Free fibula mandible reconstruction for osteoradionecrosis is more challenging than for primary cancer.

INTRODUCTION: Osteoradionecrosis (ORN) of the mandible is an unfortunate potential sequela of radiotherapy for head and neck cancer. In advanced cases of ORN, mandibulectomy, and free fibula flap reconstruction are required. We hypothesized that patients undergoing fibula free flap reconstruction and mandibulectomy for ORN pose unique challenges and experience more complications than patients undergoing fibula free flaps after oncologic mandibulectomy. METHODS: After IRB approval, we created a database of all free fibula flaps for mandible reconstruction from April 2005 through February 2019. Medical records were retrospectively reviewed for patient and surgical characteristics and postoperative outcomes. RESULTS: Four-hundred seventy-nine patients met the inclusion criteria (168 ORN vs. 311 non-ORN patients). Propensity-matching was performed based on age, BMI, smoking status, preoperative chemotherapy, and virtual surgery planning use, which yielded 159 patients in each group. ORN patients received more double-skin-island fibula flaps than non-OR patients (20.8% vs. 5.7%, p < 0.001). Recipient artery other than the facial artery was utilized more commonly in ORN patients (42.1% vs. 17.0%, p < 0.001). In the unmatched cohort, ORN patients had higher rates of delayed wound healing (26.2% vs. 16.8%, p = 0.01) and surgical site infections (21.4% vs. 13.2%, p = 0.02). Rates of flap loss, return to the operating room, hematoma, operative time, and length of stay were similar between the groups. On logistic regression analysis, osteoradionecrosis was an independent risk factor for delayed wound healing. CONCLUSION: Based on these data, mandibular reconstruction with fibula flaps for osteoradionecrosis appears more complicated than mandible reconstruction following de novo cancer resection. Surgeons should anticipate employing two skin islands for intraoral and extraoral resurfacing, utilizing unconventional recipient vessels, and managing the delayed wound healing that ensues more commonly than non-ORN patients.

Component Separation Decreases Hernia Recurrence Rates in Abdominal Wall Reconstruction with Biologic Mesh.

BACKGROUND: It is not clear whether mesh-reinforced anterior component separation (CS) for abdominal wall reconstruction (AWR) results in better outcomes than mesh-reinforced primary fascial closure (PFC) without CS, particularly when acellular dermal matrix is used. The authors compared outcomes of CS versus PFC repair in AWR procedures aiming to determine whether CS results in better outcomes. METHODS: This retrospective study of prospectively collected data included 461 patients who underwent AWR with acellular dermal matrix during a 10-year period at an academic cancer center. The primary endpoint was hernia recurrence; the secondary outcome was surgical-site occurrence (SSO). RESULTS: A total of 322 patients (69.9%) who underwent mesh-reinforced AWR with CS (AWR-CS) and 139 (30.1%) who underwent AWR with PFC (AWR-PFC) without CS were compared. AWR-PFC repairs had a higher hernia recurrence rate than AWR-CS repairs (10.8% versus 5.3%; P = 0.002) but similar overall complication (28.8% versus 31.4%; P = 0.580) and SSO (18.7% versus 25.2%; P = 0.132) rates. CS repairs experienced significantly higher wound separation (17.7% versus 7.9%; P = 0.007), fat necrosis (8.7% versus 2.9%; P = 0.027), and seroma (5.6% versus 1.4%; P = 0.047) rates than PFC repairs. The best cutoff with respect to hernia recurrence was 7.1 cm of abdominal defect width. CONCLUSION: AWR-CS repair resulted in a lower hernia recurrence rate than AWR-PFC but, despite the additional surgery, had similar SSO rates on long-term follow-up. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Outcomes for 160 Consecutive Lateral Arm Free Flaps for Head and Neck Reconstruction.

