RESUMEN

INTRODUCTION: Cytoreductive surgery of locally advanced ovarian cancer has evolved in the last few years from surgery to remove macroscopic residual disease (<1cm; R2b) to macroscopic complete cytoreductive surgery with no gross residual disease (R1). The aim of this study was to evaluate the impact of the adoption of a maximalist surgical approach on postoperative complications, disease recurrence and survival. MATERIALS AND METHODS: This was a retrospective study using prospectively collected data on patients who received either conservative approach (CA) or radical approach (RA) surgical treatment for primary ovarian cancer stage IIIc/IVa/IVb between June 2006 and June 2013. RESULTS: Data for 114 patients were included, 33 patients in the CA group and 68 patients in the RA group were consequently analysed. In the RA group, operative time was longer, in relation to more complex surgical procedures; with more blood losses and a higher rate of compete macroscopic resection. Totally, 77% of the patients had postoperative complications, with more grade I/II complications in the RA group but the same rates of grade III/IV complications in the both groups (P=0.14). For all patient study population, the overall and disease-free survivals were improved in case of no macroscopic residual disease. Overall survival was improved in the RA group (P=0.05), with no difference in terms of disease-free survival (P=0.29) CONCLUSION: A radical approach in advanced ovarian cancer allows a higher rate of complete cytoreductive surgery impacting overall survival. However, a non-significant trend for increased mild complications (grade I/II) rate is observed in this group.

RESUMEN

In Belgium, breast cancer is the most frequent women's cancer accounting for to 35.3 % of the cases. In 2013, 10,778 newly diagnosed breast cancers have been reported in Belgium. Breast cancer has a relatively good prognosis with a 5 year overall survival of 88 %. Survival will be different regarding the subtype and stage at diagnosis. The review of the literature and the guidelines from ESMO and ASCO regarding the follow-up of patients with early breast cancer will be used as references. International guidelines recommend clinical visits (frequencies depending of the subtypes of breast cancer) with an annual mammography associated with an echography. MRI Imaging should be performed in " at risk " patients. A more extensive exploration should be proceede when a relapse is suspected during follow up. Indeed, studies have shown that intensive follow- up with several additional exams detect more recurrences without any impact on overall survival and lead to anxiety. The follow-up of patients treated for breast cancer has several objectives : - Detect a local recurrence or a second tumor ; - Diagnosis of a distant relapse ; - Detect side effects of treatment ; - Psycho-social impact of the disease and improve the quality of life.


En Belgique, le cancer du sein est le cancer le plus fréquent chez la femme (35,3 % des cas). En 2013, 10.778 nouveaux cancers du sein ont été répertoriés. Son pronostic est relativement bon, avec des taux de survie à cinq ans de 88 %. Il sera différent en fonction du type de cancer du sein et de son stade. La revue de la littérature et les recommandations actuelles de l'ESMO (European Society of Medical Oncology) et de l'ASCO (American Society of Clinical Oncology) concernant le suivi des patientes traitées pour un cancer du sein, seront prises comme références. Les recommandations internationales se limitent à des consultations cliniques (dont la fréquence peut varier selon les types de cancer du sein) associées à une mammographie de même qu'à une échographie mammaire annuelle tandis qu'une résonance magnétique nucléaire sera également réalisée chez les patientes à risque. Un bilan est à réaliser dans le cadre du suivi uniquement si une rechute est suspectée. En effet, de nombreuses études ont montré que la surveillance dite intensive est responsable certes de la découverte d'un plus grand nombre de rechutes, mais également d'une angoisse accrue chez les patientes et n'a pas d'impact favorable sur la survie sans progression ou sur la survie globale. La surveillance des patientes ayant été traitées pour un cancer du sein vise plusieurs objectifs : - Rechercher une récidive locale ou une deuxième tumeur ; - Diagnostiquer une récidive à distance ; - Détecter les possibles complications secondaires aux traitements adjuvants administrés ; - Évaluer le retentissement psycho-social de la maladie et améliorer la qualité de vie des patientes.

