Zhao J, Bhatnagar V, Ding L, Atay SM, David EA, McFadden PM, Stamnes S, Lechtholz-Zey E, Wightman SC, Detterbeck FC, Kim AW. A systematic review of paraneoplastic syndromes associated with thymoma: Treatment modalities, recurrence, and outcomes in resected cases. J Thorac Cardiovasc Surg 2019; 160:306-314.e14. [PMID: 31982129 DOI: 10.1016/j.jtcvs.2019.11.052] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2019] [Revised: 11/05/2019] [Accepted: 11/06/2019] [Indexed: 12/13/2022]
Abstract
OBJECTIVE Paraneoplastic syndromes associated with thymomas remain incompletely understood. The objective was to examine the association between surgically resected thymomas and paraneoplastic syndromes over the past half century. METHODS A primary PubMed/MEDLINE search was used to identify published articles describing paraneoplastic syndromes associated with thymomas from 1960 to 2019. A secondary search identified additional articles referenced in the articles found in the primary search. Kaplan-Meier and log-rank test were used for time-to-event data analyses. RESULTS From 407 articles describing 507 patients, 123 different paraneoplastic syndromes were associated with thymoma. The 5 most common paraneoplastic syndromes were myasthenia gravis, pure red cell aplasia, lichen planus, Good syndrome, and limbic encephalitis. Complete or partial resolution of paraneoplastic syndrome symptoms after surgery was noted in 76% of patients, of whom 21% had a relapse or new paraneoplastic syndrome onset after surgery. The most common adjunctive therapy associated with resolution of paraneoplastic syndrome was corticosteroids (30%). For all patients after surgery, thymoma recurrence was observed in 17% of cases, whereas recurrence of paraneoplastic syndrome was observed in 34% of cases, and both were observed in approximately 11% of cases. The 5- and 10-year overall survivals were 78% and 66%, respectively. Improved overall survival was associated with patients who had total resolution from paraneoplastic syndrome. CONCLUSIONS A comprehensive assessment of publications over the past half century suggests that a multimodal treatment approach that includes surgical resection of thymomas is able to achieve paraneoplastic syndrome resolution in a majority of patients. Onset of new paraneoplastic syndromes after surgery is associated with the recurrence of the first paraneoplastic syndrome, and resolution of paraneoplastic syndrome is associated with improved overall survival.

Abstract
Thymic malignancies represent a wide range of clinical, histological and molecular entities, with probably considerable heterogeneity even among tumors of the same histotype. Systemic chemotherapy with cisplatin-based regimens continues to represent the standard of care in metastatic or inoperable refractory/recurrent diseases and ADOC regimen (including cisplatin, doxorubicin, vincristine and cyclophosphamide) demonstrated the longer overall response rate and median survival in the first line setting, although no randomized trial is available; and there is still a lack of standard treatment after first-line failure. To date research efforts are focused on translational studies on molecular pathways involved in thymic tumors carcinogenesis, aimed to better understand and predict the efficacy of chemotherapy and targeted therapy. Recent molecular characterization includes identification of a number of oncogenes, tumor suppressor genes, chromosomal aberrations, angiogenic factors, and tumor invasion factors involved in cellular survival and proliferation and in tumor growth. The use of biologic drugs is currently not recommended in a routine practice because there are limited data on their therapeutic role in thymic epitelial tumors. Because of the lack of data from adequate-sized, prospective trials are required for validation and the enrolment of patients with advanced disease into available clinical trials has to be encouraged.

Abstract
Thymic neoplasms constitute a broad category of rare lesions with a wide spectrum of pathologic characteristics and clinical presentations which therefore require a high index of suspicion to diagnose. The natural history of the disease is seldom predictable, anywhere from an indolent to an aggressively malignant course. Although the classification and staging of these lesions are complex and controversial, complete radical surgical resection remains the gold standard of therapy. Radiation and chemotherapy are important elements of the multimodality approach to treating these patients and it is important for thoracic surgeons to work closely with their colleagues in other disciplines in the management of and future research endeavors in thymic neoplasm. In this review, we discuss the evaluation of the patient with an anterior mediastinal mass, the classification and staging of thymic neoplasms, the role of surgery, radiation and chemotherapy in treating this disease, as well as future directions in research for novel targeted therapies.

