The therapeutic targeting of tumours or components of the immune system with molecule-specific monoclonal antibodies mAb is now considered a viable treatment option for cancer patients. One of the currently applied antibodies in clinics is represented by rituximab Rituxan that targets B cells for elimination by binding the B cell-associated marker CD It has been shown that an intact B cell compartment is critical for the therapeutic activity of MD against established tumours. B cells were confirmed to trigger tumour cell apoptosis by FcR-mediated cross-linking of the MD mAb in vitro and in vivo B lymphocytes were critical for directly triggering MDmediated tumour cell apoptosis.
Although the role of B-cells in human CRCs is still not completely characterized, B-cell-deficient mice exhibit spontaneous regression of MC38 colon carcinoma cells.

Studies involving BCR transgenic mice indicated that B lymphocytes might inhibit antitumor T lymphocytes responses by antigen-nonspecific mechanisms. Shah et al investigated the role of B lymphocytes in tumour immunity by studying immune responses of mice genetically lacking B lymphocytes to primary tumours.
In contrast to infiltration of cells responsible for chronic inflammation, the presence of high numbers of T lymphocytes has been reported to be a positive prognostic factor in several cancers. The first reports on the beneficial effect of lymphocytic infiltration in CRC appeared already in the Eighties. Thus, besides a Th-1 response signature, the other key feature of an effective immune response is the ability of T cells to reach the site of the tumour and to infiltrate it.
Because T-cell infiltration is not spatially homogeneous in CRC, attention has been focused on the predictive values of T lymphocytes located in the center of the tumor CT , along the invasive margin IM and in lymphoid aggregate mainly detectable in proximity of the tumor these aggregates are called tertiary lymphoid structures [ 80 , 81 ].
Immune Responses to Cancer
They found an association between evidence of an immune reaction within the tumour and the absence of tumour local invasion of vascular, lymphatic, and neural structures collectively referred to as VELIPI. The immunohistochemical analysis of adaptive immune markers i. Further, the combined analysis of both tumour regions improved the accuracy of survival prediction compared with single-region analysis[ 18 ]. Independently, Deschoolmeester et al[ 83 ] showed that the presence of a pronounced lymphocytic infiltration within the tumour is associated with improved survival.
The improved survival associated with infiltration of T lymphocytes has been suggested to result from the effective suppression of micrometastases. In addition, tumour cells secrete substances in the stromal compartment, which might be recognized by the immune system that subsequently attack the tumour.
A weak adaptive immune reaction correlated with a very poor prognosis even in patients with early tumour invasion. Conversely, a high density of adaptive immune cells correlated with a highly favourable prognosis whatever the local extent of the tumour and the regional lymph node invasion.
In mice, targeted disruptions of genes that encode critical components of the immune system i. These findings make it possible to hypothesize an immune-mediated control of tumour development by the adaptive compartment. The associations of a prognostic biomarker with a given disease, strongly suggests its stage-dependency as outcome predictor. Most MSI CRCs show a pronounced intra-tumoral inflammatory reaction in fact a criterion for MSI testing , the mechanistic explanation of which, however, is still incompletely understood.
The presence of these cytotoxic T lymphocytes has been attributed to the inherently greater production of abnormal peptides as a result of unreliable DNA repair in MSI-positive tumours. It is known that truncated peptides produced by frameshift mutations due to MSI may be immunogenic and contribute to the host immune response.
However, little is still known about the interrelationship between tumour-infiltrating T lymphocytes, MSI status, and other tumour molecular features.

It is indubitable that to define the prognostic effect of tumour-infiltrating T-cells independently of those potential confounders, large studies of CRC with extensive molecular characterization are needed. Additionally, caution is needed before incorporating tumour-infiltrating T cells into tumour staging.
To minimise the risk of inappropriate tumour down-staging at diagnosis, survival data need to be confirmed in independent series of patients studied in the past decade. Moreover, the association has to be conclusively proven between low densities of tumour-infiltrating T cells and the clinical detection of metachronous metastases, which remains the most appropriate outcome measure for recognising a role of the local immune response in micrometastasis suppression.
CD3-immunostaining of CRC tissue might therefore be useful for selecting stage II patients who, because they are at very low risk for cancer progression, could be spared adjuvant treatments. Nosho et al[ 86 ] examined the prognostic role of tumour-infiltrating T-cell subsets in a database of CRCs from two prospective cohort studies.
It is accepted that human cancer is a complex dynamical disease[ 87 , 88 ]. It is also now well recognized that cancers are not just composed of malignant cells, but that they are microenvironment consisting of many cell types, including a range of immune cells.

- INTRODUCTION.
It is indubitable that the antitumor immune response involves the interaction of several cell types and products Figure 2 , of the adaptive as well as of the innate immune system. It is also clear that CRC can escape immune surveillance using several strategies. The molecular profiles of the function and interaction of innate and adaptive immune cells, and the definition of tumor antigens have all led to build the basis of the knowledge of how the immune system modulates tumor growth and inhibition. It is indubitable that the analysis of the type, quantity, location and the functions of the immune infiltrate becomes a primary step in understanding CRC natural history, and, in a clinical perspective, its prognostic determinants.
A comprehensive analysis of all components of the lymphocytic infiltrates in the context of their localization, organization and impact at various steps of tumor progression remains largely, if not entirely, to be reported to prospective studies. In parallel, understanding the mechanisms of efficient immune reactions, the place where they are initiated, the cells and key cytokines and chemokines involved Figure 2 , and their impact at different stages of the disease should provide new tools and goals for more effective and less toxic targeted therapies.
