Abstract
Background: Lymphedema may develop when axillary lymph node dissection (ALND) injures and obstructs the lymph ducts in the upper limb. In patients with breast cancer, lymphedema is difficult to treat and can cause arm swelling, heaviness, and restricted movement. We aimed to identify the prevalence and risk factors for lymphedema after ALND in patients with breast cancer. Methods and Results: This retrospective study included 175 patients with breast cancer who underwent ALND in the Nagasaki University Hospital, Japan, between 2005 and 2018. Lymphedema was defined as symptomatic arm swelling with a >2-cm difference in the arm circumference between the affected and contralateral arms. Patients were divided into two groups according to the presence or absence of lymphedema. Surgical and pathological findings were compared between the two groups. Univariate and multivariate analyses were performed, including the chi-square test, Student's t-test, and logistic regression analysis. Lymphedema was prevalent in 20% of the study participants, and the mean time interval from surgery to development of lymphedema was 479 days. In the univariate analysis, a body mass index of >26 kg/m2, smoking, radiotherapy (RT), and dissection of >18 axillary lymph nodes (ALNs) significantly increased the risk of lymphedema. In the multivariate analysis, smoking, RT, and dissection of >18 ALNs significantly increased the risk of lymphedema. Conclusions: The prevalence of lymphedema in our study was 20%. Our findings suggest that smoking, RT, and dissection of >18 ALNs are risk factors for lymphedema. Aggressive and empiric ALND might be associated with axillary lymph duct damage.

Abstract
PURPOSE Although the impact of lymph node ratio (LNR: ratio of metastatic to resected LNs) in breast cancer (BC) has been investigated, its prognostic value in molecular subtypes remains unclear. Our aim was to evaluate the impact of LNR compared to pN-stage in BC subtypes. PATIENTS/METHODS We analyzed the impact of LNR and pN-stage on disease-free (DFS) and overall survival (OS) in 1,656 patients with primary BC who underwent primary axillary surgery (removal of ≥10 LNs) between 1998 and 2011. The cut-off points for LNR were previously published. Using immunohistochemical parameters tumors were grouped in luminalA, luminalB/HER2-, luminalB/HER2+, HER2+ and triple negative (TNBC). RESULTS For the entire cohort 5/10-year DFS and OS rates were 88/77% and 88/75%, respectively. LNR and pN-stage were independent prognostic parameters for DFS/OS in multivariate analysis in the entire cohort and each molecular subgroup (p < 0.001). However, increasing LNR seemed to discriminated 10-year DFS slightly better than pN-stage in luminalA (intermediate/high LNR 65/44% versus pN2/pN3 71/53%), luminalB/HER2- (intermediate/high LNR 48/24% versus pN2/pN3 41/42%), and TNBC patients (intermediate/high LNR 49/24% versus pN2/pN3 56/33%). CONCLUSIONS LNR is an important prognostic parameter for DFS/OS and might provide potentially more information than pN-stage in different molecular subtypes.

Neoadjuvant chemotherapy in breast cancer significantly reduces number of yielded lymph nodes by axillary dissection. BMC Cancer 2014; 14:4.

Abstract
Background Neoadjuvant chemotherapy (NC) is an established therapy in breast cancer, able to downstage positive axillary lymph nodes, but might hamper their detectibility. Even if clinical observations suggest lower lymph node yield (LNY) after NC, data are inconclusive and it is unclear whether NC dependent parameters influence detection rates by axillary lymph node dissection (ALND). Methods We analyzed retrospectively the LNY in 182 patients with ALND after NC and 351 patients with primary ALND. Impact of surgery or pathological examination and specific histomorphological alterations were evaluated. Outcome analyses regarding recurrence rates, disease free (DFS) and overall survival (OS) were performed. Results Axillary LNY was significantly lower in the NC in comparison to the primary surgery group (median 13 vs. 16; p < 0.0001). The likelihood of incomplete axillary staging was four times higher in the NC group (14.8% vs. 3.4%, p < 0.0001). Multivariate analyses excluded any influence by surgeon or pathologist. However, the chemotherapy dependent histological feature lymphoid depletion was an independent predictive factor for a lower LNY. Outcome analyses revealed no significant impact of the LNY on local and regional recurrence rates as well as DFS and OS, respectively. Conclusion NC significantly reduces the LNY by ALND and has profound effects on the histomorphological appearance of lymph nodes. The current recommendations for a minimum removal of 10 lymph nodes by ALND are clearly compromised by the clinically already established concept of NC. The LNY of less than 10 by ALND after NC might not be indicative for an insufficient axillary staging.

