S14 Phase II Trial A histological grade 3 was the only clinicopathological factor independently associated with pCR (p = 0.004)

Tumors which did not express FGFR1 protein on pretreatment biopsies were more resistant to chemoradiotherapy than those with FGFR1 expression

The FGFR1 tumoral expression was independent from the proliferative markers (histological grade and mitotic index), meaning that this gives us an additional information on the tumoral phenotype.

Could  RT  replace  surgery  ader  NA  CT  for  early  breast  cancers?  

Neoadjuvant therapy, compared with adjuvant therapy, was associated with a statistically significant increased risk of loco- regional recurrence when radiotherapy without surgery was adopted

Year of diagnosis

RT Surgery

165 pts with cCR after 4 cycles of NA CT: 100 RT, 65 surgery (12 mastectomies)

Larger tumours treated with RT Trend towards younger with RT

FDG PET capability to predict pCR of NA CT was, after 2 courses, associated with a sensitivity, specificity, and negative predictive value of 89%, 95%, and 85%

Conclusion

Page 35: Marc Bollet :  Role of radiation oncologist in neoadjuvant breast cancer treatment

Conclusions

. Is there a real contra-indication to a breast RT?

. Could pre-operative RT be called for?

Meeting early with the radiation oncologist could be of value in some cases

Different CT regimen are tested concurrently to RT to ameliorate therapeutic ratio (Taxanes, Vinorelbine…)

Interesting Neoadjuvant results, and non randomised data in rescue

Optimisation of radiotherapy techniques, and prediction of response to chemoradiotherapy are warranted

Chemoradiotherapy is an option for Inoperable breast Cancers under Neoadjuvant chemotherapy (≈2%), and Inflammatory breast cancers (> 5%)

Patients should be refered for surgery whenever possible in a M0 setting

Pourquoi associer RT et CT ?

1. Pas de retard entre initiation de la RT et de la CT 2. Potentialisation de la RT et augmentation du CLR 3. Diminution du temps de traitement global

NSABP : RT-CT conco = 0,5% RLR/an CT puis RT >1% RLR/an

Pourquoi ne pas associer RT et CT ?

1.  RT = risque d’impacter le capital médullaire et la dose intensité de la CT

2. Les CT (ex anthracycline) ne sont pas toutes compatibles de façon concomitante avec la RT 3. Augmentation des toxicités

6 cycles of (AC60, FAC50; FEC75) or CMF

After mastectomy or BCT, the adjuvant treatment based on RT and concurrent anthracycline CHT (vs CMF) reduced breast cancer relapse rate, and significantly improved LRFS, EFS and OS in the patients receiving more than 1 cycle of concurrent CT. There were more hematologic and non hematologic toxicities in the anthracycline group

PURPOSE: This study was done to evaluate the toxicity related to concurrent radiotherapy and anthracycline (AC)-based chemotherapy in the adjuvant treatment of early breast cancer and to investigate the impact of treatment interruptions and the feasibility of this uncommon therapeutic approach .MATERIALS AND METHODS: From September 2002 to December 2007, 60 patients were treated at our Centre. The mean age at presentation was 48.5 (range 38-64) years. All patients underwent conservative surgery, and radiotherapy to the entire breast (mean dose 50 Gy; range 46-52 Gy). AC-based regimens consisted of four cycles of AC (doxorubicin plus cyclophosphamide) or four cycles of epirubicin (EPI) followed by four courses of cyclophosphamide, methotrexate and 5-fluorouracil (CMF). RESULTS: Concomitant treatment caused acute skin G3 toxicity in 8.9% of patients and one case of G4 toxicity (1.7%). Concerning cardiac assessment, six of the 56 evaluable patients (10.7%) developed an asymptomatic decline of left ventricular ejection fraction >10% and <20% of the baseline value. Radiotherapy was temporarily stopped in 21.3% and chemotherapy in 57.1% of patients. CONCLUSIONS: In our experience, concomitant chemotherapy did not emerge as a significant factor in radiotherapy interruption. Moreover, no severe cardiac events were recorded.

A feasibility study of neo-adjuvant low-dose fractionated radiotherapy with two different concurrent anthracycline-docetaxel schedules in stage IIA/B-IIIA breast cancer. Nardone L et al. Tumori. 2012 Jan-Feb;98(1):79-85.

AIMS AND BACKGROUND: The aim of the study was to evaluate the feasibility of neoadjuvant low-dose fractionated radiotherapy, in combination with two anthracycline-docetaxel regimens, in breast cancer treatment. MATERIALS AND METHODS: Women with stage IIA/B-IIIA breast cancer were assigned to receive the treatment of low-dose fractionated radiotherapy (0.4 Gy/per fraction, 2 fractions per day, for 2 days, every 21 days for 8-6 cycles) with concomitant neoadjuvant chemotherapy with non-pegylated liposomal doxorubicin and docetaxel. Two chemotherapy schedules were planned to be combined with low-dose fractionated radiotherapy. The first schedule consisted of four cycles of non-pegylated liposomal doxorubicin sequentially followed by four cycles of docetaxel, and the second schedule consisted of six cycles of non-pegylated liposomal doxorubicin plus concomitant docetaxel. Acute toxicity was evaluated according to the Radiation Therapy Oncology Group score system. Pathological response was evaluated by the Mandard score and expressed as tumor regression grade. RESULTS: Between March 2008 and February 2009, 10 patients underwent low-dose fractionated radiotherapy and concomitant chemotherapy. No grade 3-4 breast toxicity was observed. Five patients had a clinical complete response. Seven patients underwent conservative surgery. Overall, tumor regression grade 1 (absence of residual cancer) was achieved in one patient (10%) and grade 2 (residual isolated cells scattered through the fibrosis) in 4 patients (40%). The pathologic major response rate (tumor regression grade 1 + 2) was 20% in patients receiving low-dose fractionated radiotherapy and sequential non-pegylated liposomal doxorubicin and docetaxel and 80% in the group receiving low-dose fractionated radiotherapy and concurrent non-pegylated liposomal doxorubicin and docetaxel treatment. CONCLUSIONS: Concomitant low-dose fractionated radiotherapy combined with anthracycline and docetaxel is feasible. The toxicity profile of radio-chemotherapy was similar to that of chemotherapy alone: there was no acute skin or cardiac toxicity. The concurrent application of liposomal doxorubicin and docetaxel with low-dose fractionated radiation led to higher histological response rates compared to the sequential application of the same two drugs.
