RESUMO

BACKGROUND: This study aims to explore the emotional and behavioural responses and coping strategies of fathers or expectant fathers who faced a significant traumatic event during a partner's pregnancy, labour, or the postpartum period. METHODS: This prospective qualitative study of 24 fathers was conducted at a public teaching hospital in Brisbane, Australia. 'Traumatic pregnancy' was defined as a pregnancy complicated by life-threatening or severe risk to the mother and the fetus, termination of pregnancy, intrauterine fetal death or stillbirth. Semi-structured interviews of participants were conducted 3-4 months after the traumatic event. An initial qualitative analysis with automatic coding was performed using Leximancer and later followed by a six-phase manual thematic analysis. RESULTS: A pregnancy-related traumatic event had significant mental and physical impacts on fathers. Participants' reactions and coping strategies were varied and influenced by their background history, pre-existing vulnerabilities, and the gap between expectation and reality. Most fathers described a fluctuating state between their needs 'not being met' and 'being met'. These needs were conceptualised using Maslow's hierarchy and Calman's gap theory to construct a composite thematic model to depict the universal requirements of men facing a traumatic pregnancy or childbirth. CONCLUSIONS: A greater understanding of the needs of men and gaps in their care is urgently needed. A targeted effort is required to make maternity services father-inclusive. This approach may assist in preventing long term consequences on fathers, partners, and their children.

RESUMO

BACKGROUND: This study aims to explore the prevalence of symptoms of depression and traumatic stress in fathers in the setting of poor fetal, neonatal, and maternal outcomes. METHODS: A prospective mixed-methods study was conducted at an outer metropolitan public teaching hospital in Brisbane, Australia, with quantitative results presented here. Subjects included 28 fathers whose male partners had experienced pregnancy or childbirth complicated by a significant congenital abnormality or aneuploidy, termination of pregnancy, fetal death in-utero, stillbirth, admission to the neonatal intensive care unit or special care nursery or significant maternal morbidity, such as a postpartum haemorrhage or an emergency postpartum hysterectomy. These experiences were classified into two groups: anticipatory (time to prepare) and sudden (no warning). The fathers were screened using the Edinburgh Postnatal Depression Scale (EPDS) and the Impact of Events Scale-Revised (IES-R) to assess subjective distress at 2-3 weeks (timepoint 1) and 3-4 months (timepoint 2) after the event. RESULTS: Data for both the EPDS and IES-R scales was available for 26 fathers (92.9%) at timepoint 1 and for 15 fathers (53.6%) at timepoint 2. High overall EPDS scores (≥10) were noted in 16/27 (59.3%) fathers at timepoint 1 and 6/15 fathers (40.0%) at timepoint 2. High overall IES-R scores ≥33 were noted in 12/26 (46.2%) fathers at timepoint 1 and 4/15 fathers (26.7%) at timepoint 2. A higher percentage of fathers who experienced anticipatory events had EPDS and IES-R score above these cut-offs at timepoint 1 (8/13 or 61.5%) compared to those experiencing sudden events (8/14 or 57.1%), however, percentages were similar between groups at time point 2 (2/7 or 28.6%% and 4/8 or 50.0%, respectively). More fathers who experienced anticipatory events had IES-R scores ≥33 at timepoint 1 (7/13 or 53.8%) compared to those experiencing sudden events (5/14 or 38.0%). CONCLUSION: Our study indicates high rates of distress in fathers exposed to poor fetal, neonatal, and maternal outcomes, which can persist for months after the event. Increased support for fathers in this setting may be required to prevent poor mental health. Further research on the long-term effects of these adverse events is warranted.

RESUMO

BACKGROUND: Integrated knowledge translation (IKT) is a model of research co-production, whereby researchers partner with knowledge users throughout the research process and who can use the research recommendations in practice or policy. IKT approaches are used to improve the relevance and impact of research. As an emerging field, however, the evidence underpinning IKT is in active development. The Integrated Knowledge Translation Research Network represents a collaborative interdisciplinary team that aims to advance the state of IKT science. METHODS: In 2017, the Integrated Knowledge Translation Research Network issued a call to its members for concept papers to further define IKT, outline an IKT research agenda, and inform the Integrated Knowledge Translation Research Network's special meeting entitled, Integrated Knowledge Translation State of the Science Colloquium, in Ottawa, Canada (2018). At the colloquium, authors presented concept papers and discussed knowledge-gaps for a research agenda and implications for advancing the IKT field. We took detailed field notes, audio-recorded the meeting and analysed the data using qualitative content analysis. RESULTS: Twenty-four participants attended the meeting, including researchers (n = 11), trainees (n = 6) and knowledge users (n = 7). Seven overarching categories emerged from these proceedings - IKT theory, IKT methods, IKT process, promoting partnership, definitions and distinctions of key IKT terms, capacity-building, and role of funders. Within these categories, priorities identified for future IKT research included: (1) improving clarity about research co-production/IKT theories and frameworks; (2) describing the process for engaging knowledge users; and (3) identifying research co-production/IKT outcomes and methods for evaluation. CONCLUSION: The Integrated Knowledge Translation State of the Science Colloquium initiated a research agenda to advance IKT science and practice. Next steps will focus on building a theoretical and evidence base for IKT.

