1/42. Complete response of a gastric primary after a short but toxic course of 'S-1' EORTC Early Clinical Studies Group.We report the case of an unresected, metastatic gastric cancer, which was treated with a very short course of the oral 5-fluorouracil (5-FU) prodrug S-1. The patient had to discontinue chemotherapy during the first treatment cycle due to severe toxicity, but achieved a pathologically confirmed, long-term complete response of her primary tumour, a diffuse-type poorly differentiated adenocarcinoma.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
2/42. Multiple tumors and a novel E2F-4 mutation. A case report.Defects in the dna mismatch-repair are known to cause microsatellite instability (MSI) in hereditary nonpolyposis colorectal cancer (HNPCC) as well as sporadic colorectal cancer (CRC). We previously reported that the E2F-4 gene, which encodes an important transcription factor in cell cycle control, had frequent tumor-specific mutations at the trinucleotide coding region microsatellite (CAG)n in a subset of human sporadic CRC with MSI. We report a 65-year-old man with triple tumors in the abdomen, including colon cancer, stomach cancer, and lipoma of the retroperitoneum, with the analysis of E2F-4 mutation. We report the first case of colon cancer with a homozygous E2F-4 mutation along with a detailed analysis of other cancer related genes as well as a prognosis.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
3/42. Metastatic tumour of the tunica vaginalis testis from carcinoma of the stomach.A 50-year-old man with advanced inoperable gastric adenocarcinoma and diffuse peritoneal metastasis received six cycles of palliative chemotherapy and responded clinically with weight gain. Two months after the completion of chemotherapy, however, he developed a left hydrocele. Aspiration yielded 70 ml of yellowish hydrocele fluid, which contained metastatic adenocarcinoma cells, consistent with a gastric primary tumour. A diagnosis of malignant hydrocele was made. Two weeks later, he developed a painful recurrent left hydrocele with increasing pain and swelling. Left orchidectomy was performed. Tiny white mural nodules measuring 1 mm in size were noted on the tunica vaginalis. No focal lesion was noted in the testis. On microscopic examination, the tunica vaginalis showed reactive mesothelial hyperplasia and extensive lymphatic permeation by poorly differentiated adenocarcinoma, consistent with a gastric primary tumour.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
4/42. Synchronous gastric adenocarcinoma and MALT lymphoma in a patient with H. pylori infection. Could the two neoplasms share a common pathogenesis?Low-grade primary MALT (mucosa-associated lymphoid tissue) lymphoma of the stomach is a neoplasm with an indolent course and a good prognosis. patients with this type of neoplasm seem to have a higher risk for other neoplasms. Of interest is the association of gastric MALT lymphoma with gastric adenocarcinoma of intestinal type. We report the case of a patient, with a history of H. pylori-related gastritis, in whom a diagnosis of synchronous gastric adenocarcinoma of intestinal type and low-grade MALT lymphoma, occurring as collision tumors, was made. The stage procedures confirmed the presence of a locally advanced gastric tumor staged as T3 N1. The patient underwent two cycles of neoadjuvant EEP (etoposide, epirubicin, cisplatin) chemotherapy. After 2 months, a R0 total gastrectomy with D2-lymphoadenectomy was successfully performed. The development of simultaneous primary gastric lymphoma and carcinoma is a rare event. The possible coexistence of both tumors should be kept in mind, especially in patients infected with H. pylori, since a possible etiopathogenetic role of this bacterium has been differently postulated for both disease.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
5/42. Spontaneous acute tumor lysis syndrome with advanced gastric cancer.Acute tumor lysis syndrome (TLS) occurs frequently in hematologic malignancies such as high-grade lymphomas and acute leukemia, which are rapidly proliferating and chemosensitive tumors. It occurs rarely in solid tumors and has never been reported in gastric adenocarcinoma. Typical biochemical findings of acute tumor lysis syndrome are hyperuricemia, hyperkalemia, hyperphosphatemia and hypocalcemia in patients with a malignancy. Rapid changes of these electrolytes may cause cardiac arrhythmia, seizure, acute renal failure and sudden death. Therefore, as soon as it is detected, it should be taken care of immediately. Until now almost all cases of TLS associated with solid tumor have developed after cytoreductive therapy in chemosensitive tumors. We report here a case of spontaneous acute tumor lysis in a patient of advanced gastric cancer with hepatic metastases and multiple lymphadenopathy. The biochemical finding of TLS improved with the management and tumor burden also showed slight response to the one cycled combination chemotherapy but the patient died of progressive pneumonia.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
6/42. Complete response of an hiv negative gastric Kaposi's sarcoma (KS) patient with peritoneal carcinomatosis by liposomal daunorubicin treatment.We report the first case of an hiv negative patient with gastric Kaposi's sarcoma (KS) and peritoneal carcinomatosis in whom a complete response (CR) was obtained after liposomal daunorubicin administration. The patient presented with epigastric pain and hematemesis. Upper gastric endoscopy with multiple biopsies showed gastric involvement by KS. The whole physical examination and the thoraco-abdomino-pelvic CT scans showed no other localization. A total gastrectomy was performed. Histological examination confirmed the diagnosis of KS with involvement of regional lymph nodes and peritoneal lesions. Six cycles of liposomal daunorubicin were given. Post-treatment coelioscopic control was normal. The patient received another six adjuvant cycles of liposomal daunorubicin. The patient is in complete remission six months after the end of treatment. Liposomal daunorubicin is a promising treatment in the non hiv patient with visceral KS.- - - - - - - - - - ranking = 2keywords = cycle (Clic here for more details about this article) |
