A Surrogate Endpoint for Overall Survival in Locally Advanced and Resectable Esophageal Squamous Cell Carcinoma: A Reanalysis of Data From the NEOCRTEC5010 Trial. Int J Radiat Oncol Biol Phys 2023; 117:809-820. [PMID: 37210047 DOI: 10.1016/j.ijrobp.2023.05.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 04/27/2023] [Accepted: 05/13/2023] [Indexed: 05/22/2023]
Abstract
PURPOSE This study aimed to investigate disease-free survival (DFS) as a surrogate endpoint for overall survival (OS) in patients with locally advanced and resectable esophageal squamous cell carcinoma. METHODS AND MATERIALS We re-analyzed patient data from the NEOCRTEC5010 randomized controlled trial (N = 451 patients) to compare their OS with that of an age- and sex-matched cohort from the general population of China. We used expected survival and the standardized mortality ratio, respectively, in our analysis of data collected from a neoadjuvant chemoradiation therapy (NCRT) plus surgery group and a surgery-only group. Published data from 6 randomized controlled trials and 20 retrospective studies were used to examine the correlation between DFS and OS at the trial level. RESULTS The annual hazard rate of disease progression decreased to 4.9% and 8.1% within 3 years in the NCRT and surgery groups, respectively. Patients who were disease-free at 36 months had a 5-year OS of 93.9% (95% CI, 89.7%-98.4%) in the NCRT group with a standardized mortality ratio of 1.1 (95% CI, 0.7-1.8; P = .5639). In contrast, the 5-year OS was only 12.9% (95% CI, 7.3%-22.6%) for patients in the NCRT group who exhibited disease progression within 36 months. At the trial level, DFS and OS were correlated with treatment effect (R2 = 0.605). CONCLUSIONS Disease-free status at 36 months is a valid surrogate endpoint for 5-year OS in patients with locally advanced and resectable esophageal squamous cell carcinoma. Patients who were disease-free at 36 months showed a favorable OS, which was indistinguishable from that of the age- and sex-matched comparison group from the general population; otherwise, their 5-year OS was extremely poor.

Radiation Dose-Effect Relation in Patients with Esophageal Squamous Cell Carcinoma: A National Cancer Center Data and Literature-Based Analysis. JOURNAL OF ONCOLOGY 2022; 2022:2438270. [PMID: 36317125 PMCID: PMC9617729 DOI: 10.1155/2022/2438270] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/14/2022] [Accepted: 10/03/2022] [Indexed: 11/28/2022]
Abstract
Introduction Despite receiving definitive chemoradiotherapy (dCRT) with radiation dose (RTD) of 50.4 Gy, survival of esophageal carcinoma was dismal. The effect of RTD in cancer control and radiotoxicity, and the extent to which local-regional control (LRC) influenced survival remain vague. This study aimed at evaluating RTD-effect relationship in esophageal squamous cell carcinoma (ESCC). Methods 1440 dRT/CRT-treated ESCC patients were enrolled. Restricted cubic spline regression model was applied to reveal nonlinear relationship between RTD and survival/radiotoxicity. Linear regression analysis (LRA) was performed to evaluate correlations between LRC and overall survival (OS) or progression-free survival (PFS). Results For 1440 dRT/CRT-treated ESCC patients, with RTD escalating, hazard ratios (HRs) of OS, PFS, LRC declined until RTD exceeded 60 Gy, then increased. HR of treatment-related mortality was stable until RTD exceeded 60 Gy, then increased. HR of LRC was lower for majority of patients treated with RTD≥60 Gy, except for those with KPS<80, T1-2 lesion, or without lymph node metastasis. LRA revealed strong correlations between LRC and OS/PFS. 45.5% and 44.9% of OS and PFS improvements were owing to improved LRC. Conclusions RTD of 60 Gy was well tolerated, with favorable survival resulted of LRC improvement in local-advanced ESCC. Further stratification analyses based on radiation sensitivity will be helpful to determine potential beneficiaries of RTD escalation.

