Acellular Dermal Matrix Provides Durable Long-Term Outcomes in Abdominal Wall Reconstruction: A Study of Patients with Over 60 Months of Follow-up.

BACKGROUND: Ventral hernia repair (VHR) is one of the most commonly performed procedures in the United States, but studies assessing the long-term outcomes of VHR using biologic mesh are scarce. OBJECTIVE: We sought to determine the rates of hernia recurrence (HR) and surgical site occurrences (SSOs) in a large cohort of patients who underwent AWR with biologic mesh. METHODS: We conducted a retrospective cohort study of patients who underwent AWR using either porcine ADM (PADM) or bovine ADM (BADM) from 2005 to 2019. We analyzed the full cohort and a subset of our population with minimum long-term follow-up (LTF) of 5 years. The primary outcome measure was HR. Secondary outcomes were SSOs. RESULTS: We identified a total of 725 AWRs (49.5% PADM, 50.5% BADM). Mean age was 69 ± 11.5 years and mean body mass index was 31 ± 7 kg/m 2 . Forty-two percent of the defects were clean at the time of AWR, 44% were clean-contaminated, and 14% were contaminated/infected. Mean defect size was 180 ± 174 cm 2 , mean mesh size was 414 ± 203 cm 2 . Hernia recurred in 93 patients (13%), with cumulative HR rates of 4.9%, 13.5%, 17.3%, and 18.8% at 1, 3, 5, and 7 years, respectively. There were no differences in HR ( P = 0.83) and SSO ( P = 0.87) between the 2 mesh types. SSOs were identified in 27% of patients. In our LTF group (n = 162), the HR rate was 16%. Obesity, bridged repair, and concurrent stoma presence/creation were independent predictors of HR; component separation was protective against HR. CONCLUSIONS: Despite its use in complex AWR, ADM provides durable long-term outcomes with relatively low recurrence rates.

Allograft vs Xenograft Bioprosthetic Mesh in Tissue Expander Breast Reconstruction: A Blinded Prospective Randomized Controlled Trial.

BACKGROUND: With the increased use of acellular dermal matrix (ADM) in breast reconstruction, the number of available materials has increased. There is a relative paucity of high-quality outcomes data for use of different ADMs. OBJECTIVES: The goal of this study was to compare the outcomes between a human (HADM) and a bovine ADM (BADM) in implant-based breast reconstruction. METHODS: A prospective, single-blinded, randomized controlled trial was conducted to evaluate differences in outcomes between HADM and BADM for patients undergoing immediate tissue expander breast reconstruction. Patients with prior radiation to the index breast were excluded. Patient and surgical characteristics were collected and analyzed. RESULTS: From April 2011 to June 2016, a total of 90 patients were randomized to a mesh group, with 68 patients (HADM, 36 patients/55 breasts; BADM, 32 patients/48 breasts) included in the final analysis. Baseline characteristics were similar between the 2 groups. No significant differences in overall complication rates were identified between HADM (n = 14, 25%) and BADM (n = 13, 27%) (P = 0.85). Similar trends were identified for major complications and complications requiring reoperation. Tissue expander loss was identified in 7% of HADM patients (n = 4) and 17% of BADM patients (n = 8) (P = 0.14). CONCLUSIONS: Similar complication and implant loss rates were found among patients undergoing immediate tissue expander breast reconstruction with HADM or BADM. Regardless of what material is used, careful patient selection and counseling, and cost consideration, help to improve outcomes and sustainability in immediate breast reconstruction.

Synthetic Mesh Versus Acellular Dermal Matrix for Oncologic Chest Wall Reconstruction: A Comparative Analysis.

