The evaluation and treatment implications of isolated pulmonary nodules in patients with a recent history of breast cancer.

BACKGROUND: Breast cancer patients with pulmonary lesions are often assumed to have metastatic disease and treated palliatively. We evaluated the proportion of these patients who actually have primary lung tumor (PLT) and assessed their outcome. METHODS: We performed a 10-year retrospective review of the cancer registry in a community hospital system. RESULTS: Among 54 breast cancer patients with pulmonary nodules, biopsy was pursued in 30. Although metastatic breast cancer (MBC) was presumed in 24, biopsy showed MBC in 9 patients and PLT in 21. The two groups differed in age, stage, breast tumor size, nodal involvement, and estrogen receptor (ER) positivity. However, no variable excluded the possibility of PLT. Of those with PLT, 11 had early-stage lung disease; 9 underwent curative resection. CONCLUSIONS: Women with breast cancer and 1 or more pulmonary lesions without evidence of other metastatic disease require work-up of pulmonary lesions. Aggressive evaluation can afford treatment of lung cancer and impact survival.

Modification to the Ross procedure to prevent autograft dilatation.

Dilatation of the pulmonary autograft is a problem described following Ross procedure for aortic valve replacement. Patients at risk seem to be those with aortic insufficiency, bicuspid aortic valves, and those with aneurismal ascending aortas. We describe a technique for encasing the pulmonary autograft in a Dacron tube to prevent dilatation in these patients. This technique is reproducible and includes sewing the coronary arteries to all layers of the autograft and Dacron construct. Short-term follow-up shows excellent outcomes with respect to autograft valve function and lack of annular or sinotubular dilatation. This procedure may be useful for extending the Ross procedure to young adults, where autograft growth is no longer needed, to provide a non-dilatable neoaortic root.

Advances in congenital heart surgery.

PURPOSE OF REVIEW: We provide an overview of the past year's literature on congenital heart surgery. RECENT FINDINGS: This review focuses on selected disease entities, operative techniques, perioperative management strategies, and quality of care. SUMMARY: Congenital heart surgery is an evolving field.

Recurrent pulmonary artery sarcoma.

Pulmonary artery sarcomas are a diagnostic and therapeutic challenge. Most patients are initially thought to have pulmonary emboli, and during embolectomy, a sarcoma is found. Given the significant morbidity and mortality of cardiac sarcomas, an aggressive strategy for resection is indicated, as this leads to benefits in disease-free and overall survival. Imaging tests and clinical signs and symptoms may assist in accurate preoperative determination of pulmonary artery sarcoma. We present an interesting case of a patient with pulmonary artery sarcoma who underwent successful re-resection, along with a brief discussion regarding preoperative imaging and the surgical resection of these tumors.
