Yes, esophageal squamous-cell carcinomas (ESCC) and esophageal adenocarcinomas (EAC).
Esophageal cancer
Most esophageal cancers fall into one of two classes: esophageal squamous-cell carcinomas (ESCC), which are similar to head and neck cancer in their appearance and association with tobacco and alcohol consumption—and esophageal adenocarcinomas (EAC), which are often associated with a history of GERD and Barrett's esophagus

Esophageal cancer [SEP] Types
Esophageal cancers are typically carcinomas that arise from the epithelium, or surface lining, of the esophagus. Most esophageal cancers fall into one of two classes: esophageal squamous-cell carcinomas (ESCC), which are similar to head and neck cancer in their appearance and association with tobacco and alcohol consumption—and esophageal adenocarcinomas (EAC), which are often associated with a history of GERD and Barrett's esophagus. A rule of thumb is that a cancer in the upper two-thirds is likely to be ESCC and one in the lower one-third EAC. Rare histologic types of esophageal cancer include different variants of squamous-cell carcinoma, and non-epithelial tumors, such as leiomyosarcoma, malignant melanoma, rhabdomyosarcoma and lymphoma, among others.
