RESUMO

BACKGROUND: Excision is routinely recommended for atypical ductal hyperplasia (ADH) found on core biopsy given cancer upstage rates of near 20%. Identifying a cohort at low-risk for upstage may avoid low-value surgery. Objectives were to elucidate factors predictive of upstage in ADH, specifically near-complete core sampling, to potentially define a group at low upstage risk. PATIENTS AND METHODS: This retrospective, cross-sectional, multi-institutional study from 2015 to 2019 of 221 ADH lesions in 216 patients who underwent excision or active observation (≥ 12 months imaging surveillance, mean follow-up 32.6 months) evaluated clinical, radiologic, pathologic, and procedural factors for association with upstage. Radiologists prospectively examined imaging for lesional size and sampling proportion. RESULTS: Upstage occurred in 37 (16.7%) lesions, 25 (67.6%) to ductal carcinoma in situ (DCIS) and 12 (32.4%) to invasive cancer. Factors independently predictive of upstage were lesion size ≥ 10 mm (OR 5.47, 95% CI 2.03-14.77, p < 0.001), pathologic suspicion for DCIS (OR 12.29, 95% CI 3.24-46.56, p < 0.001), and calcification distribution pattern (OR 8.08, 95% CI 2.04-32.00, p = 0.003, "regional"; OR 19.28, 95% CI 3.47-106.97, p < 0.001, "linear"). Near-complete sampling was not correlated with upstage (p = 0.64). All three significant predictors were absent in 65 (29.4%) cases, with a 1.5% upstage rate. CONCLUSIONS: The upstage rate among 221 ADH lesions was 16.7%, highest in lesions ≥ 10 mm, with pathologic suspicion of DCIS, and linear/regional calcifications on mammography. Conversely, 30% of the cohort exhibited all low-risk factors, with an upstage rate < 2%, suggesting that active surveillance may be permissible in lieu of surgery.

RESUMO

BACKGROUND: Robotic surgery (RS) has been increasingly incorporated into colorectal surgery (CRS) training. The degree to which RS has been integrated into CRS residency training is not well described. METHODS: A web-based survey was sent to all 2019 accredited CRS residency programs within the United States and Canada. Program directors (PDs) were queried on how robotic surgery had been integrated into their program, specifics on RS curriculum and opinions on RS training during general surgery residency. We compared survey responses by program type (university-based, university-affiliated programs, or independent programs) and by geographic region. In addition, a chi-square test was used to evaluate differences in survey responses with respect to robotic curriculum components. RESULTS: Of 66 programs, 42 (64%) responded to the survey. Of the responding programs, 35 (83%) were university-based or university-affiliated, while 7 (17%) were independent. Most programs were in the Midwest (33%). Forty-one (98%) reported having a surgical robot in use at their institution, with 95% reporting active participation of CRS residents in RS. While 74% of programs have a formal RS training curriculum for CRS residents, there was considerable variability in the curriculum elements employed by each institution, and the differences in proportions of these elements were significant (χ2 99.8, p < 0.001). The median operative approach to abdominopelvic cases was estimated to be 33% robotic, 40% laparoscopic and 20% open. There were no significant differences in the survey responses between university/university-affiliated and independent programs (p > 0.05) or among the different regions (p > 0.05). CONCLUSIONS: This study demonstrated that almost all CRS residencies have integrated RS and have trainees operating at the robotic console. Most programs have a robotics curriculum and there are expanding indications for RS within CRS. This expansion calls for discussion on implementation of training standards such as curricular requisites, baseline competency assessments, and definitions of minimum case requirements to ensure adequate training.

