Rectal Carcinoma with Lung Metastasis

Rectal Carcinoma with Lung Metastasis

Case History
A 77-year-old male was presented to Apollo Speciality Cancer Hospital reporting rectal carcinoma that was diagnosed in the year 2006. The patient was then undergone surgery (anterio perineal resection), radiation therapy and chemotherapy. The patient was clinically stable until the year 2009. In the year 2009, he developed repeated episodes of cough and pain on the right side of the chest. Owing to these complaints, the patient was evaluated by performing whole body PET scan. The scan revealed increased metabolic activity in lower lobe of the right lung and posterior basal segment pleural base mass. No other sight in the body showed activity (disease) in the PET scan. Biopsy from the lung mass was suggestive of metastatic adenocarcinoma.

The patient was diagnosed with solitary lung metastasis with controlled primary site disease and was planned to treat with radical intent using CyberKnife®. He was treated with 45Gy in five fractions in 1 week through CyberKnife® radiosurgery. The patient tolerated the radiosurgery well.

A follow-up CT scan was performed at 6-month post-CyberKnife®. The scan revealed a significant reduction in the lung mass.

Discussion
Generally, patients having solitary (single) or ‘oligo metastasis’ (<3 metastasis) with otherwise good general health and controlled primary disease are treated with curative intent. Surgery (metastectomy) is the preferred treatment. However, surgery may not be possible in a large
number of patients because of their medical condition or age. Therefore, these patients can be treated with radiosurgery using CyberKnife®
