Early Stage Cervical Cancer

Despite the recent advances in the management of cervical cancer using cisplatin-based concurrent chemoradiotherapy, substantial treatment failure still occurs, especially in advanced-stage patients and early-stage cervical cancer patients with high-risk prognostic factors. Therefore, efforts to further improve the survival and quality of life of these patients are necessary. Nedaplatin (cis-diammine-glycoplatinum), a derivative of cisplatin, was developed with the aim of producing a treatment with a similar effectiveness to cisplatin but decreased renal and gastrointestinal toxicities. Based on the promising results of preclinical studies, the clinical efficacy of nedaplatin as a radiosensitizing agent was evaluated in patients with cervical cancer. Retrospective analysis of nedaplatin-based concurrent chemoradiotherapy (CCRT) against cervical cancer suggested that nedaplatin-based CCRT can be considered as an alternative to cisplatin-based CCRT in both early-stage and advanced-stage cervical cancer patients. However, due to the lack of a randomized controlled study, nedaplatin-based CCRT has not been convincingly proven to be clinically effective in patients with cervical cancer. Further investigations in randomized controlled trials are therefore needed.

ObjectivesThis multicentric retrospective study investigates the early and long-term self-reported urinary, bowel, and sexual dysfunctions in early-stage cervical cancer patients who submitted to laparoscopic total mesometrial resection (L-TMMR), total laparoscopic radical hysterectomy, vaginal-assisted laparoscopic radical hysterectomy, and laparoscopic-assisted radical vaginal hysterectomy.MethodsCervical cancer patients, FIGO (International Federation of Gynecology and Obstetrics) stage IA2–IB1/IIA1 who submitted to nerve-sparing radical hysterectomy were recruited. Pelvic functions were assessed within 30 days (early outcome) and 12 months after surgery (long-term outcome).ResultsTwo hundred thirteen subjects receiving nerve-sparing radical hysterectomy were enrolled. Laparoscopic total mesometrial resection was performed in 46 patients (21.6%), total laparoscopic radical hysterectomy in 65 patients (30.5%), vaginal-assisted laparoscopic radical hysterectomy in 54 patients (25.4%), and laparoscopic-assisted radical vaginal hysterectomy in 48 women (22.5%). Operative time was significantly lower in the L-TMMR group (240 minutes; range, 120–670 minutes; P = 0.001). The overall perioperative complication rate was 11.3%, with no statistically significant differences among the 4 groups. Stress incontinence and sensation of bladder incomplete emptying were detected, respectively, in 54 patients (25.6%) and 65 patients (30.7%) with a significantly lower prevalence among those in the L-TMMR group, which resulted, respectively, in 11.1% (P = 0.022) and 13.3% (P = 0.036). The prevalence rates of constipation, sensation of incomplete bowel emptying, and effort during evacuation were significantly higher among those in the L-TMMR group, resulting in, respectively, 37% (P = 0.001), 42.3% (P = 0.012), and 50% (P = 0.039). One hundred forty-nine patients (70%) were sexually active. Fifty-eight women (38.9%) reported low enjoyment, 83 women (55.7%) medium enjoyment, and 8 women (5.4%) reported high enjoyment, without statistically significant differences among the 4 groups.ConclusionsLaparoscopic total mesometrial resection is associated with improved long-term urinary autonomic functions and worse gastrointestinal autonomic outcome. Further larger prospective trials are needed to evaluate both the oncological and functional outcomes in order to establish the most appropriate surgical approach for early-stage cervical cancer patients.

Radiomics Signature

Objectives: To investigate the prognostic role of Magnetic Resonance Imaging (MRI) based radiomics signature and clinical characteristics for overall survival (OS) and disease-free survival (DFS) in the early-stage cervical cancer. Methods: A total of 207 cervical cancer patients (training cohort: n = 144; validation cohort: n = 63) were enrolled. 792 radiomics features were extracted from T2-weighted (T2W) and diffusion weighted imaging (DWI). 19 clinicopathological parameters were collected from the electronic medical record system. Least absolute shrinkage and selection operator (LASSO) regression analysis was used to select significant features to construct prognostic model for OS and DFS. Kaplan-Meier (KM) analysis and log-rank test were applied to identify the association between the radiomics score (Rad-score) and survival time. Nomogram discrimination and calibration were evaluated as well. Associations between radiomics features and clinical parameters were investigated by heatmaps. Results: A radiomics signature derived from joint T2W and DWI images showed better prognostic performance than that from either T2W or DWI image alone. Higher Rad-score was associated with worse OS (p < 0.05) and DFS (p < 0.05) in the training and validation set. The joint models outperformed both radiomics model and clinicopathological model alone for 3 year OS and DFS estimation. The calibration curves reached an agreement. Heatmap analysis demonstrated significant associations between radiomics features and clinical characteristics. Conclusions: The MRI-based radiomics nomogram showed a good performance on survival prediction for the OS and DFS in the early-stage cervical cancer. The prediction of the prognostic models could be improved by combining with clinical characteristics, suggesting its potential for clinical application. Advances in knowledge: This is the first study to build the radiomics-derived models based on T2W and DWI images for the prediction of survival outcomes on the early stage cervical cancer patients, and further construct a combined risk scoring system incorporating the clinical features.

Early Stage Cervical Cancer

ObjectiveConventional radical hysterectomy with pelvic lymphadenectomy (RHL) for early-stage cervical cancer is associated with significant bladder, anorectal, and sexual dysfunction. Nerve-sparing modification of RHL (NS-RHL) has been developed with the aim to reduce surgical treatment-related morbidity. Postoperative radiation therapy (RT) is offered to patients with unfavorable prognostic features to improve local control. The aim of the study was to assess self-reported morbidity of various types of treatment in cervical cancer patients.MethodsSelf-reported symptoms were prospectively assessed before and 1 and 2 years after treatment by the Dutch Gynaecologic Leiden Questionnaire.ResultsIncluded were 229 women (123 NS-RHL and 106 conventional RHL). Ninety-four (41%) received RT. Up to 2 years (response rate, 81%), women reported significantly more bowel, bladder, and sexual symptoms compared with the pretreatment situation. No significant difference was found between the conventional RHL and NS-RHL with the exception of the unexpected finding that a smaller percentage in the NS-RHL group (34% vs 68%) complained about numbness of the labia and/ or thigh. Radiation therapy had a negative impact on diarrhea, urine incontinence, lymphedema, and sexual symptoms (especially a narrow/short vagina).ConclusionsIn the current longitudinal cohort study, treatment for early-stage cervical cancer was associated with worse subjective bladder, anorectal, and sexual functioning, irrespective of the surgical procedure used. Postoperative RT resulted in a significant deterioration of these functions. The results have to be interpreted with caution in view of the study design and method used.
