The current guidelines and consensus recommend a sequential schedule of CT and ET for patients with hormone receptor-positive (HR+) BC. However, with the continuous introduction of new endocrine drugs, the question of whether the simultaneous administration of CT and ET is superior to sequential therapy has surfaced again as a hot topic of clinical concern. Recent studies have shown that the combination of certain chemotherapeutic agents with endocrine drugs has a synergistic effect. This review aims to summarize the new advances achieved in recent years on the old topic of CT combined with ET in the treatment of BC.","PeriodicalId":10197,"journal":{"name":"Clinical breast cancer","volume":null,"pages":null},"PeriodicalIF":3.1,"publicationDate":"2024-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142215892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Standard SLNB entails removing all lymph nodes (LN) that have a radioactive count > 10% of the most radioactive node, contain blue dye or are palpably suspicious. In this study, we hypothesize that judicious SLNB with attempt to remove only the node with the highest radioactive count provides sufficient pathologic information while minimizing morbidity. A single institution prospective database was retrospectively reviewed to identify women with DCIS who underwent mastectomy and SLNB between 2010 and 2022. Patient characteristics, number of SLNs retrieved, pathologic results and long-term upper extremity complications were analyzed. A total of 743 LNs were removed in 324 pts. Median (IQR) age was 62 (51-70) years. Dual tracer technique, with technetium-99m labeled radiocolloid and blue dye, was used in 311 (96%) pts, whereas single agent (radioisotope or blue dye alone) was utilized in 9 (2.8%) and 4 (1.2%) patients, respectively. Median (IQR) number of SLN removed was 2 (1-3) (range 1-9). In 99% of cases, the SLN with the highest radioactive count was identified among the first 3 dissected LNs. Final pathology revealed upstaging to invasive cancer in 27.5% ( = 89) of the breasts and nodal positivity in 1.9% ( = 6) of the patients. In all 6 cases, metastatic disease was identified in the LN with highest radioactive count among the LNs retrieved. No additional metastatic nodes were identified after > 3 SLN had been removed. At median follow-up of 57 (range 28-87) months, 8.3% ( = 27) of pts complained of long-term upper extremity symptoms. 7.1% (23 pts) were referred to physical therapy for symptoms such as swelling, fullness, heaviness, stiffness, or sensory discomfort in the upper extremity and/or axillary cording. Long-term upper extremity complications were higher when > 3 SLNs compared to ≤ 3 SLNs were removed (10.4% vs. 6.5%, = .005). In this cohort of patients with DCIS undergoing mastectomy who were upstaged on final pathology to node positive invasive cancers, the SLN with the highest radioactive count provided sufficient information for axillary staging. Acknowledging that the “hottest” LN is not always the first 1 removed, these data support an increased likelihood of developing long-term complications when more than 3 SLNs are removed. Rather than comprehensive removal of all SLNs meeting the standard “10% rule,” prioritizing the sequence of removal to the highest count provides the same prognostic information with reduced morbidity.","PeriodicalId":10197,"journal":{"name":"Clinical breast cancer","volume":null,"pages":null},"PeriodicalIF":3.1,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142215914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
