The clinical and pathologic data of 311 cases of primary GIST, including 257 cases with clinical GIST and 54 cases of incidental GIST were analyzed.RESULTS: Of the 311 patients, 54 had incidental GIST, accounting for 17.4%. Of these tumors, 27 were found in 1.13% patients with esophageal squamous cell carcinoma (ESCC), 22 in 0.53% patients with gastric adenocarcinoma (GAC), 2 in 0.38% patients with PAC, 2 in 0.03% patients with colorectal adenocarcinoma, and 1 in one patient with GAC accompanying ESCC, respectively. Patients with incidental GIST presented symptoms indistinguishable from those with EMT. All incidental GIST lesions were small in size, and the majority had a low mitotic activity while only 1.9% (5/257) of clinical GIST lesions had a high risk.CONCLUSION: Incidental GIST may occur synchronously with other tumors and has a high prevalence in males. Surgery is its best treatment modality.展开更多

Due to the recent developments in diagnostic techniques and instrumentation, the early detection of gastric carcinoma (GC) has increased. Yet synchronous multiple primary gastric carcinomas, de- fined as 2 or more primary gastric carcinomas occurring in 1 patient simultaneously, are not frequently seen. The etiology of synchronous tumors is still unclear, and their coexistence can be problematic for surgeons, oncologists and pathologists in regards to diagnosis, treat- ment, and follow-up. Research has focused mainly on such issues as the frequency of occurrence of primary multiple carcinomas, identi- fication of high-risk groups, early diagnosis, treatment methods, and prognostic factors. The purpose of this article is to present a rare case of synchronous tumors and to review the literature addressing the surgical treatment for patients with multiple cancers.展开更多

Methods: Fifty-six cases with cervical cancer (FIGO lib to IVa) were divided randomly into two groups in the oncology hospital of Jingzhou from September 2009 to October 2010, radiotherapy alone (28 cases) and radiation plus chemotherapy (TP) group. There was no difference of radiotherapy between the two groups, the RT + C cases who accepted TP regimen during the radiation, and DDP once weekly injection of vain, according to 20 mg/m2 and taxotere once weekly i.v. according to 35 mg/m2. These regimen were given for 4-5 weeks, and some medicine for vomit- ing was given to the RT + C cases. Two groups were received an oral medicine MA 160 mg every day during the treatment. Results: The early outcome: the complete remission rate was 64.3% and partial remission rate was 35.7% in RT + C. The complete remission rate was 32.1% and partial remission rate was 39.3% in RT. The total response rate and complete remis- sion of RT + C group was higher than that of the RT group. There was significant difference between the two groups. In RT + C group, 1-year survive rate was 100.00% (28/28); in RT group, 1-year survive rate was 85.71% (24/28). There was significant difference between the two groups (X2 = 4.31 〉 3.84, P 〈 0.05). Conclusion: The taxotere and cisplatin chemoradiotherapy can improve the early outcome of the advanced cervical cancer, and the adverse effect are raised, but that can be endured.展开更多
