Skin sparing mastectomy (SSM) and subcutaneous mastectomy (SCM) are recent techniques. They are always associated with immediate breast reconstruction (IBR). Their safety from an oncologic point of view and indications are of great concern. In early breast cancer, SSM and SCM are associated with the same risk of local recurrence as a modified radical mastectomy, when correctly indicated. This has been validated by numerous studies. In these non-randomised studies, overall survival cannot be evaluated. Such techniques can now be validated in the oncologic setting when correctly indicated and when decision-making is always concerted and multidisciplinary. Skin-sparing techniques are obviously associated with better cosmetic results than secondary reconstructions. Thus SSM with IBR are ideally indicated for ductal carcinoma in situ, pure infiltrating or mixed carcinomas requiring mastectomy without subsequent radiotherapy. The selection criterion of no postoperative radiotherapy allows the right candidates to be chosen for SSM. But often this criterion cannot be obtained preoperatively. In such cases, performing a two-step operation could be a good option. The interval between operations can be used by the patient to obtain more information and to make a mature decision regarding her choice of treatment. It seems essential to be able to offer every patient SSM with IBR which are validated standardised indications. Such is not the case everywhere in France today. The organisation of primary care through professional networks should provide us with an opportunity to fulfil these needs.

Background: Neoadjuvant chemotherapy (NACT) increases the likelihood that breast conservation therapy for breast cancer patients will be successful. There is no available nomogram to predict breast conservation after NACT. The aim of the current study was to develop and validate nomograms for predicting residual tumor size and probability of a patient becoming eligible for breast conservation surgery after NACT., Methods: A total of 1147 patients treated at M. D. Anderson Cancer Center (Houston, TX) and the Institut Gustave Roussy (Villejuif, France) who received anthracycline with or without paclitaxel NACT were included in the analysis. Clinicopathologic data from 1 series were used to construct logistic regression models for breast conservation and residual tumor size < 3 cm after NACT and were validated on an independent series., Results: The discrimination and the calibration of the nomogram for predicting the probability of residual tumor size < 3 cm after anthracycline-based NACT were good when applied to the validation set (concordance index = 0.79; U-index = 10(-3)). The discrimination of the nomogram for predicting eligibility for breast conservation therapy was also good (concordance index = 0.67). However, the calibration had to be adjusted to take into account global rates of breast conservation surgery. A second nomogram adapted to preoperative chemotherapy regimens containing paclitaxel was established. The concordance index of the nomogram for predicting breast conservation was 0.71 (P < 10(-6)) for the independent dataset and the calibration was also good. The confrontation of both nomograms showed that predictions were highly correlated (r = 0.97), suggesting that eligibility for breast conservation therapy was independent of the preoperative chemotherapy regimen used., Conclusions: Nomograms were developed for breast cancer patients who received NACT to predict residual tumor size and whether the patient would thus become eligible for breast conservation therapy. These tools may be useful when counseling patients about treatment options, and a web-based interface is now available to help guide patients and physicians in these decisions., ((c) 2006 American Cancer Society.)

Aim: This study aimed to evaluate the role of specimen radiography in predicting margin status for non-palpable breast malignancies., Methods: We retrospectively reviewed the clinical and pathological data together with specimen radiographs of 164 women with ductal carcinoma in situ, who were referred to our centre between January 1997 and December 2000. In all cases microcalcifications were discovered on mammography. Lesions were localized preoperatively using a guide-wire. Specimen radiography findings and clinicopathological data were correlated with pathological findings., Results: Findings comprised 122 pure ductal carcinomas in situ (74%) and 42 mixed carcinomas, both infiltrating and in situ (26%). On the specimen radiographs, the lesions were close (<1mm) to one edge of the lumpectomy in 34 (21%) cases. Histologically, there were 103 positive resection margins (<1mm, 63%) and only 61 negative margins (> or =1mm, 37%). On univariate analysis, factors associated with positive resection margins were found to be distance from microcalcifications to edge of lesion on specimen radiographs, and radiological multifocality. On multivariate analysis (logistic regression), a radiological margin <5mm and multifocality were the only risk factors for close histological margins. Radiological margins were not associated with surgical findings., Conclusion: Our results demonstrate that there is a correlation between specimen radiographs and histological results. The clinical relevance of this should be evaluated in a prospective study.