RESUMO

Avoidance of general anaesthesia for breast surgery may be because of clinical reasons or patient choice. There is emerging evidence that the use of regional anaesthesia and the avoidance of volatile anaesthetics and opioid analgesia may have beneficial effects on oncological outcomes. We conducted a prospective observational case series of 16 breast cancer surgeries performed under thoracic paravertebral plus pectoral nerve block with propofol sedation to demonstrate feasibility of technique, patient acceptability and surgeon satisfaction. Fifteen out of 16 cases were successfully completed under sedation and regional anaesthesia, with one conversion to general anaesthesia. Eleven out of 16 cases required low-dose intra-operative opioid analgesia. Out of the 15 surgical procedures completed under regional anaesthesia with sedation, all patients experienced either no or minimal intra-operative pain, and all would choose this anaesthetic technique again. Surgeon-reported operating conditions were 'indistinguishable from general anaesthesia' in most cases, and surgeons were 'extremely satisfied' or 'satisfied' with the technique after every procedure. Combined thoracic paravertebral plus pectoral nerve block with intra-operative sedation is a feasible technique for breast surgery.

RESUMO

STUDY QUESTION: What are the adverse outcomes associated with using the M4 model in everyday clinical practice for women with pregnancy of unknown location (PUL)? SUMMARY ANSWER: There were 17/835 (2.0%) adverse events and no serious adverse events associated with the performance of the M4 model in clinical practice. WHAT IS KNOWN ALREADY: The M4 model has previously been shown to stratify women classified as a PUL as at low or high risk of complications with a good level of test performance. The triage performance of the M4 model is better than single measurements of serum progesterone or the hCG ratio (serum hCG at 48 h/hCG at presentation). STUDY DESIGN, SIZE, DURATION: A prospective multi-centre cohort study of 1022 women with a PUL carried out between August 2012 and December 2013 across 2 university teaching hospitals and 1 district general hospital. PARTICIPANTS/MATERIALS, SETTING, METHODS: All women presenting with a PUL to the early pregnancy units of the three hospitals were recruited. The final outcome for PUL was either a failed PUL (FPUL), intrauterine pregnancy (IUP) or ectopic pregnancy (EP) (including persistent PUL (PPUL)), with EP and PPUL considered high-risk PUL. Their hCG results at 0 and 48 h were entered into the M4 model algorithm. If the risk of EP was ≥5%, the PUL was predicted to be high-risk and the participant was asked to re-attend 48 h later for a repeat hCG and transvaginal ultrasound scan by a senior clinician. If the PUL was classified as 'low risk, likely failed PUL', the participant was asked to perform a urinary pregnancy test 2 weeks later. If the PUL was classified as 'low risk, likely intrauterine', the participant was scheduled for a repeat scan in 1 week. Deviations from the management protocol were recorded as either an 'unscheduled visit (participant reason)', 'unscheduled visit (clinician reason)' or 'differences in timing (blood test/ultrasound)'. Adverse events were assessed using definitions outlined in the UK Good Clinical Practice Guidelines' document. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 835 (82%) women classified as a PUL were managed according to the M4 model (9 met the exclusion criteria, 69 were lost to follow-up, 109 had no hCG result at 48 h). Of these, 443 (53%) had a final outcome of FPUL, 298 (36%) an IUP and 94 (11%) an EP. The M4 model predicted 70% (585/835) PUL as low risk, of which 568 (97%) were confirmed as FPUL or IUP. Of the 17 EP and PPUL misclassified as low risk, 5 had expectant management, 7 medical management with methotrexate and 5 surgical intervention.Nineteen PUL had an unscheduled visit (participant reason), 38 PUL had an unscheduled visit (clinician reason) and 68 PUL had deviations from protocol due to a difference in timing (blood test/ultrasound).Adverse events were reported in 26 PUL and 1 participant had a serious adverse event. A total of 17/26 (65%) adverse events were misclassifications of a high risk PUL as low risk by the M4 model, while 5/26 (19%) adverse events were related to incorrect clinical decisions. Four of the 26 adverse events (15%) were secondary to unscheduled admissions for pain/bleeding. The serious adverse event was due to an incorrect clinical decision. LIMITATIONS, REASONS FOR CAUTION: A limitation of the study was that 69/1022 (7%) of PUL were lost to follow-up. A 48 h hCG level was missing for 109/1022 (11%) participants. WIDER IMPLICATIONS OF THE FINDINGS: The low number of adverse events (2.0%) suggests that expectant management of PUL using the M4 prediction model is safe. The model is an effective way of triaging women with a PUL as being at high- and low-risk of complications and rationalizing follow-up. The multi-centre design of the study is more likely to make the performance of the M4 model generalizable in other populations. STUDY FUNDING/COMPETING INTERESTS: None. TRIAL REGISTRATION NUMBER: Not applicable.

