From October 1986 to January 1991, 47 patients with esophageal cancer (29 squamous, 18 adenocarcinoma) were treated with simultaneous radiotherapy (3000 or 3600 cGy) and chemotherapy (infusional 5-fluorouracil, cisplatin) delivered during a 5-week period. This treatment was well tolerated; 44 patients (94%) completed a full course of therapy, 40 (85%) had relief from dysphagia, and 21 (45%) noted either weight gain or no net weight loss. One patient (2%) died of complications (tracheoesophageal fistula, perforated ulcer) during chemotherapy and radiotherapy. The remaining 46 patients were referred for operation. Six refused because of excellent relief of their dysphagia, and one was denied operation. Thirty-nine patients went to operation, and 34 (83%) had lesions that were resectable. Eight of the 39 surgically treated patients (21%) had no evidence of residual tumor identified in the resected specimens. One of these complete responders died 7 weeks postoperatively after multiple complications (3% operative mortality rate). Three of the remaining seven have also died since the operation, one of recurrent cancer and two with no known recurrent disease. Actuarial survival in this present series was significantly better than that of our 1980 to 1985 historical control patients (p less than 0.005). There was no difference between patients with squamous carcinoma and those with adenocarcinoma with regard to the prevalence of complete response or long-term survival. Survival of the seven patients who did not undergo operation was comparable with that of the 34 patients in whom esophagectomy was performed. This study suggests that combined preoperative chemotherapy plus radiotherapy for esophageal cancer is well tolerated, provides excellent palliation of symptoms, allows for a high rate of resectability, is equally effective for squamous carcinoma and adenocarcinoma, and provides encouraging early results with regard to long-term survival. The data also call into question the role of esophagectomy, particularly in patients who have a complete response to preoperative therapy.

Most of the symptoms from a malignant tumor are caused by local invasion by the tumor, or obstruction, either at the site of the primary disease or by metastases. However, tumors can produce symptoms at a remote site. Patients with gastrointestinal malignancy may present with symptoms which include dysphagia, nausea, vomiting, abdominal pain, diarrhea, bleeding and ascites. Palliation gastrectomy delays or prevents these symptoms. About 30% of gastric carcinomas are inoperable at the time of presentation. Chemotherapy is rarely effective in the palliation of gastric carcinoma. Laser irradiation can be delivered to assay site accessible to fibreoptic endoscopy, which is an advantage over endocavity irradiation or diathermy fulguration. Ascites is a common and disabling implication in patients with advanced malignant disease. Spironolactone will increase urinary sodium excretion significantly and control their ascites. If spironolactone fails to control, useful control can be achieved by draining the ascites. Patients with carcinoma of the lung may present with symptoms that include cough, bloody sputum and dyspnoea. Pain in the chest wall is usually secondary to invasion of the parietal pleura, ribs or intercostal nerves. Lesions in the medial portion of the right upper lobe, or mediastinal metastases, may invade or compress the superior vena cava, causing venous hypertension with oedema of the head and arms. The patients may complain of dyspnoea, dysphagia, stridor and headaches. Radiotherapy can be expected to improve the quality of life for these patients. Successful palliation of symptoms is almost related to tumor regression. The problems of obstruction and bleeding from malignant tumor is common. Recently, laser techniques have been applied to aid in palliation of these problems. Malignant effusion may occur early and be the first signs of metastases. The aim of therapy is to evacuate the fluid and induce pleural adhesion. One of the sad situations that we have to face is the patient with recurrent cancer which complains of various symptoms. The relief of symptoms is the most important palliative therapy to them.

Endoscopic laser therapy (ELT) for palliation of cancer of the esophagus and the gastroesophageal junction was evaluated in 31 patients with far advanced disease. Initial technical success (94%) and initial improvement of symptoms (81%) were comparable to data reported previously. Complications were bleeding (6%), sepsis (6%), and tracheoesophageal fistula (6%). This analysis, however, addressed the impact of ELT on the remaining life of the patients. In 9 patients (29%) ELT was the only palliative alternative, and in 7 of these patients a fair functional success was achieved. In 13/21 (63%) of the patients with good initial functional result palliation could be preserved by repeated ELT until death from cachexia. Eight patients, however, were intubated in the follow-up period because of failure to keep the esophagus open. The dysphagia-free interval was only 4 weeks, and repeated ELT became progressively more difficult because of increased tumor load and increasing debility of the patient. 32% of the patients experienced ELT as more difficult than repeated dilations. Our data also suggest that duration of palliation after ELT alone lasts longer than palliation after dilation followed by ELT. Results of ELT were best in patients with recurrent cancer at the esophagogastric or esophagojejunal anastomosis.

Local radical thyroidectomy, including cervical lymph node dissection and combined circumferential resection of the trachea, has been performed over the past 20 years in 31 patients with differentiated cancer invading the trachea. The 5- and 10-year survival rates for these patients were 77.4% and 66.7%, respectively. In 19 of the 31 (61%) cases the recurrent nerve was resected because of direct cancer invasion. Bilateral recurrent nerve palsy occurred in 12 patients, 3 of whom were managed postoperatively using a T-shaped tube for preservation of the larynx. Hoarseness remained in 21 patients. In two patients with recurrent cancer invasion of the larynx, partial laryngectomy and hemilaryngectomy were performed, and reconstruction was done using ear cartilage without postoperative dyspnea or dysphagia. Parathyroid function is an important factor in regard to the quality of life of patients. In 22 patients at least one of the parathyroids was preserved. Postoperative calcium administration was necessary in 14 patients. Our long-term observations indicate that local radical thyroidectomy with combined resection of the trachea can serve as a useful treatment for advanced differentiated cancer invading the airway.

Radiation therapy for thoracic malignancies is often complicated by radiation-induced esophagitis. Symptoms of radiation esophagitis are nonspecific and include dysphagia, odynophagia, and chest pain. Patients receiving radiation therapy are also at risk for infectious esophagitis, which can be indistinguished clinically from radiation-induced esophagitis. We retrospectively reviewed data on patients who had esophagitis symptoms during or after thoracic radiation therapy and were referred for upper endoscopy. We sought to determine how often infectious esophagitis or cancer was present, as compared to radiation-induced esophagitis alone. Twenty-four upper endoscopies were performed on 16 patients over a three-year period to evaluate esophagitis symptoms. Forty-four percent of the patients endoscoped had infectious esophagitis or recurrent cancer diagnosed by endoscopy. No complications occurred from the procedures. Esophagoscopy is a safe procedure that should be considered, to exclude infection or cancer, in patients who develop esophagitis symptoms during or after thoracic radiation.