Purpose: To compare concomitant and sequential adjuvant chemoradiotherapy regimens in node-positive, operable breast cancer patients., Methods and Materials: This was a randomized, French, multicenter, phase III trial enrolling 638 eligible women with prior breast surgery and positive axillary dissection. Patients in Arm A received 500 mg/m2 5-fluorouracil, 12 mg/m2 mitoxantrone, and 500 mg/m2 cyclophosphamide, with concomitant radiotherapy (50 Gy +/- 10-20-Gy boost). Patients in Arm B received 500 mg/m2 5-fluorouracil, 60 mg/m2 epirubicin, and 500 mg/m2 cyclophosphamide, with subsequent radiotherapy. Chemotherapy was administered on Day 1 every 21 days for 4 cycles., Results: Median treatment durations were 64 and 126 days (Arms A and B, respectively), with no significant difference in overall or disease-free survival. Five-year locoregional relapse-free survival favored patients with conservative surgery (two thirds of the population), with less local and/or regional recurrence in Arm A than in Arm B (3% vs. 9%; p = 0.01). Multivariate analysis in this subgroup showed a 2.8-fold increased risk of locoregional recurrence with sequential chemoradiotherapy, independent of other prognostic factors (p = 0.027). Febrile neutropenia and Grade 3-4 leukopenia were significantly more frequent in Arm A. Subclinical left ventricular ejection fraction events at 1 year were more frequent with concomitant radiotherapy (p = 0.02)., Conclusions: Concomitant radiotherapy with adjuvant fluorouracil, mitoxantrone, and cyclophosphamide has significantly better locoregional control in node-positive breast cancer after conservative surgery and 50% shorter treatment, albeit with slightly more acute toxicity. With mitoxantrone no longer available for adjuvant breast cancer treatment, alternative concomitant chemoradiotherapy studies are needed.

Introduction: The aim of this study was to determine the efficacy of Doppler ultrasonography (US) with perfusion software and contrast agent injection (DUPC) during radiofrequency (RF) treatment of local recurrent breast cancer., Materials and Methods: Ten patients were included in this monocentric prospective phase II study. DUPC was performed for each patient the day before treatment and immediately after RF in the operating suite. RF ablation was followed by a total mastectomy. The results of DUPC were compared to the histologic analysis of the operative specimen., Results: Before RF, contrast uptake exceeded 70% in 5 lesions and was less than 50% in 5 lesions. Immediately after RF, no vascularization was detected with DUPC in 9 of the 10 lesions. Contrast uptake attaining 30% was depicted in the remaining lesion. At histologic analysis, complete tumour destruction was confirmed in 7 of the 10 operative specimens., Conclusion: In this study, DUPC is highly efficient and better adapted for the confirmation of tumour destruction in tumours that are hypervascularised before RF compared to hypovascularised lesions.

Purpose: To combine clinical variables associated with pathologic complete response (pCR) and distant metastasis-free survival (DMFS) after preoperative chemotherapy (PC) into a prediction nomogram., Patients and Methods: Data from 496 patients treated with anthracycline PC at the Institut Gustave Roussy were used to develop and calibrate a nomogram for pCR based on multivariate logistic regression. This nomogram was tested on two independent cohorts of patients treated at the M.D. Anderson Cancer Center. The first cohort (n = 337) received anthracycline; the second cohort (n = 237) received a combination of paclitaxel and anthracycline PC. A separate nomogram to predict DMFS was developed using Cox proportional hazards regression model., Results: The pCR nomogram based on clinical stage, estrogen receptor status, histologic grade, and number of preoperative chemotherapy cycles had good discrimination and calibration in the training and the anthracycline-treated validation sets (concordance indices, 0.77, 0.79). In the paclitaxel plus anthracycline group, when the predicted pCR rate was less than 14%, the observed rate was 7.5%; for a predicted rate of > or = 38%, the actual rate was 85%. For a predicted rate between 14% to 38%, the observed rates were 50% with weekly and 27% with 3-weekly paclitaxel. This indicates that patients with intermediate chemotherapy sensitivity benefit the most from the optimized schedule of paclitaxel. Patients unlikely to achieve pCR to anthracylines remain at low probability for pCR, even after inclusion of paclitaxel. The nomogram for DMFS had a concordance index of 0.72 in the validation set and outperformed other prediction tools (P = .02)., Conclusion: Our nomograms predict pCR accurately and can serve as a basis to integrate future molecular markers into a clinical prediction model.