Abstract
Purpose To determine the efficacy and toxicity of two standard chemotherapy regimens used concurrent with radiation for the treatment of esophageal cancer: cisplatin/5-fluorouracil (5-FU) and carboplatin/paclitaxel. Materials and methods We prospectively reviewed records of 364 patients with histologically confirmed stage I to IVA esophageal cancer receiving chemoradiotherapy (CRT) with or without resection. All patients received surgical evaluation and imaging at presentation as well as following completion of their course of CRT. Treatment and prognostic variables were compared across the two chemotherapy regimens. Results We identified 261 patients treated with concurrent carboplatin/paclitaxel (n = 133) or cisplatin/5-FU (n = 128). Weight loss during CRT was lower in patients receiving carboplatin/paclitaxel (median: 7.0 pounds; 4.1% body weight) vs. cisplatin/5-FU (median: 11.0 pounds; 6.5% body weight) (p < 0.01). In 117 patients receiving trimodality therapy, post-operative death rates within one month of resection were similar. Pathologic complete response was better with carboplatin/paclitaxel vs. cisplatin/5-FU, 29.6% vs. 21.8% (p = 0.03), respectively. In the multivariable analysis, there was no association between chemotherapy regimen and overall survival (OS) or progression-free survival (PFS), though there was a trend toward improved OS with carboplatin/paclitaxel with a HR = 0.75 (p = 0.08). Further analysis revealed that trimodality therapy and stage were predictors for improved OS and PFS while female gender and grade predicted for improved PFS. Conclusions Carboplatin/paclitaxel was associated with decreased weight loss and improved pathologic response for trimodality patients when compared to cisplatin/5-FU. We observed no differences in OS, PFS, or post-operative death by chemotherapy regimen for both the entire cohort and trimodality patients.

A multicenter prospective phase III clinical randomized study of simultaneous integrated boost intensity-modulated radiotherapy with or without concurrent chemotherapy in patients with esophageal cancer: 3JECROG P-02 study protocol. BMC Cancer 2020; 20:901. [PMID: 32962674 PMCID: PMC7510301 DOI: 10.1186/s12885-020-07387-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Accepted: 09/08/2020] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Since the development of three-dimensional conformal radiotherapy and intensity-modulated radiotherapy (IMRT), no prospective study has investigated whether concurrent chemoradiotherapy (SIB-IMRT with 60 Gy) remains superior to radiotherapy (SIB-IMRT) alone for unresectable esophageal cancer (EC). Furthermore, the optimal therapeutic regimen for patients who cannot tolerate concurrent chemoradiotherapy is unclear. We recently completed a phase I/II radiation dose-escalation trial using simultaneous integrated boost (SIB), elective nodal irradiation, and concurrent chemotherapy for unresectable EC. We now intend to conduct a prospective, phase III, randomized study of SIB-IMRT with or without concurrent chemotherapy. We aim to find a safe, practical, and effective therapeutic regimen to replace the conventional segmentation (1.8-2.0 Gy) treatment mode (radiotherapy ± chemotherapy) for unresectable EC. METHODS This two-arm, open, randomized, multicenter, phase III trial will recruit esophageal squamous cell carcinoma patients (stage IIA-IVB [UICC 2002]; IVB only with metastasis to the supraclavicular or celiac lymph nodes). In all, 164 patients will be randomized using a 1:1 allocation ratio, and stratified by study site and disease stage, especially the extent of lymph node metastasis. Patients in the SIB arm will receive definitive SIB radiotherapy (95% planning target volume/planning gross tumor volume, 50.4 Gy/59.92 Gy/28 f, equivalent dose in 2-Gy fractions = 60.62 Gy). Patients in the SIB + concurrent chemotherapy arm will receive definitive SIB radiotherapy with weekly paclitaxel and a platinum-based drug (5-6 weeks). Four cycles of consolidated chemoradiotherapy will also be recommended. The primary objective is to compare the 1-year, 2-year, and 3-year overall survival of the SIB + chemotherapy group and SIB groups. Secondary objectives include progression-free survival, local recurrence-free rate, completion rate, and adverse events. Detailed radiotherapy protocol and quality-assurance procedures have been incorporated into this trial. DISCUSSION In unresectable, locally advanced EC, a safe and effective total radiotherapy dose and reasonable segmentation doses are required for the clinical application of SIB-IMRT + two-drug chemotherapy. Whether this protocol will replace the standard treatment regimen will be prospectively investigated. The effects of SIB-IMRT in patients with poor physical condition who cannot tolerate definitive chemoradiotherapy will also be investigated.

Abstract
AIM To identify the serum metabolomics signature that is correlated with the chemoradiosensitivity of esophageal squamous cell carcinoma (ESCC). MATERIALS & METHODS Untargeted and targeted metabolomics analysis of serum samples from 26 ESCC patients, which were collected before the neoadjuvant chemoradiotherapy, was performed. RESULTS On receiving the results of untargeted metabolomics analysis, we performed the targeted metabolomics analysis of the six metabolites (arabitol, betaine, glycine, L-serine, L-arginine and L-aspartate). The serum levels of the four metabolites (arabitol, glycine, L-serine and L-arginine) were significantly lower in the patients who achieved pathological complete response with neoadjuvant chemoradiotherapy compared with the patients who did not achieve pathological complete response (p = 0.0086, 0.0345, 0.0106 and 0.0373, respectively). CONCLUSION The serum levels of metabolites might be useful for predicting the chemoradiosensitivity of ESCC patients.

