In two patients with renal cell carcinoma, late metastases to the remaining kidney were found. The metastases were histologically identical to the primary tumor, and more than one nodule recurred in both cases. Advanced surgical techniques allowing removal of metastases from the sole kidney make diagnosis of these lesions clinically important.

We report two cases in which partial resection and reconstruction of the superior vena cava (SVC) were performed with the use of a temporary SVC-right atrial internal bypass for complete resection of carcinoma of the right lung. In the first case, the SVC was invaded by the primary tumor itself, arising in the anterior segment of the right upper lobe. In the second case a metastasized tracheobronchial lymph node had invaded the SVC. In both cases, partial resection of SVC was performed safely with the internal bypass technique.

The records of 112 patients treated at the Ochsner Foundation Hospital with the diagnosis of bronchogenic carcinoma were reviewed. A new concept for defining the location of central versus peripheral tumors is presented. Criteria important in selection of patients for whom mediastinoscopy is likely to be helpful are cell type, location (peripheral versus central), and radiographic evidence of mediastinal metastasis. The size of the tumor is not a useful criterion except possibly for squamous cell lesions. A high incidence of mediastinal metasis was found associated with central tumors (63 to 100 per cent) of all cell types and with peripheral lesions (63 per cent) of undifferentiated cell types. A relatively low incidence of mediastinal metasis was associated with peripheral asenocarcinomas or squamous cell tumors. We would, therefore, recommend mediastinoscopy for all patients with central lesions and those patients with peripheral lesions of an undifferentiated cell type. When correlated with radiographic findings, only 4.6 per cent of peripheral carcinomas of a differentiated cell type with a radiographically normal mediastinum were found to produce mediastinal metastases, and mediastinoscopy is not recommended. In patients with peripheral tumors of indeterminate cell type, a decision for mediastinoscopy may be influenced by other factors such as the operative risk of a thoracotomy and location of the primary tumor within the lung.

A multimodal therapy concept for small-cell lung cancer, which for patients with established pretherapeutic homolateral lymph-node metastases (N2) prescribes induction chemotherapy with subsequent resection as well as supplemental chemo- and radiotherapy, provided the opportunity to evaluate histologically the radiological diagnoses "complete remission" and "partial remission" using resection specimens. In 17 patients a 75% to 100% reduction in tumor size was achieved according to radiological diagnosis. Predictions of "no evidence of disease" or "evidence of disease" were only correct in ten cases. In the remaining seven cases, histology showed the radiological findings to be incorrect. This gives a 77% sensitivity for radiological diagnosis with no specificity. Moreover, differentiation between therapy effect on the primary tumor and on the N2 metastases gives similar results: sensitivity 64% and 67% respectively, specificity 33% and 25% respectively. It is concluded that, particularly after the tumor responds well to therapy, radiological techniques are unsuitable for establishing a diagnosis of "no evidence of disease" or "evidence of disease" in small-cell lung cancer. This is because on the one hand the radiological methods available do not permit clear differentiation between vital tumor tissue and necrosis or fibrosis, while on the other hand groups of vital tumor cells beyond the resolution power of X-ray technology will escape detection.

The ploidy status of the deoxyribonucleic acid of a malignant lung tumor provides additional information besides histologic grading and tumor staging according to lymph node infiltration and tumor metastasis. Ninety-nine surgical specimens from patients with non-small-cell lung carcinoma were investigated by flow cytometry. Deoxyribonucleic acid aneuploidy was found in 48% of the primary tumors. Patients with deoxyribonucleic acid-euploid tumors showed better survival (p < 0.01) than those with deoxyribonucleic acid-aneuploid carcinomas independent of tumor stage. Deoxyribonucleic acid ploidy status of the primary tumor was compared with that of N2 lymph node metastases in 29 cases. Seven samples showed a change from deoxyribonucleic acid aneuploidy in the primary tumor to deoxyribonucleic acid euploidy in the lymph node metastases. Survival was significantly better for patients with euploid primary tumors and lymph node metastases, followed by patients with deoxyribonucleic acid-aneuploid primary tumors and euploid lymph node metastases. Survival was poorest in patients with deoxyribonucleic acid-aneuploid primary tumors and lymph node metastases. It was observed that only the simultaneous determination of deoxyribonucleic acid ploidy of primary tumors and lymph node metastases permits accurate prognostic evaluation in case of lymph node infiltration.

