RESUMO
BACKGROUND: Large intrathoracic tumors may occasionally present with massive infiltration of the lung and chest wall that would require pneumonectomy and total removal of the rib cage to obtain radical surgical excision, but this operation carries a prohibitive risk of death for cardiopulmonary failure in the absence of adequate chest wall reconstruction. METHODS: We report here four consecutive cases of thoracopleuropneumonectomy (TPP) with en-bloc resection of the entire lung, chest wall, and diaphragm and immediate riblike reconstruction for recurrent thoracic sarcomas. Patients had undergone the initial thoracic surgical resection with curative intent 2-14 years before TPP. There was no postoperative mortality, and all patients were alive and free of disease 8-21 months after TPP. RESULTS: To our knowledge, this is the first report in the medical literature of such an extensive operation, demonstrating technical feasibility, tolerability, and efficacy of one-stage resection and reconstruction by a semirigid three-dimensional riblike prosthesis modeled on a human-derived aluminum cast. CONCLUSIONS: Selected patients with advanced low-intermediate thoracic sarcomas are the ideal candidates for this extreme procedure, to maximize the chance of long-term tumor control and possibly cure.

The use of routine ionizing imaging in identify and classify patients with dislocation or infection after surgery has some medical contraindication, in addition to risks associated with the ionizing load and elevated costs. A novel, less expensive and non-ionizing imaging technique, called infrared thermal imaging, can be proposed as a complementary method to routinely evaluate hip prosthesis patients and track their inflammation response following serious complications. Here we report a case of a total hip prosthesis which was dislocated during inpatient rehabilitation, and ultimately reduced without surgical procedure. During the process, routine clinical and radiographic diagnosis was complemented with an infrared examination. The infrared images were easy to take bedside, without direct contact with the area of surgery, and well tolerated. After the dislocation reduction, the thermal imaging procedure provided important feedbacks on the local inflammation, helping to exclude other complications such as the infections.

Pulmonary metastasectomy has become a well-established procedure for patients with certain types of solid tumors. Patients are usually scheduled for staged lung metastasectomy in case of primary tumor control, the absence of distant non-lung metastases, and when complete resection is achievable. Nodules are removed with precision resection in order to ensure radical resection with minimal margins; this technique permits good oncological results, preserving the surrounding pulmonary parenchyma and causing minimal distortion compared to staplers. When possible, anatomical resections should be avoided since they are not justified by real oncological advantages and, in the majority of cases, sacrifice too much healthy tissue, possibly leading to inoperability in the case of metachronous relapses. Thus, preserving the maximum amount of pulmonary parenchyma is crucial because repeated metastasectomies are possible and frequent, with no theoretical limits to the number of reinterventions. In our multidisciplinary board team, we support the role of pulmonary metastasectomy as a useful curative therapy, with acceptable morbidity and mortality, with indications to be discussed case-by-case.
RESUMO
INTRODUCTION: Surgical resection of pulmonary metastases has been associated with increased survival at 5 years for osteosarcoma, but limited information is available on long-term outcome, role of repeated metastasectomies, and surgical sequelae in a pediatric population. We analyzed a consecutive series of children, adolescents, and young adults (AYA) treated by repeated lung metastasectomies during a period >40 years to estimate the clinical benefit and potential cure rate of salvage surgery. METHODS: All patients who underwent lung metastasectomy for osteosarcoma at the IRCCS Istituto Ortopedico Rizzoli of Bologna, University of Modena, and IRCCS Istituto Nazionale Tumori of Milan from May 1973 to January 2014 were included. Overall survival (OS) at 20 years from the first metastasectomy was calculated. RESULTS: A total of 463 consecutive children and AYA were analyzed. Median age was 15.9 years (range 0.2-23.2 years) and median follow-up 18.6 years. The 5- and 20-year OS were 34.0% and 29.7% (95% CI 25.5-34.0%). Among the 138 (29.8%) alive patients, 42 (30.4%) had disease recurrence cured by repeated metastasectomies. Disease-free interval from primary tumor, number of metastases, and complete resection were the most relevant survival predictors at multivariable model analysis. DISCUSSION: The extended follow-up of this consecutive series shows that repeated lung metastasectomy can achieve a permanent cure when offered to properly selected patients with metastases from osteosarcoma.

