Current Indications for Surgical Treatment of Primary Hyperparathyroidism in the Elderly.

This study presents the results of surgery in the elderly for primary hyperparathyroidism (PHPT) from a single institution's experience. We retrospectively analyzed 898 cases of surgically treated PHPT, divided into two groups: 135 elderly patients (A) and 763 patients younger than 65 years (B). PHPT was symptomatic in 68.8 per cent patients in group A and in 81.6 per cent in group B. Unilateral temporary recurrent laryngeal nerve palsy was observed in 0.9 per cent in group A and 0.1 per cent in group B (P > 0.05). No cervical hematomas, mortality or major cardiovascular, neurological, respiratory or metabolic postoperative complications were registered. All the patients evaluated at one year had improvement in the quality of life, with increase of bone mineral density (BMD) in 85.6 per cent and 79.8 per cent of patients in groups A and B, with no significant differences between symptomatic and asymptomatic patients. Parathyroidectomy in elderly PHPT patients is safe, with rate of morbidity similar to what observed in younger individuals. Further investigations are recommended to confirm the role of surgery as an effective approach in elderly PHPT patients.

Breast cancer and reconstruction: can surgical technique, reconstructive time and adjuvant treatment influence the result?

INTRODUCTION: Some techniques for the total reconstruction of the breast, regardless of the complexity, have specific complications, with varying degrees of morbidity. Therefore, we wanted to identify the most frequent complications of the main techniques used for breast reconstruction, and compare the relation to the relevant independent variables. METHODS: Our study was conducted by examining the medical records of patients who had received complete reconstruction of the breast after a mastectomy due to breast cancer from January 2008 to December 2010, with a minimum follow-up of 3 years postoperatively. The data collected, such as the time of intervention, reconstruction techniques, operating time, and adjuvant treatment, were statistically correlated to the presence of complications. RESULTS: Of the 40 total breast reconstructions analyzed, the technique in which they were used expanders followed by replacement with implants showed the lowest prevalence of complications (16.7%, p <0.000). Some surgical techniques have shown particular complications. The operative time for transplant transverse rectus abdominis musculocutaneous flap (363.57 ± 59.91 min) was significantly higher than that required for the techniques that use alloplastic materials (155.71 ± 38.02 min, p = 0, 01), but similar to that for the latissimus dorsi flap (309.69 ± 77.66 min). The operative time, the timing of reconstructive surgery, and type of adjuvant treatment was not correlated with the incidence of complications. CONCLUSIONS: Each technique has its indications, contraindications and complications. The application of each technique must be tailored to the individual characteristics of each patient.

Thoracic duct lesions in thyroid surgery: An update on diagnosis, treatment and prevention based on a cohort study.

INTRODUCTION: Thoracic duct fistula at the cervical level is a severe but rare complication following thyroid surgery, particularly associated to lateral dissection of the neck and to mediastinal goiter. METHODS: we retrospectively analyzed chylous fistulas observed in a cohort of 13.224 patients underwent surgery for thyroid disease since 1986 to 2014, in the Unit of Endocrine Surgery, S. Maria University Hospital, Terni, Italy. RESULTS: We observed 20 cases of chylous fistula. Thirteen patients underwent primary surgery in our institution while the remaining 7 cases had been referred to our Department from other hospitals for an already diagnosed lymphatic leak. Surgical procedures carried out included total thyroidectomy for mediastinal goiter in 4 patients, total thyroidectomy for cancer in 2 patients, unilateral functional lymphadenectomy in 11 patients and bilateral in 3. Intraoperative repair was carried out in 4 cases. Of the remaining 16 cases, 4 of the 6 fistulas with low flow leakage healed in about 30 days of conservative treatment, 2 cases instead required surgical repair. All 10 patients with "high-flow" fistula underwent surgery. Despite surgery was performed later, postoperative course in patients with late surgical repair is similar to what observed in those patients with early surgical repair. Both groups underwent cervical drainage removal in post-operative day 4. CONCLUSION: Healing of a cervical chylous fistula can be achieved by conservative medical therapy (nutritional and pharmacological) but in case of therapeutic failure with rapid decrease of general condition, the surgical approach is necessary. In our experience, duct ligation after unsuccessful conservative treatment, is the only resolutive treatment.