BACKGROUND: Management of chest wall defects after oncologic resection is challenging due to multifactorial etiologies. Traditionally, skeletal stabilization in chest wall reconstruction (CWR) was performed with synthetic prosthetic mesh. The authors hypothesized that CWR for oncologic resection defects with acellular dermal matrix (ADM) is associated with a lower incidence of complications than synthetic mesh. METHODS: Consecutive patients who underwent CWR using synthetic mesh (SM) or ADM at a single center were reviewed. Only oncologic defects involving resection of at least one rib and reconstruction with both mesh and overlying soft tissue flaps were included in this study. Patients' demographics, treatment factors, and outcomes were prospectively documented. The primary outcome measure was surgical-site complications (SSCs). The secondary outcomes were specific wound-healing events, cardiopulmonary complications, reoperation, and mortality. RESULTS: This study investigated 146 patients [95 (65.1%) with SM; 51 (34.9%) with ADM] who underwent resection and CWR of oncologic defects. The mean follow-up period was 29.3 months (range 6-109 months). The mean age was 51.5 years, and the mean size of the defect area was 173.8 cm2. The SM-CWR patients had a greater number of ribs resected (2.7 vs. 2.0 ribs; p = 0.006) but a similar incidence of sternal resections (29.5% vs. 23.5%; p = 0.591) compared with the ADM-CWR patients. The SM-CWR patients experienced significantly more SSCs (32.6% vs. 15.7%; p = 0.027) than the ADM-CWR patients. The two groups had similar rates of specific wound-healing complications. No differences in mortality or reoperations were observed. CONCLUSIONS: The ADM-CWR patients experienced fewer SSCs than the SM-CWR patients. Surgeons should consider selectively using ADM for CWR, particularly in patients at higher risk for SSCs.

The effect of sarcopenia on perioperative complications in abdominally based free-flap breast reconstruction.

PURPOSE: The identification of patient-specific risk factors, which predict morbidity following abdominally based microvascular breast reconstruction is difficult. Sarcopenia is a proxy for patient frailty and is an independent predictor of complications in a myriad of surgical disciplines. We predict that sarcopenic patients will be at higher risk for surgical complications following abdominally based microvascular breast reconstruction. METHODS: A retrospective study of all patients who underwent delayed abdominally based autologous breast reconstruction following postmastectomy radiation therapy from 2007 to 2013 at a single institution was conducted. Univariate and multiple logistic regression models were used to assess the effect of sarcopenia on postoperative outcomes. RESULTS: Two hundred and eight patients met the inclusion criteria, of which 30 met criteria for sarcopenia (14.1%). There were no significant differences in demographics between groups. There were no significant differences in minor (36.7% vs 44.4%; P = .43) or major (16.7% vs 25.3%; P = .36) complications between groups as well as hospital length of stay. Multivariable logistic regression demonstrated that a staged reconstruction with the use of a tissue expander was the only consistent variable, which predicted major complications (OR, 2.24; 95% CI, 1.18-4.64; P = .015). CONCLUSIONS: Sarcopenia does not predispose to minor or major surgical complications in patients who undergo abdominally based microsurgical breast reconstruction.

Complications of Wise-Pattern Compared With Vertical Scar Mastopexy/Breast Reduction in Oncoplastic Breast-Conserving Surgery.

BACKGROUND: Oncoplastic breast-conserving surgery (OBCS) is most commonly performed using established or modified mastopexy/breast reduction techniques. Although the comparative complication profiles of Wise-pattern mastopexy/breast reduction techniques compared with vertical scar techniques are well understood, outcomes in the setting of OBCS are unknown. METHODS: A retrospective study was conducted of all patients that underwent OBCS using mastopexy/breast reduction techniques at a single center over a 6-year period. Patients who underwent Wise-pattern techniques were compared with those who underwent vertical scar techniques. Demographic, treatment, and outcomes data were collected. Descriptive statistics were used, and multivariate analysis was performed to evaluate the relationship between these multiple variables and complications. RESULTS: Of 413 eligible patients, 278 patients (67.3%) received a Wise-pattern technique and 135 (32.7%) underwent a vertical scar technique. The overall complication rate was significantly higher in the Wise-pattern than in the vertical scar group (30.6% vs 18.5%, respectively; P = 0.012), as was the major complication rate (11.9% vs 4.4%; P = 0.011) including need for additional surgery for complications (6.8% vs 1.5%; P = 0.029). Complications resulted in a delay to any adjuvant therapy in 20 patients (4.8%); however, the difference between the groups was not significant (6.1% for Wise pattern vs 2.2% for vertical scar; P = 0.098). In a multivariable logistic model, use of a Wise-pattern technique (odds ratio, 0.37 [95% confidence interval, 0.14-0.99]; P = 0.049) was a significant predictor of major complications. CONCLUSIONS: The Wise-pattern mastopexy/breast reduction OBCS technique was associated with a significantly higher complication and major complication rate than vertical scar techniques. The findings should be considered during choice of surgical technique in oncoplastic breast conservation.

