The thermographic behaviour of bone and soft tissue tumors (168 malignant), submitted to this examination from 1971 to 1981, has been retrospectively analyzed and statistically evaluated. In the group of malignant neoplasms, thermography reached a good sensitivity (81.5%), a little better (but not significantly) in soft tissue tumors. Mainly three pathological features have been analyzed: histological type, size and site of neoplastic masses. None of them appears to be related with the result of thermographic examination. The authors emphasize (also from a possible prognostic point of view) the peculiar behaviour of Ewing's sarcoma, whose tendency to uniform distribution through the different thermographic classes cannot be currently explained.  相似文献

Herein we report the retrospective survey of 48 consecutive unselected cases of vaginal carcinoma, mainly treated with radiotherapy in our Institute from 1959 to 1970. In this series irradiation was delivered almost always with a single and continuous application of sources of radium 226. Radiumtherapy treatment varied according to the extension in surface of the neoplasm, the clinical stage and especially the vaginal step involvement, considering the length of the organ. Despite the very good immediate response, failures of treatment locally or in paravaginal and pelvic areas were frequently observed, and success of the treatment after a brief follow-up was poor. The actuarial survival was 41.6% and 33.3% at 3 and 5 years, respectively. Stage I cases showed at the follow-up better therapeutic results (48.6% survival at 5 years) than stage II and III cases (28.3%). The poorest results were observed in neoplasms extended to the whole vagina, and all these patients died within 4 years of the beginning of treatment. This report stresses that radiotherapy of vaginal carcinomas demands individualization and a properly planned therapeutic program that combines external irradiation with renewed techniques of low dose rate and continuous irradiation with radioactive sources.  相似文献

Although more advanced techniques such as intensity-modulated radiotherapy are rapidly spreading, 3D conformal radiotherapy (3D-CRT) remains the standard of treatment for many diseases. The authors outline essential indications to guarantee the quality of 3D-CRT treatments. Criteria for clinical indications and potential clinical advantages and disadvantages of 3D-CRT technology are presented. After briefly listing human and technological resources requirements, procedures for 3D-CRT and physical aspects peculiar to 3D-CRT are described. Medical physics support activities are also considered, including suggestions concerning quality control protocols. Difficulties in the application of correct quality procedures, particularly related to human and technological resources, procedures for patient positioning, imaging, contouring, treatment planning, in vivo dosimetry, set-up verification, follow-up, dose delivery are then discussed.  相似文献

From January 1975 through December 1983, 74 consecutive patients were given adjuvant radiotherapy on the whole pelvis after radical surgery for locally advanced rectal (44 cases) and rectosigmoidal (30 cases) cancer. Most patients received 45 Gy to the whole pelvis in 5-7 weeks through AP, PA opposed fields. Fourteen patients were also given adjuvant chemotherapy. Minimum follow-up time of the series is 24 months and median follow-up is 36 months. First relapse was evaluated. Pelvic failures occurred in 17.5% of patients, while distant metastases rate was 32%; median time to relapse was 18 and 10 months respectively. Thirty patients (40.5%) never relapsed and are alive and well, while five additional patients are alive with disease. Four patients died of treatment toxicity. Thirty-one patients died of cancer (41.9%); 8 of them from pelvic failure only. Actuarial relapse-free survival at 3 and 5 years was 51.7% and 46.8%, while actuarial overall survival was 63% and 49%.  相似文献

BACKGROUND: Most of the studies on the identification of cardiovascular risk factors have been conducted either in northern Europe or in the United States. However, genetic as well as dietary factors may vary across different countries and geographical areas and there are few data about the cardiovascular risk profile in our country. METHODS: A sample of 3144 subjects (1463 males, 1681 females aged 35-74 years) were randomly selected among the population qualifying for healthcare assistance, registered with 170 general practitioners. Demographic data, clinical information, lab tests and current pharmacological treatments were collected using an electronic case report form. RESULTS: The prevalences of cardiovascular risk factors in the population were: smoking habit 22.7%, obesity 12.8%, hypertension 39.2%, hypercholesterolemia 25.5%, hyperglycemia and diabetes 5.5%. Thirty-five point four percent of the subjects presented a low absolute 10-year cardiovascular risk level (< 5%), 31.1% an intermediate risk (5-9%), 24.9% a moderate risk (10-19%), and 8.6% a high risk (> or = 20%) of developing cardiovascular diseases. CONCLUSIONS: In the area of Verona approximately 20,000 out of 231,592 subjects, aged 35-74 years, may present an absolute 10-year cardiovascular risk level > or = 20%. These results represent the epidemiological basis for planning and implementing preventive interventions toward cardiovascular diseases.  相似文献

