RESUMO

PURPOSE: Breast cancer is the most common malignancy in women in terms of incidence and mortality. Age is undoubtedly the biggest breast cancer risk factor. In this study we examined clinical, histological, and biological characteristics and mortality of breast cancer in elderly women along with their changes with advancing age. METHODS: We reviewed 63 original articles published between 2006 and 2016 concerning women over 70 years with breast cancer. RESULTS: Compared to patients 70-79 years, patients aged 80 and over had larger tumor size with fewer T1 (42.9% vs 57.7%, p < 0.01) and more T2 lesions (43.5% vs 33.0%, p < 0.01). Lymph nodes and distant metastases were more frequent, with more N + (49.5% vs 44.0%, p < 0.01) and more M1 (8.0% vs 5.9%, p < 0.01). Infiltrating mucinous carcinomas were more frequent (4.3% vs 3.7%, p < 0.01). Tumors had lower grades, with more grade 1 (23.2% vs 19.8%, p = 0.01) and fewer grade 3 (21.5% vs 25.5%, p < 0.01), and were more hormone-sensitive: PR was more often expressed (72.6% vs 67.3%, p < 0.01). Lympho-vascular invasion was less frequent in the 80 years and over (22.9% vs 29.7%, p = 0.01). Breast cancer-specific mortality was higher both at 5 years (25.8% vs 17.2%, p < 0.01) and 10 years (32.7% vs 26.6%, p < 0.01). CONCLUSION: Clinico-pathological characteristics, increased incidence, and mortality associated with aging can be explained on one hand by biological changes of the breast such as increased estrogen sensitivity, epithelial cell alterations, immune senescence, and tumor microenvironment modifications. However, sociologic factors such as increased life expectancy, under-treatment, late diagnosis, and insufficient individual screening, are also involved.

RESUMO

BACKGROUND: This study was designed to evaluate detection rate and anatomical location of sentinel lymph node (SLN) at lymphoscintigraphy, to compare short and long lymphoscintigraphy protocols, and to correlate lymphoscintigraphic and surgical mapping of SLN in patients with early-stage endometrial cancer (EC). METHODS: Subanalysis of the prospective multicenter study Senti-endo performed from July 2007 to August 2009. Patients with stage I and II EC received four cervical injections of 0-2 mL of unfiltered technetium sulphur colloid the day before (long protocol) or the morning (short protocol) before surgery. SLN detection used a combined technetium/patent blue labeling technique, and all patients had a systematic bilateral pelvic lymphadenectomy. RESULTS: A total of 133 patients were enrolled in the study and 118 (94.5 %) underwent a lymphoscintigraphy. Of these 118 patients, 44 (37 %) underwent a short protocol and 66 (56 %) a long protocol (data on lymphoscintigraphy were not available in eight patients). Lymphoscintigraphic detection rate was 74.6 % (34 % for short protocol and 60.2 % for long protocol). No difference in the detection rate was observed according to lymphoscintigraphy protocol (p = 0.22), but a higher number of SLN was noted for the long protocol (p = 0.02). Aberrant drainage was noted on lymphoscintigraphy in 30.5 % of the patients. Paraaortic SLNs were exclusively detected using the long protocol. A poor correlation was noted between short (κ test = 0.24) or long lymphoscintigraphy (κ test = 0.3) protocol and SLN surgical mapping. CONCLUSIONS: Our study demonstrates that preoperative lymphoscintigraphy allowed a high SLN detection rate and that long lymphoscintigraphy protocol was associated with a higher detection of aberrant drainage especially in the paraaortic area.

