Efficacy of chemotherapy according to BRCA status in patients with high-grade serous ovarian carcinoma at first platinum-sensitive relapse.

OBJECTIVE: Chemotherapy for high-grade serous ovarian cancers in platinum-sensitive relapse includes carboplatin/paclitaxel, carboplatin/gemcitabine, and carboplatin/pegylated liposomal doxorubicin. According to in vitro data, BRCA mutated patients are sensitive to replicative stress agents but BRCA status is not yet used for the choice of chemotherapy at relapse. Our aim was to assess these doublets according to BRCA status in first platinum-sensitive relapse. METHODS: The ESME ovarian cancer database comprises a multicenter retrospective cohort of patients with ovarian cancer treated in French cancer centers between January 2011 and December 2017. Patients with high-grade serous ovarian cancers at first platinum-sensitive relapse who received one of these doublets were included. The objective was to compare progression-free survival of each chemotherapy doublet according to BRCA status. RESULTS: Among the 10 263 patients in the database, 1539 patients had a first platinum-sensitive relapse: 825 BRCA wild type patients (53.6%) and 304 BRCA mutated patients (19.8%) (7 patients had a homologous recombination mutation and BRCA status was unkown for 403 patients). Median progression-free survival was longer in BRCA mutated patients than in BRCA wild type patients when receiving carboplatin/pegylated liposomal doxorubicin without maintenance treatment (15.8 vs 11.8 months; p<0.001). In contrast, we observed no difference in patients treated with carboplatin/paclitaxel (14.6 vs 14.3 months, respectively; p=0.70) or in those treated with carboplatin/gemcitabine (12.0 vs 9.8 months, respectively; p=0.18). In BRCA wild type patients without maintenance, better progression-free survival occurred with carboplatin/paclitaxel (median progression-free survival 14.3 months) than with carboplatin/gemcitabine and carboplatin/pegylated liposomal doxorubicin (9.8 and 11.8 months, respectively; p=0.017). In BRCA mutated patients without maintenance, there was no difference between the three doublets (median progression-free survival of 14.6, 12.0, and 15.8 months with carboplatin/paclitaxel, carboplatin/gemcitabine, and carboplatin/pegylated liposomal doxorubicin, respectively; p=0.40). CONCLUSION: While treatment with carboplatin/paclitaxel, carboplatin/gemcitabine, and carboplatin/pegylated liposomal doxorubicin shows comparable efficacy in BRCA mutated patients, treatment with carboplatin/paclitaxel appears to be more effective than carboplatin/gemcitabine and carboplatin/pegylated liposomal doxorubicin in BRCA wild type patients with high-grade serous ovarian cancers at first platinum-sensitive relapse.

Optimal timing of interval debulking surgery for advanced epithelial ovarian cancer: A retrospective study from the ESME national cohort.

OBJECTIVE: Interval debulking surgery is recommended after 3-4 cycles (standard IDS) of neoadjuvant chemotherapy (NACT) for epithelial ovarian cancer (EOC) not able to received upfront complete debulking surgery. However, real world practices frequently report performing IDS after ≥5 NAC cycles (delayed IDS). The aim of this work was to evaluate the impact on survival of the number of NACT cycles before IDS. METHODS: We identified from a French national database, women with newly diagnosed EOC who underwent IDS from January 2011 to December 2016. Progression free survival (PFS) and overall survival (OS) were compared using Cox model with adjustments for confounding factors provided by two propensity score methods: inverse probability of treatment weighting (IPTW) and matched-pair analysis. RESULTS: 928 patients treated by IDS for which our propensity score could be applied were identified. After a median follow-up of 49.0 months (95% CI [46.0;52.9]); from the IPTW analysis, median PFS was 17.6 months and 11.5 months (HR = 1.42; CI 95% [1.22-1.67]; p < 0.0001); median OS was 51.2 months and 44.3 months (HR = 1.29; CI 95% [1.06-1.56]; p = 0.0095) for the standard and delayed IDS groups. From the matched-pair analysis (comparing 352 patients for each group), standard IDS was associated with better PFS (HR = 0,77; CI 95% [0.65-0.90]; p = 0.018) but not significantly associated with better OS (HR = 0,84; CI 95% [0.68-1,03]; p = 0.0947). CONCLUSIONS: Carrying IDS after ≥5 NACT cycles seems to have a negative effect on patients survival. The goal of IDS surgery is complete resection and should not be performed after >3-4 NACT cycles.

