17 cases with bronchial carcinoid were reported. 16 cases of them were proved pathologically after pulmonary resection, and the remaining one was confirmed histopathologically through bronchoscopic biopsy. 64.7% was under 40 years of age. The main clinical manifestations were cough, hemoptysis, fever and repeated pneumonitis. In one patient, the carcinoid was associated with Cushing's syndrome. Chest roentgenograms showed lesions centrally located in 12 cases, and peripherally located in 5 cases. Histological examination revealed 15 typical and 2 atypical carcinoid tumors. This disease was usually misdiagnosed as lung cancer, tuberculoma and benign tumors. Chest X-ray examination and fiberoptic bronchoscopic biopsy are helpful to the diagnosis of the disease. Pulmonary resection was performed in 16 cases. Two patients had hilar lymph node metastases, one of them had also involvement of pericardium. There was no operative mortality. In the follow-up study, the disease-free actuarial survival following pulmonary resection was 92.9% at 5 years. 2 patients died. One died of respiratory failure 4 months after pneumonectomy, the other died of pericardium involvement of carcinoid 8 months after operation. Resection is the only effective treatment for bronchial carcinoid.

Some lung cancer patients after surgical treatment die as a result of pneumonia or cardiac failure without recurrence of lung cancer months or years after surgery because many such patients are aged or have decreased lung function. Surgical treatment may be partly to blame for these deaths. In this article, to evaluate the contribution of surgical treatment to deaths resulting from other disease, we calculate predicted survival rates using abridged life tables and compute relative survival rates. From 1952 to 1985, a total of 1289 lung cancer patients underwent surgical resection of lung cancer in our department. We calculated some kind of survival rates according to age, stage, and operative procedure. Each case was classified according to age (5-year periods), year of operation (5-year periods), and sex. The 5-year survival rate indicated by the abridged life tables in each class was regarded as the 5-year predicted survival rate of the case. The mean of 5-year predicted survival rates of all cases in a group was regarded as being the 5-year predicted survival rate of the group. The ratio (actual survival rate of the group/predicted survival rate of the group) was also calculated. The ratio of the patients who had stage O, I, or II diseases tended to decrease according to age. This fact supposed that the number of deaths resulting from other diseases with no recurrence of lung cancer in which surgical treatment contributed to death increased in the elderly. In the other hand, this tendency did not exist in the patients who had stage IIIA diseases.

An 80-year-old man was admitted to our division because of hemosputum, cough, and chest pain for three months. A chest roentgenogram, chest CT scanning, and bronchoscopic examinations revealed adenocarcinoma of the lung with atelectasis of the right upper lobe. The patient developed radiation pneumonitis after receiving radiation therapy (5,100 cGy) for lung cancer. At the same time, the right upper lobe atelectasis improved and movement of infiltrates consistent with radiation pneumonitis to the middle lung fields occurred. A chest roentgenogram taken when the atelectasis had improved revealed the absence of pneumonitis shadows in the right upper lobe, suggesting that the atelectatic lung escaped radiation pneumonitis.

To evaluate the usefulness of Ga-67 citrate scintigraphy in the early detection of radiation pneumonitis, scintigrams from 103 patients who were treated with radiation therapy for lung cancer were retrospectively analyzed with regard to abnormal Ga-67 uptake after radiation therapy in sites other than the original or recurrent tumors. Sixteen (20%) of the 80 asymptomatic cases showed positive Ga-67 scintigrams. All of the other 23 symptomatic cases showed positive Ga-67 scintigrams. Thirteen (57%) of these 23 cases had negative chest radiographs although their Ga-67 scintigrams were positive. Detection of radiation pneumonitis by Ga-67 scintigraphy was significantly earlier than that possible by chest radiography (P less than 0.01). These data suggest that Ga-67 scintigraphy is more useful and sensitive than chest radiography for the early detection of radiation pneumonitis.

