Based on the surgical pathology and survival for patients in previous trials using a neoadjuvant program of chemotherapy (5-fluorouracil [5-FU]-cisplatin) and radiation (3,000 cGy) before surgery for squamous-cell cancer (SCC) of the esophagus, a nonoperative pilot trial was designed to test if survival and recurrence would differ from our historical controls if routine esophagectomy was eliminated. Twenty patients were treated. The protocol called for the delivery of 5-FU infusion (1,000 mg/m2/d X 4 d) days 1 to 4 and 29 to 32 with cisplatin (100 mg/m2) day 1 and 29 sandwiched around external beam radiation (3,000 cGy over 3 weeks). Mitomycin C (10 mg/m2) day 57 was administered with bleomycin infusion (20 U/d X 4 d) days 57 to 60 and 78 to 81. A radiation boost of 2,000 cGy was administered 200 cGy/d days 99 to 103 and 106 to 110. Clinical pulmonary toxicity forced withdrawal of bleomycin and mitomycin C in the last four patients treated; two further courses of 5-FU-cisplatin were administered instead. The median measurement of the 20 esophageal lesions by barium swallow was 7 cm. Four patients underwent salvage surgery to prevent life-threatening aspiration pneumonia. The median survival for the 20 patients is 22 months, with a range from 6 to 39+ months. The six patients clinically without cancer are alive 22+ to 39+ months (median, 35+ months). Three patients died manifesting only local (infield) recurrence; five died manifesting only distant recurrence; and five developed local and distant recurrence. While the toxicity of the four drug regimen as administered was prohibitive, the survival and quality of survival is superior to the regimen previously used, which routinely used surgery after preoperative chemotherapy and radiation.
Mediastinitis and/or sternal dehiscence developed in 143 out of 10,263 patients (1.4%) who underwent cardiac surgery between January 1979-December 1993. Mediastinal drainage, sternal debridement and early wound closure with pectoralis major and/or rectus abdominalis muscle flaps was the treatment employed. Between these two stages of treatment, massive hemorrhage developed in seven patients (0.07%) from a tear of the anterior wall of the right ventricle (RV). Six patients survived. Temporary control of the bleeding was achieved with digital or full palm pressure control of the ventricular tear. This was followed by immediate repair in the operating room (OR). The only death was due to exsanguination in the intensive care unit. The other six patients were taken to the OR. The anterior RV was freed from the underside of the sternum and the RV tear repaired with or without the aid of femoral-femoral bypass. These six then had muscle flap wound closures at that time or shortly after. All six were hospital survivors and are currently alive. We believe that RV rupture results from the sternal edges pulling the anterior surface of the RV apart, since the RV is stuck to the underside of the sternum. This experience indicates that the RV must be freed in all cases during initial sternal debridement. Hopefully this simple maneuver will prevent this horrendous complication.
Sinus of Valsalva aneurysms are a rare cause of angina or myocardial infarction. We describe a patient with unstable angina and massive unruptured aneurysms of both coronary sinuses causing severe distortion of both coronary ostia, to our knowledge not previously reported. This unusual patient underwent aortic valve replacement, ascending aortic repair, and coronary artery bypass. At 11-year follow-up, she had developed severe mitral stenosis and prosthetic aortic valve stenosis. Review of the literature reveals 30 reported cases of Sinus of Valsalva aneurysm complicated by coronary insufficiency or infarction, involving either the left (20 cases) or the right coronary sinus (10 cases). We emphasize the poor outcome of these patients, especially if treated conservatively.
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.