Prior Radiotherapy Does Not Affect Abdominal Wall Reconstruction Outcomes: Evidence from Propensity Score Analysis.

BACKGROUND: Prior abdominal wall radiotherapy (XRT) adversely affects wound healing, but data are limited on how prior XRT may affect abdominal wall reconstruction (AWR) outcomes. The purpose of this study was to determine whether prior abdominal wall radiotherapy is associated with a higher incidence of complications following AWR for a hernia or oncologic resection defect. METHODS: We performed a retrospective study of consecutive patients who underwent complex AWR using acellular dermal matrix (ADM) at a single center. We compared outcomes between patients who underwent prior XRT that directly involved the abdominal wall and those who did not receive XRT. Propensity score match-paired and multivariate analyses were performed. RESULTS: A total of 511 patients (130 [25.4 %] with prior XRT; 381 [74.6 %] without prior XRT) underwent AWR with ADM for repair of a complex hernia or oncologic resection defect. Mean follow-up was 31.4 months, mean XRT dose was 48.9 Gy, and mean time between XRT and reconstruction was 19.2 months. XRT AWR patients underwent more flap reconstructions (14.6 vs. 5.0 %, P < 0.001) but fewer component separations (61.5 vs. 71.4 %; P = 0.036) than non-XRT AWR patients. The two groups had similar rates of hernia recurrence (8.5 vs. 9.4 %; P = 0.737) and surgical site occurrence (25.4 vs. 23.4 %; P = 0.640). In the propensity score-matched subgroups, there were no differences in hernia recurrence, surgical site occurrence, and wound healing complication rates. CONCLUSIONS: Prior XRT does not adversely affect outcomes in AWR. However, surgeons should be aware of the higher likelihood of needing a soft tissue flap reconstruction for soft tissue replacement when performing AWR after XRT.

Operative and Oncologic Outcomes in 9861 Patients with Operable Breast Cancer: Single-Institution Analysis of Breast Conservation with Oncoplastic Reconstruction.

BACKGROUND: Oncoplastic reconstruction is an approach that enables patients with locally advanced or adversely located tumors to undergo breast conserving surgery (BCS). The objectives were to identify the use of BCS with oncoplastic reconstruction (BCS + R) and determine the operative and oncologic outcomes compared with other breast surgical procedures for breast cancer. METHODS: This retrospective cohort study interrogated a single institution's prospectively maintained databases to identify patients who underwent surgery for breast cancer between 2007 and 2014. Surgeries were categorized as BCS, BCS + R, total mastectomy (TM), or TM with immediate reconstruction (TM + R). Demographic and clinicopathologic characteristics and postoperative complications were analyzed. RESULTS: There were 10,607 operations performed for 9861 patients. Median follow-up was 3.4 years (range, 0-9.1 years). The use of BCS + R had a nearly fourfold increase in the percentage of all breast cancer surgeries during the study period; 75 % of patients who underwent BCS + R had a T1 or T2 tumor. There was no difference in the use of BCS + R compared with BCS for any quadrant of the breast except the lower outer quadrant (11.1 vs. 6.8 %; p < .0001). BCS + R had a lower rate of seroma formation (13.4 vs. 18 %; p = .002) and positive or close margins compared with BCS (5.8 vs. 8.3 %; p = .04). There was no difference in overall survival or recurrence-free survival when comparing BCS and BCS + R. CONCLUSIONS: Patients undergoing BCS + R are not disadvantaged in terms of complications and short-term (3-year) outcomes compared with BCS patients or patients who underwent TM.

