RESUMEN

Sexuality in women with spontaneous premature ovarian insufficiency (POI) deserves attention because of the young age and the distressing impact of such a life-changing diagnosis. Biomedical and psychosocial factors work in concert to determine significant changes of sexual function. Early hormonal deprivation gives origin to symptomatic vulvovaginal atrophy and contributes to hypoactive sexual desire disorder modulating central and peripheral circuitries, which regulate sexual response. Emotional and cognitive adjustment to the short-term and long-term consequences of POI may further determine negative attitudes toward sexuality. It is essential to counsel POI women on every aspect of their life, from menopausal symptoms to fertility concerns, from health risks to potential therapeutic solutions. The biopsychosocial perspective is the best approach to manage sexual symptoms, including tailored hormone therapy and focused counseling. Pharmacotherapies specifically investigated in spontaneous POI conditions are lacking and clinical judgment has to guide the choice of treatment, which must be continued at least until the average age at natural menopause according to the most recent guidelines. Further studies are needed to better characterize POI women and to understand the effective role of novel therapeutic strategies, including androgens and cognitive-behavioral and sexual interventions.

RESUMEN

OBJECTIVES: To evaluate efficacy, tolerability and safety of Monurelle Biogel® vaginal gel for treatment of vaginal dryness. METHODS: Multicenter, national, randomized, controlled vs. no-treatment, open-label study. Ninety-five postmenopausal women were randomized (48 to Monurelle Biogel® and 47 to no treatment). Primary endpoint was the change of Verbal Rating Scale (VRS) total score of vaginal atrophy (VA) symptoms after 8-week treatment. The main secondary endpoints were VRS single-item score, Vaginal Health Index (VHI) score, Maturation Index (MI), Female Sexual Function Index (FSFI), and Female Sexual Distress Scale-Revised (FSDS-R). RESULTS: The VRS total score was statistically significant in favor of the treatment group on day 28 (p = 0.001) but not on day 56 (p = 0.064). By excluding women who were not sexually active, the total VRS scores reached the criteria for clinical success in 27/43 subjects (62.8%) in the control arm and in 38/46 subjects (82.6%) in the treatment arm (p = 0.035) on day 56. The VHI score significantly changed in the active arm (4.71 ± 4.85 vs. 0.28 ± 1.71) (p < 0.001) on day 56. Even the MI significantly improved, with an increase in the percentage of superficial cells (p = 0.01). The improvements in both VHI and MI were still present at the follow-up visit after the discontinuation of the treatment (day 84). Sexual function and distress showed a statistical significant difference on day 56. CONCLUSIONS: Monurelle Biogel® vaginal gel applied twice daily for 8 weeks is effective in relieving vaginal dryness and other VA symptoms. Such a clinical meaningful effect persists at least 4 weeks and is supported by an improvement in the vaginal environment. Trial Registration clinicaltrials.gov Identifier: NCT02994342.

RESUMEN

OBJECTIVE: This study will investigate the reproducibility and influencing factors of exhaled breath temperature measured with the tidal breathing technique in asthmatic patients and healthy children. METHODS: Exhaled breath temperature, fractional exhaled nitric oxide, and spirometry were assessed in 124 children (63 healthy and 61 asthmatic), aged 11.2 ± 2.5 year, M/F 73/51. A modified version of the American Thoracic Society questionnaire on the child's present and past respiratory history was obtained from parents. Parents were also asked to provide detailed information on their child's medication use during the previous 4 weeks. Ear temperature, ambient temperature, and relative-ambient humidity were also recorded. RESULTS: Exhaled breath temperature measurements were highly reproducible; the second measurement was higher than the first measurement, consistent with a test-retest situation. In 13 subjects, between-session within-day reproducibility of exhaled breath temperature was still high. Exhaled breath temperature increased with age and relative-ambient humidity. Exhaled breath temperature was comparable in healthy and asthmatic children; when adjusted for potential confounders (i.e. ambient conditions and subject characteristics), thermal values of asthmatic patients exceeded those of the healthy children by 1.1 °C. Normalized exhaled breath temperature, by subtracting ambient temperature, was lower in asthmatic patients treated with inhaled corticosteroids than in those who were corticosteroid-naive. CONCLUSION: Measurements of exhaled breath temperature are highly reproducible, yet influenced by several factors. Corrected values, i.e. normalized exhaled breath temperature, could help us to assess the effect of therapy with inhaled corticosteroids. More studies are needed to improve the usefulness of the exhaled breath temperature measured with the tidal breathing technique in children.

