Superior vena cava resection for lung and mediastinal malignancies: a single-center experience with 70 cases.

BACKGROUND: The oncologic value of superior vena cava (SVC) resection for lung and mediastinal malignancies remains controversial. In this context, we have reviewed our experience in the treatment of locally advanced lung and mediastinal tumor invading the SVC system, analyzing postoperative outcome and long-term oncologic results. METHODS: The clinical data of patients who underwent SVC resection were retrospectively analyzed to assess postoperative mortality, and overall and procedure-specific morbidity. Overall survival was calculated for mediastinal and lung tumor groups. RESULTS: From 1998 to 2004, 70 consecutive patients (52 with lung cancer and 18 with mediastinal tumors) underwent SVC system resection. There were 25 replacements (36%) of the SVC system by prosthesis, whereas the remaining underwent partial resection. Major postoperative morbidity and mortality rates in lung cancer patients were 23% and 7.7%, respectively (50% and 5.6% in mediastinal tumors). In the lung cancer group, 5-year survival probability was 31%, and it was affected by mediastinal nodal status (5-year survival in N0-N1 patients 52%, 21% in N2 patients, 0 in N3 patients). Median survival for mediastinal tumors was 49 months. CONCLUSIONS: In conclusion, SVC resection may achieve permanent cure in patients who would have been defined as inoperable 10 years ago. In the case of mediastinal tumors, the need for SVC resection alone should not be considered a contraindication for surgery when prosthetic replacement is feasible. In the case of lung tumors, infiltration of SVC can achieve satisfactory long-term results after neoadjuvant chemotherapy, only when pathologic N2 disease is excluded by preoperative mediastinoscopy.

Pulmonary artery reconstruction by a custom-made heterologous pericardial conduit in the treatment of lung cancer.

Lung cancer may involve the pulmonary artery (PA) either by direct extension of the primary tumor or by invasion of the hilar lymph nodes. In these instances, a radical resection is usually a pneumonectomy despite distal functioning lung tissue. To spare the lung parenchyma, angioplastic procedures requiring removal of a portion of the arterial wall or a circumferential resection with arterial reconstruction have been used. Several techniques of pulmonary arterioplasty have been explored suggesting that the incidence of postoperative complications is acceptably low and long-term local control can be achieved. Over a period of 7 years, 84 angioplastic procedures (alone or associated with bronchoplasty) were performed at our institution. Partial PA resection was performed in 80 (95.2%) patients. Reconstruction was performed by running suture in 63 (75%) patients and using a pericardial patch in 17 (20.2%) cases (16 autologous and 1 heterologous). A complete PA resection and reconstruction was performed in four (4.8%) patients by a polytetrafluoroethylene (PTFE) prosthesis (n=2) and by a custom-made bovine pericardial conduit (n=2). The latter are the topic of this report.

Subclavicular recurrence of breast cancer: does surgery play a role?

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.

Sequential chemotherapy with cisplatin/gemcitabine (CG) followed by mitoxantrone/methotrexate/mitomycin (MMM) in patients with malignant pleural mesothelioma. A multicenter Italian Phase II Study (SITMP1).

PURPOSE: We performed a multicenter phase II trial to evaluate the impact on the activity, efficacy, symptom control and safety of using two active regimens in a sequential schedule (cisplatin/gemcitabine followed by mitoxantrone/methotrexate/mitomycin) as first-line chemotherapy for unresectable malignant pleural mesothelioma (MPM). PATIENTS AND METHODS: A total of 54 patients received cisplatin 75 mg/m(2) on day 1 and gemcitabine 1,200 mg/m(2) on days 1 and 8, every 3 weeks for four courses (CG regimen) followed by mitoxantrone 10 mg/m(2) on day 1, methotrexate 35 mg/m(2) on day 1 and mitomycin 7 mg/m(2) on day 1, every 3 weeks with mitomycin in alternate cycles for four courses (MMM regimen). RESULTS: We observed 3 complete responses (CRs) (5.6%) and 13 partial responses (PRs) (24.0%), with an overall response rate (ORR) of 29.6% (95% confidence interval, 17-42%), 33 stable disease (SD) (61.1%) and 5 progressive disease (PD) (9.2%). Median time to progression (TTP) was 9.5 months (range, 2-23). Median overall survival (OS) was 13 months (range, 3-33); 1-year survival rate was 63%. The treatment produced a good symptom control, with an improvement during chemotherapy in dyspnea and pain in 52.9 and 48.3% of patients, respectively. The major toxicity observed was hematological. Grades 3-4 NCI-CTC v 2.0 toxicity with the CG regimen included: neutropenia (11.1%), anemia (1.9%), thrombocytopenia (7.4%), vomiting (11.1%) and with the MMM regimen: neutropenia (35.2%), anemia (5.5%), thrombocytopenia (7.4%) and stomatitis (1.9%). CONCLUSION: This phase II study with the sequential approach of two active regimens showed a good disease control in MPM, with symptom improvement and only mild toxicity.