Clinicopathological characterization of a real-world multicenter cohort of endometrioid ovarian carcinoma: Analysis of the French national ESME-Unicancer database.

BACKGROUND: Prognostic significance of endometrioid epithelial ovarian cancer (EOC) is controversial. We compared clinical, pathological, and biological features of patients with endometrioid and serous EOC, and assessed the independent effect of histology on outcomes. METHODS: We conducted a multicenter retrospective analysis of patients with EOC selected from the French Epidemiological Strategy and Medical Economics OC database between 2011 and 2016. Our main objective was to compare overall survival (OS) in endometrioid and serous tumors of all grades. Our second objectives were progression-free survival (PFS) and prognostic features. RESULTS: Out of 10,263 patients included, 3180 cases with a confirmed diagnosis of serous (N = 2854) or endometrioid (N = 326) EOC were selected. Patients with endometrioid histology were younger, more often diagnosed at an early stage, with lower-grade tumors, more frequently dMMR/MSI-high, and presented more personal/familial histories of Lynch syndrome-associated cancers. BRCA1/2 mutations were more frequently identified in the serous population. Endometrioid patients were less likely to receive chemotherapy, with less bevacizumab. After median follow-up of 51.7 months (95CI[50.1-53.6]), five-year OS rate was 81% (95CI[74-85]) in the endometrioid subgroup vs. 55% (95CI[53-57] in the serous subset (p < 0.001, log-rank test). In multivariate analyses including [age, ECOG-PS, FIGO, grade, and histology], the endometrioid subtype was independently associated with better OS (HR = 0.38, 95CI[0.20-0.70], p= 0.002) and PFS (HR = 0.53, 95CI[0.37-0.75], p < 0.001). CONCLUSIONS: Clinicopathological features at diagnosis are not the same for endometrioid and serous EOC. Endometrioid histology is an independent prognosis factor in EOC. These observations suggest the endometrioid population requires dedicated clinical trials and management.

DPD status and fluoropyrimidines-based treatment: high activity matters too.

BACKGROUND: Dihydropyrimidine dehydrogenase (DPD) status is an indicator of a marked risk for toxicity following fluoropyrimidine (FP)-based chemotherapy. This notion is well-established for low DPD status but little is known about the clinical impact of high DPD activity. This study examined the possible link between high intrinsic lymphocytic DPD activity and overall survival, progression free survival and response to FP-based treatment in patients treated in our institution. METHODS: Lymphocytic DPD activity was assessed in a group of 136 patients receiving FP-based chemotherapy from 2004 to 2016. There were 105 digestive (77.2%), 24 breast (17.6%) and 7 head and neck cancers (5.2%). Cox or logistic regression models were applied with adjustment on all confounding factors that could modify OS, PFS or response. All models were stratified on the three cancer locations. A cut-off for DPD activity was assessed graphically and analytically. RESULTS: An optimal cut-off for DPD activity at 0.30 nmol/min/mg protein was identified as the best value for discriminating survivals and response. In multivariate analysis, individual lymphocytic DPD activity was significantly related to overall survival (p = 0.013; HR: 3.35 CI95%[1.27-8.86]), progression-free survival (p < 0.001; HR: 3.15 CI95%[1.75-5.66]) and response rate (p = 0.033; HR: 0.33 CI95%[0.12-0.92]) with a marked detrimental effect associated with high DPD activity. CONCLUSIONS: DPD status screening should result in a two-pronged approach with FP dose reduction in case of low intrinsic DPD and, inversely, an increased FP dose for high intrinsic DPD. In a context of personalized FP-based treatment, this innovative strategy needs to be prospectively validated.

Is there a role for a handheld gamma camera (TReCam) in the SNOLL breast cancer procedure?

