Abstract
PURPOSE This study aimed to validate the classification of breast cancer (BC) patients in progression risk groups based on total tumor load (TTL) value to predict lymph node (LN) affectation after neo-adjuvant systemic therapy (NAST) obtained in the NEOVATTL study. METHODS/PATIENTS This was an observational, retrospective, international, multicenter study including patients with infiltrating BC who received NAST followed by sentinel lymph node biopsy (SLNB) analyzed with one-step nucleic acid amplification (OSNA) from nine Spanish and two Italian hospitals. Patients were classified into three groups according to the progression risk, measured as disease-free survival (DFS), based on TTL values (> 250, 250-25,000, and > 25,000 copies/μL). The previous (NEOVATTL study) Cox regression model for prognosis was validated using prognostic index (PI) and Log ratio test (LRT) analyses; the value of TTL for axillary non-SLN affectation was assessed using receiver operating characteristic (ROC) curves. RESULTS We included 263 patients with a mean age of 51.4 (± SD 10.5) years. Patients with TTL > 25,000 copies/μL had a shorter DFS (HR 3.561 [95% CI 1.693-7.489], p = 0.0008 vs. TTL ≤ 25,000). PI and LRT analyses showed no differences between the two cohorts (p = 0.2553 and p = 0.226, respectively). ROC analysis showed concordance between TTL and non-SLN involvement (area under the curve 0.828), with 95.7% sensitivity and 92.9% specificity at a TTL cut-off of > 15,000 copies/μL. CONCLUSIONS In BC patients who had received NAST and underwent SLNB analysis using OSNA, a TTL value of > 25,000 copies/μL was associated with a higher progression risk and > 15,000 copies/μL was predictive of non-SLN involvement.

Open Med (Wars) 2023; 18:20230827. [PMID: 38025542 PMCID: PMC10655687 DOI: 10.1515/med-2023-0827] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2022] [Revised: 05/09/2023] [Accepted: 10/03/2023] [Indexed: 12/01/2023] Open
Abstract
This meta-analysis aimed to evaluate the diagnostic accuracy of touch imprint cytology (TIC) for sentinel lymph node (SLN) metastases of patients with clinical node-negative early breast cancer. The PubMed, Web of Science, Embase, and the Cochrane Library databases were meticulously searched to retrieve literature published from January 2005 to September 2022 by two independent reviewers. The meta-analysis was performed using STATA16.0, Meta-Disc 1.4, and RevMan 5.4.9. According to the inclusion criteria, 4,073 patients from 13 studies were included in this meta-analysis. The pooled sensitivity and specificity of TIC for detecting SLN metastases were 0.77 (95% CI 0.66-0.85) and 0.99 (95% CI 0.97-1.00), respectively. The pooled positive likelihood ratio and negative likelihood ratio were 76.15 (95% CI 29.16-198.84) and 0.23 (95% CI 0.15-0.36), respectively. The pooled diagnostic odds ratio was 326.82 (95% CI 132.76-804.56) and the area under the sROC curve was 0.97 (95% CI 0.95-0.98), respectively. This meta-analysis revealed that TIC with high sensitivity and specificity is a feasibility and accuracy diagnosis technique for intraoperative detection of SLN metastases in breast cancer.

Abstract
INTRODUCTION Evaluation of axillary lymph nodes after sentinel lymph node biopsy (SLNB) in breast cancer is mostly done by intra-operative frozen section biopsy (FSB) and/ or touch imprint cytology (TIC). In this systematic review and meta-analysis, we have compared the accuracy of the two modalities. METHODS PubMed, EMBASE, and Cochrane electronic databases were searched for articles comparing TIC with FSB. Articles were assessed for methodological and reporting quality. The main summary measures were pooled sensitivity, pooled specificity, and diagnostic accuracy using bivariate generalized linear mixed models using random effects. RESULTS Fourteen studies were included. The pooled sensitivity, specificity, and diagnostic accuracy for FSB were 78%, 100%, and 98.57%. For TIC, the pooled sensitivity, specificity, and diagnostic accuracy were 74%, 98%, and 98.37%. For both methods, visual inspection of summary ROC curves and of forest plots did not show significant heterogeneity. CONCLUSION TIC showed comparable sensitivity, specificity, and accuracy to FSB and hence can be used as its substitute as a rapid and economical test for the detection of axillary lymph node metastasis during SLNB especially in low-resource settings.

Abstract
Introduction The intraoperative frozen section is a recommended method to detect breast cancer metastasis to axillary sentinel lymph nodes (SLNs); however, frozen section is not widely available and requires an experienced staff. Alternatively, touch imprint cytology (TIC) is a simple and cost-effective technique to detect metastasis. Therefore, in this study, we assessed the diagnostic accuracy of TIC for detecting SLN metastasis and compared it with intraoperative frozen section evaluation. Methodology A retrospective study was conducted in the Department of Histopathology, Liaquat National Hospital and Medical College, for a duration of two years. A total of 114 patients undergoing surgery for primary breast cancer were included in the study. All patients had clinically and radiologically negative axillary lymph nodes. SLN sampling was done using radioactive dye and sent for intraoperative consultation. The SLNs were sliced at 4-mm intervals and two TIC slides and three step-levels for frozen section were prepared, and the results were compared with final (paraffin) section histology. Results The sensitivity, specificity, and diagnostic accuracy of TIC was 83.7%, 98.5%, and 92.1%, respectively. Alternatively, the sensitivity, specificity, and diagnostic accuracy of frozen section was 93.9%, 100%, and 97.4%, respectively. The sensitivity of TIC and frozen section for detecting micrometastasis was 14.3% and 57.1%, respectively, with a diagnostic accuracy of 90.3% and 95.8%, respectively. Alternatively, with respect to macrometastasis, the sensitivity and specificity of TIC were 95.2% and 98.5%, respectively, while the sensitivity and specificity of frozen section were 100%. Conclusion TIC is a quick and effective technique for detecting breast cancer metastasis in axillary SLNs. Although frozen section had an overall higher sensitivity than TIC, the sensitivity of TIC for detecting macrometastasis was comparable to the frozen section. Therefore, we conclude that TIC is a good alternative to the frozen section in facilities where the frozen section is not available.

