RESUMEN
BACKGROUND: We determined the prognostic impact of lymphovascular invasion (LVI) in a large, national, multicenter, retrospective cohort of patients with early breast cancer (BC) according to numerous factors. PATIENTS AND METHODS: We collected data on 17 322 early BC patients treated in 13 French cancer centers from 1991 to 2013. Survival functions were calculated using the Kaplan-Meier method and multivariate survival analyses were carried out using the Cox proportional hazards regression model adjusted for significant variables associated with LVI or not. Two propensity score-based matching approaches were used to balance differences in known prognostic variables associated with LVI status and to assess the impact of adjuvant chemotherapy (AC) in LVI-positive luminal A-like patients. RESULTS: LVI was present in 24.3% (4205) of patients. LVI was significantly and independently associated with all clinical and pathological characteristics analyzed in the entire population and according to endocrine receptor (ER) status except for the time period in binary logistic regression. According to multivariate analyses including ER status, AC, grade, and tumor subtypes, the presence of LVI was significantly associated with a negative prognostic impact on overall (OS), disease-free (DFS), and metastasis-free survival (MFS) in all patients [hazard ratio (HR) = 1.345, HR = 1.312, and HR = 1.415, respectively; P < 0.0001], which was also observed in the propensity score-based analysis in addition to the association of AC with a significant increase in both OS and DFS in LVI-positive luminal A-like patients. LVI did not have a significant impact in either patients with ER-positive grade 3 tumors or those with AC-treated luminal A-like tumors. CONCLUSION: The presence of LVI has an independent negative prognostic impact on OS, DFS, and MFS in early BC patients, except in ER-positive grade 3 tumors and in those with luminal A-like tumors treated with AC. Therefore, LVI may indicate the existence of a subset of luminal A-like patients who may still benefit from adjuvant therapy.

OBJECTIVES: The aim of this study is to describe the current trends of breast reconstruction (BR) and breast oncoplasty (BO) for breast cancer patients in Reunion Island. METHODS: This is a multicenter retrospective descriptive study of all BR and BO surgeries in 2016. We studied the first stage of BR that corresponds to the choice of surgical technique. Patient's age, care center, technique and duration of surgery, complications and their risk factors were reviewed. Patient satisfaction was assessed using the modified BREAST-Q©. RESULTS: In 2016, BR rate over total mastectomy was 47.6% and BO rate was 6.3% over partial mastectomy. Among the 92 patients included, 25 immediate BR were performed (84% in private institution) and 44 delayed BR (67% in public hospital). Although prosthetic techniques were the most used, satisfaction seems to be better with autologous techniques. CONCLUSIONS: The ratio of BR is high in Reunion Island with a wide range of techniques but uneven practice. Conversely, BO's ratio is low and improvement is needed.

BACKGROUND: Omission of completion axillary lymph node dissection (ALND) is a standard practice in patients with breast cancer (BC) and negative sentinel nodes (SNs) but has shown insufficient evidence to be recommended in those with SN invasion. METHODS: A retrospective analysis of a cohort of patients with BC and micrometastases (Mic) or isolated tumour cells (ITCs) in SN. Factors associated with ALND were identified, and patients with ALND were matched to patients without ALND. Overall survival (OS) and recurrence-free survival (RFS) were estimated in the overall population, in Mic and in ITC cohorts. FINDINGS: Among 2009 patients analysed, 1390 and 619 had Mic and ITC in SN, respectively. Factors significantly associated with ALND were SN status, histological type, age, number of SN harvested and absence of adjuvant chemotherapy. After a median follow-up of 60.4 months, ALND omission was independently associated with reduced OS (hazard ratio [HR] 2.41, 90 confidence interval [CI] 1.36-4.27, p = 0.0102), but not with increased RFS (HR 1.21, 90 CI 0.74-2.0, p = 0.52) in the overall population. In matched patients, the increased risk of death in case of ALND omission was found only in the Mic cohort (HR 2.88, 90 CI 1.46-5.69), not in the ITC cohort. The risk of recurrence was also significantly increased in the subgroup of matched Mic patients (HR 1.56, 90 CI 0.90-2.73). INTERPRETATION: A separate analysis of Mic and ITC groups, matched for the determinants of ALND, suggested that patients with Mic had increased recurrence rates and shorter OS when ALND was not performed. Our results are consistent with those of previous studies for patients with ITC but not for those with Mic. Randomised controlled clinical trials are still warranted to show with a high level of evidence if ALND can be safely omitted in patients with micrometastatic disease in SN.