BACKGROUND: Sentinel node and occult lesion localization (SNOLL) calls for a combination of two specific procedures: intraoperative detection of sentinel lymph node (SLN) and radio-guided occult lesion localization (ROLL). The safety and benefits of radio-guided localization in the surgical treatment of non-palpable breast cancer have been confirmed. The aim of this study was to evaluate the potential role for an intra-operative handheld tumor resection gamma camera (TReCam) in SNOLL procedures. METHODS: Fifteen patients were enrolled. The SNOLL procedure was performed in all patients with conventional lymphoscintigraphy (LS). TReCam was used to obtain nuclear imaging in the operating theater. Concordance between LS and TReCam images, duration of use and assessment of difficulties in data acquisition with TReCam were reported. RESULTS: Concordance for tumor localization between single-detector gamma probe and TReCam was excellent (15/15). The number of radioactive SLNs visualized between LS and TReCam was equivalent in 53.3% of cases (8/15). TReCam was considered to be very easy-to-use (12/15) or easy-to-use (3/15). Average duration of acquisition with TReCam was 4 minutes and 45 seconds for the SLN procedure, and 2 minutes and 10 seconds for lumpectomy. CONCLUSIONS: This study suggests that TReCam is easy-to-use and does not increase operative time. Its exact role in radio-guided surgery needs to be clearly defined in a larger study. However, its usefulness and benefits in radio-guided breast surgery seem to be promising.

Surgical treatment of secondary lymphedema of the upper limb by stepped microsurgical lymphaticovenous anastomoses.

OBJECTIVE: The incidence of lymphedema following treatment for breast cancer ranges between 10 and 50% after complete axillary dissection and gives rise to severe functional discomfort in patients. Results of lymphaticovenous anastomoses (LVA) in surgical treatment of lymphedema appear to be favorable. However, the available literature on this topic is scarce, often with short follow-up times. The aim of this study is to analyze the results of LVA on 31 patients and to review the existing literature. PATIENTS AND METHODS: This study comprised 31 female patients presenting lymphedema of the upper limb following treatment for breast cancer for which surgical treatment was given by microsurgery consisting of three stepped LVA performed in an outpatient setting. RESULTS: The post-LVA arm circumference was measured at three levels (wrist, forearm, and arm) in 31 female patients. Mean follow-up time was 12.8 months. Reduction in the circumference was 22.5, 21.32, and 30.2%, respectively, in the wrist, forearm, and arm. Functional improvement was observed in the majority (84%) of patients ranging from moderate to substantial. Only 2 patients had no result. The only patients to experience recurrence were those with a high level of lymphedema. CONCLUSION: The review of the current literature and the present study revealed modest results in terms of decreased excess volume, although a major improvement in function points to LVA as a useful technique in this indication. Progress in imaging techniques has enhanced the results achieved with this procedure, although further studies on recurrence rates are needed with a follow-up greater than 1 year.

Evaluation and Selection of Quality Indicators for the Management of Endometrial Cancer.

OBJECTIVE: The aim of this study was to evaluate 36 quality indicators (QIs) for monitoring the quality of care of uterine cancer to be implemented in the EFFECT (effectiveness of endometrial cancer treatment) project. METHODS: The 36 QIs were evaluated in the first 10 patients diagnosed with endometrial cancer and managed in 14 French hospitals in 2011. To assess the status of each QI, a questionnaire detailing the 36 QIs was sent to each hospital, and the information was cross-checked with information from the multidisciplinary staff meeting, surgical reports, and pathological reports. The QIs were evaluated in terms of measurability and improvability. The remaining QIs were evaluated with a multiple correspondence analysis to highlight the interrelationships between qualitative variables describing a population. RESULTS: Thirteen of the 14 institutions responded to the survey for a total of 130 patients. Twenty-five of the 36 QIs affected less than 80% of the patients. Thirteen QIs were found not to be improvable because they reached more than 95% of the theoretical target. Finally, 5 QIs concerning more than 80% of the patients were found to be improvable. The multiple correspondence analysis finally identified 3 dimensions-outcome, safety, and perioperative management-that included the 5 QIs. CONCLUSIONS: In the present study, 5 of the 36 QIs suggested by the EFFECT project seem to be sufficient to report on the quality of endometrial cancer management. Further studies are needed to correlate the information provided by those 5 questions and the relevant outcomes reflecting quality of care in endometrial cancer.

