RESUMO

BACKGROUND: Undifferentiated carcinoma of the pancreas (UPC) is a rare malignancy. There are no standardized guidelines for treatment. Current management has been extrapolated from smaller reviews. METHODS: 858 patients with UPC were identified in the 2004-2017 NCDB. Kaplan-Meier method followed by Cox proportional-hazards regression examined independent prognostic factors associated with overall survival (OS). Logistic regression analyses were performed to determine independent predictors of surgical intervention and the status of surgical resection by histologic subtype. RESULTS: Patients with osteoclast-like giant cells (OCLGC) had a longer median OS compared to those without (aHR 0.52: 95% CI 0.41-0.67). Of the non-OCLGC subtypes, pleomorphic large cell demonstrated the shortest median OS (2.4 months). Surgical resection was associated with improved survival in all histologies except for pleomorphic cell carcinoma. R0 resection and negative lymph nodes were independently associated with an improved OS. CONCLUSION: This is the largest database review published to date on UCP. OCLGC histology is associated with an improved survival compared to those without OCLGC. Of the non-OCLGC subtypes, pleomorphic large cell is associated with the shortest overall survival. Surgical resection is associated with a significant survival advantage for all histologies except for pleomorphic cell carcinoma.

RESUMO

BACKGROUND: Although the incidence and mortality have decreased, gastric cancer (GC) is still a public health issue globally. An international study reported higher survival in Korea and Japan than other countries, including the United States. We examined the determinant factors of the high survival in Japan compared with the United States. METHODS: We analysed data on 78,648 cases from the nationwide GC registration project, the Japanese Gastric Cancer Association (JGCA), from 2004-2007 and compared them with 16,722 cases from the Surveillance, Epidemiology, and End Results Program (SEER), a United States population-based cancer registry data from 2004-2010. We estimated 5-year relative survival and applied a multivariate excess hazard model to compare the two countries, considering the effect of number of lymph nodes (LNs) examined. RESULTS: Five-year relative survival in Japan was 81.0%, compared with 45.0% in the United States. After controlling for confounding factors, we still observed significantly higher survival in Japan. Among N2 patients, a higher number of LNs examined showed better survival in both countries. Among N3 patients, the relationship between number of LNs examined and differences in survival between the two countries disappeared. CONCLUSION: Although the wide differences in GC survival between Japan and United States can be largely explained by differences in the stage at diagnosis, the number of LNs examined may also help to explain the gaps between two countries, which is related to stage migration.

RESUMO

BACKGROUND: For patients with pancreatic adenocarcinoma (PA), the optimal time interval between neoadjuvant chemoradiation (CR) to surgical resection has not been well established. METHODS: The National Cancer Database from 2006 to 2014 was queried for patients ≥18 y old diagnosed with PA who received neoadjuvant CR. Survival and short-term outcomes were compared between patients who had pancreaticoduodenectomy ≤12 wk and >12 wk after completion of CR. RESULTS: 1610 patients met selection criteria. Average radiation to surgery (RS) interval was 58.2 ± 39.5 d. 1419 patients had RS interval ≤12 wk (mean 47.4 d) and 191 had RS interval >12 wk (mean 138.8 d). Demographics, CA 19-9 levels, types of chemotherapy and radiation dosage were similar between the two groups. There were more patients with clinical stage III cancers in the >12 wk group than in the ≤12 wk group (33.5% versus 14%). Short-term outcomes were similar between the two groups. However, a long-term survival benefit was observed in the >12 wk group (median 25.8 versus 30.2 mo P = 0.049). An interval >12 wk was associated with significantly prolonged survival on multivariate analysis (HR: 0.80, 95% CI: 0.65-0.99; P = 0.042). Higher clinical stage and positive surgical margins were independently associated with worse survival. CONCLUSIONS: Surgical resection beyond 12 wk after CR for PA did not worsen short-term outcomes. Waiting may contribute to better patient selection, especially those with locally advanced tumors. In the absence of progressive disease, patients need to be continuously evaluated for surgical resection after CR.

