For some years now, bronchial plastic surgery has given surgeons the possibility of radically treating patients with carcinoma of the lung that otherwise could not undergo surgery because of insufficient cardiorespiratory functional capacity as well as the peculiar endoluminal location of the neoplastic lesion. These methods, however, often show problems of dysventilation and bronchial engorgement that--in our opinion--are attributable to vagal denervation following surgical maneuvers. Hence, our study aimed at reproducing experimental surgical models of sleeve-resection in order to examine these problems. Consequently, we operated on 10 pigs divided into two groups (A end B) of 5 animals each; we performed surgery on the first five animals without removing vagal fibres, whereas in the other we have coupled sleeve-resection with vagal denervation of the residual parenchyma. All the animals have been followed-up by means of X-ray examination, bronchoscopy and direct stimulation of the cough-producing reflex (by means of the catheter positioned intraoperatively below the anastomosis). The data obtained confirm our assumptions, given that in "denervated animals" we observed a large engorgement of the respiratory tract with late onset of cough-producing reflex, while in the control group (without removal of vagal fibres) no bronchoplegic or alteration of the muco-ciliary clearance was found post-operatively. All animals, for the entire period of experimentation, received care in accordance with the "Principles of Laboratory Animal Care" formulated by the US National Society of Medical Research and the "Guide for the Care and Use of Laboratory Animals" (NIH Publication N. 80-23, revised in 1980).

An autopsy case of malignant fibrous histiocytoma (MFH) with widespread metastases and lung carcinoma in a 64-year-old Japanese woman is reported. The initial signs were cough and sputum, followed by hemosputum. A chest X-ray photo showed a right pleural tumor, which could not be identified from a biopsy specimen, but was identified as MFH by light and electron microscopic studies on biopsy specimens of tongue tumors. Autopsy examination revealed metastases of the MFH to the brain, lung, liver, kidney, adrenal, pancreas, retroperitoneum, and some bones, and pulmonary adenocarcinoma.

Scalene node biopsy (SNB) has been performed in patients with lung cancer at the Saint Francis Hospital and Medical Center if any of the following criteria has been present: (1) potentially resectable central lesion by chest radiograph, or (2) significant cardiac or pulmonary dysfunction, thereby placing the patient at increased risk for thoracotomy, or (3) a diagnosis of adenocarcinoma prior to SNB. Within these guidelines, a retrospective study was undertaken to determine the benefit of routine SNB in the absence of clinically palpable scalene nodes. In a 2-year period beginning April 1981, 56 patients (37 males) presented with radiographic evidence of lung carcinoma without clinical evidence of scalene adenopathy. Approximately half of the lesions were of a central position. While the majority had symptoms of cough, hemoptysis, or chest pain, the primary lung lesion was identified on routine chest radiograph in 15 (27%). In only three was there no history of smoking, the remainder having at least a 20-pack-year history of cigarette use. Following a routine evaluation, 57 SNBs were performed alone or in concert with other surgical procedures (mediastinoscopy, bronchoscopy). Of these, only two (3.5%) were diagnostic and indicative of unresectable disease. While in one patient no additional procedure was performed, a simultaneous Chamberlain procedure in the other confirmed that the patient was unresectable for cure. In the remaining patients, tissue diagnosis of cancer was obtained through other maneuvers. Because of the low probability that SNB in the absence of clinically palpable nodes altered the management of lung cancer, we do not believe it to be of benefit in the diagnosis or staging of this disease.

The prevalence of atypical cytology has been determined in relation to age, smoking and asbestos exposure for male workers employed in 3 mines in the Province of Quebec. Overall participation was 71%. Out of 867 participating workers, 626 (72%) presented a deep cough specimen within normal limits, 74 (8.5%) a specimen with mild atypical metaplasia and 10 (1.2%) a specimen with moderate atypical metaplasia. Four lung carcinoma were identified. Five percent of the workers initially interviewed did not return their specimen and 12.7% had unsatisfactory test results. Proportions of cellular atypia increased with age and asbestos exposure. Using logistic regression analysis, estimated probabilities of abnormal cytology for workers aged 25 years when started mining increased with both years of asbestos exposure and exposure index measured in fibres per cubic centimeter.

Some factors influencing the detection of malignant cells in sputum samples were evaluated in 449 consecutive cases of primary lung carcinoma seen between 1959 and 1974. Diagnostic accuracy increased during the years under study; the reasons are discussed. The overall accuracy was 82.8%. Detection of malignant cells was 85% for small-cell carcinoma, squamous-cell carcinoma and large-cell carcinoma, 75% for adenocarcinoma, bronchioloalveolar carcinoma and adenosquamous carcinoma and 64% for the uncommon tumors. Accuracy was 87% for central tumors and 42% for peripheral lesions. Tumors less than 2 cm in diameter yielded only 39% accuracy as compared to 90% for larger tumors. The specificity of diagnosis of cell type in those specimens with malignant cells was 95% for small-cell carcinoma and squamous-cell carcinoma, more than 80% for adenocarcinoma and large-cell carcinoma, 65% for bronchioloalveolar-cell carcinoma and adenosquamous carcinoma and less than 30% for the uncommon tumors. Diagnostic accuracy was optimal in those cases with three or more sputum samples: 83% for those with three samples and 90% for those with five or more samples per case. The use of both sputum and bronchial specimens was complementary and increased the accuracy further. Reasons for unsatisfactory specimens included no deep cough, limited cellular material, excessive blood or leukocytes and drying artifacts; the first two were the most common causes.