RESUMO

Axillary lymph node dissection (ALND) specimens should have at least ten-lymph nodes for examination according to established guidelines. Nonetheless, recent evidence suggests that neoadjuvant chemotherapy (NAC) results in fewer nodes in the specimen. We sought to examine if NAC patients have lower lymph node yield from ALND specimens and whether the number of lymph nodes in the specimen is correlated with pathologic complete response (pCR). Using the National Cancer Database (NCDB), a study cohort of female patients with node-positive, non-metastatic invasive breast cancer diagnosed from 2012 to 2015 was identified. The axillary lymph node retrieval count was compared in NAC and non-NAC patients and then correlated with pCR. A multivariable analysis was performed to identify factors that were associated with less than ten-lymph nodes in the ALND pathologic specimen. Of 56,976 patients identified, 27,197 (48%) received neoadjuvant chemotherapy; 29,779 (52%) did not. NAC patients failed to meet the ten-lymph node minimum in the ALND specimen more often than non-NAC patients (35% vs. 27%, p < 0.001). NAC patients with fewer than ten-lymph nodes were more likely to have a pCR than those with ten or more (22% vs. 16%, p < 0.001). On multivariable analysis, pCR of the primary tumor and receptor status were found to be independent predictors of having fewer than ten-lymph nodes in the ALND specimen. Node-positive breast cancer patients that underwent NAC were more likely to not meet the ten-lymph node standard. However, NAC patients who did not meet the minimum were also more likely to have a pCR compared to NAC patients who did. This suggests lower lymph node yield may not truly be a marker of lower quality surgery but rather a potential marker of NAC treatment effect.

RESUMO

Diagnostic mammography is routinely ordered, along with targeted breast ultrasound, to evaluate breast symptoms in women 30-39 years of age. However, in this age group, mammography is often limited by breast density and the probability of detecting an occult malignancy is low. We sought to evaluate whether diagnostic mammography detected any new incidental malignancies in women aged 30-39 years presenting with focal breast symptoms. This retrospective study included women 30-39 years of age who had a diagnostic mammogram performed for focal breast symptoms at a single institution from 2002 to 2017. Descriptive analyses were performed to determine the rate of incidental mammographic findings outside of the region of the presenting symptom that 1) led to additional imaging and/or biopsies and 2) were found to be malignant. During the 16-year study period, 1770 evaluations were performed, of which 249 (14.1%) were found to have an additional incidental mammographic abnormality. Further diagnostic imaging was required in 211 (11.3%), core biopsy in 67 (3.8%), and excisional biopsy in 8 (0.5%). None of the mammographically detected incidental findings resulted in a new diagnosis of breast cancer. In the evaluation of focal benign breast symptoms in women 30-39 years of age, diagnostic mammography did not detect any new incidental malignancies outside of the area of interest, but instead led to additional unavailing imaging and biopsy procedures. The mammography component of the diagnostic evaluation of younger average-risk women may potentially be omitted if the presenting symptom is determined to be benign with ultrasound alone.

RESUMO

ABSTRACT: Breast augmentation and reconstruction utilizing implants are among the most common plastic surgery procedures performed in the United States. A small proportion of these implants are removed each year. We report 2 cases where routine pathologic evaluation of capsulectomy specimens revealed squamous cell carcinoma associated with the breast implant capsule and discuss the possible pathogenesis of this unusual entity. Both patients had long-standing implants (>10 years) and presented with acute unilateral breast erythema and swelling. Intraoperatively, the capsules for both cases appeared thickened and calcified, containing extensive granulomatosis and keratinaceous debris invading into the chest wall. Extensive workup failed to find an occult primary. One patient died from a malignant pleural effusion secondary to tumor invasion during chemotherapy, and the second patient obtained stabilization of the mass after 5 weeks of chemotherapy but subsequently declined further surgical intervention. A thorough literature review was performed, and 5 similar reports were identified, involving 6 patients. All patients presented with similar clinical presentations as ours and had poor outcomes. The mean reporting age at diagnosis was 60 years, and the average time from initial implant to diagnosis was 25 years. Due to the small numbers of squamous cell carcinomas associated with breast implant capsules, the true association between the 2 is unknown. It is postulated that chronic inflammation/irritation from the breast implant and epithelialization of the capsule play a significant role in the disease process. This may represent a new entity of "chronic inflammatory capsular malignancies." Increased awareness of this entity may allow for earlier suspicion, diagnosis, and management.

