The oligometastatic and oligoprogressive state has been a hot issue in cancer research. Its indolent tumor behavior, representing a novel therapeutic opportunity, has been identified as a clinical subtype in several malignancies. However, the clinical implications of the oligometastatic and oligoprogressive state in esophageal squamous cell carcinoma (ESCC) have not been thoroughly elucidated. There are still controversies regarding the existence of the oligometastatic state in ESCC, if the solitary regional lymph node metastasis should be viewed as oligoprogressive disease after esophagectomy, and the role of surgery and radiotherapy in ESCC oligometastatic disease. Despite many exciting contributions to the literature on these, further exploration is warranted. Thus, fostering the advance of research and scientific knowledge on the biological and prognostic characteristics scrupulously would facilitate personalizing treatment strategy for better outcomes.

2.Neoadjuvant therapy in locally advanced esophageal squamous cell carcinoma.
Chinese Journal of Gastrointestinal Surgery 2023;26(4):312-318
The efficacy of surgery alone for locally advanced esophageal squamous cell carcinoma (ESCC) is limited. In-depth studies concerning combined therapy for ESCC have been carried out worldwide, especially the neoadjuvant treatment model, including neoadjuvant chemotherapy (nCT), neoadjuvant chemoradiotherapy (nCRT), neoadjuvant chemotherapy combined with immunotherapy (nICT), neoadjuvant chemoradiotherapy combined with immunotherapy (nICRT), etc. With the advent of the immunity era, nICT and nICRT have attracted much attention from researchers. An attempt was thus made to take an overview of the evidence-based research advance regarding the neoadjuvant therapy of ESCC.

Recent advances in multimodality treatment offer excellent opportunities to rethink the paradigm of perioperative management for locally advanced esophageal squamous cell carcinoma. One treatment clearly doesn't fit all in terms of a broad disease spectrum. Individualized treatment of local control of bulky primary tumor burden (advanced T stage) or systemic control of nodal metastatic tumor burden (advanced N stage) is essential. Given that clinically applicable predictive biomarkers are still awaited, therapy selection guided by diverse phenotypes of tumor burden (T vs. N) is promising. Potential challenges regarding the use of immunotherapy may also boost this novel strategy in the future.

Surgery is the main treatment for resectable esophageal squamous cell carcinoma. However, for patients with locally advanced lesions, surgery-based comprehensive treatment is the best treatment strategy. According to the results of some randomized controlled clinical studies and meta-analysis, preoperative neoadjuvant therapy is recommended to improve the survival rate of patients. Neoadjuvant therapy includes neoadjuvant chemotherapy, chemoradiotherapy, targeted therapy and immunotherapy. Great progress has been made in neoadjuvant therapy, but there are still many clinical problems that need to be solved urgently, including the efficacy and safety of neoadjuvant therapy, the choice of neoadjuvant regimen and treatment cycle, the best combination and advantages of multimodal treatment, and the selection of responders to treatment, etc. This article provides a systematic review of the latest developments and existing controversies in neoadjuvant therapy for esophageal squamous cell carcinoma.

An esophageal squamous cell carcinoma measuring 18.3 cm in length and 5 cm in diameter was found in the mediastinum of a 53-year man. The patient underwent a modified 3-stage esophagectomy and an esophagogastrostomy at the cervical level (Wu's method). The operation was performed smoothly and the patient recovered uneventfully after the operation. The patient was followed up for 6 months after discharge and reported no difficulties in eating with improved quality of life. This case represents the world's longest esophageal cancer that had been surgically removed. Local advanced esophageal cancer should be removed immediately to prevent potential occurrence of esophageal obstruction, tracheoesophageal fistula or aorto-esophageal fistula.

Objective: To analyze clinicopathological features of circumferential superficial esophageal squamous cell carcinoma and precancerous lesions and investigate the risk factors for deep submucosal invasion and angiolymphatic invasion retrospectively. Methods: A total of 116 cases of esophageal squamous epithelial high-grade intraepithelial neoplasia or squamous cell carcinoma diagnosed by gastroscopy, biopsy pathology and endoscopic resection pathology during November 2013 to October 2021 were collected, and their clinicopathological features were analyzed. The independent risk factors of deep submucosal invasion and angiolymphatic invasion were analyzed by logistic regression model. Results: The multivariate logistic regression analysis showed that drinking history (OR=3.090, 95% CI: 1.165-8.200; P<0.05), The AB type of intrapapillary capillary loop (IPCL) (OR=11.215, 95% CI: 3.955-31.797; P<0.05) were the independent risk factors for the depth of invasion. The smoking history (OR=5.824, 95% CI: 1.704-19.899; P<0.05), the presence of avascular area (AVA) (OR=3.393, 95% CI: 1.285-12.072; P<0.05) were the independent factors for the angiolymphatic invasion. Conclusions: The risk of deep submucosal infiltration is greater for circumferential superficial esophageal squamous cell carcinoma patients with drinking history and IPCL type B2-B3 observed by magnifying endoscopy, while the risk of angiolymphatic invasion should be vigilant for circumferential superficial esophageal squamous cell carcinoma patients with smoking history and the presence of AVA observed by magnifying endoscopy. Ultrasound endoscopy combined with narrowband imagingand magnification endoscopy can improve the accuracy of preoperative assessment of the depth of infiltration of superficial squamous cell carcinoma and precancerous lesions and angiolymphaticinvasion in the whole perimeter of the esophagus, and help endoscopists to reasonably grasp the indications for endoscopic treatment.

