[Radical nature and life expectancy in the surgical treatment of esophageal and cardial carcinoma].

Fifty-four patients with carcinoma of the oesophagus and cardia were selected to have either a two-cavity radical operation or blunt oesophagectomy without thoracotomy. Squamous-cell carcinomas were randomized for postoperative radiotherapy or none. Neither the two-cavity radical operation nor additional radiotherapy prolonged life expectancy. The results cast doubt on the effectiveness of local radical or curative surgery for carcinoma of the oesophagus and cardia. The only objective in the choice of treatment must be to decrease operative mortality and to make the course of the disease tolerable to the patient.

Levodopa prolongs life expectancy and is non-toxic to substantia nigra.

The primary objective of the study was to determine the effect of levodopa (LD) on human substantia nigra. The study included patients seen at the Movement Disorder Clinic, Saskatoon over a 32 year period. The evidence provided is based on epidemiological observations of 934 consecutive Parkinson syndrome (PS) patients assessed during 22 years and detailed studies of six patients including two autopsies. Life expectancy increased significantly with LD therapy. The prolonged survival was evident when the patients were treated during early stage of the illness. One parkinsonian patient with substantia nigra (SN) pathology who was extensively studied for 30 years, revealed significant slowing of the disease progression while on LD. Three essential tremor patients who received 24 kg (26 years), 22 kg (21.5 years), and 8.5 kg (12.5 years) LD respectively, had no evidence of PS and one autopsy revealed normal SN. Two dopa-responsive dystonia patients who received LD 3 kg (11 years) and 17 kg (29 years) each had no evidence of PS and one autopsy revealed normal number of SN neurons. These observations indicate that LD is not toxic to human SN and are consistent with salutary effect of the drug on the SN in Parkinson's disease.

Long-term survival in 463 women treated with platinum analogs for advanced epithelial carcinoma of the ovary: life expectancy compared to women of an age-matched normal population.

The objective was to assess the long-term survival (5-15 years) in 463 women, with stages IIb-IV epithelial carcinoma of the ovary and to compare their survival with that of a normal population matched for age and sex. Statistical analysis of 463 women, with stages IIb-IV epithelial cancer of the ovary, who were participants in two consecutive North Thames Ovary Group randomized trials, which took place between 1985 and 1994, was performed. The median follow-up period was 10.5 years. The women were treated with debulking surgery, where possible, and adjuvant platinum chemotherapy. One of the randomized groups in the first North Thames trial also received total abdominal radiotherapy. Survival rates at 5, 10, and 15 years were assessed. Prognostic factors for long-term survival were determined using a mathematical model to separate early effects from late effects. The ratio of observed to expected deaths compared to the normal population was calculated. Overall survival at 5 years was 21% (95% confidence intervals 17.5-25%), at 10 years was 13.5% (95% confidence intervals 10.5-17%), and at 15 years was 12% (95% confidence intervals 9-16%). The important prognostic factors for long-term survival were disease-free or minimal residual disease (a single remaining deposit <2 cm) at initial surgery with tumor grade 1 and good performance status. Compared with the normal population (1995 data), the ratio of observed to expected deaths after start of chemotherapy at 5 years was 14.1 (P < 0.001 Fisher's exact test), at 9-10 years 4.9 (P = 0.0033, Fisher's exact test), while in the 11- to 15-year period it had dropped to 2.75 (P = 0.090, Fisher's exact test), which was not significantly different. Patients with advanced cancer of the ovary, who survive 11 years or longer, have a life expectancy which is very similar to that of a normal population of women of the same age. Women with advanced ovarian cancer have an improved chance of long-term survival following treatment if they present with minimal residual disease after primary surgical debulking, grade 1 tumors, and good performance status.
