Background. The impact of postmastectomy radiotherapy (PMRT) in patients receiving neoadjuvant chemotherapy (NAC) is unclear. The purpose of this study is to identify the patients who may benefit from PMRT. Methods. We retrospectively analysed patients with clinical stage II-III breast cancer who underwent NAC and modified radical mastectomy at our centre from 2007 to 2015. We investigated the relationship amongst locoregional recurrence rate (LRR), disease-free survival (DFS), and clinical pathological characters. Results. A total of 554 patients were analysed in this study. The median follow-up time was 65 months. Amongst the patients, 58 (10.5%) had locoregional recurrence, 138 (24.9%) had distant metastasis, and 72 (13.0%) patients died. The 5-year cumulative incidence of LRR and DFS was 9.2% and 74.2%, respectively. A total of 399 (72%) patients received PMRT and 155 (28%) did not. The 5-year LRR of the patients with PMRT (7.3% vs. 14.1%, P = 0.01 ) decreased significantly. We found that PMRT was an independent prognostic factor of LRR and DFS. Patients with the persistent involvement of 1–3 lymph nodes (ypN1) and more than 4 positive lymph nodes (ypN2-3) had a better outcome after PMRT than those without. However, the LRR and DFS of patients with negative lymph nodes at the time of surgery (ypN0) and who received PMRT showed no significant benefits. Amongst all patients with the three molecular subtypes of breast cancer, patients with triple-negative breast cancer had the highest pathological complete response rate but the worst prognosis ( P = 0.001 ). Conclusion. Results showed that PMRT significantly reduced the LRR of patients with clinical stage II-III breast cancer after receiving NAC and mastectomy. YpN0 patients derived no local control or survival benefit after receiving PMRT, whereas those with ypN1 and ypN2-3 could obviously benefit from PMRT.

PURPOSE: To define clinical and pathologic predictors of local-regional recurrence (LRR) for patients treated with neoadjuvant chemotherapy and mastectomy without radiation. PATIENTS AND METHODS: We analyzed the outcome of the 150 breast cancer cases treated on prospective institutional trials with neoadjuvant chemotherapy and mastectomy without postmastectomy radiation. Clinical stage at diagnosis was I in 1%, II in 43%, IIIA in 23%, IIIB in 25%, and IV in 7%. No patient had inflammatory breast cancer. RESULTS: The median follow-up period of surviving patients was 4.1 years. The 5- and 10-year actuarial rates of LRR were both 27%. Pretreatment factors that positively correlated with LRR were increasing T stage (P < .0001) and increasing combined clinical stage (P < .0001). Pathologic and treatment factors that positively correlated with LRR were size of the residual primary tumor (P = .0048), increasing number of involved lymph nodes (P < .0001), and no use of tamoxifen (P = .0013). The LRR rate for the 18 patients with a pathologic complete response of both the primary tumor and lymph nodes (pCR) was 19% (95% confidence interval, 6% to 48%). In a forward stepwise Cox logistic regression analysis, clinical stage IIIB or greater (hazard ratio of 4.5, P < .001), pathologic involvement of four or more lymph nodes (hazard ratio of 2.7, P = .008), and no use of tamoxifen (hazard ratio of 3.9, P = .027) independently predicted for LRR. CONCLUSION: Advanced disease at presentation and positive lymph nodes after chemotherapy predict for clinically significant rates of LRR. Achievement of pCR does not preclude the need for postmastectomy radiation if warranted by the pretreatment stage of the disease.

130 Background: Based on the JCOG 9907 trial results, neoadjuvant chemotherapy with cisplatin (CDDP) plus 5-fluorouracil (5-FU) is considered a standard treatment for stage II/III esophageal squamous cell carcinoma (ESCC) in Japan. However, patient survival remains unsatisfactory. We conducted a feasibility study of neoadjuvant chemoradiotherapy (NeoCRT) with CDDP plus 5-FU and elective nodal irradiation for stage II/III ESCC. Methods: Eligibility criteria included clinical stage II/III (UICC 6th, non-T4) ESCC, PS 0-1, and age 20–75 years. Chemotherapy consisted of 2 courses of 5-FU infusion (1000 mg/m2, days 1–4) and a 2-h CDDP infusion (75 mg/m2, day 1), with a 4-week interval. Radiotherapy was concurrently administered to a total 41.4 Gy in 23 fractions for primary tumor, metastatic lymph nodes and regional lymph nodes. After completion of CRT, transthoracic esophagectomy with extensive lymphadenectomy (>D2) was performed. The primary endpoint was the completion rate of NeoCRT and R0 resection. Results: From July 2010 to June 2011, 33 patients were enrolled, including 2 ineligibles. In 31 eligible patients, the median age was 63 years (range, 40–73); male/female: 28/3; PS0/1: 19/12; cStage IIA/IIB/III: 2/10/19. During CRT, the most common grade 3 or 4 toxicities were leukopenia (65%), neutropenia (65%), anemia (13%), thrombocytopenia (13%), febrile neutropenia (13%), anorexia (16%), esophagitis (16%), and hyponatremia (16%). In total, 31 patients (100%) underwent CRT and 25 (81%) underwent surgery; 1 patient (3%) did not undergo surgery due to disease progression, and the other 5 patients (16%) are scheduled for surgery. Among patients who underwent surgery, there was 1 treatment-related death, and the incidence of operative morbidity was similar to that in previous studies. According to RECIST, the overall response rate was 63% after CRT completion. Pathological complete response was achieved in 11 patients (44%) who underwent esophagectomy. Conclusions: NeoCRT was well tolerated and appears to be highly promising. The randomized controlled trial compared with neoadjuvant chemotherapy is needed and will be started.
