 2022. Of the 757 patients with epithelial ovarian, fallopian tube and primary peritoneal cancer (EOC), 108 were in the older group and 649 were in the younger group.

PRIMARY AND SECONDARY OUTCOME MEASURES

The difference in chemotherapy completion, the association between younger and older patients and early discontinuation of chemotherapy.

RESULTS

The proportion of chemotherapy completion was significantly lower in older versus younger patients (84.3% versus 92.6%, p=0.007). Excluding discontinuation due to disease progression, the chemotherapy completion was comparable (93.5 versus 95.7%, p=0.456). Dose reduction and grade 3-4 hematotoxicity occurred more often in the older group. The univariable logistic regression model showed that older age (≥70 years) was significantly associated with early chemotherapy discontinuation (OR 2.39; 95% CI 1.29-4.24). However, after adjusting for potential confounders, age was not significantly associated with early discontinuation (OR 1.20; 95% CI 0.54-2.66). Multiple comorbidities and types of surgery were identified as independent risk factors for chemotherapy discontinuation.

CONCLUSION

The completion of chemotherapy was observed in a majority of older adults with EOC. Age is not the only determinant of chemotherapy completion. Comorbidity and disease status are crucial for determining chemotherapy discontinuation.

Impact of FRAilty screening and Geriatric assessment and INtervention in older patients with epithelial Ovarian Cancer: A multicenter randomized clinical trial protocol (FRAGINOC)

INTRODUCTION

Radical surgery combined with chemotherapy is the only potential curative treatment of patients with advanced epithelial ovarian cancer (EOC). However, 43% of older Danish patients with EOC are not referred to surgery due to frailty, age, or fear of complications. Comprehensive geriatric assessment (CGA) has demonstrated ability to reduce frailty in older patients, but there is a knowledge gap regarding its effect before or during treatment in older adults with EOC. This protocol presents a randomized controlled trial (RCT), which evaluates the effect of CGA-based interventions including individualized physical exercise therapy in older adults with EOC during neoadjuvant chemotherapy (NACT).

MATERIALS AND METHODS

This RCT will include patients aged ≥70 years with primary EOC referred to NACT. Patients will be randomized 1:1 to intervention or standard of care, along with neoadjuvant antineoplastic treatment. Stratification for performance status and center of inclusion will be performed. In the intervention arm, a geriatrician will perform CGA and corresponding geriatric interventions and patients will undergo an individualized home-based exercise program managed by a physiotherapist. All patients will be evaluated with Geriatric-8, modified Geriatric-8, clinical frailty scale, and physical tests at randomization. Predictive values (positive/negative) will be evaluated for CGA detected impairments. The primary endpoint is the proportion of patients referred to interval debulking surgery (IDS). Secondary endpoints include the proportion who complete oncological treatment, improvements in physical tests, quality of life measured by European Organization for Research and Treatment of Cancer-Quality of Life questionnaires at inclusion, after three cycles of chemotherapy, and at end of chemotherapy treatment. Furthermore, the association between results of geriatric screening tests, CGA, and physical tests with complication rate and progression free survival will be examined. The primary outcome will be analyzed with logistic regression in the intention-to-treat population. Power calculations reveal the need to enroll 216 patients.

DISCUSSION

The present study examines whether CGA-based interventions including individualized physical exercise can increase the referral rate for potential curative IDS in older patients with EOC. If successful, this will result in more patients undergoing surgery and completing chemotherapy, preventing complications, and ultimately improving quality of life and survival. The study setup may establish the basis for direct clinical implementation if proven effective.

Epidemiology of cancers among older adults in India: findings from the National Cancer Registry Programme

OBJECTIVE

This study describes the epidemiology, clinical extent of disease at diagnosis and treatment modalities of cancer among older adults (aged 60 years and older) in India.

STUDY DESIGN

Secondary data analysis of the National Cancer Registry Programme, which includes 28 Population-Based Cancer Registries (PBCRs) and 96 Hospital-Based Cancer Registries (HBCRs).

METHODS

PBCR data were used to estimate the incidence in terms of crude rate (CR), age-adjusted incidence rate (AAR), age-specific rate (ASpR) and cumulative risk. Trends in the AAR were calculated with the Annual Percentage Change (APC) using join-point regression. HBCR data were used to describe the clinical extent of the disease at diagnosis and the treatment modalities.

RESULTS

There is a wide heterogeneity across the country for the incidence of cancer and for the leading cancer sites among older adults. Males had a higher incidence rate compared to females in the majority of the registries. Aizawl had the highest AARs among both genders (males: 1388.8; females: 1033.0). Females had the highest ASpR at 65-69 years (482.8), whereas for males it was above 75 years (710.4). Cervical, stomach and oesophageal cancers were on the decline. The incidence of cancer among older adults was estimated to increase by 13.5% in 2025 as compared to 2020.

CONCLUSION

The increasing cancer incidence among older adults in India poses a huge burden on the health system. There is a need to increase their participation in clinical trials, advocating comprehensive geriatric assessment and strengthening geriatric oncology within programs addressing older adult's care to deal with the rising cancer burden on the health system borne by them.

Older age should not be a barrier to testing for somatic variants in homologous recombination DNA repair-related genes in patients with high-grade serous ovarian carcinoma

BACKGROUND

Somatic pathogenic variants (PVs) in homologous recombination DNA repair (HR)-related genes found in high-grade serous ovarian carcinomas (HGSC) are not well-characterised in older patients (≥70 years). This may reflect low testing rates in older patients.

METHODS

Data from 1210 HGSC patients in AACR Project GENIE and 324 patients in an independent dataset INOVATe were analysed. Cases where somatic variants could be distinguished from germline variants were included, and analysis was restricted to those with a somatic TP53 variant, to ensure cases were HGSC.

RESULTS

Of 1210 patients in GENIE, 27% (n = 325) were aged ≥70 years at testing. Patients with somatic-only PVs in BRCA2 were older compared with BRCA1 (median 71 vs 60 years, p = 0.002). Median age for 21 patients with somatic-only PVs in 11 other HR-related genes ranged from 40 to 67 years. In older patients, 7% (n = 22) had somatic BRCA1/2 PVs, and 1% (n = 2) had PVs other HR-related genes; this rate was not significantly different to younger patients (<70 years), 7% (n = 62) BRCA1/2 and 2% (n = 19) other HR-related genes (p = 0.36). The overall frequency of somatic BRCA1/2 PVs was similar in INOVATe (n = 25; 7.7%) and somatic-only BRCA2 PVs were again found in older patients compared with BRCA1 (median age: at testing, 70 vs 63 years; at diagnosis, 68 vs 60 years).

CONCLUSIONS

The overall frequency of somatic-only PVs in HR-related genes was similar in older and younger patients with HGSC, highlighting the importance of somatic testing irrespective of age. Limiting somatic testing by age may exclude patients who could benefit from maintenance poly(ADP-ribose) polymerase (PARP) inhibitors.

Surgical Treatment Outcomes of Gynecologic Cancer in Older Patients: A Retrospective Study

This study aimed to evaluate oncologic characteristics and surgical outcomes in older patients with gynecologic cancers. This retrospective study included patients aged ≥65 years who were diagnosed with gynecologic cancers and underwent surgical treatment between 2005 and 2020. We reviewed the medical records for age at diagnosis, body mass index, American Society of Anesthesiologists score, comorbidities, postoperative complications, cancer stage, histologic type, surgical treatment, postoperative outcome, and survival rate. Data were compared between groups according to the age at the time of diagnosis: <75 years (young-old) and ≥75 years (old-old). In total, 131 patients were identified: 53 (40.5%) with ovarian or primary peritoneal cancer (OC), 44 (33.6%) with endometrial cancer (EC), 30 (22.9%) with cervical cancer, and 4 (3.1%) with leiomyosarcoma. The patients' mean age was 70 (range, 65-83) years; 106 (80.9%) were young-old and 25 (19.1%) were old-old. Postoperative complications occurred in 19 (14.5%) patients. Four patients died within six months after surgery, and three died because of disease progression. There was no difference in the survival rates between the two groups among those with OC and EC. Older patients with gynecologic cancers showed good surgical outcomes and tolerable postoperative complications. Therefore, we can safely offer surgical treatment to older patients.

Comparison of older and younger patients with ovarian cancer: A post hoc study (JGOG3016-A3) of the treatment strength and prognostic outcomes of conventional or dose-dense chemotherapy

AIM

To evaluate changes of treatment strength and its impact on prognosis in older patients with ovarian cancer.

