About this study
Official title: In Situ/Microinvasive Adenocarcinoma of the Uterine Cervix and HPV-type Impact: Pathologic Features, Treatment Options, and Follow-up Outcomes - Cervical Adenocarcinoma Study Group (CAS-Group).
The present study will mainly aim to review and characterize the pathologic features, treatment options, and follow-up outcomes of women with in situ/microinvasive adenocarcinoma of the uterine cervix according to HPV status (positive versus negative high-risk HPV). It will evaluate the impact of HPV status on the recurrence and survival during a follow-up of five years. The present study will be a multi-institutional study including several oncological Italian Centers. Data will be retrospectively collected from January 2012 to December 2016 with a total follow-up of 5 years.
Read the detailed description
The incidence of cervical cancer in developed countries declined considerably in the last few decades. This has been possible for efficient screening programs to which HPV vaccines have been added over the past 15 years. Despite this global reduction in cervical lesions, the incidence of adenocarcinoma of the uterine cervix (AC) increases in invasive and in situ stages. This increase mainly affects women aged 30-40, with an incidence of 11.2 per 100.000 women. On the contrary, the squamous histological lesions revealed an increase in the incidence of in situ lesions and a concomitant reduction of invasive stages. These data would seem to suggest a delay in the diagnosis of cervical glandular lesions, a shorter interval of disease progression from the adenocarcinoma in situ (AIS) to infiltrating stages, or a different process of carcinogenesis.
Most glandular cervical lesions occur at an early stage. The standard of treatment for in situ or micro-invasive lesions is extra fascial hysterectomy (AIS or stage 1A1 with no LVSI) or modified radical hysterectomy with pelvic lymph node dissection (stage 1A1 with LVSI, or 1A2). In fertility-sparing treatment, conization or radical trachelectomy with pelvic lymph node dissection is an option.
Another aspect that differentiates cervical adenocarcinoma from squamous lesions is the link with HPV infection. In 2018, the International Endocervical Criteria and Classification categorized cervical glandular lesions into HPV-associated and non-HPV-associated AC. Unlike cervical squamous lesions, which are almost all linked to high-risk HPV types, AC can be HPV negative in up to 15-20% of cases. The HPV 18 genotype is the most represented in AC with a rate of 38-50% in AIS and 50% in invasive stages. Based on some studies, it appears that non-HPV-related lesions have worse outcomes. This can significantly impact screening programs where 14 high-risk HPVs are tested.
In a recent study including 341 surgical specimens of AC, 100% of non-HPV-related lesions were classified as Silva Pattern C (the worst prognostic pattern). Instead, no impact of the HPV genotype was found on 113 women with AC during a follow-up of 5 years. HPV 45 showed a shorter 5-year survival than HPV 16 or 18.
While for advanced lesions, the stage itself represents the most important prognostic factor for prognosis, in situ or micro-invasive lesions may represent the best target for evaluating HPV status impact. This may be of interest as there is the option of conservative treatment in addition to standard treatment in early stages.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The present study will mainly aim to review and characterize the pathologic features, treatment options, and follow-up outcomes of women with in situ/microinvasive adenocarcinoma of the uterine cervix according to HPV status (positive versus negative high-risk HPV). It will evaluate the impact of HPV status on the recurrence and survival during a follow-up of five years. The present study will be a multi-institutional study including several oncological Italian Centers. Data will be retrospectively collected from January 2012 to December 2016 with a total follow-up of 5 years.
Detailed description
The incidence of cervical cancer in developed countries declined considerably in the last few decades. This has been possible for efficient screening programs to which HPV vaccines have been added over the past 15 years. Despite this global reduction in cervical lesions, the incidence of adenocarcinoma of the uterine cervix (AC) increases in invasive and in situ stages. This increase mainly affects women aged 30-40, with an incidence of 11.2 per 100.000 women. On the contrary, the squamous histological lesions revealed an increase in the incidence of in situ lesions and a concomitant reduction of invasive stages. These data would seem to suggest a delay in the diagnosis of cervical glandular lesions, a shorter interval of disease progression from the adenocarcinoma in situ (AIS) to infiltrating stages, or a different process of carcinogenesis.
Most glandular cervical lesions occur at an early stage. The standard of treatment for in situ or micro-invasive lesions is extra fascial hysterectomy (AIS or stage 1A1 with no LVSI) or modified radical hysterectomy with pelvic lymph node dissection (stage 1A1 with LVSI, or 1A2). In fertility-sparing treatment, conization or radical trachelectomy with pelvic lymph node dissection is an option.
Another aspect that differentiates cervical adenocarcinoma from squamous lesions is the link with HPV infection. In 2018, the International Endocervical Criteria and Classification categorized cervical glandular lesions into HPV-associated and non-HPV-associated AC. Unlike cervical squamous lesions, which are almost all linked to high-risk HPV types, AC can be HPV negative in up to 15-20% of cases. The HPV 18 genotype is the most represented in AC with a rate of 38-50% in AIS and 50% in invasive stages. Based on some studies, it appears that non-HPV-related lesions have worse outcomes. This can significantly impact screening programs where 14 high-risk HPVs are tested.
In a recent study including 341 surgical specimens of AC, 100% of non-HPV-related lesions were classified as Silva Pattern C (the worst prognostic pattern). Instead, no impact of the HPV genotype was found on 113 women with AC during a follow-up of 5 years. HPV 45 showed a shorter 5-year survival than HPV 16 or 18.
While for advanced lesions, the stage itself represents the most important prognostic factor for prognosis, in situ or micro-invasive lesions may represent the best target for evaluating HPV status impact. This may be of interest as there is the option of conservative treatment in addition to standard treatment in early stages.

The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall recurrence at 5 year in HPV positive vs HPV negative women (time frame: At 5 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