RESUMO

BACKGROUND: We developed a nomogram based on five clinical and pathological characteristics to predict lymph-node (LN) metastasis with a high concordance probability in endometrial cancer. Sentinel LN (SLN) biopsy has been suggested as a compromise between systematic lymphadenectomy and no dissection in patients with low-risk endometrial cancer. METHODS: Patients with stage I-II endometrial cancer had pelvic SLN and systematic pelvic-node dissection. All LNs were histopathologically examined, and the SLNs were examined by immunohistochemistry. We compared the accuracy of the nomogram at predicting LN detected with conventional histopathology (macrometastasis) and ultrastaging procedure using SLN (micrometastasis). RESULTS: Thirty-eight of the 187 patients (20%) had pelvic LN metastases, 20 had macrometastases and 18 had micrometastases. For the prediction of macrometastases, the nomogram showed good discrimination, with an area under the receiver operating characteristic curve (AUC) of 0.76, and was well calibrated (average error =2.1%). For the prediction of micro- and macrometastases, the nomogram showed poorer discrimination, with an AUC of 0.67, and was less well calibrated (average error =10.9%). CONCLUSION: Our nomogram is accurate at predicting LN macrometastases but less accurate at predicting micrometastases. Our results suggest that micrometastases are an 'intermediate state' between disease-free LN and macrometastasis.

RESUMO

BACKGROUND: The objective of the study was to identify factors predictive of 6-month institutionalization or mortality in frail elderly patients after acute hospitalization. METHODS: A prospective cohort of elderly subjects 75 years and older was set up in nine French teaching hospitals. Data obtained from a comprehensive geriatric assessment were used in a Cox model to predict 6-month institutionalization or mortality. Institutionalization was defined as incident admission either to a nursing home or other long-term care facility during the follow-up period. RESULTS: Crude institutionalization and death rates after 6 months of follow-up were 18% and 24%, respectively. Independent predictors of institutionalization were: living alone (HR=1.83; 95% CI=1.27-2.62) or a higher number of children (HR=0.86; 95% CI=0.78-0.96), balance problems (HR=1.72; 95% CI=1.19-2.47), malnutrition or risk thereof (HR=1.93; 95% CI=1.24-3.01), and dementia syndrome (HR=1.88; 95% CI=1.32-2.67). Factors found to be independently related to 6-month mortality were exclusively medical factors: malnutrition or risk thereof (HR=1.92; 95% CI=1.17-3.16), delirium (HR=1.80; 95% CI=1.24-2.62), and a high level of comorbidity (HR=1.62; 95% CI=1.09-2.40). Institutionalization (HR=1.92; 95% CI=1.37-2.71) and unplanned readmission (HR=4.47; 95% CI=3.16-2.71) within the follow-up period were also found as independent predictors. CONCLUSION: The main factors predictive of 6-month outcome identified in this study are modifiable by global and multidisciplinary interventions. Their early identification and management would make it possible to modify frail elderly subjects' prognosis favorably.

RESUMO

The fragile X syndrome, a common cause of inherited mental retardation, is characterized by an unusual mode of inheritance. Phenotypic expression has been linked to abnormal cytosine methylation of a single CpG island, at or very near the fragile site. Probes adjacent to this island detected very localized DNA rearrangements that constituted the fragile X mutations, and whose target was a 550-base pair GC-rich fragment. Normal transmitting males had a 150- to 400-base pair insertion that was inherited by their daughters either unchanged, or with small differences in size. Fragile X-positive individuals in the next generation had much larger fragments that differed among siblings and showed a generally heterogeneous pattern indicating somatic mutation. The mutated allele appeared unmethylated in normal transmitting males, methylated only on the inactive X chromosome in their daughters, and totally methylated in most fragile X males. However, some males had a mosaic pattern. Expression of the fragile X syndrome thus appears to result from a two-step mutation as well as a highly localized methylation. Carriers of the fragile X mutation can easily be detected regardless of sex or phenotypic expression, and rare apparent false negatives may result from genetic heterogeneity or misdiagnosis.

RESUMO

Yeast artificial chromosomes (YACs) were obtained from a 550-kilobase region that contains three probes previously mapped as very close to the locus of the fragile X syndrome. These YACs spanned the fragile site in Xq27.3 as shown by fluorescent in situ hybridization. An internal 200-kilobase segment contained four chromosomal breakpoints generated by induction of fragile X expression. A single CpG island was identified in the cloned region between markers DXS463 and DXS465 that appears methylated in mentally retarded fragile X males, but not in nonexpressing male carriers of the mutation nor in normal males. This CpG island may indicate the presence of a gene involved in the clinical phenotype of the syndrome.