Multimodality treatment of unresectable stage III non-small cell lung cancer: interim analysis of a phase II trial with preoperative gemcitabine and concurrent radiotherapy.

OBJECTIVE: We report the preliminary results of a phase II trial undertaken to determine the feasibility and efficacy of gemcitabine and concurrent radiotherapy in patients with inoperable stage III non-small cell lung cancer. METHODS: Between February 2001 and June 2003, a total of 46 patients (37 male and 9 female, median age 64 years) with clinical stage III non-small cell lung cancer (41 cIIIA and 5 cIIIB) were enrolled in a combined chemoradiation protocol with gemcitabine as the chemotherapeutic agent. Gemcitabine (350 mg/m2) was administered weekly for 5 consecutive weeks as a 30-minute intravenous infusion before radiotherapy (total dose 50.4 Gy, 1.8 Gy/d). Toxicity was routinely assessed. Those patients with disease judged to be resectable at restaging underwent surgery. RESULTS: Toxicity was moderate, with the exception of 1 grade 3 thrombocytopenia. All but 5 patients were available for restaging. No complete responses were observed. Thirty-four patients (82.9%) had partial responses, 5 (12.2%) had stable disease, and 2 (4.9%) had progressive disease. Twenty-nine of 46 patients (63%, 27 cIIIA and 2 cIIIB) underwent surgery. Radical resection was possible in all cases. Surgery included 17 lobectomies, 4 bilobectomies, and 8 pneumonectomies. There were no deaths. Morbidity was 13.8% (4/29). Pathologic downstaging to stage 0 or I was observed in 18 patients (39%, 18/46). After a median follow-up of 13 months (range 2-28 months), 24 of the patients who had undergone operation (86.2%) were alive, with a median disease-free survival of 16 months. Overall 2-year survival was 66.1%, with a significant difference between resected and unresected disease (82% vs 36%, P = .0002). CONCLUSION: The results of this induction trial confirm the feasibility and the efficacy of gemcitabine with concurrent radiotherapy.

Anomalous right upper lobe venous drainage.

Anomalous pulmonary venous return is a rare congenital anomaly mainly involving the right lung and is often associated with congenital intracardiac malformations as atrial septal defect. We report a case of anomalous right upper lobe venous drainage resulting in two right upper lobe veins draining into the azygous vein and into the confluence between superior vena cava and azygous vein, respectively. Preoperative identification of such an aberrant venous drainage is useful for avoiding unexpected intraoperative bleeding.

Does chemotherapy increase the risk of respiratory complications after pneumonectomy?

OBJECTIVE: The impact of induction chemotherapy on postoperative complications after pneumonectomy remains unclear. The aim of the study was to test the hypothesis that chemotherapy may increase the risk of postoperative respiratory complications. METHODS: Data from 202 consecutive standard pneumonectomies performed for lung cancer were collected and analyzed. Postoperative and 90-day mortality, overall morbidity, and respiratory complication rates were evaluated in patients who had no induction treatment (group A, n = 103) as well as in those who received it (n = 99, group B). Preoperative chemotherapy was inserted as a variable together with 12 other variables (age, sex, smoking status, body mass index, previous cardiac event, American Society of Anesthesiologists score, preoperative forced expiratory volume in 1 second [percent], diffusion capacity for carbon monoxide adjusted for alveolar volume [percent], side of pneumonectomy, perfusion of the removed lung, operating time, and blood transfusion) into univariate and multivariate logistic regression. RESULTS: No difference in terms of mortality was recorded between group A (4.9%) and group B (3%, P > .05). Respiratory complications were more frequent in group B than in group A (19 cases, 19.2%, vs 7 cases, 6.8%, P = .008). Univariate logistic regression has demonstrated that pulmonary complications were more frequent in patients over the age of 70 than in those aged 70 or less (25.7% vs 10.2, P = .02), in those with a lower diffusion capacity adjusted for alveolar volume (18.3% vs 5.95%, P = .06), and in patients who received preoperative chemotherapy (19.2% vs 6.8, P = .008). Logistic regression confirmed the role of age (odds ratio = 6.3), preoperative chemotherapy (odds ratio = 4.4), and diffusion capacity adjusted for alveolar volume (odds ratio = 0.33) as risk factors of respiratory complications. CONCLUSIONS: Standard pneumonectomy is a safe procedure even after induction chemotherapy, with a mortality rate in the order of 5%, but this increases in patients over the age of 70 years. In the case of induction chemotherapy, the risk of respiratory complications is significantly increased, apparently not affecting the overall mortality rate.

