Definitive Chemoradiotherapy

Abstract Purpose The present study aimed to evaluate the long-term results of definitive chemoradiotherapy (CRT) for unresectable locally advanced esophageal squamous cell carcinoma (LA-ESCC). Materials and methods We analyzed eighty patients with unresectable LA-ESCC, who underwent definitive CRT between 2001 and 2014. The 5-year overall survival (OS), cause-specific survival (CSS), and progression-free survival (PFS) rates were calculated, and we investigated the prognostic factors and adverse events. Results The median age was 66 years (range, 41–83 years). Histologically, all patients had squamous cell carcinoma. The most common tumor site was the middle thoracic esophagus in 43 (54%) patients. According to the eighth edition of the Union for International Cancer Control TNM classification, sixty-six patients (83%) had T4 disease, 59 (74%) had regional lymph node (LN) metastases, and 35 (44%) had distant LN metastases beyond the regional LN (M1 LYM) disease. Forty-five (56%) and 35 (44%) patients belong to clinical stages IVA and IVB, respectively. The median follow-up period for survivors was 86 months. The 5-year OS, CSS, and PFS rates were 20.2%, 25.7%, and 18.4%, respectively. On univariate analysis, only the performance status score was significantly associated with better overall survival (p = 0.026). Grade 3 or higher late adverse events were observed in 12 (15%) patients, and these included cardiopulmonary adverse events in 6 (8%) patients. Treatment-related death occurred in 3 (4%) patients. Conclusion We showed the long-term results of definitive CRT for unresectable LA-ESCC. The survivals are still poor and new treatment strategies need to be developed.

4042 Background: The optimal use of the metabolic tumor response measured by 18fluorodeoxyglucose positron emission tomography (FDG-PET) in the treatment of esophageal cancer is currently unknown. We launched a phase II clinical trial to evaluate the early metabolic response to one-cycle chemotherapy in locally advanced esophageal squamous cell carcinoma (ESCC) patients, who subsequently received neoadjuvant chemoradiation (neo-CRT) followed by surgery. Methods: ESCC patients with stage T3 or N1M0 or M1a (AJCC, 6th edition) were enrolled to receive one-cycle chemotherapy, day 1 and 8 doses of paclitaxel, cisplatin, and 24-hour infusional 5-fluorouracil and leucovorin, followed by paclitaxel/cisplatin- based 40Gy neo-CRT and surgery. FDG-PET was performed at baseline and day 14 of the one-cycle chemotherapy. The primary endpoint is pathological complete response (pCR) to neo-CRT. We hypothesized that early PET responders, defined as > 35% reduction of maximum standardized uptake value (SUVmax) from the baseline, would significantly improve pCR. Results: Between Feb 2008 and Mar 2012, 66 patients (M: F = 61: 5) were enrolled. Their clinical stages were: II or III, 56; IVA, 10. Forty seven received surgery. The pCR rate per surgical population was 34.0%. The median progression-free survival (PFS) and overall survival (OS) for the whole study group was 16 months (95% CI 9-27) and 22 months (95% CI 16-40), respectively. A total of53 patients were evaluable for PET response. The early PET response was not associated with high pCR rate or better survivals. However, in an exploratory analysis, the post-chemotherapy SUVmax was an independent prognostic factor for pCR, PFS and OS. A predictive model for pCR composed of weight loss and the post-chemotherapy SUVmaxwas established with an AUC of 0.84. Conclusions: Our study failed to validate the predictive value of predefined early PET response to one-cycle chemotherapy for pCR to neo-CRT in locally advanced ESCC patients. However, the FDG-PET SUVmax after one-cycle chemotherapy may have prognostic and predictive significance, and may be explored in further studies. Clinical trial information: NCT01034332.