Abstract
BACKGROUND AND AIM Preoperative chemoradiotherapy (CRT) followed by esophagectomy is a well-known treatment modality for patients with locally advanced esophageal cancer (EC). This study developed an algorithm to predict pathological complete response (CR) in these patients using post-CRT endoscopic category with biopsy and validated the proposed algorithm. METHODS A retrospective review of 141 consecutive patients who completed preoperative CRT and underwent surgical resection for locally advanced EC was performed. The post-CRT endoscopic findings of each patient were stratified into five categories. RESULTS The distribution of post-CRT endoscopic categories was significantly different between the pathological CR and non-pathological CR groups (P < 0.001). About 76.8% (73/95) of patients in category 0, 1, or 2 achieved pathological CR. In contrast, 91.3% (42/46) of endoscopic categories 3 and 4 patients did not achieve pathological CR. Sensitivity of post-CRT biopsy was 11.1%. Therefore, an algorithm combining biopsy results and dichotomized post-CRT endoscopic category (category 0, 1, or 2 vs category 3 or 4) was developed. The sensitivity, specificity, and accuracy in predicting pathological CR by the proposed algorithm were 64.8%, 95.9%, and 82.8%, respectively. In the multivariate analysis, the proposed algorithm remained a significant negative factor of survival (P < 0.001). CONCLUSIONS Algorithm using post-CRT endoscopic category with biopsy may help identify locally advanced EC patients who achieved pathological CR after preoperative CRT. Modalities to accurately detect subepithelial remnant EC may further aid in predicting pathological CR.

Abstract
BACKGROUND Older patients with esophageal cancer are at high risk of adverse health outcomes, but the association of geriatric assessment with adverse health outcomes in these patients has not been systematically evaluated. The aim of this systematic review was to study the association of functional and cognitive impairment, social environment and frailty with adverse health outcomes in patients diagnosed with esophageal cancer. METHODS We searched Pubmed, Embase, Web of Science and Cochrane Library for original studies reporting on associations of functional or cognitive impairment, social environment and frailty with adverse outcomes (mortality, functional or cognitive decline, adverse events during treatment, prolonged length of hospitalization (LOS) and health related quality of life (HRQoL)) after follow-up in patients with esophageal cancer. RESULTS Of 1.391 identified citations, nineteen articles were included that reported on 53 associations. The median sample size of the included studies was 110 interquartile range (IQR 91-359). Geriatric conditions were prevalent: between 14 and 67% of the included participants were functionally impaired, around 42% had depressive symptoms and between 5 and 23% did not have a partner. In nineteen of 53 (36%) associations functional or cognitive impairment or frailty were significant associated with adverse health outcomes, but the studies were small. In four out of six (67%) associations with the largest sample size (n ≥ 359), functional impairment or social environment were significant associated with adverse health outcomes. CONCLUSION Functional and cognitive impairment, depression and social isolation are prevalent in patients with esophageal cancer, and associate with adverse health outcomes. Geriatric measurements may guide decision-making and customize treatments, but more large studies are needed to explore the clinical usability.