Abstract
Transmittance and fluorescence optical projection tomography can offer high-resolution and high-contrast visualization of whole biological specimens; however, applications are limited to samples exhibiting minimal light scattering. Our previous work demonstrated that angular-domain techniques permitted imaging of ∼1cm diameter noncleared lymph nodes because of their low scattering nature. Here, an angle-restricted transmittance/fluorescence system is presented and characterized in terms of geometric and fluorescence concentration reconstruction accuracy as well as spatial resolution, depth of focus, and fluorescence limits of detection. Using lymph node mimicking phantoms, results demonstrated promising detection and localization capabilities relevant for clinical lymph node applications.

Diagnostic criteria of sentinel lymph node micrometastasis or macrometastasis based on tissue rinse liquid-based cytology in gynecological cancer. Int J Clin Oncol 2020; 25:2138-2143. [PMID: 32851566 DOI: 10.1007/s10147-020-01774-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Accepted: 08/10/2020] [Indexed: 10/23/2022]
Abstract
OBJECTIVE This study aimed to establish intraoperative diagnostic criteria of sentinel lymph node (SLN) micro-/macrometastasis on the basis of tissue rinse liquid-based cytology (TRLBC) in gynecological cancer. METHODS We enrolled 214 patients with gynecological cancer who underwent rapid diagnosis of SLN metastasis on the basis of TRLBC from a total of 490 SLNs. For slides that were classified as positive for atypical cells on cytological inspection, we counted the number of clusters (an atypical cell mass consisted of three or more cells) and the number of single cells (an atypical cell other than clusters). Receiver operating characteristic (ROC) analysis was applied to determine the efficiency of predicting SLN micro-/macrometastasis. RESULTS On cytological inspection, 36 slides were classified as positive for atypical cells, while 21 slides (4.3%) were true positive, 15 (3.1%) were false positive, and 454 (92.6%) were true negative. There were no false negative results in this study. The area under the ROC curve for the number of cluster was superior to that for the number of single cells for distinguishing micro-/macrometastasis from negative/isolated tumor cells (0.86 vs. 0.67, P = 0.032). The optimum cut-off value of the number of clusters was 5 for distinguishing these two categories. CONCLUSIONS TRLBC is a highly sensitive alternative for detecting SLN metastasis as a rapid intraoperative diagnosis. Counting the number of atypical cell clusters might be useful for distinguishing micro-/macrometastasis from isolated tumor cells.

Abstract
PURPOSE The purpose was to assess the diagnostic accuracy of touch imprint cytology (TIC) compared with frozen section (FS) analysis as an intraoperative diagnostic tool to assess nodal metastasis in oral squamous cell carcinoma. MATERIALS AND METHODS We intraoperatively assessed 38 patients undergoing neck dissection for oral squamous cell carcinoma, wherein a total of 248 nodes were sectioned and subjected to TIC and, subsequently, FS analysis and were finally submitted to the gold-standard histopathologic examination. The sensitivities, specificities, positive predictive values (PPVs), and negative predictive values (NPVs) of TIC and FS analysis for the detection of metastasis in the cervical nodes were determined with the corresponding 95% confidence intervals. RESULTS TIC had a sensitivity of 62.86%, specificity of 96.24%, PPV of 73.33%, NPV of 94.04%, and accuracy of 91.53% compared with histopathologic results. The sensitivity of FS analysis was 60%, specificity was 98.12%, PPV was 84%, NPV was 93.72%, and accuracy was 92.74% compared with histopathologic examination. These results of TIC were comparable to those of FS analysis. CONCLUSIONS TIC is a straightforward, quick, and reliable technique. It has a definitive role in being used as an adjunct to FS analysis to increase intraoperative diagnostic accuracy. It can serve as a useful technique in centers that do not have FS availability.

Abstract
To study the technique of intra-operative imprint cytology for intraoprative diagnosis and management in cases of Head and Neck malignant lesions and to compare its result with postoperative histopathology. Prospective study conducted over 2 yrs period at the Department of ENT of a tertiary care centre in central India. A total of 60 patients who were operated for Head and Neck malignant lesions were studies with regards to intraoperative diagnosis, marginal status and lymphnodal status and compared with postoperative histopathology. Mean age-group was 47.70 (± 13.7) years. There was male preponderance. Bucco-aveolar complex lesions constituted the majority followed by Tongue and thyroid lesions. Intraoperative cytology technique showed a sensitivity of 92.98%, 80.60% and 92.30% as regards the intraoperative diagnosis, marginal clearance and nodal metastases respectively; while the specificity was 100%, 90.09% and 83.33% respectively. At the end of the study we conclude that intra-operative cytology is a good technique for intra-operative evaluation in Head and Neck lesions, where facilities for frozen section are not available. It can be used as a simple, non-expensive and rapid alternative to frozen section. A larger and longer study can validate its routine use in surgical setups where high-end pathology setup is not available.

