There is the urgent need to study the effects of immunomodulating agents as therapy for Covid-19. An observational, cohort, prospective study with 30 days of observation was carried out to assess clinical outcomes in 88 patients hospitalized for Covid-19 pneumonia and treated with canakinumab (300 mg sc). Median time from diagnosis of Covid-19 by viral swab to administration of canakinumab was 7.5 days (range 0–30, IQR 4–11). Median PaO2/FiO2 increased from 160 (range 53–409, IQR 122–210) at baseline to 237 (range 72–533, IQR 158–331) at day 7 after treatment with canakinumab (p 9/L, respectively, p p

Numerous geriatric patients develop colorectal disease. Elderly patients are often considered high-risk surgical candidates. Enhanced recovery after surgery (E.R.A.S.) has been proven to be beneficial for patients. The aim of the study was to evaluate the results of an ERAS protocol in older patients that underwent colorectal surgery compared to younger patients.In the period between January 2010 to December 2015 a total of 589 patients underwent elective colorectal surgical interventions treated within the E.R.A.S pathway: 211 patients younger than 65 years, 175 patients aged from 66 years to 75 years, and 203 patients older than 75 years. End point of interest were postoperative complications, 90-day mortality, length of hospital stay and readmission within 30 days.Significant differences between the three groups were observed for comorbidities (p:0.001); in particular older patients had significantly more diabetes, renal, cardiac, and respiratory diseases, ASA (p 0.001), presence of malignancy (p 0.001). However there were not differences between the groups in surgical procedures (p = 0.095), operative time (p = 0.823), anastomotic leakage (p = 0.960), hospital stay (p = 0.081), readmission rate (p = 0.904), 90-days mortality (p = 0.183) and morbidity (p = 0.973) in accordance with Clavien-Dindo classification. Multivariate logistic regression analysis showed that advanced age in E.R.A.S. pathway is not a predictive factor of morbidity, readmission within 30 days and 90-day mortality.There was no significant difference in morbidity, 90-day mortality, length of stay or readmission rate in patients aged over 75 years compared with younger patients. Old age does not represent a contraindication to the implementation of the E.R.A.S protocol in patients that underwent colorectal surgery. WHAT DOES THIS PAPER ADD TO THE EXISTING LITERATURE?: In the literature there are not many studies that address the impact of older age in the treatment of colorectal disease in an ERAS program. The aging of the population raises new questions in the management of the colorectal surgery in the elderly. ERAS pathway has been proven to be beneficial for patients, which results in a reduction of postoperative morbidity. Compared to what is reported in the literature this study confirms that ERAS program in colorectal surgery can be applied in older patients with no significant difference in morbidity, 90-day mortality, length of stay or readmission rate compared with younger.

The incidence of second non-breast primary cancer following adjuvant treatment was evaluated using data from patients enrolled from 1978 to 1999 in four International Breast Cancer Study Group (IBCSG) trials. The occurrence of these tumours as sites of the first failure was assessed separately for two treatment comparisons: toremifene versus tamoxifen for 5 years in 1035 patients in IBCSG Trials 12-93 and 14-93 with a median follow-up of 8 years and endocrine therapy (toremifene or tamoxifen) versus chemo-endocrine therapy (CMF or AC plus toremifene or tamoxifen) in 1731 patients from IBCSG Trials III, VII and 12-93, with a combined median follow-up of 14 years. No significant differences in second non-breast primary tumours were observed in either comparison. In particular, the incidences of second primary uterine tumours with toremifene and tamoxifen were similar and no significant increase of secondary leukaemias was observed with chemo-endocrine therapy compared with endocrine therapy.

Background Sublingual immunotherapy (SLIT) proved effective and safe in respiratory allergy, and thus its use in hymenoptera allergy can be hypothesized. Objective We sought to assess, in a proof-of-concept study, whether SLIT might potentially be beneficial in hymenoptera allergy. The sting challenge in large local reactions (LLRs) was used to test this hypothesis. Methods We performed a randomized, double-blind, placebo-controlled study involving patients with LLRs who were monosensitized to honeybee. After the baseline sting challenge, they were randomized to either SLIT or placebo for 6 months. The treatment (Anallergo, Florence, Italy) involved a 6-week build-up period, followed by maintenance with 525 μg of venom monthly. The sting challenge was repeated after 6 months. Results Thirty patients (18 male patients; mean age, 44.5 years) were enrolled, and 26 completed the study, with 1 dropout in the active group and 3 dropouts in the placebo group. In the active group the median of the peak maximal diameter of the LLRs decreased from 20.5 to 8.5 cm ( P = .014), whereas no change was seen in the placebo group (23.0 vs 20.5 cm, P = not significant). The diameter was reduced more than 50% in 57% of patients. One case of generalized urticaria occurred in a placebo-treated patient at sting challenge. No adverse event caused by SLIT was reported. Conclusion Honeybee SLIT significantly reduced the extent of LLRs, and its safety profile was good. Although LLRs are not an indication for immunotherapy, this proof-of-concept study suggests that SLIT in hymenoptera allergy deserves further investigation. Trials involving systemic reactions and dose-ranging studies are needed.

