We report the results of a multicentre retrospective chart review of 2214 patients with thyroid cancer registered at 13 radiotherapy centres between 1958 and 1978. The data analysed included sex, age at the time of diagnosis, pathological diagnosis, extent of disease before treatment, types of treatment and their complications, and the rates of recurrence and survival up to 24 years after diagnosis. Although papillary cancers were most common, anaplastic and miscellaneous tumours were more frequent than expected, which reflects the type of patients referred by endocrinologists and surgeons to radiotherapy centres. There were marked differences in patterns of referral to the centres. Some patients with papillary and follicular thyroid cancers died of these cancers up to 20 years after diagnosis. The clinical manifestations, treatment and outcome of the rarer types of thyroid malignant tumours were of particular interest. The influence of age at the time of diagnosis on survival rates for patients with papillary or follicular thyroid cancer was highly significant, indicating much more aggressive behaviour of these cancers in older patients, particularly those beyond the age of 60 years. A more detailed analysis of tumour subtypes should provide new information on their natural history and lead to better management.

Patient with goiter usually has benign disease. While investigation is important, clinical factors weight heavily in the diagnosis of cancer. Aside from serum calcitonin and CEA, biochemical findings are of little help. Radioisotope scanning is of fundamental importance and has an implication in history. Ultrasonography has a diminishing role although its use has led to the widespread acceptance of needle aspiration. Needle aspiration cytology is now the most important maneuver in preoperative assessment and management of the goiter patient. Its results permit refined operative selection, the institution of safe conservative management, and greater organization in surgical treatment. Persistent cooperation between clinician and pathologist can yield a high rate of the reliable preoperative cytological diagnosis obtained by needle aspiration.

The biology of colorectal cancer provides a unique opportunity for early detection and prevention. There is now evidence that screening of asymptomatic average-risk individuals over 50 years of age can reduce mortality resulting from colorectal cancer. New recommendations from the US Preventive Services Task Force endorse screening with fecal occult blood tests or sigmoidoscopy. The best method for population screening remains uncertain. The cost of screening is an important issue in the development of public policy. This review discusses the various screening options, examines the "downstream" effects of screening, and reviews the anticipated costs and effectiveness. Ultimately, the effectiveness of any screening program depends on patient compliance. Further research is needed to determine the best methods of enhancing patient adherence to a screening program.

Accurate tumor staging is essential for choosing the appropriate treatment strategy in patients with lung cancer. It has already been shown that FDG-PET is highly accurate in classifying lung nodules as benign or malignant. Integrated PET-CT enables the exact matching of focal abnormalities on PET to anatomic structures on CT. PET-CT is superior in diagnostic accuracy for T staging and differentiation between tumor and peritumoral atelectasis. PET has also proved to be a very effective staging modality for mediastinal nodal staging. It has been demonstrated to assist mediastinoscopy to reveal additional mediastinal disease in 6% of patients. PET detects unexpected extrathoracic metastases in 10-20% of patients and changes therapeutic management in about 20% of patients. A very high accuracy of FDG-PET in distinguishing recurrent disease from benign treatment effects has been shown. Patients should be evaluated after a minimum of 2 months after completion of therapy. FDG-PET can be clinically used for selecting biopsy sites. At our institution PET-CT has become the standard imaging modality for staging patients with lung cancer. Although not all tumors take up FDG, other radiotracers are being studied to expand the utility of PET-CT. PET-CT offers many opportunities for the patients, the clinicians, and the researchers. PET-CT has the potential to become the most efficient oncologic examination in the near future.

Calcitriol, 1 , 25-dihydroxyvitamin D3 (1,25 (OH)2D3), the most active form of vitamin D, is a pleotropic hormone with a wide range of biological activities. Due to its ability to regulate calcium and phosphate metabolism, 1,25D3 plays a major role in bone health. In addition, 1,25D3 binds to the vitamin D receptor and thereby regulates the expression of a number of genes which control growth, differentiation and survival of cancer cells. In agreement, the levels of vitamin D3 appear to be an essential determinant for the development and progression of colon cancer and supplementation with vitamin D3 is effective in suppressing intestinal tumorigenesis in animal models. Vitamin D3 has been estimated to lower the incidence of colorectal cancer by 50%, which is consistent with the inverse correlation between dietary vitamin D3 intake or sunlight exposure and human colorectal cancer. Several studies confirmed that increasing vitamin D3 lowers colon cancer incidence, reduces polyp recurrence, and that sufficient levels of vitamin D3 are associated with better overall survival of colon cancer patients. Vitamin D regulates the homeostasis of intestinal epithelium by modulating the oncogenic Wnt signaling pathway and by inhibiting tumor-promoting inflammation. Both activities contribute to the ability of 1,25D3 to prevent the development and progression of colon cancer.