AIM: Sentinel lymph node (SLN) biopsy was recently recommended after prior breast tumour surgery and lymphadenectomy is not the gold standard anymore for nodal staging after a lesion's removal. The purpose of our study was to evaluate the good practices of use of SLN biopsy in this context. PATIENTS AND METHODS: From 2006 to 2012, 138 patients having undergone a surgical biopsy without prior diagnosis of an invasive carcinoma with a definitive histological analysis in favour of this diagnosis were included in a prospective observational multicentric study. Each patient had a nodal staging following SLN biopsy with subsequent systematic lymphadenectomy. RESULTS: The detection rate of SLN was 85.5%. The average number of SLNs found was 1.9. The relative detection failure risk rate was multiplied by 4 in the event of an interval of less than 36 days between the SLN biopsy and the previous breast surgery, and by 9 in the event of using a single-tracer detection method. The false negative rate was 6.25%. The prevalence of metastatic axillary node involvement was 11.6%. In 69% of cases only the SLN was metastatic. The post-operative seroma rate was 19.5%. CONCLUSION: Previous conservative breast tumour surgery does not affect the accuracy of the SLN biopsy. A sufficient interval of greater than 36 days between the two operations could allow to improve the SLN detection rate, although further studies are needed to validate this statement. CLINICAL TRIAL REGISTRATION NUMBER: NCT00293865.

OBJECTIVES: To assess the prognostic factors of T1 and T2 infiltrating lobular breast cancers, and to investigate predictive factors of axillary lymph node involvement. METHODS: This is a retrospective multicentric study, conducted from 1999 to 2008, among 13 french centers. All data concerning patients with breast cancer who underwent a primary surgical treatment including a sentinel lymph node procedure have been collected (tumors was stage T1 or T2). Patients underwent partial or radical mastectomy. Axillary lymph node dissection was done systematically (at the time of sentinel procedure evaluation), or in case of sentinel lymph node involvement. Among all the 8100 patients, 940 cases of lobular infiltrating tumors were extracted. Univariate analysis was done to identify significant prognosis factors, and then a Cox regression was applied. Analysis interested factors that improved disease free survival, overall survival and factors that influenced the chemotherapy indication. Different factors that may be related with lymph node involvement have been tested with univariate than multivariate analysis, to highlight predictive factors of axillary involvement. RESULTS: Median age was 60 years (27-89). Most of patients had tumours with a size superior to 10mm (n=676, 72%), with a minority of high SBR grade (n=38, 4%), and a majority of positive hormonal status (n = 880, 93, 6%). The median duration of follow-up was 59 months (1-131). Factors significantly associated with decreased disease free survival was histological grade 3 (hazard ratio [HR]: 3,85, IC 1,21-12,21), tumour size superior to 2cm (HR: 2,85, IC: 1,43-5,68) and macrometastatic lymph node status (HR: 3,11, IC: 1,47-6,58). Concerning overall survival, multivariate analysis demonstrated a significant impact of age less than 50 years (HR: 5,2, IC: 1,39-19,49), histological grade 3 (HR: 5,03, IC: 1,19-21,25), tumour size superior to 2cm (HR: 2,53, IC: 1,13-5,69). Analysis concerning macrometastatic lymph node status nearly reached significance (HR: 2,43, IC: 0,99-5,93). There was no detectable effect of chemotherapy regarding disease free survival (odds ratio [OR] 0,8, IC: 0,35-1,80) and overall survival (OR: 0,72, IC: 0,28-1,82). Disease free survival was similar between no axillary invasion (pN0) and isolated tumor cells (pNi+), or micrometastatic lymph nodes (pNmic). There were no difference neither between one or more than one macromatastatic lymph node. But disease free survival was statistically worse for pN1 compared to other lymph node status (pN0, pNi+ or pNmic). Factors associated with lymph node involvement after logistic regression was: age from 51 to 65 years (OR: 2,1, IC 1,45-3,04), age inferior to 50 years (OR 3,2, IC: 2,05-5,03), Tumour size superior to 2cm (OR 4,4, IC: 3,2-6,14), SBR grading 2 (OR 1,9, IC: 1,30-2,90) and SBR grade 3 (OR 3,5, IC: 1,61-7,75). CONCLUSION: The analysis of this series of 940 T1 and T2 lobular invasive breast carcinomas offers several information: factors associated with axillary lymph node involvement are age under 65 years, tumor size greater than 20mm, and a SBR grade 2 or 3. The same factors were significantly associated with the OS and DFS. The macrometastatic lymph node involvement has a significant impact on DFS and OS, which is not true for isolated cells and micrometastases, which seem to have the same prognosis as pN0.

