Cancer patient perspective in the arena of COVID-19 pandemic.

OBJECTIVE: The coronavirus disease 2019 (COVID-19) outbreak has been declared a global pandemic of unprecedented proportions. Italy is a country which has been heavily affected. Cancer patients are at a higher risk owing to their intrinsic fragility related to their underlying disease and oncologic treatment. Against this backdrop, we conducted a survey to investigate how patients perceived their condition, clinical management and availability of information during the pandemic. METHODS: Between 15 April and 1 May 2020 a survey was submitted to cancer patients at oncology departments in the Marche region. Questions regarding the perception of personal safety, continuity of cancer care, information quality and psychological distress. RESULTS: Seven hundred patients participated in the survey; 59% were female and 40% were aged between 46 and 65. The majority of the participants perceived compliance with appropriate safety standards by cancer care providers and 80% were reassured about their concerns during the medical interview. 40% were worried of being at a higher risk of infection and 71% felt they were at a greater risk because of chemotherapy. 55% felt that postponing cancer treatment could reduce its efficacy, however 76% declared they did not feel abandoned at the time of treatment postponement. Patients between 46 and 65 years declared a significant reduction in sleep (p < 0.01) and in concentration (p = 0.03). CONCLUSIONS: The emergency care offered to cancer patients has been deemed satisfactory in terms of both safety standards and care management. However, the majority of participants perceived the mutual negative influence between their oncologic disease and the risk of infection highlighting the need for special measures to ensure safe continuity of care.

A phase II study of modified FOLFOX as first-line chemotherapy for metastatic gastric cancer in elderly patients with associated diseases.

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).

Impact of Signet-Ring Cell Histology in the Management of Patients with Non-Metastatic Gastric Cancer: Results from a Retrospective Multicenter Analysis Comparing FLOT Perioperative Chemotherapy vs. Surgery Followed by Adjuvant Chemotherapy.

BACKGROUND: FLOT perioperative chemotherapy represents the standard of care in non-metastatic gastric cancer patients. Signet-ring cell positivity is associated with a worse prognosis in patients with gastric cancer treated with chemotherapy. Comparison between FLOT perioperative chemotherapy vs. surgery followed by adjuvant chemotherapy based on signet-ring cell positivity is lacking. The aim of the analysis was to compare perioperative FLOT with adjuvant chemotherapy in gastric cancer patients stratified by signet-ring cell positivity. METHODS: We conducted a retrospective multicenter analysis based on disease-free survival (DFS) and overall survival (OS) in patients with gastric cancer who received perioperative chemotherapy with a FLOT regimen and compared their survival with a historical cohort of patients treated with adjuvant chemotherapy, matched by cT and cN stage and by tumor histological features. RESULTS: Seventy-six patients were enrolled and 24 (32%) were signet-ring cell positive. At a median follow-up time of 39 months, the median DFS was 26.3 months and the median OS was 37.3 months. Signet-ring cell positivity was associated with a shorter OS (median OS: 20.4 vs. 46.9 months, HR: 3.30, 95%CI: 1.56-6.99, p = 0.0018) and DFS (mDFS: 15.2 vs. 38.6 months, HR: 3.18, 95%CI: 1.55-6.54, p = 0.0016). This was confirmed by multivariate analysis for DFS (Exp(B): 2.55) and OS (Exp(B): 2.68). After propensity score matching, statistically significant shorter DFS (HR: 3.30, 95%CI: 1.50-7.35, p = 0.003) and OS (HR: 5.25, 95%CI: 2.18-12-68, p = 0.0002) were observed for patients with signet-ring cell positivity who received perioperative treatment vs. those who received surgery followed by adjuvant chemotherapy. CONCLUSIONS: Signet-ring positivity was associated with shorter DFS and OS in patients who received perioperative treatment with FLOT compared with surgery followed by adjuvant therapy. These data suggest that for patients with signet-ring cell histology, FLOT perioperative treatment might not always be the best choice of treatment, and further research should be focused on this group of patients.

