RESUMO

Measuring and benchmarking quality of care in surgical oncology has been gaining popularity. In autologous breast reconstruction (ABR), a standardized set of indicators to assess quality of care is lacking. In this study, we defined a set of evidence-based quality indicators for autologous breast reconstruction. First, we performed a systematic review to identify factors related to quality of care in ABR. Variables were categorized depending on their function: indicators related to outcome, indicators related to process and case-mix variables. The review was followed by a 3-round Delphi Consensus to determine which indicators and case-mix-variables were considered relevant and feasible for inclusion in an ABR standard set of indicators. 932 unique articles were identified, of which 110 papers were included in the study. Indicators were categorized by function: outcome, process and case-mix variables. In total, 8 process indicators and 41 outcome indicators were extracted. 30 case-mix-variables were included. Following 3 rounds of questioning in the Delphi Consensus, all respondents agreed on type of ABR, oncological outcomes and patient satisfaction for the standard set. Indicators related to complications were consistently ranked highly. Most process indicators were not chosen after 3 rounds of questioning. 11 case-mix-variables were included in the final set. Following the Delphi Consensus, it was possible to identify 33 process and outcome indicators and 11 case-mix-variables for inclusion for a standard set of quality indicators. With the inclusion of both objective and patient-reported outcome measures, this set of indicators provides a multidimensional measurement tool for quality assessment for ABR.

RESUMO

Increased exposure to ultraviolet radiation (UVR) is associated with an increased risk of nonmelanoma skin cancer. Cutaneous surgery can be negatively influenced by UVR, causing delayed wound healing, hyperpigmentation of the scar, and an increased incidence of additional skin cancers. By changing sun protection behavior, these risks can be limited. Therefore, this study evaluates changes in patients' sun protective behavior after Mohs micrographic surgery (MMS). Patients undergoing MMS between December 2017 and November 2019 were included. Patients were asked to complete the FACE-Q Skin Cancer - Sun Protection Behavior checklist before and 3 months and 1 year post-surgery. A total of 125 patients completed the pre-operative and 3-months post-operative checklists, and 89 (71.2%) completed the 1-year post-operative checklist. Reported sun protective behaviors increased post-surgery at all time points (p < 0.001). Patients with a prior history of facial skin cancer demonstrated a larger increase in sun protection behaviors after surgery than patients without a history of facial skin cancer (p = 0.04). Patients with defects located on the ear or scalp demonstrated a lesser increase in sun protection behaviors than patients with defects located in more conspicuous areas as the face (p = 0.02). Our study demonstrates a change in sun protection behavior, with an increase in sun protection behavior over time in patients after MMS. However, more improvement is possible. Targeted counseling can increase sun protection behavior in patients without a history of facial skin cancer and patients with skin cancer located on the ears or scalp.

RESUMO

Implanted porous precision templated scaffolds (PTS) with 40-µm spherical pores reduce inflammation and foreign body reaction (FBR) while increasing vascular density upon implantation. Larger or smaller pores, however, promote chronic inflammation and FBR. While macrophage (MØ) recruitment and polarization participates in perpetuating this pore-size-mediated phenomenon, the driving mechanism of this unique pro-healing response is poorly characterized. We hypothesized that the primarily myeloid PTS resident cells release small extracellular vesicles (sEVs) that induce pore-size-dependent pro-healing effects in surrounding T cells. Upon profiling resident immune cells and their sEVs from explanted 40-µm- (pro-healing) and 100-µm-pore diameter (inflammatory) PTS, we found that PTS pore size did not affect PTS resident immune cell population ratios or the proportion of myeloid sEVs generated from explanted PTS. However, quantitative transcriptomic assessment indicated cell and sEV phenotype were pore size dependent. In vitro experiments demonstrated the ability of PTS cell-derived sEVs to stimulate T cells transcriptionally and proliferatively. Specifically, sEVs isolated from cells inhabiting explanted 100 µm PTS significantly upregulated Th1 inflammatory gene expression in immortalized T cells. sEVs isolated from cell inhabiting both 40- and 100-µm PTS upregulated essential Treg transcriptional markers in both primary and immortalized T cells. Finally, we investigated the effects of Treg depletion on explanted PTS resident cells. FoxP3+ cell depletion suggests Tregs play a unique role in balancing T cell subset ratios, thus driving host response in 40-µm PTS. These results indicate that predominantly 40-µm PTS myeloid cell-derived sEVs affect T cells through a distinct, pore-size-mediated modality.

