This is a report of the initial (prevalence) screening for lung cancer in a population of 10.040 cigarette-smoking men 45 yr of age and older, recruited from metropolitan New York. All had posteroanterior and lateral chest roentgenograms, and approximately half the men, randomly chosen, also had sputum cytology (dual screen). Fifty-three confirmed lung(More)
This paper is concerned with the relationship between the occurrence of metastases and the size of primary cancers. We consider two probabilistic characterizations of this relationship. First is the distribution function of tumor sizes at the point of metastatic transition; second is the probability that detectable metastases are present when the cancer(More)
The Memorial Sloan-Kettering lung cancer screening program was begun in 1974 to evaluate sputum cytology as a supplement to the annual chest x-ray examination for early detection and diagnosis. The 10,040 adult, male cigarette smokers who enrolled were randomly assigned to receive annual chest x-ray examinations only or a dual screen with annual chest x-ray(More)
A mathematical model of the progression kinetics of lung cancer in a periodically screened population is proposed and data collected by the Memorial Sloan-Kettering Cancer Center in New York are used for parameter estimation. It is assumed that the development of adenocarcinoma of lung is a stochastic process with two stages, early and advanced,(More)
Nine hundred sixty-one patients underwent operations for the treatment of carcinoma of the lung; 18 percent of these were 70 years of age or older. The effect of various factors, singly or in combination, on the incidence of postoperative complications was assessed. Variables included age, sex, cardiopulmonary status, cell type, stage of the disease, and(More)
From 1984 to 1991, 136 patients with histologically confirmed non-small cell lung cancer and stage IIIa (N2) disease received two to three cycles of MVP (mitomycin + vindesine or vinblastine + high-dose cisplatin) chemotherapy. All patients had clinical N2 disease, defined as bulky mediastinal lymph node metastases or multiple levels of lymph node(More)
We consider a life testing situation in which systems are subject to failure from independent competing risks. Following a failure, immediate (stage-1) procedures are used in an attempt to reach a definitive diagnosis. If these procedures fail to result in a diagnosis, this phenomenon is called masking. Stage-2 procedures, such as failure analysis or(More)
We assessed the effect of surgery on survival from stage I non-small-cell lung cancer based on data collected in these screening programs. The majority of patients diagnosed in each program were treated by surgical resection, but 5 percent of the Sloan-Kettering group, 21 percent of the Hopkins group and 11 percent of the Mayo group failed to receive(More)
The Memorial Sloan-Kettering Lung Cancer Detection Program is described, and data from this study are reported and analyzed. The program enrolled 10,040 cigarette-smoking men who were screened for at least 5 years by annual chest radiographs; half the men randomly selected also had 4-monthly sputum cytologic examinations. Of the 354 lung cancers that(More)