Abstract
PURPOSE To establish whether a different number of lymph nodes is identified in a delayed versus an immediate axillary lymph node dissection (ALND) in breast cancer patients. METHODS Using data from the Danish National Patient Register and the Danish Breast Cancer Cooperative Group Database we identified 864 breast cancer patients with sentinel lymph node dissection (SLND) and delayed ALND and 7393 breast cancer patients with SLND and immediate ALND operated between 2002 and 2010. We compared the number of lymph nodes identified in the two groups by a student's t-test. RESULTS The mean number of lymph nodes identified in patients with immediate and delayed ALND was 16.55 and 15.59, respectively. This difference was statistically significant (P < 0.0001). CONCLUSION The number of lymph nodes identified in breast cancer patients is slightly reduced if delayed ALND is performed. However, the difference is small and considered to be without clinical significance.

Abstract
BACKGROUND Because of its rarity, adenocarcinoma of the small intestine is frequently compared to adenocarcinoma of the colon, although the validity of this comparison is not known. METHODS Patients with small and large bowel adenocarcinoma (SBA and LBA) diagnosed between 1988 and 2007 were identified from the Surveillance, Epidemiology, and End Results registry. Age-standardized incidence and mortality rates were determined. Cancer-specific survival (CSS) stratified by stage and by number of assessed lymph nodes was calculated. RESULTS A total of 4518 and 261,521 patients with SBA and LBA, respectively, were identified. In comparison to LBA, patients with SBA were younger and presented with disease of higher stage and histologic grade. The age-standardized incidence rates decreased for LBA (-1.24% per year) but increased for SBA (+1.47% per year). Although age-standardized mortality rates decreased for both LBA and SBA, the decreases were more pronounced for LBA. Five-year CSS was worse for resected SBA compared with resected LBA, although this difference diminished when comparing cases having eight or more lymph nodes assessed. The relative reduction in CSS when selecting eight or more lymph nodes was much greater for duodenal as opposed to jejunal/ileal subsite of the small bowel. With nodal selection the absolute difference in CSS between LBA and SBA for stages I, II, and III was 13, 15.9, and 18.5%, respectively. CONCLUSIONS Adequate nodal assessment is much less common in SBA than LBA; and it appears that SBA, in particular duodenal adenocarcinoma, is understaged. Even after corrections to minimize the effect of stage migration and inadequate lymph node evaluation, SBA demonstrated distinctly worse CSS than LBA.

Abstract
We evaluated the prognostic significance of lymph node ratio (LNR), number of metastatic lymph nodes divided by number of removed nodes in 924 breast carcinoma patients with 1-3 metastatic axillary lymph node(s). The most significant LNR threshold value separating patients in low- and high-risk groups with significant survival difference was 0.20 for disease-free survival (P < 0.001), 0.30 for locoregional recurrence-free survival (P < 0.001), and 0.15 for distant metastasis-free survival (P < 0.001), and the patients with lower LNR had better survival. All three LNR threshold values had independent prognostic significance in Cox analysis (P < 0.001 for all three of them). In conclusion, LNR is a useful tool in separating breast carcinoma patients with 1-3 metastatic lymph node(s) into low- and high-risk prognostic groups.