Sequential chemotherapy with cisplatin, leucovorin, and 5-fluorouracil followed by docetaxel in previously untreated patients with metastatic gastric cancer: a phase II study.

BACKGROUND: The combination of docetaxel, cisplatin, and 5-fluorouracil (5-FU) has demonstrated a survival advantage over cisplatin and 5-FU, but with substantial hematological toxicity. We aimed to evaluate the efficacy and toxicity of a sequential regimen with cisplatin, leucovorin, and 5-FU (PLF) followed by docetaxel in metastatic gastric cancer patients. METHODS: Treatment consisted of 4 cycles of biweekly PLF (cisplatin 50 mg/m(2) as a 30-min infusion on day 1, leucovorin 200 mg/m(2) in a 2-h infusion, and 5-FU 2,800 mg/m(2) in a 48-h continuous infusion starting on day 1) followed, in cases of response or stable disease, by 3 cycles of docetaxel (75 mg/m(2), every 3 weeks). RESULTS: Thirty-four patients were enrolled, with an average age of 64 years (range 34-69). The main cumulative grade 3-4 toxicities were: neutropenia (38.2%), febrile neutropenia (11.8%), and fatigue (14.7%). After the planned 7 cycles of treatment, the overall response rate was 38.2% (95% confidence interval [CI] 21.9-54.6), with 3 complete and 10 partial responses. Median progression-free survival and overall survival were 4.8 and 10.6 months, respectively. CONCLUSIONS: For patients with metastatic gastric cancer, the sequential administration of cisplatin, leucovorin, 5-FU, and docetaxel may be an effective palliative option and offers a far more favorable toxicity profile than the simultaneous use of docetaxel, cisplatin, and 5-FU.

HtrA1, a potential predictor of response to cisplatin-based combination chemotherapy in gastric cancer.

AIMS: HtrA1 is a member of the HtrA (high-temperature requirement factor A) family of serine proteases. HtrA1 plays a protective role in various malignancies due to its tumour suppressive properties. The aim of this study was to determine HtrA1 expression as a predictor of chemoresponse in patients with advanced gastric cancer. METHODS AND RESULTS: HtrA1 expression was determined by immunohistochemistry on specimens of primary gastric cancer from 80 patients treated consecutively with cisplatin-based combination chemotherapy. Response to chemotherapy was assessed according to Response Evaluation Criteria in Solid Tumours (RECIST) criteria. Our population consisted of males/females [51/29; median age 64 years (range 32-82)]. A complete or partial response was observed in 71.4% [95% confidence interval (CI) 54.7-88.2], 66.7% (95% CI 47.8-85.5) and 28.6% (95 CI 11.8-45.3) of tumours showing high, medium and low HtrA1 expression, respectively. A statistically significant association between HtrA1 expression and the clinical response was observed (P = 0.002). The median overall survival for patients with high/medium expression was 17 months compared to 9.5 months for patients with low HtrA1 expression (P = 0.037). CONCLUSIONS: Identification of HtrA1 in gastric cancer prior to chemotherapy indicates that levels of HtrA1 could be used to predict response to platinum-based combination therapies. Further assessment of HtrA1 expression is highly warranted in large, prospective studies.

Metronomic Oral Vinorelbine: An Alternative Schedule in Elderly and Patients PS2 With Local/Advanced and Metastatic NSCLC Not Oncogene-addicted.