RESUMEN

BACKGROUND: Fat grafting is widely carried out in breast cancer patients to improve quality in breast reconstruction. Recently, in vitro and animal studies have questioned the role of adipose tissues in cancer development. DESIGNS: Matched-cohort study. We analysed: (i) 59 intraepithelial neoplasia patients who had undergone lipofilling, with no recurrence between primary surgery and lipofilling. (ii) A control group of 118 matched patients (two controls per lipofilling patient) with the corresponding recurrence-free intervals. Both groups were also matched for main cancer criteria. A local event (LE) was the primary end point, with follow-up starting from the baseline. RESULTS: Median follow-up was 63 and 66 months from surgery, and 38 and 42 from baseline, for the lipofilling and control groups, respectively; the 5-year cumulative incidence of LE was 18% and 3% (P = 0.02). Ki-67 was the significant factor in univariate survival analysis. A subgroup analysis showed that lipofilling increased the risk of LE in women <50 years, with high grade neoplasia, Ki-67 ≥ 14 or who had undergone quadrantectomy. CONCLUSION: Higher risk of LE was observed in intraepithelial neoplasia patients following lipofilling. Although further studies are required to validate our conclusions, patients belonging to this subgroup should be informed of these results and the potential risks.

RESUMEN

BACKGROUND: Lipofilling has been indicated for postmastectomy and postlumpectomy breast reconstruction. The clinical literatures underline its technical efficacy but experimental studies raise important questions about the potential detrimental effect of adipocytes on the stimulation of cancer growth and reappearance. DESIGN: We collected 321 consecutive patients operated for a primary breast cancer between 1997 and 2008 who subsequently underwent lipofilling for reconstructive purpose. For each patient, we selected two matched patients with similar characteristics who did not undergo a lipofilling. RESULTS: Eighty-nine percent of the tumors were invasive. Median follow-up was 56 months from the primary surgery and 26 months from the lipofilling. Eight and 19 patients had a local event in the lipofilling and control group, respectively, leading to comparable cumulative incidence curves [P = 0.792; Hazard Ratio(Lipo vs No lipo) = 1.11 (95% confidence interval 0.47-2.64)]. These results were confirmed when patients undergoing quadrantectomy and mastectomy were analyzed separately and when the analysis was limited to invasive tumors. Based on 37 cases, the lipofilling group resulted at higher risk of local events when the analysis was limited to intraepithelial neoplasia. CONCLUSIONS: Lipofilling seems to be a safe procedure in breast cancer patients. Longer follow-up and further experiences from oncological series are urgently required to confirm these findings.

RESUMEN

We investigated the influence of nipple areolar complex (NAC) sparing in mastectomy, on patient satisfaction with cosmetic results, body-image, sexuality and psychological well-being. We developed a specific questionnaire and compared two groups of women who underwent radical mastectomy with immediate breast reconstruction (IBR). Between 2004 and 2006, 310 women with NAC preservation and 143 patients with successive NAC reconstruction were mailed the questionnaire at follow-up 1 year after definitive complete breast reconstruction surgery. 256 questionnaires was available. Our results showed significant differences in favour of the NAC sparing group regarding body image (difficulty in looking at themselves naked and being seen naked by their partners after surgery, P = 0.001 and P = 0.003, respectively); regarding satisfaction with the appearance of the nipple (P < .0001) and with the sensitivity of the nipple (P = 0.001); regarding the feeling of mutilation (P = 0.003). NAC sparing in mastectomy has a positive impact on patient satisfaction, body image and psychological adjustment.