RESUMO

BACKGROUND: Nipple-sparing mastectomy (NSM) is being performed increasingly for risk reduction in high-risk groups. There are limited data regarding complications and oncological outcomes in women undergoing bilateral prophylactic NSM. This study reviewed institutional experience with prophylactic NSM, and examined the indications, rates of postoperative complications, incidence of occult malignant disease and subsequent breast cancer diagnosis. METHODS: Women who had bilateral prophylactic NSM between 2000 and 2016 were identified from a prospectively maintained database. Rates of postoperative complications, incidental breast cancer, recurrence and overall survival were evaluated. RESULTS: A total of 192 women underwent 384 prophylactic NSMs. Indications included BRCA1 or BRCA2 mutations in 117 patients (60·9 per cent), family history of breast cancer in 35 (18·2 per cent), lobular carcinoma in situ in 29 (15·1 per cent) and other reasons in 11 (5·7 per cent). Immediate breast reconstruction was performed in 191 patients. Of 384 NSMs, 116 breasts (30·2 per cent) had some evidence of skin necrosis at follow-up, which resolved spontaneously in most; only 24 breasts (6·3 per cent) required debridement. Overall, there was at least one complication in 129 breasts (33·6 per cent); 3·6 and 1·6 per cent had incidental findings of ductal carcinoma in situ and invasive breast cancer respectively. The nipple-areola complex was preserved entirely in 378 mastectomies. After a median follow-up of 36·8 months, there had been no deaths and no new breast cancer diagnoses. CONCLUSION: These findings support the use of prophylactic NSM in high-risk patients. The nipples could be preserved in the majority of patients, postoperative complication rates were low, and, with limited follow-up, there were no new breast cancers.


ANTECEDENTES: La mastectomía con preservación del pezón (nipple-sparing mastectomy, NSM) se realiza cada vez más para reducir riesgos en los grupos de pacientes de alto riesgo. Se dispone de pocos datos sobre complicaciones y resultados oncológicos en mujeres sometidas a NSM bilateral profiláctica. Este estudio revisó la experiencia institucional de la NSM profiláctica, y analizó las indicaciones, tasas de complicaciones postoperatorias, incidencia de enfermedad maligna oculta y diagnóstico de subsiguiente cáncer de mama. MÉTODOS: Se identificaron mujeres sometidas a NSM bilateral profiláctica durante el periodo 2000-2016 a partir de una base de datos prospectiva. Se evaluaron tasas de complicaciones postoperatorias, cáncer de mama incidental, recidiva y supervivencia global. RESULTADOS: Un total de 192 mujeres fueron sometidas a 384 NSMs profilácticas. Las indicaciones incluyeron mutaciones BRCA1 o BRCA2 en 117 (61%) pacientes, historia familiar de cáncer de mama en 35 (18%), carcinoma lobulillar in situ en 29 (15%) y otros motivos en 11 (5,7%). La reconstrucción mamaria inmediata se realizó en 191 pacientes. De las 384 NSMs, 116 (30%) presentaron alguna evidencia de necrosis de la piel durante el seguimiento y la mayoría se resolvieron de forma espontánea, con solo 24 (6,2%) mamas que requirieron desbridamiento. Globalmente hubo al menos una complicación en 129 (34%) mamas; 3,6% y 1,6% tuvieron hallazgos incidentales de carcinoma ductal in situ o cáncer de mama invasivo, respectivamente. El complejo areola-pezón se preservó completamente en 378 mastectomías. Tras una mediana de seguimiento de 36,8 meses, no hubo fallecimientos ni ningún diagnóstico nuevo de cáncer de mama. CONCLUSIÓN: Estos hallazgos apoyan la utilización de la NSM profiláctica en pacientes de alto riesgo. En la mayoría pacientes fue posible la preservación del pezón, las tasas de complicaciones postoperatorias fueron bajas y, con un seguimiento limitado, no hubo nuevos casos de cáncer de mama.