Clinical nomogram to predict bone-only metastasis in patients with early breast carcinoma.

BACKGROUND: Bone is one of the most common sites of distant metastasis in breast cancer. The purpose of this study was to combine selected clinical and pathologic variables to develop a nomogram that can predict the likelihood of bone-only metastasis (BOM) as the first site of recurrence in patients with early breast cancer. METHODS: Medical records of patients with non-metastatic breast cancer were retrospectively collected. On the basis of the analysis of patient and tumour characteristics using the Cox proportional hazards regression model, a nomogram to predict BOM was constructed for a 4175-patient-training cohort. The nomogram was validated in an independent cohort of 579 patients. RESULTS: Among 4175 patients with non-metastatic breast cancer, 314 developed subsequent BOM. Age, T classification, lymph node status, lymphovascular space invasion, and hormone receptor status were significantly and independently associated with subsequent BOM. The nomogram had a concordance index of 0.69 in the training set and 0.73 in the validation set. CONCLUSIONS: We have developed a clinical nomogram to predict subsequent BOM in patients with non-metastatic breast cancer. Selection of a patient population at high risk for BOM could facilitate research of more specific staging approaches or the selective use of bone-targeted therapy.

Untreated highly viraemic pregnant women from Asia or sub-Saharan Africa often transmit hepatitis B virus despite serovaccination to newborns.

BACKGROUND & AIMS: Mother-to-child (MTC) hepatitis B virus (HBV) transmission has been mainly studied in Asia. The geographical origins of women and HBV genotypes differ in Europe. The aims were to determine the rate and risk factors of MTC HBV transmission from women with high HBV DNA loads in a maternity hospital in Paris, France. METHODS: Retrospective study of HIV-negative, HBs Ag-positive pregnant women with HBV DNA loads above 5 Log10 I.U/ml who were not given lamivudine or tenofovirDF during pregnancy between 2004 and 2011. RESULTS: Among 11 417 pregnant women, 437 (4%) showed a positive HBs Ag. Among these women, 52 had HBV DNA loads above 5 Log10 I.U/ml: 41, 10 and 1 born in Asia, sub-Saharan Africa and Europe respectively. Among the 52 women, 40 were eligible for the analysis: no antiviral therapy during pregnancy; children over 9 months old. Twenty-eight (70%) women were assessed, corresponding to 41 childbirths. Eleven children (27%) had positive HBs Ag, 14 (34%) had positive HBc and HBs Ab, 16 (39%) had positive HBs Ab only. The risk of having positive HBs Ag, according to maternal HBV DNA loads, was 14% for HBV DNA loads less or equal to 8 Log10 I.U/ml, 42% for HBV DNA loads over 8 Log10 I.U/ml, P = 0.04, but not related to the women's origin, HBV genotype. CONCLUSIONS: This study confirms that serovaccination does not fully protect newborns from MTC HBV transmission, when maternal HBV DNA loads exceed 5 Log10 I.U/ml, regardless of the women's origin or HBV genotype.

Direct Comparison of Logistic Regression and Recursive Partitioning to Predict Lymph Node Metastasis in Endometrial Cancer.

OBJECTIVE: The purpose was to compare logistic regression model (LRM) and recursive partitioning (RP) to predict lymph node metastasis in early-stage endometrial cancer. METHODS/MATERIALS: Three models (1 LRM and 2 RP, a simple and a complex) were built in a same training set extracted from the Surveillance, Epidemiology, and End Results database for 18,294 patients who underwent hysterectomy and lymphadenectomy for stage I or II endometrial cancer. The 3 models were validated in a same validation set of 499 patients. Model performance was quantified with respect to discrimination (evaluated by the areas under the receiver operating characteristics curves) and calibration. RESULTS: In the training set, the areas under the receiver operating characteristics curves were similar for LRM (0.80 [95% confidence interval [CI], 0.79-0.81]) and the complex RP model (0.79 [95% CI, 0.78-0.80]) and higher when compared with the simple RP model (0.75 [95% CI, 0.74-0.76]). In the validation set, LRM (0.77 [95% CI, 0.75-0.79]) outperformed the simple RP model (0.72 [95% CI, 0.70-0.74]). The complex RP model had good discriminative performances (0.75 [95% CI, 0.73-0.77]). Logistic regression model also outperformed the simple RP model in terms of calibration. CONCLUSIONS: In these real data sets, LRM outperformed the simple RP model to predict lymph node metastasis in early-stage endometrial cancer. It is therefore more suitable for clinical use considering the complexity of an RP complex model with similar performances.