Abstract
The widely practiced intra-operative methods for rapid evaluation and detection of sentinel lymph node (SLN) status include frozen section (FS) and touch imprint cytology (TIC). This study optimized the use of TIC and FS in the intra-operative detection of breast SLNs based on the Memorial Sloan Kettering Cancer Center (MSKCC) nomogram. Three hundred forty-two SLNs were removed from 79 patients. SLN metastatic probability was assessed by the MSKCC nomogram. The SLNs underwent intra-operative TIC and FS, as well as routine post-operative paraffin sections (RPSs). The relationships between TIC, FS, and SLN metastatic probability were analyzed. Overall, TIC was more sensitive than FS (92.31% vs. 76.92%), while TIC specificity was inferior to FS specificity (84.85% vs. 100%). In addition, the best cut-off value for TIC based on the MSKCC nomogram was inferior to the best FS cut-off value (22.5% vs. 34.5%). All patients with a MSKCC value <22.5% in the present study were negative based on FS and RPS, while the true-negative and false-positive rates for TIC were 92.5% and 7.5%, respectively. Thus, early breast cancer patients, based on a MSKCC value <22.5%, can safely avoid FS, but should have TIC performed intra-operatively. Patients with a MSKCC value >22.5% should have TIC and FS to determine the size of metastases, whether or not to proceed with axillary lymph node dissection, and to avoid easily missed metastases.

Abstract
Sentinel lymph node (SLN) biopsy has been established as the standard of care for axillary staging in patients with invasive breast carcinoma and clinically negative lymph nodes (cN0). Historically, all patients with a positive SLN underwent axillary lymph node dissection (ALND). The ACOSOG Z0011 trial showed that women with T1-T2 disease and cN0 who undergo breast-conserving surgery and whole-breast radiotherapy can safely avoid ALND. The main goal of SLN examination should be to detect all macrometastases (>2 mm). Gross sectioning of SLNs at 2-mm intervals and microscopic examination of one haematoxylin and eosin-stained section from each SLN block is the preferred method for pathological evaluation of SLNs. The role and timing of SLN biopsy for patients who have received neoadjuvant chemotherapy is controversial, and continues to be explored in clinical trials. SLN biopsies from patients with invasive breast carcinoma who have received neoadjuvant chemotherapy pose particular challenges for pathologists.

Abstract
Sentinel lymph node biopsy is an established way of predicting axillary nodal metastasis in early breast cancer. Intraoperative frozen sections (FS) of sentinel lymph nodes (SLNs) can be used to detect metastatic disease, allowing immediate axillary lymph node dissection. The purpose of this study was to evaluate the accuracy of intraoperative frozen sections in evaluation of sentinel lymph nodes in cases of breast cancer. Between March 2006 and August 2010, a total of 164 patients with clinically node-negative operable breast cancer were subjected to sentinel lymph node biopsy of axillary lymph nodes using preoperative peritumoral injection of radioactive colloid and methylene blue. Intraoperative identification of sentinel nodes was done using a handheld gamma probe and identification of blue-stained nodes. The nodes were sent for frozen section examination. The results of frozen section were compared with the final histopathology. Out of the 164 cases, metastases were detected in SLN by frozen section in 38 cases. There were three false-negative cases (all showing micrometastasis on final histopathology). FS had sensitivity of 92.6 %, specificity of 100 %, and overall accuracy of 98.1 %. The positive predictive value was 100 %, and the negative predictive value was 97.6 %. FS for diagnosis of metastasis of SLNs is reliable. Patients with negative SLNs by the FS diagnosis can avoid reoperation for axillary lymph node dissection. However, FS may fail to detect micrometastases, especially in cases with small tumors.

Abstract
Background Sentinel lymph node biopsy (SNB)-oriented stepwise treatment under local anesthesia has been performed in the outpatient-ambulatory setting in patients receiving neoadjuvant therapy (NAT). We retrospectively reviewed our preliminary experience of ambulatory SNB in breast cancer patients scheduled to undergo NAT to evaluate the usefulness and feasibility of this method as a minimally invasive, stepwise treatment protocol. Methods We retrospectively identified 56 patients with breast cancer without obvious nodal involvement who were scheduled to receive NAT before breast surgery. SNB was performed under local anesthesia in an ambulatory outpatient setting before the initiation of NAT. Results The average number of removed sentinel lymph nodes was 1.9. Identification of the sentinel node was possible in all cases, and macrometastasis was observed in six cases (10.7%). Micrometastasis was observed in five cases, while isolated tumor cells were noted in six cases. There were no delays in the initiation of NAT as a result of complications of SNB. Conclusions This pilot study demonstrated the safety and feasibility of ambulatory SNB prior to NAT. Further studies are warranted to assess the strict indications, patient satisfaction, and medical economics of this procedure.

Abstract
Objective Recently, therapies targeting the biological characteristics of individual cancers according to markers indicating underlying molecular biological mechanisms have become available. Core needle biopsy (CNB) is widely used, not only to diagnose, but also to determine therapeutic strategies, in patients with breast cancer. Although the diagnostic accuracy of CNB is acceptably high, false-negative results have occasionally been encountered. Methods The results of adjunctive imprint cytology (AIC) coinciding with CNB in 2,820 patients suspected to have breast cancer were retrospectively reviewed. The feasibility and clinical usefulness of AIC-assisted diagnosis were analyzed. Results Fourteen-hundred and sixty-four cases were diagnosed as not malignant using CNB alone. Forty-seven of 1464 cases were suspected to be malignant on a cytological review of AIC, and 42 were confirmed to be breast cancer on additional biopsies. The combination of CNB and AIC achieved a sensitivity of 100% (1398/1398) and a specificity of 99.6% (1417/1422). Small lesions and large noninvasive- or scirrhous-type carcinomas were the common features of the CNB-negative/AIC-positive cases. Conclusions Adjunctive imprint cytodiagnosis is a simple and easy procedure that assists the pathological diagnosis of breast cancer using CNB and therefore serves as a possible novel standard application.