METHODS

We compared relative dose intensity (RDI) as a representative of treatment strength, prognosis, and other features between older (≥65 years) and younger patients (<65 years) retrospectively. Seventy-seven older patients of 301 who received dose-dense-paclitaxel-carboplatin (dTC) and 93 older patients of 304 who received conventional-paclitaxel-carboplatin (cTC) from the Japanese Gynecologic Oncology Group (JGOG) 3016 clinical trial were analyzed.

RESULTS

The RDI of older patients was lower than that of younger patients in cTC (87.4% vs. 90.8%, p = 0.009) but not in dTC (79.0% vs. 81.2%, p = 0.205). In both regimens, older patients had worse overall survival than younger patients: hazard ratio [HR] = 1.80; 95% confidence interval [CI]: 1.25-2.59; p = 0.001 for dTC, and HR = 1.59; 95% CI: 1.15-2.19; p = 0.04 for cTC. However, the RDI was not determined as a prognostic factor statistically. The prognostic factors identified by multivariate analysis for both regimens were clinical stage and residual disease; for dTC were age, performance status, and serum albumin; and for cTC was white blood cell count. There was no difference in neutropenia observed between age groups in either regimen.

CONCLUSIONS

The RDI of older patients varies according to the administered schedule and is not always lower than that of younger patients. Older patients with comparable treatment strength to younger patients in the dTC group did not accomplish the same level of prognosis as younger patients. Other biologic factors attributable to aging may affect prognosis.

Efficacy and safety of olaparib according to age in BRCA1/2-mutated patients with recurrent platinum-sensitive ovarian cancer: Analysis of the phase III SOLO2/ENGOT-Ov21 study

BACKGROUND

Olaparib has significantly improved outcome and patient-centered endpoints in BRCA1/2-mutated patients with recurrent platinum-sensitive ovarian cancer (PSOC). Specific information on efficacy and safety of olaparib for older patients appears of special interest.

METHODS

295 patients from the SOLO2 trial randomly assigned to olaparib or placebo were categorized according to age-cutoff at 65 years. Efficacy, tolerability, and quality of life (QoL) of olaparib relative to placebo within in each age group was analyzed.

RESULTS

Baseline characteristics were similar in patients ≥65 years (N = 62;21.0%) compared to patients <65 years (N = 233;78.9%). No significant difference in the magnitude of progression-free survival (PFS) benefit from olaparib for older patients (N = 40, hazard ratio [HR]_≥65 0.43, 95%-confidence interval [CI] 0.24-0.81) as compared with younger patients (N = 155, HR_<65 0.31 (95%-CI 0.22-0.43) was seen (interaction P = 0.33). The overall survival (OS)benefit seen in younger patients in the olaparib arm was not observed in older patients. Older and younger patients had comparable safety profiles and QoL scores although higher discontinuation rates for toxicity, and higher frequency of AML/MDS were noted in the older subset. TWiST analysis revealed clinically meaningful duration of good QoL on olaparib for both age groups (≥65: 13.5 vs <65: 18.4 months, P = 0.05).

CONCLUSIONS

Results of this large phase III cohort of BRCA1/2-mutated PSOC patients treated with olaparib underline impressive efficacy of olaparib maintenance irrespective of age. Although toxicity and tolerability did not raise significant concerns, some caution, close monitoring, and follow-up needs to be exercised for older patients given higher discontinuation rates, frequency of AML/MDS, and no clear effects on OS.

Overall Survival and Related Factors of Advanced-stage Epithelial Ovarian Cancer Patients Underwent Debulking Surgery in Jakarta, Indonesia: A Single-center Experience

AIM: The worrisome prognosis of advanced-stage epithelial ovarian cancer (EOC) needs a new perspective from developing countries. Thus, we attempted to study the 5-year overall survival (OS) of advanced-stage EOC patients who underwent debulking surgery in an Indonesian tertiary hospital. METHODS: A retrospective study recruited forty-eight subjects between 2013 and 2015. We conducted multiple logistic regression analyses to predict risk factors leading to unwanted disease outcomes. The OS was evaluated through the Kaplan–Meier curve and Log-rank test. Cox proportional hazards regression examined prognostic factors of patients. RESULTS: Prominent characteristics of our patients were middle age (mean: 51.9 ± 8.9 years), obese, with normal menarche onset, multiparous, not using contraception, premenopausal, with serous EOC, and FIGO stage IIIC. The subjects mainly underwent primary debulking surgery (66.8%), with 47.9% of all individuals acquiring optimal results, 77.1% of patients treated had the residual disease (RD), and 52.1% got adjuvant chemotherapy. The risk factor for serous EOC was menopause (odds ratio [OR] = 4.82). The predictors of suboptimal surgery were serous EOC (OR = 8.25) and FIGO stage IV (OR = 11.13). The different OS and median survival were observed exclusively in RD, making it an independent prognostic factor (hazard ratio = 3.50). 5-year A five year OS and median survival for patients with advanced-stage EOC who underwent debulking surgery was 37.5% and 32 months, respectively. Optimal versus suboptimal debulking surgery yielded OS 43.5% versus 32% and median survival of 39 versus 29 months. Both optimal and suboptimal debulking surgery followed with chemotherapy demonstrated an OS 40% lower than those not administered (46.2% and 20%, respectively). The highest 5-year OS was in serous EOC (50%). Meanwhile, the most extended median survival was with mucinous EOC (45 months). CONCLUSION: Chemotherapy following optimal and suboptimal debulking surgery has the best OS among approaches researched in this study. RD is a significant prognostic factor among advanced-stage EOC. Suboptimal surgery outcomes can be predicted by stage and histological subtype.

Cardiotoxicity and Chemotherapy-The Role of Precision Medicine

Cancer and cardiovascular disease are the leading causes of death in the United Kingdom. Many systemic anticancer treatments are associated with short- and long-term cardiotoxicity. With improving cancer survival and an ageing population, identifying those patients at the greatest risk of cardiotoxicity from their cancer treatment is becoming a research priority and has led to a new subspecialty: cardio-oncology. In this concise review article, we discuss cardiotoxicity and systemic anticancer therapy, with a focus on chemotherapy. We also discuss the challenge of identifying those at risk and the role of precision medicine as we strive for a personalised approach to this clinical scenario.

Prevalence of and factors associated with treatment modification at first cycle in older adults with advanced cancer receiving palliative treatment

INTRODUCTION

Treatment toxicities are common in older adults with cancer and consequently, treatment modifications are sometimes considered. We evaluated the prevalence and factors associated with treatment modifications at the first cycle in older patients receiving palliative systemic treatment.

METHODS

Patients (n = 369) from the GAP 70+ Trial (NCT02054741; PI: Mohile) usual care arm were included. Enrolled patients were aged 70+ with advanced cancer and ≥ 1 Geriatric Assessment (GA) domain impairment. Treatment modification was defined as any change from National Comprehensive Cancer Network guidelines or published clinical trials. Baseline variables included: 1) sociodemographic factors; 2) clinical variables; 3) GA domains; and 4) physician beliefs about life expectancy. Bivariate analyses and multivariable cluster-weighted generalized estimating equation model were conducted to assess the association of baseline variables with cycle 1 treatment modifications.

RESULTS

Mean age was 77.2 years (range: 70-94); 62% had lung or gastrointestinal cancers, and 35% had treatment modifications at cycle 1. Increasing age by one year (odds ratio (OR) 1.1, 95% confidence interval [CI] 1.0-1.2), receipt of ≥second line of chemotherapy (OR 1.8, CI 1.1-3.0), functional impairment (OR 1.6, CI 1.1-2.3) and income ≤$50,000 (OR 1.7, CI 1.1-2.4) were independently associated with a higher likelihood of cycle 1 treatment modification.

CONCLUSION

Treatment modifications occurred in 35% of older adults with advanced cancer at cycle 1. Increasing age, receipt of ≥second line of chemotherapy, functional impairment, and lower income were independently associated with treatment modifications. These findings emphasize the need for evidence-based regimens in older adults with cancer and GA impairments.

Patients 80 + have similar medication initiation rates to those aged 50-79 in Ontario FLS

Among individuals presenting to an Ontario FLS, we compared bone active medication initiation rates of patients 80 years and older with those 50-79 years old. After accounting for fracture risk status, there was no statistically significant difference in medication initiation rates between the two age groups INTRODUCTION: A Fracture Liaison Service (FLS) offers post-fracture services to individuals over the age of 50 years and could potentially address age inequities in pharmacotherapy often observed for older adults. Among individuals presenting to an Ontario FLS and classified as being at high risk for future fracture, our objective was to compare bone active medication initiation rates of patients 80 years and older with those 50-79 years old.