OBJECTIVE: Examine outcomes for lateral arm autologous tissue transfer in head and neck reconstruction. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary cancer center. METHODS: All patients who underwent traditional lateral arm, extended lateral arm, and lateral forearm flaps for head and neck reconstruction from 2012 to 2022 were assessed. Disabilities of the arm, shoulder, and hand (DASH) was measured. Factors associated with complications and enteral or mixed diet were evaluated by multivariable regression. RESULTS: Among 160 patients followed for a median of 2.3 ± 2.1 years, defects were 54% oral tongue, 18% external, 9% maxilla, 8% buccal mucosa, 9% floor of mouth, and 3% pharynx. Flap types (and median pedicle lengths) were 41% traditional lateral arm (8 cm), 25% extended lateral arm (11.5 cm), and 34% lateral forearm (14 cm). All donor sites were closed primarily; 19.6% and 0% of patients had increased DASH scores 2 and 12 weeks after reconstruction. Major complications occurred in 18.1% of patients, including 6.3% reoperation, 6.9% readmission, 3.7% fistula, and 1.8% flap loss. Complications were independently associated with peripheral vascular disease (odds ratio [OR]: 5.71, 95% confidence interval [CI]: 1.5-21.6, P = .01), pharyngeal defects (OR: 11.3, 95% CI: 1.4-94.5, P = .025), and interposition vein grafts (OR: 3.78, 95% CI: 1.1-13.3, P = .037). CONCLUSION: The lateral arm free flap was safe, versatile, and reliable for head and neck reconstruction with low donor-site morbidity. Complications occurred in a fifth of patients and were associated with peripheral vascular disease, pharyngeal defects, and vein grafts.

The lateral forearm flap versus traditional upper extremity flaps: A comparison of donor site morbidity and flap thickness.

INTRODUCTION: The lateral forearm flap (LFF) is a thin fasciocutaneous flap with a donor site that can be closed primarily. METHODS: A retrospective analysis of donor site morbidity and hand function was performed in patients who underwent a radial forearm flap (RFF), ulnar artery perforator flap (UAPF), or LFF. Flap thickness was evaluated radiographically in 50 control patients. RESULTS: Of 134 patients (lateral forearm flap: n = 49, RFF: n = 47, UAPF: n = 38), the LFF demonstrated significantly faster return to baseline hand grip strength (3 months vs. 12 months in RFF and UAPF; p < 0.001), had significantly fewer donor site complications (6.1% compared to 6.4% in RFF and 28.9% in UAPF; p = 0.003) and fewer sensory deficits (2.0% compared to 6.4% in RFF and 15.8% in UAPF sites; p = 0.013). The radiographic study confirmed the LFF to be the thinnest of all upper extremity flap options. CONCLUSIONS: The LFF is an excellent forearm-based flap option with thin, pliable tissue and low donor site morbidity.

Long-term Surgical and Patient-Reported Outcomes Comparing Skin-Preserving, Staged Versus Delayed Microvascular Breast Reconstruction.

BACKGROUND: Skin-preserving, staged, microvascular, breast reconstruction often is preferred in patients requiring postmastectomy radiotherapy (PMRT) but may lead to complications. We compared the long-term surgical and patient-reported outcomes between skin-preserving and delayed microvascular breast reconstruction with and without PMRT. METHODS: We conducted a retrospective, cohort study of consecutive patients who underwent mastectomy and microvascular breast reconstruction between January 2016 and April 2022. The primary outcome was any flap-related complication. The secondary outcomes were patient-reported outcomes and tissue-expander complications. RESULTS: We identified 1002 reconstructions (672 delayed; 330 skin-preserving) in 812 patients. Mean follow-up was 24.2 ± 19.3 months. PMRT was required in 564 reconstructions (56.3%). In the non-PMRT group, skin-preserving reconstruction was independently associated with shorter hospital stay (ß - 0.32, p = 0.045) and lower odds of 30-days readmission (odds ratio [OR] 0.44, p = 0.042), seroma (OR 0.42, p = 0.036), and hematoma (OR 0.24, p = 0.011) compared with delayed reconstruction. In the PMRT group, skin-preserving reconstruction was independently associated with shorter hospital stay (ß - 1.15, p < 0.001) and operative time (ß - 97.0, p < 0.001) and lower odds of 30-days readmission (OR 0.29, p = 0.005) and infection (OR 0.33, p = 0.023) compared with delayed reconstruction. Skin-preserving reconstruction had a 10.6% tissue expander loss rate and did not differ from delayed reconstruction in terms of patient-reported satisfaction with breast, psychosocial well-being, or sexual well-being. CONCLUSIONS: Skin-preserving, staged, microvascular, breast reconstruction is safe regardless of the need for PMRT, with an acceptable tissue expander loss rate, and is associated with improved flap outcomes and similar patient-reported quality of life to that of delayed reconstruction.

Profunda Artery Perforator Flap Tongue Reconstruction: An Effective and Safe Alternative to the Anterolateral Thigh Flap.

