Overview of cancer treatments Surgical treatment
Surgery is a primary treatment for early and some
locoregional stomach cancers. Primary treatment is
the main treatment used to rid the body of cancer.
The goal of surgery is to remove the entire tumor
and some normal-looking tissue around its rim. The
normal-looking tissue is called the surgical margin. A
margin width of 4 cm or greater is advised.
You will be given instructions on how to prepare for
your surgery. The week before your surgery you may
have to stop taking some medicines. On the day of
your surgery, you should not eat or drink. General
anesthesia will be used. In some people, general
anesthesia causes nausea with vomiting, confusion,
muscle aches, and itching.
A gastrectomy is a surgery that removes some or all
of the stomach.
See Figure 11.
The stomach tumor
may have grown into nearby structures. In this case,
the stomach and other tissue should be removed
together and not in pieces. Removal of your spleen is
not required unless cancer is present.
How much of your stomach will be removed depends
on the extent of the cancer. A total gastrectomy
removes your whole stomach. A subtotal gastrectomy
removes part of your stomach. A distal gastrectomy
is a subtotal gastrectomy of the lower half of your
stomach. A proximal gastrectomy is a subtotal
gastrectomy of the upper half of your stomach.