RESUMO

Lasiodiplodia species are environmental fungi that have been reported as a cause of infection in both immunocompetent and immunocompromised patients. We present a case of fungal osteomyelitis caused by Lasiodiplodia species in a patient with multiple myeloma after autologous stem cell transplant. The patient was successfully treated with a combination of surgery and oral voriconzole. To the best of our knowledge, this is the first reported case of fungal osteomyelitis caused by Lasiodiplodia species.

RESUMO

BACKGROUND: Knowledge translation and evidence-based practice have relied on research derived from clinical trials, which are considered to be methodologically rigorous. The result is practice recommendations based on a narrow view of evidence. We discuss how, within a practice environment, in fact individuals adopt and apply new evidence derived from multiple sources through ongoing, iterative learning cycles. DISCUSSION: The discussion is presented in four sections. After elaborating on the multiple forms of evidence used in practice, in section 2 we argue that the practitioner derives contextualized knowledge through reflective practice. Then, in section 3, the focus shifts from the individual to the team with consideration of social learning and theories of practice. In section 4 we discuss the implications of integrative and negotiated knowledge exchange and generation within the practice environment. Namely, how can we promote the use of research within a team-based, contextualized knowledge environment? We suggest support for: 1) collaborative learning environments for active learning and reflection, 2) engaged scholarship approaches so that practice can inform research in a collaborative manner and 3) leveraging authoritative opinion leaders for their clinical expertise during the shared negotiation of knowledge and research. Our approach also points to implications for studying evidence-informed practice: the identification of practice change (as an outcome) ought to be supplemented with understandings of how and when social negotiation processes occur to achieve integrated knowledge. This article discusses practice knowledge as dependent on the practice context and on social learning processes, and suggests how research knowledge uptake might be supported from this vantage point.

RESUMO

INTRODUCTION: Determining the extent of residual disease in the breast and axilla following neoadjuvant chemotherapy (NACT) is vital for surgical planning. Traditionally patients with incomplete radiological response in the breast after NACT undergo axillary node clearance, regardless of axillary clinical and radiological response. The aim of this study was to determine whether radiological and/or pathological response in the breast to NACT were predictive of axillary response. MATERIALS AND METHODS: A retrospective cohort study of patients with operable breast cancer with histologically proven axillary lymph node involvement who received NACT and underwent definitive surgical treatment between 1/1/2016 and 31/12/2018 were included. All had MRI and/or US of the breast and axilla before, mid-treatment and at the end of NACT. RESULTS: The 83 patients had a median age of 50 years (range 25-77). MRI had a positive predictive value (PPV) of 52.6% and negative predictive value (NPV) of 81.8% for breast pathological complete response (pCR). For axillary pCR, US had a PPV of 60.0% and NPV of 89.6%. Only 71% of patients had radiological concordance; 15.9% had radiological complete response (rCR) in breast and axilla whilst 55.1% had neither breast nor axillary rCR. 85.6% of patients had pathological concordance (20.5% with breast and axillary pCR: 65.1% with residual disease in both). CONCLUSION: Radiological and pathological response in the breast to NACT does not accurately predict axillary response. The axilla and the breast should be viewed and assessed as two separate entities for treatment plans.

