SummaryAim: We aimed to document the prevalence of misunderstanding in cancer patients and investigate whether patient denial is related to misunderstanding.Patients and methods: Two hundred forty-four adult cancer outpatients receiving treatment completed a survey assessing levels of understanding and denial. Doctors provided the facts against which patient responses were compared. Multiple logistic regression analyses determined the predictors of misunderstanding.Results: Most patients understood the extent of their disease (71%, 95% CI: 65%-77%) and goal of treatment (60%, 95% CI: 54%-67%). Few correctly estimated the likelihood of treatment achieving cure (18%, 95% CI: 13%-23%), prolongation of life (13%, 95% CI: 8%-17%) and palliation (18%, 95% CI: 10%-27%). Patient denial predicted misunderstanding of the probability that treatment would cure disease when controlling for other patient and disease variables (OR = 2.20, 95% CI: 0.99-4.88, P = 0.05). Patient ratings of the clarity of information received were also predictive of patient understanding.Conclusions:Patient denial appears to produce misunderstanding, however, doctors' ability to communicate effectively is also implicated. The challenge that oncologists face is how to communicate information in a manner which is both responsive to patients' emotional status and sufficiently informative to allow informed decision-making to take place.

Seventy-four patients who underwent seton treatment of high anal fistulae over a 6-year period have been reviewed. Four different techniques were used: staged fistulotomy (n = 24), cutting seton (n = 13), short-term seton drainage (n = 14) and long-term seton drainage in patients with Crohn's disease (n = 23). Recurrence developed in two patients (8 per cent) undergoing two-stage fistulotomy; two patients (14 per cent) undergoing short-term drainage and nine (39 per cent) of the patients with Crohn's disease. Three patients with Crohn's disease required proctectomy for progressive perianal disease. The remaining 11 patients with Crohn's disease (48 per cent) obtained a good result. None of the patients treated with a cutting seton developed a recurrence. Minor incontinence developed in 13 patients (54 per cent) undergoing two-stage fistulotomy and seven patients (54 per cent) treated with a cutting seton. When sphincter muscle was not divided, five patients (36 per cent) undergoing short-term drainage and six patients (26 per cent) undergoing long-term drainage developed minor incontinence. High complex fistulae can be successfully treated with only minor loss of continence using different seton techniques. In high Crohn's fistulae, long-term seton drainage preserves sphincter function, but recurrence is common if the seton is removed.

The clinical and histologic features of 476 tumors fitting the 1995 FIGO definition of stage IA cervical cancer, treated at a Sydney tertiary referral hospital between 1953 and 1992, are reviewed. Five-year follow-up was complete with a median of 10 years. The diagnosis was increasingly made by histologic examination of colposcopically directed cone biopsy. The majority (88%) of tumors were squamous. The proportion of both younger women (3 mm. Treatment was surgical in 99% and was increasingly more conservative as the study progressed with no apparent increase in treatment failure. From 1973 treatment by cone biopsy rose from 6.5 to 35%, by radical hysterectomy fell from 51 to 21% and by lymphadenectomy from 53 to 26%. Only one of 115 patients treated by cone biopsy died. Positive lymph nodes were detected in 1.7% of 180 patients undergoing lymphadenectomy. There were 16 recurrences (3.4%); six vaginal with no cancer deaths, nine pelvic and one distant, with nine deaths and three new cancers (two deaths). Univariate analysis suggests that older age, glandular tumors and those invading 3 mm were associated with more treatment failures and multivariate analysis showed that both conservative hysterectomy and the omission of lymphadenectomy are associated with higher recurrence rates with >3 mm invasion. The study failed to resolve the dilemma of predicting those tumors with a poor prognosis.