Xi M, Liao Z, Deng W, Komaki R, Ho L, Lin SH. Recursive Partitioning Analysis Identifies Pretreatment Risk Groups for the Utility of Induction Chemotherapy Before Definitive Chemoradiation Therapy in Esophageal Cancer. Int J Radiat Oncol Biol Phys 2017; 99:407-416. [PMID: 28871991 DOI: 10.1016/j.ijrobp.2017.05.050] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2017] [Revised: 04/26/2017] [Accepted: 05/30/2017] [Indexed: 01/14/2023]
Abstract
PURPOSE To assess the contribution of induction chemotherapy (IC) before definitive chemoradiation therapy (dCRT) in patients with esophageal cancer (EC) based on recursive partitioning analysis (RPA). METHODS AND MATERIALS A total of 496 eligible patients with EC staged by positron emission tomography (PET) who received dCRT from 1998 to 2015 were included, 162 (32.7%) of whom underwent IC before dCRT. RPA was used to risk-stratify patients on the basis of independent prognostic factors to predict progression-free survival (PFS). Outcomes were compared between treatment groups. RESULTS The median follow-up time was 49.1 months (range, 7.0-155.9 months) for survivors. Compared with the non-IC group, the IC group had a comparable 5-year PFS rate (21.0% vs 23.4%; P=.726) in the whole cohort. Multivariate analysis identified age, performance status, primary tumor length, baseline PET maximum standard uptake value (SUVmax), and maximum lymph node diameter as independent prognostic factors for PFS. RPA segregated patients into 3 prognostic groups: low-risk group (PET SUVmax <9.7 and tumor length ≤5 cm), intermediate-risk group (PET SUVmax ≥9.7 and age ≥67), and high-risk group (PET SUVmax <9.7 and tumor length >5 cm, or PET SUVmax ≥9.7 and age <67). Significant improvements in PFS (P=.006) and locoregional failure-free survival (P=.028) in the IC group in comparison with the non-IC group were observed in high-risk patients, whereas no differences in survival were found between the 2 treatment groups in low-risk or intermediate-risk patients. After propensity score matching, the high-risk group still demonstrated a significantly improved PFS with IC (P=.009). CONCLUSIONS The RPA prognostic grouping provides a useful method of selecting high-risk EC patients who may benefit from IC before receiving dCRT. Prospective validation is warranted.

Abstract
BACKGROUND/AIMS Approximately 30% of esophageal cancer (EC) patients cannot complete endoscopic ultrasonography (EUS) due to malignant stricture (EUS non-traversability). This study examines clinical implications of EUS non-traversability in patients with advanced locoregional squamous EC receiving preoperative chemoradiotherapy (CRT) followed by esophagectomy. METHODS We retrieved data on 89 consecutive patients with advanced locoregional squamous EC (stage II or III). Relevant clinical and tumor-specific parameters were reviewed retrospectively. Significant factors affecting survival was determined by Cox regression analysis. RESULTS EUS non-traversable EC was observed in 26 of 89 patients (29.2%). Median serum albumin level (3.6 g/dL vs. 3.9 g/dL, p = 0.028), tumor length (6.0 cm vs. 4.0 cm, p = 0.002), and percentage of clinical stage III disease (65.4% vs. 38.1%, p = 0.019) were significantly different between the patients with EUS non-traversable and traversable EC, respectively. Patients with EUS non-traversable EC demonstrated a significantly lower 5-year overall survival than patients with EUS traversable EC (30.8% vs. 49.3%, p = 0.023). In multivariate analysis, weight loss ≥ 10% (p = 0.033), EUS non-traversability (p = 0.003), non-response to preoperative CRT (p = 0.002), and incompletion of esophagectomy (p = 0.002) were significant negative factors of survival. CONCLUSIONS EUS non-traversability has significant negative prognostic implications in patients with advanced locoregional squamous EC receiving preoperative CRT followed by esophagectomy.

Postchemoradiotherapy Pathologic Stage Classified by the American Joint Committee on the Cancer Staging System Predicts Prognosis of Patients with Locally Advanced Esophageal Squamous Cell Carcinoma. J Thorac Oncol 2016; 10:1481-9.

Abstract
INTRODUCTION To determine whether the postchemoradiotherapy (post-CRT) pathologic stage predicts the outcomes of patients with locally advanced esophageal squamous cell carcinoma (ESCC) undergoing preoperative CRT followed by surgery. METHODS From three phase II trials of preoperative CRT for locally advanced ESCC, 140 patients were included. Preoperative CRT comprised twice weekly paclitaxel and cisplatin-based regimens and 40-Gy radiotherapy in 20 fractions. The post-CRT pathologic stage was classified according to the American Joint Committee on Cancer, 7th edition staging system. The prognostic effects of clinicopathologic factors were analyzed using Cox regression. RESULTS With a median follow-up of 61.9 months, the median progression-free survival (PFS) and overall survival (OS) of the entire cohort were 24.5 and 30.9 months, respectively. The post-CRT pathologic stage was 0 in 34.5%, I in 12.9%, II in 29.3%, III in 13.6%, and ypT0N1-2 in 6.4% of the patients. The median PFS was 47.2, 25.9, 16.0, 9.4, and 15.1 months, and the median OS was 57.4, 34.1, 26.2, 14.1, and 17.6 months for patients with post-CRT pathologic stage 0, I, II, III, and ypT0N1-2, respectively. In multivariate analysis, performance status (p < 0.001), tumor location (p = 0.016), and extranodal extension (p = 0.024) were independent prognostic factors for PFS, whereas performance status (p < 0.001) and post-CRT pathologic stage (p = 0.027) were independent prognostic factors for OS. CONCLUSIONS The post-CRT pathologic stage classified by American Joint Committee on Cancer, 7th edition staging system predicted the survival of locally advanced ESCC patients who underwent preoperative paclitaxel and cisplatin-based CRT followed by esophagectomy.

