There are two major types of gastric adenocarcinoma including the following:
Intestinal adenocarcinomas are well differentiated, and the cells tend to arrange themselves in tubular or glandular structures. The terms tubular, papillary, and mucinous are assigned to the various types of intestinal adenocarcinomas. Rarely, adenosquamous cancers can occur.
Caregivers need help and emotional support.
A caregiver responds in his or her own way to the cancer patient's diagnosis and prognosis. The caregiver may feel emotions that are as strong as or stronger than those felt by the patient. The caregiver's need for information, help, and support is different from what is needed by the patient.
The life of a family caregiver changes in many ways when cancer is diagnosed. These changes affect most parts of life and continue after treatment ends.
Diffuse adenocarcinomas are undifferentiated or poorly differentiated, and they lack a gland formation. Clinically, diffuse adenocarcinomas can give rise to infiltration of the gastric wall (i.e., linitis plastica).
Some tumors can have mixed features of intestinal and diffuse types.
