BACKGROUND Choosing which patients to recommend surgery for benign thyroid conditions can be difficult due to the subjective nature of compressive thyroid and hormonal symptoms. The aim of this prospective study was to analyse changes in quality of life (QOL) following thyroid surgery using a validated disease-specific assessment tool, the thyroid-related patient-reported outcome (ThyPRO) questionnaire. METHODS Participants undergoing elective thyroid surgery for benign conditions were recruited. Patient demographics and clinical data were collected. ThyPRO consists of 85 questions grouped into 13 physical, mental and social symptom domains. Patients completed a ThyPRO questionnaire pre-operatively and at 6 weeks and 6 months post-operatively. ThyPRO items were scored according to protocol to produce 13 subscales. Repeated measures linear models with no random effects were performed using data for each outcome. RESULTS Results were available for a total of 72 patients. The sample was predominately female (n = 63, 88%) with average age 49.8 years. The majority of patients underwent surgery for multi-nodular goitre. At 6 weeks post-operatively, significant improvement was demonstrated in the goitre, hypothyroid, hyperthyroid and anxiety symptom domains. At 6 months post-operatively, significant improvement was demonstrated in all but four domains. No domains demonstrated significant increase in impairment post-operatively. CONCLUSION Patients had significant improvement in nine of 13 symptom domains following surgery. Patients did not experience a negative impact on QOL following surgery. Further studies with larger patient cohorts may be able to identify potential pre-operative predictive factors for a post-operative improvement in QOL for benign thyroid disease.

BACKGROUND The size of thyroid nodules as measured by ultrasound (ultrasound size, USS) is routinely used in clinical decision-making. Reports of discrepancy between USS and pathological size (PS) evaluation have not analysed their systematic differences. The objective of this study was to uncover the lack of agreement (bias) between USS and PS measurements. METHODS A retrospective study was performed on 121 patients who had a total or hemi-thyroidectomy for a solitary nodule. Ordinary least product regression was used to detect and distinguish constant and proportional bias in unidimensional size measurements between USS and PS evaluation. Three-dimensional volume measurements were compared in a subgroup of 31 patients. Pre-specified acceptable limits of interchange were defined as 20% difference. RESULTS Ordinary least product regression demonstrated no constant or proportional bias between the two methods; regression equation: USS = (0.863) + (1.040) × PS. When nodules were grouped by size, discrepancies between the two methods were observed in nodules 10 mm but PS

Background Regionalization of care to specialized centers has improved outcomes for several cancer types. We sought to determine if treatment in a regional cancer center (RCC) impacts guideline adherence and outcomes for patients with melanoma. Methods In Alberta, Canada, 561 patients with stage I–IIIC primary melanoma were diagnosed between January 2009 and December 2010. The electronic health record was used to capture demographic and pathologic data. Provincial guidelines for sentinel lymph node biopsy (SLNB) and wide local excision (WLE) are based on recommendations of several pre-existing guidelines including the National Comprehensive Cancer Network. Results 148 of 561 patients were identified as having been treated at a RCC. Median follow-up was 45 months. Patients treated at the RCC presented with higher stage melanomas. The RCC was more likely to follow guideline recommendations for performing SLNB (81.3% vs. 55.4%, P

Background It is unclear if surgeons are performing comprehensive central neck dissections for well-differentiated thyroid cancer. The purpose of this study was to determine mean lymph node retrieval in central neck dissection as well as variability across surgeons and institutions. Methods A prospectively collected database identified 18 surgeons performing 425 central neck dissections, 313 unilateral and 112 bilateral. Demographics, perioperative, and pathologic factors were analyzed. Results Mean lymph node yield was 7.4 and 11.9 for unilateral and bilateral central neck dissection, respectively. Although 224 central neck dissections were prophylactic, both total and pathologic lymph node yields were significantly higher in therapeutic central neck dissection. There was a significant variation in lymph node yield across individual surgeons, institutions, and regions. High-volume central neck dissection surgeons have significantly lower lymph node yield compared to low-volume surgeons. Conclusion Central neck dissection seems to be performed adequately; however, there is a significant variation in lymph node yield. Future initiatives should try to standardize the central neck dissections performed, with emphasis on obtaining a sufficient yield. © 2015 Wiley Periodicals, Inc. Head Neck, 2015

