Factors influencing decisions about surgical treatment of cervical precancerous lesions

HR-HPV viral load quality detection provide more accurate prediction for residual lesions after treatment: a prospective cohort study in patients with high-grade squamous lesions or worse

The relationship between high-risk-human-papillomavirus (HR-HPV) viral loads and residual/recurrence lesion is uncertain. This study aimed to evaluate the clinical value of HR-HPV viral loads to predict the residual/recurrence lesions among women with high-grade squamous lesions or worse (≥ HSIL) after surgery. Finally, 301 women who underwent primary screening of cervical cancer using polymerase-chain-reaction-(PCR)-reverse-dot-blot-(RDB) human papillomavirus (HPV) genotyping and cytology assays were enrolled. They received surgery and took HR-HPV viral loads with a BioPerfectus Multiplex Real-Time PCR assay. Colposcopy biopsies were performed in patients with HPV-16/18(+) and/or TCT ≥ ASCUS with HR-HPV(+). The risk of HR-HPV viral loads and potentials factors for residual/recurrence lesions were analyzed and the optimal cut-off values of HR-HPV viral loads were calculated. The significant differences were found in residual/recurrence lesions among patients with different ages, margin status, cytology and HR-HPV at 6 months (all P < 0.05). Interestingly, HPV viral loads were observed significant differences in the group of residual lesions, not recurrence group. Furthermore, except for HPV-31/33, the viral loads of HP-16/52/58 were significant differences in residual lesions. The cut-off level of HR-HPV viral loads was 5.22 copies/10,000 cells, providing viable triage for the risk of residual lesions. Compared with different follow-up methods, the HR-HPV viral loads ≥ 5.22copies/10,000 cells (HR 3.39, 95% CI 1.57-7.35) had a higher risk for developing residual lesions. HR-HPV viral loads can be a reliable predictor of residual lesions. Furthermore, women with viral loads ≥ 5.22 copies/10,000 cells may have higher risk for residual disease and should be give a more aggressive treatment and follow-up strategy.

Sensitivity of Follow-Up Methods in Patients After Fertility-Sparing Surgery for Cervical Cancers

Objective

The aim of our study was to compare the sensitivity of various methods and their combinations in the follow-up of patients with cervical cancer after fertility-sparing surgery (FSS).

Methods

Included were women with cervical cancer in stages IA2 to IB2 who underwent FSS, which includes pelvic lymphadenectomy, sentinel lymph node biopsy, abdominal radical trachelectomy, vaginal trachelectomy, or needle conization. Follow-up visits were scheduled at 3-month intervals and included symptom-oriented discussion, gynecological and physical examination, colposcopy, Papanicolaou test, human papillomavirus (HPV) DNA test, and ultrasound examination. All cases with a recurrent disease were thoroughly analyzed, and the results of individual examinations were compared.

Results

In total, 43 women (IA2, 8; IB1, 33; IB2, 2) were enrolled. The mean patient age was 31 years; most patients were nulliparous (68.4%, 26/38) with squamous cell cancers (26/38). Abdominal radical trachelectomy was performed in 10 women, simple vaginal trachelectomy was performed in 11 women, and conization was performed in 22 women, according to the tumor characteristics and topography. The median duration of the follow-up reached 37 months. Invasive cancer and high- and low-grade squamous intraepithelial lesions were detected in 8, 1, and 1 patients, respectively. All except 1 event were central, detected within the first year after FSS. Only 2 cases were symptomatic. Colposcopy detected 7 of 10 recurrences; 5 of them were HPV positive, and, in 2 cases, a Papanicolaou test revealed abnormalities. Papanicolaou tests were false positive in 27.7%, especially after trachelectomies.

Conclusions

Most patients in whom cancer recurred after FSS reveal central or pelvic lesions, which can be successfully treated with salvage surgery or radiotherapy. The early detection of recurrence is an essential condition for a favorable oncological outcome. Colposcopy alone and in combination with HPV positivity showed the highest sensitivity for the detection of recurrent diseases, whereas other methods had limited reliability.
