A Phase II study of the Src family kinase (SFK) inhibitor dasatinib was recently reported in molecularly unselected patients with metastatic NSCLC. SFK inhibition has a strong rationale as a clinical strategy in NSCLC. The reviewed study unfortunately showed disappointing activity as monotherapy in this molecularly unselected patient cohort and toxicity in terms of pleural effusion was problematic. Therefore, dasatinib as monotherapy in this setting does not appear promising. Nonetheless, the reviewed study may be used in conjunction with other studies of dasatinib in NSCLC to identify patients more likely to benefit from dasatinib either as monotherapy or in combination with other agents. Future studies of dasatinib in NSCLC should examine the agent in combination with EGFR inhibitors and/or cytotoxic chemotherapies. 相似文献

BACKGROUND:
Postprostatectomy adjuvant or salvage radiotherapy, when using standard fractionation, requires 6.5 to 8 weeks of treatment. The authors report on the safety and efficacy of an expedited radiotherapy course for salvage prostate radiotherapy.METHODS:
A total of 108 consecutive patients were treated with salvage radiation therapy to 65 grays (Gy) in 26 fractions of 2.5 Gy. Median follow‐up was 32.4 months. Median presalvage prostate‐specific antigen (PSA) was 0.44 (range, 0.05‐9.50). Eighteen (17%) patients received androgen deprivation after surgery or concurrently with radiation.RESULTS:
The actuarial freedom from biochemical failure for the entire group at 4 years was 67% ± 5.3%. An identical 67% control rate was seen at 5 years for the first 50 enrolled patients, whose median follow‐up was longer at 43 months. One acute grade 3 genitourinary toxicity occurred, with no acute grade 3 gastrointestinal and no late grade 3 toxicities observed. On univariate analysis, higher Gleason score (P = .006), PSA doubling time ≤12 months (P = .03), perineural invasion (P = .06), and negative margins (P = .06) showed association with unsuccessful salvage. On multivariate analysis, higher Gleason score (P = .057) and negative margins (P = .088) retained an association with biochemical failure.CONCLUSIONS:
Hypofractionated radiotherapy (65 Gy in 2.5 Gy fractions in about 5 weeks) reduces the length of treatment by from 1‐½ to 3 weeks relative to other treatment schedules commonly used, produces low rates of toxicity, and demonstrates encouraging efficacy at 4 to 5 years. Hypofractionation may provide a convenient, resource‐efficient, and well‐tolerated salvage approach for the estimated 20,000 to 35,000 US men per year experiencing biochemical recurrence after prostatectomy.

BACKGROUND: The incidence of brain metastases (BM) from colorectal cancer (CRC) is increasing, and the management of this previously rare complication at a single institution is reported. METHODS: The records of all patients with BM from 1994 to 2005 were reviewed, and 49 patients (33 men, 16 women) with 102 BM from CRC were identified. Associations between patient and tumor characteristics, treatment modality, and survival were assessed. RESULTS: The median age at diagnosis of BM from CRC was 66 years. Forty patients (82%) had other systemic disease. The median survival after a diagnosis of BM from CRC was 5.1 months. Fifteen patients (31%) underwent surgery at some point, 14 patients (29%) underwent stereotactic radiosurgery (SRS), and 42 patients (86%) received whole-brain radiotherapy during their management. Seven patients (14%) underwent upfront SRS. On multivariate analysis, a longer interval from diagnosis of CRC to diagnosis of BM was associated significantly with shorter survival (p = .01). Sex, Karnofsky performance status, tumor location, recursive partitioning analysis class, and initial treatment modality did not have an impact on survival. CONCLUSIONS: Because BM from CRC are a late-stage phenomenon, the majority of patients in the current study had other systemic involvement, and survival after CNS involvement was poor. The results indicated that a high prevalence of systemic disease limits the proportion of patients who are strong candidates for upfront SRS, thereby limiting the impact that this modality has on outcomes in this population as a whole. Late development (>1 year after the primary tumor diagnosis) of CNS involvement may predict for poorer survival after therapy for patients with BM from CRC. 相似文献

Recent reports have noted higher rates of heterotopic ossification (HO) with surface replacement arthroplasty (SRA) than with traditional total hip arthroplasty in the absence of postoperative HO prophylaxis. This study reports rates and grades of HO in 44 SRA patients with at least 1 year of follow-up. Heterotopic ossification prophylaxis was used in 32 (73%) of 44 cases. Heterotopic ossification prophylaxis consisted of radiotherapy (22/32), nonsteroidal anti-inflammatory drugs (8/32), or both (2/32). One case of clinically significant HO was documented in the no-prophylaxis group. This strategy of selective HO prophylaxis in patients felt by orthopedic surgeons to be at high risk of HO resulted in low rates of clinically relevant HO after SRA (1/44, 2.3%). Further study is needed to establish optimal selection criteria for HO prophylaxis after SRA. 相似文献