A total of 458 eligible patients, from 21 centres, with microscopically confirmed SCLC were allocated at random to three chemotherapy regimens, each given at 3-week intervals. In two regimens, etoposide, cyclophosphamide, methotrexate and vincristine were given for a total of either three courses (ECMV3) or six courses (ECMV6). In the third regimen, etoposide and ifosfamide were given for six courses (E16). Patients with limited disease also received radiotherapy to the primary site after the third course of chemotherapy in all three groups. As reported by clinicians, 59% of the ECMV3, 67% of the ECMV6 and 63% of the EI6 patients experienced moderate or severe adverse reactions to their chemotherapy. The major symptoms of disease, cough, haemoptysis, chest pain, anorexia, and dysphagia, were palliated in 63% or more of patients and the median duration of palliation was 63% or more of survival, the results being similar in the three groups. Among patients with poor overall condition, physical activity and breathlessness on admission, the proportions who improved were higher in the EI6 group but the differences were small. In all three groups, levels of anxiety fell substantially during treatment. Levels of depression were lower and showed little change. As assessed by patients using a daily diary card, the patterns of nausea, vomiting, activity and mood, associated with courses of chemotherapy were very similar in the three groups. In the EI6 group there was less dysphagia and better overall condition between courses, but these advantages need to be weighed against the inconvenience of the 24-h infusions required, compared with the 30-min infusions of the other two regimens. As reported in the companion paper (MRC Lung Cancer Working Party, 1993a) there was no statistically significant survival advantage to any of the three regimens, although the results do not exclude the possibility of a minor survival advantage with the two six-course regimens. In conclusion, there was no major clinical gain from continuing chemotherapy beyond three courses or from using the ifosfamide regimen.

The ten most frequently reported pretreatment symptoms on the Rotterdam Symptom Checklist, which was completed by more than 650 patients entering two MRC Lung Cancer Working Party multicentre randomised trials, included general symptoms (tiredness, lack of appetite) and psychological distress (worry, anxiety) in addition to disease-related chest symptoms (cough, shortness of breath). Although the number and severity of symptoms increased with worsening performance status, the commonest symptoms were found to be virtually the same for patients with small-cell lung cancer (SCLC) and non-small-cell lung cancer (NSCLC), and for different grades of performance status. Women with NSCLC reported more psychological symptoms than males, but this difference was much less evident in patients with SCLC. Thus, in order to assess fully the benefit of palliative treatments in patients with lung cancer, account must be taken of all symptoms at presentation, in addition to the traditionally recognised chest symptoms.

Forty cases of small cell lung carcinoma (SCLC) treated with surgical and chemotherapeutic combined therapy were reported. There were 28 males and 12 females in the group, most with history of more than 2 months, ranging in age of 27-66 years old. Cough, bloody sputum, low fever and chest distress are the main clinical manifestation. The small cell undifferentiated carcinoma was confirmed by fiberbronchoscope examination and pathology in all patients. Single lobectomy was performed in 20 cases, lobectomy of the upper and middle lobe in 9 cases, (sleeve resection of the lobarbronchus in 3 cases), and total pneumonectomy in 7 cases. Two cases were of stage I, 18 were of stage II, and 20 were of stage IIIa. Twelve patients received chemotherapy after operation, and 28 patients underwent the "chemotherapy-operation-chemotherapy" treatment model. Adriamycin (or CDDP), cytoxan, vincristin, and dexomathasone were used for the chemotherapy procedure. The 1, 3, 5-year survival rate of chemotherapy after operation and chemotherapy-operation-chemotherapy group were 70%, 45%, 30.5% and 54%, 30% and 22%, respectively. It is demonstrated that the long-term survival rate could be elevated in SCLC patients treated with chemotherapy after surgical operation, and the chance of operation also could be elevated by preoperative chemotherapy. The resection rate was 93% in the preoperative chemotherapy group.

From February 1965 to April 1993, 88 patients with middle lobe carcinoma of the lung were treated surgically. It constituted 7.7% of the total patients of operated lung cancer in our hospital. Clinical symptoms were mainly fever, cough, bloody-sputum and chest pain. 84 of 88 patients were treated by wedge resection, lobectomy and pneumonectomy. Exploration was preformed in 4 patients. The 1, 3, 5 and 10-year survival rates of the 78 patients followed up were 87.18%, 43.08%, 38.18% and 24.13% respectively. It related to four clinical features of middle lobe cancer of the lung were treated surgically is discussed.

Sputum cytology was performed to rule out primary lung carcinoma in a patient with a cough of recent onset, an infiltrate on chest roentgenography and a history of bladder and prostate carcinoma. The cytology was interpreted correctly as metastatic transitional cell carcinoma. Review of the cytology by other pathologists without the benefit of the previous history or histologic material resulted in interpretations of reactive/metaplastic tissue. A morphometric comparison of nuclear parameters between the cells in the sputum and the squamous metaplastic cells seen in the sputum of a patient with viral pneumonia from our archives was performed. Evaluation of the current sputum cytology without the benefit of clinical information or additional studies may have led to a false-negative diagnosis.
