RESUMEN
BACKGROUND: The Patient Reported Outcome for Fighting FInancial Toxicity (PROFFIT) questionnaire was developed to measure financial toxicity (FT) and identify its determinants. The aim of the present study was to confirm its validity in a prospective cohort of patients receiving anticancer treatment. PATIENTS AND METHODS: From March 2021 to July 2022, 221 patients were enrolled at 10 Italian centres. Selected items of the EORTC-QLQ-C30 questionnaire represented the anchors, specifically, question 28 (Q-28) on financial difficulties, and questions 29-30 measuring global health status/quality of life (HR-QOL). The study had 80% power to detect a 0.20 correlation coefficient (r) between anchors and PROFFIT-score (items 1-7, range 0-100, 100 indicating maximum FT) with bilateral alpha 0.05 and 80% power. Confirmatory factor analysis was conducted. FT determinants (items 8-16) were described. RESULTS: Median age of patients was 65 years, 116 (52.5%) were females, 96 (43.4%) had low education level. Confirmatory factor analysis confirmed goodness of fit of the PROFFIT-score. Significant partial correlation of PROFFIT-score was found with Q-28 (r = 0.51) and HR-QOL (r = -0.23). Mean (SD) PROFFIT-score at baseline was 36.5 (24.9); it was statistically significantly higher for patients living in South Italy, those with lower education level, those who were freelancer/unemployed at diagnosis and those who reported significant economic impact from the COVID-19 pandemic. Mean (SD) scores of determinants ranged from 17.6 (27.1) for item 14 (support from medical staff) to 49.0 (36.3) for item 10 (expenses for medicines or supplements). PROFFIT-score significantly increased with worsening response to determinants. CONCLUSIONS: External validation of PROFFIT-score in an independent sample of patients was successful. The instrument is now being used in clinical studies.

BACKGROUND: Dihydropyrimidine dehydrogenase (DPD) catabolises â¼85% of the administered dose of fluoropyrimidines. Functional DPYD gene variants cause reduced/abrogated DPD activity. DPYD variants analysis may help for defining individual patients' risk of fluoropyrimidine-related severe toxicity. METHODS: The TOSCA Italian randomised trial enrolled colon cancer patients for 3 or 6 months of either FOLFOX-4 or XELOX adjuvant chemotherapy. In an ancillary pharmacogenetic study, 10 DPYD variants (*2A rs3918290 G>A, *13 rs55886062 T>G, rs67376798 A>T, *4 rs1801158 G>A, *5 rs1801159 A>G, *6 rs1801160 G>A, *9A rs1801265 T>C, rs2297595 A>G, rs17376848 T>C, and rs75017182 C>G), were retrospectively tested for associations with ⩾grade 3 fluoropyrimidine-related adverse events (FAEs). An association analysis and a time-to-toxicity (TTT) analysis were planned. To adjust for multiple testing, the Benjamini and Hochberg's False Discovery Rate (FDR) procedure was used. RESULTS: FAEs occurred in 194 out of 508 assessable patients (38.2%). In the association analysis, FAEs occurred more frequently in *6 rs1801160 A allele carriers (FDR=0.0083). At multivariate TTT analysis, significant associations were found for *6 rs1801160 A allele carriers (FDR<0.0001), *2A rs3918290 A allele carriers (FDR<0.0001), and rs2297595 GG genotype carriers (FDR=0.0014). Neutropenia was the most common FAEs (28.5%). *6 rs1801160 (FDR<0.0001), and *2A rs3918290 (FDR=0.0004) variant alleles were significantly associated with time to neutropenia. CONCLUSIONS: This study adds evidence on the role of DPYD pharmacogenetics for safety of patients undergoing fluoropyrimidine-based chemotherapy.

