Bilateral mammoplasty for cancer: Surgical, oncological and patient-reported outcomes.

INTRODUCTION: Bilateral mammoplasty (BM) can optimise oncological safety and aesthetic outcomes in women with large or ptotic breasts whose tumour to breast volume ratio or tumour location pose a challenge to standard breast-conserving therapy (BCT) and for whom mastectomy (with or without reconstruction) may be the only alternative. METHODS: We undertook a comprehensive analysis of surgical outcomes (complications according to the Clavien Dindo classification), acute radiation morbidity (Radiation Therapy Oncology Group classification), oncological outcomes, and patient satisfaction (BREAST-Q questionnaire) in women who underwent BM for breast cancer (BC) from June 2009-November 2014. RESULTS: 168 women were included. Median age was 55 years (range:33-84) and median tumour size at imaging 35 mm (range:0-170). Median specimen weight was 242 g (range 39-1824). The wise pattern technique was used in 87.5% of procedures. At least one complication occurred in 68 (40.5%) women, mostly Clavien Dindo grade 1. Grade 3 complications were infrequent (8.9%) but occurred mainly on the therapeutic mammoplasty (TM) side (p < 0.05). Complications were associated with higher BMI, specimen weight and longer time to radiotherapy (p < 0.05). Median follow-up was 37 months (range: 13-77). Local recurrence occurred in 3 (1.8%), distant metastases in 5 (3.0%), and 10 (6.0%) women have died. The median score for 'satisfaction with breasts' was 77 (range: 0-100). CONCLUSIONS: This study provides concurrent data on surgical, oncological and patient-reported outcomes. It offers evidence that BM is an effective treatment for breast cancer in large- or ptotic-breasted women.

Standard wide local excision or bilateral reduction mammoplasty in large-breasted women with small tumours: Surgical and patient-reported outcomes.

INTRODUCTION: Oncoplastic breast surgery is used to extend the role of breast-conserving surgery (BCS) to women with an unfavourable tumour to breast volume ratio. However, large-breasted women with a relatively small breast cancer may be offered bilateral reduction mammoplasty (BRM) despite being suitable for standard BCS as the more complex surgery may have advantages in terms of patient satisfaction and reduced adverse effects of radiotherapy. PATIENT AND METHODS: This retrospective study evaluated surgical and patient-reported outcome measures (PROMs) in large-breasted women with early (<3 cm) breast cancer, who have undergone unilateral standard BCS or BRM. RESULTS: This series included 157 women, 87 in the unilateral BCS group and 70 in the BRM group. Median age was 60.2 years (range: 33-83.9). Median follow-up was 36 months (range: 9.8-76). Tumour size, rates of axillary dissection, adjuvant chemotherapy and tumour bed irradiation boost were significantly greater in the BRM group (p < 0.05). The surgical complication rate was not significantly different (43.7% vs. 34.3%, p = 0.253). Re-excision rates were higher in the standard BCS group (p < 0.05). Time to chemotherapy was similar, but time to radiotherapy was longer after BRM surgery (p = 0.025). Despite worse prognostic factors, more complex surgery and more aggressive adjuvant treatment, patients report better satisfaction and physical functioning and fewer adverse effects of radiotherapy after BRM than standard unilateral BCS. This difference was not statistically different in this small study (p > 0.05). CONCLUSION: Limitations of this study mean it can only be regarded as hypothesis-generating. Nonetheless, the trends merit a prospective study to investigate the optimal management of smaller breast cancers in larger-breasted women.

The first case of acinic cell carcinoma of the breast within a fibroadenoma: case report.

A case of acinic cell carcinoma of the breast is reported in a 26-year-old woman. She presented a lump in her right breast, that seemed to be a fibroadenoma. The open biopsy revealed a well-bordered fibroadenoma, together with a proliferation of cells characterized by serous acinar differentiation and eosinophilic cytoplasmic granules. Tumor cells stained for amylase, lysozyme, α-1-antichymotripsin, epithelial membrane antigen, S-100 protein, pan-cytokeratin, cytokeratin 7 and E-cadherin. Estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2 overexpression, CD10, P63, smooth muscle actin, cytokeratin 5/6 were negative. The sentinel node was negative. 8 months after surgery she is in good clinical conditions without recurrence or metastases.

Acinic cell carcinoma of the breast: review of the literature.