RESUMO

BACKGROUND: With reductions in public funding, alternate research funding is essential to surgical oncologists (SOs). We aimed to examine current trends in industry funding of SOs. METHODS: Society of Surgical Oncology surgeons were identified and matched with board certification and years in practice. Departmental and hospital data were evaluated, and industry payments from 2013 to 2017 were matched with the Open Payment Data. RESULTS: Of the 1670 SOs identified, 922 (55%) had academic positions: 588 (64%) males and 334 (36%) females. Between 2013 and 2017, research payments totaling $46,596,706 were made to 162 SOs (17.5%): $40,774,716 (87%) for research related to drugs and clinical trials, compared with $5,194,199 (11%) for surgical devices (p = 0.018). Funding correlated with academic leadership and years in practice (p = 0.0001 and p = 0.0037). Massachusetts ($9,060,976), Texas ($7,656,228), and New York ($4,210,864) received the most funding, whereas Utah ($1,533,166/SO), Massachusetts ($1,294,425/SO), and Oregon ($1,241,702/SO) received the highest average payments per SO. The majority of funding was from Novartis ($16,045,608), Amgen ($6,810,832), and Merck ($3,758,299), for an oncolytic vaccine (talimogene laherparepvec, $5,939,007), a BRAF inhibitor (dabrafenib, $5,727,309), and a KIT inhibitor (imatinib, $4,323,586). Male SOs received funding more frequently than females (120/588 [20%] vs. 42/334 [12.6%]; p = 0.0027). Males also received more general payments (travel/lodging, food/beverage, consulting/speaker fees): $48,830 vs. $11,867 per male and female, respectively (p = 0.0001). CONCLUSIONS: The majority of industry research payments to SOs are related to novel pharmaceuticals, which highlights the expanding influence SOs play in systemic therapies. Industry payments are influenced by location, gender, and academic leadership.

RESUMO

BACKGROUND: Although resection historically played a prominent role in the treatment of metastatic melanoma, recent advances have altered the therapeutic landscape, and potentially the role of surgery. We examined surgical selection and metastasectomy outcomes before and after the onset of the effective drug therapy era. METHODS: Patients with stage IV melanoma were identified and characterized by treatment era (either 1965-2007 or 2008-2015) and by systemic therapy agents. BRAF and/or MEK inhibitors, as well as checkpoint inhibitors, were included as modern agents. Selection factors for metastasectomy were examined by era. A matched-pair analysis of outcomes of surgical and non-surgical patients receiving modern systemic agents was performed. RESULTS: Among 2353 eligible patients, 1065 (45.2%) underwent surgical treatment. Factors associated with selection for metastasectomy in the early era included female sex, no prior stage III disease, single-organ involvement, and M1a (vs. M1c) disease (all p < 0.007). In the current era, the proportion of surgically treated patients increased modestly (54.5% vs. 44.7%, p = 0.02) and age was the only independent selection factor (p < 0.01). Surgery followed by modern therapy in 47 matched pairs was associated with higher 5-year melanoma-specific survival (MSS) versus modern therapy alone (58.8% vs. 38.9%, p = 0.049). Multivariable regression showed single-organ involvement (hazard ratio [HR] 0.43, 95% confidence interval [CI] 0.21-0.90, p = 0.02) and first-line surgery (HR 0.47, 95% CI 0.23-0.98, p = 0.04), as well as use of modern agents (HR 0.29, 95% CI 0.21-0.40, p < 0.001), were independently associated with improved MSS. CONCLUSIONS AND RELEVANCE: While modern systemic agents have improved outcomes in stage IV melanoma, metastasectomy remains associated with favorable survival. Resection remains a viable therapeutic approach, possibly worthy of prospective evaluation.