BACKGROUND: The MILES and ELVIS studies showed that vinorelbine is one of the best options for elderly patients with advanced non-small-cell-lung cancer (NSCLC). Oral vinorelbine at standard schedule (60-80 mg/m2/weekly) has good activity in terms of response rates and progression-free survival. In recent years, a metronomic schedule of oral vinorelbine (40-50 mg/m2 three times a week, continuously) has been studied in phase II trials, especially in unfit and elderly patients. In the MOVE trial metronomic oral vinorelbine had a clinical benefit [partial response (PR)+stable disease (SD) >12 weeks] in 58.1% of patients with mild toxicity. On this basis, in 2017 we started a phase II study with metronomic oral vinorelbine in elderly (over 70 years) or unfit [Eastern Cooperative Oncology Group performance score (ECOG-PS) of 2] patients with locally/advanced and metastatic NSCLC. Primary aims were clinical benefit (PR+SD ≥6 months) and toxicity; secondary aims were progression-free survival and overall survival. PATIENTS AND METHODS: A total of 25 patients entered the study: 11 with local/advanced and 14 with metastatic NSCLC (five squamous and 20 adenocarcinoma). None of the patients had epidermal growth factor receptor (EGFR) mutations, anaplastic lymphoma kinase (ALK) translocation, or programmed death ligand 1 (PDL1) expression; those with squamous carcinoma did not have PDL1 expression. The median age was 79 (range=44-90) years. The PS was 0 in 12 patients (48%), 1 in four patients (16%) and 2 in nine patients (36%). Oral vinorelbine was administered at 40 mg three times a week continuously. RESULTS: Clinical benefit was achieved in eight patients (32%). Objective responses were partial response in two patients (8%), stable disease in seven (28%), progressive disease in nine (36%); seven patients were not evaluable for response (28%). Median progression-free survival was 2 months; median overall survival was 4 months but four out of eight patients with clinical benefit were still alive at 18 months. Overall survival at 1 year was 32%. Toxicity was mild: only one patient experienced grade 4 neutropenia, one grade 3 peripheral neuropathy, four grade 2 asthenia, one grade 2 mucositis, and one grade 2 diarrhoea. The dose needed to be reduced to 30 mg/m2/three times a week in three patients. CONCLUSION: Our study confirmed the activity and safety of metronomic oral vinorelbine in patients with wild-type local/advanced and metastatic NSCLC unsuitable for treatment with standard i.v. chemotherapy, allowing patients a comfortable home-based therapy, thereby avoiding frequent hospital visits.

Clinical impact of first-line bevacizumab plus chemotherapy in metastatic colorectal cancer of mucinous histology: a multicenter, retrospective analysis on 685 patients.

PURPOSE: In metastatic colorectal cancer (MCRC), mucinous histology has been associated with poor response rate and prognosis. We investigated whether bevacizumab combined with different chemotherapy regimens may have an impact on clinical outcomes of MCRC patients with mucinous histology. METHODS: 685 MCRC patients were classified in mucinous adenocarcinoma (MC) and non-mucinous adenocarcinoma (NMC) and were treated with first-line bevacizumab plus fluoropyrimidine (FP)-based, oxaliplatin (OXA)-based, irinotecan (IRI)-based, or FOLFOXIRI. RESULTS: Ninety-four (13.7%) patients had MC. With a median follow-up of 50 months, MC patients had a median overall survival (OS) of 28.2 months compared with 27.7 months for the NMC group [hazard ratio (HR) = 0.92; 95% confidence interval (CI) 0.70-1.19, P = 0.530]. The overall response rates for MC and NMC were 41.5% (95% CI 31.5-51.4) and 62.4% (95% CI 58.4-66.3), respectively (Chi-square test, P <0.003). After correcting for significant prognostic factors by multivariate Cox regression analysis, age, resection of the primary tumour, and number of metastatic sites were found to be associated with poorer OS, but not mucinous histology. CONCLUSION: Compared with NMC, MCRC patients with mucinous histology treated with bevacizumab plus chemotherapy had comparable OS despite lower overall response rate.

TP53 Mutation Analysis in Gastric Cancer and Clinical Outcomes of Patients with Metastatic Disease Treated with Ramucirumab/Paclitaxel or Standard Chemotherapy.

