Assessment of treatment factors and clinical outcomes in cervical cancer in older women compared to women under 65 years old

Utilisation Patterns of Radiotherapy Among Older Patients: Insights from Portuguese National Cancer Registry Data

INTRODUCTION

Radiation therapy (RT) will be required by millions of those aged 70 or older by 2040 based on European growth in cancer incidence among this age group.

PURPOSE

This study evaluates the use of external radiotherapy (EBRT) using data from the Portuguese National Cancer Registry (RON), analysing various cancer locations and age groups. A comparative analysis was conducted between actual EBRT utilization and comorbidity-adjusted optimal rates.

METHODS

Based on RON's data, cancer diagnoses from January to June 2018 were analysed. Optimal Utilization Proportions (OUP) of EBRT were obtained from European SocieTy for Radiotherapy and Oncology (ESTRO), Health Economics in Radiation Oncology (HERO) project. Actual utilization percentages (AUP) were calculated using national cancer registry data, and a comparative analysis adjusting for comorbidities was conducted.

RESULTS

For most cancer locations and age groups, the actual EBRT utilisation fell below the ESTRO-HERO recommendations, with potential untreated patients estimated at 22% of all new cancer cases across all age groups. Disparities were observed for older patients, such as breast cancer EBRT actual utilisation declining from 68% to 25% for patients aged under 70 and 85 or older, respectively. Also, cervix cancer patients aged 75 or older exhibited nearly 100% optimal EBRT utilisation. Conversely, older patients with bladder and colon cancer had significantly lower RT actual utilisation rates. Comorbidity-adjusted EBRT utilisation rates for lung, rectal, cervix, and breast cancers in patients aged 70-79 did not reached ESTRO-HERO task force recommended rates. The actual EBRT usage in Portugal failed to meet the comorbidity-adjusted optimal utilisation rate for all cancer locations and age groups. Nevertheless, Portuguese actual EBRT for rectal and prostate cancer, exceeded the actual rates in Australian cohort.

CONCLUSION

While EBRT is essential for older adults with cancer, disparities and suboptimal utilization highlight opportunities for improving cancer care provision.

Prognostic nomogram for early-stage cervical cancer in the elderly: A SEER database analysis

Background

To identify key clinical factors affecting the survival of elderly patients with early-stage cervical cancer and to construct a nomogram for predicting their prognosis.

Methods

Patients (aged ≥ 65 years old) diagnosed with cervical cancer between 2004 and 2015 at clinical stages IA to IIA were included in this study. Diagnosis was confirmed via pathological examination, and the cases were randomly divided into a training or a validation group in a 7:3 ratio. Univariate and multivariable Cox regression analyses were performed to identify independent factors affecting the prognosis of elderly early-stage cervical cancer patients, based on which a nomogram was constructed to predict their 12-, 24- and 36-month overall survival (OS). The nomogram's performance was evaluated using receiver operating characteristic (ROC) curves, calibration curves and decision curve analysis (DCA) curves.

Results

A total of 686 patients were identified as eligible and assessed. Multivariable Cox proportional hazard regression analysis revealed that age, tumor diameter, marital status and surgical intervention were independent prognostic factors for elderly individuals with early-stage cervical cancer, which were then used to construct the nomogram. The calibration curves showed a strong correlation between predicted and observed survival rates, and Kaplan-Meier survival curves for different risk subgroups demonstrated significant survival differences (P < 0.001). DCA confirmed the nomogram's clinical utility in predicting the prognosis of elderly patients with early-stage cervical cancer.

Conclusion

The prognostic model developed in this study can accurately predict the OS of elderly patients with early-stage cervical cancer, showing high concordance with actual clinical outcomes.

A Diagnostic Nomogram Incorporating Prognostic Nutritional Index for Predicting Vaginal Invasion in Stage IB - IIA Cervical Cancer

INTRODUCTION

With the advancements in cancer prevention and diagnosis, the proportion of newly diagnosed early-stage cervical cancers has increased. Adjuvant therapies based on high-risk postoperative histopathological factors significantly increase the morbidity of treatment complications and seriously affect patients' quality of life.