Women who have undergone surgical treatment for breast cancer often benefit from a contralateral reduction mammaplasty (CRM) aimed at symmetrization of the contralateral breast unaffected by the initial cancer. In our 7-year multicentric study (12 centers) of 2718 patients, incidence of CRM cancers (CRMc) was 1.47% (n = 40) [95% CI 1.05%-2.00%]. The CRMc group had significantly more initial mammary cancers of invasive lobular carcinoma (ILC, 22.5% vs 12.0%) and ductal carcinoma in situ (DCIS, 35.0% vs 21.6%) types than the healthy CRM group (p = 0.017). 35.0% (n = 14) of patients had en bloc resection; 25.0% (n = 10) of surgical specimens were correctly oriented. En bloc resection and orientation of surgical specimens enable precise pinpointing of the CRMc. A salvage lumpectomy may be proposed as an option when margins are invaded. The histological distribution of the 40 CRMc (mean size 12.7 mm) was carcinoma in situ (CIS) 70%, ILC 12.5%, invasive ductal carcinoma (IDC) 12.5% and tubular carcinoma (TC) 5.0%.

BACKGROUND: A subgroup of T1N0M0 breast cancer (BC) carries a high potential of relapse, and thus may require adjuvant systemic therapy (AST). PATIENTS AND METHODS: Retrospective analysis of all patients with T1 BC, who underwent surgery from January 1999 to December 2009 at 13 French sites. AST was not standardized. RESULTS: Among 8100 women operated, 5423 had T1 tumors (708 T1a, 2208 T1b and 2508 T1c 11-15 mm). T1a differed significantly from T1b tumors with respect to several parameters (lower age, more frequent negative hormonal status and positive HER2 status, less frequent lymphovascular invasion), exhibiting a mix of favorable and poor prognosis factors. Overall survival was not different between T1a, b or c tumors but recurrence-free survival was significantly higher in T1b than in T1a tumors (P = 0.001). In multivariate analysis, tumor grade, hormone therapy and lymphovascular invasion were independent prognostic factors. CONCLUSION: Relatively poor outcome of patients with T1a tumors might be explained by a high frequency of risk factors in this subgroup (frequent negative hormone receptors and HER2 overexpression) and by a less frequent administration of AST (endocrine treatment and chemotherapy). Tumor size might not be the main determinant of prognosis in T1 BC.

