RESUMO

<p><b>OBJECTIVE</b>To summarize our experiences with the treatment of non-small cell lung cancer (NSCLC) with cetuximab and compare the therapeutic effects of cetuximab applied in the first line and non-first line settings.</p><p><b>METHODS</b>From October 1, 2006 to December 31, 2009, 16 NSCLC patients were treated with cetuximab combined with standard chemotherapy in Sun Yat-sen University Cancer Center. The short-term efficacy of the therapeutic protocols were analyzed.</p><p><b>RESULTS</b>A total of 115 cycles of cetuximab treatment were administered in these patients with a median of 6 cycles (7.5 in the first line setting and 2 in non-first line setting). In the 10 patients with cetuximab treatment in the first line setting, the ORR was 40.0% (4/10), DCR was 80.0% (8/10), median TTP was 6.5 months (2-19), and median OS was 8.5 months (2-48); in the non-first line setting, these indices were 33.3% (2/6), 33.3% (2/6), 3.5 months (3-4) and 18 months (4-28), respectively. Both ORR and DCR were similar between the first and non-first line settings (P=0.790, P=0.062). Ten of the patients (62.5%) developed acne-like rash within 3 weeks, who had an ORR of 60% (6/10) and DCR of 90% (9/10); the ORR and DCR in patients without acne-like rash were both 10.4% (1/6), showing no significant difference in ORR (P=0.080) but a significant difference in DCR between the two groups (P=0.003). No treatment-associated death or cetuximab-associated discontinuation occurred. Altogether 11 patients (68.8%) developed acne-like rash, which occurred within 3 weeks in 10 cases. Seven patients showed side effects associated with the chemotherapy.</p><p><b>CONCLUSION</b>Cetuximab combined with standard chemotherapy is a good option for Chinese patients with NSCLC and the current data support the application of cetuximab in the first line setting.</p>

RESUMO

<p><b>OBJECTIVE</b>To study the efficacy and safety of cetuximab combined with chemotherapy for patients with advanced colorectal cancer (ACRC) and unclear K-ras status.</p><p><b>METHODS</b>Clinical data of 102 ACRC patients, treated by cetuximab combined with chemotherapy in Sun Yat-sen Cancer Center from March 2005 to December 2008, were collected. The cumulative survival rate, objective response rate (ORR), disease control rate (DCR), progression free survival (PFS) of the cases were calculated. The difference in ORR, DCR, PFS and oval survival (OS) between the regimens used as first-line and non-first-line treatment, and between the regimens including oxaliplatin and irinotecan were compared.</p><p><b>RESULTS</b>The overall ORR of cetuximab plus chemotherapy was 43.1%, DCR 73.5%, median PFS 4.0 months, OS 28.5 months, and the 1-year, 3-year, and 5-year survival rate was 89.2%, 50.9% and 27.5%, respectively. The differences in ORR (50.0% vs. 40.0%, P = 0.344), DCR (78.1% vs. 72.9%, P = 0.571) and OS (51.0 months vs. 35.0 months, P = 0.396) between the regimens as first line and as non-first line treatment were not statistically significant. However, the PFS of the regimen as first-line was longer than that as non-first-line treatment (PFS 5.5 months vs. 3.0 months, P = 0.001). The differences in ORR (54.2% vs. 40.0%, P = 0.223), DCR (79.2% vs. 74.7%, P = 0.654), PFS (5.0 months vs. 3.0 months, P = 0.726) and OS (36.0 months vs. 40.0 months, P = 0.759) between cetuximab plus oxliplatin and irinotecan were not statistically significant. The most common side effects of cetuximab plus chemotherapy were acneiform eruption (80.4%, grade 3-4 in 9.8%), neutropenia (66.7%, grade 3-4 in 18.6%), and diarrhea (19.6%, grade 3-4 in 5.9%). No treatment-related death was recorded.</p><p><b>CONCLUSION</b>Patients with advanced colorectal cancer and unclear K-ras treated by cetuximab combined with chemotherapy have good ORR and OS, and the regimen is safe with less adverse events for them. There is no significant difference between the efficacies of regimens as first line and as non-first line treatment, and between cetuximab plus oxliplatin and cetuximab plus irinotecan regimens.</p>

RESUMO

<p><b>BACKGROUND AND OBJECTIVE</b>Male breast cancer (MBC) in China usually has been studied retrospectively with small sample size, and studies analyzing the prognostic factors are rare. This study was to investigate the prognostic factors of Chinese patients with MBC based on the data from a single institute with a relatively large sample.</p><p><b>METHODS</b>Clinical data of 72 patients with histopathologically confirmed MBC who received treatment at Sun Yat-sen University Cancer Center between January 1969 and March 2009, were collected. Kaplan-Meier, log-rank test and Cox regression model were used for statistical analysis.</p><p><b>RESULTS</b>The 5-year overall survival rate was 72.4%, and the survival rates for stage I, II, III, and IV were 100%, 74.2%, 57.2%, and 0%, respectively. Univariate analysis showed that the tumor size (P < 0.001), axillary lymph node status (P = 0.001), TNM stage (P = 0.001), operation model (with vs. without: P < 0.001; classic radical resection vs. modified radical resection, P = 0.336) and endocrine therapy(P = 0.02) significantly influenced the survival. Multivariate Cox regression showed that TNM stage (P = 0.035), operation model (P = 0.021) and endocrine therapy (P = 0.019) were independent prognostic factors for MBC.</p><p><b>CONCLUSIONS</b>Early diagnosis and comprehensive treatment strategy consisting of surgery and endocrine treatment is essential to improve the survival of the patients with MBC, and TNM stage, operation and endocrine treatment are the significant prognostic factors for MBC.</p>