Background Cisplatin-containing regimens represent the gold standard in the treatment of advanced non-small cell lung cancer, but carboplatin is often preferred for its better toxic profile when palliation is the aim of the treatment. The synergistic effect and tolerability of carboplatin-gemcitabine combination are well known. In this phase II trial, we evaluated the activity and safety of a schedule with carboplatin and gemcitabine, defined in our previous phase I trial. Methods Thirty-seven patients with measurable stage IV non-small cell lung cancer were treated with carboplatin, AUC 4.5 mg/ml/min on day 1, and gemcitabine, 800 mg/m2 on days 1 and 8, every 21 days. All patients were treated until disease progression or intractable toxicity and were evaluated before each course of chemotherapy for toxicity and after every 3 courses for response. Results After a median follow-up of over 10 months, complete response, partial response, and stabilization of the disease were observed in 3 (8.1%), 9 (24.3%), and 15 patients (40.5%), respectively. Median time to progression was 7 months. At this writing, 27 patients have died, with a median survival of 10 months, and 29 (78.3%), 16 (43.2%), and 11 (29.7%) patients are alive after 6, 12, and 15 months of follow-up, respectively. Toxicity was mild, and mainly hematological, with a significant correlation with the number of courses of chemotherapy (P = 0.0003). Conclusions Our results are comparable with those reported in the literature and confirm the good activity and tolerability of the carboplatin-gemcitabine combination. Up to 4 courses of chemotherapy with carboplatin and gemcitabine may represent an interesting option in the palliative treatment of non-small cell lung cancer.

We report three patients with advanced "hormone-resistant" prostate cancer, each of whom had rapid progression of the disease during treatment with megestrol acetate for cancer cachexia. All patients had been previously treated with total androgenic deprivation. With progression of the disease, megestrol acetate was given to palliate the cancer-related wasting syndrome. No other antineoplastic drugs were contemporaneously given, and no concomitant condition that could favor the progression of the disease was present. The worsening observed while receiving megestrol acetate, and the atypical withdrawal syndrome occurring after the treatment was stopped, seem to suggest a promoting role of megestrol acetate in advanced "hormone-resistant" prostate cancer. The risk of rapid disease progression overwhelming the anti-cachectic palliative effect should be kept in mind when progestins are administered as a palliative treatment of cancer cachexia in patients with advanced "hormone-resistant" prostate cancer.

Background The purpose of this study was to evaluate our results involving femorocrural bypasses by comparing heparin-bonded expanded polytetrafluoroethylene (HePTFE) graft (Propaten) modified with handmade distal compliant HePTFE cuffs (mHePTFE graft) to great saphenous vein (GSV) graft. Methods A retrospective study involving 74 femorocrural bypasses performed from January 2010 to May 2013 at a single institution was carried out. The indication for revascularization was critical limb ischemia (Rutherford stages 4–6. Forty-one femorocrural bypasses were created in 37 patients with unavailable GSVs using modified ringed HePTFE grafts with a handmade distal radial stretch HePTFE cuff to reduce the mismatch compliance between the graft and the artery wall. Thirty-three femorocrural bypasses were created using a reversed GSV graft. The results were analyzed in terms of primary graft patency, limb salvage, and patient survival using univariate (Kaplan–Meier curves and log-rank test) and multivariate (Cox regression) analyses. Results The 2 groups were statistically comparable for main risk factors, Rutherford stage, and target artery for distal anastomoses. The run-off anatomy did not significantly differ between the prosthetic and the vein bypass group. The cumulative 30-day operative mortality rate was 2.9%. At 1, 2, and 3 years, the 2 groups were equivalent in primary graft patency (the mHePTFE group: 84%, 80%, and 70%, respectively; the GSV group: 84%,71%, and 71%, respectively; P = 0.93) and were also equivalent in terms of limb salvage (the mHePTFE group: 87%, 87%, and 76%, respectively; the GSV group: 84%, 75%, and 75%, respectively; P = 0.78) and patient survival (the mHePTFE group: 87%, 75%, and 75%, respectively; the GSV group: 87%, 73%, and 65%, respectively; P = 0.86). At Cox regression analysis, only postoperative treatment with warfarin therapy compared with double antiplatelet therapy was independently associated with poorer primary patency (P = 0.003; 95% confidence interval, 1.80–18.00; hazard ratio, 5.7). Conclusions In this retrospective study regarding femorocrural bypasses, the mHePTFE grafts had 1-, 2-, and 3-year primary patency and limb salvage results which were not significantly different from those in the GSV grafts. Additional randomized data and larger studies are needed to confirm these results.