BACKGROUND: The anterolateral thigh (ALT) perforator flap is a workhorse flap for tongue reconstruction. The authors present an alternative option using the profunda artery perforator (PAP) flap for glossectomy reconstruction compared to the ALT flap. METHODS: A retrospective review was conducted of 65 patients who underwent subtotal or total glossectomy reconstruction between 2016 and 2020 (46 ALT vs. 19 PAP flaps). Flap volume was assessed using CT scans at two different time points. Quality of life and functional outcomes were measured using the MD Anderson Symptom Inventory for head and neck cancer (MDASI-HN). RESULTS: Patients undergoing a PAP flap had significantly lower BMI compared to ALT flaps (22.7±5.0 vs. 25.8±5.1; p=0.014). Donor site and recipient site complications were similar as was the mean flap volume seven months after surgery (30.9% for ALT vs. 28.1% for PAP; p=0.93). Radiation and chemotherapy did not appear to have a significant effect on flap volume change over time. The most frequently reported high-severity items in MDASI-HN were swallowing/chewing and voice/speech for both cohorts. Patients who had reconstruction with a PAP flap had significantly better swallowing function (p=0.034). CONCLUSION: Both the PAP and ALT flaps appear to be safe and effective choices for subtotal and total tongue reconstruction. The PAP flap can serve as an alternative donor site, especially in the setting of malnourished patients with thin lateral thigh thickness undergoing reconstruction of extensive glossectomy defects.

Ensuring Safety While Achieving Beauty: An Evidence-Based Approach to Optimizing Mastectomy and Autologous Breast Reconstruction Outcomes in Patients with Obesity.

BACKGROUND: Although obesity has previously been associated with poor outcomes after mastectomy and breast reconstruction, its impact across the WHO obesity classification spectrum and the differential effects of various optimization strategies on patient outcomes have yet to be delineated. We sought to examine the impact of WHO obesity classification on intraoperative surgical and medical complications, postoperative surgical and patient-reported outcomes of mastectomy and autologous breast reconstruction, and delineate outcomes optimization strategies for obese patients. STUDY DESIGN: This is a review of consecutive patients who underwent mastectomy and autologous breast reconstruction from 2016 to 2022. Primary outcomes were complication rates. Secondary outcomes were patient-reported outcomes and optimal management strategies. RESULTS: We identified 1,640 mastectomies and reconstructions in 1,240 patients with mean follow-up of 24.2 ± 19.2 months. Patients with class II/III obesity had higher adjusted risk of wound dehiscence (odds ratio [OR] 3.20; p < 0.001), skin flap necrosis (OR 2.60; p < 0.001), deep venous thrombosis (OR 3.90; p < 0.033), and pulmonary embolism (OR 15.3; p = 0.001) than nonobese patients. Obese patients demonstrated significantly lower satisfaction with breasts (67.3 ± 27.7 vs 73.7 ± 24.0; p = 0.043) and psychological well-being (72.4 ± 27.0 vs 82.0 ± 20.8; p = 0.001) than nonobese patients. Unilateral delayed reconstructions were associated with independently shorter hospital stay (ß -0.65; p = 0.002) and lower adjusted risk of 30-day readmission (OR 0.45; p = 0.031), skin flap necrosis (OR 0.14; p = 0.031), and pulmonary embolism (OR 0.07; p = 0.021). CONCLUSIONS: Obese women should be closely monitored for adverse events and lower quality of life, offered measures to optimize thromboembolic prophylaxis, and advised on the risks and benefits of unilateral delayed reconstruction.

Sensory Outcomes for Inferior Alveolar Nerve Reconstruction with Allograft following Free Fibula Mandible Reconstruction.

