Sublobar resection and lobectomy have equivalent survival for patients with clinical stage IA non-small cell lung cancer in the context of computed tomography screening for lung cancer.

Background. Medical records of 50 patients with malignant mesothelioma were reviewed to determine the clinical features and factors influencing survival. Methods. Charts of all patients whose conditions were diagnosed as malignant mesothelioma were abstracted and analyzed by statistical software. Results. The male‐to‐female ratio was 4:l. The age distribution was younger than 45 years of age, 10%; 45–54 years of age, 12%; 55–64 years of age, 37%; 65–74 years of age, 33%; and 75 years of age or older, 8%. Both mean and median ages were 58 years. Among the 32 patients in whom asbestos exposure was recorded, 24 had documented exposure. The sites were pleura, 73%; peritoneum, 20%; and both, 6%. The histologic types were epithelial, 51%; sarcomatous, 10%; mixed, 15%; and not specified, 24%. The stage at presentation was Stage I, 37%; 11, 39%; 111, 12%; IV, 6%; and unknown, 6%. The common symptoms in pleural disease were dyspnea and pain; in peritoneal disease, abdominal distension and pain were common. The median time from first symptom to diagnosis was 3 months (range, 0–23 months). The median survival after the appearance of symptoms, the diagnosis, and the treatment were 13,10, and 8 months, respectively. Conclusions. The survival was independent of age, sex, and smoking behavior. It was longer in patients with earlier‐stage disease, a good performance status, a longer duration of symptoms, an absence of pain, and who were treated with combined surgery and chemotherapy. Chemotherapy using anthracyclines yielded more remissions (9 of 21) than that using nonanthracyclines (0 of 13). The remission rate after primary chemotherapy with anthracyclines (7 of 16) may be higher than in recurrent tumor (2 of 14). In future trials, stratifization into primary chemotherapy and chemotherapy of recurrent cancer is suggested. There is a need for multi technique trials incorporating primary Chemotherapy.

The frequency and extent of surgery for nonmalignant disease can be minimized in a CT screening program and provide a high cure rate for those diagnosed with lung cancer and undergoing surgical resection.

Primary choriocarcinomas of the lung are extremely rare. Like choriocarcinomas elsewhere, they possess rapid growth ability and a high propensity to metastasize. There is minimal information available on the treatment of lung choriocarcinoma. In the case reported herein, neoadjuvant chemotherapy with 5-fluorouracil (5-FU) infusion, etoposide, and cisplatin induced a partial response permitting complete excision of a massive tumor of the right upper lobe involving the chest wall and superior vena cava. The patient relapsed with a metastasis to the brain that was surgically excised. Contralateral lung metastases were soon noted and responded well to systemic chemotherapy; yet the patient died of a new brain metastasis. To our knowledge, this is the first example of a primary choriocarcinoma of the lung treated with intensive multimodality therapy. The latter seems to offer a potential benefit if certain guidelines are followed.

The relation between time to first shock and clinical outcome was studied in 60 patients who received an automatic implantable cardioverter-defibrillator (AICD) from August 1983 through May 1988. The mean (+/- SD) patient age was 64 +/- 10 years, 82% were men and the mean ejection fraction was 33 +/- 13%. During follow-up, 38 patients (63%) had one or more shocks; there were no differences in age, gender distribution or ejection fraction at entry between the shock and no shock groups. Among 51 patients with coronary artery disease, 31 (61%) had one or more shocks, whereas all seven patients with cardiomyopathy had one or more shocks (p less than 0.05). Neither of the two patients with idiopathic ventricular fibrillation had shocks. Of the 13 deaths, 12 occurred during post-hospital follow-up and 1 during the index hospitalization. Of the four sudden post-hospital deaths, only one was due to tachyarrhythmia in the absence of acute myocardial infarction. All four sudden deaths and five of eight post-hospital nonsudden deaths occurred in patients who had had one or more appropriate shocks during follow-up. Eight of the nine first appropriate shocks among patients who subsequently died occurred within the first 3 months of follow-up, but the actual deaths were delayed to a mean of 14.1 +/- 13.9 months (p less than 0.05). The mean time to all deaths was 14.8 +/- 13.1 months. The ejection fraction was significantly lower among patients who died than among patients who survived (25 +/- 7% versus 35 +/- 14%, p less than 0.02), but it did not distinguish risk of first shocks.(ABSTRACT TRUNCATED AT 250 WORDS)

Factors that improved long-term survival after left ventricular surgical remodeling were intraventricular patch repair, preoperative ejection fraction of 26% or greater, and pulmonary artery occlusive pressure of 17 mm Hg or less without the need for balloon pump assist.