OBJECTIVES

Our study aimed to establish a diagnostic nomogram for vaginal invasion (VI) among early-stage cervical cancer (CC) that can be used to reduce the occurrence of positive or close vaginal surgical margins.

METHODS

We assembled the medical data of early-stage CC patients between January 2013 and December 2021 from the Fujian Cancer Hospital. Data on demographics, laboratory tests, MRI features, physical examination (PE), and pathological outcomes were collected. Univariate and multivariate logistic regression analyses were employed to estimate the diagnostic variables for VI in the training set. Finally, the statistically significant factors were used to construct an integrated nomogram.

RESULTS

In this retrospective study, 540 CC patients were randomly divided into training and validation cohorts according to a 7:3 ratio. Multivariate logistic analyses showed that age [odds ratio (OR) = 2.41, 95% confidence interval (CI), 1.29-4.50, P = 0.006], prognostic nutritional index (OR = 0.18, 95% CI, 0.04-0.77, P = 0.021), histological type (OR = 0.28, 95% CI, 0.08-0.94, P = 0.039), and VI based on PE (OR = 3.12, 95% CI, 1.52-6.45, P = 0.002) were independent diagnostic factors of VI. The diagnostic nomogram had a robust ability to predict VI in the training [area under the receiver operating characteristic curve (AUC) = 0.76, 95% CI: 0.70-0.82] and validation (AUC = 0.70, 95% CI: 0.58-0.83) cohorts, and the calibration curves, decision curve analysis, and confusion matrix showed good prediction power.

CONCLUSION

Our diagnostic nomograms could help gynaecologists quantify individual preoperative VI risk, thereby optimizing treatment options, and minimizing the incidence of multimodality treatment-related complications and the economic burden.

Nomogram for prognosis of elderly patients with cervical cancer who receive combined radiotherapy

This retrospective study identified prognostic factors to help guide the clinical treatment of elderly patients (≥ 65 years) with cervical cancer who had undergone radiotherapy. A personalized model to predict 3- and 5-years survival was developed. A review was conducted of 367 elderly women with cervical cancer (staged II-III) who had undergone radiotherapy in our hospital between January 2012 and December 2016. The Cox proportional hazards regression model was used for survival analysis that considered age, hemoglobin, squamous cell carcinoma antigen, pathologic type, stage, pelvic lymph node metastasis status, and others. A nomogram was constructed to predict the survival rates. The median follow-up time was 71 months (4-118 months). The 3- (5-) years overall, progression-free, local recurrence-free, and distant metastasis-free survival rates were, respectively, 91.0% (84.4%), 92.3% (85.9%), 99.18% (99.01%), and 99.18% (97.82%). The following were significant independent prognostic factors for overall survival: tumor size, pre-treatment hemoglobin, chemotherapy, and pelvic lymph node metastasis. The C-index of the line chart was 0.699 (95% CI 0.652-0.746). The areas under the receiver operating characteristic curves for 3- and 5-years survival were 0.751 and 0.724. The nomogram was in good concordance with the actual survival rates. The independent prognostic factors for overall survival in elderly patients with cervical cancer after radiotherapy were: tumor size, pre-treatment hemoglobin, chemotherapy, and pelvic lymph node metastasis. The novel prognostic nomogram based on these factors showed good concordance with the actual survival rates and can be used to guide personalized clinical treatment.

Cervical Cancer Stage at Diagnosis and Survival among Women ≥65 Years in California

BACKGROUND

Through adequate screening and follow-up, cervical cancer can be prevented or detected at early-stage (stage I), which is related to excellent survival. Current guidelines recommend discontinuing screening for women ≥65 years with history of normal Pap and/or HPV tests, potentially leaving this age group vulnerable. This study examined late-stage disease in a population-based cohort.

METHODS

Using California Cancer Registry data, we identified 12,442 patients ages ≥21 years with a first primary cervical cancer diagnosed during 2009-2018. Proportions of late-stage disease (stages II-IV) and early- and late-stage 5-year relative survival are presented by the age group. Among patients ages ≥65 years, multivariable logistic regression estimated associations of sociodemographic and clinical characteristics with late-stage cervical cancer.

