Abstract
Until recently cancer medical therapy was limited to chemotherapy that could not differentiate cancer cells from normal cells. More recently with the remarkable mushroom of immunology, newer tools became available, resulting in the novel possibility to attack cancer with the specificity of the immune system. Herein we will review some of the recent achievement of immunotherapy in such aggressive cancers as melanoma, prostatic cancer, colorectal carcinoma, and hematologic malignancies. Immunotherapy of tumors has developed several techniques: immune cell transfer, vaccines, immunobiological molecules such as monoclonal antibodies that improve the immune responses to tumors. This can be achieved by blocking pathways limiting the immune response, such as CTLA-4 or Tregs. Immunotherapy may also use cytokines especially proinflammatory cytokines to enhance the activity of cytotoxic T cells (CTLs) derived from tumor infiltrating lymphocytes (TILs). The role of newly discovered cytokines remains to be investigated. Alternatively, an other mechanism consists in enhancing the expression of TAAs on tumor cells. Finally, monoclonal antibodies may be used to target oncogenes.

Abstract
A patient with chronic T-cell leukemia characterized by a suppressor phenotype is reported. A 71-year-old woman presented with symptoms and signs of hypercalcemia. Peripheral blood specimen showed abnormal lymphoid cells with an oval to cleaved nucleus, rather condensed chromatin, occasional prominent nucleolus, and basophilic cytoplasms with vacuoles which seems to be a T-cell counterpart of B-cell chronic lymphocytic leukemia with mixed cell types. The phenotype of these cells was CD4-, CD8+, CD5+, CD6+ with poor expression of CD3, CD7, and CD25. Southern blot analysis of T-cell receptor beta-chain gene revealed one allele rearranged band. The serum antibodies were positive against human T-cell leukemia virus, type I-associated antigens, but monoclonal integration of proviral DNA was not detected in the leukemic cells suggesting that she was just a carrier of this virus. Interestingly, serum PTH-related peptide (PRP) was elevated. The combination therapy with vincristine and prednisolone for leukemia decreased not only the number of leukemic cells but also the serum PRP levels. The clinical course was aggressive. She only responded transiently to treatments, and died of renal failure due to uncontrollable hypercalcemia six weeks after admission.

Abstract
The clinical, morphological, immunological, and molecular features of a case of expansion of large granular lymphocytes (LGL) are reported. Surface marker analysis of peripheral blood and spleen mononuclear cells showed that the majority of these cells were CD3-, CD2+, CD16+, and Leu 7-. Ultrastructural characteristics of CD16+ cells revealed a low nuclear/cytoplasmatic ratio, irregularly shaped nucleus, and numerous cytoplasmatic granules. Functional studies showed reduced proliferative responses to mitogens (PHA, Con A, PWM) and high levels of natural killer (NK) activity as well as antibody-dependent cell cytotoxicity (ADCC) and lymphokine-activated killer (LAK) activities. Molecular analysis of the T cell receptor genes revealed a germline configuration of the beta, gamma, and delta genes; however, as for normal NK cells, delta-related mRNA transcripts were found. Three months from diagnosis, the patient developed profound thrombocytopenia and splenectomy was carried out with complete normalization of the platelet counts and of hematological values while LGL lymphocytosis persisted. Although no tools are available for studying the monoclonality of CD3- lymphoproliferative disease, the clinical course, the absence of chromosomal abnormalities, and a liver histology indicative of chronic active hepatitis suggest that LGL expansion in this patient could be part of a benign, possibly reactive, process.

Abstract
Adult T-cell leukemia (ATL) and T-cell chronic lymphocytic leukemia (T-CLL) are hematologic neoplasms in differentiated stages of peripheral mature T cells. This is suggested by the presence of CD2 (E rosette receptor) and mature and/or pan-T cell membrane surface antigens on their leukemic cells. We recently encountered one patient with ATL and another with T-CLL; their leukemic cells poorly expressed CD2 antigens, but clinical presentation, morphology of the leukemic cells and other marker studies were characteristic of either ATL or CLL. The clinical significance of the poor expression of CD2 remains to be further studied. The two patients reported here died of severe complications 4 and 9 weeks after diagnosis. The poor expression of CD2 in the peripheral T cells in these neoplasms is likely to indicate an aggressive nature of the disease.