Se realizó un estudio descriptivo desde Octubre a Diciembre de 2008 en la Emergencia del Hospital Vilardebó estableciéndose la prevalencia del consumo de sustancias psicoactivas en los pacientes que ingresaban por Trastornos Psicóticos. La presencia de consumo reciente se estableció por autorreporte y test en orina para marihuana y cocaína/ pasta base de cocaína. La prevalencia del consumo reciente en los pacientes con Trastornos Psicóticos fue de 17,9 por ciento. Los pacientes con testeado positivo mostraron una tasa total de ingresos mayor que aquella del grupo de los no consumidores, y los ingresos en el último año fueron claramente mayores para el grupo que consume cocaína y sus derivados.
A descriptive study was conducted from October to December 2008 in the emergency room of Hospital Vilardebó (State Mental Facility) to establish the prevalence of psychoactive substance use in patients admitted for Psychotic Disorders. The presence of recent use of substance was established by self-report and urine test for marijuana and cocaine / cocaine base. The prevalence of recent use in patients with psychotic disorders was 17.9 percent. Patients who tested positive showed a total hospitalization rate greater than that of the group of nonusers, and hospitalization in the last year were clearly higher for the group who uses cocaine and its derivatives.

Recent experimental observations, showing the potential role of prolactin (PRL) as a tumor growth factor for prostate cancer and the unfavourable prognostic significance of enhanced chromogranin-A-secreting neuroendocrine cell proliferation, could contribute to a better understanding of the mechanisms responsible for the occurrence of hormone-resistance in the prostate cancer. Moreover, it has been shown that tamoxifen, which consistently exerts estrogenic activity in males, may inhibit prostate cancer cell proliferation in experimental studies. At present, there are no clinical data in humans. This preliminary phase II study was planned in an attempt to evaluate the therapeutic efficacy of tamoxifen in hormone-refractory metastatic prostate cancer. The study included 14 consecutive metastatic prostate cancer patients, who had progressed under the classical endocrine therapy with LHRH-analogs and/or anti-androgens. Patients received the same treatment plus tamoxifen at 20 mg/day orally. A decline greater than 50% in prostate-specific antigen (PSA) levels occurred in 4/14 (29%) patients within the first 2 months of therapy, with a median duration of 5 months. Mean pre-treatment levels of PRL were significantly higher in responder patients than in those who progressed. Moreover, abnormally high pre-treatment levels of PRL were found in 5/14 (36%) patients. The percent of clinical responses observed in patients with pre-treatment hyperprolactinemia was significantly higher than that found in patients with normal pre-treatment PRL concentrations. Finally, a significant decline in mean PRL levels upon tamoxifen therapy occurred only in the responder patients. This preliminary study seems to justify further clinical research to confirm the potential efficacy of tamoxifen in the treatment of hormone-refractory prostate cancer and to identify possible parameters, which may predict the response to treatment.

The hormone resistance of prostate cancer has been proved to depend at least in part on enhanced neuroendocrine activity and the resultant increase in blood concentrations of chromogranin A. Other experimental observations have suggested the involvement of prolactin (PRL), which appears to be a potential growth factor for prostate cancer. Abnormally high levels of PRL have been detected in metastatic prostate cancer, but the clinical significance of this finding has still to be clarified. In an attempt to explain the prognostic significance of serum PRL levels in prostate cancer, in this preliminary study we have analyzed the PRL levels in a group of metastatic prostate cancer patients with hormone-dependent or hormone-resistant cancer. The study included 50 patients with metastatic prostate cancer, 15 of whom had hormone-resistant tumors. The serum levels of PRL were measured by the RIA method. Abnormally high concentrations of PRL were found in 11/50 (22%) patients. Moreover, the percent of patients with cancer-related hyperprolactinemia was significantly higher in the hormone-resistant group than in the hormone-dependent group (8/15 vs 3/35, p < 0.01). This study confirms the possible existence of a hyperprolactinemic state in metastatic prostate cancer, as previously reported by other authors. Moreover, it appears to demonstrate that the occurrence of hyperprolactinemia is more frequent in hormone-resistant neoplasms, suggesting the possible involvement of PRL in hormone independence. Further studies concomitantly evaluating PRL and chromogranin A blood concentrations will be necessary to establish whether the hyperprolactinemia precedes and promotes the onset of hormone resistance in prostate cancer, or whether it is simply a consequence of the hormone independence.