Background. Staging procedures used to detect metastatic breast cancer at the time of diagnosis are bone scan (BS), chest X-ray (CXR), liver ultrasonography (LUS) and laboratory parameters (LP). These procedures are expensive and not all patients need them. We aimed to identify groups of patients with different risks for metastatic disease. Methods. We reviewed data from 1,218 consecutive cases of breast cancer. Pathological and biological param-eters and instrumental procedures performed at the time of diagnosis and during 6 months of follow-up were recorded. True positive and negative, false positive and negative cases were evaluated. All cases were grouped on the basis of tumour size, nodal involvement, biological characteristics, menopausal status and age. Results. We observed 46 (3.8%) true positive cases with metastatic disease at the time of diagnosis. Documenta-tion relating to BS, CXR and LUS was available for 1,193, 1,206 and 1,206 patients, respectively, with 37 (3.1%), 8 (0.7%) and 10 (0.8%) true positive tests. Logistic regression analysis showed significant odds ratio estimates for pT status and nodal status, thus highlighting the role of these morphological data. These findings suggest that breast cancer patients can be divided into two subgroups: first group pT1-3N0-1, with ≤3 involved nodes, and second group pT1-3N1 with ≥4 involved nodes, pT4 and pN2 (metastases detection rate 1.46 and 10.68%, respectively). In the former group the appropriate procedures of staging would only be laboratory parameters, whereas in the latter group BS, CXR, LUS, LP and tumour markers CEA and CA15.3 would be necessary. Conclusions. The standard staging procedures to detect metastatic disease at breast cancer diagnosis require modification. On the basis of the literature data and our findings, the full staging procedure is appropriate in the second group of patients.

Background Although Indocyanine green (ICG) is used to find sentinel nodes (SN) in patients with breast cancer (BC), its role in clinical practice is still debated, and needs a definitive validation to be included in the standard approach to finding sentinel nodes in breast cancer. Materials and methods To validate the ICG methods of detecting the SN in BC we have recently concluded a prospective validation trial. Patients with clinically node-negative, invasive early BC scheduled for breast surgery and SN biopsy were included in the trial. All the patients underwent SN detection using both the standard-of-care procedure using radioisotope technetium (99mTc) and the ICG, using the Photodynamic Eye camera. A comparison of the detection rate and the diagnostic accuracy of the two methods was performed to detect the equivalency of the two approaches. Results At the end of the enrolment, 301 patients were considered eligible and included in the trial, and 589 nodes were removed. Five hundred and eighty-three nodes (99%) were identified with ICG (median 2 nodes per patient) and 452 (76.7%) were identified with 99mTc (median 2 nodes per patient). A concordance index of 98.75% (CI, 95% = 97.1%–99.5%) was detected. The dosage given ranged from 0.3 to 1.4 ml. ICG was used in all patients eligible for SN biopsy without any significant acute side effects. Conclusions The index of concordance between 99mTc and ICG seems to be extremely high, suggesting that ICG could be validated as an alternative method to 99mTc in the detection of SN in BC.