INTRODUCTION: The breast and salivary gland tissue share embryologic and thus pathological similarities. Acinic cell carcinoma (ACC) is a typical tumor in salivary glands, but rarely arises in breast too. We reviewed 38 cases of mammary ACC reported in literature and our case, the first ACC born within a fibroadenoma. MATERIALS AND METHODS: Data were collected by a research for the key words acinic cell carcinoma breast on Pubmed in March 2014, including a case treated in our department. All reviewed cases were compared for clinical approach and histological pattern. RESULTS: To date 23 articles presenting cases of ACC of the breast are reported in literature. We included in our review 38 cases previously described and one new case. The histological pattern was predominantly solid with a microglandular structure. All the tumor cells were cytologically characterized by monotonous round cells with a finely granular, weakly eosinophilic, or clearly vacuolated cytoplasm. The most of the cells were intensely stained with anti-lysozime, anti-amylase, anti-α1-chimotripsin, anti-EMA and anti-S100 protein antisera. Immunohistochemistry was also performed to point out: estrogen receptor (ER), progesterone receptor (PR), androgen receptors (AR), human epidermal growth factor receptor 2 overexpression (HER2/neu), E-cadherin (E-cad), cytokeratin-7 (CK7), gross cystic disease fluid protein 15 (GCDFP15), smooth muscle actin (SMA). CONCLUSION: ACC of the breast is a rare tumor, showing similarities with the salivary gland counterpart, above all in terms of good prognosis, and differences from the ordinary invasive breast carcinoma. Further investigations are needed to elucidate the true histogenesis and the correct treatment.

Oncogene-induced reactive oxygen species fuel hyperproliferation and DNA damage response activation.

Oncogene-induced reactive oxygen species (ROS) have been proposed to be signaling molecules that mediate proliferative cues. However, ROS may also cause DNA damage and proliferative arrest. How these apparently opposite roles can be reconciled, especially in the context of oncogene-induced cellular senescence, which is associated both with aberrant mitogenic signaling and DNA damage response (DDR)-mediated arrest, is unclear. Here, we show that ROS are indeed mitogenic signaling molecules that fuel oncogene-driven aberrant cell proliferation. However, by their very same ability to mediate cell hyperproliferation, ROS eventually cause DDR activation. We also show that oncogenic Ras-induced ROS are produced in a Rac1 and NADPH oxidase (Nox4)-dependent manner. In addition, we show that Ras-induced ROS can be detected and modulated in a living transparent animal: the zebrafish. Finally, in cancer we show that Nox4 is increased in both human tumors and a mouse model of pancreatic cancer and specific Nox4 small-molecule inhibitors act synergistically with existing chemotherapic agents.

Positive findings in preoperative testing prior to gastric banding: their real value.

AIM: Relations between laparoscopic adjustable gastric banding (LAGB), gastroesophageal reflux (GER) and hiatal hernia (HH) are controversial. In this context the role of preoperative investigations to assess upper gastrointestinal (GI) function and its impact on the approach to LAGB and outcomes remains unclear. The aim was to define the value of preoperative upper GI testing, and to relate the findings with postoperative outcomes. METHODS: Seventy-eight cases were enrolled among 250 patients undergoing LAGB from January 2010 to December 2011 in our Center for the Multidisciplinary treatment of severe obesity. Patients were submitted preoperatively to endoscopy and radiologic series with oral contrast to assess the state of upper GI mucosa, the presence of HH, GER or cardias incontinence. According to the findings, patients were assigned to group A, if one or both exams showed positive results; or to the control group B if both exams were negative. RESULTS: GI series showed GER in 14.1% of patients, HH in 6.4%, altered motility in 5.1%, gastritis in 3.1%and were negative in 75.6%. Endoscopy showed gastritis in 71.8%of patients, HH in 30.8%, esophagitis in 7.7%, duodenitis in 7.7%, LES incontinence in 8%; while only 21.8% of patients had a negative exam. Differences between group A and B are not statistically significant in terms of pre- and post-operative BMI, EBWL%, long-term complications, time and number of regulations. CONCLUSION: Positive findings in preoperative testing rarely postpone or change the surgical approach and postoperative outcomes. Our results encourage the omission of upper GI series from routine evaluation protocol prior to LAGB.

Gastric emptying after sleeve gastrectomy: statistical evidence of a controlled prospective study with gastric scintigraphy.