METHODS

In 39 FLS fracture clinics across Ontario, Canada, fracture prevention coordinators identified, assessed, and facilitated the referral of eligible patients for bone densitometry, fracture risk assessment, and implementation of pharmacotherapy in patients classified as high risk for future fracture. Variables assessed at baseline included age, sex, marital status, living location, fracture location, history of previous fracture, parent's history of hip fracture, history of falls, and fracture risk status. At 6 months, bone active medication initiation was assessed in patients classified as high risk for future fracture. The Chi-square test of independence was used to compare medication initiation rates between patients 80 + and those 50-79 years old.

RESULTS

Our sample size consisted of 808 patients aged 50-79 years and 346 aged 80 + years. After accounting for fracture risk status, there was no statistically significant difference in medication initiation rates of patients 50-79 and 80 + years old (76.9% versus 73.7%, p = 0.251).

CONCLUSION

A systematic approach to identifying patients at high risk for future fracture and tailoring treatment recommendations to these patients appeared to eliminate differences in treatment initiation rates based on older age.

Association Between 5-Item Modified Frailty Index and Short-term Outcomes in Complex Head and Neck Surgery

OBJECTIVES

To evaluate the impact of preoperative frailty on short-term outcomes following complex head and neck surgeries (HNSs).

STUDY DESIGN

Cross-sectional database analysis.

SETTING

American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database.

METHODS

The 2005 to 2017 ACS-NSQIP was queried for patients undergoing complex HNS. Five-item modified frailty index (mFI) was calculated based on functional status and history of diabetes, chronic obstructive pulmonary disease, congestive heart failure, and chronic hypertension.

RESULTS

A total of 2786 patients (73.1% male) with a mean age of 62.0 ± 11.6 years were included. Compared to nonfrail patients (41.2%), patients with mFI ≥1 (58.8%) had shorter length of operation (P = .021), longer length of stay (LOS) (P < .001), and higher rates of 30-day reoperation (P = .009), medical complications (P < .001), discharge to nonhome facility (DNHF) (P < .001), and mortality (P = .047). These parameters remained statistically significant when compared across all individual mFI scores (all P < .05). After adjusting for age, sex, race, body mass index, smoking, and American Society of Anesthesiologists score via multivariate logistic regression, patients with mFI ≥1 were significantly more likely to undergo reoperation (odds ratio [OR], 1.39), surgical complications (OR, 1.19), medical complications (OR, 1.55), prolonged LOS (OR, 1.29), and DNHF (OR, 1.56) (all P < .05). Multivariate logistic regression also demonstrated that after adjusting for confounders, compared to patients with mFI = 1, patients with mFI = 2-5 (18.7%) were more likely to undergo shorter operations (OR, 0.74), have medical (OR, 1.46) or any complications (OR, 1.27), and have DNHF (OR, 1.62) (all P < .05).

CONCLUSION

The 5-point mFI can independently predict short-term surgical outcomes following complex HNS. This simple and reliable metric can potentially lead to improved preoperative counseling and postoperative planning for complex HNS patients.

Short-term outcomes in older patients with peritoneal malignancy treated with cytoreductive surgery and HIPEC: Experience with 245 patients from a national centre

BACKGROUND

Cytoreductive Surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) is increasingly accepted as the optimal management of selected patients with peritoneal malignancy. There is limited published evidence on outcomes in older patients treated by this complex therapeutic strategy.

METHODS

A retrospective review of a prospective database of all patients who underwent CRS with HIPEC in a single institution over seven years. A comparative analysis of outcomes in patients under 65 undergoing CRS and HIPEC with patients ≥65 years was performed. The key endpoints were morbidity, mortality, reintervention rate and length of stay in the high dependency/intensive care (HDU/ICU) units.

RESULTS

Overall, 245 patients underwent CRS and HIPEC during the study period, with 76/245 (31%) ≥65 years at the time of intervention. Tumour burden measured by the peritoneal carcinomatosis index (PCI) score was a median of 11 for both groups. Median length of hospital stay in the ≥65-year-old group was 14.5 days versus 13 days in the <65-year-old group (∗p = 0.01). Patients aged ≥65-years spent a median of one more day in the critical care unit ∗(p = 0.001). Significant morbidity (Clavien-Dindo ≥ Grade IIIa) was higher in the ≥65-year than the <65-year group (18.4% versus 11.2%). There were no perioperative deaths in the ≥65-year group.

CONCLUSION

This study demonstrates higher perioperative major morbidity in ≥65-year group, but with low mortality in patients undergoing CRS/HIPEC for disseminated intraperitoneal malignancy. This increased morbidity does not translate into higher rates of re-interventions and highlights the importance of optimal patient selection.

Exploring Older Women's Attitudes to and Experience of Treatment for Advanced Ovarian Cancer: A Qualitative Phenomenological Study

Simple Summary

Older women with ovarian cancer often receive less anti-cancer treatment than younger women despite evidence showing they may benefit from similar levels of treatment. Little is known, however, about older women’s preferences toward chemotherapy and treatment experience. We aimed to understand the lived experience of older women with ovarian cancer undergoing chemotherapy though interviews and focus groups. Participants expressed a strong desire to undergo full treatment to improve survival for themselves and for their families. Women did not see their age as a reason to have less intensive treatment. Despite feeling overwhelmed with information and daily tasks due to fatigue, participants did not want cancer to interfere with their daily lives. Women felt distressed by logistical issues with transportation and communication between healthcare providers; however, they still felt positive about their care experience and desire for treatment. Older women may benefit from additional help to support effective communication around treatment preferences.

Abstract

Older women with ovarian cancer more often receive less intensive treatment and early discontinuation compared to younger women. There is little understanding of older women’s treatment experience and whether this contributes to declining intensive treatment. We aimed to explore the lived experience of older patients with advanced ovarian cancer undergoing chemotherapy, their treatment preferences and treatment burden. We conducted a phenomenological qualitative study with 15 women who had completed at least three cycles of first-line chemotherapy for advanced epithelial ovarian cancer, aged 65 years or older at the first cycle, at one tertiary cancer centre. We conducted interviews and focus groups and analysed the transcripts using inductive thematic analysis. Women reported a strong preference for active treatment despite treatment burden and toxicities. Participants undertook treatment to lengthen their lives for themselves and their families. Participants did not see age as a barrier to treatment. Patients expressed determination not to let cancer interfere with daily life. Women felt overwhelmed with information and struggled with daily tasks due to fatigue. Logistical issues, such as transportation and ineffective communication between healthcare providers, caused substantial distress. Despite these logistical burdens and toxicities, participants were positive about their care experience and desire for anticancer treatment. Older women may benefit from additional support to facilitate effective communication during the early stages of treatment.

Management of the Elderly Patients with High-Grade Serous Ovarian Cancer in the REAL-WORLD Setting

Treatment of elderly patients with neoplasia is challenging. Age is a known prognostic factor in ovarian cancer but the optimal treatment of elderly patients has not been determined. We undertook a retrospective analysis to determine clinical practice in advanced-stage ovarian cancer patients older than 70 years of age. Methods: Medical records of women with high-grade serous ovarian cancer, stage III and IV were retrospectively analyzed. Results: A total of 735 patients were identified with a median age of 61.5 years. 22.4% among them were older than 70 years of age at diagnosis. First-line Progression-Free Survival (PFS) and Overall Survival (OS) were significantly worse in elderly patients in comparison to the younger ones [mPFS 11.3 months vs. 14.8 months, (p < 0.001) and mOS 30.2 months vs. 45.6 months (p < 0.001)]. However, elderly patients were characterized by worse ECOG-Performance Status and they were more frequently treated with Neoadjuvant Chemotherapy followed by Interval Debulking Surgery, while often they were more frequently denied debulking surgery compared to patients under 70 years of age. Moreover, elderly patients received more frequently monotherapy with platinum as frontline treatment. In contrast, there was no significant difference in the outcome of the debulking surgery in comparison to the younger patients or the frequency that gBRCA test was performed. Age over 70 years did not retain its significance for either Progression-Free Survival or Overall Survival when adjusted for all other reported prognostic factors. Conclusions: Elderly ovarian cancer patients have a worse prognosis. Comprehensive geriatric assessment should be performed for the optimal treatment of these patients.

