Objective To investigate the nonsentinel lymph nodal (NSLN) status in 1-2 sentinel lymph node positive early breast cancer and to compare with that in Z0011 ALND group.Methods A total of 234 T1,T2 invasive breast cancer with 1-2 positive sentinel lymph nodes were collected in Henan Tumorr Hospital from Jul 2010 to Aug 2014.The data was compared with that of Z0011 ALND group.Results 234 female patients were enrolled.76 cases had non sentinel lymph node metastases.The proportion of 1 and 2 sentinel lymph node metastases was 75.2％ and 24.8％,respectively.The number of positive sentinel lymph nodes and that of negative ones were independent predictors of the non sentinel lymph node status (all P ＜ 0.05).Menstrual status,hormone receptor,Ki67 level and HER2 were not associated with nonsentinel lymph node metastasis (all P ＞ 0.05).They had nonsentinel lymph node positive rate (P ＞ 0.05) similar to that of Z0011 ALND group.Conclusious The number of sentinel lymph nodes and negative sentinel lymph nodes were associated with nonsentinel lymph node metastasis in the 1-2 sentinel lymph positive early stage breast cancer.Those patients had similar positive nonsentinel lymph node rate to that of Z0011 ALND group.

Objective:To investigate the correlation between ipsilateral metastatic supraclavicular lymph nodes(ISLN) pathologically complete response (spCR) and the prognosis in breast cancer after neoadjuvant chemotherapy(NAC) and lymphadenectomy.Methods:Clinical data of 234 breast cancer patients with ISLN at the time of diagnosis and receiving supraclavicular lymph node dissection following NAC were retrospectively analyzed.Results:All patients were female, with a median age of 52 years. The spCR rate was 52.6%. Multivariate analysis showed that the expression level of Ki67, the pathological status of breast and axillary nodes and the dissection number of supraclavicular lymph node were independent relate factors for spCR (all P<0.05). After a median follow-up of 16.6 months, the risk of recurrence and metastasis in the spCR group was 51%. It was lower than that in the non-spCR group ( HR=0.49, 95% CI 0.27-0.89, P=0.020). It was mainly manifested in hormone receptor negative patients. Supraclavicular spCR was an independent prognostic factor for DFS. Conclusions:The expression level of Ki67, pathological state of breast and axillary node and the dissection number of supraclavicular lymph node were independent related factors of spCR, which was also an independent predictor of DFS.

Objective:To investigate the prognostic value of molecular subtypes in patients with resected invasive breast cancer.Methods:Between 2015 and 2018 7 869 patients with invasive breast cancer after undergoing surgery were included in this analysis. Breast cancer was classified into four subtypes according to the status of hormone receptor (HR) and HER2: HR+/HER2-, HR+/HER2+, HR-/HER2+, and HR-/HER2-. Kaplan-Meier curves and COX regression were used to compare disease-free survival (DFS) and overall survival (OS) among different subtypes.Results:The 5-year DFS and OS were 86.30% and 94.29%, respectively. Proportions of HR+/HER2-、HR+/HER2+、HR-/HER2+ and HR-/HER2- were 52.9%、17.5%、14.1%和15.5%, respectively. The 5-year DFS of HR+/HER2- subtype (88.12%) was higher than HR+/HER2+ (84.67%, P=0.026), HR-/HER2+ (84.19%, P<0.001) and HR-/HER2- (83.70%, P<0.001). The 5-year OS of HR+/HER2- (95.38%) was not different from HR+/HER2+ (95.17%, P=0.187), while it was higher than that of HR-/HER2+ (92.26%, P<0.001) and HR-/HER2- (91.69%, P<0.001). Subtype was still a significant factor regarding DFS and OS in multivariable analyses adjusting for age, sex, stage, Ki67, types and time of surgery. The DFS ( P=0.257) and OS ( P=0.511) was not different between HR-/HER2+与HR+/HER2- subtypes, while HR-/HER2+ and HR-/HER2- patients had worse DFS ( P<0.05) and OS ( P<0.05) than that with HR+/HER2-. Conclusions:Molecular subtype is a significant independent prognostic factor for DFS and OS in operable invasive breast cancer. HR+ subtypes have better prognosis compared with HR- subtypes. The DFS and OS were not different between HR+/HER2- and HR+/HER2+, or between HR-/HER2+ and HR-/HER2-.

OBJECTIVETo investigate the predictive factors affecting sentinel lymph node status in early breast cancer patients.

METHODSClinicopathological data of 1 038 patients with early breast cancer, who underwent sentinel lymph node biopsy in Henan Tumor Hospital between July 2010 and August 2013, were reviewed. Logistic regression analysis was performed to identify the relevance of clinicopathological features with sentinel lymph node metastases.

RESULTSThis group was consisted of 1 038 female patients with an average of 48.6 years. Positive sentinel lymph nodes were found in 22.9% (238/1 038) of the patients. The average number of sentinel lymph nodes removed by surgery was 3.8. Tumor size, tumor location, histopathology, ER/PR status and Ki-67 level were significantly correlated with SLN metastasis(P < 0.05 for all). All the above factors but Ki-67 level were significant independent predictors for SLN metastasis(P < 0.01 for all).

CONCLUSIONNegative hormone receptor status, invasive cancer of non-specific histopathological type, tumor size >2 cm, and tumor location in the outer upper quadrat are independent predictive factors of sentinel lymph node metastasis in patients with early breast cancer.

Objective: To investigate the influence of lumpectomy on axillary lymph node status of breast cancer patients. Methods: The clinical data of 738 invasive breast cancer patients with non-palpable axillary lymph node and sentinel lymph node (SLN) biopsy from November 2011 to August 2013 in Henan Provincial Cancer Hospital were collected and retrospectively analyzed. Among them, 136 patients underwent preoperative lumpectomy (lumpectomy group) and 602 patients underwent puncture biopsy only (biopsy group). The difference of axillary lymph node status and positive ratio of SLN detected by color Doppler ultrasound were compared between these two groups. Results: Among the 738 breast cancer patients, the axillary lymph nodes of 444 (60.2%) cases could be detected by ultrasound. Among them, 92 cases belonged to lumpectomy group, significantly less than 352 cases of biopsy group (P=0.048). Among the patients with ultrasound-visible lymph nodes, the proportion of the biggest diameter of axillary lymph node >1 cm of lumpectomy group or biopsy group was 58.7% (54/92) or 52.8% (186/352), respectively, without significant difference (P=0.316). The proportion of patients with the ratio of long diameter to short diameter <2 of lumpectomy group or biopsy group was 37.0% (34/92) or 38.6% (136/352), respectively, with marginal difference (P=0.768). The positive rate of SLN of lumpectomy group or biopsy group was 23.5% (32/136) or 26.9% (162/602), respectively, without significant difference (P=0.419). The incidence rate of the ultrasound visible axillary lymph nodes of patients whose postoperative time ≤ 7 days or > 7days was 71.1% (64/90) or 60.9% (8/46), respectively, without significant difference (P=0.227). However, the positive rate of SLN of these two groups was 28.9% (26/90) and 13.0% (6/46), respectively, with significant difference (P=0.039). The number of ultrasound visible axillary lymph nodes, the biggest diameter of axillary lymph nodes and the ratio of the long diameter to short diameter <2 were substantially correlated with the positive rate of SLN (P<0.05). Conclusions The incidence rate of ultrasound visible axillary lymph node in the patients with lumpectomy is higher than that of patients with puncture biopsy only. The positive rate of SLN of the patients with a long postoperative time is lower than that of patients with a short postoperative time, even though the axillary lymph nodes are ultrasound visible.