Reconstructive breast implant-related infections: Prevention, diagnosis, treatment, and pearls of wisdom.

Implant-based reconstructions are increasingly utilized following mastectomy in the prevention and treatment of breast cancer. However, these implants are associated with a high rate of infection, which is a major complication that can lead to implant removal, delay in adjuvant radiation and chemotherapy, and increase in health care costs. Early clinical signs and symptoms of infection, such as erythema, warmth, and tenderness, are challenging to discern from expected postsurgical responses. Furthermore, when atypical features are present or the patient's condition does not improve on adequate antimicrobials, the clinician should be prompted to consider an alternative noninfectious etiology. Herein we highlight the key elements of the preventive, diagnostic, and multidisciplinary therapeutic approach to salvaging the infected breast implant; review several infectious disease mimickers; and provide many pearls of wisdom that the practicing clinician must be familiar with and be able to manage in an effective and successful manner.

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.

Locoregional interaction of ixabepilone (ixempra) after breast cancer radiation.

BACKGROUND: Radiation recall is an acute inflammatory reaction within a previously irradiated field triggered by chemotherapy administration. We observed a series of patients with unexpectedly severe reactions that included radiation recall and delayed healing when patients received the microtubule stabilizer ixabepilone (Ixempra; Bristol-Myers Squibb, Princeton, NJ) after radiation. We therefore decided to evaluate our experience in patients receiving ixabepilone following radiotherapy. METHODS: We performed a retrospective chart review of all patients treated with curative intent in the Department of Radiation Oncology at the MD Anderson Cancer Center from 2008-2011 who received any ixabepilone after completion of external-beam radiation therapy. These patients received adjuvant ixabepilone on one of two protocols, either for locally advanced breast cancer or for metastatic breast cancer. In total, 19 patients were identified and their charts were subsequently reviewed for evidence of ixabepilone-related toxicity. RESULTS: Of the 19 patients identified who received ixabepilone following radiation therapy, three (15.8%) had unexpectedly serious reactions in the months following radiation therapy. Complications included delayed wound closure and drain placement into the seroma, intense erythema, and delayed wound closure and grade 4 chest wall necrosis requiring latissimus flap and skin grafting. The average number of days between the end of radiation therapy and documentation of reaction was 99. CONCLUSIONS: Ixabepilone chemotherapy may induce radiation recall and delayed wound healing when used shortly after the completion of external-beam radiotherapy. Significant clinical interactions have not been previously reported and merit further evaluation.

Incidence of and Risk Factors for Incisional Hernia After Hepatectomy for Colorectal Liver Metastases.

BACKGROUND: Incisional hernia (IH) is common after major abdominal surgery; however, the incidence after hepatectomy for cancer has not been described. We analyzed incidence of and risk factors for IH after hepatectomy for colorectal liver metastases (CLM). METHODS: Patients who underwent open hepatectomy with midline or reverse-L incision for CLM at a single institution between 2010 and 2018 were retrospectively analyzed. Postoperative CT scans were reviewed to identify IH and the time from hepatectomy to hernia. Cumulative IH incidence was calculated using competing risk analysis. Risk factors were assessed using Cox proportional hazards model analysis. The relationship between IH incidence and preoperative body mass index (BMI) was estimated using a generalized additive model. RESULTS: Among 470 patients (median follow-up: 16.9 months), IH rates at 12, 24, and 60 months were 41.5%, 51.0%, and 59.2%, respectively. Factors independently associated with IH were surgical site infection (HR: 1.54, 95% CI 1.16-2.06, P = 0.003) and BMI > 25 kg/m2 (HR: 1.94, 95% CI 1.45-2.61, P < 0.001). IH incidence was similar in patients undergoing midline and reverse-L incisions and patients who received and did not receive a bevacizumab-containing regimen. The 1-year IH rate increased with increasing number of risk factors (zero: 22.2%; one: 46.8%; two: 60.3%; P < 0.001). Estimated IH incidence was 10% for BMI of 15 kg/m2 and 80% for BMI of 40 kg/m2. CONCLUSION: IH is common after open hepatectomy for CLM, particularly in obese patients and patients with surgical site infection. Surgeons should consider risk-mitigation strategies, including alternative fascial closure techniques.