RESUMO

BACKGROUND: Pancreatic surgery outcomes are associated with surgeon and center experience. Anesthesiologists as potential value drivers for pancreatic surgery have not been explored. We sought to evaluate whether anesthesiologists impact perioperative costs for pancreatic surgery. METHODS: Within an integrated health care system, 796 pancreatic surgeries (526 PDs and 270 DPs) were performed from January 2014 to June 2017. Mean direct operative and anesthesia costs driven by anesthesiologists (operating room (OR) time, anesthesia billing and anesthesia procedures) were determined for each case. The volumes of pancreatic cases per anesthesiologist were calculated, and those above the 75th percentile for volume (4 cases) were considered high-volume. A multivariable analysis of OR/anesthesia costs was performed. RESULTS: Mean OR and anesthesia costs for PD were $7064 for low-volume anesthesiologists (LVA), higher than $5968 for high-volume anesthesiologists (HVA) (p < 0.001). By multivariable analysis, HVA were associated with decreased costs of $2278 (p < 0.001). Teams of HVA and high-volume surgeons (HVS) were also associated with decreased mean costs of $1790 (p = 0.04). CONCLUSION: These data suggest that anesthesiologists experienced in the management of complex pancreatic operations such as PDs may contribute to improved efficiencies in care by reducing perioperative costs.

RESUMO

BACKGROUND: The association between tumor mismatch repair status and obesity in colon cancer is not well understood. The authors of this study hypothesized that mismatch repair deficiency in colon cancer may be associated with a lower Body Mass Index (BMI) and improved patient outcome due to an enhanced tumor immune microenvironment. METHODS: For this study, 70 patients were randomly selected from a prospective trial evaluating nodal ultrastaging for colon cancer. The mismatch repair status of tumors and immunomarker expression were correlated with clinicopathologic characteristics and evaluated for disease-free survival. RESULTS: Patients with mismatch repair-deficient tumors (n = 11) had a lower mean BMI than those with mismatch repair-proficient tumors (n = 59) (22.16 vs. 26.30 kg/m2, respectively; p = 0.029).The findings showed that CD3+ T cells were inversely associated with mismatch repair proficiency (p = 0.048). Mismatch repair-proficient tumors in nonobese patients (BMI < 30 kg/m2) versus obese patients had a higher density of CD8+ (p = 0.008) and FOXP3+ (p = 0.005) T cells. Multivariable analysis linked CD4+ (hazard ratio [HR] 0.52; 95% confidence interval [CI] 0.35-0.76), CD8+ (HR 0.67; 95% CI 0.50-0.89), and number of tumor-positive lymph nodes (HR 1.19; 95% CI 1.03-1.36) to disease-free survival for patients with mismatch repair-proficient tumors. CONCLUSIONS: Tumor mismatch repair status and obesity are correlated in patients with colon cancer. Increased intratumoral T cells in nonobese patients suggests an unexplored link between tumor mismatch repair and immunoprofile.

