Abstract
Mitomycin C (MC) is used as therapy against solid tumors, also combined with other chemotherapeutic agents or radiotherapy. It may cause acute, subacute, or chronic anemia capable of modifying the results of chemo- and radiotherapy. Erythropoietin may be lowered by cancer itself or because of chemoradiotherapy. There are few studies investigating the relationship between erythropoietin and chronic anemia.We prospectively analyzed the chronic anemia and erythropoietin in 38 patients with solid cancer. Patients were 40 to 82 years of age. MC was randomly given every 3 weeks as a single drug at 10 or 20 mg/m². When myelotoxicity occurred the next therapy cycle was delayed until recovery. RBC indices, hemolysis, erythropoietin, liver and kidney function were studied. MC cycles were 136 (3.6 ± 1.4 per pt), 32 being delayed because of myelotoxicity.Hematocrit, hemoglobin and RBC were inversely related to the cumulative dose (r = 0.70 to 0.86; p 0.03 to 0.01) of MC. Other tests remained stable. Anemia occurred almost twofold earlier in the 20 mg/m² group (p=0.049). basal erythropoietin, already lower than in age and sex watched 81 non cancerous subjects (p<0.001), decreased during MC therapy (p<0.01). For each given MC mg/m² a 0.0372 Hb mg/dl reduction occurred. Chronic anemia due to MC is accompanied by erythropoietin reduction. These results can help in designing chemoradiotherapy.

Abstract
BACKGROUND Chemotherapy of non-small-cell lung cancer (NSCLC) has been improved by the use of cis-platin (P) and the pyrimidine antimetabolite gemcitabine (G) (2',2'-difluorodeoxycytidine). GP regimens currently used in Italy for NSCLC were and are mainly based on G day 1, 8 and 15; P on day 2, every 28 days (4 Day-Hospital admissions per cycle). However, the third G dose is frequently omitted because of myelo-toxicity, with a consistent dose decrease of both G and P in comparison with the intended dose. The 24-h lag time from 1(st) G and P has not reasonable clinical pharmacology base. AIM OF THE STUDY To have a simplified GP regimen based on two Day-Hospital admissions per cycle, with G on day 1 and 8, P after G on day 8; every 21 days, with the goal to use it in the neoadjuvant setting. MATERIAL AND METHODS The study was designed as a controlled, prospective, multicentre investigation, based on G (1500 mg/m(2)) on day 1 and 8, and P (100 mg/m(2)) on day 8 immediately following G, administered on a 3-week cycle. Quality of life (EORTC) was valuated in 46 patients out of 95 valuable patients. Restaging procedures were repeated after the 3rd and the 6th cycle. RESULTS Enrolled patients were 105 (stage IV: 63: IIIB: 29; IIIA: 13). GP cycles were 488 (1 to 6 per patient) 95 patients had at least 3 cycles and 59 of them had further 3 cycles. Myelotoxicity >or= g3 was mainly neutropenia, easily amenable with symptomatic and GCSF therapies (12.6% neutropenic fever); PNS toxicity occurred in 17.9% of patients. QoL was ameliorated (P < 0.05). Therapy was tolerable and gave a Response Rate (RR) of 52.3% after 3 cycles (Intention-to-treat analysis) and of 57.9% in 95 valuable patients who received at least 3 therapy cycles. CONCLUSION Present results confirm a good efficacy and/or synergism of G to P, with G on day 1 and 8 and P on day 8. This two day-hospital admissions regimen is at least as good as more complex GP regimens, and may be proposed in the neoadjuvant setting.

Abstract
17155 Background: Platin (P) salts and Gemcitabine (G) are used for NSCLC. GP regimens frequently included G on day 1, 8 and 15; P on day 2; every 28 days. However, the third G dose often is omitted because of myelo-toxicity, with a consistent no respect of the intended drugs’ doses. We devised a simplified regimen, based on two Day-Hospital admissions per cycle (c), with G on day 1 and 8; P after G on day 8; every 21 days. Aim of study: a high RR within the first 3 c.s for a GP regimen for neoadjuvant therapy. Methods: This prospective, multi-centre investigation included G (1500 mg/m2) on day 1 and 8, and P (100 mg/m2) on day 8 immediately following G, on a 3-weeks-c. Eligible criteria: age 18 to 75 years, NSCLC histologically, no previous chemotherapy, KPS 50%, WBC ≥ 4.0 × 109/L, platelet ≥100 × 109/L and normal kidney-liver function. QoL evaluation: 46 out of 95 valuable patients. Restaging procedures: repeated 3 and 6 c.s. Results: Out of 105 patients, 95 had at least 3 c.s and 59 of them had further 3 c.s. Myelo-toxicity ≥ G3 was mainly neuthropoenia, easily amenable with symptomatic and GCSF therapies; PNS toxicity occurred in 17.9% of patients. QoL was ameliorated (p < 0.05). Therapy was tolerable; gave RR was 52.3% after 3 c.s (Intention-to-treat analysis) and 57.9% in 95 valuable patients after at least 3 therapy c.s. In the 95 valuable patients over the first 42 days, i.e. after 2 c.s and just before the third c., 10 c.s out of 190 were delayed by one week, with a dose intensity reduction of 5.29%. Conclusions: This two Day-Hospital admissions regimen is at least as good as more complex GP regimens, with an appreciable RR after 3c.s; it may be proponed in the neoadjuvant setting.

Abstract
BACKGROUND The pyrimidine antimetabolite Gemcitabine (G) (2',2'-difluorodeoxycytidine) is used against several malignancies G exerts its antitumour effect mainly by incorporation of its triphosphate metabolite (dFdCTP) into DNA. Subsequently, DNA polymerase adds one additional deoxynucleotide and DNA synthesis is interrupted. The nuclear enzymes topoisomerase I and II (TPs) are critical for DNA function and cell survival; they control, maintain and modify DNA topology during both replication and translation of genetic materials. These enzymes induce cuts in one or both strands of DNA, allowing strands to pass through the nick and then rejoining the nicked strand of DNA. Anti-topoisomerase (TPs-inhibitors) drugs exist and are largely used in chemotherapy, however, most often blindly of the cancer TPs status. AIM To understand the best association between G and TPs-inhibitors, we studied: (a) Topoisomerases I, II alpha and II beta mRNA expression in Peripheral Mononuclear Blood Cells (PBMCs) of patients with solid tumor, after 1, 2, 3, 4, 5, 6 h after treatment with Gemcitabine (G); b) in vivo expression of TPs genes after administration of Gemcitabine (a topoisomerases up-regulating drug) combined with the TPs inhibitors drugs (TID) Topotecan (T) and Etoposide (E), added to the culture beneath 1 h after TPD treatment. TPs mRNA expression was measured by quantitative real-time RT-PCR in PBMCs. RESULTS The administration of 1-h infused G is followed by a fast rise of TPs expression (P > 0.0001 Student's t test, paired data, each patient control of himself); TPs inhibitors, sequentially given after G, highly reduced the TPs rising (P > 0.0001). CONCLUSIONS G induces a TPs increase. A rationale might be available for combination chemotherapy (G plus TPs inhibitors). The study is ongoing to enroll further patients.
