Abstract
BACKGROUND Primary intestinal extranodal natural killer/T-cell lymphoma, nasal type (PI-ENKTCL) is a rare non-Hodgkin’s lymphoma (NHL) subtype, and its prognosis is extremely poor. Clinical characteristics of the disease are not obvious and easily misdiagnosed. In this case report, we describe a patient with PI-ENKTCL who presented with intermittent hematochezia. The advantages of positron emission tomography/computed tomography (PET-CT) as a useful diagnostic tool and the role of surgery as an important therapy are highlighted.
CASE SUMMARY A 45-year-old man, hospitalized due to intermittent hematochezia, underwent gastroscopy, colonoscopy, biopsy and CT, but no cause was found. Hence, we carried out a multidisciplinary team (MDT) discussion on the causes and treatment of this patient, and it was decided to perform PET-CT imaging with a MDT discussion of the results. PET-CT demonstrated a diagnosis of lymphoma and it was decided to surgically resect the lesion, and a R0 resection was successfully performed. Postoperative pathology showed negative resection margins, and examination of the lesion confirmed the diagnosis of PI-ENKTCL. After surgery, the patient underwent a follow-up period of 6 mo and received 6 cycles of gemcitabine, oxaliplatin and L-asparaginase. No recurrence or metastasis occurred.
CONCLUSION PI-ENKTCL is rare, and MDT discussion is required during diagnosis. PET-CT can be performed for imaging diagnosis. Treatment is based on surgical resection, and the best treatment regimen is determined according to postoperative pathological results to improve prognosis and to extend survival in patients.

Abstract
BACKGROUND The gastrointestinal tract is the most common primary site of extranodal lymphomas, whereas gastrointestinal natural killer/T-cell (GINKT) lymphomas are relatively rare. To date, neither the prognostic characteristics nor the clinical features or optimal therapeutic approach for GINKT has yet been defined. PATIENTS AND METHODS In this study, a retrospective analysis was carried out on clinical data obtained from 47 patients diagnosed with GINKT lymphoma between May 1999 and August 2011 at West China Hospital. RESULTS Patients had a median age of 37 years. Thirty-five of the patients were men (74.5%). The common clinical manifestations included fever (78.7%) and abdominal pain (76.6%). Seventeen patients had intestinal perforation (36.2%). All patients showed ulcerative lesions; the most common site of involvement was the colon (27/47; 57.4%), followed by the jejunoileum and ileocecum (14/47; 29.8%). The median survival period was 2.83 (95% confidence interval, 0.27-29) months. Age, perforation, B syndrome, staging according to Lugano system, and surgery were independent prognostic risk factors for GINKT lymphoma. CONCLUSIONS This study concluded that GINKT lymphoma is prone to perforation, hemorrhage, and other complications; moreover, the prognosis is very poor. The Lugano staging is a relatively suitable staging system. Surgery before perforation is a key therapy factor that affected prognosis. Although the roles played by chemotherapy and radiotherapy are unclear, combination therapy is necessary.

Abstract
In China, which is a non-endemic area for celiac disease, primary intestinal T-cell and NK-cell lymphomas might comprise heterogeneous subtypes. Both type II enteropathy-associated T-cell lymphoma and primary intestinal NK-cell lymphoma are rarely reported and poorly characterized in China. In this study, we examined the clinicopathological and molecular features of 38 cases of primary intestinal T-cell and NK-cell lymphoma in Chinese patients. Based on these findings, we first classified the patients into an NK-cell group (n=6) and a T-cell group (n=32). In the NK-cell group, the mean age was 37 years. All tumors of the NK-cell group were positive for Epstein-Barr virus encoded mRNA in the majority of tumor cells and were polyclonal according to the results of commercial BIOMED-2 T-cell receptor gene rearrangement assays. The survival in the NK-cell group was significantly worse than that of the T-cell group (P=0.0247). Next, 7 tumors of the T-cell group were considered type II enteropathy-associated T-cell lymphoma, while 24 were considered peripheral T-cell lymphoma, not otherwise specified (NOS). In the type II enteropathy-associated T-cell lymphoma group, the mean age was 55 years. Type II enteropathy-associated T-cell lymphoma tumor cells from all seven patients were monomorphic, medium sized. The survival in the type II enteropathy-associated T-cell lymphoma group was significantly worse than that of the peripheral T-cell lymphoma, NOS group (P=0.0181). Multivariate analysis identified NK-cell phenotype, male gender, and CD8 positivity as factors for poor prognosis in our series of primary intestinal T-cell and NK-cell lymphoma patients. In conclusion, most cases of primary intestinal T-cell and NK-cell lymphoma in China are not associated with celiac disease and could be classified to NK-cell group, type II enteropathy-associated T-cell lymphoma group, and peripheral T-cell lymphoma, NOS group. Each group has distinctive histopathological features with prognostic significance.