RESUMO

BACKGROUND: Effects of postmastectomy radiotherapy (PMRT) on autologous breast reconstruction (BRR) are controversial regarding surgical complications, cosmetic appearance and quality of life (QOL). This systematic review evaluated these outcomes after abdominal free flap reconstruction in patients undergoing postoperative adjuvant radiotherapy (PMRT), preoperative radiotherapy (neoadjuvant radiotherapy) and no radiotherapy, aiming to establish evidence-based optimal timings for radiotherapy and BRR to guide contemporary management. METHODS: The study was registered on PROSPERO (CRD42017077945). Embase, MEDLINE, Google Scholar, CENTRAL, Science Citation Index and ClinicalTrials.gov were searched (January 2000 to August 2018). Study quality and risk of bias were assessed using GRADE and Cochrane's ROBINS-I respectively. RESULTS: Some 12 studies were identified, involving 1756 patients (350 PMRT, 683 no radiotherapy and 723 neoadjuvant radiotherapy), with a mean follow-up of 27·1 (range 12·0-54·0) months for those having PMRT, 16·8 (1·0-50·3) months for neoadjuvant radiotherapy, and 18·3 (1·0-48·7) months for no radiotherapy. Three prospective and nine retrospective cohorts were included. There were no randomized studies. Five comparative radiotherapy studies evaluated PMRT and four assessed neoadjuvant radiotherapy. Studies were of low quality, with moderate to serious risk of bias. Severe complications were similar between the groups: PMRT versus no radiotherapy (92 versus 141 patients respectively; odds ratio (OR) 2·35, 95 per cent c.i. 0·63 to 8·81, P = 0·200); neoadjuvant radiotherapy versus no radiotherapy (180 versus 392 patients; OR 1·24, 0·76 to 2·04, P = 0·390); and combined PMRT plus neoadjuvant radiotherapy versus no radiotherapy (272 versus 453 patients; OR 1·38, 0·83 to 2·32, P = 0·220). QOL and cosmetic studies used inconsistent methodologies. CONCLUSION: Evidence is conflicting and study quality was poor, limiting recommendations for the timing of autologous BRR and radiotherapy. The impact of PMRT and neoadjuvant radiotherapy appeared to be similar.


ANTECEDENTES: En pacientes sometidas a una reconstrucción mamaria (breast reconstruction, BRR) con tejido autólogo se discuten los efectos de la radioterapia post-mastectomía (post-mastectomy radiotherapy, PMRT) en las complicaciones quirúrgicas, el resultado estético y la calidad de vida (quality of life, QOL). Esta revisión sistemática evaluó dichos resultados tras una reconstrucción mamaria con un colgajo libre abdominal en pacientes tratadas con PMRT, radioterapia preoperatoria (Neo RT) y sin radioterapia (RT), a fin de establecer los momentos óptimos de la RT y BRR basados en la evidencia, como guía del tratamiento actual. MÉTODOS: El estudio se registró en la base de datos PROSPERO (CRD42017077945). Se realizaron búsquedas en Embase, MEDLINE, Google Scholar, CENTRAL, Science Citation Index y Clinicaltrials.gov (enero de 2000-agosto de 2018). La calidad de los estudios y el riesgo de sesgo se evaluaron mediante las herramientas GRADE y ROBINS-I de la Cochrane, respectivamente. RESULTADOS: Se identificaron 12 estudios que incluían 1.756 pacientes (350 PMRT, 683 sin RT y 723 Neo RT), con una mediana de seguimiento de 27,1 meses (rango 12,0-54,0) para PMRT, 16,8 meses (1,0-50,3) para Neo RT y 18,3 meses (1,0-48,7) para sin RT. Se incluyeron tres cohortes prospectivas y nueve retrospectivas. No hubo estudios aleatorizados. Los estudios comparativos de RT evaluaron la PMRT (n = 5) y la Neo RT (n = 4). Todos los estudios fueron de baja calidad, con riesgos de sesgo de moderados a graves. Las complicaciones graves fueron similares entre los grupos: PMRT (n = 92) versus sin RT (n = 141), razón de oportunidades (odds ratio, OR) 2,35, i.c. del 95% 0,63-8,81), P = 0,200; Neo RT (n = 180) versus no RT (n = 392) (OR 1,24, i.c. del 95% 0,76-2,04), P = 0,390; o RT combinada (PMRT y neoadyuvante) (n = 272) versus no RT (n = 453) (OR 1,38, i.c. del 95% 0,83-2,32), P = 0,220. Los estudios de calidad de vida y de resultados estéticos utilizaron metodologías poco consistentes. CONCLUSIÓN: La evidencia es contradictoria y la calidad de los estudios muy pobre, hechos que limitan las posibles recomendaciones para el momento de la BRR con tejido autólogo y la RT. El impacto de la PMRT o la Neo RT parecen ser similares.