BACKGROUND: Congenital Pulmonary Malformations (CPMs) are rare benign lesions potentially causing infective complications and/or malignant transformation, requiring surgery even when asymptomatic. CPMs are rare in adulthood but potentially detected at any age. There is not a consensus on the correct extent of resection in both adults and paediatrics. This retrospective multicentric study aims to identify the appropriate surgical resection to prevent the recurrence of the related respiratory symptoms. METHODS: Between 2010 and 2020, a total of 96 patients (adults and pediatrics) underwent surgery for CPMs in 4 centers. A 2:1 propensity score matching (considering sex and lesion side) was performed, identifying 2 groups: 50 patients underwent lobectomy (group A) and 25 sub-lobar resections (group B). Clinical and histopathological characteristics, early and late complications, and symptom recurrence were retrospectively analyzed and compared between the two groups by univariate and multivariate analysis. RESULTS: Patients who underwent lobectomy had a statistically significant lower rate of recurrence (4% vs. 24% of group B, p = 0.014) and a lower rate of intraoperative complications (p = 0.014). Logistic regression identified sub-lobar resection (p = 0.040), intra- and post-operative complications (p = 0.105 and 0.022),and associated developed neoplasm (p = 0.062) as possible risk factors for symptom recurrence after surgery. CONCLUSIONS: Pulmonary lobectomy seems to be the most effective surgical treatment for CPMs, guaranteeing the stable remission of symptoms and a lower rate of intra- and postoperative complications. To our knowledge, this is one of the largest studies comparing lobectomy and sub-lobar resections in patients affected by CPMs, considering the low incidence worldwide.
RESUMO
BACKGROUND: Three-dimensional (3D) vision systems are available for video-assisted thoracic surgery (VATS). It is unclear whether 3D-VATS is superior to bidimensional (2D) VATS systems. METHODS: We analyzed patients who received 3D-VATS (n = 171) or 2D-VATS (n = 228) lobectomy in a single institutional retrospective comparative study of 399 patients with resectable lung cancer conducted from June 2012 to December 2017. The operative and perioperative data were compared between the 2 groups. RESULTS: Operative time, length of hospital stay, number of dissected lymph nodes, and rate of postoperative complications were similar in both groups. In the 3D group, there was no conversion to thoracotomy for intraoperative major vascular injuries, while conversion to an open procedure for uncontrolled bleeding was recorded in 4 (1.7%) patients in the 2D group. Reoperation for hemostasis and/or aerostasis occurred in 6 (2.6%) patients of the 2D group (p = 0.04). CONCLUSION: Nonrandomized comparison of different surgical approaches is challenging. In our experience, 3D-VATS was safe and effective and offered excellent operative perception and sensitivity, enabling safer dissection of hilar structures. The 3D-VATS system helped skilled surgeons beyond the boundaries of more oncologically aggressive surgery.

Introduction: Osteosarcoma is the most common malignant bone tumor. It is currently treated with pre-and postoperative chemotherapy, associated with surgical resection of the tumor.Area covered: Relapses occur in about one in three patients presenting with localized disease, and three in four of those with metastases at diagnosis. Relapsing disease carries a very poor prognosis, with 5-year survival rates ranging between 13% and 40%.Expert opinion: Patients with unilateral lung involvement or solitary lung metastases and a recurrence-free interval (RFI) longer than 24 months have a better prognosis, and could be managed with surgical resection and close observation. Complete surgical resection of all sites of disease remains essential to survival: patients unable to achieve complete remission have a catastrophic overall survival rate. The role of second-line chemotherapy is not at all clear, and no controlled studies are available on this topic. It is worth considering for patients unable to achieve complete surgical remission, and those with multiple metastases and/or a RFI <24 months. Given their dismal prognosis, patients with multiple sites of disease not amenable to complete surgical resection should also be considered for innovative therapeutic approaches.

Dual-energy x-ray absorptiometry (DXA) can provide quantitative (bone mineral density, BMD) and qualitative (trabecular bone score, TBS) indexes of bone status, able to predict fragility fractures in most osteoporotic patients. A new qualitative index of bone strength, based on finite element analysis and named bone strain index (BSI), has been recently developed from lumbar DXA scan. We present the preliminary results about the BSI ability to predict a refracture in patients with fragility fractures. A total of 143 consecutive fractured patients with primary osteoporosis (121 females) performed a spine x-ray examination for the calculation of spine deformity index (SDI) and a DXA densitometry for BMD, TBS, and BSI at basal time and in the follow-up. A refracture was considered as a one-unit increase in SDI. For each unit increase of the investigated indexes, the hazard ratio of refracture, 95% confidence interval, p value, and proportionality test p value were for BSI 1.201, 0.982-1.468, 0.074, and 0.218; for lumbar BMD 0.231, 0.028-1.877, 0.170, and 0.305; and for TBS 0.034, 0.001-2.579, 0.126, and 0.518, respectively. BSI was the index predictive of refracture nearest to statistical significance. If confirmed, it may be used for a better risk assessment of osteoporotic patients.

