Treatment Strategies for Cervical Cancer in Older Women: Challenges and Advancements

Abstract: Recent advances in brachytherapy (BT) and chemotherapy, as well as consensus statements from several different organizations, were examined in this study as they pertain to the treatment of locally advanced cervical cancer (LACC). Since patients undergoing intensive chemotherapy before, during, and after radiation therapy (RT) experienced significant toxicities, it was decided that no additional conventional therapeutic options should be pursued. The use of PET-CT and MRI in the assessment of pelvic lymph nodes and bone marrow metastases improved pelvic RT planning. It can be concluded from the findings of the study that by administering an integrated boost for metastatic pelvic lymph nodes in IMRT followed by MRI-guided adaptive beam therapy, patients with LACC may benefit from modern radiation therapy methods that treat bladder and rectum tissues while shortening treatment times.

Cervical cancer in older women: Does age matter?

ObjectivesCervical cancer is frequently diagnosed in older women, but few studies have focused on cervical cancer in this specific population. The objectives of this study were to provide an overview of the demographic profile and therapeutic care of women with cervical cancer, and to identify whether age is a prognostic factor. Study designRetrospective population-based study from a gynecological cancer registry in a French Regional University Hospital and Comprehensive Cancer Center. 292 women diagnosed with cervical cancer between January 1, 2005, and December 31, 2015, were included. They were classified into younger women (YW), that is, under 70 years of age (N = 228), and older women (OW), that is, aged 70 years or more (N = 64). Main outcome measuresThe primary outcome was overall survival (OS). Cox proportional hazards models were developed to assess the impact of age on OS. ResultsCompared with YW, larger proportions of OW had comorbidities (14% vs 7% with a score ≥ 2 on the Charlson Comorbidity Index, P <0.001) and more advanced tumors (37.3% vs 19.7% with FIGO IV, P <0.001); the OW group had a lower treatment rate (81.3% vs 95.6%, P <0.001), and a smaller proportion had undergone surgery (37.5% vs 81.7%, P<.001) but a larger proportion had radiotherapy (67.2% vs 49.6%, P = .01). One-year, 5-year and 10-year OS rates were: 91.6%, 74.1% and 63.9% for YW, and 69.9%, 36.4% and 12.3% for OW, respectively (P <0.001). The hazard ratio for death was twice as high in OW compared with YW with cervical cancer (HR = 2.19 [1.41 – 3.40], P <0.001), independently of FIGO stage, histology, and comorbidities. ConclusionsThe prognosis for cervical cancer depends on age. Screening with the G8 tool followed by a comprehensive geriatric assessment could lead to more suitable treatment being offered to older patients.

Association between Metformin Use and Mortality after Cervical Cancer in Older Women with Diabetes.

To examine the association between metformin use and mortality in patients with diabetes and cervical cancer. Using Ontario health databases, a retrospective, population-based cohort study was conducted in women with diabetes ≥ age 66 years diagnosed with cervical cancer between 1997 and 2010. The association between metformin exposure and cervical cancer-specific mortality was examined using Fine-Gray regression models, with noncancer death as a competing risk and cumulative metformin use as a time-varying exposure. The association with overall mortality was examined using Cox regression models. Among the 181 women with diabetes and cervical cancer, there were 129 deaths, including 61 cervical cancer-specific deaths. The median follow-up was 5.8 years (interquartile range 4.2-9.6 years) for surviving patients. Cumulative dose of metformin after cervical cancer diagnosis was independently associated with a decreased risk of cervical cancer-specific mortality and overall mortality in a dose-dependent fashion [HR 0.79; 95% confidence interval (CI), 0.63-0.98; and HR 0.95; 95% CI, 0.90-0.996 per each additional 365 g of metformin use, respectively]. There was no significant association between cumulative use of other antidiabetic drugs and cervical cancer-specific mortality. This study suggests an association between cumulative metformin use after cervical cancer diagnosis and lower cervical cancer-specific and overall mortality among older women with diabetes. Cumulative dose of metformin use after cervical cancer diagnosis among older women with diabetes may be associated with a significant decrease in mortality. This finding has important implications if validated prospectively, as metformin is inexpensive and can be easily combined with standard treatment for cervical cancer.

Cervical cytology and the diagnosis of cervical cancer in older women.