Objective: Axillary padding without drainage appeared to be a valuable alternative technique to vacuum drainage. The technique employs local muscles or the axillary aponeurosis for padding. We report here the clinical evaluation of muscular padding without drainage. The analysis of these results prompted us to also do a literature search for other alternatives aimed at reducing morbidity due to vacuum drainage., Patients and Methods: Muscular padding was prospectively performed by 8 different surgeons on a total of 152 patients at the Centre Rene-Huguenin (Saint-Cloud, France). Follow-up has attained 3.5 years. A comparative assessment of pain was conducted in 30 patients operated on with vacuum drainage., Results: This technique is easy to learn and reproducible. It facilitates post-operative follow-up, always allowing discharge at the 2nd or 3rd post-operative day without any home nursing. The late sequels are not increased. In contrast, pain was twice more intense during the first post-operative weeks compared with vacuum drainage, and the seroma rate was also increased., Discussion and Conclusion: Despite good efficacy, this worsening of pain is a major obstacle to the routine use of muscular padding. A technical improvement has been published very recently where the axillary aponeurosis was used to pad the axilla. It seems to be equally efficient but less painful than muscular padding. This technique is under clinical evaluation and could appear as a valuable option to vacuum drainage. Other alternatives are discussed. Most studies lack a direct comparison with vacuum drainage and a satisfactory evaluation of quality of life is also omitted. New studies with quality of life scales are ongoing. They should allow us to choose options that take this aspect into account in the future.

Aim: This study assessed the effects of multiple therapeutic factors on quality of life (QOL) in the treatment of breast cancer., Methods: We surveyed 179 recurrence-free women with early breast cancer who had undergone a sentinel lymph node procedure, between January 1999 and June 2001. Age, tumour size, breast and axillary procedure, nodal status, chemotherapy, supra-clavicular fossa radiotherapy, and hormone therapy were tested as possible factors associated with poor QOL., Results: Information on QOL was obtained for 148 out of 179 patients. Age less than 55 years and chemotherapy were factors associated with impairment of physical well-being. Tumour size was associated with poor socio-familial well-being. Factors associated with altered arm subscale scores were age <55, axillary procedure, nodal status, chemotherapy and supra-clavicular fossa radiotherapy. Unexpectedly, sentinel lymph node (SLN) procedure delayed the onset of chemotherapy if the metastatic status of SLN was not diagnosed intra-operatively., Conclusion: Efforts are needed to improve the QOL of young patients. Axillary procedure affects only QOL related to arm morbidity.

Background: Randomized trials comparing neoadjuvant versus adjuvant chemotherapy show that primary chemotherapy allows more frequent breast-preserving surgery even though no survival advantage has been demonstrated. The aim of the current study was to determine the predicting factors and the survival impact of breast conservation in patients with large breast tumors treated with neoadjuvant chemotherapy., Methods: Between January 1987 and December 2001, 594 patients with invasive T2-3 breast carcinoma who were ineligible for breast-conserving surgery (the mean initial tumor diameter was 49 mm) were treated with 3 or 4 courses of an anthracycline-based primary chemotherapy, surgery, and radiotherapy. Various clinicopathologic factors were tested as possible predicting factors of breast-preserving surgery. Survival analyses were performed to determine the implications of breast-conserving surgery on outcome., Results: After primary chemotherapy, 287 (48%) patients were eligible for breast-conserving surgery and 307 patients underwent a mastectomy. Initial tumor diameter > 5 cm, low histologic grade, lobular histology, and multicentricity were independent predicting factors of breast conservation ineligibility in the multivariate analysis (logistic regression). In the univariate survival analysis, a failure of breast-preserving surgery was associated with a poor outcome. Local disease recurrence-free survival rates were similar in patients treated with lumpectomy and mastectomy., Conclusions: The results reported in the current study suggested that initial diameter, histologic type and grade, and multicentricity are potential prechemotherapy predicting factors of breast conservation. When carefully selected, patients treated with breast conservation had a risk of local disease recurrence similar to the risk of chest wall disease recurrence after mastectomy., (Copyright 2004 American Cancer Society.)

