RESUMO
BACKGROUND: The initial results of the SINODAR-ONE randomized clinical trial reported that patients with T1-2 breast cancer and one to two macrometastatic sentinel lymph nodes treated with breast-conserving surgery, sentinel lymph node biopsy only, and adjuvant therapy did not present worse 3-year survival, regional recurrence, or distant recurrence rates compared with those treated with axillary lymph node dissection. To extend the recommendation of axillary lymph node dissection omission even in patients treated with mastectomy, a sub-analysis of the SINODAR-ONE trial is presented here. METHODS: Patients with T1-2 breast cancer and no more than two metastatic sentinel lymph nodes undergoing mastectomy were analysed. After sentinel lymph node biopsy, patients were randomly assigned to receive either axillary lymph node dissection followed by adjuvant treatment (standard arm) or adjuvant treatment alone (experimental arm). The primary endpoint was overall survival. The secondary endpoint was recurrence-free survival. RESULTS: A total of 218 patients were treated with mastectomy; 111 were randomly assigned to the axillary lymph node dissection group and 107 to the sentinel lymph node biopsy-only group. At a median follow-up of 33.0 months, there were three deaths (two deaths in the axillary lymph node dissection group and one death in the sentinel lymph node biopsy-only group). There were five recurrences in each treatment arm. No axillary lymph node recurrence was observed. The 5-year overall survival rates were 97.8 and 98.7 per cent in the axillary lymph node dissection treatment arm and the sentinel lymph node biopsy-only treatment arm, respectively (P = 0.597). The 5-year recurrence-free survival rates were 95.7 and 94.1 per cent in the axillary lymph node dissection treatment arm and the sentinel lymph node biopsy treatment arm, respectively (P = 0.821). CONCLUSION: In patients with T1-2 breast cancer and one to two macrometastatic sentinel lymph nodes treated with mastectomy, the overall survival and recurrence-free survival rates of patients treated with sentinel lymph node biopsy only were not inferior to those treated with axillary lymph node dissection. To strengthen the conclusion of the trial, the enrolment of patients treated with mastectomy was reopened as a single-arm experimental study. REGISTRATION NUMBER: NCT05160324 (http://www.clinicaltrials.gov).

Purpose: In modern breast cancer treatment, a growing role has been observed for breast reconstruction together with an increase in clinical indications for postmastectomy radiotherapy (PMRT). Choosing the optimum type of reconstructive technique is a clinical challenge. We therefore conducted a national multicenter study to analyze the impact of PMRT on breast reconstruction. Methods: We conducted a retrospective case-control multicenter study on women undergoing breast reconstruction. Data were collected from 18 Italian Breast Centres and stored in a cumulative database which included the following: autologous reconstruction, direct-to-implant (DTI), and tissue expander/immediate (TE/I). For all patients, we described complications and surgical endpoints to complications such as reconstruction failure, explant, change in type of reconstruction, and reintervention. Results: From 2001 to April 2020, 3116 patients were evaluated. The risk for any complication was significantly increased in patients receiving PMRT (aOR, 1.73; 95% CI, 1.33-2.24; p < 0.001). PMRT was associated with a significant increase in the risk of capsular contracture in the DTI and TE/I groups (aOR, 2.24; 95% CI, 1.57-3.20; p < 0.001). Comparing type of procedures, the risk of failure (aOR, 1.82; 95% CI, 1.06-3.12, p=0.030), explant (aOR, 3.34; 95% CI, 3.85-7.83, p < 0.001), and severe complications (aOR, 2.54; 95% CI, 1.88-3.43, p < 0.001) were significantly higher in the group undergoing DTI reconstruction as compared to TE/I reconstruction. Conclusion: Our study confirms that autologous reconstruction is the procedure least impacted by PMRT, while DTI appears to be the most impacted by PMRT, when compared with TE/I which shows a lower rate of explant and reconstruction failure. The trial is registered with NCT04783818, and the date of registration is 1 March, 2021, retrospectively registered.

