A Controlled Study on Vaginal Blood Flow During Sexual Arousal Among Early-Stage Cervical Cancer Survivors Treated With Conventional Radical or Nerve-Sparing Surgery With or Without Radiotherapy

Sexual Health and Quality of Life in Patients With Low-Risk Early-Stage Cervical Cancer: Results From GCIG/CCTG CX.5/SHAPE Trial Comparing Simple Versus Radical Hysterectomy

PURPOSE

Simple hysterectomy and pelvic node assessment (SHAPE) is a phase III randomized trial (ClinicalTrials.gov identifier: NCT01658930) reporting noninferiority of simple compared with radical hysterectomy for oncologic outcomes in low-risk cervical cancer. This study presents secondary outcomes of sexual health and quality of life (QOL) of the SHAPE trial.

METHODS

Participants were randomly assigned to receive either radical or simple hysterectomy. Sexual health was assessed up to 36 months postoperatively using the Female Sexual Function Index (FSFI) and Female Sexual Distress Scale-Revised and QOL using European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 and Cervical Cancer-Specific Module (QLQ-CX24) questionnaires.

RESULTS

Among participants with at least one QOL measure, clinical and pathologic characteristics were balanced and with no differences in preoperative baseline scores for sexual health or QOL between groups. FSFI total score met the cutoff for dysfunction up to 6 months (P = .02) in the radical hysterectomy group. Group differences favored simple hysterectomy for FSFI subscales: desire and arousal at 3 months (P ≤ .001) and pain and lubrication up to 12 months (P ≤ .018). Both groups met the cutoff for sexual distress but was higher in radical hysterectomy at 3 months (P = .018). For QLQ-CX24, symptom experience was significantly better up to 24 months (P = .031) and body image better at 3, 24, and 36 months (P ≤ .01) for simple hysterectomy. Sexual-vaginal functioning was significantly better up to 24 months (P ≤ .022) and more sexual activity up to 36 months (P = .024) in the simple hysterectomy arm. Global health status was significantly higher at 36 months for simple hysterectomy (P = .025).

CONCLUSION

Simple hysterectomy was associated with lower rates of sexual dysfunction than radical hysterectomy, with a lower proportion of women having sustained sexual-vaginal dysfunction. These results further support the benefit of surgical de-escalation for low-risk cervical cancer.

Tailoring parametrectomy for early cervical cancer (Stage IA-IIA FIGO): a review on surgical, oncologic outcome and sexual function

INTRODUCTION

Cervical cancer is currently one of the most common cancers afflicting the female population worldwide and in industrialized countries the presence of screening and a specific diagnostic and therapeutic process has favored early diagnosis of cervical cancer. In literature have found that reducing the radicality on the parametria in early cervical cancer (ECC), reduces complications without impacting oncological outcomes, but the data in the literature are not yet clear.

EVIDENCE ACQUISITION

Searching on PubMed, we included 1473 articles from January 1974 to 2020. We identified all the studies that compared different type of radical hysterectomy in the primary surgical treatment of ECC. 16 articles were elected for the review.

EVIDENCE SYNTHESIS

Modified radical hysterectomy (Piver II/Querleu-Morrow Type B) in ECC, if compared to CRH (Piver III/Querleu-Morrow Type C2), is not associated with worse cancer outcome and patient survival, but it is associated with a minor operating time, lower blood loss and minor bladder dysfunction. Nerve sparing radical hysterectomy approach (NSRH/Querleu-Morrow Type C1) compared to CRH (Piver III/Type C2) in the ECC, with our data we can confirm a non-inferiority regarding the oncological outcome.

CONCLUSIONS

Reduced radicality on the parametrium offers positive effects on the quality of life (sexual life and bladder function) of patients without impacting on survival, oncological outcome.

Nerve-Sparing Systematic Lymph Node Dissection in Gynaecological Oncology: An Innovative Neuro-Anatomical and Surgical Protocol for Enhanced Functional Outcomes

Whilst systematic lymph node dissection has been less prevalent in gynaecological cancer cases in the last few years, there is still a good number of cases that mandate a systematic lymph node dissection for diagnostic and therapeutic purposes. In all of these cases, it is crucial to perform the procedure as a nerve-sparing technique with utmost exactitude, which can be achieved optimally only by isolating and sparing all components of the aortic plexus and superior hypogastric plexus. To meet this purpose, it is essential to provide a comprehensive characterization of the specific anatomy of the human female aortic plexus and its variations. The anatomic dissections of two fresh and 17 formalin-fixed female cadavers were utilized to study, understand, and decipher the hitherto ambiguously annotated anatomy of the autonomic nervous system in the retroperitoneal para-aortic region. This study describes the precise anatomy of aortic and superior hypogastric plexus and provides the surgical maneuvers to dissect, highlight, and spare them during systematic lymph node dissection for gynaecological malignancies. The study also confirms the utility and feasibility of this surgery in gynaecological oncology.

Optimizing Women's Sexual Function and Sexual Experience After Radical Cystectomy

Survivorship in bladder cancer has improved in terms of lower morbidity, mortality, and improved oncological outcomes. However, there is a dearth of research on women's quality of life, specifically, on the effect of radical cystectomy on women's sexual function and sexual experience. This narrative literature review focuses on the current state of knowledge about women's sexual function after cystectomy, identifies patient and provider-related factors that have contributed to the lack of research and sexual health support in clinical practice, and proposes a model for sexual rehabilitation as well as future areas for research.

Dosimetric comparison of library of plans and online MRI-guided radiotherapy of cervical cancer in the presence of intrafraction anatomical changes

Background

Online magnetic resonance imaging (MRI)-guided radiotherapy of cervical cancer has the potential to further reduce dose to organs at risk (OAR) as compared to a library of plans (LOP) approach. This study presents a dosimetric comparison of an MRI-guided strategy with a LOP strategy taking intrafraction anatomical changes into account.

Methods

The 14 patients included in this study were treated with chemo radiation at our institute and received weekly MRIs after informed consent. The MRI-guided strategy consisted of treatment plans created on the weekly sagittal MRI with 3 mm and 5 mm planning target volume (PTV) margin for clinical target volume (CTV) cervix-uterus (MRI_3mm and MRI_5mm). The plans for the LOP strategy were based on interpolations of CTV cervix-uterus on pretreatment full and empty bladder scans. Dose volume histogram (DVH) parameters were compared for targets and OARs as delineated on the weekly transversal MRI, which was acquired on average 10 min after the sagittal MRI.

Results

For the MRI_5mm strategy D_98% of the high-risk CTV was at least 95% for all weekly MRIs of all patients, while for the LOP and MRI_3mm strategy this requirement was not satisfied for at least one weekly MRI for 1 and 3 patients, respectively. The average reduction of the volume of the reference dose (95% of the prescribed dose) as compared to the LOP strategy was 464 cm³ for the MRI_3mm strategy, and 422 cm³ for the MRI_5mm strategy. The bowel bag constraint V_40Gy < 350 cm³ was violated for 13 patients for the LOP strategy and for 5 patients for both MRI_3mm and MRI_5mm strategy.

Conclusions

With online MRI-guided radiotherapy of cervical cancer considerable sparing of OARs can be achieved. If a new treatment plan can be generated and delivered within 10 min, an online MRI-guided strategy with a 5 mm PTV margin for CTV cervix-uterus is sufficient to account for intrafraction anatomical changes.