Electrochemotherapy is a new local treatment of the solid tumors that can be defined as the local potentiation, by means of permeabilizing electric pulses, of the antitumor activity of non-permeant (e.g. bleomycin) or low-permeant (e.g. cisplatin) anticancer drugs. The electric pulses are delivered locally on the solid tumors, after the intravenous or intralesional injection of the chemotherapy agent. In this review, the basis of the electrochemotherapy are recalled. Then, after summarizing clinical data, we present some results of the European project Cliniporator, as well as the new pulse generator, the Cliniporator, that incorporates new features resulting from this research project, and that is fully conceived for a clinical use. Finally, future perspectives are discussed.

Radiation therapy represents a very important part of breast conservative treatment. The classic schedule consists in delivering a total dose of 50 Gy in 25 fractions on 5 weeks, sometimes associated with a 10 to 16 Gy boost. For elderly women with difficulties to move or for younger women having professional activity or with young children in charge, a 5 to 6 weeks radiation therapy with long and frequent transportations is sometimes difficult to achieve. The aim of partial breast irradiation (PBI) is to prevent, in a short period (5 to 8 days) and less transportations, the risk of local recurrence into the tumor bed. Different techniques have been described, using either interstitial brachytherapy (low or high dose rate) or intra-operative radiation therapy (IORT photons or electrons) or external beam radiation therapy. Phase II PBI trials using interstitial brachytherapy showed a local control rate of 0 to 4% with a follow-up of 20 to 75 months. The rate of good/excellent cosmetic results is 67 to 100%. Results analysis of trials using very new PBI techniques (MammoSite), IORT) remains more difficult. If phase III randomized trials could confirm that PBI achieved, for selected patients, local controls equivalent to those obtain with whole breast irradiation, PBI could improve quality of life during radiation therapy, and maybe contribute to have a cost effective breast cancer conservative treatment.

Aims: To identify factors predicting metastatic involvement of non sentinel axillary lymph nodes in breast cancer patients who underwent sentinel lymph node (SLN) biopsy followed by complete axillary dissection only in case of metastatic sentinel lymph node., Methods: A prospective database including 165 breast cancer patients who underwent SLN biopsy without further complete axillary dissection in case of non-metastatic SLN was reviewed. Primary tumor size, pathologic grade, lymphatic invasion in the primary tumor, estrogen receptor status, tumor size in the SLN and number of metastatic SLNs were tested as possible predictors of metastatic involvement of non-SLN., Results: The sentinel lymph node detection rate was 97% (160/165 patients). The mean number of SLNs per patient was 1.8 (range: 1-5). Fifty patients (31.3%) had a metastatic axillary SLN: 10 of the 42 patients with T1a or T1b breast tumors and 40 of the 118 patients with T1c< or = 15mm tumors. Fifteen of the 50 patients with metastatic SLN had metastatic non-SLN. Primary tumor size, tumor size in the SLN, pathologic grade, estrogen receptor status and age were not significantly associated with metastatic involvement of non-SLN. Number of metastatic SLNs fell short of reaching statistical significance (P: NS). Lymphatic invasion in the primary tumor was the only factor significantly associated with the presence of tumor in the non SLN (P<0.01)., Conclusion: In our series, only lymphatic invasion in the primary tumor was correlated with metastases detection in the non-SLN. We could not identify a subset of patients without metastatic non-SLN in patients with metastatic SLN.

Improvements in the specificity of radiopharmaceutical compounds have been paralleled by an upsurge of interest in developing small detectors to assist surgeons in localizing tumour tissue during surgery. This study reports the main technical features and physical characteristics of a new hand-held gamma camera dedicated to accurate and real-time intra-operative imaging. First clinical experience is also reported. The POCI (Per-operative Compact Imager) camera consists of a head module composed of a high-resolution interchangeable lead collimator and a CsI(Na) crystal plate optically coupled to an intensified position-sensitive diode. The current prototype has a 40-mm diameter field of view, an outer diameter of 9.5 cm, a length of 9 cm and a weight of 1.2 kg. Overall detector imaging characteristics were evaluated by technetium-99m phantom measurements. Three patients with breast cancer previously scheduled to undergo sentinel lymph node detection were selected for the preliminary clinical experience. Preoperative images of the lymphatic basin obtained using the POCI camera were compared with conventional transcutaneous explorations using a non-imaging gamma probe. The full-width at half-maximum (FWHM) spatial resolution was investigated in both air and scattering medium; when the phantom was placed in contact with the collimator, the POCI camera exhibited a 3.2 mm FWHM. The corresponding sensitivity was 290 cps/MBq. The preliminary clinical results showed that POCI was able to predict the number and location of all SLNs. In one case, two deep radioactive nodes missed by the gamma probe were detected on the intra-operative images. This very initial experience demonstrates that the physical performance of the POCI camera is adequate for radio-guided surgery. These results are sufficiently encouraging to prompt further evaluation studies designed to determine the specific and optimal clinical role of intra-operative imaging devices.

