542 Background: Neoadjuvant chemotherapy is the treatment of choice in patients with T4a-c and inflammatory (T4d) breast cancer. However, data on large-scale, multicentre, prospective trials are missing. In the GeparTRIO study (SABCS 2006, abstr. 42) 278 of 2,090 patients with cT4a-c or T4d tumors were included as a separate stratum for inoperable disease for a prospectively planned analysis. Methods: Patients were treated with 2 cycles TAC (docetaxel 75 mg/m2, doxorubicin 50 mg/m2, cyclophosphamide 500 mg/m2, q d 21). If tumor reduction was >50%, patients were randomized to receive 4 or 6 additional TAC cycles. If tumor reduction was less, patients were randomized to 4 additional TAC cycles or to 4 NX cycles (vinorelbine 25 mg/m2 day 1 + 8, capecitabine 2,000 mg/m2 day 1 14, q21). Efficacy endpoints were pCR-rate (no invasive and no non-invasive residuals in breast and lymph nodes) (primary), clinical response before surgery and breast conserving therapy (BCT) rate (secondary). Results: 95 (4.6%) T4d, 183 (8.9%) cT4a-c, and 1,767 (86.4%) T1–3 tumors were registered in GeparTRIO within 36 months. Patients with inoperable/operable tumors had a median age of 53.9/49.0 years, median cT size: 7.0/4.0cm, cN+: 75.6/52.0%, ductal: 76.3/78.4%, lobular: 14.0/13.5%, multiple lesions: 28.5/19.5%, grade 3: 34.8/39.9%, hormone receptor (HR) neg: 24.7/36.6%, HER-2 pos: 41.0/35.5%. Response rates for T4d, T4a-c, T1–3 were 8.4, 10.9, 17.5% (pCR, p=0.007), 36.7, 59.4, 72.6% (palpation after 2 cycles TAC, p<0.0001), 64.2, 62.3, 77.8% (palpation before surgery, p<0.0001), 52.6, 51.9, 67.4% (ultrasound before surgery, p<0.0001). BCT was performed in 12.6, 31.7, 69.5% (p<0.0001). Response after two cycles, negative HR content, young age, high grade, ductal type, but not tumor stage or size, were independent predictors for pCR in the total population. Conclusions: Inflammatory and cT4a-c breast carcinomas, compared to cT1–3 tumors, show less favorable tumor characteristics but a comparable pattern of response to TAC/NX. These patients do not need separate neoadjuvant trials. [Table: see text]

PurposeNeoadjuvant chemotherapy followed by mastectomy is the treatment of choice in patients with inflammatory breast cancer (IBC) or locally advanced breast cancer (LABC), but it is considered less effective in these diseases than in operable breast cancer (OBC). We report a prospective comparison of the GeparTrio trial of patients with IBC (cT4 days) or LABC (cT4a-c or cN3; stage IIIB or IIIC) and patients with OBC (cT2-3).Patients and MethodsParticipants were stratified by stage and were randomly assigned to six or eight cycles of docetaxel/doxorubicin/cyclophosphamide (TAC) or to two cycles of TAC followed by four cycles of vinorelbine/capecitabine. We present results of a secondary aim of the study, which was to compare pathologic complete response (pCR; ie, no remaining invasive/noninvasive tumor in breast and lymph nodes) in different stage groups.ResultsA total of 287 patients with IBC (n = 93) or LABC (n = 194) and 1,777 patients with OBC were entered onto the trial. At baseline, parameters were as follows for the three types of cancer, respectively: median tumor sizes: 8.0 cm, 7.0 cm, and 4.0 cm (P < .001); multiple lesions: 31.2%, 27.3%, and 19.6% (P < .001); nodal involvement: 86.6%, 71.2%, and 51.6% (P < .001); grade 3: 44.4%, 30.4%, and 39.9% (P = .178); lobular-invasive type: 7.5%, 17.5%, and 13.3% (P = .673); negative hormone receptor status: 38.0%, 20.0%, and 36.4% (P = .008); and positive human growth factor receptor 2 status: 45.1%, 38.9%, and 35.7% (P = .158). Response rates for IBC, LABC, and OBC, respectively, were 8.6%, 11.3%, and 17.7% for pCR (P = .002); 71.0%, 69.6%, and 83.4% for overall response by physical or sonographic examination (P < .001); and 12.9%, 33.0%, and 69.9% for breast conservation (P < .001). All P values were for IBC and LABC versus OBC. However, tumor stage itself was not an independent predictor for pCR in multivariable analysis (odds ratio, 1.51; 95% CI, 0.88 to 2.59; P = .13).ConclusionNo evidence of a difference in response to neoadjuvant chemotherapy was found by tumor stage when analysis was adjusted for baseline characteristics.

Neoadjuvant chemotherapy (NAC) is becoming the standard of care for locally advanced breast cancer, aiming to reduce tumor size before surgery. Unfortunately, less than 30% of patients generally achieve a pathological complete response and approximately 5% of patients show disease progression while receiving NAC. Accurate assessment of the response to NAC is crucial for subsequent surgical planning. Furthermore, early prediction of tumor response could avoid patients being overtreated with useless chemotherapy sections, which are not free from side effects and psychological implications. In this review, we first analyze and compare the accuracy of conventional and advanced imaging techniques as well as discuss the application of artificial intelligence tools in the assessment of tumor response after NAC. Thereafter, the role of advanced imaging techniques, such as MRI, nuclear medicine, and new hybrid PET/MRI imaging in the prediction of the response to NAC is described in the second part of the review. Finally, future perspectives in NAC response prediction, represented by AI applications, are discussed.

Our previous study indicated that a high amount of visceral adipose tissue was associated with poor survival outcomes in patients with early breast cancer who received neoadjuvant chemotherapy. However, inconsistency was observed in the prognostic role of body composition in breast cancer treatment outcomes. In the present study, we aimed to validate our previous research by performing a comprehensive body composition analysis in patients with a standardized clinical background. We included 198 patients with stage III breast cancer who underwent neoadjuvant chemotherapy between January 2007 and June 2015. The impact of body composition on pathologic complete response and survival outcomes was determined. Body composition measurements had no significant effect on pathologic complete response. Survival analysis showed a low ratio of total visceral adipose tissue to subcutaneous adipose tissue (V/S ratio ≤ 34) was associated with shorter overall survival. A changepoint method determined that a V/S ratio cutoff of 34 maximized the difference in overall survival. Our study indicated the prognostic effect of body composition measurements in patients with locally advanced breast cancer compared to those with early breast cancer. Further investigation will be needed to clarify the biological mechanism underlying the association of V/S ratio with prognosis in locally advanced breast cancer.
