| description | There is an enhanced immune response in patients with breast cancer after the use of chemotherapy. The objective of this study was therefore to investigate alterations in the number of peripheral lymphocytes in patients with breast cancer after neoadjuvant chemotherapy (NC) and the relationship with prognosis.
Thirty women were analyzed. Their UICC staging was IIb (only T3N0 included) and III (N3 not included). Sample analysis was performed using flow cytometry before the first cycle and 18 to 21 days after the last cycle of NC. The lymphocyte subsets studied were: T (CD3, CD4, CD8), B (CD19, CD23), natural killer (NK) (CD56, CD16), and interleukin-2 (CD25). CD3, CD56, CD8, and CD16 lymphocytes were analyzed with double marking. After x = 3.8 +/- 1.3 cycles of 5-fluorouracil, epirubicin and cyclophosphamide (FEC), 16 patients showed a complete or partial response (group 1). After three cycles 14 showed no response or tumor progression (group 2). A control group of healthy women was used for pretreatment analysis.
Before NC there was a significant increase in B lymphocytes and NK cells in comparison to the control group. After NC there was a significant percentage increase in CD3, CD4, CD8, CD25 and CD3+CD56+ cells and a decrease in CD19, CD23, CD56, CD16 and CD16+CD8+ cells. There was a significant fall in the absolute number of CD4, CD19, CD23, CD56, CD16 and CD16+CD8+ lymphocytes and an increase in CD3+CD56+ lymphocytes. Before NC the ratio CD4/CD8 in group 1 was 2.25 +/- 0.5 and in group 2 it was 1.79 +/- 0.5 (P |

Before NC the ratio CD4/CD8 in group 1 was 2.25 +/- 0.5 and in group 2 it was 1.79 +/- 0.5 (P <0.05).
Patients with advanced breast cancer showed increases in B and NK lymphocytes. Neoadjuvant chemotherapy (FEC) caused an increase in CD3+CD56+ and a decrease in B lymphocytes. Patients with an increased CD4/CD8 ratio have a better chance of responding to neoadjuvant chemotherapy.</description><identifier>ISSN: 0300-8916</identifier><identifier>EISSN: 2038-2529</identifier><identifier>DOI: 10.1177/030089160008600507</identifier><identifier>PMID: 11130570</identifier><language>eng</language><publisher>United States</publisher><subject>Adult ; Antigens, CD - drug effects ; B-Lymphocyte Subsets - drug effects ; Breast Neoplasms - drug therapy ; Breast Neoplasms - immunology ; Breast Neoplasms - pathology ; Carcinoma, Ductal, Breast - drug therapy ; Carcinoma, Ductal, Breast - immunology ; Carcinoma, Ductal, Breast - pathology ; CD4-CD8 Ratio ; Chemotherapy, Adjuvant ; Disease Progression ; Female ; Humans ; Interleukin-2 - biosynthesis ; Killer Cells, Natural - drug effects ; Lymphocyte Count ; Lymphocyte Subsets - drug effects ; Middle Aged ; Neoadjuvant Therapy ; Neoplasm Staging ; T-Lymphocyte Subsets - drug effects</subject><ispartof>Tumori, 2000-09, Vol.86 (5), p.403-407</ispartof><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c299t-c817c1798f3973c222b3880e4ca373ba524a3227f53f922068671581c7d263503</citedby><cites>FETCH-LOGICAL-c299t-c817c1798f3973c222b3880e4ca373ba524a3227f53f922068671581c7d263503</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,27924,27925</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/11130570$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Murta, E F</creatorcontrib><creatorcontrib>de Andrade, J M</creatorcontrib><creatorcontrib>Falcão, R P</creatorcontrib><creatorcontrib>Bighetti, S</creatorcontrib><title>Lymphocyte subpopulations in patients with advanced breast cancer submitted to neoadjuvant chemotherapy</title><title>Tumori</title><addtitle>Tumori</addtitle><description>There is an enhanced immune response in patients with breast cancer after the use of chemotherapy.
