124 Rhesus monkeys (Macaca Mulatta) were caught in the Taihang Mountain region, a high incidence area of human esophageal cancer in Northern China, in January 1989. Among them, two monkeys died of esophageal carcinoma in 1990. Case 1, a male monkey about 6.5 years old and weighing 14.5 kg, had symptoms of salivation, vomiting and dysphagia in February 1990. The symptoms became gradually more serious and died in March 1990. Postmortem examination revealed a huge tumor in the distal segment of esophagus, causing severe stricture of the organ. The tumor was classified as medullary type and histopathologically diagnosed as a well differentiated squamous cell carcinoma, with metastases to mediastinum and lymph nodes of right gastric group. Case 2, a female monkey about 11-year-old and weighing 10.0 kg, showed loss of appetite, tiredness, somnolence, coughing and vomiting in September and died in December 1990. Autopsy revealed an annular tumor involving the whole circumference of lower portion of the esophagus. The tumor was of ulcerative type and diagnosed as a well differentiated squamous cell carcinoma. The symptoms and pathological changes of the two monkeys showed high similarity to esophageal cancer in humans. We believe that the present findings would provide important leads for further study to clarify the etiology and pathogenesis of human esophageal cancer in this high incidence area of esophageal cancer.

Postoperative pulmonary complication and respiratory failure, frequently seen in undernourished patients such as those with esophageal cancer, were suspected to be due to respiratory muscle wasting caused by nutritional depletion. Based on this idea, the respiratory muscles obtained by biopsies during operation from diaphragm, external intercostal muscle, and rectus abdominis muscle were assessed histochemically in 32 patients. The specimens were stained for myosin ATPase to differentiate the types of muscle fibers, and then the size and distribution of the muscle fibers of each type were measured. In diaphragm muscle, cross-sectional areas of type 1 & 2 and the ratio of the area occupied by each fiber were usually the same; in external intercostal muscle, however, type 1 fibers were dominant and in rectus abdominis muscle, type 2 fibers were dominant. The cross-sectional area of each respiratory muscle fiber well correlated with certain anthropometrical indexes, and the nutritionally depleted cases, the muscle fibers were of a smaller size suggesting less respiratory muscle strength. The ratio of the area occupied by type 1 fibers in diaphragm muscle was linearly related to serum albumin, total cholesterol, and PNI (prognostic nutritional index). Type 2 fibers were dominant in malnourished patients, suggesting greater fatigue compared to well-nourished cases. Opposite findings were obtained in external intercostal muscle and rectus abdominis muscle, and the ratio of the area occupied by type 2 fibers was smaller in the undernourished cases, suggesting reduced maximum strength of these muscles.(ABSTRACT TRUNCATED AT 250 WORDS)

From 1977 to 1982, 62 patients with various advanced malignant solid tumors were treated by HD-MTX-CFR therapy and totally 129 courses were given. Majority of the patients suffered from malignant lymphoma (10), osteogenic sarcoma (11), lung cancer (16), esophageal cancer (3), breast cancer (3) and malignant melanoma (4). All were confirmed by cytology or pathology except one primary liver cancer. There were clinically measurable lesions in 59 patients for evaluation of the treatment, and 3 osteogenic sarcoma patients without metastasis were given a postoperative adjuvant chemotherapy. 33 out of 62 had received chemotherapy and/or radiotherapy before. Dose of MTX ranged from 2 to 3 gm per course in most patients and dose of CF, from 9 to 12 mg every 6 hours for 3 days. 2 (3.4%) patients achieved complete remission (1 osteogenic sarcoma and 1 malignant lymphoma) and 8 (13.6%), partial remission (1 osteogenic sarcoma, 5 malignant lymphoma, 1 esophageal cancer and 1 breast cancer) with a total response rate of 15.9%. No response was observed in all 16 lung cancers. The main side effects of HD-MTX-CFR therapy were leukopenia, thrombocytopenia, elevation of SGPT, nausea, vomiting, mucositis, skin rash, fever and fatigue. All patients were followed more than 3 years. 4 patients are still alive (9, 9, 4 and 7 years, respectively), including 3 osteogenic sarcoma patients who received postoperative adjuvant chemotherapy and 1 mycosis fungoides.