BACKGROUND: The SINODAR-ONE trial is a prospective noninferiority multicenter randomized study aimed at assessing the role of axillary lymph node dissection (ALND) in patients undergoing either breast-conserving surgery or mastectomy for T1-2 breast cancer (BC) and presenting one or two macrometastatic sentinel lymph nodes (SLNs). The endpoints were to evaluate whether SLN biopsy (SLNB) only was associated with worsening of the prognosis compared with ALND in terms of overall survival (OS) and relapse. METHODS: Patients were randomly assigned (1:1 ratio) to either removal of ≥ 10 axillary level I/II non-SLNs followed by adjuvant therapy (standard arm) or no further axillary treatment (experimental arm). RESULTS: The trial started in April 2015 and ceased in April 2020, involving 889 patients. Median follow-up was 34.0 months. There were eight deaths (ALND, 4; SNLB only, 4), with 5-year cumulative mortality of 5.8% and 2.1% in the standard and experimental arm, respectively (p = 0.984). There were 26 recurrences (ALND 11; SNLB only, 15), with 5-year cumulative incidence of recurrence of 6.9% and 3.3% in the standard and experimental arm, respectively (p = 0.444). Only one axillary lymph node recurrence was observed in each arm. The 5-year OS rates were 98.9% and 98.8%, in the ALND and SNLB-only arm, respectively (p = 0.936). CONCLUSIONS: The 3-year survival and relapse rates of T1-2 BC patients with one or two macrometastatic SLNs treated with SLNB only, and adjuvant therapy, were not inferior to those of patients treated with ALND. These results do not support the use of routine ALND.

BACKGROUND: Gynecomastia is the most common form of breast alteration in men, due to proliferation of the gland ducts and stromal components, including fat. In addition to the most obvious indications (weight loss, pharmacotherapy, and drugs suspension), the surgical treatment is needed for long-standing gynecomastia, combining liposuction, adenectomy, partial mammary adenectomy, periareolar skin resection, and round-block suture. MATERIALS AND METHODS: A retrospective study was conducted on 148 patients undergoing gynecomastia correction from May 2012 to April 2018. Follow-up ranged from 9 to 14 months. The authors propose a new ultrasound-confirmed classification system, dividing patients into six categories. The authors analyzed immediate complications, revision, recurrence, and minor aesthetic problems (retracted/depressed areas) and introduced a way to correct the irregularities with fat grafting and needles. RESULTS: The total complication rate was 11.5% (17/148). Most of the complications (11) were observed in patients who underwent glandular resection and 3 after liposuction only. Retrospective surveys about patients' and surgeons' satisfaction were performed, showing excellent feedbacks regarding the results accomplished. CONCLUSIONS: The simple classification helps surgeons choose the most suitable approach, avoiding insufficient or invasive treatments and undesirable scars. Moreover, the analysis of the type of sequelae and their correction allow high patients' satisfaction.