Surgical approach to mediastinal goiter: An update based on a retrospective cohort study.

AIM: Surgery for mediastinal goiters (MG) is indicated for compression symptoms and risk of malignancy. Total thyroidectomy by cervicotomy is universally considered the standard surgical approach to MG. In selected cases sternotomy or a thoracotomy are used. Options of the operative technique and practical surgical problems are analysed. METHODS: A retrospective analysis of twenty-eight-years on 1767 cases of MG in a referral centre for endocrine surgery was carried out. All patients underwent standard preoperative study and CT based surgical planning. Surgery was performed by an experienced surgical team with standard technique via cervical approach or in selected case via sternotomy or thoracotomy. Clinical records were examined. RESULTS: Total thyroidectomy was performed in all cases. A cervical approach was used in almost 99% of patients. Significant shorter surgical time was observed for surgery via the cervical approach vs sternotomy and thoracotomy. Benign struma was observed in 1503 patients and a carcinoma in 264. We observed postoperative bleeding in 0.5% of cases, permanent monolateral recurrent laryngeal nerve palsy occurred in 1.3%, bilateral palsy in 0.6%, transient and permanent hypoparathyroidism in 14% and 4.1% respectively. CONCLUSION: MG may be approached by a cervicotomic access only with a clear knowledge of potential risk and complications of the surgical manoeuvres. Sternotomy or of a thoracotomy are indicated only in selected cases but their inapplicability may be really dangerous in those MG not otherwise resectable. MG should be referred only to specialized centre.

Approach to lymph node metastases in sporadic medullary thyroid carcinoma An istitutional experience.

AIM: Analyse the impact of aggressive surgical treatment with accurate lymphadenectomy in medullary thyroid carcinoma. MATERIALS AND METHODS: We retrospectively analysed 152 patients affected by medullary thyroid carcinoma, divided in two groups, considering outcome and surgical complications. RESULTS: Primary surgical treatment with thyroidectomy plus central and lateral neck dissection, offers significant reduction in post-operative calcitonin levels, reduced recurrences and limited complications. DISCUSSION: Accurate lymphadenectomy, according to the international guidelines and the main results of clinical studies, is the only treatment combined to total thyroidectomy which offers improved outcome in medullary thyroid carcinoma since inefficacy of chemotherapy and radiotherapy. CONCLUSIONS: Surgery is the unique and fundamental therapy for patients affected by medullary thyroid carcinoma. Extended neck dissection combined to precocious diagnosis and strict follow-up might be considered the standard of treatment of medullary thyroid carcinoma. KEY WORDS: Complications, Lymphadenectomy, Medullary carcinoma, Prognosis.

Surgical morbidity of cervical lymphadenectomy for thyroid cancer: A retrospective cohort study over 25 years.

INTRODUCTION: Prognosis of thyroid cancer is strictly related to loco-regional metastases. Cervical lymphadenectomy has a specific oncologic role but may lead to significant increase of morbidity. Aim of the study is the analysis of surgical morbidity in cervical lymphadenectomy for thyroid cancer. METHODS: We retrospectively analyzed 1.765 thyroid cancers operated over a period of 25 years at S. Maria University Hospital, Terni, University of Perugia, Italy. Type of lymphadenectomy, histology and complications were analysed. RESULTS: A prevalence of differentiated and medullary cancers was observed (respectively 88% and 7.2%). Central lymphadenectomy was carried out in 425 patients, lateral modified and radical lymphadenectomy respectively in 651 and 17 cases. Following central neck dissection we observed: bilateral and unilateral temporary recurrent nerves palsy respectively of 0.7% and 3.5%, unilateral permanent palsy in 1.6% of cases, temporary and permanent hypoparathyroidism respectively in 17.6% and 4.4%. After lateral neck dissection we observed: intra and post-operative haemorrhage respectively in 2% and 0.29%, respiratory distress in 0.29%, lesions of facial nerve in 0.44%, of vagus in 0.14%, of phrenic nerve in 0.14%, of hypoglossal nerve in 0.29%, of the accessory nerve, transient in 1.34% and permanent in 0.29%, permanent lesion of cervical plexus in 0.29%, salivary fistula in 0.14% and chylous fistula in 1.04% of patients. Student's t test was used to compare groups when appliable. CONCLUSION: Central and lateral cervical lymph node dissection are associated to severe morbidity. Correct indication, surgical expertise, high volume of patients and early multidisciplinary management of complications is the key of an acceptable balance between oncologic benefits and surgical morbidity.