Mouse models of colorectal cancer (CRC) have been crucial in the identification of the role of genes responsible for the full range of pathology of the human disease and have proved to be dependable for testing anti-cancer drugs. Recent research points toward the relevance of tumor, angiogenic, and immune microenvironments in CRC progression to late-stage disease, as well as the treatment of it. This study examines important mouse models in CRC, discussing inherent strengths and weaknesses disclosed during their construction. It endeavors to provide both a synopsis of previous work covering how investigators have defined various models and to evaluate critically how researchers are most likely to use them in the future. Accumulated evidence regarding the metastatic process and the hope of using checkpoint inhibitors and immunological inhibitor therapies points to the need for a genetically engineered mouse model that is both immunocompetent and autochthonous.

Inhibition of specific processes essential for tumour vascular development is actually one of the key strategies for treatment of lung cancer, for which angiogenesis is consistently predictive of a poor prognosis. The most promising agents target the vascular endothelial growth factor (VEGF) pathway, either by preventing VEGF-receptor binding as bevacizumab or inhibiting downstream receptor signaling in endothelial cells. Combination of bevacizumab with standard first-line chemotherapy in non-small cell lung cancer demonstrates a significant survival advantage comparing to chemotherapy alone, which provides the "proof of concept" for inhibition of angiogenesis in lung cancer. Development of small molecules inhibiting tyrosine kinase activity of VEGF-receptors is ongoing; many of them showed a single-agent activity but their most likely use will be in combination with chemotherapy or biological agents. Toxicity issues are of concern with the occurrence of fatal pulmonary hemorrhage after cavitation and necrosis of primary tumour, which requires appropriate selection of patients before treatment. A better understanding of the complex process of angiogenesis and of surrogate markers of treatment effect will improve our ability to design more effective therapies.

Households are becoming increasingly heterogeneous. While previous studies have revealed many important insights (e.g., wealth effect, income effect), they could only incorporate two or three variables at a time. However, in order to have a more detailed understanding of complex household heterogeneity, more variables should be considered simultaneously. In this study, we argue that advanced clustering techniques can be useful for investigating high-dimensional household heterogeneity. A deep learning-based clustering method is used to effectively handle the high-dimensional balance sheet data of approximately 50,000 households. The employment of appropriate dimension-reduction techniques is the key to incorporate the full joint distribution of high-dimensional data in the clustering step. Our study suggests that various variables should be used together to explain household heterogeneity. Asset variables are found to be crucial for understanding heterogeneity within wealthy households, while debt variables are more important for those households that are not wealthy. In addition, relationships with sociodemographic variables (e.g., age, education, and family size) were further analyzed. Although clusters are found only based on financial variables, they are shown to be closely related to most sociodemographic variables.

Radioiodine therapy is indicated in patients after total thyroidectomy for differentiated thyroid cancer, either as ablation of remnant thyroid tissue or to treat distant metastasis, most commonly to lung and bone. Surveillance after treatment includes thyroglobulin measurement, neck ultrasonography, chest CT, scintigraphy with radiothallium or diagnostic dose radioiodine, and possibly FDG-PET. Minor but frequent side effects involve organs with physiological iodine uptake, namely the salivary glands and stomach. Uncommon but serious ones are aggravation of spinal paralysis in cases with large vertebral metastasis and myelosuppression in those with extensive skeletal lesions. Despite clear therapeutic effects in some subjects, proving prolonged survival with this therapy in the group of patients with known metastasis as a whole is an elusive goal due to too good prognosis. One the other hand, a prospective analysis of a large case series did show beneficial effect of the radio-ablation. Empirical treatment is still debatable in subjects with elevated serum thyroglobulin level and negative whole body radioiodine scan. In the near future recombinant human TSH will obviate the need for intentional hypothyroidism in preparation for diagnostic scan and therapy with radioiodine.

