Most of the patients of SCLC are not surgical candidates, due to advanced stage at presentation hence only viable options are chemotherapy and radiotherapy. Long-term survival in SCLC is extremely rare due to relapses and comorbidities. Ten-year survival has never been reported in cases with extensive disease at presentation and history of relapses. Here we are describing a case of extensive disease SCLC who has survived multiple relapses and has received five lines of systemic therapy apart from radiation and palliative care. This case emphasises on the need of active and strict disease surveillance at each follow-up.<\/jats:p>","DOI":"10.1136\/bcr-2019-232607","type":"journal-article","created":{"date-parts":[[2020,2,28]],"date-time":"2020-02-28T14:25:10Z","timestamp":1582899910000},"page":"e232607","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Extensive-disease