RESUMO

BACKGROUND: Increasingly, health researchers must demonstrate the impact and real-life applications of their research. We investigated how health researchers with expertise in knowledge translation report research translation activities and impact on their curriculum vitae (CV). METHODS: We conducted a cross-sectional survey of health researchers with expertise in knowledge translation as we anticipated best practices in CV reporting from this specialized group. Our survey asked participants about their reporting of research translation and impact activities on their CVs, intention to report, and barriers and facilitators to reporting such activities on their CVs. We calculated univariate descriptive statistics for all quantitative data. Linear regression models determined predictors of researchers' intention to report research translation and impact activities on their CVs. We analyzed open-ended qualitative responses using content analysis. RESULTS: One hundred and fifty-three health researchers responded to the survey (response rate = 29%). Most respondents were Canadian, were female, and had a doctoral degree. Eighty-two percent indicated they reported at least one research translation and/or impact indicator on their CVs. Of those, health researchers commonly reported the following: advisory/regulatory committee membership related to research program (83%), research translation award(s) (61%), and academic performance assessments (59%). Researchers least commonly indicated the following: citation metric scores (31%), summaries of impact (21%), and requests to use research materials and/or products (19%). Fewer than half of the health researchers intended to report knowledge translation (43%) and impact (33%) on their CVs. Strong beliefs about capabilities and consequences of reporting research translation and/or impact were significant predictors of intention. Main barriers were as follows: CV templates do not include research translation and impact activities, participants perceived employers do not value research translation and impact activities, and lack of metrics to evaluate research translation and impact. Ninety-six percent were unaware of a CV template formatted to include research translation and/or impact reporting. CONCLUSIONS: Knowledge translation and impact indicators on the CV are inconsistently reported by our sample of health researchers. Modifiable barriers should be addressed to support more consistent reporting of such activities, including providing a CV template that includes research translation and impact as well as clear metrics to quantify them.

RESUMO

Studies from around the world have shown that hospital-acquired infections increase the costs of medical care, morbidity and mortality. The aim of this study was to determine cost and attributable mortality associated with hospital-acquired bacteraemia in a tertiary care centre in India. This was a retrospective case-control, cost utility analysis set in the cardiothoracic unit of a 200-bedded tertiary care cardiac hospital. Cases included adult patients who underwent coronary artery bypass graft and/or valve replacement surgery who developed bacteraemia (indicated by positive blood cultures) during postoperative stay (N=24). Controls were age- and sex-matched adult patients who underwent similar procedures but who did not develop bacteraemia (N=48). Data were collected from patient medical records and other administrative databases for cost analysis. Prolongation of hospital stay, attributable mortality and extra costs associated with hospital-acquired bacteraemia were analysed. Statistical analysis was done using Fisher's exact test and unpaired t-test. Patients with hospital-acquired bacteraemia experienced a significantly longer total hospital stay [mean: 22.9 days; 95% confidence interval (CI): 17.2-28.6; P<0.0001], significantly longer ICU stay (mean: 11.3 days; 95% CI: 9.0-13.6; P<0.0001), a significantly higher mortality (mean: 54%; P<0.0001) and cost significantly more (mean: US $14,818; 95% CI: 10,663-18,974; P<0.0001) than controls. We conclude that hospital-acquired bacteraemia significantly increases mortality and costs of hospitalisation in lower income developing countries. Our study demonstrates that costs associated with HAIs are similar between developing and developed countries. Better infection control planning and infrastructure may offset some of these costs.

RESUMO

The role of fathers prior to conception, during pregnancy, and in the post-partum period has generally not been a key consideration for Obstetric Physicians. However, this view may need challenging. This paper outlines the key importance of fathers in all phases of obstetric medical care. We review the contribution of paternal factors such as genetics, health, and lifestyle to fetal development, pregnancy complications, and maternal and neonatal wellbeing. The role of fathers in complex care decisions during pregnancy is also reviewed. Postpartum, fathers have a substantial role in shaping the future of the family unit through encouraging breastfeeding and creating a supportive environment for motherhood. This review proposes areas for future research and recommends an evidence-based change in practice in obstetric medicine that focuses on recognizing the role of fathers in the pregnancy journey.

