Advanced basal cell carcinoma (aBCC) includes metastatic and locally advanced BCC that is inoperable (or with surgery contraindicated). We describe patient characteristics and treatment history for aBCC cases from community oncology. Nine cases of aBCC were found within the ACORN Data Warehouse, a community oncology database of >180,000 cancer patients. Data were summarized descriptively. Three illustrative case histories are presented. Patients were predominantly Caucasian (8/9), male (6/9), and over 60 (6/9). Four had metastatic disease; five had aBCC without metastasis. Five had a history of treatment for early stage BCC, including surgery (5/5), radiation (1/5), and none had chemotherapy. Those with history of early stage BCC had periods of apparent lack of follow-up and treatment. One had chemotherapy for aBCC (platinum based with radiation) and eight had radiation without chemotherapy. Patients had multiple comorbid serious medical conditions. Six were deceased, but only one was documented to have aBCC as cause of death. Advanced BCC is rare in community oncology settings. There appear to be gaps in the care and follow-up of patients with initial early stage BCC. More data and larger samples are needed from multi-specialty databases such as dermatology and head and neck surgery.
470 Background: While colon cancer (CC) is predominantly a disease of the elderly, older patients are underrepresented in clinical trials. We sought to evaluate whether the treatment patterns and benefits realized by trial participants pertain to older patients in the real-world setting. Methods: Using the linked Surveillance, Epidemiology, and End Results (SEER)-Medicare database, we conducted a retrospective cohort analysis of 3390 stage II and III CC patients diagnosed between 1/1/ 2004 to 12/31/2007, who were >66 years, enrolled in Medicare Parts A and B, and received adjuvant treatment with 5FU/LV (n=1368), FOLFOX (n=1398), CAP (capecitabine; n=507), and CAPOX (CAP + oxaliplatin; n=117) within 3 months after surgery. Date of last follow-up was 12/31/2007. Chi-square test and ANOVA or t-test assessed differences in patient and disease characteristics by treatment. Propensity score weighted Cox regression assessed the relative risk of death by treatment. Results: Patients treated with CAP were older (mean age 77 years; p<.0001), more likely female (61%; p<.05), more likely non-white (19%; p<.05) and had higher co-morbidity score (p<.0001) compared to the other treatment groups. The mean time to chemo initiation after surgery were similar between the groups (mean 46-49 days) while mean duration of treatment were longer for 5FU/LV (149 days) and FOLFOX (144 days), compared to CAP (121 days) and CAPOX (111 days); p<.0001. The incidence of adverse events (AEs) within 180 days after initiation of treatment were higher in patients treated with FOLFOX (82%) and 5FU/LV (78%) compared to CAP (74%) and CAPOX (71%); p=0.0002. Propensity score adjusted multivariate analysis demonstrated comparable survival for CAP-based regimens vs. 5-FU/LV- based regimens ( table ). Conclusions: Treatment outcomes for elderly patients observed in routine clinical practice were comparable between CAP-based and 5FU/LV-based regimens and consistent with results reported in randomized clinical trials. AEs associated with medical resource utilization were less frequent with CAP-based regimens. [Table: see text]
Purpose Treatment advances have improved outcomes in clinical trials of patients with metastatic colorectal cancer (mCRC). Less is known about these effects for patients in real-world settings. This study evaluated treatment patterns and survival in older, demographically diverse patients with mCRC. Results Compared to 5-FU/LV, patients treated with CAP were older (mean age 78 vs. 76; P< 0.0001) and more likely female (61 vs. 54 %; P00.0017), while patients receiving CAPOX and FOLFOX were similar in age (mean age 74 vs. 73; P00.0924). Complications requiring medical resource utilization following initiation of therapy were significantly higher among patients administered with 5-FU/LV (54 %) vs. CAP (17 %; P < 0.0001) and FOLFOX (75 %) vs. CAPOX (57 %; P < 0.0001). The multivariate analysis revealed no significant differences in survival between 5-FU/LV and CAP and between FOLFOX and CAPOX. Conclusions Overall survival was comparable between CAP and 5-FU/LV and between CAPOX and FOLFOX with fewer complications requiring medical resource utilization associated with CAP and CAPOX, thus confirming clinical trial results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
