Diagnosed With Small Cell Carcinoma. Reoccured After Chemo. On Topectan. Oxygen Rate Dropped. Has Tumour In Head. Advise?
Thanks for your query.
Your brother has got small cell carcinoma with a stage of extensive disease. You also told that First chemotherapy failed and is on second line drug topotecan.
Decreased oxygen saturation can be due to lung infection owing to decreased immunity due to malignancy as well as by chemotherapy.
Metastasis can't be predictable. After adrenal and pancreas may be to bone, brain. or there is possibility that it has already metastasized to brain.
Paraneoplastic syndrome do not present like hypoxemia. It's just part and parcel of primary disease.
I wish if you could go for fresh complete blood count and chest x-ray to see for the development of infection. Accordingly sputum for gram's staining and culture is advised. If chest xray shows a new consolidation or ground glass opacity, a trial of antibiotic can be given. A short course of steroid under antibiotic cover may help to combat the acute situation. Continue the oxygen therapy.
I am sorry but you must be knowing the prognosis.
Best wishes
Thanks for follow up.