We define a solitary pulmonary noncalcified nodule (NPS) as a single focal rounded or ovoid lesion in the lung parenchyma, less than 4 cm in diameter, without associated adenopathy, atelectasis or pneumonia. An NPS, in the absence of a known primary malignancy, can be lung cancer (NPSM), a metastasis of unknown origin (NPSMT), or a benign lesion (NPSB). The best approach to the management of NPS and the value of CT are still controversial and uncertain. The finding on cross-section CT of a bronchus leading directly to, or contained within, the nodule is called "positive CT bronchus sign" (CT-BS). Our study was aimed at investigating the usefulness of CT bronchus sign, as studied on thin-slice (2 mm thick) CT sections, in order to establish the most appropriate diagnostic sequence in patients with solitary noncalcified pulmonary nodules (NPS). We evaluated 47 NPS (9 NPSB, 34 NPSM and 4 NPSMT) with thin-slice CT to detect the presence of CT bronchus sign. Seventeen cases had CT-BS (15 NPSM; 1 NPSB; 1 NPSMT); of them, 13 were diagnosed by means of transbronchial biopsy and brushing (TBB). Only one case (NPSM) of the 30 (19 NPSM; 3 NPSMT; 8 NPSB) without CT-BS, was diagnosed by TBB. TBB was negative in the 9 NPSB. The CT-BS is not pathognomonic of malignancy; in fact, the sign was observed in NPSB (one tuberculoma) too. Our results suggest that the CT bronchus sign is valuable in predicting the success of TBB in malignant solitary pulmonary nodules. On the other hand, it seems to be useless for NPSB. Therefore, to establish the most appropriate diagnostic sequence, thin-section CT should be performed in each patient with peripheral noncalcified lung lesions to plan whether TBB or transthoracic needle aspiration should come next. If biopsy results are poor, either surgery or the "wait and watch for growth" approaches can be suggested. The choice can be guided by the presence of predisposing factors for cancer or infection.

The number of patients reported to have undergone bronchoplastic procedures has increased nearly fourfold in the past decade. These techniques represent excellent surgical therapy for patients with benign endobronchial lesions, traumatic airway disruptions, or tumors of low-grade malignant potential, and for select patients with surgically resectable lung cancer. Eighty-nine percent of bronchoplastic procedures are performed for malignancy. We reviewed 1,915 bronchoplastic procedures for carcinoma reported over the past 12 years to determine the incidence of complications and survival. Complications included local recurrence (10.3%), 30-day mortality (7.5%), pneumonia (6.7%), atelectasis (5.4%), benign stricture or stenosis (5.0%), bronchopleural fistulas (3.5%), empyema (2.8%), bronchovascular fistulas (2.6%), and pulmonary embolism (1.9%). Results were further stratified into sleeve lobectomy and sleeve pneumonectomy groups. Five-year survivals for stage I, II, and III carcinoma were 63%, 37%, and 21%, respectively. Sleeve lobectomy for carcinoma extends surgical therapy to select patients with complication rates comparable to pneumonectomy and long-term survival similar to that for conventional resections.

Imipenem/cilastatin sodium (IPM/CS) was used to treat respiratory tract infections (RTI) in 54 patients with lung cancer. Out of the 54 patients studied, 53 were evaluable for the utility of IPM/CS; 42 had pneumonia, 9 had obstructive pneumonia, 1 had a lung abscess and 1 had acute bronchitis. The efficacy rate was 71.7%. Seventeen causative organisms were isolated from 14 patients. They included Staphylococcus aureus 5 strains, Staphylococcus epidermidis 4 strains, Staphylococcus sp. 2 strains, Enterococcus faecalis 1 strain, Pseudomonas aeruginosa 2 strains, Pseudomonas fluorescens 2 strains, Acinetobacter sp. 1 strain, and the eradication rate was 81.8%. Clinical adverse effects (nausea and vomiting) were observed in 1 patient. Abnormalities in laboratory test results were observed in 3 patients. They disappeared or returned to normal values after completion of therapy or discontinuation of IPM/CS administration. IPM/CS appears to be a useful antibiotic for RTI in patients with lung cancer.

