Background. Lung metastases are rarely a significant factor in the management of prostate cancer. The usual pattern of spread is via lymphatic pathways, with pulmonary metastases virtually always occurring with osseous metastases. Previous reports suggest that androgen deprivation often fails to produce significant improvement in patients with pulmonary metastases; however, in the authors' experience, it has been successful in achieving objective responses.
Methods. A retrospective review of a large prostate cancer data base was performed to identify patients with adenocarcinoma of the prostate and radiographic evidence of pulmonary metastases. A unique case of isolated pulmonary metastases with exsanguinating hemoptysis is described to illustrate the dramatic response to androgen deprivation.
Results. Of 1290 patients with biopsy‐proven adenocarcinoma of the prostate, in 47 (3.6%) patients radiologic evidence of pulmonary metastases was observed. Twenty‐six (2.0%) patients demonstrated pulmonary metastases at the time of initial detection of metastatic disease. The radiographic appearance of pulmonary metastases was consistent with lymphangitic spread in the majority of patients. Of patients who received no hormonal therapy before the development of pulmonary metastases, 76.5% showed improvement in the appearance of their pulmonary lesions with androgen deprivation. As expected, survival was longer for those patients presenting with hormone‐naive disease and pulmonary metastases than for patients with hormone‐refractory disease and pulmonary metastases. The difference in survival, however, was not statistically significant.
Conclusions. Pulmonary metastases are not encountered commonly in patients with prostate cancer. Androgen deprivation remains the most effective treatment and, among hormone‐naive patients, objective response is common. The prognosis for patients with hormone‐naïve disease and pulmonary metastases is not necessarily worse than for patients with metastatic disease at other sites. Cancer 1995;75:2706–9.
Axillary lymph nodes are the most important prognostic indicator for survival in breast cancer. Our mathematical model suggests the daily increased risk of axillary metastases due to treatment delay is 0.028% for tumors with moderate doubling times of 130 days and 0.057% for tumors with rapid doubling times of 65 days. This minimal maternal risk may be acceptable to some third-trimester pregnant women with early breast cancer, who prefer organ-sparing treatment with radiation after delivery to a mastectomy during pregnancy. This model further quantitates the increased risk of mortality borne by pregnant women whose breast cancer diagnosis is delayed.
The third reported case of fatal malignant cystosarcoma phyllodes in an adolescent female is described. The patterns of local recurrence and distant spread in this case, including the response to treatment, were similar to those reported in the first reported case in this age group. A review of the treatment recommendations for cystosarcoma phyllodes revealed that the surgical procedure of choice for the malignant variant has remained controversial, and the conclusions regarding the ineffectiveness of radiation and chemotherapy have been based on insufficient data handed down through the years. Our observations in this case and the information we have obtained from the literature have prompted us to recommend a multidisciplinary approach for malignant cystosarcoma phyllodes, particularly in young women, and we are calling for a multi-institutional study group to further investigate this disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