RESUMEN

Objectives. The aim of this prospective phase II study is to evaluate the treatment of early-stage breast cancer (T1 N0) with intraoperative electron radiation therapy (IOERT) in terms of local control, early complications, and cosmesis. Patients and Methods. From February 2010 to February 2012, 200 patients underwent partial IOERT of the breast. Inclusion criteria were unifocal invasive ductal carcinoma, age ≥40 years, histological tumour size ≤20 mm, and no lymph node involvement. A 21 Gy dose was prescribed over the 90% isodose line in the tumour bed. Median follow-up is 23.3 months (7-37). Results. Acute toxicity was not frequent (Grade 1: 4.5%, Grade 2: 1%). The cosmetic result was considered to be very good or good in 92.5%. One ipsi lateral out-quadrant recurrence at 18 months was observed. The crude and actuarial local recurrence rates after median follow-up were 0.5% and 0.9%, respectively. Conclusion. The preoperative diagnostic work-up must be comprehensive and the selection process must be rigorous for this therapeutic approach reserved for small ductal unifocal cancers. After a 23.3-month median follow-up time, the clinical results of IOERT for selected patients are encouraging for the locoregional recurrence and the toxicity rates. The satisfaction of our patients in terms of quality of life was extremely high.

RESUMEN

STUDY QUESTION: Do the benefits of ovarian tissue cryopreservation outweigh the risks for patients seeking to preserve fertility before gonadotoxic treatment in various indications? SUMMARY ANSWER: In >90% of the patients undergoing cryopreservation of ovarian tissue, oncological treatment was associated with a reduced ovarian reserve and in 30% of patients, premature ovarian failure (POF) occurred within 5 years. WHAT IS KNOWN ALREADY: Ovarian tissue cryopreservation is an effective fertility preservation option, especially for pre-pubertal patients and patients who have a short time between diagnosis of a disease and gonadotoxic treatment. STUDY DESIGN, SETTING, DURATION: This study retrospectively analysed ovarian function and fertility recovery rates, as well as ovarian tissue characteristics, of patients who underwent ovarian tissue cryopreservation at Erasme Hospital between 1999 and 2011. PARTICIPANTS/MATERIALS, SETTINGS, METHODS: A total of 225 patients referred from 15 Belgian oncological units underwent cryopreservation of ovarian tissue before gonadotoxic therapy for malignant or benign diseases. There were 28 patients (12.4%) who died during follow-up due to recurrence of disease. One severe adverse event occurred during anaesthesia for ovarian tissue collection, leading to the death of the patient. Ovarian function and fertility outcomes were available for 114 patients including 13 girls who were pre-pubertal at the time of the procedure. Eight patients had undergone ovarian tissue transplantation in order to restore their fertility after remission of the disease. MAIN RESULTS AND THE ROLE OF CHANCE: Breast cancer and haematological disease were the most frequent indications for ovarian tissue cryopreservation. Overall, 90% of post-pubertal patients were diagnosed with poor ovarian reserve (AMH < 0.5 ng/ml) after a mean of 50 months of follow-up (11-125 months), including 30% with POF (FSH > 40 IU/ml). Breast cancer patients had a lower rate of POF than did post-pubertal patients with haematological diseases (11 versus 34.5%, respectively), despite the older age (mean 31 versus 23.5 years old, respectively) of the breast cancer patients. Ovarian function returned in 71 post-pubertal patients without the need for grafts of cryopreserved tissue. Spontaneous pregnancies were reported for 33 of them, leading to 34 live births. Among the 13 pre-pubertal patients who reached pubertal age during the follow-up, 10 had POF. Eight patients received cryopreserved ovarian grafts to reverse POF and three of them have already become pregnant. LIMITATIONS, REASONS FOR CAUTION: This study is a retrospective analysis. The cohort was not compared with a control group of patients who did not undergo the procedure. WIDER IMPLICATIONS OF THE FINDINGS: After careful evaluation of the surgical risks, ovarian tissue cryopreservation can be proposed as an efficient option to preserve the fertility of children and young adults facing gonadotoxic therapies. However, alternative procedures such as oocyte or embryo cryopreservation should be considered as first options especially for older patients or if there is high risk of neoplastic cells within the ovaries. STUDY FUNDING/COMPETING INTEREST: This study was supported by the Télévie, FNRS-FRSM and Fondation Belge contre le cancer. There are no competing interests to report.

