To define the optimal initial management and the best extent of surgery that would optimize margins on primary retroperitoneal sarcomas (RPS).
A total of 382 patients with primary RPS were analyzed. ...Sixty-five patients had a simple resection of the tumor, 120 patients had a complete compartmental resection (systematic resection of noninvolved contiguous organs), 130 patients had a contiguously involved organ resection, 21 patients had a systematic re-excision, 38 patients had an incomplete gross resection, and eight patients had a biopsy alone. Radiotherapy and chemotherapy were administered to 121 and 145 patients, respectively.
One, 3-, and 5-year overall survival (OS) rates were 86% (95% CI, 0.82 to 0.89), 66% (95% CI, 0.61 to 0.71), and 57% (95% CI, 0.51 to 0.62), respectively. Median overall survival was 6 years. In the multivariate analysis, high grade, tumor rupture, gross residual disease, and positive margins were associated with decreased OS. Low grade, no tumor rupture, negative histologic margins, a high number of patients undergoing operation per center, and compartmental resection compared with standard procedures were associated with decreased abdominal recurrences. Compartmental resection is a significant variable, predicting a 3.29-fold lower rate of abdominal recurrence compared with simple complete resection.
Complete compartmental surgery without tumor rupture should be performed when possible to achieve clear margins. This surgery should be performed in a high-volume center. The role of adjuvant treatments should be evaluated in a randomized trial in association with this optimal surgery.
Cadmium, lead, mercury and chromium concentrations in fish muscle tissue taken from various Sicilian areas were detected. Fish caught in Siracusa, nearby a petrochemical industrial area, were more ...contaminated by cadmium, lead and chromium (respectively 0.366, 0.32, 0.72 μg/g) than those from the other sites. In the Sicily Channel, we found the highest bioaccumulation of mercury (0.31 μg/g). Although some metals concentrations exceed the limits set by the European regulation, the estimated weekly intake was below the Provisional Tolerable Weekly Intake established by the European Food and Safety Authority, and the Target Hazard Quotient values indicate that there is no carcinogenic risk for humans.
Full-dose reirradiation combined with chemotherapy has been shown to be feasible after salvage surgery with acceptable toxicity. The Groupe d'Etude des Tumeurs de la Tête et du Cou and Groupe ...d'Oncologie Radiothérapie Tête Et Cou groups performed a randomized study to assess its efficacy.
Between 1999 and 2005, 130 patients with head and neck cancer were treated with salvage surgery and randomly assigned to full-dose reirradiation combined with chemotherapy (RT arm) or to observation (a "wait and see" approach; WS arm). Eligibility criteria were recurrence or a second primary tumor in a previously irradiated area, no major sequelae resulting from the first radiotherapy, good general condition, no distant metastasis, and salvage surgery with macroscopic complete resection. Patients in the RT arm received 60 Gy over 11 weeks combined with concomitant fluorouracil and hydroxyurea.
Sixty-five patients were randomly assigned to each arm. There was no imbalance in the distribution of the main tumor and patients characteristics. The most serious acute toxicity in the RT arm was mucositis, attaining grade 3 or 4 in 28% of patients. At 2 years, 39% of patients in the RT arm and 10% in the WS arm experienced grade 3 or 4 late toxicity according to Radiation Therapy Oncology Group criteria (P = .06). Disease-free survival (DFS) was significantly improved in the RT arm, with a hazard ratio of 1.68 (95% CI, 1.13 to 2.50; P = .01), but overall survival (OS) was not statistically different.
Full-dose reirradiation combined with chemotherapy after salvage surgery significantly improved DFS, but had no significant impact on OS. An increase in both acute and late toxicity was observed.
The aim was to investigate whether germline polymorphisms within candidate genes known or suspected to be involved in fluorouracil (FU), oxaliplatin, and irinotecan pathways were associated with ...toxicity and clinical outcome in patients with metastatic colorectal cancer (mCRC).
Blood samples from 349 patients included in the Fédération Francophone de Cancérologie Digestive 2000-05 randomized trial, which compared FU plus leucovorin (LV5FU2) followed by FU, leucovorin, and oxaliplatin (FOLFOX) followed by FU, leucovorin, and irinotecan (FOLFIRI; sequential arm) with FOLFOX followed by FOLFIRI (combination arm) in terms of progression-free survival (PFS) and overall survival, were collected. Twenty polymorphisms within the DPD, TS, MTHFR, ERCC1, ERCC2, GSTP1, GSTM1, GSTT1, and UGT1A1 genes were genotyped.
The ERCC2-K751QC allele was independently associated with an increased risk of FOLFOX-induced grade 3 or 4 hematologic toxicity (P = .01). In the sequential arm, TS-5'UTR3RG and GSTT1 alleles were independently associated with response to LV5FU2 (P = .009) and FOLFOX (P = .01), respectively. The effect of oxaliplatin on tumor response increased with the number of MTHFR-1298C alleles (test for trend, P = .008). The PFS benefit from first-line FOLFOX was restricted to patients with 2R/2R (hazard ratio HR = 0.39; 95% CI, 0.23 to 0.68) or 2R/3R (HR = 0.59; 95% CI, 0.42 to 0.82) TS-5'UTR genotypes, respectively. Conversely, patients with the TS-5'UTR 3R/3R genotype did not seem to benefit from the adjunction of oxaliplatin (HR = 0.96; 95% CI, 0.66 to 1.40; trend between the three HRs, P = .006).
