“…Thus, CT will continue to be the most satisfactory method for preoperative staging oflung cancer. Some authors consider staging unnecessary in patients with peripheral tumour (3,14). In the present material 33 tumours were peripheral, and 3 (9%) of these were not resectable due to the presence of mediastinal metastases.…”

In order to assess the potential of computed tomography (CT) of the mediastinum and mediastinoscopy in the staging of lung cancer, 125 patients were examined. Of these, 104 underwent thoracotomy, at which there was no evidence of mediastinal tumour involvement in 79 while 25 patients had signs of tumour spread. The sensitivity and specificity of CT were 87.0 per cent and 95.8 per cent, respectively, in the detection of direct tumour extension with a mediastinal mass. When lymph node enlargement was the sole finding, CT did not provide any differentiation between benign and malignant lymphadenopathy. The mediastinal involvement was inaccessible on mediastinoscopy in 18 cases (72%). Despite the surperior sensitivity of CT it was often difficult to determine whether direct tumour infiltratin of mediastinal structures had occurred. It was concluded that CT is necessary for screening the entire mediastinum and, when it reveals no evidence of mediastinal tumour spread, mediastinoscopy will yield no further information. Mediastinoscopy will help to correctly identify accessible mediastinal lymph node involvement of the superior mediastinum and to define the mediastinal tumour invasion in doubtful cases.

This review has summarized the status of organ site cancer imaging as applied to tumor detection, staging, and posttreatment follow-up. More general questions which have not been addressed include those related to the following: (1) the problem of providing more adequate training of radiologists in the specific challenge of cancer imaging; (2) how to increase the awareness of oncologists as to the specific indications and applications of tumor imaging procedures and enhance joint communication between radiologists and clinicians in the planning of the imaging procedures; and (3) how to stimulate the radiology and oncology communities to establish imaging standards and recommended procedures for specific tumor imaging challenges. Hopefully, an appreciation of the complex challenge of cancer imaging will result from these and subsequent discussions.