AIM: Laparoscopic sleeve gastrectomy (LSG) is a stand-alone bariatric procedure, its feasibility and efficacy being confirmed by long-term data. The effect of the procedure is believed to be based on the gastric restriction and reduction of ghrelin. Nevertheless it remains still controversial the role of LSG on gastric emptying and the impact that this may have on weight loss outcomes. Our aim is to assess gastric emptying after LSG using gastric scintigraphy. METHODS: For this prospective randomized study, 45 patients undergoing LSG at our Centre for the Multidisciplinary Treatment of Severe Obesity from April 2009 to April 2011 were enrolled and observed prospectively (Group A). The inclusion criteria followed the guidelines for bariatric surgery. All patients performed gastric emptying scintigraphy through a standard semisolid meal (250 kcal), marked with 0.5 mCiTc 99. Group A performed the exam before (A1) and after the operation (A2). A control group (Group B) included 20 patients undergoing scintigraphic assessment for other reasons. RESULTS: LSG was performed following a standardized technique. No complications were observed. The scintigraphic study showed a reduced half-life tracer (A1 vs. A2: 80.4±16.5 min vs. 64.3±22 min P=0.06), without a significant difference. Comparing the two groups no differences occurred before operation (B vs. A1). Gastric emptying time resulted significatively reduced in group A2 rather than in group A1 and B. CONCLUSION: Gastric motility plays a role in the pathogenesis of obesity. Our experience suggests that LSG reduces gastric emptying time, but further studies are necessary to reach statystical significativity.

Biliary duct injuries in the laparoscopic era: our experience.

AIM: The main aim of our study is to evaluate the incidence, the type, the causes and the therapy of biliary duct injuries which occurred after the video laparoscopic cholecystectomies performed in our Department during the period from 1990 to 2012. PATIENTS AND METHODS: A retrospective analysis of 1186 VLC has been made in our Department from March 1990 to June 2012. Before the cholecystectomy all patient were evaluated with trans abdominal echography. Beyond the incidence of BDI was evaluated damaging mechanism, etiology, therapy and time of diagnosis. RESULTS: From 1990 to 2012 a total of 9 BDIs occurred, with an incidence of 0,75%. Out of 9 patients 4 had major lesions and 5 had minor lesions; the most common BDI was Strasberg A (45%), the most common etiology was the presence of anatomical variations. In four cases the diagnosis has been intraoperative, in five cases has been postoperative. CONCLUSIONS: Our clinical experience shows that the main cause of BDI are the surgeon experience and the bile ducts anatomical variation.

Use of Tachosil® in bariatric surgery: preliminary experience in control of bleeding after sleeve gastrectomy.

AIM: Laparoscopic sleeve gastrectomy (LSG) is one of the most common procedures of bariatric surgery. Nevertheless complications after LSG are common, the most frequent is bleeding. Our purpose was to reduce bleeding after gastric resection, thus reducing the risk of anemia. METHODS: The study took part in our Multidisciplinary Obesity Treatment Centre, between May 2008 and January 2010. Thirty patients were candidates to SG. They were enrolled in this prospective, parallel group, single-blind randomized trial, to proof the effectiveness and safety of the use of hemostatic-sealant drug Tachosil® as a reinforcement of the suture line in sleeve gastrectomy. Patients were enrolled in Group A when TachoSil® was used and Group B if not. We collected data about weight loss every month, RBC, Hb, PLT, ESR, CRP, WBC in the first week daily and at 2, 4 and 6 months on follow-up. RESULTS: Two groups did not significantly differ for mean age, mean of body weight (118.5 vs. 121.9 kg), BMI (48.4 vs. 49.6 kg/m2), operation time (108 vs. 102 min), hospitalization duration (6.5 vs. 7 days). In group B mean drainage fluid collection was 120, 80 and 60 mL on 1st, 2nd and 3rd postoperative day. Tube removal occurred on average on 5th postoperaive day. In group A (no drainage) control echogram ruled out any fluid collection. RBC, Hb and PLT decreased from 2nd postoperative day. Decrease of PLT was non-significantly different. Decrease of RBC and Hb was significantly different (-0.4 x 106/mL vs. -1.7 x 106/mL; -0.5 g/dL vs. -1.2 g/dL). All other values were not different between groups. CONCLUSION: In this prospective experience the hemostatic-sealant drug Tachosil®, that contains a collagen sponge coated by human fibrinogen and thrombin was shown to reduce post-operatory bleeding and probably promote optimal wound healing.