Loss of p53 promotes vascular endothelial growth factor (VEGF)-A up-regulation and the angiogenic potential of cancer cells. We investigated TP53 somatic mutations in 110 primary gastric adenocarcinomas of two retrospective metastatic series including 48 patients treated with second-line Ramucirumab/Paclitaxel and 62 patients who received first-line chemotherapy with Cisplatin or Oxaliplatin plus 5-Fluorouracil. Missense mutations were classified by tumor protein p53 (TP53) mutant-specific residual transcriptional activity scores (TP53RTAS) and used to stratify patients into two groups: transcriptionally TP53Active and TP53Inactive. The primary endpoint was overall survival (OS). An additional analysis was addressed to measure VEGF/VEGF receptor 2 (VEGFR2) expression levels in relation to the TP53RTAS. In the Ramucirumab/Paclitaxel group, 29/48 (60.4%) patients had TP53 mutations. Ten patients with TP53Inactive mutations showed better OS than carriers of other TP53 mutations. This effect was retained in the multivariate model analysis (Hazard Ratio = 0.29, 95% confidence interval = 0.17-0.85, p = 0.02). In the chemotherapy group, 41/62 (66%) patients had TP53 mutations, and the 11 carriers of TP53Inactive mutations showed the worst OS (Hazard Ratio = 2.64, 95% confidence interval = 1.17-5.95, p = 0.02). VEGF-A mRNA expression levels were significantly increased in TP53Inactive cases. Further studies are warranted to explore the effect of TP53Inactive mutations in different anti-cancer regimens. This information would lead to new tailored therapy strategies for this lethal disease.

Weekly paclitaxel in elderly patients (aged > or = 70 years) with advanced non-small-cell lung cancer: an alternative choice? Results of a phase II study.

PURPOSE: Paclitaxel and platinum-based chemotherapy is considered to be a standard approach for locally advanced and metastatic non-small-cell lung cancer (NSCLC). In recent years, weekly paclitaxel has been widely used for its safety profile, especially in breast and ovarian cancer. Otherwise, only a few studies are available in NSCLC. The aim of our study was to investigate the activity and safety of weekly paclitaxel in elderly patients with locally advanced (stage IIIB) and metastatic (stage IV) NSCLC. PATIENTS AND METHODS: Twenty-seven patients entered the study; 10 had stage IIIB disease (5 "wet" and 5 "dry"), and 17 had stage IV disease. Median age was 73 years (range, 70-83 years). Sixteen patients (59%) presented with comorbidities. The schedule was weekly paclitaxel 80 mg/m2 for 6 weeks with 2 weeks of rest (1 cycle). RESULTS: All patients were evaluable for response and toxicity; a median of 1 cycle was administered (range, 1-5 cycles). Partial responses were recorded in 9 patients (37.5%; 33.3%, according to intention-to- treat analysis; 95% CI, 15.5%-51.1%); 7 had stable disease (29%), and 8 had progressive disease (33.5%). Median time to progression was 5 months (range, 1-23 months), and median survival was 12 months (range, 1-36 months). Grade 2/3 asthenia was the main toxicity in 7 patients (29%); a hypersensitivity reaction presented in 1 patient. No other episode of grade 3/4 toxicity was recorded. CONCLUSION: Our study confirmed that paclitaxel 80 mg/m2 weekly is active in patients with locally advanced and metastatic NSCLC with a good safety profile; this schedule might be considered an alternative choice to gemcitabine or vinorelbine as first-line treatment in elderly patients, particularly patients with comorbidities. Phase III studies that compare these third-generation drugs are warranted to draw definitive conclusion about the best approach in these patients.

Safety profile and activity of lower capecitabine dose in patients with metastatic breast cancer.