Nineteen patients with recurrent or refractory ovarian carcinoma after a first-line platinum-based chemotherapy were treated with a 3-hour i.v. infusion of paclitaxel 175 mg/m2 every 3 weeks from November 1992 to October 1996. The major hematologic toxicity was neutropenia (63.2%). No febrile neutropenia was observed. Other hematologic effects were leukopenia (47.4%) and anemia (47.4%). The main non-hematologic toxicities were as follows: neuropathy (52.6%), nausea and vomiting (36.8%), myalgia (36.8%), cardiac toxicity (15.8%) and mucositis (10.5%). Alopecia was observed in the majority of cases. The overall response rate was 47.4%, with 5 (26.3%) complete responses (CRs) and 4 (21.1%) partial responses (PRs). The median duration of response was 7 months (range: 3-19), with a median follow-up of 17 months (range: 3-61). Quality of life of responding patients was good. Our results confirm that paclitaxel as second-line therapy in relapsed and refractory ovarian cancer patients is an acceptable treatment with a good safety profile, and can be safely administered at the dose of 175 mg/m2. In our study paclitaxel was more active in relapsed than in refractory patients. Consequently, further studies are needed to identify more effective drugs for the refractory subset.

Bone scan (BS), chest X-rays (CXR), liver ultrasonography (LUS) and laboratory parameters (LP) are frequently used as routine staging procedures for breast cancer patients. These procedures are not always appropriate in either clinical or research settings, regardless of the stage. The aim of this study was to identify groups of patients with differing risks for metastases in order to select more precise standard staging procedures.The staging data relating to 406 breast cancer patients consecutively referred to our institution between November 1989 and October 1996 were analysed including pathological TNN grading and biological parameters. All of the cases with a positive or suspicious pre-operatory staging and who proved to have metastatic disease before surgery or during the first six months of follow-up were considered true-positive; all of the other cases with a positive or suspicious initial staging but with no evidence of distant metastasis before surgery and with a disease-free survival longer then six months were considered false-positive. In the same way all cases with negative initial staging who relapsed during the first six months of follow-up were considered false-negative and those with negative initial staging and with a disease-free survival longer then six months were considered true-negative. Statistical analysis was performed using Fisher's exact test.BS, CXR and LUS, 388, 399 and 398 examinations respectively, were considered available, and 17 (4.38%), six (1.5%) and four (1%), respectively, proved to be true-positive. A statistically significant difference was observed when our cases were grouped according to T status (T4 vs. T1-T2-T3, P0.01) and nodal status (N0-N1 cases with less than three involved nodes and N1 with more than three positive lymph nodes N2 patients, P0.01).The present study suggests that breast cancer patients can be divided into three subgroups with different detection rates for distant metastases at staging (0.59%, 2.94% and 15.53%), and that the standard practice should be changed. In the first (T1N0 and T1N1 patients withor = 3 positive lymph nodes--41.13% of the patients) and the second group (T2N0, T2N1 withor = 3 positive lymph nodes, T3N0 and T3N1 patients withor = 3 positive lymph nodes--33.49% of the patients) there is no need for a complete set of staging procedures, whereas full procedural staging is needed in the third group of patients (T4, N1 with3 lymph nodes and N2, 25.37% of the patients).

Several antineoplastic drugs are known to have cardiactoxic effects [1-4] which may be dose-limiting, and whichrange over a wide spectrum of cardiac pathology, in-cluding cardiomyopathy, ischaemia and arrhythmia [1].Supraventricular and ventricular arrhythmias often oc-cur suddenly and unexpectedly, and are sometimes life-threatening. Their pathogenesis is often ascribed todirect drug-induced myocardial toxicity, but indirectmechanisms due to electrolyte imbalances may also beinvolved [1, 2, 4].Cisplatin is widely used in the treatment of many neo-plastic diseases. Its major side effects include nephrotox-icity, myelotoxicity, ototoxicity, neurotoxicity and gastro-intestinal toxicity [5], but changes in intracellular andextracellular magnesium (Mg) concentrations are alsofrequently reported [6-10]. Conversely, cardiac toxicityis only occasionally observed [11-13], and is commonlyconsidered to be a consequence of direct cisplatin-induced myocardial toxicity [11]. In this paper, we reportthree cases of supraventricular tachyarrhythmia, in whichcisplatin-induced changes in Mg homeostasis may havebeen implicated.CaselIn September 1995, a 68-year-old man was admitted toour department for treatment of a stage HI B non-small-cell lung cancer (NSCLC), without evidence of pericar-dial involvement on computed tomography (CT). Hehad no history of cardiac disease, and his arterial bloodpressure, and basal electrocardiogram (ECG) and echo-cardiography results were normal. Chemotherapy wasstarted with intravenous (i.v.) cisplatin 100 mg/m

