“…were consistent with what had previously been reported for FLOT in younger patient collectives [6]. However, compared with FLO, a significant increase in overall grade 3 and 4 toxicity was seen (FLOT, 82 %; FLO, 39 %; P \ 0.001), especially considering neutropenia, leukopenia, diarrhea, and nausea [7].…”

Background Treatment of patients with advanced or metastatic esophagogastric adenocarcinoma should not only prolong life but also provide relief of symptoms and improve quality of life (QOL). Esophagogastric adenocarcinoma mainly occurs in elderly patients, but they are underrepresented in most clinical trials and often do not receive effective combination chemotherapy, most probably for fear of intolerance. Using validated instruments, we prospectively assessed QOL within the randomized FLOT65? phase II trial. Methods Within the FLOT65? trial, a total of 143 patients aged C65 years were randomly allocated to receive biweekly oxaliplatin plus 5-fluorouracil (5-FU) continuous infusion and folinic acid (FLO) or the same regimen in combination with docetaxel 50 mg/m 2 (FLOT).The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) and the gastric module STO22 were administered every 8 weeks until progression. Time to definitive deterioration of QOL parameters was analyzed and compared within the treatment arms. Results The median age of patients was 70 years. Patients receiving FLOT exhibited higher response rates and had improved disease-free and progression-free survival (PFS). The proportions of patients with evaluable baseline EORTC QLQ-C30 and STO22 questionnaires were balanced (83 % in FLOT and 89 % in FLO). Considering evaluable patients with assessable questionnaires (n = 123), neither functioning nor symptom parameters differed significantly in favor of one of the two treatment groups. Particularly, there was no significant difference regarding time to definitive deterioration of global health status/quality of life from baseline (primary endpoint). Notably, patients receiving FLO or FLOT as palliative treatment (n = 98) achieved comparable QOL results. Conclusions Although toxicity was higher in patients receiving FLOT, no negative impact of the addition of docetaxel on QOL parameters could be demonstrated. Thus, elderly patients in need of intensified chemotherapy may receive FLOT without compromising patient-reported outcome parameters.

“…Our results are supported by other studies that have tested the combination of 5-FU, docetaxel and oxaliplatin, and by a large phase II trial in which Al-Batran et al [20] used a regimen similar to TEF, but using 5-FU in a 24-h continuous infusion at the dose of 2600 mg/m 2 (FLOT). The results were excellent with a response rate of 57.7 %, a progression-free survival of 5.2 months and an OS of 11.1 months and are confirmed by the results reported here with the TEF regimen.…”

Biweekly docetaxel, fluorouracil, leucovorin, oxaliplatin (TEF) as first-line treatment for advanced gastric cancer and adenocarcinoma of the gastroesophageal junction: safety and efficacy in a multicenter cohort

Background Docetaxel-cisplatin-5-FU chemotherapy is superior to 5-FU-cisplatin in terms of response rate and survival in advanced gastric cancer (AGC), but is more toxic. Oxaliplatin is better tolerated than cisplatin, which it can effectively replace in this setting. We hypothesize that incorporating docetaxel into a simplified FOLFOX regimen should be a tolerable and effective option in first-line treatment of AGC. Methods Data were collected at six French centers from patients with metastatic or local AGC who received docetaxel, fluorouracil, leucovorin, or oxaliplatin (TEF) as first-line treatment. TEF was administered as follows: docetaxel (50 mg/m 2 ), oxaliplatin (85 mg/m 2 ), and leucovorin (40 mg/m 2 ) on day 1, and 5-FU continuous infusion for 48 h (2400 mg/m 2 ) every 2 weeks.Results Forty-one patients were enrolled. Performance status was grade 0 and 1 in respectively 27 and 58 % of patients; 17 patients had adenocarcinoma of the gastroesophageal junction; 37 patients had metastatic disease, 22 had a poorly differentiated or diffuse type. Objective response rate was 66 %, with a complete response in two patients (5 %). Median progression-free survival and overall survival were respectively 6.3 and 12.1 months. Tolerability was acceptable with no treatment-related deaths. The most frequent grade 3-4 toxicities were neutropenia (30 %) and neuropathy (12.5 %). Curative intent surgery after response to TEF was performed in seven patients (17 %). Conclusion TEF is an effective first-line treatment with an acceptable toxicity profile for patients with AGC. It may allow curative resection in initially unresectable patients. TEF should now be evaluated in prospective randomized trials.

Background Neoadjuvant chemotherapy is an accepted standard of care for locally advanced esophagogastric cancer. As only a subgroup benefits, a response-based tailored treatment would be of interest. The aim of our study was the evaluation of the prognostic and predictive value of clinical response in esophagogastric adenocarcinomas. Methods Clinical response based on a combination of endoscopy and computed tomography (CT) scan was evaluated retrospectively within a prospective database in center A and then transferred to center B. A total of 686/740 (A) and 184/210 (B) patients, staged cT3/4, cN0/1 underwent neoadjuvant chemotherapy and were then restaged by endoscopy and CT before undergoing tumor resection. Of 184 patients, 118 (B) additionally had an interim response assessment 4-6 weeks after the start of chemotherapy. Results In A, 479 patients (70 %) were defined as clinical nonresponders, 207 (30 %) as responders. Median survival was 38 months (nonresponders: 27 months, responders: 108 months, log-rank, p \ 0.001). Clinical and histopathological response correlated significantly (p \ 0.001). In multivariate analysis, clinical response was an independent prognostic factor (HR for death 1.4, 95 %CI 1.0-1.8, p = 0.032). In B, 140 patients (76 %) were nonresponders and 44 (24 %) responded. Median survival was 33 months, (nonresponders: 27 months, responders: not reached, Electronic supplementary material The online version of this article
