Your Cancer Surgery Guide
In simple terms Lung Cancer can be defined as growth of abnormal cells uncontrollably either in one or both of the lungs. These cells destroys the proper functioning of normal lung cells and develop the healthy lung tissues.
With the growth of these abnormal cells they can also result into tumors or even interrupt the functioning of the lung.
Symptoms which indicate that you are suffering from Lung Cancer are as follows -
These are some of the symptoms of Lung Cancer which should be reported to doctor. Although these can be attributed to other diseases like bronchitis or pneumonia etc. But precaution is better than cure.
Lung Cancer consists of two major types one is Non - Small cell Lung Cancer (NSCLC) and other one is Small Cell Lung Cancer (SCLC).
Around 85% of the patients of Lung Cancer are suffering from the Non-Small Cell Lung Cancer and remaining 15% patients are suffering from the Small Cell Lung Cancer.
Treatments of Lung CancerThe treatment of Lung Cancer also varies according to its types -
Non-Small Cell Lung Cancer TreatmentThere are plenty of methods of treat non small cell lung cancer treatment such as Immunotherapy, targeted treatments, Chemotherapy, Surgery, radiation etc either single or in a combination of each other.
However, each type may cause some side effects. Let’s discuss each treatment in detail -
Surgery Most of the non-small cell lung cancers are treated with surgery mostly at the stage of Stage l and Stage ll. While performing the surgery a surgeon has to remove the lobe or section of the lung containing the tumor.
Many surgeons use VATS (Video - assisted thoracoscopic surgery) in which they use to make a small cut or incision and insert a small tube in our body referred as thoracoscope. This tube has a very tiny camera as well as light connected to video monitor through which surgeon can look inside the chest.
Thereafter it can be removed through the scope without making a large cut into the body.
Chemotherapy and Radiation
Researches proved that chemotherapy after surgery helps preventing the cancer from returning also known as adjuvant chemotherapy.
Chemotherapy generally proved beneficial for patients suffering from stage ll and stage lll A disease.
Stage l and stage ll can only be treated from the surgery but people who are suffering at the lll stage doctors often recommend chemotherapy combining with definitive radiation treatments.
However, stage lV is cured only by radiation for palliation of symptoms.
This treatment consists of combination of drugs and most commonly used drugs in Chemotherapy are cisplatin (Platinol) or carboplatin (Paraplatin) plus docetaxel (Taxotere), gemcitabine (Gemzar), paclitaxel (Taxol and others), Vinorelbine (Navelbine and others) or pemetrexed (Alimta).
Although sometimes it has been seen that these treatments haven’t work or came back after sometime. To overcome these cases, doctors prescribed second course of drug treatment called as second-line chemotherapy.
Neoadjuvant Treatment can also be referred as Chemotherapy before other treatments. Receiving it at an early stage or before radiation or surgery help the lung cancer patients shrink the tumor making it comparable easier to taken out with surgery as well as increases the effects of radiation and diminishing the cancer cells as early as possible.
However, in case Chemotherapy does not work or tumor does not shrink, doctors have to cease the medication and proceed towards another treatment. Although it has been proved that lung cancer patients are able to cope with the side effects of Chemotherapy much more if it is given before surgery.
Many doctors in the world are giving Chemotherapy to their patients before surgery.
This can also be treated as one of the most exciting developments in lung cancer treatments. Targeted therapies are designed successfully in such a way that it can directly attack to its target or cancer cells by attaching to or blocking targets which are appearing on the surface of those cells.
When we talk about Chemotherapy drugs it cannot distinguish normal cells and cancer cells but target therapy has overcome such disadvantages.
Patients who are suffering from the lung cancer at the advanced stage with certain molecular biomarkers are treated by cancer specialist with the targeted drug either alone or in combination
A new treatment developed for treating certain types of lung cancer is referred as Immunotherapy. Unlike other cancer treatments causing various side effects Immunotherapy is generally tolerable.
There are endless diseases which are recovered by the immune system before we came to know about it. It constantly fight against infections, viruses, and growing cancer cells and also prevents our body get victim of these. Immunotherapy is designed in such a way that it uses our immune system for the treat the cancer.
Small Cell Lung Cancer
Chemotherapy and Radiation Therapy
Chemotherapy is regarded as an essence for the patients with small cell lung cancer at any stage. Stage of the cancer is necessary to determine the Radiation Treatment.
Doctors often gives Chemotherapy combining with Radiation therapy at the same time at the limited stage small cell lung cancer the most recommendable method.
Etoposide (Toposar or Vepesid) plus cisplatin (Platinol) is the most commonly used initial chemotherapy regimen.
However, patients suffering from small cell lung cancer at the extensive stage, Chemotherapy alone using the EP regimen is the most recomendable treatment.
Carboplatin (Paraplatin) plus irinotecan (Camptosar) is the another regimen that may be used with Chemotherapy.
Those patients whose cancer has spread over the brain radiation therapy of the brain is also used before or after Chemotherapy on some people.
Radiation Therapy of the Brain
Majority of the times it has seen that cancer has spread over the brain in the people suffering from the small cell lung cancer. After receiving response from the Chemotherapy patients are also given radiation therapy to prevent the cancer getting spread over the brain and this procedure is called as PCI (prophylactic cranial irradiation) considered as beneficial with both limited stage and extensive stage small cell lung cancer patients.
At the limited stage of small cell lung cancer which are often hard to discover can be treated from the surgery but no lymph node tumors may benefit from surgery, after which adjuvant chemotherapy is given.
We are providing this information to create an awareness among people regarding the Cancer Treatments in India. However, it is nowhere be treated as a substitute of specialist.
