positive axillary sentinel lymph node is axillary dissection always necessary

Summary There is considerable interest in foregoing axillary dissection (AD) when the sentinel node (SN) is positive in early breast cancer, particularly when axillary involvement is minimal (micrometastases or isolated tumor cells). In fact, clinical practice has run ahead of the evidence, since recent population-based data indicate that AD is 'underused' in breast cancer patients when the SN is positive. Several trials are addressing the problem (IBCSG 23-01, ASCOG Z0011, EORTC AMAROS). Only Z0011 has published interim results, finding, after a median follow-up of 6.3 years, no differences in locoregional recurrence or regional recurrence between patients, with a positive SN, who received AD vs. no further axillary treatment. Our own retrospective study evaluated patients with micrometastases or isolated tumor cells in the SN who received no further axillary treatment. We found high five-year survival and low cumulative incidence of axillary recurrence, supporting the findings of Z0011 and justifying the increasingly common practice of foregoing AD in women with minimal SN involvement. It is important to sound a note of caution however: If axillary dissection is not always necessary in women with a positive axilla, it seems important to be able to reliably identify the patients at high risk of developing overt axillary disease who should receive elective AD. Ancillary analyses of the IBCSG 23-01 and AMAROS trials, still in follow-up, may be able to do this

local therapy for breast cancer in malignant lymphoma survivors

Summary Aims: Breast cancer is the most frequent secondary tumor in young women previously treated with mantle radiation for Hodgkin's disease. Prior therapeutic radiation to the breast region is considered an absolute contraindication to breast conservative surgery, and mastectomy is considered the treatment of choice. We performed a retrospective review to assess the potential of performing breast conservative surgery and intraoperative radiotherapy with electrons (ELIOT), in these patients. Methods and results: Forty-three patients affected by early breast cancer, previously treated with mantle radiation for malignant lymphoma, who underwent breast conservative surgery and ELIOT, were identified in our institution. Median age at diagnosis of lymphoma was 26 years (49% were less than 25). Median interval between lymphoma and breast cancer occurrence was 19 years. A total dose of 21 Gy (prescribed at 90% isodose) in 39 patients (91%), of 17 Gy (prescribed at 100% isodose) in 1 patient and 18 Gy (prescribed at 90% isodose), was delivered. ELIOT was well tolerated in all patients without any unusual acute or late reactions. After a median follow-up of 52 months, local recurrence occurred in 9% of the patients and metastases in 7% patients. Conclusion: In patients previously treated for lymphoma, partial breast irradiation, and in particular ELIOT, permits breast conservative surgery without acute local complications, decreasing the number of avoidable mastectomies

breast conserving surgery in 201 very young patients 35 years

Abstract Introduction Surgical treatment of breast cancer in very young patients ( Patients and Methods We retrospectively evaluated outcome and prognostic factors of 201 consecutive patients treated with breast conservation followed by whole breast irradiation between 1997 and 2004 with special attention paid to local control. The average follow up was 72 months (range 13–133 months). Results The mean age was 32 years (Range 20–34). Invasive ductal carcinoma was found in 175 (87.1%) patients. Two (1%) patients had invasive lobular carcinoma. One-hundred and eighteen patients (58.7%) had tumors of 2 cm or smaller. Sentinel lymph node biopsy was performed in 105 (52.2%) patients. One-hundred and ten (54.7%) patients had node-negative disease, 68 (33.8%) patients had 1–3 positive nodes and 23 (11.4%) +4 positive nodes. Eighteen patients (9.0%) developed a local recurrence, 25 (12.5%) developed distant metastases and 23 patients (11.4%) died during follow up. The 5- and 10-year cumulative incidence of local events were 8.2% and 12,3% respectively. The univariate analysis did not identify any variables affecting local disease-free survival. Conclusions Breast conservation in very young patients achieves an acceptable local control rate. No prognostic factors were associated with local events

Extracellular proteasome-osteopontin circuit regulates cell migration with implications in multiple sclerosis

Osteopontin is a pleiotropic cytokine that is involved in several diseases including multiple sclerosis. Secreted osteopontin is cleaved by few known proteases, modulating its pro-inflammatory activities. Here we show by in vitro experiments that secreted osteopontin can be processed by extracellular proteasomes, thereby producing fragments with novel chemotactic activity. Furthermore, osteopontin reduces the release of proteasomes in the extracellular space. The latter phenomenon seems to occur in vivo in multiple sclerosis, where it reflects the remission/relapse alternation. The extracellular proteasome-mediated inflammatory pathway may represent a general mechanism to control inflammation in inflammatory diseases

Conociendo y comprendiendo interacciones entre pares que generan dinámicas agresivas entre estudiantes de primero a quinto de básica primaria del instituto Rafael Núñez de la sede del barrio porfía, 2012