RESUMO

INTRODUCTION: Stage II-III rectal cancer requires multidisciplinary cancer care, and adolescents and young adults (AYA, ages 15-39 years) often do not receive optimal cancer therapy. METHODS: Overall, 3295 AYAs with clinical stage II-III rectal cancer were identified in the National Cancer Database. Factors associated with the receipt of adjuvant and surgical therapies, as well as overall survival (OS), were examined. RESULTS: The majority of patients were non-Hispanic White (72.0 %), male (57.5 %), and without comorbidities (93.8 %). A greater proportion of Black and Hispanic patients did not receive radiation (24.5 and 27.1 %, respectively, vs. 16.5 % for non-Hispanic White patients), surgery (22.4 % and 21.6 vs. 12.3 %), or chemotherapy (21.5 % and 24.1 vs. 14.7 %) compared with non-Hispanic White patients (all p < 0.05). After controlling for competing factors, Black (odds ratio [OR] 0.7, 95 % confidence interval [CI] 0.5-0.9) and Hispanic patients (OR 0.6, 95 % CI 0.4-0.9) were less likely to receive neoadjuvant chemoradiation compared with non-Hispanic White patients. Females, the uninsured, and those treated at a community cancer center were also less likely to receive neoadjuvant therapy. Having government insurance (OR 0.22, 95 % CI 010-0.49) was a predictor for not receiving surgery. Although 5-year OS was lower (p < 0.05) in Black (59.8 %) and Hispanic patients (65.9 %) compared with non-Hispanic White patients (74.9 %), on multivariate analysis race did not impact mortality. Not having surgery (hazard ratio [HR] 7.1, 95 % CI 2.8-18.2) had the greatest influence on mortality, followed by poorly differentiated histology (HR 3.0, 95 % CI 1.3-6.5), nodal positivity (HR 2.6, 95 % CI 1.9-3.6), no chemotherapy (HR 1.9, 95 % CI 1.03-3.6), no insurance (HR 1.7, 95 % CI 1.1-2.7), and male sex (HR 1.5, 95 % CI 1.1-2.0). CONCLUSION: There are racial and socioeconomic disparities in the treatment of stage II-III rectal cancer in AYAs, many of which impact OS. Interventions that can address and mitigate these differences may lead to improvements in OS for some patients.

RESUMO

BACKGROUND: Studies on perioperative outcomes of octogenarians with gastric cancer are limited by small sample size. Our aim was to determine the outcomes of gastrectomy and the variation of treatments associated with advanced age (≥80 y). METHODS: The National Surgical Quality Improvement Program database was queried from 2005 to 2011. Patients who underwent gastrectomy for malignancy were identified using International Classification of Diseases, Ninth Revision and Current Procedural Terminology codes. RESULTS: Of 2591 cases, 487 patients were octogenarians (≥80) and 2104 were nonoctogenarians (<80). Overall, 4.9% of patients had disseminated cancer. Octogenarians had higher 30-d mortality (7.2% versus 2.5%, P < 0.01) and more major complications (31.4% versus 25.5%, P < 0.01), though fewer octogenarians underwent total gastrectomy (24.0% versus 43.2%, P < 0.01) and extended lymphadenectomy (10.1% versus 17.4%, P < 0.01) than the nonoctogenarian cohort. On multivariate analysis, age ≥80 y was associated with major complications (OR, 1.3; 95% CI, 1.03-1.6; P = 0.03) and increased mortality (OR, 3.0; 95% CI, 1.9-4.9; P < 0.01). CONCLUSIONS: Advanced age (≥80 y) was associated with worse outcomes in patients undergoing gastrectomy for malignancy. Therefore, careful staging is necessary to reduce unnecessary operations in this population. Furthermore, surgeons must place greater attention on optimizing the octogenarian population before surgery.

RESUMO

BACKGROUND: Various mechanisms, including somatic and visceral nociceptive stimulation, have been suggested as a cause for pain after laparoscopic cholecystectomy (LC). We therefore conducted a prospective randomized controlled trial (PRCT) to evaluate whether somatovisceral pain blockade reduces pain after LC. HYPOTHESIS: Analgesic efficacy of multimodal analgesia is superior to standard analgesia for patients undergoing elective LC for symptomatic cholelithiasis. Specifically, topical cystic plate and port-site injection with 0.25 % bupivacaine significantly reduces pain after LC. DESIGN: This study was designed as single-blinded PRCT. SETTING: This study was conducted in an academic medical center. PATIENTS AND METHODS: Between February and May 2010 we randomly assigned 63 patients with symptomatic cholelithiasis in a 1:1 ratio to non-opioid/opioid analgesic combinations (Control Group, n = 32) and non-opioid/opioid analgesic combinations plus topical 0.25 % bupivacaine onto the cystic plate and local 0.25 % bupivacaine port-site injection, post-LC (Study Group, n = 31). Primary endpoint was patient-reported pain 1, 4, 6, 12, 24 h and 1 week post-LC using the Visual Analog Scale (VAS 0-10). RESULTS: Study groups were comparable clinicopathologically. There were no adverse events. A statistically significant reduction in mean pain score was apparent in Study Group patients in comparison with Control Group (mean VAS 4.83 ± 2.33 vs. 6.80 ± 1.87; p < 0.001) at all early (1-6 h) post-operative time points following LC. CONCLUSION: This PRCT shows significantly improved pain control with somatovisceral pain blockade over non-opioid/opioid analgesic combinations following LC for symptomatic cholelithiasis. For centers not utilizing adjunctive local anesthetic for LC, this topical use of bupivacaine may improve patient comfort during recovery. This trial was registered on www.ClinicalTrials.gov NCT# 01972620.

