“…The occurrence of cancer is in the areas of narrowing and strictures in the esophagus, therefore, it is in these places that endoscopists, during the exams, need to focus their attention, in order to search for pre-neoplastic lesions (5,9,16) The survival rate of patients with esophageal squamous cell carcinoma depends on the staging at the time of diagnosis and oncological and surgical treatment options (13,19). However, the authors have reported a 5-year survival rate of 45-50% and a 10-year survival rate of approximately 15% in patients undergoing esophagectomy with neoplasms associated with caustic ingestion.…”

“…Esophagocoloplasty is an option when the stomach cannot be used. Ruol et al reported in the analyzed series that the gastrointestinal tract was reconstructed with intrathoracic esophagogastroplasty in 8 cases, cervical esophagogastroplasty in 7 cases and cervical esophagogastroplasty in 2 cases (19).…”

Caustic ingestion remains a complex public health issue worldwide, in adults and children. Caustic agent (acids and alkalis) is a product that causes tissue damage, and its ingestion will damage the mouth, pharynx, hypopharynx, esophagus, stomach, duodenum, and may reach the jejunum. Concomitant gastric and intestinal injuries can occur in 20 to 60% (1-3) Acid products, most of the times, cause coagulative necrosis of the mucosa, while alkalis cause a liquefaction/saponification effect on the mucosa, reaching the entire wall of the organ. The most accessible acids are hydrochloric, sulfuric and oxalic acid, widely used in civil construction and factories. Products that contain alkali are those used in household cleaning, containing sodium hydroxide, also known as caustic soda. Therefore, caustic stenosis of the esophagus depends on the product ingested, the amount that was ingested and its concentration (1, 4-6).Ingestion of these products damages the esophagus, in different extensions, and the final consequence is progression to stenosis and fibrosis of the organ. The most common symptom is dysphagia, and the intensity of dysphagia depends on the degree of stenosis. Odynophagia is also present. The nutritional status injury is evident, due to significant weight loss (1,2,4,7).Developing countries have a higher incidence of this kind of accident. In children under 10 years of age, ingestion is most often accidental, however, in adolescents and adults, the etiology of ingestion is due to attempted suicide. In the United States, despite the decline in caustic intake in children (5,000 to 15,000 per year), the incidence is 15.8 cases per 100,000 peoples (8).

“…Several studies have found that pathological tumor response (PTR), such as tumor regression grade (TRG) and downstaging, was a prognostic factor for patients with esophageal cancer who received neoadjuvant treatment [16][17][18][19]. This study compared the differences in pCR rate, major pathological response (MPR) rate, TRG, downstaging, and event-free survival (EFS) between nICT and nCT groups to investigate whether neoadjuvant immunochemotherapy was superior to chemotherapy alone in patients with esophageal cancer.…”

Neoadjuvant PD-1 blockade combined with chemotherapy is not superior to neoadjuvant chemotherapy alone in resectable locally advanced esophageal carcinoma

Background Neoadjuvant chemotherapy (nCT) or neoadjuvant chemoradiotherapy followed by surgery has been recommended as standard treatment in patients with locally advanced esophageal cancer (LAEC). But the risk of tumor recurrence still remained, and many patients refused or abandoned radiotherapy because of the intolerable adverse effects in China. Neoadjuvant immunochemotherapy (nICT) followed by surgery has become an emerging treatment in patients with esophageal cancer. There was still no consensus on whether nICT was superior to nCT alone in patients with esophageal cancer. Methods In this retrospective study, patients with resectable esophageal cancer who received surgery after nICT (n=26, 40%) or nCT alone (n=39, 60%) were included. The patients were classified as nICT or nCT arm. The primary endpoints were pathological tumor response (PTR) and event-free survival (EFS). The different clinic-pathological features were compared by the Kruskal-Wallis test for continuous variables and the Chi-square (χ2) test for categorical variables. Kaplan-Meier curves were used to estimate EFS from the date of treatment to recurrence or death. All tests were 2-sided with a significative P-value defined <.05. Results Three (11.5%) of the 26 patients achieved pathological complete remission (pCR) in the nICT group, and four (10.3%) of the 39 patients achieved pCR in the nCT group, respectively (P=1.000). Six (23.1%) of the 26 patients achieved major pathological response (MPR) in the nICT group, and 11 (28.2%) of the 39 patients achieved MPR in the nCT group, respectively (P=0.645). Downstaging was achieved in 13 (44.8%) patients in the nICT group and 16 (55.2%) patients in the nCT group, respectively (P=0.732). To verify the tumor regression grade (TRG) results, we compared them with MPR and pCR, which showed a significant dependency (P< 0.001). Patients who achieved downgrading showed better MPR and pCR rates (P<0.001 and P =0.010). There was no significant difference in EFS between the nICT and nCT groups (HR=1.011, 95% CI: 0.421–2.425, P = 0.981). Conclusions Neoadjuvant PD-1 blockade combined with chemotherapy was not superior to chemotherapy alone for patients with resectable locally advanced esophageal carcinoma. However, more studies with long-term follow-up were needed to confirm this result.

Background Neoadjuvant concurrent chemoradiotherapy with surgery was the standard of therapy for esophageal cancer. But many patients refused or abandoned radiotherapy because of the intolerable adverse effects in China. Neoadjuvant immunochemotherapy (nICT) followed by surgery has become an emerging treatment in patients with esophageal cancer. There was still no consensus on whether neoadjuvant immunochemotherapy was superior to neoadjuvant chemotherapy (nCT) alone in patients with esophageal cancer.

Kaplan-Meier curves were used to estimate EFS from the date of treatment to recurrence or death. All tests were 2-sided with a significative P-value defined < .05. Results Three (11.5%) of the 26 patients achieved pathological complete remission (pCR) in the nICT group, and four (10.3%) of the 39 patients achieved pCR in the nCT group, respectively (P = 1.0).