RESUMO

Fragile-X syndrome, the most common inherited form of mental retardation, has a very unusual mode of inheritance. The disease is caused by a multistep expansion, in successive generations, of a polymorphic CGG repeat localized in a 5' exon of FMR-1, a gene of unknown function. Two main mutation types have been categorized. Premutations are moderate expansions of the repeat and do not cause mental retardation. Full mutations are found in affected individuals and involve larger expansions of the repeat, with abnormal methylation of the neighboring CpG island. The full mutations demonstrate striking somatic instability and extinguish expression of FMR-1. Premutations are changed to full mutation only when transmitted by a female with a frequency that increases up to 100% as a function of the initial size of the premutation. Direct detection of the mutations provides an accurate test for pre- and postnatal diagnosis of the disease, and for carrier detection. A similar unstable expansion of a trinucleotide repeat occurs in myotonic dystrophy.

RESUMO

To identify predictive factors for 2-year mortality in frail elderly patients after acute hospitalisation, and from these to derive and validate a Mortality Risk Index (MRI). A prospective cohort of elderly patients was set up in nine teaching hospitals. This cohort was randomly split up into a derivation cohort (DC) of 870 subjects and a validation cohort (VC) of 436 subjects. Data obtained from a Comprehensive Geriatric Assessment were used in a Cox model to predict 2-year mortality and to identify risk groups for mortality. A ROC analysis was performed to explore the validity of the MRI. Five factors were identified and weighted using hazard ratios to construct the MRI: age 85 or over (1 point), dependence for the ADL (1 point), delirium (2 points), malnutrition risk (2 points), and co-morbidity level (2 points for medium level, 3 points for high level). Three risk groups were identified according to the MRI. Mortality rates increased significantly across risk groups in both cohorts. In the DC, mortality rates were: 20.8% in the low-risk group, 49.6% in the medium-risk group, and 62.1% in the high-risk group. In the VC, mortality rates were respectively 21.7, 48.5, and 65.4%. The area under the ROC curve for overall score was statistically the same in the DC (0.72) as in the VC (0.71). The proposed MRI appears as a simple and easy-to-use tool developed from relevant geriatric variables. Its accuracy is good and the validation procedure gives a good stability of results.

RESUMO

OBJECTIVES: The purpose of the study was to compare the postoperative pain of patients who had a hysterectomy through vaginal route according to the process of binding: wire or electrosurgical bipolar vessel sealing. PATIENTS AND METHODS: Retrospective study carried out in the 60 last patients who underwent a hysterectomy by vaginal route for a benign pathology in the gynaecological service of surgery of the CHI Poissy-Saint-Germain-en-Laye until March 2006. Among these patients, 32 had profited from a binding by wire and 28 of the electrosurgical bipolar vessel sealing. The studied criteria were the post-operative pain, total morphine consumption and the durations of the analgesic treatment, the hospitalisation and intervention time. RESULTS: The postoperative pain in the first 24 hours was twice lower using thermofusion; it was valid in immediate post-operative period and after 24 hours. In addition, total morphine consumption was also significantly lower using thermofusion. DISCUSSION AND CONCLUSION: This pilot study shows that the electrosurgical bipolar vessel sealing allows a reduction in the pain into the immediate postoperative period. Other prospective and randomised studies would allow it and conclude on the duration of hospitalisation, the quality of life from the patients and the cost in terms of public health.

RESUMO

Differential display-polymerase chain reaction (DD-PCR) was used to evaluate changes in mRNA expression of granulocyte-macrophage colony-stimulating factor (GM-CSF) treated human neutrophils to better understand how this cytokine affects the functions of neutrophils at the molecular level. Although a variety of cDNA fragments were identified as modulated by GM-CSF with the use of DD-PCR, one fragment in particular, NGS-17 (neutrophil GM-CSF-stimulated fragment #17), was characterized. The NGS-17 fragment hybridized to a 3.8-kh mRNA that encodes for a protein of a predicted molecular mass of 47.6 kDa. After cloning and sequencing, this gene was found to code for the recently sequenced tapasin or TAP-A protein. Immunoprecipitation and immunoblotting studies using anti-tapasin antibodies showed that tapasin is expressed in neutrophils and is associated with the MHC class I-TAP complex. Moreover, tapasin expression was found to be induced by dimethyl sulfoxide and by retinoic acid in HL-60 cells. This is the first report on the expression of tapasin in human neutrophils. It provides novel information, at the molecular level, on how GM-CSF enhances the functions of these cells.