RESUMO

BACKGROUND: The incidence of colorectal cancer (CRC) in the adolescent and young adult (AYA) population (aged 15-39 y) is rising. MATERIALS AND METHODS: We used the Surveillance, Epidemiology, and End Results Database to study CRC in the AYA population. We studied clinical and socioeconomic factors associated with survival. RESULTS: Of the 11,071 cases of CRC, the most common site of the primary tumor was the rectum (25%), whereas 66.6% of the diseases were left sided. Most of the patients (72%) presented with regional or metastatic disease. However, the disease-specific survival (DSS) and the overall survival of the AYA population were comparable to those of the general population (DSS; 5- and 10-y: 64.8%, 57.3%; overall survival; 5- and 10-y: 61.5% and 52.4%). On multivariate analysis, disease stage at the time of the diagnosis was the strongest predictor of mortality. After controlling for disease stage, male gender, black race, and higher grade tumors were associated with worse survival. CONCLUSIONS: The AYA population presents with advanced distal CRC but have similar survival compared with the general population.

RESUMO

BACKGROUND: The staging of gastric cancer has become increasingly complex. With an emerging 15-node quality measure and a revised American Joint Committee on Cancer (AJCC) staging system, we evaluated the need for more intricate staging systems to predict survival outcomes in gastric cancer. METHODS: The Surveillance, Epidemiology and End Results Program (SEER) database was used to identify 124,972 patients with gastric cancer between 2000 and 2010. Primary endpoints were 5-year disease-specific survival (DSS) and overall survival (OS). Analysis was performed on patients with ≥15 nodes evaluated. Multivariable regression with/without the inclusion of lymph node (LN) assessment and LN ratio were compared using the Akaike information criterion. RESULTS: The number of patients included in the final analysis was 12,096. The proportion of patients with an adequate lymphadenectomy increased markedly from 27 % in 2000 to 52 % in 2010. Overall 5-year DSS and OS was 61.9 and 48.8 %, respectively, for patients with ≥15 nodes examined, versus 57.7 and 39.9 %, respectively, for those with <15 sampled nodes (p < 0.0001). In patients with ≥15 nodes evaluated, the addition of LN evaluation and LN ratio to the existing staging model improved its ability to predict 5-year DSS and OS (p < 0.0001). LN evaluation and LN ratio were comparable in their ability to supplement the existing AJCC 7th edition (AJCC7) staging system. CONCLUSION: The inclusion of a minimum 15-LN quality measure improves the prognostic ability of the AJCC7 staging system, without adding significant complexity.