Synchronous second primary cancers in patients with squamous esophageal cancer: clinical features and survival outcome. Korean J Intern Med 2016; 31:253-9. [PMID: 26864297 PMCID: PMC4773710 DOI: 10.3904/kjim.2014.182] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2014] [Revised: 11/15/2014] [Accepted: 12/11/2014] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND/AIMS Unexpected diagnosis of synchronous second primary cancers (SPC) complicates physicians' decision-making because clinical details of squamous esophageal cancer (EC) patients with SPC have been limited. We evaluated clinical features and treatment outcomes of patients with synchronous SPC detected during the initial staging of squamous EC. METHODS We identified a total of 317 consecutive patients diagnosed with squamous EC. Relevant clinical and cancer-specific information were reviewed retrospectively. RESULTS EC patients with synchronous SPC were identified in 21 patients (6.6%). There were significant differences in median age (70 years vs. 63 years, p = 0.01), serum albumin level (3.3 g/dL vs. 3.9 g/dL, p < 0.01) and body mass index (20.4 kg/m(2) vs. 22.8 kg/m(2), p = 0.01) between EC patients with and without SPC. Head and neck, lung and gastric cancers accounted for 18.2%, 22.7%, and 18.2% of SPC, respectively. Positron emission tomography-computed tomography (PET-CT) detected four cases (18.2%) of SPC that were missed on CT. Management plans were altered in 13 of 21 patients (61.9%) with detected SPC. Curative esophagectomy was attempted in 28.6% of EC patients with SPC (vs. 59.1% of patients without SPC; p = 0.006). EC patients with SPC had significantly lower 5-year survival than patients without SPC (10.6% vs. 36.7%, p = 0.008). CONCLUSIONS Synchronous SPC were found in 6.6% of squamous EC patients, and PET-CT contributed substantially to the detection of synchronous SPC. EC patients with SPC had poor survival due to challenges of providing stage-appropriate treatment.

Abstract
BACKGROUND/AIM Little is known about the patterns of treatment failure following definitive chemoradiotherapy (CCRT), especially in esophageal squamous cell carcinoma (SCC). We evaluated definitive CCRT failure patterns and determined the predictive factors for treatment response in esophageal SCC. METHODS We evaluated 136 consecutive patients with esophageal SCC treated with definitive CCRT. We evaluated the factors associated with complete remission (CR) after CCRT and analyzed the pattern of treatment failure of recurred patients and incomplete remission patients. The failures were categorized as either within (locoregional failure) or outside the radiation field (out-field failure). RESULTS Fifty-seven patients achieved CR after CCRT. Consolidation chemotherapy was significantly associated with CR. Only 4 (7.0%) patients had CR after CCRT in patients with M1a node (Celiac or subclavian lymph nodes involvement by 6th AJCC). During follow-up, 74 patients (54.4%) experienced locoregional failure, 26 (19.1%) out-field failure, and 35 (25.7%) no failure. Esophageal obstruction prior to CCRT, residual tumor according to the first follow-up endoscopy, and poor follow-up computed tomography responses were significantly associated with locoregional failure. CONCLUSION Approximately 70% of treatment failures were local failures. Future therapeutic strategies need to focus on improving local control to increase treatment outcomes of CCRT.

Abstract
Purpose To evaluate treatment outcomes and determine prognostic factors in patients with esophageal cancer treated with esophagectomy after neoadjuvant chemoradiotherapy (NCRT). Materials and Methods We retrospectively evaluated 39 patients with esophageal cancer who underwent concurrent chemoradiotherapy followed by esophagectomy between 2002 and 2012. Initial clinical stages of patients were stage IB in 1 patient (2.6%), stage II in 5 patients (12.9%), and stage III in 33 patients (84.6%). Results The median age of all the patients was 62 years, and the median follow-up period was 17 months. The 3-year overall survival (OS) rate was 33.6% in all the patients. The 3-year locoregional recurrence-free survival (LRFS) rate was 33.7%. In multivariate analysis with covariates of age, the Eastern Cooperative Oncology Group performance status, hypertension, diabetes mellitus, tumor length, clinical response, clinical stage, pathological response, pathological stage, lymphovascular invasion, surgical type, and radiotherapy to surgery interval, only pathological stage was an independent significant prognostic factor affecting both OS and LRFS. The complications in postoperative day 90 were pneumonia in 9 patients, anastomotic site leakage in 3 patients, and anastomotic site stricture in 2 patients. Postoperative 30-day mortality rate was 10.3% (4/39); the cause of death among these 4 patients was respiratory failure in 3 patients and myocardial infarction in one patient. Conclusion Only pathological stage was an independent prognostic factor for both OS and LRFS in patients with esophageal cancer treated with esophagectomy after NCRT. We could confirm the significant role of NCRT in downstaging the initial tumor bulk and thus resulting in better survival of patients who gained earlier pathological stage after NCRT.