Surgical management of mediastinal goiter in the elderly.

AIM: Mediastinal goiter (MG) is characterized by compression symptoms such choking, dyspnea, sleeping apnea and dysphagia. It is significantly observed in elderly patients who due to comorbidity are associated to increased surgical risk. Total thyroidectomy is indicated to treat tracheal compression. Cervicotomy is the most used surgical access. AIM of the study was the evaluation of the role of surgery in the treatment of MG in the elderly. METHODS: A retrospective analysis of twenty-eight-years on 1721 (390 over 80-years-old) cases of MG in a referral center for endocrine surgery was carried out. CT was used as a standard in the preoperative study. Surgery was performed by an experienced surgical team with standard technique via cervical approach or in selected cases via sternotomy or thoracotomy. Clinical records were examined. RESULTS: Patients were divided into two groups: older and younger than 80-years-old. Total thyroidectomy was performed in all cases and via a cervical approach in almost 99% of patients. Tracheal dislocation and tracheomalacia were prevalent in elderly patients and were treated conservatively. Benign struma was observed in 1463 patients and a carcinoma in 258. Larger thyroid weight was observed in the elderly. The rate of complications was similar between groups. CONCLUSION: Total thyroidectomy via cervical approach is the treatment of choice for MG in the elderly. It should be treated only in referral centers with adequate caution for elderly patients to achieve complete cure with limited complications.

The role of surgery in the treatment of thyroid anaplastic carcinoma in the elderly.

INTRODUCTION: Anaplastic thyroid carcinoma (ATC) is characterized by local invasiveness, risk of recurrence and very poor prognosis. METHODS: We retrospectively analysed the multimodality treatment of ATC in 79 patients considering the impact of surgery on survival. RESULTS: Patients were divided in two age groups A and B (cut-off 75 years) and in two size subgroups (cut-off 5 cm). Surgery was performed in 78.5% patients of group A and 32.4% of B (p < 0.05). Radiation respectively in 73.8% and 43.2% (p < 0.05). Tracheostomy and endoprosthesis were used in 45.2% and 16.6% in group A and in 43.2% and 35.1% in group B. The use of tracheostomy was significantly higher (p < 0.05) in larger tumours. In group B comparing operated and not operated patients significant difference in survival was observed for larger tumours (p = 0.043). In Kaplan Meir analysis significant difference in survival was observed comparing surgical and no surgical patients of all four subgroups. Surgery plus radiotherapy offered a significant better outcome in smaller tumours (p = 0.017). Considering the effect of the single treatment, compared to no treatment at all, survival is significantly improved by surgery for smaller and larger tumours respectively with 4.42 (p = 0.001) and with 3.5 months (p = 0.0001) and by radiotherapy respectively with 3.44 and with 3.28 months (p = 0.047 and p = 0.0001). CONCLUSION: In elderly patients with ATC, although poor prognosis, surgery is still fundamental in the multimodality treatment with significant advantage in selected patients. Nevertheless most of elderly patients with large tumours are suitable only for palliative management.

Breast cancer micrometastasis and axillary sentinel lymph nodes frozen section. Our experience and review of literature.