RESULTS

Nearly one fifth of patients (n = 2,171, 17.4%) were ≥65 years. More women ages ≥65 years (71%) presented with late-stage disease than younger women (48% in patients ages <65). Late-stage 5-year relative survival was lower for women ≥65 years (23.2%-36.8%) compared with patients <65 (41.5%-51.5%). Characteristics associated with late-stage cervical cancer in women ≥65 years included older age [odds ratio (OR), 1.02; 95% confidence interval (CI), 1.01-1.04; each year], non-adenocarcinoma histologic subtypes, and comorbidities (OR, 1.59; 95% CI, 1.21-2.08).

CONCLUSIONS

There remains a significant burden of advanced cervical cancer in women ≥65.

IMPACT

Efforts should be made to better understand how the current screening paradigm is failing women of 65 years and older. Future work should focus on determining past screening history, lapses in follow-up care, and non-invasive testing approaches.

Comparison of oncological outcomes in elderly early-stage cervical cancer patients treated with radical surgery or radiotherapy: A real-world retrospective study with propensity score matching

Objective

To compare the oncological outcomes of radical surgery and radical radiotherapy in elderly (over 65 years) patients with early-stage cervical cancer (IB-IIA).

Methods

Elderly patients with stage IB-IIA cervical cancer treated at Peking Union Medical College Hospital from January 2000 to December 2020 were retrospectively reviewed. All patients were divided into the radiotherapy group (RT group) and the operation group (OP group) according to their primary intervention. Propensity score matching (PSM) analysis was performed to balance the biases. The primary outcome was overall survival (OS), and the secondary outcomes were progression-free survival (PFS) and adverse effects.

Results

A total of 116 patients were eligible for the study (47 in the RT group, and 69 in the OP group), and after PSM, 82 patients were suitable for further analysis (37 in the RT group, and 45 in the OP group). In the real-world setting, it was found that compared with radiotherapy, operation was more frequently selected for elderly cervical cancer patients with adenocarcinoma (P < 0.001) and IB1 stage cancer (P < 0.001). The 5-year PFS rates between the RT and OP groups were not significant (82.3% vs. 73.6%, P = 0.659), and the 5-year OS rate of the OP group was significantly better than that in the RT group (100% vs. 76.3%, P = 0.039), especially in patients with squamous cell carcinoma (P = 0.029) and tumor size of 2~4 cm with G2 differentiation (P = 0.046). There was no significant difference in PFS between the two groups (P = 0.659). In the multivariate analysis, compared with operation, radical radiotherapy was an independent risk factor of OS (hazard ratio = 4.970, 95% CI, 1.023~24.140, P = 0.047). No difference was observed in adverse effects between the RT and OP groups (P = 0.154) and in ≥grade 3 adverse effects (P = 0.852).

Conclusion

The study found that surgery was more frequently selected for elderly cervical cancer patients with adenocarcinoma and IB1 stage cancer in the real-world setting. After PSM to balance the biases, it showed that compared with radiotherapy, surgery could improve the OS of elderly early-stage cervical cancer patients and was an independent protective factor of OS in elderly early-stage cervical cancer patients.

Disparities in Diagnosis and Treatment of Cervical Adenocarcinoma Compared With Squamous Cell Carcinoma: An Analysis of the National Cancer Database, 2004-2017

OBJECTIVES

The aim of the study are to compare trends in diagnosis and treatment of adenocarcinoma of the cervix (AC) to squamous cell carcinoma of the cervix (SCC) and to examine associations between stage at diagnosis and guideline-concordant treatment with race, age, and insurance type for AC and SCC.

MATERIALS AND METHODS

We performed a retrospective cohort study of cervical AC ( n = 18,811) and SCC ( n = 68,421) from the 2004-2017 National Cancer Database. We used generalized linear models to evaluate trends in frequency of histologies and to evaluate associations between race, age, and insurance status with stage of diagnosis and receipt of National Comprehensive Cancer Network guideline-concordant treatment for AC and SCC.

