Conservative management for villoglandular papillary adenocarcinoma of the cervix diagnosed during pregnancy followed by a successful term delivery: a case report and a review of the literature

Cervical Cancer Associated with Pregnancy: Current Challenges and Future Strategies

Cancer during pregnancy is defined as a tumor diagnosed in a pregnant woman or up to 1-year post-partum. While being a rare disease, cervical cancer is probably one of the most challenging medical conditions, with the dual stake of treating the cancer without compromising its chances for cure, while preserving the pregnancy and the health of the fetus and child. To date, guidelines for gynecological cancers are provided through international consensus meetings with expert panels, giving insights on both diagnosis, treatment, and obstetrical care. However, these expert guidelines do not discuss the various approaches than can be found within the literature, such as alternative staging modalities or innovative surgical approaches. Also, the obstetrical care of women diagnosed with cervical cancer during pregnancy requires specific considerations that are not provided within our current standard of care. This systematic review aims to fill the gap on current issues with regards to the management of cervical cancer during pregnancy and provide future directions within this evolving landscape.

Estrogen receptor-positive adenocarcinoma of the cervix presenting during pregnancy: Two case reports and review of the literature

•

Estrogen receptor or progesterone receptor positivity are unusual in cervical adenocarcinomas.

•

Estrogen receptor positivity in pregnancy could be associated with a faster growth rate.

•

Both patients presented remain free of recurrence after definitive treatment.

The incidence of adenocarcinoma of the cervix in pregnancy is exceptionally rare, and thus there is no consensus on its management. Here, we report two cases of adenocarcinoma of the cervix diagnosed in the context of pregnancy. In our first case, a patient referred to colposcopy for atypical glandular cells of undetermined significance was subsequently diagnosed with well differentiated endocervical adenocarcinoma on cone biopsy. Just prior to the cone biopsy, she was incidentally found to have a first trimester pregnancy loss. The patient subsequently underwent a radical hysterectomy and bilateral sentinel lymph node dissection. Final pathology revealed a stage 1B1 (FIGO 2009) well differentiated adenocarcinoma of the cervix. Interestingly, the tumour was positive for estrogen receptor, which is unusual for cervical adenocarcinoma.

In our second case, a patient presented with a pedunculated, exophytic cervical neoplasm at 31 weeks GA with self-limiting antepartum hemorrhage. The primary lesion measured 52 mm in diameter on MRI and was amputated at the base during the patient’s elective repeat cesarean section. Final pathology revealed a stage IB2 (FIGO 2009) mucinous adenocarcinoma of the cervix. The patient subsequently underwent a radical hysterectomy and bilateral pelvic lymph node dissection 17 weeks after initial presentation. The depth of invasion was 2.2 mm, restricted to the inner third of the cervical wall, and there was no lymphovascular space invasion in the surgical specimen. Surgical margins, parametria, and lymph nodes were all negative for adenocarcinoma. This tumour was also found to be estrogen receptor/progesterone receptor (ER/PR) positive, again unusual for cervical adenocarcinoma. P16 was strongly positive and HPV DNA studies were also positive for human papilloma virus 18. The patient received adjuvant external beam radiotherapy to the pelvis and currently remains in remission.

Villoglandular adenocarcinoma of the uterine cervix: a systematic review and meta-analysis

Purpose

Villoglandular adenocarcinoma (VGA) of the uterine cervix has been classified as a rare subtype of cervical adenocarcinoma with good prognosis. A conservative surgical approach is considered feasible. The main risk factor is the presence of other histologic types of cancer.

In this largest systematic review to date, we assess oncological outcomes associated with conservative therapy compared to those associated with invasive management in the treatment of stage Ia and Ib₁ VGA.

Methods

Case series and case reports identified by searching the PubMed database were eligible for inclusion in this review (stage Ia–Ib₁).

Results

A total of 271 patients were included in our literature review. 54 (20%) patients were treated by “conservative management” (conization, simple hysterectomy, and trachelectomy) and 217 (80%) by “invasive management” (radical hysterectomy ± radiation, hysterectomy, and radiation). Recurrences of disease (RODs) were found in the conservative group in two (4%) cases and in the invasive group in nine (4%) cases. There was no significant difference in disease-free survival (DFS) according to conservative or invasive treatment (p = 0.75). The histology of VGA may be complex with underlying usual adenocarcinoma (UAC) combined with VGA.

Conclusion

The excellent prognosis of pure VGA and the young age of the patients may justify the management of this tumor using a less radical procedure. The histological diagnosis of VGA is a challenge, and pretreatment should not be based solely on a simple punch biopsy but rather a conization with wide tumor-free margins.

A retrospective review of 11 cases of villoglandular papillary adenocarcinoma of the uterine cervix and a review of the literature

Villoglandular papillary adenocarcinoma (VGPA) of the uterine cervix is a rare subtype of cervical adenocarcinoma (AC) that accounts for 3.7-4.8% of cervical AC. Compared with ordinary adenocarcinoma, VGPA is associated with a lower incidence, younger age and better prognosis. Treatment with fertility-preserving surgery is also possible. The present study analyzed cases treated in The Second Hospital of Jilin University (Changchun, Jilin, China) between January 2010 and December 2014. A total of 11 cases were selected; of these, 7 cases were pathologically confirmed. The remaining 4 cases were diagnosed as VGPA upon the pathological examination of the biopsy, but confirmed as another type of adenocarcinoma upon analysis of the surgical pathology. The median age of the patients whose pathology was confirmed post-operatively was 36 years, and all cases were positive for human papillomavirus (HPV). As all 7 patients had no requirement for further fertility, a radical hysterectomy was performed, with or without adjuvant therapy. The follow-up time ranged from 7-57 months, with a mean time of 29 months. There was no evidence of recurrence in any of the patients. All the patients remain alive to date. The results of the present study indicated that HPV infection is likely to be the cause of VGPA, and the prognosis of VGPA tends to be better compared with other types of adenocarcinoma. However, the number of studies that have reported cases of VGPA remains small, and all are retrospective analyses with short follow-up times. Therefore, physicians selecting treatment options for patients with VGPA should exercise caution.

A Case of Villoglandular Papillary Adenocarcinoma of the Uterine Cervix Diagnosed during Early Pregnancy Followed by Successful Term Delivery

Villoglandular papillary adenocarcinoma (VPA) is a very rare subtype of adenocarcinoma of the uterine cervix, but a well-recognized variant of cervical adenocarcinoma with a favorable prognosis and generally occurring in women of child-bearing age. Only five cases of VPA and pregnancy have been reported. Herein, we report a case of VPA diagnosed during early pregnancy and managed successfully with conservative measures; our patient delivered a healthy baby in full term. A successful pregnancy can be completed in patients with VPA without lymph-vascular invasion, when treated conservatively. This management is particularly desirable in young women to preserve reproductive capability.