BACKGROUND: Pure Tubular Carcinoma (PTC) of the breast is a rare histological subtype of invasive breast cancer characterized by a low rate of lymph node involvement. Currently there is no consensus on less surgical axillary node staging according to this histological subtype. METHODS: We performed a retrospective multi-institutional study. Inclusion criteria were PTC, sentinel lymph node detection (SLND) and conservative breast surgery. RESULTS: From January 1999 to December 2006, 234 patients were included in the study from 9 institutions. The median pathological tumor size was 9.59 (1-22) mm. SLN were successfully detected in 98% (229/234) of patients. Among the 234 patients, a macrometastasis was found in 6 cases (2.5%), micrometastasis in 15 cases (6.4%), and isolated cells in 2 cases (0.8%). In the case of patients with SLND macrometastasis, half of them had macrometastasis in the complementary axillary lymphadenectomy, and none in the case of SLN only micrometastasis or isolated cells. Of the 122 patients with a pathological tumor size <10 mm, none had sentinel node macrometastasis. According to a multivariate analysis, pathological tumor size (>10 mm) was the only parameter significatively linked to the risk of lymph node involvement (p = 0.007). CONCLUSION: In a large multi-institutional series with SLND, we have shown that the risk of axillary lymph node involvement in PTC is very low. In the case of PTC <10 mm, we suggest that surgical axillary evaluation, even with SLND, may not be warranted.

Inflammatory syndrome is one of the rare emergency breast situations. Its etiology is benign, infectious in most cases. The clinical examination is often self-evident and suggests the diagnosis. But alone it is insufficient, and diagnostic tests are necessary to guide therapy. As essential as it is, mammography's limitations reinforce the benefit of ultrasonography, which in all cases reveals an abscess and has greater sensitivity for detecting a malignant tumor. If the etiology is benign, clinical signs will disappear with medical treatment, with no need for further investigation. While it is legitimate to initiate a trial treatment, it must not delay oncologic management, because of the severity of inflammatory cancer.

BACKGROUND: Our objective was to assess the global cost of the sentinel lymph node detection [axillary sentinel lymph node detection (ASLND)] compared with standard axillary lymphadenectomy [axillary lymph node dissection (ALND)] for early breast cancer patients. PATIENTS AND METHODS: We conducted a prospective, multi-institutional, observational, cost comparative analysis. Cost calculations were realized with the micro-costing method from the diagnosis until 1 month after the last surgery. RESULTS: Eight hundred and thirty nine patients were included in the ASLND group and 146 in the ALND group. The cost generated for a patient with an ASLND, with one preoperative scintigraphy, a combined method for sentinel node detection, an intraoperative pathological analysis without lymphadenectomy, was lower than the cost generated for a patient with lymphadenectomy [ 2947 (σ = 580) versus 3331 (σ = 902); P = 0.0001]. CONCLUSION: ASLND, involving expensive techniques, was finally less expensive than ALND. The length of hospital stay was the cost driver of these procedures. The current observational study points the heterogeneous practices for this validated and largely diffused technique. Several technical choices have an impact on the cost of ASLND, as intraoperative analysis allowing to reduce rehospitalization rate for secondary lymphadenectomy or preoperative scintigraphy, suggesting possible savings on hospital resources.

OBJECTIVE: Breast cancer is the most frequent secondary tumor for women treated for Hodgkin's disease. It is important to study the risk factors associated to be able to adapt the monitoring of these women. PATIENTS AND METHODS: This is a retrospective study from Institut Bergonié, a comprehensive French Cancer Center, concerning the women treated for Hodgkin's disease and having developed a breast cancer. RESULTS: Among 328 women treated for Hodgkin's disease between January 1968 and December 1994, 20 patients developed 25 breast cancers. The average age of the patients during the irradiation was 24 years and the average period of occurrence of the cancer was 19 years. An irradiation of the chest wall and an under-diaphragmatic irradiation in doses of 40Gy are risk factors for the occurrence of breast cancer. A young age, less than 30, in the treatment of Hodgkin's disease tend to be significant. DISCUSSION AND CONCLUSION: This population of women with a high risk of breast cancer thus has to benefit from an appropriate monitoring program, which is what we suggest setting up in the Institut Bergonié.

