Superomedial pedicle skin-reducing mastectomy in ptotic and large-sized breasts with two-stage reconstruction through transaxillary video-assisted technique: An effective surgical and anesthetic approach.

Introduction: Skin-reducing mastectomy has been applied to several surgical techniques in which subcutaneous mastectomy is associated with various types of skin reduction, with preservation of a lower dermal flap to reinforce the inferior lateral seat of an implant. The aim of the study is to present a case series of patients with pendulous/ptotic and/or large-sized breasts treated for breast cancer at the Breast Surgery Unit of Istituto Nazionale Tumori IRCCS Fondazione "G. Pascale", Naples, Italy, with the superomedial pedicle skin-reducing mastectomy technique, two-stage reconstruction, and transaxillary video-assisted technique, when a postoperative radiotherapy was indicated. We verified its effectiveness by discussing its results, especially in patients who are candidates for postmastectomy radiotherapy. Materials and methods: A single-center retrospective study was performed between January 2020 and March 2021 on a prospectively filled database of conservative mastectomies. Of the 64 patients who underwent nipple/skin-sparing mastectomies in the mentioned period, 17 (mean age 46 years, range 30-62 years) were treated with superomedial pedicle skin-reducing mastectomy, with two-stage breast reconstruction through transaxillary video-assisted replacement expander with definitive prosthesis and contralateral symmetrization, selected for postmastectomy radiotherapy. Results: We had only three minor complications. No flap necrosis, no infections, no breast seromas, and no reconstructive failures were observed. During follow-up of the patients treated with video-assisted reconstruction, there were no cases of infection, hematoma, implant rupture, or suture dehiscence in the reconstructed breast. Discussion: Skin-reducing mastectomy with superomedial pedicle is a safe and reliable procedure to treat breast cancer in selected patients, i.e., those with pendulous/ptotic and or large-sized breasts. Particularly, in patients who undergo postmastectomy radiotherapy, the two-stage reconstruction with video-assisted transaxillary endoscopic approach can find its main indication, using incisions positioned far from the mammary region, offering numerous advantages.

The number of excised lymph nodes is associated with survival of melanoma patients with lymph node metastasis.

BACKGROUND: Although the number of excised LNs has been associated with patient prognosis in many solid tumors, this association has not been widely investigated in cutaneous melanoma. This study aims to evaluate the association between the number of excised regional lymph nodes (LNs) and melanoma-specific survival. PATIENT AND METHODS: Clinico-pathological data from 2507 patients with LN metastasis treated at nine Italian centers were retrospectively collected. RESULTS: The number of excised LNs correlated with younger age (P < 0.001), male sex (P < 0.001), neck LN field (P < 0.001), LN micrometastasis (P < 0.001) and number of positive LNs (P < 0.001). The number of excised LNs was an independent prognostic factor (HR = 0.85; P = 0.002) after adjustment for other staging features. Upon subgroup analysis, the number of excised LNs had a significant prognostic value in patients bearing 1.01-2.00 mm (HR = 0.79; P = 0.032) and 2.01-4.00 mm (HR = 0.71; P < 0.001) thick melanomas, primary tumors showing ulceration (HR = 0.86; P = 0.033) and Clark level V of invasion (HR = 0.86; P = 0.010), LN micrometastasis (HR = 0.83; P = 0.014) and two to three positive LNs (HR = 0.71; P = 0.001). Finally, this study investigated the influence of the number of excised LNs on patient staging: only when ≥11 nodes were excised the AJCC N stage could stratify prognosis (P < 0.001). Considering the number of excised LNs for each lymphatic field, at least 14, 11, 10 and 12 LNs were needed to stage patients according to the AJCC N stage after a lymphadenectomy of the neck, axilla, inguinal and ilioinguinal LN fields, respectively. CONCLUSIONS: The number of excised LNs can be considered for risk stratification of patients with regional LN metastasis from cutaneous melanoma. We demonstrated that a minimum number of LNs is required for the correct staging of patients. Further research is needed to evaluate the effectiveness of the minimum number of LNs to be dissected.

Electrochemotherapy as "new standard of care" treatment for cutaneous Kaposi's sarcoma.

