₹ 10500


Fluorescence In Situ Hybridization, commonly known as FISH, for ROS-1 is a diagnostic test specifically used in cases of Non-Small Cell Lung Cancer (NSCLC). Lung cancer is a type of cancer that starts in the lungs and can spread to other parts of the body. NSCLC is the most common type of lung cancer. The ROS-1 gene plays an important role in cell growth and division. In some cases of NSCLC, there is a rearrangement of the ROS-1 gene, which can contribute to the development of cancer. Detecting ROS-1 rearrangements helps in identifying patients who may benefit from targeted therapies, which are specifically directed against the ROS-1 protein.

The FISH test for ROS-1 involves the use of fluorescent probes to visualize the ROS-1 gene in the cancer cells. By using a special microscope, the doctor can see whether or not there is a rearrangement in the ROS-1 gene, which would be indicative of the presence of ROS-1 positive NSCLC.

What is the importance of getting the FISH for ROS-1 test done?

Detecting ROS-1 rearrangements is crucial for the management of NSCLC. Patients with ROS-1 positive NSCLC may benefit from targeted therapies, which can be more effective and have fewer side effects compared to conventional chemotherapy.

Is fasting required for this test?

No, fasting is not required for the FISH for ROS-1 test. The test is performed on tissue samples, usually obtained through a biopsy of the lung tumor.

Is there any specific preparation needed for the test?

There is no specific preparation needed for the patient as this test is performed on tissue samples. However, it is essential that the biopsy sample is handled and processed correctly by the laboratory to ensure accurate results.

When should I get this test done?

Your doctor may recommend this test if you have been diagnosed with NSCLC and they are considering targeted therapies as a treatment option. The test is used to identify if the ROS-1 gene is rearranged, which is necessary information for determining the best treatment strategy.

What information does the test provide?

The FISH for ROS-1 test provides information about the presence or absence of ROS-1 gene rearrangements in lung cancer cells. This information is critical for determining if a patient with NSCLC is likely to benefit from targeted therapies aimed at ROS-1.

How often should this test be done?

This test is usually performed once, at the time of diagnosis or when considering treatment options for NSCLC.

What are the normal values for this test?

In normal cells, the ROS-1 gene is not rearranged. In ROS-1 positive NSCLC, a rearrangement of the ROS-1 gene is present.

What precautions should be taken?

As a patient, there are no specific precautions you need to take. However, it is crucial for the tissue sample to be handled properly to ensure the test’s accuracy.

What factors can affect the levels of ROS-1?

The rearrangement of the ROS-1 gene is a genetic change that occurs in the tumor cells and is not affected by lifestyle or environmental factors.

Which doctor should I consult if I have abnormal results?

If the FISH for ROS-1 test indicates that you have a ROS-1 rearrangement, you should consult an oncologist, who is a doctor specializing in cancer treatment. Your oncologist will discuss the treatment options, including targeted therapies, based on the test results.

Are there any side effects or risks associated with this test?

There are no side effects or risks associated with the FISH test itself, but there may be risks associated with the biopsy procedure used to obtain the tissue sample.

How is the tissue sample obtained for this test?

The tissue sample for the FISH for ROS-1 test is typically obtained through a biopsy, which involves removing a small piece of the lung tumor for examination.

Can this test be used for other types of cancer?

FISH for ROS-1 is primarily used for NSCLC. However, ROS-1 rearrangements have been observed in other cancers, and the test may be used in specific cases based on the doctor's discretion.

Can the test be wrong?

As with any diagnostic test, there is always a possibility of false positives or false negatives. However, FISH is a highly accurate and sensitive method. If there is any doubt about the results, the test may be repeated or supplemented with other diagnostic tests.

What are the treatment options if I test positive for ROS-1 rearrangement?

If you test positive for ROS-1 rearrangement in NSCLC, your doctor may recommend targeted therapies that specifically target the ROS-1 protein. These medications can help to shrink or slow the growth of the tumor.

The FISH for ROS-1 test is an integral part of managing Non-Small Cell Lung Cancer. It helps in identifying the patients who may benefit from targeted therapies. There is no specific preparation required for the test, and it's usually performed once at the time of diagnosis. Consultation with an oncologist is essential for discussing the treatment options based on the results of the test.
