Spontaneous regression of bronchogenic carcinoma

Partial regression in primary carcinoma of the lung: does it occur?

“…Only six cases reported in the English literature this century [15][16][17][18][19][20] fulfil Everson and Cole's criteria 1 for true complete spontaneous regression. In four of these cases the immune system is directly implicated as the probable mediator of regression, with reports of continued immunity against histologically similar tumours, 17 concurrent infection and raised body temperature, 19 evidence of increased host immunity on biopsy 18 and association of regression of small cell lung cancer with paraneoplastic neuropathy, 20 believed to be antibody mediated. 21 There are no reports of partial regression of lung cancer.…”