Abstract
INTRODUCTION One-Step Nucleic acid Amplification (OSNA) is a molecular biological assay of cytokeratin-19 (a breast epithelial marker) mRNA. It can be employed intra-operatively for detection of lymph node metastases in breast carcinoma. Patients with positive sentinel nodes may proceed to axillary lymph node dissection (ALND) level I or higher dependent upon the OSNA quantitative result, during the same surgical procedure, avoiding a second operation and eliminating the technical difficulties possibly associated with delayed ALND. AIMS Our Breast Unit was the first in the UK to implement this novel technique in routine practice. This study reviews our first 44-month data following introduction of OSNA "live" on whole sentinel nodes following an extensive validation study (Snook et al.).(9) METHODS: Data was collected prospectively from the period of introduction 01/12/2008 to 30/08/2012. All patients eligible for sentinel node biopsy were offered OSNA and operations were performed by five consultant breast surgeons. On detection of macro-metastasis a level II/III and for a micro-metastasis a level I ALND was performed. RESULTS A total of 859 patients (1709 sentinel lymph nodes) were analysed. All except one were females. The majority underwent wide local excision (73.4%, n = 631) or mastectomy 25% (n = 215) and 1.6% (13) underwent SLN biopsy alone. IDC was seen in 79% (n = 680) of the patients and 53.5% (n = 460) had grade II tumours. One-third (30.8%, n = 265) had positive sentinel nodes and had further axillary surgery at the time of SLN biopsy. Of these, 47% (n = 125/265) had macro-metastases, 38% (n = 101/265) had micro-metastases and 14.7% (n = 39/265) had "positive but inhibited" results. Positive non-sentinel lymph nodes (NSLN) were seen in 35% (44/125) of those with macro-metastases; 17.8% (18/101) of the patients with micro-metastases and 10.2% (4/39) of the "positive but inhibited" group. CONCLUSION In our series over a third of our patients had positive lymph nodes detected with OSNA allowing them to proceed directly to axillary surgery at the same operation. This technique eliminates the need for a second operation in sentinel lymph node positive patients and avoids the anxiety waiting for histological results.

Abstract
OBJECTIVE Intraoperative histopatological examination of the sentinel nodes enables selection of patients who need dissection of the regional lymphatic system during the same operation. The aim of this study is to evaluate the diagnostic value of intraoperative histopathological examination of the sentinel nodes in breast cancer and skin melanoma. Intraoperative histopathology of the sentinel nodes as a diagnostic method is used in patients with melanoma and breast cancer. Recent studies have proved it to be an effective method for evaluating the nodes in the final histopathology. Intraoperative histopathological examination of the sentinel nodes is not performed routinely and there is no clear position on this issue. In this paper we try to prove that intraoperative test gives patients the simultaneous benefits of removal of regional lymph nodes metastases and earlier initiation of adjuvant therapy. METHODS The study comprises 137 patients with breast cancer and 35 patients with malignant skin melanoma. Sentinel nodes were intraoperatively sectioned and examined by means of the imprint method and frozen section evaluation. The patients with positive sentinel nodes underwent immediate dissection of regional lymph nodes. Those with negative sentinel nodes diagnosed in the intraoperative examination, but positive in final pathologic results, underwent subsequent dissection of regional lymph nodes. RESULTS 60 sentinel lymph nodes were found in 35 patients with skin melanoma. In 3 patients, 3 sentinel lymph nodes were false negative in the intraoperative histopathological examination. No false positive sentinel lymph nodes were found. 249 sentinel lymph nodes were found in the intraoperative histopathological examination in 137 patients with breast cancer. There were no false positive sentinel nodes, but there were 7 false negative sentinel nodes. In this study, only 5 (3.6%) patients with breast cancer and 3 (8.5%) patients with skin melanoma required another regional operation. CONCLUSION The method of intraoperative histopathological evaluation of the sentinel nodes enables identification of metastases in these lymph nodes and gives a possibility to carry out a one-step regional lymphadenectomy and start the adjuvant therapy earlier.

Abstract
Background Candidemia is a severe fungal infection that primarily affects hospitalized and/or immunocompromised patients. Mononuclear phagocytes have been recognized as pivotal immune cells which act in the recognition of pathogens, phagocytosis, inflammation, polarization of adaptive immune response and tissue repair. Experimental studies have showed that the systemic candidiasis could be controlled by activated peritoneal macrophages. However, the mechanism to explain how these cells act in distant tissue during a systemic fungal infection is still to be elucidated. In the present study we investigate the in vivo trafficking of phagocytic peritoneal cells into infected organs in hypoinsulinemic-hyperglycemic (HH) mice with systemic candidiasis. Methods The red fluorescent vital dye PKH-26 PCL was injected into the peritoneal cavity of Swiss mice 24 hours before the intravenous inoculation with Candida albicans. After 24 and 48 hours and 7 days of infection, samples of the spleen, liver, kidneys, brain and lungs were submitted to the microbiological evaluation as well as to phagocytic peritoneal cell trafficking analyses by fluorescence microscopy. Results In the present study, PKH+ cells were observed in the peritoneum, kidney, spleen and liver samples from all groups. In infected mice, we also found PKH+ cells in the lung and brain. The HH condition did not affect this process. Conclusions In the present study we have observed that peritoneal phagocytes migrate to tissues infected by C. albicans and the HH condition did not interfere in this process.