BACKGROUND: Electrochemotherapy (ECT) is a novel modality for the treatment of skin nodules and cutaneous or subcutaneous tumors that allows delivery of low and non-permeant drug into cells. The aim of this prospective single-center study was to evaluate ECT efficacy in the local treatment of Classic Kaposi's sarcoma (CKS) skin localization stage I-II sec. Brambilla et al. METHODS: Nineteen consecutive patients affected by classic KS were included in this study. All patients underwent blood sampling and concurrent incisional biopsy for histological diagnosis and Kaposi's sarcoma related herpes virus 8 (HHV-8) molecular analysis. ECT treatment of KS cutaneous lesions were performed according to the European Standard Operating Procedures of Electrochemotherapy (ESOPE). The primary endpoint of the study was the evaluation of ECT efficacy in the treatment of KS skin nodules and the assessment of HHV-8 viral load in the peripheral blood following the ECT therapy. RESULTS: Complete response (CR) was observed in 14 (73.6%) patients after first ECT session, while 3 (15.7%) and 2 (10.5%) out of 19 patients received a second and a third ECT treatment, respectively. Clinical response dragged out the whole follow-up period that ranged between 6 and 31 months with a median of 16 months. CONCLUSIONS: Clinical management of CKS skin localizations still represents a challenging task for surgeons and oncologists. Therefore, according to this and other author's recent experiences, ECT is claimed to become the "new standard of care" as first line treatment strategy for stage I-II CKS patients.

Can high-resolution ultrasound avoid the sentinel lymph-node biopsy procedure in the staging process of patients with stage I-II cutaneous melanoma?

PURPOSE: The objective of our study was to define the diagnostic accuracy of high-resolution ultrasound (US) in detecting nodal involvement before sentinel lymph node biopsy (SLNB) in patients with cutaneous melanoma, to define the sonographic criteria used to assess nodal metastases, and to establish if high-resolution US can directly select patients to radical lymphadenectomy, sparing selective lymphadenectomy. MATERIALS AND METHODS: 623 patients underwent high-resolution US of the regional lymph nodes, 24 hours prior being submitted to the sentinel lymph node biopsy procedure. The US findings were compared with histological findings. RESULTS: In 14.7 % out of 122 excised lymph nodes, high-resolution US showed sonographic features consistent with malignant involvement before the surgical step. US scan sensitivity and specificity were 15 and 100 %, respectively, since positive and negative predictive values were 100 and 87 % respectively. CONCLUSION: US is an effective modality in the presurgical detection of subclinical deposits within sentinel lymph nodes. However, preoperative staging work-up with high-resolution US cannot substitute the SLNB, mainly because of low sensitivity due to missing many micrometastases.

Sentinel lymph node biopsy in atypical Spitz nevi: is it useful?

AIMS: The aim of this study was to evaluate the incidence of lymph node metastases in patients with atypical Spitz nevi (ASN) after sentinel lymph node biopsy (SLNB) and during follow-up, and to assess the diagnostic value of the surgical procedure. METHODS: At the National Cancer Institute of Naples, Italy, 40 patients with ASN underwent SLNB between 2003 and 2011. Medical records were reviewed and all slides of the primary tumours were retrieved, rendered separately, and assessed by four experienced dermatopathologists from two different academic institutions. Each member of the review panel assessed slides separately without recourse to medical notes and blinded to each others' diagnosis. All patients were treated with wide local excision and SLN biopsy according to the standard procedure. All cases were followed up to assess outcomes. RESULTS: The original diagnosis of ASN was confirmed in all 40 cases. No sentinel node positivity was recorded, and no patients developed nodal involvement during a median follow-up of 46 months (range 16-103). All patients were alive and without evidence of locoregional or distant relapse at time of review. CONCLUSIONS: In our experience, ASN were not associated with metastatic potential. Surgical staging procedures are not justified and careful clinical surveillance is adequate.

[Neck dissection for Head and Neck cancers: state of the art and classification]. / Dissezioni linfonodali del collo per tumori del distretto cervico-facciale: note introduttive e classificazione.

The purposes of this article are to review the history and evolution of neck dissections, including an update on node levels and their anatomical landmark. A number of classification systems were proposed and subsequently established for neck dissection procedures. The system most often employed was published in 1991 by the American Head and Neck Society and American Academy of Otolaryngology- Head and Neck Surgery and revised in 2002 and 2008. According to this classification, neck dissections are grouped into four broad categories: radical neck dissection (RND), modified radical neck dissection (MRND), selective neck dissection (SND) and extended neck dissection (ERND). The choice between different surgeries depends on type and site of head and neck tumor as well nodal involvement.

Cervical vagal schwannoma. A case report.