BACKGROUND: Due to its rarity, male breast cancer (mBC) remains an inadequately characterized disease, and current evidence for treatment derives from female breast cancer (FBC). METHODS: We retrospectively analyzed the clinicopathological characteristics, treatment patterns, and outcomes of mBCs treated from 2000 to 2013. RESULTS: From a total of 97 patients with mBC, 6 (6.2%) with ductal in situ carcinoma were excluded, and 91 patients with invasive carcinoma were analyzed. Median age was 65 years (range: 25-87 years). Estrogen receptors were positive in 88 patients (96.7%), and progesterone receptors were positive in 84 patients (92.3%). HER-2 was overexpressed in 13 of 85 patients (16%). Median follow-up was 51.5 months (range: 0.5-219.3 months). Five-year progression-free survival (PFS) was 50%, whereas overall survival (OS) was 68.1%. Patients with grades 1 and 2 presented 5-year PFS of 71% versus 22.5% for patients with grade 3 disease; 5-year OS was 85.7% for patients with grades 1 and 2 versus 53.3% of patients with grade 3. Ki-67 score >20% and adjuvant chemotherapy were also statistically significant for OS on univariate analyses. Twenty-six of 87 patients (29.8%) experienced recurrent disease and 16 of 91 patients (17.6%) developed a second neoplasia. CONCLUSION: Male breast cancer shows different biological patterns compared with FBC, with higher positive hormone-receptor status and lower HER-2 overexpression. Grade 3 and Ki-67 >20% were associated with shorter OS. IMPLICATIONS FOR PRACTICE: There is little evidence that prognostic features established in female breast cancer, such as grading and Ki-67 labeling index, could be applied to male breast cancer as well. This study found that grade 3 was associated with shorter overall survival and a trend for Ki-67 >20%; this could help in choosing the best treatment option in the adjuvant setting. Many questions remain regarding the impact of HER-2 positivity on survival and treatment with adjuvant anti-HER-2 therapy. Regarding metastatic male breast cancer, the results suggest that common regimens of chemo-, endocrine and immunotherapy used in female breast cancer are safe and effective for men. Male breast cancer patients show a higher incidence of second primary tumors, especially prostate and colon cancers and should therefore be carefully monitored.

Phyllodes tumor is an extremely rare tumor of the breast. It occurs in females in the third and fourth decades. The difficulty in distinguishing between phyllodes tumors and benign fibroadenoma may lead to misdiagnosis. Lymph node involvement is rarely described in phyllodes tumors; for this reason, sentinel node biopsy may be warranted. We present a case of a 33-year-old woman affected by huge tumor of the right breast with ulceration in the skin with a rapid tumor growth and with omolateral axillary metastasis.

Background: Postoperative seroma is most frequent after mastectomy (ME) in combination with axillary lymph node dissection (ALND), and its reported incidence varies from 15.5% up to 90%. Seromas can be responsible for discomfort, infections and can lead to reconstruction failure. Therefore, many ways of seroma prevention have been studied, although from a recent overview it has become clear that no single method is reliably successful. Mechanical closure of the dead space, however, was consistently found to be significantly effective. The aim of our study is to evaluate if quilting of the axilla, in patients undergoing ME, immediate prosthetic breast reconstruction and ALND reduces the duration of drain maintenance, the incidence of seromas that require aspiration (clinically significant seromas, CSS) and reconstruction failure rate. Materials and methods: In our study population we analyzed a total of 81 patients divided into two groups: 27 consecutive patients undergoing mastectomy, axillary lymph node dissection (ALND), breast reconstruction and quilting of the axilla. We subsequently randomly picked up a double number of patients (54) undergoing the same oncological and reconstructive procedures without undergoing axillary quilting, matched for clinical characteristics in order to analyze efficacy of the procedure while reducing any bias. Our observational retrospective data was collected from October 2016 to July 2020 in one single high-volume center. Our median follow-up time was of 40.6 months. Results: In the case group we observed a reduced time of drain maintenance: 16 vs. 20 days observed in the non-quilted group (p < 0.05). Incidence of seromas that required aspiration was 11% in the control group, while 3,7% in the case group. In addition to that, we observed 6 cases of implant removal in the control group, while in the quilted group we only observed a single case. Conclusion: Previous literature and our results confirm that quilting of the axilla with flap fixation significantly decreases time of drain maintenance, allowing the earlier removal of the drains as well as decreasing the incidence of seroma, its eventual associated complications and related social costs. Moreover, our work suggests how quilting sutures decrease the incidence of seroma in patients undergoing immediate reconstruction, probably reducing the risk for implant removal.
