RESUMO
OBJECTIVE: Cancer patients and family members can feel abandoned by their oncologist at the transition to end-of-life (eoL) care. In this study, we evaluated the level of satisfaction of family caregivers when the oncology team assisted the patient until death. METHODS: Two oncology units were reorganized to ensure continuity of care; oncologists trained in palliative care medicine assisted patients until death. Relatives who assisted the patient at home or at an inpatient hospice underwent a semi-structured phone interview >1 month after the patient's death. Satisfaction was measured using a five-point Likert scale ranging from very dissatisfied (score 0) to very satisfied (score 100). RESULTS: Relatives of 65 patients were contacted, 55 accepted the interview. Patients were followed at home (41) or at an inpatient hospice (14), for 1-24 weeks (median 3 weeks). A specific question on the relevance of the oncologist having a role in EoL care produced a score of 82. The overall satisfaction score was higher than in our previous study in which a continuity of care model was not adopted, with a score improvement from 55/100 to 84/100 (p < 0.001). SIGNIFICANCE OF RESULTS: A care program where the oncologist is involved in EoL management improved the satisfaction of caregivers of cancer patients. When a longstanding and trusting relationship has been established, the connection between the patient and the oncologist should not be lost.

BACKGROUND: Elderly patients are generally underrepresented in the study populations of combination chemotherapy trials. This study evaluates the efficacy and safety of a modified FOLFOX regimen in elderly patients with metastatic gastric cancer and presenting associated disease(s). METHODS: A total of 43 patients aged ≥70 years received oxaliplatin 85 mg/m(2) together with 6S-leucovorin 200 mg/m(2) on day 1, followed by a 46-h infusion of 5-fluorouracil 2,400 mg/m(2), every 2 weeks. Assessment of response was performed every four cycles according to RECIST criteria. RESULTS: Median patient age was 74 years (range, 70-83 years). Overall response rate was 34.9% [95% confidence interval (CI), 20.6-49.1, with 3 complete responses and 12 partial responses. Grade 3 neutropenia occurred in 4 patients (9.3%), fatigue in 3 patients (7.0%), and vomiting in 2 patients (4.6%). Grade 2 and 3 peripheral neuropathy was observed in 5 patients (11.6%) and 1 patient (2.3%), respectively. No treatment-related death was observed. Median progression-free and overall survival were 6.8 and 10.5 months, respectively. CONCLUSIONS: This modified FOLFOX regimen is an active and well-tolerated treatment for elderly patients with metastatic gastric cancer and also represents a good therapeutic option in patients with associated disease(s).

BACKGROUND: Clinical observations suggested that a non negligible proportion of patients, ranging from 40% to 70%, does not seem to benefit from the use of anti-EGFR targeted antibodies even in the absence of a mutation of the K- RAS gene. The EGFR pathway activation via the Ras-Raf-MAP-kinase and the protein-serine/threonine kinase AKT could determine resistance to anti-EGFR treatment. METHODS: We tested the interaction between phosphorylated AKT and MAPK expression in colorectal tumours and corresponding metastases and global outcome in K-RAS wild type patients receiving irinotecan-cetuximab. RESULTS: Seventy-two patients with histologically proven metastatic colorectal cancer, treated with Irinotecan and Cetuximab based chemotherapy, were eligible for our analysis.In metastases pAKT correlated with RR (9% vs. 58%, p = 0.004), PFS (2.3 months vs. 9.2 months p < 0.0001) and OS (6.1 months vs. 26.7 months p < 0.0001) and pMAPK correlated with RR (10% vs. 47%, p = 0.002), PFS (2.3 months vs. 8.6 months p < 0.0001) and OS (7.8 months vs. 26 months p = 0.0004). At multivariate analysis pAKT and pMAPK in metastases were able to independently predict PFS. pAKT in metastases independently correlated with RR as well DISCUSSION: pAKT and pMAPK expression in metastases may modulate the activity of EGFR-targeted antibodies. We could speculate that in patients with pAKT and pMAPK metastases expression targeting these factors may be crucial.