Under-Treatment of Older Patients with Newly Diagnosed Epithelial Ovarian Cancer Remains an Issue

Older women with ovarian cancer have disproportionately poorer survival outcomes than their younger counterparts and receive less treatment. In order to understand where the gaps lie in the treatment of older patients, studies incorporating more detailed assessment of baseline characteristics and treatment delivery beyond the scope of most cancer registries are required. We aimed to assess the proportion of women over the age of 65 who are offered and receive standard of care for first-line ovarian cancer at two UK NHS Cancer Centres over a 5-year period (December 2009 to August 2015). Standard of care treatment was defined as a combination of cytoreductive surgery and if indicated platinum-based chemotherapy (combination or single-agent). Sixty-five percent of patients aged 65 and above received standard of care treatment. Increasing age was associated with lower rates of receiving standard of care (35% > 80 years old versus 78% of 65-69-year-olds, p = 0.000). Older women were less likely to complete the planned chemotherapy course (p = 0.034). The oldest women continue to receive lower rates of standard care compared to younger women. Once adjusted for Federation of Gynaecology and Obstetrics (FIGO) stage, Eastern Cooperative Oncology Group (ECOG) performance status and first-line treatment received, age was no longer an independent risk factor for poorer overall survival. Optimisation of vulnerable patients utilising a comprehensive geriatric assessment and directed interventions to facilitate the delivery of standard of care treatment could help narrow the survival discrepancy between the oldest patients and their younger counterparts.

A Prediction Model for Optimal Primary Debulking Surgery Based on Preoperative Computed Tomography Scans and Clinical Factors in Patients With Advanced Ovarian Cancer: A Multicenter Retrospective Cohort Study

OBJECTIVE

This study assessed the predictive value of preoperative computed tomography (CT) scans and clinical factors for optimal debulking surgery (ODS) in patients with advanced ovarian cancer (AOC).

METHODS

Patients with AOC in International Federation of Gynecology and Obstetrics (FIGO) stage III-IV who underwent primary debulking surgery (PDS) between 2016 and 2019 from nine tertiary Chinese hospitals were included. Large-volume ascites, diffuse peritoneal thickening, omental cake, retroperitoneal lymph node enlargement (RLNE) below and above the inferior mesenteric artery (IMA), and suspected pelvic bowel, abdominal bowel, liver surface, liver parenchyma and portal, spleen, diaphragm and pleural lesions were evaluated on CT. Preoperative factors included age, platelet count, and albumin and CA125 levels.

RESULTS

Overall, 296 patients were included, and 250 (84.5%) underwent ODS. The prediction model included age >60 years (P=0.016; prediction index value, PIV=1), a CA125 level >800 U/ml (P=0.033, PIV=1), abdominal bowel metastasis (P=0.034, PIV=1), spleen metastasis (P<0.001, PIV=2), diaphragmatic metastasis (P=0.014, PIV=2), and an RLNE above the IMA (P<0.001, PIV=2). This model had superior discrimination (AUC=0.788>0.750), and the Hosmer-Lemeshow test indicated its stable calibration (P=0.600>0.050). With the aim of maximizing the accuracy of prediction and minimizing the rate of inappropriate explorations, a total PIV ≥5 achieved the highest accuracy of 85.47% and identified patients who underwent suboptimal PDS with a specificity of 100%.

CONCLUSIONS

We developed a prediction model based on two preoperative clinical factors and four radiological criteria to predict unsatisfactory debulking surgery in patients with AOC. The accuracy of this prediction model needs to be validated and adjusted in further multicenter prospective studies.

Cardiovascular Health during and after Cancer Therapy

Certain cancer treatments have been linked to specific cardiovascular toxicities, including (but not limited to) cardiomyopathy, atrial fibrillation, arterial hypertension, and myocarditis. Radiation, anthracyclines, human epidermal growth factor receptor 2 (Her2)-directed therapies, fluoropyrimidines, platinums, tyrosine kinase inhibitors and proteasome inhibitors, immune checkpoint inhibitors, and chimeric antigen-presenting (CAR)-T cell therapy can all cause cardiovascular side effects. Management of cardiovascular dysfunction that occurs during cancer therapy often requires temporary or permanent cessation of the risk-potentiating anti-neoplastic drug as well as optimization of medical management from a cardiovascular standpoint. Stem cell or bone marrow transplant recipients face unique cardiovascular challenges, as do patients at extremes of age.

Age-Related Considerations in Cardio-Oncology

Cardio-Oncology has blossomed as a new field in cardiovascular medicine, in large part due to new therapies, which may have cardiovascular sequelae. Despite this, anthracyclines still serve as cornerstone therapy for most pediatric cancers, several solid tumors and hematological malignancies. Cardiotoxicity is the main limiting concern with anthracyclines, and this is particularly an issue in patients in extremes of age (both young and old patients). Pediatric hearts are susceptible for cardiotoxicity, while in older patients, concomitant risk factors may contribute to lower threshold for cardiotoxic effects. With increasing patient survival, a significant increase in elderly cancer patients and long-term cardiotoxicity effects of anthracyclines, a better mechanistic understanding of age-dependent processes-that define cardiotoxicity-is needed. This review sheds light on how age affects underlying molecular pathways of anthracycline-associated cardiotoxicity and aims to provide preventive strategies that can be used in clinical practice.

Olaparib treatment in older patients with ovarian cancer: need for 'real-world' data beyond clinical trials

Background

Ageing is a risk factor for cancer. Worldwide, the number and proportion of adults aged ≥65 will increase, along with the incidence of ovarian cancer. Older adults are under-represented in randomised clinical trials (RCTs), and those who are enrolled have a good performance status and no major health issues. These patients are not representative of older patients seen in everyday clinical practice; therefore, age-specific data on efficacy and toxicity of olaparib in the ‘real-world’ setting are lacking.

Methods

This observational study was conducted in the Central Jutland Region in Denmark. Data in unselected older (≥65) patients with known BRCA mutation receiving olaparib maintenance treatment for platinum-sensitive relapsed ovarian cancer were registered between 2015 and 2019. Toxicity and progression-free survival (PFS) were registered. No geriatric assessment has been performed.

Results

In total, 20 consecutive patients ≥65 years were included with a median age of 75 years (range: 65–85). Most of the patients (18/20) had ECOG PS: 0–1. Treatment interruption and dose reduction occurred in 65% of the patients. Toxicities of any grade occurred in 18 (90%), whereas grade 3/4 toxicities occurred in 6 patients (30%). Treatment was terminated due to disease progression or unacceptable toxicity in 13 (65%) patients. The median PFS was 6 months (range: 2–31), and the median follow-up was 15 months (range: 3–30).

Discussion

Our ‘real-world’ experience shows that unselected older patients represent a significant larger proportion in real life than in RCTs; furthermore, older patients in a real-world setting may experience more side effects possibly affecting the quality of life. The median PFS data suggest that older patients may not derive the same clinical benefit than their fit and younger counterparts.

There is a need to enrol vulnerable/frail older patients into RCTs, ensuring that data will also be applicable in standard clinical settings. Incorporating geriatric assessment into these trials should be encouraged.

Defining Undertreatment and Overtreatment in Older Adults With Cancer: A Scoping Literature Review

PURPOSE

The terms undertreatment and overtreatment are often used to describe inappropriate management of older adults with cancer. We conducted a comprehensive scoping review of the literature to clarify the meanings behind the use of the terms.

METHODS

We searched PubMed (National Center for Biotechnology Information), Embase (Elsevier), and CINAHL (EBSCO) for titles and abstracts that included the terms undertreatment or overtreatment with regard to older adults with cancer. We included all types of articles, cancer types, and treatments. Definitions of undertreatment and overtreatment were extracted, and categories underlying these definitions were derived through qualitative analysis. Within a random subset of articles, C.D. and K.P.L. independently performed this analysis to determine final categories and then independently assigned these categories to assess inter-rater reliability.

RESULTS

Articles using the terms undertreatment (n = 236), overtreatment (n = 71), or both (n = 51) met criteria for inclusion in our review (n = 256). Only 14 articles (5.5%) explicitly provided formal definitions; for the remaining, we inferred the implicit definitions from the terms' surrounding context. There was substantial agreement (κ = 0.81) between C.D. and K.P.L. in independently assigning categories of definitions within a random subset of 50 articles. Undertreatment most commonly implied less than recommended therapy (148; 62.7%) or less than recommended therapy associated with worse outcomes (88; 37.3%). Overtreatment most commonly implied intensive treatment of an older adult in whom the harms of treatment outweigh the benefits (38; 53.5%) or intensive treatment of a cancer not expected to affect an older adult in his/her remaining lifetime (33; 46.5%).