RESUMO

BACKGROUND: Conflicting evidence challenges clinical decision-making when breast reconstruction is considered in the context of radiotherapy. Current literature was evaluated and key statements on topical issues were generated and discussed by an expert panel at the International Oncoplastic Breast Surgery Meeting in Milan 2017. METHODS: Studies on radiotherapy and breast reconstruction (1985 to September 2017) were screened using MEDLINE, Embase and CENTRAL. The literature review yielded 30 controversial key questions. A set of key statements was derived and the highest levels of clinical evidence (LoE) for each of these were summarized. Nineteen panellists convened for dedicated discussions at the International Oncoplastic Breast Surgery Meeting to express agreement, disagreement or abstention for the generated key statements. RESULTS: The literature review identified 1522 peer-reviewed publications. A list of 22 key statements was produced, with the highest LoE recorded for each statement. These ranged from II to IV, with most statements (11 of 22, 50 per cent) supported by LoE III. There was full consensus for nine (41 per cent) of the 22 key statements, and more than 75 per cent agreement was reached for half (11 of 22). CONCLUSION: Poor evidence exists on which to base patient-informed consent. Low-quality studies are conflicting with wide-ranging treatment options, precluding expert consensus regarding optimal type and timing of breast reconstruction in the context of radiotherapy. There is a need for high-quality evidence from prospective registries and randomized trials in this field.


ANTECEDENTES: El hecho de que la evidencia disponible sea conflictiva supone un reto para la toma de decisiones a la hora de considerar la reconstrucción mamaria en el contexto de radioterapia (radiotherapy, RT). En el seno de un panel de expertos reunidos durante el International Oncoplastic Breast Surgery Meeting celebrado en Milán en 2017, se revisó la literatura disponible y se generaron y discutieron los aspectos más relevantes. MÉTODOS: Se hizo una búsqueda bibliográfica de los estudios de RT y reconstrucción mamaria (1985-septiembre de 2017) en las bases MEDLINE, EMBASE y CENTRAL. La revisión de la literatura permitió identificar 30 cuestiones clave controvertidas. A partir de ellas, se construyeron una serie de afirmaciones, para las que se obtuvo el mayor nivel de evidencia (levels of clinical evidence, LoE) posible. El acuerdo, desacuerdo o abstención respecto a las cuestiones propuestas fueron el resultado de las discusiones de 19 expertos reunidos durante el International Oncoplastic Breast Surgery Meeting. RESULTADOS: Se identificaron 1.522 artículos publicados en revistas con peer review. Se elaboró una lista de 22 afirmaciones clave y se anotó el LoE más alto obtenido para cada una de ellas. El grado de variabilidad fue de II a IV, pero la mayoría de las afirmaciones (54,5%) obtuvieron un LoE III. Hubo un consenso total en el 41% (9/22) de las afirmaciones, mientras que se obtuvo más de un 75% de acuerdo en la mitad de las afirmaciones (11/22). CONCLUSIÓN: La evidencia en la que basar el consentimiento informado en estos pacientes es escasa. Se trata de estudios de baja calidad con gran variedad de opciones terapéuticas, que dificultan el consenso de los expertos acerca del tipo y momento óptimo para la reconstrucción mamaria en el contexto de RT. Para obtener datos de mayor calidad se precisan estudios prospectivos y ensayos clínicos en este campo.

