“…33 (84.61%) of our cases had B cell lineage, 4 (10.25%) had T cell lineage and 2 (5.12%) of the cases belonged to miscellaneous group. The current study and similar reports from some of the surrounding Middle East countries as well as the West show a low relative proportion of T-cell lymphomas (Naresh et al, 2004;Economopoulos et al, 2005). It was claimed that non Hodgkin lymphoma, occurring in adolescence was an independent risk factor for a poorer prognosis compared with that occurring in children younger than 15 years of age (Cairo et al, 2003).…”

“…India shows an intermediate distribution pattern, between West Asian and East Asian countries: the frequency of T-or NK-cell lymphoma is usually higher than in the Western literature, but less than the frequency documented in some Asian countries. The frequency of ENKL (4.5 %) is similar to that reported in other Indian studies [10,17].…”

“…In Asia, proportion of AITCL among all T-and NK-cell lymphomas was 9.7 % in Japan, 9.4 % in China, 7.8 % in Korea, 7.2 % in Thailand, 6.9 % in India, and 4.1 % in Taiwan [4,[8][9][10][11][12]. AITCL is a primarily nodal disease with unique clinical findings.…”

Peripheral T-cell lymphomas (PTCLs) comprise a heterogeneous group of mature T-and NK-cell neoplasms, the incidence of which is higher in Asian countries than in Western countries. Although its etiology is mainly unknown, several risk factors (such as genetic factors, abnormal immunity, environmental factors, and infectious causes) have been proposed. PTCL are classified based on a combination of several parameters, including morphology, site of presentation, viral status, immunophenotype, and specific genetic alterations. Their classification is ongoing, with the emergence of new entities and refinement of existing entities because of the development of diagnostic markers and new genetic alterations. This review presents epidemiologic data for PTCL in Asia, together with recent progress in the pathology of PTCL compared with the WHO 2008 classification.Epidemiology T-and NK-cell lymphomas are uncommon: overall, they represent fewer than 25 % of all non-Hodgkin's lymphoma (NHL) [1][2][3]. The occurrence rates of various subtypes of T-and NK-cell lymphomas in Asia are significantly different from those observed in Western countries, and even among Asian countries. The incidence and distribution of T-and NK-cell lymphomas in several Asian countries is summarized in Fig. 1 and Table 1 [ [4][5][6][7][8][9][10][11][12][13][14][15].The frequencies of T-and NK-cell lymphomas seem to increase from West to East Asia. The occurrence rate of Tand NK-cell lymphomas are relatively low (\20 % of NHL) mainly in West Asia (Turkey 16.2 %, Iraq 19 %, and Kuwait 18 %) and South Asia (Pakistan 11.3 %, and India 20.2 %), but relatively high mainly in East Asia (China 32.5 %, Korea 22 %, and Japan 24.9 %) and Southeast Asia (Thailand 25 %). The proportion of T-and NK-cell lymphomas in Taiwan is very low (13.3 %) compared with that of other East Asian countries. Regarding the subtypes of T-and NK-cell lymphomas, two West (Turkey and Iraq) and one South (Pakistan) Asian countries share similar distribution patterns, presenting T lymphoblastic lymphoma (T-LBL) as the most common subtype, followed by peripheral T-cell lymphoma (PTCL) or anaplastic largecell lymphoma (ALCL). The frequency of mycosis fungoides/sezary syndrome (MF/SS) is very high in Kuwait. The distribution patterns of T-and NK-cell lymphomas in Thailand, Taiwan, and Korea are similar, whereas adult T-cell leukemia/lymphoma (ATLL) represents a high proportion of T-and NK-cell lymphomas in Japan. When ATLL is excluded, four countries (Thailand, Taiwan, Korea, and Japan) exhibit very similar patterns of subtype distribution of T-and NK-cell lymphomas. Extranodal NK/ T-cell lymphoma (ENKL) is frequent in China (48 %) and Korea (28.7 %), but is less frequent in Japan (10.4 %), as reported by a recent study performed by an international T-cell project [2]. In China, the frequency of T-or NK-cell lymphoma varies according to geographic region

BACKGROUND. Mantle cell lymphoma (MCL) is a distinct subtype of B‐cell non‐Hodgkin's lymphoma. To the authors' knowledge, little is known regarding its incidence patterns and associated factors. The purpose of the current study was to examine the incidence of MCL over a period of 13 years and to identify the factors associated with the incidence patterns. METHODS. Patients diagnosed with MCL between 1992 and 2004 were identified from the Surveillance, Epidemiology, and End Results (SEER) Tumor registries. SEER*Stat statistical software was used for analysis. RESULTS. Of the 87,166 patients diagnosed with non‐Hodgkin's lymphoma during the 13‐year period between 1992 and 2004, 2459 (2.8%) had confirmed MCL. The overall incidence of MCL (per 100,000) was 0.55, which increased with age: 0.07 in patients aged <50 years, 2.97 in patients aged 70 to 79 years, and 2.78 in those aged ≥80 years. The age‐adjusted incidence rate increased from 0.27 of 100,000 in 1992 to 0.69 of 100,000 in 2004, and the annual percent change was 5.87% (P < .05). The median age at diagnosis was 68 years. The incidence of MCL was higher in men (0.84 of 100,000) than in women (0.34 of 100,000) (P < .05), and was higher in Caucasians (0.61 of 100,000) than in African Americans (0.32 of 100,000). Late‐stage (III‐IV) MCL was diagnosed in 74.6% of patients. There were significant geographic variations noted (P < .05). CONCLUSIONS. The incidence of MCL increased from 1992 to 2004, and was significantly higher in men, in Caucasians, and patients aged ≥50 years. Most patients were diagnosed with late‐stage MCL, and there also were considerable geographic variations observed in incidence rate. Cancer 2008. © 2008 American Cancer Society.