It has been shown that each manipulation of the mammary region, including breast surgery, may stimulate prolactin secretion. However, it has also been observed that in more than 50% of breast cancer patients surgical removal of the tumor is not followed by enhanced prolactin secretion. This might be indicative of an altered psychoneuroendocrine control of the mammary gland, which could lead to the onset of more biologically aggressive breast cancer. In fact, surgery-induced hyperprolactinemia has been proven to be associated with a better prognosis in terms of survival in node-negative breast cancer patients. The present study was performed to investigate the impact of postoperative hyperprolactinemia on the disease-free survival (DFS) of breast cancer patients with axillary node involvement. The study included 100 consecutive node-positive breast cancer patients who were followed for at least 10 years. Surgery-induced hyperprolactinemia occurred in 45/100 (45%) patients without any significant correlation with the main prognostic variables including number of involved nodes and ER status. The two groups of patients received the same adjuvant therapies. After a median follow-up of 151 months, the recurrence rate in patients with surgery-induced hyperprolactinemia was significantly lower than in patients with no postoperative hyperprolactinemia (23/45 vs 43/55, p<0.01). Moreover, DFS was significantly longer in hyperprolactinemic patients than in patients who had no enhanced secretion of prolactin postoperatively. In agreement with the results described previously in node-negative breast cancer, our study demonstrates the favorable prognostic significance of surgery-induced hyperprolactinemia in terms of DFS duration also in breast cancer patients with axillary node involvement, independent of the other well-known prognostic variables, thereby confirming that the psychoneuroendocrine status of cancer patients may influence the prognosis of their disease.

RESUMEN
OBJECTIVE: Single-agent epirubicin was tested as primary chemotherapy treatment in patients with early breast cancer >3 cm. METHODS: 100 women with locally advanced breast cancer >3 cm were treated with three cycles of single-agent epirubicin at a dose of 120 mg/m2. All patients showing tumor shrinkage to less than 3 cm were considered candidates for conservative surgery (quadrantectomy); in the remaining patients modified radical mastectomy was carried out. Postsurgical treatment consisted of CMF chemotherapy except for postmenopausal node-positive, estrogen-positive patients who were assigned to hormonal treatment with tamoxifen and postmenopausal node-negative, estrogen-positive ones who did not receive any treatment. RESULTS: Quadrantectomy was carried out in 71 patients. At the median follow-up time of 69 months, the relapse rate was 29.6% among patients who underwent quadrantectomy (21 out of 71) and 58.6% among patients who underwent modified radical mastectomy (17 out of 29). CONCLUSIONS: Single-agent chemotherapy with anthracyclines could appear to be an effective treatment in inducing a tumor downstaging in patients with early breast cancer >3 cm. This treatment can be administered outside clinical trials in patients who desire to preserve their body integrity. Further prospective, randomized trials are needed in order to validate and better define the role of epirubicin in the neoadjuvant strategy of breast cancer patients.

Building upon the concept of schedule-specific biochemical modulation of 5-fluorouracil (FU), which alternates bolus and continuous infusion (CI) FU, we have incorporated oxaliplatin (l-OHP) following the bolus part of the regimen to explore the activity of this new combination. Patients with advanced, untreated, measurable colorectal cancer received sequential methotrexate (MTX) (days 1 and 15)-->l-OHP+FU (days 2 and 16) (200, 85 and 600 mg m(-2), respectively) followed by 3 weeks of CI FU (200 mg m(-2) day(-1)) given from day 29 to 50, modulated by weekly leucovorin (LV) (20 mg m(-2)). After 1 week of rest, the second cycle was started. The treatment was continued until progression or patient's refusal. According to the intention-to-treat analysis on all 46 patients accrued, the response rate was 42% (95% CL=28-55%), with three complete responses and 16 partial responses. The median overall survival was 15.9 months and the median progression-free survival 6.9 months. Toxicity was very mild, with the bolus part of the regimen more toxic than the infusional part (24 vs 7% of grade III-IV, respectively). This new combination of MTX -->l-OHP-FU followed by FU CI is well tolerated, feasible and produces activity results similar to other more simple, but more toxic, regimens. Pros and cons of the different fluoropyrimidines-l-OHP combinations are discussed.