PURPOSE: Capecitabine is an orally administered precursor of 5'-deoxy-5-fluorouridine that was rationally designed to generate 5-fluorouracil (5-FU) preferentially in tumor tissue. The drug enables chronic dosing that mimics continuous infusion of 5-FU. Phase II trials of capecitabine at 1250 mg/m2 twice daily for 14 days followed by 7 days of rest, is active in anthracycline- and taxane-pretreated patients; the main toxicity is palmar-plantar erythrodysesthesia, diarrhea, and nausea. To overcome these side effects, the dose has been reduced to 1000 mg/m2 twice daily with a better therapeutic profile and encouraging efficacy. The aim of our study was to confirm safety and activity of capecitabine at lower doses in patients with metastatic breast cancer (MBC). PATIENTS AND METHODS: Thirty-seven patients with advanced breast cancer entered the study. The first 7 patients were treated with capecitabine 1250 mg/m2 twice daily (for 14 days followed by 7 days of rest) and the next 30 patients with capecitabine 1000 mg/m2. The median age was 62 years (range, 38-87 years). Thirteen patients were chemotherapy naive and 24 were pretreated with chemotherapy (9 patients, 1 line; 15 patients, > or = 2 lines). Anthracyclines and/or taxane schedules were administered in 22 patients. Soft tissue metastases were documented in 36 patients; visceral metastases in 24 patients; visceral and soft tissue metastases in 23 patients. RESULTS: Thirty patients were evaluable for response (5 at "higher" dose and 25 at "lower" dose) and all for toxicity. Overall objective response rate was 57% (5 complete responses and 12 partial responses); 95% CI, 39%-74%; stable disease 20% and progressive disease 23%. Eight of 13 chemotherapy-naive patients (61.5%) and 9 of 24 pretreated patients (37.5%) responded to capecitabine, according to the intent-to-treat principle (6 of 9 responses were obtained at a lower dose). Three responses at the "higher" dose and 14 at the "lower" dose were reported. Median time to progression was 7 months (range, 1-38 months) and median overall survival was 19 months (range, 2-47 months). Toxicity was as follows: grade 2/3 palmar-plantar erythrodysesthesia in 9 patients (24%), grade 2/3 asthenia in 7 patients (19%), grade 2 vomiting in 4 patients (11%), grade 2 renal toxicity in 1 patient, grade 2 skin reaction in 1 patient, and suspected cardiac toxicity in 1 patient. CONCLUSION: Our study confirmed that a lower dose of capecitabine has a good toxicity profile and is active in patients with MBC.

A phase II study of single-agent oral vinorelbine in patients with pretreated advanced non-small-cell lung cancer.

PURPOSE: Intravenous vinorelbine has demonstrated its efficacy and tolerability in advanced non-small-cell lung cancer (NSCLC). An oral formulation of vinorelbine has been developed, and a number of phase II studies have shown its activity in chemotherapy-naive NSCLC, even in elderly patients, but no study has been performed to test activity and toxicity of oral vinorelbine in pretreated patients. The aims of our study were to investigate the activity and toxicity of oral vinorelbine in patients with NSCLC as salvage treatment. PATIENTS AND METHODS: Twenty pretreated patients with locally advanced (n = 6) and metastatic (n = 14) NSCLC entered the study. The schedule was oral vinorelbine 60 mg/m(2) once a week until progression or development of unacceptable toxicity. Median age was 70 years (range, 49-84 years). RESULTS: Seventeen patients were evaluable for response and all for toxicity. A median of 9 cycles were administered (range, 2-21 cycles). No objective responses were reported, 5 patients experienced stable disease, and 12 patients had progressive disease. Median time to progression was 2 months (range, 1-6 months), and median survival was 4 months (range, 1-13 months). Treatment was well tolerated, with grade 4 neutropenia in 1 patient (heavily pretreated); grade 2 diarrhea in 2 patients; asthenia in 2 patients; and abdominal pain in 1 patient. CONCLUSION: Oral vinorelbine 60 mg/m(2) once a week is a very safe schedule in heavily pretreated locally advanced and metastatic NSCLC; however, at this dose, the drug is inactive. Other phase II studies with oral vinorelbine 80 mg/m(2) weekly are warranted.