Abstract
OBJECTIVES Sentinel lymph node (SLN) examination in breast carcinoma is crucial to spare patients unnecessary lymph node (LN) dissection. The specificity and accuracy of SLN examination by frozen section has been variable in many studies. This study aims to describe our experience in frozen section (FS) analysis of SLN. METHODS We have retrospectively analyzed data from 449 axillary SLN subjected to FS examination from 440 patients with breast cancer. All patients had free axillary LN clinically. RESULTS Out of 449 cases, no false positive cases were found on FS (specificity of 100 %). Twenty-six cases were false negative (6 interpretation-related reasons and 20 technical-related reasons). The overall sensitivity was 84 % with a total accuracy rate of 93 % and interpretation sensitivity of 96 %. Three cases were deferred. Twenty-two of the false negative cases were micrometastases, whereas 4 were macrometastases. The interpretation-related false negative cases were not related to the subtype of carcinoma (ductal vs. lobular). However, they were all of low nuclear grade. CONCLUSION These findings are similar to most published data. FS is a reliable method for evaluating SLN. The most common cause of false negative diagnosis is sampling error. More attention should be paid to low-grade tumors. Moreover, in FS analysis, we recommend to totally submit SLNs that are less than 5 mm in diameter, bisecting them if possible, and to serially section SLNs that are at least 5 mm at 2-mm intervals.

Abstract
BACKGROUND Most centers use lymphoscintiscan for identification of a sentinel lymph node (SLN) and frozen section for its evaluation. The aim of the present study was to assess the accuracy of peritumoral methylene blue dye injection for SLN identification and the technique of touch imprint cytology (TIC) for its evaluation. PATIENTS AND METHODS One hundred and eight fine needle aspiration cytology (FNAC)-proven breast cancer patients with clinically N0 axilla were recruited for the study. Prior to the induction of anesthesia, 5 ml of 1% methylene blue was injected in the peritumoral region to stain the sentinel node, following which conventional modified radical mastectomy was performed. Touch imprint cytology was obtained from the cut surface of the SLN, and then the SLN along with all nonsentinel nodes were sent for histopathology. RESULTS Intraoperative identification of a blue node was possible in 102 of 108 patients (94%). Touch imprint cytology had a sensitivity of 88%, specificity of 98%, and overall diagnostic accuracy of 94% for diagnosing metastasis in the SLN. The false positive rate for malignancy of TIC versus histology was 2.5% and the false negative rate 7.8%. CONCLUSIONS Blue dye lymphatic mapping by peritumoral injection of methylene blue was found to be accurate and cost effective for SLN identification. It avoids the expenses of lymphoscintiscanning, which requires special infrastructure and expertise with a significant learning curve. The identified SLN can, with reasonable accuracy, be assessed for metastasis by TIC. The frequently used method of frozen section requires a cryostat and a pathologist trained in the technique. Additionally scanty SLN tissue can be wasted in the cryostat and freezing artifacts can be introduced in the imprint, both of which are avoided by TIC.

Abstract
BACKGROUND The evaluation of sentinel lymph nodes (SLNs) from a patient with lobular breast cancer is challenging. Metastatic lobular cancer is difficult to identify in SLNs because of its low-grade cytomorphology and its tendency to resemble lymphocytes. Intraoperative imprint cytology (IIC) is a rapid, reliable method for evaluating SLNs intraoperatively. We sought to reexamine our experience with this technique in the identification of invasive lobular breast cancer SLN metastases. METHODS A retrospective review of a prospectively maintained database of IIC results of 1010 SLN mapping procedures for breast cancer was performed. From this cohort we reviewed SLN cases of lobular cancer. The SLNs were evaluated intraoperatively by bisecting the SLN. Imprints were made of each cut surface and stained with hematoxylin and eosin (H&E) and Diff-Quik. Permanent sections were evaluated with up to 4 H&E-stained levels and cytokeratin immunohistochemistry. IIC results were compared with final pathologic results. RESULTS A total of 67 cases of pure invasive lobular cancer were identified. The sensitivity was 71%, specificity was 100%, and accuracy was 92%. No statistically significant differences in sensitivity, specificity, or accuracy were identified between the intraoperative detection of lobular carcinoma vs ductal carcinoma. The specificity has remained the same since 2004. However the accuracy (82% vs 92%; P = .09) and sensitivity (52% vs 71%; P = .02) has improved since 2004. CONCLUSIONS As we have previously shown, the sensitivity and specificity of IIC in evaluating lobular carcinoma is feasible and accurate. IIC continues to be a viable alternative to frozen section for intraoperative evaluation.

Abstract
OBJECTIVES A prospective study was carried out to evaluate the role of intra-operative touch imprint cytology (TIC) in the assessment of sentinel lymph node (SLN) involvement for staging and treatment of early-stage, clinically node-negative breast carcinoma. METHODS Forty-five patients with early-stage, clinically node-negative breast cancer underwent a SLN biopsy with intra-operative TIC. The SLN was bisected if its width was less than 4 mm or sliced every 2 mm if it was more than 4 mm. The imprint specimens were stained with haematoxylin and eosin (H&E). Rapid immunochemistry (IH) was performed in case of equivocal cytological result. Permanent sections were evaluated with H&E and IH staining. The results of TIC were compared to histopathological results. RESULTS The sensitivity, specificity and overall accuracy of TIC on a node basis were 65.5%, 96.3%, 85.5%, respectively. When calculated according to the size of SLN metastasis, the sensitivity of TIC for overt metastasis was 84.6%, while it was 62.5% for micrometastasis and 37.5% for sub-micrometastasis. The mean size of nodal metastasis was 5.08 mm and 1.25 mm for true positive and false negative results, respectively (P = 0.0236). Because of intra-operative TIC, 76.5% of the patients who needed further axillary lymph node dissection (ALND) could undergo this during the same operating time. CONCLUSIONS TIC is a rapid and reliable method for the intra-operative assessment of metastatic sentinel node involvement in patients with early-stage, clinically node-negative breast carcinoma. Despite a low sensitivity comparable to frozen section (FS) in detecting micro- and sub-micrometastases, the technique offers the advantage of full tissue preservation for subsequent histological analysis.