BACKGROUND: Axillary lymph node clearance (ALNC) improves locoregional control and provides prognostic information for early breast cancer treatment, but effects on survival are controversial. This multicentre, randomized pragmatic equivalence trial compares outcomes for post-menopausal early invasive breast cancer patients after locoregional treatment with ALNC and adjuvant therapies to outcomes after locoregional treatment without ALNC and adjuvant therapies. METHODS: From 1995-2005, women aged ≥ 50 years with early breast cancer (tumor ≤ 10 mm) and clinically-negative axillary nodes were randomized to receive treatment with ALNC (Ax) or without (no-Ax). Adjuvant therapies were prescribed according to hormonal receptor status and individual histological results. The primary endpoint was overall survival (OS); secondary endpoints were event-free survival (EFS) and functional outcomes. The trial was terminated due to lack of equivalence and low accrual after first interim analyses. TRIAL REGISTRATION: NCT00210236. RESULTS: Of 625 patients, 297 no-Ax and 310 Ax patients were maintained for final per-protocol analyses. OS and EFS at five years were not equivalent (Ax vs. no-Ax: 98% vs. 94% and 96% vs. 90% respectively). Recurrence was higher for no-Ax, particularly in the first five years after surgery. Axillary nodes were positive for 14% Ax patients but only 2% no-Ax patients experienced axillary node recurrence. Functional impairments were greater after ALNC. CONCLUSION: Our results fail to demonstrate equivalence of outcomes when ALNC is omitted from post-menopausal early breast cancer patient treatment. However the low locoregional recurrence rates warrant further examination over a longer duration, in particular to consider whether these would impact on survival.

BACKGROUND: After breast conservative treatment (BCT), young age is a predictive factor for recurrence in patients with Ductal Carcinoma In Situ (DCIS) of the breast. The purpose of this study was to evaluate predictive factors for recurrence and outcomes in these younger women (under 40 years) treated for pure DCIS. METHODS: From 1974 to 2003, 207 cases were collected in 12 French Cancer Centers. Median age was 36.3 years and median follow-up 160 months. Seventy four (35.8%) underwent mastectomy, 67 (32.4%) lumpectomy alone and 66 (31.9%) lumpectomy plus radiotherapy. RESULTS: 37 recurrences occurred (17.8%): 14 (38%) were in situ and 23 (62%) invasive. After BCT, the overall rate of recurrence was 27% (33% in the lumpectomy plus radiotherapy group vs. 21% in the lumpectomy alone group). Comedocarcinoma subtype (p = 0.004), histological size more than 10 mm (p = 0.011), necrosis (p = 0.022) and positive margin status (p = 0.019) were statistically significant predictive factors for recurrence. The actuarial 15-year rates of local recurrence were 29%, 42% and 37% in the lumpectomy alone, lumpectomy and whole breast radiotherapy and lumpectomy + whole breast radiotherapy with additional boost groups respectively. After recurrence, the 10-year overall survival rate was 67.2%. CONCLUSION: High recurrence rates (mainly invasive) after BCT in young women with DCIS are confirmed. BCT in this subgroup of patients is possible if clear and large margins are obtained, tumor size is under 11 mm and necrosis- and/or comedocarcinoma-free.

BACKGROUND: To prospectively determine the feasibility of sentinel lymph node biopsy (SLNB) in preoperatively diagnosed multiple unilateral synchronous invasive breast cancers. PATIENTS AND METHODS: The Interest of Axillary Sentinel Lymph Node Biopsy in Multiple Invasive Breast Cancer (IGASSU) study was a prospective multi-institutional study with initial breast surgery, SLNB, and systematic axillary lymph node dissection (ALND). Patients eligible for the IGASSU study had an operable invasive multiple synchronous tumor (MST), defined as two or more physically separate invasive tumors in the same or different quadrant. RESULTS: From 1 March 2006 to 31 August 2007, 216 patients were prospectively included from 16 institutions. Of these patients, 211 were assessable. The SLNB-identified rate was 93.4% (197 of 211). The false-negative rate (FNR) was 13.6% (14 of 103) [95% confidence interval (CI) 7% to 20%], and the accuracy was 92.9% (183 of 197) (95% CI 89% to 96%). In a univariate analysis, tumor location (only external location versus other location) was the only clinicopathological factor influencing the FNR [22% (11%-33%) versus 7% (4%-10%)], even then median aggregate histological tumor size was smaller in external tumors [17 mm (range 12-80 mm) versus 34 mm (range 8-90 mm), P = 0.016]. CONCLUSION: With a FNR of 13.6%, we do not recommend SLNB as a routine procedure for MST, even for small tumor.