BACKGROUND: Sentinel lymph node (SLN) biopsy plays a major role in the surgical management of primary breast cancer. The aim of this study was to assess the diagnostic accuracy of the assessment of axillary frozen sections of SLNs for micrometastasis diagnosis. PATIENTS AND METHODS: This study focused on 250 SLNs from 137 patients. Each lymph node was fully analyzed by frozen section. After fixation, serial sections were cut and stained by hematoxylin and eosin (HE) and for pan-cytokeratins by immunohistochemistry (IHC). RESULTS: Tumor cells were detected in 57 SLNs, 37 on frozen sections and 20 on controls. Of these 57 positive SLNs, 38 contained metastases, 9 contained micrometastases and 10 contained isolated tumor cells. The specificity and positive predictive value of SLN frozen sections for micrometastasis was 100%. The sensitivity was 83.3% for metastasis, 40% for micrometastasis; the false-negative rate was 16.7% for metastasis and 60% for micrometastasis. CONCLUSION: Analysis of frozen section of SLNs is an accurate method for metastasis detection, allowing concurrent axillary dissection when positive. The protocol for SLN analyses described herein shows good sensitivity for micrometastasis detection.

Intraoperative recurrent laryngeal nerve monitoring in thyroid surgery Evaluation of its use in terms of "spending review".

BACKGROUND: Intra Operative Nerve Monitoring (IONM) has been used in head and neck surgery since the 1970s. Its utilization for monitoring and protecting the recurrent laryngeal nerve, however, is a controversial subject. This paper details the use, value, and cost of this technology within a single institution. METHODS: We conducted a retrospective chart review, analysis of surgery time with and without IONM, analysis of postoperative vocal cord function, and review of the literature RESULTS: IONM did not reduce the operative time during total thyroidectomies in our experience. Use of IONM increased the cost of each surgery by € 450. IONM did not decrease the number of injured nerves (postoperative paresis). CONCLUSIONS: IONM has proven to be highly useful in certain circumstances but has not been definitively proven to protect the nerve any more effectively than the gold standard of nerve visualization. In our study, the use of IONM did not reduce the time of thyroid surgery and did increase the cost. While IONM may, in special clinical circumstances such as revision and malignant thyroid surgery, increase the value of the operation, its use for every thyroid surgery does not appear to be cost effective or valuable to the patient.

Axillary metastases from occult breast cancer. Our experience.

We report the case of a 63-year-old woman with occult breast cancer who presented with a hard metastatic nodule in the left axilla. Although histology identified a metastatic carcinoma in the lymph nodes, numerous tests failed to detect the primary tumor. Resected lymph node was positive for both estrogen and progesterone receptors, suggesting the breast as the site of the primary tumor. Left modified radical mastectomy was performed. Pathology revealed an invasive lobular carcinoma (2.5 x 2 mm in size) with extensive lymphatic involvement, which strongly expressed both vascular endothelial growth factor-C (VEGF-C) and VEGF-D.

Male breast cancer in the twenty-first century: What's new?

Male breast cancer is an uncommon disease although the incidence has increased over the past 25 years. As with many other rare "orphan" diseases, male breast cancer is understudied. The rarity of the disease precludes prospective randomized clinical trials. In addition, few researchers and minimal funding have focused on breast cancer in men, but further work is clearly needed to better understand this disease. It shares many similarities with breast cancer in women; yet some clear differences have emerged. In this article, the latest information on the epidemiology, biology, and treatment of male breast cancer is reviewed. KEY WORDS: Epidemiology, Male breast cancer, Prognosis, Treatment.

Metaplastic carcinoma of the breast: Treatment, results and prognostic factors based on international literature.

Metaplastic carcinoma of the breast (MCB) is a rare form of cancer containing mixture of epithelial and mesenchymal elements in variable combinations. Few and conflicting clinical data are available in the literature addressing optimal treatment modalities, prognosis and outcome. A retrospective study was conducted to review all patients with MCB diagnosed and treated at Breast Unit of Azienda Ospedaliera "Santa Maria" Terni - Italy between 2001/2010. The aim is to describe patient's clinic pathologic features and to analyze treatment results. Six female patients were studied. The median age was 48 years (range 14/58). The median tumor size was 9 cm. (range 3/18 cm.). Two cases (33%) were identified as purely epithelial and 4 (67%) as mixed epithelial and mesenchymal metaplasia. Hormone receptors were positive in only 2 patients. Modified radical mastectomy performed in 3 patients and 5 underwent axillary node dissection. Adjuvant chemotherapy was given to all patients and postoperative radiotherapy to 4. Four patients relapsed with median time of relapse of 12 months. MCB is an aggressive form of breast cancer associated with poor outcome, high incidence of local recurrence and pulmonary metastases. The disease tends to be estrogen/progesterone receptor negative. Tumor size has an important impact on outcome. The best treatment approach is yet to be defined.