PURPOSE OF INVESTIGATION: In order to evaluate the impact of sequential chemotherapy-radiotherapy-chemotherapy on local control and survival, a follow-up study was carried out 12 years after the treatment of 22 patients with FIGO stage IIB-III squamous cell cervical cancer. METHODS: Patients were submitted to three cycles of induction chemotherapy (cisplatin and bleomycin) followed by whole pelvis irradiation and central boost with endocavitary brachytherapy. Ten patients underwent three further cycles of chemotherapy after radiotherapy. All patients were maintained by regular follow-up. Only one patient was lost 48 months after treatment. RESULTS: At the end of treatment complete response was obtained in 14 patients (63.5%). Four of these recurred locally, and one at also distance. Eight patients failed to obtain a complete response. Twelve patients died from disease and one patient died from other causes. Nine of 22 (41%) patients are alive without evidence of disease with a median follow-up of 134 months. Acute toxicity was mild, while two severe late complications were observed. CONCLUSIONS: The achievement of complete remission at the end of treatment is important in terms of life expectancy. Further chemotherapy appears useful for patients who do not reach complete local remission after radiotherapy.  相似文献

Breast cancer is the most frequently diagnosed cancer in women in the western world and a major cause of premature death. Consequently, breast implants are widely used for breast reconstruction. Despite this, the prevalence of implant complications is low. Given widespread use of breast implants, there is an increased awareness of the risk for developing a breast implant associated‐ anaplastic large cell Lymphoma (BI‐ALCL) although rare. Clinical presentation is variable and may include a palpable mass in the breast or axilla, generalized breast pain, or breast firmness. The estimated incidence of BI‐ALCL is <3 per 1 million person years, approximately 0.1‐0.3 per 100 000 women with prostheses per year. Since the publication by Keech and Creech in 1997, which reported the first case of BI‐ALCL, an increasing number of BI‐ALCL have appeared, in patients with both aesthetic and reconstructive indications. In this paper, we describe a patient who was diagnosed with invasive BIA‐ALCL seventeen years after placement of silicone breast implants and was treated with only surgery.  相似文献

In view of its potential action as a growth factor, the evidence of abnormally high blood levels of prolactin (PRL) is associated with a poor prognosis in metastatic breast cancer. Moreover, metastatic breast cancer-related hyperprolactinemia has proven to counteract the efficacy of cancer chemotherapy. The negative influence of high blood levels of PRL on the efficacy of chemotherapy in metastatic breast cancer has been confirmed by previous preliminary studies, showing that the concomitant administration of the anti-prolactinemic dopaminergic agent bromocriptine may enhance the therapeutic effect of chemotherapy. However, the clinical use of bromocriptine is limited by its short duration and gastrointestinal toxicity. Therefore, new anti-prolactinemic drugs, characterized by less toxicity and a longer duration of activity, such as Cabergoline (CBG), could be more appropriated to control PRL secretion in breast cancer. On this basis, a study was planned to evaluate the efficacy and tolerability of a concomitant administration of CBG with weekly low-dose Taxotere (TXT) in pretreated metastatic breast cancer under chemotherapy. The study group comprised 70 metastatic breast cancer patients (females), pretreated with at least one previous chemotherapeutic line containing anthracyclines, who were randomized to be treated with TXT alone or TXT plus CBG. TXT 25 mg/m2 was given i.v. at weekly intervals for at least 9 consecutive cycles. CBG was given orally at 0.5 mg once per week. Abnormally high pre-treatment levels of PRL were seen in 24/70 (34%) patients, 11 of whom were treated with TXT plus CBG, whereas the other 13 received TXT alone. CBG induced a complete normalization of the PRL levels in all patients within the first two weeks of therapy, whereas no normalization of PRL occurred spontaneously in patients treated with chemotherapy alone. The objective tumor regression rate was significantly higher in patients concomitantly treated with CBG than in those who received chemotherapy alone (31/34 vs 13/36, p < 0.05), and this difference was particularly evident in patients with high PRL levels prior to therapy (6/11 vs 2/13). No CBG-related toxicity occurred. On the contrary, chemotherapy-induced asthenia was significantly lower in patients concomitantly treated with CBG (5/34 vs 11/36, p < 0.05). This study shows that the chemoneuroendocrine therapy of weekly low-dose TXT plus the anti-prolactinemic drug CBG is a new, effective and well-tolerated therapy for metastatic breast cancer. It may also be recommended in heavily pretreated patients or in those with poor clinical status.  相似文献
