Abstract PurposeTo compare the efficacy and safety of high dose-intensity combination of methotrexate, vinblastine, adriamycin and cisplatin (HD MVAC) with gemcitabine plus cisplatin (GC) as a neoadjuvant chemotherapy (NAC) in muscle-invasive bladder cancer (MIBC) or locally advanced upper tract urothelial cancer (UTUC). Patients and MethodsA retrospective analysis was conducted for patients with UC (cT2-4aN0-1M0) who received NAC from January 2011 and December 2017 at Asan Medical Center. Pathologic complete response (pCR), down-staging (<ypT2 and no N upstaging), disease-free survival (DFS), OS and safety were compared for each regimen. ResultsOut of a total of 277 patients, 176 patients received GC and 41 patients received HD MVAC. With the exception of age (patients receiving GC were younger; p=0.002), other baseline characteristics were well balanced between groups. pCR rates were 27.0% for GC and 22.6% for HD MVAC (p=0.62), and down-staging rate was 50.8% for GC and 58.1% for HD MVAC (p=0.47). There were no differences in OS (72.1% vs 73.1% for GC vs HD MVAC; p=0.58) and DFS (54.9% vs 63.3% for GC vs HD MVAC; p=0.21) at 3 years. HD MVAC with prophylactic G-CSF was associated with a higher incidence of febrile neutropenia (p<0.001) than GC. The NAC regimen was not an independent prognostic factor for OS. ConclusionsOncologic outcomes were not significantly different between the GC and HD MVAC when used as NAC in MIBC/UTUC.

276 Background: Continuous exposure to cyclophosphamide (C) can result in selective cytotoxicity for endothelial cells, followed by antiangiogenic effects on tumor cells. In this study we analyzed the pathological complete response (pCR) rate in a cohort of patients (p) diagnosed with locally advanced breast cancer (LABC) treated with neoadjuvant chemotherapy (CT) based on anthracyclines and taxanes, depending on the route of administration of C (intravenous (IV) and oral arms). Methods: We retrospectively studied a consecutive series of p. with LABC treated with neoadjuvant CT in 2 hospitals in Asturias. The regimens used were CE100F, AC (regimens with IV C) or oral CAF (C 100mg/m2/day orally x 14 days, doxorubicin 30 mg/m2 day 1 and 8 and 5-FU 500 mg/m2 days 1 and 8 every 28 days) x 4 cycles. The anthracycline regimen was followed by weekly paclitaxel or docetaxel every 3 weeks. If HER2 overexpression, trastuzumab was given in combination with the taxane. Results: We identified 105 p., 65 of them treated with oral C and 40 with IV C (CEF 3 patients and AC 37 patients). The median age was slightly higher in the p. treated with C IV (52.2 vs. 47.7, p = 0.022), which also received a higher number of cycles (7.1 vs. 6.7, p = 0.025), although there were no significant differences in the anthracycline dose intensity (93% vs 89%, p = 0.093). There were no significant differences in tumor size, lymph node involvement, grade, estrogen receptor (ER) or HER2. The rate of pCR was significantly higher in p. receiving oral C (33.8% vs 10%, p = 0.004). Grade 3, negative estrogen receptors and HER2 were also significantly associated with a higher rate of pCR. On multivariate analysis only oral C was an independent factor associated with pCR. With a median follow up of 27.3 months (95% CI 24 to 30.6), there have been 10 recurrences (15.4%) in the continuous arm and 9 (22.5%) in the standard arm, without significant differences in disease free survival. Conclusions: Our results suggest that the pCR rate can be higher using oral C in the neoadjuvant treatment of LABC based on anthracyclines and taxanes. This hypothesis should be confirmed in a randomized and prospective study.

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.

Abstract   In recent years, immune checkpoint inhibitors (ICIs) have shown promising results in the treatment of ESCC. More than 20 phase II clinical trials have been launched to explore combinations of ICIs in the neoadjuvant setting for ESCC. Based on our phase II clinical trial, a two-arm phase III trial was launched in our Hospital. Methods A two-arm phase III trial was launched in April 2020 in our Hospital. Patient recruitment will be completed within 18 months. The primary endpoint is event-free survival (EFS). The secondary endpoints include pathologic complete response (pCR), disease-free survival (DFS) rate, overall response rate (ORR), R0 resection rate, major pathologic response (MPR), adverse events (AEs), complication rate and quality of life (QOL). A biobank of pretreatment, resected tumor tissue and paired blood samples will be built for translational research in the future. Results Until Dec. 2021, one hundred and twenty ESCC patients recruited in the trial. The trial is ongoing. Conclusion This RCT directly compares NAC with neoadjuvant toripalimab plus chemotherapy in terms of EFS for locally advanced ESCC. The results may usher in a new era of resectable ESCC treatment.

The aim of the study: to increase the frequency of achieving pathologic complete response and increase disease-free survival in the investigational group of patients with locally advanced rectal cancer T3(MRF+)–4N0–2M0 by developing a new strategy for neoadjuvant therapy.Materials and methods. In total, 414 patients were assigned to treatment. Control group I included 89 patients who underwent radiotherapy (RT) 52–56 Gy/26–28 fractions with concurrent capecitabine twice daily 5 days per week. Control group II included 160 patients who underwent RT 52–56 Gy/26–28 fractions with concurrent capecitabine twice daily 5 days per week and oxaliplatin once a week, during the course of RT. Study group III consisted of 165 patients. This group combined RT 52–56 Gy/26–28 fractions with concurrent capecitabine twice daily 5 days per week and additional consecutive CapOx cycles. This group was divided into 2 subgroups: subgroup IIIa included 106 patients with consolidating chemotherapy (after CRT); subgroup IIIb included 59 patients who underwent “sandwich” treatment. Therapy consisted of conducting from 1 to 2 cycles of induction CapOx (up to CRT) and from 1 to 2 cycles of consolidating CapOx with an interval of 7 days. In the interval between the courses of drug therapy, RT 52–56 Gy/26–28 fractions was performed. According to the results of the control examination, further treatment tactics were determined. The primary end points were 5-year disease-free survival and the achievement of a pathologic complete response.Results. Pathologic complete response was significantly more often recorded in patients in the investigational group III (17.48 %; p = 0.021) compared with control groups (7.95 % in the I group and 8.28 % in the II group). 5-year disease-free survival in patients in the study groups was: 71.5 % in the III group, 65.6 % in the II group and 56.9 % in the I group.Conclusion. The shift in emphasis on strengthening the neoadjuvant effect on the tumor and improving approaches to drug therapy regimens have significantly improved disease-free survival of patients with locally advanced rectal cancer.

Systemic treatment for triple negative breast cancer (TNBC: negative for the expression of estrogen receptor and progesterone receptor and HER2 amplification) has been limited to chemotherapy options. Neoadjuvant chemotherapy induces tumor shrinkage and improves the surgical outcomes of patients with locally advanced disease and also identifies those at high risk of disease relapse despite today’s standard of care. By using pathologic complete response as a surrogate endpoint, novel treatment strategies can be efficiently assessed. Tissue analysis in the neoadjuvant setting is also an important research tool for the identification of chemotherapy resistance mechanisms and new therapeutic targets. In this paper, we review data on completed and ongoing neoadjuvant clinical trials in patients with TNBC and discuss treatment controversies that face clinicians and researchers when neoadjuvant chemotherapy is employed.