Lipoplatin is a liposome encapsulated form of cisplatin. phase i studies on lipoplatin have demonstrated that the compound has an excellent toxicity profile. therefore we performed a phase ii trial in heavily pre-treated patients with advanced non-small-cell lung cancer (NSClC), performance status 0-2 in which the primary endpoint was response rate and secondary endpoints were safety and overall survival.Nineteen patients, average age 64 years old, with stage iV NSClC, were treated with lipoplatin 100 mg/m(2) every two weeks, as second line chemotherapy.We observed 1 partial remission (5.2%) and 3 stable diseases (15.9%). Time to progression (ttp) was 16 weeks and median overall survival (OS) was 31 weeks (7.2 months). We observed G1-G2 toxicity during chemotherapy, mainly gastrointestinal with nausea and vomiting (4 patients), asthenia (3 patients), mucositis (2 patients) and anemia (4 patients).Our phase ii study does not support a more extensive use of lipoplatin in phase III studies. An increase of dosage and a better selection of patients are mandatory to understand the real therapeutic activity of lipoplatin.

According to transplant registries, grafts from elderly donors have lower survival rates. During 1999-2005, we evaluated the outcomes of 89 patients who received a liver from a donor aged > or = 60 years and managed with the low liver-damage strategy (LLDS), based on the preoperative donor liver biopsy and the shortest possible ischemia time (group D > or = 60-LLDS). Group D > or = 60-LLDS was compared with 198 matched recipients, whose grafts were not managed with this strategy (89 donors < 60 years, group D < 60-no-LLDS and 89 donors aged > or =60 years, group D > or = 60-no-LLDS). In the donors proposed from the age group of > or =60 years, the number of donors rejected decreased during the study period and the LLDS was found to be responsible for this in a significant manner (47% vs. 60%, respectively P < 0.01). Among the recipients transplanted, the clinical features (age, gender, viral infection, child and model for end-stage liver disease score) were comparable among groups, but group D > or = 60-LLDS had a lower mean ischemia time: 415 +/- 106 min vs. 465 +/- 111 (D < 60-no-LLDS), P < 0.05 and vs. 476 +/- 94 (D > or = 60-no-LLDS), P < 0.05. After a median follow-up of 3 years, the 1- and 3-year graft survival rates of group D > or = 60-LLDS (84% and 76%) were comparable with group D < 60-no-LLDS (89% and 76%) and were significantly higher than group D > or = 60-no-LLDS (71% and 54%), P < 0.005. In conclusion, the LLDS optimized the use of livers from elderly donors.

GOAL OF THE WORK: Anemia is a common side effect of chemotherapy. Limited information exists about its incidence and risk factors. The objective of this study was to evaluate the incidence of anemia and risk factors for anemia occurrence in patients with early breast cancer who received adjuvant chemotherapy. MATERIALS AND METHODS: We evaluated risk factors for anemia in pre- and post/perimenopausal patients with lymph node-positive early breast cancer treated with adjuvant chemotherapy in two randomized trials. All patients received four cycles of doxorubicin and cyclophosphamide (AC) followed by three cycles of cyclophosphamide, methotrexate, fluorouracil (CMF). Anemia incidence was related to baseline risk factors. Multivariable analysis used logistic and Cox regression. MAIN RESULTS: Among the 2,215 available patients, anemia was recorded in 11% during adjuvant chemotherapy. Grade 2 and 3 anemia occurred in 4 and 1% of patients, respectively. Pretreatment hemoglobin and white blood cells (WBC) were significant predictors of anemia. Adjusted odds ratios (logistic regression) comparing highest versus lowest quartiles were 0.18 (P < 0.0001) for hemoglobin and 0.52 (P = 0.0045) for WBC. Age, surgery type, platelets, body mass index, and length of time from surgery to chemotherapy were not significant predictors. Cox regression results looking at time to anemia were similar. CONCLUSIONS: Moderate or severe anemia is rare among patients treated with AC followed by CMF. Low baseline hemoglobin and WBC are associated with a higher risk of anemia.