Breast metastasis from a pulmonary adenocarcinoma: Case report and review of the literature.

Breast metastasis from extra-mammary malignancy is rare. An incidence of 0.4-1.3% has been reported in the literature. The primary malignancies most commonly metastasizing to the breast are leukemia, lymphoma and malignant melanoma. We present a case of metastasis to the breast from a pulmonary adenocarcinoma, diagnosed concomitantly with the primary tumor. A 43-year-old female presented with dyspnea and a dry cough of 3 weeks' duration. A subsequent chest radiograph revealed a massive pleural effusion. Additionally, on physical examination, a poorly defined mass was noted in the upper outer quadrant of the right breast. The patient underwent bronchoscopy, simple right mastectomy and medical thoracoscopy. Following cytology, histology and immunohistochemistry, primary lung adenocarcinoma with metastasis to the breast and parietal pleura was diagnosed. Histologically, both the primary and metastatic anatomic sites demonstrated a micropapillary component, which has recently been recognized as an important prognostic factor. Although the patient received chemotherapy, she succumbed to her condition within 8 months. Accurate differentiation of metastasis from primary carcinoma is very important as the treatment and prognosis of the two differ significantly.

A rare breast tumor: solid neuroendocrine carcinoma.

BACKGROUND: Solid neuroendocrine carcinoma of breast (NECB) is extremely rare. In this paper, we present a case of inflammatory primary solid neuroendocrine carcinoma of breast managed by surgery and chemotherapy and a brief review of the epidemiology, clinical features, diagnosis, pathologic features, treatment, and prognosis of solid NECB. METHODS: A 63-year-old woman was admitted in our institution with inflammatory primary solid neuroendocrine carcinoma of breast. A bulky mass of 6,5 cm tumor was located in the upper-outer and intern quadrant of her right breast. The patient underwent neo-adjuvant chemotherapy, and subsequent radical mastectomy with axillary lymph node dissection. Microscopically, the tumor was classified as solid cohesive, the tumor cells were positive for neuroendocrine markers chromogranin A and synaptophysin. 19 lymph nodes of 27 were metastatic. RESULTS: Local recurrence and metastatic progression was noted only one month after the surgery, the patient was managed by chemotherapy and hormone-therapy. She is still alive, 24 months after diagnosis. CONCLUSIONS: Solid neuroendocrine carcinoma is a subtype of mammary carcinoma with several distinctive features. Because of the rarity of this disease, there is no standard treatment, they are characterized by a higher propensity for local and distant recurrence, This case reinforces the importance to explore the novels therapeutics regimen and one of ways to explore is the use of VP16-cisplatine as treatment as it was partially efficacy for this kind of tumor.

Cystosarcoma phyllodes with muscular and lymph node metastasis. Our experience and review of the literature.

BACKGROUND: Phyllodes tumors are biphasic fibroepithelial neoplasms of the breast. While the surgical management of these relatively uncommon tumors has been addressed in the literature, few reports have commented on the surgical approach to tumors greater than ten centimeters in diameter - the giant phyllodes tumor. CASE REPORT: We report a case of a 45-year-old woman who presented with a large lump in her right breast, involvement of multiple ipsilateral axillary lymph nodes and pectoralis major muscle. Clinical findings and cytologic examination (fine-needle aspiration) were suggestive of cystosarcoma phyllodes and we discuss the techniques utilized for pre-operative diagnosis, tumor removal, and breast reconstruction. A review of the literature on the surgical management of phyllodes tumors was performed. CONCLUSION: Management of the phyllodes tumor presents the surgeon with unique challenges. The majority of these tumors can be managed by simple mastectomy. In our case clinical findings and cytologic examination (fine-needle aspiration) were suggestive of cystosarcoma phyllodes, for which the patient underwent a modified radical mastectomy. Postoperative radio therapy was given to the loco regional area. KEYWORDS: Immediate reconstruction, Phylloides tumors, Post-operative radio therapy, Radical surgery.
