1/1326. The effectiveness of chemotherapy with cisplatin and 5-fluorouracil for recurrent small cell neuroendocrine carcinoma of the rectum: report of a case.We report herein the case of a 46-year-old-man with small cell neuroendocrine carcinoma (NEC) concomitant with large villous adenoma of the rectum, who underwent abdominoperineal resection with regional lymphnode dissection. The resected specimen was histologically found to contain a small lesion of NEC confined to the submucosa in the large adenoma. A computed tomography scan done 4 months postoperatively revealed recurrences in the liver, lymph nodes, and bone. Therefore, two cycles of sequential intravenous combined chemotherapy with standard doses of cisplatin and 5-fluorouracil (5-FU) were administered, after which the size of each tumor decreased remarkably. Nevertheless, the patient died 8 months after the operation. As there was a fair response of this tumor to the combined chemotherapy of cisplatin and 5-FU, this regimen against NEC of the colon and rectum should be given consideration.- - - - - - - - - - ranking = 1keywords = carcinoma (Clic here for more details about this article) |
2/1326. Small cell lung cancer accompanied by lactic acidosis and syndrome of inappropriate secretion of antidiuretic hormone.Lactic acidosis is a rare complication in lung cancer. We report a case of lung cancer accompanied by both syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and lactic acidosis. A 70-year-old man was referred to our hospital for examination of a left hilar mass shadow on a chest x-ray film. Small cell lung cancer (SCLC) was demonstrated by brushing the bronchial mucosa of the left lower lobe bronchus. His laboratory data showed SIADH and lactic acidosis that were probably due to SCLC. Fluid restriction improved SIADH, and combination chemotherapy for SCLC improved the lactic acidosis although the tumor size did not change.- - - - - - - - - - ranking = 1.7092738700724keywords = cell lung, cell lung cancer, lung cancer, lung, cancer (Clic here for more details about this article) |
3/1326. A case of long-term survival with stage IV small cell lung cancer and early-stage central-type squamous cell lung cancer treated by photodynamic therapy.The present report is on a 67-year-old man with stage IV small cell lung cancer and early-stage centrally located squamous cell cancer of the lung. He was diagnosed as small cell lung cancer with multiple metastasis to the ipsilateral lung and was found to have a central-type early-stage squamous cell cancer by bronchoscope. After obtaining a complete response to the small cell lung cancer with chemotherapy and radiotherapy, photodynamic therapy was applied to the squamous cell carcinoma, resulting in complete disappearance of the tumor. recurrence of small cell cancer occurred at the ipsilateral lung and this patient died of small cell cancer 8 years after initiation of treatment. Post mortem examination confirmed complete disappearance of squamous cell cancer treated by photodynamic therapy. This is a rare case of long-term survival with stage IV small cell lung cancer and early-stage central-type squamous cell lung cancer successfully treated by photodynamic therapy.- - - - - - - - - - ranking = 4.5700269662908keywords = carcinoma, cell lung, cell lung cancer, lung cancer, lung, cancer (Clic here for more details about this article) |
4/1326. Extended radical resection for bulky N2 small cell lung carcinoma.In three patients with bulky N2 small cell lung carcinomas who received chemotherapy, complete clinical remission at the N2 site was obtained. Extended radical resection including mediastinal lymph node dissection was performed on these three patients, followed by postoperative chemotherapy. Combined resected organs were azygos vein, superior caval vein, and left atrium. We obtained good results with the patients surviving 104, 53, and 38 months respectively, after the initial therapy.- - - - - - - - - - ranking = 2.2542352448571keywords = carcinoma, cell lung, lung carcinoma, lung (Clic here for more details about this article) |
5/1326. Metastasis-induced acute pancreatitis in a patient with small cell carcinoma of the lung.Acute pancreatitis in cancer patients can be secondary to the malignant process itself or a complication of antineoplastic agent administration. However, acute pancreatitis caused by metastatic carcinoma of the pancreas is an uncommon condition with a poor prognosis. We report a case of a 63-year-old man with small cell carcinoma of the lung, who developed acute pancreatitis lately. Thirteen months earlier, he developed small cell carcinoma of the lung and received 6 cycles of chemotherapy. Abdominal CT scan showed swelling of the pancreas with multiple masses. The patient was managed conservatively and pancreatitis subsided. This case indicates that metastasis induced acute pancreatitis can be a manifestation of lung cancer, especially in small cell carcinoma.- - - - - - - - - - ranking = 1.647987839706keywords = carcinoma, lung cancer, lung, cancer (Clic here for more details about this article) |
