BACKGROUND: The incidence of testicular carcinoma in the United States has increased significantly over the last two decades. Germ cell tumors form the majority of malignant testicular tumors. With advances in diagnosis and therapeutic approaches, germ cell tumors are now highly sensitive to treatment, providing long-term survival. It has been speculated that the incidence of bilateral germ cell tumors may increase due to the improved survival of patients with unilateral germ cell tumors. In this report, the authors present a study of bilateral germ cell tumors of the testis in men who were treated at The University of Texas M. D. Anderson Cancer Center over a 20-year period with emphasis on their incidence, histologic features, and clinical features. METHODS: Between 1978 and 1999, 2431 patients with testicular germ cell tumors were treated at The University of Texas M. D. Anderson Cancer Center. Among these, 24 patients with bilateral germ cell tumors were identified. Clinical records and all available pathology slides of the tumors were reviewed. RESULTS: The overall incidence of bilateral germ cell tumors in the patients with testicular germ cell tumors was 1% (24 of 2431 patients). The incidence was 1.8% (14 of 776 patients) in patients with seminoma and 0.6% (10 of 1655 patients) in patients with nonseminomatous germ cell tumors. Patients with seminoma who were age = 30 years at the time of initial diagnosis had a higher incidence of bilateral tumors compared with older men. Twenty of 24 patients with bilateral germ cell tumors had metachronous tumors, and 4 patients had synchronous tumors. Among the patients with metachronous tumors, 70% of second tumors occurred within 5 years; the longest interval between the first and second tumors was 15 years. The outcome of patients with bilateral germ cell tumors was excellent; only 1 of 24 patients died of metastatic disease. CONCLUSIONS: The overall incidence of bilateral testicular germ cell tumors was 1% in patients who were treated at The University of Texas M. D. Anderson Cancer Center over the past two decades. The incidence of bilateral germ cell tumors was related to the histologic type of the initial tumor and to the patient's age at initial presentation in patients with seminoma. Thus, patients in the second or third decade of life who presented with seminomas as their initial tumor were more likely to develop a second germ cell tumor compared with patients in the fourth or fifth decade of life. These findings have potentially important implications for clinical management by identifying a population of patients with germ cell tumors who are at risk of developing a second tumor and also for studying risk factors of bilateral germ cell tumors of the testis. 相似文献

BACKGROUND: Adenoid cystic carcinoma of the sinonasal tract is a rare cancer that accounts for 10% of all malignancies at this site. The objective of the current study was to evaluate prognostic factors, treatment outcomes, recurrence patterns, and survival rates for sinonasal adenoid cystic carcinoma. METHODS: A retrospective chart review was performed at an academic tertiary referral center. Between 1990 and 2004, 105 patients were evaluated for adenoid cystic carcinoma of the sinonasal tract at a single institution. Demographics, presentation, anatomic site, Tumor, Lymph Node, Metastasis (TNM) classification, pathology, treatment, recurrences, and survival were evaluated. RESULTS: One hundred five patients with adenoid cystic carcinoma were evaluated, including 58 women and 47 men. Their median age was 50 years, and the mean follow-up was 47 months. The maxillary sinus (47%) and the nasal cavity (30%) were the most common primary tumor sites. The majority of patients presented with T3/T4 (76.7%), N0 (98%), M0 (97%) disease. Eighty-four percent of patients underwent surgery and received postoperative radiation as treatment for their primary disease. The local recurrence rate was 30%, and the distant metastases rate was 38%. The 5-year overall survival and disease specific survival rates were 62.9% and 70.9%, respectively. CONCLUSIONS: Adenoid cystic carcinoma of the paranasal sinuses is a rare disease, and the ideal treatment paradigm has yet to be defined. The current data suggested that surgical resection with postoperative radiation therapy offers durable local control and compares favorably with historic data. Although local recurrences develop in a significant percentage of patients, survival from this disease exceeds that of other sinonasal malignancies. 相似文献