Abstract
PURPOSE Little evidence can be found about the long-term outcome of breast cancer patients after axillary lymph node recurrence (ALNR) and its survival benefit after different kinds of management. The present study intends to evaluate the risk factors associated with axillary recurrence after definite surgery for primary breast cancer. The prognosis after ALNR and particularly outcome of different management methods also were studied. METHODS We retrospectively reviewed data from 4,473 patients who were diagnosed with primary breast cancer and received surgical intervention in a single institute from January 1990 to December 2002. Medical files were reviewed and data on survival were updated annually. Risk factors and prognosis of patients with axillary recurrence were analyzed. Breast-cancer-specific survival of patients with ALNR and outcomes after different management methods also were studied. RESULTS After a median follow-up of 70.2 months, axillary recurrence developed in 0.8% of patients. Factors associated with ALNR included: age younger than 40 years, medial tumor location, no initial standard level I & II axillary dissection, and not receiving hormonal therapy. The 5-year breast-cancer-specific survival after ALNR was 57.9%. For patients who received further axillary dissection, the 5-year survival rate was 82.5% compared with 44.9% for patients who did not receive further dissection. CONCLUSIONS ALNR is a rare event in treating breast cancer. Young age at diagnosis and medially located tumor are associated with higher risk, but standardized initial axillary dissection to level II and adjuvant hormonal therapy is protective against ALNR. In patients with ALNR, the outcome is not dismal and survival may be improved if further axillary dissection is given.

Abstract
OBJECTIVES We assessed the influence of tumor size and surgical approach on the use of lymphadenectomy and adrenalectomy with radical nephrectomy. METHODS We evaluated patients with renal cell carcinoma (RCC) enrolled in the U.S. Kidney Cancer Study, a case-control study in the metropolitan areas of Detroit and Chicago from 2002 to 2007. We identified patients who underwent open (ORN) or laparoscopic radical nephrectomy (LRN). We used medical records and Surveillance, Epidemiology, and End Results (SEER) data to determine the proportion of patients who underwent lymphadenectomy or adrenalectomy. Bivariate analyses were performed to evaluate associations between tumor size, surgical approach, and receipt of lymphadenectomy or adrenalectomy. RESULTS We identified 730 patients who underwent ORN (427, 58%) or LRN (303, 42%) for RCC from 2002 to 2007. Among this group, 11% and 24% underwent lymphadenectomy or adrenalectomy, respectively. Lymphadenectomy was more common among patients treated from an open surgical approach (14.1% ORN vs. 5.9% LRN, P < 0.01); this difference was most pronounced for cases with tumors between 4 and 7 cm (15.9% vs. 2.9%, P = 0.01). Patients treated with ORN were also more likely to undergo adrenalectomy, with the greatest discrepancy among cases with tumors ≤ 4 cm (21.7% vs. 11.4%, P < 0.01). CONCLUSIONS Among patients undergoing radical nephrectomy for RCC, the use of lymphadenectomy and adrenalectomy is relatively uncommon and varies by tumor size and surgical approach. With an increasing number of patients with small tumors, the diffusion of laparoscopy, and the emergence of clinical trials evaluating systemic adjuvant therapies, our findings highlight important considerations for optimizing surgical management of patients with RCC.

Abstract
Purpose We assessed changes in advanced cancer incidence and cancer mortality in eight randomized trials of breast cancer screening. Patients and Methods Depending on published data, advanced cancer was defined as cancer ≥ 20 mm in size (four trials), stage II+ (four trials), and ≥ one positive lymph node (one trial). For each trial, we obtained the estimated relative risk (RR) and 95% CI between the intervention and control groups, for both breast cancer mortality and diagnosis of advanced breast cancer. Using a meta-regression approach, log(RR-mortality) was regressed on log(RR-advanced cancer), weighting each trial by the reciprocal of the square of the standard error of log(RR) for mortality. Results RR for advanced breast cancer ranged from 0.69 (95% CI, 0.61 to 0.78) in the Swedish Two-County Trial to 0.97 (95% CI, 0.97 to 1.25) in the Canadian National Breast Screening Study-1 (NBSS-1) trial. Log(RR)s for advanced cancer were highly predictive of log(RR)s for mortality (R2 = 0.95; P < .0001), and the linear regression curve had a slope of 1.00 (95% CI, 0.76 to 1.25) after fixing the intercept to zero. The slope changed only slightly after excluding the Two-County Trial and the Canadian NBSS-1 and NBSS-2 trials. Conclusion In trials on breast cancer screening, for each unit decrease in incidence of advanced breast cancer, there was an equal decrease in breast cancer mortality. Monitoring of incidence of advanced breast cancer may provide information on the current impact of screening on breast cancer mortality in the general population.