Schwannoma originating from the cervical vagus nerve is an extremely rare neoplasm. Vagal nerve schwannoma usually occurs between the third and fifth decades of life, it does not show sex predilection both sexes being equally affected and it most often presents as a painless, slow-growing, lateral neck mass. The treatment of choice is complete surgical excision with preservation of the neural pathway, when it is possible. These tumours, in fact, are almost always benign and a conservative surgical approach is emphasized by most of the Authors. A case of a cervical vagal schwannoma, in a 33-year old male with a previous medical history of malignant lymphoma, is described. The clinical features, diagnosis, management and pathological findings of cervical vagal schwannoma are discussed.

Impact of false-negative sentinel lymph node biopsy on survival in patients with cutaneous melanoma.

BACKGROUND AND OBJECTIVES: Sentinel lymph node biopsy is widely accepted as standard care in melanoma despite lack of pertinent randomized trials results. A possible pitfall of this procedure is the inaccurate identification of the sentinel lymph node leading to biopsy and analysis of a nonsentinel node. Such a technical failure may yield a different prognosis. The purpose of this study is to analyze the incidence of false negativity and its impact on clinical outcome and to try to understand its causes. METHODS: The Melanoma Data Base at National Cancer Institute of Naples was analyzed comparing results between false-negative and tumor-positive sentinel node patients focusing on overall survival and prognostic factors influencing the clinical outcome. RESULTS: One hundred fifty-one cases were diagnosed to be tumor-positive after sentinel lymph node biopsy and were subjected to complete lymph node dissection. Thirty-four (18.4%)patients with tumor-negative sentinel node subsequently developed lymph node metastases in the basin site of the sentinel procedure. With a median follow-up of 42.8 months the 5-year overall survival was 48.4% and 66.3% for false-negative and tumor-positive group respectively with significant statistical differences (P < .03). CONCLUSIONS: The sensitivity of sentinel lymph node biopsy was 81.6%, and a regional nodal basin recurrence after negative-sentinel node biopsy means a worse prognosis, compared with patients submitted to complete lymph node dissection after a positive sentinel biopsy. The evidence of higher number of tumor-positive nodes after delayed lymphadenectomy in false-negative group compared with tumor-positive sentinel node cases, confirmed the importance of an early staging of lymph nodal involvement. Further data will better clarify the role of prognostic factors to identify cases with a more aggressive biological behavior of the disease.

Merkel cell carcinoma: experience of 14 cases and literature review.

Merkel cell carcinoma is an aggressive skin cancer, with a significant incidence of locoregional lymphnode involvement, which requires timely diagnosis, adequate staging and aggressive therapy based essentially on surgical procedures. The aim of this study is to report our experience and to compare our results with literature findings, in order to discuss the role of the procedures adopted and their influence on prognosis. From July 1995 to April 2005, 14 patients were treated and followed-up for MCC in the National Cancer Institute of Naples. Tumor location was: buttocks (43%), extremities (36%) head (7%), unknown (14%). There were 7 Stage I, 5 Stage II and 2 Stage III patients. Surgical treatment consisted in wide excision (WE) in Stage I cases, WE and regional lymphadenectomy followed by radio- or chemo-therapy in Stage II and combined surgical and pre- and post-operative medical treatments in Stage III. Overall disease specific survival rate was 64% (median follow up 44 months). Recurrence occurred in 86% of Stage I and 20% of Stage II patients and involved, in 83.3% of Stage I patients, the lymph nodal draining basin. The treatment of recurrence implied surgery and radio or radiochemotherapy. Overall survival rate of recurrent patients was 57% (median follow-up 37.2 months). Due to the particular lymphotrophism of MCC, major care should be set on investigation and treatment of tumor lymph nodal draining basin. As long as the disease remains surgically manageable the prognosis for patients with MCC is favourable. The role of radio and chemotherapy is not yet assessed.

Age as predictor in patients with cutaneous melanoma submitted to sentinel lymph node biopsy.

AIMS: To analyse the age as prognostic factor exploring the melanoma database at the National Cancer Institute in Naples. METHODS: Three hundred and ninety-nine patients with cutaneous melanoma were treated with sentinel lymph node biopsy from 1996 to 2003 at the National Cancer Institute of Naples. The results were analysed with particular attention to the overall survival among patients younger or older than 50 years of age. RESULTS: No differences were recorded between the younger and older group in terms of the identification rate and incidence of metastases. The analyses of disease-free survival and overall survival showed a significantly more favourable outcome in younger patients. The 5-year overall survival and the 5-year disease free survival were 81.8% vs. 68.0% and 76.3% vs. 59.1% for the younger and older group, respectively. CONCLUSIONS: The results suggest that in the management of cutaneous melanoma, age might be considered as prognostic factor both for disease free survival and overall survival.

[Histophenotypical variants of squamous cell carcinoma of the skin]. / Varianti istofenotipiche di carcinoma squamocellulare della cute.

