Regression of pulmonary metastatic disease associated with intralesional bcg therapy of intracutaneous melanoma metastases

Abstract: A 77-year-old white man with 64 intracutaneous melanoma metastases and a pulmonary metastatic deposit was treated with immunotherapy. Over an 8-month period, 17 intracutaneous lesions were inoculated with BCG. All 17 injected lesions and all 47 uninjected intracutaneous lesions resolved; no new nodules appeared and the pulmonary metastasis regressed (greater than 50%). This is the first documented case of a pulmonary metastatic focus responding to intralesional BCG therapy of intracutaneous metastases.

“…Intralesional therapy for metastases from melanoma was first systematically evaluated in the 1970s with Bacillus Calmette Guerin (BCG) which was first reported to produce remission in injected lesions and also distant metastases [64]. An immune-mediated systemic response was hypothesized to be the basis behind the occasional systemic response, but randomized trials of BCG have failed to confirm a significant clinical benefit [65].…”

“…17,18 Similar frequencies of response in injected lesions were demonstrated and regression of even distant metastatic disease was observed in the setting of injection of superficial metastases. 19 It is fascinating, in the era of ipilimumab, to note that the regression of a lung metastasis after BCG injection into skin metastases was observed after initial progression of the distant site. The time course of this delayed response parallels almost exactly that observed in delayed ipilimumab responses that are seen frequently with current checkpoint blockade.…”
