BACKGROUND: Tracheal, bronchus, and lung cancer (TBL) is a major cause of mortality and top contributor to productivity loss in large emerging economies such as the BRICS (Brazil, Russia, India, China, and South Africa). We examined the time trends of TBL mortality across the BRICS to better understand the disease burden in these countries and inform public health and healthcare resource allocation. METHODS: TBL mortality-related data between 1990 and 2019 were obtained from the Global Burden of Disease Study 2019 and analyzed using age-period-cohort models. Net drift (local drift) was used to describe the expected age-adjusted TBL mortality rate over time overall (each age group); the longitudinal age curve was used to reflect the age effect; the period rate ratios (RRs) were used to reflect the period effect; and the cohort RR was used to reflect the cohort effect. RESULTS: In 2019, there were 958.3 thousand TBL deaths across the BRICS, representing 46.9% of the global TBL deaths. From 1990 to 2019, the age-standardized mortality rate (ASMR) of TBL decreased in Russia, Brazil, and South Africa while increased in China and India, with the largest reduction reported in Russia (-29.6%) and the largest increase in China (+22.4%). India showed an overall increase (+15.7%) in TBL mortality but the mortality risk decreased among individuals born after 1990 (men) and 1995 (women). Although South Africa and Brazil experienced an overall decline in TBL mortality, their recent birth cohorts, such as Brazilian individuals born after 1985 (men) and 1980 (women), and South African men born after 1995, had an increasing TBL mortality risk. China has experienced an overall increase in TBL mortality, with the mortality risk rising among individuals born after 1995 for both men and women. Russia, which had the highest TBL mortality among the BRICS countries in 1990, has demonstrated significant improvement over the past three decades. CONCLUSIONS Over the past 30 years, the BRICS accounted for an increasing proportion of global TBL mortality. TBL mortality increased in older women in all the BRICS countries except Russia. Among the recent birth cohort, the risk of TBL mortality increased in Brazil, China, and South Africa. More effective efforts are needed in the BRICS to reduce the burden of TBL and help achieve the United Nation's Sustainable Development Goals.

BACKGROUND AND OBJECTIVEAdenoid cystic carcinoma is primary bronchopulmonary carcinoma with low malignancy, and 43 patients treated in the past 50 years in our hospital were retrospectively studied. The aim of this study is to discuss the clinical symptoms, pathologic characteristic and therapeutic method of primary tracheal or bronchuotracheal adenoid cystic carcinoma.

METHODSThis study summarized total 43 patients of primary tracheal or bronchus adenoid cystic carcinoma treated in our hospital from Jan. 1958 to Dec. 2007. Among them, 40 patients were treated by surgical resection, and 3 patients were treated by fiberoptic bronchoscope's interventional treatment.

RESULTSThe 1-yr, 3-yr, 5-yr survival rates of the 43 patients above were 100% (41/41), 89.5% (34/38), 87.1% (27/31), respectively.

CONCLUSIONPrimary tracheal or bronchus adenoid cystic carcinoma are rare and low malignancy carcinoma. The clinical symptoms of them are not typical. The best treatment is early detection and taking measures of operation plus radiotherapy. The other palliative treatment is fiberoptic bronchoscope's interventional treatment.

OBJECTIVETo review the experience in surgical treatment for tumors of trachea, carina and main bronchus.

METHODSFrom Jan. 1996 to Jun. 2004, 27 patients with tumor of trachea, carina or main bronchus underwent surgery including resection and reconstruction of trachea in 8, right/left pneumonectomy and carinal resection and reconstruction in 9 (6/3), right sleeve upper lobectomy and carnial resection with reconstruction of trachea and carina in 2, carina resection and reconstruction in 3, tumor removal through tracheal windows in 5. CPB (cardiopulmonary bypass) was used in 2 patients during surgery.

RESULTSThere were 3 peri-operative deaths caused by acute respiratory failure in 2 and severe postoperative bleeding in 1 case. After follow-up of more than 6 months, no death or post-operative complication occurred.

CONCLUSIONResection and reconstruction for patients with tumor of trachea, main bronchus or carina can be performed with excellent results using effective surgical and anaesthetic methods with or without CPB assistance.

OBJECTIVETo study the efficacy of treatment in 40 patients with primary tracheal carcinoma.

METHODSFrom 1970 to 2001, 40 patients with primary tracheal carcinoma treated in our hospital were retrospectively reviewed. Twenty-eight were male and 12 were female with median age of 47 years. The median interval from onset of symptoms to diagnosis was 10 months (1 - 60 months). Fifteen patients had adenoid cystic carcinoma, 14 squamous cell carcinoma, 8 adenocarcinoma, 2 small-cell carcinoma and 1 mucoepidermoid carcinoma. Thirty-two patients received operation plus adjuvant radiotherapy, 6 received radiotherapy alone and 2 received operation alone.

RESULTSThe median survival time for all patients was 40 months. The 1-, 5-, and 10-year survival rate was 86%, 59% and 29%, respectively. The 1-, 5-, and 10-year local control rate was 84%, 60% and 50%, respectively. Distant metastasis rate in 1, 5, and 10 years was 17%, 51% and 84%, respectively.

CONCLUSIONSurgical resection plus adjuvant radiotherapy is a reasonable mode of treatment. Despite late local recurrence after initial treatment, its intrinsic feature, excellent long-term palliation can be achieved after treatment.