Preclinical data suggested that, in the presence of human epidermal growth factor receptor (HER)-3-altered activation, colorectal cancer cells may escape anti-epidermal growth factor receptor (EGFR)-mediated cell death. HER-3 overexpression may then represent a key factor for resistance to anti-EGFR antibodies in colorectal cancer. The aim of our analysis was to investigate a possible correlation between HER-3 expression and clinical outcome in wild-type K-RAS advanced colorectal cancer patients receiving cetuximab and irinotecan. We retrospectively analyzed immunoreactivity for HER-3 in wild-type K-RAS advanced colorectal cancer patients receiving irinotecan and cetuximab. Eighty-four advanced wild-type K-RAS colorectal cancer patients were available for HER-3 analysis. Forty patients (48%) had a HER-3(-) colorectal tumor, whereas the remaining 44 cases (52%) were deemed HER-3(+). In patients with HER-3(-) and HER-3(+) tumors, we observed a partial response in 17 (42%) and eight (18%) patients respectively; progressive disease occurred in 11 (35%) and 26 (53%) patients with HER-3(-) and HER-3(+) tumors, respectively (p = .003). The median progression-free survival time was 6.3 months in patients with HER-3(-) tumors and 2.8 months for those who had HER-3-overexpressing tumors (p < .0001). The median overall survival time was 13.6 months in patients showing HER-3(-) tumors and 10.5 months for those who had HER-3-expressing tumors (p = .01). HER-3 proved to be a predictive factor for clinical outcome in wild-type K-RAS colorectal cancer patients treated with cetuximab. Combined HER-3 and K-RAS analysis may represent an effective strategy for better selection of responding colorectal cancer patients.

Seventy to 40% of K-RAS wild type colorectal tumors does not seem to benefit from treatment with antiepidermal growth factor receptor (anti-EGFR) monoclonal antibodies. Recent data suggested that in presence of IGF-1 system, altered activation colorectal cancer cells may escape anti-EGFR mediated cell death. The interaction between IGF-1 expression and K-RAS mutational analysis was tested to verify the ability of IGF-1 to identify a subgroup of patients more likely to benefit from EGFR-targeted antibodies treatment. IGF-1 expression and K-RAS mutational status was assessed in advanced colorectal cancer patients receiving irinotecan/cetuximab. One hundred twelve patients were analyzed. IGF-1 was negative in 30 patients (27%) and overexpressed in the remaining 82 cases (73%). In IGF-1 negative and IGF-1 positive tumors, we observed progressive disease in 9 (30%) and 55 (67%) patients, respectively (p = 0.001). Median progression-free survival was 7.5 mo in patients showing IGF-1 negative tumors and 3 mo for IGF-1 expressing tumors (p = 0.002). Among K-RAS wild type patients, IGF-1 negative and positive tumors showed a partial response to cetuximab-irinotecan in 13 (65%) and 11 (22%) cases, respectively (p = 0.002). Median progression-free survival in IGF-1 negative tumors was 10 mo and 3.2 mo in IGF-1 positive colorectal cancers (p = 0.02). IGF-1 proved to be a possible predictive factor for resistance to anti-EGFR monoclonal antibodies in K-RAS wild type colorectal cancer. Combined IGF-1 and K-RAS analysis may represent an effective strategy for a better selection of responding colorectal cancer patients.

