Materials and Methods
The National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database was utilized. SEER is a population-based cancer registry that includes approximately 26% of the US population.22 SEER is composed of a number of geographically distinct tumor registries. The demographic characteristics of the SEER registries have been previously characterized and reported.23 Data from SEER 17 registries was utilized. The study received approval from the Columbia University Institutional
Results
A total of 3987 women including 988 with adenocarcinomas (24.8%) and 2999 with squamous cell carcinomas with microinvasive disease (75.2%) were identified. The demographic and clinical variables of the cohort are displayed in Table 1. Stage IA1 tumors were noted in 554 of the women with adenocarcinomas (56.1%) and in 1610 of those with squamous neoplasms (53.7%), whereas 43.9% of women with adenocarcinomas and 46.3% of those with squamous cell carcinomas had stage IA2 tumors (P = .19). Women
Comment
Our analysis suggests 2 major findings for microinvasive cervical cancer. First, outcomes are similar for squamous cell carcinomas and adenocarcinomas. Second, conservative fertility-preserving treatment appears to be safe for women with stage IA1 and IA2 adenocarcinomas.
Given the concern that adenocarcinomas are associated with an inferior prognosis, prior staging systems have not acknowledged microinvasive adenocarcinomas as an entity. In contrast, most studies have suggested that women with

2019, Gynecologic OncologyCitation Excerpt :The objective in early stage of cervical cancer is therefore to reduce the risk for treatment-related morbidity e.g. offering fertility-sparing treatment. Hence, conisation is standard of care in stage IA1 [8–10], but in our study only one third of patients were treated accordingly. Instead simple hysterectomy was frequently performed.

2019, Critical Reviews in Oncology/HematologyCitation Excerpt :Diagnostic imaging techniques, such as computed tomography [CT], magnetic resonance [MR], and eventually positron emission tomography [PET]/CT, should be used for an adequate staging at presentation, especially in patients with apparently locally advanced disease (National Cancer Comprehensive Network, 2019). Several studies on surgically- treated patients with stage Ia-IIa cervical cancer failed to detect different oncologic outcomes between adenocarcinoma and squamous cell carcinoma (Ruengkhachorn et al., 2016; Look et al., 1996; Harrison et al., 1993; Shingleton et al., 1995; Spoozak et al., 2012; Winer et al., 2015). Conversely, other investigations on patients with early stage disease who underwent primary radical hysterectomy with or without adjuvant radiotherapy or concurrent chemoradiation, reported a poorer disease-free survival [DFS] and overall survival [OS] for adenocarcinoma compared with squamous cell carcinoma (Irie et al., 2000; Nakanishi et al., 2000; Noh et al., 2014; Landoni et al., 1997; Hopkins and Morley, 1991; Park et al., 2010).