The evidence of lymphocytopenia has been demonstrated to predict a poor prognosis in terms of survival in advanced cancer patients. This finding is not surprising because of the fundamental role of lymphocytes in mediating tumor cell destruction. Despite the importance of lymphocytes in the pathogenesis of cancer, there are only few data about the profile and the function of lymphocytes during the various antitumor therapies, and in particular the relation between lymphocyte pretreatment number and response to chemotherapy remains to be established. The present study was performed to evaluate whether the evidence of lymphocytopenia before the onset of treatment may influence the efficacy of chemotherapy in metastatic cancer patients affected by the most frequent tumor types. The study included 183 patients (lung cancer: 89; colorectal cancer: 63; breast cancer: 31), 95 of whom had been previously treated with chemotherapy. The chemotherapeutic regimens consisted of oxaliplatin plus 5-fluorouracil and folates in untreated colorectal cancer, weekly irinotecan in pretreated colorectal cancer, cisplatin plus gemcitabine or etoposide in untreated lung cancer, weekly vinorelbine in pretreated lung cancer, and taxotere in breast cancer patients who had been previously treated with anthracyclines. Lymphocyte count was considered to be abnormally low for values below 1500/mm3. Lymphocytopenia was found in 79/183 (43%) patients, without any significant differences in relation to tumor histology. A complete response (CR) was achieved in 6/104 patients with a normal lymphocyte count and in none of the 79 lymphocytopenic patients. A partial response (PR) was obtained in 39 patients with a normal lymphocyte count and in only eight patients with a low lymphocyte count prior to therapy. Therefore, irrespective of the type of chemotherapy, the objective tumor response rate (CR + PR) in lymphocytopenic patients was significantly lower than in patients with normal pretreatment lymphocyte counts (8/79 vs 45/104; p < 0.001). This study shows that the evidence of lymphocytopenia prior to chemotherapy is associated with a lower efficacy of treatment in terms of objective tumor regression rates in patients with metastatic solid tumors, and suggests that the action of chemotherapy may depend at least in part on an interaction with the antitumor immunity. Pretreatment lymphocyte count may represent a new, simple biological marker to be taken into consideration by oncologists in the chemotherapeutic treatment of metastatic cancer.

Pain is a highly distressing symptom for patients with advanced cancer. WHO analgesic ladder is widely accepted as a guideline for its treatment. Our aim was to describe pain prevalence among patients diagnosed with advanced non-small-cell lung cancer (NSCLC), impact of pain on quality of life (QoL) and adequacy of pain management. Data of 1021 Italian patients enrolled in three randomised trials of chemotherapy for NSCLC were pooled. QoL was assessed by EORTC QLQ-C30 and LC-13. Analgesic consumption during the 3 weeks following QoL assessment was recorded. Adequacy of pain management was evaluated by the Pain Management Index (PMI). Some pain was reported by 74% of patients (42% mild, 24% moderate and 7% severe); 50% stated pain was affecting daily activities (30% a little, 16% quite a bit, 3% very much). Bone metastases strongly affected presence of pain. Mean global QoL linearly decreased from 64.9 to 36.4 from patients without pain to those with severe pain (P<0.001). According to PMI, 616 out of 752 patients reporting pain (82%) received inadequate analgesic treatment. Bone metastases were associated with improved adequacy and worst pain with reduced adequacy at multivariate analysis. In conclusion, pain is common in patients with advanced NSCLC, significantly affects QoL, and is frequently undertreated. We recommend that: (i). pain self-assessment should be part of oncological clinical practice; (ii). pain control should be a primary goal in clinical practice and in clinical trials; (iii). physicians should receive more training in pain management; (iv). analgesic treatment deserves greater attention in protocols of anticancer treatment.