BACKGROUND: As patient survival with head and neck cancer has improved, treatment goals have had to evolve to focus on improving quality of life. Traditionally, patients who have undergone mandibulectomy are left with an insensate chin and lower lip secondary to resection of the inferior alveolar nerve (IAN). The purpose of this study was to critically evaluate the authors' initial experience using processed nerve allografts (PNA) for IAN reconstruction following oncologic mandibulectomy and reconstruction with free fibula osteocutaneous flaps and to assess their patients' sensory outcomes. METHODS: The authors performed a retrospective review of the first 32 patients who underwent immediate IAN reconstruction with PNA at the time of oncologic mandibulectomy and mandible reconstruction with free fibula osteocutaneous flaps at The University of Texas M. D. Anderson Cancer Center over a 1-year period. Semmes-Weinstein filament sensory testing was conducted at multiple surgical follow-up appointments to evaluate the quality of sensory recovery. RESULTS: Thirteen of the 32 patients underwent postoperative Semmes-Weinstein filament testing. All 13 patients demonstrated partial return of sensation. At a mean follow-up of 8.33 months, the average level of sensation was 60.93% that of the unaffected side of the lower lip. CONCLUSIONS: Patients were consistently afforded improvement in lower lip sensation using PNA-based IAN grafting as an adjunct to free fibula-based mandible reconstruction. The procedure adds no additional surgical morbidity and has shown consistent positive results.

Vascularized Condyle Reconstruction with Free Medial Femoral Trochlea and Fibular Flow-through Flaps.

The free fibula flap is the gold standard in reconstruction of oncologic mandibular defects. When the mandibular condyle is resected, reconstruction of the temporomandibular joint (TMJ) continues to pose a unique challenge to the reconstructive surgeon. Several conventional methods have been described, including costochondral grafts, bone grafts, and alloplastic prostheses. These nonvascularized options are rarely employed in the oncologic patient receiving postoperative radiation therapy due to high rates of resorption, nonunion, and failure. The authors describe a novel technique for mandibular and TMJ reconstruction utilizing the fibula free flap as a flow through for a medial femoral trochlea flap for vascularized mandible and condylar reconstruction. This technique provides a vascularized cartilaginous surface to articulate with the glenoid fossa, making it an attractive option for the oncologic patient undergoing postoperative radiation therapy.

The Cost Utility of Virtual Surgical Planning and Computer-Assisted Design/Computer-Assisted Manufacturing in Mandible Reconstruction Using the Free Fibula Osteocutaneous Flap.

BACKGROUND: The use of virtual surgical planning and computer-assisted design and computer-assisted manufacturing (CAD/CAM) has become widespread for mandible reconstruction with the free fibula flap. However, the cost utility of this technology remains unknown. METHODS: The authors used a decision tree model to evaluate the cost utility, from the perspective of a hospital or insurer, of mandible reconstruction using CAD/CAM relative to the conventional (non-CAD/CAM) technique for the free fibula flap. Health state probabilities were obtained from a published meta-analysis. Costs were estimated using 2018 Centers for Medicare and Medicaid Services data. Overall expected cost and quality-adjusted life-years (QALYs) were assessed using a Monte Carlo simulation and sensitivity analyses. Cost effectiveness was defined as an incremental cost utility ratio (ICUR) less than the empirically accepted willingness-to-pay value of $50,000 per QALY. RESULTS: Although CAD/CAM reconstruction had a higher expected cost compared with the conventional technique ($36,487 vs. $26,086), the expected QALYs were higher (17.25 vs. 16.93), resulting in an ICUR = $32,503/QALY; therefore, the use of CAD/CAM in free fibula flap mandible reconstruction was cost-effective relative to conventional technique. Monte Carlo sensitivity analysis confirmed CAD/CAM's superior cost utility, demonstrating that it was the preferred and more cost-effective option in the majority of simulations. Sensitivity analyses also illustrated that CAD/CAM remains cost effective at an amount less than $42,903 or flap loss rate less than 4.5%. CONCLUSION: This cost utility analysis suggests that mandible reconstruction with the free fibula osteocutaneous flap using CAD/CAM is more cost effective than the conventional technique.

Outcomes for recurrent oral cavity squamous cell carcinoma.

