Advanced carcinoma of the hypopharynx: functional results after circumferential pharyngolaryngectomy with flap reconstruction

Surgical treatment of advanced cancers of the hypopharynx inevitably impairs swallowing, respiration and phonation. The purpose of this study was to analyze the functional results after circumferential pharyngolaryngectomy (CPL) and flap reconstruction, in order to offer decisional guidelines for the choice of the most effective reconstructive method. We performed a retrospective analysis on the medical records of patients submitted to reconstructive surgery after CPL from July 1991 to November 2011. 75% of the 94 patients underwent reconstruction with a free flap (group A), while 25% underwent reconstruction with a pedicled flap (group B); 80% of patients in group A and none in group B were discharged with a free diet; 14% of patients in group A and 26% in group B were unable to resume oral feeding and were discharged with NG-tube or PEG. None of the patients acquired a satisfactory oesophageal voice; 17% of patients in group A and 7% in group B underwent voice restoration with tracheo-oesophageal voice-prosthesis. In conclusion, free flaps should be considered the first choice for reconstruction of the hypopharynx after CPL because of the better functional results obtained. Pedicled flaps represent a valid alternative in patients with contraindications to microvascular surgery

[Accepted Manuscript] Can dietary and physical activity modifications reduce breast density in postmenopausal women? The DAMA study, a randomized intervention trial in Italy.

Few randomized trials have been carried out to evaluate the effect of lifestyle modifications on mammographic breast density (MBD). The randomized 2x2 factorial DAMA trial aimed to evaluate whether MBD can be reduced in post-menopausal women with high baseline MBD by a 24-months dietary and/or physical activity (PA) interventions. We randomized healthy post-menopausal women, attending the Florence (Italy) mammographic screening program, aged 50-69 years, non-smokers, with MBD>50% and no recent hormone therapy, to: a) a dietary intervention focused on plant-foods, with a low glycemic load, low in saturated fats and alcohol; b) a PA intervention combining daily moderate intensity activities and one weekly supervised session of more strenuous activity; c) both interventions; d) general recommendations. We evaluated changes in MBD based on VolparaTM estimates comparing baseline and follow-up digital mammograms by an intention-to-treat-analysis. MBD measures were available for 226 participants. An interaction emerged between treatments and thus we run analyses by arms. A decrease in volumetric percent density emerged for women in the dietary intervention (ratio 0.91; 95%CI 0.86-0.97; p=0.002) and in the PA intervention arm (0.93; 95%CI 0.87-0.98; p=0.01) in comparison with controls. No clear effect emerged in the double intervention arm. This intervention trial suggests that a 24-months dietary or PA intervention may reduce MBD in postmenopausal women. A modification of dietary habits or an increase in PA in postmenopausal women may reduce MBD. Further studies are needed to confirm these findings for planning breast cancer preventive strategies

Patients' survival after free flap reconstructive surgery of head and neck squamous cell carcinoma : a retrospective multicentre study

Head and neck squamous cell carcinoma of the (HNSCC) represents approximately 5% of malignant tumours in Italy. HNSCC are commonly treated with surgery or radiotherapy, or a combination of such therapies. The objectives of treatment are maximum cure rate balanced with organ preservation, restoration of form and function, reduction of morbidities and improvement or maintenance of the patient's quality of life. Immediate reconstructive surgery: local, regional or free flaps are now widely advised in the treatment of these patients. Microsurgical transfer requires expertise, is time and resource consuming, and as a whole requires substantial costs. These considerations introduce some concerns about the wide or indiscriminate use of free flap reconstructive surgery. When considering cost-benefit outcomes of such treatment, the main objective is undoubtedly, survival. This data is underreported in the current literature, whereas functional outcomes of free flaps have been largely diffused and accepted. This study collects data from 1178 patients treated with free flap reconstructive surgery following ablation of HNSCC in a group of Italian tertiary hospitals, all members of the Head & Neck Group affiliated with the Italian Society of Microsurgery. According to many authors, free flap surgery for HNSCC seems to be a beneficial option for treatment even in terms of survival

Pedicled flaps represent a valid alternative in patients with contraindications to microvascular surgery

Integrated treatment in locally advanced carcinoma of the oropharynx.

