Abstract
Objectives:
We are reporting the evaluation of an opportunistic point of care cervical cancer
screening initiative in Pune, India using a mobile screening unit (MSU).
Methods:
We conducted 290 cervical cancer screening outreach clinics in the MSU. Screening
was performed by trained nurses/ health care providers using visual inspection with
5% acetic acid (VIA). Screen positive women when eligible were treated by thermal
ablation during the same sitting. Women with large lesions not eligible for treatment
with thermal ablation were referred for colposcopy and treatment.
Results:
A total of 10, 925 women were screened between Nov 2016 and June 2019 in 290 outreach
clinics in the MSU. The overall screen positivity was 6.6% (95% CI 6.1, 7.0) with
a declining trend over time. A total of 304/717 (42.4%, 95% CI 38.7, 46.1) women received
treatment with thermal ablation. About 3.6% (11/304) reported minor side effects and
1.6% (5/304) reported lower abdominal pain and all of them subsided after treatment.
Among the 413 women who were advised colposcopy, only 84 (20.33%) women underwent
the procedure. Of these 84 women, 64 (76.19%) had normal colposcopy/ histopathology,
7 (8.33%) had CIN1, 2 (2.38%) had CIN 2, 9 (10.71%) had CIN 3 disease and 2 (2.38%)
women were diagnosed with invasive cancer.
Conclusion:
MSUs are useful for providing cervical cancer screening services, using the ‘screen
and treat’ strategy. Thermal ablation is safe in the field clinics. Additional efforts
are needed to improve the compliance for referral of those with large lesions requiring
additional visits.
Summary Background The knowledge that persistent human papillomavirus (HPV) infection is the main cause of cervical cancer has resulted in the development of prophylactic vaccines to prevent HPV infection and HPV assays that detect nucleic acids of the virus. WHO has launched a Global Initiative to scale up preventive, screening, and treatment interventions to eliminate cervical cancer as a public health problem during the 21st century. Therefore, our study aimed to assess the existing burden of cervical cancer as a baseline from which to assess the effect of this initiative. Methods For this worldwide analysis, we used data of cancer estimates from 185 countries from the Global Cancer Observatory 2018 database. We used a hierarchy of methods dependent on the availability and quality of the source information from population-based cancer registries to estimate incidence of cervical cancer. For estimation of cervical cancer mortality, we used the WHO mortality database. Countries were grouped in 21 subcontinents and were also categorised as high-resource or lower-resource countries, on the basis of their Human Development Index. We calculated the number of cervical cancer cases and deaths in a given country, directly age-standardised incidence and mortality rate of cervical cancer, indirectly standardised incidence ratio and mortality ratio, cumulative incidence and mortality rate, and average age at diagnosis. Findings Approximately 570 000 cases of cervical cancer and 311 000 deaths from the disease occurred in 2018. Cervical cancer was the fourth most common cancer in women, ranking after breast cancer (2·1 million cases), colorectal cancer (0·8 million) and lung cancer (0·7 million). The estimated age-standardised incidence of cervical cancer was 13·1 per 100 000 women globally and varied widely among countries, with rates ranging from less than 2 to 75 per 100 000 women. Cervical cancer was the leading cause of cancer-related death in women in eastern, western, middle, and southern Africa. The highest incidence was estimated in Eswatini, with approximately 6·5% of women developing cervical cancer before age 75 years. China and India together contributed more than a third of the global cervical burden, with 106 000 cases in China and 97 000 cases in India, and 48 000 deaths in China and 60 000 deaths in India. Globally, the average age at diagnosis of cervical cancer was 53 years, ranging from 44 years (Vanuatu) to 68 years (Singapore). The global average age at death from cervical cancer was 59 years, ranging from 45 years (Vanuatu) to 76 years (Martinique). Cervical cancer ranked in the top three cancers affecting women younger than 45 years in 146 (79%) of 185 countries assessed. Interpretation Cervical cancer continues to be a major public health problem affecting middle-aged women, particularly in less-resourced countries. The global scale-up of HPV vaccination and HPV-based screening—including self-sampling—has potential to make cervical cancer a rare disease in the decades to come. Our study could help shape and monitor the initiative to eliminate cervical cancer as a major public health problem.

Emmanuela Gakidou and colleagues find that coverage of cervical cancer screening in developing countries is on average 19% compared to 63% in developed countries.
Cervical screening and human papillomavirus (HPV) vaccination have been implemented in most high-income countries; however, coverage is low in low-income and middle-income countries (LMICs). In 2018, the Director-General of WHO announced a call to action for the elimination of cervical cancer as a public health problem. WHO has called for global action to scale-up vaccination, screening, and treatment of precancer, early detection and prompt treatment of early invasive cancers, and palliative care. An elimination threshold in terms of cervical cancer incidence has not yet been defined, but an absolute rate of cervical cancer incidence could be chosen for such a threshold. In this study, we aimed to quantify the potential cumulative effect of scaled up global vaccination and screening coverage on the number of cervical cancer cases averted over the 50 years from 2020 to 2069, and to predict outcomes beyond 2070 to identify the earliest years by which cervical cancer rates could drop below two absolute levels that could be considered as possible elimination thresholds-the rare cancer threshold (six new cases per 100 000 women per year, which has been observed in only a few countries), and a lower threshold of four new cases per 100 000 women per year.