RESUMO

OBJECTIVE: Our aim was to describe the living conditions of disabled elderly subjects aged 75 years and more living at home. DESIGN: This study was conducted in 1996-97 in the Alsace region in France and included two parts. First, a sample survey was mailed to 15,600 subjects randomly selected from a pension funds list. This survey provided with a reliable representation of the study population in terms of disabilities using the Colvez classification. In the second part, the most disabled individuals were selected and, among them, 1,259 subjects were visited at home. Their disabilities and living conditions were noted using a predefined set of questions. RESULTS: An estimated 71,000 subjects aged 75 years and more lived at home in the study region. The vast majority were free of significant disability. Help to wash and dress was needed by 6,000 until 1,500 were bedridden or confined to an armchair. Between 4,350 and 5,400 met the criteria for iso-resource grades (IRG) 1 to 3. Disability was associated with age, female gender, cognitive impairment and some social and professional characteristics. Family support was routine in almost every aspect of everyday life including personal hygiene. Professional support was mostly limited to technical interventions. Professional nursing care concerned only the most dependent persons. Nevertheless, needs for help in home and social activities remained high even in the least dependent individuals and were strongly age-dependent. Only 10% of individuals with IRG 1 to 3 complained of inadequate help. More than 80% of the elderly felt comfortable with their living conditions at home and were not thinking of moving from home to an institution for old people. CONCLUSION: The present study confirms the important commitment of family members and their close relationships toward their elderly.

RESUMO

Direct DNA analysis of fragile X [Fra(X)] mutations has already shown its clear superiority for postnatal and prenatal diagnosis of the disorder and for carrier detection. However, it is of great importance to have conditions which guarantee optimal reliability and sensitivity. Some mutations may be more difficult to detect, especially in female carriers: this is the case for small amplifications of the CGG repeat (premutations) or for smears which can be generated by the instability of the full mutation in somatic tissues. We present the various alternatives (probe/enzymes combinations) for Southern blot based diagnosis, the possible artefacts and our detailed experimental protocol, which has given excellent results on a large number of families. While detection of amplification, using for instance EcoRI, appears sufficient for initial testing of mentally retarded patients, once the fra(X) diagnosis has been established, we favor the use of an EcoRI+EagI digest, which detects both amplification and abnormal methylation, for analysis of the family, including carrier detection and prenatal diagnosis. We discuss the place of proposed PCR based techniques for detection of mutations, or for indirect tracking using polymorphic microsatellites in the immediate vicinity of the fra(X) locus.

RESUMO

We have reinvestigated 33 fragile X families using probe StB12.3. In 31 families the affected individual showed an insert while in 2 families no insert was detected. The insert fell into two size categories: small (less than 0.5 kb); and large (greater than 0.6 kb) accompanied by methylation of an EagI site. All individuals of either sex having a small insert were fra(X) negative and intellectually normal, while all males having a large insert were fra(X) positive and intellectually impaired. Females having a large insert were either fra(X) positive or negative and either intellectually normal or impaired. No new mutation was found. All daughters of males with a small insert had a small insert; females with a large insert produced males and females who had a large insert, while females with a small insert had offspring with either a large or a small insert. However, females with a small insert tended to fall into one of two categories: either they had only children with a small insert or only children with a large insert, there being only one exception to this rule. We found four unexpected small inserts, two in unrelated spouses and two in female carriers who proved to be compound heterozygotes, indicating that they had inherited an insert from both their parents. These observations suggest that individuals with a small insert must be not uncommon in the general population.

