Vaginosonography versus MRI in Pre-Treatment Evaluation of Early-Stage Cervical Cancer: An Old Tool for a New Precision Approach?

This study aims to analyze the sensitivity of vaginosonography (VGS) and magnetic resonance imaging (MRI) in the preoperative local evaluation of early-stage cervical cancers and to assess their accuracy in the detection of tumors, size of the lesions and stromal invasion by comparing them with the final histopathology report. This single-center study included 56 consecutive patients with cervical cancer who underwent VGS and MRI from November 2012 to January 2021. VGS significantly overestimated the lesion size by 2.7 mm (p = 0.002), and MRI underestimated it by 1.9 mm (p = 0.11). Both MRI and VGS had a good concordance with the pathology report (Cohen's kappa of 0.73 and 0.81, respectively). However, MRI had a false-negative rate (38.1%) that was greater than VGS (0%) in cases of cervical tumor size <2 cm. We found a good concordance between histology and VGS in the stromal infiltration assessment, with 89% sensitivity (95% CI 0.44−0.83) and 89% specificity (95% CI 0.52−0.86). VGS is a simple, inexpensive, widely available, and fast execution method that can complement ultrasound in particular cases and show a good correlation with MRI in the assessment of tumor dimensions, with a better performance in detecting small tumors (<2 cm).

The Potential Impact of High-Risk Human Papillomavirus-Negative Cervical Intraepithelial Neoplasia 2+ on Primary Human Papillomavirus Screening.

OBJECTIVES: To investigate the prevalence of high-risk human papillomavirus (HPV)-negative cervical intraepithelial neoplasia (CIN) and invasive cervical carcinoma (ICC) and to analyze the distribution of other genotypes in this subset. METHODS: In total, 431 women who underwent excisional surgical treatment for CIN or ICC at the European Institute of Oncology, Milan, Italy, from January 2016 to December 2017 were retrospectively analyzed. The Linear Array HPV genotyping test (Roche Diagnostics) was performed on a postaliquot from high-risk-HPV-negative liquid-based cervical specimens, when available. Patient characteristics and the prevalence of high-risk-HPV-negative CIN grade 2 or worse (CIN2+) were tabulated. We used t tests to compare age between high-risk-HPV-positive and high-risk-HPV-negative patients. RESULTS: Overall, 8.9% of CIN2+ and 7.5% of ICC cases were high-risk HPV negative. There was no age difference between high-risk-HPV-negative CIN2+ women (mean [SD], 41.3 [8.7] years) and high-risk-HPV-positive women (mean [SD], 39.5 [9.0] years) (P = .28). The Linear Array result was available in 22 cases. Most high-risk-HPV-negative patients were positive for a single other genotype infection (32.6%). HPV 73 was the most prevalent genotype, followed by HPV 53 and HPV 84. HPV 26 was detected in 1 case of ICC. CONCLUSIONS: Our results showed a not-negligible proportion of high-risk-HPV-negative CIN2+, suggesting that cotesting would not miss these cases.

Borderline ovarian tumor in pregnancy: can surgery wait? A case series.

PURPOSE: To study the characteristics of borderline tumors (BOT) diagnosed during pregnancy, as either first diagnosis or relapse, to evaluate safety of expectant management. METHODS: 15 women affected by BOT during pregnancy were included, to evaluate clinical and histo-pathological characteristics. Age of patient, parity, gestational age, follow-up time, size of tumor, surgical approach, type and timing of surgery, FIGO stage, and histologic type were obtained through retrospective review. RESULTS: All patients except one were diagnosed with serous BOT (BOTs). Median follow-up time was 147 ± 57 months. Eight women received first diagnosis of BOT and seven had diagnosis of BOT recurrence during pregnancy, including three with a second relapse and four with a third relapse. BOT were diagnosed at FIGO stage I in most patients (75%) of the first group and in 14.3% of the second group, respectively. Micropapillary pattern was present in 71.4% of patients with first diagnosis of BOT, but only in 14.2% in case of relapse. All relapses were BOTs. No patient with BOT and concomitant pregnancy developed an invasive recurrence later. Overall, 24 relapses occurred in 10 patients (66.7%). Altogether 24 pregnancies occurred during follow-up, with a high livebirth rate (91.6%) and only 2 spontaneous miscarriages. CONCLUSION: According to our experience, an "expectation management" could be a safe option in case of both relapse of BOTs during pregnancy and first suspicion of BOT in pregnant women at advanced gestational age.

Definitive Radiotherapy for Primary Squamous Cell Carcinoma of the Vagina: Are High-Dose External Beam Radiotherapy and High-Dose-Rate Brachytherapy Boost the Best Treatment? Experience of Two Italian Institutes.

INTRODUCTION: We assessed the clinical outcome and survival of 70 patients with primary vaginal squamous cell carcinoma undergoing radiotherapy (RT) at the Divisions of Radiotherapy, University of Pisa and ASST Cremona between January 1995 and June 2016. METHODS: 58 patients received external beam RT (EBRT) to the entire vagina, para-vaginal area and pelvic nodes (total dose: 45-50.4 Gy). 29 patients (41.4%) received concomitant weekly cisplatin 40 mg/m2. 35 patients received an additional (15-36 Gy) high-dose-rate (HDR) brachytherapy (BT) boost and 13 received an additional (9-25 Gy) EBRT boost to the primary tumor site. 12 women exclusively received HDR-BT up to a total dose of (30-58 Gy). RESULTS: Median overall survival (OS) was 85 months. A total RT dose of > 60 Gy was significantly associated with a better OS (p = 0.015). There was a trend for a better OS for patients aged < 70 years and for those undergoing EBRT to the entire vagina and pelvis plus BT boost. The most common grade 1-2 acute toxicities were diarrhea (24.1%) and cystitis (20.7%); grade 3 cystitis only occurred in 2 patients (3.4%). CONCLUSIONS: EBRT followed by BT boost seems to be the best treatment for vaginal carcinoma. The total dose of RT should be > 60 Gy.