RESUMO

BACKGROUND: The purpose of this study was to determine if gene signatures are informative in colon cancer (CC) when National Quality Standards (NQS) are adhered to. Several studies have demonstrated the prognostic potential of gene signatures in primary CC. This has never been evaluated prospectively with adherence to NQS. METHODS: This was a prospective, international, multicenter trial. Eligibility criteria were: no distant metastasis, ≥12 lymph nodes (LNs), and no adjuvant chemotherapy for LN-negative CC. RNA from frozen tumor samples was considered reliable if RNA Integrity Number >9. Using an Agilent whole human genome array, 44,000 genes were analyzed in primary tumors for differential gene expression (DGE). ANOVA applied at 2-fold expression level was performed in at least 8 experiments to obtain the DGEs. RESULTS: Molecular analysis was completed in 113 of 128 patients. With median follow-up of 27 months, 11.5 % recurred within 3 years after surgery. Significant DGE was identified in recurrent tumors reflected by upregulation (UR) in cellular proliferation and by downregulation (DR) in prodifferentiating panel of 9 genes, independent of T or N classification. By multivariate analysis 3-year disease-free survival was 12.5 % in the UR/DR group versus 93.4 % in the non-UR/DR group (p < .0001; HR = 24.2; 95 % CI 4.8-120.4). CONCLUSIONS: This is the first prospective trial to evaluate gene signatures in CC with adherence to a 12-node minimum quality standard. Certain molecular pathways may be prognostically relevant if both surgery and pathology are standardized, regardless of T or N classification. Careful consideration should be made to include surgical quality measures when planning clinical trials to evaluate the true effect of molecular markers in CC.

RESUMO

BACKGROUND: With the first qualifying examination administered September 15, 2014, complex general surgical oncology (CGSO) is now a board-certified specialty. We aimed to assess the attitudes and perceptions of current and future surgical oncology fellows regarding the recently instituted Accreditation Council for Graduate Medical Education (ACGME) accreditation. METHODS: A 29-question anonymous survey was distributed to fellows in surgical oncology fellowship programs and applicants interviewing at our fellowship program. RESULTS: There were 110 responses (79 fellows and 31 candidates). The response rate for the first- and second-year fellows was 66 %. Ninety-percent of the respondents were aware that completing an ACGME-accredited fellowship leads to board eligibility in CGSO. However, the majority (80 %) of the respondents stated that their decision to specialize in surgical oncology was not influenced by the ACGME accreditation. The fellows in training were concerned about the cost of the exam (90 %) and expressed anxiety in preparing for another board exam (83 %). However, the majority of the respondents believed that CGSO board certification will be helpful (79 %) in obtaining their future career goals. Interestingly, candidate fellows appeared more focused on a career in general complex surgical oncology (p = 0.004), highlighting the impact that fellowship training may have on organ-specific subspecialization. CONCLUSIONS: The majority of the surveyed surgical oncology fellows and candidates believe that obtaining board certification in CGSO is important and will help them pursue their career goals. However, the decision to specialize in surgical oncology does not appear to be motivated by ACGME accreditation or the new board certification.

RESUMO

BACKGROUND: Bundled Payment (BP) models are becoming more common in surgery. We share our early experiences with Bundled Payments for Care Improvement for major bowel surgery. METHODS: Patients undergoing major bowel surgery between January and October 2021 were identified using Medicare Severity-Diagnosis Related Group (MS-DRG) codes. Major drivers of cost in a BP model are reported and compared to the Fee-For-Service (FFS) payment model. RESULTS: A total of 202 cases (173 FFS vs 29 BP) were analyzed. The mean BP cost per Clinical Episode was $28,340. Eleven patients (38%) in the BP model had costs greater than the Target Price. The drivers of cost in the BP model were 59% acute care facility, 17% physician services, 9% post-acute care facilities, 8% other, and 7% readmissions. Clinical Episode of care costs varied considerably by MS-DRG case complexity. Robotic surgery increased costs by 35% (mean increase $3724, P < .01). The 90-day readmission rate was 17% for a mean cost of $11,332 per readmission. Three patients (10%) were discharged to a skilled nursing facility at an average cost of $11,009, while fifteen patients (52%) received home health services at a mean cost of $2947. Acute care facility costs were similar in the BP vs FFS groups (mean difference $1333, P = .22). CONCLUSIONS: Patients undergoing major bowel surgery are a heterogeneous population. Physicians are ideally positioned to deliver high-value, patient-centered care and are crucial to the success of a BP model. The post-acute care setting is a key component of improving efficiency and quality of care.

