What is larynx?

The area of the throat containing the vocal cords and used for breathing, swallowing, and talking. Also called voice box.

What is laryngeal cancer?

According to National Cancer Institute (NCI) definition laryngeal cancer is a cancer that forms in tissues of the larynx. Most laryngeal cancers are squamous cell carcinomas (cancer that begins in flat cells lining the larynx).

What are the treatment options for small cell lung cancer?

Treatment of small cell lung cancer depends on stage of cancer, patient’s age, fitness for treatment and other associated medical problem.

The role of surgery in small cell lung cancer is limited.

Limited stage small cell lung cancer can be cured with treatment, which usually involves combination of chemotherapy and radiotherapy. Patients usually need 4-6 cycles of chemotherapy every 3 weeks interval. Radiotherapy can be given in various schedules and forms. Recent advance in radiotherapy allows us to use Intensity modulated radiotherapy, which helps to precisely target the tumour while sparing surrounding normal tissue. 4D-CT scan is another advancement in lung cancer radiotherapy. It helps us to assess the movement of lung cancer precisely with breathing and help to precisely target the lung tumour.

Extensive stage small cell lung cancer is incurable and treatment option include chemotherapy or combination of chemotherapy+Immunotherapy.
About 50% of small cell lung cancer eventually relapse or spread to brain. Hence, as a preventative measures radiotherapy to brain often used after 4-6 cycles of chemotherapy; even when there is no cancer spread to the brain. 5-10 session of radiotherapy over 1 to 2 weeks, is often used for brain radiotherapy. This reduces the risk of cancer spread to brain and has also shown to improve survival in small cell lung cancer patients.

Palliative radiotherapy is sometimes used for symptom control like pain or bleeding etc.

November is National Lung Cancer Awareness month.

What are the stages of Non-small cell lung cancer?

Based on size or extent of tumour(T), spread to lymph nodes (N) and spread to distant organ (M) lung cancer can broadly be divided into four stages- stage I-IV.

What are the treatment options for different stages of non-small cell lung cancer?

Treatment of non-small cell lung cancer depends on Type of lung cancer, stage of cancer, patient’s age, fitness for treatment and other associated medical problem. The treatment option for non-small cell lung cancer include the following-

Stage I- Treatment option for stage I include surgery (Removal of one lobe of lung or entire lung with lymph node sampling), Stereotactic ablative radiotherapy or SBRT, Hypo fractionated radical radiotherapy. SBRT is a technique for delivering accurate and precise external beam radiotherapy to a lung tumour, using high doses per session, in 3–8 treatment fractions. It has been shown to be equally effective treatment option for stage I, as surgery.

Stage II- Treatment option for stage II include surgery (Removal of one lobe of lung or entire lung with lymph node resection), Stereotactic ablative radiotherapy, Hypo fractionated radical radiotherapy, Chemo radiotherapy, Chemo radiotherapy plus Immunotherapy.

Stage III- Chemoradiotherapy, Chemoradiotherapy plus Immunotherapy, Hypo fractionated radical radiotherapy, Chemotherapy followed by radiotherapy, Surgery (In very selected cases only).
Recent advance in radiotherapy allows us to use Intensity modulated radiotherapy, which helps to precisely target the tumour while sparing surrounding normal tissue. 4D-CT scan is another advancement in lung cancer radiotherapy. It helps us to assess the movement of lung cancer precisely with breathing and help to precisely target the lung tumour.

Stage IV- Chemotherapy, Immunotherapy, Chemo-Immunotherapy, Targeted therapy. Palliative radiotherapy is sometimes used for symptoms like chest pain, bleeding with cough etc.

Radiotherapy for lung cancer patients

In Lung cancer patients radiation therapy uses powerful, high-energy X-rays to kill cancer cells or keep them from growing.

When radiotherapy in needed in lung cancer?

1. Radiotherapy can be used to cure lung cancer for stage I-III lung cancer patients and some selected stage IV lung cancer patients with limited spread or oligo-metastatic disease.
2. It can be used to control the cancer or it’s symptoms in advanced stages of lung cancer.
3. Sometimes it is used before surgery for lung cancer to shrink the tumour down.
4. It is sometimes indicated after surgery to reduce the risk of recurrence.
5. In small cell lung cancer roughly about 50% patients eventually develop cancer spread to the brain. So sometimes preventive radiotherapy is used to treat the brain to prevent the cancer spread to the brain in small cell lung cancer patients.

What are the different types of lung cancer radiation?

There are many ways to treat lung cancer patients with radiation. We choose the modalities depending on patient’s tumour size, location, stage and various other factors. The main goal is twofold: to eliminate tumor cells and to prevent the side effects of treatment by keeping the healthy cells around the tumor safe. These are the different types of Radiation used in lung cancer.

1. 3D-Conformal Radiotherapy
2. Intensity Modulated Radiotherapy or IMRT
3. Image Guided Radiotherapy or IGRT
4. Adaptive Radiotherapy
5. Stereotactic Body Radiotherapy (SBRT)
6. Proton beam therapy
7. Chemo-Radiotherapy
8. Palliative Radiotherapy
9. Brachytherapy

Cancer cure is possible with Image Guided Radiation Therapy (IGRT) : Precise, Efficient, Safe

What is IGRT?

Image-guided radiation therapy, or IGRT, is a type of cancer treatment that uses imaging technologies such as PET, MRI, and CT or 4D-CT to more accurately and safely deliver radiation to cancer cells. The machines that are used to deliver the radiation, called linear accelerators, are equipped with the imaging equipment so that doctors can confirm exactly where the tumor is in the body before and during treatments.

What are the advantages of IGRT?

The main advantage of IGRT is that it is very precise. It makes it possible to
• use higher doses of radiation to kill the cancer
• avoid harm to healthy tissue
• keep radiation side effects to a minimum

October is National Breast Cancer Awareness Month.

Metastatic breast cancer: Is it the end?

What is metastatic breast cancer?

Metastatic breast cancer is a stage of cancer when cancer cells have spread from the breast to other parts of the body. It is also called advanced breast cancer or stage IV breast cancer.

What investigations are done before starting treatment in such patients?

• History taking including family history of any cancer
• Clinical examination
• Baseline blood tests
• Biopsy
• Estrogen receptor, Progesterone receptor, HER2Neu receptor and Ki-67% on biopsy sample
• PDL1 status on biopsy sample
• Some times we check for mutations like PIK3CA, BRCA 1& BRCA 2.
• CT scan of chest, abdomen, Pelvis
• Whole Body PET-CT scan
• MRI brain when suspecting cancer spread to brain
• 2D-Echocardiography before using particular targeted therapy

What is the prognosis of metastatic breast cancer?

Metastatic breast cancer is usually incurable. The aim of treatment at this stage is to try to control the cancer, try to control the symptoms from cancer, and try to improve the quality and quantity of life. A limited subgroup of patient called Oligo metastatic disease (Small or limited spread to other organ) can be treated with curative intent.