Prospective evaluation of the nipple-areola complex sparing mastectomy for risk reduction and for early-stage breast cancer.

BACKGROUND: Psychological effects of mastectomy for women with breast cancer have driven treatments that optimize cosmesis while strictly adhering to oncologic principles. Although skin-sparing mastectomy is oncologically safe, questions remain regarding the use of nipple-areola complex (NAC)-sparing mastectomy (NSM). We prospectively evaluated NSM for patients undergoing mastectomy for early-stage breast cancer or risk reduction. METHODS: We enrolled 33 early-stage breast cancer and high-risk patient; 54 NSMs were performed. NAC viability and surgical complications were evaluated. Intraoperative and postoperative pathologic assessments of the NAC base tissue were performed. NAC sensory, cosmetic and quality of life (QOL) outcomes were also assessed. RESULTS: Twenty-one bilateral and 12 unilateral NSMs were performed in 33 patients, 37 (68.5%) for prophylaxis and 17 (31.5%) for malignancy. Mean age was 45.4 years. Complications occurred in 16 NACs (29.6%) and 6 skin flaps (11.1%). Operative intervention for necrosis resulted in 4 NAC removals (7.4%). Two (11.8%) of the 17 breasts with cancer had ductal carcinoma-in-situ at the NAC margin, necessitating removal at mastectomy. All evaluable patients had nipple erection at 6 and 12 months postoperatively. Cosmetic outcome, evaluated by two plastic surgeons, was acceptable in 73.0% of breasts and 55.8% of NACs, but lateral displacement occurred in most cases. QOL assessment indicated patient satisfaction. CONCLUSIONS: NSM is technically feasible in select patients, with a low risk for NAC removal resulting from necrosis or intraoperative detection of cancer, and preserves sensation and QOL. Thorough pathologic assessment of the NAC base is critical to ensure disease eradication.

Robotic harvest of the latissimus dorsi muscle: laboratory and clinical experience.

Minimally invasive harvest of the latissimus dorsi (LD) muscle is a desirable goal because of both the wide utility of this muscle and the length of incision required to harvest it. In this study, robotic harvest of the LD muscle was evaluated in a cadaver model and clinical series. Ten LD flaps were robotically harvested in eight cadavers. Positioning, port placement, procedural steps, instrumentation, and technical obstacles were all critically analyzed and reported. After modifying the technique based on experience gained in the cadaver study, eight LD muscles were robotically harvested and transferred in eight patients. Access included a short axillary incision and two additional port sites along the anterior border of the muscle. Insufflation was used to maintain the optical cavity. Indications included pedicled flaps for implant-based breast reconstruction and free flaps for scalp reconstruction. All flaps were successfully transferred without converting to open technique. In the clinical series, average time for setup and port placement was 23 minutes, and average robotic time was 1 hour and 51 minutes. There were no major complications. Robotic harvest of the LD is feasible and effective and permits full muscle harvest without a visible incision.

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.

Desmoid tumor: current multidisciplinary approaches.

