[For which patients could we consider de-escalation in the management of ductal carcinomas in situ?] / Pour quelles patientes peut-on envisager une désescalade dans la prise en charge des carcinomes canalaires in situ ?

Ductal carcinomas in situ (DCIS) of the breast account for 85% to 90% of breast cancer in situ. Current recommendations for the management of DCIS in France are based on surgical excision of the lesions, lumpectomy in healthy margins (margins of excision≥2mm) or mastectomy in case of extensive lesions. Radiation therapy is recommended after conservative surgical treatment. However, it seems relevant for some patients to discuss the benefit of a therapeutic de-escalation. Indeed, it has been reported that radiotherapy has no major impact on overall survival and that its interest could be discussed in the low-risk situations of invasive recurrence for which surgery alone could be sufficient, subject to sufficient margins. These questions call for the precise definition of low risk populations and to clarify the importance of taking into account decision support tools and new molecular markers. The place of scores like that of the University of Southern California - Van Nuys, and that of genomic tests such as the Oncotype test© DX DCIS (DCIS score) need to be specified. The expected results of several prospective studies could go in the direction of a significant therapeutic de-escalation for the management of DCIS in the years to come. In the meantime, however, it is advisable to remain cautious and the inclusion of patients in clinical trials should be favored.

[CO2 LASER for the treatment of vaginal symptoms of genitourinary syndrome of menopause]. / Place du LASER au CO2 pour le traitement des symptômes vaginaux du syndrome génito-urinaire de la ménopause.

Genitourinary syndrome of menopause (GSM) brings together a collection of signs including vaginal dryness, burning sensation and itching discomfort as well as deterioration of sexual health, dysuria, urgenturia and repeated urinary infections and may be responsible for a significant impairment of quality of life in symptomatic postmenopausal women. The management of GSM therefore represents a public health issue. Systemic or local hormonal treatments are frequently offered, as well as non-hormonal treatments. The existence of contraindications to hormonal treatments and the constraints of using local treatments lead us to propose other therapeutic options. CO2 LASER is now part of the therapeutic arsenal for the treatment of vaginal dryness in the context of GSM. There is a growing interest in this technique, especially for women who have a contraindication to hormonal therapy, as it is a globally effective, long-acting alternative with very little adverse effect. Current evidence suggests that this tool could provide a quality of life benefit to many patients with minimal side effect exposure, if used in the respect of its indications and implementation protocols. However, clinical data based on high-level therapeutic trials remain absolutely essential for this treatment to be validated and recommended by health professionals.

Improving the clinical management of women with borderline tumours: a recurrence risk scoring system from a French multicentre study.

OBJECTIVE: To develop a risk scoring system (RSS) for predicting recurrence in women with borderline ovarian tumours (BOTs). DESIGN: Cohort study of women with BOTs. SETTING: French multicentre tertiary care centres. POPULATION: A cohort of 360 women with BOTs who received primary surgical treatment between January 2000 and December 2013. METHODS: Clinical and pathological factors affecting recurrence in women with BOTs. MAIN OUTCOME MEASURE: The development of a model for the prediction of recurrence in women with BOTs. RESULTS: Overall the recurrence rate was 20.0% (72/360). Recurrence was associated with five variables: age < 45 years; preoperative serum tumour marker CA125 > 150 IU/mL; a serous histological subtype; International Federation of Gynecology and Obstetrics (FIGO) stage other than IA; and ovarian surgery other than bilateral salpingo-oophorectomy (BSO; i.e. cystectomy and unilateral salpingo-oophorectomy). These variables were included in the RSS and assigned scores ranging from 0 to 6. The discrimination of the RSS was 0.82 (95% confidence interval, 95% CI 0.79-0.85). A total score of 8 points corresponded to the optimal threshold of the RSS, with a rate of recurrence of 11.8% (35/297) and 58.7% (37/63) for women at low risk (<8 points) and women at high risk (≥8 points), respectively. The diagnostic accuracy was 85.0%. CONCLUSIONS: This study shows that the risk of BOT recurrence can be accurately predicted so that women at high risk can benefit from adapted surgical treatment. TWEETABLE ABSTRACT: Our RSS permitted women with BOTs at low risk to be distinguished from women with BOTs at high risk of recurrence.

