Squamous Cell Carcinoma Lung with Skeletal Muscle Involvement: A 8-year Study of a Tertiary Care Hospital in Kashmir

Aims Lung cancer is the most common malignancy throughout the world. Nonsmall cell lung cancer (NSCLC) is the 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 (ISMM) is rarely seen. The aim was to see muscle metastasis and its prognosis. Materials and Methods We are presenting our data of 8 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 male: female of 8:1. Overall median survival was 15 months and progression-free survival was 12 months. Conclusion One peculiarity seen was ISMM with no pulmonary system and severe paraneoplastic hypercalcemia. Local therapy may be having an impact on overall survival in metachronous muscle involvement.