A 71-year-old male former smoker was referred for worsening hemoptysis from a hilar left tumor without radiologic or bronchoscopic identification of the bleeding source. He underwent an urgent upper lobectomy extended to the pericardium and left phrenic nerve to control active bleeding. Histologic analysis revealed a malignant triton tumor, a rare aggressive subtype of malignant peripheral nerve sheath tumors. This is a case report of unusual pulmonary involvement associated with hemoptysis. Despite radical surgery and multimodal treatment with adjuvant chemotherapy the patient died of systemic dissemination 10 months after surgery, with a disease-free survival of 3 months.

The extra-pleural pneumonectomy (EPP) is a standardised surgical procedure born for pleural tuberculosis and later used in pleural cancer treatment, especially in malignant pleural mesothelioma (MPM). This systematic review aimed to focus on the actual overall EPP role in surgical oncology. The literature search was performed from January 1985 to January 2018 In PubMed, Embase, and Cochrane according to PRISMA protocol. The search was restricted to publications in English with the research words "extrapleural pneumonectomy", "malignant pleural mesothelioma", "pleural malignancies". The results were then filtered focusing only on papers with series of patients treated with EPP, for mesothelioma and non-mesothelioma malignancies. The search was restricted to publications in English. We found a 5-year overall survival (OS) ranging from 0 to 78%. The peri-operative mortality and morbidity ranged from 0 to 11.8% and 0 to 82.6%, respectively. The most represented and described post-operative complications reported were ARDS, pericardial tamponade, cardiac herniation, pulmonary embolism, respiratory infections, respiratory failure, atrial arrhythmia, myocardial infarction. In referral centres and selected patients, EPP is a cytoreductive or radical surgical treatment in extended pleural malignancies. Prospective studies are needed to standardise the timing of the procedure in a multimodality treatment program, according to the oncological and functional indications, to keep an acceptable complications rate and post-operative quality of life status.
RESUMO
BACKGROUND: Indeterminate non-calcified lung nodules are frequent when low-dose spiral computed tomography (LD-CT) is used for lung cancer screening. We assessed the diagnostic utility of a non-invasive work-up protocol for nodules detected at baseline in volunteers enrolled in our single-centre screening trial, and followed for at least 1 year. METHODS: 5201 high-risk volunteers, recruited over 1 year from October 2004, underwent baseline LD-CT; 4821 (93%) returned for the first repeat LD-CT. Nodules

Between 1998 and 2003 we observed 15 women who underwent full thickness chest wall resection (FTCWR) followed by plastic reconstruction for locally recurrent or primary breast cancer. Preoperative symptoms were: pain (5 patients), malodorous ulceration (3 patients), presence of tumour mass (4 patients) and thoracic deformity (2 patients). One patient was asymptomatic. Surgery was partial sternectomy with rib resection in 9 patients, rib resection alone in 5, and total sternectomy in one. No perioperative mortality or major morbidity occurred; minor complications occurred in 3 patients (20%). Five of the six surviving patients reported a positive overall outcome in a telephonic interview. Median overall and disease-free survival were 23.4 and 17.5 months, respectively. In conclusion, FTCWR is a safe procedure with low morbidity and mortality that can provide good symptoms palliation in patients with locally advanced breast malignancies, so it should be considered more often by interdisciplinary care providers in those patients who fail to respond to classic multimodality treatment.