Isolated limb infusion (ILI) delivers low-flow chemotherapy via percutaneous catheters to treat melanoma in-transit metastases.To describe the experience of two regional referral centres with ILI.A retrospective review of patients who underwent ILI between 2002 and 2012 was performed. Outcomes were measured using the WHO criteria for response, the Wieberdink toxicity score and long-term limb function using the Toronto Extremity Salvage Score (TESS).Fifty-two patients (mean age 66 years [range 27 to 90 years], female sex 65%, and lower [treated] limb in 86%) with 54 ILIs were reviewed. Wieberdink toxicity score was ≥3 in 21 (39%) procedures. Median follow-up was 18 months (range one to 117 months). Initial complete response (CR) was 29%, partial response 27%, stable disease 18% and progressive disease 27%. Predictors of better initial response were low disease burden and previous treatment. One or more treatments after ILI were common (65%). At 12 months, 19% of ILI patients had died from melanoma but 44% of surviving patients experienced limb CR. At 24 months, 57% of surviving patients experienced limb CR. The quality of life in the surviving, contactable patients according to the Toronto Extremity Salvage Score was 89%.Even if ILI does not result in CR for melanoma intransit metastases. it may slow disease progression as a single therapy, but more frequently in combination with other modalities.La perfusion d’un membre isolé (PMI) libère une chimiothérapie à faible dose par des sondes percutanées afin de traiter les métastases en transit des mélanomes.Décrire l’expérience de deux centres régionaux spécialisés à l’égard de la PMI.Les chercheurs ont réalisé une analyse rétrospective des patients qui ont subi une PMI entre 2002 et 2012. Ils ont mesuré les résultats à l’aide des critères de réponse de l’OMS, du score de toxicité de Wieberdink et de la fonction des membres à long terme selon le score de sauvetage des membres de Toronto (TESS).Les chercheurs ont analysé le cas de 52 patients (âge moyen de 66 ans [plage de 27 à 90 ans], 65 % de femmes et jambe [traitée] dans 86 % des cas) ayant eu 54 PMI. Dans 21 (39 %) des interventions, le score de toxicité de Wieberdink s’élevait à 3 ou plus. Le suivi médian était de 18 mois (plage de un à 117 mois). La réponse complète (RC) initiale était de 29 %, la réponse partielle de 27 %, la stabilisation de 18 % et l’évolution de 27 %. Un faible fardeau de la maladie et un traitement antérieur étaient les prédicteurs d’une meilleure réponse initiale. Il était courant d’administrer au moins un traitement après la PMI (65 %). Au bout de 12 mois, 19 % des patients étaient décédés à cause du mélanome, mais 44 % des survivants présentaient une RC du membre. Au bout de 24 mois, 57 % des survivants présentaient une RC du membre. La qualité de vie des survivants non perdus au suivi s’établissait à 89 % d’après le TESS.Même si la PMI ne suscite pas une RC des métastases en transit des mélanomes, elle peut ralentir l’évolution de la maladie seule, mais surtout en association avec d’autres modalités.

A Web-based synoptic operative reporting system (WebSMR) incorporates implicit guidelines and real-time feedback of a surgeon's practice compared with provincial data. This study compares rates of total mastectomy (TM) between the overall provincial and WebSMR patients and examines decision-making factors in WebSMR patients.Patients treated for invasive breast cancer (2007 to 2011) were identified from WebSMR and the Alberta Cancer Registry. Reports include surgery type and reasons for TM.Among 5,787 patients in WebSMR (2007 to 2011), TM rate decreased from 48% to 42% (P.001). In 2011, the provincial cancer registry recorded a 56% TM rate compared to 42% in WebSMR patients. Patient preference accounted for 36% in the latter group.In WebSMR patients, TM rates were lower than the overall provincial rate and decreased significantly during the study period. Reasons are unclear, but guidelines and real-time feedback likely plays a role.