RESUMO

BACKGROUND: Psychosocial concerns represent important outcomes in studies of treatments for acne and acne scarring. Also important, but largely overlooked, is the concept of appearance. OBJECTIVES: To design an acne-specific patient-reported outcome measure for acne and acne scarring. METHODS: We used a mixed-methods approach. Phase I involved 21 patient interviews that were audio-recorded, transcribed and coded. Concepts were identified and developed into scales that were refined through 10 cognitive interviews and input from 16 clinical experts. Phase II involved data collection at hospital and community-based dermatology clinics in Canada and the U.S.A. Eligible participants were aged 12 years and older with acne and/or acne scars on the face, chest and/or back. Rasch Measurement Theory (RMT) analyses were performed to examine psychometric properties. RESULTS: Phase I led to the development of seven scales that measure appearance of facial skin, acne (face, chest and back) and acne scars, acne-specific symptoms and appearance-related distress. In phase II, 256 patients completed the ACNE-Q. RMT analysis provided evidence that the items of each scale worked together conceptually and statistically. Most participants scored within the range of measurement for each scale (81·9-93·1%). Reliability was high, with person separation index values and Cronbach alpha values > 0·90 for the appearance scales, ≥ 0·87 for appearance-related distress and ≥ 0·75 for symptoms. Worse scores on appearance scales correlated with worse symptom scores and more appearance-related distress. CONCLUSIONS: The ACNE-Q is a rigorously developed instrument that can be used to measure appearance and other patient-centred concerns. What's already known about this topic? Acne is a common dermatological condition that can have an important impact on psychosocial function. Current patient-reported outcome measures specific to acne focus mostly on measuring psychological and social impact. What does this study add? The ACNE-Q provides a set of independently functioning scales that measure appearance of facial, back and chest acne, acne scarring and facial skin. Additional scales measure appearance-related distress and acne symptoms. What are the clinical implications of this work? ACNE-Q provides the dermatology community with a rigorously developed patient-reported measure for acne that can be applied in clinical trials, research and patient care. The measurement of appearance by ACNE-Q scales is more comprehensive than in other instruments providing important information on appearance of their acne and/or acne scars from the patient perspective.

RESUMO

BACKGROUND: The patient's perspective of their facial scar after skin cancer surgery influences perception of care and quality of life (QoL). Appearance satisfaction after surgery is also an important but often overlooked treatment outcome. OBJECTIVES: To report the psychometric validation of the FACE-Q Skin Cancer Module consisting of five scales, measuring appearance satisfaction (Satisfaction with Facial Appearance, Appraisal of Scars), QoL (Cancer Worry, Appearance-related Psychosocial Distress) and the patient experience (Satisfaction with Information: Appearance). METHODS: Participants underwent Mohs surgery for facial basal or squamous cell carcinoma or excision of early facial melanoma. Cohort 1 received a set of scales before and after surgery. Cohort 2 received the scales on two occasions in the postoperative period for test-retest reliability. Rasch measurement theory was used to select (item-reduce) the most clinically meaningful items for the scales. Reliability, validity, floor and ceiling effects and responsiveness were also analysed. RESULTS: Of 334 patients, 209 (response rate 62·6%) were included. Rasch analysis reduced the total scale items from 77 to 41. All items had ordered thresholds and good psychometric fit. Reliability was high (Person separation index and Cronbach's α ≥ 0·90) and scales measuring similar constructs were correlated. High floor and ceiling effects were seen for the scales. The Cancer Worry scale demonstrated responsiveness (P = 0·004). CONCLUSIONS: The FACE-Q Skin Cancer Module meet the requirements of the Rasch model providing linearized measurement. Discriminating between patients with minimal appearance or worry impairment may be a limitation. The scales can be used for larger validation studies, clinical practice and research.