A pharmacogenetic approach may be a useful strategy for personalizing and optimizing chemotherapy in mCRC patients and deserves confirmation in additional prospective studies.
Estimates of cancer prevalence are widely based on limited duration, often including patients living after a cancer diagnosis made in the previous 5 years and less frequently on complete prevalence ...(i.e., including all patients regardless of the time elapsed since diagnosis). This study aims to provide estimates of complete cancer prevalence in Italy by sex, age, and time since diagnosis for all cancers combined, and for selected cancer types. Projections were made up to 2020, overall and by time since diagnosis.
Data were from 27 Italian population-based cancer registries, covering 32% of the Italian population, able to provide at least 7 years of registration as of December 2009 and follow-up of vital status as of December 2013. The data were used to compute the limited-duration prevalence, in order to estimate the complete prevalence by means of the COMPREV software.
In 2010, 2,637,975 persons were estimated to live in Italy after a cancer diagnosis, 1.2 million men and 1.4 million women, or 4.6% of the Italian population. A quarter of male prevalent cases had prostate cancer (n = 305,044), while 42% of prevalent women had breast cancer (n = 604,841). More than 1.5 million people (2.7% of Italians) were alive since 5 or more years after diagnosis and 20% since ≥15 years. It is projected that, in 2020 in Italy, there will be 3.6 million prevalent cancer cases (+ 37% vs 2010). The largest 10-year increases are foreseen for prostate (+ 85%) and for thyroid cancers (+ 79%), and for long-term survivors diagnosed since 20 or more years (+ 45%). Among the population aged ≥75 years, 22% will have had a previous cancer diagnosis.
The number of persons living after a cancer diagnosis is estimated to rise of approximately 3% per year in Italy. The availability of detailed estimates and projections of the complete prevalence are intended to help the implementation of guidelines aimed to enhance the long-term follow-up of cancer survivors and to contribute their rehabilitation needs.
Summary Background The optimum use of cytotoxic drugs for advanced colorectal cancer has not been defined. Our aim was to investigate whether combination treatment is better than the sequential ...administration of the same drugs in patients with advanced colorectal cancer. Methods In this open-label, randomised, phase 3 trial, we randomly assigned patients (1:1 ratio) with advanced, measurable, non-resectable colorectal cancer and WHO performance status 0–2 to receive either first-line treatment with bolus (400 mg/m2 ) and infusional (2400 mg/m2 ) fluorouracil plus leucovorin (400 mg/m2 ) (simplified LV5FU2 regimen), second-line LV5FU2 plus oxaliplatin (100 mg/m2 ) (FOLFOX6), and third-line LV5FU2 plus irinotecan (180 mg/m2 ) (FOLFIRI) or first-line FOLFOX6 and second-line FOLFIRI. Chemotherapy was administered every 2 weeks. Randomisation was done centrally using minimisation (minimisation factors were WHO performance status, previous adjuvant chemotherapy, number of disease sites, and centre). The primary endpoint was progression-free survival after two lines of treatment. Analyses were by intention-to-treat. This trial is registered at ClinicalTrials.gov , NCT00126256. Findings 205 patients were randomly assigned to the sequential group and 205 to the combination group. 161 (79%) patients in the sequential group and 161 (79%) in the combination group died during the study. Median progression-free survival after two lines was 10·5 months (95% CI 9·6–11·5) in the sequential group and 10·3 months (9·0–11·9) in the combination group (hazard ratio 0·95, 95% CI 0·77–1·16; p=0·61). All six deaths caused by toxic effects of treatment occurred in the combination group. During first-line chemotherapy, significantly fewer severe (grade 3–4) haematological adverse events (12 events in 203 patients in sequential group vs 83 events in 203 patients in combination group; p<0·0001) and non-haematological adverse events (26 events vs 186 events; p<0·0001) occurred in the sequential group than in the combination group. Interpretation Upfront combination chemotherapy is more toxic and is not more effective than the sequential use of the same cytotoxic drugs in patients with advanced, non-resectable colorectal cancer.

The complexity of understanding cancer risk in MS is increased by inconsistencies in study design, and the lack of age-, sex-, and ethnicity-specific risk estimates. Aims of our study were to ...estimate the incidence of cancers in the MS population of Catania (Italy) and to evaluate the impact of disease-modifying treatments (DMTs) in cancer risk.
We screened 2,730 PwMS according to the MS criteria of Mc Donald 2010 referring to MS center of Catania in the period between 2003 and 2013. We matched database of MS patients with the Integrated Cancer of Catania-Messina-Siracusae-Enna. We calculated age and sex specific standardized incidence ratios (SIR) and the relative risk (RR) of developing cancer in MS patients treated with at least two different DMTs compared to who received one or no treatment.