There are few established indications for sentinel lymph node biopsy (SLNB) in breast ductal carcinoma in situ (DCIS). This study examines factors contributing to the high rate of SLNB in DCIS in Alberta, Canada.Patients who underwent definitive surgery from January 2009 to July 2011 for DCIS diagnosed on preoperative core-needle biopsy were identified using a provincial synoptic operative report database (WebSMR). The relationship between baseline patient and tumor characteristics and treatment with total mastectomy (TM), use of SLNB, and upstaging were examined.There were 394 patients identified in the study cohort. Mean age was 57 years, and average preoperative tumor size was 3 cm. Overall, 148 patients (37.6 %) underwent TM; predictors were preoperative tumor size [odds ratio (OR), 1.92 per 1-cm increase in size; 95 % CI 1.65-2.24] and surgeon. Upstaging to invasive cancer at surgery occurred in 23 %, predicted only by preoperative tumor size (OR 1.14 per 1 cm; 95 % CI 1.03-1.27). SLNB was performed in 306 patients overall (77 %) and 140 of those treated with BCS (61 %). Predictors of SLNB were larger preoperative tumor size (OR 1.55 per 1 cm; 95 % CI 1.18-2.04) and the surgeon. In patients treated with BCS, 3 patients who were upstaged had positive SLNs (0.2 mm), and no patients with DCIS had a positive SLN.SLNB use is high in patients undergoing BCS for DCIS. Tumor size and the operating surgeon predicted SLNB use. Despite a 23 % upstaging rate, the rate of clinically significant positive SLNs in patients treated with BCS is low, supporting omission of upfront SLNB.

Background and Objectives Evaluation of the management of DCIS poses challenges, as standard breast cancer outcome measures such as mortality do not apply. We have developed quality indicators (QIs) to measure the quality of DCIS treatment in Alberta, Canada. Methods A modified Delphi process was used to determine QIs in the treatment of DCIS after review of evidence-based clinical practice guidelines. Patients diagnosed with DCIS from 2000 to 2001 (cohort 1) and 2009–2010 (cohort 2) were identified from the Alberta Cancer Registry and QIs were retrospectively abstracted. Results The expert panel developed eight QIs to assess the overall quality of care for DCIS patients. Five hundred eighty eligible patients were identified in the two cohorts. There was significant improvement in radiation oncology referral, radiation post lumpectomy and complete pathology reporting. Axillary staging significantly increased from 20% (axillary dissection in cohort 1) to 60% (sentinel node biopsy in cohort 2). Other QIs did not differ significantly. Conclusions By developing QIs, performance measures for DCIS may assessed and compared over time. Although there have been significant improvements with pathology reporting and radiation oncology assessment and treatment, axillary staging rates are unexpectedly high, necessitating further investigation.

Aims To assess the eligibility, uptake and impediments to tamoxifen use in high-risk women attending a risk management clinic due to family history. Patients and methods All patients with a germline mutation in a cancer predisposing gene or at high genetic risk (based on family history) attending a Breast and Ovarian cancer risk management clinic from February 2014 to May 2015 received both verbal and written evidence-based information on preventive therapy and were recommended to consider endocrine prevention if not contraindicated. Endocrine therapy initiation, use and cessation were captured. Patient eligibility was analysed and reasons for declining, ceasing or contraindications for medication use were recorded. Results During the study period, 237 women were seen over 305 consultations for breast surveillance and preventative therapy discussion. They comprised 38 BRCA1 and 42 BRCA2 mutation carriers, 4 with Peutz-Jegher syndrome, 153 with a strong family history. Their median age was 39.4 years. Endocrine preventative was considered and discussed with all but 19 women. Of the remaining 218, 34 chose bilateral prophylactic mastectomy, while endocrine preventative was not recommended in 50 women due to contraindications and 25 women declined treatment due to their intention to fall pregnant. In 118 patients who remained eligible, 18.6% (22) tried prevention and 9.4% (14) remained on therapy. Conclusions Physician-reluctance is not a dominant reason for poor uptake of endocrine prevention even by high-risk premenopausal women in a specialised risk management clinic. Many women are not eligible, and most elect for alternative options.