RESUMO

BACKGROUND: Nipple-sparing mastectomy (NSM) is associated with improved cosmesis and is being performed increasingly. Its role in BRCA mutation carriers has not been well described. This was a study of the indications for, and outcomes of, NSM in BRCA mutation carriers. METHODS: BRCA mutation carriers who underwent NSM were identified. Details of patient demographics, surgical procedures, complications, and relevant disease stage and follow-up were recorded. RESULTS: A total of 177 NSMs were performed in 89 BRCA mutation carriers between September 2005 and December 2013. Twenty-six patients of median age 41 years had NSM for early-stage breast cancer and a contralateral prophylactic mastectomy. Mean tumour size was 1·4 (range 0·1-3·5) cm. Sixty-three patients of median age 39 years had prophylactic NSM, eight of whom had an incidental diagnosis of ductal carcinoma in situ. There were no local or regional recurrences in the 26 patients with breast cancer at a median follow-up of 28 (i.q.r. 15-43) months. There were no newly diagnosed breast cancers in the 63 patients undergoing prophylactic NSM at a median follow-up of 26 (11-42) months. All patients had immediate breast reconstruction. Five patients (6 per cent) required subsequent excision of the nipple-areola complex for oncological or other reasons. Skin desquamation occurred in 68 (38·4 per cent) of the 177 breasts, and most resolved without intervention. Debridement was required in 13 (7·3 per cent) of the 177 breasts, and tissue-expander or implant removal was necessary in six instances (3·4 per cent). CONCLUSION: NSM is an acceptable choice for patients with BRCA mutations, with no evidence of compromise to oncological safety at short-term follow-up. Complication rates were acceptable, and subsequent excision of the nipple-areola complex was rarely required.

RESUMO

In an effort to identify novel biallelically inactivated tumor suppressor genes (TSGs) in sporadic invasive and preinvasive non-small-cell lung cancer (NSCLC) genomes, we applied a comprehensive integrated multiple 'omics' approach to investigate patient-matched, paired NSCLC tumor and non-malignant parenchymal tissues. By surveying lung tumor genomes for genes concomitantly inactivated within individual tumors by multiple mechanisms, and by the frequency of disruption in tumors across multiple cohorts, we have identified a putative lung cancer TSG, Eyes Absent 4 (EYA4). EYA4 is frequently and concomitantly deleted, hypermethylated and underexpressed in multiple independent lung tumor data sets, in both major NSCLC subtypes and in the earliest stages of lung cancer. We found that decreased EYA4 expression is not only associated with poor survival in sporadic lung cancers but also that EYA4 single-nucleotide polymorphisms are associated with increased familial cancer risk, consistent with EYA4s proximity to the previously reported lung cancer susceptibility locus on 6q. Functionally, we found that EYA4 displays TSG-like properties with a role in modulating apoptosis and DNA repair. Cross-examination of EYA4 expression across multiple tumor types suggests a cell-type-specific tumorigenic role for EYA4, consistent with a tumor suppressor function in cancers of epithelial origin. This work shows a clear role for EYA4 as a putative TSG in NSCLC.

RESUMO

Pancreatic cancer is among the top five deadliest cancers in developed countries. Better knowledge of the molecular mechanisms contributing to its tumorigenesis is imperative to improve patient prognosis. Identification of novel tumor suppressor genes (TSGs) in pancreatic cancer will reveal new mechanisms of pathway deregulation and will ultimately help improve our understanding of this aggressive disease. According to Knudson's two-hit model, TSGs are classically disrupted by two concerted genetic events. In this study, we combined DNA methylation profiling with copy number and mRNA expression profiling to identify novel TSGs in a set of 20 pancreatic cancer cell lines. These data sets were integrated for each of ∼12 000 genes in each cell line enabling the elucidation of those genes that undergo DNA hypermethylation, copy-number loss and mRNA downregulation simultaneously in multiple cell lines. Using this integrative genomics strategy, we identified SOX15 (sex determining region Y-box 15) as a candidate TSG in pancreatic cancer. Expression of SOX15 in pancreatic cancer cell lines with undetectable expression resulted in reduced viability of cancer cells both in vitro and in vivo demonstrating its tumor suppressive capability. We also found reduced expression, homozygous deletion and aberrant DNA methylation of SOX15 in clinical pancreatic tumor data sets. Furthermore, we deduced a novel role for SOX15 in suppressing the Wnt/ß-catenin signaling pathway, which we hypothesize is a pathway through which SOX15 may exert its tumor suppressive effects in pancreatic cancer.