Abstract
The number of positive axillary nodes is a strong prognostic factor in breast cancer, but is affected by variability in nodal staging technique yielding varying numbers of excised nodes. The nodal ratio of positive to excised nodes is an alternative that could address this variability. Our 2006 review found that the nodal ratio consistently outperformed the number of positive nodes, providing strong arguments for the use of nodal ratios in breast cancer staging and management. New evidence has continued to accrue confirming the prognostic significance of nodal ratios in various worldwide population settings. This review provides an updated summary of available data, and discusses the potential application of the nodal ratio to breast cancer staging and prognostication, its role in the context of modern surgical techniques such as sentinel node biopsy, and its potential correlations with new biologic markers such as circulating tumor cells and breast cancer stem cells.

PURPOSE The optimal number of axillary nodes to be resected is controversial. This large series investigated the effect of surgery with or without adjuvant radiotherapy among node-negative breast cancer patients in relation to the number of nodes examined. METHODS AND MATERIALS Node-negative patients from the Saskatchewan registry of 1981-1995 were studied. Because nodal status may be more reliable with more number of nodes examined, we analyzed T1-2 age < 90 patients with < 10 nodes examined treated with surgery alone (Group A_S, n = 509) vs. surgery and adjuvant radiotherapy (Group A_S+R, n = 342); and T1-2 age < 90 patients with > or = 10 nodes examined treated with surgery alone (Group B_S, n = 902) vs. surgery and adjuvant radiotherapy (Group B_S+R, n = 596). RESULTS For the two radiotherapy groups, patients with < 10 nodes (Group A_S+R) vs. > or = 10 nodes (Group B_S+R), there was no difference in overall survival (p = 0.14). In the two nonradiotherapy groups (A_S and B_S), there is a statistically significant decrease in overall survival for patients with < 10 nodes removed (p < 0.001, log-rank test). The optimal number of axillary nodes examined could be 8 nodes with adjuvant radiotherapy (p = 0.05, logrank test) and 12 nodes without adjuvant radiotherapy (p = 0.02, log-rank test). CONCLUSIONS The poorer prognosis of a lesser number of nodes resected was overcome partly by the use of radiotherapy, raising the possibility of micrometastases in lymph nodes not removed. The optimal number of axillary nodes examined could be 8 nodes with adjuvant radiotherapy and 12 nodes without adjuvant radiotherapy.

Abstract
BACKGROUND Most women with localized breast cancer have a choice between mastectomy and breast conserving surgery (BCS). Aside from clinical factors, this decision may be associated with surgeon and patient characteristics. We investigated the effect of surgeon characteristics on the BCS rate. METHODS We used the Surveillance, Epidemiology, and End Results-Medicare database to identify women >65 years, diagnosed with stages I-II BC, between 1991 and 2002, and used the Physician Unique Identification Number linked to the American Medical Association Masterfile to obtain information on surgeons. We investigated the association of patient demographic, tumor, and surgeon-related factors with receipt of BCS, using Generalized Estimating Equations to control for clustering. RESULTS Of 56,768 women with breast cancer, 30,006 (53%) underwent BCS, whereas 26,762 (47%) underwent mastectomy. Between 1991 and 2002, the proportion of patients undergoing BCS increased from 35% to 60%. In a multivariate analysis, patients who received BCS were younger, of higher SES, and had more favorable tumor characteristics. They were also more likely to be black and live in metropolitan areas. Women who underwent BCS were more likely to have surgeons who were female (OR = 1.40; 95% CI: 1.25-1.55), US-trained (OR = 1.12; 95% CI: 1.02-1.22), with a larger patient panel (OR = 1.29; 95% CI: 1.21-1.39), and completed training after 1975 (OR = 1.16; 95% CI: 1.08-1.25), than surgeons of patients who underwent mastectomy. CONCLUSIONS Surgeon characteristics, such as gender, training, year of graduation, and volume, are small but significant independent predictor of BCS. Efforts to differentiate whether these associations reflect patients' preferences, quality of physician training, surgeon attitudes, physician-patient communication, or other effects on decision-making are warranted.

