Mastectomy versus radiotherapy as treatment for stage I-II breast cancer: A prospective randomized trial at the National Cancer Institute

In 1979, the National Cancer Institute in Bethesda, Maryland initiated a randomized, prospective trial to compare surgery versus radiation therapy in the treatment of stages I and II breast cancer. Surgical treatment consists of total mastectomy with axillary lymph node dissection (modified radical mastectomy) and breast reconstruction; radiation treatment consists of gross tumor excision, axillary lymph node dissection, and comprehensive irradiation including a boost dose to the tumor bed. All patients with pathologically positive axillary nodes receive 11 cycles of adjuvant Adriamycin ® /Cytoxan ® chemotherapy. As of December 1984, there have been 175 patients entered in the study. Twenty-three patients have developed disease recurrence (12 mastectomy, 11 radiation), but it is too early to obtain definitive treatment-related results. En 1979 l'Institut National du Cancer de Bethesda a lancé une étude prospective randomisée permettant de comparer les résultats respectifs de la chirurgie et de la radiothérapie en ce qui concerne les stades I et II du cancer du sein. Le traitement chirurgical consiste en la mastectomie totale complétée par le curage ganglionnaire axillaire (mastectomie totale modifiée); le traitement dit radiothérapique consiste en l'exérèse large de la tumeur associée au curage ganglionnaire axillaire et à l'administration d'une dose élevée de rayons au niveau du lit tumoral. Toutes les opérées dont les ganglions sont envahis reçoivent en outre 11 cycles d'une combinaison d'Adriamycine et Cytoxan. De 1979 à Décembre 1984, 175 malades ont fait l'objet de cette étude. Vingt-trois ont accusé une récidive (12 après mastectomie et 11 après traitement dit radiothérapique) mais il est encore trop tôt pour tirer des conclusions définitives de ces résultats. El Instituto Nacional de Cáncer de Bethesda inició en 1979 un ensayo prospectivo y aleatorio orientado a comparar el tratamiento quirúrgico versus radioterapia en el manejo del cáncer mamario en estados I y II. El tratamiento quirúrgico consistió de mastectomía total con disección ganglionar axilar (mastectomía radical modificada) y reconstrucción mamaria; el manejo radioterapéutico consistió de resección del tumor, disección de los ganglios linfáticos axilares e irradiación comprensiva incluyendo una dosis de refuerzo al lecho tumoral. Todos los pacientes con ganglios axilares histológicamente positivos recibieron 11 ciclos de quimioterapia adyuvante con Adriamicina/Citoxán. Hasta diciembre de 1984, 175 pacientes habían entrado al estudio. Veintitrés pacientes han desarrollado recurrencia de la enfermedad (12 mastectomía, 11 irradiación), pero es todavía muy temprano para derivar resultados definitivos.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/41319/1/268_2005_Article_BF01655179.pd

Anxious Personality and Breast Cancer: Possible Negative Impact on Quality of Life After Breast-Conserving Therapy

Background Quality of Life (QoL) is an important outcome measure in oncology. To assess the influence of surgical treatment and personality on QoL in women with breast cancer, a longitudinal prospective cohort study was done. Methods Women (n = 222) completed questionnaires concerning QoL (WHOQOL 100) and personality (NEO-FFI and STAI) prior to the diagnosis of breast cancer and 1, 3, 6, and 12 months after diagnosis and treatment. One hundred five women were treated with breast-conserving therapy (BCT) and 117 women underwent mastectomy (MTC). Results The two treatment groups did not differ on overall QoL. At all measurement times the influence of trait anxiety on overall QoL was substantial in the BCT group. Women with a high score on trait anxiety were seven times more likely to have a low overall QoL 1 year after BCT. In the MTC group overall QoL was influenced mainly by neuroticism. Conclusions Personality, especially trait anxiety and neuroticism, determined patients' overall QoL scores. Women with an anxious personality fared worse concerning QoL after breast conserving therap

Graduating dentists’ perceptions about their professional competence in Finland and Lithuania

Abstract Aims: Efforts to harmonise dental education in Europe have been put into action by the Association for Dental Education in Europe (ADEE). The aim of the study was to explore graduating dentists’ perceptions about their professional readiness for clinical work in Finland and Lithuania. Materials and methods: The survey targeted fifth‐year dental students at the University of Oulu and the University of Turku in Finland, and at the Lithuanian University of Health Sciences, Kaunas, Lithuania (Lithuanian and international students) in 2016‐2017. The competences were evaluated in the questionnaire in 21 dental procedures based on ADEE competences by options: “I’d manage well,” “I’d need more training” or “It would not quite succeed.” The option “I’d manage well” was chosen in the analyses. Results: Students felt that they were most competent in producing and maintaining accurate patient records (91.9%), implementing sterilisation and hygiene in dental practice (91.3%) and working with other members of dental team and health profession (90.0%). The largest differences between Finnish and Lithuanian students were in designing and adjusting occlusal splints (87.0% vs. 14.3%) and in undertaking subgingival scaling (95.7% vs. 57.1%). The biggest differences between Lithuanian and international students were in identifying (and treating) abnormal and anxiety‐related patient (73.1% vs. 25.5%) and implementing tobacco cessation (65.3% vs. 31.9%). Conclusions: The graduating dental students in Finland and Lithuania manage well in most of the clinical procedures based on the ADEE competences. The students were most confident when dealing with tasks that are common in dental practice