Sentinel lymph node (SLN) biopsy is effective to assess axillary nodal status and avoiding axillary lymph node dissection (ALND) in patients with clinically node-negative early stage breast cancer. No standardization of the technique has yet been established. This review discusses the feasibility, the accuracy and the different techniques for this procedure. Although the SLN can be successfully identified by either the dye or gamma probe-guided method, its identification is facilitated when the two techniques are combined. To increase the sensitivity of the pathological examination of the SLN, it is necessary to make multiple step sections with hematoxylin and eosin staining immunohistochemistry on permanent sections. The intraoperative frozen sections and imprint cytology examinations of the SLN may be useful in determining its status, but further studies are needed to establish their performance. In clinical practice, routine ALND can be avoided for small tumours when the multidisciplinary team has an extensive experience of this technique. However, long-term regional control and survival have to be studied in prospective randomised trials, before SLN biopsy can replace routine ALND as the preferred staging method for women with localized breast cancer.

Context: The "Standards, Options and Recommendations" (SOR) project, started in 1993, is a collaboration between the Federation of french cancer centers (FNCLCC), the 20 french cancer centers, and specialists from french public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and the outcome of cancer patients. The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery., Objectives: To develop clinical practice guidelines for non metastatic breast cancer patients according to the definitions of the Standards, Options and Recommendations project., Methods: Data were identified by searching Medline, web sites, and using the personal reference lists of members of the expert groups. Once the guidelines were defined, the document was submitted for review to 148 independent reviewers., Results: This article presents the chapter radiotherapy resulting from the 2001 update of the version first published in 1996. The modified 2001 version of the standards, options and recommendations takes into account new information published. The main recommendations are: (1) Breast irradiation after conservative surgery significantly decrease the risk of local recurrence (level of evidence A) and the decrease in the risk of local recidive after chest wall irradiation is greater as the number of risk factors for local recurrence increases (level of evidence A). (2) After conservative surgery, a whole breast irradiation should be performed at a minimum dose of 50 Gy in 25 fractions (standard, level of evidence A). (3) A boost in the tumour bed should be performed in women under 50 years, even if the surgical margins are free (standard, level of evidence B). (4) Internal mammary chain irradiation is indicated for internal or central tumours in the absence of axillary lymph node involvement (expert agreement) and in the presence of lymph node involvement (standard, level of evidence B1). (5) Sub- and supra-claviculr lymph node irradiation is indicated in patients with axillary node involvement (standard, level of evidence B1).

Sentinel node (SN) biopsy in breast cancer is still in a crucial stage of evaluation. Many teams have obtained excellent results using this method, with a detection rate always higher than 90% and a false negative rate between 0 and 8%, in prospective series. The main question is to know if lymphadenectomy can now be avoided when the SN is negative. The answer will come from the results of the two ongoing trials comparing sentinel node biopsy to axillary lymphadenectomy. But their results will be available only in two or three years. However, many teams, as at Institute Gustave Roussy, are now applying the technique routinely, because of the excellent results obtained during their learning curve. But there are some methodological differences between teams, which can influence the detection and false negative rates. Thus, several methodological standards remain to be defined. This review enable us to clarify a certain number of questions. Today, SN biopsy can only be performed by trained teams, with prospective evaluation of their results or participation in phase III trials.

