Lymphatic Microsurgical Preventing Healing Approach (LYMPHA) for primary surgical prevention of breast cancer‐related lymphedema: Over 4 years follow‐up

Breast cancer‐related lymphedema (LE) represents an important morbidity that jeopardizes breast cancer patients' quality of life. Different attempts to prevent LE brought about improvements in the incidence of the pathology but LE still represents a frequent occurrence in breast cancer survivors. Over 4 years ago, Lymphatic Microsurgical Preventing Healing Approach (LYMPHA) was proposed and long‐term results are reported in this study. From July 2008 to December 2012, 74 patients underwent axillary nodal dissection for breast cancer treatment together with LYMPHA procedure. Volumetry was performed preoperatively in all patients and after 1, 3, 6, 12 months, and once a year. Lymphoscintigraphy was performed in 45 patients preoperatively and in 30 also postoperatively after at least over 1 year. Seventy one patients had no sign of LE, and volumetry was coincident to preoperative condition. In three patients, LE occurred after 8–12 months postoperatively. Lymphoscintigraphy showed the patency of lymphatic‐venous anastomoses at 1–4 years after operation. LYMPHA technique represents a successful surgical procedure for primary prevention of arm LE in breast cancer patients. © 2014 Wiley Periodicals, Inc. Microsurgery 34:421–424, 2014.     

Prevalence of oedema of the lower limbs in multiple sclerosis patients: a vascular and lymphoscintigraphic study

The aim of the study was to evaluate the frequency of oedema of the lower limbs in multiple sclerosis (MS) patients utilizing a multidisciplinary approach. A total of 205 patients with definite MS were included in the study. Seventy-five were male and 130 female, with a mean age of 50.53, mean Expanded Disability Status Scale (EDSS) score of 5.27 and mean disease duration of 16.6 years. Seventy-one patients had a relapsing-remitting (RR) disease course, 85 were secondary progressive (SP) and 49 were primary progressive (PP). Ninety-three patients (45%) showed oedema at the examination. EDSS, disease duration and disease course, but not gender, were statistically different between oedema and non-oedema patients. Out of 93 patients with oedema, 69 agreed to undergo a vascular examination. Of 69 patients, 45 (65.2%) had a CEAP score (specific rating scale for oedema) of 3 (presence of oedema) and 24 (34.8%) had a score of 4 (presence of a trophic disorder). Out of 69 subjects, 33 agreed to undergo a lymphoscintigraphy, which was normal in only 29 extremities out of 66. Lower limb oedema is common in MS patients, especially in those with reduced mobility. Early screening is advised in patients with an elevated EDSS.     

Bicalutamide monotherapy versus flutamide plus goserelin in prostate cancer: updated results of a multicentric trial

OBJECTIVES: To compare the efficacy of bicalutamide monotherapy to maximal androgen blockade in advanced prostatic cancer. PATIENTS AND METHODS: Previously untreated patients with histologically proven stage C or D (American Urological Association Staging System) disease were randomly allocated to either bicalutamide (B) or goserelin plus flutamide (G+F). After disease progression, patients treated with B were assigned to castration. The primary endpoint for this trial was overall survival. Prostate cancer-specific survival and progression were included among secondary endpoints. RESULTS: In total 108 patients received B and 112 received G+F. At a median follow-up time of 54 months (range 1-89), 151 patients progressed and 113 died. There was no significant difference in the duration of either progression-free or overall survival. Hazards of progression, death and cancer-specific death, corrected by disease stage, tumor grade and baseline PSA level, showed that patients initially assigned to B had a higher risk of progression but a comparable risk of death and cancer-specific death with the exception of patients with G3 tumors who had an increased risk of death). CONCLUSIONS: In patients with well or moderately well differentiated tumors, B monotherapy followed by castration may offer the same survival chance as maximal androgen deprivation. In those patients it thus represents a reasonable choice that can avoid the side effects of androgen deprivation for considerable periods of time.     

Effects of three cytokine regimens on hematologic recovery and progenitor cell mobilization after high-dose cyclophosphamide, etoposide, and cisplatin

The aim of this study was to compare both the effects on hematologic recovery and circulating progenitor cell mobilization and the toxicity of three cytokine regimens administered after high-dose non-myeloablative chemotherapy with cyclophosphamide 5 g/m(2), etoposide 1.5 g/m(2) and cisplatin 150 mg/m(2). Thirty-five consecutive patients were non-random sequentially allocated to one of three treatment groups: (1) granulocyte colony-stimulating factor alone (n = 15); (2) granulocyte-macrophage colony-stimulating factor alone (n = 10), and (3) sequential interleukin-3 and granulocyte-macrophage colony-stimulating factor (n = 10). Neutrophil recovery in group 1 was significantly hastened as compared to the two other groups (median 2 days, p < 0.005), while no significant differences were observed between groups 2 and 3. CD34+ cells peaked about 2 days earlier in group 1 compared to the other groups (p = 0.0001), whereas the median peak value of CD34+ cells was similar in the three groups. In all patients, the toxicity related to cytokine administration was low and easily manageable with nonsteroidal anti-inflammatory drugs.     