Aims and Background According to the USA Food and Drug Administration, quality of life (QOL) and/or survival are a priority for new anticancer drug approval. This study was performed to review approaches to QOL in randomized controlled clinical trials (RCCTs) and to survey the use of such measures in trials. Material and Methods A literature survey was carried out using the Medline/Medscape, Embase, Cochrane Library, and Ovid databases. Included in the survey were all publications in the set period (from 1966 to June 2005) with “quality of life” in the title or in the abstract in the field of “randomized, controlled clinical trials”. Each trial was evaluated according to the level of importance of QOL as a measure of outcome (primary, important and secondary) and was analyzed using the quality scoring system reported by Nicolucci et al. with some items regarding QOL. Results Four hundred and five RCCT articles in the oncology setting were found. Fifty-six of the 405 (13.8%) publications had QOL as primary end point. The overall quality score of these trials ranged from 40% to 100%, with a median overall score of 80%. The overall score was correlated with the year of publication (P = 0.007), the type of journal (P = 0.05), the presence of a biostatistician among the authors (P = 0.001), and the number of participating institutions (P = 0.009). Conclusions More attention to QOL in all components of RCCTs (design, choice of instruments, data management and processing) is required from both clinicians and statisticians.

BACKGROUND Others have reported ocular toxicity after adjuvant chemoendocrine therapy, but this study looked at ocular toxicity in similarly treated patients from large randomized clinical trials. METHODS Information was retrieved on incidence and timing of ocular toxicity from the International Breast Cancer Study Group (IBCSG) database of 4948 eligible patients randomized to receive tamoxifen or toremifene alone or in combination with chemotherapy (either concurrently or sequentially). Case reports of patients with ocular toxicity were evaluated to determine whether ocular toxicity occurred during chemotherapy and/or hormonal therapy. Additional information was obtained from participating institutions for patients in whom ocular toxicity occurred after chemotherapy but during administration of tamoxifen or toremifene. RESULTS Ocular toxicity was reported in 538 of 4948 (10.9%) patients during adjuvant treatment, mainly during chemotherapy. Forty-five of 4948 (0.9%) patients had ocular toxicity during hormone therapy alone, but only 30 (0.6%) patients had ocular toxicity reported either without receiving any chemotherapy or beyond 3 months after completing chemotherapy and, thus, possibly related to tamoxifen or toremifene. In 3 cases, retinal alterations, without typical aspects of tamoxifen toxicity, were reported; 4 patients had cataract (2 bilateral), 12 impaired visual acuity, 10 ocular irritation, 1 optical neuritis, and the rest had other symptoms. CONCLUSION Ocular toxicity during adjuvant therapy is a common side effect mainly represented by irritative symptoms due to chemotherapy. By contrast, ocular toxicity during hormonal therapy is rare and does not appear to justify a regular program of ocular examination. However, patients should be informed of this rare side effect so that they may seek prompt ophthalmic evaluation for ocular complaints. Cancer 2006. © 2005 American Cancer Society.

PURPOSE: A phase II trial investigated the activity and toxicity of a bolus administration schedule of oxaliplatin, fluorouracil (5-FU), and leucovorin (LV) therapy in patients with untreated advanced colorectal cancer. PATIENTS AND METHODS: Forty-five patients in this multicenter, open, nonrandomized study received oxaliplatin 130 mg/m2 on the first day of each course and 5-FU and LV 350 mg/m2 and 20 mg/m2, respectively, as a daily bolus for 5 days, every 21 days, for a maximum of six courses. RESULTS: Partial responses occurred in 18 patients, giving an intent-to-treat response rate of 40.0%. Median time to response was 12.7 weeks; median duration of response was 18.4 weeks. Median progression-free survival was 5.9 months; median survival was 14 months. The independent prognostic factors for improved overall survival were good performance status and negative carcino-embryonic antigen blood level. Incidences of adverse effects were reduced after the 5-FU dose was reduced to 300 mg/m2. Reversible neurologic toxicity occurred in 44.4% of patients. CONCLUSION: Bolus administration of oxaliplatin, 5-FU, and LV as first-line therapy for untreated advanced colorectal cancer is efficacious and safe. In addition to a more favorable safety profile, the 300 mg/m2 dosage offered improved dose-intensity compared with the initial dosage.