Abstract
BACKGROUND/AIMS We investigated the clinical outcomes according to the method of treatment in synchronous esophageal and gastric cancer. METHODS Synchronous esophageal squamous cell carcinoma and gastric adenocarcinoma were diagnosed in 79 patients between 1996 and 2010. We divided the patients into four groups according to treatment; Group 1 received surgical resection for both cancers or surgery for gastric cancer with chemoradiotherapy for esophageal cancer (n=27); Group 2 was treated by endoscopic resection with or without additional treatment (n=14); Group 3 received chemoradiotherapy only (n=18); and Group 4 received supportive care only (n=20). RESULTS The median survival times in groups 1 and 2 were 86 and 60 months, respectively. The recurrence rate and mortality were 23% and 48%, respectively, in group 1 and 21% and 4%, respectively, in group 2. The median survival time was 12 months in group 3 and 9 months in group 4. Multivariate analysis showed that age (p<0.001) and treatment group (p=0.019) were significantly associated with death. Compared with group 1, treatment in the intensive care unit (p=0.003), loss of body weight (p=0.042), and decrease in hemoglobin (p=0.033) were worse in group 1. CONCLUSIONS Endoscopic resection for synchronous esophageal and gastric cancer could be considered as a possible alternative to surgery for early-stage cancer.

Preoperative chemoradiation therapy in combination with panitumumab for patients with resectable esophageal cancer: the PACT study. Int J Radiat Oncol Biol Phys 2014; 90:190-6. [PMID: 25195993 DOI: 10.1016/j.ijrobp.2014.05.022] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2014] [Revised: 05/10/2014] [Accepted: 05/19/2014] [Indexed: 11/22/2022]
Abstract
PURPOSE Preoperative chemoradiation therapy (CRT) has become the standard treatment strategy for patients with resectable esophageal cancer. This multicenter phase 2 study investigated the efficacy of the addition of the epidermal growth factor receptor (EGFR) inhibitor panitumumab to a preoperative CRT regimen with carboplatin, paclitaxel, and radiation therapy in patients with resectable esophageal cancer. METHODS AND MATERIALS Patients with resectable cT1N1M0 or cT2-3N0 to -2M0 tumors received preoperative CRT consisting of panitumumab (6 mg/kg) on days 1, 15, and 29, weekly administrations of carboplatin (area under the curve [AUC] = 2), and paclitaxel (50 mg/m(2)) for 5 weeks and concurrent radiation therapy (41.4 Gy in 23 fractions, 5 days per week), followed by surgery. Primary endpoint was pathologic complete response (pCR) rate. We aimed at a pCR rate of more than 40%. Furthermore, we explored the predictive value of biomarkers (EGFR, HER 2, and P53) for pCR. RESULTS From January 2010 until December 2011, 90 patients were enrolled. Patients were diagnosed predominantly with adenocarcinoma (AC) (80%), T3 disease (89%), and were node positive (81%). Three patients were not resected due to progressive disease. The primary aim was unmet, with a pCR rate of 22%. Patients with AC and squamous cell carcinoma reached a pCR of 14% and 47%, respectively. R0 resection was achieved in 95% of the patients. Main grade 3 toxicities were rash (12%), fatigue (11%), and nonfebrile neutropenia (11%). None of the biomarkers was predictive for response. CONCLUSIONS The addition of panitumumab to CRT with carboplatin and paclitaxel was safe and well tolerated but could not improve pCR rate to the preset criterion of 40%.