CONCLUSION

Undertreatment and overtreatment of older adults with cancer are imprecisely defined concepts. We propose new, more rigorous definitions that account for both oncologic factors and geriatric domains.

Ovarian Cancer in the Elderly: Time to Move towards a More Logical Approach to Improve Prognosis-A Study from the FRANCOGYN Group

Background and objective: Elderly and/or frail women with ovarian cancer are often undertreated. The aim of the study is to compare the effects of age and frailty on surgical approaches, postoperative complications, and prognosis in elderly women with ovarian cancer. Methods: A retrospective multicenter study of women ≥70 years were treated for ovarian cancer at seven French university hospitals between 2007 and 2015. Results: Of the 1119 women treated for ovarian cancer during the study period, 147 were ≥70 years and had complete data. Of these women, 65 were aged 70–74 years, and 82 were aged ≥75 years. Overall, 77% of the younger women (49/65) received optimal treatment compared with 51% (40/82) of the older women (p = 0.018). Women ≥75 years underwent fewer bowel resections (32% vs. 67%, p < 0.001) and experienced fewer postoperative complications (22.6% vs. 38.9%, p < 0.001); 53.2% of the women in this age group were treated by primary surgery or surgery only. These women also received more chemotherapy with platinum only (15% [9/56] vs. 2% [1/57], p = 0.007) and less bevacizumab (9% [5/56] vs. 32% [18/57], p = 0.003). Patients with greater frailty (a modified Charlson Comorbidity Index [mCCI] score >3) had a five-year survival rate of 30% versus 62% for those with a score ≤3 (p < 0.001). Conclusions: Surgeons modify their approach to treating ovarian cancer in women ≥75 years probably to reduce immediate postoperative complications. The prognosis is significantly worse in patients with greater frailty. Improvements to the sequence of treatments administered, with priority given to neoadjuvant chemotherapy in patients with greater frailty, could help increase the number of women who receive optimal treatment and improve their prognosis.

Exploring variations in ovarian cancer survival by age and stage (ICBP SurvMark-2): A population-based study

OBJECTIVE

The study aims to evaluate the differences in ovarian cancer survival by age and stage at diagnosis within and across seven high-income countries.

METHODS

We analyzed data from 58,161 women diagnosed with ovarian cancer during 2010-2014, followed until 31 December 2015, from 21 population-based cancer registries in Australia, Canada, Denmark, Ireland, New Zealand, Norway, and United Kingdom. Comparisons of 1-year and 3-year age- and stage-specific net survival (NS) between countries were performed using the period analysis approach.

RESULTS

Minor variation in the stage distribution was observed between countries, with most women being diagnosed with 'distant' stage (ranging between 64% in Canada and 71% in Norway). The 3-year all-ages NS ranged from 45 to 57% with Australia (56%) and Norway (57%) demonstrating the highest survival. The proportion of women with 'distant' stage was highest for those aged 65-74 and 75-99 years and varied markedly between countries (range:72-80% and 77-87%, respectively). The oldest age group had the lowest 3-year age-specific survival (20-34%), and women aged 65-74 exhibited the widest variation across countries (3-year NS range: 40-60%). Differences in survival between countries were particularly stark for the oldest age group with 'distant' stage (3-year NS range: 12% in Ireland to 24% in Norway).

CONCLUSIONS

International variations in ovarian cancer survival by stage exist with the largest differences observed in the oldest age group with advanced disease. This finding endorses further research investigating international differences in access to and quality of treatment, and prevalence of comorbid conditions particularly in older women with advanced disease.

Reasons for guideline non-adherence in older and younger women with advanced stage ovarian cancer

OBJECTIVE

This study aims to assess the reasons for guideline non-adherence in women with advanced stage ovarian cancer and whether these reasons differ according to age.

METHODS

All women diagnosed with advanced stage ovarian cancer, International Federation of Gynecology and Obstetrics (FIGO) IIb-IV, between 2015 and 2018 were selected from the Netherlands Cancer Registry. Treatment patterns and reasons for guideline non-adherence were analyzed according to age groups.

RESULTS

4210 women were included, of whom 34%, 33%, 26%, and 8% were aged <65, 65-75, 75-85, and ≥85 years respectively. With advancing age, less women received guideline-adherent treatment (decreasing from 70% to 2% in women aged <65 and ≥85 years respectively) and more women received best supportive care only (ranging from 4% to 69% in women aged <65 and ≥85 years respectively). The most prevalent reasons for guideline non-adherence differed according to age and included patient preference in older women, and functional status and extent of disease in younger women.

CONCLUSIONS

Most older women did not receive guideline-adherent care and patient preference was the most common reason for this decision. This knowledge provides insight in the current treatment decision-making process and highlights the importance of eliciting patient treatment preferences. Further prospective research is necessary to study the underlying motivation for women to decline guideline care and the extent to which shared decision-making influences treatment choice.

Long-Term Survival and Risk of Institutionalization in Onco-Geriatric Surgical Patients: Long-Term Results of the PREOP Study

OBJECTIVES

To evaluate long-term survival and institutionalization in onco-geriatric surgical patients, and to analyze the association between these outcomes and a preoperative risk score.

DESIGN

Prospective cohort study with long-term follow-up.

SETTING

International and multicenter locations.

PARTICIPANTS

Patients aged 70 years or older undergoing elective surgery for a malignant solid tumor at five centers (n = 229).

MEASUREMENTS

We assessed long-term survival and institutionalization using the Preoperative Risk Estimation for Onco-geriatric Patients (PREOP) score, developed to predict the 30-day risk of major complications. The PREOP score collected data about sex, type of surgery, and the American Society for Anesthesiologists classification, as well as the Timed Up & Go test and the Nutritional Risk Screening results. An overall score higher than 8 was considered abnormal.

RESULTS

We included 149 women and 80 men (median age = 76 y; interquartile range = 8). Survival at 1, 2, and 5 years postoperatively was 84%, 77%, and 56%, respectively. Moreover, survival at 1 year was worse for patients with a PREOP risk score higher than 8 (70%) compared with 8 or lower (91%). Of those alive at 1 year, 43 (26%) were institutionalized, and by 2 years, almost half of the entire cohort (46%) were institutionalized or had died. A PREOP risk score higher than 8 was associated with increased mortality (hazard ratio = 2.6; 95% confidence interval [CI] = 1.7-4.0), irrespective of stage and age, but not with being institutionalized (odds ratios = 1 y, 1.6 [95% CI = .7-3.8]; 2 y, 2.2 [95% CI = .9-5.5]).

CONCLUSION

A high PREOP score is associated with mortality but not with remaining independent. Despite acceptable survival rates, physical function may deteriorate after surgery. It is imperative to discuss treatment goals and expectations preoperatively to determine if they are feasible. Using the PREOP risk score can provide an objective measure on which to base decisions.

Comprehensive geriatric assessment is correlated to overall survival among gynaecologic oncology patients

OBJECTIVE

To investigate the correlation of comprehensive geriatric assessment to overall survival among older gynaecologic oncology patients.

METHODS

Between 2011 and 2017, patients >70 years had geriatric assessment before treatment. Geriatric assessment included the following tests: Old American resource and services, instrumental activities of daily living, modified Barthels index, mini-mental state examination, geriatric depression scale, mini-nutritional assessment, risk of falling and medication use. Overall survival was calculated for patients' groups below and above median tests scores. Univariate as well as multivariate analysis was done to evaluate the association between each variable and survival.

RESULTS

About 120 patients had geriatric assessment. Mean patients' age was 76.4 ± 5. A total of 78 Patients had ovarian cancer, 16 uterine cancer, 17 cervical cancer and 9 had other gynaecologic malignancies. No correlation was found between age, BMI (body mass index) and cancer type to overall survival. Patients with scores below cut-off values of modified Barthels index, instrumental activities of daily living, mini-nutritional assessment and mini-nutritional assessment had significantly shorter overall survival (P = 0.004, 0.031, 0.046 and 0.004, respectively). This remained significant in both univariate and multivariate analysis.

CONCLUSIONS

Gynaecologic oncology patients with lower geriatric assessment scores have significantly lower overall survival, irrespective of cancer type. Geriatric assessment tests allow objective assessment of older patients with worst prognosis before treatment planning.

Treatment strategies for recurrent ovarian cancer in older adult patients in Japan: a study based on real-world data

BACKGROUND/OBJECTIVE

Elderly patients with cancer are often at risk for undertreatment because of frailty, an aging-specific problem. However, current real-world conditions of recurrent ovarian cancer treatment in elderly patients remain unclear. This study aimed to clarify treatment patterns in elderly patients with recurrent ovarian cancer.