RESUMO
Video assisted thoracic surgery (VATS) lobectomy is the treatment of choice for early-stage lung cancer. It is safe and effective compared to open surgery, as demonstrated by a large body of scientific evidence over the last few decades. VATS lobectomy's evolution was driven by the need to decrease post-operative pain by reducing the extent of surgical accesses, maintaining the same oncological efficacy of open lobectomy with less invasiveness. VATS lobectomy just turned 30 years old, evolving and changing significantly from its origins. The aim of this mini review is to retrace the history, starting from a multiport approach to a single port approach. At the end of this mini review, we will discuss the advanced and the future challenges of the technique that has revolutionized thoracic surgery.
RESUMO
BACKGROUND: The identification of small lung nodules is challenging during mini-invasive thoracic surgery. Unable to palpate them directly, surgeons have developed several methods to preoperatively localize pulmonary nodules, including the computed tomography-guided positioning of coils or metallic landmarks (hook wire) or bronchoscopic marking. METHODS: We present a series of patients scheduled for the video-assisted thoracoscopic sublobar resection of small pulmonary nodules, in which we performed preoperative percutaneous computed tomography (CT)-guided nodule localization through the injection of a mixture of indocyanine green and human albumin. RESULTS: A total of 40 patients underwent a preoperative CT-guided injection of indocyanine green followed by VATS resection within 24 h. Patients tolerated the procedure well, no pain medication was administrated, and no complications were observed during the marking procedure. All pulmonary nodules were easily detected and successfully resected. CONCLUSION: the near-infrared dye marking solution of indocyanine green (ICG) with diluted human albumin was safe, effective, and easy to perform. The ICG solution has the potential to facilitate the accurate localization and resection of pulmonary nodules during VATS surgery, avoiding the risk of marker displacement/migration.
RESUMO
BACKGROUND: Intraoperative localisation of nodal disease in non-small cell lung cancer (NSCLC) can be challenging. Lymph node localisation via radiopharmaceuticals is used in many conditions; we tested the feasibility of this approach in NSCLC. METHODS: NSCLC patients were prospectively recruited. Intraoperative peri-tumoral injections of [99mTc]Tc-albumin nanocolloids were performed, followed by removing the tumour and locoregional lymph nodes. These were examined ex vivo with a gamma probe and labelled sentinel lymph nodes (SLNs) if they showed any activity or non-sentinel lymph nodes (nSLNs) if they did not. Thereafter, the surgical field was scanned with the probe; any further radioactive lymph node was removed and labelled as "extra" SLNs (eSLNs). All specimens were sent to histology, and metastatic status was recorded. RESULTS: 48 patients were enrolled, and 290 nodal stations were identified: 179 SLNs, 87 nSLNs, and 24 eSLNs. A total of 44 nodal metastases were identified in 22 patients, with 36 of them (82%) located within SLNs. Patients with nSLNs metastases had at least a co-existing positive SLN. No metastases were found in eSLNs. CONCLUSIONS: The technique shows high sensitivity for intraoperative nodal metastases identification. This information could allow selective lymphadenectomies in low-risk patients or more aggressive approaches in high-risk patients.
RESUMO
Despite the adoption of enhanced recovery programs, the reported postoperative length of stay after robotic surgery is 4 days even in highly specialized centers. We report preliminary results of a pilot study for a new protocol of early discharge (on day 2) with telehealth home monitoring after robotic lobectomy for lung cancer. All patients with a caregiver were discharged on postoperative day 2 with a telemonitoring device if they satisfied specific discharge criteria. Teleconsultations were scheduled once in the afternoon of post-operative day 2, twice on postoperative day 3, and then once a day until the chest tube removal. Post-discharge vital signs were recorded by patients at least four times daily through the device and were available for consultation by two surgeons through phone application. In case of sudden variation of vital signs or occurrence of adverse events, a direct telephone line was available for patients as well as a protected re-hospitalization path. Primary outcome was the safety evaluated by the occurrence of post-discharge complications and readmissions. Secondary outcome was the evaluation of resources optimization (hospitalization days) maintaining the standard of care. During the study period, twelve patients satisfied all preoperative clinical criteria to be enrolled in our protocol. Two of twelve enrolled patients were successively excluded because they did not satisfy discharge criteria on postoperative day 2. During telehealth home monitoring a total of 27/427 vital-sign measurements violated the threshold in seven patients. Among the threshold violations, only 1 out of 27 was a critical violation and was managed at home. No postoperative complication occurred neither readmission was needed. A mean number of three hospitalization days was avoided and an estimated economic benefit of about EUR 500 for a single patient was obtained if compared with patients submitted to VATS lobectomy in the same period. These preliminary results confirm that adoption of telemonitoring allows, in selected patients, a safe discharge on postoperative day 2 after robotic surgery for early-stage NSCLC. A potential economic benefit could derive from this protocol if this data will be confirmed in larger sample.