Abstract
Preoperative chemoradiotherapy has been shown to improve the outcome of patients with esophageal cancer, but because response to this therapy varies, it is desirable to identify in advance individuals who would be unlikely to benefit, in order to avoid unnecessary adverse drug effects. The serum profiles of 84 cytokines and related proteins were determined in 37 patients with esophageal squamous cell carcinoma who received identical neoadjuvant preoperative chemoradiotherapy regimens and underwent surgical resection. Histological response to this therapy was assessed in surgically resected specimens. The serum soluble interleukin-6 receptor (sIL6R) level was significantly higher in 30 patients who failed to achieve a histological complete response (P = 0.005). Multivariate analysis revealed that the increased level of sIL6R was one of several significant independent predictors of an unfavorable outcome (hazard ratio, 2.87; P = 0.017). The increased level of this cytokine in patients who did not obtain a complete response was reproducibly observed in an independent cohort of 34 patients. Esophageal squamous cell carcinoma patients with an increased serum level of sIL6R are predicted to respond poorly to preoperative chemoradiotherapy, therefore, their exclusion from this treatment may be considered. Persistent systemic inflammation is implicated as a possible mechanism of resistance to this therapy.

Abstract
BACKGROUND Higher extent of lymph node dissection (LND) is beneficial in primarily resected esophageal cancer patients by providing accurate staging and better tumor control. Achieving pathological complete response (pCR) after chemoradiotherapy (CRT) also represents better outcome. We studied the controversial question whether higher LND could further improve survival after pCR. METHOD Between 1996 and 2007, Esophageal squamous cell carcinoma (ESCC) patients with pCR after CRT were included. Based on the median number of dissected lymph node, patients were divided into two groups (Group 1: Lower LND; Group 2: Higher LND). We compared the demographic features, perioperative outcomes, recurrence, and survival between groups. RESULTS The cohort comprised 101 patients (100 males and one female) with a mean age of 58 years. There were 56 and 45 patients in Group 1 and 2, respectively. Clinical features and perioperative outcome were similar between groups. During a mean follow-up of 78.8 months, 32 (33.7%) patients died of the disease and 35.8% of patients developed recurrence. There was no difference in locoregional (11.3% vs. 9.5%, P=0.78) or distant recurrence (22.6% vs. 33.3%, P=0.18) between the two groups. Patients with lowest LND also had similar outcomes as those with the highest LND. The 5-year disease specific survival rate was 65 and 64% in Group 1 and 2, respectively. CONCLUSION In ESCC patients, the number of negative lymph nodes had no prognostic impact after pCR.

Abstract
PURPOSE The Functional Assessment of Cancer Therapy-Esophageal (FACT-E) Scale version 4 has been used to assess quality of life in patients with squamous cell carcinoma undergoing chemoradiation. We sought to determine whether this scale can be used to assess quality of life in Korean patients with esophageal cancer undergoing chemoradiation. METHODS The FACT-E scale version 4 was cross-culturally translated into Korean. Its reliability and validity were assessed in a group of 146 esophageal cancer patients who were scheduled for neoadjuvant chemoradiation (CRT). This procedure was followed by esophagectomy that took place between 2007 and 2010 at Asan Medical Center. All patients completed the FACT-E, Hospital Anxiety and Depression Scale (HADS) and Functional Living Index-Cancer (FLIC) questionnaires at baseline (pre-treatment) and 1 month after two cycles of induction chemotherapy followed by CRT. RESULTS In validating the FACT-E, we found high internal consistency coefficients ranging from 0.72 to 0.91. Good convergent and divergent validities were demonstrated by the FLIC and HADS scales. The FACT-E showed good clinical validity and effectively differentiated between patient groups with different performance status ratings and stages. Changes in clinical status were reflected by changes in FACT-E scores, demonstrating responsiveness to neoadjuvant CRT. CONCLUSION The FACT-E has been shown to be a reliable and valid instrument that can now be used to prospectively evaluate the quality of life of Korean patients with esophageal cancer.

Abstract
PURPOSE To define failure patterns and predictive factors in esophageal cancer patients who had a pathologic complete response (pCR) after preoperative concurrent chemoradiotherapy (PCRT). METHODS AND MATERIALS We performed a retrospective analysis of 61 esophageal cancer patients who were enrolled in prospective studies and showed pCR after PCRT. All of the patients had squamous cell carcinoma. Of the patients, 40 were treated with hyperfractionated radiotherapy (4,560 cGy in 28 fractions) with 5-fluorouracil (5-FU) and cisplatin (FP), and 21 patients received conventional fractionation radiotherapy with capecitabine and cisplatin (XP). RESULTS The median follow-up time was 45.2 months (range, 6.5-162.3 months). The 5-year overall survival (OS) and disease-free survival rates (DFS) were 60.2% and 80.4%, respectively. In univariate analysis, age and lymph node (LN) metastasis were poor prognostic factors for OS, and pretreatment weight loss (>2 kg) was a poor prognostic factor for DFS. In multivariate analysis, lymph node metastasis and pretreatment weight loss were independent prognostic factors for OS and DFS. Nine patients (15%) had disease recurrence. Of the nine patients, 5 patients had locoregional failure, 1 patients had distant metastasis, and 3 patients had distant and locoregional failure. In-field failure occurred in 5 patients; out-of-field failure occurred in 1 patient; both in-field and out-of-field failure occurred in 2 patients; and both marginal and out-of-field failure occurred in 1 patient. CONCLUSIONS Even in pCR patients, the most common failure site was within the radiation field, which suggests that more efficient local treatment is needed. Tumor recurrence was more common in patients with older age and with pretreatment weight loss.