The main objective is the development of clinical practice guidelines to improve the quality of health care and outcome for cancer patients. The methodology is based on literature systematic review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery., Objectives: To develop clinical practice guidelines according to the definitions of Standards, Options and Recommendations for endocrine therapy in patients with non metastatic breast cancer., Methods: Data have been identified by literature search using Medline, Embase, Cancerlit and Cochrane databases - until july 1999 - and the personal reference lists of the expert group. Once the guidelines were defined, the document was submitted for review to 125 independent reviewers., Results: The main recommendations for the endocrine therapy of patients with non metastatic breast cancer are: 1) Endocrine therapy modalities depend on menopausal status or age of women: ovarian suppression for premenopausal women, antiestrogen drug therapy for postmenopausal women (standard). 2) Tamoxifen (20 mg/d - 5 years) is beneficial to women with positive estrogen receptor tumor (standard, level of evidence A). There is no indication of tamoxifen treatment for women with negative estrogen receptor tumor (standard, level of evidence A). 3) For postmenopausal women with positive estrogen receptor tumor, tamoxifen is the standard adjuvant treatment (level of evidence A). For postmenopausal women with negative estrogen receptor, adjuvant chemotherapy has to be considered (option, level of evidence A). No adjuvant treatment has to be considered for women with poor health condition (option). 4) For premenopausal women with estrogen receptor tumor, results of clinical trials of chemotherapy versus endocrine therapy, suggest a benefit for endocrine therapy. However, there is no sufficient evidence to consider endocrine therapy alone as a standard adjuvant treatment. 5) For premenopausal women, chemotherapy + ovarian suppression or chemotherapy + tamoxifen are not better than chemotherapy alone (level of evidence A). 6) For postmenopausal women, administration of chemotherapy plus adjuvant tamoxifen versus the same tamoxifen alone, is of additional benefit in reducing recurrences but not in prolonging overall survival (standard, level of evidence A). 7) Balance of known benefits (delay to recurrence and death) and risks (side-effects of therapy) for adjuvant chemoendocrine therapy has to be taken into consideration before decision making. Chemoendocrine therapy can be indicated for women at high risk of developing metastatic disease (recommendation, experts agreement).

The methodology is based on literature systematic review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery., Objectives: To develop clinical practice guidelines according to the definitions of Standards, Options and Recommendations for the management of patients with cutaneous melanoma., Methods: Data have been identified by literature search using Medline - until December 1998 - and the personal reference lists of the expert group. Once the guidelines were defined, the document was submitted for review to national and international independent reviewers and to the medical committees of the 20 French Cancer Centres., Results: The main recommendations for the management of cutaneous melanoma (CM) are: 1) The primary prevention of melanoma is based on a reduction in exposure to ultraviolet rays (solar or artificial). 2) The diagnosis of CM requires the surgical removal and histological examination of the lesion (standard). 3) The pathological report must include the diagnosis of primary malignant melanoma, the maximum thickness of the tumour in millimeters (Breslow), the clearance of surgical margins, the level of invasion (Clark), the presence and extension of regression and the presence of any ulceration (standard). 4) The standard treatment of a primary melanoma without lymph node involvement is based on surgery that must ensure adequate margins depending on the thickness of the tumour (standard, level of evidence B). 5) After surgery of a stage I melanoma, there is no indication for additional treatment outside a prospective therapeutic study (standard, level of evidence B, French Consensus Conference). 6) For a local recurrence without node involvement, in the absence of other metastases, surgical excision is the standard treatment. 7) In the case of metastatic regional lymph nodes, a complete regional lymphadenectomy is required. There is no indication for additional treatment outside a prospective therapeutic study (standard, level of evidence B). The inclusion of these patients in controlled studies of immunotherapy is recommended. 8) There is no standard therapeutic strategy for metastatic melanoma. Conventional palliative treatment is chemotherapy with dacarbazine (level of evidence B). 9) Follow-up is based on physical examination (standard). Patient information must encourage self-surveillance. Clinical surveillance and self-detection are indicated in all cases throughout life (standard).

Study Aim: Breast cancer is the most frequent type of cancer in women, increasing in frequency with the elderly. In Europe, a third of new breast cancers occur in women over 70 years of age. The aim of this retrospective study was to analyse the tumoural lesions and therapeutic results in a female population over 70, treated in the same medical centre over a 15-year period., Patients and Methods: From 1978 to 1992, 1,143 female patients aged 70 or over were treated for a unilateral breast cancer without metastases and followed-up during a mean 6-year period. The initial treatment was surgical in 1,012 patients: radical mastectomy in 95% of the cases with axillary node dissection in 97.6%. Adjuvant radiotherapy was performed in 289 patients and adjuvant treatment with Tamoxifen in 411 patients. The results were compared with those obtained in 2,947 patients aged 50 to 69, treated during the same period in the same medical centre., Results: The 5-year survival rate in women 70 and over was 80% vs 85.5% in women aged 50 to 69 (P < 0.000001). The same rate of loco-regional recurrences and metastases occurred in both populations. In the patients who initially underwent surgery, after multivariate analysis according to the Cox model, the prognosis factors (similar to those observed in the group of younger women) were: the number of involved nodes (P = 0.000001), the clinical size of the tumour (P = 0.00001), the histological grade (P = 0.01), and the estrogen receptors (P = 0.02)., Conclusions: In this series, the treatment was focused on surgery complemented with adjuvant radiotherapy according to node invasion and adjuvant hormonotherapy according mostly to hormonal receptors. However, the complete treatment could not be applied to all cases: only 50% of patients with node involvement were irradiated. The 5-year survival rate lower than that of younger patients may be attributed to incomplete adjuvant treatment. Specific controlled trials taking into account quality of life had to be undertaken in elderly patients in order to adjust the treatment in relation with the patients' age and physiological condition.

