Should ovaries be removed or not in early-stage cervical adenocarcinoma: a multicenter retrospective study of 105 patients

Unilateral ovarian recurrence 5 years after hysterectomy for microinvasive squamous cervical cancer stage IA1: a rare case report

BACKGROUND

Ovarian metastasis or recurrence of cervical microinvasive squamous cell carcinoma (SCC) is very rare. We report a case of unilateral ovarian recurrence 5 years after hysterectomy for the SCC stage IA1 without lymph vascular space invasion (LVSI).

CASE PRESENTATION

A 49-year-old female patient suffered from a dull pain in the left lower abdomen for 3 months. And five years ago, she received a laparoscopic hysterectomy for the treatment of stage IA1 (without LVSI) SCC of the cervix. The level of squamous cell carcinoma antigen (SCC-Ag) in serum was significantly elevated (10.60 ng/mL). Pelvic magnetic resonance imaging (MRI) revealed a left ovarian solid tumor measuring 5.5 × 3.9 × 5.6 cm with heterogeneous enhancement. During laparotomy, the left ovarian tumor was measured about 5.0 × 4.5 × 3.0 cm and seemed densely adherent to the posterior peritoneal wall, including the left ureter. The tumor and pelvic lymph node were carefully removed. Postoperative anatomy revealed a solid mass with a greyish-white section. Postoperative pathology showed recurrent moderately differentiated ovarian SCC with negative pelvic lymph nodes. Immunohistochemistry showed that the tumor cells were positive for P16, P63, P40, and CK5/6 markers, and the positive rate of Ki67 was about 80%.

CONCLUSIONS

Ovary preservation is reasonable and appropriate in young patients with microinvasive SCC. Ovarian recurrence is rare, but gynecological oncologists should not overlook its possibility. The serum SCC-Ag is an important indicator for monitoring postoperative disease progression.

PTEN Loss and ARID1A Mutation in an HPV-positive Metastatic Adenocarcinoma Diagnosed Almost 18 yr After an Intact Cone Excision for Endocervical Adenocarcinoma In Situ

There have been previous reports of neoplasms with the morphology of endocervical adenocarcinoma in situ (AIS) that secondarily involve the ovaries, presumably through transtubal spread, with a smaller subset metastasizing to distant sites. These ovarian metastases have been discovered up to 7 yr postexcision of the endocervical lesion, consistent with the known potential for overtly invasive cervical carcinomas to recur late after primary curative management. Herein, we present a case of a premenopausal woman with a pelvic mass classified as metastatic human papillomavirus (HPV)-associated endocervical adenocarcinoma (p16-block immunoreactive, high-risk HPV positive by in situ hybridization with PTEN loss, ARID1A, and PBRM1 mutations detected by qualitative next-generation sequencing), identified 17.7 yr (212 mo) after a fertility-sparing cone excision with negative margins for endocervical AIS [HPV-associated, p16-block immunoreactive; PTEN, and BAF250a (ARID1a) expression retained]. Our case highlights: (1) the potential for a subset of lesions with the morphology of AIS to metastasize, and the extraordinarily long timeframe (almost 18 y, the longest reported to date) during which metastases may still be identified; (2) alterations in PTEN and ARID1A may play a role in the progression of a subset of endocervical carcinomas; and (3) the need for studies to evaluate the utility of incorporating ovarian/pelvic imaging into surveillance protocols following fertility-sparing excisions or ovarian-preserving hysterectomies, during the management of endocervical adenocarcinomas, as well as the need to counsel patients about the small but real risk of delayed discovery of ovarian metastases following fertility-preserving surgeries for AIS.

Clinical, Morphologic, and Molecular Features Associated With Ovarian Metastases From Pattern A Endocervical Adenocarcinomas

Ovarian metastases from endocervical adenocarcinomas (EAs) are rare but well-described. Silva Pattern A tumors have been reported to pose essentially no risk of lymph node metastases or recurrence. We describe a cohort of patients with Silva Pattern A EAs with ovarian metastases, as well as involvement of other sites. Eight pattern A EAs with ovarian metastases (4 synchronous, 4 metachronous) were identified from our institution's pathologic archives (2008-2021). Clinicopathologic and molecular features for each case were recorded. All patients were treated by hysterectomy; in each case, the entire tumor was submitted for histologic evaluation. The synchronous metastases were all clinically suspected to be ovarian primary tumors; EAs with metachronous ovarian involvement were confined to the uterus at initial diagnosis, with ovarian metastasis occurring 5 to 171 months after hysterectomy. Morphologically, all tumors were predominantly gland-forming, 5/8 (63%) displayed prominent mucinous differentiation, and 5/8 (63%) involved the corpus. All EAs were either noninvasive (exophytic/papillary/more complex than adenocarcinoma in situ) or showed nondestructive cervical stromal invasion to a depth of 5 mm or less. In the 5 tumors tested by next-generation sequencing, ARID1A, GNAS, and KRAS mutations were detected in 2 (40%), 3 (60%), and 4 (80%) cases, respectively. All 6 patients with follow-up (range, 32 to 181 mo; median, 99.5 mo) had at least 1 recurrence. All but one are without evident disease at last clinical assessment. In an otherwise typical Silva Pattern A EA, corpus involvement, mucinous differentiation, and certain gene mutations may be associated with risk for synchronous or metachronous ovarian metastases.