RESUMO

PURPOSE: The ability to monitor and study developmental dysplasia of the hip (DDH) requires validated radiographic outcome measures. The sourcil method of acetabular index measurement (AI-S) has not yet been shown to be a reliable measure of acetabular dysplasia in a DDH population, despite its widespread use. The aims of this study were to test the reliability of the AI-S method in a DDH population, and to compare the reliability of the AI-S method with that of the classic lateral edge method (AI-L). METHODS: From an institutional database, standardized anteroposterior hip radiographs were obtained from a cohort of 35 female patients (70 hips) at two and five years of age who had been treated nonoperatively for DDH. Three observers independently measured the acetabular index using the AI-L and AI-S methods on all 70 hips at two time points, four weeks apart. RESULTS: The inter-rater reliability intraclass correlation coefficient (ICC) for the AI-L and AI-S methods was between good and excellent at 0.94 (confidence interval (CI) 0.89 to 0.96) and 0.91 (CI 0.87 to 0.94), respectively. The ICCs for intra-rater reliability for the AI-L method were excellent at 0.93 (CI 0.90 to 0.95), 0.95 (CI 0.93 to 0.97) and 0.95 (CI 0.94 to 0.97) for raters 1, 2 and 3, respectively. The ICCs for intra-rater reliability for the AI-S method were between good and excellent at 0.91 (CI 0.87 to 0.93), 0.93 (CI 0.90 to 0.95) and 0.90 (CI 0.86 to 0.93) for raters 1, 2 and 3 respectively. CONCLUSION: Both AI-S and AI-L methods are equally reliable radiographic measures of DDH. LEVEL OF EVIDENCE: Level III (diagnostic).

RESUMO

PURPOSE: The purpose of the present study was to determine the relatedness of Staphylococcus aureus strains successively isolated over a 7-day period from a single bacteraemic patient undergoing antibiotic treatment with vancomycin. METHODS: The S. aureus strains had been isolated and sequenced previously. Antibiotic susceptibility testing, population analysis profiling, and lysostaphin sensitivity and phagocytic killing assays were used to characterize these clonal isolates. RESULTS: The seven isolates (MEH1-MEH7) were determined to belong to a common multilocus sequence type (MLST) and spa type. Within the third and fifth day of vancomycin treatment, mutations were observed in the vraS and rpsU genes, respectively. Population analysis profiles revealed that the initial isolate (MEH1) was vancomycin-susceptible S. aureus (VSSA), while those isolated on day 7 were mostly heteroresistant vancomycin-intermediate S. aureus (hVISA). Supporting these findings, MEH7 was also observed to be slower in growth, to have an increase in cell wall width and to have reduced sensitivity to lysostaphin, all characteristics of VISA and hVISA strains. In addition, MEH7, although phagocytosed at numbers comparable to the initial isolate, MEH1, survived in higher numbers in RAW 264.7 macrophages. Macrophages infected with MEH7 also released more TNF-α and IFN-1ß. CONCLUSION: We report an increasing resistance to vancomycin coupled with daptomycin that occurred within approximately 3 days of receiving vancomycin and steadily increased until the infection was cleared with an alternative antibiotic therapy. This study reiterates the need for rapid, efficient and accurate detection of hVISA and VISA infections, especially in high-bacterial load, metastatic infections like bacteraemia.

RESUMO

BACKGROUND: The complicated natural history of venous ulcers requires the continued development and improvement of treatments to ensure the most effective management. Compression therapy or surgical correction of superficial venous incompetence (SVI) are currently the main methods employed for the treatment for venous ulceration (VU). This review compares and summates the healing and recurrence rates for each treatment modality used over the last thirty years. METHODS: Sixty-one articles investigating compression and superficial venous surgical treatments were obtained from a systematic search of electronic databases (Medline, Embase, The Cochrane Library, and Google Scholar) and then an expanded reference list review. Patient demographics, CEAP classification, patterns of venous insufficiency, type of intervention, length of follow up, healing and recurrence rates for venous ulceration was assessed. Inadequate data in seven reports led to their exclusion. Recent randomised controlled trials (RCTs) specifically comparing superficial surgery to compression therapy were reviewed and data from non-randomised and/or 'small' clinical studies prior to 2000 underwent summation analysis. RESULTS: Five RCTs since 2000 demonstrate a similar healing rate of VU with surgery and conservative compression treatments, but a reduction in ulcer recurrence rate with surgery. The effect of deep venous incompetence (DVI) on the ulcer healing is unclear, but sub-group analysis of long-term data from the ESCHAR trial suggests that although surgery results in a less impressive reduction in ulcer recurrence in patients with DVI, these patients appear to still benefit from surgery due to the haemodynamic and clinical benefits that result. The RCTs also highlight that a significant proportion of VU patients are unsuitable for surgical treatment. Summation of data from earlier studies (before 2000), included twenty-one studies employing conservative compression alone resulted in an overall healing rate of 65% (range 34-95%) and ulcer recurrence of 33% (range 0-100%). In thirty-one studies investigating superficial venous surgery, the overall rate of ulcer healing was 81% (range 40-100%) with a post-operative recurrence rate of 15% (range 0-55%). The duration of follow up care in the surgical studies was approximately twice as long as in the conservative studies, which would lend to more reliable recurrence data. CONCLUSIONS: Evidence from the current literature, would suggest that superficial venous surgery is associated with similar rates of ulcer healing to compression alone, but with less recurrence. The effects of post-operative compression and DVI on the efficacy of surgery are still unclear.

