Excisional procedures have a central role in the management of adenocarcinoma in situ of the cervix (AIS). We aimed to evaluate the relationship between the excisional specimen dimensions and the endocervical margin status. We conducted a multicentric retrospective study in seven French centers. All cases with proven AIS on a colposcopic biopsy and undergoing an excisional procedure afterwards were included in the analysis. We evaluated the impact of excision length, along with the lateral and anteroposterior diameters on the endocervical margin status. An additional subgroup analysis of the impact of maternal age on endocervical margin status was also conducted. Of the 101 cases of AIS diagnosed on initial biopsy, 95 underwent a primary excisional procedure, among which 80% (n=76/95) had uninvolved endocervical margins and 20% (n=19/95) had positive endocervical margins. The excisional specimen length was not significantly related to the endocervical margin status. Conversely, both lateral and antero-posterior diameters were significantly correlated with the negative endocervical margins status: OR = 1,19, 95% CI [1.03, 1.40], p=0.025, for the lateral diameter and OR = 1.34, 95% CI [1.14, 1.64], p=0.001 for the antero-posterior diameter. The median lateral diameter was 20 mm, IQR (18, 24) in case of endocervical negative margins vs. 18 mm IQR (15, 24) in case of positive endocervical margins (p=0.039), and the median anteroposterior diameter was 17 mm IQR (15, 20) in case of negative endocervical margins vs 14 mm IQR (11, 15) in case of positive endocervical margins (p=0.004), respectively. Additionally, in patients over 45 years old, endocervical margin were more likely to be positive despite similar excisional dimensions (7/17 (41%) of positive endocercival margins before 45 years old vs 12/78 (15%) after, p = 0.039) Endocervical margin statues were significantly related to the transverse diameters (lateral and anteroposterior diameters), but not to the excision specimen length. Reducing the excised length may lead to fewer post-procedure complications but would still allow to obtain a large proportion of negative endocervical margins.

Abstract Internationally, little consensus exists about the best treatment for cervical adenocarcinoma in situ (AIS). This study aimed to determine the incidence of recurrent high‐grade cervical dysplasia and development of local cervical cancer after treatment for AIS. This nationwide, retrospective cohort study included patients with AIS, who were treated by a large loop excision of the transformation zone (LLETZ), cold‐knife conization (CKC), or hysterectomy between January 1, 1990 and December 31, 2021 in the Netherlands. Pathology reports were retrieved from the Dutch Nationwide Pathology Databank (Palga). Primary outcomes were the cumulative incidences of high‐grade cervical dysplasia (cervical intraepithelial neoplasia grade 2 or 3, and AIS) and local cervical cancer up to 20 years after primary treatment. In total, 4243 patients with AIS were included. The primary treatment was a LLETZ, CKC, or hysterectomy in 1593, 2118, and 532 patients, respectively. The incidence of recurrent high‐grade cervical dysplasia after LLETZ (10.5%; 95%CI: 8.6–12.3) was higher than after CKC (5.5%; 95%CI: 4.4–6.6, p &lt;.0001). When a radical excision, that is, surgical margins free of dysplasia at end of treatment, was achieved, the incidence of recurrent high‐grade dysplasia and local cervical cancer did not differ between LLETZ (5.6% [95%CI: 3.3–7.9] and 1.9% [95%CI: 0–4.4]) and CKC (4.7% [95%CI: 3.5–5.8], p = .631 and 1.5% [95%CI: 0.7–2.3], p = .918). After hysterectomy, none of the patients developed cervical dysplasia or local cervical cancer. Conservative treatment for AIS can be considered a safe and final treatment modality when a radical excision is achieved.

Objective: The aim of this study was to determine the efficiency and indications of cold knife conization in the treatment of high-grade cervical lesions. Materials and Methods: This study included patients with high-grade cervical lesions treated with cold knife conization (CKC) within 9 years. Histopathological correlation analyses were carried out among the smear, colposcopic biopsy (CBx), CKC results, and total hysterectomy specimens available. Results: One hundred thirty-one cold knife cone biopsy cases were analyzed for this study. The most common pathology was cervical intraepithelial neoplasia (CIN) II–III, with a frequency of 64 (48.9%). Other conization results in order of frequency were as follows: CIN I at a rate of 29 (22.1%), Carcinoma (Ca) at 19 (14.5%), cervicitis at 14 (10.7%), and negative results at 5 (3.8%). Conclusions: CKC remains an acceptable option in the treatment of CIN and microinvasive carcinoma of the cervix, and the excellent diagnostic and therapeutic efficacy of CKC is well-known and confirmed. When properly performed, the procedure has a low risk of complications and provides an accurate histological representation of the disease process. It is also curative in most cases. Of course, excellent clinical results still require careful, long-term, and attentive follow-up.
