The use of clinical guidelines for referral of patients with lesions suspicious for oral cancer may ease early diagnosis and improve education of hea…
2010
UNLABELLED Early diagnosis and referral of oral cancer is essential. Successful implementation of clinical guidelines must include current practitioners and students. OBJECTIVE To evaluate the diagnostic accuracy of students at oral cancer screening and to assess the effectiveness of clinical referral guidelines. STUDY DESIGN Fifth year dental students were randomly allocated to either control (n=19) or experimental groups (n = 18). Both received the customary training in oral diagnosis. The experimental group underwent a 2 hour workshop where the guidelines for the referral of suspicious lesions were discussed. Three months later, a set of 51 clinical cases including benign, malignant, and…
Oral potentially malignant disorders: is malignant transformation predictable and preventable?
2014
Leukoplakia is the most common potentially malignant disorder of the oral mucosa. The prevalence is approximately 1% while the annual malignant transformation ranges from 2% to 3%. At present, there are no reliable clinicopathological or molecular predicting factors of malignant transformation that can be used in an individual patient and such event can not truly be prevented. Furthermore, follow-up programs are of questionable value in this respect. Cessation of smoking habits may result in regression or even disappearance of the leukoplakia and will diminish the risk of cancer development either at the site of the leukoplakia or elsewhere in the mouth or the upper aerodigestive tract. The…
Analysis of cardiac and pulmonary complication probabilities after radiation therapy for patients with early-stage breast cancer
2009
Objective. The purpose of this study was to evaluate the radiobiological implications of clinical use of respiratory-gated techniques for postoperative radiation therapy of early-stage left-sided breast cancer after breast-conserving surgery. Material and methods. Radiation therapy treatment plans of 80 patients with early-stage breast cancer (stage I–II), receiving whole breast irradiation after breast-conserving therapy, were analyzed. The control group consisting of 47 patients received standard radiation therapy, and the respiratory-gated group consisting of 33 patients received deep inspiration-gated radiation therapy. Normal tissue complication probabilities (NTCP) for cardiac mortali…
Stauffer’s Syndrome in Patient with Metastatic Prostate Cancer
2019
Cholestasis is a symptom that can be present in many conditions, such as bile duct obstruction by malignant mases, obstruction by gallstone, acute and chronic viral hepatitis, and autoimmune disorders, such as primary biliary and sclerosing cholangitis. Stauffer syndrome is a rare type of paraneoplastic syndrome that presents as cholestasis with absence of underlying disease. Classically Stauffer syndrome has been described in renal cell cancer patients. In literature cholestasis as manifestation of paraneoplastic syndrome has also been described in patients with prostate adenocarcinoma and pancreatic and bronchogenic carcinoma. Conclusions. Stauffer syndrome should be kept in mind in patie…
Screening for colorectal cancer with immunochemical faecal occult blood tests.
2012
Population-based studies have shown that guaiac faecal occult blood testing followed by colonoscopy in case of positivity can reduce colorectal cancer mortality. However these tests have been criticised for their fairly low sensitivity. For this reason attention has been given to alternative tests. The aim of this paper is to review the evidence for screening for colorectal cancer using qualitative immunochemical faecal occult blood tests. For the complete range of tested cut-off values, immunochemical faecal occult blood tests lead to higher diagnostic yield, improved sensitivity and greater participation. The optimal number of samples and the optimal cut-off value has to suit local resour…
Treatment strategies for cancer patients with breakthrough pain.
2009
Breakthrough pain (BTP) is a transitory flare of pain superimposed on an otherwise stable pain pattern in patients treated with opioids. It is normally severe in intensity, has a rapid onset, has a variable duration (on average 30 min) and is considered a negative prognostic factor. OBJECTIVE: To verify the data in the literature about therapy strategies for BTP in cancer patients. METHODS: To find clinical trials investigating drug therapy for BTP. CONCLUSION: The treatment of BTP in cancer patients receiving opioids is principally based on the use of opioids, preferentially with a short onset. Fentanyl delivered by recently developed systems seems to be the best option to cover the tempor…
Expression pattern of receptor activator of NFκB (RANK) in a series of primary solid tumors and related bone metastases.
2011
Receptor activator of NFκB ligand (RANKL), RANK, and osteoprotegerin (OPG) represent the key regulators of bone metabolism both in normal and pathological conditions, including bone metastases. To our knowledge, no previous studies investigated and compared RANK expression in primary tumors and in bone metastases from the same patient. We retrospectively examined RANK expression by immunohistochemistry in 74 bone metastases tissues from solid tumors, mostly breast, colorectal, renal, lung, and prostate cancer. For 40 cases, tissue from the corresponding primary tumor was also analyzed. Sixty-six (89%) of the 74 bone metastases were RANK-positive and, among these, 40 (59.5%) showed more than…
Adherence, compliance and persistence to oral antineoplastic therapy: a review focused on chemotherapeutic and biologic agents
2011
Introduction: To date, orally administered chemotherapy and biologic agents represent a significant percentage of all antineoplastic treatments in several types of cancer, which are most likely to increase in the near future. In this scenario, the issue of adherence and persistence to oral therapy is a key issue since poor compliance to oral antineoplastic treatments may negatively influence patients' clinical outcomes and, in turn, cause an increase in costs, number of hospitalizations and time spent in the hospital. Areas covered: The issue of adherence to new oral chemotherapeutic and/or biologic agents has not been deeply evaluated and data published in medical literature are quite scar…
Social disparities, health risk behaviors, and cancer
2013
Background: Overall cancer incidence rates decreased in the most recent time period in both men and women, largely due to improvements in surgical therapeutic approaches (tertiary prevention) and screening programs (secondary prevention), but differences in cancer incidence and survival according to socioeconomic status are documented worldwide. Health risk behaviors, defined as habits or practices that increase an individual’s likelihood of harmful health outcomes, are thought to mediate such inequalities. Discussion: Obesity has been related with increased cancer incidence and mortality due to imbalance of leptin and adiponectin which are connected to activation of PI3K, MAPK, and STAT3 p…
Duodenal Signet Ring Cell Carcinoma in a Celiac Patient
2009
Celiac disease results from damage to the small intestinal mucosa due to an inappropriate immune response to a cereal protein. Long-standing or ‘refractory’ celiac disease is associated with an increased risk of autoimmunity and malignancy. We produced a brief literature review starting from a case of duodenal cancer in a celiac patient. The patient with an history of celiac disease since six months presented with acute manifestation of gastric outlet syndrome. A duodenal stricture was diagnosed at upper gastrointestinal endoscopy and confirmed by abdominal computed tomography. He was successfully treated by segmental duodenal resection. In the resected specimens, the diagnosis was duodenal…