RESUMO
BACKGROUND: The aim of this pilot trial was to study the feasibility of sentinel node percutaneous preoperative gamma probe-guided biopsy as a valid preoperative method of assessment of nodal status compared to surgical sentinel lymph node biopsy. MATERIAL/METHODS: This prospective study enrolled 10 consecutive patients without evidence of axillary lymph node metastases at preoperative imaging. All patients underwent sentinel node occult lesion localization (SNOLL) using radiotracer intradermic injection that detected a "hot spot" corresponding to the sentinel node in all cases. Gamma probe over the skin detection with subsequent ultrasonographically guided needle biopsy of the sentinel node were performed. The percutaneous needle core histopathological diagnosis was compared to the results of the surgical biopsy. RESULTS: Preoperative sentinel node identification was successful in all patients. CONCLUSIONS: The combination of preoperative gamma probe sentinel node detection and ultrasound-guided biopsy could represent a valid alternative to intraoperative sentinel node biopsy in clinically and ultrasonographically negative axillary nodes, resulting in shorter duration of surgery and lower intraoperative risks.

Pulmonary metastasectomy is an established treatment that can provide improved long- term survival for patients with metastatic tumor(s) in the lung. In this mini-review, we discuss the state of the art of thoracic surgery in surgical management of lung metastases which actually occurs for a large part of surgical activity in thoracic surgery department. We describe the principles of surgical therapy that have been defined across the time, and that should remain the milestones of lung metastases treatment: a radical surgery and an adequate lymphadenectomy. We then focus on current surgical indications and report the oncological results according to the surgical approach (open vs. mini-invasive), the histological type and number of lung metastases, and in case of re-metastasectomy. Finally, we conclude with a brief overview about the future perspectives in thoracic surgery in treatment of lung metastases.
RESUMO
Lung cancer (LC) is the second most commonly diagnosed cancer and the primary cause of cancer death worldwide in 2020. LC treatment is associated with huge costs for patients and society; consequently, there is an increasing interest in the prevention, early detection with screening, and development of new treatments. Its surgical management accounts for at least 90% of the activity of thoracic surgery departments. Surgery is the treatment of choice for early-stage non-small cell LC. In this article, we discuss the state of the art of thoracic surgery for surgical management of LC. We start by describing the milestones of LC treatment, which are lobectomy and an adequate lymphadenectomy, and then we focus on the traditional and innovative minimally invasive surgical approaches available: video-assisted thoracoscopic surgery (VATS) and robotic-assisted thoracoscopic surgery (RATS). A brief overview of the innovation and future perspective in thoracic surgery will close this mini-review.
RESUMO
The use of extracorporeal lung support (ECLS) during thoracic surgery is a recent concept that has been gaining increasing approval. Firstly introduced for lung transplantation, this technique is now increasingly adopted also in oncological thoracic surgical procedures. In this review, we focus on the cutting-edge application of extracorporeal membrane oxygenation (ECMO) during oncological thoracic surgery. Therefore, we report the most common surgical procedures in oncological thoracic surgery that can benefit from the use of ECMO. They will be classified and discussed according to the aim of ECMO application. In particular, the use of ECMO is usually limited to certain lung surgery procedures that can be resumed such as in procedures in which an adequate ventilation is not possible such as in single lung patients, procedures where conventional ventilation can cause conflict with the surgical field such as tracheal or carinal surgery, and conventional procedures requiring both ventilators and hemodynamic support. So far, all available evidence comes from centers with large experience in ECMO and major thoracic surgery procedures.