PATIENTS AND METHODS

We used an ovarian cancer database containing the diagnosis and initial therapy of all patients at the National Cancer Center Hospital in Japan from 2007 to 2014. Patients were stratified into the platinum-sensitive group and the platinum-resistant group. We retrospectively assessed chemotherapy use in patients aged ≤ 64, 65-69, 70-74, 75-79, and ≥ 80 years.

RESULTS

Among 253 patients (sensitive group: 135; resistant group: 118), by age group 91%, 95%, 100%, 100%, and 100% received chemotherapy in the sensitive group, and 79%, 67%, 50%, 29%, 0% received chemotherapy in the resistant group, respectively. In the resistant group, the percentage of patients aged 70-74 or 75-79 years who received chemotherapy was significantly lower than the percentage among patients aged ≤ 64 years, respectively (p = 0.01, p = 0.01). In multivariate analysis, age ≥ 70 years (odds ratio [OR], 4.412; 95% confidence interval (CI), 1.628-11.959; p = 0.004) and platinum-free interval < 3 months (OR, 3.434; 95% CI, 1.401-8.399; p = 0.007) were inversely associated with chemotherapy use.

CONCLUSIONS

Doctors and patients did not consider chemotherapy in patients aged ≥ 70 years with platinum-resistant disease. Older age was independently and inversely associated with chemotherapy use in platinum-resistant ovarian cancer. Our results highlight the importance of demographic information in clinical decision-making for elderly patients.

GERiatric Screening in the treatment of elderly patients with Ovarian Carcinoma (GERSOC): study protocol for a pragmatic, cluster randomised controlled trial

Background

Approximately 40% of the newly diagnosed patients with advanced ovarian cancer are aged 70 years or older. Standard treatment for advanced disease consists of cytoreductive surgery and combination chemotherapy. In older patients, standard treatment is often withheld or prematurely stopped due to suspected frailty. It remains challenging to distinguish fit elderly patients who can endure standard therapy from frail patients who may benefit from an adapted treatment strategy. As a comprehensive geriatric assessment (CGA) can contribute to the identification of frail patients and improve tailored therapy in this population, screening tests were developed to select those who may benefit from a CGA. However, the use of these geriatric screening tests has rarely been compared with usual clinical care. The GERSOC-trial will evaluate whether geriatric screening in elderly patients with advanced-stage ovarian cancer improves treatment completion and quality of life.

Methods

This pragmatic, cluster randomised controlled trial will be conducted at a minimum of 20 hospitals in the Netherlands. Hospitals are randomly assigned to geriatric screening care (in which a geriatric screening comprised of the G8 questionnaire and the Timed Up and Go test is performed), or care as usual (in which current usual care is continued). A total of 320 patients aged ≥ 70 years with primary, advanced-stage ovarian carcinoma will be included. Patients considered fit on geriatric screening will receive standard treatment; patients who are considered unfit will be referred to a geriatrician for analysis and treatment advice. The primary outcome is the percentage difference in completed standard and adapted therapies between the two study arms. Secondary outcomes include quality of life, cost-effectiveness and survival.

Discussion

This trial aims to gather evidence for the use of geriatric screening in treatment decision-making in elderly patients with advanced ovarian cancer. If proven feasible, beneficial and cost-effective, geriatric screening may be implemented in routine clinical practice.

Feasibility of initial treatment in elderly patients with ovarian cancer in Japan: a retrospective study

PURPOSE

The purpose of this study was to evaluate the real world situation and clarify the problem in initial treatment for elderly patients with ovarian cancer in Japan.

METHODS

We used the ovarian cancer database, containing all patients diagnosed and treated with International Federation of Gynecology and Obstetrics Stage I-IV ovarian cancer at the National Cancer Center Hospital in Japan from June 2008 to April 2013. Patients were stratified into two groups based on age: an elderly group, aged 70 years or older, and a younger group, aged below 70 years. We retrospectively assessed the rate of receiving standard therapy, and the feasibility and safety of chemotherapy compared with younger patients.

RESULTS

In total, 244 patients (elderly group, 36 patients; younger group, 208 patients) were analyzed. A significantly lower proportion of elderly patients than younger patients received standard therapy (15.7% vs. 32.5%, p = 0.026). Even for the elderly group, 95% patients underwent surgery in our institution. Conversely the rate of patients receiving nonstandard chemotherapy in the elderly group was significantly higher than in the younger group (30.5% vs. 9.6%, p = 0.01).

CONCLUSIONS

This study clarified the type of treatment being performed in the field, and the proportion of elderly ovarian cancer patients receiving standard therapy compared with younger patients in Japan. In addition, the actual situation of elderly patients in Japan might be different from that in Western countries. We need to evaluate the appropriate treatment for elderly patients in Japan.

Safety and Efficacy of Extended Bevacizumab Therapy in Elderly (≥70 Years) Versus Younger Patients Treated for Newly Diagnosed Ovarian Cancer in the International ROSiA Study

OBJECTIVE

The single-arm ROSiA study explored an extended duration of frontline bevacizumab-containing therapy for ovarian cancer. Post hoc analyses explored safety and efficacy according to age.

PATIENTS AND METHODS

After primary debulking surgery, patients with stage IIB-IV or grade 3 stage I-IIA ovarian cancer received 4-8 cycles of paclitaxel [weekly or every 3 weeks (q3w)], carboplatin AUC 5-6 q3w, and bevacizumab 15 (or 7.5) mg/kg q3w, followed by single-agent bevacizumab until progression or for up to 24 months. The primary end point was safety; progression-free survival (PFS) was a secondary end point.

RESULTS

Of 1021 patients treated, 121 (12%) were aged 70 years or older and 44 (4%) were 75 years or older. Compared with younger patients, more patients aged 70 years or older had hypertension at baseline, stage IV disease, and Eastern Cooperative Oncology Group performance status 1 or above. Bevacizumab was continued for more than 15 months in 49% of older versus 53% of younger patients. Older patients experienced higher incidences of all-grade anemia (44% vs 32%), diarrhea (35% vs 25%), and asthenia (22% vs 12%), and grade ≥3 hypertension (41% vs 22%) and thromboembolic events (7% vs 2%) compared with younger patients. Fatal bevacizumab-related adverse events occurred in 1 (0.8%) older versus 5 (0.6%) younger patients. Median PFS was 23.7 (95% confidence interval, 18.6-27.9) versus 25.6 (95% confidence interval, 23.7-28.4) months in patients aged 70 or older versus those younger than 70 years, respectively.

CONCLUSION

Bevacizumab-treated patients aged 70 years or older had higher incidences of anemia, low-grade diarrhea, and asthenia, and grade ≥3 hypertension and thromboembolic events than those younger than 70 years, but no other relevant increase in toxicity. Median PFS of approximately 2 years is similar to that in younger patients despite the worse prognosis. Older age should not preclude bevacizumab therapy for ovarian cancer in carefully selected patients aged 70 years or older. Given the higher background hypertension prevalence, elderly patients should be monitored more closely while receiving bevacizumab.

Outcome of surgery in advanced ovarian cancer varies between geographical regions; opportunities for improvement in The Netherlands

INTRODUCTION

The care for patients with epithelial ovarian cancer(EOC) is organised in eight different geographical regions in the Netherlands. This situation allows us to study differences in practice patterns and outcomes between geographical regions for patients with FIGO stage IIIC and IV.

METHODS

We identified all EOC patients who were diagnosed with FIGO stage IIIC or IV between 01.01.2008 and 31.12.2015 from the Netherlands Cancer Registry. Descriptive statistics were used to summarize treatment and treatment sequence(primary cytoreductive surgery(PCS) or neoadjuvant chemotherapy and interval cytoreductive surgery(NACT-ICS)). Moreover, outcome of surgery was compared between geographical regions. Multilevel logistic regression was used to assess whether existing variation is explained by geographical region and case-mix factors.

RESULTS

Overall, 6,741 patients were diagnosed with FIGO IIIC or IV disease. There were no differences in the percentage of patients that received any form of treatment between the geographical regions(range 80-86%, P = 0.162). In patients that received cytoreductive surgery and chemotherapy, a significant variation between the geographical regions was observed in the use of PCS and NACT-ICS(PCS: 24-48%, P < 0.001). The percentage of complete cytoreductive surgeries after PCS ranged from 10 to 59%(P < 0.001) and after NACT-ICS from 37 to 70%(P < 0.001). Moreover, geographical region was independently associated with the outcome of surgery, also when adjusted for treatment sequence(P < 0.001).

