Cervical cancer screening is one of the most significant public health accomplishments of the 20th century. Over the last 50 years, incidence and mortality rates from cervical cancer in the US have decreased by more than 50%1 because of widespread use of the Papanicolaou test and later adoption of high-risk human papillomavirus (hrHPV) testing.

Regular screening is critical in detecting disease because women with precancerous cervical intraepithelial neoplasia or early-stage cervical cancer are often asymptomatic. When detected early, 5-year cervical cancer survival is higher than 90%.1 Yet more than half of all cervical cancer diagnoses are made beyond an early stage; 37% when cancer has spread regionally to local lymph nodes and 15% when there are distant cancer metastases. Five-year survival is just 20% for women diagnosed with metastatic disease.1

Cervical cytology (Papanicolaou test) and hrHPV tests are highly effective in detecting early, more treatable disease; however, these modalities are only beneficial for women who undergo recommended screening. Unfortunately, about half of all women diagnosed with cervical cancer have never been screened or are not up-to-date on screening,2 and these women are more likely to present with regional or distant metastatic disease. Overall, approximately 1 in 4 women in the US are not up-to-date on cervical cancer screening.3 Women living in poverty or having fewer years of formal education have even lower screening rates. The direct link between screening and survival illustrates a clear and urgent need to improve cervical cancer screening rates in the US; new self-collection options approved by the US Food and Drug Administration (FDA) provide an opportunity to do so.

Screening for Lung Cancer US Preventive Services Task Force Recommendation Statement

Author/s: 
US Preventive Services Task Force

Importance: Lung cancer is the second most common cancer and the leading cause of cancer death in the US. In 2020, an estimated 228 820 persons were diagnosed with lung cancer, and 135 720 persons died of the disease. The most important risk factor for lung cancer is smoking. Increasing age is also a risk factor for lung cancer. Lung cancer has a generally poor prognosis, with an overall 5-year survival rate of 20.5%. However, early-stage lung cancer has a better prognosis and is more amenable to treatment.

Objective: To update its 2013 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a systematic review on the accuracy of screening for lung cancer with low-dose computed tomography (LDCT) and on the benefits and harms of screening for lung cancer and commissioned a collaborative modeling study to provide information about the optimum age at which to begin and end screening, the optimal screening interval, and the relative benefits and harms of different screening strategies compared with modified versions of multivariate risk prediction models.

Population: This recommendation statement applies to adults aged 50 to 80 years who have a 20 pack-year smoking history and currently smoke or have quit within the past 15 years.

Evidence assessment: The USPSTF concludes with moderate certainty that annual screening for lung cancer with LDCT has a moderate net benefit in persons at high risk of lung cancer based on age, total cumulative exposure to tobacco smoke, and years since quitting smoking.

Recommendation: The USPSTF recommends annual screening for lung cancer with LDCT in adults aged 50 to 80 years who have a 20 pack-year smoking history and currently smoke or have quit within the past 15 years. Screening should be discontinued once a person has not smoked for 15 years or develops a health problem that substantially limits life expectancy or the ability or willingness to have curative lung surgery. (B recommendation) This recommendation replaces the 2013 USPSTF statement that recommended annual screening for lung cancer with LDCT in adults aged 55 to 80 years who have a 30 pack-year smoking history and currently smoke or have quit within the past 15 years.