Cutaneous squamous cell carcinoma (SCC) is, in its most frequent presentation, a moderately aggressive neoplastic disease. It can, however, present in a moltitude of clinico-pathological variants, some of which are characterized by a more malignant attitude. It is important to determine which tumors, among the various histophenotypes, are high risk in order to establish the appropriate treatment and follow-up. Histologic subtype has been considered as a possible variable in determining the prognosis of cutaneous SCC. We report our experience with 3 cases of peculiar variants of cutaneous SCC.

[Role of lymphadenectomy in the treatment of Merkel-cell tumors in i and ii stages]. / Ruolo della linfoadenectomia nel trattamento del tumore a cellule di merkel in stadio i e ii.

Merkel cell carcinoma (MCC) is a rare, malignant skin cancer, exhibiting neuroendocrine differentiation, with a significant incidence of locoregional lymph nodal involvement (40%-73%). The accepted staging system classifies MCC as: stage I, localized skin disease; stage II, regional lymph node disease; stage III, metastatic disease. The clinical differentiation of stage I and II patients is difficult and understaging is frequent. Surgery, as first approach, represents the leading treatment for this neoplasm and, depending on stage consists in: local wide excision for stage I patients and local excision and lymphadenectomy for stage II. In our experience, lymphadenectomy, included in the initial treatment of all stage II patients, seemed to influence positively the prognosis. In comparing stage related recurrence and survival rates the results we obtained were better in stage II patients, where lymphadenectomy was included in the initial treatment than in stage I subjects, who received local excision alone as first treatment and lymphadenectomy as secondary treatment for nodal recurrence (overall recurrence rate 86% vs 20%, survival rate 71% vs 80% in stage I vs stage II patients). The performance of lymphadenectomy for stage I MCC could be reconsidered both for a more reliable staging of the disease and for a positive impact on recurrence and survival rates.

[The right inferior laryngeal nerve with a non-recurrent course]. / Il nervo laringeo inferiore destro a decorso non ricorrente.

Two cases of a right non-recurrent laryngeal nerve were encountered during the performance of 992 thyroid operations. In its abnormal non-recurrent course the nerve passes transversely from under the carotid sheat hand takes a position which is at right-angles to the normal recurrent laryngeal nerve.

[Cervico-mediastinal carcinoma of the parathyroid: report of a case]. / Carcinoma cervicomediastinico della paratiroide: report di un caso.

Parathyroid carcinoma is a rare malignancy. We report the case of a 66 years old man referred to our department for a large substernal goiter suspected as a thyroid cancer associated with severe hyperparathyroidism. After normalization of serum levels of calcemia, total thyroidectomy and subtotal parathyroidectomy was performed. Histopathology revealed a parathyroid cancer of 450 g.

Drainage in thyroid surgery: a prospective randomised clinical study.

Drainage in thyroid surgery is still an area of controversy. We analysed the results of a prospective randomised trial conducted in our institution in order to assess the utility of drainage after thyroid surgery. Sixty patients were entered into the study, thirty of whom were drained after surgery and thirty who received no drainage. The two groups were well matched with regard to most characteristics. There was no difference between the two groups in terms of early or late postoperative complications. We therefore conclude that, in our experience, drainage after uncomplicated thyroid surgery is of no benefit.

[Giant Spigelian hernia associated with inguinal hernia. Repair with polypropylene prosthesis]. / Ernia di Spigelio "gigante" associata ad ernia inguinale. Riparazione con protesi di polipropilene.

Spigelian or lateral ventral hernia is a rare pathology, representing about 2% of all abdominal wall hernias. This kind of hernia can be found in the area limited from the umbilicus and anterosuperior iliac spine, near the lateral edge of the rectus abdominis. The authors describe a rare case of "giant" Spigelian hernia related with homolateral direct inguinal hernia. A seventy-year-old and obese patient had a painless huge intumescence in the right side of periumbilical area, and besides--he had a homolateral direct inguinal hernia. Abdominal computerized tomography visualized a hernial gap, which diameter is larger than 7 cm, in pararectal subumbilical site and a wide herniated bowel in interaponeurotic site. This double hernial pathology has been treated in an only solution, placing an only subfascial polypropylene prosthesis, overlapping both hernial defects. The authors believe prosthetic "tension free" repair, previous suture of the defect, represents a gold standard in the treatment of Spigelian hernia. Such refined technique allows an effective repair especially when aponeurotic defect is out of size and/or is related with subsequent homolateral hernia, also allowing an early patient's rehabilitation.
