Learning curves are often referred to in the context of medical education and training, though their trajectories and natures are a matter of debate. The origins of this concept derive from industry and its relevance to contemporary medicine and surgery remains controversial. We describe the history, derivation, character and possible mechanisms to deal with the implications of learning curves in the current climate of clinical governance and modernising medical careers.

The aim of this study was to assess the information needs of patients diagnosed with oesophageal and gastric cancer and to compare these with their perceived information needs in the opinion of junior doctors. One hundred patients and 100 doctors responded to a questionnaire regarding the information needs of cancer patients. Seventy-nine per cent of patients wanted as much information as possible about their diagnosis, but only 35% of doctors were willing to give all the available information (P < 0.0001). Seventy-seven per cent of patients wanted to receive their diagnosis from a consultant whereas only 5% of doctors believed that patients should receive their diagnoses from a consultant (P < 0.0001). Eighty-four per cent of doctors were willing to communicate a serious illness with a good prognosis, yet only 43% would communicate a diagnosis with a poor prognosis (P < 0.0001). All 100 doctors had received formal training in breaking bad news, but 20 considered this inadequate. Socio-economic deprivation was associated with poor access to supplementary Internet derived information (P < 0.001). The majority of patients with a diagnosis of oesophagogastric cancer want a great deal of information regarding their illness, which contrasts with doctors' perceptions. Adequate training in information disclosure may help address this issue.

The aim of this study was to determine the role of body mass index (BMI) in a Western population on outcomes after esophagectomy for cancer. Two hundred and fifteen consecutive patients undergoing esophagectomy for esophageal cancer of any cell type were studied prospectively. Patients with BMIs > 25 kg/m were classified as overweight and compared with control patients with BMIs below these reference values. Ninety-seven patients (45%) had low or normal BMIs, 86 patients (40%) were overweight, and a further 32 (15%) were obese. High BMIs were associated with a higher incidence of adenocarcinoma versus squamous cell carcinoma (83%vs. 14%, P = 0.041). Operative morbidity and mortality were 53% and 3% in overweight patients compared with 49% (P = 0.489) and 8% (P = 0.123) in control patients. Cumulative survival at 5 years was 27% for overweight patients compared with 38% for control patients (P = 0.6896). In a multivariate analysis, age (hazard ratio [HR] 1.492, 95% CI 1.143-1.948, P = 0.003), T-stage (HR 1.459, 95% CI 1.028-2.071, P = 0.034), N-stage (HR 1.815, 95% CI 1.039-3.172, P = 0.036) and the number of lymph node metastases (HR 1.008, 95% CI 1.023-1.158, P = 0.008), were significantly and independently associated with durations of survival. High BMIs were not associated with increased operative risk, and long-term outcomes were similar after R0 esophagectomy.

Potentially curable gastrointestinal malignancy was diagnosed over 13 times more commonly using colonoscopy or barium enema vs. gastroscopy. For patients presenting with IDA, our findings favour investigating the lower GI tract first, or performing both gastroscopy and colonoscopy during the same endoscopy list.

Transthoracic esophagectomy (TT) has been championed as a better cancer operation than transhiatal esophagectomy (TH) because the approach facilitates meticulous wide tumor excision and lymphadenectomy. However, neoadjuvant chemoradiotherapy (CRTS) and chemotherapy (CS) have been reported to improve outcomes, and we aimed to compare outcomes after multimodal therapy related to the operative approach. One hundred and fifty-one consecutive patients were studied prospectively. All patients were staged with computed tomography and endoluminal ultrasound, and treatment decisions were related to stage and performance status. One hundred and nineteen TT (median age 58 years, 92 male, 54 CRTS, 65 CS) were performed compared to 32 TH (median age 57 year, 27 male, 14 CRTS, 18 CS). Primary outcome measure was survival. Post-operative morbidity and mortality were 54% and 4%, respectively, after TT compared with 59% and 6% after TH (chi2 0.239 df 1, P=0.625). Recurrent cancer was no less frequent after TT (52%) than after TH (37.5%, chi2 2.151 df=1, P=0.142). Cumulative uncorrected 5-year survival was 34% after TT compared with 53% after TH (log rank 1.44, df=1, P=0.2298). Median survival was also similar in lymph node positive patients (TT vs. TH, 23 months vs. 22 months, respectively, log rank 0.25, df=1, P=0.6199). Despite the fact that patients receiving multimodal therapy and a TH esophagectomy were less fit, operative morbidity, mortality and recurrence were similar, and survival did not differ significantly when compared with multimodal TT esophagectomy.