AIMS AND BACKGROUND: Triple-negative breast cancer, defined by a lack of expression of estrogen, progesterone and HER-2 receptors, accounts for 15% of all types of breast cancer. The subtype mainly includes a molecularly distinct subgroup, the basal-like subtype (accounting for 75% of all cases). We attempt to define triple-negative breast cancer and compare it with basal-like disease, review the molecular, pathologic and clinical features of triple-negative disease, provide an overview of a retrospective subset analysis of clinical trials, and outline ongoing therapeutic trials and possible paths for future research. METHODS: We collected data regarding classification, molecular and clinical features and treatment, drawn from the existing literature, including abstracts and verbal accounts. By the term "basal-like", we defined all cases where gene expression array or more sophisticated immunophenotypes are used for identification. When the analysis is restricted to clinical assay (immunohistochemistry), we refer to "triple-negative". RESULTS: Basal-like breast cancer expresses genes characteristic of basal epithelial cells, which include high-molecular weight basal cytokeratins (CK5/6, CK14, CK17), vimentin, p-cadherin, alpha B crystalline, caveolins 1 and 2 and EGFR. The expression of basal markers (basal cytokeratins and EGFR) is related to a worse prognosis and identifies a clinically distinct subgroup within the triple-negative breast cancer. BRCA1 mutations are present in 11% of triple-negative tumors and even more rare is BRCA2 deficiency. BR-CA1-associated breast cancers types are typically characterized by a high rate of DNA aberrations and defective DNA repair pathways (the so-called "BRCAness"). The use of regimens based on DNA-damaging agents, such as anthracyclines, platinum derivatives and cyclophosphamide seems a sensible option for this breast cancer subtypes. Clinical data support a strong sensitivity to primary chemotherapy with pathologic response rates ranging from 27-45% (with anthracyclines and taxanes) to more than 60% with platinum-based triplets. However, based on retrospective data, major response to chemotherapy does not carry better survival ("triple-negative paradox"). There is no specific targeted therapy in the armamentarium: ongoing trials include anti-angiogenic agents, anti-EGFR and EGFR-TK inhibitors, epothilones and PARP inhibitors. CONCLUSIONS: A specific systemic regimen cannot yet be recommended. Moreover, only a few data are available on which treatment selection can be based. Use of the existing cytotoxic agents can be optimized for this patient subgroup by investigating the proliferative signals and the suitability of these signals as therapeutic targets, besides assessing the BRCA1-pathway in this subgroup as regards treatment. A greater understanding of the pathologic and molecular characteristics of this phenotype may lead to customized treatment for these patients.

AIMS AND BACKGROUND: Italy is divided into 20 regions. As a consequence of local autonomy, following marketing authorization by the Italian Medicines Agency, each drug for hospital use is not immediately available, because its approval needs to undergo further steps that can be different among regions. The Italian Society of Medical Oncology conducted the present study to describe the impact of the existence of sub-national pharmaceutical formularies on the disparity of access to new anti-cancer drugs among patients treated in different Italian regions. METHODS: The availability of 8 new anti-cancer drugs at a regional level and the coherence of regional authorizations compared with national authorizations approved by the Italian Medicines Agency were analyzed as of April 2009. RESULTS: Fourteen regions and autonomous province of Trento have a regional pharmaceutical formulary. In most cases, the regional pharmaceutical formularies include the eight analyzed drugs, with therapeutic indications coherent with national marketing authorization indications. Five drugs (bevacizumab, trastuzumab, rituximab, erlotinib, sunitinib) were included in all the existing regional pharmaceutical formularies, without restrictions, whereas three drugs (cetuximab, sorafenib, pemetrexed) were found to have restrictions in some regions. CONCLUSIONS: The presence of multiple hierarchical levels of drug evaluation creates a potential element of disparity in the access to pharmacological therapies for Italian citizens.

AIM: This analysis evaluated the efficacy and safety of nivolumab, an immune checkpoint inhibitor, in elderly patients with stage IIIB or IV squamous non-small-cell lung cancer (NSCLC) enrolled in the expanded access programme (EAP) in Italy. METHODS: Nivolumab was available on physician request. Safety data included adverse events (AEs). Efficacy data included investigator-assessed tumour response, progression date and survival information. Results were analysed for patients aged <65, 65-<75 and ≥75 years and for the overall population. RESULTS: A total of 371 patients with squamous NSCLC were enrolled at 96 centres between April 2015 and September 2015; 34% (n = 126), 47% (n = 175) and 19% (n = 70) were aged <65, 65-<75 and ≥75 years, respectively. Efficacy was similar among patients aged <65, 65-<75 and ≥75 years and the overall population (objective response rates: 18%, 18%, 19% and 18%, respectively; disease control rates: 49%, 47%, 43% and 47%, respectively). Median overall survival was reduced in patients aged ≥75 years (5.8 months) versus patients aged <65; years (8.6 months), patients aged 65-<75 years (8.0 months) and the overall population (7.9 months). The incidence of grade 3-4 treatment-related AEs was low in patients aged 65, 65-<75 and ≥75 years and the overall population (3%, 9%, 3%, 6%, respectively). Discontinuation rates due to treatment-related AEs were low irrespective of age (4-5%). CONCLUSIONS: These EAP results suggest that elderly patients with advanced squamous NSCLC benefit from nivolumab, with tolerability similar to that in the overall population.