RESUMO

BACKGROUND: Estrogen receptor (ER) and progesterone receptor (PR) status is pivotal to determining the prognosis and treatment of human epidermal growth factor 2 (HER2) receptor-negative invasive breast cancer. Frequently ER-positive (ER+) and/or PR-positive (PR+) cancers are labeled nonspecifically as "hormone receptor-positive" although only one is positive. This study aimed to evaluate and characterize the ER+PR- and ER-PR+ breast cancer phenotypes in reference to ER+PR+ cancers. METHODS: A retrospective cohort study of female patients with HER2-negative (HER2-) invasive breast cancer diagnosed in 2010-2015 was performed using the National Cancer Database. Cases were grouped into ER+PR+, ER-PR+, ER+PR-, and ER-PR- phenotypes to determine differences in patient demographics, tumor characteristics, and overall survival. RESULTS: Of 823,969 cases, 619,050 (75.1%) were ER+PR+, 79,777 (9.7%) were ER+PR-, 7006 (0.9%) were ER-PR+, and 118,136 (14.3%) were ER-PR-. Compared with the ER+PR+ group, the ER+PR- and ER-PR+ groups were more likely to be high-grade cancer (16.0% vs. 34.2% and 80.0%, respectively; p < 0.001), to have lymphovascular invasion (17.9% vs. 19.6% and 23.0%; p < 0.001), to be node-positive (13.5% vs. 19.7% and 26.3%; p < 0.001), to be stage 4 cancer (3.6% vs. 5.9% and 6.7%; p < 0.001), to have a higher multigene assay score (mean, 16.0 vs. 27.8 and 38.1; p < 0.001), and to have a worse survival (90.6% vs. 83.8% and 78.1%; p < 0.001). CONCLUSION: Single hormone receptor-positive breast cancer subtypes (ER+PR- and ER-PR+) are more likely to have unfavorable characteristics and worse survival than the ER+PR+ subtype, with the ER-PR+ subtype having outcomes similar to those for ER-PR- cancers. The single hormone receptor-positive subtypes, representing 10% of HER2- cancers, should be considered clinically distinct from ER+PR+ disease.

RESUMO

BACKGROUND: Lipomatous masses are the most common soft tissue tumors. While the majority are benign lipomas, it is important to identify those masses that are malignant prior to excision. Current guidelines recommend core needle biopsy (CNB) for all lipomatous masses larger than 3-5 cm. The objective of this study was to determine if routine preoperative CNB based on mass size is necessary, or if radiographic features can guide the need for CNB. MATERIALS AND METHODS: Patients who underwent excision of extremity or truncal lipomatous masses at a single institution from October 2014 to July 2017 were retrospectively reviewed. By protocol, preoperative imaging was routinely obtained for all masses larger than 5 cm. High-risk radiographic features (intramuscular location, septations, nonfat nodules, heterogeneity, and ill-defined margins) and surgical pathology were evaluated to determine patients most likely to benefit from preoperative CNB. RESULTS: Of 178 patients, 2 (1.1%) had malignant tumors on surgical pathology. All masses smaller than 5 cm were benign and, if imaging was obtained, had two or fewer high-risk radiographic features. Both of the patients with malignant tumors had masses larger than 5 cm, preoperative imaging that showed at least four high-risk radiographic features, and underwent CNB prior to excision. CONCLUSIONS: The overall rate of malignancy is very low. The results of this study suggest that lipomatous masses smaller than 5 cm without concerning clinical characteristics do not require preoperative imaging or CNB. Conversely, lipomatous masses larger than 5 cm should undergo routine MRI with subsequent CNB if multiple high-risk radiographic features are present.

RESUMO

OBJECTIVE: To determine if clinicopathologic (CP) factors could identify patients at "very low" and/or "very high" pretest probability of a high Oncotype DX (ODX) score. METHODS: A retrospective analysis of all patients that had ODX testing 2008-2018 at a single institution. RESULTS: Of 215 patients, all 16 (7.4%) with "all high" risk CP factors had high ODX scores, and all 45 (20.9%) over age 50 with "all low" risk CP factors had ODX recommendations for no chemotherapy. CONCLUSIONS: Oncotype DX results did not change chemotherapy recommendations in those with "very low" or "very high" pretest probability of high ODX scores.