Weekly docetaxel as second-line therapy in non-small cell lung cancer: a phase II study.

INTRODUCTION: Single-agent docetaxel is active as second-line chemotherapy in non-small cell lung cancer (NSCLC) pretreated patients; seven phase II studies have shown response rates of about 20% and 9 months of median survival. Two phase III studies documented a survival benefit at 1 year compared to BSC and vinorelbine or ifosfamide. Recent trials indicate acceptable activity and a good safety profile of weekly docetaxel with doses of 25-43 mg/m2. The aim of our study was to confirm this evidence and to evaluate activity and toxicity of weekly docetaxel at the dose of 40 mg/m2. PATIENTS ATND METHODS: Twenty-one patients with NSCLC entered the study (7 stage IIIB and 14 stage IV): 13 males and 8 females. Median age was 66 years (range, 53-75). ECOG was O in 6, 1 in 9 and 2 in 6 patients. All patients were pretreated with a first-line chemotherapy (13 patients progressed soon after the first line); 6 of them received palliative radiotherapy on the chest. The treatment consisted of weekly docetaxel, 40 mg/m2 in 1 hr for six weeks with two weeks of rest (1 cycle). A total of 87 administrations was delivered (median, 4; range, 1-12). RESPONSES: All patients were assessable for response (according to the "intent-to-treat principle") and for toxicity. No complete or partial remission was observed; 2 minor responses (9.5%), 1 stable disease (5%), 8 progressive diseases (38%) were documented. Seven patients dropped out the study due to severe toxicity (33.5%) and 3 due to early death (14%). Median survival was 3 months (range, 1-17), and 1-year survival was 9.5%. Toxicity was as follows: grade 4 diarrhea in 1; grade 3 asthenia in 8 (38%), grade 3 stomatitis in 2; grade 3 neutropenia in 1; allergic reactions in 2. No treatment-related death was recorded. CONCLUSIONS: The trial showed only very modest activity of weekly docetaxel, with severe side effects that induced us to stop the accrual in order to prevent other worse toxicities. We therefore concluded that a dose of 40 mg/m2 of weekly docetaxel is not manageable and does not seem to provide a real benefit in terms of response and quality of life.

Early and Complete Response of Bone Metastases, Documented by FDG-PET/CT Scan, in a Patient With NSCLC.

In this case report we describe the case of a patient with multiple bone metastases of NSCLC, adenocarcinoma with exon 21 point-mutation of EGFR, treated with gefitinib. After only 3 months, FDG-PET/CT scan showed a complete response of bone metastases and right hylar adenopathy. Implications for need of early use of FDG-PET/CT scan after gefitinib treatment are discussed.

High safety profile and activity of oral vinorelbine in an elderly patient with metastatic breast cancer.

Visceral metastases of breast cancer have been commonly treated with "aggressive" anthracyclines/taxanes-based chemotherapy. In contrast, this case report concerns an elderly patient with advanced breast cancer (pleural effusion, peritoneal carcinosis, and bone metastases) who firmly declined intravenous chemotherapy and was treated for a long time (28 months) with oral vinorelbine. The oral formulation of this drug had activity and a high safety profile, enabling the patient's wishes to be respected.

Intra-arterial infusion of irinotecan-loaded drug-eluting beads (DEBIRI) versus intravenous therapy (FOLFIRI) for hepatic metastases from colorectal cancer: final results of a phase III study.