Abstract
OBJECTIVES Myasthenia gravis (MG) is an immune-mediated disorder associated with autoantibodies against postsynaptic nicotinic acetylcholine receptors at neuromuscular junctions. Rituximab, a monoclonal antibody specific for CD20, is used primarily to treat B-cell non-Hodgkin lymphoma. Although it has been used for treatment of a number of autoimmune diseases, there is limited experience in MG. METHODS Three patients with refractory MG (2 with concurrent thymoma) were given rituximab. RESULTS Symptoms stabilized and reductions in immunosuppressive medications were tolerated for extended periods, without adverse effects or infectious complications. CONCLUSIONS These observations support the concept that rituximab may be helpful for the treatment of MG. Remissions in patients with or without thymoma are achievable with rituximab given in combination with commonly used modalities. Furthermore, rituximab is not necessarily contraindicated for the treatment of MG in patients being treated for thymoma. Controlled studies are called for to define its role in the treatment of refractory MG.

Abstract
Chemotherapy has an important role in the treatment of advanced thymic tumors. Early stage tumors are successfully treated with surgery. Locally advanced tumors (Masaoka stage III and IVA) are often treated with combined modality treatment including surgery, radiation, and chemotherapy. For patients with curable thymic tumors, the ability to attain a complete resection is a critical prognostic factor. Locally advanced tumors have a relatively high risk of recurrence and decreased rates of long-term survival. A multimodality approach including induction chemotherapy and postoperative radiation therapy can improve complete resection rates and long-term outcomes. Thymic tumors are chemoresponsive with optimal responses achieved with cisplatin-based combination chemotherapy. Chemotherapy with radiation can result in long-term progression-free survival for patients with locally advanced disease who remain inoperable following induction therapy. Patients with disseminated (stage IVB) thymic tumors can also have significant disease response and palliation of symptoms when treated with chemotherapy. Octreotide and corticosteroids also have shown efficacy. For best results, it is important that thoracic surgeons, radiation oncologists, and medical oncologists work together to obtain the best local control of tumor and optimal treatment of metastases.

Abstract
This article provides a unique perspective on thymoma by describing the clinical scenarios from 2 diverse patient populations followed by an update. A comparative chart review was conducted on patients diagnosed at 2 university-based hospitals, 1 in the United States and 1 in Thailand. A comprehensive review of the literature was then performed through MEDLINE for articles between 1980 and 2002. During the last 23 years, charts from 16 patients at each institution were available for review. The most common presenting symptoms were myasthenia gravis (47%), dyspnea (25%), and chest discomfort (19%) and are similar to those reported in the literature. The primary treatment of stages I-III disease included surgery with or without radiation. Trimodality therapy with surgery, radiotherapy, and chemotherapy was pursued in 43% of patients with stage IV disease in the United States, whereas no patients from Thailand underwent this regimen. Median overall survivals were 124 and 76 months in the Thai and the US groups, respectively (P = 0.76). No major differences in the clinical features were observed between the 2 institutions, although a trend toward more advanced disease was seen in the United States. Surgery and radiation remain the backbone of treatment, but the role for chemotherapy is increasing.

Abstract
Classification, understanding of the pathophysiology, and treatment options of thymoma have changed during recent years. It is hoped that novel strategies will lead to a survival benefit in these patients. It has become clear that patients with thymoma are best treated with multimodality therapy. In this review, a pathologist, an immunologist, a surgeon, a radiotherapist, a pneumologist, and oncologists discuss the current status of classification and strategies for the treatment of patients with thymoma.

Abstract
PURPOSE To evaluate single-agent ifosfamide in the treatment of invasive thymoma. PATIENTS AND METHODS Fifteen patients (eight male and seven female) with histologically confirmed invasive thymoma were treated. The median age was 48 years (range, 23 to 76 years). Four patients had stage III disease, seven patients had stage IVa disease, and four patients had stage IVb disease. The most common histologic type was lymphoepithelial. Seven patients had received prior treatment, including one patient who received chemotherapy. Ifosfamide 1.5 g/m(2) was given on days 1 to 5, with mesna as a uroprotector. RESULTS Thirteen patients were assessable for response. Five complete responses (38.5%; 95% confidence interval [CI], 17.7% to 64.5%) and one partial response (7.7%; 95% CI, 1.4% to 33.3%) were seen. The median duration of complete response was 66+ months (range, 25 to 87 months), and the estimated survival rate 5 years after ifosfamide treatment was 57% (SE, 32% to 79%). The most frequent toxicities were nausea, vomiting, and leucopenia, but these were well tolerated. CONCLUSION Single-agent ifosfamide possesses significant activity against invasive thymoma and is comparable to currently used combination regimens. The inclusion of ifosfamide in combination therapy, particularly in place of cyclophosphamide in regimens such as cisplatin, doxorubicin, and cyclophosphamide, needs to be evaluated.

