Progress in diagnosis and therapy of advanced pulmonary carcinoid

Pulmonary carcinoid (PC) is a rare low-grade malignant neuroendocrine tumor. Unlike other neuroendocrine tumors of the digestive tract, PC seldom causes hormone-related neuroendocrine symptoms, and the diagnosis mainly depends on the biopsy of the lesion. Besides, the immunohistochemical staining technique is an important supplement and a grading standard for pathological diagnosis. Surgery is the first choice for the treatment of early PC. However, the therapy of advanced PC which is the main problem perplexing most of clinicians is controversial and still facing severe challenges. Therefore, we will discuss the current progress of the diagnosis and therapy of advanced PC.

Analysis on Prognosis Factors of Rectal Carcinoid

Objective　To investigate the clinicopathological characteristics and factors influencing the prognosis of rectal carcinoid. Methods　Clinical data of 31 cases with rectal careinoid, which identified diagnosis through operation and pathologic examination from January 2003 to March 2010 were retrospectively reviewed. Primary tumors were classified by size （≤1.0 cm， 1.0-2.0 cm， and ＞2.0 cm）and muscularis invasion respectively, compared therapeutic effect of different groups. Results　Median age of 31 cases was 49 years (22-83 years). Median follow-up time was 36 months (15-86 months), follow-up rate was 80.6% （25 /31）. During the follow-up period, there were no cases with recurrence among the 15 patients with tumor size≤l.0 cm, 1 case recurred in the 7 patients with turmor size between 1.0 cm to 2.0 cm, and 2 cases died from postoperative liver metastasis among the 3 patients with tumor size＞2.0 cm.There were relations between the tumor size, invasion depth, and metastasis （P＜0.05）. Metastasis and invasion depth of tumor were possibility increment to follow the aggrandizement of the diameter of rectal carcinoid. Conclusion　The diameter of rectal carcinoid and muscularis invasion may be important factors affecting survival, which may be an important basis for the choice of operative mode.

RECTAL CARCINOID TUMOR (REPORT OF 26 CASES)

To investigate the pathological characteristics, diagnosis and treatment of rectal carcinoid tumors, 26 cases, which had been diagnosed and treated in our hospital from 1987 to 1997, were retrospectively analysed. The rectoscopic examination were taken in all 26 patients and final diagnosis were made by pathological examination, among them, 19 cases were treated with local resection or expensively local resection, 7 cases with radical operation because the diameter of tumor was beyond 2 cm. These patiests were followed up 1-10 years with 5 patients died. The authors consider that rectoscopic examination and biopsy are important method to diagnose rectal carcinoid tumors preoperatively, in addition, for suspicious case, argentation and immunohistochemistry staining should be further made besides routine HE staining. The operative treatment is the best therapy to this kind of disease, the choice of operative mode must be made according to the size, infiltration of the tumor, the condition of infiltrated lymph node and hepatic metastasis.

Clinical retrospective study of 20 patients with ectopic adrenocorticotropic hormone syndrome caused by bronchopulmonary carcinoid

Objective To investigate the clinical features, diagnosis, treatment and prognosis of ectopic adrenocorticotropic hormone (ACTH) syndrome caused by bronchopulmonary carcinoid. Methods Twenty patients (13 males and 7 females) with ectopic ACTH syndrome caused by bronchopulmonary carcinoid confirmed by surgical pathology were selected from March 2007 to May 2016 in our hospital. We collected and arranged the important clinical data of 20 patients and analyzed carefully. Results The mean age of 20 patients including 14 patients of typical carcinoid and 6 patients of atypical carcinoid was 38.85±15.31 years ranged 13-70 years. All patients had the typical clinical manifestation of Cushing's syndrome. All the thoracic lesions were located by thoracic computed tomography (CT) eventually. The concentration of serum cortisol and ACTH significantly decreased after surgery. Postoperative complications in 3 patients (15.00%) were severe pulmonary infection. Eighteen patients including 13 patients of typical carcinoid and 5 patients of atypical carcinoid were followed up. The median time of follow-up was 31.5 (12-122) months. There were 7 patients of stage Ⅰa, 1 patient of stage Ⅰb, 2 patients of stage Ⅱa and 8 patients of stage Ⅲa in the patients followed up. One patient underwent postoperative radiotherapy, and 4 patients with postoperative chemotherapy. During the follow-up period, one patient relapsed and there was no death. Conclusion Ectopic ACTH syndrome caused by bronchopulmonary carcinoid is a very rare disease. It is every difficult for clinicians to make early diagnosis and draw up plans of treatment without multidisciplinary collaboration. Chest CT is an important method of finding lesions and assessing the viability of surgery. Surgical treatment in early stage will be effective for this disease. And almost all of patients can achieve long-term survival after complete resection of tumors early.

