Although esophagogastrectomy offers the best chance for cure and alleviation of dysphagia in the treatment of esophageal carcinoma, the operative mortality and morbidity can be prohibitively high. To investigate means for reducing the rate of surgical complication, a study was made of a six-year series of 36 procedures involving 32 esophagogastrostomies and four colon interpositions. Patient survival rates were 60 percent at one year, 40 percent at two years, and 9 percent at five years with a mean survival of 22 months. Histology of the tumor did not significantly affect prognosis. The three operative mortalities were caused by pulmonary insufficiency in one overhydrated patient, and coagulopathy in two alcoholic patients with underlying liver disease. Anastomotic leakage, the precipitating factor for the majority of operative mortalities in the recent literature, occurred in one non-fatal case. This low incidence is linked to the implementation of steps to maximize blood supply and minimize tension on the anastomosis line. Anastomotic stricture was seen and easily dilated in three patients. The five cases of intra-esophageal tumor recurrence which occurred despite tumor-free margins may have been avoided by more extensive resection.

Phrenic nerve palsy secondary to benign thyroid enlargement is a previously unreported complication. Large goiters, particularly substernal, may impinge upon adjacent structures, often leading to significant symptoms such as dysphagia or dyspnea due to airway compression. The phrenic nerve may be stretched by a large goiter along its course in the neck, but the more likely site of injury is the point at which it enters the thoracic cavity adjacent to the first rib. Such an injury, caused by compression, may go unrecognized if unilateral, as symptoms would be uncommon. However, bilateral phrenic nerve palsy can cause significant dyspnea due to pulmonary insufficiency, particularly in an elderly patient with cardio-pulmonary disease. Early operative treatment of the goiter may prevent this complication or limit its severity, thus avoiding permanent nerve injury.

During the past 2 years, 3 anomalous right subclavian artery aneurysms have been encountered at the St. Louis Heart Institute. The 1st patient, a 72-year-old woman, was found to have an asymptomatic 5-cm-diameter anomalous right subclavian artery aneurysm after surgery for suspected rupture of an abdominal aortic aneurysm. Resection was not attempted because of her poor cardiopulmonary and renal condition. One year later, the patient remains alive with marked cardiopulmonary limitations. The 2nd patient, a 77-year-old man, experienced dysphagia and severe weight loss because of a 14-cm-diameter aneurysm. Three days after undergoing surgical repair, he required reoperation for graft occlusion with right upper-extremity ischemia. Six months after hospital discharge, he died of pulmonary insufficiency and metastatic colon cancer. The 3rd patient, a 73-year-old woman, required emergency surgical intervention because of acute rupture and hypovolemic shock. Thirteen days later, she died of aspiration, asphyxia, and cardiac arrest. On the basis of our experience and a review of the literature, we conclude that symptomatic anomalous right subclavian artery aneurysms are rare, and that surgical intervention entails a relatively high morbidity and mortality rate. If long-term survival is anticipated, associated medical illnesses should be considered before surgery is undertaken.

Combined modality treatment for esophageal carcinoma seems to improve survival over surgery alone. Different combinations of cytotoxic drugs have been studied to improve antitumor efficacy and limit the toxicity of chemoradiotherapy (CRT) with inconsistent results. We present a prospective study of neoadjuvant CRT with or without paclitaxel in chemotherapy schedule. One hundred seven patients (93 males, 14 females), median age 59 years (range 44-76), with operable esophageal cancer were enrolled. They received the following neoadjuvant therapy: Carboplatin, area under curve (AUC) = 6, intravenously on days 1 and 22, 5-fluorouracil (5-FU), 200 mg/m(2)/day, continuous infusion on days 1 to 42, radiation therapy 45 grays/25fractions/5 weeks beginning on day 1. Forty-four patients (41%) were furthermore non-randomly assigned to paclitaxel 200 mg/m(2)/3 h intravenously on days 1 and 22. Nutritional support from the beginning of the treatment was offered to all patients. Surgery was done within 4-8 weeks after completion of CRT, if feasible. All patients were evaluated for grade 3 plus 4 toxicities: leukopenia (28%), neutropenia (30%), anemia (6%), thrombocytopenia (31%), febrile neutropenia (6%), esophagitis (24%), nausea and vomiting (7%), pneumotoxicity (8%). Seventy-eight patients (73%) had surgery and 63 of them were completely resected. Twenty-two patients (20%) achieved pathological complete remission, and additional 20 (19%) had node-negative and esophageal wall-positive residual disease. There were 10 surgery-related deaths, mostly due to pulmonary insufficiency. Twenty-nine patients were not resected, 15 for early progression, 14 for medical reasons or patient refusal. After a median follow-up of 52 months (range 27-80), median survival of 18.0 months and 1-, 2-, 3- and 5-year survival of 56.7, 37.5, 27.0 and 21% was observed in the whole group of 107 patients. Addition of paclitaxel to carboplatin and continual infusion of FU significantly increased hematologic and non-hematologic toxicity, but treatment results as overall survival or time to progression did not differ significantly in groups with and without paclitaxel. Patients achieving pathological complete remission or nodes negativity after neoadjuvant therapy had favorable survival prognosis, whereas long-term prognosis of node positive patients was poor. Distant metastases prevailed as a cause of the treatment failure. Factors significant for survival prognosis in multivariate analysis were postoperative node negativity, performance status, and grade of dysphagia. Addition of paclitaxel to carboplatin and continual FU significantly increased hematologic and non-hematologic toxicity without influencing efficacy of the treatment. This study confirmed improved prognosis of patients after achieving negativity of nodes. Distant metastases prevailed as cause of the treatment failure. Prospectively, it is important to look for a therapeutic combination with better systemic effect.