RESUMEN

BACKGROUND: The prognostic value of histologic grade (HG) in invasive lobular carcinoma (ILC) remains uncertain, and most ILC tumors are graded as HG2. Genomic grade (GG) is a 97-gene signature that improves the prognostic value of HG. This study evaluates whether GG may overcome the limitations of HG in ILC. METHODS: Gene expression data were generated from frozen tumor samples, and GG calculated according to the expression of 97 genes. The prognostic value of GG was assessed in a stratified Cox regression model for invasive disease-free survival (IDFS) and overall survival (OS). RESULTS: A total of 166 patients were classified by GG. HG classified 33 (20%) tumors as HG1, 120 (73%) as HG2 and 12 (7%) as HG3. GG classified 106 (64%) tumors as GG low (GG1), 29 (17%) as GG high (GG3) and 31 (19%) as equivocal (cases not classified as GG1 or GG3). The median follow-up time was 6.5 years. In multivariate analyses, GG was associated with IDFS [HR(GG3 vs GG1) 5.6 (2.1-15.3); P < 0.001] and OS [HR(GG3 vs GG1) 7.2, 95% CI (1.6-32.2); P = 0.01]. CONCLUSIONS: GG outperformed HG in ILC and added prognostic value to classic clinicopathologic variables, including nodal status.

RESUMEN

A RT-PCR assay (GeneSearch™, Veridex, LLC), FDA approved and CE marked to detect metastases > 0.2 mm in sentinel lymph nodes (SLNs) is used intra-operatively for the management of patients with breast cancer. The assay provides qualitative results by applying cut-off values to cycle times (Ct) for mammaglobin (MG) and cytokeratin-19 (CK19) genes. Aims of this study were to evaluate the performance of the quantitative Ct values to estimate the size of nodal metastases and the risk of additional disease in non-SLNs. SLNs from 367 patients were clinically processed using both BLN assay and post-operative histology. Complementary axillary lymph node dissection (ALND) was performed concurrently in case of BLN assay positivity or tumour size > 2 cm. BLN positivity was reported in 19.6% of the patients for a sensitivity of 89%. BLN specificity (94.5%) and negative predictive value (97.5%) clearly demonstrated its reliability to guide ALND decision. All, except one, residual axillary metastases were found in BLN-positive patients. Considering the 78 patients with SLN positivity or discordant status according to both criteria, the metastases histological size was significantly correlated to the expression level of MG (ρ = 0.62) and CK19 (ρ = 0.64) genes (P < 10E-6). Moreover, ALND status positivity was significantly associated to Ct value of MG (z = 2.4; P = 0.018) and CK19 (z = 3.2; P = 0.001). The high intra-operative quality performance of the BLN assay minimizes the need for second surgeries for ALND. Results from this investigational study suggest that markers Ct value may provide, intra-operatively, valuable metastases size data and a risk prediction of additional disease in non-SLNs.

RESUMEN

BACKGROUND: In breast cancer patients, the status of the sentinel lymph nodes (SLNs) has been shown to accurately reflect the presence of metastases in the axillary lymph nodes (ALNs). Intra-operative SLN evaluation by frozen section histology may miss positive cases, leading to a second surgery for complete ALN dissection. Permanent section histology itself has tissue sampling limitations and is partially dependent on pathologist expertise. METHODS: A prospective study (N=78) was conducted in our institution to validate a new intra-operative molecular assay, the GeneSearch breast lymph node (BLN) assay. This assay quantifies the expression of mammaglobin and cytokeratin-19 genes using quantitative RT-PCR technology to determine SLN status. Fresh SLN sections (2 mm thick) were analyzed alternatively by BLN assay or post-operative histology (haematoxylin-eosin and immunohistochemistry). The subject was considered positive when histology revealed a focus >0.2 mm. RESULTS: BLN assay results corroborated with histologic results in 75 out of 78 patients for an overall agreement of 96%, a sensitivity of 92%, and a specificity of 97%. The positive and negative predictive values of the BLN assay were of 86% (12/14) and 98% (63/64), respectively. Interestingly, a statistically significant correlation was observed between the metastases' histologic size and both assay markers' expression levels as represented by cycle time to positivity (rho > or = 0.71, all p<0.0001). CONCLUSIONS: The performance of the BLN assay in identifying nodal metastases >0.2 mm was similar to that of permanent section histology, with the added advantages of an objective and rapid output that could be used for intra-operative decision to remove additional ALN.

RESUMEN

INTRODUCTION: To investigate the influence of ageing on the incidence of breast cancer (BC) molecular subtypes, patient age at diagnosis was correlated with bio-pathological data collected retrospectively from 2723 consecutive patients diagnosed/treated at our Institute between 2000 and 2003. METHODS: According to their bio-characteristics, 61% of the samples could be assigned to a molecular subtype: the "HER-2+", the "ER & HER2 negative" or one of the two "luminal-like" subtypes divided according to their histological grade ("A" [HER-2-/ER+/grade 1-2] and "B" [HER-2-/ER+/grade 3]). RESULTS AND CONCLUSION: Age is highly influencing the incidence of BC molecular subtypes. Patients younger than 40 develop a statistically higher rate of high grade proliferating "HER-2" (27%) and "ER & HER2 negative" (31%) BC whereas patients older than 50 develop mostly less aggressive hormone-dependant "luminal-A" BC (>67%). Nevertheless, a significant proportion of patients older than 70 develop "luminal-B" (19%) tumours associated with high proliferation, high grade, large size and nodal invasion.