BACKGROUND: Metastases to the liver receive most of their blood supply from the arterial route, therefore for patients with hepatic metastases from large bowel cancer, hepatic arterial infusion adopting drug-eluting beads preloaded with irinotecan (DEBIRI) may offer a chance of cure. PATIENTS AND METHODS: In a multi-institutional study, 74 patients were randomly assigned to receive DEBIRI (36) versus systemic irinotecan, fluorouracil and leucovorin (FOLFIRI, 38). The primary end-point was survival; secondary end points were response, recurrence, toxicity, quality of life, cost and influence of molecular markers. RESULTS: At 50 months, overall survival was significantly longer for patients treated with DEBIRI than for those treated with FOLFIRI (p=0.031, log-rank). Median survival was 22 (95% Confidence Interval CI=21-23) months, for DEBIRI and 15 (95% CI=12-18) months for FOLFIRI. Progression-free survival was 7 (95% CI=3-11) months in the DEBIRI group compared to 4 (95% CI=3-5) months in the FOLFIRI group and the difference between groups was statistically significant (p=0.006, log-rank). Extrahepatic progression had occurred in all patients by the end of the study, at a median time of 13 (95% CI=10-16) months in the DEBIRI group compared to 9 (95% CI 5-13) months in the FOLFIRI group. A statistically significant difference between groups was not observed (p=0.064, log-rank).The median time for duration of improvement to quality of life was 8 (95% CI=3-13) months in the DEBIRI group and 3 (95% CI=2-4) months in the FOLFIRI group. The difference in duration of improvement was statistically significant (p=0.00002, log-rank). CONCLUSION: This study showed a statistically significant difference between DEBIRI and FOLFIRI for overall survival (7 months), progression-free survival (3 months) and quality of life (5 months). In addition, a clinically significant improvement in time to extrahepatic progression (4 months) was observed for DEBIRI, a reversal of the expectation for a regional treatment. This suggests a benefit of DEBIRI treatment over standard chemotherapy and serves to establish the expected difference between these two treatment options for planning future large randomized studies.

Activity and safety of erlotinib as second- and third-line treatment in elderly patients with advanced non-small cell lung cancer: a phase II trial.

Erlotinib is an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor. Efficacy of this drug was documented in the BR.21 trial showing that adenocarcinoma, female gender, Asian ethnicity and never-smoker status are predictive of clinical response to erlotinib. Retrospective studies documented the same benefits for elderly patients as young patients in terms of response, progression-free survival, and overall survival. The primary aim of our trial was to confirm these findings in a prospective way; the secondary aim was to identify if the aforementioned clinical characteristics may be predictive of response even in elderly patients. The trial included 31 patients with pretreated stage IIIB (2) and IV (29) non-small cell lung cancer (NSCLC). Median age was 75 years (range: 65-85). Twenty-seven patients were current/former-smokers and four never-smokers. Twenty-three patients are evaluable for response. Objective response rates were reported in five patients (16%). Five patients had stable disease (16%) and 13 progressive disease (43%). Seven patients had a "clinical benefit" from erlotinib (22.5%; 95% C.I.: 7.9-37.2%). Grade 3 skin rash was recorded in three patients (10%). Median survival was 9 months (range 1-30). Median time to progression was 3 months (range: 1-24 months). Our study confirmed erlotinib activity and safety as second- and third-line treatment in elderly patients with advanced NSCLC, especially in terms of median survival. Even though this trial does not allow us to draw a definitive conclusion about the role of a particular clinical characteristic predictive of response, the "clinical benefit" was documented especially in females, in patients with adenocarcinoma histology and skin rash, confirming previous retrospective data.

Host genetic variants in the IGF binding protein-3 impact on survival of patients with advanced gastric cancer treated with palliative chemotherapy.

