1. What are the early symptoms of esophageal cancer?
Early symptoms often include a foreign-body sensation during swallowing or retrosternal discomfort, especially with dry or hard food. Progressive difficulty swallowing may develop,
2. What causes esophageal cancer?
Risk factors include long-term smoking and drinking, very hot and pickled foods, nitrosamine intake, and malnutrition. Gastroesophageal reflux disease and Barrett's esophagus increase adenocarcinoma risk.
3. What types of esophageal cancer surgery are available?
Early disease may undergo endoscopic mucosal resection or submucosal dissection. Advanced disease requires esophagectomy with nodal dissection and digestive tract reconstruction.
4. What is minimally invasive treatment for esophageal cancer?
Early superficial cancer can be removed endoscopically through mucosal resection or submucosal dissection, without opening the chest or abdomen.
5. What is the role of chemoradiotherapy in esophageal cancer?
Neoadjuvant chemoradiotherapy shrinks tumors before surgery and increases resection rates. Postoperative adjuvant chemoradiotherapy reduces recurrence risk. It is standard treatment for inoperable locally advanced disease.
6. What treatments are available for advanced esophageal cancer?
Systemic treatment is the main approach. Chemotherapy controls progression, while immunotherapies such as pembrolizumab and camrelizumab are used for advanced esophageal cancer.
7. How should nutrition be managed in esophageal cancer?
Difficulty swallowing often causes malnutrition, requiring nutritional support. Nutritional assessment is needed before treatment, with a feeding tube or gastrostomy if necessary.
