Abdominal Radical Trachelectomy for Early-Stage Cervical Cancer During Pregnancy: A Provocative Surgical Approach. Overview of the Literature and a Single-Institute Experience

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.

A meta-analysis of treatment for early-stage cervical cancer: open versus minimally invasive radical trachelectomy

BACKGROUND

In previous systematic reviews, meta-analysis was lacking, resulting in the statistical difference between the data of different surgeries being impossible to judge. This meta-analysis aims to contrast the fertility results and cancer outcomes between open and minimally invasive surgery.

METHOD

We systematically searched databases including PubMed, Embase, Cochrane, and Scopus to collect studies that included open and minimally invasive radical trachelectomy. A random-effect model calculated the weighted average difference of each primary outcome via Review Manager V.5.4.

RESULT

Eight studies (1369 patients) were incorporated into our study. For fertility results, the Open group excels MIS group in pregnancies-Third trimester delivery [OR = 2.68; 95% CI (1.29, 5.59); P = 0.008]. Nevertheless, there is no statistical difference in clinical pregnancy, miscarriage, and second-trimester rate. Concerning cancer outcomes, no difference was detected in the overall survival [OR = 1.56; 95% CI (0.70, 3.45); P = 0.27] and recurrence [OR = 0.63; 95% CI (0.35, 1.12); P = 0.12]. Concerning surgery-related outcomes, the comprehensive effects revealed that the estimated blood loss of the Open group was higher than that of the MIS group[MD = 139.40; 95% CI (79.05, 199.75); P < 0.0001]. However, there was no difference between the postoperative complication rate in the two groups [OR = 1.52; 95% CI (0.89, 2.60); P = 0.12].

CONCLUSION

This meta-analysis suggested that the fertility result of the Open group may be better than the MIS group, while the MIS group has better surgery-related outcomes. Owing to the poor cases of our study, a more robust conclusion requires more relevant articles in the future.

Does radical trachelectomy (RT) during pregnancy have higher obstetrical and oncological risks than RT before pregnancy?

PURPOSE

Radical trachelectomy (RT) with pelvic lymphadenectomy has become a new treatment option for young patients with uterine cervical cancer stages 1A2-1B1 who desire the preservation of their fertility. However, the application of RT for pregnant patients is still controversial. We comparatively studied both obstetrical and oncological outcomes of pregnant patients who underwent vaginal RT during pregnancy and those who underwent vaginal RT before pregnancy.

METHODS

Both obstetrical and oncological results of eight patients who underwent vaginal RT with pelvic lymphadenectomy during pregnancy in our institute between 2010 and 2020 (Group A), and ten pregnant patients who underwent vaginal RT with pelvic lymphadenectomy before pregnancy during the same period (Group B) were reviewed based on their medical charts.

RESULTS

There were neither significant differences in blood loss, surgical time, or surgical completeness between Group A and Group B, nor were there significant differences in obstetrical outcomes between the two groups. However, two of the eight patients in Group A had recurrence of the cancer. None of the patients in Group B has shown any signs of recurrence thus far.

CONCLUSION

Vaginal RT during pregnancy does not affect the obstetrical prognoses of patients with early invasive uterine cervical cancer, and it might be a tolerable treatment modality for them. However, oncologically, it should be performed carefully as there is a risk of recurrence.

The Double Life-Saving Approach of Abdominal Radical Trachelectomy during Pregnancy for Early-Stage Cervical Cancer-An Overview of the Literature and Our Institutional Experience

(1) Background: Cervical cancer is the most common type of cancer encountered during pregnancy, with a frequency of 0.8–1.5 cases per 10,000 births. It is a dire condition endangering patients’ lives and pregnancy outcomes, and jeopardizing their fertility. However, there is a lack of current evidence and consensus regarding a standard surgical technique for pregnant patients who suffer from this condition during pregnancy. The study aims to comprehensively update all published data, evaluating the obstetrical and oncological results of pregnant patients who underwent abdominal radical trachelectomy during early stages of cervical cancer. (2) Methods: A literature search on the Medline, PubMed, and Google Scholar databases was performed, including all articles in question up to July 2020. This study presents an overview of the literature and our institutional experience. (3) Results: A total of 25 cases of abdominal radical trachelectomy were performed during pregnancy for early cervical cancer, including the five cases managed by the authors. Of these, 81% (19 patients) gave birth to live newborns through elective C-section, and 19% (6 patients) experienced miscarriage shortly after the procedure. None of the 25 patients (100%) reported disease recurrence. (4) Conclusions: The results of the current study were satisfactory. However, abdominal radical trachelectomy does not represent the current standard of care for cervical cancer during pregnancy, but it could play an important role if more evidence on its effectiveness will be provided.