OBJECTIVES: We sought to determine overall survival (OS), prognostic factors, cost, and functional outcomes after surgery for locally recurrent oral cavity squamous cell carcinoma (OCSCC). MATERIALS AND METHODS: We retrospectively reviewed 399 cases of locally recurrent OCSCC from 1997 to 2011, of which 259 patients were treated with salvage surgery. Survival and prognostic factors were evaluated using univariable and multivariable Cox regression, the Kaplan-Meier method, and the log-rank test. RESULTS: The 5-year OS for patients undergoing surgical salvage, nonsurgical therapy, or supportive care was 44.2%, 1.5%, and 0%, respectively. For patients who underwent surgical salvage, 133 (51%) patients experienced a second recurrence at a median of 17 months. Factors associated with OS included disease-free interval ≤ 6 months (P =.0001), recurrent stage III-IV disease (P <.0001), and prior radiation (P =.0001). Patients with both advanced stage and prior radiation had a 23% 5-year OS, compared with 70% for those with neither risk (P <.001). Functionally, 85% of patients had > 80% speech intelligibility and 81% were able to eat by mouth following salvage surgery. Of the patients who required tracheostomy, 78% were decannulated. The adjusted median hospital and professional charges for patients were $129,696 (range $9,238-$956,818). CONCLUSIONS: Patients with recurrent OCSCC who underwent salvage surgery have favorable functional outcomes with half of alive at 5 years but poorer OS for advanced disease, disease-free interval ≤ 6 months, and prior radiation. Additionally, treatment is associated with high cost, and about half of patients ultimately develop another recurrence.

A Prospective, Randomized Comparison of Clinical Outcomes with Different Processing Techniques in Autologous Fat Grafting.

BACKGROUND: Autologous fat grafting is a useful tool in breast reconstruction. The authors have previously demonstrated a difference in the rate of processing adipose grafts in a randomized time and motion clinical trial. The purpose of this study was to compare clinical outcomes in commonly used grafting systems. METHODS: Three methods to prepare adipose grafts were compared: a passive washing filtration system (Puregraft system), an active washing filtration system (Revolve system), and centrifugation (Coleman technique). Postoperative complications, rates of fat necrosis, revision procedures, and additional imaging were recorded. RESULTS: Forty-six patients were included in the prospective, randomized study (15 active filtration, 15 passive filtration, and 16 centrifugation). Their mean age was 54 years and mean body mass index was 28.6 kg/m 2 . The mean length of follow-up was 16.9 ± 4 months. The overall complication rate was 12.1 percent. The probability of fat necrosis was no different between the groups (active filtration, 15 percent versus passive filtration, 14.3 percent] versus centrifugation, 8 percent; p = 0.72). Fat necrosis was highest in patients with breast conservation before grafting (60 percent; p = 0.011). There was no significant difference in contour irregularity (active filtration, 40 percent versus passive filtration, 38 percent versus centrifugation, 36 percent; p = 0.96) or additional grafting (active filtration, 40 percent versus passive filtration, 24 percent versus centrifugation, 32 percent; p = 0.34). CONCLUSIONS: This is the first prospective, randomized study to compare clinical outcomes of adipose graft preparation. There was no significant difference in early complications, fat necrosis, or rates of additional grafting among the study groups. There was significantly higher risk of fat necrosis in patients with previous breast conservation treatment regardless of processing technique. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

Microvascular Breast Reconstruction in the Era of Value-Based Care: Use of a Cosurgeon Is Associated with Reduced Costs, Improved Outcomes, and Added Value.

BACKGROUND: Reducing complications while controlling costs is a central tenet of value-based health care. Bilateral microvascular breast reconstruction is a long operation with a relatively high complication rate. Using a two-surgeon team has been shown to improve safety in bilateral microvascular breast reconstruction; however, its impact on cost and efficiency has not been robustly studied. The authors hypothesized that a cosurgeon for bilateral microvascular breast reconstruction is safe, effective, and associated with reduced costs. METHODS: The authors retrospectively reviewed all patients who underwent bilateral microvascular breast reconstruction with either a single surgeon or surgeon/cosurgeon team over an 18-month period. Charges were converted to costs using the authors' institutional cost-to-charge ratio. Surgeon opportunity costs were estimated using time-driven activity-based costing. Propensity scoring controlled for baseline characteristics between the two groups. A locally weighted logistic regression model analyzed the cosurgeon's impact on outcomes and costs. RESULTS: The authors included 150 bilateral microvascular breast reconstructions (60 single-surgeon and 90 surgeon/cosurgeon reconstructions) with a median follow-up of 15 months. After matching, the presence of a cosurgeon was associated with a significantly reduced mean operative duration (change in operative duration, -107 minutes; p < 0.001) and cost (change in total cost, -$1101.50; p < 0.001), which was even more pronounced when surgeon/cosurgeon teams worked together frequently (change in operative duration, -132 minutes; change in total cost, -$1389; p = 0.007). The weighted logistic regression models identified that a cosurgeon was protective against breast-site complications and trended toward reduced overall and major complication rates. CONCLUSION: The practice of using a of cosurgeon appears to be associated with reduced costs and improved outcomes, thereby potentially adding value to bilateral microvascular breast reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Computer-Aided Design and Manufacturing versus Conventional Surgical Planning for Head and Neck Reconstruction: A Systematic Review and Meta-Analysis.

