Relapse in resected lung cancer revisited: does intensified follow up really matter? A prospective study

Backgroundbeside the well known predominance of distant vs. loco-regional relapse, several aspects of the relapse pattern still have not been fully elucidated.Methodsprospective, controlled study on 88 patients operated for non-small cell lung cancer (NSCLC) in a 15 months period. Stage IIIA existed in 35(39.8%) patients, whilst stages IB, IIA and IIB existed in 10.2%, 4.5% and 45.5% patients respectively. Inclusion criteria: stage I-IIIA, complete resection, systematic lymphadenectomy with at least 6 lymph node groups examined, no neoadjuvant therapy, exact data of all aspects of relapse, exact data about the outcome of the treatment.Resultspostoperative lung cancer relapse occurred in 50(56.8%) patients. Locoregional, distant and both types of relapse occurred in 26%, 70% and 4% patients respectively. Postoperative cancer relapse occurred in 27/35(77.1%) pts. in the stage IIIA and in 21/40(52.55) pts in the stage IIB. In none of four pts. in the stage IIA cancer relapse occurred, unlike 22.22% pts. with relapse in the stage IB. The mean disease free interval in the analysed group was 34.38 ± 3.26 months.The mean local relapse free and distant relapse free intervals were 55 ± 3.32 and 41.62 ± 3.47 months respectively Among 30 pts. with the relapse onset inside the first 12 month after the lung resection, in 20(66.6%) pts. either T3 tumours or N2 lesions existed. In patients with N0, N1 and N2 lesions, cancer relapse occurred in 30%, 55.6% and 70.8% patients respectivelyRadiographic aspect T stage, N stage and extent of resection were found as significant in terms of survival. Related to the relapse occurrence, although radiographic aspect and extent of resection followed the same trend as in the survival analysis, only T stage and N stage were found as significant in the same sense as for survival. On multivariate, only T and N stage were found as significant in terms of survival.Specific oncological treatment of relapse was possible in 27/50(54%) patients.Conclusionthe intensified follow up did not increase either the proportion of patients detected with asymptomatic relapse or the number of patients with specific oncological treatment of relapse.

Solitary fibrous pleural tumor associated with loss of consciousness due to hypoglycemia

The patient suffered loss of consciousness, dysarthria and right sided hemiparesis. The CT scan and MRI scans were negative. These findings are more in keeping with a diagnosis of Transient Ischemic Attack (TIA) or mild CVA. Hypoglycemia per se does not usually cause hemiparesis. The blood glucose level was low but I am not sure if one can conclude that hypoglycemia caused the above noted neurological signs and symptoms. The authors do not present any data to prove that this patient had “hypoglycemic coma”.

Postoperative complications do not influence the pattern of early lung function recovery after lung resection for lung cancer in patients at risk

BackgroundThe pattern and factors influencing the lung function recovery in the first postoperative days are still not fully elucidated, especially in patients at increased risk.MethodsProspective study on 60 patients at increased risk, who underwent a lung resection for primary lung cancer. Inclusion criteria: complete resection and one or more known risk factors in form of COPD, cardiovascular disorders, advanced age or other comorbidities. Previous myocardial infarction, myocardial revascularization or stenting, cardiac rhythm disorders, arterial hypertension and myocardiopathy determined the increased cardiac risk. The severity of COPD was graded according to GOLD criteria. The trend of the postoperative lung function recovery was assessed by performing spirometry with a portable spirometer.ResultsCardiac comorbidity existed in 55%, mild and moderate COPD in 20% and 35% of patients respectively. Measured values of FVC% and FEV1% on postoperative days one, three and seven, showed continuous improvement, with significant difference between the days of measurement, especially between days three and seven. There was no difference in the trend of the lung function recovery between patients with and without postoperative complications. Whilst pO2 was decreasing during the first three days in a roughly parallel fashion in patients with respiratory, surgical complications and in patients without complications, a slight hypercapnia registered on the first postoperative day was gradually abolished in all groups except in patients with cardiac complications.ConclusionExtent of the lung resection and postoperative complications do not significantly influence the trend of the lung function recovery after lung resection for lung cancer.