ObjectivesMost non-screen-detected cervical cancers are advanced stage. We assess the potential for cytology to expedite diagnosis when used outside of routine call and recall screening for cervical cancer.MethodsTwo cohorts of women with cytology that did not appear to have been taken as part of routine screening, nested within a census of cervical cytology, in England between April 2007 and March 2010 were studied: 93,322 women aged 40–69 at first cytology, and 14,668 women aged ≥70. The diagnostic performance of high grade cervical squamous intraepithelial lesion (HSIL) or worse cytology was estimated. We also estimated case-fatality from stage distribution in women aged ≥66 with and without cytology in the year prior to diagnosis.ResultsThere were 259 cancers diagnosed in women aged 40–69 at first cytology, and 78 in women aged ≥70. The sensitivity of cytology ≥ HSIL for cancer was 89% and 83% respectively, and the number of women needed to test to identify one cancer was 404 (95% confidence interval [CI]: 355–462) and 226 (95% CI: 177–292) respectively. Women aged ≥66 with cytology within a year of diagnosis had earlier stage cancers than those without, corresponding to a 17–22% reduction in case fatality.ConclusionsCervical cytology is an excellent identifier of cancer among women tested outside routine screening call and recall. Its use as a triage tool, for instance in women with vague gynaecological symptoms, could facilitate earlier stage diagnosis and reduce cervical cancer mortality.

Increased age and race-specific incidence of cervical cancer after correction for hysterectomy prevalence in the United States from 2000 to 2009.

Invasive cervical cancer is thought to decline in women over 65 years old, the age at which cessation of routine cervical cancer screening is recommended. However, national cervical cancer incidence rates do not account for the high prevalence of hysterectomy in the United States. Using estimates of hysterectomy prevalence from the Behavioral Risk Factor Surveillance System (BRFSS), hysterectomy-corrected age-standardized and age-specific incidence rates of cervical cancer were calculated from the Surveillance, Epidemiology, and End Results (SEER) 18 registry in the United States from 2000 to 2009. Trends in corrected cervical cancer incidence across age were analyzed using Joinpoint regression. Unlike the relative decline in uncorrected rates, corrected rates continue to increase after age 35-39 (APC(CORRECTED) = 10.43) but at a slower rate than in 20-34 years (APC(CORRECTED) = 161.29). The highest corrected incidence was among 65- to 69-year-old women, with a rate of 27.4 cases per 100,000 women as opposed to the highest uncorrected rate of 15.6 cases per 100,000 aged 40 to 44 years. Correction for hysterectomy had the largest impact on older, black women given their high prevalence of hysterectomy. Correction for hysterectomy resulted in higher age-specific cervical cancer incidence rates, a shift in the peak incidence to older women, and an increase in the disparity in cervical cancer incidence between black and white women. Given the high and nondeclining rate of cervical cancer in women over the age of 60 to 65 years, when women are eligible to exit screening, risk and screening guidelines for cervical cancer in older women may need to be reconsidered.

Risk Factors and Other Epidemiologic Considerations for Cervical Cancer Screening: A Narrative Review for the U.S. Preventive Services Task Force

Despite the success of cervical cancer screening programs, questions remain about the appropriate time to begin and end screening. This review explores epidemiologic and contextual data on cervical cancer screening to inform decisions about when screening should begin and end. Cervical cancer is rare among women younger than 20 years. Screening for cervical cancer in this age group is complicated by lower rates of detection and higher rates of false-positive results than in older women. Methods used to diagnose and treat cervical intraepithelial neoplasia have important potential adverse effects. High-risk human papillomavirus infections and abnormalities on cytologic and histologic examination have relatively high rates of regression. Accordingly, cervical cancer screening in women younger than 20 years may be harmful. The incidence of, and mortality rates from, cervical cancer and the proportion of U.S. women aged 65 years or older who have had a Papanicolaou smear within 3 years have decreased since 2000. Available evidence supports discontinuation of cervical cancer screening among women aged 65 years or older who have had adequate screening and are not otherwise at high risk. Further reductions in the burden of cervical cancer in older women are probably best achieved by focusing on screening those who have not been adequately screened.

Human papilloma virus (HPV) prophylactic vaccination: Challenges for public health and implications for screening

Prophylactic vaccination against high risk human papilloma virus (HPV) 16 and 18 represents an exciting means of protection against HPV related malignancy. However, this strategy alone, even if there is a level of cross protection against other oncogenic viruses, cannot completely prevent cervical cancer. In some developed countries cervical screening programmes have reduced the incidence of invasive cervical cancer by up to 80% although this decline has now reached a plateau with current cancers occurring in patients who have failed to attend for screening or where the sensitivity of the tests have proved inadequate. Cervical screening is inevitably associated with significant anxiety for the many women who require investigation and treatment following abnormal cervical cytology. However, it is vitally important to stress the need for continued cervical screening to complement vaccination in order to optimise prevention in vaccinees and prevent cervical cancer in older women where the value of vaccination is currently unclear. It is likely that vaccination will ultimately change the natural history of HPV disease by reducing the influence of the highly oncogenic types HPV 16 and 18. In the long term this is likely to lead to an increase in recommended screening intervals. HPV vaccination may also reduce the positive predictive value of cervical cytology by reducing the number of truly positive abnormal smears. Careful consideration is required to ensure vaccination occurs at an age when the vaccine is most effective immunologically and when uptake is likely to be high. Antibody titres following vaccination in girls 12–16 years have been shown to be significantly higher than in older women, favouring vaccination in early adolescence prior contact with the virus. Highest prevalence rates for HPV infection are seen following the onset of sexual activity and therefore vaccination would need to be given prior to sexual debut. Since 20% of adolescents are sexually active at the age of 14 years, vaccination has been suggested at 10–12 years. However, parental concerns over the sexual implications of HPV vaccination may reduce uptake of vaccination thereby reducing the efficacy of an HPV vaccination programme. Concerns have already been raised over the acceptability of a vaccine preventing a sexually transmitted infection in young adolescents, particularly amongst parents or communities who consider their children to be at low risk of infection. This may be a particularly sensitive issue for ethnic minority groups. This paper considers the factors which will influence the efficacy of a public HPV vaccination programme and its impact on cervical screening.