RESUMO
BACKGROUNDS: Since the application of mini-invasive surgery to pulmonary lobectomy, various studies confirmed the feasibility and the safety of the technique, with equivalent oncological standards. However, there are no studies that compare long-term postoperative pain in minimally invasive thoracic surgery. METHODS: Between 1 January 2019 and 28 February 2020, we analysed pain scores at 2 weeks, 3 months, 6 months, and 1 year after the operation, where 50 patients underwent a VATS lobectomy and 50 underwent a RATS lobectomy. Pain scores are obtained through a telephone questionnaire, according to a Numerical Rating Scale (NRS). RESULTS: The medias of the NRS scores, at 2 weeks, 3 months, 6 months, and 1 year after the operation were similar in both groups. Group I was composed of 50 patients who underwent a video-assisted lobectomy, while Group II was composed of 50 patients who underwent a robotic-assisted lobectomy. Two weeks after surgery Group I had a NRS value of 2.96 and in Group II it was 2.86; three months after in Group I the value was 2.16 and in Group II it was 2.06; six months after Group I 's value was 1.62 and Group II's was 1.56; one year after in Group I the value was 1.30 and in the Group II was 1.24. For each time interval, no statistically significant differences were found (p > 0.05). CONCLUSIONS: In our analysis, RATS and VATS did not have significant differences in post-operative and long-term pain.
RESUMO
Localization of small-sized pulmonary nodules is challenging during video-assisted thoracoscopic surgery. Several preoperative strategies have been developed to mark these targets. We describe our localization strategy using a preoperative computed tomography-guided near-infrared dye marking.
RESUMO
Objectives: We examined a series of malignant pleural mesothelioma (MPM) patients who consecutively underwent surgery in our institution during the last 20 years. Across this period, we changed our surgical approach to MPM, adopting extended pleurectomy and decortication (eP/D) instead of extrapleural pneumonectomy (EPP). In this study, we compare the perioperative outcomes and long-term survival of patients who underwent EPP vs. eP/D. Methods: A retrospective analysis was carried out of all the MPM patients identified from our departmental database who underwent EPP or P/D from 2000 to 2021. Clavien−Dindo criteria was adopted to score postoperative complications, while Kaplan−Meier methods and a Cox multivariable analysis were used to perform the survival analysis. Results: Of 163 patients, 78 (48%) underwent EPP and 85 (52%) eP/D. Induction chemotherapy was significantly administrated more often in the eP/D group (88% vs. 51%). Complete trimodality treatment including induction chemotherapy, radical surgery, and adjuvant radiotherapy was administered in 74% of the eP/D group versus 32% of the EPP group (p < 0.001). The postoperative morbidity rate was higher in the eP/D group (54%) compared to the EPP group (36%) (p = 0.02); no statistically significant differences were identified concerning major complications (EPP 43% vs. eP/D 24%, p = 0.08). No statistical differences were identified in 30-day mortality, 90-day mortality, median disease-free, and overall survival statistics between the two groups. The Cox multivariable analysis confirmed no induction chemotherapy (HR, 0.5; p = 0.002), RDW (HR, 1.08; p = 0.02), and the presence of pathological nodal disease (HR, 1.99; p = 0.001) as factors associated with worse survival in the entire series. Conclusions: Our data support that eP/D is a well-tolerated procedure allowing the implementation of a trimodality strategy (induction chemotherapy, surgery, and radiotherapy) in most MPM patients. When eP/D is offered in this setting, the oncological results are comparable to EPP. To obtain the best oncological results, the goal of surgical resection should be macroscopic complete resection (R0) in carefully selected patients (clinical N0).
