Fertility-sparing surgery after neo-adjuvant chemotherapy in women with cervical cancer larger than 4 cm: a systematic review

T1 mapping and multimodel diffusion-weighted imaging in the assessment of cervical cancer: a preliminary study

OBJECTIVE

To evaluate the clinical feasibility of T1 mapping and multimodel diffusion-weighted imaging (DWI) for assessing the histological type, grade, and lymphovascular space invasion (LVSI) of cervical cancer.

METHODS

Eighty patients with cervical cancer and 43 patients with a normal cervix underwent T1 mapping and DWI with 11 b-values (0-2000 s/mm2). Monoexponential, biexponential, and kurtosis models were fitted to calculate the apparent diffusion coefficient (ADC), pure molecular diffusion (D), pseudo-diffusion (D*), perfusion fraction (f), mean diffusivity (MD), and mean kurtosis (MK). Native T1 and DWI-derived parameters (ADCmean, ADCmin, Dmean, Dmin, D*, f, MDmean, MDmin, MKmean, and MKmax) were compared based on histological type, grade, and LVSI status.

RESULTS

Native T1 and DWI-derived parameters differed significantly between cervical cancer and normal cervix (all p < 0.05), except D* (p = 0.637). Native T1 and MKmean varied significantly between squamous cell carcinoma (SCC) and adenocarcinoma (both p < 0.05). ADCmin, Dmin, and MDmin were significantly lower while MKmax was significantly higher in the high-grade SCC group than in the low-grade SCC group (all p < 0.05). LVSI-positive SCC had a significantly higher MKmean than LVSI-negative SCC (p < 0.05).

CONCLUSION

Both T1 mapping and multimodel DWI can effectively differentiate cervical cancer from a normal cervix and cervical adenocarcinoma from SCC. Furthermore, multimodel DWI may provide quantitative metrics for non-invasively predicting histological grade and LVSI status in SCC patients.

ADVANCES IN KNOWLEDGE

Combined use of T1 mapping and multimodel DWI may provide more comprehensive information for non-invasive pre-operative evaluation of cervical cancer.

Laparoscopic Radical Trachelectomy after Neoadjuvant Chemotherapy for Fertility Preservation in Early-Stage Bulky Cervical Cancer: A Case Report and Literature Review

Management of early-stage cervical cancer (CC) in young women often faces challenges to preserve fertility, as well as to achieve an adequate oncological outcome. Although existing evidence supports a fertility-sparing treatment in the case of tumors <2 cm in diameter, the approach is less clear in bulky early-stage CC. In addition, the outcomes of radical trachelectomy performed by minimally invasive techniques are also highly debatable. Highlighting the high incidences of young women with early-stage CC, the lack of sufficient data raises considerable hindrances towards the proper counseling of this vulnerable patient group. In this report, a case of a young woman with bulky early-stage CC with a strong desire to preserve fertility is presented. A satisfactory oncological outcome was achieved after neoadjuvant chemotherapy followed by laparoscopic radical trachelectomy. Ongoing prospective trials are expected to provide stronger evidence on this topic.

Fertility-sparing surgery in early-stage cervical cancer: laparoscopic versus abdominal radical trachelectomy

Background

Radical trachelectomy is an acceptable alternative to radical hysterectomy for patients with early-stage cervical cancer who wish to preserve reproductive function. This study is designed to compare the laparoscopic versus abdominal radical trachelectomy and provide oncological and obstetric outcome data on patients who have undergone fertility-sparing surgery.

Methods

We retrospectively analyzed all early-stage cervical cancer patients who underwent abdominal radical trachelectomy (ART) or laparoscopic radical trachelectomy (LRT) between January 2005 and June 2017 in West China Second University Hospital, Sichuan University. Patients' clinical details and follow-up were obtained from hospital records.

Results

A total of 33 patients (5 with IA1, 2 with IA2, and 26 with 1B1) were included, including 18 patients treated with ART and 15 patients treated with LRT. The median age at initial diagnosis was 30.00 ± 4.30 years (range 22–39). The mean follow-up time was 74.67 months. Among the 33 patients, 2 patients (6.06%, 1 abdominal/1 laparoscopic) developed recurrence, and there are no evidence of disease for the remaining 31 patients till now. The overall survival rate 96.99% (32/33). The LRT group had a shorter hospital stay (P = 0.01) and less blood loss (P < 0.01) than the ART group. There is no significant difference in the length of operative time (P = 0.48) between the two surgical routes. Overall, 15/33 patients (45.45%) have tried to conceive. 6 (40.00%) patients were pregnant and 6 (40.00%) patients were infertility. The ART group had a higher clinical pregnancy rate (P = 0.03) than the LRT group.

Conclusions

There is no statistically significant difference in oncological outcome between the two surgical approaches. The clinical pregnancy rate in the ART group was significant higher than that in the LRT group. However, LRT resulted in less blood loss and decreased length of hospital stay.