RESULTS

The proportion of AC relative to SCC increased from 19.4% (95% CI = 18.4-20.5) to 23.2% (95% CI = 22.2-24.2) from 2004 to 2017 ( p < .001). Compared with SCC, women with AC were younger, more likely to be White, and privately insured ( p < .001). Older women with AC were 44% less likely to be diagnosed with early-stage disease than younger women (adjusted relative risk = 0.56, 95% CI = 0.52-0.60); there was no significant difference for SCC. Black women with AC were 16% less likely to be diagnosed with early-stage disease (adjusted relative risk [aRR] = 0.84, 95% CI = 0.79-0.89) than White women. Women with public insurance were less likely to be diagnosed at an early stage for both AC (aRR = 0.81, 95% CI = 0.78-0.84) and SCC (aRR = 0.79, 95% CI = 0.77-0.81). Rates of guideline-concordant treatment were similar for AC and SCC, with minimal differences by age, race, and insurance.

CONCLUSIONS

As the proportion of AC to SCC rises, important race and age-related disparities must be addressed to reduce unnecessary morbidity and death.

Underscreening, overscreening, and guideline-adherent cervical cancer screening in a national cohort

OBJECTIVE

To explore rates of under- and overscreening for cervical cancer among a national cohort.

METHODS

The MarketScan database, a national administrative database of employee-sponsored insurance, was queried for elements relevant to cervical cancer screening among women aged 21-65 with 6 years of continuous enrollment (2015-2019). Average-risk women were defined as those without high-risk medical conditions or abnormal screening histories, and without evidence of hysterectomy with removal of the cervix for benign indications. Average-risk women were considered adequately screened if they had Pap tests alone at 2.5-3.5 year intervals, or HPV tests or co-tests at 4.5-5.5 year intervals. Logistic regressions were used to predict the odds of receiving guideline-adherent screening, underscreening, and overscreening.

RESULTS

Among 1,872,809 eligible patients, 1,471,063 (78.5%) qualified for routine screening. Of these, only 18.1% received guideline-adherent screening, and 25.4% were unscreened during the 6-year period. Younger women (aged 21-39) were more likely to be overscreened [OR 1.46]. Older women (aged 50-64) were more likely to be underscreened or unscreened during the study period [OR 2.54]. Guideline-adherent screening was highest with HPV testing alone (80%) followed by co-testing (44%), and lowest with cytology alone (15%). A total of 329,062 women in this general population sample (18%) met high-risk criteria that required increased frequency of screening.

CONCLUSIONS

High rates of both underscreening and overscreening indicate a need for additional strategies to improve guideline-adherent care.

Eligibility for cervical cancer screening exit: Comparison of a national and safety net cohort

OBJECTIVE

To determine eligibility for discontinuation of cervical cancer screening.

METHODS

Women aged 64 with employer-sponsored insurance enrolled in a national database between 2016 and 2018, and those aged 64-66 receiving primary care at a safety net health center in 2019 were included. Patients were evaluated for screening exit eligibility by current guidelines: no evidence of cervical cancer or HIV-positive status and no evidence of cervical precancer in the past 25 years, and had evidence of either hysterectomy with removal of the cervix or evidence of fulfilling screening exit criteria, defined as two HPV screening tests or HPV plus Pap co-tests or three Pap tests within the past 10 years without evidence of an abnormal result.

RESULTS

Of the 590,901 women in the national claims database, 131,059 (22.2%) were eligible to exit due to hysterectomy (1.6%) or negative screening (20.6%). Of the 1544 women from the safety net health center, 528 (34.2%) were eligible to exit due to hysterectomy (9.3%) or negative screening (24.9%). Most women did not have sufficient data available to fulfill exit criteria: 382,509 (64.7%) in the national database and 875 (56.7%) in the safety net hospital system. Even among women with 10 years of insurance claims data, only 41.5% qualified to discontinue screening.

CONCLUSIONS

Examining insurance claims in a national database and electronic medical records at a safety net institution led to remarkably similar findings: two thirds of women fail to qualify for screening exit. Additional steps to ensure eligibility prior to screening exit may be necessary to decrease preventable cervical cancers among women aged >65.

Influence of age on treatment and prognosis of invasive cervical cancer

OBJECTIVE

Invasive cervical cancer is considered a young women's disease, however up to 20 % of cases develop cervical cancer at advanced ages. The aim was to characterize invasive cervical cancer in women aged 65 and older assessing age-specific survival differences.