RESUMO

BACKGROUND: As survival rates increase, many people have to adjust to life after cancer. This includes adjusting to life after surgery. While previous research suggests that patients commonly strive to be 'normal' after mastectomy and reconstructive surgery, research surrounding individual perceptions of normality is lacking. AIM: The aim of this study was to explore concepts of normality within a sample of breast cancer patients eligible for reconstructive surgery following mastectomy. METHODS: A total of 35 semi structured interviews, with women who had undergone or were about to undergo breast reconstructive surgery following breast cancer, were analysed using thematic analysis. RESULTS: Four main themes emerged from the data. Women referred to looking normal (appearance); being able to fulfil everyday activities (behaviour); adapting to a new normal (reconstructing normality); and not being ill (health). The importance placed on each area of normality differed between patients. Additionally, patients used different standards to anchor concepts of normality. These included individual standards, social standards and clinical standards. DISCUSSION: The results indicate that although there are commonalities between patients' concepts of normality, it is important for health care professionals to recognise potential individual differences. This may usefully aid communication and help to manage expectations among patients considering surgical options.

RESUMO

PURPOSE/BACKGROUND: Excellent aesthetic outcomes have been demonstrated with TRAM flap breast reconstruction. However, abdominal wall morbidity after TRAM flap breast reconstruction has not been accurately evaluated in terms of patient symptoms or patient quality of life. To further examine this issue, we performed a cross-sectional survey of TRAM flap breast reconstruction patients utilising questions from a patient-related outcome measure questionnaire. PATIENTS AND METHOD: The questions were posed to post-mastectomy breast reconstruction patients. Items pertaining to abdominal wall symptoms and satisfaction with the outcome were reported on a 5-point Linkert Scale (1=very satisfied/no symptoms to 5=very dissatisfied/frequent symptoms). RESULTS: The study population consisted of 270 patients who underwent pedicled (n=183) or free (n=87) TRAM flap procedures. The frequency of abdominal wall symptoms reported on abdomen-specific questionnaire items was increased in the pedicled TRAM group relative to the free TRAM group. This included "tightness or pulling in abdomen" (2.34 vs. 2.01); "abdominal pain, bloating, or discomfort" (2.11 vs. 1.69); "difficulty doing everyday activities requiring the use of your abdominal muscles" (2.11 vs. 1.67); and "abdominal weakness" (2.36 vs. 1.8). CONCLUSION: We found a relatively low frequency of abdominal symptoms in the TRAM flap patients as a whole. However, there was a tendency towards increased abdominal symptoms in the pedicled TRAM patients compared to the free TRAM patients. As the population sizes in this study are somewhat limited, future studies with increased patient numbers may find greater differences between pedicled and free TRAM patients. In addition, studies evaluating the patients' abdominal wall symptoms pre- and postoperatively may allow for a detailed analysis of abdominal wall morbidity in post-mastectomy TRAM patients.

RESUMO

The purpose of this study was to review the authors' 13-year experience with free tissue transfer for head and neck oncology patients. This study was a retrospective review of 728 free flaps performed in 698 patients. Recipient sites were subdivided by region into the mandible (N = 253), mid face/orbit (N = 190), hypopharynx (N = 134), oral cavity (N = 104), skull base (N = 36), and scalp (N = 11). The overall free flap success rate was 98.6%. Seventy-nine flaps (10.9%) were reexplored for vascular compromise. Ten flaps (1.4%) were lost in their entirety. The overall complication rate was 17.5%. Four donor sites (forearm, fibula, rectus, and jejunum) were used for 92% of the patients. The results of the study confirm the efficacy of free tissue transfer in the reconstruction of oncological head and neck defects. In this series the free forearm, fibula, rectus, and jejunum flaps have become the workhorse donor sites for the vast majority of defects.

