Abstract
BACKGROUND The optimal treatment strategy for resectable cervical esophageal cancer (CEC) remains controversial. This study aimed to explore prognostic factors and optimal treatment strategies in the context of staging. METHODS In this population-based study, 1371 patients with resectable CEC were identified in the SEER database. Univariate analysis and multivariable Cox regression model were performed to evaluate factors related to overall survival (OS). Subgroup analysis based on staging was performed to assess the effect of treatments on survival and propensity score matching (PSM) was conducted to adjust confounding factors. RESULTS Univariate and multivariable analyses revealed that age, sex, year of diagnosis, histological type, tumor size, cN stage, surgery, radiotherapy and chemotherapy are independent prognostic factors. After PSM, patients with local disease (cT1-2N0M0) who received surgery alone had a higher 10-year OS rate than those received chemoradiotherapy (CRT) (20.7% vs. 11.4%, p = 0.023). Compared with CRT, surgery-based multimodal therapy did not increase the OS rate of patients (14.8% vs. 11.1%, p = 0.084). For regional disease (cT3-4aN0M0/cT1-4aN1-3M0), although surgery alone did not improve the OS rate of patients compared with CRT (7.3% vs. 8.2%, p = 0.18), we observed a significant difference in 10-year OS among patients who underwent surgery-based multimodal therapy versus those who underwent CRT (20.4% vs. 9.0%, p = 0.031). CONCLUSIONS Compared with CRT, surgery alone improves the long-term survival of patients with localized disease, and surgery-based multimodal therapy increases the survival rate of patients with regional disease. Further studies are required to confirm our findings.

Adjuvant Radiotherapy of Involved Field versus Elective Lymph Node in Patients with Operable Esophageal Squamous Cell Cancer: A Single Institution Prospective Randomized Controlled Study. J Cancer 2021; 12:3180-3189. [PMID: 33976727 PMCID: PMC8100799 DOI: 10.7150/jca.50108] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2020] [Accepted: 02/03/2021] [Indexed: 01/04/2023] Open
Abstract
Background: To evaluate locoregional failure and its impact on survival by comparing involved field irradiation (IFI) with elective lymph node irradiation (ENI) for patients with esophageal squamous cell cancer who underwent post-operative radiotherapy. Methods and Materials: The enrolled patients were randomized allocated to IFI or ENI group. CTV of IFI was generated according to pre-operative primary tumor location and post-operative pathological characters and positive LNs regions. CTV of ENI was generated according to pre-operative tumor position to administer selective lymph node irradiation. Radiotherapy planning was delivered using either 3D-CRT or IMRT. Results: A total of 57 patients were enrolled, 28 patients in ENI group and 29 patients in IFI group. There were not statistical differences between two groups in baseline (p>0.05). The initial locoregional failure rate was 17.9 % in ENI arm and 20.7% in IFI arm respectively (p=0.085). The 1-, 3-, and 5-year Progression-free Survival (PFS) were 63.2, 43.5, and 21.8 % in ENI arm versus 78.2, 60.1, and 55.1% in IFI arm (p =0.038). The 1-, 3-, and 5-year overall survival (OS) were 78.6, 46.9, and 23.5 % in ENI arm versus 72.9, 59.7, and 54.3 % in IFI arm (p=0.06). Acute radiation pneumonitis (p=0.005) and hematological toxicities (p =0.029) also showed statistical differences between groups, ENI arm was more than IFI arm. Conclusions: The results indicated that IFI tended to improve survival and reduce toxicities for patients with operative ESCC and did not increase locoregional failure compared to ENI. It is thus suggested that IFI for ESCC PORT is worthy of clinical recommendation and further study.

Abstract
Multidisciplinary therapies can improve the survival of patients with locally advanced esophageal carcinoma. However, the determination of the optimal modality is still a controversial subject. Many randomized controlled trials in the late 20th century showed that there was no survival benefit when postoperative radiotherapy was added to surgery for esophageal carcinoma. As a result, the treatment modality shifted thereafter to neoadjuvant therapies. Even so, these trials are criticized for many limitations and an increasing number of studies (mainly nonrandomized controlled trials) has indicated that postoperative radiotherapy/chemoradiotherapy can improve the survival of patients with a poor prognosis after R0 esophagectomy. Additionally, a large number of patients with locally advanced esophageal carcinoma still choose upfront surgery in the clinical practice due to many reasons. Therefore, postoperative radiotherapy seems to be a feasible treatment for these patients with a poor prognosis, particularly in the new era of conformal radiotherapy. Here, we review published studies on postoperative radiotherapy/chemoradiotherapy, and we discuss the clinical issues related to postoperative radiotherapy, such as the indication, target volume, total radiation dosage, time interval and complications of postoperative radiotherapy with or without chemotherapy, to make recommendations of postoperative radiotherapy for both current practice and future research in esophageal carcinoma.