Twenty-four patients with epidermoid carcinoma of the esophagus have been treated, in a phase II trial, with methyl-GAG using a weekly schedule. Eighteen patients had received prior chemotherapy with cisplatin-containing combinations. Of 23 evaluable patients, four (17%) had partial remissions, each lasting 2 months. All patients had received prior chemotherapy. Toxic effects were manageable and included mild nausea and vomiting, mucositis, and fatigue. Using this schedule, methyl-GAG had modest activity in esophageal cancer, with acceptable toxicity. Its role in combination chemotherapy remains to be defined.

In order to test the hypothesis whether the breathing pattern is helpful in predicting weaning outcome in patients being weaned from mechanical ventilation, 38 patients who underwent operation for esophageal cancer were evaluated at weaning from mechanical ventilation (19 unsuccessful weanings, group U, and 19 successful weanings in age-matched patients, group S). Since all patients initially fulfilled our weaning criteria, ventilatory parameters such as tidal volume, respiratory frequency, minute ventilation, and arterial blood gas analysis showed no significant differences between the groups. The breathing pattern was registered quantitatively by means of respiratory inductive plethysmography at 3 cmH2O (0.3 kPa) of CPAP prior to weaning. The contribution of rib cage movement to tidal volume (%RC) was significantly greater in group U than in group S (P < 0.05). Indeed, 84% of the patients in group S showed %RC less than 50%, compared to only 16% of the patients in group U (P < 0.05). The results suggest that the breathing pattern is one important factor in predicting the outcome of weaning in patients after thoraco-abdominal surgery. Diaphragmatic fatigue is suspected to be the mechanism for the increase in the RC component in patients with unsuccessful weaning outcome.

We assessed the Quality of Life (QOL) of 116 patients with inoperable esophageal cancer who were mainly treated with radiotherapy between 1978 and 1993. Factors including dysphagia, weight loss, side effects of radiotherapy,P.S. and psychological status were assessed retrospectively. Dysphagia was assessed using a swallowing-function scoring system. Initial improvement in dysphagia occurred in 68% of the 71 assessable patients. Radiotherapy was also effective for the other symptoms, including swallowing pain, anterior chest pain and vomiting. Improvement rates were 73%, 60% and 82%, respectively. The major side effects were pain of the pharynx, general fatigue, epigastralgia and appetite loss. But most side effects resolved within 10 days after the end of radiotherapy. Improvement of dysphagia resulted in reduced weight loss of the patients. Average weight loss was about 3 kg/month before radiotherapy. This was reduced after radiotherapy to 0.78 kg/month in patients who had improvement of dysphagia and 1.69 kg/month for those without improvement. Improvement of dysphagia also affected favorably the psychological state of the patients. There were fewer cases of patient distrust of staff and less despair in those patients with improved dysphagia. Radiotherapy appears to contribute to better QOL in patients with inoperable esophageal cancer.

Irinotecan (Camptosar) is an active chemotherapeutic agent for lung, gastric, esophageal, and colorectal cancers and a potent radiosensitizer. This phase I study was designed to assess the maximum tolerated dose of weekly irinotecan combined with concurrent radiotherapy for patients with locally advanced, unresectable gastric, gastroesophageal junction, or esophageal cancer. Patients who received previous chemotherapy (excluding irinotecan) or who experienced recurrent cancer after surgery were eligible for this protocol. The total dose of radiation did not exceed 50.4 Gy (28 fractions of 1.8 Gy each). The starting dose level of irinotecan was 30 mg/m2 infused over 90 minutes given weekly for 5 weeks. Subsequent dose levels were increased in 10 mg/m2 increments to 40, 50, 60, and 70 mg/m2. Of 15 patients who have been enrolled to date, all are evaluable for toxicities and 12 for response. Major hematologic toxicities (grade 3/4) were neutropenia, chills, hemorrhage, and anemia. Grade 3/4 gastrointestinal toxicities included nausea, vomiting, dehydration, anorexia, and constipation. Other severe nonhematologic toxicities included fatigue, hypotension, and hypothermia, as well as cardiovascular toxicities. There was no severe diarrhea and no treatment-related deaths. Of the 12 evaluable patients, 7 (58%) responded, including 2 complete responses; 4 (30%) had no change and 1 had progressive disease. Survival ranged from 1 month to 15 months, with a median survival of 8 months. When the total dose of irinotecan given concurrently with radiotherapy was higher than 250 mg/m2, patients experienced significantly more severe grade 3/4 toxicities than with lower doses (P = .04), with no improvement in response rate. It was concluded that weekly doses of irinotecan of up to 60 mg/m2 with concurrent radiotherapy given over 5 weeks was feasible and demonstrated good response. This regimen did not cause severe diarrhea or pneumonitis, but neutropenia and fatigue were major toxicities. The study continues to accrue.