Abstract
OBJECTIVES This study examined whether place and socio-economic status had differential effects on the survival of women diagnosed with breast cancer in Ontario during the 1980s and the 1990s. METHODS The Ontario Cancer Registry provided 29,934 primary malignant breast cancer cases. Successive historical cohorts (1986-1988 and 1995-1997) were, respectively, followed until 1994 and 2003. Diverse places were compared: the greater metropolitan Toronto area, other cities, ranging in size from 50,000 to a million people, smaller towns and villages, and rural and remote areas. Socio-economic data for each woman's residence at the time of diagnosis were taken from population censuses. RESULTS Very small cities (6%) with populations between 50,000 and 100,000 were the only places where breast cancer survival had advanced less compared to the province as a whole. Income gradients began to appear, however, in larger cities. Urban residents in the lowest income areas were significantly disadvantaged compared to the highest income areas during the 1990s, but not during the 1980s. CONCLUSION This historical analysis of breast cancer survival evidenced remarkably equitable advances across nearly all of Ontario's diverse places. The most likely explanation for such substantial equity seems to be Canada's universally accessible, single-payer, health care system.

Abstract
AIMS To determine whether excision of the tail of the breast usually by mastectomy or occasionally wide excision together with formal level 1 axillary node dissection (AND) for early breast cancer influences the quantity of harvested lymph nodes and the detection of axillary metastases. METHODS Multiple regression and binary logistic regression analysis were performed on lymph node harvest data for level 1 AND performed prior to the adoption of sentinel node biopsy during a five year period from 1997 to 2001 at the Leicestershire Breast Unit, comparing AND with and without excision of the tail of the breast. RESULTS One thousand six hundred and forty-eight level 1 ANDs were performed with a median node harvest of 14 (3-44). Multiple regression analysis identified that the total node harvest was increased by 1.03 nodes if the tail of the breast was excised (p<0.001) and this was independent of the effect on node count of node positivity. Operating surgeon and reporting pathologist did not influence node count. CONCLUSIONS The results of this study indicate that low axillary nodes may be missed by AND without excision of the tail of the breast and support the use of targeted sentinel node biopsy that should identify an involved node at any site.

Abstract
BACKGROUND Extracapsular extension of nodal tumor cells, although it is not a parameter of staging, has recently been shown to be correlated with the high number of metastatic lymph nodes in patients with axillary-positive breast cancer. It is suggested that the use of involved/examined lymph node ratio instead of the number of metastatic lymph nodes in axillary evaluation would obtain standardized prognostic data for patient management. This study investigated the association of the extracapsular extension with the lymph node ratio in a node-positive group of patients. PATIENTS AND METHODS Medical records of 170 patients with positive axillary status were retrospectively reviewed. Of these, 54 were extracapsular extension positive, and the remaining were extracapsular extension negative. A comparison was made between extracapsular extension-positive and extracapsular extension-negative groups with respect to some potential prognostic indicators. RESULTS Number of metastatic lymph nodes, number of examined lymph nodes, and involved/examined lymph node ratio were found to be significantly higher in patients with a presence of extracapsular extension. CONCLUSION The results suggest that the presence of extracapsular extension might force physicians to perform more aggressive adjuvant therapies and that the extracapsular extension could be a valuable parameter in the management of breast cancer because it has a strong relationship with the proven prognostic factors.

