Introduction:Cardiac involvement as an initial presentation of malignant lymphoma has been a rare occurrence.Case Presentation:We have reported a 78 year old man with complaint of abdominal pain and vomiting. In patients preoperative evaluation for surgical management of an intra-abdominal mass, a large intracardiac mass has found incidentally during the echocardiography. Pathologic biopsy of right atrial mass that has removed by open heart surgery shown: non Hodgkin-B cell lymphoma. Bone marrow biopsy was taken and was positive for lymphomatous involvement.Conclusions:The patient has treated by CHOP chemotherapy regiment successfully and after completion of treatment, there was complete response.

IntroductionNo standard method has been defined to evaluate the therapeutic response of esophageal cancer to neoadjuvant chemoradiotherapy (CRT). This study aimed to determine the predictive value of endoscopic evaluation and biopsy after CRT in predicting the complete pathological response to neoadjuvant CRT in patients with esophageal squamous cell carcinoma (SCC).Materials and MethodThis prospective, descriptive study was conducted on patients with stage II and III esophageal SCC who could undergo esophagectomy. Patients underwent neoadjuvant CRT. Four to six weeks after the end of treatment, re-endoscopy was performed and a biopsy was taken in the presence of a tumor lesion. In the absence of a tumor lesion, the marked site of the esophagus was removed as a blind biopsy. Gastrologist observations during endoscopy and the result of the pathological examination of an endoscopic biopsy were recorded. The patient underwent esophagectomy. The pathology obtained from endoscopic biopsy was compared with the pathology response obtained from esophagectomy.ResultsSixty-nine patients were included in the study, of which 32 underwent esophagectomy. In an endoscopic examination after CRT, 28 patients had macroscopic tumor remnants and 4 patients did not. Pathological examination of the samples obtained from endoscopy showed no tumor remnants in 10 patients (31.3%), and in 22 patients (68.7%), living tumor remnants were seen in the biopsy specimen. Pathologic evaluation of the samples obtained by surgical resection showed that in 13 patients, there were no viable carcinomas in the esophagus or lymph nodes removed, and the rate of pathologic complete response was 40.6. Sensitivity, specificity, positive predictive, and negative predictive values of endoscopic observations were 94.7, 23, 64.2, and 75%, respectively. Preoperative biopsy sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were 68.4, 30.7, 59, and 40%, respectively.ConclusionConsidering the negative and positive predictive values of endoscopic observations and biopsy after neoadjuvant CRT, it seems that these two methods alone are not suitable for assessing the pathologic complete response after neoadjuvant treatment.

Background: Preoperative concurrent chemoradiotherapy may improve surgical results and patient survival rates in gastric adenocarcinomas. We aimed to assess tumor resectability and pathologic response rates in patients with locally advanced proximal gastric and esophagogastric junction adenocarcinomas by preoperative CRT and toxicity evaluation of treatment.