RESUMEN

In order to reduce mutilation, nipple-areola complex (NAC) conservation can be proposed for the treatment of breast cancer when mastectomy is indicated. To reduce the risk of retro areolar recurrence, a novel radiosurgical treatment combining subcutaneous mastectomy with intraoperative radiotherapy (ELIOT) is proposed. One thousand and one nipple sparing mastectomies (NSM) were performed from March 2002 to November 2007 at the European institute of oncology (EIO), for invasive carcinoma in 82% of the patients and in situ carcinoma in 18%. Clinical complications, aesthetic results, oncological and psychological results were recorded. A comparison was performed between the 800 patients who received ELIOT and the 201 who underwent delayed one-shot radiotherapy on the days following the operation. The median follow up time was 20 months (range 1-69) for a follow up performed in 83% of the patients. The NAC necrosed totally in 35 cases (3.5%) and partially in 55 (5.5%) and was removed in 50 (5%). Twenty infections (2%) were observed and 43 (4.3%) prostheses removed. The median rate of the patients for global cosmetic result on a scale ranging from 0 (worst) to 10 (excellent) was 8. Evaluation by the surgeon in charge of the follow-up gave a similar result. Only 15% of the patients reported a partial sensitivity of the NAC. Of the fourteen (1.4%) local recurrences, ten occurred close to the tumour site, all far from the NAC corresponding to the field of radiation. No recurrences were observed in the NAC. In a group of patients characterized by a very close free margin under the areola, no local recurrence was observed. Overall, 36 cases of metastases and 4 deaths were observed. No significant outcome difference was observed between the 800 patients receiving intraoperative radiotherapy (ELIOT) and the 201 patients receiving delayed irradiation.

RESUMEN

BACKGROUND: When the conservative treatment is not recommended, Nipple Sparing Mastectomy (NSM) is proposed more and more frequently for the surgical treatment of breast cancer. The risk of local recurrence behind the nipple areolar complex (NAC) is the main limiting factor of the NSM procedure. To minimize such risk, we proposed in 2002 a intraoperative radiotherapy of the preserved NAC. PATIENTS AND METHODS: From March 2002 to November 2006, 579 cases (in 570 patients) of NSM were performed for carcinoma. The median follow up time was 19 months (Range: 1-60). The subcutaneous mastectomy was performed through an incision removing a portion of the skin overlying the tumour. An extemporaneous histological examination was performed on the retroareolar glandular tissue. If the histology was positive the patient was not considered eligible. Then an intraoperative radiotherapy with electrons (ELIOT) of 16 Gy in one shot was delivered on the NAC area. An immediate breast reconstruction was done using implants in most cases and in several cases a musculocutaneous flaps, usually in large breast. The number of local recurrences was recorded and the correlation between their occurrence and the clinical and histological criteria were analysed using the Gray test statistical method in a competing framework. RESULTS: In 516 cases the negative retroareolar frozen section biopsy was confirmed by the final histology, while in 63 cases, the final histology showed foci of carcinoma. Seven out of these 63 cases underwent a secondary NAC removal. In the 56 cases which preserved areolas we did not observe any local recurrence after 19 months follow up. The probability of retro areola positive histology increases with the tumour size. and was not related to the nodal status. The rate of local relapses was 0.9% per year. We didn't find any significant difference in the local relapse rate according to different patient's and tumour's features. Most relapses were located close to the tumour bed but never in the NAC area. CONCLUSION: Our study confirms that the local recurrence rate in the NSM completed with local radiotherapy on the NAC is not higher than the usual rate observed in the literature and the preservation of the NAC does not increase the risk. The absence of local recurrence in the region where a portion of glandular tissue has been purposely preserved is a good argument in favour of ELIOT.