RESUMO

BACKGROUND: Sentinel lymph node biopsy (SLNB) historically involves a separate appointment in the Radiology Department to undergo injection of the radiocolloid tracer (RT) the day of, or prior to, surgery, which can lead to disruptions in scheduling. Furthermore, the patient must endure an additional procedure. In a pilot study, intraoperative injection of the RT was previously shown to be equally as effective as preoperative injection. This study evaluates the efficacy of this method in a large cohort and examines factors associated with failure of the RT to reach the axilla. METHODS: A retrospective review of patients who underwent SLNB between June 2010 and June 2017 was performed. All patients were injected immediately following intubation with sulfur colloid and blue dye, unless contraindicated. Operative records were reviewed to determine whether sentinel nodes were identified and if gamma counts were detected. Patient and tumor characteristics were examined to identify factors related to failed RT uptake in the axilla. RESULTS: In 7 years, 453 SLNBs were performed, with sentinel nodes being detected in 447 (98.7%) of these SLNBs. In the six cases where no nodes were detected, all had a prior ipsilateral axillary procedure. Sentinel nodes were undetectable with the gamma probe in 16 (3.5%) cases; a prior axillary procedure was the only statistically significant independent variable associated with this failure. CONCLUSION: Intraoperative injection of the RT is highly effective in the detection of sentinel nodes in clinically node-negative breast cancer patients. Eliminating the need for a preoperative injection of RT can avoid scheduling conflicts and decrease patient morbidity.

RESUMO

BACKGROUND: It has become increasingly important to expose surgical residents to robotic surgery as its applications continue to expand. Single-site robotic cholecystectomy (SSRC) is an excellent introductory case to robotics. Resident involvement in SSRC is known to be feasible. Here, we sought to determine whether it is safe to introduce SSRC to junior residents. MATERIALS AND METHODS: A total of 98 SSRC cases were performed by general surgery residents between August 2015 and August 2016. Cases were divided into groups based on resident level: second- and third-years (juniors) versus fourth- and fifth-years (seniors). Patient age, gender, race, body mass index, and comorbidities were recorded. The number of prior laparoscopic cholecystectomies completed by participating residents was noted. Outcomes including operative time, console time, rate of conversion to open cholecystectomy, and complication rate were compared between groups. RESULTS: Juniors performed 54 SSRC cases, whereas seniors performed 44. There were no significant differences in patient age, gender, race, body mass index, or comorbidities between the two groups. Juniors had less experience with laparoscopic cholecystectomy. There was no significant difference in mean operative time (92.7 min versus 98.0 min, P = 0.254), console time (48.7 min versus 50.8 min, P = 0.639), or complication rate (3.7% versus 2.3%, P = 0.68) between juniors and seniors. CONCLUSIONS: SSRC is an excellent way to introduce general surgery residents to robotics. This study shows that with attending supervision, SSRC is feasible and safe for both junior and senior residents with very low complication rates and no adverse effect on operative time.

RESUMO

OBJECTIVE: The purpose of this study was to evaluate the safety and performance of localizing nonpalpable breast lesions using radiofrequency identification technology. SUBJECTS AND METHODS: Twenty consecutive women requiring preoperative localization of a breast lesion were recruited. Subjects underwent placement of both a hook wire and a radiofrequency identification tag immediately before surgery. The radiofrequency identification tag was the primary method used by the operating surgeon to localize each lesion during excision, with the hook wire serving as backup in case of tag migration or failed localization. Successful localization with removal of the intended lesion was the primary outcome measured. Tag migration and postoperative infection were also noted to assess safety. RESULTS: Twenty patients underwent placement of a radiofrequency identification tag, 12 under ultrasound guidance and eight with stereotactic guidance. In all cases, the radiofrequency identification tag was successfully localized by the reader at the level of the skin before incision, and the intended lesion was removed along with the radiofrequency identification tag. There were no localization failures and no postoperative infections. Tag migration did not occur before incision, but in three cases, occurred as the lesion was being retracted with fingers to make the final cut along the deep surface of the specimen. CONCLUSION: In this initial clinical study, radiofrequency tags were safe and able to successfully localize nonpalpable breast lesions. Radiofrequency identification technology may represent an alternative method to hook wire localization.

