Comparing the effects of alcohol sclerotherapy with those of surgery on anti-Müllerian hormone and ovarian reserve after endometrioma treatment. A prospective multicenter pilot cohort study.

STUDY OBJECTIVE: To compare the effects of ultrasound-guided aspiration and ethanol sclerotherapy with those of laparoscopic surgery on anti-Müllerian hormone (AMH) levels and ovarian reserve in benign-appearing ovarian endometrioma. DESIGN: A prospective, cohort pilot study. SETTING: Multiple centers, Spain. PATIENTS: Forty patients with a suspected ovarian endometrioma with a maximum diameter of 35-100 mm. Serum hormonal concentrations were analyzed in 26 of these women. INTERVENTIONS: Two groups: one that received US-guided aspiration plus alcohol sclerotherapy (n = 16) and the other that underwent laparoscopic cystectomy (n = 10). MEASUREMENTS AND MAIN RESULTS: We studied serum hormonal concentrations (AMH, FSH and 17-ß-estradiol) and antral follicle counts (AFC) in each patient at baseline, and after the procedures and pregnancies. No differences were found when comparing AMH and FSH concentrations before and after each procedure. 17-ß-estradiol concentrations were significantly increased after alcohol sclerotherapy (p < 0.001). AFC recovery after 6 months seemed to be higher after sclerotherapy than after surgery. Three patients became pregnant in the sclerotherapy group. CONCLUSION: This pilot study indicated that alcohol sclerotherapy preserves fertility in patients with endometriomas better than surgery, with significant increases in serum estradiol concentrations, possible AFC recovery and spontaneous pregnancies observed in the patients after sclerotherapy.

Can we avoid axillary lymph node dissection in N2 breast cancer patients with chemo-sensitive tumours such as HER2 and TNBC?

PURPOSE: To find a group of cN2 patients or patients with high axillary burden who become ypN0 after neoadjuvant chemotherapy (NACT) and who may benefit from avoiding a lymphadenectomy. METHODS: A retrospective observational cohort study was conducted with 221 clinically staged N2 patients or patients with at least 3 suspicious lymph nodes found by ultrasound at diagnosis. The predictive factors for ypN0 analysed were age, MRI-determined tumour size, histological subtype, the Nottingham histologic grade, surrogate molecular subtype, ki-67 and vascular invasion when present. Clinical and radiological responses after NACT were also evaluated. Univariate and multivariate analyses by logistic regression were performed. Distant disease-free survival (DDFS) was calculated in relation to the status of the axillary lymph nodes after NACT. RESULTS: After NACT, 89 patients (40.3%) had axillary pathologic complete response (pCR) (ypN0) and 132 (59.7%) had residual axillary disease (ypN+). Molecular surrogate subtype, Ki-67 expression, and the clinical and radiological responses to NACT were the only independent factors associated with ypN0. Axillary pCR was observed more often in HER2-positive and triple-negative tumours than in luminal ones (OR 7.5 and 3.6, respectively). DDFS was 88.7% (95% CI 80.7-96.7%) for ypN0 and 56.2% (95% CI 32.1-80.3%) for ypN+ (p = 0.09). CONCLUSIONS: In HER2-positive and triple-negative breast cancer patients staged as cN2 or with high axillary burden before NACT, a sentinel lymph node biopsy after NACT could be recommended if there is a clinical and radiological response.

Ethanol Sclerotherapy versus Laparoscopic Surgery for Endometrioma Treatment: A Prospective, Multicenter, Cohort Pilot Study.

STUDY OBJECTIVE: To compare the cost-effectiveness of ultrasound (US)-guided aspiration and ethanol sclerotherapy versus laparoscopic surgery for benign-appearing ovarian endometrioma. DESIGN: Prospective, cohort pilot study. SETTING: Multiple centers, Spain. PATIENTS: Forty patients with suspected ovarian endometrioma identified by US, with a maximum diameter of 35 to 100 mm, of whom 33 met inclusion criteria. INTERVENTIONS: The study group (n = 17) underwent US-guided aspiration plus sclerotherapy with ethanol, and the control group (n = 14) underwent laparoscopic cystectomy. MEASUREMENTS AND MAIN RESULTS: Recurrence, complications, and direct costs were compared. One of 17 sclerotherapy patients recurred (5.9%) compared with 4 of 14 laparoscopic surgery patients (28.6%) (odds ratio 0.18, 0.01-1.53). No serious adverse effects (Clavien-Dindo ≥ III) were observed in the sclerotherapy group; 1 patient in the surgery group had a Clavien-Dindo IIIb complication. Median hospital direct costs were significantly lower in the sclerotherapy group than those in the surgery group-266 euros versus 2189 euros. CONCLUSION: Ethanol sclerotherapy seems to be cost-effective for endometrioma and also appears to reduce complications. In this pilot study, recurrence was not higher than with conventional surgery.

Radiofrequency Ablation Followed by Surgical Excision versus Lumpectomy for Early Stage Breast Cancer: A Randomized Phase II Clinical Trial.