AIM: IGF binding protein-3 (IGFBP-3) displays growth inhibitory/proapoptotic action and counteracts the IGF-1 tumor-promoting effects by downregulating its bioavailability. We investigated whether IGFBP-3 SNPs determining high IGFBP-3 circulating levels are associated with improved survival of patients with advanced gastric cancer treated with palliative chemotherapy. MATERIALS & METHODS: A total of 185 patients undergoing combination chemotherapy for relapsed/metastatic disease were considered eligible for the present clinical investigation. Four functional IGFBP-3 SNPs (rs3110697, rs2854746, rs2864744 and rs2960436) were studied for association with overall survival (OS). RESULTS: In the multivariate model including SNPs and clinicopathologic features, the rs285744 A allele and the rs2960436 A allele showed favorable association with survival. The hazard ratios for rs285744 C/A and A/A genotypes were 0.38 (95% CI: 0.18-0.66) and 0.20 (95% CI: 0.09-0.39), respectively. The hazard ratios for rs2960436 G/A and A/A genotypes were 0.41 (95% CI: 0.25-0.68) and 0.35 (95% CI: 0.16-0.58), respectively. Bonferroni-corrected p-values for the rs285744 A/A genotype and the rs2960436 A/A genotype were 0.012 and 0.024, respectively. There was linkage disequilibrium between the four variants and there were four common haplotypes (>5% estimated frequency). The most common haplotype (GCAA) included all alleles causing IGFBP-3 upregulation and their carriers demonstrated the best outcome in the log-rank comparison of survival curves. CONCLUSION: Genetic regulation of the IGFBP-3 impacts on survival of patients with advanced gastric cancer. This finding deserves additional studies because of its prognostic and therapeutic implications.

Neoadjuvant chemotherapy with low dose of pegylated liposomal doxorubicin plus weekly paclitaxel in operable and locally advanced breast cancer.

To determine the activity and safety of a schedule with a low dose of pegylated liposomal doxorubicin (PLD) and weekly paclitaxel in operable and locally advanced breast cancer patients. Thirty-five patients with histologically confirmed, operable, and locally advanced breast cancer entered the study. The median age was 59 years (range 31-74 years). The schedule was biweekly PLD at the dose of 15 mg/m for four administrations and weekly paclitaxel at the dose of 80 mg/m for eight administrations. All patients were evaluable for response and toxicity. Twenty-six patients responded (74%): three (8%) had a complete response and 23 (66%) had a partial response, seven (23%) remained stable, and one experienced progression (3%). Fifteen of 27 operable patients (55%) underwent conservative surgery. Three patients (9%) had a pathological complete response and the disappearance of infiltrating disease was documented in three other patients. The main toxicity was hand-foot syndrome (grade 3 in four patients; 11%). Other nonhematological grade 3 toxicities included stomatitis in three patients (8%) and liver toxicity in one patient (3%). Grade 3-4 neutropenia was documented in another three patients and dose reduction was necessary in two patients. The fourth administration of PLD was suspended in four patients for grade 2-3 hand-foot syndrome. No symptoms were related to impairment of cardiac function and no death related to toxicity occurred. The combination of biweekly PLD and weekly paclitaxel was active in operable and locally advanced breast cancer with a manageable safety profile.

Intratumoural FOXP3-positive regulatory T cells are associated with adverse prognosis in radically resected gastric cancer.

We investigated the clinical significance of tumour-infiltrating FOXP3-positive regulatory T cells (Tregs) in radically resected (R0) gastric cancer. From a single-institution database, tumors of 110 patients who underwent R0 resection for stage II-III disease were studied for FOXP3-positive Tregs by immunohistochemistry. The observed median number of FOXP3-positive Tregs was used as the cut-point in analyses (<6 versus >or=6 count). Tregs were significantly higher in gastric carcinomas than in normal tissue (P = 0.0001). Tregs count >or=6 was significantly associated with vascular/lymphatic/perineural invasion (VELIPI) in the tumour (P = 0.03). Multivariate analysis showed association between adverse relapse-free survival and grading 3, stage III, VELIPI and Tregs count >or=6 (P = 0.02). Adverse overall survival was associated with grading 3, stage III, VELIPI and Tregs count >or=6 (P = 0.006). FOXP3-positive Tregs may be a novel marker for identifying high-risk gastric cancer patients. Present findings deserve additional investigation as Tregs may also represent an innovative therapeutic target.