Up to now adjuvant chemotherapy after curative resection for gastric cancer (GC) has been considered an experimental approach. The results of existing phase III randomized trials comparing chemotherapy with control after surgery are controversial. Three meta-analyses have been published in recent years. It is likely that each of them presents a theoretical bias, mainly as regards the inclusion criteria of the trials. In this article we re-examine this potential bias, highlighting the differences between the present and past meta-analyses on adjuvant chemotherapy for GC.Only randomized controlled clinical trials comparing systemic adjuvant chemotherapy with control after radical resection of GC were eligible. Total mortality was assessed as outcome measure of the treatment effect and a pooled odds ratio was calculated using the Peto-Mantel-Haenszel method.After the selection process 17 papers (18 comparisons) proved eligible for inclusion in the meta-analysis with a total of 3118 patients, of whom 1546 randomized to the treatment arms and 1572 to the control arms; 762 and 871 deaths occurred in the treatment and control arms, respectively. Statistical analysis suggests an absence of significant heterogeneity between the trials and a significant advantage in survival for adjuvant chemotherapy (pooled odds ratio, 0.72, 95% Cl, 0.62-0.84).Our meta-analysis would seem to indicate that adjuvant chemotherapy results in a significant survival advantage in patients with GC. However, this observation undoubtedly requires confirmation in large randomized controlled trials including cisplatin before adjuvant chemotherapy after curative resection for GC can be proposed for use in clinical practice.

Background. Some trials have suggested that the combination of gemcitabine and platinum compounds can have a synergistic effect on several solid tumors, but, at present, the data concerning carboplatin-gemcitabine combinations are not sufficient to allow the planning of phase II trials. The present phase I trial was planned to define the maximum tolerated dose and the dose-limiting toxicity of a carboplatin-gemcitabine combination. Methods. Thirty-two patients with advanced, pretreated solid tumors were treated with carboplatin on day 1 and gemcitabine on days 1, 8, and 15 every 28 days. The starting doses of carboplatin and gemcitabine were 3.5 mg/ml per min (area under the curve; AUC), and 600 mg/m2, respectively. The doses of the two agents were alternately increased to 4, 4.5, and 5 mg/ml per min and to 800 and 960 mg/m2, respectively. At each dose level, three patients were initially enrolled. If one of them experienced grade IV hematological toxicity or grade III–IV nonhematological toxicity (with the exception of alopecia), an additional three patients were enrolled at the same dose level. If two or more patients experienced grade IV hematological toxicity or grade III–IV non-hematological toxicity (with the exception of alopecia), the maximum tolerated dose was considered to have been reached, and the dose below this was recommended for further studies. All patients were evaluated weekly for toxicity and after every two courses of chemotherapy for response. Results. Dose-limiting toxicity was hematological, and the maximum tolerated doses were 4.5 mg/ml per min for carboplatin and 800 mg/m2 for gemcitabine. The activity of the carboplatin/gemcitabine combination was encouraging, with a 21.9% response rate (7/32), three complete disease regressions, and a median time to progression of 30 weeks. The gemcitabine doses of day 15 or days 8 and 15 were omitted for hematological toxicity in 57 (50%) and 17 (14.9%) courses of chemotherapy, while no courses of chemotherapy were delayed for grade III–IV hematological or nonhematological toxicity. Conclusion. The maximum tolerated doses suggested by this trial are lower than those in other similar phase I trials, but they are consistent with those reported by most of the trials investigating gemcitabine either in combination with cisplatin or in heavily pretreated patients. Carboplatin 4.5 mg/ml per min on day 1 plus gemcitabine 800 mg/m2 on days 1, 8, and 15 every 28 days may represent a promising schedule for further phase II trials.

PURPOSE: Anticancer drugs may induce acute mucosal injury to stomach and duodenum. This study was planned to evaluate the efficacy of omeprazole or ranitidine in preventing such an injury. PATIENTS AND METHODS: Two hundred twenty-eight cancer patients with normal stomach and duodenum or with less than three erosions, who were selected to be treated with cyclophosphamide, methotrexate, and fluorouracil (90 breast carcinoma patients) or fluorouracil alone (138 colon carcinoma patients), were randomly assigned to treatment with omeprazole 20 mg, ranitidine 300 mg, or one placebo tablet a day. Seven days after the second course of chemotherapy (CT), the patients underwent a further esophagogastroduodenoscopy to evaluate the mucosal injury. Endoscopic findings were quantified on the basis of an arbitrary score, and the occurrence of epigastric pain or heartburn was assessed weekly. RESULTS: A significant difference was found among the three groups (P = .0032), as well as between pre- and postCT endoscopic findings (P = .00001). Endoscopic scores after CT were significantly higher than pretreatment scores in the placebo (P = .003) and ranitidine (P = .003) groups but not in the omeprazole group (P = .354). Acute ulcers were significantly less frequent in patients receiving omeprazole or ranitidine than in those receiving placebo (P = .0001 and P = .0315, respectively). Epigastric pain and/or heartburn were significantly less frequent in patients receiving omeprazole (P = .00124) or ranitidine (P = .038) than in those receiving placebo. CONCLUSION: Omeprazole is effective in preventing chemotherapy-induced gastroduodenal injury. Ranitidine is effective in reducing the frequency of ulcers and upper gastrointestinal symptoms but is not effective in preventing the global endoscopic worsening caused by chemotherapy. The different efficacy of omeprazole and ranitidine can be explained by their different pharmacodynamics.