Desmoid tumor, also known as aggressive or deep fibromatosis or musculoaponeurotic fibromatosis, is a rare tumor. Desmoids are characterized by their ability to locally infiltrate; while frequently locally recurrent, they lack metastatic potential. Desmoids typically arise within the abdomen or abdominal wall, but can be extra-abdominal, most commonly in the proximal extremities. The infiltrative and recurrent nature of desmoid tumors can render surgical resection challenging if acceptable function and cosmesis is to be maintained. Consequently, desmoid management frequently involves a multidisciplinary approach that combines the expertise of several surgical specialists, for example, surgical oncologists and plastic surgeons, and also medical and radiation oncologists. As will be reviewed in this article, working together before undertaking any definitive therapies, such expert teams may be optimally positioned to offer patients superior functional and aesthetic outcomes based on maximizing therapeutic efficacy while minimizing treatment-related morbidities.

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.

Correlation Between Financial Toxicity, Quality of Life, and Patient Satisfaction in an Insured Population of Breast Cancer Surgical Patients: A Single-Institution Retrospective Study.

BACKGROUND: The relationship between treatment-related, cost-associated distress "financial toxicity" (FT) and quality-of life (QOL) in breast cancer patients remains poorly characterized. This study leverages validated patient-reported outcomes measures (PROMs) to analyze the association between FT and QOL and satisfaction among women undergoing ablative breast cancer surgery. STUDY DESIGN: This is a single-institution cross-sectional survey of all female breast cancer patients (>18 years old) who underwent lumpectomy or mastectomy between January 2018 and June 2019. FT was measured via the 11-item COmprehensive Score for financial Toxicity (COST) instrument. The BREAST-Q and SF-12 were used to asses condition-specific and global QOL, respectively. Responses were linked with demographic and clinical data. Pearson correlation coefficient and multivariable regression were used to examine associations. RESULTS: Our analytical sample consisted of 532 patients; mean age 58, mostly white (76.7%), employed (63.7%), married/committed (73.7%), with 64.3% undergoing reconstruction. Median household income was $80,000 to $120,000/year, and mean COST score was 28.0. After multivariable adjustment, a positive relationship for all outcomes was noted; lower COST (greater cost-associated distress) was associated with lower BREAST-Q and SF-12 scores. This relationship was strongest for BREAST-Q psychosocial well-being, for which we observed a 0.89 (95% CI 0.76-1.03) change per unit change in COST score. CONCLUSIONS: Financial toxicity captured in this study correlates with statistically significant and clinically important differences in BREAST-Q psychosocial well-being, patient satisfaction with reconstructed breasts, and SF-12 global mental and physical quality of life. Treatment costs should be included in the shared decision-making for breast cancer surgery. Future prospective outcomes research should integrate COST.

Differences in Time Burden across Local Therapy Strategies for Early-stage Breast Cancer.

"Time burden" (time required during treatment) is relevant when choosing a local therapy option for early-stage breast cancer but has not been rigorously studied. We compared the time burden for three common local therapies for breast cancer: (1) lumpectomy plus whole-breast irradiation (Lump+WBI), (2) mastectomy without radiation or reconstruction (Mast alone), and (3) mastectomy without radiation but with reconstruction (Mast+Recon). METHODS: Using the MarketScan database, we identified 35,406 breast cancer patients treated from 2000 to 2011 with these local therapies. We quantified the total time burden as the sum of inpatient days (inpatient-days), outpatient days excluding radiation fractions (outpatient-days), and radiation fractions (radiation-days) in the first two years postdiagnosis. Multivariable regression evaluated the effect of local therapy on inpatient-days and outpatient-days adjusted for patient and treatment covariates. RESULTS: Adjusted mean number of inpatient-days was 1.0 for Lump+WBI, 2.0 for Mast alone, and 3.1 for Mast+Recon (P < 0.001). Adjusted mean number of outpatient-days was 42.9 for Lump+WBI, 42.2 for Mast alone, and 45.8 for Mast+Recon (P < 0.001). The mean number of radiation-days for Lump+WBI was 32.4. Compared with Mast+Recon (48.9 days), total adjusted time burden was 4.7 days shorter for Mast alone (44.2 days) and 27.4 days longer for Lump+WBI (76.3 days). However, use of a 15 fraction WBI regimen would reduce the time burden differential between Lump+WBI and Mast+Recon to just 10.0 days. CONCLUSIONS: Although Mast+Recon confers the highest inpatient and outpatient time burden, Lump+WBI carries the highest total time burden. Increased use of hypofractionation will reduce the total time burden for Lump+WBI.