Abstract
Extranodal NK/T-cell lymphoma (ENKL), nasal type, is rare and the small intestine is quite extraordinary as a primary lesion site. We report a 47-year-old man with ENKL of the small intestine. He was referred to our hospital because of bloody stool and the diagnosis was made by double-balloon endoscopy (DBE) of the small intestine without surgical procedure. His clinical stage was IVB and he was categorized in group 4 by prognostic index of ENKL. He went into complete remission (CR) after intensive chemotherapy (DeVIC) and subsequently underwent allogeneic bone marrow transplantation (BMT). Although he remained in CR for about 8 months after BMT, he died of disease recurrence 14 months after the diagnosis was made. ENKL of the small intestine follows a highly aggressive course. We describe the usefulness of DBE for diagnosis and management for ENKL of the small intestine. Additional cases, however, should be accumulated to establish optimal treatment strategy.

Abstract
AIMS To investigate the clinicopathological features, treatment outcomes, and prognostic factors in patients with extranodal natural killer (NK)/T-cell lymphoma, nasal type. MATERIALS AND METHODS We retrospectively reviewed the medical records of 115 patients diagnosed with extranodal NK/T-cell lymphoma, nasal type who were admitted to our hospital between January 1991 and June 2006. RESULTS In total, 107 patients were available for follow-up. After the completion of treatment, 48 patients (44.9%) achieved a complete remission. By the end of the follow-up period, 60 patients (56.1%) had died from local recurrence or metastases. The mean survival duration was 70.0 months, the median survival duration was 42 months, and the 5-year survival rate was 39.4%. The mean survival durations of the three treatment groups of chemoradiotherapy, radiotherapy and palliative treatment were 91.6, 60.1 and 17.6 months, respectively. The median survival durations were 72.0, 42.0 and 10 months, respectively. Patients treated with > 50 Gy had better local control and survival than the < 50 Gy group. However, there was no significant difference between patients having fewer than four cycles of chemotherapy and patients having more than four cycles. Multifactor Cox regression model analysis showed that B symptoms, gender, International Prognostic Index (IPI) score, disease stage and therapy were all independent prognostic factors. CONCLUSIONS The prognosis of extranodal NK/T-cell lymphoma, nasal type is poor and significantly influenced by B symptoms, gender, IPI score, clinical staging and the method of treatment. Chemoradiotherapy should be the first choice for treatment.

Abstract
Gastric involvement of extranodal natural killer/T-cell lymphoma, nasal type is extremely rare, and its clinicopathologic features are also poorly understood. Until now, only 4 cases have been reported in literature. In this article, 3 cases of extranodal natural killer/T-cell lymphoma, nasal type are reported. In this current series, one patient (case 2) was admitted to emergency due to life-threatened hemorrhage of the upper-digestive tract and the volume of blood loss was about 2000 mL. For case 3, the sample was a small piece of gastroendoscopy biopsy tissue. It is a challenge for pathologist to make the diagnosis for this special type of tumor. In all, 2 of 3 cases had a relevant history of midfacial extranodal natural killer/T-cell lymphoma, nasal type before. The other patient died of tumor 2 months later with no history of the tumor when she was alive. Literature review was carried out; The cases reported in this article are documented and compared with the 4 previously reported cases of tumor.