Abstract
PURPOSE To determine whether [(18)F]fluorodeoxyglucose positron emission tomography (FDG-PET) can delineate patients with esophageal cancer who may not benefit from esophagectomy after chemoradiotherapy. PATIENTS AND METHODS We reviewed records of 163 patients with histologically confirmed stage I to IVA esophageal cancer receiving chemoradiotherapy with or without resection with curative intent. All patients received surgical evaluation. Initial and postchemoradiotherapy FDG-PET scans and prognostic/treatment variables were analyzed. FDG-PET complete response (PET-CR) after chemoradiotherapy was defined as standardized uptake value ≤ 3. RESULTS Eighty-eight patients received trimodality therapy and 75 received chemoradiotherapy. Surgery was deferred primarily due to medical inoperability or unresectable/metastatic disease after chemoradiotherapy. A total of 105 patients were evaluable for postchemoradiotherapy FDG-PET response. Thirty-one percent achieved a PET-CR. PET-CR predicted for improved outcomes for chemoradiotherapy (2-year overall survival, 71% v 11%, P < .01; 2-year freedom from local failure [LFF], 75% v 28%, P < .01), but not trimodality therapy. On multivariate analysis of patients treated with chemoradiotherapy, PET-CR is the strongest independent prognostic variable (survival hazard ratio [HR], 9.82, P < .01; LFF HR, 14.13, P < .01). PET-CR predicted for improved outcomes regardless of histology, although patients with adenocarcinoma achieved a PET-CR less often. CONCLUSION Patients treated with trimodality therapy found no benefit with PET-CR, likely because FDG-PET residual disease was resected. Definitive chemoradiotherapy patients achieving PET-CR had excellent outcomes equivalent to trimodality therapy despite poorer baseline characteristics. Patients who achieve a PET-CR may not benefit from added resection given their excellent outcomes without resection. These results should be validated in a prospective trial of FDG-PET-directed therapy for esophageal cancer.

Abstract
INTRODUCTION This study was undertaken to determine the outcomes of patients treated for squamous cell carcinoma (SCC) of the oesophagus. METHODS The study group consisted of 61 patients (median age: 64 years) with invasive SCC of the oesophagus who underwent resection between 1987 and 2007 in Adelaide, South Australia. Thirty-two (52%) were female. Survival data were available for all patients. The log rank test was performed to identify prognostic factors for survival. RESULTS The 5-year overall survival rate was 33% (median: 24 months). Of 61 patients, 42 (69%) received neoadjuvant therapy prior to surgery. The overall resection rate was 95%. Significant post-operative morbidity occurred in 47%, and the in-hospital mortality was 5% (30-day mortality: 3%). No overall survival benefit was seen in patients undergoing neoadjuvant therapy prior to surgical resection. However, patients who had a complete pathological response to neoadjuvant therapy had a better 5-year survival than patients who did not receive neoadjuvant therapy: 47% versus 30%, respectively. CONCLUSIONS Oesophagectomy following neoadjuvant therapy for SCC of the oesophagus can be performed with low perioperative mortality. A complete response to neoadjuvant therapy was followed by an improved survival outcome.

Abstract
The incidence of esophageal cancer, in particular esophageal adenocarcinoma, is increasing, largely due to an increase in risk factors for adenocarcinoma. When esophageal cancer is confirmed by upper endoscopy, staging is required for the optimal selection of patients who should undergo esophageal resection. Neoadjuvant chemoradiation may be able to improve survival after esophageal cancer surgery. Endoscopic therapy for early esophageal neoplasia is effective and safe, with the best results being obtained by an individualized approach using endoscopic mucosal resection, ablative therapy, or both. Finally, dysphagia from esophageal cancer can be successfully treated with stent placement or single-dose brachytherapy. Future research should establish whether combinations of chemotherapy with or without radiation therapy play a role in survival.