Out of 2,730, 1,180 MS patients (67.1% females; mean age 41.2 ± 12.9) were enrolled. We found 36 cancers. Global SIR was 1.18 (CI95% 0.78-1.58), with a significantly higher risk in men with a range age of 20 to 50 years 2.84; (CI95% 1.59-4.09) and in women over 50 years 1.82 (CI95% 1.08-2.55). RR of developing cancer was 1.99 (CI95% 1.14-3.45) in MS patients switching one DMT and 3.38 (CI95% 1.83-6.22) in who switched at least twice.
Our results demonstrated that cancer risk was not increased in our MS population; but age and sex different distribution may partly drive cancer risk. Higher cancer risk in MS patients switching more than two DMTs should take into account in treatment decision making.
The aim of this study is to describe the frequency and trend of pregnancy-associated cancer (PAC) in Italy, an increasingly relevant phenomenon due to postponing age at childbirth. To this purpose, a ...population-based retrospective longitudinal study design based on cohorts of women aged 15–49 diagnosed with cancer and concomitant pregnancy is proposed. The study uses 19 population-based Cancer Registries, covering about 22% of Italy, and linked at an individual level with Hospital Discharge Records. A total of 2,861,437 pregnancies and 3559 PAC are identified from 74,165 women of the cohort with a rate of 1.24 PAC per 1000 pregnancies. The most frequent cancer site is breast (24.3%), followed by thyroid (23.9%) and melanoma (14.3%). The most frequent outcome is delivery (53.1%), followed by voluntary termination of pregnancy and spontaneous abortion (both 12.0%). The trend of PAC increased from 2003 to 2015, especially when the outcome is delivery, thus confirming a new attitude of clinicians to manage cancer throughout pregnancy. This represents the first attempt in Italy to describe PAC from Cancer Registries data; the methodology is applicable to other areas with the same data availability. Evidence from this study is addressed to clinicians for improving clinical management of women with PAC.
Increased success in the treatment of hematological cancers contributed to the increase of 5-year survival for most adolescent and young adults (AYAs) with these tumours. However, as 5-year survival ...increased, it became clear that AYA long-term survivors were at increased risk for severe late effects. Moreover, limited information on long-term cancer impact is available for AYAs, since most studies focused on children and adolescents. We aimed to assess various long-term outcomes on AYA survivors of hematological cancers.
We selected patients diagnosed with a first primary hematological cancer between 1997 and 2006, in the Italian nationwide population-based cohort of AYA cancer survivors (i.e. alive at least 5 years after cancer diagnosis). Long-term outcomes of interest were: second malignant neoplasms (SMNs), hospitalizations and overall mortality. We calculated standardized incidence ratios (SIRs), standardized hospitalization rate ratios (SHRs) and standardized mortality rate ratios (SMRs). To study morbidity patterns over time, we modeled observed incidence rates by fitting flexible parametric models for nonlinear patterns and we used linear regression for linear patterns.
The study cohort included 5,042 AYA hematological cancer survivors of which 1,237 and 3,805 had a leukaemia and lymphoma diagnosis, respectively. AYA survivors were at substantially increased risk for SMN (SIR=2.1; 95%CI=1.7; 2.6), hospitalisation (SHR=1.5; 95%CI=1.5; 1.6), and mortality (SMR=1.4; 95%CI=1.2; 1.6) with differences between leukaemia and lymphoma survivors. The highest excess risks of hospitalisations were for infectious diseases, respiratory diseases, and diseases of blood and blood-forming organs. The morbidity pattern differs over time by morbidity type.
Our results support the need for strict follow-up plans for survivors, and call for further study to better personalised follow-up plans for AYA cancer survivors.
To progress in the stratification of the first-line therapeutic management of metastatic adrenocortical carcinoma (ACC), we searched for prognostic parameters of survival in patients treated with ...combined mitotane- and cisplatinum-based chemotherapy as first-line. We retrospectively studied prospectively collected parameters from 131 consecutive patients with metastatic ACC (44 with a tissue specimen available) treated at the Gustave Roussy Institute with mitotane- and platinum-based chemotherapy. Fifty-five patients with clinical, pathological, and morphological data available together with treatment characteristics including detailed follow-up were enrolled. Plasma mitotane levels and ERCC1 protein staining were analyzed. Response was analyzed according to RECIST criteria as well as overall survival (OS) from the start of cisplatinum-based chemotherapy. Parameters impacting on OS were evaluated by univariate analysis, and then analyzed by multivariate analysis. Using a landmark method, OS according to response to chemotherapy was analyzed. Objective response to combined mitotane- and cisplatinum-based chemotherapy was 27.3%. Median OS was 1 year. In the univariate analysis, resection of the primary, time since diagnosis, mitotane monotherapy as single first-line treatment, number of affected organs, plasma mitotane above 14 mg/l, and objective response were predictors of survival. In the multivariate analysis, mitotane level > or =14 mg/l and objective response to platinum-based chemotherapy were found to be independent predictors of survival (P=0.03 and <0.001). Our study suggests a prognostic role for mitotane therapy and objective response to platinum-based chemotherapy.