RESUMO

PURPOSE: Most of the antibiotic-associated diarrhea (AAD) cases result from a transient disturbance in the function of the normal intestinal flora and are spontaneously solved when discontinuing the antibacterial therapy. However, a mild diarrhea lasting several days may induce a dehydration or worsen a denutrition in frail elderly people. CURRENT KNOWLEDGE AND KEY POINTS: The incidence of AAD varies between 5 and 25% depending on the concerned antibiotic. Only 10-20% of all AAD cases are caused by infection, especially with Clostridium difficile, for which advanced age is a major risk factor. The first biological exam to perform when severe AAD or in frail people is the detection of C. difficile toxins, especially in elderly patient treated with beta-lactam antibiotics. Nevertheless, other infectious organisms causing AAD may be considered, as Staphylococcus aureus when predominant in stool cultures from patients treated with fluoroquinolones or as Klebsiella oxytoca when isolated in bloody diarrhea from patients treated with ampicillin. Elevated fecal counts of Candida spp. found in patients treated with antibiotics is rather the consequence of therapy than the cause of AAD. The prevention of AAD is based on a rational antibiotic use to avoid endogenous selection of C. difficile and on the improvement of the hygiene measures to limit the exogenous transmission of the bacteria or related spores by spoiled hands. FUTURE PROSPECTS: Simultaneous prescription of non-pathogenic living organisms, capable of re-establishing the equilibrium of the intestinal flora, should be better described, especially in elderly people, because of its important economic impact.

RESUMO

INTRODUCTION: Candidemia, principally affecting neutropenic patients in departments of oncohematology and frail patients in intensive care units, can also be observed in frail elderly people in geriatrics. EXEGESIS: Authors report four observations of candidemia diagnosed in elderly dependent patients having several different diseases. Clinical sign was a persistent or recurrent fever after a wide-spectrum antibiotic therapy. Patients were treated by fluconazole leading to negative blood cultures in several days. Three out of four patients died within the weeks following antifungal therapy due to severity of associated diseases. CONCLUSION: These observations show that a diagnosis of candidemia should be made when a persistent fever is observed in a frail elderly person. Fluconazole, as efficient as amphotericin B and well tolerated by elderly people, should be the first treatment of candidemia in non-neutropenic patients.

RESUMO

PURPOSE: Spontaneous fractures (stress and bone insufficiency fractures) are well described in young healthy patients; however, few studies were conducted in the elderly. METHODS: A 30-month prospective clinical and epidemiological survey including elderly patients from long-term nursing homes (LTNH) of the Société de Gérontologie de l'Est (70 centers; 11,495 elderly patients in total) was conducted. RESULTS: Sixty-seven spontaneous fractures were encountered in 30 LTNH (3,052 elderly patients) (five stress fractures of the foot, 62 bone insufficiency fractures). The mean age of bedridden patients was 85 +/- 7 years. The prevalence of spontaneous fractures (calculated from the number of patients admitted consecutively in LTNHs) was 0.34% in the whole population (11,495 beds). When the calculation was based on LTNH reports of spontaneous fractures (3,052 elderly patients), the prevalence reached 1.3%. Fractures of long bones were common in elderly patients and included 15 fractures of the femoral neck, 14 fractures of either the tibia or fibula, 13 fractures of the femoral shaft, and 11 fractures of the humerus. Fractures of the femoral shaft were associated with the highest mortality: seven out of 13 patients died versus two out of 15 patients with regard to fractures of the femoral neck (P < 0.05). CONCLUSION: Bone insufficiency fractures have not the same course in young healthy patients as those in elderly nursing home patients: they more often concern long bones and their prognosis is worse. Means of prevention still have to be defined.

