A multi-element psychosocial intervention for early psychosis (GET UP PIANO TRIAL) conducted in a catchment area of 10 million inhabitants: study protocol for a pragmatic cluster randomized controlled trial

Multi-element interventions for first-episode psychosis (FEP) are promising, but have mostly been conducted in non-epidemiologically representative samples, thereby raising the risk of underestimating the complexities involved in treating FEP in 'real-world' services

Incidence and clinical impact of sterilized disease and minimal residual disease after preoperative radiochemotherapy for rectal cancer

In advanced rectal cancer, chemoradiation can induce downstaging until complete disappearance of the tumor or its persistence in minimal form. The complete sterilized and the minimal residual disease often are considered similar. We evaluated the specific incidence of these two conditions and analyzed their impact in terms of local recurrence, distant metastasis, and survival. METHODS: We studied 139 uT3/T4 N0/N+ rectal cancers, treated with preoperative chemoradiation and curative surgery after six to eight weeks. We evaluated ypTNM stage and tumoral regression, according to the five degrees proposed by Dworak, with special attention to 4 and 3 (sterilized and minimal residual disease). RESULTS: Tumor downstaging occurred in 65 patients (46.7 percent), including 25 sterilized lesions (17.9 percent) and 24 minimal residual disease (17.2 percent). In median follow-up of 30 months, none of the patients with sterilized disease developed local or distant recurrence. Among patients with minimal residual disease, none developed local recurrence, whereas two (8.3 percent) developed distant metastasis, and one died from disease. In patients with gross residual disease (Grade 2, 1, 0) the percentage of local recurrence was 8.8 percent, distant recurrence 26.6 percent, and 13.3 percent died from disease. The difference between three groups is statistically significant as regards local and distant recurrence. CONCLUSIONS: After preoperative therapy, the sterilized disease shows an excellent prognosis. The minimal residual disease has an important numeric incidence. Its outcome is different, with a not-negligible risk of distant recurrence. The minimal residual disease has a much better prognosis in comparison with the gross residual diseas

Prognostic value of Dworak grade of regression (GR) in patients with rectal carcinoma treated with preoperative radiochemotherapy

Preoperative radiochemotherapy improves local control in locally advanced rectal cancer; however, its role in prolonging survival is still controversial. In order to better define the subset in patients who might benefit from this multimodal treatment, we have evaluated the correlation between grade of regression (GR) to preoperative treatment and disease-free survival (DFS). METHODS: We reviewed retrospectively the surgical specimens of 106 patients with locally advanced T3/T4 N0/ M0 rectal cancer. All patients were treated preoperatively with radiotherapy and 5-fluorouracil-based regimen chemotherapy. We evaluated ypTNM stage, and tumor regression was graded using the Dworak system that varies from GR 0 (absence of regression) to GR 4 (complete regression). RESULTS: GR was as follows: GR 4, 16 patients (15%); GR 3, 25 patients (23.6%), GR 2, 30 patients (28.4%), GR 1, 32 patients (30.2%) and GR 0, 3 patients (2.8%). A significant correlation was found between GR and DFS. Three-year DFS was 100, 85, 82, 66 and 33% in GR 4, 3, 2, 1 and 0, respectively (p=0.01). DFS was significantly lower in patients with advanced stages at diagnosis and in patients without down-staging. Moreover, in postoperative stage II and III cases, GR 3 correlated with a better DFS than GR 2-0 (p=0.2 and p=0.4, respectively). CONCLUSIONS: The GR was a significant prognostic factor in locally advanced rectal carcinoma treated with preoperative chemoradiotherapy. The pathological stage and down-staging also have prognostic value. The use of a standardized system to evaluate GR in rectal cancer can allow for comparisons between different institutions and can identify patients at worse prognosis to be treated with adjuvant therap