Prognostic factors and treatment of patients with T-cell non-Hodgkin lymphoma: the M. D. Anderson Cancer Center experience 总被引:9,自引:0,他引:9
BACKGROUND: T-cell non-Hodgkin lymphomas (T-NHL) are more aggressive and patients have a poorer prognosis compared with patients with the corresponding B-cell lymphomas. Although intensive treatments have been developed, it is unknown whether they are more effective than CHOP chemotherapy (cyclophosphamide, doxorubicin, oncovorin, and prednisone). METHODS: The authors' retrospective study evaluated the clinical outcome of 135 previously untreated patients with T-NHL who were treated at The University of Texas M. D. Anderson Cancer Center (Houston, TX) between 1996 and 2002. Lymphomas with T-cell histologies with the exception of mycosis fungoides were included. RESULTS: The estimated median overall survival was 46 months. Thirty-seven percent of the patients received CHOP therapy, 48% received intensive therapy, and 15% received other therapy. The estimated 3-year overall survival rates were 62% for the patients treated with CHOP therapy and 56% for the patients who received intensive therapy. After the exclusion of patients with anaplastic large cell lymphoma (ALCL), who are known to have a better prognosis than patients with other T-NHLs, the estimated 3-year overall survival rates were 43% for the patients treated with CHOP therapy and 49% for the patients who received intensive therapy. Parameters that may be independent prognostic factors for survival in T-NHL, excluding ALCL, included ECOG performance status > or = 2, beta-2-microglobulin level > 2 mg/L, lactate dehydrogenase level higher than normal, bulky disease > or = 7 cm, and a higher international prognostic index and tumor score. CONCLUSIONS: The current study data suggested that patients treated with intensive therapies did not fare better than those treated with CHOP therapy. New treatment regimens need to be developed for patients with T-NHL. 相似文献

BACKGROUND: Adult Burkitt-type lymphoma (BL) and acute lymphoblastic leukemia (B-ALL) are rare entities composing 1% to 5% of non-Hodgkin lymphomas NHL) or ALL. Prognosis of BL and B-ALL has been poor with conventional NHL or ALL regimens, but has improved with dose-intensive regimens. METHODS: To evaluate the addition of rituximab, a CD20 monoclonal antibody, to intensive chemotherapy in adults with BL or B-ALL, 31 patients with newly diagnosed BL or B-ALL received the hyper-fractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone (hyper-CVAD) regimen with rituximab. Their median age was 46 years; 29% were 60 years or older. Rituximab 375 mg/m(2) was given on Days 1 and 11 of hyper-CVAD courses and on Days 1 and 8 of methotrexate and cytarabine courses. RESULTS: Complete remission (complete response [CR]) was achieved in 24 of 28 (86%) evaluable patients; 3 had a partial response, and 1 had resistant disease. There were no induction deaths. The 3-year overall survival (OS), event-free survival, and disease-free survival rates were 89%, 80%, and 88%, respectively. Nine elderly patients achieved CR with all of them in continuous CR (except 1 death in CR from infection), with a 3-year OS rate of 89%. Multivariate analysis of current and historical (those treated with hyper-CVAD alone) groups identified age and treatment with rituximab as favorable factors. CONCLUSIONS: The addition of rituximab to hyper-CVAD may improve outcome in adult BL or B-ALL, particularly in elderly patients. 相似文献

BACKGROUND: Hodgkin transformation is a rare complication of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). In this study, the authors assessed the incidence, presenting characteristics, and outcomes of patients with CLL/SLL who developed Hodgkin lymphoma (HL). METHODS: An electronic database search of patients with CLL/SLL who presented at The University of Texas M. D. Anderson Cancer Center Department of Leukemia between 1975 and 2005 was performed. RESULTS: Among 4121 patients with CLL/SLL, 18 patients (0.4%) developed HL. Presenting features included B-symptoms (67%), lymph node enlargement (79%), splenomegaly (43%), hepatomegaly (29%), hypercalcemia (6%), infection (6%), and mental status changes (6%). The median age was 72 years (range, 49-81 years), and there was a male preponderance (78%). The median time from CLL to HL diagnosis was 4.6 years (range, 0-12.9 years). Fourteen patients (78%) had been previously treated for CLL/SLL. Ten patients (56%) had received >1 prior therapy. The median beta2-microglobulin level was 4.5 mg/L, and the median lactate dehydrogenase level was 610 IU/L. Epstein-Barr virus (EBV) was positive by in situ hybridization for EBV-encoded RNA in 3 of 4 tested patients. Fourteen patients (78%) received chemotherapy. The overall response rate was 44% (complete response rate, 19%). The median overall survival duration was 0.8 years (range, 0.03 years-6.7+ years). The median failure-free survival (FFS) duration was 0.4 years. CONCLUSIONS: The rates of response, survival, and FFS in patients with Hodgkin transformation of CLL/SLL were inferior to those reported in patients with de novo HL and were similar to those in patients with Richter syndrome. 相似文献