Factors Affecting Survival Outcome After Percutaneous Nephrostomy as Palliative Urinary Diversion in Obstructive Uropathy due to Advance Cervical Cancer Patients

Introduction:

Cervical cancer is the 3^rd most common cancer in women. In late stages, obstructive uropathy due to mass infiltration is common and the mainstay of treatment for this condition is palliative urinary diversion through percutaneous nephrostomy. Nevertheless, complications due to nephrostomy may have adverse effects on some patients. Further study is necessary to determine whether nephrostomy is suitable for all cervical cancer patients with obstructive uropathy. This study aims to identify the determinants of survival rate of cervical cancer patients undergoing nephrostomy for obstructive uropathy and determine the group of cervical cancer patients that would benefit the most from nephrostomy.

Methods:

Data were obtained from medical records of cervical cancer patients in Hasan Sadikin Central Public Hospital from January 2018 to December 2019. Log-rank analysis was performed to assess the survival rate of patients based on clinical conditions (age, metastasis, and ECOG performance status) and initial laboratory results (hemoglobin, leukocyte, thrombocyte and blood acidity).

Results:

A total of 163 cases were identified from the medical records, with a median survival of 5(1-17) months. The results of the analysis showed that the survival rates of cervical cancer patients undergoing nephrostomy were significantly affected by age (p = 0.0001), metastasis (p = 0.0001), and ECOG performance status (p = 0.0001), while laboratory findings were not significant factors affecting survival (pHb=0.501; pLeu=0.634; pTr=0.077; pBGA=0.687).

Conclusion:

The survival after nephrostomy in advanced cervical cancer patients is largely affected by age, metastasis, and performance status. The choices of doing nephrostomy in those patients should be considering those factors to maximize the benefit over the risk of complications.

Clear Cell Adenocarcinoma of Uterine Cervix: A Single Institution Retrospective Experience

Purpose

The purpose of the study is to summarize the clinical characteristics and identify the prognosis of clear cell adenocarcinoma of the uterine cervix (CCAUC) in patients without a history of diethylstilbestrol (DES) exposure.

Methods

Forty-two patients with CCAUC, treated initially at Sun Yat-sen University Cancer Center between 1985 and 2017, were studied.

Results

Of all the CCAUC patients, the median age was 47 years old, and the median tumor size was 3 cm. Thirty-four early stage patients (IB = 28, IIA = 6) underwent radical surgery. Eight advanced stage patients (IIB = 8) received concurrent chemoradiotherapy (n = 4) or radical surgery (n = 4). Survival analysis showed that patients with early stage (IB-IIA) had a significantly better 5-year progression-free survival (PFS) and overall survival (OS) than those with advanced stage (IIB) (p < 0.05). The patients with negative pelvic lymph node (PLN) had a significantly better 5-year PFS and OS than those with positive PLN (p < 0.05). Radiotherapy (RT) did not affect PFS or OS in early stage patients with intermediate risk factors (p > 0.05). Adjuvant chemotherapy (CT) did not affect PFS or OS in early stage patients without risk factors (p > 0.05).

Conclusion

The FIGO stage and pelvic node status were important prognostic factors for both PFS and OS. For treatment modality, we recommended that radical surgery alone was used in early stage patients without high risk factors. Ovarian preservation in early stage patients involved some risk.

Diagnosis and Management of Adenocarcinoma in Situ: A Society of Gynecologic Oncology Evidence-Based Review and Recommendations

Cervical adenocarcinoma in situ is a unique diagnosis whose management needs to be differentiated from the management of the more prevalent squamous cell dysplasia.

This publication represents an extensive literature review with the goal of providing guidelines for the evaluation and management of cervical adenocarcinoma in situ (AIS). The authors drafted the guidelines on behalf of the Society of Gynecologic Oncology, and the guidelines have been reviewed and endorsed by the ASCCP. These guidelines harmonize with the ASCCP Risk-Based Management Consensus Guidelines and provide more specific guidance beyond that provided by the ASCCP guidelines. Examples of updates include recommendations to optimize the diagnostic excisional specimen, AIS management in the setting of positive compared with negative margins on the excisional specimen, surveillance and definitive management after fertility-sparing treatment, and management of AIS in pregnancy. The increasing incidence of AIS, its association with human papillomavirus–18 infection, challenges in diagnosis owing to frequent origin within the endocervical canal, and the possibility of skip lesions all make AIS a unique diagnosis whose management needs to be differentiated from the management of the more prevalent squamous cell dysplasia.

