Pulmonary Metastases from NSCLC and MPLC (Multiple Primary Lung Cancers): Management and Outcome in a Single Centre Experience.

BACKGROUND: This is an institutional review of surgical management of second pulmonary tumours in patients with history of Non-small Cell Lung Cancer (NSCLC) resection according to The American College of Chest Physicians' (ACCP) revision to the Martini and Melamed's criteria for the classification of multiple primary lung cancers (MPLC). METHODS: All patients who underwent iterative pulmonary resections for pulmonary metastasis (Group A) or MPLC (Group B) between 2006 and 2012 were reviewed and their survivals compared accordingly. The main criteria of insertion in Group B were different histology and the same histology with disease-free interval ≤ 4 years; we excluded loco-regional recurrence in nodes and/or on bronchial stump. RESULTS: Group A: Twenty patients; Disease free time (DFT) after first operation was 15.2 months (range 2-44). One, two and three years overall survival after second resection was 74%, 29%, 14% respectively. Group B: Thirty-six patients. One, two and three years overall survival was 94%, 81%, and 69% respectively. No statistical differences on outcome were found between the two groups in spite of the apparent worse survival rate for Group A (p=.197). CONCLUSIONS: A further resection for additional nodules, whether designated as intrapulmonary metastases or second primary NSCLC, can be an appropriate curative strategy in selected patients with unimpaired respiratory function and no evidence of distant metastatic disease. The site, the extent of the second resection, the histology and even the stage are unlikely to be related to survival.

Tracheo-bronchoplastic procedures for NSCLC: single-centre experience.

BACKGROUND: The purpose of this study was to assess operative mortality, morbidity, and long-term results of the totality of sleeve resections performed at our institutions over the last eight years, including sleeve lobectomies (SL), carinoplasties with total lung sparing (CP) and sleeve pneumonectomies (SP). METHODS: A retrospective review of all the patients who underwent a tracheo-bronchial resection for bronchial cancer between 2004 and 2012 was undertaken. Bronchial sleeve resections and combined bronchial and vascular sleeve resections were described. RESULTS: The resulting group studied was 22 patients. SL and SP had a perioperative mortality rate of 7.1% and 28.5% respectively; morbidity rates were 21.4% for SL and 42.8% for SP. Global one-year and three-year survival was 75% and 63% respectively. One-year survival was 84% for SL and 53% for SP; three-year survival rate was 65% and 35% respectively (p=0.24). The absence of nodal metastatic involvement was associated with a better outcome with a three-year survival rate of 69% in the N0 group vs a 36% rate in the N+ group. CONCLUSIONS: Sleeve resection procedures achieved satisfactory local control of the tumour in our experience even in patients with preoperative contraindication to pneumonectomy, with acceptable mortality and morbidity rates.

Desmoid tumour of the thoracic outlet in a 70 year-old man successfully removed through cervico-thoracic Dartevelle approach.

Desmoid tumours have a strong tendency for local invasion and recurrence. A 70 year-old male presented with cervical and left shoulder pain associated with a supraclavicular mass. The computed-tomography showed an expansive lesion measuring 10 cm × 6 cm × 5.5 cm in the left supraclavicular space. At magnetic resonance imaging the subclavian vessels and the brachial plexus were dislocated anteriorly but not infiltrated. An incisional biopsy suggested a desmoid tumour. An anterior cervicothoracic approach was used to remove the tumour. The chest wall was reconstructed with titanium bars and a polytetrafluoroethylene-patch. The clavicle was fixed using a titanium clip. The post-operative course was uneventful. The patient was treated with adjuvant radiation therapy. After six months the patient is in good clinical condition free from disease recurrence. In conclusion, desmoid tumour of the thoracic outlet is a challenging situation. Wide radical resection should be attempted whenever possible. The Dartevelle approach gives an optimal surgical field with direct control of vessels and nerve roots facilitating tumour dissection and radical resection en-bloc with the chest wall. The chest wall reconstruction with titanium bars and clips is a simple and effective method to guarantee good respiratory function and to stabilise the shoulder girdle.

Sternal resection and reconstruction for local recurrence of breast cancer using the sternal allograft transplantation technique.

Sternal involvement in patients with breast cancer is relatively rare and its treatment is still controversial. Surgery is usually indicated in cases of single metastases in a multimodality protocol. Partial or complete sternectomy associated or not with the resection of surrounding tissues is the technique of choice to obtain safety margins and radical treatment of the disease. The most challenging part of the operation is the reconstruction of the anterior chest wall in order to avoid secondary complications and respiratory failure. In the last few years, different techniques and materials have been used to reconstruct the sternum. We report our experience in two patients with recurrent breast cancer using the sternal allograft technique to replace the sternum after partial sternectomy. The use of a sternal-allograft provides excellent functional and cosmetic results without complications during the follow-up period. The implantation technique is simple and reproducible.

Can topical application of tranexamic acid reduce blood loss in thoracic surgery? A prospective randomised double blind investigation.