BACKGROUND: The objective of this study was to estimate the incidence and describe distribution, clinical presentation, and prognosis of brain metastases in patients with prostate carcinoma who were seen at The University of Texas M. D. Anderson Cancer Center (MDACC). METHODS: The authors reviewed the charts of 16,280 patients with prostate carcinoma in the MDACC patient data base. Of 131 patients with craniospinal metastases confirmed by neuroimaging (n=53 patients) or autopsy (n=78 patients), 103 of 16,280 patients (0.63%) had parenchymal metastases. RESULTS: The median patient age at diagnosis was 64 years (range, 16-85 years). The median interval from the diagnosis of prostate carcinoma to the detection of brain metastasis was 35 months for patients with adenocarcinoma and 48 months for patients with small cell carcinoma (SCC). Confusion, headache, and memory deficits were the most frequent initial symptoms. Eighty-six percent of patients had single lesions, and 14% of patients had > or = 2 lesions. Metastases were supratentorial in 81 of 103 patients (76%), infratentorial in 22 of 103 patients (21%), and both supratentorial and infratentorial in 3 of 103 patients (3%). SCC and cribriform subtypes were more likely than adenocarcinoma to metastasize to the brain (relative risk, 20.36; 95% confidence interval, 9.91-41.84). Regardless of histology, the median survival in untreated patients was 1 month compared with 3.5 months in patients who were treated with radiotherapy. Patients who underwent stereotactic radiosurgery (n=5 patients) had a longer median survival (9 months). Survival was not affected by supratentorial or infratentorial location of metastases. CONCLUSIONS: Brain metastasis from prostate carcinoma is a rare, terminal event with death in <1 year frequently due to advanced, systemic disease. The majority of metastases were single and supratentorial. The most common clinical presentation was nonfocal neurologic symptoms related to intracranial hypertension. A better understanding of the biology of prostate carcinoma will help clarify the basis for its metastasis to the brain. 相似文献

Purpose: To review the 20 years of experience at M. D. Anderson Cancer Center with a combined-modality approach against inflammatory
breast carcinoma. Patients and methods: A total of 178 patients with inflammatory breast carcinoma were treated in the past 20 years at M. D. Anderson Cancer Center
by a combined-modality approach under four different protocols. Each protocol included induction chemotherapy, then local
therapy (radiotherapy or mastectomy), then adjuvant chemotherapy, and, if mastectomy was performed, adjuvant radiotherapy.
Chemotherapy consisted of 5-fluorouracil, doxorubicin, and cyclophosphamide (FAC) with or without vincristine and prednisone
(VP). In protocol D, patients received an alternate adjuvant chemotherapy regimen, methotrexate and vinblastine (MV), if they
did not have a complete response (CR) to induction chemotherapy. Results: The median follow-up of live patients in group A was 215 months, in group B 186 months, in group C 116 months, and in group
D 45 months. An estimated 28% of patients were currently free of disease beyond 15 years. At the time of analysis, 50 patients
were alive without any evidence of disease. A further 12 patients died of intercurrent illness, and 15 patients were followed
beyond 10 years without recurrence of disease. Among initial recurrence, 20% of patients had local failure, 39% systemic failure,
and 9% CNS recurrence. Initial response to induction chemotherapy was an important prognostic factor. Disease-free survival
(DFS) at 15 years was 44% in patients who had a CR to induction chemotherapy, 31% in those who had a partial response (PR),
and 7% in those who had less than a PR. There was no improvement in overall survival (OS) or DFS among patients who underwent
alternate chemotherapy (MV) compared with those who did not. Using surgery and radiotherapy as opposed to radiotherapy alone
as local therapy did not have an impact on the DFS or OS rate. Conclusion: These long-term follow-up data show that with a combined-modality approach a significant fraction of patients (28%) remained
free of disease beyond 15 years. In contrast, single-modality treatments yielded a DFS of less than 5%. Thus, using combined-modality
treatment (chemotherapy, then mastectomy, then chemotherapy and radiotherapy) is recommended as a standard of care for inflammatory
breast carcinoma.

