Mosaic Study: Actualization of Overall Survival (Os) with 10 Years Follow Up and Evaluation of Braf. By Gercor and Mosaic Investigators
2014
ABSTRACT Aim: The MOSAIC study (Andre T, N Engl J Med, 2004) has demonstrated in patients with stage II/III resected colon cancer (CC) a benefit of oxaliplatin added to 5FU and LV (LV5FU) in 3-year disease-free survival (DFS) and in overal survival (OS). LV5FU and oxaliplatin (FOLFOX4) has also shown a benefit in deficient MisMatch Repair (dMMR) CC pts (Flejou JF, J Clin Oncol 31: 2013;suppl; abstr 3524). We report here 1) Results of MOSAIC after 10 year follow-up, and 2) results in the BRAF evaluable population. Methods: Of the 2246 patients included in the MOSAIC study (whole population), the actualization of survival data was done with 10 yrs follow up. Formalin-fixed, paraffin-embedded …
Impact of neoadjuvant chemotherapy on survival in breast cancer patients in daily practice: a population-based study
2013
This population-based study aimed to describe the effects of neoadjuvant chemotherapy (NC) on survival in breast cancer (BC) patients in daily practice. BC patients treated with NC followed by surgery and radiotherapy, were retrospectively selected from 1982 to 2005 using the Cote d’Or BC registry. These patients were matched for the baseline AJCC (American Joint Committee on Cancer) stage, age at diagnosis, date of diagnosis and oestrogens receptors status to those who had undergone surgery followed by adjuvant chemotherapy and radiotherapy. The prognostic effect of NC on survival in BC patients was assessed with relative survival (RS) analyses. From 1982 to 2005, 210 patients with BC diag…
Serum coding and non-coding RNAs as biomarkers of NAFLD and fibrosis severity
2019
Background: In patients with NAFLD liver biopsy is the gold standard to detect NASH and stage liver fibrosis. We aimed to identify differentially expressed mRNAs and non-coding RNAs in serum samples of biopsy-diagnosed mild and severe NAFLD patients with respect to controls and to each other. Methods: We first performed a whole transcriptome analysis through microarray (n=12: 4 CTRL; 4 mild NAFLD: NAS≤4 F0; 4 severe NAFLD NAS≥5 F3), followed by validation of selected transcripts through qPCRs in 88 subjects: 63 NAFLD, 25 CTRL. A similar analysis was also performed on HepG2 exposed to Oleate:Palmitate or only Palmitate (cellular model of NAFL/NASH) at intracellular/extracellular levels. Tran…
Gastric and Rectal Metastases from Malignant Melanoma Presenting with Hypochromic Anemia and Treated with Immunotherapy
2017
The authors present a case of an 80-year-old Caucasian male with multiple gastric and rectal metastases from malignant melanoma presenting with hypochromic anemia as the sole symptom of disease without evidence of cutaneous and ocular tumor localization. The patient had a medical history positive for malignant lentigo melanoma of the occipital region of the scalp and early stage laryngeal squamous cell carcinoma and prostatic carcinoma treated with radiation therapy. The authors make some considerations on intestinal involvement by metastatic melanoma and discuss the choice of not treating with endoscopic procedures the gastric metastatic lesions most likely responsible for the clinical sig…
Perioperative Chemotherapy in Poorly Differentiated Neuroendocrine Neoplasia of the Bladder: A Multicenter Analysis
2020
There is scant evidence about optimal management of poorly differentiated neuroendocrine carcinoma of the bladder (BNEC). We performed a multicenter retrospective study on BNEC patients from 13 Italian neuroendocrine-dedicated centers to analyze strategies associated with better outcomes. Mixed adeno-neuroendocrine carcinomas (MANEC) were included. We analyzed overall survival (OS) in the overall cohort, relapse-free survival (RFS) in radically operated patients and progression-free survival (PFS) in patients who received chemotherapy for metastatic disease. Fifty-one BNEC patients were included (male: 46, median age: 70 years). Overall, median OS was 16.0 months, radical tumor resection wa…
Neoadjuvant chemotherapy for stage IIIA-N2 non-small cell lung cancer
2005
Neoadjuvant chemotherapy in potentially resectable stage IIIA-N2 non-small cell lung cancer (NSCLC) has become standard of treatment in the last years. Two randomised pioneer phase III trials conducted with second generation platinum combinations had demonstrated an advantage in survival of induction chemotherapy followed by surgery versus surgery alone. Subsequently, a wide number of phase II studies with third generation platinum-based doublets or triplets have increased the evidence of the activity as well as the good tolerability of this approach. Nowadays, the main topics of ongoing clinical research are to assess the role of induction chemotherapy in early stage disease, and the role …
Mandibular Brown Tumor as a Result of Secondary Hyperparathyroidism: A Case Report with 5 Years Follow-Up and Review of the Literature
2021
Background: Brown tumor is a rare skeletal manifestation of secondary hyperparathyroidism. Although diagnosis of the disease is increasingly seen in early stages due to improved screening techniques, some patients still present in a progressed disease stage. The treatment depends on tumor mass and varies from a conservative approach with supportive parathyroidectomy to extensive surgical resection with subsequent reconstruction. Case presentation: We report a case of extensive mandibular brown tumor in a patient with a history of systemic lupus erythematosus, chronic kidney disease, and secondary hyperparathyroidism. Following radical resection of the affected bone, reconstruction could be …
Lack of association between proliferative verrucous leukoplakia and human papillomavirus infection.
2005
Purpose To analyze proliferative verrucous leukoplakia (PVL) for the presence of human papillomavirus (HPV) in different stages of the disease. Materials and Methods We studied 13 patients with PVL. In 10 patients (76.9%), a lesional biopsy was taken and frozen at −40°C. Four patients were instructed to mouth rinse with sterile sera. The biopsy and rinse samples were analyzed for HPV by PCR. Results We did not detect HPV infection in the PVL tissue or in the oral rinse of any of the 13 patients in any stage of the disease analyzed, neither in oral squamous cell carcinoma nor in the simple hyperkeratosis. Conclusion There was no association between PVL and HPV infection in our patients.
Automated DNA-image cytometry: a prognostic tool in infiltrating bladder carcinoma?
1987
In a retrospective study, paraffin-embedded cystectomy specimens obtained from 46 patients with bladder cancer (stage pT1 — pT4a, pN0, pN2) were analysed for tumor DNA ploidy and proliferation using automated image cytometry (LEYTAS). In 41 cases, DNA ploidy could be measured. Estimation of proliferation was possible in 26 tumors. The number of cells with a DNA content higher than 5C could be calculated in 38 of the tumors. All these three parameters are shown to correlate with patient outcome.
Clinicopathologic and DNA Flow Cytometric Analysis of Eighty-three Renal Cell Carcinomas
1995
The clinical and anatomopathologic features as well as DNA content of 83 renal cell carcinomas were analyzed. The possible interrelationship and prognostic value of these factors were also considered. The DNA study has been performed by flow cytometry using paraffin-embedded tissues. In each case an internal control with nonneoplastic renal tissue obtained in the same nefrectomy was also done in order to calculate the DNA index. Differences in patient age, nuclear grade, and mitotic activity were related with outcome; however, this relationship was not confirmed by the Cox test. Stage (P = .005), cell type (P = .002), and metastatic disease (P = .001) had independent prognostic values. Ren…