Influence of Pulmonary Rehabilitation on Lung Function Changes After the Lung Resection for Primary Lung Cancer in Patients with Chronic Obstructive Pulmonary Disease

Influence of physiotherapy on the outcome of the lung resection is still controversial. Study aim was to assess the influence of physiotherapy program on postoperative lung function and effort tolerance in lung cancer patients with chronic obstructive pulmonary disease (COPD) that are undergoing lobectomy or pneumonectomy. The prospective study included 56 COPD patients who underwent lung resection for primary non small-cell lung cancer after previous physiotherapy (Group A) and 47 COPD patients (Group B) without physiotherapy before lung cancer surgery. In Group A, lung function and effort tolerance on admission were compared with the same parameters after preoperative physiotherapy. Both groups were compared in relation to lung function, effort tolerance and symptoms change after resection. In patients with tumors requiring a lobectomy, after preoperative physiotherapy, a highly significant increase in FEV1, VC, FEF50 and FEF25 of 20%, 17%, 18% and 16% respectively was registered with respect to baseline values. After physiotherapy, a significant improvement in 6-minute walking distance was achieved. After lung resection, the significant loss of FEV1 and VC occurred, together with significant worsening of the small airways function, effort tolerance and symptomatic status. After the surgery, a clear tendency existed towards smaller FEV1 loss in patients with moderate to severe, when compared to patients with mild baseline lung function impairment. A better FEV1 improvement was associated with more significant loss in FEV1. Physiotherapy represents an important part of preoperative and postoperative treatment in COPD patients undergoing a lung resection for primary lung cancer.

Comparison of mediastinal lymph node status and relapse pattern in clinical stage IIIA non‐small cell lung cancer patients treated with neoadjuvant chemotherapy versus upfront surgery: A single center experience

In spite of the progress made in neoadjuvant therapy for operable non small‐cell lung cancer (NSCLC), many issues remain unsolved, especially in locally advanced stage IIIA.

Rare tracheal tumor: Solitary plasmacytoma

Primary tracheal tumors are rare and trachea is an exceedingly rare site of extramedullary plasmacytoma (EMP). We report a case of solitary tracheal plasmacytoma causing symptoms of airway obstruction in a 59-year-old man. Flow/volume loop indicated the fixed central airway obstruction. Computerized tomography and bronchoscopy demonstrated a sessile tumor on posterior tracheal wall obstructing 80% of the lumen. Partial tracheal resection with T-T anastomosis was performed. Pathologic analysis of resected mass revealed EMP. Additional investigations excluded multiple myeloma. There are no signs of disease recurrence after 7-year follow-up.

Early postoperative changes in lung function after resection for lung cancer - do the complications have influence?

Method Sixty patients undergoing surgical resection (sublobar, lobectomy, and pneumonectomy) for non-small cell lung cancer were included in a prospective, single institution study. Sex, age, stage and type of lung cancer, comorbidities, preoperative values of lung function tests including DLCO and exercise test were analyzed. Postoperative complications were classified as surgical, respiratory and cardiovascular. FEV1 and FVC were measured on postoperative days 1, 3 and 7, regardless of postoperative complications. Results Study encompassed 60 patients (70% male, mean age 60.9 ± 8.4 and 30% female, mean age 56.9 ± 6.5). Mild degree of COPD was noted in 20% and moderate in 35% of patients, according to GOLD classification. All postoperative adverse events, not only major complications were recorded. Respiratory complications occurred in 20%, surgical in 41.7% and cardiac in 19% of patients. Measured postoperative values of FVC% and FEV1% on days 1, 3 and 7 after surgery shoved continuous improvement, with significant difference between the days of measurement, specially days 3 and 7. Values recorded on day 7 did not differ from ppo FEV1%. No difference in early postoperative trend of lung function recovery was noted between patients without and with postoperative complications. However, patients that developed respiratory complications showed significantly lower values of FEV1 and FVC on postoperative day 1. Conclusions Early lung function after resection for lung cancer shows significant improvement despite of postoperative complications.
