Purpose We aimed to study patients with oral cancer, who received post-operative radiotherapy or chemoradiotherapy. Patients Ten patients (mean age 63.8 years) were included. Methods Oral mucositis, pain and xerostomia, maximum mouth opening (MMO) and functional abnormalities before and after RT were recorded. The 35 mm MMO or less was accepted as trismus. Patients completed the EORTC QLQ C-30 and Head/Neck35 questionnaires. Results Mean RT dose was 64.3 Gray. Six patients received chemoradiotherapy. Severe mucositis, pain and xerostomia were recorded in 6 and 5 patients respectively. MMO was reduced in all patients. The mean MMO (34 mm) reached the level of trismus. The total number of symptoms increased from 3.1 to 6.3 in C-30 and from 3.1 to 8.8 per patient in the H/N35. Severe fatigue, pain, limitations at work, weakness, sad feelings, family problems, sleeping problems, anorexia, financial difficulties, tense/irritable, constipation, nausea, vomiting and depression were most often reported with C-30. Most patients reported low to moderate quality of life. Severe oral, jaw and neck pain, swallowing problems, taste alterations, sticky saliva, dry mouth, coarseness, dental problems, feeling sick and reduced interest in life/sex were the most common symptoms reported with N/H35. Conclusions The observed trismus, 2- to 3-fold increase of symptoms and poorer quality of life highlighted the need for support of oral cancer patients, who receive postoperative radiotherapy or chemoradiotherapy.","PeriodicalId":38592,"journal":{"name":"Forum of Clinical Oncology","volume":"8 1","pages":"29 - 36"},"PeriodicalIF":0.0,"publicationDate":"2017-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1515/fco-2015-0023","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48350376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Overall survival (OS) and multivariate regression analyses were measured for all patients. Results 100 patients were included in this trial : 70 patients received postoperative RAI and 30 patients did not. The mean follow-up time was 7.1 (4.8 -15.1 years), and a median survival time could not be estimated. Overall survival at 10 years was 96% in the RAI vs 93% in the group without RAI (P < .001).

Not surprisingly, Btk is also implicated in the pathogenesis of B-cell lymphomas, like Chronic Lymphocytic Leukaemia/Small Lymphocytic Lymphoma (CLL/SLL), Mantle Cell Lymphoma (MCL) and Waldenström’s Macroglobulinemia (WM), which are driven by aberrant BCR signalling. Thus, targeting Btk represents a promising therapeutic strategy in the treatment of B-cell lymphoma patients. Ibrutinib, a selective Btk inhibitor, has already been approved as second-line treatment of CLL/SLL, MCL and WM patients, while more clinical studies of ibrutinib and novel Btk inhibitors are currently under way. In light of results of the RESONATE-2 trial, the approval of ibrutinib as a first-line treatment of CLL/SLL may well be approaching. Herein, we review Btk’s role in normal and malignant BCR signalling, as well as ibrutinib’s performance in B-cell lymphoma treatment and prognosis.","PeriodicalId":38592,"journal":{"name":"Forum of Clinical Oncology","volume":"8 1","pages":"14 - 7"},"PeriodicalIF":0.0,"publicationDate":"2017-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48968018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted this study to evaluate the cardiac safety of trastuzumab in clinical practice. Methods This study is a retrospective observational single institutional study conducted in the Oncology Center of King Abdulla Medical City (KAMC), Makkah, Saudi Arabia, from June 2011 to January 2014. We evaluated the incidence of cardio toxicity and associated risk factors during adjuvant trastuzumab treatment. Results Of 57 patients, 20 patients (35%) exhibited cardiotoxicity. About 14% of patients had drop of left ventricular ejection fraction (LVEF) below 50%, whilst 10% and 15% drop of LVEF below their baseline levels were found in 30% and 5% of patients, respectively. About 98.3% of our patients have completed treatment, of whom 21% had a provisional interruption because of a fall in LVEF. A definitive trastuzumab discontinuation has been made in 1.75% of cases because of a nonregressive reduction in LVEF. Analysis of risk factors related to trastuzumab cardio toxicity found that patients older than 40 years were more likely to develop cardio toxicity compared to those younger than 40 years. This difference was statistically significant (p = 0.042). Conclusion In our study, the cardiac safety seems comparable with the literature data. Trastuzumab-related cardiotoxicity is manifested by an asymptomatic decrease in the LVEF and less commonly by clinical heart failure. Most instances are transient, asymptomatic and reversible.","PeriodicalId":38592,"journal":{"name":"Forum of Clinical Oncology","volume":"7 1","pages":"1 - 6"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67375204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A lot of epidemiological and clinical evidence suggests that the metabolic syndrome is linked not only to cardiovascular diseases and diabetes mellitus type 2 but also to cancer development and progression. In this review the potential mechanisms tying the metabolic syndrome with cancer are presented. The role of insulin resistance and hyperinsulinemia, the activation of insulin-like growth factor-1 (IGF-1) pathway, and the induction of cytotoxic products are highlighted. Subsequent effects leading to oxidative stress, release of lipokines with signaling properties by adipocytes, development of a sustained systemic inflammation, production of inflammatory cytokines, and establishment of a tumorigenic environment are also discussed. The importance of the metabolic syndrome and obesity coupled with the deeper understanding of the underlying molecular mechanisms has trigger intensive clinical research with an aim to prevent the risk of cancer and improve outcomes.

The carriers of these mutations are at high risk for breast and ovarian cancers and increased risk for pancreatic and prostate cancers. Personal and family history are routinely used to identify individuals at risk for carrying such mutations. Genetic counselling is required to guide them through genetic testing and risk management. Positive testing corresponds to a deleterious mutation, whereas negative testing is considered as uninformative; variants of unknown clinical significance are also classified as uninformative. The most effective risk reduction strategy involves bilateral prophylactic mastectomy and bilateral salpingo-oophorectomy, eliminating 90% of breast and 97% of ovarian cancer risks, respectively. Before and until such surgery, surveillance with physical examination, mammography and magnetic resonance mammography, starting at 25–30 years of age, are recommended for the early diagnosis of breast cancer; semi-annual surveillance with physical examination, transvaginal ultrasound and serum CA-125 is recommended for women who have not had prophylactic surgery. Carriers diagnosed with breast cancer run a high risk for a new breast primary and this information should be used accordingly. PARP inhibitors is a new class of antineoplastic agents, already approved for advanced BRCA1/2 mutant (germline or somatic) ovarian cancer. Multigene panel testing may follow a negative BRCA genetic test, often identifying other genetic causes of cancer, expanding its role in oncology. Further adoption of PARP inhibitors, refinement in estimation of BRCA-associated cancer risks and wider population testing, through NGS technology, may become available in the near future.","PeriodicalId":38592,"journal":{"name":"Forum of Clinical Oncology","volume":"7 1","pages":"16 - 24"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67375178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