Individual xenograft as a personalized therapeutic resort for women with metastatic triple-negative breast carcinoma.

A localized left breast ductal invasive triple-negative breast carcinoma (TNBC) was diagnosed in a 44-year-old woman. After surgery, she was treated with chemotherapy and radiation therapy in accordance with national guidelines. At the end of treatment, she had local and metastatic relapse with multiple sub-diaphragmatic lymph nodes.

Xpert GBS assay for rapid detection of group B streptococcus in gastric fluid samples from newborns.

The Xpert GBS real-time PCR assay was applied to gastric fluid samples from 143 newborns, and it detected group B streptococcus (GBS) within 1 h for 16 (11.2%) cases, while microscopic examination detected only 2 cases. The sensitivity and specificity of the Xpert GBS were 80% and 100%, respectively, with regard to 20 cases of GBS colonization or infection. Concordance of Xpert GBS results versus culture was 92.3%. This test detects in a timely manner newborns at risk for invasive GBS disease.

A suggested modification to FIGO stage I endometrial cancer.

OBJECTIVE: FIGO stage I endometrial cancers are divided into two substages, regardless of the presence or absence of lymphovascular space invasion (LVSI). The aim of this study was to investigate whether stratification based on the LVSI status would better predict mortality. METHODS: Using a multicentric database, we identified patients who underwent endometrial cancer operations between 2000 and 2010. The staging performance was quantified with respect to discrimination. RESULTS: The study cohort included 508 patients (198 with LVSI-positive tumors and 310 with LVSI-negative tumors). The survival difference between the stage I patients with LVSI-positive and LVSI-negative tumors was highly significant (81% and 97%, respectively P=.009), whereas the difference between the stage I patients with tumors invading greater or less than half of the myometrium was not (87% and 96%, respectively P=0.09). The 5-year OS rates for the patients with LVSI-negative tumors invading less than half of the myometrium, with LVSI-negative tumors invading more than half of the myometrium and with LVSI-positive invading more than or less than half of the myometrium were 98%, 95%, and 81%, respectively (P=.03). Separating the LVSI-negative and LVSI-positive tumors would improve discrimination (concordance index, 77% vs. 75%, respectively, using the actual staging system). CONCLUSION: A LVSI-positive status has a significantly worse prognosis. In this study, the distinction by LVSI status appears to be more relevant than the distinction between stages IA and IB for predicting survival in stage I endometrial cancer. This difference in prognosis would favor restaging these two entities.

The exportability of the ACOSOG Z0011 criteria for omitting axillary lymph node dissection after positive sentinel lymph node biopsy findings: a multicenter study.

PURPOSE: To determine the exportability of the criteria defined by the American College of Surgeons Oncology Group Z0011 trial for selecting patients who are eligible for omitting completion axillary lymph node dissection (cALND) after a positive sentinel lymph node (SLN) biopsy result and to investigate whether not following the Z0011 criteria might affect patient outcomes. METHODS: From a multicenter database, we selected 188 patients with positive SLNs and then excluded patients with positive SLNs on immunohistochemistry only. We retrospectively applied the Z0011 criteria and grouped the patients as eligible or ineligible for omitting cALND. The eligible group was compared with the cohort included in the Z0011 trial and with the ineligible group. Kaplan-Meier survival curves were calculated for each group, and univariate analyses assessed associations between the groups and clinicopathological variables. RESULTS: The final analysis involved 125 patients with positive SLNs. Eighty-seven patients (69.6 %) were potentially eligible for omitting cALND. The estrogen receptor status, T stage, grade, and number of positive non-SLNs were not statistically different between the eligible group and the Z0011 cohort. The ineligible group had significantly more positive non-SLNs (P = 0.01) and a lower 5-year overall survival rate than the eligible group (P < 0.001). CONCLUSIONS: The similarity of clinical characteristics between the Z0011 trial cohort and our eligible group confirms the exportability of these criteria to another population. The worse prognosis of patients who did not meet the Z0011 criteria suggests prudence before disregarding or enlarging broadening the indications for omitting cALND.

