Metastatic pattern in recurrent breast cancer. Special reference to intrathoracic recurrences.
The anatomical and temporal patterns of recurrence were studied in 401 patients with first recurrence of breast cancer. All patients underwent the same scheduled investigation program: history, physical examination, blood tests, bone scanning, bilateral iliac crest biopsy, radiologic bone survey, chest x-rays, and ultrasound scanning of the liver. The current article focuses on the diagnosis of intrathoracic (ITH) recurrence. Most patients recurred in a single site and 50% of the recurrences were diagnosed within the first 2 years from initial diagnosis. Chest x-ray revealed ITH recurrence in 27% (109 patients), and in 8% the lung, pleura, and/or mediastinum were the only signs of recurrence. Generally, the status of primary demographic, clinical, and pathoanatomical characteristics were not predictive as to the development of ITH recurrence, although patients with pleural recurrences often had centrally located primary tumors, locally advanced disease, and often received adjuvant radiotherapy. Clinical symptoms and signs of ITH recurrence were present in only one third of the patients, and the diagnostic specificity and sensitivity of serum lactate dehydrogenase were only 33% and 85%, respectively. Since ITH recurrences often are silent, and since recurrence in this site may have both prognostic and therapeutical implications, routine chest x-ray is indicated in all patients with first recurrence of breast cancer.
