Prognostic Factors for Adrenocortical Carcinoma Outcomes.

PURPOSE: Adrenocortical carcinoma (ACC) is an aggressive tumor characterized by a high recurrence rate and poor response to treatment. This study analyzes a consecutive series of ACC patients to evaluate the prognostic value of various clinical and pathological characteristics. METHODS: We retrospectively evaluated 32 ACC patients followed at our Medical Center from 1997 to 2015 and evaluated the prognostic value of age at diagnosis, gender, tumor functional status, stage, and type of treatment with respect to overall survival (OS) and disease-free survival (DFS), as determined by Kaplan-Meier curves. RESULTS: ACC was associated with hormonal overproduction in 50% of cases, and patients with isolated hyperandrogenism had a better prognosis. Recurrence was observed in 12/26 (46.2%) patients with no evidence of disease after surgery. Tumor size [hazard ratio (HR) 1.32, 95% confidential intervals (CI) 1.12-1.64; p = 0.007], ki-67 (HR 1.06, 95% CI 1.02-1.11; p = 0.009) and advanced stage at diagnosis (III-IV) (HR 6.51, 95% CI 1.65-24.68; p = 0.006) were associated with recurrence in the 26 R0 patients in the univariate analysis. Advanced stage was an independent risk factor for recurrence in the multivariate analysis (HR 8.10, 95% CI 1.55-41.35; p = 0.01). Five-year survival was 40.0%. Positive resection margins (HR 10.61, 95% CI 3.02-38.31; p = < 0.001), ki-67 (HR 1.04, 95% CI 1.01-1.07; p = 0.01) and advanced stage (HR 11.31, 95% CI 1.45-87.76; p = 0.02) were associated with poor survival in all 32 patients, but only positive resection margins were an independent predictor of mortality in the multivariate analysis (HR 6.22, 95% CI 1.44-26.05; p = 0.01). CONCLUSION: ACC has a poor prognosis with a high recurrence rate. Tumor stage at diagnosis and the completeness of surgical excision are the most relevant prognostic factors.

Clinical activity and tolerability of FOLFIRI and cetuximab in elderly patients with metastatic colorectal cancer in the CAPRI-GOIM first-line trial.

BACKGROUND: In the cetuximab after progression in KRAS wild-type colorectal cancer patients (CAPRI) trial patients with metastatic colorectal cancer (mCRC) received 5-fluorouracil, folinic acid and irinotecan (FOLFIRI) and cetuximab in first line followed by 5-Fluorouracil, folinic acid, oxaliplatin (FOLFOX) with or without cetuximab until progression. Limited data are available on the efficacy and safety of anti-epidermal growth factor receptor (anti-EGFR) agents on elderly patients with mCRC. In the current study we evaluated the efficacy and safety of FOLFIRI plus cetuximab in age-defined subgroups. METHODS: A post-hoc analysis was performed in CAPRI trial patients; outcomes (progression-free survival (PFS), overall response rate (ORR), safety) were analysed by age-groups and stratified according to molecular characterisation. 3 age cut-offs were used to define the elderly population (≥65; ≥70 and ≥75 years). RESULTS: 340 patients with mCRC were treated in first line with FOLFIRI plus cetuximab. Among those, 154 patients were >65 years, 86 >70 years and 35 >75 years. Next-generation sequencing (NGS) was performed in 182 patients. Among them, 87 patients were >65 years, 46 >70 and 17 >75. 104 of 182 patients were wild type (WT) for KRAS, NRAS, BRAF, PIK3CA genes. In the quadruple WT group, 51 patients were ≥65 years; 29 were ≥70; 9 were ≥75. Median PFS was similar within the age-subgroups in the intention-to-treat population, NGS cohort and quadruple WT patients, respectively. Likewise, ORR was not significantly different among age-subgroups in the 3 populations. Safety profile was acceptable and similarly reported among all age-groups, with the exception of grade ≥3 diarrhoea (55% vs 25%, p=0.04) and neutropaenia (75% vs 37%, p=0.03) in patients ≥75 years and grade ≥3 fatigue (31% vs 20%, p=0.01) in patients <75 years. CONCLUSIONS: Tolerability of cetuximab plus FOLFIRI was acceptable in elderly patients. Similar ORR and PFS were observed according to age-groups. No differences in adverse events were reported among the defined subgroups with the exception of higher incidence of grade ≥3 diarrhoea and neutropaenia in patients ≥75 years and grade ≥3 fatigue in patients <75 years.