BACKGROUND: Results from phase III clinical trial CheckMate 025 have established nivolumab as the standard of care for treatment of metastatic renal-cell carcinoma (mRCC) after VEGF inhibitor failure; however, elderly patients are under-represented in the registration trial and little is known about the activity of nivolumab in this subgroup. The purpose of the Expanded Access Program was to provide nivolumab to patients with mRCC who had progressed despite treatment with other agents that were considered standard of care. METHODS: Nivolumab 3 mg/kg was administered intravenously every 2 weeks to a maximum of 24 months or until progression or unacceptable toxicity. The current analysis included all patients from the EAP Italian cohort who had received ≥1 dose of nivolumab. Adverse events (AEs) were monitored using Common Terminology Criteria for Adverse Events v4.0. RESULTS: A total of 389 patients with advanced RCC were enrolled in the Italian cohort of the EAP and treated with nivolumab. Of these patients, 125 (32%) were at least 70 years of age and 70 (18%) were at least 75 years of age. Efficacy with nivolumab in the elderly patients was similar to that observed in the overall EAP population and in the CheckMate 025 trial. Safety was comparable between the elderly patients and the overall EAP population, and was consistent with what previously reported. CONCLUSION: The final results suggest that elderly patients with pretreated metastatic RCC may benefit from therapy with nivolumab.

The aim of this work is to assess if cumulative dose (CD) and dose intensity (DI) of everolimus may affect survival of advanced pancreatic neuroendocrine tumors (PNETs) patients. One hundred and sixteen patients (62 males and 54 females, median age 55 years) with advanced PNETs were treated with everolimus for ≥3 months. According to a Receiver operating characteristics (ROC) analysis, patients were stratified into two groups, with CD ≤ 3000 mg (Group A; n = 68) and CD > 3000 mg (Group B; n = 48). The response rate and toxicity were comparable in the two groups. However, patients in group A experienced more dose modifications than patients in group B. Median OS was 24 months in Group A while in Group B it was not reached (HR: 26.9; 95% CI: 11.0-76.7; P < 0.0001). Patients who maintained a DI higher than 9 mg/day experienced a significantly longer OS and experienced a trend to higher response rate. Overall, our study results showed that both CD and DI of everolimus play a prognostic role for patients with advanced PNETs treated with everolimus. This should prompt efforts to continue everolimus administration in responsive patients up to at least 3000 mg despite delays or temporary interruptions.

PURPOSE: To investigate the prognostic role of thymidylate synthase (TS) polymorphisms in gastric cancer patients treated with radical surgery and fluorouracil-based adjuvant chemotherapy. EXPERIMENTAL DESIGN: Ninety gastric cancer cases were identified among 187 patients previously enrolled in prospective case-control studies for disease susceptibility. Patients were genotyped for a G/C nucleotide change within a triple 28 bp variable number of tandem repeat sequence in the TS 5'-untranslated region (5'-UTR) and a 6 bp deletion in the TS 3'-untranslated region (3'-UTR). According to available functional data, patients with 5'-UTR 2R/2R, 2R/3C, 3C/3C genotypes were classified as low TS producers (5'-UTRlow) and patients with 5'-UTR 3G/3G, 3G/3C, 2R/3G genotypes as high TS producers (5'UTRhigh). Patients with 3'-UTR del6/del6 and del6/ins6 genotypes were classified as low TS producers (3'-UTRlow) and patients with 3'-UTR ins6/ins6 genotype as high TS producers (3'-UTRhigh). The prognostic analysis was based on 5'-UTR/3'-UTR combined genotypes. RESULTS: Ten patients (11%) were 5'-UTRhigh/3'-UTRhigh, 36 patients were 5'-UTRhigh/3'-UTRlow, 19 patients were 5'-UTRlow/3'-UTRhigh, and 25 patients were 5'-UTRlow/3'-UTRlow. 5'-UTRlow/3'-UTRlow patients showed the best outcome and the threshold of statistical significance was achieved in the comparison of disease-free survival and overall survival with 5'-UTRhigh/3'-UTRlow patients and 5'-UTRhigh/3'-UTRhigh patients. The presence of at least one high TS expression genotype showed independent adverse prognostic role in multivariate analysis. CONCLUSIONS: The prognostic role of TS polymorphisms in gastric cancer deserves further investigation because the adverse effect of high TS expression genotypes may be a relevant information to improve adjuvant chemotherapeutic strategies.