In view of its potential action as a growth factor, the evidence of abnormally high blood levels of prolactin (PRL) is associated with a poor prognosis in metastatic breast cancer. Moreover, metastatic breast cancer-related hyperprolactinemia has proven to counteract the efficacy of cancer chemotherapy. The negative influence of high blood levels of PRL on the efficacy of chemotherapy in metastatic breast cancer has been confirmed by previous preliminary studies, showing that the concomitant administration of the anti-prolactinemic dopaminergic agent bromocriptine may enhance the therapeutic effect of chemotherapy. However, the clinical use of bromocriptine is limited by its short duration and gastrointestinal toxicity. Therefore, new anti-prolactinemic drugs, characterized by less toxicity and a longer duration of activity, such as Cabergoline (CBG), could be more appropriated to control PRL secretion in breast cancer. On this basis, a study was planned to evaluate the efficacy and tolerability of a concomitant administration of CBG with weekly low-dose Taxotere (TXT) in pretreated metastatic breast cancer under chemotherapy. The study group comprised 70 metastatic breast cancer patients (females), pretreated with at least one previous chemotherapeutic line containing anthracyclines, who were randomized to be treated with TXT alone or TXT plus CBG. TXT 25 mg/m2 was given i.v. at weekly intervals for at least 9 consecutive cycles. CBG was given orally at 0.5 mg once per week. Abnormally high pre-treatment levels of PRL were seen in 24/70 (34%) patients, 11 of whom were treated with TXT plus CBG, whereas the other 13 received TXT alone. CBG induced a complete normalization of the PRL levels in all patients within the first two weeks of therapy, whereas no normalization of PRL occurred spontaneously in patients treated with chemotherapy alone. The objective tumor regression rate was significantly higher in patients concomitantly treated with CBG than in those who received chemotherapy alone (31/34 vs 13/36, p < 0.05), and this difference was particularly evident in patients with high PRL levels prior to therapy (6/11 vs 2/13). No CBG-related toxicity occurred. On the contrary, chemotherapy-induced asthenia was significantly lower in patients concomitantly treated with CBG (5/34 vs 11/36, p < 0.05). This study shows that the chemoneuroendocrine therapy of weekly low-dose TXT plus the anti-prolactinemic drug CBG is a new, effective and well-tolerated therapy for metastatic breast cancer. It may also be recommended in heavily pretreated patients or in those with poor clinical status.

The present study describes supportive care (SC) in patients with advanced non-small-cell lung cancer (NSCLC), evaluating whether it is affected by concomitant chemotherapy, patient's performance status (PS) and age. Data of patients enrolled in three randomised trials of first-line chemotherapy, conducted between 1996 and 2001, were pooled. The analysis was limited to the first three cycles of treatment. Supportive care data were available for 1185 out of 1312 (90%) enrolled patients. Gastrointestinal drugs (45.7%), corticosteroids (33.4%) and analgesics (23.8%) were the most frequently observed categories. The mean number of drugs per patient was 2.43; 538 patients (45.4%) assumed three or more supportive drugs. Vinorelbine does not produce substantial variations in the SC pattern, while cisplatin-based treatment requires an overall higher number of supportive drugs, with higher use of antiemetics (41 vs 27%) and antianaemics (10 vs 4%). Patients with worse PS are more exposed to corticosteroids (42 vs 30%). Elderly patients require drugs against concomitant diseases significantly more than adults (20 vs 7%) and are less frequently exposed to antiemetics (12 vs 27%). In conclusion, polypharmacotherapy is a relevant issue in patients with advanced NSCLC. Chemotherapy does not remarkably affect the pattern of SC, except for some drugs against side effects. Elderly patients assume more drugs for concomitant diseases and receive less antiemetics than adults.

BACKGROUND: This phase II study was initiated to determine the activity and toxicity of a combination of gemcitabine (GEM) and cisplatin (CDDP) in patients with pancreatic cancer. PATIENTS AND METHODS: CDDP 35 mg/m(2) was given as a 30-min infusion and GEM 1000 mg/m(2) as a 30-min infusion. Both drugs were administered once weekly for 2 consecutive weeks out of every 3 weeks to chemonaive patients with locally advanced or metastatic pancreatic cancer. RESULTS: Forty-five advanced pancreatic cancer patients received this regimen for a total of 180 cycles of chemotherapy. One complete and four partial responses have been observed for an overall response rate of 9% (95% confidence interval 10% to 11%). Twenty-one patients (46%) had stable disease and 19 progressed on therapy. The median time to progression was 3.6 months, with a median survival of 5.6 months. A clinical benefit was obtained in nine of 37 patients (24%). Side-effects were mainly represented by hematological toxicity. Grade 3/4 WHO toxicities included neutropenia (6% of the patients) and thrombocytopenia (11%). The dose of GEM and CDDP was reduced in 14 patients (31%) and treatment was delayed in 10 patients (22%). CONCLUSIONS: Our results in terms of response rate, clinical benefit and survival do not support an advantage for the combination of GEM and CDDP given by this schedule.