Impact of lymphovascular space invasion on a nomogram for predicting lymph node metastasis in endometrial cancer.

OBJECTIVE: The aim of this study was to evaluate the impact of lymphovascular space invasion (LVSI) on nomogram-based predictions of lymph node (LN) metastasis in endometrial cancer. METHODS: The data from 485 patients with presumed stage I or II endometrial cancer who underwent hysterectomy and lymphadenectomy were analyzed. Calibration curves were designed and compared for three different subgroups: LVSI-positive tumors (n=113), LVSI-negative tumors (n=213) and LVSI-undetermined tumors (n=159). RESULTS: In the entire population, the nomogram showed good discrimination with an area under the receiver operating characteristic curve (AUC) of 0.80 and was well calibrated. In the subgroup analyses, in LVSI-positive, LVSI-negative and LVSI-undetermined patients, the nomogram was not well calibrated (p of the U index of 0.028, 0.087 and 0.011, respectively) with underestimation in LVSI-positive patients and overestimation in LVSI-negative and LVSI-undetermined patients of LN metastasis. In the univariate analysis and after adjusting for the LN metastasis probability provided by the nomogram, LVSI-positive tumors were associated with an increased risk for LN metastasis compared with LVSI-negative tumors (RR=7.29 [3.87-13.7] and 5.04 [2.30-11.08], respectively). In contrast, the univariate analysis and after adjusting for the LN metastasis probability provided by the nomogram showed that LVSI-undetermined tumors were not associated with an increased risk for LN metastasis compared with LVSI-negative tumors (RR=0.73 [0.32-1.69] and 1.26 [0.47-3.37], respectively). CONCLUSIONS: Our results suggested that LVSI should be considered to be an independent risk factor for LN metastasis. In this multicenter study, the risk for LN metastasis is similar when the LVSI is negative or is not detailed in the pathological report.

Placental vascularity and resorption delay after conservative management of invasive placenta: MR imaging evaluation.

OBJECTIVES: To assess the potential of magnetic resonance (MR) imaging in evaluating placental vascularity and predicting placental resorption delay after conservative management of invasive placenta. METHODS: MR examinations of 23 women with conservative management of invasive placenta were reviewed. Twelve women had pelvic embolisation because of postpartum haemorrhage (Group 1) and 11 had no embolisation (Group 2). Comparisons between the two groups were made with respect to the delay for complete placental resorption at follow-up MR imaging and degree of placental vascularity 24 h after delivery on early (30s) and late (180 s) phase of dynamic gadolinium chelate-enhanced MR imaging. RESULTS: The median delay for complete placental resorption in the cohort study was 21.1 weeks (range, 1-111 weeks). In Group 1, the median delay for complete placental resorption was shorter than in Group 2 (17 vs 32 weeks) (P = 0.036). Decreased placental vascularity on the early phase was observed in Group 1 by comparison with Group 2 (P = 0.003). Significant correlation was found between the degree of vascularity on early phase of dynamic MR imaging and the delay for complete placental resorption (r = 0.693; P < 0.001). CONCLUSIONS: MR imaging provides useful information after conservative management of invasive placenta and may help predict delay for complete placental resorption.

Delayed hysteroscopic resection of retained tissues and uterine conservation after conservative treatment for placenta accreta.

BACKGROUND: Conservative management of both the uterus and the abnormal placenta, which is left inside the uterus at the time of delivery, is one option of placenta accreta management. Complete elimination of the residual placenta is the main challenge of this procedure. AIM: To report the role, efficacy and safety of hysteroscopic resection in women presenting with severe pelvic pain and chronic intra-uterine retention after conservative treatment of placenta accreta. MATERIAL AND METHODS: Four consecutive women who were treated with hysteroscopic resection of retained tissues after conservative treatment of placenta accreta or percreta at the time of delivery. Clinical files and surgical procedures were reviewed. All procedures were performed because of chronic pelvic pain and the absence of a complete spontaneous placental elimination. RESULTS: All procedures were successful and uneventful. The uterus was conserved with a complete disappearance of the symptoms in the four women, and two of them became pregnant. CONCLUSION: Hysteroscopic resection seems effective and safe for shortening the duration of placental elimination after conservative treatment in women with severe pelvic pain due to uterine retention. This approach allows conserving the uterus and future fertility.