CONCLUSION

We observed a significant variation in treatment approach for advanced EOC between geographical regions in the Netherlands. Furthermore, the probability to achieve no residual disease differed significantly between regions, regardless of treatment sequence. This may suggest that surgical outcomes can be improved across geographical regions.

Treatment decision-making in elderly women with ovarian cancer: an age-based comparison

Objective

To investigate treatment choices and outcomes in women with ovarian cancer, comparing elderly (≥75 years) and younger patients (<75 years).

Methods

A single-center retrospective analysis of patients diagnosed with ovarian cancer between 2010 and 2015. The initial treatment plan and course of treatment were extracted from medical files.

Results

Of 128 included patients, 34% were aged ≥75 years. The initial treatment plan consisted of the combination of cytoreductive surgery and platinum-based doublet chemotherapy (ie, standard treatment) in only 10% of the elderly patients with an indication for this treatment. 5% of these patients completed this treatment without adaptations (compared with 85% and 48%, respectively, in younger patients). 38% of the elderly patients with an indication for cytoreductive surgery and chemotherapy received best supportive care only. Patient preference was an important reason to withhold standard treatment. Surgery- and chemotherapy-related complications and hospital admissions did not differ between groups. Median survival was lower in the elderly (p=0.002) and in patients receiving best supportive care (p<0.001).

Conclusions

Elderly patients were less frequently treated in accordance with the treatment guideline. To select those older patients who may benefit from (adapted) treatment is challenging. Future studies should evaluate determinants associated with treatment completion to improve outcomes in this vulnerable population.

Management of endometrial, ovarian and cervical cancer in the elderly: current approach to a challenging condition

PURPOSE

Gynaecological cancer management in older people represents a current challenge. Therefore, in the present paper, we aimed to gather all the evidence reported in the literature concerning gynecological cancers in the elderly, illustrating the state of art and the future perspectives.

METHODS

We searched MEDLINE (PubMed), EMBASE, Cochrane Central Register of Controlled Trials, IBECS, BIOSIS, Web of Science, SCOPUS and Grey literature (Google Scholar; British Library) from January 1952 to May 2017, using the terms "ovarian cancer", "endometrial cancer", "cervical cancer", "gynecological cancers" combined with 'elderly', 'cancer', 'clinical trial' and 'geriatric assessment'.

RESULTS

The search identified 81 citations, of which 65 were potentially relevant after initial evaluation and met the criteria for inclusion and were analyzed. We divided all included studies into three different issue: "Endometrial cancer", "Ovarian cancer" and "Cervical cancer".

CONCLUSIONS

The present literature review shows that, in spite of the higher burden of comorbidities, elderly patients can also benefit from standard treatment to manage their gynecological cancers. It is important to overcome the common habit of undertreating the elderly patients because they are more fragile and with a lower life expectancy than their younger counterpart. Further trials with elderly women are warranted.

PARP inhibitors in older patients with ovarian and breast cancer: Young International Society of Geriatric Oncology review paper

Breast and ovarian cancer are common malignancies among older adults, causing significant morbidity and mortality. Although most cases of breast and ovarian cancer are sporadic, a significant proportion is caused by mutations in cancer susceptibility genes, most often breast cancer susceptibility genes (BRCA) 1 and 2. Furthermore, some breast and ovarian tumors are phenotypically similar to those with BRCA mutations, a phenomenon known as "BRCAness". BRCA mutations and "BRCAness" lead to defects in DNA repair, which may be a target for therapeutic agents such as Poly ADP-Ribose Polymerase (PARP) inhibitors. PARP inhibitors are novel medications which lead to double-strand breaks resulting in cell death due to synthetic lethality, and which have been shown to be effective in patients with advanced breast and ovarian cancers with or without BRCA mutations. Three different PARP inhibitors (olaparib, niraparib, and rucaparib) have been approved for the treatment of ovarian cancer and one (olaparib) for breast cancer harboring BRCA mutations. Here, we review the currently available evidence regarding the use of PARP inhibitors for the treatment of patients with breast and ovarian cancer, with a particular focus on the inclusion of older adults in clinical trials of these therapies. Additionally, we provide an overview of currently ongoing studies of PARP inhibitors in breast and ovarian cancer, and include recommendations for increasing the evidence-base for using these medications among older patients.

Can Vulnerable Elders Survey-13 predict the impact of frailty on chemotherapy in elderly patients with gynaecological malignancies?

The management of gynaecological cancers in elderly women and high-risk patients is an even more relevant issue, because the increase in longevity and comorbidities. The assumption of frailty based on age alone may lead to inadequate and inappropriate treatment and frailty assessment is recommended. The aim of this study was to assess if Vulnerable Elders Survey-13 (VES-13), as indicator of frailty, can predict the toxicity of chemotherapy in gynaecological cancers.VES-13 was administered to patients aged ≥ 70 years with ovarian, endometrial and cervical cancers who underwent chemotherapy from 2010 to 2016.Eighty-four patients aged ≥ 70 years (mean age 74.6) were included, 36 patients (42.9%) resulted vulnerable (score ≥ 3). Thrombocytopenia and anaemia were more prevalent in the vulnerable subjects (81.3% versus 18.7%, P = .0005, and 81.8% versus 18.2%, P = .005, respectively), while neutropenia was similar between the 2 groups. Vulnerable women had higher risk of non-haematological toxicities. Most of the patients (77.4%) completed chemotherapy, but dose reductions and discontinuations were more common in the vulnerable group (66.7% versus 33.3%, P = .07 and 68.4% versus 31.6%, P = .01, respectively).To our knowledge, this is the first study to evaluate VES-13 exclusively in elderly women with gynaecological cancers. VES-13 may be useful to stratify this category of patients according to vulnerability in order to identify women at risk of toxicity and to prevent complications induced by chemotherapy.

Age-related differences in prognosis and prognostic factors among patients with epithelial ovarian cancer

Approximately 40% of all patients with ovarian cancer in Japan are aged ≥65 years. The aim of the present study was to evaluate the differences in prognosis and prognostic factors between elderly and younger patients with epithelial ovarian cancer. A total of 114 patients with International Federation of Gynecology and Obstetrics (FIGO) stage I-IV ovarian cancer who were initiated on primary treatment at the Osaka City University Hospital (Osaka, Japan) were included in this study. Patient characteristics, treatment outcome and prognosis were compared between elderly (aged ≥65 years) and younger patients, and the prognostic factors associated with overall survival were evaluated by univariate and multivariate analyses. The most common histological type in younger patients was clear cell carcinoma (33.8%) vs. serous carcinoma in elderly patients (44.1%), with a significant difference in the distribution of histological type (P=0.006). Complete resection was achieved in 56.2% of younger patients compared with 32.4% of elderly patients (P=0.03). The rates of standard primary treatment were comparable (56.7% of younger vs. 50.0% of elderly patients). Overall and disease-free survival did not differ significantly between the two groups. Multivariate analyses identified FIGO stage and standard primary therapy as prognostic factors in younger patients and performance status in elderly patients. Age was not an independent significant prognostic factor among patients with ovarian cancer. Therefore, performance status, rather than age, should be considered when selecting the optimal treatment for elderly patients based on objective assessment.

Treatment and outcome of elderly patients with advanced stage ovarian cancer: A nationwide analysis

OBJECTIVE

To provide an overview of treatment strategies for elderly patients with advanced stage epithelial ovarian cancer (EOC) in daily practice, evaluate changes over time and relate this to surgical mortality and survival.

METHODS

All women diagnosed with advanced stage (FIGO IIB and higher) EOC between 2002 and 2013 were selected from the Netherlands Cancer Registry (n=10,440) and stratified by age, stage and period of diagnosis. Elderly patients were defined as aged ≥70years. Time trends in treatment patterns and postoperative mortality were described by age category and tested using multivariable logistic regression. Relative survival was calculated.

RESULTS

With advancing age, less patients received ((neo-)adjuvant) treatment. Over time, elderly patients were less often treated (OR 2002-2004 versus 2011-2013: 0.73; 95%CI:0.58-0.92). But if treated, more often standard treatment was provided and 30-day postoperative mortality decreased from 4.5% to 1.9% between 2005 and 2007 and 2011-2013. In all age categories treatment shifted from primary surgery towards primary chemotherapy, in patients aged 70-79years combination therapy increased (+5%) between 2002 and 2004 and 2011-2013. Five-year relative survival for patients diagnosed in 2008-2010 aged <70years was 34% compared to 18% for elderly patients.