Abstract
Invasive thymoma recently has been shown to be sensitive to combination chemotherapy and in some cases to be relatively indolent. Two cases of extensive thymoma which responded to primary treatment with a combination of a platinum compound (carboplatin or cisplatin), doxorubicin (Adriamycin), and cyclophosphamide (or PAC) are described. Tumor progression occurred 14 (case 1) and 60 months (case 2) after completion of initial PAC therapy and was treated with the same regimen resulting in a second remission, which lasted 6 months in case 1 and is continuing at 8 months in case 2. Similar reports of secondary responses using the same chemotherapy have been described in breast, lung, and ovarian cancers, as well as in Hodgkin's lymphomas. Our observations suggest that retreatment with the same platinum-based regimen should be considered in patients who have progressive thymomas following a previous chemotherapeutic response and a disease-free interval of greater than 12 months.

Abstract
OBJECTIVES To analyze the prognostic factors influencing the survival of patients with thymoma, clinical characteristics, treatment modalities and survival of patients were evaluated. The efficacy of chemotherapy was also determined. METHODS Retrospective study was done on one hundred patients whose diagnosis was confirmed pathologically at Seoul National University Hospital from 1981 to 1994. The staging was carried out according to the Masaoka system. Survival rate was calculated by the Kaplan-Meier method and prognostic factors were analyzed by a multivariate analysis (Weibull model). RESULTS The stage of 100 patients was as follows: Stage I-50, II-6, III-27, IV A-10, IV B-7. The overall survival rates at 5 and 10 years after diagnosis were 73.1% and 58.7%, respectively. The 5-year survival differences, according to various prognostic factors, were as follows: 1) Stage: I-92.8%, II-100%, III-71.6%, IVA-25.9% and IVB-32.9% (p = 0.0029). 2) Age: < 60 years-79.5% and > or = 60 years-41.5% (p = 0.0489). 3) Extent of resection: Total patients: complete resection-87.6% and incomplete resection-50.5% (p > 0.05) Stage III: complete resection-66.7% and incomplete resection-75.5% (p > 0.05) 4) Myasthenia gravis: present-71.6% and absent-74.9% (p > 0.05) Seventeen patients were treated with a combination chemotherapy of Cyclophosphamide, Adriamycin and cisplatin(CAP). Two complete responses and seven partial responses (overall response rate of 53%) were observed with a median response duration of fourteen months. Combination chemotherapy with CAP was effective. CONCLUSIONS Stage and age were the independent prognostic factors in patients with thymoma. However, the presence of myasthenia gravis or the extent of resection in stage III patients was not associated with the survival time.

Abstract
BACKGROUND The authors retrospectively analyzed 87 patients with malignant thymoma treated at M.D. Anderson Cancer Center between 1951 and 1990. The analysis examined the clinical stages, histologic types, and treatment modalities and attempted to determine if chemotherapy had an impact on survival. METHODS The patients were divided into three groups by their year of treatment and treatment modality. Patients treated between 1951 and 1975 were in Group I; patients treated between 1976 and 1980 were in Group II; and patients treated between 1981 and 1990 were in Group III. Most of the patients (18 [72%] in Group I; 16 [62%] in Group II; and 18 [50%] in Group III) had surgical resection alone or with radiotherapy. Patients with advanced-stage disease in Group I received single-agent chemotherapy, whereas patients with advanced-stage disease in Group II received a different, combination chemotherapy regimen, and those in Group III were treated primarily with cisplatin- and doxorubicin-based combination chemotherapy, e.g., the cyclophosphamide doxorubicin, and cisplatin with or without prednisone. The 17 patients treated with cisplatin with or without prednisone were separately evaluated for survival according to their response. RESULTS Twenty-eight patients (5 [20%] in Group I; 6 [23%] in Group II; and 17 [47%] in Group III) received chemotherapy alone or after surgery or radiotherapy. The cisplatin with or without prednisone regimen was used in 17 Group III patients for initial treatment or for relapse. The overall response rate among the patients receiving the cisplatin with or without prednisone regimen was 64%; 6 (35%) had a complete response, and 5 (29%) had a partial response. Thirty-one (36%) of the 87 total patients had 45 recurrent tumors; the lung (29%), pleura (22%), and mediastinum (18%) were the most common sites of recurrence, whereas bone was the most common distant metastatic site. The 5-year survival rate was 70% in patients with Stage I disease, 71% in patients with Stage II or III disease, and 46% in patients with Stage IV disease. The 10-year survival rate was 70% in patients with Stage I disease, 47% in patients with Stage II or III disease, and 21% in patients with Stage IV disease. Statistical analysis indicated a significant difference among the survival rates of patients with noninvasive Stage I, invasive Stage II plus III (P = 0.033), and Stage II plus III and IV tumors (P = 0.056), but not between patients with Stage II or III tumors. Patients with a major response to the cisplatin with or without prednisone regimen had a significant survival improvement compared to those with no response (P = 0.002, log-rank test). CONCLUSIONS Because thymoma is a chemosensitive tumor and frequently recurs in patients with Stage II or greater disease, chemotherapy carries a potential survival benefit and should be incorporated into the multimodality approach to prolong disease-free survival.