From March 2003 to April 2004, 77 physicians throughout France prospectively recruited 1289 ductal carcinoma in situ (DCIS) patients and collected data on diagnosis, patient and tumour characteristics, and treatments. Median age was 56 years (range, 30-84). Ductal carcinoma in situ was diagnosed by mammography in 87.6% of patients. Mastectomy, conservative surgery alone (CS) and CS with radiotherapy (CS+RT) were performed in 30.5, 7.8 and 61.7% of patients, respectively. Thus, 89% of patients treated by CS received adjuvant RT. Sentinel node biopsy (SNB) and axillary dissection (AD) were performed in 21.3 and 10.4% of patients, respectively. Hormone therapy was administered to 13.4% of the patients (80% tamoxifen). Median tumour size was 14.5 mm (6, 11 and 35 mm for CS, CS+RT and mastectomy, respectively, P<0.0001). Nuclear grade was high in 21% of patients, intermediate in 38.5% and low in 40.5%. Excision was considered complete in 92% (CS) and 88.3% (CS+RT) of patients. Oestrogen receptors were positive in 69.8% of assessed cases (31%). Treatment modalities varied widely according to region: mastectomy rate, 20-37%; adjuvant RT, 84-96%; hormone treatment, 6-34%. Our survey on current DCIS management in France has highlighted correlations between pathological features (tumour size, margin and grade) and treatment options, with several similar variations to those observed in recent UK and US studies.

PURPOSE: Predictive factors of non-sentinel lymph node (NSN) involvement at axillary lymph node dissection (ALND) have been studied in the case of sentinel node (SN) involvement, with validation of a nomogram. This nomogram is not accurate for SN micrometastasis. The purpose of our study was to determine a nomogram for predicting the likelihood of NSN involvement in breast cancer patients with a SN micrometastasis. METHODS: We collated 909 observations of SN micrometastases with additional ALND. Characteristics of the patients, tumours and SN were analysed. RESULTS: Involvement of SN was diagnosed 490 times (53.9%) with standard staining (HES) and 419 times solely on immunohistochemical analysis (IHC) (46.1%). NSN invasion was observed in 114 patients (12.5%), whereas 62.3% (71) had only one NSN involved and 37.7% (43) two or more NSN involved. In multivariate analysis, significant predictive factors were: tumour size (pT stage < or = 10 mm or >11 and < or = 20 or >20 mm [odds ratio (OR) 2.1 and 3.43], micrometastases detected by HES or IHC [OR 1.64], presence or absence of lymphovascular invasion (LVI) [OR 1.76], tumour histological type mixed or not [OR 2.64]. The rate and probability of NSN involvement with the model are given for 24 groups, with a representation by a nomogram. CONCLUSION: One group, corresponding to 10.1% of the patients, was associated with a risk of NSN involvement of less than 5%, and five groups, corresponding to 29.8% of the patients, were associated with a risk < or = 10%. Omission of ALND could be proposed with minimal risk for a low probability of NSN involvement.

Ductal carcinoma in situ of the breast (DCIS) is rare in younger women, accounting for about 4% of all cases of DCIS in France, and tends to be diagnosed by clinical findings or casually, after plastic surgery. After breast conserving treatment, young age ( less than 40) is a predictive factor of relapses in patients with DCIS. Age may serve as one more parameter that should be considered in the complex decision-making process necessary to create a treatment plan for a woman with DCIS. Breast conservative treatment (BCT) could be used if: margins are free and more than 10 mm; if DCIS size is less than 11 mm and DCIS is free of necrosis and comedocarcinoma. Mastectomy ought to be proposed in case of: multifocal DCIS, or DCIS size more than 30 mm; invaded margins after re-excision; radiotherapy contraindicated; small breasts and patient choice. Immediate breast reconstruction should be proposed for patients with all the poor predictive factors. In other cases, treatment procedure will be explained to the patient and the treatment will be chosen by the patient in consultation with the medical team (radiologist, surgeon, pathologist and oncologist). Radiotherapy with boost or hormonotherapy with tamoxifen should not be used routinely but may be proposed individually.

