The Multi Centre Canadian Acellular Dermal Matrix Trial (MCCAT): study protocol for a randomized controlled trial in implant-based breast reconstruction

BACKGROUND: The two-stage tissue expander/implant (TE/I) reconstruction is currently the gold standard method of implant-based immediate breast reconstruction in North America. Recently, however, there have been numerous case series describing the use of one-stage direct to implant reconstruction with the aid of acellular dermal matrix (ADM). In order to rigorously investigate the novel application of ADM in one-stage implant reconstruction, we are currently conducting a multicentre randomized controlled trial (RCT) designed to evaluate the impact on patient satisfaction and quality of life (QOL) compared to the two-stage TE/I technique. METHODS/DESIGNS: The MCCAT study is a multicenter Canadian ADM trial designed as a two-arm parallel superiority trial that will compare ADM-facilitated one-stage implant reconstruction compared to two-stage TE/I reconstruction following skin-sparing mastectomy (SSM) or nipple-sparing mastectomy (NSM) at 2 weeks, 6 months, and 12 months. The source population will be members of the mastectomy cohort with stage T0 to TII disease, proficient in English, over the age of 18 years, and planning to undergo SSM or NSM with immediate implant breast reconstruction. Stratified randomization will maintain a balanced distribution of important prognostic factors (study site and unilateral versus bilateral procedures). The primary outcome is patient satisfaction and QOL as measured by the validated and procedure-specific BREAST-Q. Secondary outcomes include short- and long-term complications, long-term aesthetic outcomes using five standardized photographs graded by three independent blinded observers, and a cost effectiveness analysis. DISCUSSION: There is tremendous interest in using ADM in implant breast reconstruction, particularly in the setting of one-stage direct to implant reconstruction where it was previously not possible without the intermediary use of a temporary tissue expander (TE). This unique advantage has led many patients and surgeons alike to believe that one-stage ADM-assisted implant reconstruction should be the procedure of choice and should be offered to patients as the first-line treatment. We argue that it is crucial that this technique be scientifically evaluated in terms of patient selection, surgical technique, complications, aesthetic outcomes, cost-effectiveness, and most importantly patient-reported outcomes before it is promoted as the new gold standard in implant-based breast reconstruction.

Locoregional Management of in-Transit Metastasis in Melanoma: An Ontario Health (Cancer Care Ontario) Clinical Practice Guideline

Objective: The purpose of this guideline is to provide guidance on appropriate management of satellite and in-transit metastasis (itm) from melanoma. Methods: The guideline was developed by the Program in Evidence-Based Care (pebc) of Ontario Health (Cancer Care Ontario) and the Melanoma Disease Site Group. Recommendations were drafted by a Working Group based on a systematic review of publications in the medline and embase databases. The document underwent patient- and caregiver-specific consultation and was circulated to the Melanoma Disease Site Group and the pebc Report Approval Panel for internal review; the revised document underwent external review. Recommendations: “Minimal itm” is defined as lesions in a location with limited spread (generally 1–4 lesions); the lesions are generally superficial, often clustered together, and surgically resectable. “Moderate itm” is defined as more than 5 lesions covering a wider area, or the rapid development (within weeks) of new in-transit lesions. “Maximal itm” is defined as large-volume disease with multiple (>15–20) 2–3 cm nodules or subcutaneous or deeper lesions over a wide area. (1) In patients presenting with minimal itm, complete surgical excision with negative pathologic margins is recommended. In addition to complete surgical resection, adjuvant treatment may be considered. (2) In patients presenting with moderate unresectable itm, consider using this approach for localized treatment: intralesional interleukin 2 or talimogene laherparepvec as 1st choice, topical diphenylcyclopropenone as 2nd choice, or radiation therapy as 3rd choice. Evidence is insufficient to recommend intralesional bacille Calmette– Guérin or CO2 laser ablation outside of a research setting. (3) In patients presenting with maximal itm confined to an extremity, isolated limb perfusion, isolated limb infusion, or systemic therapy may be considered. In extremely select cases, amputation could be considered as a final option in patients without systemic disease after discussion at a multidisciplinary case conference. (4) In cases in which local, regional, or surgical treatments for itm might be ineffective or unable to be performed, or if a patient has systemic metastases at the same time, systemic therapy may be considered

An Enhanced Recovery after Surgery Pathway for Microvascular Breast Reconstruction Is Safe and Effective

Background:. The aim of this study was to develop, implement, and evaluate a standardized perioperative enhanced recovery after surgery (ERAS) clinical care pathway in microsurgical abdominal-based breast reconstruction. Methods:. Development of a clinical care pathway was informed by the latest ERAS guideline for breast reconstruction. Key features included shortened preoperative fasting, judicious fluids, multimodal analgesics, early oral nutrition, early Foley catheter removal, and early ambulation. There were 3 groups of women in this cohort study: (1) traditional historical control; (2) transition group with partial implementation; and (3) ERAS. Narcotic use, patient-reported pain scores, antiemetic use, time to regular diet, time to first walk, hospital length of stay, and 30-day postoperative complications were compared between the groups. Results:. After implementation of the pathway, the use of parenteral narcotics was reduced by 88% (traditional, 112 mg; transition, 58 mg; ERAS, 13 mg; P < 0.0001), with no consequent increase in patient-reported pain. Patients in the ERAS cohort used less antiemetics (7.0, 5.3, 2.2 doses, P < 0.0001), returned to normal diet 19 hours earlier (46, 39, 27 hours, P < 0.0001), and walked 25 hours sooner (75, 70, 50 hours, P < 0.0001). Overall, hospital length of stay was reduced by 2 days in the ERAS cohort (6.6, 5.6, 4.8 days, P < 0.0001), without an increase in rates of major complications (9.5%, 10.1%, 8.3%, P = 0.9). Conclusions:. A clinical care pathway in microsurgical breast reconstruction using the ERAS Society guideline promotes successful early recovery

Oncology education for family medicine residents: a national needs assessment survey

Background: This study aimed to determine the current state of oncology education in Canadian family medicine postgraduate medical education programs (FM PGME) and examine opinions regarding optimal oncology education in these programs. Methods: A survey was designed to evaluate ideal and current oncology teaching, educational topics, objectives, and competencies in FM PGMEs. The survey was sent to Canadian family medicine (FM) residents and program directors (PDs). Results: In total, 150 residents and 17 PDs affiliated with 16 of 17 Canadian medical schools completed the survey. The majority indicated their programs do not have a mandatory clinical rotation in oncology (79% residents, 88% PDs). Low rates of residents (7%) and PDs (13%) reported FM residents being adequately prepared for their role in caring for cancer patients (p = 0.03). Residents and PDs believed the most optimal method of teaching oncology is through clinical exposure (65% residents, 80% PDs). Residents and PDs agreed the most important topics to learn (rated ≥4.7 on 5-point Likert scale) were: performing pap smears, cancer screening/prevention, breaking bad news, and approach to patient with increased cancer risk. According to residents, other important topics such as appropriate cancer patient referrals, managing cancer complications and post-treatment surveillance were only taught at frequencies of 52, 40 and 36%, respectively. Conclusions: Current FM PGME oncology education is suboptimal, although the degree differs in the opinion of residents and PDs. This study identified topics and methods of education which could be focussed upon to improve FM oncology education.Other UBCNon UBCReviewedFacult