Small cell carcinoma of the esophagus: the University of Texas M. D. Anderson Cancer Center experience and literature review 总被引:17,自引:0,他引:17
BACKGROUND: Small cell carcinoma of the esophagus is a rare disease with aggressive behavior and poor prognosis. Multidrug chemotherapy remains the treatment of choice given the systemic nature of the disease. Radiotherapy has been used concurrently with chemotherapy to enhance local control. The role of surgery in patients with limited disease is controversial. Limited data exist regarding the pathologic response of the tumor to chemoradiotherapy. The goal of the current study was to analyze the outcome of 8 patients treated at the M. D. Anderson Cancer Center, with particular focus on the histologic findings of the resected specimens. METHODS: Patient records were reviewed for demographics, presenting symptoms, diagnostic modalities, disease stage, treatment, and outcome. RESULTS: Two of eight patients had metastatic disease at the time of diagnosis and received combination chemotherapy. Six patients had limited stage disease. Four received combined modality treatment including esophagectomy, and two received radiotherapy only. All four patients who underwent esophagectomy had pure small cell carcinoma histology at diagnosis and received preoperative combination chemotherapy with or without radiotherapy. None of the four patients achieved a pathologic complete remission. Two patients had residual small cell carcinoma; one patient had squamous cell carcinoma and one adenocarcinoma. The median overall survival for the group of patients was 12.5 months (range, 5-57 months). CONCLUSIONS: In selected patients with limited stage disease, surgery with curative intent should be considered as part of multimodality treatment. 相似文献

The use of primary systemic (neoadjuvant) therapy has become widespread in the treatment of patients with locally advanced and operable breast cancer. The utilization of this therapeutic approach provides several advantages. By monitoring changes in the dimension of the tumor, efficacy can be evaluated or assessed in vivo; unnecessary toxicity can be avoided by allowing the physician to discontinue ineffective therapy. Furthermore, downstaging of a tumor through primary therapy may allow for breast-conserving surgery in patients with large operable breast cancer and render inoperable tumors resectable. Also, the use of primary therapy can provide a pathological complete response, which correlates with prolonged periods of remission. Treatment with FAC (5-fluorouracil/doxorubicin/cyclophosphamide) has proven to be effective as neoadjuvant therapy in locally advanced breast cancer in several trials. More recently, the integration of taxanes into primary therapy regimens has been explored with promising results. Studies have suggested that the use of primary therapy, particularly the use of FAC, should perhaps become the standard in patients with locally advanced disease. The history of clinical trials focusing on primary therapy in breast cancer at the M. D. Anderson Cancer Center will be reviewed. 相似文献