BACKGROUND: The aim of this report is related to adult primary paratesticular mesenchymal tumors with emphasis on a case presentation and discussion of the spermatic cord leiomyosarcoma. Primary paratesticular tumors are rare, only accounting for 7% to 10% of all intrascrotal tumors. In adults, more than 75% of these lesions arise from the spermatic cord, 20% being leiomyosarcoma. Tumor grade, stage, histologic type, and lymph node involvement are independently predictive of prognosis. FINDINGS: The case report concerns a 81-year-old man presented with a 3-year history of painless lump in the right hemiscrotum. Scrotal examination demonstrated a 5.1-cm, firm-to-hard mass attached to the spermatic cord. Scrotal ultrasound scan revealed a heterogeneous mass separate from the testis. He was treated with an radical orchi-funicolectomy. Histologically the lesion is composed of spindled cells with often elongated, blunt-ended nuclei and variably eosinophilic cytoplasm. Areas with pleomorphic morphology are present. The level of mitotic activity is equal to 3/10 HPF in the areas with spindle cell morphology and to 12/10 HPF in the areas with pleomorphic morphology. The final diagnosis was that a leiomyosarcoma of the spermatic cord, with grade 1 and grade 2 areas, stage pT2b cN0 and cM0. The patient has been followed up for 3 months with CT scans and shows no signs of recurrence. CONCLUSIONS: Spermatic cord leiomyosarcoma, although rare, should be one of the first differential diagnoses for a firm-to-hard lump in the cord. Apart from radical orchi-funicolectomy, there has been added benefit of adjuvant radiotherapy to prevent any loco-regional lymph node recurrence.

AIMS AND BACKGROUND: In recent years, the number of oral anticancer drugs used in clinical practice has rapidly increased. The Italian Society of Medical Oncology (AIOM) conducted a survey to describe the impact of the use of oral anticancer drugs on the daily activity of Italian oncology practices. METHODS AND STUDY DESIGN: A survey questionnaire was distributed to the coordinators of the regional sections of AIOM. A 6-month period was considered, from January 1, 2010 to June 30, 2010. The survey addressed (1) quantitative aspects of the use of oral anticancer drugs; (2) practical aspects in the management of patients treated with these drugs; (3) issues related to treatment costs and reimbursement procedures. RESULTS: Thirty-six questionnaires were received from institutions distributed throughout the Italian territory. Oral anticancer drugs (both chemotherapy and molecularly targeted agents) accounted for a significant proportion (17%) of prescribed treatments. Among the responding institutions, there were different dispensation procedures of oral drugs to patients: drugs were dispensed by the pharmacist (57%) or directly by the medical oncologist (23%) or nurse (20%). The medical oncologist played a major role in the communication with patients (73% alone and a further 24% in cooperation with other professional figures) and was the point of reference in the event of side effects in 97% of cases. In most cases, the reimbursement of drug costs was separated ("File F" procedure) from the flat fare received by the hospital for outpatient visits or day-hospital access. CONCLUSIONS: Optimal organization of oral anticancer treatment warrants the cooperation and integration of multiple professional figures. At least three figures are involved in patient management in the hospital: the medical oncologist, the nurse, and the hospital pharmacist. Oral anticancer treatments are associated with specific reimbursement issues: in the majority of cases, the cost of the drug is reimbursed separately from the cost of patient access.