RESUMO

To evaluate the practice patterns of general and plastic surgeons regarding patients with early-stage breast cancer, all general and plastic surgeons in Quebec and Maryland were mailed self-administered questionnaires evaluating surgeon demographics, practice patterns, treatment preferences, and satisfaction with the results of lumpectomy and radiation therapy or breast reconstruction. Response rates of 38.3 percent and 26.7 percent were obtained for general surgeons in Quebec and Maryland, respectively. The ratio of reported mastectomies to lumpectomies was 1:2 in Maryland and 1:5 in Quebec. All general surgeons considered lumpectomy an important option. Ninety percent of Maryland surgeons versus 44 percent of Quebec surgeons considered mastectomy important. A total of 53.6 percent versus 24.9 percent of general surgeons in Maryland and Quebec, respectively, considered delayed reconstruction an important option. Additionally, 81.3 percent of Maryland surgeons considered immediate reconstruction important, and 79.6 percent discussed it with all stage I or II patients. More than 75 percent of Quebec general surgeons reported discussing immediate or delayed reconstruction with < or =50 percent of these women. Response rates of 53.6 percent and 48.8 percent were obtained for plastic surgeons in Quebec and Maryland, respectively. In one year Quebec plastic surgeons reported that they performed less than half the number of reconstructions performed by Maryland plastic surgeons (7.2 versus 17.3). In Quebec, 82.3 percent of surgeons reported that they frequently discuss delayed reconstruction, 25.1 percent immediate, 62.5 percent pedicled TRAM, and 51.7 percent nonautogenous options. In Maryland, 74.3 percent of plastic surgeons frequently discuss delayed reconstruction, 95.7 percent immediate, 89.9 percent pedicled TRAM, and 85.9 percent nonautogenous options. For women with early-stage breast cancer, regional variations exist in the surgical options discussed and provided.

RESUMO

Patients with early-stage breast cancer have three surgical options: lumpectomy with radiotherapy, mastectomy alone, and mastectomy with breast reconstruction. Our objective was to compare women in these three groups with respect to demographics, preoperative counseling, postoperative body image, and quality of life. Women having undergone surgery for stage 1 or 2 breast cancer between 1990 and 1995 were selected by random sampling of hospital tumor registries and were mailed a self-administered questionnaire, which included the Medical Outcomes Survey Short Form 36. Patients were stratified into three mutually exclusive groups: lumpectomy with axillary node dissection and radiotherapy, modified radical mastectomy, and modified radical mastectomy with breast reconstruction. In total, 267 of 525 surveys were returned (50.9 percent). Compared with mastectomy patients, breast reconstruction patients were younger (p < 0.001), better educated (p = 0.001), and more likely Caucasian (p = 0.02). Among mastectomy patients, 54.9 percent recalled that lumpectomy had been discussed preoperatively and 39.7 percent recalled discussion of breast reconstruction. Post-operative comfort with appearance was significantly lower for mastectomy patients. The relationship between type of surgery and postoperative quality of life varied with age. Under 55, quality of life was lowest for mastectomy patients on all but two Medical Outcomes Survey Short Form 36 subscales. Over 55, quality of life was lowest for lumpectomy patients on all subscales (p < 0.05 for all subscales except social functioning and role-emotional). Treatment choice may be related to age, race, education, and preoperative counseling. Whereas the effect of breast cancer on a woman's life is complex and individual, the type of surgery performed is a significant variable, whose impact may be related to patient age.

RESUMO

The experience with high-risk congenital diaphragmatic hernia (CDH) at an institution that does not offer extracorporeal membrane oxygenation (ECMO) was reviewed. Between January 1, 1983 and December 31, 1993, 38 children presented with Bochdalek-type CDH. Excluded were two infants with lethal cardiac anomalies and four presenting after 4 hours of age. Thus, the authors identified 32 high-risk patients. All had early respiratory distress and were intubated within 5 hours of birth. Sixteen were inborn; 16 were referred to the Izaak Walton Killam Children's Hospital (IWK) within 24 hours of birth. There were 19 males and 13 females. Three died before surgery could be attempted. Twenty-two survived, giving an overall survival rate of 69% (22 of 32). For 28 of the 32, the best preoperative postductal Pao2 (BPDPao2) was recorded. Fifteen of the 28 children had a BPDPao2 of greater than 100 mm Hg. Survival in this group was 14 of 15 (93%). Thirteen of the 28 patients had a BPDPao2 of less than 100 mm Hg. Survival in this group was 5 of 13 (38%). These survival rates are comparable to those of centers offering ECMO. BPDPao2 appears to be a useful discriminating variable.