RESUMO

There is considerable uncertainty about the management of hypothyroidism in pregnancy. Our aim was to establish the pattern of thyroxine dose adjustment needed and to determine the clinical reasons for these changes and the contributory factors. Of 89 pregnancies, thyroxine dose was unchanged in 50, increased (by a mean of 38 micrograms) in 34, and decreased in 5. Twenty-three percent of women who were tested in the first trimester needed an immediate increase in thyroxine. One-quarter (26%) of the women who needed a gestational increase in thyroxine dose had had a recent pre-pregnancy increase in thyroxine requirement (compared with 0% in women on static dose in pregnancy, P < 0.001). Furthermore, they did not require a decrease in thyroxine dose postpartum, suggesting a long-term need for more thyroxine rather than a transient gestational effect. None of the women who had stable doses of thyroxine during pregnancy had required recent pre-pregnancy changes in dose or needed postnatal changes. Inadequate pre-pregnancy control of thyroid function is associated with a need to increase thyroxine dosage during pregnancy.

RESUMO

PURPOSE: With the escalating cost of healthcare provision, surgical techniques that could lead to shorter postoperative stay and reducing cost of health provision are welcomed. We report the results of a prospective randomized trial to investigate the role of harmonic scalpel (HS) in reducing postsurgical seroma formation, complications, pain and consequent cost in breast surgery. PATIENTS AND METHODS: Thirty-three procedures were carried out on 32 women. Patients were prospectively randomized to either HS or electrocautery (EC). The two cohorts were accordingly matched and postsurgical seroma volumes, complications and pain scores were documented. RESULTS: There were 16 procedures in the HS and 17 in the EC group. First 48 h drainage, total drained volume, aspirated volume, operative time, pain score, number of patients that developed seromas, number of clinic visits for aspiration, complications and required analgesia were comparable in the two groups. Multivariate analysis showed no significant correlation between the total amount of seroma drainage and the known risk factors (body mass index/BMI, size of the invasive tumor and number of positive nodes). CONCLUSION: No significant reduction in seroma formation or wound complications and pain could be found with the use of HS. We were unable to demonstrate any significant clinical advantages with the use of HS or cost benefit.

RESUMO

OBJECTIVE: The main goal of oncoplastic breast surgery (OBS) is to optimize cosmetic outcomes and reduce patient morbidity, while still providing an oncologically-safe surgical outcome and extending the target population of conservative surgery. Although the growing number of reported experiences with oncoplastic surgery, few studies account for the long-term outcomes. PATIENTS AND METHODS: Between January 2000 and December 2010, 1024 consecutive oncoplastic surgeries were performed and prospectively included in a database. Demographic data, histological and oncological evaluation and surgical complications were recorded. The role of tumor and patients' characteristics on the development of local recurrence and metastases were assessed by multivariate analysis. RESULTS: Median follow up was 74.2 months. The average age of patients was 56.24. In 869 patients (84.9%) an invasive tumor and in 155 (15.1%) an in situ tumor (11% DCIS and 4% LIN) was found. The average size of the tumor was 24.5 mm. A positive margin presented in 67 (6.5%) patients. Forty patients (50%) underwent re-excision and 39 (49.4%) underwent mastectomy. The overall breast conservation rate was 96.2%. Reported complications were: 17 wound infections (1.7%); 106 hematomas (10.4%); 94 lymphorrheas (9.2%), 48 partial wound dehiscence (4.7%). Local recurrences (LR) were observed in 49 patients (4.7%). The risk of local recurrence was significantly higher in the group of patients with lymphovascular invasion and with high grade (G) (p < 0.05). 52 (5.07%) distant metastases were reported and the related risk was significantly higher in the group of patients with lymphovascular invasion and with negative receptors (p < 0.05). CONCLUSIONS: Oncoplastic surgery provides an acceptable oncological long-term outcome and can be used to treat with conservative surgery also a selected population of patients who would had otherwise undergone mastectomy in the past.
