This represented 10.2% of all treated cases with esophageal carcinoma during the same period. The mean age was 63 years. The most common symptom was dysphagia. According to PTNM staging, 18 were stage II,3 stage III and 3 stage IV. All patients were treated bysurgery. The 30-day hospital mortality was 3.98%. Theone, two and five-year survival rates were 45.9%, 25.0%and 13.6%, respectively. The 5-year survival rate wassignificantly greater for patrents with stage II (25.0%)than for parients with stage III + IV (4.s%) (P<0.05) andfor tumor length less than 6 cm (21%) than for tumorlength greater than 6 cm (0). The results indicate that thesurvival rate following resection is closely related to theclinical stage and tumor size.展开更多

We present a case of synchronous double primary cancer of trachea and esophagus in a 70-year-old woman, with a special symptom of ventricular tachycardia and no/a/story of smoking and alcohol drinking. Biopsies （tom multiple loci demonstrated the patient had primary small cell cancer of trachea and squamous cell carcinoma in situ of esophagus. The patient was successfully treated with four cycles of chemotherapy consisting of etoposide and earboplatin （EC） followed by thoracic radiotherapy （60 Gy in 30 fractions, in 6 weeks）, and was evaluated to have complete response of tumor. To our knowledge, there is no synchronous cancer of trachea and esophagus has been reported in English literature, and our experience showed sequential EC chemotherapy and radiotherapy provided an effective treatment to control both cancers.展开更多

The different depth of tumor invasion including EP, MM and SM cancers showed significant differences in the 5-year survival rate (P < 0.05), Although the prognosis for the patients with lymph node metastasis is poor, we should advocate extended lymph node dissection in surgical treatment of the patients in whom MM and SM cancers are suspected.展开更多

Methods The archival materials of 763 cases of esophageal malignancies (1977 1996) from the Dept. of Pathology, General Hospital of Nanjing Military Region, PLA, were reviewed and sixteen cases (2.1%) of BSC were detected. The clinical and pathological features of these cases were evaluated. Immunohistochemistry (S P method), histochemical staining, and electron microscope were utilized to further characterize the neoplasm. Results There were 9 males and 7 females, with a mean age of 58 years. The tumors were classified as stage Ⅰ (n=1), stage ⅡA (n=6), stage ⅡB (n=2), stage Ⅲ (n=5), and stage Ⅳ (n=2) according to the criteria of the UICC TNM classification system of malignant tumors (1987). Most neoplasms in our series were located in the middle third of the esophagus. Grossly, they had an appearance similar to that of conventional esophageal carcinoma. Histologically, they showed a typical cytoarchitectural pattern of BSC. The most important histologic feature of this tumor was that the carcinoma had a basaloid pattern, intimately associated with squamous cell carcinoma, dysplasia, or focal squamous differentiation. The basaloid cells were round or oval in shape with scant cytoplasm. The nuclei showed pleomorphism, hyperchromatin, and numerous mitotic figures. The basaloid cells were arranged mainly in the form of solid, smooth contoured lobules with peripheral palisading. Comedo necrosis in the islands of basaloid cells, small cystic spaces containing Alcian blue or PAS positive material, and PAS positive hyalinized stroma were frequently found. A panel of immunostains were used for the basaloid component of the tumor with the following results: cytokeratin (Pan),14/16 (+); epithelial membrane antigen, 16/16 (+); Vimentin, 4/16 (+); S 100 protein, 7/16 (+). Carcinoembryonic antigen and smooth muscle actin were negative. Electron microscopic (EM) study of 7 cases revealed that the basaloid cells are poorly differentiated, with a few desmosomes and fibrils and numerous free and polyribosome. The microcystic and intertrabecular spaces identified by light microscopy were seen under EM to be lined by basal membranes and filled with either loose reduplicated or compact globoid basal lamina showing fingerprint like pattern. Of the 11 cases with adequate follow up, 8 cases died within 2 years, the average survival time being 16.2 months. No cases of stages Ⅱ, Ⅲ, or Ⅳ survived beyond 5 years. The one year survival rate was 60% and two year 20%. Conclusion It is indicated that the BSC of the esophagus is a distinct clinicopathological entity with poor prognosis. The cellular differentiation and biologic behavior of the esophageal BSC were assumed to be situated between those of conventional squamous cell carcinoma and small cell carcinoma.展开更多

The diagnosis of all 11 cases was confirmed by bariummeal roentgenography. After intubation, all the patients could take liquid or soft diet by mouth.There was no operative mortality and the patients survived 2 to 14 months (mean5.7 months). All of them could take food by mouth before death. The clinical application proved that the intubation has been a safe and suitable management.展开更多
