Pathologic stage I non–small cell lung cancer with high levels of preoperative serum carcinoembryonic antigen: Clinicopathologic characteristics and prognosis

ObjectiveSurgery alone remains the standard therapy for patients with stage I non–small cell lung cancer. Although the preoperative serum level of carcinoembryonic antigen has been shown to be an independent prognostic factor, it has not yet been included in the staging system and does not alter the treatment strategy, especially in the selection of patients for adjuvant chemotherapy.MethodsFrom 1986 to 2003, preoperative and postoperative serum carcinoembryonic antigen levels were measured in 455 patients with completely resected pathologic stage I non–small cell lung cancer. We compared the clinicopathologic characteristics and outcomes among patients who had preoperative serum carcinoembryonic antigen levels within the normal range (N group, n = 323), patients who had high carcinoembryonic antigen levels before surgery but normal levels after surgery (HN group, n = 112), and patients who had high carcinoembryonic antigen levels before and after surgery (HH group, n = 20).ResultsThe significant characteristics of the HN group included the male sex, greater age, smoking, squamous cell histology, T2 status, lymphatic invasion, vascular invasion, and pleural invasion. Adenocarcinomas in patients of the HN group were more likely to be moderately to poorly differentiated. The 5-year survivals in the HN and HH groups were significantly lower (56.2% and 43.1%, respectively) than those in the N group (85.9%). Multivariate analysis revealed that greater age, non-adenocarcinoma histology, pleural invasion, and the carcinoembryonic antigen in the HN and HH groups were independent prognostic factors.ConclusionPatients with resected pathologic stage I non–small cell lung cancer and high preoperative serum carcinoembryonic antigen levels are a subgroup with a distinctly poor prognosis who display smoking-related clinicopathologic characteristics

Utility of a Computed Tomography-Based Navigation System (O-Arm) for Partial Vertebrectomy for Lung Cancer Adjacent to the Thoracic Spine: Technical Case Report

We describe successful vertebrectomy from a posterior approach using a computed tomography (CT)-based navigation system (O-arm) in a 53-year-old man with adenocarcinoma of the posterior apex of the right lung with invasion of the adjacent rib, thoracic wall, and T2 and T3 vertebral bodies. En bloc partial vertebrectomy for lung cancer adjacent to the thoracic spine was planned using O-arm. First, laminectomy was performed from right T2 to T3, and pedicles and transverse processes of T2 to T3 were resected. O-arm was used to confirm the location of the cutting edge in the T2 to 3 right vertebral internal body, and osteotomy to the anterior cortex was performed with a chisel. Next, the patient was placed in a left decubitus position. The surgical specimen was extracted en bloc. This case shows that O-arm can be used reliably and easily in vertebrectomy from a posterior approach and can facilitate en bloc resection

Combination Treatment of Perioperative Rehabilitation and Psychoeducation Undergoing Thoracic Surgery

Postoperative pulmonary complications are a risk associated with thoracic surgery. However, there have been few reports on cases at high risk of postoperative complications. Cancer patients often have negative automatic thoughts about illness, and these negative automatic thoughts are associated with reduced health behavior and physical activity. This case series demonstrates the successful combination treatment of perioperative rehabilitation and psychoeducation for negative automatic thoughts in two cancer patients who underwent thoracic surgery. One patient underwent pneumonectomy with laryngeal recurrent nerve paralysis; the other patient, who had a history of recurrent hepatic encephalopathy and dialysis, underwent S6 segmentectomy. Both patients had negative automatic thoughts about cancer-related stress and postoperative pain. The physical therapists conducted a perioperative rehabilitation program in which the patients were educated to replace their maladaptive thoughts with more adaptive thoughts. After rehabilitation, the patients had improved adaptive thoughts, increased physical activity, and favorable recovery without pulmonary complications. This indicates that the combination treatment of perioperative rehabilitation and psychoeducation was useful in two thoracic cancer surgery patients. The psychoeducational approach should be expanded to perioperative rehabilitation of patients with cancer

Model of lung cancer surgery risk derived from a Japanese nationwide web-based database of 78 594 patients during 2014–2015

OBJECTIVESUsing data obtained from a Japanese nationwide annual database with web-based data entry, we developed a risk model of mortality and morbidity after lung cancer surgery.METHODSThe characteristics and operative and postoperative data from 80 095 patients who underwent lung cancer surgery were entered into the annual National Clinical Database of Japan data sets for 2014 and 2015. After excluding 1501 patients, the development data set for risk models included 38 277 patients entering in 2014 and the validation data set included 40 317 patients entering in 2015. Receiver–operating characteristic curves were generated for the outcomes of mortality and composite mortality/major morbidity. The concordance index was used to assess the discriminatory ability and validity of the model.RESULTSThe 30-day mortality and overall mortality rates, including in-hospital deaths, were 0.4% and 0.8%, respectively, in 2014, and 0.4% and 0.8%, respectively, in 2015. The rate of major morbidity was 5.6% in 2014 and 5.6% in 2015. Several risk factors were significantly associated with mortality, namely, male sex, performance status, comorbidities of interstitial pneumonia and liver cirrhosis, haemodialysis and the surgical procedure pneumonectomy. The concordance index for mortality and composite mortality/major morbidity was 0.854 (P < 0.001) and 0.718 (P < 0.001), respectively, for the development data set and 0.849 (P < 0.001) and 0.723 (P < 0.001), respectively, for the validation data set.CONCLUSIONSThis model was satisfactory for predicting surgical outcomes after pulmonary resection for lung cancer in Japan and will aid preoperative assessment and improve clinical outcomes for lung cancer surgery

Annual report by The Japanese Association for Thoracic Surgery

All data regarding cardiovascular surgery and thoracic surgery were obtained from NCD, whereas data regarding esophageal surgery were collected from survey questionnaire by The Japanese Association for Thoracic Surgery forms because NCD of esophageal surgery does not include non-surgical cases (i.e., patients with adjuvant chemotherapy or radiation alone). Based on the change in data aggregation, there are several differences between this 2015 annual report and previous annual reports: the number of institutions decreased in each category from 578 (2014) to 568 (2015) in cardiovascular, from 762 to 714 in general thoracic and from 626 to 571 in esophageal surgery. Because more than two departments in the same institute registered their data to NCD individually, we cannot calculate correct number of institutes in this survey. Then, the response rate is not indicated in the category of cardiovascular surgery (Table 1), and the number of institutions classified by the operation number is also not calculated in the category of cardiovascular surgery (Table 2)
