Faculty Opinions recommendation of Biopsy proportion of tumour predicts pathological tumour response and benefit from chemotherapy in resectable oesophageal carcinoma: results from the UK MRC OE02 trial.

Abstract Background Neoadjuvant systemic therapy (NST) is increasingly used in the treatment of breast cancer, yet it is clear that there is significant geographical variation in its use in the UK. This study aimed to examine stated practice across UK breast units, in terms of indications for use, radiological monitoring, pathological reporting of treatment response, and post-treatment surgical management. Methods Multidisciplinary teams (MDTs) from all UK breast units were invited to participate in the NeST study. A detailed questionnaire assessing current stated practice was distributed to all participating units in December 2017 and data collated securely usingREDCap. Descriptive statistics were calculated for each questionnaire item. Results Thirty-nine MDTs from a diverse range of hospitals responded. All MDTs routinely offered neoadjuvant chemotherapy (NACT) to a median of 10% (range 5–60%) of patients. Neoadjuvant endocrine therapy (NET) was offered to a median of 4% (range 0–25%) of patients by 66% of MDTs. The principal indication given for use of neoadjuvant therapy was for surgical downstaging. There was no consensus on methods of radiological monitoring of response, and a wide variety of pathological reporting systems were used to assess tumour response. Twenty-five percent of centres reported resecting the original tumour footprint, irrespective of clinical/radiological response. Radiologically negative axillae at diagnosis routinely had post-NACT or post-NET sentinel lymph node biopsy (SLNB) in 73.0 and 84% of centres respectively, whereas 16% performed SLNB pre-NACT. Positive axillae at diagnosis would receive axillary node clearance at 60% of centres, regardless of response to NACT. Discussion There is wide variation in the stated use of neoadjuvant systemic therapy across the UK, with general low usage of NET. Surgical downstaging remains the most common indication of the use of NAC, although not all centres leverage the benefits of NAC for de-escalating surgery to the breast and/or axilla. There is a need for agreed multidisciplinary guidance for optimising selection and management of patients for NST. These findings will be corroborated in phase II of the NeST study which is a national collaborative prospective audit of NST utilisation and clinical outcomes.

14011 Background: The MRC OE02 study demonstrated pre-operative chemotherapy in patients with potentially operable oesophageal cancer improved survival. Pre-operative chemotherapy has been widely adopted in the UK. At our institution for the past 5 years patients with operable oesophageal cancer have routinely been given pre-operative chemotherapy with 3 cycles of Epirubicin, Cisplatin and Protracted Venous Infusion (PVI) 5FU (ECF). Recently, PVI 5FU has been replaced by Capecitabine (ECX). Methods: From March 2000 to October 2005, patients with operable oesophageal carcinoma have received 3 cycles of ECF or ECX (Epirubicin 50mg/m2, Cisplatin 60mg/m2, and PVI 5FU 200mg/m2 per day or Capecitabine 625mg/m2 po bd for 21 days). Disease response was assessed by CT scan and surgery was performed 4–6 weeks after completion of chemotherapy. Results: 59 patients received neo-adjuvant chemotherapy (48 received ECF, 11 ECX). Median age was 64. Fifty-three patients (89.8%) completed the planned 3 cycles of chemotherapy. WHO grade 3 or 4 toxicity occurred in 7 patients (11.8%): 6 haematological with 1 toxic death among them (1.7%) and 1 mucositis. Forty-four of 49 patients (89.7%) with dysphagia reported improvement of their symptoms as a result of chemotherapy. Fifty-two patients (88.1%) proceeded to surgery of which 47 (90.3%) underwent complete tumour resection, 4 patients (7.7%) were found to have inoperable/metastatic disease and 1 patient had incomplete excision (1.9%). Median follow-up was 26.8 months with overall median survival of 36.2 months and a 2-year survival of 63.2%. Thirty-four (57.6%) patients remain alive to date of which, 30 are disease-free and 4 are alive with recurrent disease. Conclusions: These encouraging results demonstrate that 3 cycles of preoperative ECF/ECX chemotherapy in patients with operable oesophageal cancer allow surgery to be safely performed in the vast majority of patients and our 2-year survival compare favourably with previously reported series. These results suggest that 3 cycles of pre-operative treatment with ECF/ECX chemotherapy may improve survival in this group of patients and is worthy of further research.