Abstract
To define the specific genetic alterations in nasal natural killer/T-cell lymphoma (N-NK/T-L), the assay of restriction landmark genomic scanning (RLGS), a genome-wide method, was used to investigate a pair of genomic DNA from N-NK/T-L cells and peripheral blood leukocytes of the same patient. The intensified spots in displayed N-NK/T-L gel of RLGS were subjected to bioinformatic analysis by virtual genome scan (VGS) and one of candidate spots proved to be T-bet gene (T-box expressed in T-cell). The pair of samples was consequently analysed by Southern hybridization, revealing genomic amplification of T-bet but not different status of DNA methylation. The amplification of T-bet was also discovered in other cases of N-NK/T-L by dot blotting. The expression of T-bet was investigated by in situ hybridization (ISH) and immunohistochemistry (IHC). The results showed that T-bet predominantly expressed in N-NK/T-L (ISH: 90.0%, 18/20; IHC: 80%, 16/20), while few cases of B-cell lymphoma (ISH: 11.8%, 2/17; IHC: 17.6%, 3/17) or T-cell lymphoma (ISH: 33.3%, 2/6; IHC: 16.7%, 1/6) were positive. The difference of T-bet expression in either ISH or IHC between N-NK/T-L and B-cell lymphoma or T-cell lymphoma was statistically significant (P < 0.05). Moreover, the expression of T-bet was not detected in normal spleen tissue and chronic inflammatory nasal mucosa. The results suggested that the amplification of T-bet gene or resulting its over-expression of T-bet gene might be involved in the development of N-NK/T-L and thus it should be worth confirming whether the over-expression of T-bet be helpful to the diagnosis of N-NK/T-L in further study.

Abstract
Nasal natural killer/T-cell lymphoma (N-NK/T-L) is prevalent in China. To further characterize this neoplasm, 36 cases of N-NK/T-L from 304 cases of malignant lymphomas in the north China area were investigated by histopathology, immunophenotyping, and genomic analysis of c-kit, in comparison with 11 cases of B-cell lymphoma (BCL) at the same region and 5 cases of nodal peripheral T-cell lymphoma (PTCL) (unspecified). Histopathologically, N-NK/T-L was characterized by coagulative necrosis, inflammatory background, and angiodestructive growth pattern. In 36 cases of N-NK/T-L, 27 cases (75.0%) were stained for CD45RO and 25 (72.2%) for CD3epsilon. Thirty cases (83.3%) were positive for T-cell intracellular antigen-1, 22 (61.1%) for granzyme B, 18 (50.0%) for CD56, and 11 (30.6%) for CD30, whereas none was positive for CD117. All 5 cases of PTCL displayed positive staining for CD45RO and T-cell intracellular antigen-1, 3 cases for CD3epsilon, but only 1 case for granzyme B. All 11 BCLs presented positive staining for CD20 and CD79a but negative for other antibodies. A significant relationship was observed between neoplastic cells pleomorphism and granzyme B expression (P < .05). Despite the fact that all cases were negative for CD117 staining, genomic sequences of c-kit 11 and exon 17 sequencing showed that 8 (26%) of 31 cases N-NK/T-L proved to contain genomic mutations, including 4 cases in exon 11 and 4 in exon 17. For the control group, only 1 (9%) of 11 BCLs and 1 (20%) of 5 cases of PTCL were detected to harbor mutations in exon 11. All mutations detected in 3 groups were missense by base substitution, and codes 571, 572, and 821 were hot spots. The results suggested that, in addition to histological features and routine immunophenotyping, granzyme B expression should be a more reliable marker in correct diagnosis of N-NK/T-L, and genetic analysis of c-kit mutation should be helpful in the diagnosis of this tumor.
