Treatments For Lung Cancer Stage 1
Lung cancer treatments depend on the type of cancer, the stage of the cancer (how much it has spread), age, health status, and additional
personal characteristics. As there is usually no single treatment for cancer,
patients often receive a combination of therapies and palliative care. The main
lung
cancer treatments are surgery, chemotherapy,
and/or radiation. However, there also have been recent developments in the
fields of immunotherapy, hormone therapy, and gene therapy.
Surgey
Surgery is the oldest known treatment for cancer. If a cancer is in stage I or II and
has notmetastasized,it is possible to completely cure a patient by surgically
removing the tumor and the nearby lymph nodes.After the disease has spread,
however, it is nearly impossible to remove all of the cancer cells.
Surgery
is rarely the main treatment for small cell lung cancer—fewer than 5 percent of patients are
goodcandidates,meaning the cancer is confined to one lung and has not spread to
lymph nodes. But it offers the best chance of curingearlystage,nonsmallcell lung cancer and is often used with chemotherapy or radiation
for more advanced disease.
Lung cancer surgery is performed by aspecially trained thoracic
surgeon. Afterremoving the tumor and the surroundingmargin of tissue, the
margin is further studiedto see if cancer cells are present. If no canceris found in the tissue surrounding
the tumor, itis considered a "negative margin." A
"positivemargin" may require the surgeon to removemore of the lung
tissue.
Lung
surgeries are complex operations with potentially serious consequences, so they
are best handled by experiencethoracic surgeons like ours. We use the latest
research and technology to diagnose and treat patients, and offer a fullrange
of procedures—including minimally invasive surgery or interventional
pulmonology for some cancers.
Lung cancer surgery can
be curative or palliative. Curative surgery aims to cure a patient with early
stagelung cancer by removing all of the cancerous tissue. Palliative surgery
aims to remove an obstruction oropen an airway, making the patient more
comfortable but not necessarily removing the cancer.
Radiation
Radiation treatment, also known as radiotherapy, destroys or
shrinks lung cancer tumors by
focusinghighenergyrays on the cancer cells. This causes damage to the molecules
that make up the cancercells and leads them to commit suicide. Radiotherapy
utilizes ighenergy Gammaraysthat are emittedfrom metals such as radium or
highenergyxraysthat arereated in a special machine. Radiation canbe used as the
main treatment for lung cancer, to kill
remaining cells after surgery, or to kill cancer cellsthat have metastasized.
Radiation
therapy uses highenergyXraysor other radiation to kill cancer cells or stop them from growing. Someexamples of
when we use radiation for lung cancer treatments include:
- · After surgery to prevent cancer from returning
- · With chemotherapy
- · By itself—either to treat tumors when patients can’t or don’t want to have surgery or to relieve latestagediseasesymptoms
- · Before surgery, to shrink a tumor
- · To the brain, to make sure small cell lung cancer does not spread there after otherwise successful treatment
If
the lung cancer is very large or has involvement of the lymph nodes, radiation therapy
can be acurative option when given at the same time as chemotherapy. The length of
treatment will be 6-7weeks. The majority of patients will be treated on the
Tomotherapy machine, which delivers radiationusing a technique called intensity
modulated raidation therapy (IMRT), with automatic image-guidedradiation
therapy. Generally, IMRT will allow for greater normal lung sparing compared to
traditionaltechniques, and also help minimize exposure to other nearby organs,
such as the esophagus and heart.
Early radiation treatments caused severe sideeffectsbecause the
energy beams would damage normal,healthy tissue, but technologies have improved
so that beams can be more accurately targeted.Radiation oncologists can focus
the radiation in precise
locations in the body for certain lengths of time,reducing the risk of damage
to surrounding healthy tissue. Treatments occur intermittently over weeks
ormonths depending on the size and extent of the tumor, the dosage of
radiation, and how much damage isbeing done to noncancerous tissue.
We
offer the latest, safest radiation treatments, including 4D computed tomography
(CT) and respiratory gating to adjustfor tumor movement and CyberKnife for
delivering therapy with laserlikeprecision. Initial results from our clinical trialshow that CyberKnife is as effective as surgery for treating
earlystage,nonsmallcell cancer—good news for patientstoo frail or ill for an
operation.
Common side effects of radiation
therapy include fatigue, nausea, loss of appetite, hair loss, and
skinaffectations that cause skin to become dry, irritated, and sensitive.