RESUMO

BACKGROUND: Medicare expenditures have steadily increased over the decades, and yet Medicare Physician Fee Schedule payments for individual services have declined. We examine trends in Medicare Physician Fee Schedule payments for office visits, inpatient visits, and surgical procedures. METHODS: The Medicare Physician Fee Schedule Look-Up Tool was queried for payment data for office visits, inpatient visits, and surgical procedures between 2013 and 2023. All data were adjusted for inflation using the Consumer Price Index. Trends in payments were calculated for 5 common procedures in each surgical specialty. Trends in aggregate national health expenditures were compared to Medicare Physician Fee Schedule payments for physician services from 2013 to 2021. RESULTS: The Consumer Price Index increased by 29.3% from 2013 to 2023. Inflation-adjusted per-visit Medicare Physician Fee Schedule payments decreased by 12.2% for outpatient office visits, 19.1% for inpatient visits, and 22.8% for surgical procedures from 2013 to 2023. This varied by surgical specialty: vascular (-25.8%), endocrine (-22.0%), general surgery (-27.0%), thoracic (-19.2%), surgical oncology (-22.1%), breast (-22.4%), urology (-2.2%), neurosurgery (-22.8%), obstetrics/gynecology (-19.9%), and orthopedics (-24.7%). Adjusted for inflation, national health expenditures increased by 33.9% for physician services from 2013 to 2021. In comparison, Medicare Physician Fee Schedule payments over the same time period 2013 to 2021 increased by 1.3% for outpatient office visits but decreased by 10.6% for inpatient visits and 9.8% for surgical procedures. CONCLUSION: Controlling rising national health expenditures is important and necessary, but 10 years of declining Medicare Physician Fee Schedule payments on a per-procedure basis in surgery would suggest that this strategy alone may not achieve those goals and could ultimately threaten access to quality surgical care. Surgeons must advocate for permanent payment reforms.

RESUMO

BACKGROUND: A practice standard in sentinel lymph node (SLN) mapping in breast cancer is intradermal injection of technetium-99m sulfur colloid (Tc-99m), resulting in significant patient discomfort and pain. A previous randomized controlled trial showed that adding lidocaine to Tc-99m significantly reduced radioisotope injection-related pain. We tested whether 1 % lidocaine admixed with Tc-99m affects feasibility of SLN mapping. METHODS: Between January 2006 and April 2009, 140 patients with early breast cancer were randomly assigned (1:1:1:1) to receive standard topical 4 % lidocaine cream and intradermal Tc-99m (control) or to one of three other study groups: topical placebo cream and injection of Tc-99m containing sodium bicarbonate (NaHCO3), 1 % lidocaine, or both. All SLN data were collected prospectively. RESULTS: Study groups were comparable for clinicopathological parameters. As previously reported, the addition of 1 % lidocaine to the radioisotope solution significantly improved patient comfort. Overall SLN identification rate in the trial was 93 %. Technical aspects of SLN biopsy were similar for all groups, including time from injection to operation, first SLN (SLN 1) gamma probe counts, ex vivo counts for SLN 1 and SLN 2, and axillary bed counts. SLN identification rates were comparable statistically: control (96 %), lidocaine (90 %), sodium bicarbonate (97 %), and sodium bicarbonate-lidocaine (90 %). The control group had a significantly higher SLN 2/SLN 1 ex vivo count ratio, and the number of SLNs detected was significantly reduced in the lidocaine versus no-lidocaine groups (p < 0.05). CONCLUSIONS: Addition of 1 % lidocaine to standard radioisotope solution for SLN mapping in breast cancer is associated with fewer SLNs detected, but it does not appear to compromise SLN identification.
