OBJECTIVETo evaluate and compare the value of stair climbing tests and conventional pulmonary function tests in the prediction of postoperative cardiopulmonary complications in non-small cell lung cancer patients underwent surgery.
METHODSFrom April 1, 2010 to Jan. 30, 2012, a total of 162 patients with thoracic carcinoma underwent stair climbing test (SCT) and conventional pulmonary function tests (PFT) preoperatively. The correlation of postoperative cardiopulmonary complications with the SCT and PFT parameters were analyzed retrospectively using chi-square test, independent sample t test and binary logistic regression analysis.
RESULTSOf the 162 patients, 19 without operation were excluded, due to an advanced stage (9 cases), poor cardiopulmonary function (5 cases), rejecting operation (4 cases) and exploration alone (1 case). 143 cases were eligible and evaluated eventually. Forty-one of the 143 patients (28.7%) had postoperative cardiopulmonary complications, but no death occurred. The patients were stratified into groups based on the time of stair climbing 5 stories (18.36 m, t, <92 s, ≥ 92 s). Exercise oxygen desaturation (EOD) during the stair climbing test (<5%, ≥ 5%) and the difference between the pulse at resting state and the pulse at end of stair climbing test (ΔP, <55 beats/min, ≥ 55 beats/min), respectively. The rate of postoperative cardiopulmonary complications was significantly higher in the group with t ≥ 92 s, EOD ≥ 5% and ΔP < 55 beats/min (38.5%, 42.0% and 35.1%, respectively) than that in the group with t<92 s, EOD<5% and ΔP ≥ 55 beats/min (16.9%, 21.5% and 18.2%, respectively). Binary logistic regression analysis showed that postoperative cardiopulmonary complications were independently correlated with EOD and lung function which did not meet the requirement of the lung resection operation mode.
CONCLUSIONSA symptom-limited stair climbing test is a safe, simple and low-cost method to evaluate the cardiopulmonary function preoperatively. It can predict the occurrence of postoperative cardiopulmonary complications in non-small cell lung cancer patients. Conventional pulmonary function tests and stair-climbing test can be recommended to be routinely performed in all patients with non-small cell lung cancer before thoracic surgery.

BACKGROUND:
Chronic obstructive pulmonary diseases (COPD) affects 45%-63% of lung cancer patients worldwide. Lung cancer patients complicated with COPD have decreased cardiopulmonary function and increased perioperative risk, and their postoperative exercise endurance and lung function are significantly lower than those with conventional lung cancer. Previous studies have shown that postoperative exercise training can improve the exercise endurance of unselected lung cancer patients, but it is unclear whether lung cancer patients with COPD can also benefit from postoperative exercise training. This study intends to explore the effects of postoperative exercise training on exercise endurance, daily activity and lung function of lung cancer patients with COPD.
METHODS:
Seventy-four patients with non-small cell lung cancer (NSCLC) complicated with COPD who underwent pneumonectomy in the lung cancer center of West China Hospital of Sichuan University from August 5, 2020 to August 25, 2021 were prospectively analyzed. They were randomly divided into exercise group and control group; The patients in the two groups received routine postoperative rehabilitation in the first week after operation, and the control group was given routine nursing from the second week. On this basis, the exercise group received postoperative exercise rehabilitation training for two weeks. Baseline evaluation was performed 3 days before operation and endpoint evaluation was performed 3 weeks after operation.
RESULTS:
The exercise endurance, daily activity and pulmonary function test results of the two groups decreased from baseline to the end point. However, after the operation and intervention program, the maximum oxygen consumption of Cardiopulmonary Exercise Test and the walking distance of 6-Minute Walking Test in the exercise group were significantly better than those in the control group [(13.09±1.46) mL/kg/min vs (11.89±1.38) mL/kg/min, P=0.033; (297±46) m vs (243±43) m, P=0.041]. The average number of we-chat steps in the exercise group was also significantly better than that in the control group (4,381±397 vs 3,478±342, P=0.035). Forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) in the exercise group were better than those in the control group, but the difference did not reach a statistically significant level [(1.76±0.19) L vs (1.60±0.28) L, P=0.084; (1.01±0.17) L vs (0.96±0.21) L, P=0.467].
CONCLUSIONS
Postoperative exercise rehabilitation training can improve exercise endurance and daily activity ability of patients with lung cancer complicated with COPD and promote postoperative rehabilitation.

Breast cancer and lung cancer are the two most common malignancies in China. With the continuous improvement of breast cancer diagnosis and treatment technology, the survival time of breast cancer patients has been prolonged, and the number of breast cancer patients with second primary lung cancer (SPLC) has increased. In addition, breast cancer is the most common primary cancer in female patients with SPLC, and SPLC is the main cause of death in this population. More and more physicians pay attention to this clinical phenomenon. This paper summarized the risk and risk factors of SPLC in breast cancer patients, and elaborated its pathogenesis, in order to provide a theoretical basis for the clinical management of breast cancer patients and achieve accurate early intervention as soon as possible.