BACKGROUND: Recently, endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has emerged as a diagnostic adjunct for small pancreatic lesions and abdominal and mediastinal lymph node diseases.DESIGN: During a 21-month period, we performed 179 EUS-FNAs in 166 consecutive patients; these data are the subject of this study. An average of 2.6 needle passes were obtained and aspiration was performed most commonly in the pancreas (162 cases, 91%). The FNA smears were reviewed using six diagnostic categories (negative for malignancy/nondiagnostic [NND], atypia, suspicious for malignancy, benign tumor/cyst, neuroendocrine neoplasm [NEN], and carcinoma). The review diagnosis was correlated with the histologic diagnosis made on resection or surgical biopsy specimens in 70 cases. Up to 17 months of clinical follow-up were sought for the cases with a negative or inconclusive FNA diagnosis and no diagnostic tissue confirmation (81 cases).RESULTS: The review FNA diagnoses were as follows: NND (49 cases), atypia (17 cases), suspicious for malignancy (12 cases), benign tumor/cyst excluding NEN (10 cases), NEN (6 cases), carcinoma (85 cases). Follow-up methods included resection (49 cases), surgical biopsy (21 cases), repeat FNA or brushing cytology (28 cases), and clinical follow-up only (81 cases). Of the 49 NND cases, 23 (47%) had positive follow-up results (i.e., false-negative diagnosis) that were confirmed by tissue diagnosis (resection/surgical biopsy in 11 cases [48%] and repeat FNA/brushing in 12 cases [52%]). These included pancreatic/ampullary adenocarcinoma in 20 cases, esophageal squamous carcinoma in 1 case, and NEN in 2 cases. Follow-up also revealed carcinoma in all 12 suspicious cases and 13 pancreatic adenocarcinomas and 1 microcystic adenoma in 14 of the 17 atypical cases. Overall, repeat computed tomography (CT)-guided FNA samples yielded a definite diagnosis in four atypical and seven NND cases, whereas EUS-FNA results provided a definite diagnosis in three cases in which CT-guided FNA failed and in two cases in which ampullary biopsy failed. No false-positive cases were identified. The false-negative rate due to inadequate sampling was 13.2%. Sensitivity (including cases with inadequate cellularity and nondiagnostic aspirates) was 81.7% and specificity was 100%. None of the factors evaluated (lesion characteristics, aspiration site, and tumor type) significantly influenced diagnostic results.CONCLUSION: EUS-FNA is a valuable diagnostic and staging tool with high specificity and sensitivity. Negative or nondiagnostic cases on EUS-FNA require further diagnostic work for a definitive diagnosis when clinical or radiographic findings do not correlate with the FNA results. 相似文献

BACKGROUND.
Relapsed or refractory mantle cell lymphoma has a very poor prognosis. The authors evaluated the response rates and survival times of patients treated with an intense regimen known to be effective against untreated aggressive mantle cell lymphoma: rituximab plus hyper‐CVAD (cyclophosphamide, vincristine, doxorubicin, and dexamethasone) alternating with rituximab plus methotrexate‐cytarabine.METHODS.
In this prospective, open‐label, phase 2 study, patients received this combination for 6 to 8 cycles. Twenty‐nine patients were evaluable for response.RESULTS.
The median number of cycles received was 5 (range, 1‐7 cycles), and the overall response rate was 93% (45% complete response [CR] or CR unconfirmed [CRu] and 48% partial response [PR]). All 5 patients previously resistant to treatment had a response (1 CR, 4 PR), and both patients whose disease did not change in response to prior therapy had PRs. Toxic events occurring in response to the 104 cycles given included neutropenic fever (11%), grade 3 or 4 neutropenia (74%), and grade 3 or 4 thrombocytopenia (63%). There were no deaths from toxicity. At a median follow‐up of 40 months (range, 5‐48 months), the median failure‐free survival time was 11 months with no plateau in the survival curve.CONCLUSIONS.
This combination chemotherapy was effective for refractory/relapsed mantle cell lymphoma. Cancer 2008. © 2008 American Cancer Society. 相似文献14.
Low-dose interleukin-11 in patients with bone marrow failure: update of the M. D. Anderson Cancer Center experience. 总被引:10,自引:0,他引:10

