Squamous cell carcinoma lung with skeletal muscle involvement, eight year study of a tertiary care hospital in Kashmir

Aims: Lung cancer is the most common malignancy throughout the world. Non-small cell lung cancer (NSCLC) is most common type, and squamous cell type is most common in India. Mostly patients present with chest related symptoms and signs. Isolated skeletal muscle metastasis is rarely seen. Aim was to see muscle metastasis and its prognosis. Methods: We are presenting our data of eight years about this common malignancy with relation to muscle metastasis, either alone or with other system metastasis. Results: Muscle metastasis is seen 1.5% of patients, with M: F OF 8:1. Over all median survival was 15 months and progression free survival was 12 months. Conclusion: One peculiarity seen was isolated skeletal muscle metastasis with no pulmonary system and severe paraneoplastic hypercalcemia. Local therapy may be having an impact on overall survival in metachronous muscle involvement.