[Breast cancer surgery]. / Chirurgie du cancer du sein.

The surgery for breast cancer is frequently the first step in a multi-disciplinary care. It allows for local control, but also to establish crucial prognostic factor indicating potential adjuvant therapy. The current trend s towards de-escalation of surgical treatment for reducing the functional and aesthetic morbidity. At the local level, this de-escalation has been made possible by performing most often breast conservative surgery because of the development of oncoplastic techniques, but also because of neoadjuvant chemotherapy. At the axillary level, the reduction of morbidity has been made possible by the advent of the sentinel node biopsy which is more and more indicated year after year.

Breast Cancer and SARS-Cov2: Lessons from a Pandemic.

BACKGROUND/AIM: The COVID-19 pandemic introduced drastic containment measures, which had a direct impact on breast cancer management. During the first wave, a delay in care and a decrease in new consultation numbers was observed. It would be interesting to study the resulting long-term consequences on breast cancer presentation and time to first treatment. PATIENTS AND METHODS: This retrospective cohort study was conducted at the surgery Department of the Anti-Cancer Center of Nice, France. Two periods of 6 months were compared: a pandemic period from June to December 2020 (after the end of the first wave), and a control period one year earlier. The primary endpoint was to measure the time to care access. The patients and cancer characteristics and the management type were also compared. RESULTS: A total of 268 patients underwent diagnosis for breast cancer in each period. The time from biopsy to consultation was shortened after the containment was lifted (16 days vs. 18 days, p=0.024). The time between first consultation and treatment was unchanged between the two periods. The tumor size was larger in the pandemic period (21 mm vs. 18 mm, p=0.028). The clinical presentation was different: 59.8% of patients consulted for a palpable mass in the pandemic period, vs. 49.6% in the control period (p=0.023). There was no significant change in therapeutic management. The use of genomic testing was significantly increased. The number of breast cancer cases diagnosed decreased by 30% during the first COVID-19 lockdown. Even though a rebound was expected after the first wave, the number of consultations for breast cancer remained constant. This finding shows the fragility of screening adherence. CONCLUSION: It is necessary to reinforce education in the face of crises that may be repeated. Management of breast cancer did not change, which is a reassuring aspect regarding the care pathway in anticancer centers.

SENODAY: A New Perspective of Handling Breast Cancer.

BACKGROUND: To evaluate the feasibility of a same day breast cancer diagnosis and management protocol, consequently decreasing time to treatment and immediately reassuring patients with benign diagnosis. MATERIALS AND METHODS: A total of 60 women underwent breast exam during SENODAY in our cancer center between January 2020 and December 2022. Patients are first seen by a breast surgeon who mentions whether the patient's history and physical exam are suspicious of malignancy. Patients are then sent to the radiologist who performs a complete radiologic assessment, classifies the lesions, and performs a biopsy when necessary. The specimen is sent to the pathologist who uses the imprint cytology technique to obtain a preliminary diagnosis. Effective counseling is established in case of breast cancer diagnosis. RESULTS: Among 60 women, 25 patients were reassured by breast imaging and 35 underwent histopathological analysis (17 patients with a 1-day protocol and 18 with the standard definitive technique). Clinical examination was found to have a sensitivity of 100% and a specificity of 89.47%. The positive predictive value was 80 % and the negative predictive value was 100%. However, we did not find a strong correlation between imaging and definitive pathology. Moreover, on imprint cytology, sensitivity, specificity, PPV, and NPV were 100%. Finally, the mean time-to-treat was 28.6 days. CONCLUSIONS: SENODAY reassured 68.3% of patients. It also offered effective counseling and a treatment plan to newly diagnosed breast cancer patients within 1 day. Same day histological diagnosis by imprint cytology is effective and feasible with an excellent accuracy.