RESUMO

OBJECTIVE: To evaluate mid term results, tolerance and efficiency of interposition of a tension-free polypropylene monofilament mesh by vaginal approach for the repair of cystoceles. PATIENTS AND METHODS: Fourty consecutive women underwent this new procedure between March 2001 and September 2002. After complete dissection of the cystocele, the polypropylene mesh (Gynemesh), Gynecare, Ethicon, Johnson & Johnson, France), proper cut-out was positioned under the bladder without any fixation. The lateral extensions of the mesh where introduced in the para-vesical spaces in contact with the arcus tendinus fascia pelvis. RESULTS: Before surgery all patients had cystocele of more or equal than grade II according to the POP-Q classification. Eight had grade II cystocele (20%) and 32 had grade III cystocele (80%). Thirty women had associated posterior or median prolapse (82.5%). Thirty women had urinary incontinence (75%). Mean age was 63.9 years (51-78). The procedure was performed without any difficulty in all cases. Duration of a cystocele cure procedure was 20 min +/- 2.2 (16-24). Mean follow-up is 16.4 months +/- 4.7 (12-24). The early complication rate was 7.5% (two vaginal erosions and one complete exposition of the mesh which requires secondary ablation). There was no mesh infection. The success rate was 95%. The satisfaction index overpasses 80% in 95% of our patients 6 months after the cystocele repair. DISCUSSION AND CONCLUSIONS: The interposition of a sub-vesical transversal tension-free polypropylene mesh by the vaginal route seems to be an excellent procedure in the definitive surgical treatment of grades II and III anterior vaginal wall prolapse. This new procedure is simple, mini-invasive, reproducible and efficient with low morbidity and good tolerance.

RESUMO

Clinical examination (history and physical examination) is not considered to be a useful tool in the diagnosis of ectopic pregnancy (EP). In this systematic review we aimed to evaluate its value when ancillary tests are not readily available or when they are equivocal. Suspicion of EP is based on the presence of one or more of the following signs: vaginal bleeding, acute pelvic pain, or any risk factors for EP occurring in a pregnant woman. Detection of early pregnancy by urinary or serum hCG testing must be systematic because neither medical history nor physical examination can rule out early pregnancy with a high level of confidence. No isolated sign has sufficient diagnostic accuracy to rule out EP. In presence of vaginal bleeding without pain and if abdominal and pelvic examination are normal the risk of EP is very low. The presence of spontaneous pain moderate to severe, peritoneal signs, or definite pain during digital cervical mobilization increase the probability of EP. Absence of these signs does not rule out EP but tend to eliminate tubal rupture. In the presence of these signs one may consider an emergency transfer in a specialized center. In their absence, suspicion of EP may have outpatient diagnosis procedures.

RESUMO

Advances in laboratory tests and transvaginal ultrasound have enabled very early diagnosis of ectopic pregnancy. Expectative management has progressively become a real medical option for ectopic pregnancies as an alternative to surgery or medical treatment. The decision to abstain from treatment must be based on very strict criteria: patients with no symptoms, hematosalpinx<3 cm, no hemoperitoneum, hCG level<1000 mUI/ml and decreasing 48 hours later, a progesterone level<10 ng/ml. Regular surveillance until normalization of clinical, ultrasound and biological results is essential. The rate of success, which reaches 90%, clearly justifies this medical option.

RESUMO

BACKGROUND: The aim of the study was to evaluate the safety and efficacy of the Musset Poitout surgical procedure consisting in an anterior uterosacral ligament transposition and a cervix amputation. The main indication is an uterovaginal prolapse with an isolated elongation of the cervix. METHODS: A retrospective consecutive series of 20 women with an elongation of uterine cervix undergoing Musset Poitout procedure over a 10 year period between 1990 and 2001 with analysis of per and post operative complications and success. Four Kelly urethral plications were performed in the same time. The patient's ages, time under anesthesia, change in hemoglobin, days of hospitalization, medical illnesses, complications and follow-up were assessed. Failure was defined as a symptomatic elongation of the cervix or a third degree hysterocele on examination. RESULTS: and discussion. The median age of Musset Poitout procedure was 43.9 years (range 23-83). General anaesthesia could be performed in all patients. Mean operation time was 67 minutes (range 40-130). No major per or post operative complications occurred. The average of post-operative bladder cathetherisation was 3.65 days, the average hospital stay was 6.3 days. Complications were insignificant: urinary tract infection in 2, voiding dysfunction in 2. All the patients but 2 were followed for a mean 59 months (range 6-127). There was one recurence (5.5%). CONCLUSION: In this preliminary assessment the Musset Poitout procedure offered significant avantages in a genital prolapse with elongation of the cervix.
