Colorectal cancer remains a major cause of cancer mortality in the Western world both in men and women. In this manuscript a concise overview and recommendations on adjuvant chemotherapy in colon cancer are presented. An executive team from the Hellenic Society of Medical Oncology was assigned to develop a consensus statement and guidelines on the adjuvant treatment of colon cancer. Fourteen statements on adjuvant treatment were subjected to the Delphi methodology. Voting experts were 68. All statements achieved a rate of consensus above than 80% (>87%) and none revised and entered to a second round of voting. Th ree and 8 of them achieved a 100 and an over than 90% consensus, respectively. These statements describe evaluations of therapies in clinical practice. They could be considered as general guidelines based on best available evidence for assistance in treatment decision-making. Furthermore, they serve to identify questions and targets for further research and the settings in which investigational therapy could be considered. © 2016 Hellenic Society of Gastroenterology.

Background: Hypofractionated Radiotherapy (RT) regimens for breast cancer, although reduce cost and time for patients and health care systems, could have a negative impact on normal underlying lung tissue. We studied and compared lung function and the post-RT radiological changes using High-Resolution Computed Tomography (HRCT) in early breast cancer patients, treated with 3-Dimentional conformal whole breast radiotherapy (WBRT) using either conventional or hypofractionated regime. Patients and Methods: Between 2008 and 2009, 61 early breast cancer patients (T1-2N0M0) were randomised into two groups. Group A (n=31) received standard radiotherapy with 50Gy/25f/5w plus boost 10Gy/5f/1w to tumour bed. Group B (n=30) received 43.2Gy/16f/22d plus boost 10Gy/5f/1w to tumour bed. Patients of both groups were subjected to dynamic lung testing, using spirometry and gas diffusion tests on Day 0 (D0, before RT), during RT and after completion of RT at 3 and 6 months. HRCT scans were performed in all patients at baseline, and 3,6,12 months after completion of RT. Respiratory symptoms were recorded at 3 and 6 months post completion of RT. Dosimetric factors, such as Central Lung Dose (CLD), lung Volume receiving more 20 Gy (V20), D25 and Mean Lung Dose (MLD) were calculated for all patients. Results: At 3 months after RT, the pulmonary changes were classified at HRCT as follows: 91.8 % were Grade 0, 8.19 % Grade 1, and 0 % Grade 2. At 6 months, 86.98 % were Grade 0, 11.47 % Grade 1, and 1.6 % Grade 2. At 12 months, 88.52 % were Grade 0, 9.19 % Grade 1 and 3.27% Grade 2. Univariate analysis showed strong association between radiation pneumonitis, age and all dosimetric parameters. There was no association between fractionation type and incidence of RN. FEV1, FVC, FEV 25, FEV 50 and DLCO showed no statistically significant reduction in both treatment groups in 3 and 6 months following completion of RT, compared to baseline. Multivariate analysis showed no relation between HRCT findings and other variables (age, smoking, chemotherapy, hormonotherapy, V20) Conclusion: Lung toxicity, as assessed with HRCT and PFTs, was minimal in both treatment arms and our results are in consistency with other published data. Hypofractionated RT was a safe modality and well tolerated by the majority of the patients. Longer follow-up is required for robust assessment of incidence of late lung fibrosis in our series.

Hyperthermia has been included in the 2013 National Comprehensive Cancer Network (NCCN) guidelines as an option for the treatment of breast recurrences. The purpose of this article is to demonstrate the important role of hyperthermia as a therapeutic modality by presenting clinical trials on this subject carried out in the last decades. Materials and Methods: All relevant trials published since 1987 were retrieved from Medline and reviewed. Results: Results show that the addition of hyperthermia to radiotherapy and/or chemotherapy for the treatment of breast cancer enhances treatment response and can increase local control. Conclusion: Further studies are required to evaluate potential benefits of hyperthermia in the treatment of other kinds of superficial tumors. © 2015 S. Karger GmbH, Freiburg. Source

Purpose. Abetalipoproteinemia is a very rare disease with multisystemic manifestations. Methods. Retrospective, case report. Results. We report a 9-year-old girl with a history of Bassen-Kornzweig syndrome diagnosed at the age of 3. The patient was referred to us by the pediatricians for ocular assessment. During the examination, an atypical pigmentary retinopathy and bilateral swelling of the optic discs were observed, with no consequences to her visual acuity. Conclusions. Ophthalmic manifestations in Bassen-Kornzweig syndrome are not uncommon. We describe, for the first time, bilateral swelling of the optic discs, a sign that appears directly associated with abetalipoproteinemia. © 2011 Wichtig Editore. Source

Purpose: To assess the progression of precancerous laryngeal lesions to squamous cell carcinoma (SCC), defined by specific histopathological criteria, in patients with long-term follow-up. Methods: Patients with laryngeal dysplasia, followed/treated between 1985 and 2008, were retrospectively evaluated and classified according to the World Health Organization classification system (WHO). The investigated outcome parameters were progression of dysplasia to SCC, time interval to malignant transformation and continuation of smoking as potential risk factors. Results: Fifty-nine patients were studied. Progression of dysplasia to SCC between the first and the final histological examination was statistically significant (p<0.0001). Malignant transformation appeared in 29 patients (49.2%). Serious dysplasia was more likely to progress to SCC (64.8%) compared to mild (41.7%) or moderate (44.4%) (p<0.0001). However, the time interval needed in these 29 cases to progress to cancer was not statistically related to the initial histological diagnosis. Continuation of smoking did not affect the progression of disease. However, the mean time from dysplasia to laryngeal cancer was much longer in patients who quitted smoking (33.5 months) vs those who continued smoking (19.5 months), with a marginal statistical difference (p=0.057). Conclusion: All patients with laryngeal dysplasia should be followed up at regular intervals. The progression of dysplasia to SCC did not seem to be directly related to the continuation of smoking or not. However, large long-term follow-up studies taking into account the degree of exposure (e.g. time of exposure, number of cigarettes) are needed in order to clarify risk factors and proper management. Consensus guidelines in diagnosis, follow-up, and treatment would improve substantially the current clinical practice. Source