Abstract
Accurate intraoperative diagnosis of sentinel node metastasis enables the surgeon to make an immediate decision to proceed to axillary lymph node dissection (ALND), thereby avoiding the economic and psychological costs of a second operation. The present study aimed to evaluate the clinical value of touch imprint cytology (TIC) and investigate the potential factors associated with misdiagnosis. A total of 366 patients with Tis-T2 breast carcinoma were included after undergoing successful sentinel lymph node biopsy (SLNB). TIC was routinely performed intraoperatively, and the results were compared with definitive histological assessments of serial sections (SS) with hematoxylin and eosin (H&E) staining. A total of 992 SLNs from 366 patients were used in the study. Based on the final histological diagnosis, the sensitivity, specificity and overall accuracy of TIC was 76.6, 98.8 and 92.3%, respectively, on a per patient basis, and 79.9, 98.9 and 96.1%, respectively, on a per node basis. TIC was significantly more sensitive for macrometastasis than micrometastasis (80.0 vs. 28.6%, P<0.01). Of 9 total 'false positives', 3 were due to micrometastasis which were not identified by serial section with H&E staining, 4 were actual false-positives which were due to interpretation error, and 2 were due to sampling error. The majority of the false-negatives (28 of 30 SLNs) were due to micrometastasis in the SLNs (sampling error). In conclusion, TIC is feasible for clinical use and is able to detect macrometastasis in the SLNs of early stage invasive breast cancer patients with an acceptable accuracy while its ability to detect micrometastasis is limited.

Abstract
BACKGROUND The potential for reducing the need for second surgery for axillary lymph node dissection (ALND) has made the intraoperative evaluation of sentinel lymph nodes (SLNs) attractive. The goal of the current study was to evaluate the clinical application of the breast lymph node (BLN) assay, a real-time reverse transcriptase-polymerase chain reaction assay for SLN metastases, by comparing this test with routine pathologic examination. METHODS A total of 117 patients with breast cancer underwent breast surgery with SLN biopsy. Each SLN was cut in half along the plane of the longest dimension. Half of each lymph node was examined by the 2 markers of the BLN assay, mammaglobin and cytokeratin 19, and the other half was examined by hematoxylin and eosin staining (H&E) and immunohistochemical staining (IHC) for pancytokeratins. RESULTS A total of 204 SLNs were obtained from 117 patients. H&E staining identified metastases in 31 SLNs (15.2%), and IHC staining detected metastases in 6 SLNs; 40 SLNs from 32 patients were found to be positive for metastasis using the BLN assay. The assay results were correlated with the pathologic diagnoses by H&E and IHC staining (P<.001). The sensitivity of the BLN assay compared with pathologic findings classified according to the TNM classification was 95.7% for macrometastases, 60.0% for micrometastases, and 55.6% for isolated tumor cells. CONCLUSIONS The 2-marker BLN assay performs in a manner that is comparable to, and analyzes more tissue than, routine pathologic examination. Therefore, clinical intraoperative use of the BLN assay for SLNs may result in a reduction in the need for second surgery for ALND.

Abstract
CONTEXT The sensitivity of an intraoperative diagnosis of sentinel lymph node metastasis of invasive lobular carcinoma using conventional staining is low. OBJECTIVE To develop a fast, modified, Alcian blue stain to decrease the intraoperative false-negative results in testing for metastatic invasive lobular carcinoma. DESIGN Modified Alcian blue was optimized. Patients who had invasive lobular carcinoma on needle biopsy were candidates for this study. Touch preparations from every sentinel lymph node were prospectively prepared in the same manner, one stained with modified Alcian blue and one with conventional staining. These slides were independently interpreted. RESULTS A total of 121 sentinel lymph nodes from 31 patients with invasive lobular carcinoma were studied. There were 11 patients (35.5%) who had at least one positive lymph node test result. There were a total of 18 positive lymph node results (14.9%). Although 10 sentinel lymph nodes with abnormalities were detected in 7 patients with conventional staining, modified Alcian blue detected 15 sentinel lymph node abnormalities in 10 patients. Modified Alcian blue increased the sensitivity compared with conventional staining from 63.6% to 90.9% (calculated based on the number of patients) and from 55.6% to 83.3% (calculated based on number of sentinel lymph nodes). The staining process takes approximately 11 minutes. CONCLUSIONS Modified Alcian blue stain is a relatively rapid, cheap, highly sensitive, and specific method of detecting metastatic invasive lobular carcinoma. This method can be used in conjunction with conventional staining methods used intraoperatively.

Abstract
BackgroundIntraoperative frozen section (FS) examination in thoracic surgery is a reliable method for diagnosis and staging of pulmonary lesions and provides a valuable guide in directing the extent of the ongoing surgical procedure. However, the contribution of touch preparation cytology (TPC) to FS diagnosis remains unclear.AimTo assess the utility of routinely performed TPC during FS diagnoses of pulmonary lesions.MethodsIn this study FS and TPC for all patients who had undergone FS diagnoses of pulmonary lesions in a 6-year period were reviewed by two pathologists.ResultsA total of 155 consecutive patients underwent intraoperative FS procedure, and 110 of those cases had TPC available for review. TPC was diagnostic or contributory to FS diagnosis in 97 (88%) cases, and non-contributory in 13 cases, mainly due to low or inadequate cellularity. TPC provided useful information regarding tumour subtyping, but it was less sensitive in the diagnosis of mucinous neoplasms and was less specific in the assessment of bronchial resection margins. In granulomatous lesions with or without necrosis, TPC was diagnostic in 10 (91%) cases. In five cases (including four cases of tuberculosis), TPC was the only diagnostic tool since FS was not completed. In conclusion, TPC showed high sensitivity and specificity rates and was contributory to FS diagnosis of pulmonary lesions. TPC provides a fast, less-expensive method of diagnosis, utilises a minimal amount of tissue, and can save processing of fresh frozen tissues in certain situations such as tuberculous lesions.