TGFbeta and activin are members of the TGFbeta superfamily and play a wide role in development, proliferation and apoptosis. These growth factors exert their biological effects by binding to the type I and II membrane receptors to transduce their signalling through the nucleus by phosphorylation of R-SMADs (SMAD 2/3) and co-SMADs (Smad 4). The proper control of TGFbeta/activin pathway is negatively regulated by inhibitory SMAD (SMAD7) and by E3 ubiquitination enzymes (Smurfs). Physiologically, TGFbeta and activin act as potent growth inhibitors in thyroid follicular cell. Thus, alterations in the receptors and components of SMAD signalling pathway are associated with several types of tumors. Since TGFbeta and activin generate their intracellular signalling through the same components of the SMAD pathway, the unbalance of this pathway impairs both of anti-mitogenic signals in the cell. This review addresses aspects of the molecular mechanisms in the understanding of resistance to the growth inhibitory effects of TGFbeta and activin due to the disequilibrium in the SMAD inhibitory pathway in thyroid neoplasia.

Thyroid cancer is comparatively rare. Thyroid nodules, on the other hand, are frequently diagnosed as a result of increasing use of diagnostic imaging. Cytological investigation of small nodules that have been found by chance often reveals micropapillary carcinoma that is probably not clinically relevant. The new guideline 'Thyroid cancer' advises that cytological investigation of these non-palpable, incidentally discovered thyroid nodules should only be performed on indication. The standard treatment for patients with papillary or follicular thyroid cancer consists of thyroidectomy followed by, if indicated, lymph-node dissection, ablation therapy with radioactive iodine and TSH-suppression. The extent of this treatment is determined on the basis of known prognostic factors and the results of initial treatment. Targeted systemic therapy is available for patients with metastatic progressive disease. There is more focus on the effects of short- and long-term treatment, in order to optimise quality of life.

Nox1 mRNA, protein, and activities were compared in the paired primary and metastatic colon adenocarcinoma cell lines SW480 and SW620, and in normal colon tissues and colon cancer tissues. Our results demonstrated that Nox1 levels were higher in the primary SW480 cells than that in metastatic SW620 cells and were not associated with colon cancer progression. We further discovered that vinculin protein level in SW620 was much higher than that in SW480 cells, whereas E-cadherin was lower. We conclude that vinculin and E-cadherin, but not Nox1, may serve as biomarkers for colon cancer progression.

In colon cancer, the occurrence of metastases is associated with microsatellite stability. As metastatic cells derive from a clonal expansion of primary tumor cells, specific genomic alterations are expected in addition to the common genomic profile.

Incidence and mortality attributed to lung cancer has risen steadily since the 1930s. Efforts to improve outcomes have not only led to a greater understanding of the etiology of lung cancer, but also the histologic and molecular characteristics of individual lung tumors. This article describes this evolution by discussing the extent of the current lung cancer epidemic including contemporary incidence and mortality trends, the risk factors for development of lung cancer, and details of promising molecular targets for treatment.

The results of the many clinical trials published in 1997 had only modest impact on the treatment results using either cytostatic agents alone or combined with radiotherapy in lung cancer. In SCLC, combination chemotherapy including platin-compounds (cisplatin, carboplatin) and the podophyllotoxins (etoposide and teniposide) continue to be the cornerstone of therapy. Complete plus partial responses to combination chemotherapy occurs in 80-90% of all patients. Median survival is at present 11-17 months, and overall 5-year survival approximately 5% depending on the initial tumor stage. The duration of treatment has been shortened to 5-6 months. In relapsing patients topotecan and paclitaxel appear to have clinical useful activity. For epidermoid, adeno- and large cell carcinoma further support has arisen for the use of preoperative and preirradiatory chemotherapy in stage III NSCLC, but further studies are needed before specific recommendations can be given for general use. For patients with advanced NSCLC, new innovative treatments are still urgently needed. Platin-containing regimens with the inclusion of new agents, such as gemcitabine, taxenes, and navelbine, yielded response rates of 42-55% in phase II trials, but results from large phase III trials are necessary in order to measure the impact of these new agents in the management of NSCLC. Major improvements of therapy for mesothelioma have not occurred within the last year.

Cervical lymph node metastases are present in a considerable number of patients with differentiated and medullary thyroid cancer. The completeness of surgical resection, including clinically significant lymph node metastases, is an important determinant of outcome, because cervical lymph nodes represent the most common site of persistent and recurrent disease. This article delineates the management of nodal disease in thyroid cancer, focusing on the preoperative evaluation, operative management, and postoperative assessment of cervical lymph nodes.

Lung cancer remains a major worldwide health problem, accounting for more than a sixth of cancer deaths. The proportion of cancers that are adenocarcinomas is increasing in North America and to some degree in Europe, leading to a changing clinical picture characterised by early development of metastases. Newer diagnostic techniques have allowed for more accurate tumour staging and treatment planning. In patients with non-small-cell cancer, surgical resection offers substantial cure rates in early-stage cases. Combined chemotherapy plus radiation therapy has clearly improved the treatment results for patients with locally advanced cancers, and patients with metastatic disease are now candidates for newer chemotherapy regimens with more favourable results than in the past. Small-cell lung cancer is highly responsive to chemotherapy, and recent advances in radiation therapy have improved the prospects for long survival. New techniques for screening, and innovative approaches to both local and systemic treatment offer hope for substantial progress against this disease in the near future.

