Non-Hodgins’s lymphoma (NHL) is the most common hematological malignancy worldwide, accounting for nearly 3% of cancer diagnoses and deaths. NHL is the seventh most prevalent cancer and has the sixth highest mortality among cancers in the US. NHL accounts for 4% of US cancer diagnoses, and incidence has increased 168% since 1975 (while survival has improved 158%). NHL is more common among men, those >65 years old, and those with autoimmune disease or a family history of hematological malignancies. NHL is a heterogenous disease, with each subtype associated with different risk factors. Marginal zone lymphoma (MZL) is strongly associated with Sjogren’s syndrome (SS) and Hashimoto’s thyroiditis, while peripheral T-cell lymphoma (PTCL) is most associated with celiac disease. Occupational exposures among farm workers or painters increases the risk of most of the common subtypes. Prior radiation treatment, obesity, and smoking are most highly associated with diffuse large B-cell lymphoma (DLBCL), while breast implants have been rarely associated with anaplastic large cell lymphoma (ALCL). Infection with Epstein–Barr Virus (EBV) is strongly associated with endemic Burkitts lymphoma. HIV and human herpes virus 8 (HHV-8), is predisposed to several subtypes of DLBCL, and human T-cell lymphoma virus (HTLV-1) is a causative agent of T-cell lymphomas. Obesity and vitamin D deficiency worsen NHL survival. Atopic diseases and alcohol consumption seem to be protective against NHL.

Alimentary lymphomas arising from T cells are rare and aggressive malignancies in humans. In comparison, they represent the most common anatomical form of lymphoma in cats. Due to the low prevalence in humans, the underlying pathomechanism for these diseases is poorly characterised, limiting experimental analysis and therapeutic exploration. To date, activating mutations of the JAK/STAT core cancer pathway and particularly the STAT5B oncoprotein have been identified in human enteropathy-associated T cell lymphoma. Here, we describe a high homology of human and feline STAT3 and STAT5B proteins and strong conservation at the genomic level. Analysis of 42 samples of feline T cell alimentary lymphoma reveals broad activation of STAT3 and STAT5B. Screening for known activating mutations in STAT3 or STAT5B identifies the presence of the STAT5BN642H driver mutation in feline enteropathy-associated T cell lymphoma in 7 out of 42 (16.67%) samples in total. Regarding lymphoma subtypes, the majority of mutations with 5 out of 17 (29.41%) cases were found in feline enteropathy-associated lymphoma type II (EATL II). This identification of an oncogenic STAT5B driver mutation in felines recapitulates the genetic situation in the corresponding human disease, thereby establishing the cat as a potential new model for a rare and incurable human T cell disease.

Although most patients with the cutaneous T-cell lymphoma, mycosis fungoides (MF), are seronegative for human T-cell lymphotropic virus-I or -II (HTLV-I/II) when tested by assays that measure only antibodies to the viral structural proteins, the majority of such patients harbor HTLV-I-related pol and tax proviral sequences that encode proteins not included in routinely used serologic tests. Tax mRNA has also been detected in their peripheral blood mononuclear cells (PBMC). Therefore, it seemed possible that these patients have antibodies to the tax protein. To investigate this, enzyme-linked immunosorbent assays (ELI-SAs) and Western blot assays were set up, using as antigens the full-length HTLV-I tax cloned from the prototypic HTLV-I-infected cell line, C91PL, and from PBMC of a MF patient, as well as a synthetic peptide made to the carboxy-terminal 20 amino acids of tax-I. Of 60 MF patients whose PBMC were shown to be positive for tax proviral DNA and mRNA, 50 (83%) were shown to have tax antibodies. The antigen derived from the MF patient was most useful in detecting such antibodies. These results demonstrate the need for including other HTLV-related antigens in addition to gag and env in serologic tests used to identify HTLV-infected individuals. The findings underscore the fact that individuals considered seronegative on the basis of currently used tests can be infected with HTLV.

Abstract We have studied the clinical effects of a murine monoclonal anti-human T-cell antibody in seven patients with T-cell lymphoma. Four to 17 treatments with anti-Leu-1 were given to each patient over periods of 14–75 days. Doses of antibody ranged from 250 micrograms to 100 mg. Antibody treatments usually caused a rapid fall in circulating T cells, with return to baseline levels within 24–48 hr. The optimum dose appeared to vary for each patient. Clearance of circulating tumor cells correlated with the amount of antibody bound to cells. Other than dyspnea in one patient, no serious toxicity was noted. Five patients had definite tumor responses, but these were of short duration (1.5–4 mo). Four patients developed anti-mouse immunoglobulin (Ig) antibodies, and in three patients, this was responsible for tumor escape from therapy. Although 95% of the host anti-mouse Ig response was directed against mouse Ig constant region determinants, a small but significant component was found to be antiidiotype.