The importance of smoking and other factors for lung cancer in women was investigated in a case-control study of women who had previously received a multiphasic health checkup at Northern California Kaiser Hospitals. Smoking and medical histories for 217 cases and matched controls were obtained from the multiphasic questionnaire. Odds ratios (ORs) and confidence intervals (CIs) associated with cigarette smoking were 35.1 (95% CI 4.8-256) for squamous and small cell and large cell carcinomas combined and 2.5 (95% CI 1.3-5.1) for adenocarcinoma. After adjusting for smoking, risk was increased in women with a family history of lung cancer (OR 1.9, 95% CI 0.7-5.6) and family history of any cancer (OR 1.8, 95% CI 1.0-3.2). A significant interaction existed between smoking and family history. Women with a history of bronchitis, pneumonia, or emphysema were at increased risk, whereas women with a history of asthma or hay fever experienced a significantly lower risk for lung cancer.

In a non-randomised study in six centres in the UK, 24 patients with previously untreated small-cell lung cancer of limited extent were treated with a regimen of alternating chemotherapy and radiotherapy to assess response, toxicity, and the feasibility of applying such a regimen on a multicentre basis in the UK. The intention was to give six courses of chemotherapy on five consecutive days at 4-week intervals: etoposide 75 mg m-2 on days 1, 2, and 3; doxorubicin 40 mg m-2 on day 1; cisplatin 100 mg m-2 on day 2; and cyclophosphamide 300 mg m-2 on days 2, 3, 4 and 5. A dose of 20 Gy thoracic radiotherapy was to be given following the 2nd and the 3rd courses, and one of 15 Gy following the 4th course. After 12 patients had been admitted, the cisplatin dosage was reduced to 80 mg m-2 because of unacceptable toxicity. Two patients were withdrawn during treatment on review of their histology because their diagnosis was found to be incorrect. Only one patient of the 12 treated with cisplatin 100 mg m-2 was able to complete treatment, compared with five of the eligible ten given the lower dosage. Among the 22 patients with confirmed small-cell disease, a complete response was reported in 14 (64%) and a partial response in a further three (total response rate 77%). Myelosuppression was the commonest serious adverse effect. It occurred in 19 of the 24 patients and gave rise to septicaemia in five, four of whom were receiving the higher cisplatin dose. Sixteen patients required blood transfusion and ten platelet transfusion. Vomiting, oesophagitis, and peripheral neuropathy occurred in 12, four and four patients, respectively, and radiation pneumonitis developed in two. Treatment was considered a contributory cause of death in four. The working party concluded that the alternating regimen was feasible in only a small proportion of centres in the UK, and decided not to embark on a multicentre randomised trial comparing alternating with conventional scheduling.

From 1955 to April 1989, 70 patients underwent bilobectomy for the treatment of primary lung carcinoma. Thirteen patients (18.6%) underwent right upper and middle lobectomy (UML), while 57 patients (81.4%) underwent right middle and lower lobectomy (MML). Indications for bilobectomy were cancer invasion into intermediate bronchus (34%), tumor extending to neighbouring lobe across a fissure (29%), interlobar lymph nodes metastasis with or without invasion to intermediate bronchus (24%), vascular invasion (5%), and others (7%). Squamous cell carcinoma was present in 31 patients, adenocarcinoma in 28, large cell carcinoma in 5, small cell carcinoma in 4 and others in 2. About 60 percent of the patients had Stage III or IV diseases. Postoperative complications occurred in 27 patients (38.6%) and 3 died within 30 days after operation (operative mortality rate. 4.3%). Pneumonia, empyema, atelectasis and arrhythmia were prominent postoperative complications. There were no statistically different postoperative complication rates between those with UML and those of MLL. Five-year survival rate of the patients with bilobectomy for lung cancer was 25.7%, which was between those with single lobectomy (36.9%) and those with pneumonectomy (5.6%). However, there was no statistical difference in 5-year survival rate among operative procedures in each stage.