AIMS AND BACKGROUND: In 2009, the Italian Society of Medical Oncology (AIOM) conducted a survey to describe the impact of regional pharmaceutical formularies on the disparity of access to eight new drugs among cancer patients treated in Italian regions. The survey documented some regional restrictions for some anti-cancer drugs. In the study, we analyzed the "time to patient access" to new anti-cancer drugs in Italian regions. METHODS: In March 2010, we analyzed the availability of 17 new anti-cancer drugs at a regional level, specifically the coherence of regional authorizations compared with national authorizations approved by the Italian Medicines Agency (AIFA). In the regions with pharmaceutical formularies, we analyzed the characteristics of technical-scientific committees for the evaluation of inclusion of hospital drugs in these formularies. We also analyzed the time from EMA (CMPH) authorization to AIFA marketing authorization, the time from AIFA marketing authorization to patient availability, and the total time from EMA (CMPH) authorization to patient availability of the drugs in all Italian regions, for 11 of these drugs. RESULTS: Some drugs were included in all the regional pharmaceutical formularies, without restrictions, whereas other drugs were not included in one and others were not included in more than one formulary. Median time from EMA to AIFA was 11.2 months (range, 2.9-17.1). Median time from AIFA to patient availability was 1.4 months (range, 0.0-50.5) in regions with drug formularies versus 0.0 months in regions without drugs formularies. Median total time from EMA to patient availability was longer in regions with formularies (13.3 months; range, 2.9-65.3) than in regions without formularies (11.2 months; range, 2.9-24.0), where drugs are immediately available after AIFA marketing authorization. Moreover, the interval was very long (range, 2.9-65.3) for some drugs in regions with formularies. CONCLUSIONS: The analysis confirmed that the presence of multiple hierarchical levels of drug evaluation can create disparity in drug availability for Italian citizens.

PURPOSE: Regulation of epidermal growth factor receptor (EGFR) signaling pathways may play a relevant role in determining the activity of cetuximab therapy in patients with metastatic colorectal cancer (MCRC). We investigated possible associations between genetic variants and clinical outcomes of MCRC patients treated with cetuximab-irinotecan salvage therapy. PATIENTS AND METHODS: Patients who underwent cetuximab-irinotecan salvage therapy after disease progression during or after first-line bolus/infusional fluorouracil, leucovorin, and oxaliplatin chemotherapy and a second-line irinotecan-based regimen were considered eligible for analysis of polymorphisms with putative influence on cetuximab-related pathways. Epidermal growth factor (EGF) 61A>G, EGF receptor (EGFR) 216G>T, EGFR 497G>A, EGFR intron-1 (CA)(n) dinucleotide short (S)/long (L) variant, cyclin-D1 870A>G, immunoglobulin-G fragment-C receptors RIIIa 158G>T, and RIIa 131G>A were studied for a possible association with overall survival (OS) as the primary end point. Additional analyses were addressed at possible associations among polymorphisms and EGFR expression, toxicity, and response. RESULTS: In 110 assessable patients, significant association with favorable OS was observed for EGFR intron-1 S/S and EGF 61 G/G genotypes. In the multivariate model, EGFR intron-1 S/S and EGF 61 G/G genotypes showed a hazard ratio of 0.41 (95% CI, 0.21 to 0.78; P = .006) and 0.44 (95% CI, 0.23 to 0.84; P = .01), respectively. EGFR intron-1 S/S carriers showed more frequent G2-G3 skin toxicity (chi(2) test = 12.7; P = .001) and treatment response (chi(2) test = 9.45; P = .008) than EGFR intron-1 L/L carriers. CONCLUSION: Although additional studies are required for confirmation, our findings could optimize the use of cetuximab in MCRC patients.