OBJECTIVE: A higher mortality has been reported after pneumonectomy over the age of 70. The aim of the study was to quantify the additional risk due to age after standard pneumonectomy for lung cancer by a case-control study. METHODS: Our clinical database was reviewed to search for patients aged 70 years or more who underwent standard pneumonectomy for lung cancer between 1998 and 2005. A control group of patients younger than 70 (one case/two controls) was matched for sex, cardiovascular disease, American Association of Anaesthetists score, respiratory function, side of pneumonectomy, induction chemotherapy and stage. Overall mortality and morbidity were compared. Long-term survival data were also analysed. RESULTS: During the considered period, 35 patients aged 70 years or more underwent pneumonectomy (30 males, median age 73 years, 15 right-sided procedures). The control group was composed of 70 patients. The two groups were homogeneous in the variables used for matching. Overall mortality and morbidity were 11.4 and 54.2% in the elderly group as compared to 4.3 and 41.6% in controls (p-value not significant). Elderly patients experienced a higher rate of respiratory complications (25.7%) as compared to controls (8.3%, p=0.01). At univariate analysis, the only risk factor for death was the occurrence of respiratory complications (OR 6.5, CI 1.8-18.2). At multivariate analysis, age >or=70 years (OR 5.36, CI 1.48-19.3) and preoperative chemotherapy (OR 7.65, CI 2.04-28.6) were confirmed as predictors of respiratory complications. Five-year survival was 17.5% in the elderly group and 53.6% in the control group (p=0.003). Elderly patients with a better respiratory function (FEV1>70%) had a 5-year survival of 45.4%. CONCLUSIONS: In the elderly patients, the risk of respiratory complications after pneumonectomy is increased as compared to younger patients with equivalent respiratory function. Age and preoperative chemotherapy are independent risk factors for respiratory complications. A lower mortality and a better long-term survival are obtained in elderly patients with a better respiratory function (FEV1>or=70%).

Pulmonary metastasectomy has become a standard procedure for pediatric patients with certain types of solid tumors. Surgeons, expert pediatric oncologists and radiation oncologists contribute with their different skills to the management of pulmonary metastases. Patients are usually scheduled for surgery in case of primary tumor control, in absence of metastases in other organs and when a complete resection is achievable. Nodules are removed through precision resections using electrocautery or laser methods in order to ensure radical surgery with adequate margins. With these techniques, it is possible to preserve the surrounding parenchyma and cause a limited volumetric distortion as compared with staplers. Anatomical resections (segmentectomy, lobectomy or pneumonectomy) should be reserved for selected cases, since major lung resection can only be justified if it leads to a real oncological advantage. Repeated thoracotomies are possible, since there is no theoretical limit to reinterventions. Surgery of lung metastases has a therapeutic and curative role for some histology with acceptable rate of complications but it finds its role only in an aggressive multimodality approach. Indications can be discussed case by case and exceptions can be evaluated also in presence of different evidences. Children affected by metastatic tumors need to be managed by expert multidisciplinary oncological team in referral center with large experience.
RESUMO
BACKGROUND: Extensive clinical experience has demonstrated the potential usefulness of autologous fat tissue (AFT) graft in tissue reconstruction, repair or regeneration. In the present study, we evaluated the feasibility and safety of AFT in the repair of surgically injured lung surface. METHODS: Eighty consecutive procedures of pulmonary metastasectomy by laser precision resection, were performed in 66 patients between March 2010 and December 2012. In the first 20 procedures, AFT graft was applied on the wounded pulmonary surface without closure of parenchymal surface. The following 40 procedures were carried on without AFT (20 leaving the resection margins open and 20 closing the resection margins with a running suture). In the remaining 20 procedures, AFT was applied and the resection margins closed. The efficacy of this technique was evaluated by comparing the AFT group with the non-AFT group, with respect to prolonged alveolar air leakage (PAAL), time to drain removal, length of hospital stay, and patient survival at four years. RESULTS: The occurrence of PAAL was lower in the AFT group as compared to non-AFT group (17.5% versus 42.5%, p = 0.027), and median time to drain removal shorter (4 versus 6 days respectively, p = 0.016). Overall 4-year survival was 70% for AFT group, and 59% for non-AFT group (p = 0.34). CONCLUSIONS: This prospective cohort observational study demonstrated the feasibility and safety of AFT pulmonary grafting after laser metastasectomy. AFT graft improved pulmonary healing, by reducing the incidence and severity of PAAL. Moreover, there was no evidence of tumor promotion in the metastatic setting, with a similar overall survival at 4 years.