CONCLUSION

Large treatment differences exist between younger and elderly patients. Over time, selection of elderly patients eligible for curative surgical treatment may have improved. More elderly patients were treated with neoadjuvant chemotherapy while less patients underwent surgery and simultaneously postoperative mortality decreased. However, the large and increasing number of elderly patients without treatment and the large survival gap suggests opportunities for further improvements in the care for elderly EOC patients.

Ovarian Cancer in Elderly Patients: Patterns of Care and Treatment Outcomes According to Age and Modified Frailty Index

Objective

The present study assessed the predictive value of age and Modified Frailty Index (mFI) on the management of primary epithelial ovarian cancer (EOC) patients aged 70 years or older (elderly).

Methods

A retrospective multicenter study selected elderly EOC patients treated between 2006 and 2014. Treatments were analyzed according to the following age group categories: (1) 70 to 75 years versus (2) older than 75 years, and mFI of less than 4 (low frailty) versus greater than or equal to 4 (high frailty).

Results

Seventy-eight patients were identified (40 in age group 1 and 38 in age group 2). The mFI was greater than or equal to 4 in 23 women. Median age of low frailty and high frailty was not significantly different (75.6 vs 75.3). Comorbidities were equally distributed according to age, whereas diabetes, hypertension, obesity, and chronic renal failure were more frequent in the high-frailty group. Performance status was different only according to mFI. Twenty percent of age group 1 versus 55.3% of age group 2 underwent none or only explorative surgical approach (P = 0.003), whereas surgical approaches were similar in the 2 frailty groups. The rate of postoperative complications was higher in high-frailty patients compared with low-frailty patients (23.5% vs 4.3%; P = 0.03). Chemotherapy was administered to all the patients, a monotherapy regimen to 50% of them. No differences in toxicity were registered, except more hospital recovery in the high-frailty cohort. Median survival time was in favor of younger patients (98 versus 30 months) and less-frailty patients (56 vs 27 months).

Conclusions

Elderly EOC patients can receive an adequate treatment, but patients who are older than 75 years can be undertreated, if not adequately selected. The pretreatment assessment of frailty through mFI could be suggested in the surgical and medical management.

Cardio-oncology in the older adult

Heart disease and cancer are the leading causes of death in older adults. Many first-line cancer treatments have the potential for cardiotoxicity. Age-related risk factors, pre-existing cardiac disease, and a high prevalence of comorbidities are reasons for increased cardiotoxicity in older adults. Concerns regarding cardiotoxicity may lead to frailty bias and undertreatment, resulting in suboptimal outcomes. There is an urgent need for geriatric-specific evidence and guidelines to help tailor care for this vulnerable group. A multi-disciplinary approach based on close collaboration between oncologists, cardiologists, and geriatricians, among other specialist clinicians is essential.

Age is associated with prognosis in serous ovarian carcinoma

Purpose

The survival duration of elderly patients with epithelial ovarian carcinoma is shorter than that of their younger counterparts. This variation in survival duration is likely attributed to differences in the distribution of histological type or grade, International Federation of Gynecology and Obstetrics (FIGO) staging, and undertreatment, but this observation remains controversial. This study aimed to investigate the biological factors other than selection bias associated with the decreased survival of elderly patients with ovarian carcinoma.

Methods

A total of 314 serous ovarian cancer (SOC) patients from Jiangsu Institute of Cancer Research (JICR, PRC) between 2002 and 2012 were retrospectively analyzed, and 774 cases from MD Anderson Cancer Center (MDACC, USA) between 1992 and 2012 were used for validation. The 8-hydroxy-2′-deoxyguanine (8-OHdG) concentration in leukocyte DNA was evaluated by using commercially available enzyme-linked immunosorbent assay kits, and tissue expression was assayed through immunohistochemistry. The associations between survival durations and covariates were assessed by using a Cox proportional hazards model and by conducting a log-rank test.

Results

Advanced age ≥ 65 years was correlated with high histological grade (p = 0.02), performance status (p = 0.03), primary treatment (p = 0.00), and suboptimal surgery outcome (p = 0.04) in SOC patients from JICR. Age, FIGO stage, histological grade, and optimal surgery were independently associated with the progression-free survival (PFS; p = 0.03, p = 0.03, p = 0.02, and p = 0.04, respectively) and overall survival (OS; p = 0.02, p = 0.04, p = 0.02, and p = 0.02, respectively) of the SOC patients from JICR. The 8-OHdG concentration in the leukocyte DNA was higher in the elderly patients than in the younger cases. The high 8-OHdG concentration in the leukocyte DNA indicated poorer median OS (30.0 months, confidence interval [CI]: 23.5–36.5 vs. 42.8 months, [CI] 38.3–47.2) and PFS (14.6 months, [CI] 11.9–17.2 vs. 18.9 months, [CI] 14.4–23.4) than those of their corresponding counterparts in the SOC patients who achieved a clinical complete response from primary treatment.

Conclusions

Compared with younger cases, elderly patients with SOC were commonly characterized by high tumor grade, poor performance status, and undertreatment. High 8-OHdG concentration in leukocyte DNA was associated with advanced age and poor prognosis in SOC patients.

Contribution of age to clinical trial enrollment and tolerance with ovarian cancer

INTRODUCTION

Increasing age has been correlated with shorter survival in ovarian cancer patients, a finding attributed to diminished tolerance of standard therapy. Elderly patients, however, are less likely to enroll on clinical trials; thus, limited data exists to evaluate their response to front line treatment. This study describes how elderly patients on trial fared, with respect to toxicity and response, compared to younger women.

METHODS

A retrospective cohort study was performed of ovarian cancer patients enrolled in front line chemotherapy trials at our institution between 2000 and 2013. Patients were dichotomized by age: <70 and ≥70years. Clinical, pathologic, and treatment characteristics were recorded and analyzed using SAS version 9.3.

RESULTS

336 patients were enrolled. Of these, 79 (23.5%) were ≥70yrs. Demographics were similar between the two groups. Compared to patients <70, those ≥70 completed a comparable number of chemotherapy cycles (p=0.16) and had similar numbers of dose modifications (p=0.40) and delays (p=0.26). Both hematologic and non-hematologic toxicities occurred at similar rates as well. Age≥70 (HR 1.8, 95% CI 1.27-2.54, p=0.0009), stage III/IV (HR 3.44, 95% CI 1.08-10.95, p=0.036), and residual disease (HR 2.63, 95% CI 1.82-3.78, p<0.0001) were independently predictive of shorter overall survival.

CONCLUSION

Our data continues to support reports of shorter survival for older women with ovarian cancer. With physician bias removed and similar chemotherapy tolerance noted, our study suggests that inherent tumor biology may be a significant contributor. Further research is needed to identify the mechanisms which contribute to the inequality that age imposes on outcomes.

Chemotherapy for Elderly Ovarian Cancer Patients

Objective

Ovarian cancer is the most lethal cancer involving the female pelvic reproductive system. Its incidence increases with age and with an aging population, its prevalence should also increase. The goal of our retrospective study is to report our experience in treating women over 65 years of age, with a diagnosis of primary ovarian cancer, using standard intravenous chemotherapy.

Methods

The medical records of 78 patients>65 years of age diagnosed with primary ovarian cancer at the Yale Cancer Center between 1996–2006 were retrospectively reviewed and included in our analysis. Patients had stage I–IV disease (stage I n=5, stage II n=8, stage III n=36, stage IV n=25, unknown n=4).

Results

Sixty-three of 78 women (80.8%) completed the prescribed regimen; and 62 women did not require a dose reduction or chemotherapy discontinuation. The most common reason for a dose reduction or treatment discontinuation was fatigue (6.4%), neutropenia (2.6%), patient preference (2.6%), and multiple co-morbidities (2.6%). The most commonly used regimen was paclitaxel 175mg/m² and carboplatin AUC 5. The hazard ratio for PFS and OS for patients who had dose reduction/discontinuation versus those who completed the prescribed dose was 1.3 (95% CI 0.51–3.26) and 0.63 (95% CI 0.17–2.33), respectively.

Conclusions

Our findings illustrate that elderly women are able to tolerate standard chemotherapy with relatively few significant adverse effects. While different treatment modalities in ovarian cancer are continually being evaluated, additional prospective studies are required to better understand the tolerability and efficacy of such treatment in the elderly population.

Chemotherapy of ovarian cancer in elderly patients

Epithelial ovarian cancer is primarily a disease of older women. Advanced age is risk factor for decreased survival. Optimal surgery and the safe and effective administration of chemotherapy are essential for prolonged progression-free and overall survival (OS). In this article, the available regimens in both the primary treatment and relapsed setting are reviewed.