BACKGROUND: Virtual surgical planning and computer-aided design/computer-aided manufacturing (CAD/CAM) for complex head and neck reconstruction has a number of cited advantages over conventional surgical planning, such as increased operative efficiency, fewer complications, improved osseous flap union, immediate osseointegrated dental implant placement, and superior functional and aesthetic outcomes. The authors performed a systematic review and meta-analysis of the available evidence on CAD/CAM maxillofacial reconstruction with the primary purpose of determining which approach is more efficacious. METHODS: In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a PubMed and Embase database search was performed to identify English-language, human-subject studies of CAD/CAM-assisted head and neck reconstruction. All comparative studies were included in a meta-analysis to identify differences in operative time, ischemia time, surgical-site occurrence, microvascular complication, and partial or total flap loss between the two groups. All included studies (comparative and noncomparative) were used in the systematic review, summarizing the various flap characteristics, technical nuances, and functional and aesthetic outcomes. RESULTS: Twelve articles were included in the meta-analysis, representing 277 patients in the CAD/CAM group and 419 patients in the conventional group. CAD/CAM was associated with 65.3 fewer minutes of operating room time (95 percent CI, -72.7 to -57.9 minutes; p < 0.0001) and 34.8 fewer minutes of ischemia time (95 percent CI, -38 to -31.5 minutes; p < 0.0001). There were no significant differences in surgical-site occurrence, nonunion, flap loss, microvascular complications, or hardware-related complications. CONCLUSIONS: CAD/CAM is associated with shorter operating room and ischemia times. There are no significant differences in flap or hardware-related complications between CAD/CAM and conventional surgical planning.

The Effect of Lipoaspirate Processing Technique on Complications in Autologous Fat Grafting for Breast Reconstruction: A Propensity Score Analysis Study.

BACKGROUND: The use of autologous fat grafting (AFG) is becoming increasingly common as an adjunct to breast reconstruction. However, there is a paucity of data comparing the varying processing devices. OBJECTIVES: The goal of this study was to compare the outcomes of 2 commercially available AFG processing devices. METHODS: A retrospective review was conducted of patients who underwent AFG with dual-filter (Puregraft) or single-filter (Revolve) processing systems between 2016 and 2019. Propensity score matching was utilized to adjust for confounding. A total of 38 breasts from the Puregraft group were matched with 38 breasts from the Revolve group. RESULTS: Matching was successful in achieving a similar distribution of baseline characteristics between the 2 groups. The mean number of AFG sessions was comparable between the 2 groups (P = 0.37) with a similar median total volume (Puregraft, 159 mL vs Revolve, 130 mL; P = 0.23). Complication rates were similar between the 2 devices (Puregraft, 26%; Revolve, 18%; P = 0.47). Patients with at least 1 complication had higher overall AFG volume (median, 200 mL vs 130 mL; P = 0.03) and number of sessions (mean, 2.4 vs 1.8, P = 0.009) compared with those without any postoperative complication. CONCLUSIONS: Overall complication rates were comparable between 2 commonly used, commercially available AFG processing systems, and therefore the choice of which to use should be based on surgeon preference. Future studies are underway to decipher whether either system offers superior graft retention, cosmetic, or patient-reported outcomes.

Relationship Between Financial Toxicity and Surgical Treatment for Early-Stage Breast Cancer: A Propensity Score-Matched Comparison of Breast-Conserving Therapy and Mastectomy.