Purpose: To assess contrast material-enhanced computed tomography (CT) of breast for diagnosing local recurrence after conservative therapy., Materials and Methods: In 111 patients, 118 lesions were evaluated with unenhanced and enhanced CT. Criterion for cancer recurrence was detection of a lesion with an enhancement of 45 HU or more., Results: One group comprised 52 lesions with pathologic diagnoses, obtained within 1 month of CT, of malignancy in 43 and benignancy in nine. Scans were positive in 40 of 43 recurrences and negative in six of nine benign lesions. Seventeen recurrent lesions were nonpalpable, and contrast-enhanced CT results were true-positive in 15 of these. A second group comprised 66 lesions with a mean follow-up of the treated breast of 28 months after CT. In 56 lesions, the scans were negative, with no recurrence in 55; local recurrence was proved with a 14-month delayed surgical biopsy in one. In 10 lesions, scans were positive, with a delayed diagnosis of recurrence 5 and 6 months after CT in two and no evidence of recurrence in eight (false-positive results). The sensitivity of breast CT for both groups was 91% (42 of 46 lesions) with a specificity of 85% (61 of 72 lesions)., Conclusion: Contrast-enhanced CT is sensitive in the diagnosis of local recurrence of breast cancer, even in nonpalpable lesions, and may be a useful tool in patients with equivocal clinical and/or mammographic findings during follow-up after conservative therapy.

A total of 196 records of colonoscopic surgical complications were reviewed during a 12-year period. Perforation (183 patients) and haemorrhage (11) were the two main complications. Diagnosis of perforation was delayed in 58 per cent of patients. The sigmoid colon was the site of perforation in 72 per cent with evidence of peritoneal contamination in 59 per cent. Postoperative mortality rate of perforation was 12 per cent and was significantly related to a past history of medical disease and size of perforation. Postoperative morbidity rate was 43 per cent. There were two deaths after colostomy closure. The overall mortality rate of colonoscopic perforation requiring an emergency surgical procedure reached 14 per cent. Haemorrhage always occurred after endoscopic polypectomy; the postoperative course was uneventful in these patients.

We studied the clinical factors of metastatic risk of breast cancer in 5609 consecutive cases of unilateral invasive breast cancer, wholly treated and followed at René-Huguenin Center from 1962 to 1988, and without any other cancer (even a controlateral breast cancer). All these patients were protocolary treated; these protocols, especially medical treatments (chimio and hormonotherapy), being modified along with years. At 20 years, the global metastasis free survival was 56%. Clinical size, existence of inflammatory signs, UICC clinical stage, clinical nodal status were highly significant in the Cox multivariate analysis (P < 0.000001). Age (P < 0.0008) and adherence to skin or underlying parietal (P < 0.007) were also but less significant. On the other hand, location of the tumor, time between first signs and diagnosis were not predictive. The women under 35 years had more metastatic locations during their evolution (P < 0.05) and maybe more visceral metastasis (NS).