En la vida moderna se vive a un ritmo en el cual las relaciones afectivas se deterioran cada vez más, y la comunidad escolar por supuesto no escapa de ella; por ello el propósito de esta propuesta se efectúo con el fin de comprender las dinámicas que se presentan entre los estudiantes del plantel educativo Rafael Núñez, en el cual se observó mediante algunas visitas que los niño(a)s interactúan agresivamente. Para esta propuesta, se eligió como muestra un grupo de 60 estudiantes de básica primaria con edades entre los 6 a 13 años de la comunidad estudiantil Rafael Núñez, donde se evidenció que éste establecimiento, no es ajeno al fenómeno de las interacciones agresivas en el momento de realizar algunas acciones comunicativas entre pares; algunas de ellas se encuentran frente al entorno educativo de forma verbal o física y otras no, manteniendo así un bajo perfil no por esto menos impactantes; en muchas ocasiones estas presiones se presentan de manera grupal y acaban por coaccionar al más débil de la relación, generando un conflicto e imposibilitando de este modo establecer relaciones adecuadas entre los estudiantes. Este estudio se efectúa ya que los problemas de manifestaciones agresivas en niños, han sido motivo de estudio desde diversos contextos (legal, social, educativo y médico), y en distintas partes del mundo, por sus graves consecuencias en la formación integral del niño y en su personalidad futura como adulto. Con el propósito de acompañar a la comunidad educativa mediante el desarrollo de estrategias psicosociales, para estimular relaciones solidarias, pacificas y afectuosas, surgieron alternativas de desarrollo de habilidades individuales e inter-grupales en las aulas escolares, logrando mejorar con esto prácticas de comunicación humana, las relaciones consigo mismo, con los demás, con el entorno, en donde se da un abordaje de conflictos a fin de mejorar el clima escolar y transformar la cultura institucional, para lo cual se usó el desarrollo de las temáticas: habilidades sociales, relaciones humanas, comunicación humana y abordaje de conflictos.In modern life is lived at a pace which affective relations deteriorate more and more, and the school community of course not escape from it, hence the purpose of this proposal was made to understand the dynamics present among students of campus Rafael Nunez, which was observed by several visits to the child’s interact aggressively. For this proposal, was chosen as a sample group of 60 primary school students aged 6 to 13 years of the student community Rafael Nunez, where it was shown that this facility is no stranger to the phenomenon of aggressive interactions at the time to perform some communicative actions between pairs, some of them are facing the educational environment of verbal or physical and not others, thus maintaining a low profile is no less impressive, in many cases, these pressures are presented in groups and eventually coerce the weaker the relationship, creating a conflict and thus impossible to establish appropriate relationships with students. This study was done because the problems of aggressive manifestations in children, have been studied from different contexts (legal, social, educational and medical), and in different parts of the world for its serious consequences in the integral formation of children and in its future as an adult personality. In order to accompany the educational community through the development of psychosocial strategies to encourage supportive relationships, peaceful and loving, there were alternatives to develop individual skills and inter-group in the classroom, getting better with this practice of human communication, relationships with self, others, with the environment, where there is a conflict management to improve school climate and transform the institutional culture, which was used for the development of themes: social skills, human relations , human communication and conflict management

R-CVP versus R-CHOP versus R-FM for the initial treatment of patients with advanced-stage follicular lmphoma: results of the FOLL05 trial conducted by the Fondazione Italiana Linfomi

PURPOSE Although rituximab (R) is commonly used for patients with advanced follicular lymphoma (FL) requiring treatment, the optimal associated chemotherapy regimen has yet to be clarified. PATIENTS AND METHODS We conducted an open-label, multicenter, randomized trial among adult patients with previously untreated stages II to IV FL to compare efficacy of eight doses of R associated with eight cycles of cyclophosphamide, vincristine, and prednisone (CVP) or six cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or six cycles of fludarabine and mitoxantrone (FM). The principal end point of the study was time to treatment failure (TTF). Results There were 534 patients enrolled onto the study. Overall response rates were 88%, 93%, and 91% for R-CVP, R-CHOP, and R-FM, respectively (P=.247). After a median follow-up of 34 months, 3-year TTFs were 46%, 62%, and 59% for the respective treatment groups (R-CHOP v R-CVP, P=.003; R-FM v R-CVP, P=.006; R-FM v R-CHOP, P=.763). Three-year progression-free survival (PFS) rates were 52%, 68%, and 63% (overall P=.011), respectively, and 3-year overall survival was 95% for the whole series. R-FM resulted in higher rates of grade 3 to 4 neutropenia (64%) compared with R-CVP (28%) and R-CHOP (50%; P< .001). Overall, 23 second malignancies were registered during follow-up: four in R-CVP, five in R-CHOP, and 14 in R-FM. CONCLUSION In this study, R-CHOP and R-FM were superior to R-CVP in terms of 3-year TTF and PFS. In addition, R-CHOP had a better risk-benefit ratio compared with R-FM

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.