[Surgical site infections in Italy]. / Le infezioni del sito chirurgico in Italia.

Surgical site infections (SSIs) are recognized as a common surgical complication, occurring in about 2-5% of all surgical procedures. SSIs represent the third most frequent nosocomial infection, accounting for 14.6% of all infections observed in hospitalised patients and 38% of those observed among surgical patients. Strategies for the prevention of SSIs also include surveillance which has proved very effective. The most recent surveillance study carried out at a national level in Italy is Kir-Nos, a multicentric study sponsored by GlaxoSmithKline and performed between April and June 2002 in 32 different General Surgery Units for a total of 2972 surgical patients enrolled. Results emerging from the study clearly indicate that many patients receive inappropriate antimicrobial prophylaxis, especially in terms of drug choice, route and timing of administration. Given the high economic burden that infections provoke, beyond the increased morbidity and mortality, it appears mandatory to improve our tools in order to reduce their incidence, as a reduction of only 0.1% can result in a considerable saving of economic resources to be allocated to other activities, such as screening and prevention programs.

Exploration of cyclical changes in memory and mood in postmenopausal women taking sequential combined oestrogen and progestogen preparations.

OBJECTIVE: To investigate the effect of progesterone on cognitive function, mood, sleep quality and libido when added to oestrogen in sequential combined hormonal replacement therapy regimens. DESIGN: Observational study over three hormonal replacement therapy cycles. SETTING: Menopause Centre of Ospedale Maternità, Bologna, Italy. POPULATION: Twenty-three postmenopausal women with an average of 70 months of amenorrhoea (range 12 to 234 months) on different sequential combined hormonal replacement therapy regimen for an average of 15 months (range 3-48) months. METHODS: Psychological testing for memory, mood, sleep quality and libido during the oestrogen only part of the cycle compared with the oestrogen-progestogen part of the cycle. RESULTS: Twenty women completed the six visits of the trial. The addition of progestogens to oestrogen appeared to benefit memory (P < 0.01) but worsened mood (P < 0.005). There was no evidence of change in other parameters such as sleep quality or libido. CONCLUSION: The addition of progestogens improved memory above what was obtained with oestrogen alone. This effect did not depend on an improvement of mood since the latter worsened during the progestogenic phase of an hormonal replacement therapy cycle. Progestogen added to oestrogen did not significantly influence sleep or libido.

Pyoderma gangrenosum of the cervix.

BACKGROUND: Ulcerated cervical lesions are common findings in gynecology, but pyoderma gangrenosum presenting solely as a cervical ulcer is unusual. CASE: A 33-year-old nulligravida presented with postcoital bleeding and an extensive ulcerated lesion of the cervix that showed nonspecific inflammation on biopsy. After 6 months of topical steroid treatment, the lesion resolved completely. CONCLUSION: Pyoderma gangrenosum should be suspected in nonspecific cervical ulcers, especially those that worsen after surgical resection or ablation and then respond to steroid treatment.

The effect of tibolone versus continuous combined norethisterone acetate and oestradiol on memory, libido and mood of postmenopausal women: a pilot study.

OBJECTIVE: Several studies have shown a positive effect of oestrogen on memory, mood and well-being but these data are controversial and focus particularly on the effect of oestrogen alone. In this pilot study we have investigated the effect of a continuous combination of norethisterone acetate 1 mg and oestradiol valerate 2 mg (Kliogest) versus tibolone (Livial) on memory, sexuality and mood. METHODS: Twenty-two postmenopausal women, age range 51-57, were randomised to a 6 months single blind interventional study treatment with either continuous combined oestradiol plus norethisterone acetate, or tibolone. Computerised psychological test of memory, mood and libido were administered both before and at the end of the 6 months treatment. RESULTS: Fourteen patients completed the study; eight on Livial and six on Kliogest. Recognition memory was improved by Kliogest but not by Livial (P<0.05) while either drug equally improved both the reaction time (P<0.01) and accuracy of performance (P<0.001) of categorical semantic memory. Both the treatments improved libido significantly (P<0.05), while the mood did not change with either. CONCLUSION: The results suggest that both these forms of hormonal replacement therapy improve the efficiency of memory performance and libido. However, a combination of oestradiol and norethisterone acetate seems to be marginally more effective on improving cognitive processes.

Sociodemographic and clinical factors associated with HRT use in women attending menopause clinics in Italy.