6/1326. Small-cell carcinoma of the rectum: report of two cases.Small-cell carcinoma of the rectum is an infrequent pathologic finding, and its precise incidence is unknown. Its incidence is less than 0.2 percent among all colorectal cancers. This tumor manifests highly aggressive behavior. The treatment of choice is combination chemotherapy similar to that used for small-cell carcinoma of the lung, but in small localized tumors surgery plus chemotherapy is an alternative. We present two cases of small-cell carcinoma of the lower rectum and a review of the literature.- - - - - - - - - - ranking = 1.4053277837088keywords = carcinoma, lung, cancer (Clic here for more details about this article) |
7/1326. Pulmonary small cell carcinoma associated with sarcoid reactions: report of a case.A 45-year-old male was admitted to our hospital for investigation of a nodular shadow in segment 5 of the right lung on a chest computed tomogram. A right middle lobectomy with mediastinal lymph node dissection was performed under a diagnosis of lung cancer, and histologic examination confirmed small cell carcinoma. There were sarcoid reactions in the resected lymph nodes and the lung parenchyma, but no signs of systemic sarcoidosis were evident. Sarcoid reactions are rarely observed in the regional lymph nodes draining malignant tumors. Moreover, while they are most common in squamous cell carcinoma of the lung, they extremely rare in small cell carcinoma. To our knowledge, this is only the third report of this unusual entity in the English and Japanese literature.- - - - - - - - - - ranking = 1.4325676996019keywords = carcinoma, lung cancer, lung, cancer (Clic here for more details about this article) |
8/1326. Special problems in cervical cancer management.Cervical cancer is easily recognized when it presents as a visible lesion, but a problem arises when it adopts unusual presentations. Cervical cancer can develop high in the endocervical canal, beyond the reach of cone biopsy. Copious vaginal discharge from cervical adenocarcinoma may lead to a false-negative Papanicolaou (Pap) smear. Treatment of cervicitis can result in a delay in diagnosis. Successful and timely diagnosis and treatment of cervical cancer requires experience and vigilance. Careful intraoperative palpation of the cervix and uterus can help determine the location and extent of the lesion. Flexibility during surgery is required to utilize intraoperative findings and thus optimize treatment. Pitfalls of cervical cancer diagnosis and treatment with actual case presentations are presented along with other special problems in cervical cancer management such as incidental findings of cervical cancer in hysterectomy specimens, treatment of cervical stump cancers, and unusual cervical cancer cell types.- - - - - - - - - - ranking = 0.20337926613349keywords = carcinoma, cancer (Clic here for more details about this article) |
9/1326. Primary advanced gastric small cell carcinoma: a case report and review of the literature.We report a 73-yr-old man with primary advanced gastric small cell carcinoma, pure type. A large, Borrman type I tumor was located from the cardia to the entire gastric fundus and upper body. Atypical cells showed a round nucleus, small nucleolus, dense to granular chromatin, and scant cytoplasm. The histological findings indicates an advanced stage and exposure to the gastric serosa. Mitotic figures were observed. There was a proliferation of a sheet-like, solid pattern, but no rosette-like, sqamoid, or glandular patterns. The neoplastic cells were positive for Leu-7 (CD57) and 123C3 (CD56, neural cell adhesion molecule, NCAM) on the surface membrane. We diagnosed this case as primary advanced gastric small cell carcinoma, pure type, and report that Leu-7 and 123C3 monoclonal antibodies are useful markers for gastric small cell carcinoma. The 32 previously reported cases of gastric small cell carcinoma are also reviewed.- - - - - - - - - - ranking = 1.6keywords = carcinoma (Clic here for more details about this article) |
10/1326. Small cell carcinocythemia.Tumor cells circulate in the blood, but it is unusual to find cancer cells on a routine peripheral smear. The term carcinocythemia is used to describe this phenomenon. Four patients have been reported previously with small cell lung cancer and carcinocythemia. A fifth case is described in this article. These patients presented with advanced disease and had generalized lymphadenopathy and liver involvement; 3 had splenic metastases. All of these patients experienced rapid clinical deterioration. death occurred 3 days to 2 weeks from the time carcinocythemia was detected. The presence of small cell carcinocythemia can be one of the manifestations of end-stage disease and is associated with an extremely poor prognosis.- - - - - - - - - - ranking = 0.33516471352206keywords = cell lung, cell lung cancer, lung cancer, lung, cancer (Clic here for more details about this article) |