Abstract
A multiparameter analysis, which included the evaluation of clinical features, cell morphology, karyotype, phenotypic and functional immunologic findings, and T-cell receptor beta-chain configuration was performed on 34 patients with lymphoproliferative disease of granular lymphocytes (LDGL). The two-fold aim of the study was to identify the most useful tools that would more accurately characterize these patients and to deal with the problem of classifying these lymphoproliferative disorders. The data presented in this article suggest that a single parameter may not be sufficient to define the nature of the proliferating cells or to predict the clinical course of the disease and prognosis for the patient. The use of a multiparameter approach, however, may reach this goal, thus providing important prognostic and therapeutic information. Our study supports the concept that lymphoproliferative disease of granular lymphocytes is a heterogeneous disorder that ranges from indolent and possibly reactive conditions to the manifestation of aggressive malignancies.

Abstract
In this study we describe 2 patients who appear to suffer from a morphological, cytochemical and clinico-haematological variant of T-prolymphocytic leukaemia (T-PLL). The cells were smaller than typical prolymphocytes, with a regular nucleus containing a smaller and less prominent nucleolus; the alpha-naphthyl acetate esterase (ANAE) and acid phosphatase (AP) cytochemical reactions showed a weaker pattern of positivity in this variant compared to T-PLL. No immunological differences were found between the two conditions with regard to membrane expression and functional behavior of the cells. The clinical course and the outcome of the patients appears to be different: aggressive and rapidly fatal in T-PLL; thus far well-controlled in the T-PLL variant. From a molecular point of view, both cases showed a monoclonal rearrangement of the T-cell receptor beta-chain gene.

Abstract
The clinical, morphological, immunological and molecular features of seven patients with a stable picture of chronic granular lymphocytosis, observed over a period of up to 4 years, were studied. Mild splenomegaly was detected in one patient, while lymphoadenopathy and hepatomegaly were absent. Surface marker analysis showed in five patients the common membrane phenotype of granular T-cell lymphocytosis (T3+, T4-, T8+, Leu-7+); of the remaining two, one presented an unusual phenotype (T3+, T4+, T8+) and the other showed a marked positivity with the Leu-11 and M1 monoclonal antibodies, but lacked the T3, T4, T8 antigens. Three cases had a low (less than 30%) expression of the T1 antigen. Functional studies showed that the proliferative response to PHA and the NK function were reduced in four of the seven cases. Molecular analysis, performed in six cases, revealed a monoclonal rearrangement of the T-cell receptor beta-chain gene in three, a polyclonal T-cell configuration in two and a germ-line arrangement in the last. All three monoclonal cases showed a depressed NK activity and two a reduced PHA response. The results of this study document the heterogeneity of granular lymphocyte expansions and suggest that the clonal or reactive nature of these often indolent proliferations, suspected on the basis of immunologic functional studies, may be recognized at the DNA level.

Abstract
A patient with Chronic Lymphocytic Leukemia (CLL) characterized by an expansion of helper phenotype mature T lymphocytes is here described. The phenotype of these cells was OKT3+, OKT4+, Leu 9+, 5/9+, OKT8-, Tac- and functional studies showed a strong helper activity on B cell differentiation; an "in vivo" presence of an IgG-lambda paraproteinaemia has been demonstrated. Cytogenetic studies showed multiple clonal, numerical and structural rearrangements which included a tandem t(14;14) (q11;32) translocation. Hybridization showed HTLV I related specific bands indicating the presence of exogenous sequences related to prototype virus but derived from a different Retrovirus (HTLV 1c). The clinical course was aggressive and unsuccessful treatments with various polichemotherapeutic protocols, associated with multiple leukaphereses, were performed. The authors underline that despite the morphological, immunological, biological and virological heterogeneity, the common feature of T-helper CLL is the inexorable clinical course which needs a new therapeutic approach.