Abstract
AIM The aim of our study was to make evident the huge variability in lymph node dissection practice. MATERIAL AND METHODS Therefore a retrospective study was conducted on 330 patients assessed for cervical, axillary or groin dissections. In each case the authors collected the primary diagnosis and clinical stage indicating lymph node clearance, identity of the surgeon and the pathologist, surgical technique including skin incision and landmarks of tissue removal, size of the clearance, and number of lymph nodes removed. Correlations between diagnosis, surgeon's or pathologist's identity, size of the clearance and number of nodes were analyzed using non-parametric tests. RESULTS Standardized procedures as axillary dissections occurred few differences between surgeons. In groin or cervical dissections statistical differences were made evident with great technical variability. There was a positive correlation between size of the piece of lymphadenectomy and number of lymph nodes removed. CONCLUSION Standardized procedures as axillary dissections provide few variations. Cervical and especially groin dissections should be harmonized, published and taught harmoniously in schools of surgery. So the expression "regional lymph node clearance" would mean.

Abstract
PURPOSE With mammographic screening, the frequency of diagnosis of stage T1a,bN0M0 breast cancer has increased. Prognosis after locoregional therapy and benefit from adjuvant systemic therapy are poorly defined. We reviewed T1a,bN0M0 breast cancer cases registered in the Surveillance, Epidemiology, and End Results (SEER) Program to investigate the impact of prognostic factors on breast cancer-specific (BCSM) and non-breast cancer-related mortality. METHODS We identified T1a,bN0M0 breast cancer cases registered in the SEER Program from 1988 to 2001, and used the Kaplan-Meier product limit method to describe overall survival (OS). We estimated the probabilities of death resulting from breast cancer and from other causes, and analyzed associations of patient and tumor characteristics with OS, BCSM, and non-breast cancer-related mortality using the log-rank test, Cox proportional hazards models, and a competing-risk model. We constructed nomograms to assist physicians in adjuvant therapy decision making. RESULTS We identified 51,246 T1a,bN0M0 cases. Median follow-up was 64 months (range, 1 to 167 months). Median age at diagnosis was 65 years (range, 20 to 101 years). Ten-year probabilities of all-cause mortality and BCSM were 24% and 4%, respectively. Characteristics associated with increased probability of BCSM included age younger than 50 years at diagnosis, high tumor grade, estrogen receptor-negative status, progesterone receptor-negative status, and fewer than six nodes removed at axillary dissection. The constructed nomograms allow a comparison of predicted breast cancer-specific survival and non-breast cancer-specific survival in individual patients. CONCLUSION Overall, the prognosis of patients with T1a,bN0M0 breast cancer is excellent. However, subgroups of patients who are at higher risk of BCSM and who should be considered for adjuvant systemic therapy can be identified.

Abstract
With increased focus on quality assurance, a complete axillary lymph node dissection (ALND) has been defined as the removal of 10 or more lymph nodes (LN). The objective of this study was to determine which patient, physician, and geographic factors predict the adequacy of ALND in breast cancer patients. The University of Louisville Breast Cancer Sentinel Lymph Node Study is a multicenter, prospective study of 4,131 patients, all of whom had a sentinel node biopsy and completion ALND. Univariate and multivariate analyses were performed to determine which factors were independently associated with the removal of 10 or more LN. Of the 4,131 patients in this study, the median number of LN removed was 11 (range; 3-45). Ten or more LN were removed in 3,213 (77.8%) patients. The median patient age in this study was 60 (range; 27-100), with a median tumor size of 1.5 cm (range; 0.1-11.0 cm). On univariate analysis, patient age, tumor size, and palpability were correlated with adequacy of ALND. Academic affiliation and percentage of breast practice were significant physician factors predictive of adequacy of ALND. Both geographic region and community size were significantly correlated with adequacy of ALND. On multivariate analysis, patient age (p = 0.024), surgeon academic affiliation (p < 0.001), percentage breast practice (p < 0.001), and community size (p = 0.003) were significant determinants of adequacy of ALND. Younger patients were more likely to have an adequate ALND. Surgeons in academic practice had a higher rate of adequate ALND, as did those practicing in larger communities. Surgeons with a more breast experience had a lower rate of adequate ALND. Patient age, surgeon academic affiliation, and breast experience, as well as community size are all significant factors predictive of adequacy of ALND.