RESUMEN

AIMS: The objective of this study was to assess the value of superficial (intradermal) and paratumoral (above the tumor) (ID) injection of labeled colloids for imaging sentinel lymph nodes (SLN) as a rescue technique in breast cancer patients for whom deep (intraparenchymatous) and peritumoral (around the tumor) (IP) injections had failed. METHODS: We assessed data from 2 groups of women: 469 women for whom IP injections successfully visualized a SLN (IP-only) and 52 women for whom IP injections were unsuccessful and ID injection was performed (IP0-ID). Patient characteristics and SLN results were compared. RESULTS: Most characteristics of the two patients series were similar. However, IP0-ID patients were on average 10years older than the IP-only patients and had more grade-III tumors. The false negative rate (FNR) for the IP0-ID patients (9/25, 23.8%) was significantly higher than for the IP-only patients (12/240, 5%; p<0.01) and for a subgroup of IP-only patients older than 50 years (8/159, 5%; p=0.009). Four of five false negatives in the IP0-ID group involved a tumor in the outer quadrants. The FNR for cases with external tumors was 33% for the IP0-ID patients, a percentage significantly higher than the corresponding values for the IP-only patients (5.8%) and for the IP-only patients older than 50 years (5.7%). CONCLUSION: In patients with unsuccessful deep IP injections, superficial ID injections lead to a high percentage of false negative SLN conclusions, merely when tumours were located in the outer quadrants. Thus, it is recommended that patients with unsuccessful intra-parenchymatous and peritumoral injections of radiocolloids for tumors in outer quadrants undergo complete axillary dissection.

RESUMEN

OBJECTIVES: Concomitant chemoradiation is the "new gold standard" for dealing with locally advanced cervical carcinoma, but what about surgery? We don't know yet to what extent surgery is necessary and how radical it must be when it is performed. In this study, we present the analysis of the results obtained in patients treated by concomitant chemoradiation followed by radical surgery. MATERIALS AND METHODS: Twenty-two patients, median age 49 years, with I(b) - III(a) cervical tumors were enrolled to be treated by concomitant chemoradiation followed by radical surgery. The chemoradiation protocol included external radiotherapy to the pelvis: 45 Gy; Cisplatin 40 mg/m(2) in continuous intravenous infusion once a week (5 weeks) followed by brachytherapy one week later. Surgery was performed 4 to 6 weeks later and consisted in radical hysterectomy with pelvic lymphadenectomy. RESULTS: 20/22 patients underwent surgery after chemoradiation because of a diagnosis of lung metastases in one and presence of a nonresectable metastasis for the other. A complete pathological response was demonstrated in 12/20 patients (60%), a microscopic residual tumor in 7 patients (35%), and residual disease <1cm in 1 patient (5%). CONCLUSION: This study showed a particularly high rate of pathologic responses (T(0)+T(mic): 95%) and of local control. We don't know yet if surgery is a real necessity or if it could be less extended after concomitant chemoradiation.

RESUMEN

The aim of the study is to see if Bone Scan (BS) - when performed the day before the operation-interferes with the results of the Sentinel Lymph Node (SLN) technique using radiocolloids (their pre-operative imaging and their peroperative research). Therefore, the data of 393 patients who had one selective lymphadenectomy of the SLN(s) followed by the complete axillary node (AxN) clearance for Breast Cancer and among whom 309 patients had one BS the day before the operation (and just before the injection-s for the SLN) and 84 did not, were analysed and compared. The two series presented the same characteristics with regard to: age, clinical staging of the tumour, kind of injection-s performed (intradermic and paratumoural and/or intraparenchymal and peritumoral), pathological size of the tumour, percentage of cases with no AxN invasion, total number of AxN removed by the surgeons. The percentages of no axillary SLN visualisation, the mean numbers of axillary SLN visualised on pre-operative lymphoscintigram as well as of SLN removed by the surgeons were not statistically different in the groups of patients with (respectively, 12.11, 2.6 and 3.03) and without BS (respectively, 12.99, 2.7 and 2.96). More noteworthy, the false negative (FN) rate of the SLN technique, albeit having a higher observed value in the group with BS (9.6%, 12/125), did not differ significantly from that in the group without BS (5.6%, 2/36). The accuracies (overall correct classification rates), the sensitivities and the negative predictive values of the SLN technique also did not differ significantly between the two groups. It is concluded that the SLN technique can be accurately performed just after one BS.