Abstract
6 patients with a chronic, clinically heterogeneous proliferative disorder of the large granular lymphocytes (LGL) were investigated. In each case the majority of peripheral blood lymphocytes reacted with HNK-1, OKT3 and T11 monoclonal antibodies, whereas morphology and other immunological features varied from case to case. 2 cases were of particular interest. 1 patient had an expansion of HNK-1 stained, large agranular rather than granular lymphocytes; another patient's LGL simultaneously expressed HNK-1, OKT4 and T8 antigens. The heterogeneous features of these abnormally expanded cell populations are similar to those of the normal cell subsets from which they are likely to have originated.

Abstract
T-cell chronic lymphocytic leukemia (T-CLL) accounts for about 2% of the various types of CLL and can be subtyped into helper/inducer (h/i) and cytotoxic/suppressor (c/s) cell membrane phenotypes. Seven patients with CLL were shown to have T-CLL with a h/i cell membrane phenotype; four with monoclonal antibody reagents and three by demonstration of the E-rosette receptor and focal acid alpha naphthyl acetate esterase activity. The clinical courses, treatment responses, and laboratory findings of these seven patients were reviewed to determine the prognosis and unique clinicopathologic features of this subtype. Two patients presented with skin rashes, and five were diagnosed during evaluation for other medical problems. Initially, four patients had splenomegaly and two had lymphadenopathy, but none of the patients had hepatomegaly. Morphologic examination revealed uniform, small lymphocytes in three patients, and the lymphocytes had nuclear indentations in four patients. Sera from the three patients tested were negative for antibody to the human T-cell leukemia/lymphoma virus I. Peripheral blood mononuclear cells from one patient showed normal interleukin-2 production and lacked antibody-dependent cell-mediated cellular cytotoxicity and natural killer activity. Cytogenetic analysis was done on one patient, revealing an abnormal clone with several chromosomal abnormalities, including an X;14 translocation with a break point at 14q11. All patients required chemotherapy, and all died a median of 21 months from the time of diagnosis. The findings in these patients, in addition to those in 31 patients described in the literature, indicate that h/i T-CLL is associated with a poor prognosis and has distinct clinical and pathologic features that separate it from c/s T-CLL, adult T-cell leukemia/lymphoma, the cutaneous T-cell lymphomas, and B-CLL.

Abstract
An epidemiological survey on the presence of serum antibodies to human T lymphotropic retrovirus III (HTLV-III) is reported. The study was carried out on people living in large as well as small cities in different Italian regions. Serum samples of 21 patients with AIDS, 402 with ARCS, and 920 from individuals at risk for these diseases were analyzed. The percentage of positive sera varied from 81% in AIDS, to 100% -33.3% in ARC according to the different geographical areas and/or the various categories of people with ARC. The percentage of positive sera in individuals at risk for AIDS or ARC varied from 11.9% in homosexuals, to 21% in drug abusers and 23.1% in haemophiliacs. No positive sera were observed among 660 normal individuals, relatives of patients with AIDS or ARC and in 114 patients suffering from immunological or infectious disease and among people at risk living in small cities. Sera were also negative in patients with classical Kaposi's sarcoma or T-cell chronic lymphocytic leukemia. Since none of the 660 unselected normal adults were positive while a significant percentage of people at risk for AIDS showed antibodies to HTLV-III, we may presume that this infection is prevalent in the Italian categories in which AIDS and ARC are most likely to develop.

Abstract
Sixteen Italian patients with chronic T-cell lymphocytic leukaemia (T-CLL) and leukaemic T-helper phenotype lymphocytes (Thp-CLL) were investigated for serum antibodies against human T-cell leukaemia virus I (HTLV-I) or its integrated DNA sequences. Common features of this series of patients were an aggressive clinical course with poor response to treatment, high white blood-cell count, bone-marrow infiltration, splenomegaly, and chromosome abnormalities. Three patients had skin infiltration and one had hypercalcaemia. Immunological analysis showed a Thp (OKT4+) in all cases, and a heterogeneity, within the OKT4 population, of phenotypes and functional activities. Three patients had either HTLV-I integrated DNA sequences or anti-HTLV-I serum antibodies, or both. These patients had not received any blood transfusions, denied intimate contact with foreigners, and had always lived in small towns of central or southern Italy. Clinical and immunological findings in this series of patients suggest that both HTLV-I related and unrelated cases of Thp-CLL should be regarded as one disease arising from the same subpopulation of mature T-lymphocytes.