BACKGROUND: Financial toxicity (FT) can lead to decreased quality of life and poor treatment outcomes. However, there is limited published data on the extent to which the various surgical treatment approaches for early-stage breast cancer are determinants for FT. STUDY DESIGN: We performed a single-institution cross-sectional survey of adult female patients with stage 0 to II breast cancer undergoing unilateral breast-conserving therapy or unilateral mastectomy. FT was measured using the Comprehensive Score for Financial Toxicity (COST) survey. Propensity matching was performed to optimize comparability of study groups. A multivariate regression model was used to identify factors associated with worsening FT as a robustness check. Our secondary end point was prevalence of coping strategies associated with cost of cancer care. RESULTS: Among 294 patients who met inclusion criteria, 203 underwent breast-conserving therapy and 91 received mastectomy. We generated 72 total matched pairs and noted no differences in demographic and socioeconomic characteristics. Of these, 55 pairs had complete COST information, which was comparable on adjusted analysis (26.6 vs 24.7; p = 0.481). High annual income (ß = 4.83; p < 0.001) and supplemental insurance (ß = 5.37; p < 0.001) were significantly associated with higher COST scores, while change in employment status (ß = -4.81; p < 0.001) correlated significantly with lower COST scores. No significant differences were observed in coping strategies. CONCLUSIONS: Choice of BCT or mastectomy was not associated with a differential risk for FT in early-stage cancer. Decisions on ablative approach should be made based on patient preferences and disease-specific criteria. Transparent counseling on FT for high-risk populations promotes patient-centricity.

The Profunda Artery Perforator Flap: A Versatile Option for Head and Neck Reconstruction.

BACKGROUND: Although the profunda artery perforator flap has gained popularity in breast reconstruction, it has not been well described for reconstruction of head and neck defects. The authors report their experience with free profunda artery perforator flaps in postoncologic head and neck reconstruction. METHODS: A retrospective review of all free profunda artery perforator flaps used for head and neck reconstruction from 2016 to 2019 was performed. RESULTS: Overall, 61 profunda artery perforator flap reconstructions were performed: 45 single independent flaps, 12 in conjunction with a second free flap, and four in combination with two other free flaps. The profunda artery perforator flaps were most commonly used for reconstruction of the tongue (n = 19), cheek (n = 11), parotid (n = 10), and maxilla (n = 6). The profunda artery perforator flaps averaged 7.1 × 12.1 × 1.9 cm, with a mean pedicle length of 11.5 cm. The A, B, and C perforators were located at mean distances of 7.4 cm (range, 4 to 11.5 cm), 11.7 cm (range, 8 to 18 cm), and 16.1 cm (range, 14 to 20.5 cm) from the pubic tubercle along the axis of the adductor longus muscle and 7.9 cm (range, 7 to 11cm), 7.6 cm (range, 7 to 15.5 cm), and 7.2 cm (range, 6 to 16 cm) posterior and perpendicular to the axis. There were three partial flap losses. Eight patients (13 percent) had recipient-site complications necessitating operative intervention: four for vascular compromise of the profunda artery perforator flap, two for hematoma evacuation, and two for infection. Donor-site complications were noted in seven patients (11 percent), two of whom required operative intervention. CONCLUSIONS: The profunda artery perforator flap is a versatile and reliable flap with consistent anatomy and a low complication rate. The profunda artery perforator flap seems to be a reasonable alternative for reconstruction of head and neck defects. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

A Randomized Prospective Time and Motion Comparison of Techniques to Process Autologous Fat Grafts.

BACKGROUND: Time and motion studies provide a reliable methodology to quantify efficiency and establish recommendations for best practices in autologous fat grafting. The purpose of this study was to compare the rate of graft processing of three frequently used systems for graft preparation. METHODS: The authors conducted a prospective randomized comparison of three methods to prepare adipose tissue for autologous fat grafting: an active filtration system (Revolve; LifeCell Corporation, Branchburg, N.J.), a passive filtration system (PureGraft 250; Cytori Therapeutics, San Diego, Calif.), and centrifugation. An independent observer collected data according to the study's behavioral checklist. The primary outcome measure was rate of adipose tissue processed. RESULTS: Forty-six patients (mean age, 54 years; mean body mass index, 28.6 kg/m2) were included in the study (15 per arm; one patient was included with intention to treat after a failed screening). The rate of adipose tissue preparation was greater for the active filtration system compared with the others (active filtration: 9.98 ml/min versus passive filtration: 5.66 ml/min versus centrifugation: 2.47 ml/min). Similarly, there was a significant difference in total grafting time (active: 82.7 ± 8.51 minutes versus passive: 152 ± 13.1 minutes, p = 0.0005; versus centrifugation: 209.9 ± 28.5 minutes, p = 0.0005); however, there was no difference in total operative time (p = 0.82, 0.60). CONCLUSIONS: As the number of fat grafting procedures increases, there is interest in developing techniques to harvest, process, and inject fat to improve clinical outcomes and operative efficiency. The results of this study indicate that an active fat processing system is more time efficient at graft preparation than a passive system or centrifugation.