STUDY DESIGN

A retrospective study including cervical cancer patients was conducted at Hospital del Mar Barcelona from July-2007 to December-2016. Women were stratified: <65 or ≥65years. Clinical and pathological data were collected. Multivariate analysis was used to compare outcomes. Adjusted hazard ratios with 95 % confidence intervals for disease-free survival, and overall survival were estimated using Cox proportional hazards models.

RESULTS

124 patients with invasive cervical cancer (n = 87 < 65years and n = 37 ≥ 65years) were included. At diagnosis, 48.3 % of <65years patients were diagnosed at advanced stages, while 64.9 % in ≥65years (p = 0.018). Standard treatment was given to 83.9 % of patients in <65years group compared to 62.2 % in ≥65years (p = 0.015). Disease-free survival and overall survival showed no significant differences between groups. Age ≥65 did not predict worse disease-free survival (HR: 0.3 95 %CI, 0.04-3.1, p = 0.347) or overall survival (HR: 0.82 95 %CI, 0.3-2.3, p = 0.729).

CONCLUSION

Invasive cervical cancer was diagnosed at advanced stages and was treated less frequently with radical intention in patients ≥65years; overall survival and disease-free survival were similar to those cervical cancer diagnosed at younger ages.

Cancer Screening Among Older Adults: a Geriatrician's Perspective on Breast, Cervical, Colon, Prostate, and Lung Cancer Screening

PURPOSE OF REVIEW

We summarize the evidence of benefits, harms, and tools to assist in individualized decisions among older adults in screening for breast, prostate, colon, lung, and cervical cancer.

RECENT FINDINGS

The benefits of cancer screening in older adults remain unclear due to minimal inclusion of adults > 75 years old in most randomized controlled trials. Indirect evidence suggests that the benefits of screening seen in younger adults (< 70 years old) can be extrapolated to older adults when they have an estimated life expectancy of at least 10 years. However, older adults, especially those with limited life expectancy, may be at increased risk for experiencing harms of screening, including overdiagnosis of clinically unimportant diseases, complications from diagnostic procedures, and distress after false positive test results. We provide a framework to integrate key factors such as health status, risks and benefits of specific tests, and patient preferences to guide clinicians in cancer screening decisions in older adults.

Cervical Cancer Screening among Women Receiving Antiretroviral Therapy in a Resource-Limited Environment

Background:

Cervical cancer is among the most prevalent cancer among women worldwide and women living with HIV are at increased risk, especially in a resource-limited environment.

Objective:

This study aimed to determine levels of awareness, knowledge, uptake, and willingness to screen for cervical cancer among women receiving care in an HIV clinic at Dodoma Regional Referral Hospital (DRRH), Tanzania.

Methods:

Data were collected for a period of three weeks from July 21 to August 11, 2017 using a mobile phone data collection App. A total of 421 Women aged 18-50 years old were included in the study.

Results:

Majority of the women interviewed (n=306, 73%) were aware of cervical cancer. Among those who were aware, 84% (n=257) did not recall ever being screened for cervical cancer, and majority had a poor knowledge of cervical cancer. Educational level completed (p=0.01), income per month (p=0.02), age group (p<0.0001), and area of residence (p<0.0001) were all significantly associated to awareness of cervical cancer. Most of the women who have never screened (n=231, 91%) expressed willingness to be screened. Prior uptake of cervical cancer screening was associated with number of live births (p=0.001) and area of residence (p=0.04). And Willingness to screen was significantly associated with age groups (p=0.03) and the number of live births (p=0.03). Moreover, we found that younger age and urban residence was positively associated with awareness and uptake of cervical cancer screening. Willingness was found to decrease as age increased.

Conclusion:

The study found that despite older women’s higher risk of cervical cancer, those who indicated willingness to screen were younger. Additional education, health promotion, and integration of cervical cancer screening services is needed to improve cervical cancer awareness and screening uptake at the HIV clinic.

Characteristics and Treatments of Patients Aged 65 Years or Over with Cervical Cancer

Purpose

Although the mortality of elderly women with cervical cancer is high, their characteristics and prognosis have not attracted sufficient attention. This study aims to clarify the prognostic factors of cervical cancer patients aged ≥65.