Abstract
From 1972 to 1990, we treated eight cases of thymic carcinoma (6 squamous cell and 2 small cell carcinomas). According to the classification by Masaoka et al., they consisted of one stage I, four stage III, one stage IVa, and two stage IVb. A complete resection of the primary tumour could be done in only three patients; the others had diagnostic biopsy and then radiation treatment. Four of five patients had a prolonged regression of the primary tumors after irradiation at 40-61.2 Gy. Six patients suffered from extrathoracic metastases. All patients received systemic chemotherapy with different regimens to counter either metastatic or locally recurrent lesions. Only two patients (with a regimen including cyclophosphamide, doxorubicin, and vincristine) obtained a partial response. The median survival of the eight patients was 70 months after surgical operation. The identification of an effective drug combination may thus improve the long-term prognosis of thymic carcinoma since radiotherapy is able to control primary lesions, even in the case of unresectable advanced disease.

Abstract
BACKGROUND Nocardia asteroides is an opportunistic infection caused by an aerobic actinomycete, which, in the immunocompromised host, can be associated with severe invasive disease with a predilection for the brain. METHODS AND RESULTS The authors describe a 62-year-old man with a malignant thymoma that was clinically responsive to oral prednisone. N. asteroides sepsis subsequently developed, leading to his death. CONCLUSIONS Nocardiosis should be considered a potential pathogen in this immunocompromised setting.

Abstract
Myasthenia gravis (MG) occurs in up to 44% of patients with thymoma. Thirty-three percent of these neoplasms are invasive but extrathoracic disease is rare. Recently, we saw a patient with MG and recurrent, metastasizing mixed lymphoepithelial thymoma, whose disease was resistant to combination chemotherapy and radiotherapy but who responded dramatically to treatment with daily glucocorticoids. Thus, therapy with daily glucocorticoids should be considered in the treatment of invasive or metastatic thymoma associated with MG, including when conventional surgery, radiotherapy, and chemotherapy have failed.

Abstract
A review of the evaluation, treatment, and end results for 52 patients with thymoma treated at The University of Texas M.D. Anderson Cancer Center (1950-1984) is presented. The objective of the study was to examine the influence of a number of clinical characteristics on survival, including histologic and staging classifications, associated diseases, symptom status, and treatment. Forty-nine patients (94%) underwent surgical exploration; 13 were stage I, 12 were stage II, and 24 were stage III. Complete resection was accomplished in all of the stage I and II groups and in 6 of the stage III patients. An asymptomatic history, surgical stage I disease, lymphocytic thymoma cell type, and complete resection favorably influenced prognosis. The cumulative 5-year survival rate for all patients was 40%. No patient with stage I thymoma had recurrent disease, however, there were 9 recurrences (50%) in the completely resected stage II/III patients, six of whom remained disease-free following treatment with radiotherapy, chemotherapy, or a combined approach.

Abstract
The authors report on combination chemotherapy in 22 patients (seven men, 15 women; age 20-67, median 38.5 years) with incompletely resected invasive thymoma. Twelve of 22 patients have had prior radiotherapy of the tumor (four of 12 local failure, eight of 12 remote metastases). By subsequent chemotherapy five of 12 obtained complete remission (CR). One of them died by relapsed tumor, another by an intercurrent infection. At 5 years after diagnosis the survival rate of the 12/22 patients was 33% (Kaplan-Meier). Ten of 22 patients received chemotherapy as primary treatment of incompletely resected thymoma. Four of 10 obtained CR. One of them was lost during follow-up, the others received adjuvant irradiation of the mediastinum and are free of disease. Two of ten obtained partial remission (PR), but relapsed within 6 months after chemotherapy. At 3 years after diagnosis the survival rate of the 10/22 patients was 34%. Thirteen of 22 patients received cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or CHOP/bleomycin as first chemotherapeutic regimen. Five of them achieved CR. Cyclophosphamide, vincristine, and prednisone (COP) or COP plus procarbazine (COPP) was administered to six of 22. Three of them obtained a CR and one a PR. In an alternating manner COPP and Einhorn regimens were given to two of 22, one of which had a CR. In one of 22 the doxorubicin, bleomycin, cisplatin, prednisone (BAPP) regimen was followed by a PR. The authors conclude that combination chemotherapy is effective in the first-line postsurgical treatment of incompletely resected thymoma and also in the treatment of local or metastatic relapses after radiotherapy.
