Does the surgical trauma of "exploratory thoracotomy" affect survival of patients with bronchogenic carcinoma?
A retrospective review was carried out to assess the possible adverse immunosuppressive effect of exploratory thoracotomy on the survival of patients with non-small cell carcinoma of the lung with N2 nodal metastases. Between 1960 and 1982, 48 patients with non-small cell bronchogenic carcinoma underwent exploratory thoracotomy; lung resection was not done because mediastinal lymph nodes were involved. The survival of these patients was compared with that of 64 patients in whom N2 disease was established by mediastinoscopy alone and who did not undergo thoracotomy. There were no significant differences with respect to age, sex, tumour type and adjunctive radiotherapy. There were slightly more T4 tumours in the thoracotomy group (50% versus 30%). The hospital stay was longer in the thoracotomy group (2.3 +/- 1.1 versus 1.5 +/- 0.9 months [mean +/- SD]). However, follow-up studies showed that, although these patients had a more traumatic procedure, the actuarial survival curves for the two groups were virtually identical, and the 12-month survival rates were less than 20% for both groups. The median survival was 6.0 months for the thoracotomy group and 7.0 months for the mediastinoscopy group. These findings failed to demonstrate an adverse immunosuppressive effect of thoracotomy on lung cancer patients.