Abstract
BACKGROUND Sentinel lymph node (SLN) biopsy has replaced axillary sampling as the axillary staging procedure of choice in patients with breast cancer. Accurate intraoperative evaluation of the SLN would allow axillary lymph node clearance to be performed during the initial operation when the SLN is positive for metastatic disease. The aim of the present study was to assess the accuracy of intraoperative imprint cytology (IC) of the SLN in two different institutions in the United Kingdom. METHODS All breast cancer patients who underwent a SLN biopsy using a standard protocol in two hospital breast units were included. The SLN was sent fresh to the pathology laboratory, where it was immediately processed and examined by a cytopathologist using IC. The intraoperative IC results were compared with the final histopathological results. No therapeutic decisions were made based on the results of IC in this study. RESULTS A total of 166 patients were included, with 47 positive and 119 negative cases on final histology. Of the 47 patients who were positive on final histology, there were 29 positive and 18 negative cases on IC (sensitivity = 61.7%). All 119 patients who were negative on final histology were negative on IC (specificity, 100%). The negative and positive predictive value of the final histology was 86.9% and 100%, respectively. The accuracy of IC was 89.2%. CONCLUSIONS The results from these two breast units are comparable with findings reported in the published literature, confirming that IC can be used to assess SLN biopsy intraoperatively. No unnecessary axillary node clearance would have been carried out based on the results of IC.

Abstract
BACKGROUND Intraoperative imprint cytology (IC) is one of several accurate, proven methods to detect tumor cells in sentinel lymph nodes (SLN) from patients with operable breast cancer. In patients treated with neoadjuvant chemotherapy (NAC), studies have demonstrated the feasibility and accuracy of SLN biopsy procedure. We evaluated the validity of IC for SLN testing in patients after NAC. MATERIAL AND METHODS Patients with infiltrating breast carcinoma receiving NAC (n = 132) were studied prospectively. At surgery, SLN biopsy followed by axillary lymph node dissection was performed. SLN were evaluated using IC in 80 of 132 patients (60%). The results of IC in the adjuvant setting (100 patients) were used for comparison. RESULTS SLN metastases were correctly identified using IC in 58 of 80 (72%) patients. False negative results were observed in 21 patients. The sensitivity of IC testing was 38.2% and specificity 97.8%. The positive and negative predictive values (PPV and NPV) were 92.9% and 68.2%, respectively. In univariate analysis and multivariate logistic regression analysis, patients with micrometastases or isolated tumor cells in SLN have 2.3 times higher risk of a false negative IC result than patients with macrometastases in SLN (P = .00021; relative risk [RR] = 2.3; 95% confidence interval, 1.37-3.85). The non-NAC group, which contained fewer micrometastatic cases, showed better sensitivity (47.4%) and NPV (88.9%). CONCLUSION NAC does not seem to influence the accuracy and sensitivity of IC. Variations in sensitivity are related to the proportion of cases with micrometastases and ITC, as it was also shown in chemonaive patients.

Abstract
INTRODUCTION Sentinel lymph node biopsy (SLNB) is the standard of care to assess the metastasis in breast carcinoma. Accuracy of intraoperative frozen section examination to evaluate SLN in detecting metastasis is important as it determines the further management of axilla. Primary tumor characteristics determining the metastasis to the lymph node will help in predicting the probability of spread and to determine the nature of disease. It also helps in refining selection of patients for SLNB. We evaluated all these criteria on Indian patients for the better management. MATERIALS AND METHODS Between January 2005 and April 2009, 114 consecutive patients of all age group of both sex, with cytology or biopsy proven carcinoma breast, clinical stage T1/T2 N0 M0 at Manipal Comprehensive Cancer Center, Manipal Hospital, Bangalore were subjected to SLNB and introperative frozen examination. First 75 cases had complete axillary clearance irrespective of SLNB result and subsequently, positive cases underwent axillary lymph node dissection (ALND). Age of the patient and primary tumor characteristics like size, grade, lymphovascular invasion (LVI), perineural invasion, ER/PR status, Her2-neu status and histological sub-types were evaluated for predicting the SLN metastasis. Feasibility of SLNB in previously treated patient is also evaluated. RESULTS The age of the patient ranged from 23 to 87 years and its association with SLN spread is not significant. Frozen section examination had accuracy of 97.37% in determining metastatic sentinel node with sensitivity of 96.15% and specificity of 100% with value P < 0.001. SLN remained significant indicator of the status of rest of axilla with value P < 0.001. Primary tumor characteristics like histological subtypes, grade (P = 0.353), ER/PR status (P = 0.839), Her2-neu status (P =0.296) were not significantly associated with SLN metastasis. Size of the primary tumor (P = 0.002), LVI (P < 0.001), perineural invasion (P = 0.084+) were significant factors determining the SLN metastasis. SLNB evaluation had no false negative values in previously treated breast. CONCLUSION SLNB is a valuable method of determining the axillary nodal metastasis. Intraoperative frozen section examination is highly ac-curate in detecting nodal metastasis. Primary tumor characteristics like size, LVI and perineural invasion are significant in predicting SLN metastasis. SLNB remains an important method of predicting axillary metastasis even in previously treated breast carcinomas.