Rapid identification of acute colonic pseudo-obstruction (ACPO), or Ogilvie's syndrome, is paramount in the management of this condition, which, if unresolved, can progress to bowel ischemia and perforation with significant morbidity and mortality. We present the first case report, to our knowledge, of ACPO following total laparoscopic hysterectomy. We describe the presentation and management of ACPO in a patient who underwent uncomplicated total laparoscopic hysterectomy to treat menorrhagia and dysmenorrhea after declining conservative treatment. Following initial conservative management, the patient rapidly deteriorated and required laparotomy for clinically suspected cecal ischemia. Cecal resection, colonic decompression, and end ileostomy formation were performed. A brief review of the current literature is presented with respect to the case report.

Mycobacterium ulcerans (MU) is the third common mycobacterial infection after tuberculosis and leprosy. In endemic areas, MU ulcers should be considered in the differential diagnosis of any unusual or nonhealing lesion or ulcer. Diagnosis and treatment should be instigated promptly. Delay may lead to disfiguring or disabling scars. Surgical management, therefore, should aim towards early excision, with clear margins of the ulcer. We present 4 consecutive patients treated by our department within a 6-month period for MU ulcers. The presentation, diagnosis and surgical management are described. Based on our experience and after reviewing the literature, we have developed a surgical algorithm for the management of MU ulcers.

Mohs micrographic surgery (MMS) is an accepted treatment for nonmelanoma skin cancer and has an evolving role in melanoma.To review oncologic outcomes of MMS and wide local excision (WLE) treatments for facial melanoma.A retrospective review of patients with invasive melanoma of the face between 1997 and 2007 identified from the Alberta Cancer Registry (Canada) was performed. Outcome measures were local recurrence (recurrence2 cm from excision scar), distant recurrence (regional or systemic), and disease-specific survival.One hundred fifty-one patients were available for analysis (60 MMS, 91 WLE). Median follow-up time was 48 months. The groups differed in tumor location and mitotic rate. Overall, there was no significant difference in 5-year local recurrence (7.9% WLE vs 6.2% MMS, p = .58), regional or systemic recurrence (18.8% vs 8.8%, p = 0.37) or disease-specific survival (82.8% vs 92.4%, p = .59). Breslow thickness was the only consistent predictor of local recurrence or other recurrence and disease-specific survival on multivariate analysis. Subset analysis of tumors with Breslow thickness less than 2 mm did not reveal any difference in outcomes.Mohs micrographic surgery has oncologic outcomes of local recurrence, distant recurrence and overall survival similar to those of WLE for invasive facial melanoma.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is an important procedure for the investigation and management of pancreaticobiliary disease. There is a recognized potential for significant morbidity, and a number of studies have identified patient and operator risk factors for the development of complications, including small case volume. We look at the outcomes of ERCP from a single operator at a rural centre and compare these with published figures. Method: Findings from 700 consecutive ERCP were collected prospectively between August 1997 and May 2006. Patients were included on an intention to treat basis, and all predetermined morbidity criteria were recorded. Results: Five hundred and forty-four therapeutic and 156 diagnostic ERCP were included in the study. There were a total of 40 complications (5.71%), with three cases of ERCP-specific mortality (0.4%). The success of therapeutic intervention was 94.3%. Conclusions: The importance of comparing personal audit to published prospective studies has been emphasized. This has provided quality assurance finding, confirming that comparable success rates, morbidity and mortality are possible in a low-volume rural centre with an operator who has been properly trained and has ongoing ties with a tertiary hepatobiliary unit, a dedicated and skilled local team and suitable patient selection.