RESUMO

BACKGROUND: The current mainstay of lymphedema therapy has been conservative nonsurgical treatment. However, surgical options for lymphedema have been reported for over a century. Early surgical procedures were often invasive and disfiguring, and they often had only limited long-term success. In contrast, contemporary surgical techniques are much less invasive and have been shown to be effective in reducing excess limb volume, the risk of cellulitis, and the need for compression garment use and lymphedema therapy. Microsurgical procedures such as lymphaticovenous anastomosis and vascularized lymph node transfer lymphaticolymphatic bypass can treat the excess fluid component of lymphedema swelling that presents as pitting edema. Suction-assisted protein lipectomy is a minimally invasive procedure that addresses the solid component of lymphedema swelling that typically occurs later in the disease process and presents as chronic nonpitting lymphedema. These surgical techniques are becoming increasingly popular and their success continues to be documented in the medical literature. We review the efficacy and limitations of these contemporary surgical procedures for lymphedema. METHODS: A Medline literature review was performed of lymphedema surgery, vascularized lymph node transfer, lymphaticovenous anastomosis, lymphatic liposuction, and lymphaticolymphatic bypass with particular emphasis on developments within the past 10 years. A literature review of technique, indications, and outcomes of the surgical treatments for lymphedema was undertaken. RESULTS: Surgical treatments have evolved to become less invasive and more effective. CONCLUSIONS: With proper diagnosis and the appropriate selection of procedure, surgical techniques can be used to treat lymphedema safely and effectively in many patients when combined with integrated lymphedema therapy.

RESUMO

BACKGROUND: Effective surgical treatments for lymphedema now can address the fluid and solid phases of the disease process. Microsurgical procedures, including lymphaticovenous anastomosis (LVA) and vascularized lymph node transfer (VLNT), target the fluid component that predominates at earlier stages of the disease. Suction-assisted protein lipectomy (SAPL) addresses the solid component that typically presents later as chronic, nonpitting lymphedema of an extremity. We assess the outcomes of patients who underwent selective application of these three surgical procedures as part of an effective system to treat lymphedema. METHODS: This is a retrospective chart review of patients with lymphedema who underwent complete decongestive therapy followed by surgical treatment with SAPL, LVA, or VLNT. The primary outcomes measured were postoperative volume reduction (SAPL), daily requirement for compression garments and lymphedema therapy (VLNT and LVA), and the incidence of severe cellulitis. RESULTS: Twenty-six patients were included in the study, of which 10 underwent SAPL and 16 underwent LVA or VLNT. The average reduction of excess volume by SAPL was 3,212 mL in legs and 943 mL in arms, or a volume reduction of 87 and 111 %, respectively, when compared with the unaffected, opposite sides. Microsurgical procedures (VLNT and LVA) significantly reduced the need for both compression garment use (p = 0.003) and lymphedema therapy (p < 0.0001). The overall rate of cellulitis decreased from 58 % before surgery to 15 % after surgery (p < 0.0001). CONCLUSIONS: When applied appropriately to properly selected patients, surgical procedures used in the treatment of lymphedema are effective and safe.

RESUMO

Surgical treatment of chronic lymphedema has seen significant advances. Suction-assisted protein lipectomy (SAPL) has been shown to safely and effectively reduce the solid component of swelling in chronic lymphedema. However, these patients must continuously use compression garments to control and prevent recurrence. Microsurgery procedures, including lymphaticovenous anastomosis (LVA) and vascularized lymph node transfer (VLNT), have been shown to be effective in the management of the fluid component of lymphedema and allow for decreased garment use. SAPL and VLNT were applied together in a two-stage approach in two patients with chronic lymphedema after treatment for breast cancer. SAPL was used first to remove the chronic, solid component of the soft-tissue excess. Volume excess in our patients' arms was reduced an average of approximately 83% and 110% after SAPL surgery. After the arms had sufficiently healed and the volume reductions had stabilized, VLNT was performed to reduce the need for continuous compression and reduce fluid re-accumulation. Following the VLNT procedures, the patients were able to remove their compression garments consistently during the day and still maintain their volume reductions. Neither patient had any postoperative episodes of cellulitis. SAPL and VLNT can be combined to achieve optimal outcomes in patients with chronic lymphedema.