BACKGROUND: Recombinant interleukin (IL)-11 is a thrombopoietic growth factor. The purpose of this study was to assess the toxicity, safety and efficacy of low-dose recombinant IL-11 in patients with bone marrow failure (BMF). PATIENTS AND METHODS: Patients with BMF due to myelodysplastic syndromes (MDS), graft failure, chemotherapy or aplastic anemia (AA) were treated. Patients were required to have a platelet count of <20 x 10(9)/l, or a platelet count of <50 x 10(9)/l with an absolute neutrophil count <1 x 10(9)/l, or a hemoglobin value <10 g/dl. Treatment consisted of daily IL-11 at a dose of 10 mug/kg subcutaneously followed by a 2-week rest period. Two induction courses were given. Responders could receive maintenance therapy. RESULTS: Thirty-three patients (MDS, n=14; AA, n=16; prolonged thrombocytopenia following stem cell transplantation or chemotherapy, n=3) were evaluable. Their median age was 58 years (range 5-85). Three patients (9%) had poor risk cytogenetics. Nine patients (27%) responded to IL-11 (six MDS, three AA). Of these, three patients treated with IL-11 alone (n=1) or IL-11 together with other growth factors (n=2) showed multilineage recovery. The median time to response was 0.9 months (range 0.3-11). Factors associated with higher response rates in univariate analysis were age >50 years (P=0.008), diagnosis of MDS versus AA (P=0.025) and creatinine level >1 mg/dl (P=0.0004). The median response duration was 3 months (range 1.4-34.5+). Amongst responders, the median increment in platelet count was 111 x 10(9)/l (range 43-165). The most common side-effects were grade 1-2 lower extremity edema, conjunctival injections and fatigue. Grade 3 toxicities included arrhythmia (n=1) and transient ischemic attack (n=1). Ten patients (30%) had no side-effects. CONCLUSIONS: Low-dose IL-11 has activity in patients with BMF and is generally well tolerated. 相似文献

BACKGROUND:
Sinonasal mucosal melanoma is a rare disease associated with a very poor prognosis. Because most of the series extend retrospectively several decades, we sought to determine prognostic factors and outcomes with recent treatment modalities.METHODS:
A retrospective chart review of 58 patients treated for sinonasal melanoma at a tertiary cancer center between 1993 and 2004. The patients were retrospectively staged according to the sinonasal American Joint Committee on Cancer (AJCC) staging system. Demographic, clinical and pathological parameters were identified and correlated with outcomes.RESULTS:
There were 35 males and 23 females with a median age of 63 years; 56 patients were treated surgically and 33 received radiation therapy. According to Ballantyne's clinical staging system, 88% of the patients presented with stage I (local) disease. Classification by the AJCC staging classified yielded 27% of the patients with T1, 33% with T2, 21% with T3, and 19% with T4. T‐stage and the degree of tumor pigmentation were associated with a worse survival (P = .0096 and P = .018, respectively), while pseudopapillary architecture was associated with a higher locoregional failure (P = .0144). Postoperative radiation therapy improved locoregional control when a total dose greater than 54 Gy was used (P = .0215), but did not affect overall survival.CONCLUSIONS:
Tumor stage according to sinonasal AJCC staging system is an effective outcome predictor and should be the staging system of choice. Postoperative radiation therapy improves locoregional control when a higher dose and standard fractionations are used. Histological features such as pigmentation and pseudopapillary architecture are associated with worse outcome. Cancer 2010. © 2010 American Cancer Society. 相似文献16.

Despite that fact that a multidisciplinary approach is important for cancer treatment, this approach is not widely used in Japan. The M.D. Anderson Cancer Center (MDACC) is one of the most well-established cancer institutes in the world, and has implemented a unique multidisciplinary team management approach for the treatment of breast cancer. The efforts of MDACC to eliminate cancer have been ongoing for more than 60 years. Here, we describe the multidisciplinary approach used at MDACC for the treatment for breast cancer. We focus on the background of the institute, in terms of establishing its treatment model and educational system, and compare its multidisciplinary approach with the current approach used in Japan, in the hopes of influencing future directions in cancer therapy in Japan. 相似文献