Abstract
BACKGROUND We examined the relationship between different expressions of positive axillary lymph nodes (PN) and the outcomes of node-positive breast carcinoma patients to determine the best predictor(s) among these expressions and to assess whether anatomic high level involvement is an independent prognostic factor. STUDY DESIGN In this retrospective study, the primary endpoints were distant recurrence (DR), locoregional recurrences (LRR), and disease-free survival (DFS). Univariate and multivariate prognostic factor analyses were carried out using survival and regression methods in the data of 704 patients with PN. RESULTS In multivariate analysis, the number of PN, ratio of PN, log odds of PN, and level III (L-III) involvement, separately, were significant factors for DR in addition to age, tumor size, and lymphovascular invasion (LVI). In the final model including all expressions of nodal involvement, age (continuous P = 0.001; hazard ratio [HR]: 0.98; 95% confidence Interval [95% CI]: 0.96-0.99), tumor size (continuous: P < 0.0001; HR: 1.3; 95% CI, 1.2-1.5), LVI (yes vs. no: P = 0.005; HR: 1.6; 95% CI, 1.2-2.2), and ratio of PN (continuous: P = 0.02; HR: 1.03; 95% CI, 1.01-1.06) were the independent prognostic factors for DR. For LRR, ratio of PN (continuous: P = 0.001; HR: 1.02; 95% CI, 1.01-1.03) was the most important factor in addition to age (continuous: P = 0.02; HR: 0.98; 95% CI, 0.97-0.99) and tumor size (continuous: P = 0.04; HR: 1.3; 95% CI, 1.1-1.6). When patients were stratified by number categories of PN (1-3 vs. 4-9 vs. >/= 10), there was no difference between DFSs of patients with and without L-III involvement. In contrast, when patients were stratified by L-III involvement, DFSs according to the number categories were statistically different. CONCLUSIONS Ratio of PN was more valuable than number of PN for predicting outcome in node-positive breast carcinoma patients. Level III involvement was not an independent prognostic indicator either for locoregional or for distant recurrences.

Abstract
PURPOSE Number of positive lymph nodes in the axilla and pathologic lymph node status (pN) have a great impact on staging according to the current American Joint Committee on Cancer staging system of breast carcinoma. Our aim was to define whether the total number of removed axillary lymph nodes influences the pN and thus the staging. METHODS AND MATERIALS The records of 798 consecutive invasive breast cancer patients with T1-3 tumors and positive axillary lymph nodes who underwent modified radical mastectomy between 1999 and 2005 in our hospital were reviewed. The total number of removed nodes were grouped, and compared with the patient and tumor characteristics and the influence of the number of nodes removed on the staging was analyzed. RESULTS The proportion of patients with > or =4 positive nodes (59%), and pN3 status (51%) were the highest in the group with 21-25 nodes removed. Compared with patients with 1-20 nodes removed, the proportion of patients with > or =4 positive nodes (52%), and pN3 status (46%) were significantly higher in those with more than 20 nodes removed. Although the proportion of Stage IIA and IIB decreased, the proportion of Stage IIIA and IIIC increased in patients with >20 nodes removed compared with those with 1-20 nodes removed. CONCLUSIONS In patients with axillary node-positive breast carcinoma, staging is highly influenced by total number of removed nodes. Levels I-III axillary dissection with more than 20 axillary lymph nodes removed could lead to more effective adjuvant chemotherapy and increases substantially the proportion of patients to receive radiotherapy.