Advancement in Liver Transplantation for Hepatic Metastasis from Neuroendocrine Tumor

Objective To summarize the application and advancement of liver transplantation for hepatic metastasis from neuroendocrine tumor. Methods Domestic and overseas publications on the study of liver transplantation for hepatic metastasis from neuroendocrine tumor in recent years were collected and reviewed. Results Liver transplantation can offer good relief of symptoms, long disease-free intervals, and potential cure in individual patients with hepatic metastatic tumor. Important selection criteria are well-differentiated tumors and a low proliferation rate (Ki67＜10%). Conclusion In carefully selected patients with metastatic neuroendocrine tumors, liver transplantation is an appropriate option.

胸腺类癌外科治疗的长期结果

Objective To investigate and evaluate the clinical manifestation, classification, surgical management and postoperative adjuvant therapy of thymic carcinoid, so as to improve the knowledge of the disease. Methods From January 1980 to January 2006, the outcome of surgery and follow-up of 18 cases of thymic carcinoid surgically intervened were retrospectively analysed. In this series, there were 2? exploratory thoracotomy, 2 partial or incomplete resection and 14 complete resections, which included 2 superior vena cava removal and reconstruction. The survival probabilities were calculated by the life tables, and a multivariable analysis of prognosis factors for thymic carcinoid was carried out using Cox regression model. Results Two patients who underwent exploratory thoracotomy died within one year and two years postoperatively respectively, 2 with partial or incomplete resection obtained temporary symptomatic improvement, 1 of 14 performed complete resections associated with Cushing’s syndrome died of septicemia in two weeks postoperatively, and the other 13 cases were in good condition by follow-up of 5 months to 15 years. The survival rate of 3, 5 and 10 years were 72.6%, 60.5% and 40.3%, respectively. According to Cox regression analysis, the factors of influence upon prognosis included lymph node metastasis(P=0047), pathological type(P=0.000), mode of resection (P=0.000) and postoperative adjuvant treatment(P=0018). Conclusion The thymic carcinoid is different from thymoma or thymic carcinoma, and there exist some difficulty in differential diagnosis. It is divided into typical and atypical thymic carcinoid in pathology, There are obvious differences in clinical manifestation and prognosis between typical and atypical carcinoid. The atypical thymic carcinoid has higher malignancy, frequent recurrence or metastasis, and poor prognosis. Complete resection of tumor with the involved surroundings could improve the long-term survival. The adjuvant radiotheraphy and chemotheraphy postoperatively would be benefit to the patients.

THE DIAGNOSIS AND TREATMENT OF RECTAL CARCINOID TUMORS

Fifteen patients with rectal carcinoid tumors were treated from 1975 to 1991. Before admision, nine patients (60%) had been misdiagnosed as polyps ,hemorrhoids or proctitis. Diagnosis may be delayed because of failure to recognize their charasteristics and by the negligeuce of doing digital examination or proctoscopy. Some aspects of the management of these tumors remain controversial. However, present-day treatment programs call for radical cancer resections only for lesions 2cm in diameter or larger, and local resections for all others. In reviewing this series of cases and other studies, we advocate that both the size of the lesion and the depth of tumor invasion should be taken as the criteria of surgical managements. If the tumor is 2cm in diameter, or smaller than that, local resection can be performed, but whenever the nuscularis propria is invaded, radical resection should be performed. Radical resection is bly indicated for tumors larger than 2cm.