RESUMEN

BACKGROUND: Reconstruction of the breast after mastectomy is an integral part of the complete management of breast cancer. However, a delay in the reconstruction is usually proposed after the mastectomy in case of invasive cancer, while there is a general agreement for immediate breast reconstruction in case of in situ tumors. PATIENTS AND METHODS: Among a total of 677 patients having undergone a mastectomy between 1997 and 2001, 518 (76.5%) underwent an immediate breast reconstruction (IBR). All the patients had a Patey mastectomy for invasive cancer (T1-T3). An adjuvant medical treatment was given according to the biological characteristics of the tumor and lymph node status. No patient received any kind of radiotherapy. The median follow up was 70 months (range 13-114). RESULTS: The local recurrence rate was 5.2% for the group of IBR and 9.4% for the mastectomy group without IBR (NoIBR). The regional metastases rate was 1.4 vs. 1.3%. The rate of distant metastases was 13.9 vs. 16.4%. Contra-lateral breast tumor was observed in 1.5 vs. 1.3%. Death rate was 10.4 vs. 16.4%. No statistical difference was observed between the two groups in terme of overall survival (OS) and disease free survival (DFS) (HR(IBR vs. NoIBR): 1.03 and 0.99 for OS and DFS, respectively). CONCLUSION: At our institution we have compared a large series that have undergone IBR (518) with a control group (159) and followed over a prolonged period of time (70 months). This study provides the best available results to suggest that IBR is a safe and reliable treatment option for the managing invasive breast cancer.

RESUMEN

Smoking is harmful for respiratory function. In young to middle-aged men the damage is insidious and difficult to demonstrate. The respiratory impairment could increase under specific stressful conditions in the professional environment. On the hypothesis that exhaled markers are useful for assessing airway susceptibility to inhaled irritants, we measured exhaled markers and lung function in smoking and non-smoking engine-driver military coastguards before and after a patrol at sea. Eighteen men, mean age 39 yrs (range 23-58 yrs), 8 smokers, underwent spirometry, exhaled and nasal nitric oxide (eNO, nNO), exhaled carbon monoxide (CO) and exhaled breath condensate (EBC) for measures of hydrogen peroxide (H2O2), leukotriene B4 (LTB4), proteins (Prots), 8-isoprostanes (8-IsoPs), nitrite (NO2-) and nitrosothiols (RS-NOs) at baseline and after an 8-hour patrol navigation on board small, high-speed diesel-powered ships. At baseline, the smokers showed higher middle flows and CO levels, lower eNO and nNO than non-smokers, but similar levels of EBC markers; geometric means (95% confidence interval), CO: 23.6 (14.5 to 38.3) vs. 3.5 (2.5 to 5.3) ppm; eNO: 7.9 (4.8 to 12.9) vs. 26.7 (15.7 to 45.5) ppb, p=0.000. After navigation, Prots, 8-IsoPs and RS-NOs (but not lung function variables or other markers) significantly increased only in smokers; baseline vs post-navigation RS-NOs: 0.27 (0.11 to 0.65) vs. 1.30 (0.58 to 2.89) micromol, p=0.012. The respiratory consequences of a stressing environment in engine-driver military coastguards who actively smoke are better assessed by measuring EBC markers than by eNO, nNO or lung function. By increasing airway inflammation from oxidative-stress, tobacco smoking appears to interact with other chemical or physical factors elicited during sea navigation. Precisely what these factors are deserves further investigation.

RESUMEN

The preservation of the nipple areola complex (NAC) could improve the quality of life in cases of mastectomy. A novel radiosurgical treatment combining subcutaneous mastectomy with intraoperative radiotherapy is proposed. Three hundred nipple-sparing mastectomies (NSM) were performed. Invasive (58%) and in situ (42%) carcinomas were included. Clinical complications, aesthetic results, oncological and psychological results were recorded. The NAC necrosed totally in 10 cases and partially in 29 and it was removed in 12. Nine infections (3%) were observed and 10 prostheses removed. Good results were rated by 82.3% of the patients and by 84.8% of the surgeons. In 7.5% a radiodystrophy was observed. The sensitivity of the NAC recovered partially in 48%. Two local recurrences occurred outside the radiated field. Overall, we observed three metastases and no deaths. Sixty-eight of the patients were satisfied with their reconstructed breast and 85.5% were satisfied having preserved the NAC.