PURPOSE: To evaluate whether two commonly used newer platinum-based regimens offer any advantage over vinorelbine-cisplatin (reference regimen) in response rate for patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Chemotherapy-naive patients were randomized to receive gemcitabine 1,250 mg/m(2) days 1 and 8 plus cisplatin 75 mg/m(2) day 2 every 21 days (GC arm), or paclitaxel 225 mg/m(2) (3-hour infusion) then carboplatin (area under the concentration-time curve of 6 mg/mL x min), both on day 1 every 21 days (PCb arm), or vinorelbine 25 mg/m(2)/wk for 12 weeks then every other week plus cisplatin 100 mg/m(2) day 1 every 28 days (VC arm). RESULTS: Six hundred twelve patients were randomized to treatment (205 GC, 204 PCb, and 203 VC). Overall response rates for the GC (30%) and PCb (32%) arms were not significantly different from that of the VC arm (30%). There were no differences in overall survival, time to disease progression, or time to treatment failure. Median survival for the GC, PCb, and VC groups was 9.8, 9.9, and 9.5 months, respectively. Neutropenia was significantly higher on the VC arm (GC 17% or PCb 35% v VC 43% of cycles, P <.001), as was thrombocytopenia on the GC arm (GC 16% v VC 0.1% of cycles, P <.001). Alopecia and peripheral neurotoxicity were most common on the PCb arm, as was nausea/vomiting on the VC arm (P <.05). CONCLUSION: Efficacy end points were not significantly different between experimental and reference arms, although toxicities showed differences. These findings suggest that chemotherapy in NSCLC has reached a therapeutic plateau.

Recently, we reported a highly active regimen in advanced gastric cancer including a weekly administration of cisplatin, epidoxorubicin, leucovorin, 5-fluorouracil with the support of filgrastim. In order to simplify the administration and to decrease the toxicity of these drugs, mainly epidoxorubicin-induced alopecia, we designed a regimen including an infusional 5-fluorouracil schedule according to the de Gramont regimen, cisplatin and mitomycin C replacing epidoxorubicin. Forty-five patients with advanced or metastatic gastric cancer were treated with cisplatin 50 mg m(-2) i.v. on day 1, every 2 weeks, 6S-stereoisomer-leucovorin 100 mg m(-2) i.v. followed by 5-fluorouracil 400 mg m(-2) i.v. bolus and 600 mg m(-2) i.v. in a 22-h infusion, on days 1 and 2, every 2 weeks, and mitomycin C 7 mg m(-2) i.v. bolus on day 2, every 6 weeks. Grades 3-4 toxicities (National Cancer Institute-Common Toxicity Criteria) consisted mainly of neutropenia and thrombocytopenia. Five patients had a complete response and 16 had a partial response for an overall response rate of 46.7% (95% confidence interval, 32.1-61.2%). The median survival was 11 months. The combination of cisplatin, 5-fluorouracil and leucovorin according to de Gramont, and mitomycin C seems to be an active and safe regimen in the treatment of advanced gastric cancer. Because of its low cost it may be suggested for patients not enrolled into clinical trials.