Purpose To compare the safety and efficacy of US-guided percutaneous radiofrequency ablation (RFA) as a local treatment for breast cancer with that of lumpectomy. Materials and Methods A prospective, randomized open-label phase II clinical trial (clinicaltrials.gov identification number NCT02281812) was conducted in a single institution from 2013 to 2017. Women with invasive ductal carcinoma of the breast measuring 2 cm or smaller were randomly assigned to receive RFA or lumpectomy alone (control group). Margin status at surgery, tumor cell viability after RFA (with nicotinamide adenine dinucleotide [NADH] and cytokeratin 18 [CK18] staining), cosmetic results, adverse events, and local recurrences were evaluated with univariable and multivariable analyses. Results Forty subjects (20 in the RFA group and 20 in the lumpectomy group) were evaluated. The mean participant age was 64 years (range, 46-86 years). NADH and CK18 staining demonstrated absence of tumor cell viability after RFA with at least one of the two techniques. The surgical margins were positive in 11 of the 20 participants in the lumpectomy group (55%) and four of the 20 in the RFA group (20%) (P = .02). Median follow-up was 25 months (range, 1-83 months). Local breast inflammation after surgery was higher in the RFA group than in the lumpectomy group (40% [eight of 20 participants] vs 5% [one of 20 participants], respectively; P = .01). Local infection occurred in three participants who underwent RFA (two of whom had undergone partial irradiation of the breast). None of the participants in the control group developed local infection. No participants had recurrence or the need for a second surgery during the study period. Conclusion This preliminary study showed that radiofrequency ablation was effective for local tumor control and that tumor-free margins were obtained more often with radiofrequency ablation than with lumpectomy. Surgical excision after radiofrequency ablation was infrequently associated with local infection. © RSNA, 2018 Online supplemental material is available for this article.

Feasibility, accuracy and prognosis of sentinel lymph node biopsy before neoadjuvant therapy in breast cancer. A prospective study.

BACKGROUND AND OBJECTIVE: It remains controversial whether sentinel lymph node biopsy (SLNB) should be performed before or after neoadjuvant therapy (NAT). We aimed to evaluate the feasibility and accuracy of SLNB before NAT at a single institution, and to determine its relation to patient prognosis. METHODS: A prospective study of T1c-T2-T3 N0 breast cancer patients, after ultrasound examination, who underwent SLNB prior to NAT. Overall, disease-specific and disease-free survival were calculated by Kaplan-Meier curves. RESULTS: SLNB before NAT was performed in 123 patients from December 2006 to May 2014. The identification rate was 100%. SLNB was positive in 42.3% of cases (27.6% macrometastases). NAT was chemotherapy in 88.6% of cases and endocrine-therapy in 11.4%. Lymphadenectomy was avoided in 72.4% of cases. Median follow-up was 40 months (range 8-100). Overall and disease-free survival was 90.2% and 88.6% respectively.SLN involvement was not related to patient outcome (p 0.72); however there were significant differences in survival according to molecular-like subtypes (p < 0.025) and NAT response (p < 0.0001). CONCLUSIONS: SLNB prior to NAT is an accurate method of axillary staging associated with a high identification rate. It avoided lymphadenectomy in more than 70% of patients. SLN involvement did not worsen the prognosis in our cohort.

Human papillomavirus infection in HIV-1 infected women in Catalonia (Spain): implications for prevention of cervical cancer.

BACKGROUND: High-risk human Papillomavirus infection is a necessary factor for cervical squamous intraepithelial lesions and invasive cervical cancer. In HIV-1-infected women, HPV infection is more prevalent and a higher risk of cervical cancer has been identified. We aimed to calculate the prevalence of infection by HR-HPV, determine the factors associated with this infection and abnormal cytology findings and to describe the history of cervical cancer screening in HIV-1-infected women. METHODS: We enrolled 479 HIV-1-infected women from the PISCIS cohort. Each patient underwent a gynecological check-up, PAP smear, HPV AND Hybrid capture, HPV genotyping, and colposcopy and biopsy, if necessary. We applied questionnaires to obtain information on sociodemographic, behavioral, clinical, and cervical screening variables. We present a cross-sectional analysis. RESULTS: Median age was 42 years. The prevalence of HR-HPV infection was 33.2% and that of high-grade squamous intraepithelial lesions (HSIL) was 3.8%. The most common genotypes were 16(23%), 53(20.3%), and 52(16.2%). The factor associated with HR-HPV infection was age <30 years (odds ratio[OR],2.5; 95%confidence interval[CI],1.1-5.6). The factors associated with the presence of HSIL or low-grade squamous intraepithelial lesions (LSIL) were CD4T-lymphocyte count <200 cells/mm(3) versus >500 cells/mm(3) (OR,8.4; 95%CI,3.7-19.2), HIV-1 viral load >10,000 copies/mL versus <400 copies/mL (OR,2.1; 95%CI,1.0-4.4), and use of oral contraceptives (OR,2.0; 95%CI,1.0-3.9). Sixty percent of HIV-1-infected women had had one Pap smear within the last 2 years. CONCLUSIONS: The high prevalence of HPV infection and cervical lesions in the HIV-1-infected population in Catalonia, as well as the low coverage and frequency of screening in this group, means that better preventive efforts are necessary and should include vaccination against HPV, better accessibility to screening programs, training of health care professionals, and specific health education for HIV-1-infected women.