Patient and Methods

The incidences and characteristics of patients diagnosed with cervical cancer (aged ≥65 and <65) during 2004–2015 were obtained through the Surveillance, Epidemiology, and End Results Program (SEER) database. The differences of distributions of characteristics between two age groups were compared by chi-squared (χ²) test. Kaplan–Meier survival method, Log-rank test, Cox-regression and visual nomogram were utilized for survival analysis.

Results

The annual incidences of two age groups with cervical cancer were (5.5–7.5)/100,000 and (3.4–3.9)/100,000, respectively, during 2004–2015. The 1-year and 5-year cancer-specific survival rates of old patients were both lower than those of young patients (P <0.001). The proportions of unmarried state and advanced International Federation of Gynecology and Obstetrics (FIGO) stage in old patients were higher than those in relatively young patients, and fewer elderly patients received surgery. Univariate and multivariate survival analysis showed non-squamous cell carcinoma, poor differentiation and late FIGO stage were independent poor prognostic factors for patients aged ≥65. Treatments improved the outcomes of elderly patients, and the effect of surgery was better than non-surgical treatment on elderly patients with FIGO I. Besides, geriatric score and survival probability could be accomplished by our nomogram with a c-index of 0.7945.

Conclusion

Delayed diagnosis and insufficient treatment were two distinct features of elderly patients and correlated with their poor clinical outcomes. More attention and active treatments should be adopted in elderly women based on their general condition.

Cervical cancer burden in Latin America and the Caribbean: Where are we?

In May 2018, the World Health Organization (WHO) called for the elimination of cervical cancer. To monitor this initiative, we examined cervical cancer incidence and mortality in the Latin America and Caribbean (LAC) region using GLOBOCAN 2018, Cancer Incidence in Five Continents Series, and the WHO Mortality Database. We estimated the number of cases and age-standardized rates (ASRs) for cervical cancer incidence and mortality for 2018. We also presented the ASRs for recorded cervical cancer incidence from the period 2008 to 2012. We calculated annual rates and analyzed trends in cervical cancer incidence and mortality for all ages combined and for the following age groups: 0-29, 30-49, 50-64 and 65+. Finally, we calculated the estimated average annual percentage change in incidence and mortality rates for the past 10 years. In 2018, an estimated 56,000 new cervical cancer cases and 28,000 cervical cancer deaths occurred among women in LAC with great variations between subregions and countries/territories. Overall, trends in cervical cancer incidence and mortality have decreased over the past decade; however, the rates are still above the elimination threshold of 4 per 100,000 in most LAC countries/territories. Despite the encouraging trends observed, achieving the elimination of cervical cancer in the region still requests substantial political commitment and economic effort. Population-based cancer registries are critical in monitoring the elimination initiative.

Comparisons of survivals and toxicities between young and elderly patients with cervical cancer treated with definitive radiotherapy or concurrent chemoradiotherapy

OBJECTIVE

To compare the survivals and toxicities of young and elderly patients with cervical cancer treated with definitive radiotherapy or concurrent chemoradiotherapy (CCRT).

MATERIALS AND METHODS

Patients with cervical cancer treated with radiotherapy or CCRT between January 2010 and December 2015 in our institute were reviewed. A dose of 50.4 Gy in 28 fractions was delivered to the pelvis with intensity modulated radiation therapy. In addition, a dose of 30-36 Gy in 5-7 fractions was prescribed to point A with brachytherapy. Weekly cisplatin was the first-line regimen of concurrent chemotherapy. Comparisons were made between patients in the young group (<60 years) and those in the elderly group (≥70 years) with multivariate analysis and propensity score matching.

RESULTS

There were 991 patients in the young group and 70 patients in the elderly group. The median follow-up period was 30.2 months. In multivariate analysis, age was an independent factor of overall survival (OS, hazard ratio, HR 1.99, p = 0.014), but it was not significant in predicting disease-free survival (DFS, HR 1.41, p = 0.179) and cancer-specific survival (CSS, HR 1.38, p = 0.332). After propensity score matching, 64 pairs of patients were selected. The 3-year OS, DFS, and CSS rates in the young and elderly groups were 86.5% and 73.9% (p = 0.280), 74.6% and 75.4% (p = 0.744), and 87.9% and 81.7% (p = 0.967), respectively. Significant differences between the young and elderly groups were observed in grade 3 and above chronic toxicities (2.9% and 8.6%, p = 0.027) and grade 3 and above chronic gastrointestinal toxicities (2.4% and 8.6%, p = 0.009).