Background. Docetaxel and irinotecan have additive or synergistic activity in vitro and in vivo as well as differing toxicities and unique mechanisms of action. We conducted a phase I trial to determine the maximum-tolerated dose of docetaxel and irinotecan given on a weekly schedule. Methods. Eligible patients had advanced, incurable, solid tumors. Docetaxel was administered as a 1-hour infusion and escalated over four dose levels (25, 30, 35, and 40 mg/m(2)) followed by irinotecan administered over 30 minutes at a fixed dose of 50 mg/m(2). Treatment was administered weekly for four weeks followed by two weeks of rest. To improve tolerability, the schedule was modified to weekly administration for two weeks with one week of rest, and irinotecan was escalated over 3 dose levels (55, 60, and 65 mg/m(2)) with docetaxel fixed at 35 mg/m(2). Results. Forty-four patients were treated and the most common dose-limiting toxicity was diarrhea observed in 11% of patients. Severe neutropenia was rare (grade 4: 2%, grade 3: 23%). Other nonhematologic toxicities included nausea/vomiting, dehydration and fatigue. Partial responses occurred in two patients with pancreatic cancer, and one patient each with non-small cell lung and esophageal cancer. Conclusions. Weekly docetaxel and irinotecan is a promising non-cisplatin doublet with preliminary evidence of activity in advanced solid tumors. Diarrhea is the predominant dose-limiting toxicity but unlike the every 3 weeks schedule myelosuppression is modest. The recommended phase II doses are docetaxel 35 mg/m(2) and irinotecan 60 mg/m(2) on days 1 and 8 of a 21-day schedule. Phase II trials of this regimen are ongoing or planned in lung, head and neck, stomach, esophageal, and pancreatic cancers.

Although various combinations of chemotherapy regimens have been tried for patients with esophageal cancer, their duration of survival is extremely poor. In this study, we investigated the safety and clinical efficacy of paclitaxel and cisplatin chemotherapy in metastatic or recurrent esophageal cancer. 32 patients enrolled in this study and the median age was 60 yr. Of all the 32, 28 patients (88%) had been treated previously, 22 of them with chemotherapy or radiation therapy. All patients in the study received biweekly paclitaxel (90 mg/m(2)) followed by cisplatin (50 mg/m(2)). One patient (3%) responded completely, and 12 patients (38%) showed a partial response; in 9 patients (28%) the disease remained stable, and in 10 patients (31%) it progressed. The objective response rate was 41%. The median duration of response was 4.8 months, and the median overall survival in all patients was 7 months. The 1-yr and 2-yr survival rates were 28.1% and 7.1%, respectively. Grade 3 or 4 of neutropenia and anemia were observed in 6 (19%) and 5 (16%) patients, respectively. The major non-hematologic toxicity was fatigue, but most of them could manageable. In conclusion, biweekly paclitaxel and cisplatin is effective in patients with metastatic or recurrent esophageal cancer.

An 80-year-old woman with advanced cervical esophageal cancer underwent chemoradiotherapy with docetaxel/5-FU/CDDP (DFP). The tumor reduced in size after the treatment,but severe pancytopenia and scar stenosis of cervical esophagus appeared. In consideration of her age,the treatment was changed to the administration of UFT alone on an outpatient basis. Ten months after the medication, a follow-up CT scan showed multiple lung metastases and mediastinal lymph node metastases. The patient was treated with DFP therapy again, and all tumors reduced in size, but severe general fatigue and pancytopenia appeared during this therapy. Given the difficulty of continuing this therapy, the treatment was changed to UFT alone on an outpatient basis. The followup CT scan showed a reduction in the size of all tumors even 8 months after discharge. UFT alone appears to be safe and effective as maintenance therapy after DFP therapy, especially for elderly patients.