Soft-Tissue Reconstruction after Composite Vertebrectomy and Chest Wall Resection for Spinal Tumors.

BACKGROUND: Oncologic resections involving both the spine and chest wall commonly require immediate soft-tissue reconstruction. The authors hypothesized that reconstructions of composite resections involving both the thoracic spine and chest wall would have a higher complication rate than reconstructions for resections limited to the thoracic spine alone. METHODS: The authors performed a retrospective analysis of all consecutive patients who underwent a thoracic vertebrectomy and soft-tissue reconstruction from 2002 to 2017. Patients were divided into two groups: those whose defect was limited to the thoracic spine and those who required a composite resection involving the chest wall. RESULTS: One hundred patients were included. Composite resection patients had larger defects, as indicated by a greater incidence of multilevel vertebrectomies (70.2 percent versus 17 percent; p = 0.001). Thoracic spine patients were older (58.2 ± 10.4 years versus 48.6 ± 13.9 years; p < 0.001) and had a greater incidence of metastatic disease (88.7 percent versus 38.3 percent; p = 0.001). Univariate and multivariate logistic regression analyses demonstrated that composite resections were not significantly associated with a higher rate of surgical, medical, or overall complications. Multivariate logistic regression analysis of composite resection subgroup demonstrated that flap separation of the spinal cord from the intrapleural space was protective against complications (OR, 0.22; 95 percent CI, 0.05 to 0.81; p = 0.03). CONCLUSIONS: Despite the large defect size in composite resection patients, there was no increase in complications compared to thoracic spine patients. In composite resection patients, separating the exposed spinal cord from the intrapleural space with well-vascularized soft tissue was protective against complications. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Reconstruction of massive chest wall defects: A 20-year experience.

BACKGROUND: Large chest wall resections can result in paradoxical chest wall movement leading to prolonged ventilator dependence and major respiratory impairment. The purpose of this study was to determine as to which factors are predictive or protective of complications in massive oncologic chest wall defect reconstructions. METHODS: A retrospective review of a prospectively maintained database of consecutive patients who underwent immediate reconstruction of massive thoracic oncologic defects (≥5 ribs) was performed. Univariate and multivariate logistic regression analyses identified risk factors. RESULTS: We identified 59 patients (median age, 53 years) with a mean follow-up of 36 months. Rib resections ranged from 5 to 10 ribs (defect area, 80-690 cm2). Sixty-two percent of the patients developed at least one postoperative complication. Superior/middle resections were associated with increased risk of general and pulmonary complications (71.4% vs. 35.3%; OR 4.54; p = 0.013). The 90-day mortality rate following massive chest wall resection and reconstruction was 8.5%. Two factors that were significantly associated with shorter overall survival time were preoperative XRT and preoperative chemotherapy (p = 0.021 and p < 0.001, respectively). CONCLUSIONS: Patients with massive oncological thoracic defects have a high rate of reconstructive complications, particularly pulmonary, leading to prolonged ventilator dependence. Superior resections were more likely to be associated with increased pulmonary and overall complications. The length of postoperative recovery was significantly associated with the size of the defect, and larger defects had prolonged hospital stays. Because of the large dimensions of chest wall defects, almost half of the cases required flap coverage to allow for appropriate defect closure. Understanding the unique demands of these rare but challenging cases is critically important in predicting patient outcomes.