The BRAF(V600E) mutation influences the short- and medium-term outcomes of classic papillary thyroid cancer, but is not an independent predictor of unfavorable outcome.

INTRODUCTION: The prognostic usefulness of BRAF(V600E) evaluation in papillary thyroid cancer (PTC) has been analyzed in many studies, with controversial conclusions. AIM: To analyze the clinical relevance of BRAF(V600E) measurement in a homogenous series of PTC patients followed in a single institution. METHODS: One hundred three classical variant PTC patients who underwent total thyroidectomy in the 3-year period between 2005 and 2008 were retrospectively selected, and BRAF(V600E) assessment was performed using paraffin-embedded archival specimens in 2013. All patients were actively followed at our medical center, with an average follow-up of 55±13 months. RESULTS: BRAF(V600E) mutation-positive cancers (55.3%) were more frequently associated with lymph node metastasis (p=0.01) and advanced TNM stage (III-IV) (p=0.03). These findings were also confirmed in the subset of 42 microcarcinomas. BRAF(V600E)-positive patients were also at a higher risk of persistent disease (OR 3.5 [95% confidence interval {CI} 1.2-10.3], p=0.03) in univariate but not multivariate analysis (OR 2.8 [CI 0.7-11.8], p=0.2). Lymph node involvement was an independent predictor of persistent disease (OR 30.9 [CI 6.0-159.0], p<0.0001). Kaplan-Meier curves confirmed a higher percentage of persistent/recurrent disease in BRAF(V600E)-positive patients (p=0.02). However, the BRAF(V600E) mutation did not change the recurrence rate of PTC in subgroup analyses on the basis of other established risk factors (p=0.2). CONCLUSIONS: BRAF(V600E)-positive tumors were at higher risk of developing more aggressive behavior and were associated with less favorable outcomes in the short and medium term, but the BRAF(V600E) mutation was not an independent predictor of unfavorable outcome. Therefore, its use as a prognostic marker in clinical practice is not advisable.

Fludarabine, mitoxantrone and dexamethasone as front-line therapy in elderly patients affected by newly-diagnosed, low-grade non-Hodgkin's lymphomas with unfavorable prognostic factors: results of a phase II study.

About one-third of the cases of non-Hodgkin's lymphomas occur in patients aged 60 years or more. Nevertheless, there are very few data in the literature regarding the optimal therapeutic approach for both aggressive and indolent histologies. Fludarabine-based combination regimens are an effective choice for younger patients affected by low-grade non-Hodgkin's lymphomas, but there is a lack of information about their tolerability and efficacy in older patients. We performed a phase II study to test the efficacy and safety of the combination of Fludarabine, Mitoxantrone and Dexamethasone (FND) in newly-diagnosed, chemo-naive elderly patients affected by low-grade non-Hodgkin's lymphomas with unfavorable prognostic factors. From March 1999 to March 2002, 18 patients were enrolled into the study. All the patients were evaluated for toxicity and response. Neutropenia and thrombocytopenia have been registered as the main toxicities. Thirteen (72%) patients experienced a complete response and 4 (22%) a partial response: the overall response rate was 94%. At a median follow-up of 19 months, the median time for progression-free-survival and the median survival time were not reached yet. The 2-years projected progression-free-survival and overall-survival are 52% and 67% respectively. When administered as first-line treatment to a population of elderly patients affected by high-risk, low-grade non-Hodgkin's lymphomas, FND showed a high efficacy and a good toxicity profile. Our data compare favorably to those reported for the same schedule administered both as first- or second-line therapy in younger patients.