Cryptococcus neoformans commonly causes opportunistic infections in immunocompromised patients, especially in patients with AIDS. CD4+ T-lymphocytopenia in AIDS indicates an increased risk of opportunistic infection and a decline in immunological function. Idiopathic CD4 T-lymphocytopenia (ICL) is characterized by depletions in the CD4+ T-cell subsets, without evidence of HIV infection. Immunodeficiency can exist in the absence of laboratory evidence of HIV infection, and T-cell subsets should be evaluated in patients who present with unusual opportunistic infections. We report a case of pulmonary cryptococcosis and lung cancer in a patient with persistently low CD4+ cell counts, without evidence of HIV infection.

BACKGROUND: Surgery has been considered the most effective and standard treatment modality in non-small cell lung cancer(NSCLC). However in stage IIIA lung cancer, the role of surgery is still controversial. To evaluate the role of surgery for stage IIIA NSCLC, we investigated the survival after surgery and the prognostic factors. MATERIAL AND METHOD: We evaluated 158 consecutive cases of stage IIIA NSCLC patients operated on between 1990 and 1996. There were 130 male patients and 28 female patients, and the mean age was 58.5 years. All patients except one underwent lung resection beyond lobectomy and extended mediastinal dissection. Postoperative adjuvant therapy were undertaken in 145(94.8%) patients. All patients(153) were followed and the mean follow-up period was 21.4months. RESULT: Twenty nine cases of the postoperative complications developed in 25 patients (15.8%). There were 5 operative mortality cases(3.2%) and the main cause of death was acute respiratory distress syndrome (ARDS). Local or distant recurrences developed in 84 patients(54.9%). The 5-year survival of 153 patients was 29.6% and the median survival time was 18.0 months. The 5-year survival of non N2 disease group(36.8%) was better than that of N2 disease group(26.6%)(p=0.35) and the 5-year survival of squamous cell carcinoma (38.1%) was better than that of adenocarcinoma(25.7%)(p=0.39) however there were no significant differences. Regarding the postoperative adjuvant therapy, in combined therapy group(84 patients), radiotherapy group(37 patients) and chemotherapy group(24 patients), the 5-year survival were 31.3%, 32.4%, and 14.6% respectively. There was no difference of survival between radiotherapy and combined therapy group(p=0.31), however the survival of the combined therapy group was better than the chemotherapy group(p=0.005). The survival of the complete resection group(31.9%) was better than the incomplete resection group(16.6%) however there was no significant difference(p=0.19). CONCLUSION: These observations indicate that the good 5-year survival(29.6%) in patients with stage IIIA NSCLC result from the agressive surgical treatment including extensive mediastinal nodes dissection.

Hemoptysis in patients with lung cancer is not uncommon and sometimes have dangerous consequences. Hemoptysis has been managed with various treatment options other than surgery and medicine, such as endobronchial tamponade, transcatheter arterial embolization and radiation therapy. However, these methods can sometimes be used only temporarily or are not suitable for a patient's condition. We present a case in which uncontrollable hemoptysis caused by central lung cancer was successfully treated by inserting a covered self-expanding bronchial stent. The patient could be extubated and was able to undergo further palliative therapy. No recurrent episodes of hemoptysis occurred for the following three months. As our case, airway stenting is a considerable option for the tamponade of a bleeding lesion that cannot be successfully managed with other treatment methods and could be used to preserve airway patency in a select group of patients.

BACKGROUNDIIIb-T(4) non-small cell lung cancer (NSCLC) is commonly considered a contraindication to surgery, although chemo-radiotherapy also achieves a poor survival rate. We reviewed our experience with T(4) NSCLC patients who underwent surgery to explore the indications and prognostic factors of surgical treatment of lung cancer invading the left atrium and great vessels.
METHODSWe investigated a cohort of 105 patients, 79 men and 26 women, who underwent surgery from May 1996 to July 2008. Their pathological staging was T(4)N(0)-(2)M(0). The median age was 59 years, ranging from 36 to 75 years. Patients were grouped based on invading sites: tumors invading the left atrium (LA group), tumors invading the superior vena cava (SVC group), and tumors invading the intrapericardial pulmonary artery (PA group). Patients were further characterized based upon the type of operation, complete resection and incomplete resection groups, and on the lymph node pathological status, N(0), N(1) and N(2) groups. We calculated the overall five-year survival rate.
RESULTSAll patients received resection of primary lesions, with partial resection of the left atrium in the LA group (n = 25), angioplasty of superior vena cava in the SVC group (n = 23) and intrapericardial ligation of the pulmonary artery in the PA group (n = 57). Complete resection was possible in 77 patients (73.3%). The overall survival rate of the 105 patients was 41.0% at 5 years; 36.0% for the LA group, 34.8% for the SVC group and 45.6% for the PA group. Pathological N status significantly influenced the overall 5-year survival rate; 61.5% for N(0), 51.1% for the N(1) and 11.8% for the N(2) groups (N(2) group versus N(0) group, P < 0.0001, N(2) versus N(1) group, P < 0.0001). Surgical resection also influenced survival; 49.4% for the complete resection group and 17.9% for the incomplete resection group (P < 0.0001). Cox regression analysis demonstrated that pathological N status was a significant independent predictor of prognosis.
CONCLUSIONSPathological N status is a significant independent predictor for survival of patients with IIIb-T(4) lung cancer invading the left atrium and great vessels. The completeness of resection has a significant influence on the overall 5-year survival rate. Surgery for T(4) lung cancer may be effective in patients without mediastinal lymph node involvement.