7/42. Advanced gastric cancer with multiple lymph node metastasis successfully treated with etoposide, adriamycin and cisplatin.Gastric cancer usually shows poor sensitivity to chemotherapy, and the presence of lymph node metastases is associated with extremely poor prognosis, especially when the number of such nodes is more than 10. We report here a case of advanced gastric cancer with histopathologically confirmed metastases in 15 regional lymph nodes, in which the recurrent tumor was sensitive to combination chemotherapy. Distal gastrectomy with lymphadenectomy was performed for the primary tumor. A hard (recurrent) tumor was detected in the upper abdomen 5 months postoperatively. Abdominal CT revealed two tumors measuring 3.5 x 1.8 and 3.3 x 2 cm in diameter at the front of the pancreatic head, which suggested recurrence. etoposide, adriamycin and cisplatin (EAP) chemotherapy (20 mg/kg adriamycin, 100 mg/kg etoposide and 50 mg/kg cisplatin (CDDP)) was administered every 6 weeks. The tumors regressed and became undetectable on CT after four cycles. At that stage, CDDP was replaced with 400 mg/kg carboplatin, which was administered every 1 or 2 months. The patient had no recurrence 8 years after surgery. For treatment of advanced gastric cancer with multiple lymph node metastases, a wide resection of the tumor should be performed followed by treatment of the residual tumor cells with a suitable combination chemotherapy taking into consideration the characteristics of the tumor and the condition of the host. We present a patient with gastric cancer and histopathologically confirmed metastases in 15 regional lymph nodes, who was successfully treated by surgery followed by EAP adjuvant chemotherapy. The patient remains alive and well at 8 years after surgery.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
8/42. Complete response of highly advanced gastric cancer with peritoneal dissemination after new combined chemotherapy of S-1 and low-dose cisplatin: report of a case.TS-1(S-1) has been developed as a new oral anticancer drug based on the biological modulation of 5-fluorouracil. We treated a patient with highly advanced gastric carcinoma with a new combination chemotherapy of S-1 and low-dose cisplatin. Remarkable tumor reduction was observed after two cycles of this therapy in the primary tumor and metastatic lymph nodes, and the ascites disappeared. This was concluded to be a partial response. The only adverse effect was skin pigmentation of the fingers (grade 1), leading to early timing of operation after chemotherapy. The gastric tumor showed evident invasion to the serosa. lymph nodes around the stomach were swollen. Peritoneal dissemination was also recognized in the omentum and mesocolon. Total gastrectomy with regional lymph node dissection was performed. Disseminated tumors were all resected. Histological examination showed that no tumor cells were detected in the gastric primary lesion, metastatic lymph nodes or disseminated peritoneal tumors, suggesting pathological complete remission. It was suggested that this regimen could be a potent combined therapy for the treatment of patients with highly advanced gastric carcinoma, and it could be useful as neoadjuvant chemotherapy. Further studies are necessary to evaluate the efficacy of this therapy.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
9/42. Primary gastric choriocarcinoma: a case report and review of the literature.choriocarcinoma is a rapidly invasive, widely metastatic human chorionic gonadotropin (HCG)-producing neoplasm, usually intrauterine and gestational. Primary gastric choriocarcinoma is very rare, and its pathogenesis is still uncertain. We report a case of primary gastric choriocarcinoma associated with adenocarcinoma in a 36-year-old woman. The patient presented with gastrointestinal bleeding and a gastric mass clinically suspicious of gastric adenocarcinoma. Histopathologic evaluation proved the tumor to be a choriocarcinoma, with a minor component of a poorly differentiated adenocarcinoma. The patient was treated with a standard nongestational choriocarcinoma chemotherapy regimen. An impressive initial response was evidenced by clinical reduction of the tumor volume and drop of the serum beta-HCG levels after the first cycle. However, the tumor rapidly recurred in the abdomen and disseminated to the lungs, which were documented by new elevation of serum beta-HCG levels and computed tomographic scans despite continuing with 3 more cycles of chemotherapy. The patient died 6 months after diagnosis.- - - - - - - - - - ranking = 2keywords = cycle (Clic here for more details about this article) |
10/42. Advanced gastric cancer associated with DIC successfully treated with 5-FU and cisplatin: a case report.We report a case of advanced gastric cancer complicated by disseminated intravascular coagulation successfully treated with chemotherapy consisting of 5-fluorouracil and cisplatin. The patient was a 53-year-old woman who complained of loss of appetite, weight loss, and low back pain. Based on the laboratory data, a diagnosis of disseminated intravascular coagulation was made. gastroscopy revealed gastric carcinoma (Borrmann type 3) that was continuously bleeding, and chest computed tomography showed a solitary lung metastasis and bilateral pleural effusion. Bone scintigraphy revealed multiple bone metastases. Accordingly, we made a diagnosis of stage IV gastric cancer complicated by disseminated intravascular coagulation. We selected the 5-fluorouracil and cisplatin combination chemotherapy for treatment and obtained the patient's consent. After two cycles of the 5-fluorouracil and cisplatin therapy, the bleeding symptoms improved and the disseminated intravascular coagulation process was successfully controlled. We concluded that disseminated intravascular coagulation caused by gastric cancer may be improved when the primary cancer and its metastases are brought under control by treatment with FP combination chemotherapy.- - - - - - - - - - ranking = 1keywords = cycle (Clic here for more details about this article) |