RESUMEN

The aim of the study was to investigate the blood supply of the normal nipple areola complex (NAC) and the spared areola complex after a nipple-sparing mastectomy using the analysis of the fluorescence from the indocianine green dye (ICG) injection. Between December 2002 and July 2003 we performed the ICG analysis in 10 cases of healthy breasts and in 9 patients after a nipple-sparing mastectomy and one patient after subcutaneous mastectomy. In all cases, the resulting fluorescence was measured in three different zones: nipple, areola, surrounding mammary skin. Three parameters of the fluorescence curve (slope, maximum intensity, time to achieve a maximum level) were recorded. On the healthy breast, the nipple showed a very high perfusion as compared to the other zones. On the contrary, after the mastectomy the fluorescent pattern was completely altered, being the perfusion of the nipple very low. In conclusion, these preliminary results confirm the applicability and the importance of the ICG technique for evaluating the perfusion of the healthy and spared areola after surgery. Because of the small number of patients further studies are needed.

RESUMEN

The concentration of exhaled nitric oxide (eNO) is a useful marker of asthmatic bronchial inflammation. eNO can now be measured away from the laboratory (off-line), even in children. Short exhalation maneuvers (8 sec) and small samples (1 L) of exhaled gas are probably sufficient in children, but more information is needed about the effect of different measurement conditions. As a preliminary step before conducting epidemiological studies in schoolchildren, we investigated the effects of expiratory flow, dead space, and expiratory time on eNO concentrations collected in 1-L mylar collection bags. We studied 101 cooperative subjects (62 males) aged 5-18 years (30 healthy volunteers, 51 asthmatics, and 20 children with various other respiratory diseases) in our pulmonary function laboratory. On-line and off-line eNO were compared in a single session, and analyzed with a Sievers NOA 280 nitric oxide analyzer. For both methods of collecting expired gas, subjects did a single exhalation without breath-holding against an expiratory pressure 10 cm H(2)O. We investigated the effects of expiratory flow, dead space, and exhalation time on eNO; we also compared on-line and off-line eNO measurements, and the repeatability of both techniques at a given flow rate. Expiratory flows of 58 mL/sec provided more reproducible data than lower flows (coefficient of repeatability 1.1 ppb for 58 mL/sec vs. 2.8 for 27 mL/sec vs. 5.7 for 18 mL/sec). eNO concentrations were about 25% higher in off-line than in on-line recordings if the initial 250 mL of exhaled gas were not eliminated, and 37% higher if exhalation lasted longer (16 sec vs. 8 sec). Eliminating 250 mL of dead space and shortening the filling time to 8 sec yielded off-line eNO values close to those on-line (geometric mean off-line eNO 14.4 ppb, 95% confidence interval: 12.2-17.0) vs. on-line eNO 13.8 ppb (95% confidence interval: 11.6-16.5). On-line and off-line results were highly correlated (r = 0.996, P = 0.000) and had similar coefficients of variation (on-line eNO 2.6%, off-line 2.8%). Neither agreement nor repeatability of eNO measurements were affected by disease status or baseline FEV(1) (% predicted values). Once standardized, the off-line eNO technique using 1-L gas collection bags will provide results similar to those recorded on-line.

RESUMEN

The present immunohistochemical study provides the first evidence of the presence of calcium-binding proteins (CaBPs) in the epidermis of the earthworm Lumbricus terrestris (Annelida, Oligochaeta) a lower invertebrate. The entire epidermis was labelled for calmodulin which is in agreement with its ubiquitous occurrence. Immunopositivity for calbindin D28K was limited to mucous cells, while that for S-100 protein was present only in neuroendocrine-like small granular cells. Finally, labelling for parvalbumin was specifically present in the subcutaneous nerve plexus. S-100 protein is considered to be a marker of neuroendocrine cells, at least in lower invertebrates such as Annelida. Although calbindin D28K is considered to be a marker of these cells in vertebrates, the same function cannot be attributed in Lumbricus terrestris. However, we can conclude that S-100 protein, as a regulatory protein, is phylogenetically older than calbindin D28K. We assume that the latter has an autoregulatory function in secretory processes. In agreement with previous data, we suggest that small granular cells exert a paracrine action in osmoregulatory and secretory processes.