Oropharyngeal carcinoma tends to be aggressive and deeply infiltrative of nearby sites, with an high incidence of lymph node metastases. The last treatment decision generally depends on the stage of the lesion and the patient's general status. Oropharyngeal tumor is generally treated by integrated treatments.We retrospectively studied 115 patients with locally advanced oropharyngeal tumors treated in our institution with combined therapies compare the results in two different groups of patients (surgery plus radiotherapy and chemotherapy plus radiotherapy).The 3-year overall survival rate in patients who underwent surgery plus radiotherapy was 82\% and in those who underwent chemotherapy plus radiotherapy was 49\%.The results suggest that surgery followed by radiotherapy seems to be the best treatment in the case of locally advanced oropharyngeal tumor

Electrochemotherapy as a new therapeutic strategy in advanced Merkel cell carcinoma of head and neck region.

Merkel Cell Carcinoma (MCC) is a rare and aggressive tumour, arising from a cutaneous mechanoceptor cell located in the basal layer of epidermis, with poor prognosis. The treatment of choice for the initial stage of the disease is surgery and/or radiotherapy. The treatment of recurrent or advanced disease is still controversial.We report a case of 84 years old woman with a recurrent MCC of the chin treated with electrochemotherapy (ECT). During the period of 20 months, four sessions of ECT were employed, which resulted in an objective response of the tumour and good quality of residual life.Our case shows the effectiveness of ECT in the treatment of locally advanced MCC of the head and neck region in a patient not suitable for standard therapeutic options

The role of computed tomography in the preoperative assessment and follow-up of oromandibular reconstruction with microvascular osteomyocutaneous free flaps

Objective: To investigate the capacity of helical CT in the pre- and post-operative management of oromandibular reconstruction of patients with oropharyngeal carcinoma using microvascular composite free flaps. Materials/methods: Thirty-four patients with oropharyngeal cancer were examined by helical CT and nine (six men and three women) submitted to oromandibular reconstruction. The osteomyocutaneous flaps used for reconstruction were taken from the iliac crest in six cases and from the fibula in three cases. All patients were examined by CT 1-4 days postoperatively and then at 6 monthly intervals. Double helical scans were performed in all cases, with slices of 2-3 mm for primary lesion studies and 5 mm for lymph node staging, pitch greater than or equal to 1 and RI=1. Multiplanar (MPR) and 3D reconstructions were obtained from pre- and postoperative CT examinations. Results: Preoperative CT showed massive bone infiltration in six of the nine surgical patients and marginal infiltration in three. These findings were confirmed histologically. There were no false negatives. The immediate postoperative examination showed correct flap positioning in eight of nine cases. The flap underwent ischemic necrosis in two cases; CT showed very early signs of bone ischemia in both. CT detected two cases of recurrence after about 1 year. Conclusions: Axial CT permitted adequate assessment of the extent of mandibular infiltration and detected early ischemic complications and distant recurrences. Integration with MPR and 3D reconstructions simplified the choice of flag type and size and enabled the postoperative assessment of correct flap positioning. This helped the surgeon plan subsequent rehabilitation with osseo-integrated implants

Physical activity and blood pressure in 10,000 Mediterranean adults: The EPIC-Florence cohort

Background and aims The relevant role of physical activity (PA) in cardiovascular risk prevention is widely agreed. We aimed to evaluate, in a large Mediterranean population, the influence of PA on systolic (SBP) and diastolic blood pressure (DBP), taking into account individual characteristics and lifestyle habits. Methods and results In the Florence section of the European Prospective Investigation into Cancer and Nutrition 10,163 individuals, 35â\u80\u9364 years, without a previous diagnosis of hypertension were recruited. Information on occupational and leisure-time PA and blood pressure were collected at recruitment, together with data on lifestyle, dietary habits and anthropometry. Multivariate regression models were applied to evaluate the effect of total, occupational and leisure-time PA on SBP and DBP. Mean values of SBP and DBP in the study subjects were 124.4 (SD 15.6) and 79.7 mmHg (SD 9.4), respectively. Overall, a total PA index and an index including cycling, fitness and occupational PA (Cambridge index) were inversely associated with DBP (beta â\u88\u920.87, p-value 0.02 actives vs inactives, p for trend 0.02 and beta â\u88\u920.84, p value 0.003 actives vs inactives, p for trend 0.002, respectively), while SBP was associated only with the latter index (beta â\u88\u921.14, p-value 0.01 actives vs inactives, p for trend 0.006). An inverse association emerged between manual/heavy manual occupation and DBP (p 0.02, ref sedentary/standing occupation) and between increasing cycling activity and SBP (p for trend 0.04). Conclusions In this large cohort of Mediterranean adults without a diagnosis of hypertension we confirm the role of overall PA in modulating SBP and DBP values. Cycling and manual occupations were associated with lower DBP values