In 1994, the treatment of ductal carcinoma in situ of the breast remains a controversial subject. There are two reasons for this: first, there are many possible treatments and secondly, there is still much discussion on choice criteria. Possible options are: Total mastectomy which or without axillary dissection. Tumorectomy followed by locoregional radiation therapy. Simple tumorectomy. Tamoxifen can be added to each of these options. The choice criteria are based on our knowledge of the complex natural history of these cancers. In this area some of the current concepts must be seriously revised. All of the former concepts were based on lesions observed at the time of their elaboration. These were voluminous tumours, diagnosed late with no prior conservative treatment. However, today, the lesions observed are quite different. We see "young" lesions which are naturally much smaller. It would appear that the natural history of small sized in situ ductal carcinoma of the breast is quite different from that of large sized tumours. The lesions seen today are less multifocal and less multicentric in nature than is generally thought. The progression of a small tumour is essentially segmentary. Likewise, the risk of occult micro-invasion is certainly less than previously thought. Even if the risk of micro-invasion still does exist, the risk of axillary lymph node invasion (resulting from an unknown infiltrating zone of tumoural tissue) is much lower. Finally the dogma of radioresistance, which was not based on any carefully conducted radiobiological study, has lost its substance since recent results on radiosurgery combinations have been published.(ABSTRACT TRUNCATED AT 250 WORDS)

There has been growing interest in intraductal carcinomas of the breast (DCIS) over the last ten years mainly because of their increasing frequency and their difficult diagnosis. Their natural history is often surprising. For the time being, it is impossible to establish which proportion of DCIS might turn into an infiltrating carcinoma, and which factors are predictive for such a risk. These uncertainties are responsible for many controversies about their treatment. Based on a critical review of the latest publications, this paper deals with the possibilities of conservative treatment, challenging the remarkable results of total mastectomy (nearly 100% survival at 10 years). The risk of conservative treatment depends on the frequency of local recurrence, and on the potential vital risk of such recurrences, knowing that half of these recurrences will develop in an invasive, and no longer in situ, pattern. Randomized trials are being conducted on this question; they will not give an answer before the year 2000. In the mean time, conservative treatment seems to be reasonable for small low grade histologic lesions widely excised by surgery, and with rigorous possibilities of follow-up. The operation is followed by external irradiation. In case of recurrence, mastectomy has to be. It is not impossible that, performed under these conditions, a slight increase in mortality might follow such a strategy, thus heavily balancing the benefits of conserving the breast. Besides, surgical excision alone should only be performed as part of randomized trials, or for infra-centimetric lesions discovered by histology after resection of supposed benign lesions.

323 reconstructions of the breast were carried out at the Gustave-Roussy Institute and were analysed in order to assess the aesthetic results and the sequelae of these reconstruction operations. The majority of the patients were operated on between 1984 and 1989 with a median follow-up of 3.5 years (1 to 9 years). Three types of reconstruction were carried out: simple prosthesis behind the muscle (P, 69% of this population), latissimus dorsi flap (G.D., 11%), or transverse rectus abdominis flap (TRAM, 20%). These reconstructions were either carried out immediately (RMI, 23.5%) or later (RMD, 76.5%). The unanimous enthusiasm of the patients for reconstruction was the greatest encouragement for us to continue in this way. From the aesthetic point of view the transverse rectus abdominis flap (TRAM) proved to be superior to the others. Scar and functional sequelae of the latissimus dorsi flap (GD) were by no means nil in this series (table 9) in contrast with other studies that have been carried out. All the same the majority of these sequelae were larger scars. The functional poor sequelae were minor. TRAM sequelae were less frequent and usually mainly in the abdominal wall. A more accurate technique should lower the incidence. As far as the timing of surgery is concerned, immediate reconstruction did not alter the quality of results which were better (but not significantly statistically). This has already been published. On the other hand patients were more satisfied with RMD (p less than 10(-4)). The analysis of this unexpected result show the great significance of psychological factors in interpreting these results.(ABSTRACT TRUNCATED AT 250 WORDS)

Elastofibroma is a rare tumor mainly found under the scapula. Based on a recent study of five cases, we would like to stress the importance of making the diagnosis of elastofibroma, as this lesion simply consists of dysplasia of the elastic fibres and is not malignant as could be suggested by clinical examination.

This study involved 17 cloacogenic cancers classified on the Morson and Jass histological scale and on the TNM clinical classification as T1 (4), T2 (3), T3 (3) and T4 (7) and including 5 N+ cases at the time of diagnosis. Treatment combined radiotherapy and surgery and the overall actuarial survival was 45% after 5 years. These results confirm that the response to treatment of cloacogenic cancers is similar to that of epidermoid cancers, notably with regard to the response to radiotherapy, and that the prognosis depends above all on the initial extent of the cancer. In contrast, cancers showing little or no differentiation (small cell cloacogenic cancers) are distinguished from other duct cancers by their explosive metastatic potential.