RESUMO

BACKGROUND: Breast reconstruction (BR) has documented psychological benefits following mastectomy. Yet, racial/ethnic minority groups have lower reported rates of BR. We sought to evaluate the rate, type, and outcome of BR in a racially and ethnically diverse population within a safety-net hospital system. METHODS: All patients who underwent mastectomy between October 2015 and July 2019 at Harbor-UCLA Medical Center were retrospectively examined. Rates and type of BR were analyzed according to patient characteristics (race/ethnicity, age, and body mass index), smoking status, cancer stage, and presence of diabetes mellitus. Breast reconstruction outcomes were also assessed. RESULTS: Of the 259 patients that underwent mastectomy, 87 (33.6%) received BR. Immediate BR was performed in 79 (30.5%) patients and delayed BR in 8 (3.1%). Of the 79 patients with immediate BR, 58 (73.4%) received implant-based BR and 21 (26.5%) autologous tissue. The BR failure rate was 10%, all implant-based. Increasing age and smoking negatively impacted BR rates. Black (P =.331) and Hispanic (P =.132) ethnicity were not independent predictors of decreased breast reconstruction. CONCLUSION: This study demonstrated that the rate, type, and quality of BR in this integrated safety-net hospital within a diverse population are comparable to national rates. When made available, historically underrepresented minority patients of Black and Hispanic ethnicity utilize BR.

RESUMO

OBJECTIVE: Robotic-assisted surgery (RAS) accounts for 15% of general surgery (GS) operations performed and is set to grow in prevalence. Currently, there are no training requirements or standard robotic curricula for GS residents. This study aimed to query GS program directors (PDs) on the necessity, extent, and potential impact of including RAS as a required component of residency training. DESIGN: Analysis of responses to a 14-question web-based survey. SETTING: Survey was distributed to PDs via the Association of Program Directors in Surgery listserv in April and May 2021. PARTICIPANTS: General surgery program directors RESULTS: Among 140 respondents, 110 (78.6%) agreed that operating at the robotic console should be a GS residency requirement, yet 93 (66.4%) indicated that RAS exposure negatively impacts the acquisition of other necessary skills. Still, 116 (82.9%) agreed that RAS training provided a net benefit to GS residents, PDs at academic programs were more supportive than those at independent programs of RAS console training requirements (68.2% versus 46.7%, p = 0.048). The median response to the ideal proportion of abdominopelvic cases performed by graduation was 20% robotic, 40% laparoscopic, and 35% open. The suggested minimum number of robotic cases that should be performed by graduation was indicated to be 30 cases by 26% of respondents, 20 by 23%, 10 by 12%, 5 by 4%, and "no minimum" by 36%. CONCLUSIONS: There is strong interest among PDs to institute RAS training requirements for GS residents. This study provides PD perspectives to help inform national conversations on whether and to what extent RAS requirements should be included in GS residency training.

RESUMO

Nipple adenoma is a rare proliferative lesion that originates from the lactiferous ducts of the nipple. Though it is benign, the typical presentation includes suspicious symptoms-a firm nodule, crusting erosion, and/or discharge from the nipple. These findings can raise concern for malignancy and in particular, Paget's disease. We report two cases of this uncommon entity, highlighting the variable clinical presentation and keys to the diagnostic evaluation and management.

RESUMO

INTRODUCTION: Psychosocial distress screening of cancer patients is an American College of Surgeons Commission on Cancer mandate for accredited cancer programs. We evaluated psychosocial distress in breast cancer patients to characterize risk factors for high distress scores at a safety net hospital. MATERIALS AND METHODS: The psychosocial distress screening form includes a list of potential issues and a distress score scaled from 1 through 10. Psychosocial distress screening results were retrospectively analyzed, along with patient demographics and clinical data. Cochran-Mantel-Haenszel test was applied to identify predictors for high distress scores, which were defined as a score of 5 and greater. RESULTS: 775 distress screens were completed by 171 breast cancer patients. High distress scores were reported in 21.3%. Patients who had no evidence of disease at time of screening were less likely to report a high distress score compared to those who were newly diagnosed or in active treatment (odds ratio 0.51, 95% CI, 0.38-0.68, P< .0001). Patients with high distress scores were more likely to report concerns with insurance (29.1% vs. 7.6%, P< .0001), transportation (16.4% vs. 4.6%, P< .0001), housing (15.2% vs 2.1%, P< .0001), sadness/depression (63.6% vs. 14.1, P< .0001), and physical issues (89.1% vs. 52.8%, P< .0001). CONCLUSION: Status of cancer at time of screening, particularly newly diagnosed cancer and active treatment of cancer were associated with high distress scores in this patient group. While there should be an emphasis to ensure patients with these risk factors receive psychosocial distress screening, routine periodic screening for all patients should continue to be implemented to ensure quality cancer care.