PURPOSE : To evaluate the compliance of patients who underwent complete resection of non-small cell lung cancer (NSCLC) with adjuvant chemotherapy. MATERIALS AND METHODS : Between January 2004 and May 2006, patients who underwent a complete resection for NSCLC were referred to oncologists for adjuvant chemotherapy. Three or 4 cycles of platinum-based adjuvant chemotherapy was then performed according to the protocol or the preference of the oncologists. RESULTS : Two hundred and thirty-two patients were enrolled in this study. The median age of the study group was 60.9 years and 76.7 % of the patients enrolled were male. 34.9%, 28.8% and 36.2% of the patients were in stage IB, II and III respectively. In addition, 142 of the patients (61.2%) completed all planned cycles, whereas 65 patients (28%) received no therapy. The causes of start failure for adjuvant chemotherapy consisted of decreased postoperative performance status (n=39), refusal (n=13) and distant metastasis at the initial follow-up (n=2). The causes of cessation during adjuvant chemotherapy included the occurrence of severe adverse effects (n=12), aggravation of the disease with newly developed metastasis (n=4) and others (n=6). The mortality related to the adjuvant chemotherapy was 1.3 % (n=3), all of the fatalities were due to pneumonia and sepsis. Univariate analysis showed that age, postoperative complications and pathologic staging were the significant factors that determined whether the adjuvant chemotherapy was completed. Multivariate analysis demonstrated statistically significant differences in compliance when age and pathologic staging were considered. CONCLUSION : Adjuvant chemotherapy for completely resected NSCLC was performed with satisfactory compliance in approximately 60% of the patients included in this study, and age plays an important role in the compliance of adjuvant chemotherapy. Elderly subsets will be examined to help determine the effect of age on compliance and outcome. In addition, the medical oncologist tended to complete the adjuvant chemotherapy for more advanced cases of lung cancer than for stage IB lung cancer

BACKGROUNDRadical lung resection is the best chance for cure in patients with anatomically resectable non-small cell lung cancer. A retrospective study was performed in an attempt to investigate general rules of major lung resection for non-small cell lung cancer in patients with compromised pulmonary function.
METHODSBetween June 2002 and December 2008, major lung resection was performed in 127 non-small cell lung cancer patients at our institution, who met the criteria of compromised pulmonary function defined as preoperative forced vital capacity < 50% of prediction or preoperative forced expiratory volume in one second < 50% of prediction. Clinical data of the patients were retrospectively reviewed.
RESULTSThe patients consisted of 108 males (85.0%) and 19 females (15.0%) with a mean age of 61.7 years. The morbidity rate was 44.1% (56/127) and the mortality rate was 4.7% (6/127). Multivariate analysis identified PaCO2 (P = 0.023, OR = 2.959, 95%CI 1.164 - 7.522), the percent predicted postoperative diffusing capacity of the lung for carbon monoxide (P = 0.001, OR = 0.176, 95%CI 0.064 - 0.480) and comprehensive preoperative preparation (P = 0.048, OR = 0.417, 95%CI 0.176 - 0.993) as the independent predictors of postoperative cardiopulmonary complications that were found in 45 cases. Overall 1-, 3- and 5-year survival rates were 90%, 55% and 37% respectively. For overall survival, multivariate analysis revealed that TNM staging (P = 0.004, OR = 1.585, 95%CI 1.154 - 2.178) was the only independent prognostic factor.
CONCLUSIONSOn the premise of integrated preoperative evaluation and comprehensive preoperative preparation, major lung resection provides an optimal therapeutic for selected non-small cell lung cancer patients with compromised pulmonary function. Hypercapnea and the percent predicted postoperative diffusing capacity of the lung for carbon monoxide < 40% could be considered as the independent predictive factors for operative risk in those patients.