During the years 1960 to 1989, 145 patients underwent sleeve lobectomy or sleeve resection of a main bronchus. Follow-up was complete except for one patient, who was no longer available for follow-up 4 years after operation. Eleven patients (7.6%) had a second primary cancer in the lung; 10 of these patients (90.9%) were men. Mean age at sleeve operation was 61.2 +/- 11.6 years. Mean interval between sleeve operation and development of second primary cancer was 53.8 months (range, 6 to 197 months). All second primary cancers occurred on the contralateral side. In five cases there was squamous cell carcinoma, in two there was adenocarcinoma, in one there was adenosquamous carcinoma, in two there was small cell carcinoma, and in one patient no definite histologic type could be established. Five patients had different histologic type from the initial, resected primary tumor. Seven patients (64%) were operated on: five underwent lobectomy and two underwent segmentectomy. In one patient the tumor was judged to be unresectable. Chemotherapy was given to the two patients with small cell carcinoma and radiotherapy was given to one patient with bone metastases. Follow-up was complete for these 11 patients. Data were calculated from detection of second primary cancer. There was one postoperative death from myocardial infarction. Eight other patients died during follow-up: five died of recurrent tumor or metastases, two died of acute cardiac failure, and one died of a perforated ulcer. The 1- and 4-year actuarial survivals were 41% and 30%, respectively. For the patients operated on, 1- and 4-year survivals were 57% and 43%, respectively. There were no survivors at 5 years. Sleeve resection is a valuable method of preserving functional lung tissue. It offers a chance of subsequent resection in patients who have second primary cancer, with acceptable results.

Between 1970 and 1989, mediastinoscopy and thoracotomy were performed on 619 patients admitted to our clinic with lung cancer. When mediastinoscopy was analyzed by lymph node location, the highest sensitivity (95.7%) was for the left paratracheal nodes and the lowest (64.0%) was for nodes at the bifurcation (p < 0.01). The 5-year survivals according to the results of mediastinoscopy were 47% for negative results, 14% for false-negative results, and 6% for positive results. The 5-year survival rate however, was significantly higher (28%) in patients (n = 13) with positive mediastinoscopic findings who underwent complete resection of the primary tumor and all involved nodes than in patients (n = 78) who underwent incomplete resection (p < 0.01). These data support our opinion that patients with positive mediastinoscopic results should not always be excluded from treatment by thoracotomy. The role of mediastinoscopy is not to select patients for thoracotomy but to evaluate lung cancer at the pretreatment stage.

There is an increasing demand for accurate preoperative and intraoperative staging of bronchial carcinoma with respect to neoadjuvant therapy protocols and parenchyma-sparing operations. This study prospectively evaluated accuracy of computed tomographic scan and surgical assessment for staging of bronchial carcinoma in 108 consecutive patients. The stage of the primary tumor (T stage) was correctly determined in 85% of the patients, and surgical evaluation correctly determined the T stage in 92%. Invasion of major mediastinal structures posed a major problem for computed tomographic scan. On a node-by-node basis, computed tomographic scan predicted involvement of lymph nodes in 81% (sensitivity 29%, specificity 93%, positive predictive value 49%, negative predictive value 85%). The surgeon correctly determined the lymph node status in 69% of lymph nodes (sensitivity 90%, specificity 63%, positive predictive value 39%, negative predictive value 96%). On a patient-by-patient basis, computed tomographic scan correctly predicted the nodal status in 58% of patients. Accuracy of computed tomographic scan and surgical assessment in determination of the lymph node status strongly depended on tumor type and lymph node region (hilar or mediastinal region) studied. This was partly due to the fact that adenocarcinomas exhibited a high proportion of tumor-positive normal-sized lymph nodes, whereas squamous cell carcinomas showed a high proportion of enlarged tumor-free lymph nodes. In conclusion, computed tomographic scan and surgical assessment are sufficiently accurate for determination of the tumor stage but are insufficient in determining the nodal status.

Second operations were performed in 1961-1990 on 23 patients with non-small cell bronchogenic carcinoma, constituting 2.5% of 906 who had undergone pulmonary resection for such tumor and 3.6% of the 641 with apparently curative surgery. The second operation was performed for recurrent tumor in 15 cases and for second primary tumor in eight. Five-year survival after the first operation was 30% in the former group and 88% in the latter (significant difference). Among the total 23 patients, this survival rate was 51%. The study indicates that an aggressive attitude to second surgical intervention is warranted. For early detection of second lesions, follow-up at maximally 6-month intervals should be continued for more than 5 years after the first operation.

Tumor involvement of the carotid artery with head and neck cancers may be present either simultaneously with the primary lesion or more often appears at a later date following resection of the primary tumor. Management of the secondary tumor consists of its resection together with the involved carotid artery with or without carotid artery reconstruction. The Authors are convinced that the best chance for cure of patients with advanced head and neck squamous cell cancers involving the carotid artery is radical extirpation with ablative surgery in the form of en block resection of the primary lesion, the secondary tumor, and the involved carotid artery followed by immediate revascularization. This bold approach was carried out in two male patients, 48 and 61 years of age, followed by chemotherapy and radiation therapy in one and radiation therapy alone in the other, with excellent results. Dermal grafts were placed over the entire length of the arterialized veins to protect them from radiation injury. Based on this limited experience and excellent results, we recommend this one-stage surgical ablative procedure in well selected patients. However, cooperation between the ENT and vascular surgeons, strict adherence to the principles and techniques of vascular surgery, and coverage of the arterialized vein with a dermal graft is absolutely essential.