Over the last 50 years, the incidence of human thyroid cancer disease has seen a significative increment. This comes along with an even higher increment of surgery, since, according to the international guidelines, patients are sometimes addressed to surgery also when the fine needle aspiration gives undetermined cytological diagnosis. As a matter of fact, only 30% of the thyroid glands removed for diagnostic purpose have a post surgical histological report of malignancy: this implies that about 70% of the patients have suffered an unnecessary thyroid removal. Here we show that Raman spectroscopy investigation of thyroid tissues provides reliable cancer diagnosis. Healthy tissues are consistently distinguished from cancerous ones with an accuracy of [Formula: see text] 90%, and the three cancer typology with highest incidence are clearly identified. More importantly, Raman investigation has evidenced alterations suggesting an early stage of transition of adenoma tissues into cancerous ones. These results suggest that Raman spectroscopy may overcome the limits of current diagnostic tools.

The complete response rate in advanced non-small cell lung cancer is extremely low and the effect of chemotherapy on survival is still obscure. The emergence of resistance to anticancer agents results in the poor prognosis in small cell lung cancer although the initial response rate has improved. The significance of chemosensitivity test in lung cancer can be classified to three areas. The first of these as the individualization of chemotherapy, which means the selection of different active drugs for individual patients. In spite of numerous studies, there remain many theoretical and technical problems in predictive drug sensitivity testing. It is still far from practical use. Secondly, drug sensitivity tests have contributed to the screening of new anticancer agents. Since 1986, NCI (USA) started the disease oriented drug screening system (DOS) using human cancer cell lines. So far, active drugs against drug resistant tumors such as colon and non-small cell carcinoma have been found out by DOS. The clinical application of these drugs selected by DOS may give the answer concerning the validity of this new screening system. Thirdly, drug sensitivity tests have widely been used for the analysis of the mechanisms of drug sensitivity and resistance. By the progress of study in this field the biochemical and molecular biological targets of drug sensitivity test will be elucidated.

Evidence has now accumulated that colonoscopy and removal of polyps, especially during screening and surveillance programs, is effective in overall risk reduction for colon cancer. After resection of malignant pedunculated colon polyps or early stage colon cancers, long-term repeated surveillance programs can also lead to detection and removal of asymptomatic high risk advanced adenomas and new early stage metachronous cancers. Early stage colon cancer can be defined as disease that appears to have been completely resected with no subsequent evidence of involvement of adjacent organs, lymph nodes or distant sites. This differs from the clinical setting of an apparent "curative" resection later pathologically upstaged following detection of malignant cells extending into adjacent organs, peritoneum, lymph nodes or other distant sites, including liver. This highly selected early stage colon cancer group remains at high risk for subsequent colon polyps and metachronous colon cancer. Precise staging is important, not only for assessing the need for adjuvant chemotherapy, but also for patient selection for continued surveillance. With advanced stages of colon cancer and a more guarded outlook, repeated surveillance should be limited. In future, novel imaging technologies (e.g., confocal endomicroscopy), coupled with increased pathological recognition of high risk markers for lymph node involvement (e.g., "tumor budding") should lead to improved staging and clinical care.

Similarly to other malignancies, immune checkpoint inhibitor therapy is a revolutionary, effective new treatment possibility for lung cancer. In lung cancer carcinogenesis is related mainly to tobacco smoking with high somatic mutation rate and immunogenicity. The PD-1 inhibitor nivolumab and pembrolizumab and the PD-L1 inhibitor atezolizumab is a labelled indication in second line setting in advanced nonsmall cell lung cancer (NSCLC). Avelumab and durvalumab have promising activity as well. Based on the data of KEYNOTE 024 trial, pembrolizumab is approved in first line setting for cases with 50% PD-L1 expression. In this selected patient population, progression-free survival has doubled, and overall survival was significantly better in pembrolizumab-treated patients compared to those receiving standard of care. Pembrolizumab treatment became a new first line standard of care in advanced NSCLC. There are numerous ongoing clinical trials in lung cancer with immune checkpoint inhibitors in combination with cytotoxic chemotherapy, targeted agents, or in adjuvant setting.