Abstract
BACKGROUND Sentinel lymph node (SLN) biopsy has been shown to be both accurate and feasible for women who receive neoadjuvant chemotherapy (NAC). This study was designed to evaluate the ability of intraoperative assessment to predict metastasis in the sentinel node after NAC and to compare it with patients not treated with NAC. METHODS Thirty-seven patients with invasive breast cancer and SLN biopsy after NAC and 461 patients with invasive breast cancer not treated with NAC were included in the study. The SLN was identified by the gamma probe and sent to pathology for frozen (FS) and H&E paraffin-sections. If the SLN was negative by H&E paraffin-sections, then immunohistochemistry was performed. RESULTS The sensitivity of FS in the NAC group ranged from 78.5% for micro and isolated tumor cells to 100% for macrometastasis. The sensitivity of FS in the non-NAC group ranged from 82% for micro and isolated tumor cells to 97.4% for macrometastasis. There were no statistically differences between the sensitivities of FS in the two groups. Nine (64.2%) of the 14 patients in the NAC group with metastasis to the SLN had other non-SLN metastasis. CONCLUSIONS After NAC, FS is an effective method for detecting macrometastasis in the SLN. As in the adjuvant setting, the sensitivity of FS is lower for SLN micro and sub-micrometastasis. Intraoperative FS of the SLN after NAC is indicated to avoid a second surgery because 60% of patients with a positive SLN will have additional positive axillary nodes.

Abstract
This study was conducted to confirm which of these modalities [mammography (MG), fine-needle aspiration cytology (FNAC), core-needle biopsy (CNB), or intraoperative touch imprint cytology (IOTIC)] is useful to detect breast cancer and to compare the accuracy of these modalities for the diagnostic setting. One hundred seventy-five, 85, 78, and 25 patients were selected who underwent FNAC, MG, IOTIC, and CNB, respectively. Histopathology was used as a gold standard for comparison of the results of all diagnostic modalities. Twenty-five patients with combinations of three preoperative tests (MG, FNAC, CNB) showed 100% accurate results when compared with histopathology, while the overall accuracy for MG, FNAC, and CNB was 91.7%, 91.5%, and 96%, respectively. Both touch and scrape imprints' sensitivity, specificity, positive predictive value, negative predictive value (NPV), and accuracy were 100% for class V and class II smears, while sensitivity, accuracy, and NPV were 87, 95, and 83% for IOTIC and 94%, 96%, and 89% for IOSC for class III and IV smears. On comparison of the results of all these procedures, the difference was nonspecific (P = 0.2, 0.3, 0.5, 0.55, and 0.6 for MG, FNAC, IOTI, IOSC, and CNB, respectively). Combinations of preoperative tests (MG, FNAC, CNB) were more accurate, reliable, and acceptable when compared with individual diagnostic procedure, but these have their own technical limitations. The accuracy of CNB was much higher than that of MG and FNAC. IOTP and IOSC are simple and cost effective diagnostic tests with better accuracy that can be used as an alternate to frozen section in diagnostic settings and margin assessments.

Abstract
BACKGROUND The intraoperative evaluation of axillary sentinel lymph nodes (SLNs) allows the surgeon to complete axillary dissection in 1 setting at the time of the primary breast surgery. However, to the authors' knowledge, there is no consensus regarding the optimal method for intraoperative evaluation of SLNs in breast cancer. The authors of this report prospectively compared touch imprint (TI) cytology with frozen section (FS) analysis and rapid cytokeratin immunostaining (RCI) of SLNs for the intraoperative evaluation of disease and compared the results with final pathologic examination (FP). METHODS Patients with invasive breast carcinoma who were diagnosed with lymph node-negative disease (based on preoperative clinical and sonographic evaluation with or without fine-needle aspiration of the indeterminate lymph nodes) and who subsequently were scheduled for lymphatic mapping were eligible to participate in this prospective protocol. TI and FS analysis were performed on all SLNs, and the lymph nodes were stained by the hematoxylin and eosin (H&E) method. RCI was performed using the enhanced polymer 1-step cytokeratin method. The results of TI, FS, RCI, TI plus FS, and FS plus RCI were compared with the results from FP, including 1 H&E stain and cytokeratin immunostain of the third level. RESULTS One hundred patients with invasive mammary carcinoma were accrued to the study. Eighty-five tumors were the ductal type, 8 tumors were lobular, 5 tumors were mixed ductal and lobular, 1 was an adenoid cystic tumor, and 1 tumor was metaplastic carcinoma. Seventy-two tumors were staged clinically as T1N0M0, 25 tumors were staged as T2N0M0, and 3 tumors were staged as T3N0M0. Metastatic carcinoma was detected in the SLNs by 1 or more methods, including TI, FS, RCI, and FP, in 20 tumors, which included 12 macrometastases and 8 micrometastases. TI detected 8 of 12 macrometastases (67%), FS detected 12 of 12 macrometastases (100%), RCI detected 12 of 12 macrometastases (100%), and FP detected 12 of 12 macrometastases (100%). TI detected 1 of 8 micrometastases (13%), FS detected 3 of 8 micrometastases (38%), RCI detected 4 of 8 micrometastases (50%), and FP detected 6 of 8 micrometastases (75%). The sensitivities of TI, FS, RCI, TI plus FS, and FS plus RCI (with FP as the gold standard) were 50%, 72%, 78%, and 83%, respectively, and the sensitivities of the same intraoperative methods were 45%, 75%, 80%, and 85%, respectively, with detection of metastatic disease by any method as the gold standard. The specificities of the different methods (with FP as the gold standard) were 100% for TI and 97.5% for FS, RCI, TI plus FS, and FS plus RCI. The specificity of each method was 100% when the detection of metastatic disease by any method was regarded as the gold standard. Although the difference in sensitivity between FS and TI was not statistically significant (P = .08), the difference between RCI and TI bordered on significance (P = .046); however, FS analysis plus RCI was significantly superior to TI (P = .03) and produced results comparable to those of FP. CONCLUSIONS The sensitivities of FS, RCI, TI plus FS, and FS plus RCI were better than the sensitivity of TI cytology of axillary SLNs. However, only the combination of FS and RCI was statistically superior to TI and generated results comparable to those of FP in SLNs. RCI can be completed within the time constraints for intraoperative use and, in conjunction with FS, can be useful for generating results closer to those generated by FP. FS analysis plus RCI have a role in the intraoperative evaluation of SLNs.