CONCLUSION

After definitive radiotherapy or CCRT, the DFS and CSS of elderly patients with cervical cancer were similar to those in young patients. Elderly patients experienced more chronic toxicities than did young patients.

Benefit of Cisplatin With Definitive Radiotherapy in Older Women With Cervical Cancer

Background: Cisplatin with definitive radiotherapy (RT) is considered the standard of care for cervical cancer; however, older women are frequently undertreated and have worse outcomes compared with younger patients. Because women aged ≥65 years have been disproportionately underrepresented in clinical trials, uncertainties exist regarding how much they benefit from the addition of cisplatin to RT. Patients and Methods: Women aged ≥65 years with nonmetastatic cervical cancer treated with definitive external-beam RT and brachytherapy were identified in the SEER-Medicare database. Death attributable to cervical cancer (cancer-specific mortality [CSM]) was evaluated against competing risks of death using Gray’s test. Propensity score analysis and the Fine-Gray multivariable regression model were used to adjust for baseline differences, including comorbidity. Results: The total cohort comprised 826 patients, of whom 531 (64%) received cisplatin, 233 (28%) were FIGO stage I, 374 (45%) were stage II, and 219 (27%) were stage III–IVA. Older age and chronic kidney disease significantly predicted omission of cisplatin. Virtually all cisplatin dosing was weekly, with a median of 5 cycles. Death from cervical cancer was significantly lower with cisplatin than without (5-year CSM, 31% vs 39%; P=.02; adjusted hazard ratio, 0.72; P=.02), which persisted in propensity score analysis. Receiving ≥5 cycles was required for benefit, as no difference in CSM was seen in patients receiving 1 to 4 cycles versus no cisplatin. Subgroup analyses revealed that the benefit of cisplatin persisted in women aged ≥75 years and those with early-stage disease. Incidence of cytopenia, nausea/vomiting, and hypovolemia increased in patients treated with cisplatin. Conclusions: Administration of cisplatin with definitive RT in women aged ≥65 years was associated with a significant benefit in the incidence of death attributable to cervical cancer, despite competing risks for mortality in an older population. Receiving at least 5 cycles of weekly cisplatin was required for benefit.

Cervical Cancer Incidence Among Elderly Women in Massachusetts Compared With Younger Women

IMPORTANCE

Current cancer screening guidelines recommend cessation of cervical cancer screening at the age of 65 years for most women. To examine residual risk among elderly women, we compared cervical cancer incidence rates (IRs) in Massachusetts from 2004 to 2015 among women younger than 65 years versus 65 years and older.

MATERIALS AND METHODS

The Massachusetts Cancer Registry was used to identify all women diagnosed with cervical cancer between January 01, 2004, to December 31, 2015. Cancer incidence was calculated based on age of diagnosis (<65 years vs ≥65 years).

RESULTS

In Massachusetts, 2,418 incident cases of cervical cancer were diagnosed from 2004 to 2014, of which 571 (23.6%) were diagnosed among women 65 years and older. When compared with women diagnosed younger than 65 years, women diagnosed at the age of 65 years and older were more likely to be diagnosed with stage II or higher (71.8% vs 43.8%, p < .001). Cervical cancer IRs decreased annually for women younger than 65 years from 2004 to 2015. Among women 65 years and older, cancer IRs decreased by 3.9% annually from 2004 to 2013 (p = .0009), but 2013 to 2015 showed an increasing trend (annual percent change + 14.1%, p = .12).

CONCLUSIONS AND RELEVANCE

Women 65 years and older account for one quarter of cervical cancer diagnoses in Massachusetts and present with higher-stage disease than younger women. Upcoming planned revisions in screening and prevention guidelines should address the continued risk of cervical cancer for older women.