OBJECTIVE: The aim of this analysis is to find any association between the use of hormone replacement therapy (HRT) and sociodemographic and clinical factors among women attending 54 menopause clinics in Italy. METHODS: The analysis includes data relating to 17,851 women who attended one of 54 menopause clinics in Italy for general gynecological evaluations and counselling between 1995 and 1997. The characteristics of women reporting ever HRT use were compared with those of never users. The odds ratios (ORs) of HRT use were computed in relation to selected reference categories, together with their 95% confidence intervals (CIs). RESULTS: Of the 17,851 women interviewed, 8539 reported ever HRT use. The mean age of the never and ever HRT users was 52.8 years and 53.7 years, respectively. Higher education was associated with an increased frequency of HRT use: in comparison with women reporting no or primary-/middle-school education, the OR of HRT use of women reporting a high-school diploma or university degree was 1.3 (95% CI 1.1-1.6). HRT use tended to be less frequently reported with increasing body mass index (BMI): in comparison with women whose BMI was < 23.4 kg/m2, the OR of HRT use in those with a BMI of 23.4-26.1 kg/m2 and > or = 26.2 kg/m2 was 0.8 (95% CI 0.8-0.9) and 0.6 (95% CI 0.5-0.7), respectively. Among the postmenopausal women, those who had undergone surgical menopause had an OR of HRT use of 1.3 (95% CI 1.2-1.4). A history of breast cancer was associated with a lower frequency of HRT use (OR 0.3, 95% CI 0.2-0.4). Likewise, a history of thromboembolic disease (OR 0.5, 95% CI 0.4-0.7) or myocardial infarction (OR 0.7, 95% CI 0.6-0.9) was associated with a lower frequency of HRT use. CONCLUSIONS: In our study population, the variable most closely related to HRT use was education/social class, thus underlining the impact of information campaigns on HRT and women's health. Among the medical determinants, our analysis indicates that a history of myocardial infarction, thromboembolic disease or breast cancer is associated with less frequent use of HRT.

Tibolone: a review.

Tibolone appears to be at least as efficacious as other forms of hormonal replacement therapy (HRT) on climacteric symptoms. It does not cause withdrawal bleeding when used in women with at least 1 year of amenorrhea. It is, therefore, not indicated in perimenopause because it may cause irregular bleeding. The androgenic action of tibolone may have a two-fold benefit: on the one hand, it may help depression and libido more than other forms of HRT, while, on the other hand, it may improve some lipid parameters such as Lp(a), and triglycerides. However, this androgenic action, may also be responsible for the reduction of HDL cholesterol, that may thus reduce the beneficial effect of tibolone on lipids. It is estimated that only 30% of cardiovascular risk protection of HRT is due to improvement of classical lipids parameters while a great role is played by the direct effect of estrogen on vessels. Tibolone, as well as estrogen, has been shown to induce peripheral vasodilatation and also has a direct effect on vascular reactivity thus increasing peripheral blood flow with no changes in blood pressure or cardiac output. Tibolone seems to exert a similar effect as other forms of HRT on markers of bone metabolism and bone mass, but no data is yet available on fracture prevention.

Puerperal lactation, gonadotropin release and estradiol release: effects of metergoline and bromocriptine.

The exact cause of amenorrhea during the puerperium is still a matter of debate. PRL might inhibit primarily the release of FSH and LH or their stimulating effects on the ovary. In the study presented here, 28 healthy women were investigated, 13 of them lactating puerperae. In the other 15, lactation was prevented by drugs (metergoline in 9, bromocriptine in 6). The women's serum PRL, FSH, LH, beta-HCG and 17 beta-estradiol as well as their FSH and LH response to LHRH (100 micrograms i.v.) were tested 1, 3, 7 and 14 days after vaginal delivery. Serum PRL levels remained elevated in the lactating puerperae and dropped in the puerperae treated with metergoline or bromocriptine. The pattern of FSH, LH and beta-HCG levels as well as the FSH and LH response to LHRH were superimposable in lactating and in nonlactating women. 17 beta-estradiol levels dropped in all puerperae from day 1 to 7, but rose from day 7 to 14 only in the puerperae treated with metergoline or bromocriptine and not in the lactating women. These data indicate that PRL directly affects the ovarian response to FSH and LH, whereas the release of FSH and LH remains unaffected. A stimulatory effect of metergoline and bromocriptine on the ovarian steroidogenesis cannot be excluded.
