Abstract

We report a case of a 74-year-old man with a cluster of differentiation (CD) 7-positive diffuse large B-cell lymphoma (DLBCL) in the right nasal cavity. Flow cytometry analyses showed CD7 and CD20 positivity in tumor cells. The patient received 6 cycles of R-CHOP plus local radiation therapy because positron emission tomography-computed tomography after R-CHOP revealed an intranasal lesion. The patient achieved complete remission (CR) after radiation therapy. The frequency of CD7-positive DLBCL is rare, and only 11 cases with follow-up of clinical course have been reported thus far. CR or partial response was noted in 8 of 11 cases after receiving rituximab combined with chemotherapy. In total, 9 of 12 cases involved the development of extranodal lesions, which occurred as an intranasal tumor in 3 cases. It is important to examine the clinical features by accumulation of further cases.

Abstract

A 58-year-old woman was admitted to our hospital for evaluation of left flank pain. Abdominal computed tomography showed a greatly enlarged splenic tumor with a massive portal vein tumor thrombosis (PVTT). We suspected non-Hodgkin lymphoma (NHL) based on the high values of serum soluble interleukin-2 receptor and lactate dehydrogenase. Because there was no superficial lymph node enlargement, ultrasound-guided percutaneous trans-hepatic needle biopsy was performed to obtain a pathological diagnosis of PVTT, instead of a splenectomy, after the patient had provided informed consent. This procedure was thought to be less invasive than splenectomy. Histologic examination revealed CD20-positive NHL. A complete response was achieved after six courses of R-CHOP and it was confirmed by splenectomy. A PVTT due to NHL is extremely rare as compared with that due to hepatocellular carcinoma, gastric cancer, and colon cancer. However, NHL should be considered in the differential diagnosis for a patient with a PVTT, because B cell-NHL tends to have a good prognosis when rituximab combined chemotherapy is administered. We suggest that a percutaneous trans-hepatic needle biopsy may be useful for diagnosing PVTT due to NHL.

Abstract

Background: Definitive chemoradiotherapy (dCRT) has been established as the standard treatment for esophageal squamous cell carcinoma (ESCC). However, many patients develop persistent or recurrent disease following dCRT. We investigated factors related to chemoradioresistance and treatment outcomes in patients with ESCC who underwent salvage esophagectomy after dCRT., Patients and Methods: We selected 38 patients with persistent disease and 24 with recurrent disease who underwent salvage esophagectomy after dCRT, immunolocalized p53, p16, p27, murine double minute 2 (MDM2), cyclin D1, Ki-67, and epidermal growth factor receptor, and correlated the findings with clinicopathological features., Results: MDM2 positivity was significantly higher among patients with persistent disease than among those with recurrent disease (p<0.0001). In addition, negative p16 expression was a predictor of poor prognosis among patients with persistent disease., Conclusion: MDM2 overexpression plays an important role in chemoradioresistance of ESCC; furthermore, negative p16 expression can predict poor prognosis of patients with persistent disease.