OBJECTIVE: The systemic or topical use of antifibrinolytic agents is effective in reducing postoperative bleeding and blood product transfusion in cardiac surgery. We sought to study the effect of the topical application of tranexamic acid into the pleural space to reduce postoperative bleeding after lung surgery. METHODS: This was a prospective randomised double blind placebo controlled investigation. From May-2010 to February-2012, 89-patients, scheduled for pulmonary resection, were randomly allocated to one of the two study groups. Group-A received 5 g of tranexamic-acid in 100 ml of saline solution. Group-B received 100 ml of saline solution as placebo. RESULTS: The blood loss in the first 12-h was significantly less in group-A. The same trend was observed in the first 24-h but without reaching a true statistical significance. The mean volume of blood transfusion was statistically lower in group-A. The analysis between post-operative haemoglobin concentration, haematocrit, platelet-count, international-normalised-ratio, fibrinogen and partial-thromboplastin-time of both groups was not statistically significant. CONCLUSION: In our experience, the topical use of tranexamic-acid after lung surgery reduces postoperative bleeding and blood transfusion volume. The topical administration of tranexamic-acid is safe without increasing the risk of post-operative complications related to pharmacological side-effects.

Accuracy of transthoracic ultrasound for the detection of pleural adhesions.

OBJECTIVES: In the era of minimally invasive surgery, preoperative detection of pleural adhesions can be very useful for the assessment of surgical approach, because pleural adhesions are the main contraindication to video-assisted thoracoscopy. The aim of this study was to assess the sensitivity and specificity of transthoracic ultrasound in the detection of pleural adhesions prior to thoracic surgery. METHODS: From February 2010 to January 2011, 142 consecutive patients (male, 98; female, 44; age range, 36-83 years, mean age, 63.4 years) undergoing surgical thoracic intervention (except for pneumothorax) were preoperatively scanned by two different surgeons. According to thoracic wall projections of lung segments, we created a nine-region topographic map, in which every pulmonary area was scanned to assess the presence or the absence of 'gliding sign' (lesion-by-lesion analysis). During operations the surgeon, blinded to the prediction, confirmed or excluded each suspected adhesion or documented other adhesions not previously identified. RESULTS: A total of 1192 predictions were made. Ultrasound predictions were confirmed 1124 times and refuted 68 times. Sensitivity was 80.6% (95% confidence interval, 0.740-0.872) and specificity 96.1% (95% confidence interval, 0.949-0.973). The positive predictive value was 73.2% and the negative predictive value was 97.4%. CONCLUSIONS: Transthoracic ultrasound is an effective method for predicting pleural adhesions before thoracic surgery in experienced hands. Its safety, feasibility and low cost make it a useful method for the planning of minimally invasive surgical interventions.

Surgical results and long-term follow-up of T(4)-non-small cell lung cancer invading the left atrium or the intrapericardial base of the pulmonary veins.

Patients with locally advanced non-small cell lung cancer infiltrating the left atrium (LA) or the intrapericardial base of the pulmonary veins (PVs) are generally not considered good candidates for surgery because of the poor long-term survival. In the last 10 years, 31 consecutive patients with non-small cell lung cancer directly invading the LA or the intrapericardial base of the PVs underwent surgery. Pneumonectomy was the operation performed most frequently. In-hospital mortality was 9.7% and overall morbidity was 52%. One-, 2- and 3-year survival rates were 64, 46 and 30%, respectively with a mean survival of 22 months. The systemic recurrence of disease was the major cause of death at follow-up. At statistical analyses, the N-factor and the type of operation were related to poor long-term survival. In these patients, surgery could be performed with an acceptable operative mortality and morbidity. Surgery should be considered whenever a complete resection is technically possible. A careful preoperative evaluation is mandatory to select good candidates for surgery.

Unusual delayed presentation of post-traumatic intrapericardial hernia associated with intestinal occlusion.

AIM: We report a case of a 64-year-old man, admitted to our department following the onset a few months earlier of canalization disorders and a sensation of retrosternal tension. MATERIAL OF STUDY: Patient's history revealed blunt thoraco-abdominal trauma with multiple costal fractures 15 years earlier as a result of a road accident and a cholecystectomy at the age of 57. A barium meal revealed an intrapericardial displacement of some intestinal loops; as the patient suffered acute intestinal occlusion with severe abdominal pain associated with nausea and vomiting, we performed an emergency median xipho-umbilical laparotomy, making it possible to identify both the site of the retrosternal diaphragmatic laceration with intrapericardial colonic herniation and the true cause of the occlusion: an adhesion, caused by the previous cholecistectomy, which was strangulating a jejunal loop. After detaching the adhesion between the colon and the pericardium, the viscera were replaced in the abdominal cavity and the diaphragmatic opening was closed. RESULTS: The post-operative period was uneventful; a barium enema demonstrated the abdominal dislocation of the viscera. No recurrence was detected during the 48 months of follow-up. CONCLUSIONS: A rare pathological event, such as an intrapericardial diaphragmatic hernia, was combined with intestinal occlusion, initially attributed to a further complication of the hernia itself but in actual fact independent of the hernia and a consequence of a previous cholecystectomy.