A primary pure yolk sac tumor of the lung exhibiting CDX-2 immunoreactivity and increased serum levels of alkaline phosphatase intestinal isoenzyme.

Malignant extragonadal germ cell tumors primary to the lung are quite uncommon lesions, but pure yolk sac tumor is even more exceptional. This is believed to be the first reported case of yolk sac tumor of the lung in which an intense and diffuse immunoreactivity for CDX2, a marker of intestinal differentiation reportedly expressed also in gonadal yolk sac tumor, was associated with increased serum levels of the alkaline phosphatase intestinal isoform. Nine months after radical surgery and adjuvant chemotherapy, the patient is alive and well without evidence of recurrent or metastatic disease and with serum levels of the alkaline phosphatase intestinal isoform within normal limits. The pathologist should be aware of yolk sac tumor arising in the lung and that alkaline phosphatase intestinal isoform could become an additional serum marker for such a tumor.

Pretreatment quality of life and functional status assessment significantly predict survival of elderly patients with advanced non-small-cell lung cancer receiving chemotherapy: a prognostic analysis of the multicenter Italian lung cancer in the elderly study.

PURPOSE: To study the prognostic value for overall survival of baseline assessment of functional status, comorbidity, and quality of life (QoL) in elderly patients with advanced non-small-cell lung cancer treated with chemotherapy. PATIENTS AND METHODS: Data from 566 patients enrolled onto the phase III randomized Multicenter Italian Lung Cancer in the Elderly Study (MILES) study were analyzed. Functional status was measured as activities of daily living (ADL) and instrumental ADL (IADL). The presence of comorbidity was assessed with a checklist of 33 items; items 29 and 30 of the European Organisation for Research and Treatment of Cancer (EORTC) core questionnaire QLQ-C30 (EORTC QLQ-C30) were used to estimate QoL. ADL was dichotomized as none versus one or more dependency. For IADL and QoL, three categories were defined using first and third quartiles as cut points. Comorbidity was summarized using the Charlson scale. Analysis was performed by Cox model, and stratified by treatment arm. RESULTS: Better values of baseline QoL (P = .0003) and IADL (P = .04) were significantly associated with better prognosis, whereas ADL (P = .44) and Charlson score (P = .66) had no prognostic value. Performance status 2 (P = .006) and a higher number of metastatic sites (P = .02) also predicted shorter overall survival. CONCLUSIONS: Pretreatment global QoL and IADL scores, but not ADL and comorbidity, have significant prognostic value for survival of elderly patients with advanced non-small-cell lung cancer who were treated with chemotherapy. Using these scores in clinical practice might improve prognostic prediction for treatment planning.

Farnesyltransferase inhibitors and human malignant pleural mesothelioma: a first-step comparative translational study.

It is known that the potential clinical use of farnesyltransferase inhibitors (FTI) could be expanded to include cancers harboring activated receptor tyrosine kinases. Approximately 70% of malignant pleural mesotheliomas (MPM) overexpress epidermal growth factor receptors (EGFR) and a subset express both EGFR and transforming growth factor alpha (TGF-alpha), suggesting an autocrine role for EGFR in MPM. We checked on MPM cells (10 human cell lines, 11 primary cultures obtained by human biopsies, and 7 short-term normal mesothelial cell cultures) concerning the following: (a) the relative overexpression of EGFR (Western blotting, flow cytometry, immunohistochemistry), (b) the relative expression of EGFR ligands (EGF, amphiregulin, TGF-alpha, ELISA), (c) the relative increase of the activated form of Ras (Ras-bound GTP) after EGF stimulation (Ras activation assay), (d) the efficacy of five different FTIs (HDJ2 prenylation, cell cytotoxicity, and apoptosis using ApopTag and gel ladder). EGFR was overexpressed in MPM cells compared with normal pleural mesothelial cells in equivalent levels as in non-small cell lung cancer cells A459. MPM cells constitutively expressed EGFR ligands; however, Ras activation was attenuated at high EGF concentrations (100 ng/mL). Growth of MPM cells was substantially not affected by treatment with different FTIs (SCH66336, BMS-214662, R115777, RPR-115135, and Manumycin). Among these, BMS-214662 was the only one moderately active. BMS-214662 triggered apoptosis in a small fraction of cells (not higher than 30%) that was paralleled by a slight decrease in the levels of TGF-alpha secreted by treated MPM cells. Our data highlighted the concept that the same signaling pathway can be regulated in different ways and these regulations can differ between different cells of different origin.