RESUMEN

When many lymph nodes are found by using lymphoscintigraphic techniques performed to detect the sentinel lymph nodes (SLNs) in breast cancer, it is usual to find that the 'hottest' SLN is not always the node that is pathologically positive (pN+). Various criteria have been proposed to define which radioactive lymph nodes should be removed. In order to determine the frequency with which the hottest SLN 'fails' to be pN+, and to determine which criteria best define the radioactive lymph node to be removed, we reviewed and analysed our cases in which more than one SLN was detected and where there was also at least one pN+ node. From a series of 181 patients, 40 were selected. In 11 of these 40 cases (27.5%), the hottest SLN was not pN+. Radioactivity levels in the pN+SLN of these 11 patients ranged from 2% to 94% of the activity of the hottest SLN. Twenty-one patients (52.5%) showed only micrometastatic (pN1a) disease in one or more SLNs. In four of these patients (19%) the pN1a SLN was not the hottest node. Two of the patients had radioactivity levels in the pN+SLN which were more than 50% of that of the hottest SLN. In another two of these patients (9.5%), radioactivity levels were lower than 50% of that of the hottest node (respectively, 38% and 2%). However, in these two last cases, the first and hottest SLN removed surgically was found, by the pathologist, to consist of six nodes. Macrometastases (dimensions greater than 2 mm) were found in 19 patients. In 12 of these patients, the hottest SLN was macrometastatic although macrometastases and/or micrometastases were found in other 'cooler' SLNs in four of them. In another seven of these patients (36.8%), macrometastases were found in SLNs with radioactive levels lower than 51% of that of the hottest node. One patient (with three SLNs) out of the 40 (2.5%) had one SLN pN+ with less than 10% of that of the hottest. In fact, it contained only one micrometastasis and its activity was equal to 2%. Upon pathological examination, however, the hottest lymph 'node' was found to consist of six nodes. It is concluded that, with four intra-mammary and peritumoural injections of 99mTc labelled nanosized colloids of Human Serum Albumin (Nanocoll R: Sorin: 74 MBq and 0.05 mg per injection) performed 18-24 h before using a gamma probe to detect the SLNs, the hottest SLN was not the pathologically positive node in 27.5% of patients in our series. By using the activity in the hottest SLN as the reference point, and 10% of this activity as the lower threshold for removing active SLNs, the sensitivity of the technique is 97.5%.

RESUMEN

STUDY AIM: Determination of axillary lymph node status is crucial in diagnosis of early breast cancer. However thanks to an early diagnosis, an increasing number of axillary lymph node dissections are free of disease. This raises questions about the need for this procedure. The study aim was to report an experience with lymphadenectomy and sentinel node mapping in patients with T0-T1 carcinoma of the breast. METHODS: Between November 1997 and December 1999, 84 consecutive women (T0-T1 N0 according to the 1987 UICC classification) with recently diagnosed breast cancer, were included in this study for identification of the sentinel lymph node (SLN). The SLN was removed and submitted for histological examination. All patients underwent axillary dissection; nodes from levels I and II (Berg's classification) were excised and submitted to histological examination. RESULTS: The average tumor diameter was 12.7 mm (range, 3 to 25 mm). The lymphatic mapping technique was obtained after injection of the isotope into the breast around the tumor in 53/84 patients: the sentinel lymph node was the only positive node in 10 patients and it was positive in 5 patients with other axillary nodes. In 15/84 patients, an intradermal injection of blue dye was used; two sentinel nodes were positive and one falsely negative. In 16/84 patients, an interdermal injection of blue dye was used to make up for. In this study, the sentinel node was positive in three patients and falsely negative in one patient. The discrepancy was due to an important involvement of an axillary area excluded from the lymphatic channels. 22/84 patients (26%) had a metastatic spread to the axillary nodes. 30/84 patients had also an isotopic captation in another lymph node group (internal mammary). CONCLUSION: This study confirms that lymphatic mapping is technically possible in the patients with T0-T1 breast cancer and that the histological characteristics of the sentinel node probably reflect the histological characteristics of the rest of the axillary lymph nodes, but do not provide any information about the other lymph node sites.