RESUMEN

Carbohydrate residues were localized in the glandular cells of the epidermis of Lumbricus terrestris by lectin histochemistry. The following biotinylated lectins were used: ConA, PNA, WGA, UEA-I. Each lectin has a specific binding pattern in the epidermal glandular cells. The ConA binding is evident in the orthochromatic mucous cells; PNA in the metachromatic mucous cells; WGA in the neuroendocrine-like cells; UEA-I in the cuticle. The epidermal glandular cells possess specific sites for the different lectins in relation to their functional characteristics. Therefore, these sugar residues indicate different behaviours of the cells in epidermal functions related to ion transport, receptor-secretory processes and defence.

RESUMEN

Serotonin (5HT), endothelin-big (ET-big) and neuron-specific enolase (NSE) are present in some epithelial paraneuronal cells of vertebrates. In the invertebrates, we show for the first time, by immunofluorescence and immunoperoxidase methods, the immunoreactions to antibodies raised to ET, 5-HT and NSE in the epidermis of the Lumbricus terrestris. It is assumed that the reactive cells are small granular cells that may have a paracrine action in the mechanisms of cell proliferation and secretory processes. The function of these bioactive substances in the epidermis of the earthworm awaits investigation. Phylogenetically it is very interesting that paraneuronal-like type of cells appear in such an ancient species of invertebrate which uses the epidermis for various functional activities.

RESUMEN

Left varicocele (LV) is a common clinical condition that is present in approximately 15% of the general male population. Bilateral varicocele (BV) is an association of clinical LV and subclinical or ultrasound diagnosed right varicocele. Recent diagnostic technology suggests that BV is much more common than previously suspected varying from 15 to 57%. The laparoscopic technique offers the possibility of planning bilateral varix ligation but only a few reports are currently available. The aim of this study was to evaluate the outcome of contemporary bilateral correction of BV on spermatogenesis. From 1992 January to 1998 December a total of 207 patients with clinical left varicocele and a pathological sperm count were studied. Scrotal sonography was performed and in 96 patients (group A) subclinical right varicocele was diagnosed while 111 patients (group B) only had LV. 84 patients were married and had tried unsuccesfully for a pregnancy for at least one year before evaluation. All patients underwent laparoscopic varicocelectomy, performed under general anesthesia with a three trocar technique with application of clips to the spermatic vein and resection. Patients with right reflux received bilateral varix ligation. Operating time averaged 28 minutes for unilateral cases and 42 minutes for bilateral legatures. No significant differences were found in age distribution or preoperative seminal paramenters between the two groups. Postoperative hospital stay was 1.2 and 1.3 days respectively. 168 patients underwent sperm count four to six months after surgery. Both groups showed improvements in number (group A 41 millions, group b 27 millions), 2nd hour motility (group A 32%, group B 19%) and morphology (group A 52%, group B 51%). 95 patients achieved normalization of seminal parameters, 40 (63%) in group A and 37 (30%) in group B, and there was a statistically significant difference between the two groups. The pregnancy rate was calculated on married population after one year; it was 41% in total. The role of the subclinical right varicocele associated to clinical left varicocele is uncertain and there are few papers concerning this argument. In this serie normalization of seminal parameters and the pregnancy rate were significantly higher in patients with bilateral correction of reflux. In conclusion our data confirm that subclinical right reflux also has a detrimental effect on spermatogenesis and we suggest that it must be corrected contemporary when associated with clinical left varicocele.

