- Dietary lignans, quercetin and resveratrol have oestrogenic properties, and animal studies suggest that they synergistically decrease cancer risk. A protective effect of lignans on the development of oesophageal cancer in humans has recently been demonstrated, and the present study aimed to test whether these three phytochemicals synergistically decrease the risk of oesophageal cancer. Data from a Swedish nationwide population-based case-control study that recruited 181 cases of oesophageal adenocarcinoma (OAC), 158 cases of oesophageal squamous-cell carcinoma (OSCC), 255 cases of gastro-oesophageal junctional adenocarcinoma (JAC) and 806 controls were analysed. Exposure data were collected through face-to-face interviews and questionnaires. The intake of lignans, quercetin and resveratrol was assessed using a sixty-three-item FFQ. Reduced-rank regression was used to assess a dietary pattern, and a simplified dietary pattern score was categorised into quintiles on the basis of the distribution among the control subjects. Unconditional multivariable logistic regression provided OR with 95 % CI, adjusted for all the potential risk factors. A dietary pattern rich in lignans, quercetin and resveratrol was mainly characterised by a high intake of tea, wine, lettuce, mixed vegetables, tomatoes, and whole-grain bread and a low intake of milk. There were dose-dependent associations between simplified dietary pattern scores and all types of oesophageal cancer (all P for trend < 0·05). On comparing the highest quintiles with the lowest, the adjusted OR were found to be 0·24 (95 % CI 0·12, 0·49) for OAC, 0·31 (95 % CI 0·15, 0·65) for OSCC, and 0·49 (95 % CI 0·28, 0·84) for JAC. The results of the present study indicate that a dietary pattern characterised by the intake of lignans, quercetin and resveratrol may play a protective role in the development of oesophageal cancer in the Swedish population.

- The strong male predominance in esophageal and gastroesophageal junctional adenocarcinoma remains unexplained. Sex hormonal influence has been suggested, but not proven. A protective role of dietary phytoestrogen lignans was hypothesized. A Swedish nationwide population-based case-control study was conducted in 1995-1997, including 181 cases of esophageal adenocarcinoma, 255 cases of gastroesophageal junctional adenocarcinoma, 158 cases of esophageal squamous cell carcinoma, and 806 control subjects. Data on various exposures, including dietary data, were collected through personal interviews and questionnaires. Dietary intake of lignans was assessed using a food frequency questionnaire and categorized into quartiles based on the consumption among the control participants. Unconditional logistic regression was used to calculate odds ratios (ORs) with 95 % confidence intervals (CIs), including adjustment for all established risk factors. Participants in the highest quartile of intake of lignans compared with the lowest quartile were at a decreased risk of esophageal adenocarcinoma (OR, 0.65; 95 % CI, 0.38-1.12; for trend =0.03), gastroesophageal junctional adenocarcinoma (OR, 0.37; 95 % CI, 0.23-0.58; for trend < 0.0001), and these adenocarcinomas combined (OR, 0.45; 95 % CI, 0.31-0.67; for trend < 0.0001). No clear associations were found between lignan intake and risk of esophageal squamous cell carcinoma. This population-based study indicates that a high dietary intake of lignans decreases the risk of adenocarcinoma of the esophagus and gastroesophageal junction.

- To assess quality of life (QoL) and symptoms after oesophageal cancer surgery, a prospective nationwide population-based study was conducted in 2001-2005, including most surgically treated oesophageal cancer patients in Sweden. Six months postoperatively patients responded to an EORTC quality of life core questionnaire (QLQ C-30) with an oesophageal-specific module (OES-18). Mean scores were calculated. Mann-Whitney test was used for group comparisons. Among 282 patients, QoL was considerably reduced compared to a reference general population (P < 0.001), and functioning scales were similarly negatively affected; particularly role (P < 0.001) and social (P < 0.001) functions. Younger patients scored worse than older. No gender differences were found. Dominating general symptoms included fatigue, appetite loss, diarrhoea, and dyspnoea, each significantly more pronounced than the general population (P < 0.001). Eating problems, cough, reflux, and oesophageal pain were common oesophageal-specific symptoms. Thus, patients who undergo oesophageal cancer resection suffer greatly from reduced QoL and several general and oesophageal-specific symptoms six months postoperatively. (c) 2006 Elsevier Ltd.

- The care pathway of patients with upper gastrointestinal cancers is complex. We retrospectively evaluated the patients' opinions of support and supportive care given by a specialist nurse who Led the care of such patients. A study-specific questionnaire addressed the support given by the specialist nurse and other professionals in the team before, during and after treatment. Virtually all 73 responders considered the support of the specialist nurse important (87-94%). This support seemed more appreciated than that of outpatient clinic (P = 0.00) and surgical ward staff (P = 0.01) during the diagnostic phase, and during the follow-up it became more important than that of all other team professionals. A second study-specific questionnaire assessed the supportive care. Of 49 patients, 71-94% completely agreed that the supportive care given by the specialist nurse was satisfactory, and 90-100% considered it important. Whereas 10% had difficulty in understanding physicians' information, none had such problems regarding information given by the nurse (P = 0.09). Review of documented contacts between the specialist nurse and 75 patients with oesophago-gastric cancer revealed that contacts were frequent during follow-up, and nutritional problems predominated. Thus, specialist nurses can be recommended as leaders of the care pathway of patients with upper gastrointestinal cancers. (c) 2006 Elsevier Ltd. All rights reserved.