In advanced gastric cancer, we investigated feasibility and activity of sequential chemotherapy with docetaxel after an intensive weekly regimen consisting of cisplatin, epidoxorubicin, fluorouracil, leucovorin (PELF) plus filgrastim. Chemotherapy-naive patients with relapsed or metastatic gastric cancer received 8 weekly administrations of chemotherapy with cisplatin 40 mg/m(2), fluorouracil 500 mg/m(2), epidoxorubicin 35 mg/m(2), 6S-stereoisomer of leucovorin 250 mg/m(2) and glutathione 1.5 g/m(2). On the other days filgrastim 5 microg kg(-1) was administered by subcutaneous injection. Subsequently, patients with partial response or stable disease received 3 cycles of docetaxel 100 mg/m(2) every 3 weeks. 40 patients have been enrolled and they are evaluable for response and toxicity. After the PELF regimen, 3 patients achieved complete response, 13 patients showed partial response, 21 patients had stable disease and 3 patients progressed (40% response rate; 95% CI 25% to 55%). After docetaxel, 9 out 34 patients improved the outcome (26.5%); 7 patients with stable disease achieved partial response and 2 patients with partial response achieved complete response. The overall response rate in the 40 patients was 57.5% (95% CI, 42.5% to 72.5%). The PELF regimen did not cause any grade IV toxicity, the most frequent grade III acute side-effects were thrombocytopenia and vomiting which occurred in the 10% of 320 PELF cycles. Docetaxel caused grade III-IV neutropenia and thrombocytopenia in the 10% and the 19% of cycles respectively. Fatigue was a frequent side-effect during both PELF and docetaxel chemotherapy. The sequential application of docetaxel after PELF chemotherapy gained major objective responses with manageable toxicity. This strategy is worth of further investigation in the setting of palliative or neoadjuvant chemotherapy.

BACKGROUND: Following the demonstration that vinorelbine improves survival and quality of life compared with best supportive care in elderly patients with advanced non-small-cell lung cancer (NSCLC), we started the three-arm prospective Multicenter Italian Lung Cancer in the Elderly Study (MILES) trial of vinorelbine, gemcitabine and gemcitabine + vinorelbine. DESIGN: Within the randomized phase 3 trial, pilot single-stage phase 2 studies were planned for gemcitabine and for gemcitabine + vinorelbine. Eligible patients are aged 70 or more, with stage IV or IIIb (with metastatic supraclavear nodes or malignant pleural effusion) NSCLC. Single-agent gemcitabine is given at 1200 mg/m(2) on days 1 and 8; in the combination, gemcitabine is given at 1000 mg/m(2) and vinorelbine at 25 mg/m(2), both on days 1 and 8, every 3 weeks. RESULTS: As planned 49 patients were enrolled in each group. Median age was 74 in both groups. Two-thirds of patients had stage IV disease. The response rate was 18.4% (95% exact CI 8.8-32.0) with both treatments. With single-agent gemcitabine main toxicities were grade 4 thrombocytopenia and grade 2 hepatic toxicity, in one patient each, and grade 2 pulmonary toxicity in two patients. With gemcitabine + vinorelbine combination there were grade 4 neutropenia and thrombocytopenia (one patient each), grade 3 anemia requiring red blood cell transfusion (two patients), and grade 4 fever in two patients. Four patients, with severe cardiac comorbidities, suffered grade 3 heart toxicity with atrial flutter or fibrillation, followed by congestive heart failure responsive to treatment. CONCLUSION: Both single-agent gemcitabine and the gemcitabine + vinorelbine combination are sufficiently active and tolerable to allow continuation of the MILES study.

A multicentre phase 2 trial (single-stage design) was undertaken to test the efficacy and toxicity of carboplatin (AUC 6 according to Calvert) plus paclitaxel (175 mg/m(2)3-h infusion) every 4 weeks in the first line treatment of patients affected by extensive small cell lung cancer. The primary end-point of the trial was the objective response rate. 31 objective responses among 50 patients were considered necessary to proceed to a phase 3 trial. 48 patients were enrolled (median age 59 years). Treatment was very well tolerated. 3 patients (6.2%) had a complete response and 23 (47.9%) a partial response, for an overall response rate of 54.2% (95% CI: 39.2-68.6). Median time to progression was 5.7 months (95% CI: 5.2-6.2). Median survival was 9.6 months (95% CI: 7.2-14.6), with a median follow-up time of alive patients of 12 months. At 1 year, the probability of being progression-free or alive was 0.16 and 0.43, respectively. In conclusion, carboplatin plus paclitaxel as given in the present study is very well tolerated but not sufficiently active to warrant phase 3 comparison with standard chemotherapy regimens.