OBJECTIVES: To analyze the characteristics and to establish prognosis factors for 52 men suffering from breast cancer from 1980 to 2004. PATIENTS AND METHODS: Men treated for breast cancer (invasive or in situ). A retrospective study analyzed clinical and histological characteristics, and treatment procedures. The probability of survival or recurrence was calculated using the Kaplan-Meier method. Prognostic factors were studied using the Log Rank test. RESULTS: The mean age of our patients was 63.5 years old. In 73.1% of cases, subaerolar tumors were the initial symptoms, the average size was 30.31 mm. Among patients, 17 (32.7%) had T1, 19 (36.5%) T2, two (3.8%) T3 and 14 (26.9%) T4. The most represented histological type was the infiltrative ductal carcinoma (84.6%). The spread rate to axillary lymph nodes was 63.6%. The hormone dependency of these tumors was proven in 84.6% of cases. Overall survival rate were about 69% at five years and 32% at 10 years. The spread to lymph node and to derm, the clinical stage were significant factors influencing disease free survival. None of these factors had any significance regarding overall survival. DISCUSSION AND CONCLUSION: Male breast cancer is a rare disease (about 1% of breast cancer) with a poor prognosis (32% 10 years disease free survival). An early diagnosis and better knowledge of the disease would certainly lead to improvement of prognosis.

OBJECTIVES: In a retrospective study of bilateral Ductal Carcinoma In Situ (DCIS), cases were analysed to determine the relationship between the two events. MATERIAL AND METHODS: From 1971 to 2001, among 812 patients with DCIS in Bergonie Institute, 78 suffering from bilateral DCIS and only19 were treated entirely in our institute. It was either synchronous DCIS or asynchronous (before 6 months). We realised a comparative study between, clinical and pathological characteristics of each DCIS. RESULTS: In case of asynchronous DCIS, contra lateral DCIS occurred after a median 75-months period and until 22 years after the first event. We found at least for one histological subtype an agreement in 53% of cases. In 31% of cases, the grade was the same. For low plus intermediary grade versus high grade, the agreement was 53%. There was a subtype and grade agreement of 32% and a subtype or grade agreement in 63% of cases. CONCLUSION: Histological agreement between the two lesions indicated the possible existence of in situ bilateral disease in these women. The local relapse rate was 20% and all of them were invasive. The risk of relapse in controlateral breast is high and patient needs a long follow up even in case of mastectomy.

OBJECTIVE: To determine the reliability of pretherapeutic laparoscopic pelvic lymphadenectomy in cervical cancer as a function of lymph node recurrences according to initial lymph node status: 1) to establish the false negative rate by analyzing lymph node recurrence in patients N-, 2) to verify treatment adequacy in patients N+ by comparing the rate of node recurrence to initial node positivity. PATIENTS AND METHODS: Retrospective analysis of a prospectively registered patient database. One hundred and ninety patients treated by a combination of radiotherapy and surgery for cervical cancer stages 1b to 2b in 95% of cases had undergone, from March 1992 to June 2003, a previous laparoscopic pelvic lymphadenectomy. Median follow-up was 40 months (range: 3-126 months). RESULTS: Initial lymph node positivity (N+) was found in 79 patients (42%). Fourteen patients (7.4%) presented with lymph node recurrence, all of whom have died from disease. Lymph node recurrence was found in 4/111 patients N- (3.6%) and in 10/79 patients N+ (12.7%), of whom 8/10 occurred outside the radiation fields. CONCLUSION: With a very low false negative rate, accuracy of the laparoscopic pelvic lymphadenectomy in the determination of lymphatic spread in cervical cancer is confirmed. It can still be considered the gold standard despite recent developments (e.g. sentinel lymph node determination) to which they should be compared. Treatment adequacy in patients N+ is confirmed.
