Patient: Description of condition (onset time, main symptoms, hospital visited, etc.): Patient male, 57 years old, in November 2009, esophageal cancer was found during physical examination, no physical symptoms. on December 22, 2009, esophageal cancer resection surgery was done in Cancer Hospital of Medical Academy, postoperative pathological results were: carcinoma in situ, no metastasis was found, but cancer was visible 0.2 cm from the outer edge of the upper incision, the lower incision was fine. Postoperative reflux was more serious, and the situation improved after oral omeprazole, and the upper end of the anastomosis had been erosion and inflammation in several reviews. A few days ago, in a review at Jilin Medical University Hospital, a 0.2-0.3 cm protrusion of the upper end of the anastomosis was found, and a pathology was done, which showed: chronic inflammation of the anastomotic mucosa and inflammatory granulation tissue, squamous epithelial hyperplasia with moderate atypical hyperplasia. The lymph nodes are enlarged to 1.7. 1.Is it necessary to do radiotherapy treatment and can I see you? 2.It is said that radiotherapy for esophageal cancer is not obvious and minimally invasive surgery is needed? 3.What is a good treatment for erosion, inflammation and reflux? Hospital: First of all, we should clarify whether the cancer in “cancer visible at 0.2 cm from the outer edge of the upper incision” is also in situ cancer, because sometimes there are cases of in situ cancer and invasive cancer in the esophagus coexisting. If both are carcinoma in situ, then: 1.Postoperative radiotherapy is not recommended after radical surgery for esophageal carcinoma in situ. 2. Relatively speaking, chemotherapy is not sensitive to esophageal cancer, and it is not recommended after radical esophageal carcinoma in situ. 3.At present, endoscopic minimally invasive surgery is mainly used for in situ cancer or early (T1) stage esophageal cancer diagnosed by endoluminal ultrasound. 4.Esophageal celiac inflammation is mainly caused by postoperative reflux. It is recommended to continue to take acid-control drugs, eat less and more meals, lie flat or on the side in an appropriate high pillow position, and review regularly. 5. 1.7cm diameter lymph node should be taken seriously, I don’t know where it is, PET-CT is feasible to characterize it if necessary, if it is confirmed to be metastatic lymph node, it should be treated promptly. Patient: Thank you very much for your patient and detailed answer, which helped us a lot. My father was in the situation you mentioned, and the postoperative pathology showed that “carcinoma in situ was seen on the side inside the upper margin”. We were so surprised by the review that we were at a loss as to whether we should undergo radiotherapy to control the current situation, and we were worried that my father would not accept it if we really had to undergo radiotherapy.
