Cancer treatment can be adjuvant or palliative. Patients with haematological tumors are also included. Enrolment is also foreseen for patients with haematological tumors who are not undergoing active treatment yet, but are followed with a watchful waiting approach (e.g. patients with low-risk B-CLL or low-risk follicular lymphoma). Finally, enrolment is also open to patients with relapsing forms of non-melanoma skin cancers (e.g. basalioma, epithelioma).\n\nThe primary endpoint of the study is to evaluate the effects of a STMF on the circulating levels of factors with pro- or anti-oncogenic activity (including insulin, IGF1, IGFBP1, IGFBP3 , leptin, adiponectin, IL-6, TNF-alpha, IL1beta), as well as the effect of STMF cycles on leukocyte subpopulations with a role in the control of tumor growth, such as regulatory T cells, the "myeloid-derived suppressor cells" (MDSC) as well as NK cells, and on stem cell pools (e.g. hematopoietic stem cells, endothelial stem cells, mesenchymal stem cells).\n\nThe STMF regimen that is applied is a 5-day low-calorie and low-protein diet. Patients undergo a medical exam/history collection and a nutritional assessment (body weight, handgrip strenght and bioimpedance measurement) at baseline and then at the visits that precede every cycle of STMF (i.e. once every three weeks or monthly, depending on the therapeutic regimen the patient is undergoing, and in any case no more frequently than once every three weeks - eg when combined with q21 chemotherapy regimens). Adverse events are recorded at each visit in accordance with NCI-CTCAE version 5.0.