Ovarian metastasis in women with cervical carcinoma in stages IA to IIB: A systematic review and meta-analysis

BACKGROUND

Cervical cancer is one of the common malignancies that afflict women worldwide. In rare cases, cervical cancer leads to ovarian metastasis (OM), resulting in poor outcomes. We conducted a systematic review and meta-analysis to evaluate the incidence and risk factors of OM in patients with adenocarcinoma (ADC) or squamous cell carcinoma (SCC) of the cervix.

METHODS

We searched articles focused on OM in cervical carcinoma in PubMed, Embase, and the Cochrane Central Register of Controlled Trials. A meta-analysis was performed including selected publications. Pooled odds ratio (OR) and 95% confidence interval (95% CI) were calculated using random-effects models. The heterogeneity was evaluated by the I test. I > 50% was considered high heterogeneity.

RESULTS

A total of 12 studies with 18,389 patients with cervical cancer in International Federation of Gynecology and Obstetrics stages IA to IIB were included in the meta-analysis. The overall incidence of OM was 3.61% among patients with ADC and 1.46% among patients with SCC (ADC vs SCC: OR 3.89, 95% CI 2.62-5.78; P < .001). Risk factors for OM were age >40 years (OR 1.79, 95% CI 1.02-3.13), bulky tumor (OR 2.65, 95% CI 1.77-3.95), pelvic lymph node involvement (PLNI; OR 9.33, 95% CI 6.34-13.73), lymphovascular space involvement (LVSI; OR 4.38, 95% CI 1.86-10.31), parametrial invasion (PMI; OR 7.87, 95% CI 5.01-12.36), and corpus uteri invasion (CUI; OR 7.64, 95% CI 2.51-23.24). PLNI, LVSI, and PMI were the leading risk factors, contributing to OM with respective population attributable fractions of 64.8%, 58.8%, and 51.5%.

CONCLUSION

The incidence of OM is relatively low in ADC and SCC patients. Risk factors for OM include PLNI, LVSI, PMI, bulky tumor, CUI, or age over 40 years, with the first 3 contributing more to risk of OM.

[The 2019 FIGO classification for cervical carcinoma-what's new?]

Numerous therapeutic and prognostic studies of cervical carcinoma have necessitated a revision of the FIGO classification.For microinvasive carcinomas, the horizontal dimension is no longer considered and diagnosis and staging will solely be made by the depth of cervical stromal invasion. Lymphovascular invasion beyond the deepest point of stromal infiltration by tumor cells does not alter the stage.There will be a new subclassification of macroinvasive carcinoma confined to the uterine cervix, which will be made by largest tumor extension as follows: FIGO IB1/T1b1 - invasive carcinoma >0.5 cm depth of stromal invasion and ≤2 cm in largest dimension, FIGO IBII/T1b2: - invasive carcinoma >2 cm and ≤4 cm, FIGO IBII/T1b3 - invasive carcinoma >4 cm. Pelvic as well as para-aortic lymph nodes will be defined as regional nodes. Pelvic lymph node metastases only will be categorised as FIGO IIIC1/pN1a and para-aortic lymph node involvement with or without concomitant pelvic involvement will be FIGO IIIC2/pN1b. Uterine corpus as well as adnexal involvement are not relevant for staging purpose.

Oncological Outcomes and Safety of Ovarian Preservation for Early Stage Adenocarcinoma of Cervix: A Systematic Review and Meta-Analysis

Objectives: To evaluate the oncological outcomes and safety of ovarian preservation, and to review the prognostic factors for ovarian metastases in early stage cervical adenocarcinoma.

Methods: PubMed, Embase, and Cochrane databases were searched for publications up to January 2019. Two investigators independently screened the studies for eligibility and extracted specific data. The primary outcomes were overall survival (OS) and progression-free survival (PFS). Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using STATA statistical software version 19.0.

Results: A total of 68 unique manuscripts were identified through the search strategy, and 10 studies were included in the meta-analysis of the safety of ovarian preservation. Fixed-effects model was used because of moderate heterogeneity. Pooled results of the included studies showed that ovarian preservation is not associated with a statistically significant OS (OR 1.00, 95% CI 0.64–1.56, I² = 25.7%) or PFS (OR 0.98, 95% CI 0.57–1.66, I² = 0%) in early stage cervical adenocarcinoma. In addition, 19 studies were included in the review of prognostic factors for cervical adenocarcinoma and risk factors for ovarian metastases. The incidence of ovarian metastases was 0% in stage IA, 2.8% in stage IB, 3.4% in stage IIA, and 11.8% in stage IIB cervical adenocarcinoma. International Federation of Gynecology and Obstetrics (FIGO) stage, tumor size, deep stromal invasion (DSI), lymph node metastasis (LNM), and vaginal invasion were significantly related to poor prognosis. Risk factors associated with ovarian metastases included age, FIGO stage, tumor size, DSI, parametrial invasion, corpus uteri invasion, LNM, vaginal invasion, and blood vessel invasion.

Conclusions: Ovarian preservation in young patients with early stage cervical adenocarcinoma is safe and has no significant effect on OS or PFS. Preserving ovaries in patients with FIGO stage IIB seems not reasonable because of the high rate of ovarian metastasis.