Summary A total of 106 patients with inflammatory carcinoma of the breast underwent combined-modality treatment consisting of doxorubincin-containing chemotherapy. All patients received three cycles of 5-fluorouracil, doxorubicin, and cyclophosphamide (FAC) before local therapy. From 1974 to 1977 (group A), primary radiotherapy was the local treatment modality and chemotherapy was given for a total of 24 months. From 1978 to 1981 (group B), mastectomy became the primary local treatment modality and FAC was reinstituted within 10–14 days after surgery; after completion of FAC, consolidation radiotherapy was given. From 1982 to 1986 (group C), vincristine and prednisone were added to FAC, and doxorubicin was given by continuous infusion. The median follow-up of the three groups was 56 months. For patients alive at the time of analysis, median follow-ups were 141, 111, and 49 months in groups A, B, and C, respectively. Disease-free survival at 5 years was 35%, 22%, and 41% for groups A, B, and C, respectively, and respective overall survival at 5 years was 37%, 30%, and 48%. Mastectomy in addition to radiotherapy resulted in local control rates similar to those obtained with radiotherapy alone, but this approach would result in fewer late sequelae of high-dose irradiation and provided histologic staging for chemotherapy response. The patients treated on protocol C had slightly better disease-free and overall survival, but the differences were not statistically significant. The 5-year disease-free survival of patients achieving a clinical complete remission (CR) or partial remission (PR) was superior to that of patients whose response was less than a PR. There was no episode of doxorubicin-related cardiac toxicity in group C. Combined-modality treatment for inflammatory carcinoma of the breast resulted in improved survival. 相似文献

Lenalidomide is an oral immunomodulatory drug with significant activity in indolent B-cell and mantle cell lymphomas. Lenalidomide has a manageable safety profile whether administered as a single agent or in combination with rituximab. The combination of lenalidomide with rituximab, known as the ‘R2’ regimen, enhances efficacy over what has been shown with monotherapy and has demonstrated activity in patients considered resistant to rituximab. Tolerability of these regimens has been consistent among studies. Asymptomatic neutropenia is the most common grade 3/4 adverse event, typically managed by dose interruption, followed by dose reduction once neutrophils have recovered. Nonhematologic toxicities (e.g. fatigue) are generally low-grade, manageable with concomitant treatment, and/or lenalidomide dose modification. More frequent with R2, immune-related symptoms such as rash and tumor flare are important to recognize as lenalidomide-associated treatment effects in patients with lymphoma who require supportive care and potential dose modifications. Severe tumor flare reactions with painful lymphadenopathy are not typically observed outside of chronic lymphocytic leukemia/small lymphocytic lymphoma. Venous thromboembolism is uncommon in lymphomas, though prophylaxis is recommended. The general safety profile, differences between lenalidomide monotherapy and R2 treatment, and optimal strategies for managing adverse events are discussed here. 相似文献

Medulloblastoma is a rare adult primary brain tumor for which limited retrospective studies are available to elucidate natural history or to guide therapy. A retrospective chart and imaging review of adult patients (aged >18 years) with medulloblastoma was performed to identify survival and prognostic factors. Fifty-seven patients were evaluated at the University of Texas M.D. Anderson Cancer Center from 1978-1998. Statistical analysis of prognostic factors and overall survival was performed for a subgroup of 28 patients who were followed exclusively at our institution from the time of diagnosis until death or last follow-up. These 28 patients had an overall survival of 91% at 3 years and 84% at 5 years, whereas median survival was not reached after a median follow-up of 168 weeks (range, 9-602 weeks). Progression-free survival for all patients was 68% at 3 years and 62% at 5 years, and was not statistically different between poor- and standard-risk patients. Univariate analysis of clinical features, such as age, sex, extent of local disease, extent of resection, and use of adjuvant chemotherapy, did not identify any prognostic variables for survival among the 28 patients. Patterns of recurrence revealed that the posterior fossa was the most common site (56%), followed by bone marrow (25%). Adult medulloblastoma appears to have a favorable prognosis after treatment with maximally surgically feasible resection followed by craniospinal irradiation. Optimal treatment remains to be clarified, as both standard-risk and poor-risk patients have prolonged disease-free survival. The marked difference between survival and progression-free survival suggests that salvage therapy, usually with combination chemotherapy in this cohort of patients, is of benefit. More formal analysis of the survival benefit was not possible, however, because of the small number of patients treated at recurrence with any one therapeutic regimen. 相似文献