This study involved 25 elderly (65 years old) patients (pts) with unresectable non small cell lung cancer (NSCLC) who were not eligible for polychemotherapy. The diagnosis of NSCLC was histologically or cytologically documented, and all of them had measurable or evaluable disease. The median age of the patients was 71 (range 65-77); 9 had been pretreated. The pts received 25 mg/m2 of vinorelbine weekly or bi-weekly depending on the results of blood tests. The treatment continued until disease progression or tolerance. No complete response was achieved: 3 pts (12%) had a partial response (RP) (8-12-14 months), 13 (52%) stable disease (SD) with an improvement in symptoms, such as cough and/or pain, and 9 pts (36%) progressed. Compliance with the therapy was acceptable. The main toxicity was hematological: neutropenia was observed in 16 pts, with only 1 case of grade 4 neutropenia without sepsis; grade 1-2 anemia occurred in 8 patients. The other toxicities included grade 1-2 neurotoxicity in 8 pts, chemical phlebitis in 2 pts and grade 3 cardiotoxicity reversible with medical treatment in 1 patient. The median survival time was 10 months (lower quartile 5 months, upper quartile 23 months) (Kaplan and Meyer method). Vinorelbine can be considered a rational choice in elderly pts with advanced NSCLC who are not suitable for aggressive polychemotherapy, with the aim of improving their quality of life in terms of symptoms and outpatient treatment.

3 weeks after commencing treatment with estramustine phosphate, typical manifestations of hemolytic-uremic syndrome occurred in a 66-year-old patient with prostate cancer. Urinary tract obstructions were excluded and no renal damage could be identified. An improvement in renal function was achieved by stopping estramustine phosphate and infusing adequate amounts of fluids and electrolytes. Anemia and thrombocytopenia also progressively improved after the discontinuation of chemotherapy. Nausea and vomiting, hepatotoxicity, impotence, reduced libido and hypercalcemia are major side effects of estramustine phosphate, and would be difficult to explain our observations without considering the role played by estramustine phosphate. Our observations suggest that estramustine phosphate might play either a direct role or produce a side effect within the context of latent paraneoplastic syndrome. The improvement in renal function which occurred when treatment stopped might confirm our hypothesis.

Aims and Background A registry-based cohort study of male patients with bladder cancer was conducted to determine the relative risk of second primary cancer of the prostate and kidney, the uni-/multivariate differences in relative risk according to patient characteristics, the cumulative risk by duration of the follow-up, and the prevalence:incidence ratio of prostate and kidney cancer cases detected in the first 6 months after the diagnosis of bladder cancer. Methods The complete case records of all male patients (n = 2025) diagnosed with bladder cancer between 1986 and 2002 were extracted from the database of the Romagna Cancer Registry: 1539 patients were eligible for analysis of the incidence of following prostate and kidney cancers, of the relative risk and the standardized incidence ratio specific for the time interval of follow-up. Results A total of 108 prostate cancer cases and 23 kidney cancer cases were observed during the follow-up. The relative risk of second primary cancer of the prostate and kidney was respectively 3.52 (95% CI, 2.89-4.25) and 3.90 (95% CI, 2.475.85). The absolute excess risk was 11.8 × 1000 for prostate cancer and 2.5 × 1000 for kidney cancer. The number of prevalent cases of prostate and kidney cancer detected was approximately 10 times greater than the expected number based on incidence rates from the general population. During the follow-up, incidence of prostate cancer stabilized at a level that was 3- to 4-fold greater than that expected. Despite fluctuations, a decrease was also observed for incidence of kidney cancer. Conclusions In summary, our study showed the relatively constant high incidence of prostate and kidney cancers in bladder cancer patients over time. The possibility of subsequent cancer implies that an appropriate long surveillance is required. The pertinence depends on the duration of the follow- up as well as the degree of surveillance.
