Case-control studies and short term prospective studies have suggested that selected groups of patients with precursors of colorectal cancer may benefit from colonoscopic surveillance after initial removal of adenomas. The aim of the present study was to demonstrate such a possible benefit from long term (1-24 years) colonoscopic surveillance in a population of patients with all types of adenomas regardless of size and way of removal. Two thousand and forty-one patients with a first time diagnosis of colorectal adenoma were included in prospective surveillance between year 1978 and 2002. ⋯ A total of 6 289 colonoscopies resulted in severe complications in 20 patients and two died from complications. Long-term colonoscopic surveillance may reduce incidence of CRC as well as mortality in patients with sporadic adenomas. The benefit is reduced to a minor degree by complications from surveillance.

Seminal advances in early detection of and treatment strategies for cancer have led to burgeoning numbers of cancer survivors. While most therapeutic modalities for cancer are beneficial and lifesaving, they are associated with adverse long-term and late sequelae. ⋯ Adverse sequelae contribute to burden of illness, health care costs, and decreased length and quality of survival. To-date, very few studies have compared survivor outcomes pre-and post diagnosis. It is critical to examine under-researched questions and understudied survivor groups. Regular follow-up care and monitoring of health status post cancer treatment should 1) permit the timely diagnosis and treatment of adverse outcomes; 2) enable timely diagnosis and treatment of recurrences; 3) facilitate screening and early detection of second cancer(s); 4) allow for detection and management of co-morbidities; and 5) provide the opportunity for preventive strategies such as lifestyle changes. Research findings to-date underscore the need for continued cancer survivorship research that will: inform our understanding of the mechanisms underlying adverse sequelae; lead to the design of less toxic treatments; test the effectiveness of interventions - medical, pharmacologic, and behavioral - that reduce adverse outcomes; test models of post-treatment follow-up care; develop an evidence base for optimal follow-up care practices; and inform survivor and provider decision making.

Cancer rehabilitation programs mainly involve endurance training, and little attention is paid to strength training. Cancer survivors are generally advised to train at much lower workloads than the standard guidelines for strength training suggest. The purpose of this study is to evaluate the effectiveness of an 18-week high-intensity strength training program in cancer survivors. ⋯ We conclude that a supervised, high-intensity strength training program seems to be an effective means to improve muscle strength, cardiopulmonary function, and HRQOL and should be incorporated in cancer rehabilitation programs. Further randomized trials are needed to confirm the results.

Widespread acceptance of breast conserving surgery for early breast cancer has led to renewed interest in multifocality, which is seen in 13-63% of breast cancers. According to current guidelines, oestrogen/progesterone receptor status is assessed on the sample obtained at initial core biopsy or the main tumour focus in multifocal breast cancer (more than one distinct tumour focus in a quadrant). We assessed receptor status of individual foci in multifocal breast cancer. ⋯ Sixteen patients (88%) were oestrogen receptor-positive. Progesterone receptor staining showed more variability between foci in two patients but, since the tumours were oestrogen receptor-positive this would not have affected clinical decision-making. No major differences in oestrogen receptor status between multiple tumour foci in the same quadrant were found in this pilot study.

Addition of thoracic radiation therapy (TRT) to chemotherapy (CHT) can increase overall survival in patients with small cell lung cancer limited-disease (SCLC-LD). Accelerated fractionation and early concurrent platinum-based CHT, in combination with prophylactic cranial irradiation, represent up-front treatment for this group of patients. Optimised and tailored local and systemic treatment is important. ⋯ Medica survival was 20.8 months with no significant difference between the two groups. In conclusion, TRT with a total dose of 60 to 45 Gy is feasible with comparable toxicity and no difference in local control or survival. Distant metastasis is the main cause of death in this disease; the future challenge is thus further improvement of the systemic therapy combines with optimised local TRT.