BACKGROUND: Gastric cancer is the second highest cause of cancer mortality in the world, despite declining rates of incidence in many industrialized countries. We carried out a case-control study to evaluate whether polymorphisms of DNA repair and glutathione S-transferase (GST) genes modulate the risk of developing diffuse gastric cancer. METHODS: ERCC1 118 T/C, XRCC1 399 G/A, XPD 312 G/A, XPD 751 A/C, XRCC3 241 C/T, MS 919 A/G, GSTP1 105 A/G, GSTM1-null/positive and GSTT1-null/positive genotypes were obtained for a series of 126 Helicobacter pylori-negative diffuse gastric cancer patients and 144 Helicobacter pylori-negative controls sampled from the population of Marche, an area with high gastric cancer risk in central Italy. RESULTS: GSTP1 105 A/G and GSTP1 105 G/G genotypes were identified as protective factors, with odds ratio (OR) of 0.4 (95% CI 0.17-0.81, p=0.01) and OR=0.58 (95% CI 0.33-1, p=0.05), respectively. GSTT1-null genotype was identified as a protective factor, with OR=0.48 (95% CI 0.22-0.99, p=0.04). There was no significant difference between cases and controls for XPD 751 A/C, ERCC1 118 T/C, XRCC3 241 C/T, XRCC1 399 G/A, XPD 312 G/A, GSTM1-null/positive and MS 919 A/G polymorphisms. CONCLUSIONS: This study suggests that GSTP1 105A/G and GSTT1-null/positive genotypes might be associated with a reduced risk for sporadic diffuse gastric cancer. Clin Chem Lab Med 2007;45:822-8.

INTRODUCTION: This study's aim was to assess economic data regarding the home assistance burden for advanced non-small cell lung cancer (NSCLC) patients in Italy. PATIENTS AND METHODS: One hundred four NSCLC patients in second-line chemotherapy (2LC) or in supportive therapy (ST) were enrolled in 18 Italian oncology departments and were observed for 3 months. The main caregiver's workload was assessed monthly by a task scale; other caregivers' activities were also registered. Eastern Cooperative Oncology Group performance status was assessed by physicians, and patients completed the Lung Cancer Symptoms (LCS) subscale. Formal caregiving time was valued according to market prices; informal caregiving hours were valued using the wage rate for an equivalent service. Covariance analysis was performed to check for influential factors in assistance costs. RESULTS: The mean age of the total sample was 65.5 years, and prevalence of males was over 80%. In over 70% of cases, the principal caregiver was patient's spouse, living with the patient and not working. Principal caregiver support was the main cost item: 2.368 euros in 2LC and 2.805 euros in ST, representing 74% of total trimonthly assistance costs. Regression analysis showed a positive correlation between the severity of symptoms and the costs of assistance. The caregiving burden was higher in patients with bone and/or cerebral metastases; other metastasis sites seemed to have no impact on assistance costs. CONCLUSION: Considering quality of life as the ultimate health outcome, clinicians are challenged to contribute to a research and policy agenda that holds burden of care in due consideration.

PURPOSE: The objective is to investigate whether polymorphisms with putative influence on fluorouracil/oxaliplatin activity are associated with clinical outcomes of patients with advanced colorectal cancer treated with first-line oxaliplatin, folinic acid, and fluorouracil palliative chemotherapy. MATERIALS AND METHODS: Consecutive patients were prospectively enrolled onto medical oncology units in Central Italy. Patients were required to have cytologically/histologically confirmed metastatic disease with at least one measurable lesion. Peripheral blood samples were used for genotyping 12 polymorphisms in thymidylate synthase, methylenetetrahydrofolate reductase, xeroderma pigmentosum group D (XPD), excision repair cross complementing group 1 (ERCC1), x-ray cross complementing group 1, x-ray cross complementing protein 3, glutathione S-transferases (GSTs) genes. The primary end point of the study was to investigate the association between genotypes and progression-free survival (PFS). RESULTS: In 166 patients, ERCC1-118 T/T, XPD-751 A/C, and XPD-751 C/C genotypes were independently associated with adverse PFS. The presence of two risk genotypes (ERCC1-118 T/T combined with either XPD-751 A/C or XPD-751 C/C) occurred in 50 patients (31%). This profiling showed an independent role for unfavorable PFS with a hazard ratio of 2.84% and 95% CI of 1.47 to 5.45 (P = .002). Neurotoxicity was significantly associated with GSTP1-105 A/G. Carriers of the GSTP1-105 G/G genotype were more prone to suffer from grade 3 neurotoxicity than carriers of GSTP1-105 A/G and GSTP1-105 A/A genotypes. CONCLUSION: A pharmacogenetic approach may be an innovative strategy for optimizing palliative chemotherapy in patients with advanced colorectal cancer. These findings deserve confirmation in additional prospective studies.