Enterolactone in breast cyst fluid: correlation with EGF and breast cancer risk

The purpose of our study was to investigate whether enterolactone does accumulate into breast cyst fluid and whether it correlates with breast cancer risk. We included 258 women who had at least one cyst aspiration and known intracystic cation and epidermal growth factor (EGF) concentration values. For 191 of such women serum aliquots were also available. The median value of serum enterolactone was 17 nM/l (range 1–140 nM/l). The median intracystic level of enterolactone was much higher (63 nM/l, range 0–872 nM/l) and was significantly higher in type I cysts (p = 0.000). This cyst type contained also significantly higher levels of EGF (p = 0.000). A direct relationship was found between serum and cyst fluid enterolactone levels (p = 0.000) and between cyst enterolactone and EGF levels (p = 0.03), the latter correlation being evident especially in type II cysts. Twelve patients in the cohort of women were found to have developed a breast cancer. After univariate analysis breast cancer risk was associated with cyst type and especially with EGF concentration. No association was evident for enterolactone concentration. However, enterolactone concentration appeared to significantly decrease the risk of patients with high EGF concentrations. Our results show that enterolactone does accumulate in breast cysts, and that it modulates the risk related to the intracystic level of EGF, which is confirmed to be a strong predictor of breast cancer risk.     

Paclitaxel by 72-hour continuous infusion followed by bolus intravenous ifosfamide or epirubicin: results of two phase I studies

STUDY PURPOSES: To determine the maximum-tolerated dose (MTD) of paclitaxel administered by 72-hour continuous infusion followed by bolus intravenous ifosfamide on days 4 and 5 or epirubicin on day 4, every 21 days. To assess the toxicity and preliminary activity in patients with advanced refractory solid tumors. PATIENTS AND METHODS: Sixteen patients with progressive disease after standard chemotherapy for advanced disease were treated with the combination paclitaxel-ifosfamide and 10 patients with the combination paclitaxel-epirubicin. RESULTS: In the first phase I study the MTDs were: paclitaxel 135 mg/m2 and ifosfamide 2.5 mg/m2/day; hematologic toxicity was the dose-limiting toxicity (DLT) during the first cycle of therapy at dose level 4. Paclitaxel administered at 135 mg/m2 and epirubicin 50 mg/m2 were the MTDs in the second phase I study; grade 4 stomatitis was the DLT of this combination. CONCLUSIONS: Paclitaxel by 72-hour continuous infusion followed by bolus ifosfamide was a manageable regimen with an acceptable hematologic toxicity in the absence of neurotoxicity. Preliminary activity of this combination was encouraging in a group of patients with ovarian cancer. The optimal way to combine paclitaxel and epirubicin and the best schedule relative to such a long paclitaxel infusion time in this combination regimen remain to be determined.     

Chylous reflux pathologies: diagnosis and microsurgical treatment.

BACKGROUND: This article aims to make a contribution to the present knowledge of the diagnosis and therapy of chylous reflux pathologies, based largely on the authors' clinical experience in the microsurgical treatment of these disorders. METHODS: In 47 patients affected by chylostatic disorders the diagnosis was based on the clinical history, physical examination, lymphoscintigraphy, lymphography, ultrasound, CT scanning and lymphangio-MR. In cases of chylous reflux towards the external genitalia or the lower limbs, the puncture of one of the lymphostatic verrucae which may be part of the symptomatology, can be sufficient for the clinical diagnosis. If patients suffer from hypoproteinaemia and/or an intestinal malabsorption syndrome, this should be dealt with to ensure them at least temporary metabolic compensation before surgical treatment, if any. In patients affected by chylous ascites, antigravitational ligatures of incompetent collectors, sometimes associated with lymphovenous shunts, can be a therapeutic solution. RESULTS: We have found that CO2 laser irradiation at very low power achieved full section closure of lymphatic and chylous vessels as complete as if they had been tied. In the case of chyloedema of the external genitalia and of/or the lower limbs, reductive plastic treatment completes the result after antigravitational ligatures and derivative microsurgery. CONCLUSIONS: A laser-microsurgical technique used to manage chylous reflux pathologies achieved positive and permanent results, especially after an accurate preoperative diagnostic study to determine the site and nature of the lymphatic and chylous leakage and associated disorders.