OBJECTIVETo summarize the clinical experiences in treating primary tracheal tumors by surgery.

METHODSThe clinical data concerning 70 surgically treated patients between 1968 and 2001 were retrospectively analyzed.

RESULTSThere were 39 sleeve tracheal resections, 13 carinal resections, 10 lateral tracheal wall resections, 5 local enucleations, and 1 pneumonectomy. The tumors in 2 patients were unresectable. The morbidity rate was 31% (22/70) and operative 30-day mortality for resection with primary reconstruction was 8% (4/52). The tumors were benign in 14 and malignant in 56 cases. The most common malignant tumors were adenoidcystic carcinoma (45%) and squamous cell carcinoma (23%). The cases of benign tracheal tumors were followed up for an average of 5.7 years. After resection for malignant tumors, the overall 5- and 10-year survival rates were 64% (21/33) and 54% (14/26), respectively.

CONCLUSIONSSurgical resection is the most effective treatment of tracheal tumors. Tracheal resection and reconstruction is the treatment of choice for primary tracheal tumors. Benign tumors should be resected conservatively with preservation of tracheal parenchyma. The reduction of operative complications are key points of good surgical results.

BACKGROUND: Common treatment modalities for tracheal stenosis include conservative methods such as repeated balloon dilatation, removal of obstructive material through bronchoscopy and T-tube insertion as well as operative treatment methods. Recent advances in surgical approaches through tracheal resection and end-to-end anastomosis have been reported to give better functional and anatomical results. MATERIAL AND METHOD: Between March 1990 and July 2002, 41 patients who received tracheal resection and end-to-end anastomosis at Asan Medical Center, University of Ulsan were studied retrospectively. RESULT: The causes for tracheal resection and end-to-end anastomosis included 26 cases of postintubation stenosis, 10 cases of primary tracheal tumors (3 benign, 7 malignant), 1 case of endobronchial tuberculosis, 2 cases of traumatic rupture, and 2 cases of tracheal invasion of a thyroid cancer. Of the 41 patients who received tracheal resection and reconstruction, 29 received tracheal resection and end-to-end anastomosis, and 12 received laryngotracheal anastomosis with cricoid or thyroid cartilage resection. Four of these patients received supralaryngeal release. The average length of the resected trachea was 3.6+/-1.0 cm. Of the 41 patients who received tracheal resection and end-to-end anastomosis, 30 (73.2%) experienced no postoperative complications, and 8 (19.5%) experienced granulation tissue growth and/or minor infections which improved after conservative management. Good or satisfactory results were therefore achieved in 92.7%. Complications included repeated granulation tissue growth in 7, wound infection in 2, anastomotic site dehiscence in 2, restenosis resulting in dyspnea on exertion in 1, and repeated postoperative aspiration requiring retracheostomy in 1. There was no early postoperative mortality. There were 3 cases of hospital death. CONCLUSION: In cases of proper length of tracheal lesion, excellent results were obtained after tracheal resection and end-to-end anastomosis. But, granulation tissue growth is so serious complication, it is necessary for continuous study and efforts to prevent it.

OBJECTIVETo discuss the method of surgical treatment for well-differentiated thyroid carcinoma (WDTC) invading the laryngotrachea.

METHODSAccording to surgical procedure, 21 patients with WDTC invading the laryngotrachea were divided into tumor radical removal group (Group A, n = 5), tumor chisel group (Group B, n = 11) and tumor debulking group (Group C, n = 5).

RESULTSThe overall 3-, 5- and 7-year survival rates were 81.0% (17/21), 61.9% (13/21) and 42.9% with better result in Group A (P < 0.001) and Group B (P < 0.03) than in Group C, however, without any significance between Groups A and B (P > 0.05).

CONCLUSIONConservative operation should be considered in most patients with well differentiated thyroid carcinoma invading the laryngotrachea. Only in the presence of intraluminal invasion in the trachea causing hemoptysis and airway obstruction does it require radical operation.

BACKGROUND: There are various tracheal diseseas which cause the obstruction of the trachea: postintubation tracheal stenosis, tracheal cancer, thyroid cancer, endotracheal tuberculosis, et al. Recently surgical resection and reconstruction of the trachea has been adopted as the safe method for tracheal lesions. MATERIALS AND METHODS: We report our experience and results of resection and reconstruction for various obstructive tracheal lesions in 38cases from 1985 to 1996. Length of resection of the trachea was up to 6 cm. Twenty lesions were approached by cervical collar incision, 12 lesions by cervicosternal incision and 4cases needed transthoracic approach. Surgical procedures consisted of resection and tracheotracheal anastomosis in 32 cases, resection and laryngotracheal anastomosis in 6cases and in addition laryngeal release was necessary to release anastomotic tension in 3cases. RESULTS: The complications were 4 minor wound infections, 2 mild suture line granulomas, 1 vocal cord palsy, 2 pneumonias and 1 systemic candidiasis. Two patients who had poor consciousness and pnemonia and one who developed systemic candidiasis were expired after operation. CONCLUSION: We suggests resection and reconstruction of trachea is optimal procedure for up to 6cm long tracheal lesions. However, for the patients with poor consciousness or poor general conditions would be the conservative treatment preferred to the tracheal reconstruction because of high serious complications and mortalities.