RESUMEN

BACKGROUND: Non-invasive assessment of airway inflammation is particularly useful in children. The exhaled breath temperature (EBT) may reflect inflammatory vasodilation and serve to assess respiratory symptoms and therapy with inhaled corticosteroids (ICs). AIMS: To compare EBT with other non-invasive measurements in unselected schoolchildren in relation to respiratory symptoms and IC-therapy, as well as to assess reproducibility, and potentially influencing factors. METHODS: In 298 Italian schoolchildren, we assessed tidal-EBT, FE(NO), spirometry, skin-prick tests, questionnaires on chronic respiratory symptoms, and medication. Subjects were divided as follows: reported wheeze, respiratory symptoms other than wheeze, and without symptoms. RESULTS: Subjects with reported wheeze (n = 30) more frequently presented atopy, respiratory symptoms, higher FE(NO), lower lung function than subjects with symptoms other than wheeze (n = 141) and those without symptoms (n = 127), but had a similar EBT. IC-treated children (5 wheeze, 9 respiratory symptoms other than wheeze, 4 without chronic symptoms) had lower median (interquartile range) EBT levels than IC-untreated children (n = 280) [EBT: 31.7 (30.1-32.5) vs. 32.6 (31.4-33.4), P = 0.027]. Duplicate EBT measurements were highly reproducible (ICC = 0.94). In a multiple linear-regression model, EBT was explained by age, weight, duration of EBT measurement, FE(NO), and ambient temperature (r = 0.63, P < 0.001). CONCLUSION: Tidal-EBT measurements are easy to perform, reproducible, though symptom misclassification may affect the results obtained regarding the effect of IC therapy. Factors influencing EBT should be addressed in further epidemiological studies.

RESUMEN

BACKGROUND: A small but significant proportion of patients with breast cancer (BC) will develop loco-regional recurrence (LRR) after immediate breast reconstruction (IBR). The LRR also varies according to breast cancer subtypes and clinicopathological features. METHODS: We studied 1742 consecutive BC patients with IBR between 1997 and 2006. According to St Gallen conference consensus 2011, its BC approximations were applied to classify BC into five subtypes: estrogen receptor (ER) and/or progesterone receptor (PgR) positive, HER2 negative, and low Ki67 (<14%) [luminal A]; ER and/or PgR positive, HER2 negative and high Ki67(≥ 14%) [luminal B/HER2 negative]; ER and/or PgR positive, any Ki67 and HER2 positive [luminal B/HER2 positive]; ER negative, PgR negative and HER2 positive [HER2 positive/nonluminal]; and ER negative, PgR negative and HER2 negative [triple negative]. Cumulative incidences of LRR were compared across different subgroups by means of the Gray test. Multivariable Cox regression models were applied. RESULTS: Median follow up time was 74 months (range 3-165). The cumulative incidence of LRR was 5.5% (121 events). The 5-year cumulative incidence of LRR was 2.5% for luminal A; 5.0% for luminal B/HER2 negative; 9.8% for luminal B/HER2 positive; 3.8% for HER2 non luminal; and 10.9% for triple negative. On multivariable analysis, tumor size (pT) >2 cm, body mass index (BMI) ≥ 25, triple negative and luminal B/HER2 positive subtypes were associated with increased risk of LRR. CONCLUSION: Luminal B/HER2 positive, triple negative subtypes and BMI ≥ 25 are independent prognostic factors for risk of LRR after IBR.

RESUMEN

BACKGROUND: Fat grafting is largely used to correct soft-tissue defects in any region of the human body. This study analysed its safety when the technique is used to correct defects after breast-cancer reconstruction. METHODS: A total of 158 patients who underwent 194 breast fat grafting procedures were analysed. Almost all patients (98%) had a personal history of breast cancer: conservative surgery or mastectomy with breast reconstruction. In all cases, fat grafting was performed according to the Coleman's technique by a single surgeon. RESULTS: Immediate complications included liponecrosis and infection in seven cases (3.6%) that required only daily dressings and oral antibiotics administration. In cases of fat grafting after conservative surgery, only four patients (5.9%) showed minor alterations in the postoperative mammograms, consisting of the appearance of benign images. CONCLUSION: Breast fat grafting can be a good solution to repair defects after breast-cancer treatment and reconstruction, and can reduce the indication for more extensive surgeries such as myocutaneous flaps. Postoperative complication rates are very low and there is little alteration in follow-up mammograms. Two points remain unclear--how much of the fat is absorbed after grafting and the potential risk of local 'dormant' tumour cells being stimulated to induce a local recurrence.