Influence of histological subtypes on the risk of an invasive recurrence in a large series of stage I borderline ovarian tumor including 191 conservative treatments.

BACKGROUND: The overall prognosis of stage I borderline ovarian tumors (BOT) is excellent but a small percentage of patients die to their disease. The prognostic factors for such a rare event are still not clearly defined. The aim of this study was to determine these factors for recurrence per se and recurrence in the form of invasive carcinoma in a large series of stage I tumors. METHODS: A retrospective review of patients with BOT. Three inclusion criteria were defined: (i) a centralized histological review; (ii) macroscopic stage I tumors; (iii) exclusion of metastatic disease to the ovaries. RESULTS: From 2000 to 2010, 254 patients fulfilled inclusion criteria [140 had mucinous BOT (MBOT) and 114 a serous BOT (SBOT)], and 191 had undergone conservative management. After a median follow-up of 45 months, 43 patients had developed recurrences (31 borderline and 12 invasive). The risks of recurrences were statistically increased after conservative treatment, particularly after a cystectomy, in patients with stage IB and among patients with incompletely staged tumors. In the subgroup of conservatively treated patients (representing 75% of our population), the risks of recurrences were statistically increased in patients affected by a SBOT, in patients who had undergone a cystectomy, in patients with stage IB disease and in patients with a micropapillary pattern (MPP). MBOT and the presence of a MPP were identified as prognostic factors for invasive disease. CONCLUSIONS: In the present series of BOT with the largest number of patients treated conservatively to date, the presence of a MPP and the mucinous subtype were associated with a higher rate of progression to carcinoma after conservative management. These important results suggest that MBOT belong to a 'high-risk' group likely to develop an invasive recurrence after fertility-sparing surgery in stage I BOT.

[Laparoscopic radical hysterectomy after initial brachytherapy for stage IB1 cervical cancer: feasibility and results]. / Colpohystérectomie élargie par laparoscopie après curiethérapie préopératoire pour cancer du col utérin (stade 1B1) : faisabilité et résultats.

BACKGROUND: The aim of this study was to examine the feasibility and to report the results of laparoscopic radical hysterectomy (LRH) after initial uterovaginal brachytherapy (BT) for stage IB1 cervical cancer. PATIENTS AND METHODS: We retrospectively reviewed in two Comprehensive Cancer Centers patients who had undergone initial BT followed 6 to 8 weeks later by LRH and lymph node dissection. RESULTS: Between 2003 and 2010, 162 patients had undergone LRH. The procedure was feasible using this approach in 160 (98.8%) cases (2 conversions to laparotomy). Eight peroperative complications had occurred. Nineteen patients had nodal involvement. Peri- or postoperative ureteral morbidity had occurred in 10 (6%) patients. Twenty-four (15%) patients had experienced postoperative dysuria. Histologically, only 9 patients had residual cervical disease>5 mm and only 1 patient had parametrial lymphovascular space involvement (associated with nodal spread). No patient had vaginal disease or involved surgical margins. After a median follow-up of 39 months (range, 3-118), 9 patients had relapsed. Five-year overall survival was 95% (88.2%-97.9%). CONCLUSIONS: Radical hysterectomy using a laparoscopic approach is feasible and reproducible after initial BT for stage IB1 cervical cancer and is associated with excellent survival. Morbidity is very close to that reported in patients treated using upfront surgery. In this large series, the morbidity associated with parametrial dissection and the fact that parametrial spread was observed in only 0.6% of the patients suggest that a simple extrafascial hysterectomy is perhaps sufficient in this context.