This study was undertaken to examine prognosis after resection for M1 disease in squamous cell esophageal carcinoma. Fifty-six patients with M1 esophageal cancer underwent esophageal resection with two or three-field nodal dissection from 1994 to 2001. Operative mortality occurred in 3 patients. Primary tumor sites were as follows; 10 upper, 23 middle, and 20 lower thoracic esophagus. They were found to have M1 disease by pathologic examination of dissected nodes, 24 M1a and 29 M1b. Forty-two patients (79%) were considered to have undergone curative resection. Chemotherapy and/or radiation therapy was given to 38 patients perioperatively. Recurrence was identified in 35 patients (66%) during a mean follow-up of 23 months. Overall median and 5-yr survivals were 19 months and 12.7%. Five-year survivals for M1a and M1b disease were 23.9% and 6.1%, respectively (p=0.0488). Curative resection tended to show better survival (p=0.3846). Chemotherapy and/or radiation therapy provided no advantage (p=0.5370). Multivariate analysis showed that M1b was significant risk factor over M1a disease. Our conclusion is that surgical resection can provide acceptable survival in thoracic squamous esophageal cancer with M1a disease. Survival differences between M1a and M1b disease support the current subclassification staging system.

9.Pattern of lymph node metastasis and choice of lymphadenectomy in patients with thoracic esophageal squamous cancer.
Chinese Journal of Gastrointestinal Surgery 2018;21(9):987-994
Esophageal squamous cancer is a malignancy with high incidence and mortality. Surgery currently remains the most important part of the comprehensive treatments. The number of metastatic lymph node has great influence on the prognosis of esophageal cancer, so thorough lymphadenectomy also becomes a key factor. Meanwhile, the choice of lymphadenectomy procedure during surgery has always been controversial. In current article, we summarized the pattern in lymph node metastasis in thoracic esophageal squamous cell carcinoma by analyzing relevant literatures, and discovered that the longitudinal lymphatic network of the submucosa and the horizontal lymphatic pathways of the muscularis propria are the anatomical foundation of the lymph node metastasis of esophageal cancer. Then, we evaluated the impact of lymph node metastasis on the prognosis in terms of number of metastatic lymph node, distant metastasis, positive lymph node ratio, solitary metastasis, micrometastasis and extracapsular lymph node involvement. During surgery, should we choose two-field lymphadenectomy (2-FL) or three-field lymphadenectomy (3-FL)? The clinical efficacy was compared between 2-FL and 3-FL in this paper. The results showed that compared with patients who underwent 2-FL, those who underwent 3-FL had significantly higher 5-year survival rate, significantly longer operative time, and more dissected lymph nodes, while blood loss during surgery was not significantly different. As for complication, some studies indicated that patients after 3-FL had a significantly higher risk of anastomotic leakage, recurrent laryngeal nerve paralysis, and tracheal ischemia, while no significant differences in pulmonary infection and chylothorax were found. At last, we introduced the application of sentinel lymph node technique and relevant research evidence of recurrent laryngeal nerve lymph node as predictive markers for cervical lymph node metastasis.

Objective: To evaluate the efficacy and safety of neoadjuvant chemotherapy combined with programmed death-1 (PD-1) antibody in operable, borderline or potentially resectable locally advanced esophageal squamous cell carcinoma(ESCC) in the real world. Methods: The study retrospectively analyzed 28 patients with operable or potentially resectable locally advanced ESCC patients treated with preoperative chemotherapy combined with PD-1 inhibitor in Nanjing Drum Tower Hospital, Affiliated Hospital of Nanjing University Medical School from April 2020 to March 2021. According to the clinical TNM staging system of the 8th edition of the American Joint Committee on Cancer, there were 1, 15, 10, 1 and 1 case of stage Ⅱ, Ⅲ, ⅣA, ⅣB and unknown stage respectively. The treatment was two cycle of dual drug chemotherapy regimen including taxane plus platinum or fluorouracil combined with PD-1 antibody followed by tumor response assessment and surgery if the patient was eligible for resection. Results: Of the 28 patients, 1, 2, 3 and 4 cycles of chemotherapy combined with PD-1 antibody treatment completed in 1, 21, 5, and 1 patient, respectively. Objective response rate (ORR) was 71.4% (20/28), and disease control rate (DCR) was 100% (28/28). The incidence of adverse events exceeding grade 3 levels was 21.4% (6/28), including 3 neutropenia, 1 leukopenia, 1 thrombocytopenia and 1 immune hepatitis. There was no treatment-related death. Of the 23 patients underwent surgery, R0 resection rate was 87.0% (20/23), 13 patients had down staged to the T1-2N0M0 I stage, the pCR rate was 17.3% (4/23), and the pCR rate of primary tumor was 21.7% (5/23). Four patients received definitive chemoradiotherapy. One patient rejected surgery and other treatment after achieved PR response. Conclusion: Neoadjuvant chemotherapy combined PD-1 inhibitor is safe and has high efficacy in operable, borderline or potentially resectable locally advanced ESCC, and it is a promising regimen.