PURPOSE: To investigate whether polymorphisms with putative influence on fluorouracil/cisplatin activity are associated with clinical outcomes of patients with advanced gastric cancer (AGC). PATIENTS AND METHODS: Peripheral blood samples from 175 prospectively enrolled AGC patients treated with fluorouracil/cisplatin palliative chemotherapy were used for genotyping 13 polymorphisms in nine genes (TS, MTHFR, XPD, ERCC1, XRCC1, XRCC3, GSTPI, GSTTI, GSTMI). Genotypes were correlated to response and survival. RESULTS: The overall response rate was 41%, the median progression-free survival (PFS) was 24 weeks (range, 4 to 50 weeks), and the median overall survival (OS) was 39 weeks (range, 8 to 72+ weeks). Chemoresistance and poor survival were significantly associated with TS 5'-UTR 3G-genotype (2R/3G, 3C/3G, 3G/3G) and GSTP1 105 A/A homozygous genotype. Sixty-one patients (35%) did not show any of these risk genotypes (group 0), 57 patients (32.5%) showed one of the two risk genotypes (group 1), and 57 patients (32.5%) showed both risk genotypes (group 2). Median PFS and OS in group 0 patients were 32 weeks (range, 8 to 50 weeks) and 49 weeks (range, 18 to 72+ weeks), respectively. Group 1 and group 2 patients showed significantly worse PFS (median, 26 weeks [range, 6 to 44 weeks] and 14 weeks [range, 4 to 38 weeks], respectively) and worse OS (median, 39 weeks [range, 10 to 58 weeks] and 28 weeks [range, 8 to 56 weeks]), respectively, than group 0 patients. This adverse effect was retained in multivariate analysis. CONCLUSION: Specific polymorphisms may influence clinical outcomes of AGC patients. Selecting palliative chemotherapy on the basis of pretreatment genotyping may represent an innovative strategy that warrants prospective studies.

We performed a case-control study to examine the relationship between MTHFR C677T gene polymorphism (MTHFR677C/T) and gastric cancer susceptibility in at-risk populations in central Italy. To explore genomic DNA hypomethylation as a potential etiologic mechanism, this phenomenon was evaluated in carriers of the MTHFR677T/T genotype and carriers of the wild-type MTHFR677C/C genotype. Lymphocyte genomic DNA from 162 gastric cancer patients and 164 controls was used for MTHFR677C/T genotyping. Unconditional regression analysis with ORs and 95% CIs was used to investigate the association of the polymorphism with disease. Genomic DNA methylation status by an established enzymatic assay that measures the DNA accepting capacity of methyl groups (inversely related to endogenous methylation) was assessed in a random sample of 40 carriers of the wild-type MTHFR677C/C genotype and 40 carriers of the MTHFR677T/T genotype. The global allelic distribution was in Hardy-Weinberg equilibrium. The MTHFR677T allele was significantly associated with gastric cancer risk with an OR of 2.49 (95% CI 1.48-4.20) in heterozygous MTHFR677C/T carriers and an OR of 2.85 (95% CI 1.52-5.35) in homozygous MTHFR677T/T carriers. This risk association was retained in subgroup analyses by tumor histotype and location. Genomic DNA hypomethylation status in MTHFR677T/T carriers was significantly higher than in subjects with wild-type MTHF677C/C genotype (p = 0.012). In the studied population, MTHFR677T played the role of a moderate-penetrance gastric cancer susceptibility allele. Possession of the MTHFR677T/T genotype was significantly associated with genomic DNA hypomethylation. These findings deserve further investigation in the context of novel strategies for gastric cancer prevention.
