BACKGROUND EORTC trial 22921 examined the addition of preoperative or postoperative chemotherapy to preoperative radiotherapy in patients with rectal cancer. After a median follow-up of 5 years, chemotherapy-irrespective of timing-significantly improved local control. Adjuvant chemotherapy did not improve survival, but the Kaplan-Meier curves diverged,(More)
Having found, in the same medical centre, an abnormally high (15%) frequency of bone metastases from colorectal carcinoma, the authors report a series of 8 cases and review what is now known of this reputed rare (4%) metastases. Their clinical and imaging features are not very different from secondary bone lesions of other origins. They usually appear(More)
OBJECTIVES Study the effect of hyperbaric oxygen on chronic irradiation induced digestive disorders. PATIENTS AND METHODS A retrospective study was conducted in 36 patients (mean age 66 +/- 11 years) with chronic digestive tract necrosis which had developed a mean 42 months after irradiation therapy. Hyperbaric oxygen therapy was given a mean 17 months(More)
Considerable variation in intravenous 5-fluorouracil (5-FU) metabolism can occur due to the wide range of dihydropyrimidine dehydrogenase (DPD) enzyme activity, which can affect both tolerability and efficacy. The oral fluoropyrimidine tegafur-uracil (UFT) is an effective, well-tolerated and convenient alternative to intravenous 5-FU. We undertook this(More)
The results are reported of cytofluorometric DNA analyses of colorectal tumors using cells obtained by mechanical disruption and fine needle aspiration. The latter method does not lower the level of debris or cell aggregates. We found a significantly higher proportion of aneuploid cells by needle aspiration. There was a good correlation between the data(More)
PURPOSE To evaluate the different respiratory movement management techniques during irradiation of lung tumours. PATIENTS AND METHODS Seven patients with one or more primary or secondary lung lesions less than 5 cm (11 tumours in total) had three computed tomographies (CT): free-breathing, deep-inspiration breath-hold using a spirometer, and 4-dimensional(More)
Large modifications are on going in our medical practice in oncology (cancer incidence, ageing, rules, authorizations, billings...). To obtain the best results as possible implies a quality control of the equipments (drugs, machines...), of the professionals (certification) and of the organisations (accreditations). Radiation oncology plays a key role in(More)
A comparative study was performed on the usefulness of prostate-specific antigen (PSA) and prostatic acid phosphatase (PAP) in control subjects (69), benign prostatic hypertrophy (BPH) patients (150), and patients with prostatic carcinoma (113) in a urology department. We establish, as others, the greater clinical sensitivity of PSA and its effectiveness as(More)
Of 62 patients with rectal carcinoma, who were examined by endorectal ultrasound (EER) before operation, 15 were examined after preoperative external radiation therapy. The results were compared to histological and surgical findings according to the TNM classification. When preoperative radiation therapy was not applied, the diagnostic value of EER was(More)
OBJECTIVES Retrospective evaluation of the prognostic value of pretreatment PSA, PSA nadir and PSA half-life compared to grade and stage after treatment of prostate cancer by radiotherapy. PATIENTS AND METHODS 122 patients (19 T1 (15.6%), 31 T2a (25.4%), 26 T2b (21.3%), 20 T3a (16.4%), 19 T3b (15.6%), 7 Tx (5.7%)) treated by exclusive radiotherapy were(More)
