Long-term disease-free survival after resection of recurrent tumor of esophageal cancer with surrounding multiple visceral organs: a case report

Abstract Background Current guidelines recommend the use of neoadjuvant chemo-radiation (NCR) for the treatment of locally advanced esophageal cancer, both types, adenocarcinoma (AC) and squamous cell carcinoma (SCC). So far, the optimal dose of radiotherapy to achieve a maximal tumor response within an acceptable toxicity is not yet determined. The aim of this study was to assess the impact of preoperative radiation dose on postoperative outcomes and long-term survival. Methods Consecutive patients operated in two European tertiary centers for AC or SCC, treated with NCR and surgery from 2000–2016 were assessed. Specific postoperative complications (i.e. anastomotic leakage, atrial fibrillation), histological tumor regression grade (TRG, Mandard score), overall and disease-free survival were compared among three patients groups: group A (41.4Gy), group B (45Gy), and group C (50.4Gy). The x2 or Fisher test were used for categorical variables and ANOVA for continuous variables. Survival analysis was done with the Kaplan-Meier method and log-rank test. Results There were 294 patients included; 41.5% (n = 122) had AC and 58.5% (n = 172) SCC. Overall, 9.2%/27 patients received 41Gy, 57.8%/170 patients 45Gy and 33%/97 patients received 50.4Gy. Carboplatin-Paclitaxel was the most frequently used chemotherapy for group A (62.9%), and 5FU-Cisplatin for groups B (69.4%) and C (51.5%). Postoperative anastomotic leakage was lower for group B (7.1%) compared to group A (22.2%) and C (13.4%) (P = 0.036), as was the occurrence of atrial fibrillation (11.8% group B, 33.3% group A and 19.6% group C, P = 0.013). Complete or excellent response (TRG 1–2) was significantly better for group B (58.2%), followed by group C (49.5%) and A (25.9%) patients (P = 0.012). Median overall survival was 48, 27 and 29 months for group A, B and C (P = 0.498), and median disease-free survival was 13, 27 and 18 months (P = 0.411), respectively. Conclusion Preoperative radiotherapy dose of 45Gy with 5FU-Cisplatin was associated with a better histological response and less postoperative adverse outcomes compared to 41Gy and 50.4Gy, with no significant differences in long-term recurrence and survival. The role of the type of chemotherapy and histological tumor type are important co-factors affecting outcome and must be further assessed.

Purpose We update Radiation Therapy Oncology Group trial 8911 (USA Intergroup 113), a comparison of chemotherapy plus surgery versus surgery alone for patients with localized esophageal cancer. The relationship between resection type and between tumor response and outcome were also analyzed. Patients and Methods The chemotherapy group received preoperative cisplatin plus fluorouracil. Outcome based on the type of resection (R0, R1, R2, or no resection) was evaluated. The main end point was overall survival. Disease-free survival, relapse pattern, the influence of postoperative treatment, and the relationship between response to preoperative chemotherapy and outcome were also evaluated. Results Two hundred sixteen patients received preoperative chemotherapy, 227 underwent immediate surgery. Fifty-nine percent of surgery only and 63% of chemotherapy plus surgery patients underwent R0 resections (P = .5137). Patients undergoing less than an R0 resection had an ominous prognosis; 32% of patients with R0 resections were alive and free of disease at 5 years, only 5% of patients undergoing an R1 resection survived for longer than 5 years. The median survival rates for patients with R1, R2, or no resections were not significantly different. While, as initially reported, there was no difference in overall survival for patients receiving perioperative chemotherapy compared with the surgery only group, patients with objective tumor regression after preoperative chemotherapy had improved survival. Conclusion For patients with localized esophageal cancer, whether or not preoperative chemotherapy is administered, only an R0 resection results in substantial long-term survival. Even microscopically positive margins are an ominous prognostic factor. After a R1 resection, postoperative chemoradiotherapy therapy offers the possibility of long-term disease-free survival to a small percentage of patients.

Abstract Aim The aim of this study was to assess whether a preoperative HH≥3cm had an impact on histopathologic tumor response after neoadjuvant treatment, as well as on overall and disease-free survival. Background & Methods Hiatal hernia (HH) and long-term gastroesophageal reflux are known risk factors for esophageal cancer. Previous data suggest a negative impact of large hiatal hernias on survival after esophagectomy, as well as an increased toxicity after neoadjuvant treatment (1), although evidence remains scarce and the mechanism is not fully elucidated. All consecutive patients who underwent surgical esophagectomy for adenocarcinoma or squamous cell cancer of the esophagus and gastro-esophageal junction from 2012-2018 were assessed. Baseline oesogastroduodenoscopy reports and CT-scan images were retrospectively reviewed to identify the presence of a HH of ≥3cm (2). Response to neoadjuvant treatment as assessed by the Mandard score (3), postoperative outcomes and survival were compared between HH and non-HH patients (defined as HH<3cm or no HH at all). Categorical variables were compared with the x2 or Fisher’s test, whereas continuous ones with the Mann-Whitney-U test. The Kaplan-Meier method and log-rank test were used for survival analyses. Results Among the 174 included patients, 44 (25.3%) had a HH≥3cm upon diagnosis. HH patients compared to the non-HH had significantly more Barrett’s metaplasia (52.3% vs 20%, p<0.001), although no differences in baseline stage were observed. HH patients presented a worse response to neoadjuvant treatment compared to non-HH patients (TRG 4-5 in 40.5% vs 21.3%, p=0.033). Among HH patients, perioperative chemotherapy compared to radiochemotherapy showed a trend to higher complete response rates (TRG 1 in 25% vs 11.5%, p=0.059). In the radiochemotherapy subgroup (n=112), HH patients had worse complete response rates than non-HH patients (TRG 1 in 11.5% vs 26.7% respectively, p=0.050). However, no differences in overall or disease-free survival were observed between HH and non-HH patients in the whole cohort or in subgroup analyses. Conclusion A HH≥3cm is frequently encountered in esophageal cancer patients. The presence of HH was associated with worse response to neoadjuvant treatment, especially radiochemotherapy. However, the presence HH did not have an impact on long-term survival and recurrence.