Abstract
OBJECTIVE Inconclusive results are available as to whether chemo/radiotherapy should be administered to resectable esophageal cancer patients before surgery (neoadjuvant therapy) or after surgery (adjuvant therapy). The paper, via a meta-analysis of effects of treatment modalities when administering chemo/radiotherapy, aims to systematically evaluate the effect of timing of chemo/radiotherapy and surgery. METHODS We performed a systematic literature search for clinical trials of neoadjuvant and adjuvant therapy for patients with esophageal cancer. Using meta-analysis, we conducted direct and adjusted indirect comparisons of overall survival, complete resection rate (R0 resection), perioperative mortality, leakage rate and local recurrence in patients with resectable esophageal cancer. RESULTS A total of 32 studies involving 7985 patients with esophageal cancer were included in the meta-analysis. Twenty-five randomized controlled studies indirectly compared neoadjuvant/adjuvant therapy with surgery alone, while five non-randomized controlled studies and two randomized controlled studies directly compared neoadjuvant with adjuvant therapy. Neoadjuvant therapy followed by surgery, compared with surgery along with adjuvant therapy, showed a significant overall survival advantage in our pooled analysis (HR 0.88; 95% CI 0.79-0.98). Directly compared with adjuvant therapy, neoadjuvant therapy demonstrated a lower local recurrence rate (OR 0.56; 95% CI 0.43-0.74) with low heterogeneity (I2 = 1%). Neoadjuvant therapy, comparing to surgery with or without adjuvant therapy, showed a significantly higher R0 resection rate (OR 2.86; 95% CI 2.02-4.04) with moderate heterogeneity (I2 = 38%) and no significant differences in postoperative anastomotic leakage (P = 0.50). However, neoadjuvant therapy, compared with surgery adjuvant therapy, significantly increased perioperative mortality in both direct and indirect comparisons (P < 0.01). CONCLUSIONS We found that neoadjuvant therapy was associated with higher overall survival and R0 resection rate without increasing postoperative anastomotic leakage for patients with resectable esophageal cancer, whereas neoadjuvant therapy was associated with higher perioperative mortality after esophagectomy.

World J Surg Oncol 2018; 16:216. [PMID: 30404621 PMCID: PMC6223077 DOI: 10.1186/s12957-018-1516-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2018] [Accepted: 10/23/2018] [Indexed: 12/19/2022] Open
Abstract
Background This study evaluated the impact of adjuvant therapies on patient survival and disease recurrence patterns to identify an effective adjuvant therapy for resected lower thoracic oesophageal squamous cell carcinoma (LTESCC). Methods Clinical data of 127 patients with stage IIa-IVa LTESCC with a minimum 2-year follow-up after oesophagectomy were analysed. The survival and recurrence patterns were compared among patients who received adjuvant radiotherapy, adjuvant chemotherapy, adjuvant chemoradiotherapy, or surgery alone. Results Eighty-eight patients (69.3%) were identified as having disease recurrence. The regional lymph node recurrence rate was 57.5%, and the recurrence rates were high in the lower neck, upper mediastinum, and upper abdomen. Compared to surgery alone, adjuvant radiotherapy or chemoradiotherapy significantly decreased the recurrence rate (p < 0.05). Adjuvant chemoradiotherapy significantly improved overall survival, disease-free survival, and locoregional recurrence-free survival compared to surgery alone (p = 0.01, 0.01, and 0.00, respectively). Pathologically positive lymph nodes (PPLNs) in the lower mediastinum represented a potential risk factor for cervical recurrence (HR 2.97, 95%CI 1.19–7.39). Multivariable analysis showed that postoperative radiotherapy (HR 0.30, 95%CI 0.13–0.68) and PPLNs in the upper mediastinum (HR 3.72, 95%CI 1.30–10.67) were independent risk factors for upper mediastinal recurrence, while postoperative radiotherapy (HR 0.37, 95%CI 0.16–0.85) and PPLNs in the abdomen (HR 2.57, 95%CI 1.12–5.92) were independent risk factors for abdominal recurrence. Conclusion Adjuvant chemoradiotherapy was the most effective adjuvant therapy for resected stage IIa-IVa LTESCC. The lower neck, upper mediastinum, and upper abdomen were high-risk regions for postoperative radiotherapy. The regions of PPLNs may be important factors for individual targets.
