Capsular Contractures

Radiation therapy is an integral component of the treatment of breast cancer. Although its implementing after breast reconstruction sufficiently increases the number of complications, particularly capsular contractures. After having analyzed published materials and meta-analysis research the authors made a conclusion – if a patient is planned to have a breast reconstruction, it’s better to make it with her own tissue. On the other hand the risk of capsular contractures development significantly decreases when using acellular matrix and polyurethane shell to cover the implant. This fact gives hope that conflict between breast reconstruction and the necessity of the radiation therapy can be solved.

Abstract. Two experiments examined the influence of stories on recipients’ self-perceptions. Extending prior theory and research, our focus was on assimilation effects (i.e., changes in self-perception in line with a protagonist’s traits) as well as on contrast effects (i.e., changes in self-perception in contrast to a protagonist’s traits). In Experiment 1 ( N = 113), implicit and explicit conscientiousness were assessed after participants read a story about either a diligent or a negligent student. Moderation analyses showed that highly transported participants and participants with lower counterarguing scores assimilate the depicted traits of a story protagonist, as indicated by explicit, self-reported conscientiousness ratings. Participants, who were more critical toward a story (i.e., higher counterarguing) and with a lower degree of transportation, showed contrast effects. In Experiment 2 ( N = 103), we manipulated transportation and counterarguing, but we could not identify an effect on participants’ self-ascribed level of conscientiousness. A mini meta-analysis across both experiments revealed significant positive overall associations between transportation and counterarguing on the one hand and story-consistent self-reported conscientiousness on the other hand.

ABSTRACT:ALS symptom spread results from local spread of the neuronal degeneration because contiguous areas are more quickly involved than non-contiguous areas. Local spread to contiguous areas of motor neuron dysfunction is faster at the brainstem, cervical and lumbar regions than spread to non-continguous areas. The time for caudal-rostral symptomatic spread of ALS to involve a distant region is a function of the distance of that region from the site of onset. The time for spread to the bulbar region is shorter following arm onset than leg onset. Spread to non-contiguous areas is faster within the spinal cord than from the spinal cord to the bulbar region. These kinetics are consistent with axonal transport of the etiological agent in a manner similar to spread of poliovirus in poliomyelitis patients. Spread from the bulbar region to the spinal cord, on the other hand, occurs faster than symptom spread from the limb region to the bulbar region in limb onset patients. This rapid limb involvement following bulbar onset is more dramatic in males compared with females. Females with leg onset, on the other hand, show more rapid involvement of the opposite leg, either arm or bulbar structures than males. Gender effects may determine the course of ALS depending on the original site of onset.

PURPOSE: Recent randomized trials in women with node-positive breast cancer who received systemic treatment report that locoregional radiation therapy improves survival. Previous trials failed to detect a difference in survival that results from its use. A systematic review of randomized trials that examine the effectiveness of locoregional radiation therapy in patients treated by definitive surgery and adjuvant systemic therapy was conducted. METHODS: Randomized trials published between 1967 and 1999 were identified through MEDLINE database, CancerLit database, and reference lists of relevant articles. Relevant data was abstracted. The results of randomized trials were pooled using meta-analyses to estimate the effect of treatment on any recurrence, locoregional recurrence, and mortality. RESULTS: Eighteen trials that involved a total of 6,367 patients were identified. Most trials included both pre- and postmenopausal women with node-positive breast cancer treated with modified radical mastectomy. The type of systemic therapy received, sites irradiated, techniques used, and doses of radiation delivered varied between trials. Data on toxicity were infrequently reported. Radiation was shown to reduce the risk of any recurrence (odds ratio, 0.69; 95% confidence interval [CI], 0.58 to 0.83), local recurrence (odds ratio, 0.25; 95% CI, 0.19 to 0.34), and mortality (odds ratio, 0.83; 95% CI, 0.74 to 0.94). CONCLUSION: Locoregional radiation after surgery in patients treated with systemic therapy reduced mortality. Several questions remain on how these results should be translated into current-day clinical practice.

CRA532 Background: The purpose of the study was to compare treatment outcomes in patients with breast cancer treated with partial breast irradiation and of those treated with whole breast radiation therapy. Methods: We conducted a systematic review and meta-analysis of published. Randomized clinical trials comparing partial breast irradiation versus whole breast radiation therapy. Primary outcome was overall survival and secondary outcomes were locoregional, distant and supraclavicular recurrences. Results: A search of the literature identified 3 trials with pooled total of 1,140 patients. We found no statistically significant difference between partial and whole breast radiation arms associated with death (OR 0.912, 95% CI 0.674–1.234, p = 0.550), distant metastasis (OR 0.740, 95% CI, 0.506–1.082, p = 0.120), or supraclavicular recurrences (pooled OR 1.415, 95% CI 0.278–7.202, p = 0.560). However, partial breast irradiation was statistically significantly associated with an increased risk of both local (pooled OR 2.150, 95% CI, 1.396–3.312; p = 0.001) and regional disease recurrences (pooled OR 3.430, 95% CI, 2.058–5.715; p < 0.0001) compared with whole breast radiation. Conclusions: Partial breast irradiation does not jeopardize survival and may be used as an alternative to whole breast radiation. Nevertheless, the issue of locoregional recurrence needs to be further addressed. No significant financial relationships to disclose.