BACKGROUND AND PURPOSE: Adenoid cystic carcinoma (ACC) of salivary glands is characterized by long-term distant metastasis, most commonly in lungs. No agreement has been reached about the role of surgical treatment of pulmonary lesions. We evaluated the long-term results of lung metastasectomy for ACC in order to identify factors that should be taken into account in selecting patients eligible for surgery and treatment planning. PATIENTS AND METHODS: A retrospective study was conducted on 109 patients selected from our institutional experience and from the International Registry of Lung Metastases. Survival was calculated by Kaplan-Meier estimate and prognostic factors endowed with a predictive power for most other metastatic cancers were investigated. RESULTS: The cumulative survival was 66.8% at 5years and 40.5% at 10years. In patients with a disease-free interval (DFI) greater than 36months, the overall survival was 76.5% at 5years. Survival in case of complete surgical resection was 69.5% at 5years. Multivariate analysis confirmed DFI and completeness of resection resulted in the best prognostic variables. DISCUSSION: Lung metastasectomy should be considered as a therapeutic option to achieve local control of disease when 2 conditions are met: (1) complete surgical resection is feasible and (2) the time to pulmonary relapse after primary tumor treatment is greater than 36months. Symptomatic benefits of an incomplete lung resection in slow-growing tumors such as ACC remain uncertain. The turning point in the management of disseminated cancers will be clarified with biological profiling of ACC and the development of targeted therapies.

To improve the poor prognosis for children with metastatic osteosarcoma (OS), interleukin-2 (IL-2) was added to the standard treatment due to its capacity to activate lymphocytes and differentiate lymphocyte subsets into lymphokine-activated killer (LAK) cells that are capable of recognizing and killing various tumor cells. This study concerns a cohort of unselected patients aged < 18 years with metastatic OS, who were treated with IL-2, high-dose methotrexate, doxorubicin, cisplatin, ifosfamide, LAK reinfusion, and surgery, between 1995 and 2010. Thirty-five patients aged 4-17 years were involved. Thirty-two of the 35 patients underwent surgery on their primary tumor, and 25 had surgery on lung metastases too. Twenty-seven patients received IL-2 plus LAK reinfusion. The median follow-up was 130 months (77-228), and the 3-year event-free and overall survival rates were 34.3 and 45.0%, respectively. Eleven patients remained alive, all of whom achieved a complete surgical removal of the primary tumor and lung metastases (1 patient did not receive lung resections due to complete lung metastases remission). Patients who had a complete surgical remission of the primary and metastatic sites and who responded well to chemotherapy had a better event-free survival. These results confirm the importance of complete surgical remission and point to a noteworthy (though still be ameliorate) survival rate in our series of patients, underling a potential role for immunotherapy with IL-2 and LAK/NK cell activation.

Occasionally, breast cancer relapses in the subclavicular region. In patients with failed multimodal treatment, or in those who develop an isolated recurrence, surgical resection may be useful to remove all macroscopically evident diseases. However, the procedure may be technically demanding and there are no published data regarding its benefits. The aim of the present study was to evaluate the feasibility and safety of subclavicular resection in breast cancer and provide indications as to whether it can contribute to disease control. We used a transpectoral approach to surgically remove isolated breast cancer recurrence in the subclavicular region in seven consecutive patients presenting over 2 years; in the eighth case a transmanubrial approach was necessary. We found that the surgical approach proposed is feasible and safe, with a 75% rate of complete resection; however, the series was characterised by a high rate of local and distant relapse. We conclude that the technique may be useful, in selected cases, for palliation only.

Is sampling really effective in staging non-small cell lung cancer? The aim of the study was to assess if systematic nodal dissection is necessary in order to stage non-small cell lung cancer correctly or whether mediastinal lymph node sampling can be used and whether in selected cases it could replace systematic nodal dissection for the treatment of lung cancer. A prospective study was conducted in 94 patients affected by clinically resectable non-small cell lung cancer (stages I-IIIB) who were surgically treated by the same team of surgeons. During surgery mediastinal lymph node sampling was done first and then another surgeon completed the systematic nodal dissection and performed the lung resection. One hundred and ninety-three mediastinal nodal stations were investigated using the American Thoracic Society lymph node map to identify them. On analysing the 193 mediastinal nodal stations investigated, it emerged that in 181 cases (94%) mediastinal lymph node sampling and systematic nodal dissection yielded the same histopathological findings, whereas in 12 cases (6%) there was no agreement between the two techniques. The negative predictive value of mediastinal lymph node sampling was 92.8% (103/111). The results of the study show no statistical difference between mediastinal lymph node sampling and systematic nodal dissection in staging non-small cell lung cancer. However, it is possible that in a limited percentage of cases a nodal station could be understaged and thus the surgical resection could prove incomplete if mediastinal lymph node sampling alone is performed. Moreover, in those cases where mediastinal lymph node sampling detects N2 disease and systematic nodal dissection has not been completed, the intervention cannot be considered radical.