Abstract
AIMS To determine if the number of removed lymph nodes in radical hysterectomy with lymphadenectomy (RHL) influences survival of patients with early stage cervical cancer and to analyze the relation of different factors like patient age, tumour size and infiltration depth with the number of nodes examined in node-negative early stage cervical cancer patients. METHODS Of consecutive patients, who underwent RHL between January 1984 and April 2005, 331 had negative nodes (group A) without adjuvant therapy and 136 had positive nodes (group B). The Kaplan-Meier method and Cox regression model were used to detect statistical significance. Factors associated with excision of nodes were confirmed with linear regression models. RESULTS The median number of removed nodes was 19 and 18 for group A and group B, respectively. There was no significant relationship between the number of removed nodes and the cancer specific survival (CSS) or disease free survival (DSF) for patients of group A (p=0.625 and p=0.877, respectively). The number of removed nodes in group B was not significantly associated with the CSS (p=0.084) but it was for the DSF (p=0.014). Factors like patient age, tumour size and infiltration depth were not associated with the number of nodes. CONCLUSIONS No relation was found between the number of negative nodes examined after RHL for the treatment of early stage cervical cancer and CSS or DFS. However, a higher amount of removed lymph nodes leaded to a better DFS for patients with positive nodes. It is suggested that patients with positive nodes benefit from a complete pelvic lymphadenectomy and a sufficient yield of removed nodes.

Abstract
BACKGROUND The aim of the study was to determine whether the number of lymph nodes removed at axillary dissection is associated with recurrence and survival in node-negative breast cancer (NNBC) patients. PATIENTS AND METHODS We retrospectively reviewed the medical records of 1606 women with pathologically node-negative T1-T3 invasive breast cancer. Median follow-up was 61 months (range 2-251). Potential prognostic factors assessed included: number of axillary lymph nodes examined, age, menopausal status, tumor size, histological type, tumor grade, estrogen receptor(ER), progesterone receptor (PR) and HER2. RESULTS At 5 years, relapse-free survival (RFS) rate was 85% and breast cancer-specific survival (BCSS) rate was 94%. In univariate analysis, factors significantly associated with lower RFS and BCSS were: fewer than six lymph nodes examined (RFS, P = 0.01; BCSS, P = 0.007), tumor size >2 cm, grade III, negative ER or PR. Statistically significant factors for lower RFS and BCSS in multivariate analysis were: fewer than six lymph nodes examined [RFS, hazard ratio (HR) 1.36, P = 0.029; BCSS, HR 1.87, P = 0.005], tumor size >2 cm, tumor grade III and negative PR. CONCLUSIONS Examination of fewer than six lymph nodes is an adverse prognostic factor in NNBC because it could lead to understaging. Six or more nodes need to be examined at axillary dissection to be confident of a node-negative status. This may be useful, in conjunction with other prognostic factors, in the assessment of NNBC patients for adjuvant systemic therapy.

Abstract
BACKGROUND Retrieval of fewer than 10 lymph nodes at axillary dissection (ALND) for breast cancer can represent anatomic variation or inadequate dissection. We postulated that despite aggressive ALND, a lower lymph node count is more frequent after neoadjuvant chemotherapy. METHODS Patients who received neoadjuvant chemotherapy followed by ALND were compared with patients who received surgery first. All patients received a level I and II ALND at a single institution by one of the breast surgeons. The number of nodes retrieved at ALND was dichotomized into categories (< 10 and > or = 10), and compared using Fisher exact test. RESULTS A total of 143 neoadjuvant and 170 surgery-first patients were studied. Patients treated with neoadjuvant chemotherapy were significantly more likely to have fewer than 10 lymph nodes retrieved at ALND than were the surgery-first patients (19/143 or 13% vs. 6/170 or 4%, P = .003). CONCLUSIONS A low lymph node count is more common in patients after treatment with neoadjuvant chemotherapy and should not be assumed to represent an incomplete ALND.