RESUMEN

INTRODUCTION: The pregnancy-associated breast cancer seems to have become increasingly common with a high frequency of advanced breast cancer with axillary node metastases and so associated with poor prognosis. MATERIALS AND METHODS: This review examines the diagnosis, prognosis, and management of cancer during pregnancy; both in terms of the cancer's effect on the pregnancy, and the pregnancy's effect on the cancer. RESULTS: Diagnostic procedures (breast sonography) and excisional biopsies are necessary to reduce the delay of several months or more after discovery of a mass and before treatment. No histological difference, between patients with pregnancy-associated breast cancer and patients with non-pregnancy-associated breast cancer, was diagnosed. CONCLUSION: The treatment is linked to the effects of adjuvant therapy on the fetus.

RESUMEN

BACKGROUND/AIMS: Hepatocellular adenoma resection and focal nodular hyperplasia supervision are widely recognized as the best management when these benign liver tumors are diagnosed. Differential diagnosis is thus mandatory. METHODOLOGY: Twenty-nine patients with a presumed benign liver tumor were retrospectively analyzed. RESULTS: Histopathological analysis of these resected liver tumors demonstrated hepatocellular adenoma in 16 patients and focal nodular hyperplasia in 13. One hepatocellular carcinoma was disclosed into a hepatocellular adenoma and 2 hepatocellular adenoma showed foci of liver-cell dysplasia. Seven patients with hepatocellular adenoma (43%) had evidence of intratumoral hemorrhage, among which 3 patients were admitted with intraperitoneal tumoral rupture. Computed tomography, performed in 26 patients, was the most reliable examination to characterize these presumed benign liver tumors. Magnetic resonance imaging concerned only 5 patients but 3 hepatocellular adenoma and 1 focal nodular hyperplasia were diagnosed. The indications of focal nodular hyperplasia surgical resection were chronic pain (4 pts), hepatocellular adenoma diagnosis (4 pts), undeterminate liver mass (2 pts), a liver mass of unknown origin in patients with a neoplastic history (3 pts). A diagnosis of focal nodular hyperplasia assumed by the imaging work-up was always histologically confirmed. All the patients underwent hepatic resection with no mortality. CONCLUSIONS: This report underlines the risk of hemorrhage or malignant transformation of hepatocellular adenoma that justifies a safety surgical resection. An imaging work-up in favor of focal nodular hyperplasia allows radiological observation.

RESUMEN

From 1974 till 1993, 9 patients have been treated in our Hospital for a breast cancer. Compared with the amount of women breast cancers treated, actually near 300 per year, this 0.3% figure seems small, and is lower than that found in the literature (1%). The therapeutic attitude is the same as that proposed for women. The follow-up varied from 9 to 120 months with a mean of 57. Five patients are actually still living without recurrence. One patient presented a local recurrence, one was lost sight off and two died from their cancer. Despite the fact that it was a small group of patients we can say that the symptoms, the clinical staging, the proposed treatments and the survival rate are the same as found in the literature.

RESUMEN

Diaphragmatic rupture occurs in 25% of the thoracic and abdominal blunt injuries. It may be discovered immediately or sometimes several months or even years after the trauma. The diagnosis can be made easily on the basis of a standard chest X-ray. Barium swallow examination, computerized tomography Scan and especially Magnetic resonance imaging can be helpful for differential diagnosis. Surgical treatment is always necessary.

RESUMEN

Between 1988 and 1991, at the Jules Bordet Institute in Brussels, 11 patients were submitted to a surgical treatment due to an uterus cervix central recurrence. The majority were of the epidermoid type. The primary stage of the lesion at the moment of diagnosis varied from stage Ib to stage IIIb lesions. Six of the eleven patients were not submitted to an adequate initial treatment. These recurrences appeared between the 4th and the 264th month after the initial treatment. The treatments, which were determined according to the site of recurrence, consisted of: an anterior pelvic exenteration for four patients, a total exenteration for one patient, for two of them a total hysterectomy with bilateral salpingo-oophorectomy and partial cystectomy, a cervix amputation for another one and finally, for the last three ones, a laparotomy with debulking or derivation colostomy. The mortality during and after the operation was nil but there were several short term complications. After a minimal 19 months follow-up we could see that three patients survived, one was generalized and seven died. Due to the scarce number of patients and pathological disparity of them, the authors reviewed the literature concerning this problem, in order to determine some guidelines for similar cases. In spite of its consequences, surgery seems to be the only valid solution to propose to these patients, not only to give them a chance to survive but also to improve their life quality.
