Long term survival after resection for bronchogenic carcinoma

Abstract: Of 915 resections for bronchogenic carcinoma over a 25-year period (1945-1969), 249 patients survived over 5 years; 127 of the patients eligible survived over 10 years, 61 over 15 years, and 22 over 20 years The case material was divided into three time periods: 1945-49, 1950-59 and 1960-69, as well as by extent of resection Lobectomy became the operation of choice, pneumonectomy being reserved for the more extensive lesions Observed survival rates at 5, 10 and 15 years for 561 patients in the lobetomy series were 35, 22 and 15%, respectively, but strikingly increased to 41, 28 and 19% in the 1960-69 period Observed rates for 354 patients having pneumonectomies were similar for three time periods, being 16, 8 and 6% at 5, 10 and 15 years, respectively Relative survival rates for the lobectomy series at 5, 10 and 15 years rose from 33, 28 and 26%, repectively, in the 1950-59 period to 50, 39 and 35% in the last time period, becoming a near horizontal curve segment after 5 years Dominant factors in survival were extent of the lesion and stage of nodal involvement, histologic type and location being less significant

Survival from Malignant Disease

Abstract: The question: Why does a patient die from cancer? is seldom asked. It is usually taken for granted that a malignant tumour proliferates, infiltrates, and perhaps metastasizes, until it kills. Progressive and remorseless growth tends to be regarded as the hallmark of cancer and a sufficient cause of death.

Survival in breast cancer: study of 283 patients.

Abstract: Records of 283 women with breast cancer diagnosed from 1965 through 1973 at l'Hopital du Saint-Sacrement were studied for survival at 3 and 5 years. These were all patients who had not previously received cancer-directed treatment. Life-table methods based on full intervals only were used to analyze survival. Adjustment for deaths from other causes was provided by computing the expected and relative survival rates. The 5-year relative survival rates (%) were 60.2+/-4.1 for the total group of 283 patients, 87.9+/-4.5 for the 142 with localized disease and 44.9+/-59 for the 118 with regional spread. Of the patients with disease that was either localized or regional, 84% underwent total mastectomy. The age of patients at entry did not differ from that of cases reported to the Quebec Tumour Registry. The significant increase over time in the proportion of patients with localized disease would be expected to reduce the Quebec death rate from breast cancer in future if the better survival of these patients is not simply a function of earlier diagnosis.