Cervical cancer in older women: A molecular analysis of human papillomavirus types, HLA types, and p53 mutations

OBJECTIVE: The purpose of this study was to evaluate cervical cancers in older women to determine whether they differed from tumors in younger women with respect to human papillomavirus types, frequencies of p53 mutations, and presence of a proposed high-risk HLA-DR2 haplotype. STUDY DESIGN: Cervical tissue was obtained from women undergoing surgical treatment of in situ or invasive carcinoma of the cervix. Viral and genomic deoxyribonucleic acid was extracted. The presence of human papillomavirus deoxyribonucleic acid was detected by polymerase chain reaction amplification. Viral subtypes were assigned by means of a combination of type-specific amplification and automated sequencing of the L1 region. The presence of p53 mutations was evaluated by direct sequencing of exons 5 through 9. The HLA-DR locus was screened for the presence of the high-risk DRB1*1501 allele by means of selective polymerase chain reaction amplification followed by agarose gel electrophoresis of HLA-DR2 types. RESULTS: Tumors from 39 women 62 to 85 years old were analyzed. Tumors from 104 younger women formed a reference group. Human papillomavirus 16 was found in 41% and 54% and human papillomavirus 18 was found in 10% and 12% of the tissue samples from older and younger women, respectively. The overall distributions of human papillomavirus types did not differ statistically between the groups. One of the 25 older patients tested had a p53 mutation. This tumor also had a positive test result for human papillomavirus 18. The DR*1501 allele was present in 33% of the older patients and 28% of the younger patients. The expected frequency of this allele in white Americans is 19.8%. The increased frequency of this allele among both older and younger women with cervical cancer was statistically significant ( P < .05). CONCLUSIONS: We hypothesized that cervical cancer in older women might differ from that in younger women with respect to human papillomavirus types, natural host immunity, or the frequency of nonviral origins of the cancer. The findings show, however, that tumors from older women are extremely similar to those from younger women with respect to the human papillomavirus types present and the infrequent occurrence of p53 mutations. In addition we found that an HLA-DR allele that is associated with a risk of cervical cancer in younger women is also associated with risk in older women. These findings are most consistent with a model similar to that in younger women but with an unusually long latency for the transforming effect of the virus in some hosts.

Low efficiency of cytologic screening for cancer in situ of the cervix in older women

Cytologic screening for cervical cancer has proven to be beneficial in many countries, although the value of this intervention in women older than 50 years remains controversial. The purpose of this study was to investigate the efficiency of detecting cancer in situ by means of a cytologic smear at different ages, with special emphasis on the benefit of screening in women above the age of 50. We analyzed 466,275 smears taken in an open cohort of 118,890 women in Sweden between 1969 and 1988. The number of cancers in situ detected per 1,000 smears, the detection ratio, was used as an outcome measure in univariate analyses and in multivariate regression models. Cancer in situ was detected in 1,076 women in the study cohort. The detection ratio peaked at ages 30 to 34 and decreased heavily during the next 15 years of age. The efficiency of taking smears at ages above 50 was only 20 per cent (OR, 0.19; 95% CI, 0.14-0.26) of that at ages 30 to 34. These results were not changed when adjusting for time period and time interval since the previous smear. In spite of a high incidence of invasive cervical cancer in older women, the benefit of cytologic screening to detect cancer in situ above the age of 50 is uncertain.

Increasing mortality from cancer of the cervix in young Australian women.

Mortality from uterine cancer in Australia has fallen progressively since 1908, as has mortality from cancer of the cervix specifically since it was distinguished, in statistics, from other uterine cancer in 1950. However, in women aged under 40 years, this trend has reversed recently, and cervical cancer mortality has risen since about 1970. This rise has also been shown by incidence data collected by the New South Wales Central Cancer Registry. Similar increases have been observed in New Zealand, Britain at least, appear to parallel increases in promiscuous sexual activity. Increases in the frequency of cervical cancer in older women can be expected when the cohorts affected (those born after 1935) reach older age groups.
